Description

Technical Field

[0001] The present disclosure relates to the field of glass technology, and in particular to a glass component with lighting function and a window assembly using the glass component. Background Art

[0002] With the rapid development of the automobile industry and the increasing demand of consumers for vehicle functions, lighting glass with lighting effects has been widely valued by vehicle manufacturers and favored by consumers. Generally, lighting glass with lighting effects uses lighting enamel or ink applied on the surface of the glass plate based on pattern design, and uses scattering or diffusion to transmit the incident light emitted by the light source set on the edge or surface of the glass plate or the light source integrated in the glass plate through the pattern area, thereby achieving different lighting effects.

[0003] For laminated glass, Figure 1A A lighting method is shown, in which a glass component includes a first glass body 11, a second glass body 12, and an intermediate layer 13 stacked between the first glass body 11 and attaching the second glass body 12, wherein a light source 20 mounted by a mounting frame 31 is arranged at the edge of the first glass body 11, so that the incident light emitted by the light source 20 enters the first glass body 11 and is emitted therefrom to achieve lighting, as shown by the arrow. In this method of placing the light source at the edge of the glass, the light source 20 is arranged perpendicular to the surface of the first glass body 11, that is, the surface of the light source perpendicular to the central ray of the incident light is arranged perpendicular to the surface of the first glass body 11, and the central ray of the incident light is parallel to the surface of the first glass body 11, so that the total reflection of the light in the glass component cannot be achieved, and the light utilization rate cannot be guaranteed. Figure 1B Another lighting method is shown, in which the light source 20 mounted by the mounting frame 32 is 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 component through a light guide (omitted and not shown). Figure 1C In another lighting method shown, the light source 20 mounted by the mounting frame 33 is placed on the surface of the first glass body 11. This method includes a light guide 34 for guiding the incident light emitted by the light source into the glass component. Figure 1B and Figure 1C The way of placing the light source is obviously not suitable for installation occasions that require thickness or height. Accordingly, the overall size of the glass component is larger and heavier than conventional products, which goes against the compact and lightweight trend followed by vehicle development, and has high requirements for the design of the light guide, complex structure and increased cost.

[0036] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present disclosure, and are not intended to limit the scope of the present disclosure. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0037] Herein, the expression "includes" or similar expressions "having" and the like are open-ended and do not exclude additional unrecited elements, steps or components.

[0038] Herein, the terms "first", "second", etc. are not used to limit the order of precedence and the number of components, unless otherwise specified.

[0039] In this document, unless otherwise specifically defined, the terms "installation", "attachment" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0040] In each embodiment described herein, the thickness of the glass is the thickness commonly used in the art, and the thickness of each laminated structure on the glass is applicable to the conventional range and is not limited to the one shown in the figure and the specific description below. In addition, although the figure shows a flat glass, the glass of the present disclosure may also be a curved glass. In each embodiment, it is described as an independent glass body or glass plate, but in some cases, a special coating may be used on the surface of the glass body to improve heat insulation and / or comfort.

[0041] Herein, the "surface" of a glass body is defined by the plane where the length and width of the glass body lie, and the "edge" is defined by the plane where the length or width and thickness or height of the glass body lie. A "cross section" of a glass component is taken along the thickness or height direction of the glass component.

[0042] Hereinafter, the glass assembly is described as being applied to vehicle window glass, but it does not exclude that the glass assembly can be applied to architectural fields such as doors, windows, curtain walls, and other transportation environments such as aircraft glass or ship glass. When the glass assembly describes the vehicle window glass used for a vehicle, "outside" and "inside" are directions relative to the 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 embodiments of the present disclosure includes but is not limited to the front windshield, rear windshield, sunroof glass, door glass or corner window glass, and can provide different lighting effects based on different needs.

[0043] According to the concept of the present disclosure, a lighting unit is designed to change the arrangement of light sources and realize specific propagation or distribution of light, thereby improving light utilization, reducing light loss, and enhancing lighting effects. At the same time, the spatial size of the lighting unit can be optimized so that the glass assembly can be used in various occasions that require assembly space with improved lighting effects when needed.

[0044] Figure 2 A glass assembly according to an embodiment of the present disclosure is shown, and the glass assembly includes a glass body 110 and a lighting unit arranged at the edge of the glass body 110. According to the present disclosure, the lighting unit includes a light source 200 and a mounting frame 310 for mounting the light source 200. The light source 200 is, for example, a point-shaped or linear light source, such as a single-color or three-color light-emitting diode (LED) lamp bead or an LED light strip, and one or more LED lamp beads can be arranged according to different needs. In addition, combined with the design and control of the light source, such as the lighting state and / or color and / or light intensity and / or lighting time of one or more LEDs, it can also be lit separately or simultaneously to achieve dynamic / static lighting effects, such as flowing water, flashing, breathing, depth, etc., which can further enrich the lighting effect of the glass assembly and meet the needs of certain specific scene atmospheres. The mounting frame 310, as a shell for accommodating the light source 200, can provide support and protection for the light source.

