Description

Technical Field

[0001] This invention relates to a QR code charging system for electric vehicles, belonging to the field of charging pile technology. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings, residential parking lots, or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Currently, charging piles generally lack protective measures for their charging plugs, resulting in poor waterproofing and dustproofing, significantly reducing the lifespan of the plugs. Furthermore, typical charging piles have limited functionality, unable to display advertisements, thus reducing their commercial value. Summary of the Invention

[0003] The purpose of this invention is to provide a QR code charging system for electric vehicles. This QR code charging system for electric vehicles is convenient to remove the charging plug for use, and can also be used for maintenance when not in use, preventing external personnel from touching it and preventing outsiders from forcibly disassembling and removing the charging plug, thus providing strong security.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a charging pile for new energy vehicles, comprising a pile body, a spiral spring installed inside the pile body, a friction wheel installed at the top of the spiral spring, a telescopic rod installed at the top of the friction wheel, a support plate installed on the outer wall of the telescopic rod, a control box installed at the bottom of the spiral spring, a controller installed inside the control box, a wireless receiver installed at the top of the controller, and a control switch installed on the surface of the control box;

[0005] A socket is provided on one side of the pile body, and a charging plug is fitted inside the socket. An electric wire is connected to the side of the charging plug near the inside of the pile body. The end of the electric wire away from the charging plug is wound in the gap of the spiral spring. An indicator light is installed at the bottom of the charging plug. A status light is installed at the bottom of the indicator light. A maintenance light is installed at the bottom of the status light. A first ball socket and a second ball socket are respectively provided on both sides of the charging plug. Rubber pads are attached to the side of the first ball socket and the second ball socket that are arc-shaped near the charging plug. A support rod is installed on the side of the first ball socket and the second ball socket that are near the inside of the pile body. A nut bushing is installed on the other side of the support rod. A single-turn reciprocating screw is installed inside the pile body at a position corresponding to the nut bushing. The single-turn reciprocating screw is slidably connected to the nut bushing, and a first motor is installed on one end of the single-turn reciprocating screw. The first motor is installed on the inner wall of the pile body by bolts. Two spiral grooves with opposite directions of rotation are provided on the outer wall of the single-turn reciprocating screw.

[0006] An active roller is installed on the output end of the second motor, and a driven roller is installed on one side of the active roller. The driven roller is connected to the inner wall of the pile body through a bearing, and advertising strips are sleeved on the outer walls of both the driven roller and the active roller. The active roller is rotatably connected to the driven roller through the advertising strips. A QR code is installed on the top of the pile body. The telescopic rod, wireless receiver, controller, signal light, status light, maintenance light, first motor and second motor are all electrically connected to a control switch, and the control switch is electrically connected to an external power source.

[0007] The following are further improvements to the above technical solution:

[0008] 1. In the above scheme, the outer wall of the charging plug has a conical structure.

[0009] 2. In the above solution, four wheel grooves are provided on the outer wall of the charging plug, and the four wheel grooves are arranged at equal intervals on the outer wall of the charging plug. A wheel rod is hinged inside the wheel groove, and a shock-absorbing wheel is installed on the end of the wheel rod away from the wheel groove.

[0010] 3. In the above scheme, the side wall of the wheel rod is connected to the wheel groove by a spring.

[0011] 4. In the above scheme, anti-glare glass is installed on the outer wall of the pile at the position corresponding to the advertising strip.

[0012] Due to the application of the above technical solution, the present invention has the following advantages and effects compared with the prior art:

[0013] 1. The electric vehicle QR code charging system of the present invention has four shock-absorbing wheels installed on the outer wall of the charging plug of the charging pile. When the charging plug is reset, the consumer does not need to manually return it to its original position, which brings convenience to the consumer. The shock-absorbing wheels can be placed on the ground, and the adjacent shock-absorbing wheels roll on the ground in a figure-eight shape, making the charging plug more stable and preventing the charging plug from being worn or damaged due to collisions caused by swinging. In addition, a pair of ball sockets are installed on the charging plug. The ball sockets can be brought together by the drive of a single-rotation reciprocating screw and cover the charging plug, which can play a role in waterproofing and dustproofing. At the same time, due to the smooth surface, it is not convenient to apply force, preventing outsiders from maliciously disassembling and removing the charging plug.

