AI Technical Summary

Technical Problem

In the prior art, the design of the motor and battery in the hub causes the overall volume of the wheel hub to be too large, heavier, and unstable center of gravity. The battery and motor will affect each other during operation, increasing the risk of damage or failure.

Method used

A bicycle hub assembly is designed, in which no battery assembly is provided in the housing, but a sliding ring is added to the wheel shaft, and the circuit on the control board is directed out of the housing to the outside of the housing and connected to the external power cord. The battery is fixed to the frame to avoid the installation of a battery inside the wheel hub.

Benefits of technology

The overall structure of the bicycle wheel hub assembly is achieved by a more compact and lighter weight, keeping the overall center of gravity of the bicycle stable, avoiding the mutual influence of the battery and the motor during operation, improving the stability of the system, and increasing the flexibility of battery capacity.
