Description

Novel automobile skylight sealing strip

Technical Field

The utility model relates to an auto-parts, specifically speaking is a novel sunroof sealing strip.

Background

The automobile sealing strip is one of important parts of an automobile, is widely used for parts such as automobile doors, automobile windows, automobile bodies, skylights, engine cases, trunk (trunk) boxes and the like, has the functions of sound insulation, dust prevention, seepage prevention and shock absorption, and can maintain and maintain the small environment in the automobile, thereby playing an important role in protecting passengers, electromechanical devices and accessories in the automobile.

Patent document CN206416826U, published japanese patent No. 2017.08.18, discloses a weather strip for an automobile sunroof, which includes a sealing main body portion, a cavity is formed in the sealing main body portion, a glue filler is filled in the cavity, the glue filler is liquid glue, the cavity is filled with the glue filler, the cavity extends along the length direction of the sealing main body portion, and the sealing main body portion is annular; the sealing strip for the automobile skylight is convenient to connect with the skylight main body, the sealing performance between the skylight main body and the automobile body can be ensured, the connecting part can be a buckle, clamping grooves can be formed in the periphery of the skylight main body, and the sealing strip for the skylight can be clamped with the clamping grooves of the skylight main body through the buckle so as to be connected with the skylight main body; the sealing strip for the automobile skylight further comprises a sealing bulge, the sealing bulge is connected with the sealing main body part and extends back to the connecting part, and the sealing bulge is used for being in contact with the automobile body; the sealing strip for the automobile skylight further comprises a water guide part, and the water guide part is connected with the sealing main body part and used for guiding flowing water.

Above sealing strip for sunroof main advantage lies in that the cavity of sealed main part is filled with gluey filler, gluey filler can play the supporting role to sealed main part, consequently can strengthen the elasticity and the intensity of sealed main part, because gluey filler has mobility, consequently can make the deformation of sealed main part more even, when sealing strip for sunroof presss from both sides and establishes between skylight main part and automobile body and produce deformation, can strengthen the laminating degree of sealing strip for sunroof and skylight main part and automobile body, thereby sealing performance has been improved.

On one hand, however, the section of the automobile skylight sealing strip is small, the filling of the rubber filler in the cavity is a difficult process, and if the automobile skylight sealing strip is scratched or aged and cracked, the rubber filler in the automobile skylight sealing strip seeps out, so that the environment in the automobile is seriously influenced; on the other hand, the automobile skylight sealing strip is fixedly clamped with the clamping groove of the skylight main body through the buckle, and the gap between the buckle and the clamping groove has the possibility of water seepage, so that the sealing property is influenced, dust is easily accumulated, a sanitary dead angle is formed, and the environment in an automobile is influenced; in a third aspect, since the sunroof sealing strip is a rubber product, it has a certain shrinkage and is easily stretched and deformed by an external force, which often results in a poor product, or a poor matching with the sunroof body, or a local deformation and thinning caused by stretching and shrinking after a long time use, and the sunroof sealing strip in the above documents also has the defect; in the fourth aspect, high-frequency noise may be generated in the rubber product during the rubbing and pressing process, which may affect the use sense, and the sunroof sealing tape in the above-mentioned document does not solve the problem.

In conclusion, a need exists for a sealing strip for an automobile sunroof, which has good sealing performance, is simple and convenient in process, resists deformation, and reduces abnormal sound.
