The invention relates to the field of electric vehicle accessories, in particular to a power-off safety device for a brake handle of an electric vehicle, which comprises a master cylinder and a brake handle structure, a disc piston body arranged in a master cylinder body of the master cylinder is sleeved with a magnetic part, and a magnetic reed switch assembly is hung at the position, corresponding to the magnetic part, of the outer side of the master cylinder body. The magnetic reed switch assembly is electrically connected with a motor control circuit; the disc piston body is driven by a brake handle structure hinged to a master cylinder body to move, and the disc piston body moves to change the intensity of magnetic force between the magnetic part and the magnetic reed switch assembly, so that the magnetic reed switch assembly feeds back a control signal to a motor control circuit. The power-off safety device for the brake handle of the electric vehicle has the beneficial effects that the magnetic reed switch assembly is hung on the outer side of the cylinder body of the master pump, modular installation of the magnetic reed switch assembly is achieved, a magnetic reed pipe of the magnetic reed switch assembly is effectively protected, the installation space of the master pump does not need to be occupied, the refitting procedure of the electric vehicle brake handle power-off safety device is reduced, and popularization is facilitated.
本发明涉及电动车配件领域,具体是一种电动车刹把断电安全装置,包括总泵和刹把结构,所述总泵的总泵缸体内置的碟活塞本体上套设有磁性件,且总泵缸体外侧与磁性件相对应位置挂装有一磁簧开关组件,所述磁簧开关组件电性连接电机控制线路;所述碟活塞本体受铰接在总泵缸体上的刹把结构驱动而运动,碟活塞本体运动改变磁性件与磁簧开关组件之间的磁力强度,以使磁簧开关组件向电机控制线路反馈控制信号。本发明的有益效果是:通过在总泵缸体外侧挂装磁簧开关组件,实现了磁簧开关组件的模块化安装,对磁簧开关组件的磁簧管进行有效的保护,无需占用总泵的安装空间,且减少了电动车刹把断电安全装置的改装工序,有利于推广。
