GLASS ASSEMBLY AND WINDOW ASSEMBLYFIELD
[0001] The present disclosure relates to the technical field of glass, in particular to a glass assembly with lighting function and a window assembly using the glass assembly.BACKGROUND
[0002] With the rapid development of automobile industry and the increasing requirement of consumers for vehicle functions, lighting glass with lighting effect has been widely valued by vehicle manufacturers and favored by the consumers. Generally, the lighting glass with lighting effect applies lighting enamel or ink on a surface of a glass plate based on pattern design, and incident light emitted by a light source arranged on the edge or the surface of the glass plate or a light source integrated in the glass plate is transmitted through a pattern area by scattering or diffusion, so as to realize different effects of lighting.
[0003] For laminated glass, in a lighting mode as shown in Fig. 1A, a glass assembly includes a first glass body 11, a second glass body 12 and an intermediate layer 13 laminated therebetween to attach the first glass body and the second glass body. A light source 20 is installed via a mounting bracket 31 and arranged at an edge of the first glass body 11, so that incident light emitted by the light source 20 can be injected into the first glass body 11 and emitted therefrom to realize lighting, as shown by arrows. In this way of placing the light source on the edge of the glass, the light source 20 is arranged perpendicular to the surface of the first glass body 11. That is, a surface of the light source perpendicular to a central light ray of the incident light is arranged perpendicular to the surface of the first glass body 11, and the central light ray of the incident light is parallel to the surface of the first glass body 11. Hence, the total reflection of the light in the glass assembly cannot be realized, and the light utilization rate cannot be guaranteed. Fig. 1B illustrates another lighting mode, in which the light source 20 is installed via a mounting bracket 32 and placed on the surface of the first glass body 11, and the incident light emitted by the light source 20 is guided into the glass assembly through a light guiding component (not shown by omission) . In another lighting mode shown in Fig. 1C, the light source 20 is installed via a mounting bracket 33 and placed on the surface of the first glass body 11. This mode includes a light guiding component 34 for guiding the incident light emitted by the light source into the glass assembly. The ways for placing the light source in Fig. 1B and Fig. 1C are obviously not suitable for installation occasions that require thickness or height dimensions. Accordingly, the glass assembly is larger in overall size and heavier than conventional products, which goes against the trend of compactness and lightweight followed by the development of vehicles, and requires higher design requirements for the light guiding component, complex structures and increased costs.SUMMARY

[0036] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed merely exemplify the specific ways of implementing and using the present disclosure, and do not limit the scope of the disclosure. When describing the structural positions of various components, such as the directions of upper, lower, top, bottom, etc., the description is not absolute, but relative. When the various components are arranged as shown in the figures, these directional expressions are appropriate, but when the positions of the various components in the figures would be changed, these directional expressions would also be changed accordingly.
[0037] In this context, the expression "comprising" or similar expressions "having" and so on which are synonymous are open, and do not exclude additional unlisted elements, steps or ingredients.
[0038] In this context, the terms "first" , "second" and so on are not used to limit the sequence and the number of components unless otherwise stated.
[0039] In this context, unless otherwise specified, the terms such as "install" , "attach" should be understood broadly. For example, it can be fixed connection, detachable connection or integrated; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meanings of the above terms in this context can be understood according to specific situations.
[0040] In the various described embodiments, the thickness of the glass is the thickness commonly used in the art, and the thickness of each laminated structure on the glass is suitable for the conventional range and is not limited as shown in the figures. In addition, although it is shown as plane glass in the figures, the glass of the present disclosure may also be curved glass. In various embodiments, it is described as an independent glass body or glass plate, however, in some cases, the surface of the glass body can also use special coating to improve thermal insulation and / or comfort.
[0041] In this context, "surface" of the glass body is bounded by a surface where the length and width of the glass body are located, and "edge" is bounded by a surface where the length or width and thickness or height of the glass body are located. "Section" of the glass assembly is taken along the thickness or height direction of the glass assembly.
