Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to window assemblies and vehicles. Background Technology

[0002] With the diversification of car window functions, some car windows are equipped with decorative ambient lighting to provide a beautiful ambient lighting effect. Common car windows with ambient lighting usually have a three-layer glass structure, including a first glass layer, a second glass layer, and an ambient glass layer stacked from the outside to the inside, with light shining into the car from the ambient glass.

[0003] The overall weight and thickness of a triple-glazed structure are relatively large. In order to save space and reduce weight, some existing technical solutions improve the window with ambient lighting to a double-glazed structure, including a first glass layer and a second glass layer. By setting mounting grooves in the double-glazed structure, the light source of the ambient light is embedded in the double-glazed structure. However, this method will destroy the integrity and shape regularity of the double-glazed structure. Summary of the Invention

[0004] Therefore, it is necessary to address the problem in existing technologies where the ambient light source of a car window is embedded within a two-layer glass structure, thereby compromising the integrity and shape regularity of the two-layer glass structure, and to provide a car window assembly and vehicle.

[0006] The first glass layer and the second glass layer are stacked together, the shielding layer and the light extraction device are both located between the first glass layer and the second glass layer, and the shielding layer is located in the peripheral area of ​​the light extraction device, and the first reflective layer is located between the shielding layer and the second glass layer;

[0007] The light guide is disposed on the side of the second glass layer away from the first glass layer. The light guide has an incident surface and an exit surface. Light emitted from the light source can enter the light guide through the incident surface. The projection area of ​​the exit surface toward the first glass layer is located within the first reflective layer. Light emitted through the exit surface can enter the second glass layer from the side of the second glass layer away from the first glass layer. The light extraction device is used to extract the light transmitted in the second glass layer and emit it toward the side of the second glass layer away from the first glass layer.

[0008] In one embodiment, the window assembly includes a second reflective layer disposed on the light guide and located on the side of the light guide opposite to the first reflective layer, wherein the first reflective layer extends beyond the second reflective layer in a direction toward the light extraction device.

[0009] In one embodiment, the light guide has a first surface disposed opposite to the light emitting surface, the second reflective layer is disposed on the first surface, the light emitting surface faces the first reflective layer, and the light incident surface connects the first surface and the light emitting surface.

[0010] In one embodiment, along a plane direction parallel to the first and second glass layers, the distance between the inner edge of the shielding layer and the inner edge of the first reflective layer is less than 5 mm, and the inner edge of the shielding layer is closer to the light extraction device than the inner edge of the first reflective layer; or,

[0011] Along a plane direction parallel to the first glass layer and the second glass layer, the distance between the inner edge of the shielding layer and the inner edge of the first reflective layer is 0.

[0012] In one embodiment, along a plane direction parallel to the first glass layer and the second glass layer, the distance between the inner edge of the shielding layer and the outer edge of the light extraction device is greater than or equal to 0 and less than or equal to 30 mm.

[0013] In one embodiment, the distance between the inner edge of the shielding layer and the outer edge of the light extraction device is greater than or equal to 5 mm.

[0014] In one embodiment, the window assembly further includes a housing connected to the second glass layer, and the light guide and the light source are located within the housing.

[0016] In one embodiment, the window assembly further includes a circuit board disposed on the side of the light guide away from the second glass layer, the light source being disposed on the circuit board, and the circuit board being located within the housing.

[0017] In one embodiment, a connecting layer for connecting the first glass layer and the second glass layer is provided between the two.

[0018] In one embodiment, the shielding layer is disposed on the surface of the first glass layer facing the connecting layer, and the first reflective layer is disposed between the shielding layer and the connecting layer.

[0021] A vehicle comprising the window assembly described in any of the above embodiments.

[0022] The aforementioned window assembly and vehicle utilize a light guide to direct light from a light source into the second glass layer. By placing a first reflective layer between the shielding layer and the second glass layer, the reflection of light by the first reflective layer prevents the light entering the second glass layer from being absorbed by the shielding layer. The light is then guided to a light extraction device, which extracts the light transmitted through the second glass layer and projects it out onto the side of the second glass layer opposite to the first glass layer, thus creating an ambient lighting effect. This design satisfies the requirements for ambient lighting while using a two-layer glass structure to save space and reduce weight. Furthermore, it eliminates the need to embed the ambient light source within the two-layer glass structure, ensuring the integrity and regularity of the two-layer glass structure.

