[0035] The following further describes the present utility model in detail with reference to the accompanying drawings:

[0036] Example

[0037] As mentioned in the background technology, the hinge device of the current automobile charging port cover has the following problems. For example, after the charging port cover is opened, the hinge device lacks a limiting device, which causes the charging port cover to shake when plugging and unplugging the charging gun. This not only affects the user experience but also may bring safety hazards. Therefore, it is necessary to find a new structure to solve this problem.

[0038] In order to solve the above technical problems, the embodiments of the present utility model provide a hinge device and a car that prevents the car charging port cover from shaking after opening.

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a hinge device for preventing the cover of a car charging port from shaking after opening, including a hinge device assembly 1, which is arranged on the rear side outer panel 13 of the car, wherein the hinge device assembly 1 includes a hinge fixing plate 2, a hinge rotating arm 3 and a hinge rotating shaft 4, and the hinge rotating shaft 4 passes through the hinge rotating arm 3 and the hinge fixing plate 2.

[0040] In this embodiment, Figures 2 - 5 As shown, a second bolt fixing hole 8 matching the diameter of the screw 6 is opened on the hinge rotating shaft 4, and a corresponding first bolt fixing hole 7 is opened on the hinge rotating arm 3. Then the screw 6 is passed through the first bolt fixing hole 7 and the second bolt fixing hole 8. This fixing method can firmly connect the hinge rotating arm 3 to the hinge rotating shaft 4, and the hinge rotating arm 3 can rotate around the hinge rotating shaft 4.

[0041] In this embodiment, a positioning slot 10 is provided on the hinge fixing plate 2, and a limiting column 9 is provided on the hinge rotating arm 3. The limiting column 9 and the positioning slot 10 can be engaged and disengaged when the charging port cover is opened and closed. By engaging and disengaging the limiting column 9 and the positioning slot 10, it can be ensured that the charging port cover can be accurately closed to the specified position every time, and at the same time, the stability of the charging port cover during the opening and closing process is improved, and the risk of shaking and dislocation is reduced.

[0042] In this embodiment, the hinge fixing plate 2 includes a base plate, both ends of the base plate of the hinge fixing plate 2 are provided with a first spring slot 11, and both ends of the hinge rotating shaft 4 are provided with a second spring slot 12. The first spring slot 11 and the second spring slot 12 jointly fix the spring 5.

[0043] In this embodiment, second spring slots 12 are provided at both ends of the hinge rotating shaft 4 , and the second bolt fixing hole 8 is located inside the second spring slots 12 .

[0044] The present utility model will be further explained and illustrated below in combination with a set of examples and drawings:

[0045] As Figure 1 shown, the hinge device assembly 1 can be fixed to the outer panel 13 of the rear side wall of the vehicle, the fender of the vehicle, and the front and rear bumpers.

[0046] As Figures 2 - 5 shown, the first spring slot 11 and the second spring slot 12 jointly fix the spring 5. The hinge rotating arm 3 rotates around the hinge rotating shaft 4 under the drive of the spring 5 to realize the opening and closing of the charging port cover. By fixing the two ends of the spring 5 in the first spring slot 11 and the second spring slot 12 respectively, it can be ensured that the spring 5 can expand and contract in a predetermined direction and degree when subjected to an external force, thereby driving the movement of the hinge rotating arm 3, and further driving the opening and closing of the charging port cover.

[0047] Another example is Figure 4 shown, the limit post 9 is a conical limit post. The design of the conical head helps to reduce the resistance generated during the insertion or extraction of the limit post 9 into the positioning slot 10, making the mechanical operation smoother, reducing wear and failures caused by excessive resistance. In the hinge device of the vehicle charging port cover, the conical limit post can cooperate with the positioning slot 10 to realize the stable opening and closing of the charging port cover. Moreover, by adjusting the size and shape of the conical limit post, the accuracy and reliability of the charging port cover under different usage conditions can be ensured.

[0048] There are gaps between the left and right sides of the limit post 9 and the two sides of the positioning slot 10, and the width of the gap is 0.1 mm. The limit post 9 maintains a certain distance from the positioning slot 10 during the opening and closing of the charging port cover, which can avoid direct contact and friction between the two, helping to reduce wear, noise, and energy loss caused by friction, improving the durability and service life of mechanical components. In addition, the appropriate gap enables the limit post 9 to enter and exit the positioning slot 10 more smoothly, without affecting the opening and closing actions of the charging port cover due to being too tight or too loose, improving the user experience and making the operation easier and smoother.

[0049] Working principle

[0050] As Figure 6 and Figure 7 shown, when it is necessary to open the vehicle charging port cover, the external force applied by the user will overcome the pre-tightening force of the spring 5, causing the hinge rotating arm 3 to start rotating. As the rotation progresses, the spring 5 is gradually stretched until the charging port cover reaches the fully open position. At this time, the limit post 9 snaps into the positioning slot 10, and the insertion and cooperation of the limit post 9 and the positioning slot 10 play a role in limiting the left and right positions, and the charging port cover is in the open state.

[0051] When it is necessary to close the vehicle charging port cover, the user applies a reverse force. At this time, the restoring force of the spring 5 drives the hinge rotating arm 3 to rotate in the reverse direction, pulling the charging port cover back to the closed position. During this process, the potential energy of the spring 5 is gradually released until the charging port cover is completely closed and locked. During this process, the limit post 9 gradually separates from the positioning card slot 10 until it completely disengages from the card slot. At this time, the charging port cover is firmly fixed in the closed position.

[0052] In summary, this embodiment provides a vehicle charging port cover hinge device with stable structure. By the cooperation of the limit post 9 and the positioning card slot 10, and taking the hinge rotating shaft 4 as the first linear limit reference and the cooperation of the conical limit post 9 and the positioning card slot 10 as the second limit reference, the two form a plane, which better solves the problem of the charging port cover shaking left and right after opening, improves the overall texture of the product, reduces the resistance and noise generated by friction, and enhances the user experience.

[0053] This embodiment also provides a vehicle with a hinge device for preventing the vehicle charging port cover from shaking after opening. This vehicle adopts a hinge device for preventing the vehicle charging port cover from shaking after opening. Its charging port cover can remain stable and no longer shake after opening, which is convenient for the user to perform charging operations, effectively preventing potential safety hazards and inconveniences caused by shaking or position deviation. It not only improves the charging convenience and the quality sense of the vehicle, but also reduces the maintenance cost.

[0054] Upon reading the above description, many embodiments and many applications other than the provided examples will be obvious to those skilled in the art. Therefore, the scope of this teaching should not be determined with reference to the above description, but should be determined with reference to the full scope of the foregoing claims and the equivalents of those claims.
