[0039] 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 present 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.
[0040] In this context, the expression "comprising" or similar expressions "including" , "containing" and "having" which are synonymous are open, and do not exclude additional unlisted elements, steps or ingredients. The expression "consisting of …" excludes any element, step or ingredient that is not specified. The expression "consisting essentially of …" means that the scope is limited to the specified elements, steps or ingredients, plus the optional elements, steps or ingredients that do not materially affect the basic and new features of the claimed subject matter. It should be understood that the expression "comprising" covers the expressions "consisting essentially of" and "consisting of" .
[0041] 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.
[0042] In this context, the meanings of "aplurality of" and "multiple layers" refer to two or more than two, unless otherwise specified.
[0043] In this context, unless otherwise specified, the terms such as "installation" , "connection" and "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.
[0044] In the described embodiments, the thickness of the glass body is generally used in the art, and the thickness of each laminated structure on the glass body is applicable to the conventional range, and is not limited by the details shown in the figures and described below. In addition, although it is shown as plane glass in the figures, the glass body of the present disclosure may also be curved glass. In various embodiments, it is described as an independent glass body, however, in some cases, the surface of the glass body can also use special coating layer to improve thermal insulation and / or comfort and so on, and the glass body can also be a laminated glass to obtain diversified functions or effects.
[0045] Hereinafter, the glass assembly applied to a vehicle window glass will be described, but it does not exclude that the glass assembly can be applied to other environments such as door, window, curtain wall, 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. "Front" and "rear" are relative to the direction of vehicle travel, "front" refers to the direction towards the direction of vehicle travel, and "rear" refers to the direction away from the direction of vehicle travel. 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 luminous effects based on different requirements.
[0046] In the automobile industry where entertainment and comfort are ever increasing, a glass with luminous effect has been applied to such as vehicle skylight or windshield of mid-to-high-end vehicles, to provide decorative effect in the form of pattern. Generally, the pattern can be presented on the glass by projection (for example, putting picture or video advertisement on the rear windshield) or by illuminating the pattern on the glass by a light source. It has been realized that the projection mode is highly flexible, and any desired pattern can be projected on the glass as required. However, in this mode, an imaging structure on the glass including fluorescent material, microstructure, projection film and the like should be combined with a vehicle-mounted projector. The vehicle-mounted projector is difficult to be located inside the vehicle, and the projected image will be unstable due to vibration during the driving of the vehicle. The illumination mode of the light source is to illuminate an original pattern on the glass, which is clearer and more stable than the projection mode. However, there is still a technical restriction on the arrangement of the light source, especially the organic light emitting diode (OLED) is difficult to be laminated in the glass, with high cost and limited application range. Furthermore, even if different lighting effects can be achieved by controlling brightness and / or color of the light source, the observed pattern or color is monotonous. Therefore, the existing lighting glass can not satisfy the manufacturers and the consumers.
[0047] In order to obtain a visual effect different from the conventional monotonous pattern and provide a simple, stable and low-cost information display system through the glass, the present disclosure provides a glass assembly. The glass assembly comprises a glass body provided with a light extraction structure, and incident light introduced into the glass body is extracted and led out from the glass body; wherein the glass assembly further comprises a lighting control unit, and the lighting control unit is connected with an external control unit in electrical communication to illuminate and dynamically display a pattern formed by the light extraction structure in response to a control signal of the external control unit.
[0048] With the above solution, the glass assembly of the present disclosure makes it possible to provide dynamic information of changing modes on the glass body in real time, and the dynamic information can present different changing pattern effects or superposition effect of multiple patterns depending on different application occasions and different control strategies of the lighting control unit and / or the external control unit. Furthermore, by changing the design of the formation mode of the light extraction structure on the glass body and the pattern formed by the light extraction structure, and / or changing the design of different light sources for emitting the incident light (such as color, lighting intensity, dynamic transformation effect, etc. ) , the glass assembly can obtain unpredictable and rich visual effect. Compared with the existing monotonous patterns, the glass assembly of the present disclosure brings different sensory experiences to the consumers. For example, for the pattern formed by the light extraction structure, the conventional glass assembly can only provide the effect of illuminating and / or changing the color of the pattern, and the visual effect is single. However, the glass assembly of the present disclosure can dynamically display the pattern in response to the control signal of the external control unit, including but not limited to fully illuminating, partially illuminating or gradually illuminating the pattern, and / or changing the color of portion of the pattern or all the pattern, etc., thus realizing the display effect of updating information through pattern change, and thus being particularly suitable for the application occasions requiring real-time display of information.
