Abstract
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.
