The rotating shaft of the roller is rotationally connected. When the brake decelerates, the roller is pressed against the rear wheel of the bicycle under the pulling of the brake line. The rear wheel still maintains deceleration rotation when braking, so it can drive the roller to rotate under the action of friction. The roller drives the input shaft of the generator to rotate through the transmission gear set to realize power generation. Finally, the electrical energy is stored in the energy storage power bank. The utility model does not need complex installation environment, and the structure is simple and has strong universality. At the same time, the roller presses against the rear wheel, which also has a certain braking effect, reduces the burden of the brake device, improves the service life of the brake device, and is more economical to use.

The transmission of kinetic energy is realized. This way has a simple structure, and the production personnel can also change the number of teeth to improve the transmission ratio between the gears and improve the working efficiency of the generator. The number of teeth of the second straight gear is greater than that of the first straight gear, which can increase the transmission ratio between the gears and improve the power generation efficiency of the generator. Through the arc-shaped slide rail, it can ensure that the first straight gear and the second straight gear are always in a coupled state. Even if the second straight gear moves with the roller on the support, the first straight gear and the second straight gear will not be decoupled, avoiding misalignment friction between the gears, causing part damage, and improving the service life of the device. The reset spring can drive the roller to reset, avoiding the situation that the gears cannot reset after pulling the brake line and are always pressed against the rear wheel, causing the user to pedal hard.
