The invention relates to a dynamic and static combined torque sensor of an electric power-assisted bicycle. The torque sensor comprises an action unit, a detection unit and a processing and outputtingunit, the detection unit detects the magnetic conversion on the action unit and the rotating speed and the rotating direction of the action unit; the processing and outputting unit collects information detected by the detection unit, converts the information into a corresponding voltage signal, performing amplifying processing and outputting the amplified signal, the output signal of the processing and outputting unit is output through a filter cable, the peripheries of the detection unit and the processing and outputting unit are sleeved with a metal sleeve, a groove is formed in the inner periphery of the metal sleeve and parallel to the axis of the metal sleeve, and a protrusion is arranged at the position, corresponding to the groove, of the filter cable. The invention aims to overcome the defects in the prior art. The dynamic and static combined torque sensor of the electric power-assisted bicycle is good in measurement precision, high in universality and stable in internal signal output.

    本发明涉及一种电动助力自行车动静态结合的力矩传感器,包括动作单元、检测单元和处理输出单元,检测单元检测动作单元上磁性的转变以及动作单元的转速和转向,处理输出单元采集检测单元检测到的信息,并将其转换成相应的电压信号,经处理放大输出,处理输出单元的输出信号经滤波电缆输出,检测单元和处理输出单元外周套设有金属套,金属套的内周设有凹槽,凹槽与金属套的轴心平行设置,滤波电缆上与凹槽对应的位置处设有凸起。本发明的目的是克服现有技术存在的缺陷,提供一种测量精度好,通用性强以及内部信号输出稳定的动静态结合的电动助力自行车力矩传感器。
