A wire is connected to the side of the charging plug 4 close to the inside of the pile body 1, and the end of the wire away from the charging plug 4 is wound in the gap of the vortex spring 19. A signal light 8 is installed at the bottom end of the charging plug 4, a status light 9 is installed at the bottom end of the signal light 8, and a maintenance light 10 is installed at the bottom end of the status light 9. A first ball socket block 6 and a second ball socket block 7 are respectively provided on both sides of the charging plug 4. A support rod 25 is installed on one side of the first ball socket block 6 and the second ball socket block 7 close to the inside of the pile body 1, and a nut bushing is installed on the other side of the support rod 25. A single-rotation reciprocating screw 24 is installed at a position corresponding to the nut bushing in the pile body 1. The single-rotation reciprocating screw 24 is slidably connected to the nut bushing, and a first motor 26 is installed on one end of the single-rotation reciprocating screw 24. The first motor 26 is a stepper motor, and its stepper motor model is JK28-003-104. The first motor 26 is installed on the inner wall of the pile body 1 by bolts; A second motor 12 is installed at the top of the pile body 1. The second motor 12 is a stepping motor with a model of JK28-003-104. An active roller 13 is installed on the output end of the second motor 12. A driven roller 14 is installed on one side of the active roller 13. The driven roller 14 is connected to the inner wall of the pile body 1 through a bearing, and an advertising belt 15 is sleeved on the outer walls of the driven roller 14 and the active roller 13. The active roller 13 is rotatably connected to the driven roller 14 through the advertising belt 15. A QR code logo 2 is installed at the top of the pile body 1. The telescopic rod 16, the wireless receiver 22, the controller 21, the signal light 8, the status light 9, the maintenance light 10, the first motor 26 and the second motor 12 are all electrically connected to the control switch 23, and the control switch 23 is electrically connected to the external power supply.

[0014] In this embodiment, the outer wall of the charging plug 4 is a conical structure, and a wheel groove 28 is opened on the outer wall of the charging plug 4. There are four wheel grooves 28, and the four wheel grooves 28 are arranged at equal intervals on the outer wall of the charging plug 4. A wheel rod 30 is hinged inside the wheel groove 28. A shock-absorbing wheel 29 is installed on the end of the wheel rod 30 away from the wheel groove 28, and the side wall of the wheel rod 30 is connected to the wheel groove 28 through a spring 31. After charging is completed, the consumer can directly unplug the charging plug 4. At this time, the wire is rolled up by the vortex spring 19, driving the charging plug The charging plug 4 is retracted, and the two adjacent shock-absorbing wheels 29 on the outer wall of the charging plug 4 will roll on the ground in an "eight" structure, which is more stable and avoids the charging plug 4 being thrown around due to the withdrawal speed being too fast, causing wear of the charging plug 4. At the same time, there is no need for consumers to manually reset the charging plug 4, which provides convenience for consumers. The charging plug 4 will eventually be embedded in the socket 3, and the shock-absorbing wheel 29 and the wheel rod 30 will be squeezed in the wheel groove 28 due to the narrow space of the socket 3. At the same time, the hinge of the wheel rod 30 rotates, and the spring 31 contracts; A pull ring 5 is hinged on the side wall of the charging plug 4 away from the pile body 1. The pull ring 5 helps consumers pull out the charging plug 4 to avoid direct contact with the connector on the charging plug 4, so as to avoid the connector being stained with dust and sweat on the hands, or even generating static electricity with the human body, causing discomfort; The first ball socket block 6 and the second ball socket block 7 are both attached with a rubber pad 27 on one side close to the charging plug 4. During maintenance, the first ball socket block 6 and the second ball socket block 7 are brought close to each other and closed, and the rubber pads 27 are squeezed against each other to prevent dust and water. Since the surfaces of the first ball socket block 6 and the second ball socket block 7 are curved and smooth, it is not convenient to apply force, so that outsiders are prevented from forcibly disassembling and removing the charging plug 4, and the safety is relatively strong. An anti-glare glass 11 is installed on the outer wall of the pile body 1 at a position corresponding to the advertising belt 15, so as to prevent discomfort to pedestrians' eyes caused by glare while carrying out advertising; A spiral groove is provided on the outer wall of the single-rotation reciprocating screw 24. There are two spiral grooves, and the two spiral grooves rotate in opposite directions. When the single-rotation reciprocating screw 24 rotates, due to the different rotation directions of the two spiral grooves, the movement direction of the nut bushing on the spiral groove has two forms, one is to move away from each other, and the other is to move closer to each other, thereby realizing the separation of the first ball socket block 6 and the second ball socket block 7, and the charging plug 4 can be taken out for use, or the first ball socket block 6 and the second ball socket block 7 can be closed to maintain the charging plug 4 and avoid touch by outsiders.

[0015] Working principle: When the present invention is used, the consumer scans the QR code table logo on the top of the pile body 1, and receives the command signal through the wireless receiver 22, so that the controller 21 feeds back to the telescopic rod 16. At this time, the telescopic rod 16 moves and extends, so that the friction wheel 18 at the end contacts and squeezes the vortex spring 19 at the lower end, so that the wire wound in the vortex spring 19 can only be pulled out but cannot be reeled in. Then the first motor 26 rotates, driving the single-rotation reciprocating screw 24 to rotate, and at the same time, the nut bushings on the two threaded grooves move in the opposite direction, so that the first ball socket block 6 and the second ball socket block 7 are separated, and then The consumer can hook the pull ring 5 with his fingers and pull it outwards. At this time, the wire is unplugged together with the charging plug 4, and the charging plug 4 is connected to the new energy vehicle. At this time, the signal light 8 lights up, and when the charging is completed, the status light 9 lights up. The consumer can unplug the charging plug 4 and put it on the ground. After sending a signal to the wireless receiver 22, the controller 21 receives the command, causing the telescopic rod 16 to shrink, and the friction wheel 18 is separated from the vortex spring 19. At this time, the energy stored in the vortex spring 19 is released, and the vortex spring 19 retracts itself and drives the wire to reel. When the charging plug 4 is pulled back, the two adjacent shock-absorbing wheels 29 on the outer wall of the charging plug 4 will roll on the ground in an "eight" structure, which is more stable, avoiding the charging plug 4 from being thrown around due to the excessive withdrawal speed, causing the charging plug 4 to be worn, and the charging plug 4 will eventually be embedded in the socket 3, and the shock-absorbing wheel 29 and the wheel rod 30 will be squeezed in the wheel groove 28 due to the narrow space of the socket 3. At the same time, the hinge of the wheel rod 30 rotates, the spring 31 contracts, and then the first motor 26 drives the single-rotation reciprocating screw 24 to rotate in the opposite direction, so that the first ball socket block 6 and the second ball socket block 7 are close to each other, and the charging plug The head 4 is covered, and the rubber pads 27 on both sides are tightly fitted, which plays a role in dustproof, waterproof and protective. During maintenance, the maintenance light 10 is always on, while the signal light 8 and the status light 9 do not work. At the same time, the second motor 12 will drive the active roller 13 to rotate, and the active roller 13 drives the driven roller 14 to move through the advertising belt 15, thereby changing the advertising pattern on the advertising belt 15 and the position corresponding to the anti-glare glass 11, replacing different types of advertisements for pedestrians or consumers waiting for charging to watch, greatly improving the commercial value of the charging pile, and the entire workflow is completed. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
