The invention discloses a new energy automobile charging pile which comprises a fixing mechanism, a contraction mechanism, an auxiliary mechanism and a protection mechanism. One end of the fixing mechanism is fixedly connected with one end of the contraction mechanism, the auxiliary mechanism is located in the contraction mechanism, and the contraction mechanism is located in the protection mechanism; the new energy automobile charging pile can effectively prevent a charging head from falling off during charging, a fixing plate makes contact with the inner wall of an automobile charging cavity, plugging and pulling are facilitated, under the action of a telescopic spring and a clamping plate, the device is suitable for fixing the automobile charging cavities with different depths, vibration driven by the outside of the device is reduced and the phenomenon that the connector falls off is prevented. Through sealing of the rainproof cover, charging interruption caused by the fact that the connector is stained with water is prevented, meanwhile, under the action of the rubber suction cup, the rainproof cover and the shell of the automobile can be firmly adsorbed, the interior of the rainproof cover is in a sealed state through the sealing ring, and the water suction ring and the drying ring can prevent the water inflow phenomenon.
