Description

Technical Field

[0001] This utility model relates to the field of new energy protective plate technology, specifically to a riveting structure for connecting bottom protective plates. Background Technology

[0002] New energy vehicle underbody protection plates typically refer to the protective plates on the bottom of new energy vehicles. Their main function is to protect critical components on the bottom of the vehicle, such as the battery pack, drive motor, and other electronic components, from external environmental impacts, such as impacts from stones, mud, or other objects.

[0003] Existing new energy vehicle underbody protection plates are mostly fixed by riveting during installation. This fixing method is simple and convenient, and easy for personnel to disassemble. However, the existing new energy vehicle underbody protection plates are mostly fixed by directly contacting the rivets with the plate. Although this method can achieve a fixing effect, the contact area between the rivets and the plate is often relatively small. When subjected to vibration, it is easy to loosen, thus affecting the fixing effect of the new energy vehicle underbody protection plate. Therefore, it has certain shortcomings.

[0004] In conclusion, it is necessary to invent a riveting structure for connecting bottom protective plates. Utility Model Content

[0005] Therefore, this utility model provides a riveting structure for connecting the bottom guard plate, which solves the problem that although this method can achieve a fixing effect, the contact area between it and the new energy bottom guard plate is often relatively small, and it is easy to loosen when subjected to vibration, thus affecting the fixing effect of the new energy bottom guard plate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a riveting structure for connecting a bottom guard plate, comprising a rivet head, a rivet rod integrally fixed to the bottom of the outer wall of the rivet head, a riveting clamp for riveting provided on the outer wall of the rivet rod, a bottom guard plate to be fixed provided between the rivet head and the riveting clamp, and a fixing component for auxiliary fixing of the bottom guard plate provided on the bottom of the outer wall of the rivet head and on one side of the rivet rod.

[0007] Preferably, the fixing component is a second bushing, which is disposed on the outside of the rivet rod, and a second countersunk groove for receiving the rivet head is provided at the top of the outer wall of the second bushing.

[0008] Preferably, a protrusion is fixed at the bottom of the outer wall of the second bushing at a position corresponding to the hole wall of the bottom protective plate, and an adhesive layer is sprayed on the bottom of the outer wall of the second bushing and the outer wall of the protrusion at the connection with the bottom protective plate.

[0009] Preferably, a deformation block is fixed to the top of the outer wall of the riveting clamp, and a rivet sleeve is connected to the outer wall of the rivet rod below the riveting clamp.

[0010] Preferably, the fixing component is a first bushing, which is disposed on the outside of the rivet rod, and the top of the outer wall of the first bushing is provided with a first countersunk groove for receiving the rivet head.

[0011] Preferably, a side groove is provided on the outer wall side of the first bushing at a position corresponding to the hole wall of the bottom protective plate, and the inner wall of the side groove abuts against the hole wall of the bottom protective plate.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, a bushing is provided between the rivet head and the bottom guard plate for auxiliary fixing. The bushing increases the contact range between the rivet head and the bottom guard plate, thereby enhancing the strength of the riveted part, reducing loosening of the connection due to vibration or impact, and improving the shear resistance of the riveting, making it more stable under greater loads and more convenient for personnel to use.

The riveting clamp 200 can deform under pressure, thereby cooperating with the rivet head 100 to fix the bottom guard plate 500. The bottom guard plate 500 to be fixed is provided between the rivet head 100 and the riveting clamp 200. The bottom of the outer wall of the rivet head 100 is located at the bottom of the rivet rod. A fixing component for auxiliary fixing of the bottom guard plate 500 is provided on one side of 110. The fixing component is a second bushing 400, which is located on the outside of the rivet rod 110. The top of the outer wall of the second bushing 400 has a second countersunk groove 410 for receiving the rivet head 100. The second countersunk groove 410 is provided to receive the second bushing 400 and to allow the clamping force of the rivet head 100 to be transmitted to the outer wall of the bottom guard plate 500 through the second bushing 400. The bottom of the outer wall of the second bushing 400... A protrusion is fixed at a position corresponding to the hole wall of the bottom protective plate 500. The protrusion is designed to allow the bottom end of the second bushing 400 to be inserted into the riveting hole in the bottom protective plate 500. Both the bottom end of the outer wall of the second bushing 400 and the outer wall of the protrusion are coated with an adhesive layer 420 at their connection points with the bottom protective plate 500. The adhesive layer 420 is designed to further improve the fixing effect between the second bushing 400 and the outer wall of the bottom protective plate 500. The adhesive layer 420 can be made of polyurethane adhesive. The riveting clamp 200...
