Abstract

A vehicle window assembly and a vehicle are provided. The vehicle window assembly includes a vehicle window glass and a light-guiding assembly. The vehicle window glass includes a first transparent plate, an intermediate layer, and a second transparent plate, and the second transparent plate defines a through-hole. The light-guiding assembly includes a light-guiding member and a fixing member. The light-guiding member is at least partially disposed in the through-hole, and a light-outputting surface of the light-guiding member is disposed facing towards an inner sidewall of the through-hole. The fixing member is disposed on a surface of the second transparent plate facing away from the first transparent plate, and the fixing member and the second transparent plate define an accommodating space configured to accommodate a light source. A light-emitting surface of the light source is disposed facing towards a light-inputting surface of the light-guiding member.

First claim

What is claimed is:

1. A vehicle window assembly, comprising a vehicle window glass and a light-guiding assembly, wherein the vehicle window glass comprises a first transparent plate, an intermediate layer, and a second transparent plate that are stacked successively, the first transparent plate is connected to the second transparent plate via the intermediate layer, and the second transparent plate defines a through-hole; the light-guiding assembly comprises a light-guiding member and a fixing member, the light-guiding member is at least partially disposed in the through-hole and fills the through-hole, and a light-outputting surface of the light-guiding member is disposed facing towards an inner sidewall of the through-hole; the fixing member is disposed on a surface of the second transparent plate facing away from the first transparent plate, and the fixing member and the second transparent plate define an accommodating space configured to accommodate a light source; a light-emitting surface of the light source is disposed facing towards a light-inputting surface of the light-guiding member; the vehicle window glass further comprises a light-sensitive member, the light-sensitive member is disposed corresponding to the light-outputting surface of the light-guiding member, to make light emitted by the light source incident to the light-sensitive member via the light-guiding member, and the light-sensitive member is configured to transmit the light into a vehicle;
wherein a surface of the light-guiding member close to the intermediate layer is entirely parallel to a surface of the intermediate layer close to the light-guiding member.

2. The vehicle window assembly of claim 1 , wherein the fixing member comprises a base plate, a housing, and at least one reinforcing rib, the light source is fixedly disposed on the base plate, and the base plate is fixedly connected to an inner sidewall of the housing via the at least one reinforcing rib.

3. The vehicle window assembly of claim 1 , wherein the light-guiding member comprises an optical sub-member, and the optical sub-member is configured to refract the light emitted by the light source to emit the light from the light-outputting surface of the light-guiding member.

4. The vehicle window assembly of claim 3 , wherein an angle between the light-outputting surface of the light-guiding member and the light-inputting surface of the light-guiding member ranges from 0° to 90°.

5. The vehicle window assembly of claim 3 , wherein the light-guiding member is provided with a reflective substance on at least part of an inner sidewall of the light-guiding member, and the reflective substance is configured to reflect light.

6. The vehicle window assembly of claim 3 , wherein reflectivity of a surface of the light-guiding member close to and facing towards the intermediate layer is greater than or equal to a reflection threshold.

7. The vehicle window assembly of claim 1 , wherein a shape of the through-hole is one or more of a rectangle, an ellipse, a circle, or any polygon.

8. The vehicle window assembly of claim 7 , wherein when the shape of the through-hole is a circle, a diameter of the through-hole is less than or equal to 50 mm.

9. The vehicle window assembly of claim 7 , wherein a shape of the light-guiding member disposed in the through-hole matches the shape of the through-hole.

10. The vehicle window assembly of claim 1 , wherein the light-guiding member comprises a supporting portion, and the supporting portion abuts against the inner sidewall of the through-hole.

11. The vehicle window assembly of claim 1 , wherein the light-guiding member disposed in the through-hole and the inner sidewall of the through-hole define a gap, and the gap is less than or equal to 2 mm.

12. The vehicle window assembly of claim 1 , wherein an extension length of the light-outputting surface of the light-guiding member extending beyond the through-hole is less than or equal to 5 mm.

13. The vehicle window assembly of claim 1 , wherein the through-hole is provided with a reflective substance on at least part of an inner sidewall of the through-hole, and the reflective substance is configured to reflect light.

14. The vehicle window assembly of claim 1 , wherein the vehicle window glass further comprises a reflective layer, the reflective layer is disposed on a surface of the intermediate layer close to the second transparent plate, and the reflective layer is disposed corresponding to the through-hole.

15. A vehicle, comprising a vehicle window assembly and a vehicle frame, wherein the vehicle window assembly is mounted on the vehicle frame; wherein the vehicle window assembly comprises a vehicle window glass and a light-guiding assembly, wherein the vehicle window glass comprises a first transparent plate, an intermediate layer, and a second transparent plate that are stacked successively, the first transparent plate is connected to the second transparent plate via the intermediate layer, and the second transparent plate defines a through-hole; the light-guiding assembly comprises a light-guiding member and a fixing member, the light-guiding member is at least partially disposed in the through-hole and fills the through-hole, and a light-outputting surface of the light-guiding member is disposed facing towards an inner sidewall of the through-hole; the fixing member is disposed on a surface of the second transparent plate facing away from the first transparent plate, and the fixing member and the second transparent plate define an accommodating space configured to accommodate a light source; a light-emitting surface of the light source is disposed facing towards a light-inputting surface of the light-guiding member; the vehicle window glass further comprises a light-sensitive member, the light-sensitive member is disposed corresponding to the light-outputting surface of the light-guiding member, to make light emitted by the light source incident to the light-sensitive member via the light-guiding member, and the light-sensitive member is configured to transmit the light into a vehicle;