[0049] In this context, the lighting control unit refers to a control module, for example, a lighting electronic control unit (lighting ECU) , that controls the lighting of the pattern formed by the light extraction structure on the glass body. When the glass assembly includes a light source, the lighting control unit is coupled to the light source and can be configured to control output intensity and / or output time of one or more light sources for controlling the lighting type, pattern lighting sequence and the like. The external control unit refers to a control module which is adapted to be connected with the lighting control unit in electrical communication and provides a control signal so that the lighting control unit can illuminate and dynamically display the pattern formed by the light extraction structure in response to the control signal. When the glass assembly is applied to a vehicle, the external control unit includes, for example, a vehicle control unit. Here, the vehicle control unit includes any control unit on the vehicle side, such as a central control unit, an in-vehicle entertainment system, a vehicle body control unit, and the like. In this context, the expression "connected in electrical communication" refers to the use of electrical signals as the carrier of information transmission, such as changing the frequency of electromagnetic wave for information transmission, which usually includes wired communication and wireless communication.
[0050] Advantageously, the lighting control unit is connected with the external control unit in electrical communication through an external interface and / or a wireless transceiver. Optionally, the external interface includes, but is not limited to, USB interface, HDMI interface, etc., and the wireless transceiver includes, for example, Wi-Fi chip, Bluetooth chip, etc., so that the lighting control unit can wirelessly communicate with a remote control unit having wireless communication function except for the vehicle control unit. The remote control unit includes, but is not limited to, mobile terminal such as smart phone, tablet computer and laptop computer. Communication protocol includes but is not limited to Ethernet, LIN, CAN, Melibus, ISELED or other types of transmission buses.
[0051] Figs. 1A to 1D illustrate different embodiments of a pattern presented by a glass assembly of the present disclosure. In the shown embodiments, the glass body of the glass assembly can be a monolithic glass or a laminated glass. Here, taking a surface of a monolithic glass body 10 as an example. The lighting control unit, for example, controls the light source, so that the incident light emitted by the light source is introduced into the glass body 10 and extracted and led out from the glass body 10 at the light extraction structure, thereby displaying a pattern formed by the light extraction structure on the surface of the glass body 10. Fig. 1A illustrates a pattern 20a continuously arranged along the glass body 10, and Fig. 1B illustrates a pattern 20b dispersedly arranged along the glass body 10. Fig. 1C also illustrates a pattern 30a continuously arranged along the glass body 10, and the pattern 30a gradually changes the size along the glass body 10 compared with the pattern 20a shown in Fig. 1A. Fig. 1D is similar to Fig. 1C, but the difference is that the pattern 30b in Fig. 1D gradually changes the color along the glass body 10, which can be realized by designing the light extraction structure itself (such as enamel color) or the light source (such as color and / or intensity of the light source) .
[0052] It should be understood that the pattern designs shown in Figs. 1A to 1D are only examples, and depending on different requirements, a plurality of light extraction structures, different sizes and distributions, and the superposition of the light extraction structures arranged continuously or discontinuously are all feasible, so that different display patterns or display effects can be generated through different designs. Alternatively, the pattern formed by the light extraction structure includes at least one of texture, graphic, character, symbol, number, beacon and trademark. In some embodiments, the pattern formed by the light extraction structure is fully illuminated, partially illuminated or gradually illuminated according to the control signal of the external control unit, which will be described in detail in connection with specific embodiments.
