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.