[0045] According to different needs, the mounting frame and the light source can be attached to each other or formed as one body. According to the present disclosure, the light source of the lighting unit is configured to be tilted and offset toward the glass body. In this article, "tilted offset" means that the surface of the light source perpendicular to the central ray of the incident light has an inclination angle relative to the surface of the glass body, is not parallel or perpendicular to the surface of the glass body, and is preferably tilted at least 43 degrees, so that at least the central ray of the incident light enters the glass body at an angle relative to the surface of the glass body and is fully reflected. Preferably, the angle of the central ray of the incident light relative 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 fully reflected in the glass body after entering the glass body, so that when the light reaches or contacts, for example, a pattern area set in the glass body or on the surface of the glass body, it can be scattered or diffused out of the glass body, so that the pattern is observed and visible and provides a lighting effect. In addition, at least the central ray of the incident light enters the glass body at an angle relative to the surface of the glass body, which helps to meet the requirements of the incident light entering the glass body in a suitable angle range and being well fully reflected in the glass body, avoiding the existence of light attenuation, and improving the utilization rate of light. In addition, due to the tilted offset of the light source, the placement space required for the light source in the height direction on the cross section of the glass component can be reduced, thereby improving space utilization. Depending on the glass body used, the tilted offset of the light source can reduce the height of the glass component on the cross section, for example, by nearly half of the height of the glass body, thereby facilitating the application of the glass component with lighting function disclosed in the present invention to various occasions with installation size requirements.

[0046] Recombination Figure 2 As shown, corresponding to the light source 200, the mounting bracket 310 has a mounting surface 311 for attaching to the light source 200. Optionally, the mounting surface 311 is inclined relative to the surface of the glass body 110 and the inclination angle is substantially the same as the inclination angle of the light source 200. Herein, "substantially the same" covers structural designs that are completely identical within the process error range in terms of the inclination angle relative to the light source, as well as structural designs within a certain angle deviation range. Alternatively, the mounting bracket can be attached to the glass body by means of adhesive or injection molding, which can reduce production costs and use costs and facilitate improved production efficiency. Alternatively, the mounting bracket can be attached to the glass body by means of mechanical fixing such as clamps. Depending on different needs, the mounting bracket 310 can be attached to the edge of the glass body 110 and / or to the surface of the glass body 110. For example Figure 2 As illustrated, the mounting bracket 310 may be attached to an edge of the glass body 110 and may have an adhesive portion 312 extending onto a surface of the glass body 110 .

[0047] In some embodiments, a light-gathering surface is disposed at an edge of the glass body 110 . Figure 2In the illustrated embodiment, the light-collecting surface 120 at the edge of the glass body 110 is configured as an arc convex toward the light source 200, and, unlike the edge form of a conventional glass body, the line connecting the two ends of the arc of the light-collecting surface 120 ( Figure 2 The light source 200 (shown by a dotted line in FIG. 1 ) is inclined relative to the surface of the glass body 110, and the inclination angle α is substantially the same as the inclination angle of the light source 200, that is, preferably, at least 43 degrees. As mentioned above, "substantially the same" covers structural designs that are completely identical in the process error range with respect to the inclination angle of the light source, as well as structural designs within a certain angle deviation range. With this arrangement, it is beneficial to gather the incident light emitted by the light source 200 before entering the glass body, so that the incident light can be fully utilized, thereby enabling the intensity of light that enters the glass body for transmission and total reflection to be enhanced. In addition, providing a focusing surface at the edge of the glass body eliminates the need for additional installation space for focusing elements, ensures that an enhanced lighting effect can still be obtained when the light source is tilted and offset, and helps optimize the height dimension of the lighting unit on the cross section of the glass assembly.

[0048] In some embodiments, a light-guiding element having a light-guiding surface may be arranged at the edge of the glass body, the light-guiding surface is configured as an arc convex toward the light source, the line connecting the two ends of the arc is inclined relative to the surface of the glass body, and the inclination angle is substantially the same as the inclination angle of the light source. In some embodiments, the light-guiding element is attached to an attachment surface provided at the edge of the glass body, the attachment surface is inclined relative to the surface of the glass body, and the inclination angle is substantially the same as the inclination angle of the light source, or the attachment surface is perpendicular to the surface of the glass body. Figure 4 and Figure 5 Such an embodiment is described in detail. In this way, the light guide element with a specific light guide surface can be well attached to the edge of the glass body without adding extra installation space, and also ensures that an enhanced lighting effect can be obtained when the light source is tilted and offset. The advantages brought by this design will become clearer in the description of the following embodiments.

