The invention relates to the technical field of intelligent science and technology, and discloses an automatic lifting foreign matter entering prevention device for an electric vehicle charging pile, the device comprises the charging pile and an extrusion mechanism, the interior of the charging pile comprises a shell, an arch frame is fixedly connected to the top of the inner wall of the shell, and a plug pin is movably connected to the surface of the arch frame; the surface of the bolt is movably connected with a bending guide rail, the surface of the bending guide rail is movably connected with a charging head, the surface of the charging head is movably connected with a connecting rod, the other end of the connecting rod is movably connected to the surface of the bolt, the charging head moves towards the two sides along the surface of the bending guide rail, the charging head extrudes the inclined face of the inclined plate, and the two baffles are separated. The bending guard rail extends out of the side surface of a charging opening. The top end of the telescopic rod extrudes liquid at the bottom of an inner cavity of the guide column, and the liquid in the inner cavity of the guide column flows towards the hydraulic cylinder through the liquid guide pipe, applies pressure to the hydraulic cylinder, drives the hydraulic cylinder to move towards the side faces and extrudes the inner wall side faces of the shell towards the two sides, and gaps between the two side faces of the shell and the outside are reduced.

    本发明涉及智能科技技术领域,且公开了一种电动汽车充电桩用可自动升降防止异物进入的装置,包括充电桩、挤压机构,所述充电桩的内部包括外壳,外壳的内壁顶部固定连接有拱架,拱架的表面活动连接有插销,插销的表面活动连接有弯折导轨,弯折导轨的表面活动连接有充电头,充电头的表面活动连接有连杆,连杆的另一端活动连接在插销的表面,充电头沿着弯折导轨的表面向两侧移动,充电头挤压斜板的斜面,两挡板分离,弯折导轨从充电口的侧面伸出,伸缩杆的顶端挤压导向柱内腔底部液体,导向柱内腔的液体通过导液管向液缸流动,对液缸施压,带动液缸向侧面移动,向两侧挤压外壳的内壁侧面,减小外壳两侧面与外部的空隙。
