Description

Technical Field

[0001] The utility model relates to the field of electric power-assisted bicycles, in particular to a connection structure of an internal wiring group of an electric power-assisted bicycle. Background Art

[0002] Electric-assisted bicycles are different from ordinary bicycles in that they use electric motors as auxiliary power output sources to provide power assistance when the rider is riding. This is also different from ordinary electric bicycles, which use electric motors as the complete power output source and use pedals as alternative power when power is insufficient. Therefore, electric-assisted bicycles are more like an upgrade of traditional bicycles.

[0003] Since the motor is used as auxiliary power, the body needs to be equipped with batteries, motors, sensors and some supporting electronic components, so it involves the need to use transmission lines for connection. Traditional bicycles also have existing lines such as brake lines and transmission lines. As a result, there are many fixed lines on the body of the electric-assisted bicycle, which looks very messy and will increase the wind resistance when riding. Therefore, a better solution is needed to solve the problem of wiring of electric-assisted bicycles.

[0004] In addition, in order to meet the riding needs of riding users, it is necessary to convert between electric-assisted bicycles and ordinary bicycles. Therefore, there is also a need for a solution to solve the problem of easily converting electric-assisted bicycles into ordinary bicycles, or converting ordinary bicycles into electric-assisted bicycles.