[0053] It should be understood that the light extraction structure is microstructure or micro-texture, and the size is in the micron or even nanometer level. When the glass assembly includes a light source, the incident light emitted by the light source is totally reflected in the glass body and reflected, scattered or diffused after contacting the light extraction structure, thus achieving the lighting effect, which is an indirect lighting mode. With the indirect lighting mode, the richer lighting effect can be obtained through different control strategies of the light source (such as color, quantity, distribution, lighting intensity and / or lighting time) , such as at least one of monochromatic lighting, multicolor lighting, continuous lighting, flashing lighting, flowing lighting and breathing lighting. In some embodiments, the light extraction structure may include electroluminescent material and be connected to the lighting control unit. In this way, the lighting control unit directly makes the light extraction structure electroluminescent, which is a direct lighting mode.
[0054] No matter what lighting mode is adopted, it is advantageous that the light extraction structure is formed or embedded in the glass body, or the light extraction structure is formed on the surface of the glass body.
[0055] In some embodiments, the light extraction structure is formed in the glass body by laser engraving. Compared with sand blasting, screen printing, etching and other technologies to form the light extraction structure on the surface of the glass, the pattern formed by internal engraving can significantly improve the illumination brightness. Whether in a test environment with sufficient light or a test environment with dimly light, the pattern can be clearly seen when the light source is turned on, and the glass becomes transparent or translucent when the light source is turned off without affecting the perspective function. In some embodiments, the light extraction structure is formed on the surface of the glass body by laser engraving or printing or in the form of film layer. As for the printing method, materials such as enamel or ink can be printed on the surface of the glass body by screen printing or inkjet printing. As for the form of film layer, a light extraction film can be used, for example, a light extraction film including a substrate of polyethylene terephthalate (PET) and a light extraction structure formed on the substrate.
[0056] In some embodiments, the glass assembly includes a light source arranged adjacent to an edge and / or a surface of the glass body or embedded in the glass body, and the light source is connected to the lighting control unit.
[0057] Figs. 2A to 2D illustrate several different forms of the light source. Alternatively, the light source is, for example, a point or linear light source integrated inside the glass body, or a light source 40 attached to the edge of the glass body in a manner of proximity, bonding, etc., for example, a light-emitting strip welded with a plurality of LEDs 41 as shown in Fig. 2A, or a point LED with a light guide, for example, LEDs 41 located at both ends of a light guide 42 as shown in Fig. 2B. When a plurality of LEDs are used, these LEDs can be selected to be the same as or different from each other, so as to achieve richer optical effects. For example, when different colors are used, the gradient effect of multiple colors in Fig. 1D can be obtained, and when a plurality of LEDs with the same color are used, the gradient effect in Fig. 1D can be obtained through the change of lighting intensity. In addition, as mentioned above, the lighting effect of dynamic display such as flashing lighting, flowing lighting and breathing lighting can be realized by the light source. In some embodiments, for example, by setting different lighting time and / or interval time of the plurality of LEDs, the display effect of dynamic flashing or bright-dark flashing can be realized by using a star pattern, so that the dynamic visual effect of star flashing can be obtained. Flowing lighting or breathing lighting can also be set up similarly, which will not be described here.
[0058] Alternatively, the LED 41 may be located on one side surface of the light guide 42, for example, on the lower side surface of the light guide 42 as shown in Fig. 2C. Alternatively, the light source can adopt a rotating LED module, that is, the rotation of the LED 41 in the arrow direction as shown in Fig. 2D is realized by rotating a driving component 43. Correspondingly, the glass body or the light guide is provided with a structure for the LED to rotate, such as a channel.
[0059] In some embodiments, the glass body is provided with one or more light sources. In an embodiment shown in Fig. 3A, the edge and one side surface of the glass body 10 are respectively provided with a light source 40, and any one shown in Figs. 2A to 2D can be used as the light source 40.
[0060] In some embodiments, the glass assembly includes a light guiding component attached to the edge and / or the surface of the glass body, and the incident light emitted by the light source enters the glass body via the light guiding component. This way can reduce the light loss and make the luminous visual effect better. Alternatively, the light guiding component includes any one of prism, lens and microstructure film layer.
