The invention discloses a high-safety new energy automobile charging device which comprises a charging box, a supporting rod, a fixing base and a charging connector. An external thread connecting piece is arranged on the front end face of the charging box. A through hole is formed inside the external thread connecting piece. A pluggable hole is formed in the portion, on the rear side of the through hole, inside the charging box. A conductive insertion rod is arranged on the inner wall of the rear side of the pluggable hole. A first cavity is arranged in the portion, behind the pluggable hole, inside the charging box. A sediment groove is formed in the inner wall of the rear side of the first cavity. A movable block is arranged inside the first cavity on the front side of the sediment groove. A top pressure spring is arranged between the sediment groove and the end face of the rear side of the movable block. Guide rods are symmetrically arranged at the portions, on the two sides of the top pressure spring, inside the first cavity. The guide rods are connected with the movable block in a sliding-fit mode. The front end side of the movable block is provided with a top pressure rod penetrating through the inner wall of the charging box and stretching into the pluggable hole. Grooves are formed in the end walls of the left and right sides of the movable block. Spline rotating shafts are symmetrically arranged at the portion, on the outer side of the movable block, inside the first cavity, and the rear side ends of the spline rotating shafts are in power connection with a motor. The automobile charging device is simple in structure, stable in charging connection and high in safety.

The invention provides a power plugging device comprising an electrical socket and an electrical connector. The electrical socket includes an insertion slot with the opening facing the front end; a counter bore is formed in the bottom of the insertion slot; and a sensor is arranged in the counter bore. The electrical connector consists of a plugging cavity and sliding cavities arranged at the leftside and the right side of the plugging cavity; an electric connection body having the front end with an electric connection part and a first motor are arranged in the plugging cavity; the electric connection body and the first motor are connected by a first screw rod; a power supply body and a second motor are arranged at the front end of the plugging cavity; the power supply body is provided with a power supply slot cooperating with the electric connection part; and the power supply body and the second motor are connected by a second screw rod. The sensor sends a control signal to control the operation of the first motor and the second motor. According to the power plugging device, delayed electrification is realized and loosening during the electrification process is prevented; and with the power plugging device, the operation becomes safe and convenient.
