[0030] The specific configuration and function of the protective structure 5 and the sealing structure 6 will be described in detail below.

[0031] Reference Figure 2 and Figure 3 and Figure 4 As shown, in this embodiment: the protective structure 5 includes a support frame 501, the support frame 501 is fixedly connected to the surface of the liquid-cooled charging gun body 1, and two rectangular sleeves 502 are slidably connected to the surface of the support frame 501. The two rectangular sleeves 502 are fixedly connected to the side close to the transmission line 2, and the driving arm 503 is fixedly connected to the end away from the rectangular sleeve 502. The protective plate 504 is fixedly connected, and two bolts 505 are slidably penetrated on the surface of the two protective plates 504, and nuts 506 are threaded on the surfaces of the two bolts 505. A latch 507 is slidably inserted on the surface of the rectangular sleeve 502, and a plurality of round holes 508 are provided on the surface of the support frame 501. The size of the latch 507 matches the size of the round hole 508, and the latch 507 is inserted into the round hole 508. The latch 507 reaches the position of limiting the rectangular sleeve 502, thereby limiting the position of the protective plate 504, thereby limiting the protective plate 504. The latch 507 reaches the position of limiting the protective plate 504, thereby facilitating the use of the bolt 505 and the nut 506 to fix the protective plate 504. A first spring 509 is sleeved on the surface of the latch 507, and the two ends of the first spring 509 are respectively fixedly connected to the latch 507 and the rectangular sleeve 502. The latch 507 is inserted into the round hole 508 with the help of the contraction force of the spring, and the spring improves the stability of the latch 507 inserted into the round hole 508. A protective pad 510 is fixedly connected to one side of the protective plate 504 close to the transmission line 2. The protective pad 510 is made of rubber. The protective plate 504 will drive the protective pad 510 to fit the surface of the transmission line 2. The protective pad 510 is made of rubber, thereby avoiding the effect of the protective plate 504 being too hard to limit the transmission line 2, causing indentations on the surface of the transmission line 2 and causing damage.

[0032] Reference Figure 5 As shown, specifically, the sealing structure 6 includes a frame 61, the frame 61 is fixedly connected to the surface of the liquid-cooled charging gun body 1, the inner wall of the frame 61 is fixedly connected to a second spring 62, the other end of the second spring 62 is fixedly connected to a rectangular plate 63, the surface of the rectangular plate 63 is fixedly connected to a round rod 64, the end of the round rod 64 away from the frame 61 is fixedly connected to a sealing cover 65, and the sealing cover 65 is slidably connected to the surface of the liquid-cooled charging gun body 1. Slide grooves 66 are provided on both sides of the inner wall of the frame 61, and a slider 67 is slidably connected to the inner wall of the slide groove 66. The slider 67 is fixedly connected to the surface of the rectangular plate 63. When the rectangular plate 63 moves, it will drive the slider 67 to slide in the slide groove 66. The slide groove 66 has the effect of limiting the moving path of the slider 67, thereby preventing the rectangular plate 63 from falling out of the slide rail. A sealing ring 68 is fixedly connected to the surface of the sealing cover 65, and the inner wall of the sealing ring 68 is a cavity. The sealing cover 65 will drive the sealing ring 68 to fit tightly to the surface of the car. The sealing ring 68 is deformed due to extrusion, thereby further improving the fit of the sealing cover 65 to the surface of the car.

[0033] Working principle: when it is necessary to connect the transmission line 2 with the liquid-cooled charging gun body 1, first pull the pin 507. The pin 507 will slide in the rectangular sleeve 502 and come out of the round hole 508 when it moves. The pin 507 will stretch the spring when it moves, and pull the two protective plates 504 away from each other. The movement of the protective plates 504 will drive the driving arm 503 to move. The movement of the driving arm 503 will drive the rectangular sleeve 502 to slide on the surface of the support frame 501. When the rectangular sleeve 502 moves to a suitable position, release the pin 507. The pin 507 will be inserted into the round hole 508 with the help of the contraction force of the spring, and then the transmission line 2 is connected to the surface of the liquid-cooled charging gun body 1. Pull the pin 507 again to make the pin 507 come out of the round hole 508, and then pull the two protective plates 504 towards each other. The protective plates 504 will move closer to the transmission line 2. 506, and then the nut 506 is screwed onto the surface of the bolt 505. The bolt 505 and the nut 506 will move on the surface of the bolt 505, and the bolt 505 and the nut 506 will make the two protective plates 504 gradually fit more closely, so that the two protective plates 504 are tightly limited on the surface of the transmission line 2, thereby limiting the position of the transmission line 2.

[0034] When the liquid-cooled charging gun body 1 is inserted into the interface of the car for charging, the sealing cover 65 will drive the sealing ring 68 to fit the surface of the car when the connector of the liquid-cooled charging gun body 1 contacts the interface, and the plug 3 continues to be pushed, and the plug 3 is gradually inserted into the interface. At this time, the sealing cover 65 will slide along the surface of the liquid-cooled charging gun body 1, and the sealing cover 65 will drive the round rod 64 to move when it moves. The movement of the round rod 64 will drive the rectangular plate 63 to slide in the frame 61, and the rectangular plate 63 will drive the slider 67 to slide in the slide groove 66 when it moves, and the slide groove 66 reaches the movement path of the slider 67. , thereby preventing the rectangular plate 63 from falling out of the slide rail. When the rectangular plate 63 slides in the frame 61, it will squeeze the second spring 62, and the second spring 62 will gradually shrink. When the plug 3 is fully inserted into the socket, the sealing cover 65 will drive the sealing ring 68 to fit tightly against the surface of the car. The sealing ring 68 will deform due to the squeezing, thereby further improving the fit of the sealing cover 65 to the surface of the car. By sealing the connection between the plug 3 and the socket with the sealing cover 65, it is avoided that rainwater drips onto the connection during charging, causing rainwater to enter the connection.
