[0025] A rotating member 6 is installed on the support plate 13, and the rotating member 6 includes a rotating motor 64, a driving wheel 63, a driven wheel 62 and a rotating shaft 61.

[0027] When the electric vehicle needs to be charged near the charging pile 1, the staff adjusts the driving motor 51, and the output shaft of the driving motor 51 rotates to drive the screw 52 to rotate synchronously. Under the limiting action of the limiting rod, the lifting plate 54 is lifted and lowered in the vertical direction, thereby driving the support plate 13 to lift and lower synchronously. When the lifting plate 54 is lifted and lowered to the set height, the staff starts the rotating motor 64, and the output shaft of the rotating motor 64 rotates to drive the driving wheel 63 to rotate synchronously. The driven wheel 62 is meshed with the driving wheel 63 and rotates with the driving wheel 63, thereby driving the rotating shaft 61 to rotate synchronously. The rotation of the rotating shaft 61 drives the support plate 13 to rotate synchronously, thereby converting the support plate 13 from a vertical setting to a horizontal setting. The staff then starts the pushing cylinder 24 to push the air ... The piston rod of the cylinder 24 is extended and retracted to drive the push rod 23 to move synchronously. Through the push block 22 and the push slot 31, the push plate 21 moves along the axial direction of the push rod 23, thereby driving the buffer rod 42, the electromagnet 41 and the charging gun 11 to move synchronously. At the same time, the staff starts the driving cylinder 83, and the piston rod of the driving cylinder 83 is extended and retracted to drive the driving rod 82 to move synchronously. Through the driving block 81 and the driving slot 32, the push plate 21 moves synchronously until the buffer rod 42, the electromagnet 41 and the charging gun 11 are transmitted to the set position, and the charging gun 11 is plugged into the charging port of the electric vehicle. At this time, the electromagnet 41 is energized, so that the electromagnet 41 is adsorbed on the shell of the electric vehicle, thereby limiting the electromagnet 41 and the charging gun 11 and improving the stability of the charging gun 11. At the same time, there is no need for the staff to hold the charging gun 11 and plug it into the charging port of the electric vehicle, thereby reducing manual operation errors such as unstable docking of the charging gun 11 and the wrong cable insertion, and improving charging safety.

[0028] A slide rail 71, a slider 72, and a transmission plate 73 are installed on the side wall of the charging pile 1, and a transmission cylinder 74 and a transmission rod 75 are installed on the top of the charging pile 1. There are two vertically arranged slide rails 71, and both slide rails 71 are located on one side of the transmission slot 12, and the side wall of the slide rail 71 is fixedly connected to the side wall of the charging pile 1, there are two vertically arranged sliders 72, and both sliders 72 are located in the slide rail 71 and are slidably connected to the slide rail 71, the vertically arranged transmission plate 73 is located on one side of the slider 72, and the side wall of the transmission plate 73 is fixedly connected to the side wall of the slider 72, and the transmission plate 73 is used to cover the transmission slot 12. A transmission cylinder 74, a transmission block 76 and a transmission rod 75 are installed on the top of the transmission plate 73. The transmission cylinder 74 is located at the top of the charging pile 1 and is fixedly connected to the charging pile 1. The piston rod of the transmission cylinder 74 is vertically arranged upward, and the piston rod of the transmission cylinder 74 is coaxially fixedly connected to the transmission rod 75. The top of the vertically arranged transmission rod 75 is fixedly connected to the bottom of the transmission block 76, and the end of the horizontally arranged transmission block 76 is fixedly connected to the top of the transmission plate 73.

[0029] The staff starts the transmission cylinder 74, and the piston rod of the transmission cylinder 74 extends and retracts to drive the transmission rod 75 to rise and fall synchronously, thereby driving the transmission block 76 to move synchronously. Through the slide rail 71 and the slider 72, the transmission plate 73 rises and falls in the vertical direction, so that the transmission plate 73 covers the transmission slot 12, thereby reducing dust and other dirt from being transmitted to the charging pile 1 after passing through the transmission slot 12, improving the cleanliness of the charging pile 1, and thus extending the service life of the charging pile 1.

[0030] The working principle of the present invention is as follows: When the intelligent charging device with autonomous mobile precise positioning function of this embodiment is in use, when the electric car is transferred to the vicinity of the charging pile 1, the staff starts the transmission cylinder 74, and the piston rod of the transmission cylinder 74 is lifted and lowered to drive the transmission rod 75 to lift and lower synchronously, thereby driving the transmission block 76 and the transmission plate 73 to lift and lower in the vertical direction until the transmission plate 73 is separated from the transmission slot 12. The staff starts the driving motor 51, and the output shaft of the driving motor 51 rotates to drive the screw 52 to rotate synchronously. Through the lifting rod 53, the lifting plate 54 is lifted and lowered in the transmission slot 12. When the lifting plate 54 is lifted and lowered to the set height, the staff starts the rotating motor 64 again, and the output shaft of the rotating motor 64 rotates to drive the driving wheel 63 to rotate, thereby driving the driven wheel 62 to rotate synchronously, and the driven wheel 62 rotates to drive the rotating shaft 61 to rotate synchronously, and the rotating shaft 61 rotates to drive the support plate 13 to rotate synchronously, so that the support plate 13 rotates to the set angle, and the staff starts the pushing cylinder 24 and the driving cylinder 83 again to adjust the pushing plate 21 and the position of the charging gun 11, so that the push plate 21 is transmitted to the set position, so that the charging gun 11 is plugged into the charging port of the electric vehicle. At this time, the staff adjusts the electromagnet 41 to make the electromagnet 41 contact with the shell of the electric vehicle, so that the electromagnet 41 is magnetically connected to the shell of the electric vehicle, thereby limiting the charging gun 11, improving the stability of the charging gun 11, and saving the workload of the staff. At the same time, there is no need for the staff to hold the charging gun 11 and plug it into the charging port of the electric vehicle, thereby reducing manual operating errors such as unstable docking of the charging gun 11 and incorrect cable insertion, thereby improving charging safety.
