Rapid assembling and limiting structure of decorative plate

Abstract

The invention discloses a rapid assembling and limiting structure of a decorative plate. The rapid assembling and limiting structure comprises an outer plate and a skeleton. The outer plate and the skeleton correspond to each other in shape. The skeleton is provided with two sets of oppositely-arranged sunken table hooks and a set of T-shaped steps. The outer plate is provided with two sets of protruding hooks matched with the sunken table hooks, and T-shaped grooves matched with the T-shaped steps. Up-down limiting of the outer plate and the skeleton in the mounting direction is ensured through matching of the sunken table hooks and the protruding hooks. Left-right limiting of the outer plate and the skeleton in the mounting direction is ensured through matching of the T-shaped steps andthe T-shaped grooves. The rapid assembling and limiting structure is simple in structure, assembly is achieved by relying on the self hook structure, it is ensured that connecting technologies such asscrews, glue or welding do not need to be used in the assembling process, and disassembly of the outer plate and the skeleton is facilitated.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a quick assembly structure of a decorative panel. Background technique [0002] For the automobile industry, lightweight will be the theme throughout the 21st century. Lightweight materials such as plastic parts are increasingly used in automobiles, such as the application of aluminum alloy engine covers, plastic fenders and plastic back doors. important direction. Especially in the plastic back door assembly, it involves overlapping and assembling of various plastic parts (hereinafter collectively referred to as decorative panels) such as upper spoiler, side spoiler, back door outer panel. In order to realize the styling requirements, these decorative panels are often formed by assembling parts such as inner panels and outer panels. Patent ZL201520701207.1 proposes a side spoiler. It can be seen from the patent document that the side spoiler of this patent is as...

Problems solved by technology

This kind of connection cannot be disassembled, and the decorative panel is used as a car decoration, and the outer panel may often have a variety of colors to choose from, and it is exposed on the outside of the car. Due to the surface damage of the plastic part, such as scratches, etc., it cannot be repaired, and only parts can be replaced. , and the entire assembly must be replaced when the spoiler is replaced, which increases the maintenance cost

At the same time, the traditional decorative panel assembly is used as an exterior part, and its packaging and transportation links need to pay attention to the protection of the appearance quality, while the skeleton structure is more complicated, there may be metal buckles, bolts and other structures, the outer panel and skeleton assembly supply When the frame is easy to scratch the outer plate, the defect rate increases and the manufacturing cost of the part is increased.
