Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to a sealing structure for an automobile skylight. Background Art
[0002] With the rapid development of society and the popularization of automobiles, consumers' requirements for the appearance and shape of automobiles are constantly increasing, so the configuration of automobiles also needs to be improved accordingly. Skylights are adopted by many car companies as a configuration that can increase the lighting area and improve the appearance quality.
[0003] Most skylights have an integral PU edging injection-molded around the glass to provide sealing and aesthetic decoration. To prevent rain from entering the car, traditional sealing strips are usually bonded to the PU edging with 3M adhesive. This type of sealing strip is prone to falling off after long-term use, and the bonding process is complicated, resulting in low production efficiency and high production costs. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned shortcomings and provides a sealing structure for an automobile sunroof, which has a simple production process, quick assembly, improved production efficiency and cost savings.
[0005] The purpose of the utility model is achieved in this way:
[0006] A sealing structure for a car sunroof, comprising sunroof glass, PU edging and a sunroof sealing strip, wherein the sunroof glass is circumferentially provided with a PU edging, and the front and rear sides of the PU edging are respectively connected to the sunroof sealing strip, the sunroof sealing strip is in a strip shape, and comprises an integrally formed T-shaped mounting portion and a sealing lip, the PU edging is provided with a mounting slot corresponding to the T-shaped mounting portion, the sunroof sealing strip is clamped in the mounting slot through the T-shaped mounting portion, the sealing lip is arranged outwardly, and the sunroof sealing strip is provided with limiting notches at both ends along the length direction, the limiting notches are arranged on the T-shaped mounting portion, and the mounting slot is provided with a protrusion corresponding to the limiting notch.
[0007] Preferably, the sealing lip corresponding to the rear skylight sealing strip abuts against the rear vehicle body, and the sealing lip corresponding to the front skylight sealing strip abuts against the front vehicle body.
[0008] Preferably, the front vehicle body includes a canopy front glass and a canopy front glass PU edging arranged around the canopy front glass, and the canopy front glass serves as an extension of the canopy glass.
[0009] Preferably, the T-shaped mounting portion is made of TPV hard rubber or EPDM hard rubber material, and the sealing lip is made of TPV soft rubber or EPDM soft rubber material.
[0010] Preferably, the T-shaped mounting portion is further provided with a core material along the length direction, and the core material is copper wire or glass fiber material.
[0011] Preferably, the skylight sealing strip is flush with the left and right ends of the front vehicle body and the rear vehicle body.
[0012] The beneficial effects of the utility model are:
[0013] The utility model has a simple production process and quick assembly. By clamping the canopy sealing strip on the front and rear sides of the PU edge, and setting mutually matching limiting mechanisms at the front and rear ends of the installation slot, the sealing strip is prevented from falling off and moving, which greatly improves the production efficiency, saves the amount of 3M glue, and saves costs.
[0014] The two ends of the skylight sealing strip have no corner joints and are punched to keep them consistent with the contour shape of the skylight glass and the sides of the car body, achieving a flush effect, greatly improving the appearance, ensuring a good appearance and beautiful visual effects, without the need for additional molds and packaging costs, and significantly reducing costs.

DETAILED DESCRIPTION
[0021] See also Figure 1-5 The utility model relates to a sealing structure for a car sunroof, comprising a sunroof glass 1, a PU edging 2 and a sunroof sealing strip 3. The sunroof glass 1 is provided with a PU edging 2 around its periphery, and the front and rear sides of the PU edging 2 are respectively connected to the sunroof sealing strip 3. The sunroof sealing strip 3 is in a strip shape, comprising an integrally formed T-shaped mounting portion 3.1 and a sealing lip 3.2. The PU edging 2 is provided with a mounting groove 2.1 corresponding to the T-shaped mounting portion 3.1, and the sunroof sealing strip 3 is clamped in the mounting groove 2.1 through the T-shaped mounting portion 3.1, and the sealing lip 3.2 is arranged outward.
[0022] The awning sealing strip 3 is provided with limiting notches 3.3 at both ends along the length direction, and the limiting notches 3.3 are arranged on the T-shaped mounting portion 3.1, and the mounting slot 2.1 is provided with protrusions 2.1.1 corresponding to the limiting notches 3.3, so that the awning sealing strip can be quickly positioned and installed, and the T-shaped mounting portion 3.1 can be prevented from moving in the length direction of the mounting slot 2.1.
