[0047] As described in the background, in the related art, the light emitting device is usually arranged in the transparent area of the glass assembly, and the appearance of the glass assembly presents a granular feeling due to the visibility of the light emitting device, resulting in poor aesthetic appearance of the glass assembly.

[0048] In view of the above problems, the embodiments of the present application provide a glass assembly and a vehicle, by making the orthographic projection of the light emitting element on the first glass layer fall within the orthographic projection range of the shielding layer on the first glass layer, the shielding layer can shield the light emitting element, and the light emitting element can be hidden. The granular feeling phenomenon of the light emitting element visible to the naked eye on the appearance of the glass assembly is solved, and the appearance aesthetic appearance of the glass assembly and the vehicle is improved.

[0049] In a first aspect, with reference to Figures 1-4AAs shown, the embodiment of the present application provides a glass assembly 10 which can be applied on a vehicle, for example. The glass assembly 10 comprises a first glass layer 11, a second glass layer 12, a shielding layer 13 and a light emitting element 14.

[0050] The second glass layer 12 is arranged on one side of the first glass layer 11. The shielding layer 13 is arranged between the first glass layer 11 and the second glass layer 12. The light emitting element 14 is arranged between the first glass layer 11 and the second glass layer 12 and on the side of the shielding layer 13 facing the second glass layer 12. The orthographic projection of the light emitting element 14 on the first glass layer 11 falls within the orthographic projection range of the shielding layer 13 on the first glass layer 11.

[0051] Here, the orthographic projection of the light emitting element 14 on the first glass layer 11 refers to the projection of the light emitting element 14 on the first glass layer 11 along the thickness direction (e.g. the vertical direction in FIG. 1) of the first glass layer 11. Figure 3 The orthographic projection of the shielding layer 13 on the first glass layer 11 refers to the projection of the shielding layer 13 on the first glass layer 11 along the thickness direction (e.g. the vertical direction in FIG. 1) of the first glass layer 11. Figure 3

[0052] In the embodiment of the present application, one of the first glass layer 11 and the second glass layer 12 can be an outside glass layer, and the other can be an inside glass layer. The light emitting element 14 can be a device which emits light to the inside of the vehicle through the inside glass layer, or a device which emits light to the outside of the vehicle through the outside glass layer.

[0053] In one example, the first glass layer 11 is an outside glass layer, the second glass layer 12 is an inside glass layer, and the light emitting element 14 emits light to the inside of the vehicle through the inside glass layer.

[0054] In another example, the first glass layer 11 is an inside glass layer, the second glass layer 12 is an outside glass layer, and the light emitting element 14 emits light to the outside of the vehicle through the outside glass layer.

[0055] It should be noted that the shielding layer 13 is an opaque layer, which can be provided in a strip shape along the peripheral portion of the first glass layer 11, for example. The shielding layer 13 can also be in the shape of a slit, a lattice or a pattern, etc. The shielding layer 13 can be provided in any region on the first glass layer 11, and the embodiment of the present application does not limit the position of the shielding layer 13.

[0056] ​The shielding layer 13 can be a non-transparent (e.g., black) colored ceramic layer. For example, the shielding layer 13 can be a colored interlayer film or colored film having light shielding properties, a combination of a colored interlayer film and a colored ceramic layer. The colored film can be integrated with an infrared reflective film or the like. By providing the non-transparent shielding layer 13 on the first glass layer 11, degradation of the glass assembly 10 can be suppressed.

[0057] The shielding layer 13 can be formed by screen printing a ceramic color paste containing a fusible glass frit with black pigment on the first glass layer 11 and firing, but is not limited thereto. The shielding layer 13 can also be formed by screen printing an organic ink containing white, black or dark pigment on the first glass layer 11 and drying.

[0058] The glass assembly 10 provided by the embodiments of the present application can cause the shielding layer 13 to shield the light emitting element 14 by causing the orthographic projection of the light emitting element 14 on the first glass layer 11 to fall within the orthographic projection range of the shielding layer 13 on the first glass layer 11, so that the light emitting element 14 is hidden. This solves the problem of the grainy feeling of the light emitting element 14 being visible to the naked eye on the appearance of the glass assembly 10, and improves the appearance of the glass assembly 10.

