Roof molding and its installation structure

Abstract

The invention provides a car roof decorative strip and an installing structure thereof. The car roof decorative strip comprises a car roof decorative strip body (1) and a fastener (9), wherein the car roof decorative strip body comprises a decorative strip body and decorative strip lip pieces (3) located on two sides and used for adhering to the car roof face during installation. The car roof decorative strip is characterized in that two convex ribs (4) are arranged on the back side of the car roof decorative strip body along the longitudinal direction and provided with a plurality of gaps (5) at the same longitudinal positions at set intervals (a) respectively, and the side faces of the convex ribs located on two sides of each gap are provided with side holes (6) at set interval (b). The fastener comprises a base plate (14), a transverse convex rib (10) is arranged in the middle of the base plate, two sides of the transverse convex rib are provided with four bent buttons (11) for being embedded into the side holes of the car roof decorative strip body, and at least one elastic support foot (12) is arranged at two ends of the base plate respectively and obliquely extends out of the two ends of the base plate upward and outward. A double-sided sticky tape (13) is bonded on the back side of the base plate.

Description

technical field [0001] The invention relates to a roof molding and its installation structure. Background technique [0002] The roof molding is a decorative part used to decorate the roof and the side panel. At present, there are two main types, one is all made of organic elastomer materials, and the other is a scheme that uses metal skeletons to outsource organic elastomer materials, which are generally formed by continuous extrusion (also called extrusion) technology. The former is called pure extrusion. process, the corresponding roof trim is also called pure press trim; the latter uses metal strips to form a skeleton by rolling, and then extrudes online to wrap the organic elastomer material outside the skeleton, which is called re-pressing process , the corresponding roof trim is also called compound trim. There are two main ways to install the roof trim, one is to stick it with adhesive tape, usually 3M tape; the other is to use plastic buckle (called CLIP in Englis...

AI Technical Summary

Problems solved by technology

The disadvantage of pure embossed strips is that the product is not rigid enough. Due to the large gap between the roof and the side panel, the surface is prone to appearance defects such as plastic shrinkage marks. In addition, the long section of tape is easy to curl and peel off during the use of the vehicle.

Generally, the buckle connection scheme is adopted for double-walled decorative strips; due to the existence of a metal skeleton, double-walled decorative strips are relatively heavy in weight, and special bending processes are required during processing. The manufacturing process is relatively complicated and cannot be as good as plastics. Toughness naturally adheres to the roof surface
