[0020] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0021] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0022] In vehicles, ambient lights are often mounted on a glass substrate and covered with a cover plate. However, the cover plate cannot completely block the light emitted by the ambient light, resulting in a grainy appearance; the cover plate is also prone to poor adhesion, affecting the fit and causing bright lines to appear between the cover plate and the glass substrate, as well as reflections at the edges of the cover plate, which affects the lighting effect.

[0023] Furthermore, the cover plate is usually bonded to the glass substrate using foam. In dark environments, the foam has large pores and gaps, allowing light from the ambient light to easily pass through. Also, due to the rebound force of the foam, the cover plate cannot completely adhere to the glass substrate, resulting in light leakage and affecting the lighting effect.

[0024] In view of this, in order to solve the above problems, please refer to the following: Figures 1-3 This embodiment provides a light-emitting glass assembly 1, which includes a glass substrate 11, a light-emitting component 12, and a cover plate 13. A receiving cavity is formed between the glass substrate 11 and the cover plate 13, and the light-emitting component 12 is disposed in the receiving cavity.

[0025] The cover plate 13 includes an overlapping portion 131 at one end of the cover plate 13 and a first adhesive portion 132 adjacent to the overlapping portion 131. The overlapping portion 131 is sealed against the glass substrate 11, and the first adhesive portion 132 is bonded to the glass substrate 11.

[0026] Optionally, when the light-emitting glass assembly 1 is applied to a vehicle, the glass substrate 11 can be a windshield, a side window, a sunroof, a corner window, or a rear windshield, etc.

[0027] Optionally, the glass substrate 11 can be a single piece of glass or a laminated glass. Further optionally, the glass substrate 11 includes a first glass plate 111, an adhesive layer 112, and a second glass plate 113 stacked sequentially, with the adhesive layer 112 bonding the first glass plate 111 and the second glass plate 113 together.

[0028] The cover plate 13 is used to protect the light-emitting component 12, to block the light emitted by the light-emitting component 12, to perform shading, and to improve the light utilization rate of the light-emitting component 12. The cover plate 13 is disposed on the surface of the glass substrate 11, and a cavity is formed between the cover plate 13 and the glass substrate 11. The cover plate 13 is made of an opaque material; optionally, the material of the cover plate 13 is selected from at least one of EPDM, PVC, PU, ​​and PP. Optionally, the cover plate 13 is directly fixed to the glass substrate 11, or the cover plate 13 is indirectly fixed to the glass substrate 11 through other components. Optionally, the connection method between the cover plate 13 and the glass substrate 11 is adhesive bonding, sealing contact, etc.

[0029] The cover plate 13 includes an overlapping portion 131 and a first adhesive portion 132. The overlapping portion 131 is located at the edge of the cover plate 13 and is capable of sealing against the glass substrate 11. Specifically, the overlapping portion 131 has a sealing surface facing the glass substrate 11, and the sealing surface tightly abuts against the glass substrate 11; in other words, the sealing surface is in close contact with the glass substrate 11. The first adhesive portion 132 is disposed adjacent to the overlapping portion 131, and the first adhesive portion 132 is farther away from the edge of the cover plate 13 than the overlapping portion 131.

[0030] The first adhesive portion 132 is bonded to the glass substrate 11 by a first adhesive 1321, which blocks light from the light-emitting component 12. The first adhesive 1321 is made of an opaque material, optionally selected from at least one of 3M adhesive, foam, PU adhesive, PVC, foam adhesive, rubber, EPDM adhesive, and plastic. This embodiment uses an opaque first adhesive 1321, which allows the cover plate 13 to better block the light emitted by the light-emitting component 12, preventing a grainy appearance and light leakage.

[0031] The light-emitting component 12 is used to emit light. The light from the self-emitting component 12 can pass through the glass substrate 11. For example, the light-emitting component 12 can be used as an ambient light, decorative light, indicator light, etc.

[0032] In summary, the light-emitting glass assembly 1 provided in this embodiment, by providing an overlapping portion 131 at the edge of the cover plate 13 and cooperating with a first adhesive portion 132, can fix the cover plate 13 to the glass substrate 11 and block at least part of the light from the self-emitting component 12. The overlapping portion 131 can abut against the sealed glass substrate 11 to further block the light from the self-emitting component 12, thereby preventing light leakage from the cover plate 13, avoiding local light leakage, improving the light emission uniformity of the light-emitting component 12, and improving the light emission effect of the light-emitting component 12.

[0033] Please refer to this as well. Figures 1-3In one embodiment, the cover plate 13 further includes a second adhesive portion 133 disposed on the side of the first adhesive portion 132 opposite to the overlapping portion 131, and the second adhesive portion 133 is bonded to the light-emitting component 12.

[0034] The second adhesive portion 133 is disposed adjacent to the first adhesive portion 132, and the second adhesive portion 133 is farther away from the edge of the cover plate 13 compared to the first adhesive portion 132. The second adhesive portion 133 is bonded to the light-emitting component 12 by a second adhesive 1331. The second adhesive 1331 can be made of a light-transmitting or opaque material. Optionally, the material of the second adhesive 1331 is selected from at least one of 3M adhesive, foam, PU adhesive, PVC, foam adhesive, rubber, EPDM adhesive, and plastic.

