Bicycle control device

Abstract

The invention relates to a bicycle control device. The bicycle control device comprises a lifting control device body, a rear speed changing control device body, a lifting seat pipe, an electric reartransmission and a seat pipe controller. The lifting control device body is used for generating and transmitting a lifting control signal. The rear speed changing control device body is used for generating and transmitting a speed changing control signal. The lifting seat pipe is disposed in a vertical pipe and can be controlled to ascend and descend or locked in height. The seat pipe controller is fixedly disposed on the vertical pipe of a bicycle and provided with a wireless signal receiver, a control circuit and a motor; the wireless signal receiver is used for receiving and transmitting alifting or speed changing control signal to a control circuit; the control circuit is electrically connected to the electric rear transmission and the motor and used for controlling the motor or the electric rear transmission to move according to the received lifting or speed changing control signal, and when the motor is moved, the lifting seat pipe can be controlled to ascend and descend or locked in height by a mechanically driven structure.

Description

technical field [0001] The present invention is related to bicycles; in particular, it refers to a bicycle control device that can provide the rider with variable speed and seat lift control. Background technique [0002] In recent years, with people's emphasis on environmental protection and the government's implementation of energy conservation and carbon reduction, bicycle riding has become popular again. In order to improve the mobility, convenience and practicality of bicycle riding, various manufacturers gradually The development of related equipment such as electric variable speed control and real-time control of seat lifts can be installed on the bicycle by the rider, so that the rider can directly use the hand to control the relevant control device when riding the bicycle, which can be accurate and accurate. Quickly achieve the purpose of speed change and center of gravity adjustment. [0003] However, although the above-mentioned equipment can achieve the purpose ...

AI Technical Summary

Problems solved by technology

Yet when installing this type of electronic transmission for some bicycles that only need a single front gear (such as a mountain bike), even if the front shifting function is not required, the front derailleur still needs to be installed to control the rear derailleur. This will not only cause additional load Increased weight, more likely to increase additional maintenance costs

[0005] Therefore, it can be seen from the above description that the control design of the existing dropper seat tube and electronic transmission is still not perfect, and there is room for improvement
