When we buy luggage, most people focus on the size, material, and how it looks. But actually, the wheels are one of the most important parts. If the wheels are not strong, even a good suitcase will break easily after a few trips. That’s why PU wheels (polyurethane wheels) are becoming more and more popular in the luggage industry. As a factory making PU wheels for many years, we want to share why we recommend using PU wheels for your luggage.   1. PU Wheels Are Strong and Wear-Resistant PU material is very suitable for luggage wheels. It’s not too hard like plastic, and not too soft either. The wheels can withstand long-distance rolling, and even on rough roads, they don’t wear out easily. Many brands now use PU wheels instead of traditional PVC or plastic ones. In our tests, PU wheels can last longer and reduce the chance of customer complaints.   2. Rolling Smooth and Quiet No one likes noisy wheels. Traditional wheels often make loud sounds when dragging on the ground, especially in airports or quiet places. PU wheels are more silent and smooth. The material has a soft surface, so it reduces noise and vibration. Some of our customers told us their buyers said, "It feels like gliding, very quiet and smooth."   3. Better Shock Absorption Luggage is often pulled over uneven roads, steps, or curbs. PU wheels have good shock absorption, which means the suitcase doesn’t shake too much. It also helps protect the things inside the luggage, especially if the traveler is carrying glass bottles, electronics, etc.   4. Good Flexibility and Control We make 360-degree spinner PU wheels, which means the wheels can rotate in any direction. This makes it easier for travelers to move around in tight spaces, airports, or public transport. Even when the luggage is fully packed and heavy, PU wheels are still easy to move.   5. Modern Look and Custom Options PU wheels look nicer than many other types. They have a clean, shiny finish and can be customized in different colors. Some customers also like light-up PU wheels, especially for kids’ luggage or travel bags with special design.

With the improvement of quality of life, people often place ornaments such as fish tanks in living rooms and office spaces to decorate the environment. Such ornaments need to be both decorative and ornamental. For example, small-scale ecosystems are formed by combining LED lights with flower arrangements and fish tanks. However, in existing technologies, the light source components need to be externally powered through power cords, which limits the use of the device, making it impossible to flexibly move it to areas far from power sources. Additionally, power cords affect the aesthetics, lead to complex wiring, and are inconvenient to adjust. To solve the limitation of "external power supply," this patent proposes a self-generating lighting device that uses mechanical structures and the principle of electromagnetic induction for autonomous power supply, eliminating dependence on power cords and meeting users' needs for flexible movement and convenient use of ornaments.   Detailed Structural Features 1)  Water Wheel Structure ：The water wheel consists of a first frame and a second frame that are combined left and right. An installation position is provided in the middle for fixing the winding component. The water flow pushing parts are evenly arranged along the circular edge of the frames, and when the two frames are combined, the water flow pushing parts are arranged at intervals, resulting in a uniform and compact structure. The frames are also equipped with groove positions for positioning the light-emitting lamps, facilitating their fixation. 2)  Water Flow Pushing Parts ：Shaped like plates, the water flow pushing parts form water injection areas between adjacent parts. When water flows into the water injection areas, it pushes the water wheel to rotate. 3)  Winding Component ： Comprising a coil and a circuit board, the winding component is electrically connected to the light-emitting lamps via the circuit board. The winding component is encapsulated with a sealing glue layer to provide waterproofing and protect internal components. 4)  Bracket and Central Shaft ： The bottom of the bracket is provided with connection holes, through which the device can be fixed with screws. The end of the central shaft is square-shaped, matching the square holes on the bracket to ensure the central shaft remains fixed and does not rotate. 5)  Material Selection ： The water wheel is made of light-transmitting materials such as PP, PVC, PC, or PS. When the light from the light-emitting lamps shines on the water wheel, it produces a light-transmitting effect, enhancing the ornamental value.   Working Principle When water flows against the water-pushing components on the edge of the water wheel, the water wheel starts to rotate.  As the water wheel spins, the relative motion occurs between the winding components and magnetic parts in the generator core installed at the connection point of the water wheel and the central shaft.  The coils cut the magnetic field lines in the magnetic field, generating induced current.  This current is transmitted to the light-emitting lamp through the circuit board, causing the lamp to light up and emit a soft and beautiful glow.  Meanwhile, since the water wheel is made of light-transmitting material, light can pass through it, creating a unique visual effect and further enhancing the ornamental value of the device.   Advantages ●  Self-generating Design : The rotation of the water wheel drives the generator core, eliminating the need for an external power source and making it more flexible and convenient to use. ●  Compact and Ingenious Structure : All components are closely coordinated with a reasonable overall design, ensuring the device's stability and durability. ● Excellent Waterproof Performance : The sealing glue layer of the winding components effectively prevents water intrusion, extending the device's service life. ●  Outstanding Decorative Effect : The light-transmitting water wheel combined with the light-emitting lamp creates a unique visual effect, suitable for various decorative scenarios. ●  Easy Installation and Fixation : The connection holes at the bottom of the bracket allow the device to be easily fixed in different positions, enhancing usage flexibility.

