Abstract

A vehicle window assembly and a vehicle are provided in the disclosure. The vehicle window assembly includes multiple light guide strips spaced apart from each other, a vehicle window glass sheet, and a sealing box. The multiple light guide strips are arranged on one side surface of the vehicle window glass sheet, the sealing box is disposed at one side of each of the multiple light guide strips away from the vehicle window glass sheet, the sealing box defines grooves at positions respectively corresponding to the multiple light guide strips, and each of the multiple light guide strips is received in one of the grooves. The multiple light guide strips are received in the sealing box, the sealing box is directly fixed to the vehicle window glass sheet by the fixing member.

First claim

What is claimed is:

1. A vehicle window assembly, comprising a plurality of light guide strips spaced apart from each other, a vehicle window glass sheet, a sealing box, a bright strip, and a plurality of light-emitting modules, wherein
the plurality of light guide strips are arranged on one side surface of the vehicle window glass sheet, the sealing box is disposed at one side of each of the plurality of light guide strips away from the vehicle window glass sheet, the sealing box defines grooves at positions respectively corresponding to the plurality of light guide strips, and each of the plurality of light guide strips is received in one of the grooves;
the bright strip is opaque, the bright strip and the sealing box are opposite to each other to define a gap for accommodating the vehicle window glass sheet, wherein each of the plurality of light-emitting modules is arranged within an orthographic projection of the bright strip on the vehicle window glass sheet, each of the plurality of light-emitting modules defines a light-exiting opening, and the light-exiting opening corresponds to at least one of the plurality of light guide strips; and
the bright strip comprises a first bright portion and a second bright portion, wherein the plurality of light-emitting modules are arranged on the first bright portion, the second bright portion is connected to the first bright portion, the first bright portion and the second bright portion surround a space to define an accommodating region, and the plurality of light guide strips are arranged within the accommodating region.

2. The vehicle window assembly of claim 1 , wherein each of the plurality of light-emitting modules is configured to emit a light ray having a light intensity and color different from a light intensity and color of a light ray emitted by each of the other of the plurality of light-emitting modules.

3. The vehicle window assembly of claim 1 , further comprising a plurality of shielding members spaced apart from each other and a plurality of light-transmitting films spaced apart from each other, each of the plurality of shielding members is adjacent to and connected to one of the plurality of light-transmitting films, an orthographic projection of each of the plurality of light-transmitting films on the vehicle window glass sheet covers an orthographic projection of a corresponding light guide strip on the vehicle window glass sheet, and a combination of an orthographic projection of each of the plurality of shielding members on the vehicle window glass sheet and an orthographic projection of each of the plurality of light- transmitting films on the vehicle window glass sheet is covered by an orthographic projection of the sealing box on the vehicle window glass sheet.

4. The vehicle window assembly of claim 3 , wherein each of the plurality of light-transmitting films is configured to allow a light ray to pass through unidirectionally.

5. The vehicle window assembly of claim 1 , wherein the sealing box is integrally formed by injection molding; and each of the grooves has a semicircular shape, a rectangular shape, or a trapezoidal shape, or the grooves comprise various types of grooves among a semicircular groove, a rectangular groove, and a trapezoidal groove.

6. The vehicle window assembly of claim 1 , further comprising fixing members, wherein each of the fixing members is configured to fix the sealing box to the vehicle window glass sheet; and each of the fixing members is an optical adhesive, a 3M™ adhesive, or a polyurethane adhesive, or the fixing members comprise various types of fixing members among the optical adhesive, the 3M™ adhesive, and the polyurethane adhesive.

7. The vehicle window assembly of claim 1 , further comprising a hemming strip, wherein the hemming strip is separated from the light guide strip and is configured to fix the vehicle window glass sheet.

8. The vehicle window assembly of claim 1 , wherein an orthographic projection of the light guide strip on the vehicle window glass sheet extends from an orthographic projection of the bright strip on the vehicle window glass sheet.

9. A vehicle, comprising a frame and a vehicle window assembly mounted to the frame, wherein the vehicle window assembly comprises a plurality of light guide strips spaced apart from each other, a vehicle window glass sheet, a sealing box, a bright strip, and a plurality of light-emitting modules, wherein
the plurality of light guide strips are arranged on one side surface of the vehicle window glass sheet, the sealing box is disposed at one side of each of the plurality of light guide strips away from the vehicle window glass sheet, the sealing box defines grooves at positions respectively corresponding to the plurality of light guide strips, and each of the plurality of light guide strips is received in one of the grooves;
the bright strip is opaque, the bright strip and the sealing box are opposite to each other to define a gap for accommodating the vehicle window glass sheet, wherein each of the plurality of light-emitting modules is arranged within an orthographic projection of the bright strip on the vehicle window glass sheet, each of the plurality of light-emitting modules defines a light-exiting opening, and the light-exiting opening corresponds to at least one of the plurality of light guide strips;
the bright strip comprises a first bright portion and a second bright portion, wherein the plurality of light-emitting modules are arranged on the first bright portion, the second bright portion is connected to the first bright portion, the first bright portion and the second bright portion surround a space to define an accommodating region, and the plurality of light guide strips are arranged within the accommodating region.

10. The vehicle of claim 9 , wherein each of the plurality of light- emitting modules is configured to emit a light ray having a light intensity and color different from a light intensity and color of a light ray emitted by each of the other of the plurality of light-emitting modules.

11. The vehicle of claim 9 , further comprising a plurality of shielding members spaced apart from each other and a plurality of light-transmitting films spaced apart from each other, each of the plurality of shielding members is adjacent to and connected to one of the plurality of light-transmitting films, an orthographic projection of each of the plurality of light-transmitting films on the vehicle window glass sheet covers an orthographic projection of a corresponding light guide strip on the vehicle window glass sheet, and a combination of an orthographic projection of each of the plurality of shielding members on the vehicle window glass sheet and an orthographic projection of each of the plurality of light-transmitting films on the vehicle window glass sheet is covered by an orthographic projection of the sealing box on the vehicle window glass sheet.