[0042] Hereinafter, a glass assembly applied to a vehicle window glass will be described, but it does not exclude that the glass assembly can be applied to the building field such as door, window, curtain wall, and other vehicle environments such as airplane glass or ship glass. When the glass assembly is described as the vehicle window glass of a vehicle, "outside" and "inside" refer to the directions relative to vehicle body, "outside" refers to the direction away from the vehicle body and "inside" refers to the direction facing the vehicle body. It should be understood that the vehicle window glass according to the embodiment of the present disclosure includes, but is not limited to, front windshield, rear windshield, skylight glass, vehicle door glass or corner window glass, which can provide different lighting effects based on different requirements.
[0043] According to the concept of the present disclosure, a lighting unit is designed to change the arrangement mode of the light source and realize the specific transmission or distribution of the light, which can improve the light utilization rate, reduce the light loss, enhance the lighting effect, and optimize the space size of the lighting unit at the same time, so that the glass assembly can be applied to various occasions where there is a requirement for assembly space with improved lighting effect if necessary.
[0044] Fig. 2 illustrates a glass assembly according to an embodiment of the present disclosure, which includes a glass body 110 and a lighting unit arranged at an edge of the glass body 110. According to the present disclosure, the lighting unit includes a light source 200 and a mounting bracket 310 for mounting the light source 200. The light source 200 is, for example, a point or linear light source, such as monochromatic or trichromatic light emitting diode (LED) beads or LED light emitting strips, and one or more LED beads can be arranged according to different requirements. In addition, combined with the design and control of the light source, such as lighting state and / or color and / or light intensity and / or lighting time of one or more LEDs, it can also be lighted separately or simultaneously to achieve dynamic / static lighting effects, such as running water, flashing, breathing, sense of depth, etc., which can further enrich the lighting effect of the glass assembly and meet the requirements of some specific scene atmospheres. The mounting bracket 310 serves as a housing for accommodating the light source 200 and can provide support and protection for the light source.
[0045] According to different requirements, the mounting bracket and the light source can be attached to each other or formed integrally with each other. According to the present disclosure, the light source of the lighting unit is configured to be obliquely biased toward the glass body. In this context, "obliquely biased" means that a surface of the light source perpendicular to a central light ray of incident light has an oblique angle with respect to a surface of the glass body, and is not parallel or perpendicular to the surface of the glass body, preferably inclined at least 43 degrees, so that at least the central light ray of the incident light enters the glass body at an angle with respect to the surface of the glass body and is totally reflected. Preferably, the angle of the central light ray of the incident light with respect to the surface of the glass body is at most 47 degrees. In this way, at least the incident light along the optical axis of the light source can be totally reflected in the glass body after entering the glass body, so that the light can be scattered or diffused out of the glass body when reaching or contacting, for example, a pattern area arranged in the glass body or on the surface of the glass body, and thus the pattern can be observed and visible and a lighting effect can be provided. Moreover, at least the central light ray of the incident light entering the glass body at an angle with respect to the surface of the glass body is helpful to meet that the incident light enters the glass body at a suitable angle range and is totally reflected well in the glass body, thus avoiding the existence of light attenuation and improving the light utilization rate. In addition, due to the oblique bias of the light source, the required placement space of the light source along the height direction on the section of the glass assembly can be reduced, and the space utilization rate is improved. Depending on the adopted glass body, the oblique bias of the light source can reduce the height of the glass assembly on the section, such as by nearly half the height of the glass body, thus facilitating the application of the glass assembly with the lighting function disclosed in the present disclosure to various occasions with installation size requirements.
[0046] Referring to Fig. 2 again, corresponding to the light source 200, the mounting bracket 310 has a mounting surface 311 for attaching with the light source 200. Optionally, the mounting surface 311 is inclined with respect to the surface of the glass body 110 at an inclination angle which is approximately the same as that of the light source 200. In this context, "approximately the same" covers a structural design with exactly the same inclination angle with respect to the inclination angle of the light source within the range of process error and the structural designs within a certain range of angular deviation with respect to the inclination angle of the light source. Alternatively, the mounting bracket can be attached to the glass body by adhesive or injection molding, which can reduce the production cost and use cost and facilitate the improvement of production efficiency, or the mounting bracket can also be attached to the glass body by mechanical fixing such as clamping piece. Depending on different requirements, the mounting bracket 310 may be attached to the edge of the glass body 110 and / or to the surface of the glass body 110. For example, as exemplified in Fig. 2, the mounting bracket 310 may be attached to the edge of the glass body 110 while having an adhesive portion 312 extending onto the surface of the glass body 110.
