They are widely deployed in various scenarios such as public parking lots, residential areas, and shopping malls.

[0003] However, in actual use, when charging, conventional charging guns are rigid and integrated, with no offset compensation between the gun head and the handle. This can cause misalignment of the charging port, scratches on the pins, and jamming due to factors such as vehicle charging port installation tolerance, vehicle parking misalignment, and cable pull.

[0034] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0035] 1. In this invention, by setting an adjustment device, when connecting for charging, the plug end is moved by moving the charging gun. After the plug end contacts and plugs into the charging port of the electric vehicle, the plug end moves inside the charging gun, so that when the charging gun deviates during plugging, the plug end always keeps the axial horizontal with the charging port of the electric vehicle, avoiding the gun shell from hitting each other hard and locking jamming caused by the plugging angle deviation.

[0036] 2. In this invention, by setting up a pulling device, when removing the charging gun, the moving ring is moved to one side, causing one side of the moving ring to squeeze the pushing plate. By rotating one side of the pushing plate in the connecting groove, the other end of the pushing plate drives the pushing ring to move outward through the transmission plate. This causes the charging gun and the plug-in end to move in opposite directions, thereby causing the plug-in end to move out of the charging port. This avoids the need to shake left and right when pulling out the charging gun, which could damage the plug-in end and affect its service life.

[0037] 3. In this invention, by setting a protective device, when the charging gun is pulled out from one side of the charging pile body, the rebound force generated by the third spring during installation causes the third spring to drive the abutment plate to move outward. The abutment plate drives the extrusion groove to move. The inclined block slides in the extrusion groove, causing the extrusion groove to drive the inclined block to move inward. This drives the transmission rod to move, and the transmission rod drives the protective plate to move, so that the two protective plates close to protect the plug groove. This prevents rainwater and dust from adhering to the terminals in the plug groove under bad weather, thereby avoiding danger during charging. Attached Figure Description

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Please see Figures 1-6The present invention provides a technical solution: a high-power charging pile suitable for electric vehicles, including a charging pile body 1, a cable 3 connected to one side of the charging pile body 1, a charging gun 2 connected to the other end of the cable 3, an installation groove 5 opened on one side of the charging gun 2, and also including a plug-in end 4 and an adjustment device 7.

[0054] The plug end 4 is movably installed in the mounting groove 5, and two plug grooves 9 are provided on one side of the plug end 4. The adjustment device 7 is installed in the mounting groove 5. The adjustment device 7 includes multiple mounting plates 701. The mounting plates 701 are installed in the mounting groove 5, and a sliding groove 705 is opened on one side of the mounting plate 701. A universal ball 706 is driven in the sliding groove 705.

[0055] Furthermore, the adjustment device 7 also includes a universal groove 714, a sliding block 710, and a hinge plate 709;

[0056] Multiple universal grooves 714 are provided on one side of the plug-in end 4, and the inner wall of the universal groove 714 is movably connected to the outer wall of the corresponding universal ball 706. The outer wall of multiple sliding blocks 710 is slidably connected to the inner wall of the corresponding sliding groove 705, and a hinge groove 713 is provided on one side of the sliding block 710. Multiple hinge plates 709 are hinged to one side of the corresponding hinge groove 713, and a hinge seat 707 is hinged to the other side of the hinge plate 709. One side of the hinge seat 707 is rotatably connected to one side of the corresponding universal ball 706.

[0057] Furthermore, the adjusting device 7 also includes a stroke groove 704, a stroke rod 708, and a stop rod 702;

[0058] Multiple stroke grooves 704 are formed on one side of the inner wall of the corresponding sliding groove 705. The outer wall of multiple stroke rods 708 is slidably connected to the inner wall of the corresponding stroke groove 704. One end of the stroke rod 708 is connected to one side of the sliding block 710. One side of multiple abutment rods 702 is connected to one side of the inner wall of the mounting groove 5. The other end of multiple abutment rods 702 is connected to the same abutment ring 703.

[0059] Furthermore, the adjusting device 7 also includes a support rod 711 and a second spring 712;

[0060] Multiple support rods 711 are connected at both ends to the inner wall of the sliding groove 705, and two sliding sleeves are embedded in the sliding block 710. The inner wall of the sliding sleeve is slidably connected to the outer wall of the support rod 711. Multiple second springs 712 are sleeved on the outer wall of the corresponding support rod 711, and the two ends of the second springs 712 are connected to one side of the sliding block 710 and one side of the inner wall of the sliding groove 705, respectively.

