The invention provides a power output mechanism of an electric power-assisted bicycle, and relates to the technical field of electric power-assisted bicycles. The assistance output mechanism based on the electric assistance bicycle comprises a connecting base, a driving base and a transmission base, the driving base is fixedly connected to one side of the upper portion of the connecting base, the transmission base is fixedly connected to the side, away from the driving base, of one end of the upper portion of the connecting base, and an assistance motor is fixedly connected to the side, away from the driving base, of the upper portion of the connecting base; a sliding groove is formed in the connecting base. The connecting base is provided with the sliding groove and the corresponding sliding block, so that the rotating shaft can linearly move, the linear Hall element and the return spring are matched, the linear Hall element can be driven to control the power of the motor through chain tightening tension generated by the difference between treading force and vehicle resistance in the treading process, the assisting power of the assisting motor is made to fluctuate smoothly, and the service life of the assisting motor is prolonged. And it is guaranteed that the legs can exert force all the time, the light and heavy state is avoided, and the riding experience is improved.

    本发明提供电助力自行车的助力输出机构,涉及电助力自行车技术领域。该基于电助力自行车的助力输出机构,包括连接座、驱动座和传动座,所述连接座的上方一侧固定连接有驱动座,所述连接座的上方一端远离驱动座的一侧固定连接有传动座,所述连接座的上方远离驱动座的一侧固定连接有助力电机,所述连接座的内部开设有滑槽。本发明的连接座设置有滑槽和相对应的滑块,使转动轴可线型运动,配合直线型霍尔元件和回位弹簧,可通过踩踏时,由于踩踏力和车辆阻力差产生的链条绷紧张力,驱动直线型霍尔元件控制电机功率,使助力电机的助力波动顺滑,保证腿部一直能够发力,避免出现一下轻一下重的状态,提高骑行体验。
