Abstract

The present disclosure relates to an encapsulation assembly for automotive glass including first glass, an encapsulation component, a plastic guiding rail, a sealing strip, and a decorative layer. Second glass is slidably connected in the plastic guiding rail. One end of the plastic guiding rail is fixedly connected to an edge of the first glass by means of integrally injection-molding the encapsulation component. The other end of the plastic guiding rail is provided with a guiding groove for guiding sliding of the second glass. The guiding groove includes an upper wall and a lower wall opposite to each other. The sealing strip is fixed between the upper wall and the lower wall. The second glass and the sealing strip slidably cooperate. A side of the plastic guiding rail facing outside of a vehicle is provided with the decorative layer by injection molding.

First claim

What is claimed is:

1. An encapsulation assembly for automotive glass, comprising a first glass, an encapsulation component, a plastic guiding rail, a sealing strip, and a decorative layer, wherein a second glass is slidably connected in the plastic guiding rail, characterized in that, one end of the plastic guiding rail is fixedly connected to an edge of the first glass by means of integrally injection-molding the encapsulation component; an other end of the plastic guiding rail is provided with a guiding groove for guiding sliding of the second glass; the guiding groove includes an upper wall and a lower wall opposite to each other; the sealing strip is fixed between the upper wall and the lower wall; the second glass and the sealing strip slidably cooperate; a side of the plastic guiding rail facing outside of a vehicle is provided with the decorative layer by injection molding; and a gap between the decorative layer and the encapsulation component is greater than 0.5 mm; the decorative layer is merely in contact with the upper wall.

2. The encapsulation assembly for automotive glass according to claim 1 , wherein the plastic guiding rail is made of copolymer of acrylonitrile, butadiene, and styrene (ABS), ABS+ glass fiber (GF), ABS+ polycarbonate (PC)+GF, or PC+GF, and the decorative layer is made of polymethyl methacrylate (PMMA).

3. The encapsulation assembly for automotive glass according to claim 1 , wherein the encapsulation component is made of thermoplastic elastomer (TPE) or polyvinyl chloride (PVC).

4. The encapsulation assembly for automotive glass according to claim 1 , wherein the decorative layer has a thickness of 1.5 mm to 3 mm.

5. The encapsulation assembly for automotive glass according to claim 1 , wherein the upper wall has a thickness of 1.5 mm to 3 mm, and the lower wall has a thickness of 1.5 mm to 3 mm.

6. The encapsulation assembly for automotive glass according to claim 1 , wherein the decorative layer covers an upper edge and a side edge of the upper wall, and a lower surface of the decorative layer covering the side edge of the upper wall is flush with a lower surface of the upper wall.

7. The encapsulation assembly for automotive glass according to claim 1 , wherein a lower edge and a side edge of the lower wall are covered by the encapsulation component, and an upper surface of the encapsulation component covering the side edge of the lower wall is flush with an upper surface of the lower wall.

8. The encapsulation assembly for automotive glass according to claim 7 , wherein a portion of the encapsulation component covering a side of the first glass facing outside of the vehicle has a thickness of 1.5 mm to 3 mm.

9. The encapsulation assembly for automotive glass according to claim 7 , wherein another portion of the encapsulation component covering the lower edge of the lower wall has a thickness of 1.5 mm to 3 mm.

10. An encapsulation assembly for automotive glass, comprising a first glass, an encapsulation component, a plastic guiding rail, a sealing strip, and a decorative layer, wherein a second glass is slidably connected in the plastic guiding rail, characterized in that, one end of the plastic guiding rail is fixedly connected to an edge of the first glass by means of integrally injection-molding the encapsulation component; an other end of the plastic guiding rail is provided with a guiding groove for guiding sliding of the second glass; the guiding groove includes an upper wall and a lower wall opposite to each other; the sealing strip is fixed between the upper wall and the lower wall; the second glass and the sealing strip slidably cooperate; a side of the plastic guiding rail facing outside of a vehicle is provided with the decorative layer by injection molding; the decorative layer is in direct contact with an entire upper surface of the upper wall.

11. The encapsulation assembly for automotive glass according to claim 10 , wherein the plastic guiding rail is made of copolymer of acrylonitrile, butadiene, and styrene (ABS), ABS+ glass fiber (GF), ABS+ polycarbonate (PC)+GF, or PC+GF, and the decorative layer is made of polymethyl methacrylate (PMMA).

12. The encapsulation assembly for automotive glass according to claim 10 , wherein the encapsulation component is made of thermoplastic elastomer (TPE) or polyvinyl chloride (PVC).

13. The encapsulation assembly for automotive glass according to claim 10 , wherein the decorative layer has a thickness of 1.5 mm to 3 mm.

14. The encapsulation assembly for automotive glass according to claim 10 , wherein the upper wall has a thickness of 1.5 mm to 3 mm, and the lower wall has a thickness of 1.5 mm to 3 mm.

15. The encapsulation assembly for automotive glass according to claim 10 , wherein the decorative layer covers an upper edge and a side edge of the upper wall, and a lower surface of the decorative layer covering the side edge of the upper wall is flush with a lower surface of the upper wall.

16. The encapsulation assembly for automotive glass according to claim 10 , wherein a lower edge and a side edge of the lower wall are covered by the encapsulation component, and an upper surface of the encapsulation component covering the side edge of the lower wall is flush with an upper surface of the lower wall.

17. The encapsulation assembly for automotive glass according to claim 16 , wherein a portion of the encapsulation component covering a side of the first glass facing outside of the vehicle has a thickness of 1.5 mm to 3 mm.

18. The encapsulation assembly for automotive glass according to claim 17 , wherein another portion of the encapsulation component covering the lower edge of the lower wall has a thickness of 1.5 mm to 3 mm.