[0034] Please refer to Figure 1 This application provides a vehicle window assembly in one embodiment. The vehicle window assembly can be used as a sunroof, side window, windshield, rear windshield, etc. of a vehicle. The vehicle window assembly includes: a first glass layer 100, a second glass layer 200, a light extraction device 410, a shielding layer 420, a first reflective layer 430, a light guide 500, and a light source 610.

[0035] The first glass layer 100 and the second glass layer 200 are stacked. The second glass layer 200 is located on the side of the first glass layer 100 facing the vehicle interior space. Both the shielding layer 420 and the light extraction device 410 are located between the first glass layer 100 and the second glass layer 200, with the shielding layer 420 located in the peripheral area of ​​the light extraction device 410. Understandably, the shielding layer (commonly known as the black edge) of the glass is usually located in the edge area of ​​the glass. Therefore, the shielding layer 420 is located in the edge area between the first glass layer 100 and the second glass layer 200, while the light extraction device 410 is located in a more central area between the first glass layer 100 and the second glass layer 200 relative to the shielding layer 420, thus the shielding layer 420 is located in the peripheral area of ​​the light extraction device 410.

[0036] The first reflective layer 430 is located between the shielding layer 420 and the second glass layer 200. A light guide 500 is disposed on the side of the second glass layer 200 facing away from the first glass layer 100, i.e., the light guide 500 is located on the side of the second glass layer 200 facing the vehicle interior space. The light guide 500 has a light-emitting surface 520 and a light-incident surface 530. Light emitted from the light source 610 can enter the light guide 500 through the light-incident surface 530 and exit from the light-emitting surface 520. The projection area of ​​the light-emitting surface 520 towards the first glass layer 100 is located within the first reflective layer 430, and light emitted through the light-emitting surface 520 can enter the second glass layer 200 from the side facing away from the first glass layer 100. A light extraction device 410 is used to extract the light transmitted in the second glass layer 200 and emit it towards the side of the second glass layer 200 facing away from the first glass layer 100. The light source 610 can be an LED lamp or other types of light source.

[0037] Combination Figure 2 In the aforementioned window assembly, light emitted from the light source 610 enters the light guide 500 from the light-incident surface 530 and exits from the light-exiting surface 520 of the light guide 500. Since the projection area of ​​the light-exiting surface 520 towards the first glass layer 100 is located within the first reflective layer 430, the light emitted from the light-exiting surface 520 enters the second glass layer 200 from the side away from the first glass layer 100 and can then pass through the second glass layer 200 and be projected onto the first reflective layer 430. The light reflected by the first reflective layer 430 then re-enters the second glass layer 200, thus continuing to propagate within it. As the light propagates towards the light extraction device 410, the light extraction device 410 extracts the light propagated within the second glass layer 200 and emits it from the side of the second glass layer 200 away from the first glass layer 100, thereby creating the ambient lighting effect.

[0038] Therefore, the aforementioned window assembly utilizes the light guide 500 to guide the light from the light source 610 into the second glass layer 200. By placing the first reflective layer 430 between the shielding layer 420 and the second glass layer 200, the reflection of light by the first reflective layer 430 prevents the light entering the second glass layer 200 from being absorbed by the shielding layer 420. The light is then transmitted to the light extraction device 410, which extracts the light transmitted through the second glass layer 200 and emits it towards the side of the second glass layer 200 away from the first glass layer 100, thus creating an ambient lighting effect. In this way, the ambient lighting effect is achieved while the two-layer glass structure meets the requirements of space saving and weight reduction. Furthermore, the light source of the ambient light does not need to be embedded within the two-layer glass structure, ensuring the integrity and shape regularity of the two-layer glass structure.

[0039] The first reflective layer 430 is made of materials such as ink, and can be a coating, printed layer, etc. The light extraction device 410 is made of materials such as ink, and can be a coating, printed layer, etc. The light guide 500 can be a structure such as a glass block. The light guide 500 can be connected to the second glass layer 200 by means of bonding or other methods.

[0040] 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 shape. Thus, the light extraction device 410 can emit light in a specific pattern using its non-hollowed-out portion, thereby creating the luminous effect of an ambient light. The first reflective layer 430 is used to reflect light to achieve light propagation, and it does not need to have a hollowed-out portion.

[0041] Please refer to Figure 1 Combination Figure 2 In one embodiment, the window assembly includes a second reflective layer 440. The second reflective layer 440 is disposed on the light guide 500 and located on the side of the light guide 500 opposite to the first reflective layer 430. The first reflective layer 430 extends beyond the second reflective layer 430 in a direction close to the light extraction device 410.