[0061] In an embodiment shown in Fig. 3B, a light guiding component 50a in the form of prism is provided, and the light guiding component 50a has a triangular cross section, for example. It should be understood that the cross section of the light guiding component 50a may take other shapes than triangular according to actual requirements.
[0062] In another embodiment shown in Fig. 3C, a light guiding component 50b is in the form of microstructure film layer, and the light focusing effect can be obtained through the microstructure to reduce the illumination loss of the incident light. Certainly, a light guiding component in the form of lens can also achieve the light focusing effect.
[0063] In some embodiments, the light guiding component can be installed with the light source through a mechanical structure or an adhesive, so as to be integrated to simplify assembly. In some embodiments, the light guiding component may be attached to the glass body by the adhesive. Alternatively, the material of the light guiding component includes but is not limited to glass, polymethylmethacrylate (PMMA) , cycloolefin plastic or alicyclic methacrylate copolymer, and the adhesive includes but is not limited to ultraviolet (UV) adhesive, optical adhesive (OCA) or acrylic acid.
[0064] Figs. 4A to 4C respectively illustrate a pattern effect that can be presented when the light extraction structure includes electroluminescent material. Taking the application of the glass assembly to the vehicle window glass as an example, the pattern or information displayed on the glass body 10 may include but not limited to vehicle status information such as battery capacity, vehicle speed and driving mode. In Fig. 4A, a pattern 62 on the glass body 10 indicates a vehicle lane, and a pattern 63 indicates the departure from the vehicle lane. The two patterns are respectively connected to a lighting control unit 61 and can be electroluminescent, thus obtaining the function of lane auxiliary alarm. In Fig. 4B, a pattern 64 on the glass body 10 is a lightning mark, for example, for providing warning function, a pattern 65 is a cyclic mark, for example, for indicating working state of a ventilation system, and a pattern 66 is a smiling face mark, for example, for indicating that the warning is released. A pattern 67 in Fig. 4C is a welcome sign, in which each letter in "Welcome" can be connected to the lighting control unit 61 respectively, that is, the pattern is formed by a plurality of electroluminescent segments, and each electroluminescent segment can be controlled separately, so that various effects such as different letters gradually brighten, different letters with different brightness and / or colors, and different letters flicker can be obtained. It should be understood that, depending on different requirements, the patterns shown in Figs. 4A to 4C can also be displayed by illumination of the light source as mentioned above, and different patterns can be superimposed on the glass body to be displayed separately or simultaneously.
[0065] As mentioned above, the glass body in the glass assembly can be a monolithic glass or a laminated glass. In the embodiment of laminated glass, as shown in Fig. 5, a glass assembly 100 includes a first glass body 110 and a second glass body 120 attached to the first glass body 110 through an intermediate layer, wherein a light extraction structure is attached to a surface of the first glass body 110 and / or the second glass body 120 by laser engraving or printing or in the form of film layer, or is formed in the first glass body 110 and / or the second glass body 120 by laser engraving or in the form of film layer.
[0066] For the vehicle window glass, for example, the first glass body 110 faces the outside of the vehicle, which can be called external glass, and the second glass body 120 faces the inside of the vehicle, which can be called internal glass. The surface of the first glass body 110 and / or the second glass body 120 with the light extraction structure may be a surface facing the outside of the vehicle or a surface facing the inside of the vehicle. In this way, the lighting control unit of the glass assembly dynamically displays a pattern formed by the light extraction structure to the outside and / or the inside of the vehicle in response to a control signal of the external control unit. Alternatively, the first glass body or the second glass body is any one of ordinary glass, ultra-transparent glass, ultra-thin glass and flexible glass.