Technical Background     During a child's growth, balance bike serve as indispensable transitional tools, with their core function being the development of balance skills. However, traditional baby walker balanced bike have relatively simple functions, generally lacking self-powered lighting capabilities. They mainly rely on external decorations or passive reflective components for safety warnings, posing hidden dangers due to insufficient visibility during nighttime use, while also lacking fun and innovation.       To address these issues, we have developed a self-powered illuminated balance bike. This balance bike not only retains the basic functions of traditional models but also achieves autonomous power supply for the vehicle lights through a unique self-power generation design, significantly enhancing the functionality and entertainment value of the balance bike.   Core Structure and Self Generator Wheel Principle 1. Overall Structure ：The body of the balance bike is designed in a hollow and interconnected shape, facilitating internal wiring. The body is equipped with a connecting shaft, on which the wheels are rotatably mounted. An external power generation component is installed on the wheels, electrically connected to the lighting fixtures. This component generates electricity through the principle of electromagnetic induction, providing power for the balance bike's lights and achieving self-power generation.   2. External Power Generation Component ：The external power generation component is one of the core parts of the balance bike, composed of a first magnetic ring and a first wire coil winding. The first magnetic ring is rotatably arranged on the outer side of the first wire coil winding. When the wheel rotates, the first magnetic ring cuts the magnetic field lines relative to the first wire coil winding, generating induced current. The current is transmitted to the lighting fixtures through wires. This power generation method cleverly utilizes the rotational energy of the wheels to achieve energy conversion and utilization.   3. Lighting Fixture System ：The system includes a headlight, taillight, and body light strips, all powered by the external power generation component without the need for additional batteries, making it energy-saving and environmentally friendly. The lighting fixtures not only enhance the aesthetic appeal of the balance bike but also improve its visibility in low-light environments, enhancing safety.   4. Installation Wires and Wiring System ：The balance bike also includes mounting parts connected to the connecting shaft for fixing the external power generation component. The mounting parts are pre-provided with wire slots where wires can be accommodated, preventing the wires from being exposed and improving the overall aesthetics and safety.         Technical Advantages ●  Energy-saving and Environmentally Friendly : The self-power generation design of the wheels not only provides stable power for the vehicle lights but also eliminates the inconveniences of traditional battery power supply, such as battery replacement and charging issues.   ●  Compact Structure : The structural design and material selection of the vehicle body ensure the durability and safety of the balanced bike light up wheel. The hollow design of the body and the use of bearings enable the balance bike to maintain lightness while ensuring sufficient strength and stability.   ●  Safe and Reliable : The hidden wiring design of the wires and the smooth rotation of the bearings reduce potential safety hazards caused by exposed wires and wheel shaking.   ●  Upgraded Functions : The addition of headlight, taillight, and body light strip designs not only provides good lighting in nighttime or dimly lit environments but also enhances the visibility of the balance bike, improving the safety of children during riding.                        

