Technical Field
[0001] The present invention relates to the technical field of charging piles, and specifically to a new energy vehicle charging pile with electric shock prevention. Background Art
[0002] A new energy vehicle charging pile, also known as an electric vehicle charging station or an electric vehicle power supply device, is a device that provides electric energy for an electric vehicle, enabling the electric vehicle to store sufficient electric energy to support its operation; charging piles can be classified into floor-mounted charging piles and wall-mounted charging piles according to the installation method. A related art provides a new energy charging pile, including an installation base and an intelligent operation panel. The top of the installation base is fixedly connected with a pile body. One side of the bottom of the inner wall of the pile body is fixedly connected with an insulating board. An external charging device is arranged inside the insulating board. One side of the top of the insulating board is fixedly connected with a servo motor. A gear is fixedly connected to the output shaft of the servo motor. A lifting rack is arranged on one side of the gear. A T-shaped slider is fixedly connected to one side of the lifting rack. A T-shaped chute is formed in the middle of the other side of the inner wall of the pile body. A cross bar is fixedly connected to the other side of the lifting rack. An electric shock prevention plug is fixedly connected to the bottom of the side of the cross bar away from the lifting rack. A charging wire is fixedly connected to the top of the electric shock prevention plug. A U-shaped support plate is fixedly connected to the top of the side of the cross bar away from the lifting rack. A support shaft is fixedly connected to the top of the U-shaped support plate. A wire reel is sleeved in the middle of the support shaft. A leakage protector is fixedly connected to the side of the top of the insulating board away from the servo motor. A power supply rod is fixedly connected to the top of the leakage protector. A power supply jack is fixedly connected to the top of the side of the power supply rod away from the leakage protector. A heat dissipation fan is fixedly connected to the bottom of the side of the pile body close to the external charging device. A dust-proof net is fixedly connected to the side of the heat dissipation fan away from the pile body. A dust-proof cover is fixedly connected to the middle of the outer wall of the pile body away from the heat dissipation fan. A charging plug is arranged inside the dust-proof cover. A rain shield is fixedly connected to the top of the outer wall of the pile body away from the heat dissipation fan. For this new energy charging pile, by setting an electric shock prevention plug, a power supply jack and a leakage protector, the servo motor is used to drive the electric shock prevention plug to cooperate with the power supply jack, and the charging plug is in the powered-on state; when the electric shock prevention plug and the power supply jack are in the separated state, the charging plug is in the powered-off state, which can effectively prevent the operator from getting an electric shock; however, this method also has some defects. For example, the motor is used to drive the gear to drive the rack to lift, and when the rack lifts, it drives the electric shock prevention plug to cooperate with and separate from the power supply jack. Controlling the contact between the electric shock prevention plug and the power supply jack by the motor is relatively slow in terms of movement speed, and there is easily a time difference, resulting in a delay when the charging pile performs a charging operation. Moreover, with long-term and multiple uses, wear occurs between the gear and the lifting rack, and it is very easy for the gear to slip when rotating, and it cannot drive the lifting rack to lift to achieve the power-on operation. In view of the problems in the above-mentioned background technology, the present invention aims to provide a new energy vehicle charging pile that prevents electric shock. Summary of the Invention

[0009] Compared with the prior art, the beneficial effects of the present invention are: The anti-electric shock new energy vehicle charging pile changes the original way of driving the rack to lift through a motor-driven gear, and when the rack lifts, it drives the anti-electric shock plug to cooperate with and separate from the power supply jack.
