[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a charging port structure that can be installed on a vehicle frame and is used to connect to an external power source to charge a battery pack in the vehicle frame.

[0031] The charging port structure includes a mounting plate 1, a charging interface 2, a charging port cover 3, and an elastic latch 4. The mounting plate 1 is mounted on the vehicle frame, and the charging interface 2 is mounted on the mounting plate 1 and electrically connected to the battery pack, so that an external power source can charge the battery pack through the charging interface 2. Optionally, the mounting plate 1 can be movably mounted on the vehicle frame, thereby adjusting the position of the charging interface 2 and the charging port cover 3, thereby reducing the installation of the charging port structure on the vehicle frame. Specifically, a waist hole is formed on the mounting plate 1, and a connecting bolt is passed through the waist hole to connect to the vehicle frame. The position of the mounting plate 1 on the vehicle frame can be adjusted by adjusting the position of the connecting bolt in the waist hole.

[0032] When the elastic latch 4 releases the lock head 31, it can lift the charging port cover 3. In this process, the rotation angle of the charging port cover 3 is small, which avoids the charging port cover 3 from rotating too much and colliding with the vehicle body and causing damage.

[0033] Optionally, when the elastic latch 4 engages the lock head 31, the charging port cover 3 is spaced apart from the charging port 2, ensuring sufficient space between them. This prevents the charging port cover 3 from deforming and damaging the charging port 2 due to impact. Furthermore, the outer periphery of the charging port cover 3 may be curved and extended toward the side closest to the charging port 2. This edge 32 enhances the overall structural strength of the charging port cover 3 and improves its protection of the charging port 2. Furthermore, when the charging port cover 3 is positioned over the charging port 2, the edge 32 precisely conforms to the vehicle body, effectively providing a protective seal and preventing moisture from affecting the charging port 2.

[0034] The two lock hooks 43 are arranged in a direction away from the opening so that the inner wall of the lock cavity squeezes the two lock hooks 43 closer to each other to engage the lock head 31, thereby realizing the locking of the elastic latch 4, and in this process the two lock hooks 43 retract toward the inside of the lock cavity so that the end of the charging port cover 3 with the lock head 31 can fit with the vehicle body when locked; the moving block 42 can move toward the direction close to the opening so that the two lock hooks 43 extend from the opening and move away from each other to disengage from the lock head 31, thereby realizing the unlocking of the elastic latch 4, and in this process the two lock hooks 43 extend out of the lock cavity to lift the charging port cover 3, so that a manually openable gap is generated between the charging port cover 3 and the vehicle body. Optionally, the lock hook 43 is provided with a card slot 431, and the card slots 431 of the two lock hooks 43 are arranged opposite to each other. When the two lock hooks 43 approach each other to engage the lock head 31, the opposite ends of the lock head 31 are respectively embedded in the two card slots 431, so that the setting of the card slot 431 can enhance the locking ability of the lock hook 43 on the lock head 31.

[0035] Furthermore, a first bracket 11 is provided on the mounting plate 1. One end of the charging port cover 3 is rotatably mounted on the first bracket 11, thereby providing a certain distance between the charging port cover 3 and the mounting plate 1, facilitating the rotation of the charging port cover 3. The charging port structure also includes a spring clip 5, which is provided on the first bracket 11. The spring clip 5 can elastically abut the other end of the charging port cover 3 away from the lock head 31. Therefore, after the charging port cover 3 rotates excessively, the spring clip 5 can cushion the charging port cover 3 to prevent the charging port cover 3 from being damaged by impact. Specifically, the spring clip 5 includes a U-shaped plug-in portion 51 and an L-shaped abutting portion 52 connected to the U-shaped plug-in portion 51. The U-shaped plug-in portion 51 can be inserted into the first bracket 11, and the L-shaped abutting portion 52 can abut the charging port cover 3. The spring clip 5 has a simple structure and is convenient for mass production. The U-shaped plug-in portion 51 can reduce the difficulty of removing and installing the spring clip 5 on the first bracket 11, making it convenient to repair and replace a failed spring clip 5.

[0036] Furthermore, a second bracket 12 is provided on the mounting plate 1, and the elastic latch 4 is movably provided on the second bracket 12, so that the position of the elastic latch 4 can be fine-tuned, thereby facilitating the alignment operation between the elastic latch 4 and the lock head 31. Specifically, a waist hole is provided on the elastic latch 4, and a connecting bolt is passed through the waist hole and then connected to the second bracket 12. By adjusting the position of the connecting bolt in the waist hole, the position of the elastic latch 4 on the second bracket 12 can be adjusted.

[0037] This embodiment also provides an unmanned vehicle, including the charging port structure as described above. The unmanned vehicle also includes a frame and a battery pack arranged in the frame, and the mounting plate 1 is arranged on the frame. Therefore, the unmanned vehicle uses the charging port structure as described above, so that the user can manually open the elastic cover, thereby avoiding the situation where the charging port cover 3 cannot be opened due to failure of the automatic switch system, and when the elastic latch 4 releases the lock head 31, the charging port cover 3 can be lifted. During this process, the rotation angle of the charging port cover 3 is small, thereby avoiding the charging port cover 3 from rotating excessively and colliding with the vehicle body to cause damage.

[0038] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
