The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides a protective cover for an electric vehicle charging port, such as... Figure 1-4 As shown, the electric vehicle charging port protective cover includes: a cover 1 for protecting the electric vehicle charging port; an annular sealing ring 14 installed on one side of the cover 1 for waterproof sealing between the cover 1 and the vehicle charging port; and an adsorption fixing mechanism installed on the cover 1 for adsorbing and fixing the cover 1 to the vehicle charging port.

[0018] In this embodiment, by installing an adsorption fixing mechanism on the cover 1, the protective cover is firmly fixed around the charging port by utilizing the adsorption characteristics of the adsorption fixing mechanism, preventing it from falling off or shifting. This design can effectively protect the charging port from dust, rain, foreign objects and other damage, extending the service life of the charging port. It can also facilitate quick installation and removal by users. Moreover, the adsorption fixing method does not require additional tools or complicated operations, improving the ease of use. The overall structure is simple and practical, and has high practical value.

[0019] In a further preferred embodiment of this utility model, the cover 1 is provided with a first clearance opening 3 and a second clearance opening 4 for the charging gun to pass through. The adsorption and fixing mechanism includes: a groove 2 installed on one side of the cover 1 and a vacuum suction cup 6 installed on the inner wall of the groove 2; a connecting pipe 7 installed on the vacuum suction cup 6 and extending into the interior of the cover 1; an annular pipe 8 installed at one end of the connecting pipe 7; a negative pressure pump 9 fixedly installed on the inner wall of the cover 1, the negative pressure pump 9 being a HIBLOW HP-20; a negative pressure pipe 10 disposed at the air inlet end of the negative pressure pump 9 and connected to the annular pipe 8; and a one-way valve 11 disposed on the negative pressure pipe 10.

[0020] In this embodiment, a vacuum suction cup 6 is installed on the inner wall of the groove 2. It is connected to an annular tube 8 through a connecting pipe 7. The annular tube 8 is then connected to the air inlet of a negative pressure pump 9 fixed to the inner wall of the cover 1 through a negative pressure pipe 10. A one-way valve 11 is provided on the negative pressure pipe 10 to prevent gas backflow. When in use, after the negative pressure pump 9 is started, it draws air from the vacuum suction cup 6 through the negative pressure pipe 10 and the annular tube 8, so that it forms a negative pressure and adsorbs onto the surface around the charging port, thereby firmly fixing the protective cover. The one-way valve 11 ensures that the negative pressure environment is stable and prevents outside air from entering and causing adsorption failure. This design forms a vacuum adsorption through active suction. Compared with traditional magnetic or adhesive methods, the fixation is more secure and less affected by environmental factors (such as temperature and humidity).

[0021] In a further preferred embodiment of the present invention, a pressure relief pipe 12 is provided on the annular pipe 8, a pressure relief valve 13 is provided on the pressure relief pipe 12, and an insertion port 5 is provided on one side of the cover 1.

[0022] In this embodiment, a pressure relief pipe 12 and a pressure relief valve 13 are provided on the annular pipe 8, and an annular sealing ring 14 is provided on one side of the cover 1. In use, the negative pressure pump 9 draws air from the vacuum suction cup 6 through the negative pressure pipe 10 and the annular pipe 8 to form a negative pressure adsorption. When it is necessary to remove the protective cover, the pressure relief valve 13 can be opened to release the negative pressure in the vacuum suction cup 6 through the pressure relief pipe 12, so that the protective cover can be easily removed from the surface of the charging port, avoiding damage caused by forced pulling. The annular sealing ring 14 further enhances the sealing between the cover 1 and the surface around the charging port, preventing rainwater and foreign objects from entering.

[0023] In a further preferred embodiment of the present invention, a protective cover 15 is provided on one side of the cover 1, and a sealing gasket 16 is provided on one side of the protective cover 15.

[0024] In this embodiment, the protective cover 15 can protect the charging gun from rain, and the sealing gasket 16 can improve the sealing between the protective cover 15 and the cover 1, preventing rainwater from flowing into the cover 1 through the second clearance opening 4.

[0025] In a further preferred embodiment of the present invention, a plug plate 17 is fixedly installed on the protective cover 15, the plug plate 17 is adapted to the plug port 5, and an arc-shaped slot 18 is provided on the plug plate 17.

[0026] In this embodiment, the insert plate 17 and the arc-shaped slot 18, together with the locking mechanism, facilitate the installation and disassembly of the cover 15.

[0027] In a further preferred embodiment of the present invention, a locking mechanism is installed on the inner wall of the cover 1. The locking mechanism includes: a vertical plate 19 fixedly installed on the inner wall of the cover 1; a rotating shaft 20 rotatably installed on the vertical plate 19; and an arc-shaped locking plate 21 fixedly installed on the rotating shaft 20 and adapted to the arc-shaped locking groove 18.

[0028] In this embodiment, the servo motor 22, the driving gear 23 and the driven gear 24 can drive the rotating shaft 20 and the arc-shaped card plate 21 to rotate, thereby connecting or separating the arc-shaped card plate 21 from the arc-shaped card slot 18, thereby locking the protective cover 15.

[0029] In a further preferred embodiment of the present invention, a servo motor 22 is fixedly installed on one side of the vertical plate 19. The servo motor 22 is of model ECMA-C20807RS. The output shaft of the servo motor 22 is equipped with a drive gear 23 through a coupling. A driven gear 24 is fixedly sleeved on the rotating shaft 20. The drive gear 23 meshes with the driven gear 24.

[0030] In this embodiment, the servo motor 22, the driving gear 23 and the driven gear 24 can drive the rotating shaft 20 and the arc-shaped card plate 21 to rotate, thereby connecting or separating the arc-shaped card plate 21 from the arc-shaped card slot 18, thereby locking the protective cover 15.

[0031] In a further preferred embodiment of the present invention, a lithium battery 25 is provided on the bottom inner wall of the cover 1, a charging interface 26 is provided at the bottom of the cover 1, and a controller is provided on the cover 1, the controller model being iTC808FAT-3.

[0032] In this embodiment, the device can be operated and controlled by the controller, powered by the lithium battery 25, and charged by an external charging cable connected to the charging interface 26.

[0033] In summary, compared with related technologies, this protective cover can not only protect the charging port of electric vehicles, but also the charging head. It is also easy to install and remove, and facilitates assembly and disassembly.
