Description

Technical Field

[0001] This utility model relates to the field of PEU cover technology, and in particular to a PEU cover for light-duty special vehicles. Background Technology

[0002] The PEU cover for light-duty special-purpose vehicles is used to cover and protect the power electronic integrated unit (PEU). The PEU integrates multiple key modules such as the motor control unit and DC-DC converter, and is crucial for vehicle power management. PEU covers are generally made of materials such as aluminum alloy, possessing sufficient strength to prevent dust and moisture intrusion, reduce collision damage, and shield against electromagnetic radiation, ensuring stable PEU operation. This is of great significance to the performance and reliability of light-duty special-purpose vehicles.

[0003] Currently, PEU covers for light-duty special vehicles typically have screw holes at the edges for fastening with bolts. However, these screw holes are prone to damage and stripping during use. If even one screw hole is damaged, the entire cover needs to be replaced, significantly reducing its practicality in real-world applications and warranting optimization and improvement. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a light-duty special vehicle PEU cover.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A light-duty special vehicle PEU cover plate includes a cover plate body and a screw hole disposed on its surface near the edge. A connecting post is inserted into the screw hole, and the connecting post and the screw hole are threaded together. One end of the connecting post passes through the screw hole and is fixedly connected to a connecting plate. A through hole is provided between the connecting plate and the connecting post, and an internal thread is fixed in the through hole. An insertion hole is provided on the side of the connecting plate away from the connecting post and near the edge. A limiting rod is slidably inserted on the inner wall of the insertion hole. Both ends of the limiting rod pass through the through hole. The cover plate body has a plurality of limiting grooves distributed in a ring on the side facing the connecting plate, corresponding to the limiting rod.

[0007] Preferably, a sliding groove is provided on the inner sidewall of the insertion hole, and an anti-detachment block is slidably connected to the inner sidewall of the sliding groove. One end of the anti-detachment block passes through the sliding groove and is fixedly connected to the limiting rod.

[0008] Preferably, the anti-detachment block has an arc-shaped groove at the end away from the limiting rod, and a ball bearing is rolled on the inner wall of the arc-shaped groove, with part of the ball bearing penetrating through the arc-shaped groove.

[0009] Preferably, the connecting disc has a toothed pattern on the side away from the connecting post.

[0010] Preferably, a rubber ring is fixedly connected to the side of the connecting plate facing the connecting post.

[0011] Preferably, the end of the limiting rod facing the limiting groove is tapered.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention replaces bolted mounting holes with through holes, connecting posts, connecting discs, and rubber rings, allowing for individual repair and replacement of damaged components. It also provides targeted reinforcement of the bolted holes in the PEU cover plate, increasing the strength of this area and enhancing practicality. Furthermore, the invention's use of limiting rods, anti-loosening blocks, and limiting grooves ensures a stable position lock and prevents loosening of the connecting disc, thus preventing the connecting post from shifting and significantly improving the overall structural reliability. Finally, the connecting posts and connecting discs not only provide localized protection for the bolted holes but also enable individual repair and replacement of damaged components, further enhancing practicality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3A light-duty special vehicle PEU cover plate includes a cover plate body 1 and a screw hole 5 disposed on its surface and near the edge. A connecting post 6 is inserted into the screw hole 5 to mate with the screw hole 5 of the bag body through hole 3. The connecting post 6 and the screw hole 5 are connected by threads. One end of the connecting post 6 passes through the screw hole 5 and is fixedly connected to a connecting plate 2 to protect the surface of the cover plate body 1. A through hole 3 is provided between the connecting plate 2 and the connecting post 6 to mate with the internal thread to connect bolts. An internal thread is fixed in the through hole 3. A toothed pattern 4 is fixed on the side of the connecting plate 2 away from the connecting post 6 to improve the tightness between the bolt and the connecting plate 2 after tightening. A rubber ring 7 is fixedly connected on the side of the connecting plate 2 facing the connecting post 6 to prevent wear between the connecting plate 2 and the cover plate body 1.

[0020] In this embodiment, the connecting plate 2 has an insertion hole on the side away from the connecting column 6 and near the edge. A limiting rod 8 is slidably inserted on the inner wall of the insertion hole to prevent the connecting plate 2 from rotating or loosening. The two ends of the limiting rod 8 pass through the through hole. The cover plate body 1 has a plurality of limiting grooves 9 corresponding to the limiting rod 8 arranged in a ring on the side facing the connecting plate 2 for inserting the limiting rod 8. The end of the limiting rod 8 facing the limiting groove 9 is tapered to reduce the difficulty of inserting the limiting rod 8 into the limiting groove 9.

[0021] In this embodiment, a sliding groove is provided on the inner side wall of the socket, and an anti-detachment block 10 is slidably connected to the inner side wall of the sliding groove. This anti-detachment block 10 is used to cooperate with the sliding groove to limit the movement of the limiting rod 8 and prevent it from completely detaching from the socket. One end of the anti-detachment block 10 passes through the sliding groove and is fixedly connected to the limiting rod 8. An arc-shaped groove is provided at the end of the anti-detachment block 10 away from the limiting rod 8. A ball bearing 11 is slidably connected to the inner side wall of the arc-shaped groove to reduce the resistance when the anti-detachment block 10 moves. Part of the ball bearing 11 passes through the arc-shaped groove.

[0022] In this embodiment, the connecting plate 2 first protects the surface of the cover plate body 1, preventing damage to the surface of the cover plate body 1 caused by tightening the bolts during installation. The connecting post 6 protects the inner wall of the screw hole 5 and, together with the through hole 3, replaces the screw hole 5 to insert the connecting bolt. After the bolt is inserted into the through hole 3 and tightened, it will squeeze the limiting rod 8 and push the limiting rod 8 into the limiting groove 9, thereby locking the rotation capability of the connecting plate 2, preventing the connecting plate 2 from rotating or loosening, and improving reliability. During the disassembly and assembly process, the bolt may be damaged by repeated tightening. If the thread inside the through hole 3 is damaged, the connecting post 6 can be unscrewed from the screw hole 5 and replaced.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
