[0003] The present application relates to the field of vehicle technology, and in particular to a vehicle window assembly and a vehicle. Background Art

[0004] As vehicle window functions diversify, some windows are now equipped with decorative ambient lighting to create a beautiful ambient lighting effect. Common windows with ambient lighting typically have a three-layer glass structure, including an ambient glass layer, a first glass layer, and a second glass layer stacked from the inside out. Light is emitted from the ambient glass into the vehicle interior.

[0005] The three-layer glass structure is both heavy and thick. To save space and reduce weight, some existing technical solutions have improved the window with ambient light to a two-layer glass structure, including a first glass layer and a second glass layer. By providing mounting grooves in the two-layer glass structure, the ambient light source is embedded in the two-layer glass structure. However, this method will destroy the integrity and shape regularity of the two-layer glass structure.

[0011] The light extraction device is used to extract the light transmitted in the first glass layer and emit it toward a side of the first glass layer facing the interior of the vehicle.

[0012] In one embodiment, the coupling input device is a light guide having a light incident surface and a light exit surface, and light emitted by the light source can enter the light guide through the light incident surface; the projection area of ​​the light exit surface facing the exterior of the vehicle is located within the first light reflecting layer, and light emitted through the light exit surface can enter the first glass layer from the side of the first glass layer facing the interior of the vehicle.

[0013] In one embodiment, the vehicle window assembly includes a second light reflecting layer, which is arranged on the light guide and located on a side of the light guide facing away from the first light reflecting layer, and the first light reflecting layer extends beyond the second light reflecting layer toward the light extraction device.

[0017] Along a plane direction parallel to the first glass layer, a distance between an inner edge of the shielding layer and an inner edge of the first light reflecting layer is 0.

[0018] In one embodiment, along a plane direction parallel to the first glass layer, a distance between an inner edge of the shielding layer and an outer edge of the light extraction device is greater than or equal to 0 and less than or equal to 30 mm.

[0019] In one embodiment, a distance between an inner edge of the shielding layer and an outer edge of the light extraction device is greater than or equal to 5 mm.

This achieves the desired ambient lighting effect while utilizing a glass structure to save space and reduce weight. Furthermore, the light source of the ambient light need not be embedded within the glass, ensuring the integrity and regularity of the glass structure.

Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0045] Referring to FIG1 , one embodiment of the present application provides a vehicle window assembly. The vehicle window assembly can be used as a sunroof, side windows, front windshield, rear windshield, or other vehicle features. The vehicle window assembly includes a first glass layer 200 , a light extraction device 410 , a shielding layer 420 , a first light reflecting layer 430 , an input coupling device 500 , and a light source 610 .

[0046] The shielding layer 420 and the light extraction device 410 are both located on the side of the first glass layer 200 facing the exterior of the vehicle, with the shielding layer 420 located in a peripheral area of ​​the light extraction device 410. It is understood that the shielding layer (commonly known as the black border) of glass is typically located in the edge area of ​​the glass. Therefore, the shielding layer 420 is located in the edge area of ​​the first glass layer 200, while the light extraction device 410 is located closer to the center of the first glass layer 200 relative to the shielding layer 420, so that the shielding layer 420 is located in a peripheral area of ​​the light extraction device 410.

[0047] The first light-reflecting layer 430 is positioned between the shielding layer 420 and the first glass layer 200. The coupling device 500 is disposed on the side of the first glass layer 200 facing the vehicle interior. The coupling device 500 couples light from a light source 610 into the first glass layer 200, allowing the light to pass through the first glass layer 200 and project onto the first light-reflecting layer 430. The light extraction device 410 is used to extract light transmitted through the first glass layer 200 and emit it toward the side of the first glass layer 200 facing the vehicle interior. The light source 610 can be an LED lamp or other type of light source.

[0048] 2 , in the aforementioned vehicle window assembly, light emitted from the light source 610 enters the coupling device 500. The coupling device 500 couples the light from the light source 610 into the first glass layer 200, allowing the light to pass through the first glass layer 200 and project onto the first light-reflecting layer 430. After being reflected by the first light-reflecting layer 430, the light re-enters the first glass layer 200, where it continues to travel within the first glass layer 200. As the light travels toward the light extraction device 410, the light extraction device 410 extracts the light transmitted through the first glass layer 200 and emits it toward the side of the first glass layer 200 facing the vehicle interior, thereby creating an ambient lighting effect.

