[0004] Traditional charging piles are generally fixed and installed on one side of a parking space. However, many fuel vehicles that do not need to be charged or vehicles that have been fully charged are still parked in the same place, causing most charging piles to be unusable. If mobile vehicles or other equipment are used to carry charging piles, inaccurate positioning is prone to occur, and various emergencies may occur during the driving of the mobile vehicle due to the immaturity of automatic navigation technology.

The hanging rail 1 is extended to the top of each parking space, and a QR code is set on the ground or wall of the position. Information is transmitted to the charging box 3 by scanning the QR code. A positioning device is set in the charging box 3 to control the charging box 2 to move to the corresponding hanging rail 1 position. Then, the charging box 3 is parallel to the outside by switching the seat 2 5, so that the charging box 3 does not affect the movement of other charging boxes 3 on the hanging rail 1. Then, the charging box 3 is The charging gun 20 is taken out and the charging gun 20 is used to charge the vehicle. Through this arrangement, since the hanging rail 1 is fixed above, the moving trajectory of the charging box 3 is fixed, and no complicated navigation and positioning equipment is required, ensuring that the charging box 3 can accurately arrive at the predetermined location. It is more suitable for underground parking lots and covered parking lots, and the charging box 3 will be called only when charging is needed. There will be no situation where vehicles that do not need to be charged, such as fuel vehicles, occupy the charging equipment.

This setting can ensure that the charging box 3 will not be affected by the new charging seat from the rear during charging. After moving into place, the charging seat 10 will extend the charging head, dock with the docking port 24 and charge. After charging is completed, the charging box 3 moves to the standby rail 6 to wait for the next delivery task.

[0052] When the charging box 3 moves to the bottom of the curved rail 2, the screw nut mechanism inside the switching seat 1 4 drives the two switching rails 13 to move, so that the curved rail 2 is aligned with one of the switching rails 13, and the charging box 3 is moved to the charging assembly, and the other switching rail 13 is used to receive the charged charging box 3, so that the charged charging box 3 can be moved to the curved rail 2 and the hanging rail 1, so that the two are staggered with each other, and do not affect the recovery and delivery of the charging box 3. The switching seat 2 5 uses the same structure. When the delivered charging box 3 moves to the switching rail 13 on the switching seat 2 5, the switching rail 13 and the charging box 3 are translated at the same time, and the other switching rail 13 replaces the original position, so that the entire hanging rail 1 remains passable; when the delivered charging box 3 meets the returning charging box 3, the returning charging box 3 will need the nearest empty switching seat 2 5 to move itself out in parallel, let the delivered charging box 3 move first, and then return itself;

[0053] The recovered charging box 3 will dock with the charging rail 7, and then the charging box 3 will move onto the charging rail 7 and move to the outside of the last charging seat 10. If the charging seat 10 in front has been used, it will move to the adjacent charging seat 10 for charging. This arrangement can ensure that the charging box 3 will not be affected by the new one coming from the back during the charging process. After moving into place, the charging seat 10 will extend the charging head, dock with the docking port 24 and charge. After charging is completed, the charging box 3 moves to the standby rail 6 to wait for the next delivery task.

[0054] When the charging box 3 is moved to the designated position, the closing plate 15 is opened, and the charging gun 20 is manually taken out. As the charging gun 20 is pulled outward, the connecting assembly is responsible for connecting the charging gun 20 and the power supply compartment 22, and the charging gun 20 is docked with the vehicle to complete the charging process;

[0055] The charging gun 20 is connected via a cable 25, and the other end of the cable 25 is connected to two metal contacts, which are two concentric rings and are located on the outside of the winding roller 23. In this way, when the winding roller 23 rotates, the normal flow of electricity can be ensured. A control switch is installed on the surface of the charging gun 20 to control the rotation of the servo motor 19 and the release length of the cable 25.

[0056] When the charging box 3 is moved into place, the motor drives the closing plate 15 to rotate. When the charging box 3 is hung upside down, the end of the charging gun 20 faces downward. The end of the charging gun 20 is provided with an electromagnetic buckle, which can fix the charging gun 20 in the card slot 21 or on the charging port of the vehicle, or pop out of the card slot 21 or the charging port of the vehicle. When the motor opens the closing plate 15, the charging gun 20 pops out, and then the servo motor 19 drives the winding roller 23 to rotate, so that the cable 25 is released, so that the charging gun 20 is slowly lowered, so that the hanging rail 1 can be installed at a high place, allowing the charging gun 20 to automatically Put it down, the charging gun 20 is docked with the vehicle and fixed to the vehicle during charging. When charging is completed, the charging gun 20 pops out through the electromagnetic buckle, and then the servo motor 19 reels the cable 25, pulls the charging gun 20 to the outside of the reel box 18, and drives the closing plate 15 to rotate through the motor. During the rotation, the charging gun 20 is pressed back to its original position, so that the head of the charging gun 20 is inserted into the card slot 21 for fixing. Through this setting, the charging gun 20 automatically returns to its original position after charging is completed, and the charging seat 10 automatically returns to charging after returning to its original position, and there will be no problem of the charging vehicle occupying the charging box 3 for a long time after charging.

[0057] The insertion groove 21 and the head of the charging gun 20 can be adsorbed to assist the fixing process of the charging gun 20. The setting of the compression pad 16 can provide a buffer, support the outer side of the charging gun 20, and safely press it into the insertion groove 21;

[0058] When two charging boxes 3 are close to each other, the two charging boxes 3 will receive the signals transmitted by each other. The processing module processes the received information, and then controls the two charging boxes 3 to move in the same direction, find the nearest switching seat 2 5, and use the switching seat 2 5 to make way for the delivered charging box 3, so as to ensure that the delivered charging box 3 can reach the destination smoothly;

[0059] The bending setting of the charging rail 7 and the preparation rail 6 can store a large number of charging boxes 3, so that a sufficient number of switching seats 2 5 can be installed on the hanging rail 1. The charging rail 7 and the preparation rail 6 need to be set in a separate room. The position of the separation rail 8 is controlled by the reduction motor 9 to rotate and open and close, so that maintenance personnel can enter conveniently.