Daily-used trolley bags, suitcases, baby strollers, shopping carts, and transport carts all include trolleys. As a core tool for carrying and moving, most trolleys on the market currently have limitations in structure and function. For example, they only optimize the original structure and lack practical functions such as self-generated power and lighting. With the development of society, people have higher requirements for the practicality and functionality of trolleys. Against this background, the patent "A Self-Generating and Lighting Trolley" came into being.   Self-power Generation System: Core Innovation The self generator wheel operates on the principle of electromagnetic induction, with core components including: ● Stationary Components : Lead parts (with built-in circuit channels) and winding groups, fixed to the frame mounting feet and transversely secured by bolts. ● Rotating Components : A magnetic ring, hub, side cover, and tire, rotationally connected via a first bearing and a second bearing. When the trolley moves, the magnetic ring rotates with the hub, and the winding groups cut magnetic field lines to generate current. The current is transmitted through lead wires via the circuit channels to the control board, and then to the lighting components. The sealing design (side sealing cylinder) of the self generator wheels and its bearing structure ensure dust and water resistance, enhancing durability.   Lighting Components: Enhancing Visibility and Safety The design of the lighting components aims to improve the visibility of the trolley in nighttime or low-light environments and enhance usage safety. The lighting components can be flexibly configured according to actual application scenarios. These components can be light strips or headlamps, respectively installed on the shaft body and pallet of the frame, ensuring the vehicle's visibility in various environments.   Working Principle : Efficient Conversion from Kinetic Energy to Light Energy During the pushing or pulling of the trolley, the tire of the power-generating wheel drives the hub and magnetic ring to rotate. The winding group remains stationary and cuts through the magnetic field of the magnetic ring, generating induced current. The current is transmitted via lead wires to the control board at the bottom of the frame. After the control board stabilizes the current, it is output to each lighting component. This process requires no external power supply or built-in battery, achieving continuous power supply through pure mechanical kinetic energy conversion, which is both environmentally friendly and economical.   Compared with traditional trolleys, this patented technology has significant advantages. Its self-powered lighting eliminates dependence on external power sources, making it suitable for no-light scenarios such as nighttime shopping, outdoor handling, and emergency rescue, thereby improving safety. The integrated design of the power-generating wheel and the frame does not significantly increase volume or weight, maintaining the portability of the trolley. The flexible configuration of lighting components enables it to adapt to multiple product categories such as hand carts, shopping carts, and strollers, expanding the boundaries of market applications. The bearing and sealing structure design ensures the stable operation of the power-generating wheel in complex environments and prolongs the product lifecycle.

In roller skating devices such as scooters and roller skates, the application of flashing wheels not only enhances the entertainment value but also improves the safety during nighttime use. However, most traditional luminous wheels are made of materials like PU, TEP or PVC through injection molding to form a solid structure, which has the following drawbacks: Firstly, a large amount of materials is used and the weight is heavy, resulting in high production costs. Secondly, the solid structure has poor light transmittance, making it difficult for the light from the lamp beads to be evenly emitted, and the luminous effect is not ideal. Thirdly, the overall structure is complex, and the assembly convenience is insufficient. In response to the above problems, we have developed a luminous wheel using the blow molding process. Its core lies in combining the hollow blow-molded wheel body with the integrated luminous component, and achieving performance breakthroughs through structural optimization.   Hollow Blow-molded Wheel Body The wheel body is manufactured by the blow molding process and has a hollow structure inside. Compared with the traditional solid wheel body, it has two core advantages:● Optimization of materials and weight : The hollow structure significantly reduces the amount of materials used, thereby lowering the production cost. At the same time, the quality of the wheel body is remarkably reduced. When assembled into external products such as scooters and roller skates, the overall structure is lighter, improving the flexibility of use. ● Enhancement of light transmittance performance : The hollow design improves the light transmittance of the wheel body, allowing the light from the lamp beads to be evenly emitted through the wheel body, resulting in a more transparent and brighter luminous effect. Integrated Luminous Component The luminous component is installed in the assembly position of the wheel body, and its design takes into account both functionality and convenience:● Layout of lamp beads : The lamp beads are distributed in a divergent shape at equal intervals and are precisely embedded in the lamp positions of the wheel body's assembly position, ensuring that the light evenly covers the surface of the wheel body and forming a continuous and stable light effect when rotating. ● Detachable shell : The shell adopts a split combination type (such as left and right snap connection) or an injection-molded integrated type, which protects the internal coils and circuit boards, taking into account both convenient installation and structural stability. ● Design of holes and bearings : The first hole position in the center of the wheel body corresponds to the second hole position of the luminous component, and double bearings are installed through the limited positioning of the bearings to ensure a stable rotational connection between the wheel body and the external connecting rod.   Working Principle The lighting assembly consists of a coil winding, a circuit board, and LED beads, all electrically connected. A magnetic core, rotatably assembled with the lighting assembly, generates an outward-facing magnetic field. As the wheel rotates, the coil winding cuts through the magnetic field lines, inducing an electric current. This current is then transmitted via the circuit board to the LED beads, causing them to illuminate—functioning similarly to existing dynamo wheels.   Advantages ● Cost and Weight Reduction : The blow-molded hollow wheel design minimizes material usage, lowering production costs while reducing overall weight for enhanced portability and usability. ● Superior Light Transmission and Illumination : The blow-molded wheel’s high transparency allows light to evenly permeate the entire wheel, resolving issues of poor light dispersion and dim illumination common in traditional solid tires. ● Structural Stability and Aesthetics : The lighting assembly is mounted on the inner side of the wheel, with the protective casing slightly protruding. This not only enhances visual appeal but also shields the components from abrasion during use, extending product lifespan and reliability.  