[0049] Figure 3A A glass assembly according to another embodiment of the present disclosure is shown, the glass assembly includes a first glass body 111 and a second glass body 112, which are attached to each other via an intermediate layer 113, the intermediate layer 113 being, 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 referred to as the outer glass, the second glass body 112 may face the inside of the vehicle and may be referred to as the inner glass, and a lighting unit may be arranged at the edge of the first glass body 111 and / or the second glass body 112 to achieve a lighting effect on the inside and / or outside of the vehicle.

[0050] In the illustrated embodiment, the lighting unit includes a light source 200 and a mounting frame 310 for mounting the light source 200. The light source is configured to be tilted and offset toward the first glass body and / or the second glass body. Similarly, the tilt offset here means that the surface of the light source perpendicular to the central ray of the incident light has an inclination angle compared to the surface of the first glass body and / or the second glass body, and is not parallel or perpendicular to the surface of the first glass body and / or the second glass body. Preferably, it is tilted at least 43 degrees so that at least the central ray of the incident light enters the first glass body and / or the second glass body at an angle relative to the surface of the first glass body and / or the second glass body and is totally reflected. Preferably, the angle between the central ray of the incident light and the surface of the first glass body and / or the second glass body is at most 47 degrees. For example, Figure 3A The example in FIG. 1 shows that the incident light is totally reflected in the first glass body 111. It can be understood by those skilled in the art 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 will not be described in detail here. Figure 3A The "large and small pieces" of the first glass body 111 and the second glass body 112 shown are also only examples, and the present disclosure is not limited to such large and small pieces. Advantageously, the surface of the light source 200 perpendicular to the central ray of the incident light is configured to be inclined at least 43 degrees relative to the surface of the first glass body 111 and / or the second glass body 112, thereby ensuring that the incident light can be well totally reflected in the glass body.

[0051] In certain embodiments, the mounting bracket can be attached to the surface of the first glass body or the second glass body facing the intermediate layer, and / or attached to the edge of the first glass body and / or the second glass body, and / or attached to the surface of the first glass body and / or the second glass body facing away from the intermediate layer. By adopting different arrangements, the height dimension of the lighting unit on the cross section of the glass assembly can be optimized, for example, it can be not greater than or approximately equal to the thickness of the entire glass assembly. For example, when the mounting bracket is attached to the surface of the first glass body or the second glass body facing the intermediate layer, the mounting bracket can be configured so that the height dimension on the cross section of the glass assembly is not greater than or 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 second glass body, the mounting bracket can be configured so that the height dimension on the cross 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 second glass body facing away from the intermediate layer, the mounting bracket can be configured so that the height dimension on the cross section of the glass assembly is approximately equal to the thickness of the glass assembly.

[0052] Figure 3A and Figure 3BThe embodiment in which the light source 200 of the lighting unit is tilted and offset toward the first glass body 111 is shown, and at least the central ray of the incident light enters the first glass body 111 at an angle relative to the surface of the first glass body 111 and is totally reflected. Accordingly, the mounting frame 310 can be attached to the surface of the second glass body 112 facing the intermediate layer 113, and has a mounting surface 311 for attaching to the light source 200, and optionally, the mounting surface 311 is tilted relative to the surface of the first glass body 111 and the tilt angle is substantially the same as the tilt angle of the light source 200. Depending on different needs, the mounting frame 310 can 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 second glass body 112. For example, when the mounting frame 310 is arranged in a manner of being attached to the surface of the second glass body 112 facing the intermediate layer 113, the mounting frame 310 can 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 to Figure 1A In the existing manner shown, the glass assembly of the present disclosure not only satisfies the requirement that the incident light (especially the central light of the incident light) enters the glass body within a suitable angle range and has good total reflection in the glass body, avoids the existence of light attenuation, and improves the light utilization rate, but also reduces the placement space required for the light source and its mounting frame in the cross section of the glass assembly along the height direction, thereby 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 tilted and biased toward the second glass body, the glass assembly can also achieve the lighting effect (for example, it can be directed toward the interior of the vehicle), which will not be described in detail here.

