Description

Technical Field

[0001] The utility model relates to the field of skylights, in particular to a skylight sealing strip structure. Background Art

[0002] In the existing panoramic sunroof with front and rear glass, when the front glass is opened, the mechanical group lifts the arm and moves backward, which is easy to scratch the side sealing strip of the rear glass, affecting the sealing and service life of the side sealing strip. When the front glass is closed, the PU edge of the front glass presses down from the back to the front on the front sealing strip part of the rear glass, which is easy to cause the front sealing strip to loosen, affecting the middle sealing after the front and rear glasses are closed. Summary of the invention

[0003] The utility model provides a sunroof sealing strip structure which has a simple structure and can effectively improve the installation stability and sealing performance of a front sealing strip while taking into account the sealing performance and service life of a side sealing strip.

[0004] The technical solution adopted by the utility model is: a sunroof sealing strip structure, characterized in that it comprises a front sealing strip, a sealing strip corner connector and sealing strips on both sides, the front sealing strip comprises an integrally extruded front sealing strip sealing bubble and a front sealing strip sealing seat, the rear side of the front sealing strip sealing seat is glued to the front end of the rear glass PU edging, and the lower end of the front sealing strip sealing seat is supported on the rear glass PU edging, the side sealing strip comprises an integrally extruded side sealing strip sealing bubble, a side sealing strip sealing seat and a side sealing strip clamping joint, the two sides of the front sealing strip are respectively connected to the two side sealing strips by two sealing strip corner connectors for integral injection molding, the sealing strip corner connectors are injection molded into a 90-degree elbow structure with side and rear joints, the side joint is injection molded into a front sealing strip sealing bubble connected to the front sealing strip, and the rear joint is injection molded into a side sealing strip sealing bubble connected to the side sealing strip; upper and lower extrusion deformation points are correspondingly arranged on the upper and lower inner walls of the side sealing strip sealing bubble cavity, and the positions of the upper and lower extrusion deformation points are at the center of the width dimension of the side sealing strip sealing bubble or biased to one side of the side sealing strip sealing seat.

[0005] Glass fiber lines are arranged inside the front sealing strip sealing seat and the side sealing strip sealing seat along the length extension direction.

[0006] The front sealing strip sealing seat and the side sealing strip sealing seat are made of dense rubber.

[0007] The side sealing strip clamping joint is hollow inside.

[0008] The rear glass PU edging extends forward and into the middle drainage groove below the front glass. A supporting step is arranged inside the middle drainage groove, and the lower end of the front sealing strip sealing seat is supported on the supporting step.

[0009] The extrusion deformation point is a concave triangular groove or an arc groove.

[0010] The beneficial effects of the utility model are:

[0011] 1. The front sealing strip at the front end of the rear glass is glued on the rear side and supported on the PU edging of the rear glass. The overall installation structure is stable and firm. When the front glass is closed from back to front and downward, the pressure on the front sealing strip is shared by the supporting steps, which effectively prevents the front sealing strip from loosening due to long-term closing operations and improves the stability and sealing of use.

[0012] 2. The upper and lower extrusion deformation points are set inside the sealing bubble of the side sealing strip. When the front glass is opened, when the arm is moved backward and scratches the sealing bubble of the side sealing strip, the sealing bubble of the side sealing strip can effectively shrink to prevent damage, thereby having better sealing performance and ensuring service life.

[0013] 3. The front sealing strip and the side sealing strip are connected by injection molding of the sealing strip corner connectors, which is beneficial to the stability of the overall structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following is a further description with reference to the accompanying drawings.

[0020] Figure 1-4As shown: a sunroof sealing strip structure, including a front sealing strip 5, a sealing strip corner connector 8 and sealing strips 9 on both sides, the front sealing strip 5 includes an integrally extruded front sealing strip sealing bubble 6 and a front sealing strip sealing seat 7, the rear side of the front sealing strip sealing seat 6 is glued to the front end of the PU edging 2 of the rear glass 1, the PU edging 2 extends forward to extend into the middle drainage groove 3 under the front glass 15, the middle drainage groove 3 is provided with a supporting step 4, and the lower end of the front sealing strip sealing seat 7 is supported on the supporting step 4. The side sealing strip 9 includes an integrally extruded side sealing strip sealing bubble 10, a side sealing strip sealing seat 12 and a side sealing strip clamping joint 13. The two sides of the front sealing strip 9 are respectively connected to the sealing strips on both sides by two sealing strip corner connectors 8 and are integrally injection molded. The sealing strip corner connectors are injection molded into a 90-degree elbow structure with side and rear joints. The side joint is injection-molded in the front sealing strip sealing bubble to connect the front sealing strip, and the rear joint is injection-molded in the side sealing strip sealing bubble to connect the side sealing strip; upper and lower extrusion deformation points 11 are correspondingly arranged on the upper and lower inner walls of the cavity of the side sealing strip sealing bubble 10, and the extrusion deformation points are concave triangular grooves or arc grooves. The positions of the upper and lower extrusion deformation points are at the center of the width dimension of the side sealing strip sealing bubble or biased to one side of the side sealing strip sealing seat. Figure 3 As shown, when the side sealing strip sealing bubble 10 interferes with the mechanical assembly arm front bracket 16 of the front glass 15, due to the setting of the extrusion deformation point, the side sealing strip sealing bubble 10 can effectively retract the interference part to prevent scratch damage and reduction of sealing performance.
