Booster bicycle and speed change device thereof

Abstract

The invention provides a booster bicycle and a speed change device thereof. The speed change device comprises an electronic control unit, a power supply unit, a motor unit, a speed change unit and a sensing unit. The power supply unit is used for providing electric energy. The sensing unit is used for acquiring movement signals of the bicycle. The movement signals comprise treading frequency signals and torque signals. The electronic control unit is used for outputting gear information to the speed change unit according to the movement signals and a movement mode preset by a user in order to adjust gears of the speed change unit, and outputting boosting information to the motor unit in order to adjust the output power of the motor unit. The speed and assistance of the bicycle can be adjusted according to the movement mode set by the user, multiple riding requirements of the user in different road environments are met, and the riding experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of electric bicycles, in particular to an assist bicycle and a transmission device thereof. Background technique [0002] At present, people are more and more fond of choosing bicycles for travel, which can not only exercise but also save energy and reduce carbon emissions. However, for long-distance riding, purely mechanical bicycles have higher requirements for people's time cost and physical fitness; power-assisted bicycles can effectively reduce the requirements for riders' physical fitness, reduce physical exertion, and increase cycling. distance and speed; however, the existing power-assisted bicycles have a single speed and power distribution method, and have low adaptability to complex traffic and different road conditions in various places. In many cases, it is difficult to meet the actual riding needs of users. Contents of the invention [0003] In view of this, the object of the present inventi...

Problems solved by technology

However, for long-distance riding, purely mechanical bicycles have higher requirements for people's time cost and physical fitness; power-assisted bicycles can effectively reduce the requirements for riders' physical fitness, reduce physical exertion, and increase cycling. distance and speed; however, the existing power-assisted bicycles have relatively simple speed and power distribution methods, and have low adaptability to complex traffic and different road conditions in various places. In many cases, it is difficult to meet the actual riding needs of users
