[0030] Example 1

[0031] like Figure 3-8 As shown, the structure for preventing the loosening of the riveting platform of plastic parts in this embodiment includes a riveting column 100 and a riveting platform 200. The riveting platform 200 includes a platform body 300, and the platform body 300 is a hollow structure, and a reinforcing rib structure 400 is provided in the middle of its upper wall. The reinforcing rib structure 400 is integrally injection molded with the platform body 300. The reinforcing rib structure 400 includes an inner ring 410 and an outer ring 420, and the inner ring 410 and the outer ring 420 are connected by a plurality of spoke reinforcing ribs 430, and the adjacent spoke reinforcing ribs 430 are hollow structures. The area enclosed by the cross section of the platform body 300 gradually decreases from bottom to top. The cross section of the platform body 300 in the figure is rectangular or square, and of course the cross section of the platform body 300 can also be circular. The lower surface of the platform body 300 is an open structure. When the cross section of the platform body 300 is rectangular or square, the side wall of the platform body 300 is a trapezoidal structure. The riveted column 100 includes a riveted tube 110 and a plurality of reinforcing plates 120 disposed on the side wall of the riveted tube 110. The plurality of reinforcing plates 120 are symmetrically disposed around the side wall of the riveted tube 110. The reinforcing plates 120 are trapezoidal structures and are disposed along the vertical direction of the side wall of the riveted tube 110. The riveted column 100 extends the reinforcing rib structure 400 from the inside of the platform body 300. The reinforcing plates 120 of the riveted column 100 support the upper wall of the platform body 300, and the upper end of the riveted tube 110 forms a mushroom head under the pressure of the riveting tool, and the mushroom head forms a concave-convex matching structure with the spoke reinforcing rib 430.

[0032] The mushroom heads formed in this embodiment form a concave-convex structure, which can effectively prevent the plastic parts from loosening and causing abnormal noise after assembly. In addition, the ribs arranged on the riveting platform are the first to be contacted by the riveting tooling during the riveting process, which can effectively protect the structural strength of the riveting platform. The structure of this embodiment is implemented in the map pocket body of the door guard plate of a certain vehicle model, wherein a riveting platform is arranged on the door guard plate map pocket body, and a riveting column is arranged on the door guard plate body. The two cooperate in a total of 10 structures for connecting the door guard plate map pocket and the door guard plate body. Through the riveting process, they are connected to form the same component. By arranging the reinforcing ribs on the riveting platform on the door guard plate map pocket, and cooperating with the rivet columns arranged on the door guard plate body to form a concave-convex structure, the loosening of the door guard plate map pocket and the door guard plate body can be effectively prevented, and the occurrence of abnormal noise problems can be avoided.