[0035] In summary, by providing a second adhesive portion 133 on the cover plate 13, this embodiment not only improves the connection performance between the cover plate 13 and the light-emitting component 12, reduces the probability of the cover plate 13 falling off, and improves the reliability of the light-emitting glass assembly 1, but also helps to improve the adhesion between the cover plate 13 and the glass substrate 11, further avoids local light leakage, further improves the light emission uniformity of the light-emitting component 12, and further improves the light emission effect of the light-emitting component 12.

[0036] Please refer to this as well. Figures 1-3 In one embodiment, the cover plate 13 further includes a third adhesive portion 134 disposed on the side of the second adhesive portion 133 opposite to the first adhesive portion 132, the third adhesive portion 134 being bonded to the glass substrate 11, and the light-emitting component 12 being disposed between the first adhesive portion 132 and the third adhesive portion 134.

[0037] The third adhesive portion 134 is disposed opposite to the overlapping portion 131. The third adhesive portion 134 is disposed at one end of the cover plate 13, and the overlapping portion 131 is disposed at the other end of the cover plate 13. The third adhesive portion 134 and the first adhesive portion 132 are disposed on opposite sides of the second adhesive portion 133, and the light-emitting component 12 is disposed between the first adhesive portion 132 and the third adhesive portion 134.

[0038] The third adhesive portion 134 is bonded to the glass substrate 11 by a third adhesive 1341. The third adhesive 1341 is used to block the light from the self-luminous component 12. The third adhesive 1341 is made of an opaque material. Optionally, the material of the third adhesive 1341 is selected from at least one of 3M adhesive, foam, PU adhesive, PVC, foam adhesive, rubber, EPDM adhesive, and plastic.

[0039] In summary, this embodiment provides a third adhesive portion 134 on the cover plate 13, which firmly fixes the cover plate 13 to the glass substrate 11. The third adhesive portion 134, in conjunction with the first adhesive portion 132, further improves the connection performance between the cover plate 13 and the glass substrate 11, which is beneficial to improving the adhesion between the cover plate 13 and the glass substrate 11, further avoiding local light leakage, further improving the light emission uniformity of the light-emitting component 12, and further improving the light emission effect of the light-emitting component 12.

[0040] Please refer to this as well. Figures 1-3 In one embodiment, the light-emitting component 12 includes a light guide portion 121 and a light-emitting portion 122. The light guide portion 121 is closer to the glass substrate 11 than the light-emitting portion 122. The light-emitting portion 122 is used to emit light, and the light guide portion 121 is used to guide the light.

[0041] The light-emitting component 12 includes a light guide 121, a light-emitting part 122, and a circuit board 123. The circuit board 123 is electrically connected to the light-emitting part 122 and is used to control the operation of the light-emitting part 122. The light-emitting part 122 emits light, and the light guide 121 receives the light from the light-emitting part 122 and guides the light to the glass substrate 11. The light guide 121 is disposed on the surface of the glass substrate 11, and the light-emitting part 122 is disposed on the side of the light guide 121. The side of the light guide 121 is bent to connect the light guide 121 away from the surface of the glass substrate 11, and the circuit board 123 is disposed on the surface of the light guide 121 away from the glass substrate 11. Optionally, the circuit board 123 is bonded to the light guide 121.

[0042] The light guide 121 is made of a transparent material with good light conductivity. Optionally, the material of the light guide 121 is selected from at least one of glass, acrylic, and plastic. For example, the light guide 121 is made of ultra-clear glass to ensure that the light guide 121 has good optical performance.

[0043] Optionally, an optical adhesive 1211 is provided between the light guide portion 121 and the glass substrate 11, and the light guide portion 121 and the glass substrate 11 are bonded together by the optical adhesive 1211. The optical adhesive 1211 has good refractive and transmission properties and sufficient adhesive strength. For example, the optical adhesive 1211 can be divided into two types: one is an adhesive that is cured by ultraviolet light, and the other is an adhesive that is cured by infrared light.

[0044] Optionally, the light guide portion 121 is bonded to the glass substrate 11 by a damming adhesive and an optical adhesive 1211, with the damming adhesive and the optical adhesive 1211 disposed in the same layer.

[0045] The number of light-emitting parts 122 is at least one, and the light-emitting parts 122 are disposed on the periphery of the light guide part 121. Optionally, the light-emitting parts 122 are selected from LED lamps, OLED lamps, laser light sources, quantum dot light-emitting parts 122, fluorescent lamps, etc.

[0046] In summary, this embodiment improves the light emission uniformity and thus enhances the light emission effect of the light emission component 12 by providing a light-emitting component 12 composed of a light guide 121 and a light-emitting component 122, so that the light guide 121 and the light-emitting component 122 cooperate with each other.

