[0001] This utility model belongs to the field of lithium battery fast charging interface technology, specifically relating to a lithium battery fast charging interface suitable for logistics vehicles. Background Technology

[0002] With the rapid development of society and in response to the principle of green environmental protection, the use of electric vehicles in the logistics field is becoming increasingly common. In electric logistics vehicles, the lithium battery fast charging interface is an important component. However, in the existing logistics vehicle lithium battery fast charging interfaces, the charging gun is directly inserted into the fast charging interface. When the charging gun is pulled by external force, it is easy to fall out of the fast charging interface, affecting the charging quality. Therefore, we propose a lithium battery fast charging interface suitable for logistics vehicles. Summary of the Invention

[0003] The purpose of this utility model is to provide a fast charging interface for lithium batteries suitable for logistics vehicles. By designing an installation panel, fast charging interface, fixing screws, charging gun, and limiting mechanism, the connection between the charging gun and the fast charging interface is more secure during use. The charging gun will not easily fall off the inside of the fast charging interface due to external pulling, making the connection between the charging gun and the fast charging interface more stable and ensuring better charging quality. The overall structure is simple and highly practical.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery fast charging interface suitable for logistics vehicles, including a mounting panel, a fast charging interface provided on the front side of the mounting panel, fixing screws provided at the four corners of the front side of the mounting panel, a charging gun adapted to the fast charging interface provided on the front side of the fast charging interface, a limiting mechanism provided between the mounting panel and the charging gun, the limiting mechanism including an L-shaped plate at the top of the fast charging interface, a rotating shaft fixedly connected to one end of the L-shaped plate near the mounting panel, side plates rotatably connected to both ends of the rotating shaft, the side plates being fixedly connected to the mounting panel, an arc-shaped retaining strip adapted to the L-shaped plate provided on the top surface of the charging gun, and a spring provided between the fast charging interface and the L-shaped plate.

[0005] Preferably, it also includes a protective mechanism, which includes a protective cap located in front of the fixing screw. The mounting panel surface is also fixed with a fixing ring adapted to the protective cap. The top and bottom of the front side of the fixing ring are both provided with notches. The side of the protective cap near the fixing screw is provided with a locking block adapted to the notches.

[0006] Preferably, the curvature of the bottom surface of the L-shaped plate is the same as the curvature of the bottom surface of the arc-shaped card strip.

[0007] Preferably, the L-shaped plate, the pivot, the side plate, and the arc-shaped clip are all made of plastic.

[0008] Preferably, the distance between the front surface of the fixing ring and the front surface of the mounting panel is 0.5 cm.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. By designing the mounting panel, fast charging interface, fixing screws, charging gun, and limiting mechanism, the connection between the charging gun and the fast charging interface is made more secure during use. The charging gun will not easily fall off the inside of the fast charging interface due to external pulling, making the connection between the charging gun and the fast charging interface more stable and ensuring better charging quality. The overall structure is simple and highly practical.

[0011] 2. By designing a protective mechanism, after the fixing screw is installed, the operator can push the protective cap from the front of the fixing ring, causing the protective cap to drive the locking block to insert from the inside of the notch. Then, the operator can rotate the protective cap 90 degrees to fix it in the designated position, effectively wrapping the fixing screw and providing a certain degree of protection. This prevents the surface of the fixing screw from oxidizing due to wear, thus improving the service life of the fixing screw. Attached Figure Description

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2This utility model provides a technical solution: a lithium battery fast charging interface suitable for logistics vehicles, including a mounting panel 1, a fast charging interface 2 disposed on the front side of the mounting panel 1, fixing screws 3 disposed at the four corners of the front side of the mounting panel 1, a charging gun 4 adapted to the fast charging interface 2 disposed on the front side of the fast charging interface 2, and a limiting mechanism disposed between the mounting panel 1 and the charging gun 4, the limiting mechanism including an L-shaped plate 5 at the top of the fast charging interface 2, a rotating shaft 6 fixedly connected to one end of the L-shaped plate 5 near the mounting panel 1, and side plates 7 rotatably connected to both ends of the rotating shaft 6. The side plate 7 is fixedly connected to the mounting panel 1. The top surface of the charging gun 4 is provided with an arc-shaped retaining strip 8 that matches the L-shaped plate 5. A spring 9 is also provided between the fast charging port 2 and the L-shaped plate 5. The curvature of the bottom surface of the L-shaped plate 5 is the same as that of the bottom surface of the arc-shaped retaining strip 8. When the L-shaped plate 5 and the arc-shaped retaining strip 8 are engaged, the connection between the fast charging port 2 and the charging gun 4 becomes more secure. The L-shaped plate 5, the pivot 6, the side plate 7, and the arc-shaped retaining strip 8 are all made of plastic, effectively reducing manufacturing costs. When it is necessary to connect the fast charging port... When connecting the charging gun 4 to the fast charging port 2, the operator first moves the L-shaped plate 5 upwards, causing it to rotate upwards around the pivot 6. At this time, the spring 9 is stretched open. Once the L-shaped plate 5 reaches the appropriate position, the operator inserts the charging gun 4 into the inside of the fast charging port 2. Then, the operator releases the L-shaped plate 5, causing the spring 9 to contract and return the L-shaped plate 5 to its original position, so that the bottom end of the L-shaped plate 5 is on one side of the arc-shaped retaining strip 8, thus limiting the movement of the charging gun 4. Currently, in the use of existing fast charging ports for lithium batteries in logistics vehicles, the charging gun is directly inserted into the fast charging port. Inside interface 2, when the charging gun is pulled by external force, it is easy to fall off from the inside of the fast charging interface 2, affecting the charging quality. By designing the mounting panel 1, fast charging interface 2, fixing screw 3, charging gun 4, and limiting mechanism, the connection between the charging gun 4 and the fast charging interface 2 is made more secure during use. The charging gun 4 will not easily fall off from the inside of the fast charging interface 2 due to external force, making the connection between the charging gun 4 and the fast charging interface 2 more stable and ensuring better charging quality. The overall structure is simple and highly practical.

[0018] In this embodiment, preferably, please refer to... Figure 1 , Figure 3As shown, it also includes a protective mechanism, which includes a protective cap 10 located in front of the fixing screw 3. A fixing ring 11 adapted to the protective cap 10 is also fixed on the surface of the mounting panel 1. The top and bottom of the front side of the fixing ring 11 are both provided with notches 12. The side of the protective cap 10 near the fixing screw 3 is provided with a locking block 13 adapted to the notch 12. The distance between the front surface of the fixing ring 11 and the front surface of the mounting panel 1 is 0.5 cm. When personnel install the fixing screw 3, the fixing ring 11 will not obstruct it. By designing the protective mechanism, after the fixing screw 3 is installed, the personnel can push the protective cap 10 from the front side of the fixing ring 11, so that the protective cap 10 drives the locking block 13 to be inserted from the inside of the notch 12. Then, the personnel can rotate the protective cap 10 90 degrees to fix the protective cap 10 in the designated position, which effectively wraps the fixing screw 3 and provides a certain degree of protection for the fixing screw 3, so that the surface of the fixing screw 3 will not be oxidized due to wear, thus improving the service life of the fixing screw 3.
