Description

Electronic speed change controller, speed change system and bicycle

Technical Field

The invention relates to the technical field of bicycles, in particular to an electronic speed change controller, a speed change system with the electronic speed change controller and a bicycle.

Background

With the development of the bicycle industry, an electronic speed changing system is derived from a bicycle speed changing system on the basis of a traditional mechanical speed changing system, and with the gradual maturity of the technology of the electronic speed changing system, the electronic speed changing system is widely pursued in recent years. Compared with a mechanical speed change system, the electronic speed change system is more convenient to operate and can realize stable operation. Furthermore, the structure of the electronic shift controller is much simpler than that of the mechanical shift controller for the shift controller in the shift system; for example, the electronic speed change controller mainly shifts the chain to switch the positions by the electronic derailleur through the matching between the electronic components on the electronic speed change controller and the electronic components on the electronic derailleur, so as to realize speed change; the mechanical speed-changing controller needs to make the wire spool drag the speed-changing wire through the complex linkage coordination among the parts such as gears, pawls and the like in the mechanical speed-changing controller, so that the speed-changing wire drives the mechanical derailleur to shift the chain to realize speed change. It can be seen that when the number of switchable gears of the mechanical speed-change controller is larger, the structure is more complicated, the reliability is lower, and the speed-change cable is easy to fatigue and break after being repeatedly wound and released, while the electronic speed-change controller does not have the above problems, and the corresponding speed of the electronic speed-change controller to the operation of the rider is faster.

However, the existing electronic shift controllers have the following disadvantages: the position of the forward and reverse levers used to control the electronic derailleur is not properly arranged, e.g., the forward and reverse levers are too close together to allow for easy control of the wrong lever during operation, resulting in an actual shift result that is opposite to the intended shift result; in addition, if the rider does not often place fingers on the corresponding operating levers of the electronic speed change controller in the riding process, when gear shifting and speed changing operations are required, the rider can accurately operate the operating levers to be controlled only after searching the positions of the corresponding operating levers through the fingers, and the rider feels poor in experience; moreover, only one shift lever is disposed on the existing part of the electronic shift controller, so that when the front electronic derailleur and/or the rear electronic derailleur are/is controlled, the shift lever of the left electronic shift controller and the shift lever of the right electronic shift controller need to be logically controlled to enable the front electronic derailleur and/or the rear electronic derailleur to perform corresponding shifting and shifting actions, and therefore, the operation is troublesome and is prone to errors.
