Automobile skylight sealing strip

Abstract

The invention relates to an automobile sunroof sealing strip. It includes a first horizontal section (1), an arc section (2), a vertical section (3) and a second horizontal section (5). A ring section (4) is set outside the right end of the second horizontal section (5). Teeth (6) are provided on the inside of the two horizontal sections (5), the upper end of the arc section (2) is connected to the upper end of the vertical section (3), and the lower end of the arc section (2) is connected to the lower end of the vertical section (3) , the arc section (2) and the vertical section (3) form a hollow structure (8), and a comb-shaped insert (9) made of resin is embedded in the sealing strip, and the insert (9) includes a body (9.1 ) and teeth (9.2), the surface of the sealing strip is coated with an insulating coating. The invention provides an automobile sunroof sealing strip, which can effectively insulate, and has tight fit, high compression rate, easy installation and good sealing performance. At the same time, the sealing member has a large grasping force on the mating parts and has good flexibility in the bending operation process.

Description

technical field [0001] The invention relates to a sealing strip, which is suitable for the sunroof of an automobile. It belongs to the technical field of auto parts. Background technique [0002] At present, there are sunroofs in the configuration of domestic cars. The conventional idea of ​​the sunroof sealing strip is: dense rubber + sponge rubber + flocking (or coating) composite, and the dense rubber paint is fixed, that is, the rubber strip is installed on the sunroof sheet metal; the sponge The elastic sealing function of the rubber paint is the sealing between the glass and the roof sheet metal; the flocking (or coating) can reduce the frictional resistance between the sealing strip and the glass. [0003] Since the sunroof is a rather special part of the car body, it is located on the roof and must withstand the direct test of rainwater, so the requirements for sealing are extremely high. Therefore, the disadvantages of conventional sealing strips are: [0004] Th...

AI Technical Summary

Problems solved by technology

[0004] The sealing strip is extruded once, and the car sunroof is generally rectangular. When the sealing strip is installed, the sponge tube at the corner will often collapse, which will greatly reduce the contact between the sealing strip and the glass, resulting in water leakage on the sunroof

[0005] The existing sealing strip is made of pure rubber material, so the gripping force on the fittings is small, and the flexibility is poor during the bending operation, which cannot meet the needs of customers

[0006] The surface insulation effect of the existing automotive sunroof sealing strip is poor, which cannot meet the needs of customers