The traditional light up wheels (such as the wheels for skates and scooters ) usually install components like coils and light-emitting beads inside the wheel hub and fix them by one-piece injection molding. This design has many defects: once the coil or light-emitting bead is damaged, the entire wheel hub usually needs to be scrapped, causing waste of resources; moreover, for the diverse light-emitting effects formed by different combinations of coils and light-emitting beads, the traditional structure cannot be flexibly disassembled and replaced, which greatly limits the playability and functionality of the product. The utility model aims to provide a detachable and maintainable light-emitting wheel structure, which solves the problems of high maintenance cost and insufficient flexibility in the traditional technology by improving the installation mode of the wheel hub cover and the light-emitting component.   Wheel Hub Cover Structure The wheel hub cover is made of light-transmitting materials, with an internal installation position where a rotor is placed. The rotor is electrically connected to the light-emitting lamp. The cover body is also equipped with a connecting component for connecting to the wheel hub. The rotor is wrapped with a fixed shell, which can be an integral structure or a split left-right buckling structure. A stepped position is provided around the fixed shell, and the first clamping foot in the installation position is clamped with the stepped position to achieve detachable installation of the rotor.   Light-Emitting Wheel Structure The flashing wheels includes the above-mentioned wheel hub cover and wheel hub. The wheel hub is provided with a slot matching the connecting component to facilitate the installation and disassembly of the wheel hub cover. A horizontal shaft is rotatably arranged in the middle of the wheel hub, and the horizontal shaft is connected to a stator. When the cover body is assembled to the wheel hub, the stator is located inside the rotor. When the rotor rotates relative to the stator, it cuts the magnetic field lines to generate electric energy, driving the light-emitting lamp to emit light. The rotor is a winding of wire coils, and the stator is a magnetic body. The end of the horizontal shaft is provided with a knurled head, and a clamping slot is arranged in front of the knurled head. The stator is closely assembled on the knurled head, and a washer and a snap ring are used in combination to ensure the stator is firmly installed.   Dual-Scene Installation Scheme ●  Low-Speed Scenario Configuration (such as strollers) : The horizontal shaft directly passes through the wheel hub, and a knurled head is arranged at the end to enhance friction with the stator. The stator is fixed by matching washers and circlips to prevent axial loosening. ●  High-Speed Scenario Configuration (such as roller skates) : The wheel hub is connected to the horizontal shaft through a bearing to ensure smooth high-speed rotation. The stator is fixed to the horizontal shaft via a connector with external threads, and the knurled section is positioned by a pin to improve stability. The convex ring of the stator corresponds to the inner ring of the bearing, without affecting the normal operation of the bearing.   Technical Advantages ●   Convenient Maintenance : The rotor is integrated into the wheel hub cover. In case of a fault, only the cover needs to be disassembled for replacement, without damaging the wheel hub structure, which reduces maintenance costs and resource waste. ●  Functional Flexibility : Supports quick replacement of wheel hub covers with different light effects. Users can switch light effects (such as colors and patterns) according to needs, adapting to diverse scenarios. ●   Structural Reliability : The combination of a clamping design with fixing methods such as knurling and pins ensures the stability of components during low and high-speed rotations, balancing operational convenience and mechanical strength.