[0014] 2. The electric vehicle QR code charging system of the present invention has three indicator lights, which are clear and easy to understand: a signal light, a status light, and a maintenance light. When the signal light is on, it indicates that the charging plug is available; when the status light is on, it indicates that the charging time has ended; and when the maintenance light is on, it indicates that the charging plug is unavailable. Furthermore, the charging pile has an internal drive roller and a driven roller, and the outer wall is fitted with a conveyor belt printed with advertising patterns. A second motor can rotate, driving the advertising belt to move under the rotation of the drive roller and the driven roller, changing different types of advertisements for pedestrians or consumers waiting to charge, greatly improving the commercial value of the charging pile.

[0022] The present invention will be further described below with reference to embodiments:

[0023] Example: A QR code charging system for electric vehicles includes a charging pile 1. A spiral spring 19 is installed inside the charging pile 1. A friction wheel 18 is installed at the top of the spiral spring 19. A telescopic rod 16 is installed at the top of the friction wheel 18. A support plate 17 is installed on the outer wall of the telescopic rod 16. A control box 20 is installed at the bottom of the spiral spring 19. A controller 21, model MAM-330, is installed inside the control box 20. A wireless receiver 22, model YS-53, is installed at the top of the controller 21. A control switch 23 is installed on the surface of the control box 20.

[0024] A socket 3 is provided on one side of the pile body 1. A charging plug 4 is fitted inside the socket 3. A wire is connected to the side of the charging plug 4 closest to the inside of the pile body 1. The end of the wire away from the charging plug 4 is wound in the gap of the spiral spring 19. An indicator light 8 is installed at the bottom of the charging plug 4. A status light 9 is installed at the bottom of the indicator light 8. A maintenance light 10 is installed at the bottom of the status light 9. A first ball socket 6 and a second ball socket 7 are respectively provided on both sides of the charging plug 4. A support rod 25 is installed on the side of the first ball socket 6 and the second ball socket 7 closest to the inside of the pile body 1. A nut bushing is installed on the other side of the support rod 25. A single-turn reciprocating screw 24 is installed inside the pile body 1 at the position corresponding to the nut bushing. The single-turn reciprocating screw 24 is slidably connected to the nut bushing, and a first motor 26 is installed on one end of the single-turn reciprocating screw 24. The first motor 26 is a stepper motor with the model number JK28-003-104. The first motor 26 is installed on the inner wall of the pile body 1 by bolts.

[0025] A second motor 12 is installed at the top inside the pile body 1. The second motor 12 is a stepper motor, model 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. An advertising strip 15 is fitted on the outer wall of both the driven roller 14 and the active roller 13. The active roller 13 is rotatably connected to the driven roller 14 through the advertising strip 15. A QR code label 2 is installed at the top of the pile body 1. The telescopic rod 16, wireless receiver 22, controller 21, signal light 8, status light 9, maintenance light 10, first motor 26 and second motor 12 are all electrically connected to the control switch 23. The control switch 23 is electrically connected to an external power source.

[0026] In this embodiment: the outer wall of the charging plug 4 is a conical structure, and four wheel grooves 28 are provided on the outer wall of the charging plug 4. 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 by a spring 31. After charging is completed, the consumer can directly unplug the charging plug 4. At this time, the power cord is wound up by the spiral spring 19, which drives the charging plug... As the head 4 retracts, the two adjacent shock-absorbing wheels 29 on the outer wall of the charging plug 4 will roll on the ground in a figure-eight pattern, making it more stable and preventing the charging plug 4 from being thrown around due to excessive retraction speed, which would cause wear on the charging plug 4. At the same time, it eliminates the need for consumers to manually reset the charging plug 4, providing convenience for consumers. The charging plug 4 will eventually be embedded in the socket 3, and the shock-absorbing wheels 29 and wheel rods 30 will be squeezed into the wheel grooves 28 due to the narrow space of the socket 3. At the same time, the hinge of the wheel rods 30 will rotate, and the spring 31 will contract.

