Technical Field

[0001] This invention mainly relates to the technical field of vehicle charging ports, specifically a novel charging port structure for heavy-duty trucks. Background Technology

[0002] For new energy heavy-duty trucks, a cover structure is required at the charging port. The cover is opened during charging and closed again after charging is complete. Currently, most new energy heavy-duty trucks use simple covers, which often fail to seal properly over time, resulting in poor or no sealing. This allows water, dust, and other foreign matter to enter the charging port, leading to frequent short circuits, corrosion, and electrical malfunctions. Summary of the Invention

[0003] To address the shortcomings of current technology, this invention combines existing technology and, based on practical applications, provides a novel charging port structure for heavy-duty trucks. This novel charging port structure is simple, easy to install, easy to operate, has a long service life, and its durability can be improved when installed on the skirt panel body. It also prevents water, dust, and other foreign objects from entering the equipment and has an aesthetically pleasing appearance.

[0004] The technical solution of the present invention is as follows:

[0005] A novel charging port structure for heavy-duty trucks includes a separately fixed charging port bracket and a skirt body, wherein the skirt body is disposed at the front of the charging port bracket, and further includes:

[0006] A hinge having a fixed part and a rotating part, with a hinge shaft between the fixed part and the rotating part, and the fixed part of the hinge being fixedly installed on the inner side of the skirt panel body;

[0007] A charging port cover, one end of which is fixedly connected to the rotating part of the hinge, so that the charging port cover can rotate around the hinge axis.

[0008] A lock is installed on the charging port cover plate, and the lock can cooperate with the charging port bracket to lock the charging port cover plate when the charging port cover plate is fastened;

[0009] A sealing strip is provided on the inner side of the charging port cover, and the sealing strip can press against the opening edge of the charging port bracket when the charging port cover is fastened.

[0010] Furthermore, a buffer post is provided on the inner side of the charging port cover, and a guide hole is provided on the inner side of the opening of the charging port bracket. When the cover is fastened, the buffer post can be inserted into the guide hole.

[0011] Furthermore, the buffer post is located inside the charging port cover on the side away from the hinge axis and is detachably connected to the charging port cover.

[0012] Furthermore, the buffer column is made of rubber and has a tapered structure with a smaller front end and a larger rear end.

[0028] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0029] This embodiment provides a novel charging port structure for heavy-duty trucks, primarily for use in new energy heavy-duty trucks. (Reference) Figures 1-5 The diagram shown is a schematic diagram of the main structure of the charging port provided in this embodiment.

[0030] The charging port structure mainly includes a charging port bracket 7, a skirt body 1, a hinge 8, a charging port cover 2, a lock 3, and a sealing strip 5.

[0031] Both the charging port bracket 7 and the skirt panel body 1 are individually fixed. The charging port bracket 7 houses electrical components and has an inner cavity with a flat edge at the opening, used to cooperate with the sealing strip 5 to achieve a seal. The skirt panel body 1 is located at the front of the charging port bracket 7 and has a notch corresponding to the opening of the charging port bracket 7, where the charging port cover 2 is installed.

[0032] In this embodiment, the hinge 8 provides primary support for the charging port cover 2, and the charging port cover 2 can rotate to an opening angle of 83° via the hinge 8. Specifically, refer to... Figure 5 As shown in the figure, in this embodiment, the hinge 8 includes a fixed part 81 and a rotating part 83. A hinge shaft 82 is provided between the fixed part 81 and the rotating part 83. The rotating part 83 can rotate relative to the fixed part 81 with the hinge shaft 82 as the axis.

[0033] In one specific structure provided in this embodiment, two threaded holes are provided on the rear surface of the skirt plate body 1, and two mounting holes are provided side by side on the fixing part 81 of the hinge 8. The fixing part 81 of the hinge 8 can be fixed to the rear part of the skirt plate body 1 by two screws. In this way, the entire cover plate structure is mounted on the skirt plate body 1 by the hinge 8, which improves the durability of the structure.

[0034] In one specific structure provided in this embodiment, the rotating part 83 of the hinge 8 is a bent plate structure. A slot 84 is provided at the position of the anti-rotation rib 11 corresponding to the edge of the skirt body 1, so that the rotating part 83 can rotate freely without interference from the anti-rotation rib. When the opening angle reaches the designed 83°, the edge of the slot 84 at the rotating part 83 contacts the anti-rotation rib 11 at the edge of the skirt body 1, thereby locking it. Therefore, the structure of the anti-rotation rib 11 and the slot 84 limits the rotating part 83 to reach the designed open position. Two mounting holes are also provided side by side on the outer edge of the rotating part 83. Through these two mounting holes, the rotating part 83 can be fixedly connected to the charging port cover 2, so that the charging port cover 2 can rotate around the hinge axis 82.

[0035] An opening is provided on the side of the charging port cover 2 away from the hinge axis 82, and a lock 3 is installed in the opening. The lock 3 has a locking hook, and a baffle is provided inside the edge of the cavity of the charging port bracket 7. When the charging port cover 2 is closed, the locking hook can be rotated to the back of the baffle to lock the charging port cover 2.

[0036] To ensure the sealing of the charging port in this embodiment, a sealing strip 5 is provided on the inner side of the charging port cover 2. The sealing strip 5 surrounds both the lock 3 and the buffer post 4. The shape of the sealing strip 5 is adapted to the edge shape of the opening of the charging port bracket 7. This structure allows the sealing strip 5 to be pressed tightly onto the charging port bracket 7 when the charging port cover 2 is closed, thereby achieving a sealing effect and preventing water, dust, etc. from entering the interior of the charging port bracket 7.

[0037] In a preferred embodiment, a buffer post 4 is provided on the inner side of the charging port cover 2. A seat is provided on the inner side of the charging port cover 2, and the buffer post 4 is fixed in the seat. The buffer post 4 is a conical structure made of rubber. It is designed on the side of the charging port cover 2 away from the hinge axis 82, which can improve the feel when opening and closing, and at the same time play a buffering and guiding role.

[0038] A cylinder is fixed inside the opening of the charging port bracket 7 by screws. The inner cavity of the cylinder is a guide hole 6. The position of the guide hole 6 corresponds to the position of the buffer post 4. When the charging port cover 2 is closed, the buffer post 4 can be gradually inserted into the guide hole 6. The tapered structure of the buffer post 4 facilitates its insertion.

[0039] In this embodiment, when the car charging port is closed, the charging port cover 2 rotates around the hinge axis 82. When it is close to the closing limit position, the buffer post 4 guides it, and the sealing strip 5 contacts the charging port bracket 7. Continue to press so that the sealing strip 5 and the charging port bracket 7 are in full contact. Finally, the lock 3 is used to lock it.