[0059] It should be noted that the conventional glass assembly 10 is usually provided with a shielding layer 13, so the light emitting element 14 can be arranged in the area where the original shielding layer 13 is located, so that the shielding layer 13 shields the light emitting element 14. In addition, the shielding layer 13 can be arranged in the area where the light emitting element 14 is needed to be arranged, so that the light emitting element 14 is hidden.

[0060] In one embodiment, the light emitting element 14 is connected to the shielding layer 13, i.e., the light emitting element 14 is directly connected to the shielding layer 13. In this way, the light emitting element 14 is equivalent to being directly made on the shielding layer 13, which can reduce the structural complexity of the glass assembly 10. For example, the light emitting element 14 and the shielding layer 13 can be a split structure, and when the light emitting element 14 and the shielding layer 13 are a split structure, they can be fixedly connected, detachably connected, or the like. In addition, the light emitting element 14 and the shielding layer 13 can also be an integrated structure.

[0061] In one embodiment, the shielding layer 13 includes a conductive material, and the connecting electrode of the light emitting element 14 is electrically connected to the shielding layer 13. In this way, the shielding layer 13 can have a conductive function, so that the shielding layer 13 can transmit an electrical signal to the light emitting element 14, which is advantageous to reduce the number of wires and thus reduce the structural complexity of the glass assembly 10.

[0062] In one of the embodiments, the glass assembly 10 further comprises a bonding structure 15 arranged between the first glass layer 11 and the second glass layer 12 to connect the first glass layer 11 and the second glass layer 12. The shielding layer 13 is arranged between the first glass layer 11 and the bonding structure 15. In this way, the structural stability of the glass assembly 10 is improved.

[0063] In one of the embodiments, the bonding structure 15 can be made of polyvinyl butyral, ethylene-vinyl acetate, polyurethane or polyvinyl chloride.

[0064] In one of the embodiments, referring to FIG. 1, the bonding structure 15 has a receiving cavity 15a, and the light emitting element 14 is arranged in the receiving cavity 15a. In this way, a space for assembling the light emitting element 14 is provided in the bonding structure 15, and the light emitting element 14 is easily assembled. Figure 4A

[0065] In one of the embodiments, the bonding structure 15 comprises a first bonding layer 151, a second bonding layer 152 and a third bonding layer 153. The first bonding layer 151 is arranged on the side of the first glass layer 11 facing the second glass layer 12 and connected to the first glass layer 11. The second bonding layer 152 is arranged on the side of the first bonding layer 151 facing the second glass layer 12 and connected to the second glass layer 12. The third bonding layer 153 is arranged between the first bonding layer 151 and the second bonding layer 152. The first bonding layer 151, the second bonding layer 152 and the third bonding layer 153 jointly define the receiving cavity 15a. In this way, the structure of the bonding structure 15 is relatively simple, and the manufacturing and assembly are facilitated.

[0066] Exemplarily, the first bonding layer 151, the second bonding layer 152 and the third bonding layer 153 can be made of polyvinyl butyral, ethylene-vinyl acetate, thermoplastic polyurethane elastomer, polyolefin elastomer, polyurethane or ionomer film, etc.

[0067] Polyvinyl butyral, abbreviated as PVB, is a solvent type resin synthesized by the acetal condensation reaction of polyvinyl alcohol (abbreviated as PVA) and butyraldehyde under the action of an acid catalyst. It has good moldability, and the formed coating film has high transparency, toughness, weather resistance and other superior properties. Moreover, its special chemical structure can have excellent adhesion to glass, metal, ceramic and the like.

[0068] Ethylene-vinyl acetate copolymer, abbreviated as EVA. The content of vinyl acetate (VA) is generally 5%-40%. Compared with polyethylene PE, EVA reduces the high crystallinity and improves the toughness, impact resistance, filler compatibility and heat sealing performance due to the introduction of vinyl acetate monomer in the molecular chain.

[0069] ​Thermoplastic polyurethane elastomer (TPU) is a kind of elastomer which can be plasticized by heating and dissolved by solvent. It has excellent comprehensive performance such as high strength, high toughness, wear resistance, oil resistance, good processing performance, and is widely used in national defense, medical treatment, food industry and other industries. Thermoplastic polyurethane elastomer has become one of the important thermoplastic elastomer materials due to its excellent performance and wide application. The molecule of thermoplastic polyurethane elastomer is basically linear, and there is no or little chemical crosslinking. There are many physical crosslinking of hydrogen bonds between linear polyurethane molecular chains, and hydrogen bonds play a strengthening role on the morphology, thereby giving many excellent properties such as high modulus, high strength, excellent wear resistance, chemical resistance, hydrolysis resistance, high and low temperature resistance and mold resistance.