[0049] As can be seen, the above-mentioned window assembly uses the coupling input device 500 to couple the light from the light source 610 into the first glass layer 200. By arranging the first reflective layer 430 between the shielding layer 420 and the first glass layer 200, the first reflective layer 430 reflects the light, preventing the light entering the first glass layer 200 from being absorbed by the shielding layer 420. Until the light is transmitted to the light extraction device 410, the light extraction device 410 extracts the light transmitted in the first glass layer 200 and emits it to the side of the first glass layer 200 facing the interior of the vehicle, thereby forming an ambient lighting effect. In this way, the lighting effect of the ambient light can be met, and the requirements of saving space and reducing weight are met by using a glass structure. Moreover, there is no need to embed the light source of the ambient light into the glass, ensuring the integrity and regularity of the shape of the glass structure.

[0050] The first light reflecting layer 430 is made of, for example, ink, which may be a coating layer, a printed layer, etc. The light extraction device 410 is made of, for example, ink, which may be a coating layer, a printed layer, etc.

[0051] It should be noted that the light extraction device 410 has a hollowed-out portion, while its non-hollowed-out portion has a specific pattern. Thus, the light extraction device 410 utilizes its non-hollowed-out portion to emit light in a specific pattern, thereby creating an ambient lighting effect. The first reflective layer 430 is used to reflect light to achieve light transmission, and it does not require a hollowed-out portion.

[0052] Referring to Figure 1 , in one embodiment, the coupling-in device 500 is a light guide having a light-emitting surface 520 and a light-entering surface 530. Light emitted by a light source 610 enters the light guide through the light-entering surface 530 and exits through the light-emitting surface 520. The projection area of ​​the light-emitting surface 520 facing the vehicle exterior is located within the first light-reflecting layer 430. Light emitted through the light-emitting surface 520 enters the first glass layer 200 from the side of the first glass layer 200 facing the vehicle interior.

[0053] Because the projection area of ​​the light emitting surface 520 facing the exterior of the vehicle is located within the first light reflecting layer 430 , light emitted from the light emitting surface 520 can pass through the first glass layer 200 and project onto the first light reflecting layer 430 after entering the first glass layer 200 . This allows the light to be reflected by the first light reflecting layer 430 , thereby preventing the light entering the first glass layer 200 from being absorbed by the shielding layer 420 .

[0054] The light guide member may be a glass block or the like and may be connected to the first glass layer 200 by bonding or the like.

[0055] In other embodiments, the coupling input device may also be other structures such as a grating.

[0056] 1 and 2 , in one embodiment, the vehicle window assembly includes a second light reflecting layer 440. The second light reflecting layer 440 is disposed on the light guide 500 and is located on a side of the light guide facing away from the first light reflecting layer 430. The first light reflecting layer 430 extends beyond the second light reflecting layer 430 toward the light extraction device 410.

[0057] Since the second light reflecting layer 440 is located on the side of the light guide member away from the first light reflecting layer 430 , the light reflected by the first light reflecting layer 430 passes through the first glass layer 200 and the light guide member and is projected onto the second light reflecting layer 440 .

[0058] Because the first light reflecting layer 430 extends beyond the second light reflecting layer 440 toward the light extraction device 410, as the light propagates toward the light extraction device 410, the light reflected by the second light reflecting layer 400 again passes through the light guide and the first glass layer 200 before being projected onto the portion of the first light reflecting layer 430 that extends beyond the second light reflecting layer 440. The light reflected by the portion of the first light reflecting layer 430 that extends beyond the second light reflecting layer 440 then strikes the interface of the first glass layer 200 near the vehicle interior. This interface of the first glass layer 200 then reflects back toward the light extraction device 410, allowing the light extraction device 410 to extract the light guided within the first glass layer 200. The reflection of light by the second light reflecting layer 440 reduces light loss after passing through the light guide.

[0059] 1 , in one embodiment, the light guide has a first surface (not shown) opposite to the light emitting surface 520. A light incident surface 530 connects the first surface and the light emitting surface 520. The light emitting surface 520 faces the first light reflecting layer 430. The second light reflecting layer 440 is disposed on the first surface.

