Automotive trim clip

Abstract

The invention discloses a buckle for an automobile interior decoration, which comprises a buckle body. The outer sides of the buckle body are respectively provided with anti-falling undercut protrusions. The lower part of the anti-falling underturn protrusion is an outer clamping part. A pair of ribs are provided on the inner side of the buckle body, the ribs are provided with anti-falling barbs, and the ribs or the inner side of the buckle body are provided with clamping bosses, and the anti-falling barbs are fixed on the target connecting piece. The mounting holes or mounting protrusions fix the target connecting piece to prevent falling off. Compared with the traditional metal shrapnel, the present invention completely solves the technical problems of shrapnel shaking, abnormal noise, loose connection and difficult maintenance caused by the high energy consumption and poor welding risk of traditional metal shrapnel hot-melt welding. Undercut protrusions, anti-falling barbs and clamping bosses can firmly connect the target connecting parts, which are easy to install and easy to replace.

Description

technical field [0001] The invention belongs to a connecting piece of an automobile interior decoration, and in particular relates to an injection molding buckle of an automobile interior decoration. Background technique [0002] At present, automobile production has become a mature modular production mode. Automobile OEMs distribute various parts to sub-suppliers for production, and then centralize procurement and assembly. Then, most of the interior parts products of different manufacturers are connected and assembled through screws and buckles. [0003] In traditional automotive products, the hook is in the form of a metal shrapnel, which is welded to the plastic part by hot-melt welding. like figure 1 As shown, the traditional hook is made of spring steel, stamped and then coated. Made into a sheet product with an elastic structure. Generally, two holes are left for combination with plastic products, and then fixed together by hot-melt welding. The disadvantage of t...

AI Technical Summary

Problems solved by technology

The disadvantage of this traditional process is that during hot-melt welding, the welding time is relatively long. Generally, it takes 12 seconds to melt the plastic, and it can be fixed after solidification again. If the hot-melt machine is unstable, it will cause the risk of poor welding. Moreover, the cost of hot-melt welding machines and daily maintenance is not a small expense, and the welding energy consumption is high, and the production cost will increase accordingly, and the welded connector products are not easy to repair after falling off