[0042] Since the second reflective layer 440 is located on the side of the light guide 500 away from the first reflective layer 430, the light reflected by the first reflective layer 430 passes through the second glass layer 200 and the light guide 500 and is projected onto the second reflective layer 440.

[0043] Since the first reflective layer 430 extends beyond the second reflective layer 440 in the direction closer to the light extraction device 410, as light propagates towards the light extraction device 410, the light reflected by the second reflective layer 400 passes again through the light guide 500 and the second glass layer 200 and is projected onto the extended portion of the first reflective layer 430 (i.e., the portion of the first reflective layer 430 that extends beyond the second reflective layer 440). The light reflected by the extended portion of the first reflective layer 430 is then projected onto the interface of the second glass layer 200 away from the first glass layer 100, and reflected by this interface onto the light extraction device 410, thereby enabling the light extraction device 410 to extract the light transmitted within the second glass layer 200. By utilizing the reflection of light by the second reflective layer 440, the loss of light after passing through the light guide 500 can be reduced.

[0044] Please refer to Figure 1 In one embodiment, the light guide 500 has a first surface (not shown) disposed opposite to the light emitting surface 520. The light incident surface 530 connects the first surface and the light emitting surface 520, the light emitting surface 520 faces the first reflective layer 430, and the second reflective layer 440 is disposed on the first surface.

[0045] Please refer to Figure 1In one embodiment, the light source 610 is closer to the outer edge of the second glass layer 200 relative to the light incident surface 530, and the light source 610 is opposite to the light incident surface 530, so that the light emitted by the light source 610 can enter the light guide 500 from the light incident surface 530.

[0046] The shape of the light guide is not limited to the above embodiments. In other embodiments, the light-emitting surface of the light guide faces the first reflective layer, while the light-incident surface is adjacent to the light-emitting surface and is set at an acute angle. In this way, the light emitted by the light source can also enter from the light-incident surface and exit through the light-emitting surface.

[0047] The material used for the second reflective layer 440 is, for example, ink, which can be a coating, a printed layer, etc. The second reflective layer 420 is used to reflect light to achieve light propagation, and it does not need to have any cutouts.

[0048] refer to Figure 1 In one embodiment, a connecting layer 300 for connecting the first glass layer 100 and the second glass layer 200 is provided. The specific structure and material of the connecting layer 300 can be found in existing technology and will not be described in detail here. A common example of a connecting layer 300 is an adhesive layer used to bond the first glass layer 100 to the second glass layer 200.

[0049] In one embodiment, the light extraction device 410 is disposed on the surface of the second glass layer 200 facing the connecting layer 300.

[0050] refer to Figure 1 In one embodiment, along a plane direction parallel to the first glass layer 100 and the second glass layer 200, the distance A between the inner edge of the shielding layer 420 and the inner edge of the first reflective layer 430 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 reflective layer 430, that is, the inner edge of the shielding layer 420 extends beyond the inner edge of the first reflective layer 430 in a direction closer to the light extraction device 410. The inner edge of the shielding layer 420 is the edge of the shielding layer 420 closer to the light extraction device 410 (which is also the edge of the shielding layer 420 closer to the center of the second glass layer 200). The inner edge of the first reflective layer 430 is the edge of the first reflective layer 430 closer to the light extraction device 410 (which is also the edge of the first reflective layer 430 closer to the center of the second glass layer 200).

[0051] Since the inner edge of the shielding layer 420 extends beyond the inner edge of the first reflective layer 430 in the direction closer to the light extraction device 410, the area occupied by the shielding layer 420 is relatively larger, which can better shield the components of the second glass layer 200 that do not need to be exposed on the side away from the first glass layer 100.

[0052] Since the distance A between the inner edge of the shielding layer 420 and the inner edge of the first reflective layer 430 is less than 5mm, this distance A is small. Therefore, when light propagates towards the light extraction device 410 and leaves the inner edge of the first reflective layer 430, the shielding layer 420 can absorb as little light as possible at the distance A. This can minimize the dark stripes in the light reflected by the reflective pattern layer 410, avoid obvious bright and dark stripe defects, and make the brightness of the light reflected by the reflective pattern layer 410 as uniform as possible.

