Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of bicycle manufacturing, and particularly relates to a bicycle hub supporting a TYPE-C charging interface and an application method thereof. BACKGROUND

[0002] In the field of bicycle parts technology, the hub is a core component for connecting spokes and a frame, and its performance directly affects the stability, safety and functionality of riding. With the diversification of riding needs, users have higher requirements for the integrated functions of the hub. Not only does it need to meet the basic transmission needs, but it also expects to have additional functions such as charging and emergency inflation. Traditional bicycle hubs focus on optimizing mechanical transmission performance and have relatively single functions, which are difficult to adapt to the complex needs of modern riding scenarios.

[0003] In the prior art, some bicycle hubs integrated with charging functions use a dedicated charging interface, which has poor compatibility and cannot adapt to mainstream TYPE-C charging devices, causing inconvenience to users. A few hub products integrated with air pumps have a fixed connection method between the air pump and the hub transmission structure, lack a flexible torque adjustment mechanism, and cause the air pump to start at an inappropriate time and not match the riding state. In addition, the existing hub shells are mostly made of aluminum alloy, which has limitations in balancing lightweight and structural strength. Furthermore, in terms of power supply stability, the existing hubs with batteries lack dynamic power management for different battery states, which can easily cause excessive voltage fluctuations when the air pump is working, affecting the safety of the charging interface and the cycle life of the battery.