[0047] In some embodiments, the edge of the glass body 110 is provided with a light condensing surface. In the embodiment shown in Fig. 2, a light condensing surface 120 on the edge of the glass body 110 is configured as an arc protruding toward the light source 200, and unlike the edge form of the conventional glass body, a connecting line (shown as dotted line in Fig. 2) between both ends of the arc of the light condensing surface 120 is inclined with respect to the surface of the glass body 110 at an inclination angle α which is approximately the same as that of the light source 200, that is, preferably at least 43 degrees. As mentioned above, "approximately the same" covers the structural design with exactly the same inclination angle with respect to the inclination angle of the light source within the range of process error and the structural designs within a certain range of angular deviation with respect to the inclination angle of the light source. This arrangement is beneficial to gather the incident light emitted by the light source 200 before entering into the glass body, so that the incident light can be fully utilized, and the intensity of light entering the glass body for transmission and total reflection can be enhanced. In addition, arranging the light condensing surface at the edge of the glass body saves the additional installation space of condensing component, ensures that the enhanced lighting effect can still be obtained under the condition that the light source is obliquely biased, and is beneficial to optimizing the height dimension of the lighting unit on the section of the glass assembly.
[0048] In some embodiments, a light guiding component with a light guiding surface can be arranged on the edge of the glass body, and the light guiding surface is configured as an arc protruding toward the light source, and a connecting line between both ends of the arc is inclined with respect to the surface of the glass body at an inclination angle which is approximately the same as that of the light source. In some embodiments, the light guiding component is attached to an attachment surface arranged at the edge of the glass body, and the attachment surface is inclined with respect to the surface of the glass body at an inclination angle which is approximately the same as that of the light source, or the attachment surface is perpendicular to the surface of the glass body. Such an embodiment will be described in detail below with reference to Figs. 4 and 5. In this way, the light guiding component with a specific light guiding surface can be well attached to the edge of the glass body, and the installation space will not be additionally increased, which also ensures that the enhanced lighting effect can be obtained under the condition that the light source is obliquely biased. In the following descriptions of various embodiments, the advantages brought by this design will be more clear.
[0049] Fig. 3A illustrates a glass assembly according to another embodiment of the present disclosure. The glass assembly includes a first glass body 111 and a second glass body 112, which are attached to each other through an intermediate layer 113. The intermediate layer 113 is, for example, an adhesive layer suitable for laminated glass such as polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) . Depending on different application environments, the first glass body 111 may face the outside of the vehicle and may be called external glass, and the second glass body 112 may face the inside of the vehicle and may be called internal glass. The lighting unit may be arranged at the edge of the first glass body 111 and / or the edge of the second glass body 112 to achieve the lighting effect on the inside and / or outside of the vehicle.
[0050] In the illustrated embodiment, the lighting unit includes the light source 200 and the mounting bracket 310 for mounting the light source 200. The light source is configured to be obliquely biased toward the first glass body and / or the second glass body. Similarly, the oblique bias here means that the surface of the light source perpendicular to the central light ray of the incident light has an oblique angle compared with the surface of the first glass body and / or the surface of the second glass body, and is not parallel or perpendicular to the surface of the first glass body and / or the surface of the second glass body, preferably inclined at least 43 degrees, so that at least the central light ray of the incident light enters the first glass body and / or the second glass body at an angle with respect to the surface of the first glass body and / or the surface of the second glass body and is totally reflected. Preferably, the angle of the central light ray of the incident light with respect to the surface of the first glass body and / or the surface of the second glass body is at most 47 degrees. For example, in Fig. 3A, the incident light is totally reflected in the first glass body 111, and those skilled in the art can understand that the incident light can also be totally reflected in the first glass body 111, the intermediate layer 113 and the second glass body 112 through corresponding design, which is not repeated here. In addition, the first glass body 111 and the second glass body 112 formed as "large and small pieces" shown in Fig. 3A is only an example, and the present disclosure is not limited to such large and small pieces’ mode. Advantageously, the surface of the light source 200 perpendicular to the central light ray of the incident light is configured to be inclined at least 43 degrees with respect to the surface of the first glass body 111 and / or the surface of the second glass body 112, thereby ensuring good total reflection of the incident light in the glass body.