Skateboarding originated in the late 1950s and early 1960s and evolved from surfing. Nowadays, it has become an extreme sport deeply loved by young people. The traditional skateboard structure is relatively stable and usually consists of a board body, a bracket and wheels. Although it meets the basic sliding requirements, it is lacking in terms of fun and functionality, especially in the light effect. Against this backdrop, a new type of power-generating skateboard has emerged, aiming to bring a brand-new experience to skateboard enthusiasts.   The Structure Of The New Type Of Power Generation Slide Plate ● The new type of power generation skateboard is mainly composed of the board body, bracket, wheels, power generation components and light effect components. All parts work closely together to achieve a complete functional chain from kinetic energy to electrical energy and then to the presentation of light effects. The board body serves as a platform for the user to stand on. The bracket connects the board body with the wheels, providing support and stability for the skateboard. The paired wheels ensure the flexible movement of the skateboard. ● The power generation component is located inside the wheels and is the key technology. The winding frame winds the coil group, with a metal cutting disc on the outside. Both are connected to the circuit board, and the circuit board is also connected to the output wires and LED lights. When the wheel rotates, the magnetic ring and the coil group cut the magnetic field lines to generate current, achieving the conversion of kinetic energy to electrical energy. ● The light effect components are on the board body and consist of LED beads and light guide parts. The first and second light guide strips of the light guide component are respectively wrapped around the edge and the inner side of the plate body. After the LED light emits light, the light conduction causes the light guide strip to glow, creating a two-circle luminous effect. Moreover, the lights at both ends of the light guide strip enhance the bright effect. ● The output wires are connected to the power generation and light effect components. There are springs in the wire grooves of the bracket to fix the wires, and the wire outlet holes at the top are connected to the interior of the board body. The wheel is composed of a hub, an installation housing and a tire. The magnetic ring is installed inside the installation housing. The installation housing and the hub are fixed by the fit of the clips, slots and screws. The wire transition piece on the wheel limits the wire to ensure the stability of the structure.   The Unique Functions And Advantages Of Skateboards ● The self-generation function enables energy self-sufficiency: When the skateboard wheels rotate, the power generation component generates current, which not only supplies power to the light effect component but also lights up the leds on the circuit board. This self generator wheel function enables the skateboard to operate without an external power source, achieving energy self-sufficiency, which is both environmentally friendly and convenient.   ● Rich lighting effects enhance entertainment experience: The design of the lighting components enables the skateboard to present dazzling lighting effects during the process. The inner and outer light guide strips emit light, combined with the illuminated lights at the front and rear ends, as well as the projectors that can be installed on the body. The projectors can project patterns onto the ground, greatly enhancing the fun and entertainment of the skateboard and providing users with a unique sliding experience.   This new type of power-generating skateboard, with its innovative design and unique functions, has broad application prospects in the skateboard market. For skateboard enthusiasts, it meets the demand for personalized and interesting skateboards. In business activities, it can be used as a special performance prop or a display tool to attract customers. In leisure and entertainment venues, such as theme parks and shopping malls, they can also become popular experience projects.

In the field of leisure sports, roller skates, scooters, and skateboards have long been beloved by the public, offering both entertainment and opportunities for physical exercise. However, traditional sports equipment of these types has limitations in data collection. Modern sports devices, by contrast, often incorporate relevant equipment to quantitatively analyze human movement data, providing feedback or regulatory functions. Therefore, the present utility model aims to improve this situation by providing a data collection device, which is applied to riding supplies such as ice skates, scooters and skateboards. This data collection device is mainly composed of an installation base and a wheel body. The wheel body is rotatably mounted on the installation base, similar to how wheels are commonly installed on a vehicle frame. Its distinct feature is that the installation base is equipped with a magnetic sensor, while a corresponding magnetic body is installed on the wheel body. As the wheel body rotates, the magnetic body moves in tandem; each time the magnetic body approaches the magnetic sensor, the sensor captures a signal. By analyzing these signals, the rotational speed and number of revolutions of the wheel body can be easily determined, allowing for the collection of motion-related data that provides strong support for subsequent movement analysis. ● To present data more intuitively, the magnetic sensor can also be connected to a display component, with connection methods including wired or wireless options. The specific design for connecting the control module and communication device includes components such as a control unit, wireless communication unit, or wired communication unit. ● The structural design of the device incorporates thoughtful details. It is equipped with a retaining ring, on which the magnetic sensor is mounted. The retaining ring has retaining edges on both sides, which align with corresponding retaining slots on the installation base; alternatively, the retaining ring may have slots and the base may have edges. This interlocking design of slots and edges allows the magnetic sensor and retaining ring to be easily installed on the installation base, significantly improving assembly convenience. ● The wheel body features a unique design: it includes a hub with an assembly groove where the magnetic body is securely embedded. Both the assembly groove and the corresponding magnetic sensor are positioned on the inner side of the hub. This layout protects the magnetic body and sensor from scratches during use, effectively preventing detachment and ensuring the device’s stability and reliability.     This data collection device is perfectly compatible with roller skates, scooters, and skateboards. In these three types of sports equipment, the installation base serves as a wheel frame to mount the wheel body. As the scooter wheel,wheels for skates,Skatebaord wheels body rotates, the interaction between the magnetic body and the magnetic sensor generates signals, enabling data collection. The collected data is transmitted to a display component, which can take various forms—handheld, wearable, or mounted on the handlebars of scooters—allowing users to easily view their motion data.   The beneficial aspect of this utility model lies in that the rotation of the wheel body drives the movement of the magnetic body, and the magnetic sensor captures signals to achieve data collection. The device can be integrated into roller skates, scooters, and skateboards to meet the need for data collection during exercise, providing users with a convenient and effective solution for collecting exercise data. This helps enhance the sport experience and training effectiveness.    