[0053] Optionally or additionally, in order to achieve reliable fixation of the mounting frame, Figure 3A and Figure 3B In the manner shown, the mounting frame 310 can also be attached to the edge of the second glass body 112, and in some embodiments, the mounting frame 310 can also be attached to the surface of the second glass body 112 that is away from the intermediate layer 113. For example, when the mounting frame 310 is attached to the edge of the second glass body 112, the mounting frame 310 can be attached to the edges of the first glass body 111 and the second glass body 112 of the glass assembly at the same time, and be substantially flush with the surface of the glass assembly. The manner in which the mounting frame 310 is attached to the surface of the second glass body 112 that is away from the intermediate layer 113 can be, for example, referred to Figure 3BAs shown, the mounting frame 310 is attached to the surface of the second glass body 112 facing the middle layer 113, and is 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 to the surface of the second glass body 112 that is away from the middle layer 113. In this way, the mounting frame 310 is supported by the surface of the second glass body 112 facing the middle 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 that is away from the middle layer 113, and sufficient structural strength can be ensured. In this way, the lighting unit improves the light utilization while improving the space utilization, and ensures reliable fixation relative to the glass body.

[0054] In some embodiments, the edges of the first glass body 111 and / or the second glass body 112 are provided with a light-collecting surface. Figure 3A and Figure 3B In the embodiment shown, a focusing surface 114 is formed at the edge of the first glass body 111. The focusing surface 114 is configured to be an arc convex toward the light source 200, and a line connecting two ends of the arc of the focusing surface 114 ( Figure 3B The light source 200 is tilted relative to the surface of the first glass body 111 (shown by a dotted line in FIG. 1 ), and the tilt angle α is substantially the same as the tilt angle of the light source 200, that is, preferably, at least 43 degrees.

[0055] Above Figure 2 The light collecting surface 120 and Figure 3A and Figure 3B The light-collecting surface 114 shown 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 element arranged at the edge of the first glass body 111 and / or the second glass body 112, wherein the light-guiding element is provided with a light-guiding surface, and the light-guiding surface is configured as an arc convex toward the light source, and the connecting line of the two ends of the arc is inclined relative to the surface of the first glass body and / or the second glass body, and the inclination angle is substantially the same as the inclination angle of the light source 200, thereby being able to guide and collect the incident light. Compared with the process of precisely polishing the edge of the glass body to form a light-collecting surface, a light-guiding element with a desired shape is easier to manufacture.

[0056] exist Figure 4 In the illustrated embodiment, an attachment surface 115 is provided at the edge of the first glass body 111. The attachment surface 115 is, for example, substantially in the form of a plane and is configured to be inclined at an angle α relative to the surface of the first glass body 111, that is, substantially the same as the inclination angle of the light source 200. The light guide element 410 is configured to be attached to the attachment surface 115 and has a light guide surface 411 that is convex toward the light source 200 and is in an arc shape. Figure 5 In the illustrated embodiment, the edge of the first glass body 111 is provided with an attachment surface 116, and the attachment surface 116 is also configured as a substantially flat surface, but is different from Figure 4 In the embodiment shown, the attachment surface 116 in this embodiment is perpendicular to the surface of the first glass body 111. The light guide element 420 is configured to be attached to the attachment surface 116 and has a light guide surface 421 protruding toward the light source 200 in an arc shape. At the same time, the arc-shaped two-end line of the light guide surface 421 ( Figure 5 The angle α of the first glass body 111 (shown by a dotted line) is substantially the same as the angle of inclination of the light source 200. It should be understood that forming an attachment surface in the form of a substantially flat surface that is inclined to the glass body surface or perpendicular to the glass body surface at the edge of the glass body is easy to implement and also convenient for attachment to the light guide element. In any manner, the light guide element 410 or 420 can be attached to the attachment surface 115 or 116 at the edge of the first glass body 111 by, for example, an adhesive.

[0057] Advantageously, the materials of the light guide element and the adhesive in the above-mentioned embodiments are selected from materials with a refractive index close to that of the glass. For example, when the refractive index of the glass body is about 1.51, a material with a refractive index of about 1.51 is used, for example, about 1.49-1.52, so that when the incident light is transmitted to the glass body via the light guide element and the adhesive, the incident direction is basically unchanged. Alternatively, the material of the light guide element 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 glue (UV glue), thermosetting glue, unsaturated polyester glue, epoxy resin glue, polyurethane glue, organic silicone glue, and acrylic acid.