[0061] The specific implementation method is as follows: By setting the adjustment device 7, during connection and charging, the moving charging gun 2 drives the plug end 4 to move. After the plug end 4 contacts and plugs into the electric vehicle charging port, the sliding block 710 slides in the sliding groove 705, so that the sliding block 710 drives one side of the hinge plate 709 to move through the hinge groove 713. Therefore, the other side of the multiple hinge plates 709 can drive the universal ball 706 to move through the hinge seat 707, and the universal ball 706 rotates in the universal groove 714, so that the plug end 4 can move at multiple angles in the charging gun 2. Thus, when the charging gun 2 deviates during plugging, the plug end 4 can always maintain an axial horizontal position with the electric vehicle charging port, avoiding hard collision of the gun shell and locking jamming caused by the plugging angle deviation. By setting a second spring Spring 712 stretches and compresses the second springs 712 on both sides when the sliding block 710 moves, forcing the second springs 712 to generate a rebound force. Therefore, after the plug end 4 moves out of the charging port, the rebound force of the second spring 712 drives the sliding block 710 to reset and move. Thus, the sliding block 710 resets and moves through the hinge plate 709 and the hinge seat 707. Then, the hinge seat 707 drives the plug end 4 to reset through the universal ball 706, so that the plug end 4 and the charging gun 2 are aligned on the same axis again to facilitate subsequent plugging operations. The plug end 4 is limited by the stop rod 702 and the stop ring 703. When the plug end 4 is pushed back to the limit position by the plugging force, the tail end touches the stop ring 703, so that the stop ring 703 provides rigid support force to the plug end 4 to complete the plugging and locking.

[0062] Please see Figures 7-10 The charging gun 2 is equipped with a pulling device 6, which includes a side groove 603 and a pushing ring 602.

[0063] A side groove 603 is formed inside the charging gun 2. A plurality of connecting grooves 604 are formed on one side of the inner wall of the side groove 603. Rotating grooves 605 are formed on both sides of the inner wall of the connecting groove 604. The outer wall of the pushing ring 602 is attached to and slidably connected to the inner wall of the side groove 603. A plurality of side grooves 612 are formed on one side of the pushing ring 602. Rotating grooves 613 are formed on both sides of the inner wall of the side grooves 612.

[0064] Furthermore, the pulling device 6 also includes a moving ring 601, a rotating rod 607, a push plate 608, and a transmission plate 610;

[0065] The movable ring 601 is sleeved on the outside of the charging gun 2, and the inner wall of the movable ring 601 is slidably connected to the outer wall of the charging gun 2. The outer walls of multiple rotating rods 607 are rotatably connected to the inner walls of the corresponding rotating grooves 605. One side of multiple push plates 608 is connected to one side of the corresponding rotating rod 607. One side of multiple transmission plates 610 is hinged to one side of the corresponding push plate 608. Rotating rods 611 are connected to both sides of the transmission plates 610. The outer wall of the rotating rods 611 is rotatably connected to the inner wall of the corresponding rotating grooves 613.

[0066] Furthermore, the pulling device 6 also includes a bottom groove 606 and a first spring 609;

[0067] Multiple bottom grooves 606 are formed on one side of the inner wall of the side groove 603, and the positions of the bottom grooves 606 correspond to the positions of the connecting grooves 604. One end of multiple first springs 609 is connected to one side of the bottom groove 606, and the other end of the first springs 609 is connected to one side of the push plate 608.

[0068] The specific implementation method is as follows: By setting up the pulling device 6, when removing the charging gun 2, the moving ring 601 is moved to one side, so that one side of the moving ring 601 contacts one side of the pushing plate 608. By continuously moving, the moving ring 601 squeezes the pushing plate 608. The rotating rod 607 rotates in the rotating groove 605, so that one side of the pushing plate 608 rotates and is limited in the connecting groove 604. Therefore, the other end of the pushing plate 608 drives the transmission plate 610 to move. The rotating rods 611 on both sides of the transmission plate 610 rotate in the rotating groove 613, so that the transmission plate 610 moves through the rotating rod 607. 11 drives the push ring 602 to move outward, thus causing the charging gun 2 and the plug end 4 to move in opposite directions, thereby causing the plug end 4 to move out of the charging port. This avoids the need to shake left and right when pulling out the charging gun 2, which could damage the plug end 4 and affect its service life. When the push plate 608 rotates around the rotating rod 607, it squeezes the first spring 609, forcing the first spring 609 to generate a rebound force. Therefore, after the charging gun 2 is pulled out, the first spring 609 rebounds and drives the push plate 608 to reset, thereby driving the push ring 602 to reset and move, so that the push ring 602 retracts into the side groove 603 for easy subsequent insertion.

[0069] Please see Figures 11-12 A protective device 8 is connected to one side of the plug-in terminal 4. The protective device 8 includes a protective groove 806, a protective plate 804, and a movable groove 805.

[0070] Both protective grooves 806 are opened in the plug-in end 4, and the protective grooves 806 are connected to the plug-in groove 9. The outer walls of multiple protective plates 804 are slidably connected to the inner walls of the corresponding protective grooves 806. A transmission rod 813 is connected to one side of the protective plate 804, and an inclined block 810 is connected to the other end of the transmission rod 813. A movable groove 805 is opened in the plug-in end 4, and a through groove 812 is connected between the movable groove 805 and the protective groove 806. The outer wall of the transmission rod 813 is slidably connected to the inner wall of the through groove 812, and one end of the transmission rod 813 extends into the movable groove 805 through the through groove 812.

