Automobile skylight sealing strip with partition structure

Abstract

The invention belongs to the technical field of automobile skylights and relates to an automobile skylight sealing strip with a partition structure. The sealing strip comprises a sponge rubber large foam area, a dense rubber connecting area and a sponge rubber small foam area; a foaming agent is added into materials of the sponge rubber large foam area and the sponge rubber small foam area, so that texture is soft and elastic; the foaming agent is not added into materials of the dense rubber connecting area, so that texture is hard; the sponge rubber large foam area is shaped like a transversely arranged hook with an opening downwards to the right; a cross section of the dense rubber connecting area is in a vertical bending hook shape, the lower part of the dense rubber connecting area isprovided with a clamping groove, the outer side of the upper part of the dense rubber connecting area is provided with a viscose body, a fiber thread penetrating through the dense rubber connecting area is arranged in the dense rubber connecting area, and the dense rubber connecting area is connected to the sponge rubber large foam area to form a hollow structure; and a cross section of the spongerubber small foam area is of a hollow annular structure and the sponge rubber small foam area is connected to the dense rubber connecting area. The automobile skylight sealing strip with the partition structure has the advantages that the partition structure design is provided, the sealing performance is good, the noise reduction performance is excellent, the loosening phenomenon is effectively prevented, and the installation, the disassembly and the replacement are convenient.

Description

technical field [0001] The invention relates to the technical field of automobile sunroofs, in particular to an automobile sunroof sealing strip with partition structure. Background technique [0002] The sealing strips of the existing car sunroof maintain the conventional design, and it does not take into account that when the sunroof is opened and closed, due to the force and deformation of the contact surface, the sealing strip will be transmitted to other parts of the sealing strip, which will cause it to be linked. In some cases, it is easy to generate noise that could have been avoided, and even cause loosening of related structural fits. [0003] Chinese patent document: CN204749821U discloses a kind of outer sliding sealing strip structure of panoramic sunroof. It includes glass, the sunroof shell and two guide rails arranged on both sides of the shell. The structure also includes a seal and a pipe fitting fixedly connected to the sunroof shell. The two guide rails ...