[0067] When the light extraction structure in the form of film layer is adopted, a light extraction structure 150 is attached to the first glass body 110 through a first intermediate layer 130 and attached to the second glass body 120 through a second intermediate layer 140, respectively. For those skilled in the art, the intermediate layer is usually an adhesive layer in the glass assembly which plays an adhesive role, and the first intermediate layer 130 and the second intermediate layer 140 include, but are not limited to, adhesive layer suitable for the laminated glass such as polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) . As an example, the light extraction structure 150 may be an electroluminescent material film layer, including a pattern formed on the film layer.
[0068] In some embodiments, the first glass body 110 or the second glass body 120 is tinted glass, for example, it may have a gray scale. Compared with transparent glass, the glass assembly can display pattern effect only towards the inside of the vehicle or only towards the outside of the vehicle, so as to meet different information display requirements. In some embodiments, the first intermediate layer 130 or the second intermediate layer 140 may also have a gray scale, thereby achieving different display effects.
[0069] Figs. 6A to 9 respectively illustrate different embodiments of displaying, for example, vehicle state information through the glass body 10. It should be understood that the light extraction structure forming the pattern in these embodiments can display the pattern by illumination of the light source or by electroluminescence.
[0070] Figs. 6A to 6D illustrate, for example, a real-time change of the battery state of charge, and the battery state of charge is updated in real time through the dynamic change of the pattern 20a on the glass body 10. In Fig. 6A, the pattern 20a is fully illuminated, showing 100%power and showing a certain color (e.g. blue color) . When the battery power is reduced, the length of the illuminated portion of the pattern 20a is shortened accordingly, for example, the length of the illuminated portion in Fig. 6B shows 80%power and the length of the illuminated portion in Fig. 6C shows 60%power. When the battery power is lower than a certain level, for example, the power is less than or equal to 20%, the pattern 20a can be transformed into the pattern 20c with different colors (for e.g., red color) , as shown in Fig. 6D, thus serving as an alarm.
[0071] Figs. 7A and 7B illustrate, for example, a real-time change of the vehicle speed state, and the vehicle speed state is updated in real time through the dynamic change of the pattern 30a on the glass body 10. In Fig. 7A, the pattern 30a is gradually illuminated in the arrow direction with the increase of vehicle speed and appears in a certain color (e.g. blue color) , or gradually darkens or is not illuminated in the opposite direction of the arrow with the decrease of vehicle speed. When the speed exceeds the limit, the pattern 30a may be changed to the pattern 30c of a different color (e.g., red color) to serve as an alarm. Alternatively, the pattern 30c can flash to give the alarm, so that the alarm information can be displayed to the driver, for example, through the front windshield or the vehicle door glass when the vehicle speed is too high, or the alarm information can be displayed to the driver of the following vehicle, for example, through the rear windshield when the vehicle speed is too low, so as to facilitate timely response to emergencies.
[0072] Fig. 8 illustrates a real-time change of the driving state of the vehicle along the vehicle lane, and the driving state of the vehicle along the vehicle lane is updated in real time through the dynamic change of the patterns 62 and 63 on the glass body 10. When the vehicle is driving normally along the vehicle lane, only the pattern 62 (which can also be a certain color, such as blue color) is displayed. When the vehicle deviates from the vehicle lane, the pattern 63 (which can also be a different color, such as red color) is illuminated to provide an auxiliary alarm.
[0073] Fig. 9 illustrates a changing state of the greeting message in the welcome mode, and the greeting message is displayed in real time through the dynamic change of the pattern 67 on the glass body 10. As an example, the letters in the greeting message "Welcome" can be illuminated gradually in the direction of the arrow.
[0074] It should be understood that the above examples are not exhaustive of alternative embodiments, and any other suitable combination of variations is feasible based on the concept of the present disclosure. For example, the pattern displayed on the glass body can include but not limited to information such as weather, fuel quantity, tire pressure, etc., or the decoration and entertainment functions required by the driver or passengers can be customized by the owner. In addition, for the light extraction structure, in addition to the changes in the formation mode, size and arrangement position, in the way of printing enamel or ink on the surface of the glass to form patterns, the color of enamel or ink material can also be changed according to different requirements, and different display effects can be achieved through different materials with different colors.
