Problems solved by technology

[0003] The existing axial torque sensor has certain defects in use. The connector of the sensor is inconvenient to connect with the pedal lever on the electric bicycle, and the connection between the sensor and the pedal lever is not firm enough. The sensor has no protective structure during use, and the sensor is vulnerable to damage. The damage caused by the collision of foreign objects has brought a certain impact on the use process. Therefore, the shaft torque sensor is now improved

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a shaft torque sensor. Background technique [0002] The torque sensor is the detection of torsional torque perception on various rotating or non-rotating mechanical parts. The torque sensor converts the physical change of the torque into an accurate electrical signal. The shaft torque sensor is widely used in electric bicycles. The sensor can be used according to the rider's The pedaling force enables the electric device to provide corresponding power support, thereby reducing the rider's riding burden. [0003] The existing axial torque sensor has certain defects in use. The connector of the sensor is inconvenient to connect with the pedal lever on the electric bicycle, and the connection between the sensor and the pedal lever is not firm enough. The sensor has no protective structure during use, and the sensor is vulnerable to damage. The damage caused by the collision of for...
