The invention relates to the technical field of security and protection. The invention further discloses a safety protection device for an electric vehicle during short circuit. The device comprises adevice housing, a limiting rail is fixedly connected with the interior of the device housing; an indicating lamp switch is fixedly connected with the interior of the limiting rail, a sliding switch is slidably connected with the outer side of the limiting rail, a sliding groove is formed in the surface of the sliding switch, a contact switch is arranged on the lower side of the sliding groove, aspring is fixedly connected with the bottom of the contact switch, and one end of a connecting rod is slidably connected with the interior of the sliding groove. The invention discloses the safety protection device for the electric vehicle during short circuit. The limiting rail, the indicating lamp switch, the sliding switch, the sliding groove, a limiting rod, electromagnetic soft iron, an electric lead and a fault indicator light are used in cooperation; therefore, the effects that the working circuit can be automatically cut off when the electric vehicle is short-circuited or the working current is too large due to faults, the working circuit cannot be automatically recovered due to external reasons when the electric vehicle is not checked, and the fault indicator lamp is turned on areachieved.

    本发明涉及安防技术领域,且公开了一种电动车短路时的安全保护装置,包括装置外壳,所述装置外壳的内部固定连接有限制轨道,所述限制轨道的内部固定连接有指示灯开关,所述限制轨道的外侧滑动连接有滑动开关,所述滑动开关的表面设置有滑槽,所述滑槽的下侧设置有接触开关,所述接触开关的底部固定连接有弹簧,所述滑槽的内部滑动连接有连杆的一端。该电动车短路时的安全保护装置,通过限制轨道、指示灯开关、滑动开关、滑槽、限制杆、电磁软铁、导电线和故障指示灯的配合使用,从而达到了电动车短路或因故障引起工作电流过大时能自动切断工作电路,并不会在未检查时因为外部原因自动恢复工作电路,并亮起故障指示灯的效果。