[0047] Please refer to this as well. Figures 1-3 In one embodiment, the second adhesive portion 133 is bonded to the light guide portion 121, and the light-emitting portion 122 is disposed on the side of the light guide portion 121 near the third adhesive portion 134.

[0048] Optionally, the second adhesive portion 133 is bonded to the surface of the light guide portion 121 facing away from the glass substrate 11 by a second adhesive 1331. The light guide portion 121 is closer to the first adhesive portion 132 than the light-emitting portion 122.

[0049] First, this embodiment further defines the second adhesive portion 133 to bond the light guide portion 121, thus avoiding the second adhesive portion 133 from being bonded to the light-emitting portion 122 and affecting its light-emitting effect. Second, by defining the position of the light-emitting portion 122, this embodiment makes the light-emitting portion 122 close to the third adhesive portion 134 and far away from the first adhesive portion 132. The third adhesive portion 134 can work with the opaque third adhesive to block light, avoiding local light leakage, thereby improving the light-emitting effect of the light-emitting component 12.

[0050] Please refer to this as well. Figures 1-3 In one embodiment, the first adhesive portion 132 and the second adhesive portion 133 form a stepped structure.

[0051] The vertical distance from the second adhesive portion 133 to the glass substrate 11 is greater than the vertical distance from the first adhesive portion 132 to the glass substrate 11. The first adhesive portion 132 and the second adhesive portion 133 form a stepped structure, which not only provides sufficient space for the accommodating cavity to place the light-emitting component 12, but also facilitates the first adhesive portion 132 to adhere tightly to the glass substrate 11 and the second adhesive portion 133 to adhere tightly to the light-emitting component 12, further avoiding local light leakage, further improving the light emission uniformity of the light-emitting component 12, and further improving the light emission effect of the light-emitting component 12.

[0052] Please refer to this as well. Figures 1-3 In one embodiment, the overlapping portion 131 has a photoblocking portion on the side facing the glass substrate 11, the photoblocking portion being used to absorb and / or reflect light from the light-emitting component 12.

[0053] A photoblocking component is disposed on the surface of the overlapping portion 131 facing the glass substrate 11. Optionally, the photoblocking component is detachably connected to the overlapping portion 131. Optionally, the photoblocking component and the overlapping portion 131 are integrally formed structural components.

[0054] The photoblocking element can be made of a light-absorbing / reflective material. Alternatively, the photoblocking element can be made of a wear-resistant coating, flocking, reflective tape, pure black coating, or tape.

[0055] In summary, by providing a light-blocking sub-part at the overlap portion 131, this embodiment further absorbs and / or reflects the light from the self-luminous component 12, thereby further preventing light leakage from the cover plate 13, further preventing local light leakage, further improving the light emission uniformity of the light-emitting component 12, and further improving the light emission effect of the light-emitting component 12.

[0056] Furthermore, the light-blocking sub-part and the overlapping part 131 work together to absorb and / or reflect light, and to tightly press and bond with the glass, thereby achieving the effect of preventing light leakage.

[0057] Please refer to this as well. Figures 1-3 In one embodiment, the glass substrate 11 includes a shielding layer, and the first adhesive portion 132 is located at the orthographic projection of the glass substrate 11 and is staggered with the shielding layer.

[0058] The masking layer can form a masked area, also commonly referred to as a black border area. Optionally, the masking layer is disposed in the peripheral area of ​​the glass substrate 11. Optionally, the material of the masking layer is selected from at least one of dark ink and opaque polymer film. The masking layer can serve as a display background for the displayed image, better blocking ambient light and avoiding unnecessary interference with the view; it can also improve the contrast between the displayed image and the display background and achieve a higher color gamut, making the image display clearer; it can also mask interior trim parts, etc., to improve visual aesthetics.

[0059] The first adhesive portion 132 is positioned so that its orthogonal projection onto the glass substrate 11 avoids the shielding layer. This can also be understood as the area where the first adhesive portion 132 is bonded to the glass substrate 11 having no shielding layer. By defining the positional relationship between the first adhesive portion 132 and the shielding layer, this embodiment ensures the brightness of the light-emitting component 12 and prevents reflections from the glass substrate 11 that could cause bright lines on the shielding layer, thereby further improving the light-emitting effect of the light-emitting component 12.

[0060] This application also provides a vehicle, the vehicle including a body and a light-emitting glass assembly as described above, wherein the glass substrate of the light-emitting glass assembly is disposed at an opening in the body.

[0061] The glass substrate can be a windshield, side window, sunroof, corner window, or rear windshield, etc.

[0062] In summary, this embodiment employs the light-emitting glass assembly provided in this application. In the light-emitting glass assembly, by providing an overlapping portion at the edge of the cover plate and cooperating with a first adhesive portion, the first adhesive portion can fix the cover plate to the glass substrate and block at least part of the light from the self-emitting component. The overlapping portion can abut against the sealed glass substrate, further blocking the light from the self-emitting component, thereby preventing light leakage from the cover plate, avoiding local light leakage, improving the light emission uniformity of the light-emitting component, and improving the light emission effect of the light-emitting component.