[0053] In other embodiments, the distance between the inner edge of the shielding layer and the inner edge of the first reflective layer can also be zero along a plane direction parallel to the first and second glass layers. This can better prevent light absorption at the inner edge of the shielding layer, thereby more effectively avoiding obvious bright and dark stripe defects and making the brightness of the light reflected by the reflective pattern layer as uniform as possible.

[0054] refer to Figure 1 In one embodiment, along a plane direction parallel to the first glass layer 100 and the second glass layer 200, 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 and less than or equal to 30 mm. The outer edge of the light extraction device 410 is the edge of the light extraction device 410 closer to the shielding layer 420 (which is also the edge of the light extraction device 410 closer to the periphery of the second glass layer 200).

[0055] 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, the light disturbance caused by the overlap between the shielding layer 420 and the light extraction device 410 can be avoided, thereby minimizing the occurrence of obvious bright and dark stripe defects.

[0056] 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 and the outer edge of the light extraction device 410 are spaced apart. Since light absorption at the inner edge of the shielding layer 420 can cause light loss, spaced-apart arrangement of the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410 can prevent light absorption at the inner edge of the shielding layer 420 from affecting the outer edge of the reflection pattern of the light extraction device 410, thus more effectively preventing light disturbance and avoiding 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.

[0057] Because the inner edge of the shielding layer 420 is spaced apart from the outer edge of the light extraction device 410, the area between the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410 is a blank area when viewed by occupants inside the vehicle. To avoid this blank area being too large, preferably, the distance F between the inner edge of the shielding layer 420 and the outer edge of the light extraction device 410 can be limited to less than or equal to 30 mm.

[0058] like Figure 1 As shown, in one embodiment, the window assembly further includes a housing 630 connected to the second glass layer 200. The light guide 500 and the light source 610 are located inside the housing 630 to protect the light guide 500 and the light source 610. The housing 630 is used to block internal light to prevent it from affecting the pattern reflected by the reflective pattern layer 410.

[0059] like Figure 1 As shown, in one embodiment, along a plane direction parallel to the first glass layer 100 and the second glass layer 200, the 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. The inner edge of the light-emitting surface 520 is the edge of the light-emitting surface 520 closer to the light extraction device 410 (that is, the edge of the light-emitting surface 520 closer to the center of the second glass layer 200).

[0060] The distance B between the inner edge of the shielding layer 420 and the inner edge of the light-emitting 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 can basically ensure that the coverage area of ​​the shielding layer 420 is sufficient to shield the unexposed components of the second glass layer 200 on the side opposite to the first glass layer 100, such as the housing 630 and its internal components.

[0061] like Figure 1 As shown, in one embodiment, the window assembly further includes a circuit board 620, which is disposed on the side of the light guide 500 opposite to the second glass layer 200. A light source 610 is disposed on the circuit board 620, and the circuit board 620 is located within the housing 630. Preferably, the circuit board 620 is parallel to the second glass layer 200 and the first glass layer 100.

[0062] In one embodiment, the circuit board 620 is located on the side of the light guide 500 opposite to the second reflective layer 440.

[0063] like Figure 1 As shown, in one embodiment, a shielding layer 420 is disposed on the surface of the first glass layer 100 facing the connecting layer 300, and a first reflective layer 430 is disposed between the shielding layer 420 and the connecting layer 300.

[0064] When processing the window assembly, the shielding layer 420 can be first placed on the surface of the first glass layer 100 facing the connecting layer 300, and then the first reflective layer 430 can be covered on the shielding layer 420.

[0065] Please refer to Figure 3 In another embodiment, the shielding layer 420 is disposed on the surface of the first glass layer 100 facing the connecting layer 300, and the first reflective layer 430 is disposed on the surface of the second glass layer 200 facing the connecting layer 300.

[0066] When processing the window assembly, the shielding layer 420 can be placed on the surface of the first glass layer 100 facing the connecting layer 300, and the second glass layer 200 can be placed on the surface facing the connecting layer 300.

[0067] Please refer to Figure 4 In another embodiment, the shielding layer 420 is disposed on the surface of the second glass layer 200 facing the connecting layer 300.

[0068] When processing the window assembly, the first reflective layer 430 is disposed on the surface of the second glass layer 200 facing the connecting layer 300, and then the shielding layer 420 is disposed on the surface of the second glass layer 200 facing the connecting layer 300, so that the shielding layer 420 covers the first reflective layer 430.

[0069] Another embodiment of this application provides a vehicle including any of the window assemblies described in the above embodiments.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
