Title:
PEDALING FORCE DETECTION MECHANISM, DRIVING DEVICE, HUB DEVICE AND POWER-ASSISTED BICYCLE
Document Type and Number:
WIPO Patent Application WO/2021/136524
Kind Code:
A1
Abstract:
Provided are a pedaling force detection mechanism, a driving device, a hub device and a power-assisted bicycle. The pedaling force detection mechanism comprises a toothed disc tower base (110) which can sheathe a mounting shaft (100) and can rotate, wherein spline teeth (210) are arranged on the outer side of the toothed disc tower base (110), a tension detection assembly (300) is packaged in the toothed disc tower base (110), and the tension detection assembly (300) is positioned between the toothed disc tower base (110) and the mounting shaft (100); and after the toothed disc tower base (110) rotates, the tension detection assembly (300) is used for detecting the chain tension driving the toothed disc tower base (110) to rotate, wherein the tension is derived from the stepping force, and the mounting shaft (100) is an axis of a driving electric motor (10) or a hub. According to the technical solution, the pedaling force detection device is arranged at the position of a rear hub and can be disassembled and combined or directly combined with the driving electric motor (10) into a whole, so that a detection device and non-standard fittings on a five-way shaft are omitted, bicycle assembly is more convenient, and costs are saved.