[0051] In some embodiments, the mounting bracket may be attached to the surface of the first glass body or the surface of the second glass body facing the intermediate layer, and / or attached to the edge of the first glass body and / or the edge of the second glass body, and / or attached to the surface of the first glass body and / or the surface of the second glass body away from the intermediate layer. By adopting different arrangements, the height dimension of the lighting unit on the section of the glass assembly can be optimized, for example, it can be no greater than or be approximately equal to the whole thickness of the glass assembly. For example, when the mounting bracket is attached to the surface of the first glass body or the surface of the second glass body facing the intermediate layer, the mounting bracket can be configured such that the height dimension on the section of the glass assembly is not greater than or is approximately equal to the thickness of the glass assembly. When the mounting bracket is attached to the edge of the first glass body and / or the edge of the second glass body, the mounting bracket can be configured such that the height dimension on the section of the glass assembly is equal to the thickness of the glass assembly. When the mounting bracket is attached to the surface of the first glass body and / or the surface of the second glass body away from the intermediate layer, the mounting bracket can be configured such that the height dimension on the section of the glass assembly is approximately equal to the thickness of the glass assembly.
[0052] Figs. 3A and 3B illustrate an embodiment in which the light source 200 of the lighting unit is obliquely biased toward the first glass body 111, and at least the central light ray of the incident light enters the first glass body 111 at an angle with respect to the surface of the first glass body 111 and is totally reflected. Accordingly, the mounting bracket 310 can be attached to the surface of the second glass body 112 facing the intermediate layer 113, and has the mounting surface 311 for attaching with the light source 200. Alternatively, the mounting surface 311 is inclined with respect to the surface of the first glass body 111 at an inclination angle which is approximately the same as that of the light source 200. Depending on different requirements, the mounting bracket 310 may be attached to the surface of the second glass body 112 facing the intermediate layer 113, and / or attached to the edge of the first glass body 111 and / or the edge of the second glass body 112. For example, when the mounting bracket 310 is arranged to be attached to the surface of the second glass body 112 facing the intermediate layer 113, the mounting bracket 310 may be attached to the edge of the first glass body 111 and supported by the surface of the second glass body 112 facing the intermediate layer 113. In this way, compared with the prior art shown in Fig. 1A, the glass assembly disclosed by the present disclosure not only meets that the incident light (especially the central light ray of the incident light) enters the glass body in a proper angle range and is well totally reflected in the glass body, thus avoiding the existence of light attenuation and improving the light utilization rate, but also can reduce the placement space required by the light source and its mounting bracket along the height direction on the section of the glass assembly, thus improving the space utilization rate, so that the glass assembly with lighting function can be applied to various occasions with installation size requirements. It should be understood that when the light source 200 is configured to be obliquely biased toward the second glass body, the glass assembly can also achieve the lighting effect (for example, oriented toward the inside of the vehicle) , which will not be described in detail here.
[0053] Alternatively, or additionally, in order to achieve reliable fixing of the mounting bracket, the mounting bracket 310 can also be attached to the edge of the second glass body 112 in the manner shown in Figs. 3A and 3B, and in some embodiments, the mounting bracket 310 can also be attached to the surface of the second glass body 112 away from the intermediate layer 113. For example, when the mounting bracket 310 is attached to the edge of the second glass body 112, the mounting bracket 310 may be simultaneously attached to the edges of the first glass body 111 and the second glass body 112 of the glass assembly, and be approximately flush with the surface of the glass assembly. The way in which the mounting bracket 310 is attached to the surface of the second glass body 112 away from the intermediate layer 113 can be shown with reference to Fig. 3B, for example. The mounting bracket 310 is attached to the surface of the second glass body 112 facing the intermediate layer 113, and simultaneously attached to the edges of the first glass body 111 and the second glass body 112, and has an adhesive portion 312 that can extend onto the surface of the second glass body 112 away from the intermediate layer 113. In this way, the mounting bracket 310 is supported by the surface of the second glass body 112 facing the intermediate layer 113, the edges of the first glass body 111 and the second glass body 112, and the surface of the second glass body 112 away from the intermediate layer 113, thereby ensuring sufficient structural strength. In this way, the lighting unit improves the light utilization rate and the space utilization rate at the same time, and ensures the reliable fixation with respect to the glass body.
