Abstract

The invention provides a power-assisted bicycle and its speed change device; wherein, the speed change device includes 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 to provide electric energy; the sensing unit is used to collect Motion signal; the motion signal includes cadence signal and torque signal; the electronic control unit is used to output gear information to the transmission unit according to the motion signal and the user's preset motion mode, so as to adjust the gear position of the transmission unit and output power assistance to the motor unit information to adjust the output power of the motor unit. The present invention can adjust the speed and assist of the bicycle according to the exercise mode set by the user, so as to meet various riding demands of the user in different road environments, and improve the riding experience of the user.

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...
