The invention discloses a power-assisted sensor of an electric bicycle in the technical field of sensors, and the power-assisted sensor comprises a conduction assembly, a conversion assembly and a contact assembly, the conduction assembly is provided with the conversion assembly, the conduction assembly is used for conducting pressure deformation, the conversion assembly converts the deformation quantity of the conduction assembly into an electric signal, and the electric signal is transmitted to the contact assembly. The free end of the conduction assembly is connected with a contact assembly. According to the support, the swing arm is movably installed through the rotating shaft, the contact assembly at one end of the swing arm is in contact connection with the chain, the arc-shaped face of the guide block in the contact assembly makes contact with the chain, the friction force is reduced through the arc-shaped connecting face, and the long and wide guide block can make contact with the chain in the transverse wide range; when the multistage variable-speed chain wheel of the bicycle chain is changed and shifted, the chain is in close contact during transverse movement, tension is better transmitted, meanwhile, the chain is prevented from being separated from the guide block, and the chain is more smoothly in contact with the guide block and is not prone to being clamped.
本发明公开了传感器技术领域的一种电动自行车的助力传感器,包括传导组件、转化组件和接触组件,所述传导组件上安装有转化组件,所述传导组件用于传导压力形变,所述转化组件将传导组件的形变量转化为电信号,所述传导组件的自由端连接有接触组件。本发明支架通过转轴进行摆臂的活动安装,摆臂的一端的接触组件与链条接触连接,接触组件中的引导块的弧形面与链条接触,弧形的连接面减少摩擦力,长宽的引导块可在横向宽范围上与链条接触,在自行车链条多级变速牙盘变换挡位时,链条横向移动时进行紧密接触,更好的传递张力,同时避免链条与引导块的脱离,链条更加顺滑的与引导块接触,不容易卡住。