[0060] 1 , in one embodiment, the light source 610 is closer to the outer edge of the first glass layer 200 than the light incident surface 530 , and the light source 610 is opposite to the light incident surface 530 , so that light emitted by the light source 610 can enter the light guide from the light incident surface 530 .

[0061] The shape of the light guide is not limited to the above embodiment. In other embodiments, the light emitting surface of the light guide faces the first light reflecting layer, and the light incident surface is adjacent to the light emitting surface and is arranged at an acute angle, so that the light emitted by the light source can also be incident from the light incident surface and emitted through the light emitting surface.

[0062] The material used for the second light reflecting layer 440 is, for example, ink, etc., which may be a coating layer, a printing layer, etc. The second light reflecting layer 420 is used to reflect light to achieve light propagation, and does not need to be provided with a hollow portion.

[0063] Referring to Figure 1 , in one embodiment, the vehicle window assembly further includes a second glass layer 100, which is stacked with the first glass layer 200. A shielding layer 420 and a light extraction device 410 are both located between the second glass layer 100 and the first glass layer 200. The first glass layer 200 is located on the side of the second glass layer 100 that faces the vehicle interior. The vehicle window assembly in this embodiment not only meets the requirements of ambient lighting, but also utilizes a two-layer glass structure to save space and reduce weight. Furthermore, the light source of the ambient lighting does not need to be embedded within the two-layer glass structure, thus ensuring the integrity and regularity of the two-layer glass structure.

[0064] Referring to Figure 1 , in one embodiment, a connecting layer 300 is disposed between the second glass layer 100 and the first glass layer 200 to connect the two. The specific structure and materials of the connecting layer 300 can be found in the prior art and will not be further described. A typical connecting layer 300 is, for example, an adhesive layer, which is used to bond the second glass layer 100 to the first glass layer 200.

[0065] In one embodiment, the light extraction device 410 is disposed on the surface of the first glass layer 200 facing the connection layer 300 .

[0066] Referring to FIG. 1 , in one embodiment, a distance A between the inner edge of the shielding layer 420 and the inner edge of the first light reflecting layer 430 along a plane parallel to the first glass layer 200 is less than 5 mm. The inner edge of the shielding layer 420 is closer to the light extraction device 410 than the inner edge of the first light reflecting layer 430. That is, the inner edge of the shielding layer 420 extends beyond the inner edge of the first light reflecting layer 430 toward the light extraction device 410. The inner edge of the shielding layer 420 is the edge of the shielding layer 420 on the side closest to the light extraction device 410 (also the edge of the shielding layer 420 closer to the center of the first glass layer 200). The inner edge of the first light reflecting layer 430 is the edge of the first light reflecting layer 430 on the side closest to the light extraction device 410 (also the edge of the first light reflecting layer 430 closer to the center of the first glass layer 200).

[0067] Since the inner edge of the shielding layer 420 extends beyond the inner edge of the first light reflecting layer 430 toward the light extraction device 410 , the shielding layer 420 occupies a relatively larger area, which can better shield the components of the first glass layer 200 that do not need to be exposed on the side facing the interior of the vehicle.

[0068] Since the distance A between the inner edge of the shielding layer 420 and the inner edge of the first light reflecting layer 430 is less than 5 mm, the distance A is small. Therefore, when the light propagates toward the direction close to the light extraction device 410 and leaves the inner edge of the first light reflecting layer 430, the shielding layer 420 can absorb as little light as possible at the distance A, thereby minimizing the dark stripes in the light reflected by the reflective pattern layer 410, avoiding the occurrence of obvious bright and dark stripe defects, and thus making the brightness of the light reflected by the reflective pattern layer 410 as uniform as possible.

[0069] In other embodiments, the distance between the inner edge of the shielding layer and the inner edge of the first light reflecting layer along the plane parallel to the first glass layer can also be zero. This can better prevent the absorption of light at the inner edge of the shielding layer, thereby more effectively avoiding the occurrence of obvious bright and dark stripes, and making the brightness of the light reflected by the reflective pattern layer as uniform as possible.

[0070] 1 , in one embodiment, a distance F between the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410 is greater than or equal to 0 and less than or equal to 30 mm along a plane parallel to the first glass layer 200. The outer edge of the light extraction device 410 is the edge of the light extraction device 410 closer to the shielding layer 420 (also the edge of the light extraction device 410 closer to the periphery of the first glass layer 200).