[0058] In such Fig. 6A In certain embodiments shown, the lighting unit may include a first light source 200a disposed at an edge of the first glass body 111 and tilted and offset, and a second light source 200b disposed at an edge of the second glass body 112 and tilted and offset. The first light source 200a and the second light source 200b may be disposed at edges of different sides of the glass component, respectively. For example, the tilt angle of the first light source 200a relative to the surface of the first glass body 111 may be consistent with the tilt angle of the second light source 200b relative to the surface of the second glass body 112. Accordingly, in Fig. 6AIn the illustrated embodiment, the mounting frame includes a first mounting frame 310a corresponding to the first glass body 111 and a second mounting frame 310b corresponding to the second glass body 112, and the first mounting frame 310a has a first mounting surface 311a for attaching to the first light source 200a, and the second mounting frame 310b has a second mounting surface 311b for attaching to the second light source 200b. Optionally, the first mounting surface 311a is inclined relative to the surface of the first glass body 111 and the inclination angle is substantially the same as the inclination angle of the first light source 200a, and the second mounting surface 311b is inclined relative to the surface of the second glass body 112 and the inclination angle is substantially the same as the inclination angle of the second light source 200b. By arranging the first light source and the second light source on the edges of different sides of the glass component, the mounting frames 310a and 310b can be as shown in FIG. Fig. 6A The first glass body 111 and the second glass body 112 are respectively arranged at the edges of the first glass body 111 and the second glass body 112, and can be combined as described above. Figure 3A The described manner is attached to the surface of the first glass body 111 and the second glass body 112 facing the intermediate layer 113, or is additionally attached to the edges of the first glass body 111 and the second glass body 112, or is additionally attached to the edges of the first glass body 111 and the second glass body 112 and has bonding portions 312a, 312b that can extend to the surfaces of the first glass body 111 and the second glass body 112 that are away from the intermediate layer 113.

[0059] Figure 6B The first light source 200a and the second light source 200b are exemplarily shown to be arranged at the edge of the same side of the glass component. In some optional embodiments, the first light source 200a and the second light source 200b can be arranged symmetrically, that is, the inclination angle of the first light source 200a relative to the surface of the first glass body 111 is consistent with the inclination angle of the second light source 200b relative to the surface of the second glass body 112. In the illustrated embodiment, the mounting frame 320 is configured to have a first mounting surface 321 for attaching to the first light source 200a and a second mounting surface 322 for attaching to the second light source 200b, optionally, the first mounting surface 321 is inclined relative to the surface of the first glass body 111 and the inclination angle is substantially the same as the inclination angle of the first light source 200a, and the second mounting surface 322 is inclined relative to the surface of the second glass body 112 and the inclination angle is substantially the same as the inclination angle of the second light source 200b. With the first light source and the second light source arranged at the edge of the same side of the glass assembly, the mounting frame 320 can be attached to the edges of the first glass body 111 and the second glass body 112, and has bonding portions 323, 324 that can extend to the surfaces of the first glass body 111 and the second glass body 112 that are away from the intermediate layer 113.

[0060] The above-mentioned method of providing light sources to the first glass body and the second glass body respectively can facilitate the effect of illuminating the exterior and interior of the vehicle at the same time. In some embodiments, the first glass body 111 can be configured to Figure 3A The embodiment shown in the figure has a light collecting surface 114, and the second glass body 112 can be configured as Figure 4 The embodiment shown is similarly provided with a light guide element 410. It should be understood that, depending on different needs, when 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 configured to have the same form or different forms, as long as the incident light emitted by the light source is focused into the glass body and the total reflection of the light in the glass body is achieved.

[0061] In each of the above embodiments, by arranging the light source at the edge of the glass body and tilting and biasing it toward the glass body, the glass assembly of the present disclosure provides an enhanced lighting effect while fully utilizing the light from the light source, and provides a relatively reduced installation volume of the light source and its mounting frame. The height dimension of the optimized lighting unit can be kept roughly consistent with that of a conventional single-layer glass body or laminated glass, and the edges are beautiful. In addition, compared to the method of integrating the light source into the glass body, the glass assembly of the present disclosure does not require processes such as opening holes in the glass body, which reduces light loss while ensuring the structural strength of the glass assembly. The lighting unit has a simple structure and is easy to assemble, thereby improving the user experience comfort and product market competitiveness.

[0062] It should be understood here that the embodiments shown in the figures only show the optional shapes, sizes and arrangements of the various optional components of the glass assembly according to the present disclosure, but they are only illustrative and not restrictive, and other shapes, sizes and arrangements may also be adopted without departing from the spirit and scope of the present disclosure.

[0063] The technical content and technical features of the present disclosure have been disclosed above. However, it can be understood that under the creative ideas of the present disclosure, technicians in this field can make various changes and improvements to the above disclosed concepts, but they all belong to the protection scope of the present disclosure. The description of the above implementation mode is illustrative rather than restrictive, and the protection scope of the present disclosure is determined by the claims.