[0071] Furthermore, the protective device 8 also includes a stop plate 801, a fixing rod 808, and a third spring 809;

[0072] The outer wall of the abutment plate 801 is slidably connected to the inner wall of the movable groove 805, and two extrusion grooves 811 are opened on both sides of the abutment plate 801. The inner wall of the extrusion groove 811 is slidably connected to the outer wall of the corresponding inclined block 810. Two fixing grooves are opened on one side of the abutment plate 801. The outer walls of the two fixing rods 808 are slidably connected to the inner walls of the corresponding fixing grooves, and the other end of the fixing rod 808 is connected to one side of the inner wall of the movable groove 805. Two third springs 809 are sleeved on the corresponding fixing rods 808, and the two ends of the third springs 809 are respectively connected to one side of the abutment plate 801 and one side of the inner wall of the movable groove 805.

[0073] Furthermore, the protective device 8 also includes a slide groove 807 and a sliding sleeve seat 803;

[0074] Two slide grooves 807 are respectively opened on one side of the inner wall of two protective grooves 806 and connected. One side of multiple sliding sleeve seats 803 is connected to the corresponding side of the protective plate 804, and the inner wall of two sliding sleeve seats 803 on the same side is slidably connected to the same slide rod 802. The two ends of the slide rod 802 are respectively connected to one side of the inner wall of the slide groove 807.

[0075] The specific implementation method is as follows: By setting up a protective device 8, the charging gun 2 is pulled out from one side of the charging pile body 1. Then, the third spring 809 generates a rebound force when the abutment plate 801 is compressed. The third spring 809 is supported by a fixing rod 808 to prevent the third spring 809 from bending during compression and affecting its rebound effect. Then, the rebound force of the third spring 809 drives the abutment plate 801 to move outward. The abutment plate 801 drives the extrusion groove 811 to move. The inclined block 810 slides in the extrusion groove 811, causing the extrusion groove 811 to drive the inclined block 810 to move inward. This drives the transmission rod 813 to move. The transmission rod 813 drives the protective plate 804 to move, so that the two protective plates 804 close to protect the insertion groove 9. To prevent rainwater and dust from adhering to the terminals in the plug slot 9 during charging, thus avoiding danger during charging, the charging gun 2 is pressed against the abutment plate 801 on one side of the electric vehicle charging port during plugging. This causes the abutment plate 801 to move, which in turn moves the pressing groove 811. The pressing groove 811 then moves the inclined block 810, which in turn moves the transmission rod 813. The transmission rod 813 then moves the protective plate 804 to both sides, thus separating the two protective plates 804 and exposing the plug slot 9 for easy plugging. The movement of the protective plate 804 causes the sliding sleeve seat 803 to move on the outer wall of the sliding rod 802, ensuring that the sliding rod 802 supports the sliding sleeve seat 803, thereby supporting and limiting the protective plate 804 and preventing it from shifting during movement, which would affect the protective effect.

[0076] Working principle: During use, when plugging in for charging, the charging gun 2 moves the plug end 4, aligning it with the charging port. The universal ball 706 moves within the universal groove 714, and the travel rod 708 slides within the travel groove 704, causing the sliding block 710 to slide within the sliding groove 705. This allows the plug end 4 to move within the charging gun 2. When the plug end 4 is aligned with the charging port and force is applied for insertion, the charging gun 2 is prevented from being pulled apart due to excessive force. The misalignment of end 4 with the charging port causes a hard collision between the plug end 4 and the charging port, resulting in locking and jamming, affecting the plugging operation. Furthermore, during plugging, one side of the charging port presses against the abutment plate 801. As the abutment plate 801 moves, it presses against the third spring 809. The movement of the abutment plate 801 also moves the pressing groove 811, which in turn moves one side of the inclined block 810. The inclined block 810 then moves the transmission rod 813, causing the transmission rod 813 to move the protective plate 804, thus separating the two corresponding protective plates 804. The plug slot 9 is exposed to ensure that the charging port terminal is inserted into the plug slot 9. When the gun is removed after charging is completed, the moving ring 601 is moved to one side, so that the moving ring 601 presses the push plate 608. The other side of the push plate 608 drives the transmission plate 610 to move. The transmission plate 610 drives the push ring 602 to move outward and contact the charging port. By continuously moving the push ring 602, the charging gun 2 moves in the opposite direction. Therefore, the charging gun 2 drives the plug end 4 to separate from the charging port, avoiding the need to shake when removing the gun, which may damage the plug end 4 and affect its service life. After the plug end 4 is separated from the charging port, the rebound force of the third spring 809 drives the abutment plate 801 to reset. The abutment plate 801 drives the inclined block 810 to reset through the pressing groove 811. Therefore, the inclined block 810 drives the transmission rod 813 to reset, so that the transmission rod 813 drives the protective plate 804 to re-close and protect the plug slot 9, preventing rainwater and dust from entering the plug slot 9 and affecting the contact effect when moving the charging gun 2.
