[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0025] like Figure 1-4 As shown, a car charging port waterproof structure includes:

[0026] The base 1 has a built-in cavity, in which a charging terminal 14 is arranged;

[0027] A cover plate 3 is rotatably disposed on the base 1 and cooperates with the charging terminal 14, and a rotating shaft 24 rotatably connected to the base 1 is disposed on the cover plate 3;

[0028] A transmission unit 2, which is disposed on the base 1 and cooperates with the rotating shaft 24, and the transmission unit 2 drives the cover plate 3 located on the base 1 to flip over;

[0029] The folding curtain 4 has one end clamped on the base 1, and a support block 43 matched with the cover plate 3 is provided at the other end, and a pull rod 44 is symmetrically provided on the support block 43, a spring 45 is provided between the pull rod 44 and the support block 43, and a clamping plate 31 matched with the pull rod 44 is provided on the cover plate 3.

[0030] Specifically, the base 1 has a built-in cavity, in which a charging terminal 14 is arranged, a cover plate 3, which is rotatably arranged on the base 1 and cooperates with the charging terminal 14, a rotating shaft 24 rotatably connected to the base 1 is arranged on the cover plate 3, a transmission unit 2 is arranged on the base 1, and cooperates with the rotating shaft 24, the transmission unit 2 drives the cover plate 3 to flip on the base 1, one end of the folding curtain 4 is clamped on the base 1, and a support that cooperates with the cover plate 3 is arranged at the other end. Block 43, pull rods 44 are symmetrically arranged on the support block 43, a spring 45 is arranged between the pull rod 44 and the support block 43, and a card plate 31 matched with the pull rod 44 is arranged on the cover plate 3. The cover plate 3 is driven to flip on the base 1 by the transmission unit 2, so that the charging terminal 14 in the built-in cavity is exposed. During the flipping process of the cover plate 3, the folding curtains 4 on both sides of the base 1 are extended to cover the two sides of the charging terminal 14, thereby reducing the damage caused by rainwater entering the charging port on rainy days.

[0031] As an embodiment further provided by the present invention, a receiving groove 11 is symmetrically arranged on the base 1, and a clamping block 41 cooperating with the folding curtain 4 is arranged in the receiving groove 11. The receiving groove 11 cooperates with the supporting block 43. When the cover plate 3 is in contact with the base 1, the folding curtain 4 is folded into the receiving groove 11, and the supporting block 43 is also placed in the receiving groove 11.

[0032] As a further embodiment of the present invention, a top block 42 that fits with the card block 41 is slidably provided on the base 1 , and pressing the top block 42 can push out the card block 41 in the built-in cavity, thereby facilitating the disassembly, assembly and replacement of the folding curtain 4 .

[0033] As an embodiment further provided by the present invention, a limit block 441 and a pressing end 442 are sequentially provided at one end of the pull rod 44. The limit block 441 is square and slides in the support block 43, while the pressing end 442 is clamped on the card plate 31. The limit block 441 limits the sliding direction of the pull rod 44 so that it can only slide in the support block 43, while the pressing end 442 is clamped on the card plate 31 to provide certain support for the support block 43, and the side of the support block 43 that is not matched with the folding curtain 4 is clamped in the cover plate 3.

[0034] As an embodiment further provided by the present invention, the transmission unit 2 includes a motor 21, a support plate 25 and a driven wheel 23 arranged on the rotating shaft 24. The motor 21 is arranged on the support plate 25, and the support plate 25 is clamped on the base 1. A slide groove 16 is opened on the base 1, and the support plate 25 is clamped in the slide groove 16. The output end of the motor 21 is provided with a driving wheel 22 meshing with the driven wheel 23. The model of the motor 21 is MHMF042L1U2M2. The driving wheel 22 and the driven wheel 23 are both bevel gears. The bevel gear transmission has a relatively large tooth surface width and a strong load-bearing capacity. It can improve the support effect on the cover plate 3. When the electric vehicle needs to be charged, the motor 21 drives the driving wheel 22 to rotate, thereby linking the driven wheel 23 to flip the cover plate 3 on the rotating shaft 24, so that the charging end 14 is exposed.

[0035] As an embodiment further provided by the present invention, a drainage groove 12 is provided on the base 1 and is connected to the built-in cavity. The drainage groove 12 is provided with a slot 13 that cooperates with the cover plate 3. When rainwater enters the built-in cavity, the charging port is inclined at 15° on the vehicle body 5, so that the rainwater in the built-in cavity slides along the wall to the drainage groove 12, and then flows out along the drainage groove 12.

[0036] As a further embodiment of the present invention, a sealing groove 15 is provided on the base 1, and a soft glue 151 is provided in the sealing groove 15. The soft glue 151 is conical, and an arc portion 152 is provided at the tip of the cone. The soft glue 151 is clamped in the sealing groove 15. When the base 1 is connected to the car, the soft glue 151 improves the sealing between the two. During car washing or driving in rainy days, the cover plate 3 is squeezed (such as Figure 5 As shown), under such extrusion, the soft rubber 151 will be deformed, and the fitting surface between the arc-shaped portion 152 and the vehicle sheet metal will be increased, further improving the sealing effect.

[0037] Working principle: First, when the electric vehicle is parked outdoors for charging, the motor 21 drives the active wheel 22 to rotate in conjunction with the driven wheel 23, so as to control the cover plate 3 located on the base 1 to flip away from the charging terminal 14, and at the same time, the folding curtain 4 located in the receiving groove 11 is unfolded in a fan shape to block the two ends of the charging port, so as to reduce the rainwater from entering the charging port on rainy days, and further block the direct sunlight on the charging gun and the charging port in sunny weather, thereby reducing the heat increase during charging. If rainwater is in the receiving groove 11, it will flow out from the leakage groove 12 to the charging port. When the folding curtain 4 is used for a long time or is not needed, the pull rod 44 can be pulled or the pressing end 442 can be contacted to disengage the support block 43 from the card plate 31, and the top block 42 can be pressed to push out the card block 41 located in the receiving groove 11, so as to facilitate the replacement of the damaged folding curtain 4, or remove the folding curtain 4, thereby improving the use experience of the charging port.

[0038] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0039] The technical solutions in the above embodiments have clearly and completely described the contents of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
