Description

technical field [0001] The invention relates to an automobile accessory, in particular to an automobile sunroof sealing strip. Background technique [0002] Automobile sealing strip is one of the important parts of automobiles. It is widely used in doors, windows, body, sunroof, engine box and backup (luggage) box and other parts. It has the functions of sound insulation, dustproof, water seepage prevention and shock absorption. Maintain and maintain the small environment in the car, thus playing an important role in protecting the occupants, electromechanical devices and accessories in the car. [0003] Patent document CN206416826U, announcement date 2017.08.18, discloses a kind of sealing strip for automobile sunroof, comprising a sealing main body, a cavity is formed in the sealing main body, the cavity is filled with a gel filler, the gel The filler is liquid glue, and the gel filler fills the cavity, and the cavity extends along the length direction of the sealing main...

AI Technical Summary

Problems solved by technology

[0005] However, on the one hand, the cross-section of the automotive sunroof sealing strip itself is small, and it is a very difficult process to fill the cavity with rubber filler, and if it is scratched or aged and cracked, the internal rubber filler will seep out, and it will be damaged. Seriously affect the environment inside the car; on the other hand, the car sunroof sealing strip is fixed by snap-fitting with the slot of the main body of the sunroof. The gap between the buckle and the slot has the possibility of water seepage, which affects the sealing performance and is easy to accumulate dust. Form a hygienic dead corner and affect the environment inside the car; thirdly, because the car sunroof sealing strip is a rubber product, it has a certain shrinkage and is easily stretched and deformed by external forces. This reason often leads to defective products, or the main body of the car sunroof Can not be well matched, or local deformation and thinning are caused by stretching and shrinkage after long-term use, and the automotive sunroof sealing strips in the above-mentioned documents also have this defect; fourthly, rubber products are sometimes in the process of friction and extrusion. High-frequency noise will be generated, affecting the sense of use, and the automotive sunroof sealing strips in the above-mentioned documents have not solved this technical problem
