[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0025] The vehicle charger structure in this embodiment of the utility model is as follows: Figures 1 to 5As shown, it includes a charger body 1 and a cover 2; the charger body 1 has a charging port 11 at its front end, allowing users to insert the power cord of an electronic device into the charging port 11 for charging; the charger body 1 has an outwardly protruding limiting flange 12 on its outer periphery at its front end; the cover 2 includes a sleeve portion 21 that fits onto the front of the charger body 1, a cover portion 22 for closing the charging port 11, and a connecting portion 23 that connects the sleeve portion 21 and the cover portion 22; the sleeve portion 21 is made of soft rubber and is adapted to fit against the rear end face of the limiting flange 12; the rear end face of the limiting flange 12 has a mounting buckle 13 that extends rearward and passes through the sleeve portion 21; in this embodiment, the cover portion 22 covers the charging port 11. The charging port 11 is covered at the front of the charger body 1, thus providing waterproof and dustproof protection. The structure of the sleeve part 21 connecting to the charger body 1 and the connecting part 23 connecting to the cover part 22 prevents the cover 2 from falling off. During installation and use, the mounting buckle 13 quickly engages with the mounting part, facilitating the installation and fixation of the vehicle charger. The sleeve part 21 can be pressed between the limiting flange 12 and the mounting surface, forming an effective waterproof and dustproof barrier to prevent water and dust from entering through the mounting hole. Furthermore, since the mounting buckle 13 passes through the sleeve part 21, it can limit the sleeve part 21, making it difficult for the cover 2 to fall off the vehicle charger.

[0026] Furthermore, the socket 21 is designed as a sheet with both its front and rear sides being flat. The socket 21 has a through hole 211 for the mounting buckle 13 to pass through. The flat design allows the front side of the socket 21 to fit tightly against the rear end face of the limiting flange 12 and the rear side of the socket 21 to fit tightly against the mounting surface, thereby helping to form an effective seal, preventing the intrusion of moisture and dust, and thus improving the waterproof and dustproof performance.

[0027] like Figure 1 As shown, the cover 22 is provided with a plug 24 suitable for insertion into the charging port 11. When the cover 22 is placed on the front end of the charger body 1, the plug 24 is inserted into the charging port 11. In this way, the plug 24 is inserted into the charging port 11, thereby strengthening the limiting effect of the cover 22 and enhancing the protective effect.

[0028] To enhance the limiting effect of the cover 22, a fixing buckle 14 is provided at the front end of the charger body 1. A fixing hole 20 is provided at the edge of the cover 22 corresponding to the fixing buckle 14. After the cover 22 closes the charging port 11, the cover 22 is fixed by the cooperation of the fixing buckle 14 and the fixing hole 20. By fixing the cover 22 with the cooperation of the fixing buckle 14 and the fixing hole 20, the cover can be effectively prevented from being accidentally opened or loosened during use, thereby ensuring that the charging port 11 always remains closed. Moreover, the method of fastening the fixing buckle 14 with the fixing hole 20 is intuitive and convenient to operate, and the structure is simple and easy to manufacture.

[0029] See Figure 1 and Figure 5 As shown, in order to facilitate the opening of the cap 22, an outwardly protruding pull tab 25 is provided on the edge of the cap 22, and the fixing hole 20 is provided on the pull tab 25. When opening the cap 22, the pull tab 25 serves as a clear point of force application, allowing the user to apply force more easily when opening the cap 22, avoiding the inconvenience or risk of finger slippage that may be caused by directly grasping the cap with fingers; moreover, by pulling the pull tab 25, the fixing hole 20 can be deformed and enlarged, making it easier to unfasten from the fixing buckle 14, reducing the difficulty of operation.

[0030] In this embodiment, the sleeve part 21, the cover part 22 and the connecting part 23 are made of rubber in one piece and are produced directly by injection molding. This makes processing convenient and the one-piece molding method can reduce the number of parts, thereby reducing the complexity of the structure and potential failure points.

[0031] like Figures 1 to 3 As shown, the edge of the socket 21 is flush with the outer edge of the limiting flange 12. The flush design makes the product look neater and improves the overall visual effect.

[0032] As shown in the figure Figure 4 and Figure 5 As shown, in order to facilitate the assembly of the vehicle charger, an opening 16 is further provided on the side wall of the charger body 1 for the circuit module 15 to be installed. A limiting cover 17 is provided at the opening 16. During assembly, the circuit module 15 is installed into the charger body 1 through the opening 16, and then the limiting cover 17 is installed at the opening 16 to limit the circuit module 15 and ensure the integrity of the appearance of the vehicle charger.

[0033] like Figure 5As shown, the rear end of the charger body 1 is provided with a slot 18 that communicates with the opening 16, and the opening of the slot 18 and the opening of the opening 16 face the same direction. A cable protector 3 is fitted into the slot 18. The cable protector 3 is quickly and reliably positioned by engaging with the slot 18. The limiting cover 17 further limits and blocks the cable protector 3. This arrangement simplifies the structure and eliminates the need for additional limiting components to fix the cable protector 3. The wires connecting the circuit module 15 and the external circuit pass through the inside of the cable protector 3. The cable protector 3 is made of rubber.

[0034] To reliably fix the limiting cover 17 at the opening 16, one end of the opening 16 is provided with an insertion hole 161 and the other end is provided with a bayonet 162. One end of the limiting cover 17 is provided with an insertion block 171 that is inserted into the insertion hole 161, and the other end is provided with a locking block 172 that is suitable for engaging with the bayonet 162. The opening of the opening 16 is provided with a guide groove 163 at a position corresponding to the bayonet 162. The locking block 172 is suitable for engaging into the bayonet 162 through the guide groove 163. When installing the limiting cover 17, first insert the insertion block 171 into the insertion hole 161, and then flip the limiting cover 17 over to close it, so that the locking block 172 slides through the guide groove 163 and engages into the bayonet 162, thereby completing the fixation of the limiting cover 17.

[0035] As a modified implementation, the limiting cover 17 can also be fixed to the charger body 1 by screws; or, the limiting cover 17 can be fixedly connected to the charger body 1 by a buckle to ensure the reliability of the installation of the limiting cover 17.

[0036] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
