Problems solved by technology

Some electric bicycles have strain gauges on the body to transmit the sensing signal to the controller, but the power provided by the rider to the bicycle cannot be accurately calculated from the torque on the body
In addition, in some electric assist bicycles, the strain gauge is arranged on the center shaft directly driven by the pedal and the crank, and then the sensing signal sent by the strain gauge is transmitted to the controller through a sensor arranged on the vehicle body; As a result, the power prov

Abstract

The invention discloses a torque sensing system for bottom brackets of bicycles, which comprises a torque sensor, a wireless signal transmitter and a wireless signal receiver, wherein the torque sensor is arranged at a bottom bracket for bicycles, and the wireless signal transmitter and the bottom bracket are relatively fixed; the wireless signal receiver is arranged at a fixed position (near the bottom bracket) of a bicycle body, and the wireless signal transmitter is used for receiving sensing signals transmitted by the torque sensor, and then sending the sensing signals to the wireless signal receiver in a non-contact mode, so that the sensing signals are difficult to attenuate or lose in the process of transmission, therefore, torques provided for a bicycle by a rider can be sensed accurately.

Description

technical field [0001] The invention relates to a sensing system for the torque of a bicycle, in particular to a torque sensing system for a bicycle center shaft and a quadratic signal transmission method thereof. Background technique [0002] Existing electric mopeds, also known as electric power-assisted bicycles, use electric power to assist manpower to provide the kinetic energy required for the bicycle to travel. Therefore, the bicycle will have a torque sensing system that uses a strain gauge to sense the force on the bicycle. The torque is used for a controller to judge whether the power provided by the rider is sufficient. Some electric-assist bicycles have strain gages arranged on the body so as to transmit sensing signals to the controller, but the power provided by the rider to the bicycle cannot be accurately calculated from the torque on the body. In addition, in some electric assist bicycles, the strain gauge is arranged on the center shaft directly driven by ...