[0070] Polyolefin elastomer (POE) is a kind of random copolymer of ethylene / higher alpha-olefin with higher comonomer content. Compared with polyolefin, POE not only has the advantages of the former, but also has more excellent chemical properties, rheological properties and aging resistance.

[0071] Polyurethane (PU) is a kind of high molecular compound. It was first synthesized by Otto Bayer in 1937. Polyurethane can be divided into two categories: polyester type and polyether type. They can be made into polyurethane plastics (mainly foam plastics), polyurethane fibers (known as spandex in China), polyurethane rubber and elastomer. Soft polyurethane is mainly a linear structure with thermoplasticity. It has better stability, chemical resistance, resilience and mechanical properties than PVC foamed materials, and has smaller compression deformation. It has good heat insulation, sound insulation, shock resistance and anti-toxicity performance.

[0072] Ionic polymer refers to a kind of polymer containing metal ions, with specific gravity of 0.94-0.960 and softening point of 35℃. It can be used continuously at 90℃ in air. The main chain of its molecular structure is the copolymer of ethylene and methacrylic acid, and metal ions are introduced on it, and ionic bond is used as intermolecular crosslinking. It has low crystallinity, good transparency, high elongation and elasticity, high tensile strength and impact strength.

[0073] In one specific embodiment, the third adhesive layer 153 can be disposed at the edges of the first adhesive layer 151 and the second adhesive layer 152.

[0074] In one possible embodiment, the third adhesive layer 153 and the first adhesive layer 151 are of an integrated structure, or the third adhesive layer 153 and the second adhesive layer 152 are of an integrated structure.

[0075] In one embodiment, the glass assembly 10 further comprises a transparent layer 16, which is arranged between the first glass layer 11 and the second glass layer 12, and is arranged in the accommodating cavity 15a, for example. The light emitting element 14 is arranged on the transparent layer 16. In this way, when manufacturing the glass assembly 10, the light emitting element 14 can be arranged on the transparent layer 16 first, and then the transparent layer 16 is arranged in the accommodating cavity 15a, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0076] It can be understood that the transparent layer 16 can be made of polymethyl methacrylate, acrylonitrile-styrene-diene copolymer, styrene, polyvinylidene fluoride, etc.

[0077] In one embodiment, the transparent layer 16 has a light transmittance greater than or equal to 50%. In a preferred embodiment, the transparent layer 16 has a light transmittance greater than 70%. In this way, the light transmittance of the glass assembly 10 can be improved.

[0078] In one embodiment, as shown in Figure 4A , the light emitting element 14 can be arranged on one side of the transparent layer 16.

[0079] In one embodiment, as shown in Figure 4B , the transparent layer 16 can have a hollow hole, and the light emitting element 14 is arranged in the hollow hole. In this way, the assembly stability of the transparent layer 16 and the light emitting element 14 can be improved.

[0080] It should be noted that the transparent layer 16 can be a transparent substrate or a transparent functional layer, such as a transparent sound insulation layer, a transparent heat insulation layer, a transparent light guide layer, a transparent display functional layer, etc.

[0081] In one embodiment, as shown in Figure 5 , the shielding layer 13 is arranged on the transparent layer 16, and the shielding layer 13 and the light emitting element 14 are arranged on two sides of the transparent layer 16. In this way, when manufacturing the glass assembly 10, the shielding layer 13 can be manufactured on the transparent layer 16 first, so that it is not necessary to print or mark the shielding layer 13 on the glass in advance. On the one hand, the process of manufacturing the shielding layer 13 on the glass can be omitted, and on the other hand, the light emitting element 14 and the shielding layer 13 are both manufactured on the transparent layer 16, so that the process of aligning the light emitting element 14 with the shielding layer 13 on the glass during the glass lamination process can be omitted, thereby reducing the difficulty of alignment and achieving better alignment of the light emitting element 14 and the shielding layer 13.

