Description

Electric bicycle operating device

The invention relates to an electric bicycle operating device.

In the past, traditional bicycles were pedaled entirely by humans, driving the chainring to drive the chain to rotate, and then the chain driving the chainring of the rear wheel to rotate to make the rear wheel rotate forward. In order to increase the speed and save effort, the bicycle industry combined the structure of the traditional chainring chain. Motors, electric bicycles began to come out, allowing electric bicycles to have both variable speed and motor drive functions to change the gear ratio of the chain engagement and motor drive to achieve a labor-saving riding effect, making riding more relaxed and comfortable.

However, when the user is shifting the speed while the motor is still in motion, the chain will be stressed by the motor, resulting in excessive tension. This will easily cause the chain to fail to switch the chainring smoothly or the chain to break. The motor must be stopped first. (Such as loosening the throttle of the handle), you can shift to ensure a smooth shifting process. However, this process is too troublesome and users often forget to stop the motor first and then shift. This causes such problems often to occur, and there is an urgent need The shortcomings of improvement.

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

The main purpose of the present invention is to provide an electric bicycle operating device, the electric bicycle operating device has a signal transmitter, when the rotating sleeve of the electric bicycle operating device rotates, the signal transmitter will be triggered, and the signal transmitter will transmit first An electronic signal for functions such as speed change, motor cut-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. The seat body is for sleeved on the handle of an electric bicycle and defines an axis. The rotating sleeve can be sleeved on the seat body to rotate along the axial direction, and can be displaced along the axial direction relative to the seat body, and is provided with a first clamping part. The signal transmitter is arranged on one of the base and the rotating sleeve, and is provided with a sensing device that can rotate and move along the axis relative to the signal transmitter, and the sensing device is additionally provided with a second Two card parts, the first card part is engaged with the second card part.