In skating, traditional shoe racks have a single function and can only meet the basic skating needs, with poor functionality and entertainment. To address this pain point, an innovative skate rack integrating power generation and lighting functions has emerged. By converting sliding kinetic energy into electrical energy, it enables the edge of the rack to emit light and supplies power to external devices, infusing technological and entertainment elements into the sliding experience. Core Design The shoe rack body is equipped with a power generation wheel. The inner wall of the outer wheel is fixed with a magnetic ring, and the internal bracket is installed with a stationary metal coil group and a second circuit board. When sliding, the rotation of the outer wheel drives the magnetic ring to rotate. The coil cuts the magnetic field lines to generate current, which is transmitted through the circuit board to the first circuit board on the shoe rack to supply power to the electrical components. The electrical components are centered around the first-line road board and connected to the light-emitting band that surrounds the edge of the shoe frame. When sliding, they automatically light up to create a surrounding lighting effect. The circuit board also reserves two expansion power cords: one extends to the toe of the shoe to support the connection of external lighting lamps, and the other is connected to the electrical components of the upper/LACES and other parts in a free end form, achieving a personalized lighting design for the entire shoe body.   Core Construction Principle The power generation wheel is the core component for achieving kinetic energy conversion. Its structure takes into account both power generation efficiency and installation stability. Through the electromagnetic induction principle of "magnetic ring rotation - coil power generation", combined with details such as planar anti-slip and wire trough storage, the power generation wheel generates electricity by sliding, providing continuous power for the skaters, and balancing functionality and stability. ● Power Generation core : The inner wall of the outer wheel is fixed with a magnetic ring, and the internal bracket is equipped with a metal coil group and a second circuit board. When sliding, the magnetic ring rotates along with the outer wheel. The coil cuts the magnetic field lines to generate electricity, which is then powered after being processed by the circuit board. ● Stable Installation : The bearings on both sides of the outer wheel are embedded in the wheel and sleeved on the connecting shaft of the assembly seat. The connection holes between the connecting shaft and the bracket are set with corresponding planes to fit and prevent slipping. The bracket is perforated for wiring. ● Assembly Design : The assembly base is fixed to the shoe rack through the installation rod, the surface wire trough stores the power cord, and the cover plate conceals the circuit. The bearing groove position is adapted to the general cylindrical shaft, simplifying the processing.     Advantages And Highlights ● Self Generator Wheel Technology  : No external power supply is required. It generates electricity naturally through sliding to power the light-emitting strips and external devices, saving energy and avoiding the trouble of battery replacement. ● Diversified Expansion : The reserved power cord interface supports personalized modifications such as toe lighting and upper decoration, meeting users' diverse demands for LED skate wheels effects. ● Visual Effects : The cool appearance of the surrounding luminous strips enhances the recognition and entertainment value during gliding, making it especially suitable for night sports or performance scenarios. ● Stable Structure : The optimized design of bearings, assembly seats and brackets ensures smooth rotation of the power generation wheel. Meanwhile, the hidden layout of power lines prevents line wear and avoids the risk of entanglement, enhancing the safety of use light up roller wheels.    

