By setting the limiting structure 6, it is convenient to adjust the muzzle size of the charging gun, so as to facilitate the insertion of the charging gun into the charging port, and then it is convenient to quickly unlock and lock the charging gun, and improve the convenience of using the charging gun. A shielding structure 7 is provided on the surface of the gun body 1. By setting the shielding structure 7, it is convenient to shield the charger inserted into the charging port of the car, so as to avoid rainwater dripping on the surface of the charging gun when charging outdoors in the rain, causing a short circuit between the charging gun and the car charging port, and then protecting the charging gun.

[0032] The specific arrangement and function of the limiting structure 6 and the shielding structure 7 will be described in detail below.

[0033] Reference Figure 2 - Figure 6As shown, in this embodiment: the limiting structure 6 includes two arc grooves 601, the two arc grooves 601 are respectively opened on both sides of the gun head 2, a groove 602 is opened on one side of the gun head 2, a plurality of round rods 603 are slidably inserted into the inner walls of the two arc grooves 601, one end of the plurality of round rods 603 is fixedly connected with an arc plate 604, the arc surface of the round rod 603 is sleeved with a spring 605, the two ends of the spring 605 are respectively fixedly connected with the arc plate 604 and the inner wall of the arc groove 601, the other end of the plurality of round rods 603 is fixedly connected with a connecting plate 606, the surface of the connecting plate 606 is fixedly connected with a rope 607, a wire groove 608 is opened on the surface of the gun body 1, a traction rope 609 is slidably connected to the inner wall of the wire groove 608, one end of the traction rope 609 is fixedly connected with the rope 607, the other end of the traction rope 609 is fixedly connected with a slider 610, and the surface of the slider 610 is fixedly connected with a driving plate 611. The inner wall of the wire groove 608 is provided with two guide grooves 612, and the inner walls of the two guide grooves 612 are slidably connected with guide blocks 613, and the two guide blocks 613 are fixedly connected to the two sides of the slider 610 respectively. When the slider 610 moves, it will drive the guide blocks 613 to slide along the inner wall of the guide groove 612, and the guide groove 612 can limit the moving path of the guide blocks 613, thereby preventing the slider 610 from escaping from the wire groove 608 when moving. The surface of the arc plate 604 is fixedly connected with an anti-slip strip 614, and the anti-slip strip 614 is made of rubber. The arc plate 604 will move with the help of the extension force of the spring 605, and the arc plate 604 will drive the anti-slip strip 614 to fit closely to the inner wall of the charging port, and the anti-slip strip 614 can improve the stability of the charging gun inserted into the charging port. The inner wall of the groove 602 is fixedly connected with a bracket 615, and the rope 607 slides with the inner wall of the bracket 615. The inner wall of the bracket 615 is rotatably connected with two rotating wheels 616. The rope 607 moves and slides along the inner wall of the bracket 615. When sliding, the rope 607 moves along the surface of the rotating wheel 616. The shaft 72 rotates with the help of the force of the movement of the rope 607. The bracket 615 limits the moving path of the rope 607, and the rotating wheel 616 reduces the friction of the rope 607 when it moves in the bracket 615, thereby facilitating the pulling of the rope 607.

[0034] Reference Figure 7As shown, specifically, the shielding structure 7 includes two support arms 71, which are fixedly connected to both sides of the gun body 1 respectively, and the surface of the support arm 71 is rotatably connected to the rotating shaft 72, one end of the rotating shaft 72 penetrates the support arm 71, and one end of the support arm 71 is fixedly connected to an extension plate 73, and a threaded rod 74 is threadedly penetrated on the surface of the extension plate 73, and a support plate 75 is fixedly connected to the surface of the rotating shaft 72, and a baffle 76 is fixedly connected to the side of the support plate 75 away from the rotating shaft 72. A drainage groove 77 is provided on the surface of the baffle 76, and rainwater on the surface of the baffle 76 will flow along the inner wall of the drainage groove 77, and then be discharged from both sides of the drainage groove 77. The drainage groove 77 can prevent rainwater on the surface of the baffle 76 from dripping onto the arm when the charging gun is pulled out. A sealing strip 78 is fixedly connected to one side of the baffle 76, and a cavity is provided inside the sealing strip 78. The rotation of the baffle 76 will drive the sealing strip 78 to move toward the direction of the car until the sealing strip 78 fits tightly against the surface of the car. Since the interior of the sealing strip 78 is a cavity, the sealing strip 78 will deform, thereby further improving the effect of the baffle 76 fitting against the surface of the car.

[0035] Working principle: when the charging gun needs to be used, first pull the driving plate 611. The movement of the driving plate 611 will drive the slider 610 to move. The movement of the slider 610 will slide along the inner wall of the wire groove 608. When the slider 610 moves, it will drive the guide block 613 to slide along the inner wall of the guide groove 612. The guide groove 612 can limit the movement path of the guide block 613, thereby preventing the slider 610 from escaping from the wire groove 608 when moving. When the slider 610 moves, it will drive the traction rope 609 to slide along the inner wall of the wire groove 608. The movement of the traction rope 609 will drive the rope 607 to move. The rope 607 will slide along the inner wall of the bracket 615. When the rope 607 slides, it will move along the surface of the rotating wheel 616. The rotating shaft 72 will generate the force of the rope 607 moving. The bracket 615 is rotated, and the moving path of the rope 607 is limited. The rotating wheel 616 reduces the friction of the rope 607 moving in the bracket 615, thereby facilitating the pulling of the rope 607. When the rope 607 moves, it will drive the connecting plate 606 to move. The movement of the connecting plate 606 will drive the round rod 603 to move. The movement of the round rod 603 will drive the arc plate 604 to move. When the arc plate 604 moves, the spring 605 will be compressed. At this time, the spring 605 is in a compressed state. When the arc plate 604 moves to a suitable position, the charging gun is inserted into the charging port of the car, and then the driving plate 611 is released. The arc plate 604 will move with the help of the stretching force of the spring 605, and the arc plate 604 will drive the anti-slip strip 614 to fit tightly against the inner wall of the charging port.

[0036] When the charging gun is inserted into the charging port of the car, the threaded rod 74 is rotated. The threaded rod 74 rotates and moves in the extension plate 73 with the help of the thread. The threaded rod 74 moves away from the support arm 71. When the threaded rod 74 is out of contact with the support arm 71, the extension plate 73 is rotated. The rotation of the extension plate 73 drives the rotating shaft 72 to rotate the rod. The rotation of the rotating shaft 72 drives the support plate 75 to rotate. The rotation of the support plate 75 drives the baffle 76 to rotate. The rotation of the baffle 76 drives the sealing strip 78 to move towards the direction close to the car until the sealing strip 78 fits tightly. On the surface of the car, since the interior of the sealing strip 78 is a cavity, the sealing strip 78 will be deformed, thereby further improving the effect of the baffle 76 sticking to the surface of the car. When it rains, rainwater will fall on the surface of the baffle 76. The baffle 76 is convenient for shielding the charging gun during charging, thereby preventing rainwater from dripping on the surface of the charging gun. At this time, the rainwater on the surface of the baffle 76 will flow along the inner wall of the drainage groove 77, and then be discharged from both sides of the drainage groove 77. The drainage groove 77 prevents the rainwater on the surface of the baffle 76 from dripping onto the arm when the charging gun is pulled out.
