Screw connecting device for automobile interior decoration part

Abstract

The invention discloses a screw connecting device for an automobile interior decoration part. The screw connecting device comprises a screw, a buckle part and an elastic rib, wherein the buckle part comprises a clamping cylinder and inverted parts symmetrically arranged on the two sides of the clamping cylinder, and the clamping cylinder is connected with the inverted parts on the two sides; and the elastic rib is arranged on the inverted parts. Through the design of the specific clamping part, the corner part, the elastic rib and the clamping cylinder part, the clamping force and the anti-disengaging friction force can be achieved, the sliding of an inserting column can be prevented, the target product can be firmly fixed, the fixing mode of the traditional metal screw nut is completely changed, the fixing mode of the automobile interior part is simplified, and the target workpiece can be quickly fixed without an auxiliary tool.

Description

technical field [0001] The invention relates to the technical field of connection mechanisms for automobile interior parts, in particular to a screw connection device for automobile interior parts used to fix two target workpieces. 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. Most of the interior trim products of different manufacturers are fixed by screw connection. [0003] In traditional automotive products, screw fixing is generally used for the connection between relatively heavy-duty parts. However, when connecting large panels and small decorative or functional parts in automotive interior parts, in order to ensure their stability, screw fixing is used. The screw is generally fixed by a combination of a traditional screw and a nut. Since the interior parts through the screws and nuts ...

AI Technical Summary

Problems solved by technology

Since the interior parts through the screws and nuts are exposed to the external environment, they are prone to rust and corrosion. It is very difficult to remove the interior parts, and when disassembling the screws and nuts, auxiliary disassembly tools are needed. It is inconvenient to repair and replace the interior parts in the later period, and it is fixed by screws, which makes assembly difficult and heavy, which does not meet the current lightweight requirements of the automotive industry