[0054] In some embodiments, the edge of the first glass body 111 and / or the edge of the second glass body 112 is provided with a light condensing surface. In combination with the embodiment shown in Figs. 3A and 3B, a light condensing surface 114 is formed at the edge of the first glass body 111, which is in the shape of an arc protruding toward the light source 200. In addition, a connecting line (shown as dotted line in Fig. 3B) between both ends of the arc of the light condensing surface 114 is inclined with respect to the surface of the first glass body 111 at an inclination angle α which is approximately the same as that of the light source 200, that is, preferably at least 43 degrees.
[0055] The light condensing surface 120 shown in Fig. 2 and the light condensing surface 114 shown in Figs. 3A and 3B can be obtained by precisely polishing the edge of the glass body into a convex lens form. Similarly, in some embodiments, the lighting unit may include a light guiding component arranged at the edge of the first glass body 111 and / or the edge of the second glass body 112, and the light guiding component is provided with a light guiding surface. The light guiding surface is configured as an arc protruding toward the light source, and a connecting line between both ends of the arc is inclined with respect to the surface of the first glass body and / or the surface of the second glass body at an inclination angle which is approximately the same as that of the light source 200, so that it can play a role in guiding and condensing the incident light. Compared with the process of precisely polishing the edge of the glass body to form a light condensing surface, the light guiding component with the expected shape is easier to be manufactured.
[0056] In an embodiment shown in Fig. 4, the edge of the first glass body 111 is provided with an attachment surface 115. The attachment surface 115 is, for example, in a substantially planar form and is configured to have an inclination angle α with respect to the surface of the first glass body 111, that is, approximately the same as the inclination angle of the light source 200. A light guiding component 410 is configured to be attached to the attachment surface 115 and has a light guiding surface 411 configured as an arc protruding toward the light source 200. In an embodiment shown in Fig. 5, the edge of the first glass body 111 is provided with an attachment surface 116, and the attachment surface 116 is also configured to be, for example, substantially planar, but unlike the embodiment shown in Fig. 4, the attachment surface 116 in this embodiment is perpendicular to the surface of the first glass body 111. A light guiding component 420 is configured to be attached to the attachment surface 116, and has a light guiding surface 421 configured as an arc protruding toward the light source 200. At the same time, a connecting line (shown as dotted line in Fig. 5) between both ends of the arc of the light guiding surface 421 is inclined with respect to the surface of the first glass body 111 at an inclination angle α which is approximately the same as that of the light source 200. It should be understood that it is easy to form an attachment surface in a substantially planar form and inclined to the surface of the glass body or perpendicular to the surface of the glass body at the edge of the glass body, and it is also convenient to attach with the light guiding component. In any case, the light guiding component 410 or 420 can be attached to the attachment surface 115 or 116 of the edge of the first glass body 111 by, for example, an adhesive.
[0057] Advantageously, in the above-mentioned embodiments, the materials of the light guiding component and the adhesive are selected to have a refractive index close to that of the glass. For example, when the refractive index of the glass body is about 1.51, the material with the refractive index of about 1.51, for example, about 1.49 -1.52, can be used, so that the incident direction will not change basically when the incident light is transmitted to the glass body through the light guiding component and the adhesive. Alternatively, the material of the light guiding component includes but is not limited to glass, polymethyl methacrylate (PMMA) , polycarbonate (PC) , polyethylene terephthalate (PET) , polyolefin (PO) , polyvinyl chloride (PVC) , and other suitable composite plastics. The adhesive includes, but is not limited to, any one of light curing adhesive (UV adhesive) , thermosetting adhesive, unsaturated polyester adhesive, epoxy resin adhesive, polyurethane adhesive, silicone rubber and acrylic acid.