[0082] In one of the embodiments, the glass assembly 10 further comprises a flexible wire (not shown in the figure) which is electrically connected with the connecting electrode of the light emitting element 14. By arranging the flexible wire, the wire of the light emitting element 14 can be made bendable, and can adapt to the curved shape (or other irregular shape) of the glass assembly 10.

[0083] It can be understood that the light emitting element 14 can be made of electroluminescent material.

[0084] In one of the embodiments, the material of the light emitting element 14 comprises one or more of ZnS, Cu, YAG, Mn, and Al. In this way, on the one hand, the light emitting element 14 can have electroluminescent function, and on the other hand, the light emitting element 14 can be printed or printed on the shielding layer 13.

[0085] In one of the embodiments, the shielding layer 13 comprises a plurality of shielding portions 131 arranged at intervals, and the number of the light emitting elements 14 is also a plurality, and the plurality of light emitting elements 14 are arranged one by one corresponding to the plurality of shielding portions 131. That is, one light emitting element 14 corresponds to one shielding portion 131, and the one shielding portion 131 is used to shield the corresponding one light emitting element 14.

[0086] Further, the orthographic projection area of the light emitting element 14 on the first glass layer 11 is less than or equal to the orthographic projection area of the corresponding shielding portion 131 on the first glass layer 11. In this way, the shielding portion 131 can form better shielding for the light emitting element 14, and the appearance can be improved.

[0087] In one of the embodiments, the ratio of the orthographic projection area of the light emitting element 14 on the first glass layer 11 to the orthographic projection area of the corresponding shielding portion 131 on the first glass layer 11 is between 0.5-0.9. That is, the area of the light emitting element 14 accounts for 50%-90% of the area of the shielding portion 131.

[0088] If the ratio of the orthographic projection area of the light emitting element 14 to the orthographic projection area of the shielding portion 131 is greater than 0.9, the side where the shielding portion 131 is located is prone to have obvious light leakage phenomenon, and the surrounding of the shielding portion 131 is prone to have obvious light spot phenomenon. If the ratio of the orthographic projection area of the light emitting element 14 to the orthographic projection area of the shielding portion 131 is less than 0.5, the light emitting area of the light emitting element 14 is small, and the light emitting effect is not good.

[0089] The above arrangement can effectively shield the light emitted by the light emitting element 14 by the shielding portion 131, and prevent the side where the shielding portion 131 is located from having obvious light leakage phenomenon and the surrounding of the shielding portion 131 from having obvious light spot phenomenon.

[0090] It can be understood that the area of the light emitting element 14 can change with the change of the area of the shielding portion 131.

[0091] In a preferred embodiment, the ratio of the area of the orthographic projection of the light emitting element 14 on the shielding portion 131 to the area of the orthographic projection of the corresponding shielding portion 131 on the first glass layer 11 is between 0.7 and 0.8. In this way, on the one hand, the light emitted by the light emitting element 14 can be effectively shielded by the shielding portion 131, and on the other hand, the light emitting area and the luminous intensity of the light emitting element 14 can be increased.

[0092] In one of the embodiments, as shown in Figure 5 and Figure 6 , the light emitting element 14 is provided with a light emitting surface 141 on the side facing away from the shielding layer 13. The light emitted by the light emitting element 14 is emitted by the light emitting surface 141 and diffuses towards the circumference of the light emitting surface 141. Figure 6 In a top view of the light emitting element 14 when emitting light, it can be seen that the light emitted by the light emitting element 14 is centered on the light emitting surface 141 and diffuses towards the 360° circumference of the light emitting surface 141. The above arrangement is advantageous for improving the light emitting effect of the light emitting element 14.

[0093] In one of the embodiments, as shown in Figure 7 , a virtual plane perpendicular to the light emitting surface 141 and passing through the center of the light emitting element 14 is defined as a reference plane. In the reference plane, Figure 7 , the paper surface is the reference plane. In the reference plane, the light emitting element 14 has a light emitting angle a, which is greater than or equal to 60° and less than or equal to 120°.

[0094] Specifically, if the light emitting angle a is less than 60°, the light emitting width of the light emitting element 14 is small, resulting in poor light emitting effect at a large viewing angle. If the light emitting angle a is greater than 120°, the light emitted by the light emitting element 14 is more divergent, resulting in poor brightness. The above arrangement is advantageous for ensuring the light emitting effect and brightness of the light emitting element 14 at a large viewing angle.
