[0023] Please refer to Figure 1-Figure 4 , the present utility model provides two technical solutions, specifically including the following embodiments:
[0024] Embodiment 1:
[0025] A power generation hub includes a hub shell 5. Inside the hub shell 5, a hub core 4, a strong magnetic rotor 1, stator silicon steel sheets 2, enameled wires 3, a limiting strip 6, and an outer bearing 7 are respectively installed. The stator silicon steel sheets 2 are installed on the hub core 4. The setting of the hub core 4 makes the internal structure of the power generation hub more compact, improving the stability and reliability of the power generation hub. The enameled wires 3 are wound around the surface of the stator silicon steel sheets 2. The winding setting of the enameled wires 3 makes the power generation efficiency of the power generation hub higher and the output voltage more stable. The enameled wires 3 and the stator silicon steel sheets 2 form an integral structure. The formation of the integral structure improves the mechanical strength and durability of the power generation hub. Outer bearings 7 are installed at both ends inside the hub shell 5 through the limiting strip 6. The setting of the outer bearings 7 ensures that the power generation hub rotates more smoothly, reduces frictional losses, and improves the power generation efficiency. The hub core 4 is installed in the middle part inside the hub shell 5. The strong magnetic rotor 1 rotates coaxially with the hub core 4. The setting of the strong magnetic rotor 1 makes the power generation efficiency of the power generation hub higher and the output power greater. A end cover 8 is installed at one end of the surface of the hub shell 5. The setting of the end cover 8 protects the internal structure of the power generation hub, prevents dust and foreign objects from entering, and improves the reliability of the power generation hub. A sleeve 9 is installed at the other end of the surface of the hub shell 5. A number of mounting holes 10 are penetrated through the surface of the sleeve 9. The setting of the mounting holes 10 facilitates the user to fix the power generation hub on the axle or other devices, improving the applicability of the power generation hub.
[0026] When using this power generation hub, the cyclist places the bicycle in a normal riding state. As the wheel rotates, the strong magnetic rotor 1 also rotates accordingly, and the magnetic field it generates continuously cuts the enameled wire turns on the stator silicon steel sheets 2. According to the electromagnetic induction principle, an induced current will be generated in the coil. The user can choose to store the direct current in the battery or directly supply power to the lighting device, navigation device, or other electronic devices on the bicycle as needed. In addition, the user can also install a lighting device on the hub shell 5 or other parts of the bicycle and use the current generated by the power generation hub for lighting to enhance the safety of night riding. During the riding process, the interaction between the strong magnetic rotor 1 and the stator silicon steel sheets 2 continuously generates current, realizing the recycling of energy, which not only provides convenience for the cyclist but also reflects the concept of energy conservation and environmental protection.
[0027] Embodiment Two:
[0028] On the basis of the first embodiment, mounting blocks 11 are fixedly connected to both ends of the outer surface of the hub shell 5. A plurality of spoke holes 12 are formed through the surface of the mounting block 11. This design enables the generator hub to be directly connected to the bicycle rim. The provision of the spoke holes 12 facilitates the installation of the spokes and enhances the stability of the structure. The strong magnetic rotor 1 is installed on the inner surface of the hub shell 5, and the stator silicon steel sheet 2 is installed on the outer surface of the core 4. This layout optimizes the distribution of magnetic lines of force, improves the power generation efficiency, and facilitates maintenance and replacement of parts. An inner bearing 13 is also installed on the inner side of the hub shell 5. The setting of the inner bearing 13 further improves the stability of the rotating parts, reduces friction, and extends the service life. The installation position of the strong magnetic rotor 1 and the stator silicon steel sheet 2 is not limited to the center of the hub shell 5, but can also be placed in any other place of the hub shell 5. This flexible installation position design allows the power generation hub to be customized according to different application requirements, thereby improving the applicability of the product. A light-emitting device is installed on the outer surface of the hub shell 5. The light-emitting device is installed on the hub shell 5 or other components. The addition of the light-emitting device not only increases the safety of night riding, but also improves the aesthetics and fun of the product.
[0029] When riding, the strong magnetic rotor 1 generates a magnetic field as the wheel rotates, and the three turns of enameled wire on the stator silicon steel sheet 2 cut the magnetic field lines to generate alternating current. Users can choose to store the direct current in a battery or directly power bicycle lighting, navigation equipment, or other electronic devices as needed. In addition, users can also install a light-emitting device, such as a lamp, on the hub shell 5 or other parts of the bicycle, and use the current generated by the generating hub to provide lighting for the bicycle at night, improving riding safety. During riding, the interaction between the strong magnetic rotor 1 and the stator silicon steel sheet 2 continuously generates current, realizing the recycling of energy. This not only provides convenience for the rider, but also embodies the concept of energy conservation and environmental protection.
[0030] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
