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.
