Description

Electric bicycle operating device

The invention relates to an electric bicycle operating device.

According to the previous, the traditional bicycles were fully stepped on by human power, driving the chainring to drive the chain to rotate, and the chain then driven the chainring of the rear wheel to rotate the rear wheel forward. In order to increase speed and save effort, the bicycle industry has combined the traditional chainring chain structure. Motors and electric bicycles began to appear, enabling electric bicycles to have both a variable speed function and a motor drive function to change the gear ratio of the chain engagement and motor drive to achieve a labor-saving riding effect, making it easier to ride.

However, when the user is changing the speed while the motor is still actuating, the chain will be subjected to the force of the motor and the tension will be too large, so it is easy to cause the chain to fail to smoothly switch the chainring or the chain breaks. The motor must be stopped first. (For example, let go of the throttle of the handle), the gear can be shifted to ensure a smooth shifting process. However, this process is too cumbersome and generally users often forget to stop the motor first to shift, which causes such problems to occur frequently. The shortcomings of improvement.

Therefore, it is necessary to provide a novel and progressive electric bicycle operating device to solve the above problems.

The main purpose of the present invention is to provide an electric bicycle operating device with a signal transmitter, which will be triggered when the rotating sleeve of the electric bicycle operating device rotates, and the signal transmitter will be transported first An electronic signal for functions such as variable speed, motor power off, or warning light.

To achieve the above object, the present invention provides an electric bicycle operating device, which includes a base, a rotating sleeve and a signal transmitter.