[0027] A pull ring 5 is hinged to the side wall of the charging plug 4 away from the station body 1. The pull ring 5 helps the consumer pull out the charging plug 4 and avoids direct contact with the connector on the charging plug 4, thus preventing the connector from getting dust and sweat from the hands, or even generating static electricity with the human body and causing discomfort.

[0028] Rubber pads 27 are attached to the side of the first ball socket 6 and the second ball socket 7 near the charging plug 4. During maintenance, the first ball socket 6 and the second ball socket 7 move closer together and close, while the rubber pads 27 are squeezed against each other, which serves to prevent dust and water. Since the surfaces of the first ball socket 6 and the second ball socket 7 are arc-shaped and smooth, it is not convenient to apply force, which prevents outsiders from forcibly disassembling and removing the charging plug 4, thus ensuring strong safety.

[0029] Anti-glare glass 11 is installed on the outer wall of the pile body 1 at the position corresponding to the advertising strip 15, so as to avoid discomfort to pedestrians' eyes due to glare while advertising is being carried out;

[0030] The outer wall of the single-turn reciprocating screw 24 is provided with a spiral groove. There are two spiral grooves, and the two spiral grooves rotate in opposite directions. When the single-turn reciprocating screw 24 rotates, due to the different rotation directions of the two spiral grooves, the nut bushing on the spiral groove moves in two ways: one is away from each other, and the other is close to each other. This achieves the separation of the first ball socket 6 and the second ball socket 7, so that the charging plug 4 can be taken out for use, or the first ball socket 6 and the second ball socket 7 can be closed to maintain the charging plug 4 and prevent external personnel from touching it.

[0031] Working principle: When using this invention, the consumer scans the QR code on the top of the pile 1 and receives the command signal through the wireless receiver 22. This causes the controller 21 to send feedback to the telescopic rod 16, at which point the telescopic rod 16 moves and extends, causing the friction wheel 18 at the end to contact and press against the lower vortex spring 19. This causes the wire wound in the vortex spring 19 to be pulled out but not rewound. Then, the first motor 26 rotates, driving the single-turn reciprocating screw 24 to rotate. At the same time, the nut bushings on the two threaded grooves move in opposite directions, causing the first ball socket 6 and the second ball socket 7 to separate. Consumers can hook their fingers onto the pull ring 5 and pull it outwards. At this time, the power cord and charging plug 4 are pulled out together, connecting the charging plug 4 to the new energy vehicle. The indicator light 8 illuminates. Once charging is complete, the status light 9 illuminates. The consumer can then unplug the charging plug 4 and place it on the ground. After sending a signal to the wireless receiver 22, the controller 21 receives the instruction, causing the telescopic rod 16 to retract. The friction wheel 18 separates from the vortex spring 19, releasing the previously stored energy. The vortex spring 19 then self-winds, causing the power cord to wind up as well. When the charging plug 4 is pulled back, the two adjacent shock-absorbing wheels 29 on its outer wall will roll on the ground in a figure-eight pattern, making it more stable and preventing the charging plug 4 from being thrown around due to excessive speed, which would cause wear on the charging plug 4. The charging plug 4 will eventually be embedded in the socket 3, while the shock-absorbing wheels 29 and wheel rods 30 will be squeezed into the wheel grooves 28 due to the narrow space of the socket 3. At the same time, the hinge of the wheel rod 30 will rotate, the spring 31 will contract, and then the first motor 26 will drive the single-rotation reciprocating screw 24 to rotate in the opposite direction, causing the first ball socket 6 and the second ball socket 7 to move closer together, thus securing the charging plug. The head 4 is covered, and the rubber pads 27 on both sides fit tightly, providing dustproof, waterproof, and protective functions. During maintenance, the maintenance light 10 remains on, while the indicator light 8 and status light 9 are not activated. Simultaneously, the second motor 12 drives the active roller 13 to rotate, which in turn drives the driven roller 14 via the advertising belt 15. This changes the position of the advertising pattern on the advertising belt 15 corresponding to the anti-glare glass 11, allowing for different types of advertisements to be viewed by pedestrians or consumers waiting to charge, greatly enhancing the commercial value of the charging station. The entire workflow is then complete. Content not described in detail in this specification constitutes prior art known to those skilled in the art.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