[0058] In some embodiments as shown in Fig. 6A, the lighting unit may include a first light source 200a arranged at the edge of the first glass body 111 and obliquely biased, and a second light source 200b arranged at the edge of the second glass body 112 and obliquely biased. The first light source 200a and the second light source 200b may be arranged at the edges of different sides of the glass assembly, respectively. For example, the inclination angle of the first light source 200a with respect to the surface of the first glass body 111 may be consistent with the inclination angle of the second light source 200b with respect to the surface of the second glass body 112. Accordingly, in an embodiment shown in Fig. 6A, the mounting bracket includes a first mounting bracket 310a corresponding to the first glass body 111 and a second mounting bracket 310b corresponding to the second glass body 112, and the first mounting bracket 310a has a first mounting surface 311a for attaching with the first light source 200a, and the second mounting bracket 310b has a second mounting surface 311b for attaching with the second light source 200b. Optionally, the first mounting surface 311a is inclined with respect to the surface of the first glass body 111 at an inclination angle which is approximately the same as that of the first light source 200a, while the second mounting surface 311b is inclined with respect to the surface of the second glass body 112 at an inclination angle which is approximately the same as that of the second light source 200b. In the way that the first light source and the second light source are arranged at the edges of different sides of the glass assembly, the mounting brackets 310a, 310b can be respectively arranged at the edges of the first glass body 111 and the second glass body 112 as illustrated in Fig. 6A, and can be attached to the surfaces of the first glass body 111 and the second glass body 112 facing the intermediate layer 113 in the manner described above in connection with Fig. 3A, or additionally be attached to the edges of the first glass body 111 and the second glass body 112, or additionally be attached to the edges of the first glass body 111 and the second glass body 112 and have adhesive portions 312a, 312b that can extend onto the surfaces of the first glass body 111 and the second glass body 112 away from the intermediate layer 113.
[0059] Fig. 6B exemplarily illustrates that the first light source 200a and the second light source 200b are arranged at the edges of the same side of the glass assembly. In some alternative embodiments, the first light source 200a and the second light source 200b may be symmetrically arranged, that is, the inclination angle of the first light source 200a with respect to the surface of the first glass body 111 is consistent with the inclination angle of the second light source 200b with respect to the surface of the second glass body 112. In the illustrated embodiment, a mounting bracket 320 is configured to have a first mounting surface 321 for attaching with the first light source 200a and a second mounting surface 322 for attaching with the second light source 200b. Optionally, the first mounting surface 321 is inclined with respect to the surface of the first glass body 111 at an inclination angle which is approximately the same as that of the first light source 200a, and the second mounting surface 322 is inclined with respect to the surface of the second glass body 112 at an inclination angle which is the same as that of the second light source 200b. In such a way that the first light source and the second light source are arranged at the edges of the same side of the glass assembly, the mounting bracket 320 can be attached to the edges of the first glass body 111 and the second glass body 112, and have adhesive portions 323, 324 that can extend onto the surfaces of the first glass body 111 and the second glass body 112 away from the intermediate layer 113.
[0060] The way of providing light sources to the first glass body and the second glass body respectively can facilitate achieving the effect of simultaneously illuminating the glass assembly toward the exterior and the interior of the vehicle. In some embodiments, the first glass body 111 may be configured with the light condensing surface 114 similar to the embodiment shown in Fig. 3A, and the second glass body 112 may be configured to be provided with the light guiding component 410 similar to the embodiment shown in Fig. 4. It should be understood that depending on different requirements, in the case that the edges of the first glass body and the second glass body are both provided with corresponding light sources, the edges of the first glass body and the second glass body can be constructed in the same form or in different forms, as long as the incident light emitted by the light sources is condensed into the glass body and the total reflection of the light in the glass body is realized.
[0061] In each of the above embodiments, by arranging the light source at the edge of the glass body and obliquely biasing the light source toward the glass body, the glass assembly of the present disclosure provides enhanced lighting effect on the premise of fully utilizing the light of the light source, and provides a relatively reduced installation volume of the light source and its mounting bracket, and the height dimension of the optimally designed lighting unit can be kept substantially consistent with that of the conventional single-layer glass body or laminated glass with beautiful edges. In addition, compared with the way of integrating the light source into the glass body, the glass assembly disclosed by the present disclosure does not need to carry out processes such as drilling holes on the glass body, thus reducing the light loss while also ensuring the structural strength of the glass assembly, and the lighting unit is simple in structure and easy to be assembled, thereby improving the user experience comfort and the product market competitiveness.

However, it can be understood that those skilled in the art can make various changes and improvements to the above disclosed concept under the creative idea of the present disclosure, all of which fall within the protection scope of the present disclosure.