In daily life, means of transportation such as scooters, toy cars, bicycles and baby strollers are indispensable, and the wheels are the key components of these tools. Nowadays, to enhance the fun and practicality of the products, many skateboards and roller skates are equipped with flashing wheels. However, the existing light-emitting wheels have obvious deficiencies. The visual effect is very monotonous and cannot meet children's pursuit of novel and unique experiences. Against this background, we have developed a new type of light effect box and its light-emitting wheels, which can bring new possibilities to this pain point. The Exquisite Design Of The Light Effect box ● Materials And Structure The core of the light effect box is the light effect box itself. It is made of translucent materials, such as transparent or semi-transparent PC, PP, PS, etc. Some of them also have reflective effects, which can serve as a safety warning when the wheels are not glowing. In the middle of the light effect box body, there is a storage cavity for installing the light-emitting lamp components. Around the storage cavity, several light-emitting channels are distributed in a radial pattern. This divergent design provides a foundation for a unique visual effect. ● Luminous Efficacy End And Luminous Efficacy Point The luminous effect end at the end of the light-emitting channel is uniquely designed. It is shaped like a condenser lens of an LED lamp head and can be designed in various shapes such as circular, arc-shaped, square, and rhombus, which can gather light and enhance the luminous effect. On the inner walls of the light-emitting channels and the light effect ends, there are numerous light effect points of various shapes and sizes. When light shines on them, it causes scattering, allowing the light to be evenly distributed on the main body of the light effect box and creating a charming light effect. ● Printed Patterns And Split Structures The surface of the light-emitting channel can be printed with light effects, featuring various exquisite patterns. When illuminated, the patterns appear, enriching the visual effect. The main body of the light effect lamp box adopts a detachable design and is composed of the first box body plate and the second box body plate. The assembly column of the first box body plate fits with the assembly hole of the second box body plate to ensure a stable combination of the two. In special cases, plastic ultrasonic fusion technology can also be used for reinforcement. This split structure is convenient for installing the light-emitting lamp components and can also protect the components during injection molding, thereby enhancing durability.     The Principle Of Power Generation And Light Emission Based on this light effect lamp box, a brand-new light-emitting wheel has also been born. This new type of light-emitting wheel contains a hub, and the light effect lamp box is installed inside the hub. The light-emitting lamp assembly in the storage cavity consists of a power generation mechanism and a light-emitting lamp (LED lamp). The power generation mechanism employs existing technologies, including circuit boards, magnetic coils and induction coils. When the wheel rotates, the relative motion between the induction coil and the magnetic coil cuts the magnetic field lines, generating current and lighting up the light-emitting lamp.   The Design Of The Wheel Hub The side of the wheel hub is provided with grooves and gaps. After the light effect lamp box is assembled, the light emission channel is in the groove and the edge of the light effect lamp box is in the gap. Their presentation states are diverse. One can be convex and the other concave, or both can be concave or convex. This design allows light to pass through the light-emitting channel, the light-emitting edge (when the edge of the light effect box protrudes), or the gap (when the edge of the light effect box is concave), creating a brilliant visual effect. The concave position at the circumference of the wheel hub allows the luminous end to protrude, which not only increases the light-emitting area but also protects the luminous end from being squeezed. During production, the combination method of the light effect lamp box and the wheel hub is flexible. It can be integrally injection molded or separately pressed into boxes.  

1. Traditional predicament: The limitation of power supply restricts development In the scooters, toy cars, trolleys and shelf carts we use in our daily life, the rotating wheels are indispensable components. Take the skateboard wheels as an example. To enhance entertainment and functionality, some skateboard are equipped with flashing wheels. These wheels cut the magnetic field lines by the rotation of the magnetic coil and the winding coil group, allowing the light-emitting diodes to emit light. However, this method has limitations. The current generated can only be used by the internal light-emitting diodes and cannot be sent out. If it is sent out through wires, it will cause the wires to tangle and break. Therefore, there has never been a power self generator wheel that can supply power both internally and externally, which has restricted the application and development of rotating wheels. 2. Innovative design: Coordinated efforts of internal and external power supply A power generation wheel with both internal and external power supply functions has emerged, successfully breaking this predicament. This power generation wheel is mainly composed of tires, connecting shafts, hubs, internal power supply mechanisms and external power supply mechanisms. The internal power supply mechanism is located inside the wheel hub and cooperates with the first magnetic ring on the connecting shaft. When the wheel hub drives the coil assembly of the internal power supply mechanism to rotate, cutting the magnetic field of the first magnetic ring, an electric current can be generated to make the light-emitting tube emit light. The tires are made of transparent plastic material, which enables the light-emitting effect to be presented. The external power supply mechanism is also set on the connecting shaft and is externally fitted with a second magnetic ring. It contains a single-strand coil group, a first metal cutting disc, a second metal cutting disc and a second PCB circuit board. The slices at the edges of the two metal cutting discs are spaced apart from each other, forming a toothed circular ring. When the hub drives the second magnetic ring to rotate, the external power supply mechanism cuts the magnetic field lines to generate current, which is then transmitted to the outside through the power supply lead-out lines. Moreover, the external power supply mechanism is fixed and does not rotate, preventing the power supply lead-out wires from being pulled or twisted. 