[0025] like Figures 1 to 5 As shown, a specific embodiment of the utility model provides a waterproof charging gun, including a charging gun body 1, a moving mechanism is arranged inside the charging gun body 1, the moving mechanism includes a motor 16, a rotating column 9 and a connecting plate 5, the motor 16 is used to drive the connecting plate 5 to move horizontally, the rotating column 9 is fixedly connected to one end of the connecting plate 5, a sealing cover 3 is arranged at the other end of the connecting plate 5, the sealing cover 3 is sleeved on the outside of the plug 2, a handle 6 is arranged at one end of the charging gun body 1, a control switch 19 is arranged at one end of the handle 6, and the control switch 19 is used to control the sealing cover 3 and the plug 2 to be sealed or separated.

[0026] By adopting the above technical solution, the utility model is designed with a moving mechanism. When the charging gun is removed from the charging port, the moving mechanism executes the set automatic sealing program, thereby controlling the horizontal movement and rotation of the connecting plate 5 to coordinate, so as to realize the automatic sealing of the plug 2 by the sealing cover 3, thereby avoiding the situation that the charging gun is forgotten to be inserted into the charging pile or falls to the ground after use, causing water to enter the inside of the plug 2.

[0027] Specifically, Figure 1 and Figure 2 As shown, a rubber sleeve 4 is fixedly arranged inside the sealing cover 3 , the size of the rubber sleeve 4 is adapted to the plug 2 , and the rubber sleeve 4 is interference-connected with the plug 2 .

[0028] By adopting the above technical solution, the rubber sleeve 4 can fill the gap between the plug 2 and the sealing cover 3 and provide effective sealing to prevent the entry of liquid, gas or dust, and can effectively prevent water from entering and maintain a dry environment inside the plug 2.

[0029] Specifically, Figure 3 and Figure 4 As shown, a connecting plate 5 is provided at one end of the sealing cover 3 , and the upper end of the connecting plate 5 is movably arranged inside the charging gun body 1 .

[0030] By adopting the above technical solution, through the movement and rotation of the upper end of the connecting plate 5, the sealing cover 3 can complete horizontal movement first and then swing to achieve automatic separation, or the sealing cover 3 can complete swinging first and then horizontal movement to achieve automatic sealing.

[0031] Specifically, Figure 4 and Figure 5 As shown, a rotating shaft 11 is provided at both ends of the rotating column 9, the rotating shaft 11 is rotatably arranged inside a slider 12, the slider 12 is slidably arranged inside a slide rail 13, the slide rail 13 is arranged on both sides of the active cavity 8, a fixed frame 15 is provided on one side of the slider 12, a motor 16 is provided at one end of the fixed frame 15, a second gear 17 is provided at one end of the motor 16, the second gear 17 is meshed and connected with a second rack 18, and the second rack 18 is arranged at the bottom of the active cavity 8.

[0032] By adopting the above technical solution, the motor 16 drives the connecting plate 5 to move horizontally, so that the sealing cover 3 is detached from the outside of the plug 2. In order not to affect the use of the charging gun, the rotating column 9 rotates on the first rack 14 under the drive of the motor 16, so that the connecting plate 5 swings greatly, thereby moving the sealing cover 3 that has been detached horizontally downward to the lower end of the charging gun body 1.

[0033] Specifically, Figure 3 and Figure 4As shown, the outer side of the rotating column 9 is symmetrically provided with a first gear 10, which is meshed and connected with a first rack 14. The first rack 14 is arranged at the bottom of the movable cavity 8. A slide groove is provided at the bottom of the charging gun body 1, and the size of the slide groove is adapted to the connecting plate 5. When the connecting plate 5 is rotated and retracted, the bottom end is fitted with the bottom of the movable cavity 8, and the first gear 10 is detached from the upper end of the first rack 14.

[0034] By adopting the above technical solution, during the automatic sealing process of the plug 2, the size between the first gear 10 and the first rack 14 needs to be strictly calculated and adapted. When the first gear 10 is separated from the first rack 14, the rotating column 9 stops rotating and the connecting plate 5 is in a horizontal position. At this time, one end of the connecting plate 5 is attached to the bottom of the active cavity 8. With the continued operation of the motor 16, the connecting plate 5 slides along the bottom of the active cavity 8 by an end distance, so that the sealing cover 3 moves horizontally and is mounted on the outside of the plug 2.

[0035] Specifically, Figure 1 As shown, a guide plate 7 is arranged on the outer side of the charging gun body 1 , and the lower end of the guide plate 7 is protrudingly arranged at the bottom of the charging gun body 1 .

[0036] By adopting the above technical solution, the lower end of the guide plate 7 is protruding. On rainy days, a small amount of rainwater is inevitably sprinkled on the outside of the charging gun. The guide plate 7 plays a role in guiding the rainwater, preventing rainwater from flowing down the lower end surface of the charging gun body 1.

[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
