Document Type and Number:
WIPO Patent Application WO/2021/063019
Kind Code:
A1
Abstract:
A torque sensor for a power-assisted bicycle, and a power-assisted bicycle. The torque sensor for a power-assisted bicycle comprises a central shaft (1), a strain detection unit (2) provided on the central shaft (1), an induction coil (3) and a signal processing unit (4) electrically connected to the induction coil (3). The induction coil is arranged at the periphery of the strain detection unit. The strain detection unit comprises a plurality of strain detection strips (21) uniformly applied to an outer wall of the central shaft in a circumferential direction thereof. Two ends of each strain detection strip are free ends. The torque sensor for a power-assisted bicycle improves the stability of the strain detection unit installed on the central shaft, and increases the sensitivity of the strain detection unit to a magnetic permeability change under the action of torque.
