Abstract

The invention discloses an integrated device for friction power generation and braking of a bicycle, belongs to a brake technology of bicycles and particularly belongs to a technology of bicycle brake and power generation using brake friction forces. According to the device, an external rotating type generator is arranged at a hollow position at an opening end of a concave fixing frame, an internal stator of the external rotating type generator is fixedly connected with the opening end of the concave fixing frame, an external rotor of the external rotating type generator is located at a position close to a bicycle tyre, the side wall of the concave fixing frame is slidingly connected with a frame of the bicycle, and an elastic braking device is fixed at a bottom edge of the concave fixingframe. The device has the advantages that one set of devices are used for achieving speed reduction, braking and power generation, and energy which is used for achieving speed reduction and braking of the bicycle is converted into electric energy for recycling.

Description

technical field [0001] The invention belongs to the braking technology of bicycles, in particular to the technology of combining bicycle braking with braking friction to generate electricity. Background technique [0002] The braking of existing bicycles and the use of wheel friction to generate electricity are realized by two different devices. The shortcoming is that the braking energy cannot be used to generate electricity, but electricity is generated during normal driving. When driving normally, the power generation generates resistance to the wheels, which increases the effort of people stepping on the bicycle. Contents of the invention [0003] The purpose of the present invention is to provide a bicycle that can recover the braking energy of the bicycle and utilize the braking friction to generate electricity. [0004] Structure of the present invention is: [0005] An integrated device for bicycle friction power generation and braking, including an inner stator ...
