Brightness decoration strip and special fastener of guide slot sealing strip

Abstract

The invention relates to the mechanical technique field, in particular to a brightness decoration strip and a special fastener of a guide slot sealing strip, comprising an insert body and an elastic clip, wherein the insert body comprises a reinforced rib, a step rib and a craft positioning rib; the elastic clip comprises a positioning pin, a fixing pin, a sub-clip and a main clip. Compared with the prior art, in the invention, a special fastener is adopted to be embedded into joint corners at two ends of the guide slot sealing strip and matched with a plastic buckle on the brightness decoration strip, thereby realizing fixation of the vehicle body at the width direction and avoiding the problem of gap and transformation happening in assembling of the brightness decoration strip and the guide slot sealing strip; the fastener in the joint corner of the guide slot sealing strip can improve the strength of elastomer material of the guide slot sealing strip itself, so that compact matching of the guide slot sealing strip with outer cover plates of car-doors is realized and the problem of guide slot sealing strip transformation caused by extrusion is avoided.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a special clip for bright decorative strips and guide groove sealing strips. Background technique [0002] With the rapid development of the automobile industry, the requirements for the appearance of models are also getting higher and higher. The matching accuracy of the components on the outer frame of the door will directly affect the quality of the vehicle. As an important appearance part, the channel sealing strip is very important to cooperate with the bright trim and the outer door cover panel. At present, the bright decorative parts used in China can be divided into: plastic chrome-plated bright decorative parts, stainless steel bright decorative parts, aluminum alloy bright decorative parts, and film bright decorative parts. Considering the reasons of cost and workmanship, stainless steel bright decorative parts and aluminum alloy bright decorative parts are more com...

AI Technical Summary

Problems solved by technology

The defects in these three forms are as follows: 1) The process of the adhesive structure is complex, the stability is not strong, the cost is high, and there is dependence on special equipment for gluing; 2) The process of the integral extrusion structure is complex and the scrap rate is high 2. The brightness of the exterior surface of bright decorative parts is affected; 3) Although the clamping structure is highly adopted and the process is simple, since the guide groove sealing strip is made of EPDM or TPV material, it has certain elastic properties, so no matter which type is used The clamping method, after the guide groove sealing strip and the bright decorative parts are clamped and assembled, and then installed on the vehicle body with a certain curvature in the width direction of the vehicle body, it is inevitable that there will be problems of elastic rebound and poor fastening matching, especially the two At the end, it is more prone to seam separation, which affects the appearance, is easy to fall off, and fails in performance

[0004] During the assembly process of the guide groove sealing strip and the door outer cover plate, the door outer cover plate cannot be positioned, and the interference assembly part is prone to excessive interference, which will cause the elastic body of the guide groove seal strip to be deformed or not assembled properly, and the boundary of the door outer cover plate will be damaged. Exposed, there is a gap between the door outer cover plate and the guide groove sealing strip
