The invention relates to the technical field of charging piles, and discloses an electric vehicle charging pile capable of being automatically powered off when being impacted. The electric vehicle charging pile comprises a base, the top of the base is fixedly connected with a fixed cylinder, the top of the fixed cylinder is fixedly connected with a fixed seat, and the outer part of the fixed cylinder is inserted with eight annularly arranged extrusion rods; and the outer parts of the eight extrusion rods are all connected with damping springs, the opposite sides of the eight extrusion rods are all fixedly connected with top plates, the outer parts of the eight top plates are connected with rubber rings, a movable rod is inserted into the top of the fixed seat, the bottom of the movable rod is fixedly connected with a wedge-shaped block, and the top of the movable rod is rotatably connected with two connecting rods. When a vehicle collides with the charging pile, the extruded side of each rubber ring drives the extrusion rods to move in the direction close to the wedge-shaped block through a top plate, the damping springs are compressed, the impact force of the vehicle on the charging pile is counteracted through elastic buffering of the rubber rings and the damping springs, and the vehicle and the charging pile are prevented from being damaged.
本发明涉及充电桩技术领域,且公开了一种受到撞击时可自动断电的电动汽车用充电桩,包括底座,所述底座的顶部固定连接有固定筒,所述固定筒的顶部固定连接有固定座,所述固定筒的外部插接有八个环形排列的挤压杆,八个所述挤压杆的外部均套接有减震弹簧,八个所述挤压杆相背的一侧均固定连接有顶板,八个所述顶板外部套接有橡胶环,所述固定座的顶部插接有活动杆,所述活动杆的底部固定连接有楔形块,所述活动杆的顶部转动连接有两个连杆。通过车辆与充电桩发生碰撞时,橡胶环受到挤压的一侧会通过顶板带动挤压杆向靠近楔形块的方向移动,减震弹簧受到压缩,通过橡胶环和减震弹簧的弹力缓冲抵消车辆对充电桩的撞击力,避免了车辆和充电桩损坏。
