Abstract

The invention provides a power-assisted sensor, which is applied to a device adopting chain transmission, and comprises a tension acquisition assembly for acquiring the tension degree of a chain, a force application state of the chain acquired by the tension acquisition assembly, and a rotating speed acquisition assembly for acquiring the rotating speed of the chain, the device judges whether assistance is needed or not and judges the assistance percentage through the tensioning acquisition assembly and the rotating speed acquisition assembly. According to the power-assisted sensor, by collecting the rotating speed of a flywheel and combining the deformation quantity of a cross arm, the current advancing state of the chain is known, and whether power assistance is needed or not is judged.

Description

technical field [0001] The invention belongs to the technical field of chain transmission, and in particular relates to a power assist sensor and a bicycle. Background technique [0002] At present, the speed-type power sensor on the market generally adopts the method of double Hall and disk to detect the rotation of the crank. This solution does not consider the problem of crank rotation during implementation. Increasing or decreasing the power assist can not provide a good riding experience; the torque sensor can avoid the above problems, but the structure is complex and the cost is too high; the invention effectively solves the problem of follow-up, downwind and headwind, uphill and downhill, etc. problem, and avoid the cost of the torque sensor. Contents of the invention [0003] In view of this, in order to overcome the above-mentioned defects, the present invention aims to provide a power-assisted sensor and a bicycle to solve problems such as crank rotation, downwi...
