The invention discloses an environment-friendly safe new energy automobile charging pile which comprises an underground embedded body which is buried underground and is in an ''inverted-L'' shape anda charging shell fixed to the ground surface. The underground embedded body is sequentially provided with a thick hydraulic flow channel, a thin hydraulic flow channel and a transmission cavity from right to left, and the thick hydraulic flow channel and the thin hydraulic flow channel are connected with each other; a first piston and a second piston are connected into the thick hydraulic flow channel and the thin hydraulic flow channel in a sealed and sliding mode correspondingly, the position, between the first piston and the second piston, of the thick hydraulic flow channel and the thin hydraulic flow channel is filled with hydraulic oil, and a first piston rod is fixedly connected to the upper end of the first piston; and the upper end of the first piston rod penetrates through the thick hydraulic flow channel and is fixedly connected with a pressing plate, and the first piston rod is movably connected with a first spring. The charging pile has the advantages that an electric shock accident can be avoided in a non-charging state, and when charging is needed, the charging block can be exposed without additional power so that energy consumption is reduced.

    本发明公开了一种环保安全型新能源汽车充电桩,包括埋设在地下且呈“┛”的地下嵌体和固定在地表至上的充电壳体,所述地下嵌体从右至左依次开设有粗液压流道、细液压流道和传动腔,且粗液压流道与细液压流道相互连通,所述粗液压流道与细液压流道内分别密封滑动连接有第一活塞与第二活塞,所述粗液压流道与细液压流道在第一活塞与第二活塞之间填充有液压油,所述第一活塞的上端固定连接有第一活塞杆,所述第一活塞杆的上端贯穿粗液压流道并固定连接有压板,所述第一活塞杆上活动套接有第一弹簧。优点在于:本发明在非充电状态可以避免发生触电事故,在需要充电时,无需借助额外电力使充电块显露,节约能耗。
