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.
本发明创造提供了一种助力传感器,应用于采用链条传动的装置,包括:用于采集链条张紧程度的张紧采集组件,通过所述张紧采集组件采集链条的施力状态,用于采集链条转速的转速采集组件;装置通过所述张紧采集组件和所述转速采集组件判断是否需要助力,及助力百分比。本发明创造所述的助力传感器通过采集飞轮的转速结合横臂的形变量,了解目前的链条的行进状态,判断是否需要助力。
