Abstract

The invention discloses an electric power device of a bicycle. The electric power device of the bicycle mainly solves the problems that an existing lithium battery moped is difficult to ride, heavy in weight and complex in control circuit. The power device comprises a motor arranged on a bicycle body, a lithium battery pack for providing electric energy for the motor, a motor drive control system for controlling the motor running, a gearbox connected with the motor, and a center shaft device connected with the gearbox through an auxiliary chain, wherein the center shaft device is connected with a chain plate. The electric power device of the bicycle uses low-power consumption and modular design, the weight is light, the mounting and maintaining are simplified, the structure of an original bicycle is not changed, the riding experience is not influenced, the output power of the motor can be controlled according to different proportions, both the high-speed riding and low-speed riding can obtain the electric power effect, the electric energy waste is avoided, and the pure electric drive mode, pure manpower drive mode, and electric and manpower hybrid drive mode are realized; the three running modes perfectly combine manpower and electricity, and the electric power device of the bicycle can serve as an ideal tool for urban riding and riding training.

Description

technical field [0001] The invention relates to an electric power booster for a bicycle, which belongs to the field of leisure sports riding equipment. Background technique [0002] At present, the known electric power-assisted bicycle is made up of lithium battery pack and motor controller, and the weight adds up to about 7 kilograms, and the lead-acid battery is heavier. Most of the motors are directly installed in the wheels and directly drive the wheels to move. Due to the structure of the motors, the manufacturer has adjusted the speed of the motors at the factory. When the speed of riding exceeds the speed of the motors, the motors can no longer play a role in assisting. , and the faster it is, the less power-assisted effect it will consume power, and because the size of the motor does not match the structure of the bicycle, it will bring a lot of negative effects after installation, so it feels particularly strenuous when riding at high speed, and the speed cannot be...
