Title:
TORQUE SENSOR SYSTEM, TORQUE SIGNAL MEASURING METHOD, ELECTRIC POWER-ASSISTED BICYCLE
Document Type and Number:
WIPO Patent Application WO/2018/000985
Kind Code:
A1
Abstract:
A torque sensor system, a torque signal measuring method and an electric power-assisted bicycle, related to the technical field of transportation, solving the technical problem of current torque sensor systems generally needing a power input shaft to rotate in order to accurately measure stepping force provided by a rider. The torque sensor system comprises: a planetary gear mechanism (1), the planetary gear mechanism (1) comprising a power input component, a power output component and a torque detecting component; the torque detecting component is provided with an elastomer (2), a torque sensor (3) being provided on the elastomer (2); when external force is input via the planetary gear mechanism (1) power input component and output via the power output component, the reaction force of the output power of the planetary gear mechanism (1) is transferred to the elastomer (2) of the torque detecting component, initiating deformation of the elastomer (2), while the torque sensor (3) obtains the magnitude of input torque by means of measuring the deformation of the elastomer (2).
