The invention belongs to the technical field of new energy charging piles, and discloses a new energy automobile charging pile with an electric leakage detection function, the new energy automobile charging pile comprises a charging pile body and a charging gun, an outer cover is arranged on the outer surface of the charging gun, and a protection cover and a spring are movably sleeved with the outer cover. When the charging pile detects the electric leakage phenomenon, the charging pile immediately supplies reverse current to the electromagnet, the electromagnet attracts the first magnetic block, the first magnetic block and the clamping block are synchronously separated from the clamping groove of the protection cover, the protection cover loses limiting and fixing, the spring is released to abut against the protection cover, and the protection cover is driven to slide forwards; the front end of the protection cover naturally abuts against the edge part of the charging port of the automobile, the plug of the charging gun is pulled out through counter-acting force, the protection cover just wraps the plug part of the charging gun, the charging gun is forcibly pulled out of the charging port of the automobile, the thorough insulation effect is achieved, and the automobile and the charging pile are protected against further damage.

    本发明属于新能源充电桩技术领域,且公开了一种具有漏电检测功能的新能源汽车充电桩,包括充电桩本体和充电枪,所述充电枪的外表面设有外罩,所述外罩的内部活动套设有保护罩和弹簧。本发明通过当充电桩检测到漏电现象的发生时,充电桩会立即为电磁铁通反向电流,令电磁铁将一号磁块吸起来,一号磁块和卡块同步脱离保护罩的卡槽,保护罩失去限位固定,弹簧释放将保护罩顶住向前滑移,保护罩的前端自然会抵住汽车的充电口边缘部分,利用反作用力将充电枪的插头抽出来,保护罩正好也会将充电枪的插头部位包覆在内侧,强制令充电枪抽离汽车充电口,达到彻底绝缘的效果,保护汽车和充电桩不受进一步损坏。