3. Exquisite construction: Craftsmanship is evident in the details There are still many ingenious designs in the power generation wheel. The first and second magnetic rings are multipolar magnetic rings. By optimizing the relevant parameters of the coil and the magnetic ring, current can be generated even at low rotational speeds. There are two designs for the closed cover inside the wheel hub. The one with the opening facing inward is aesthetically pleasing, while the one with the opening facing outward is convenient for installation. Connect the bearings, bolts, nuts and washers on both sides of the shaft to ensure a stable connection of each component and reduce friction. The anti-slip protrusions on the hub and the cross-section of the connecting shaft have also enhanced the practicality of the generator wheel.   4. Working principle: Electrical energy conversion between rotations The working principle of this power generation wheel is based on the electromagnetic induction phenomenon. When the tires and rims rotate, the internal power supply mechanism will make the light-emitting tubes light up. At the same time, the current generated by the external power supply mechanism is delivered to the outside through the power supply lead-out wires, which can supply power to many devices such as electric lamps, LED light strips, and rechargeable batteries, achieving simultaneous power supply both internally and externally. This power generation wheel with both internal and external power supply functions has successfully solved the problem of single power supply function of traditional power generation wheels through its unique structural design, achieving synchronous operation of internal and external power supply functions. It has brought a new breakthrough to the field of rotating wheel technology and has broad application prospects.

    In the traditional design of luminous wheels, the luminous function mainly relies on the principle of magnetic self-power generation. The light-emitting body, the LED, is fixedly installed inside the wheel hub or the wheel. Although this design achieves a certain luminous effect, it has obvious limitations. Since the light-emitting body is built-in, its style is greatly restricted, and only a few fixed design schemes can be adopted, failing to meet users' needs for personalization and diversification. Moreover, once the light-emitting body is damaged or the user wants to change to a different style of luminous effect, the entire wheel hub or wheel needs to be disassembled and replaced. This complex operation process involves disassembly and reassembly steps, which not only consumes time and energy but also greatly reduces the operational flexibility.       Our patent has made innovative improvements to address the above issues by adding a power external connection interface to the wheel hub. The design of this interface is of great significance because it breaks the shackles of the fixed built-in light-emitting body in traditional luminous wheels. Through this power external connection interface, users can freely replace and install various types of light-emitting bodies according to their own preferences and actual needs. These light-emitting bodies are no longer limited to traditional LEDs and can be diversified products with different colors, shapes, patterns, and luminous effects, such as flashing colored lights, dynamically changing light strips, and luminous decorative parts with special shapes.         The utility model relates to the technical field of rotating wheels, specifically to a luminous wheel with self-power generation function and integrated power external supply interface, which is suitable for various rotating wheel devices such as bicycles, electric vehicles, kid's ride on toys light up wheel, and balance cars that require the wheels to emit light or external electrical equipment to be connected.   ● In the sport of skateboarding, skateboarders who pursue individuality and cool effects can connect the flashing colored lights to this external supply interface. The electric energy generated by the flashing wheels during skateboarding drives the colored lights to flash, which not only provides illumination during skateboarding to ensure the safety of the user but also adds fun to the skateboard and makes the skateboarder the focus on the street at night.   ● In terms of children's toy cars, after installing this luminous wheel, during the child's riding process, the LED light strip on the wheel will flash accordingly, emitting a gorgeous light and adding more fun to the child's playtime. On a scooter light up wheel can also show individuality through different light combinations, attract attention, and become a beautiful scenery on the street at night.         Our patent, through the innovative design of adding a power external connection interface, effectively solves the problems of the single style and inconvenient replacement of the light-emitting elements in traditional luminous wheels. Its core advantage lies in the ability to flexibly select and connect suitable electrical devices to the external supply interface according to diverse needs, providing users with a more flexible, diverse, and convenient user experience, and having broad application prospects and market value.
