[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more features.

[0025] Please see Figures 1-4 As shown, an embodiment of this utility model provides a charging port cover with a self-locking function, including a charging port cover plate 1, a drive motor 2, a motor mounting bracket 3, a linkage transmission assembly, and a gear transmission assembly. The charging port cover plate 1 is made of carbon fiber material, which effectively reduces the product's weight. The drive motor 2 is mounted on the motor mounting bracket 3 and is connected to the charging port cover plate 1 via the linkage transmission assembly, allowing the drive motor 2 to drive the charging port cover plate 1 to reciprocate between an open and closed position, thereby opening or closing the charging port.

[0026] Specifically, such as Figures 5-7 As shown, the linkage transmission assembly in this embodiment of the present invention includes a driving linkage 4 and a driven linkage 5. One end of the driving linkage 4 is pivotally connected to the charging port cover 1, and the other end of the driving linkage 4 is pivotally connected to the motor mounting bracket 3 and is connected to the output shaft 21 of the drive motor 2 via a gear transmission assembly. One end of the driven linkage 5 is pivotally connected to the charging port cover 1, and the other end of the driven linkage 5 is rotatably sleeved on the output shaft 21 of the drive motor 2.

[0027] When the drive motor 2 rotates forward or in reverse, it drives the active connecting rod 4 to rotate upward or downward through the gear transmission assembly, thereby moving the charging port cover 1 to the open or closed position. The driven connecting rod 5 rotates accordingly to cooperate with the active connecting rod 4 to form a stable support for the charging port cover 1.

[0028] Specifically, the gear transmission assembly in this embodiment includes a drive gear 6, a first transmission gear 7, and a second transmission gear 8. The drive gear 6 is fixedly mounted on the output shaft 21 of the drive motor 2. The first transmission gear 7 is rotatably mounted on the motor mounting bracket 3 and meshes with the drive gear 6 for transmission. The second transmission gear 8 connects to the drive linkage 4 and meshes with the first transmission gear 7 for transmission. Precision transmission between the drive motor 2 and the linkage transmission assembly is achieved through multiple gears.

[0029] To ensure the overall stability of the structure, the drive motor 2 is preferably a dual-output motor with dual output shafts 21. Two sets of linkage transmission components and gear transmission components are respectively set and connected to the two output shafts 21 of the drive motor 2 to form a stable four-bar linkage transmission structure.

[0030] The drive motor 2 is a self-locking motor with a self-locking function. That is, when working, the output shaft 21 of the drive motor 2 can rotate; when not working, the output shaft 21 of the drive motor 2 cannot rotate. When the charging port cover 1 moves to the open or closed position under the drive of the drive motor 2, the drive motor 2 stops working. The gear transmission assembly and linkage transmission assembly cannot move due to the self-locking of the output shaft 21 of the drive motor 2, thereby locking the charging port cover 1 in its current position. The specific model of the self-locking motor can be selected or customized according to the required reduction ratio, output torque, voltage, and other parameters. This embodiment of the utility model does not impose excessive limitations.

[0031] Furthermore, the output shaft 21 of the drive motor 2 is also provided with a sector-shaped stop groove 22 extending circumferentially therein, and a corresponding stop protrusion 51 is provided on the driven link 5. The stop protrusion 51 is movably embedded in the sector-shaped stop groove 22. When there is relative rotation between the driven link 5 and the output shaft 21 of the drive motor 2, the stop protrusion 51 slides in the sector-shaped stop groove 22, thereby limiting the relative rotation angle between the driven link 5 and the output shaft 21 of the drive motor 2 through the stop protrusion 51 and the sector-shaped stop groove 22, providing a stop point for the forward and reverse rotation of the drive motor 2.

[0032] Furthermore, a connecting rod mounting plate 9 is installed on the back of the charging port cover 1, and both the active connecting rod 4 and the driven connecting rod 5 are pivotally connected to the connecting rod mounting plate 9. Weight-reducing grooves or holes can be opened on the connecting rod mounting plate 9, provided that the connection strength is guaranteed, to meet the product's lightweight requirements.

[0033] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this utility model. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
