Torque sensing device and electric assist bicycle using the torque sensing device

摘要

Embodiments of the present invention have proposed a torque sensing device and an electric assist bicycle used in an electric assist bicycle. The torque sensing device includes a center shaft, a fixed component fixed to the electric assist bicycle, and a rotating component that rotates together with the center shaft of the electric assist bicycle, in which a strain sensor is installed on the rotating component, and When rotating the rotating component, the strain sensor detects the torque of the center shaft, converts the torque into a torque electric signal and outputs the signal, the fixed component includes a fixed component circuit board, and the rotating component rotates. The fixed component circuit board or the rotating component circuit board is provided with a processing unit for receiving and processing the torque electric signal.