[0071] Since the distance F between the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410 is greater than or equal to 0, light disorder caused by the overlap of the shielding layer 420 and the light extraction device 410 can be avoided, thereby minimizing the occurrence of obvious bright and dark stripe defects.

[0072] Preferably, the distance F between the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410 is greater than 0, that is, the inner edge of the shielding layer 420 is spaced apart from the outer edge of the light extraction device 410. Because light absorption at the inner edge of the shielding layer 420 causes light loss, spacing the inner edge of the shielding layer 420 from the outer edge of the light extraction device 410 can prevent the absorption of light at the inner edge of the shielding layer 420 from affecting the outer edge of the reflection pattern of the light extraction device 410, thereby more effectively preventing light disturbance and avoiding the occurrence of obvious bright and dark stripe defects. Preferably, the distance F between the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410 is greater than or equal to 5 mm.

[0073] Because the inner edge of the shielding layer 420 is spaced apart from the outer edge of the light extraction device 410, a person inside the vehicle sees a blank area between the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410. To prevent this blank area from being too large, the distance F between the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410 is preferably limited to less than or equal to 30 mm.

[0074] As shown in FIG1 , in one embodiment, the vehicle window assembly further includes a housing 630 , which is connected to the first glass layer 200 . The coupling input device 500 and the light source 610 are located within the housing 630 to protect the coupling input device 500 and the light source 610 . The housing 630 is also used to block internal light to prevent it from affecting the pattern reflected by the reflective pattern layer 410 .

[0075] As shown in FIG1 , in one embodiment, a distance B between the inner edge of the shielding layer 420 and the inner edge of the light emitting surface 520 is greater than or equal to 8 mm and less than or equal to 40 mm along a plane parallel to the first glass layer 200. The inner edge of the light emitting surface 520 is the edge of the light emitting surface 520 that is closer to the light extraction device 410 (i.e., the edge of the light emitting surface 520 that is closer to the center of the first glass layer 200).

[0076] The distance B between the inner edge of the shielding layer 420 and the inner edge of the light exiting surface 520 defines the coverage area of ​​the inner edge of the shielding layer 420. The distance B is greater than or equal to 8 mm and less than or equal to 40 mm, which generally ensures that the coverage area of ​​the shielding layer 420 is sufficient to shield components on the side of the first glass layer 200 facing the vehicle interior that do not need to be exposed, such as the housing 630 and the components therein.

[0077] As shown in FIG1 , in one embodiment, the vehicle window assembly further includes a circuit board 620. The circuit board 620 is disposed on a side of the coupling input device 500 facing away from the first glass layer 200. The light source 610 is disposed on the circuit board 620. The circuit board 620 is located within a housing 630. Preferably, the circuit board 620 is parallel to the first glass layer 200.

[0078] In one embodiment, the circuit board 620 is located on a side of the coupling-in device 500 facing away from the second light reflecting layer 440 .

[0079] As shown in FIG. 1 , in one embodiment, the shielding layer 420 is disposed on the surface of the second glass layer 100 facing the connecting layer 300 , and the first light reflecting layer 430 is disposed between the shielding layer 420 and the connecting layer 300 .

[0080] When manufacturing a vehicle window assembly, the shielding layer 420 may be first disposed on the surface of the second glass layer 100 facing the connecting layer 300 , and then the first light reflecting layer 430 may be covered on the shielding layer 420 .

[0081] 3 , in another embodiment, the shielding layer 420 is disposed on the surface of the second glass layer 100 facing the connection layer 300 , and the first light reflecting layer 430 is disposed on the surface of the first glass layer 200 facing the connection layer 300 .

[0082] When manufacturing a vehicle window assembly, the shielding layer 420 may be disposed on the surface of the second glass layer 100 facing the connecting layer 300 , and the first glass layer 200 may be disposed on the surface facing the connecting layer 300 .

[0083] Referring to FIG. 4 , in another embodiment, a shielding layer 420 is disposed on a surface of the first glass layer 200 facing the exterior of the vehicle.

[0084] When manufacturing a vehicle window assembly, the first reflective layer 430 is disposed on the surface of the first glass layer 200 facing the exterior of the vehicle, and the shielding layer 420 is disposed on the surface of the first glass layer 200 facing the exterior of the vehicle, with the shielding layer 420 covering the first reflective layer 430.
