The invention provides a pedaling force detection mechanism of an electric auxiliary bicycle. The pedaling force detection mechanism comprises a pedaling force steering part, a main thrust bearing, a strain sensing assembly and a main transmission gear. The treading force steering part unidirectionally drives the treading force of the crankshaft and the steering treading force to face the axial direction of the crankshaft; the main thrust bearing abuts against the outside of the treading force steering part so as to transmit the steered treading force. The strain sensing assembly is provided with a strain gauge, an elastic annular seat body and a supporting annular seat body, the supporting annular seat body abuts against the axle box, an axial strain gap is formed between the supporting annular seat body and the main thrust bearing, and the elastic annular seat body is arranged outside the supporting annular seat body and abuts against the position between the main thrust bearing and the supporting annular seat body; an inner connecting ring body of the main transmission gear and the main gear are integrally formed, and an axial moving gap is formed between the treading force steering part and the inner connecting ring body. The pedaling force detection mechanism of the electric auxiliary bicycle achieves the purpose of fully reflecting the change of pedaling force so as to provide auxiliary power.

    本发明提供一种电动辅助自行车的踩踏力侦测机构,其包含踩踏力转向部、主止推轴承、应变感测组件及主传动齿轮。踩踏力转向部单向传动曲柄轴的踩踏力及转向踩踏力朝向曲柄轴的轴向;主止推轴承抵靠于踩踏力转向部外以传递转向后的踩踏力;应变感测组件具有应变规、弹性环型座体及支撑环型座体,支撑环型座体抵靠于轴箱且与主止推轴承之间具有轴向应变间隙,弹性环型座体设于支撑环型座体外且抵靠于主止推轴承与支撑环型座体之间;主传动齿轮的内连接环体与主齿轮为一体成型,踩踏力转向部与内连接环体之间具有轴向活动间隙。本发明的电动辅助自行车的踩踏力侦测机构达到了可充分反应踩踏力的变化以提供辅助动力的目的。
