Electronic speed change controller, speed change system and bicycle

Abstract

The invention provides an electronic speed change controller, a speed change system and a bicycle. The electronic speed change controller comprises a base provided with a first rotating shaft, a brakerod rotationally installed on the first rotating shaft and a control unit. The control unit comprises a rotating rod rotatably mounted on the first rotating shaft or a second rotating shaft and an operating rod mounted on the rotating rod; a first switch element and a second switch element are arranged on the rotating rod; the operating rod is provided with a first pressing part and a second pressing part; in the braking direction of the brake rod, the first switch element is located between the brake rod and the second switch element, the first pressing part is located between the brake rodand the second pressing part, and in the axial direction of the first rotating shaft, the first pressing part can move to abut against the first switch element, and the second pressing part can move to abut against the second switch element. The speed change system is provided with the electronic speed change controller, a bicycle is provided with the electronic speed change controller or the speed change system, and the electronic speed change controller has the advantages of being easy to operate and reasonable in structural layout.

Description

technical field [0001] The present invention relates to the technical field of bicycle speed change, in particular to an electronic speed change controller, a speed change system provided with the electronic speed change controller, a bicycle, and a bicycle provided with the above speed change system. Background technique [0002] With the development of the bicycle industry, the bicycle transmission system has derived an electronic transmission system on the basis of the traditional mechanical transmission system, and with the gradual maturity of the electronic transmission system technology, the electronic transmission system has been widely used in recent years. sought after. Compared with the mechanical transmission system, the operation of the electronic transmission system is more stable and the operation is more convenient, and for the transmission controller in the transmission system, the structure of the electronic transmission controller is much simpler than that ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing electronic shifting controller has the following disadvantages: the position layout of the shift lever and the shift lever used to control the electronic derailleur is unreasonable, which makes the shifting and shifting operation of the electronic shifting system cumbersome and error-prone

In addition, only one gear lever is set on some existing electronic transmission controllers, so that when controlling the front electronic derailleur and / or the rear electronic derailleur, it is necessary to control the gear position of the left electronic transmission controller. The front electronic derailleur and / or the rear electronic derailleur can perform corresponding gear shifting actions only when the joystick and the gear position joystick of the right electronic shift controller are logically controlled
