Electronic variable speed controller, variable speed system and bicycle

Abstract

The invention provides an electronic variable speed controller, a variable speed system and a bicycle. The electronic variable speed controller comprises a mounting seat, a control unit, a lever, a shifting button and a reset elastic piece group, the control unit is mounted in the mounting seat and is provided with a first switch element and a second switch element, and the lever is rotatably mounted in the mounting seat around a first rotating axis; the lever can rotate around the first rotating axis to be in contact with the first switch element and can also rotate around the first rotating axis to be in contact with the second switch element, the shifting button is rotatably mounted on the mounting seat around a second rotating axis, the shifting button is provided with an operating part and a shifting part, and the shifting part is adjacent to the lever and can drive the lever to rotate around the first rotating axis; and the reset elastic piece group forces the shifting button to rotate around the second rotating axis to a preset initial position. The variable speed systemand the bicycle are both provided with the electronic variable speed controller; and the electronic variable speed controller has the advantages of being accurate, convenient and reliable in control and simple in structure.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to an electronic speed change controller, a speed change system provided with the electronic speed change controller, and a bicycle. 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 convenient and can realize stable operation. In addition, for the variable speed controller in the transmission system, the structure of the electronic variable speed controller is much simpler than that of the mechanical variable speed controller; The electronic ...

Problems solved by technology

[0003] However, the existing electronic transmission controller has the following disadvantages: the position layout of the shift lever and the shift lever used to control the electronic derailleur is unreasonable, for example, the shift lever and the shift lever are too close, It makes it easy to control the wrong joystick during the operation, causing the actual shift result to be opposite to the expected shift result; in addition, if the rider does not often place his finger on the corresponding joystick of the electronic transmission controller during riding, then when necessary When performing gear shifting operations, the rider needs to find the position of the corresponding joystick with his fingers before he can accurately operate the joystick he wants to control, resulting in a poor experience for the rider; moreover, some of the existing electronic shift control Only one gear lever is set on the derailleur, so that when controlling the front electronic derailleur and / or the rear electronic derailleur, it is necessary to control the gear lever of the left electronic shift controller and the gear lever of the right electronic shift controller. Only when the gear lever is logically controlled can the front electronic derailleur and / or the rear electronic derailleur perform the corresponding gear shifting action, so the operation is cumbersome and error-prone
