[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort belong to the scope of protection of the present application.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0025] It will be understood that, as used in the present application, the terms "first", "second", etc. can be used herein to describe various elements, but the elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first resistor could be termed a second resistor, and, similarly, a second resistor could be termed a first resistor, without departing from the scope of the present application. The first resistor and the second resistor are both resistors, but they are not the same resistor.
[0026] It will be understood that when an element is referred to as being "on" or "connected to" another element, it can be directly on the other element or intervening elements can also be present. In this document, relative terms such as "vertical", "horizontal", "up", "down", "left", "right", and the like are used to describe the orientation of elements in the drawings as presented. These terms are used only to facilitate the description of the embodiments.
[0027] In the description of the present application, it should be understood that "electrically connected" in the present application can be understood as that the components are in physical contact and electrically conductive; it can also be understood as the form of connection between different components in the circuit structure through the entity line such as copper foil or wire of printed circuit board (PCB) that can transmit electrical signals.
[0028] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. When the expression such as "at least one of (a), (b), and (c)" follows a list of elements (elements), the expression "at least one of (a), (b), and (c)" modifies the entire list of elements and does not modify the individual elements of the list.
[0029] It should also be understood that the terms "comprise / comprising" or "have / having" or the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.
[0030] It should also be understood that, in interpreting elements, although not expressly described, the elements are interpreted to include an acceptable range of error around the specific value that should be determined by one of ordinary skill in the art. For example, "about", "approximately", or "substantially" can mean within one or more standard deviations, without being limited thereto.
[0031] With the increasing intelligence of vehicles, the glass on the vehicle is gradually integrated with more functions, such as single-function glass products such as luminous glass, dimming glass, heat-insulating glass, and combined glass products with multiple functions stacked together. However, when multiple functions are stacked together, sometimes there is mutual influence between certain two functions, and not every function is independent and not affected by other functions after stacking. Some of these influences are positive, and some are not.
[0032] In the related art, the glass product combining the luminous function and the heat-insulating function, that is, the glass product combining the atmosphere luminous function in the luminous glass and the low-emissivity coating function in the heat-insulating glass, can be called a glass assembly. The low-emissivity film layer in such a glass assembly needs to consider both reducing heat radiation and reducing reflection. Since the development of the low-emissivity film layer mainly considers reducing heat radiation, the function of reducing reflection is added on the basis of reducing heat radiation, and the influence of the conduction and diffuse reflection of visible light on the glass substrate on the deposition surface of the low-emissivity film layer is not considered. The visible light transmittance of the low-emissivity film layer is generally 65%. In terms of the actual combination effect, coating the low-emissivity film layer on the glass has an adverse effect on the brightness and color of the final glass assembly. As shown in Table 1, compared with the glass assembly without the low-emissivity film layer, the low-emissivity film layer weakens the brightness of the glass assembly when it emits light, and also causes a deviation in color.
[0033] In Table 1, the brightness values at different positions before and after coating the low-emissivity film layer in the related art are compared for the glass assembly shown in FIG. 1. The brightness values at 9 positions on the same straight line in the glass assembly are simulated. The brightness value of the glass assembly when it emits light without the low-emissivity film layer is taken as the standard brightness value, and the brightness value of the glass assembly when it emits light with the low-emissivity film layer is taken as the real brightness value. The brightness difference degree of the real brightness value and the standard brightness value at different positions is calculated by the following brightness difference degree calculation formula. The unit of the brightness value is: cd / m2.
[0034] Brightness difference degree = (standard brightness value - real brightness value) / standard brightness value x 100%
[0035] Table 1
[0036] Based on this, it is necessary to propose effective technical means to solve the problem of brightness attenuation and color deviation caused by the low-emissivity film layer to the glass assembly. The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail in the following specific embodiments. In addition, the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0037] In one embodiment, as shown in FIG. 2, a schematic cross-sectional view of a glass assembly is provided, which includes a laminated glass piece 201, a low-emissivity film layer 202, and a light output layer 203. The laminated glass piece 201 includes a first glass piece 2011 and a second glass piece 2012 arranged in a stack; the low-emissivity film layer 202 is arranged on a side of the first glass piece 2011 away from the second glass piece 2012; and the light output layer 203 is arranged on the laminated glass piece 201. It should be noted that the glass assembly in FIG. 1 has the same structure as the glass assembly shown in FIG. 2.
[0038] Optionally, the laminated glass piece 201 is a sunroof, a front windshield, a rear windshield, or a side window. The laminated glass piece 201 includes a first glass piece 2011, a second glass piece 2012, and a first bonding layer 2013; wherein the first bonding layer 2013 is arranged between the first glass piece 2011 and the second glass piece 2012. The first glass piece 2011 includes a first side and a second side, and the second glass piece 2012 includes a third side and a fourth side; the first side is away from the third side, and the second side is close to the third side; the third side is close to the second side, and the fourth side is away from the second side. When the laminated glass piece 201 is installed on a vehicle, the first side, the second side, the third side, and the fourth side are respectively viewed from an interior space of the vehicle to an exterior of the window. The first bonding layer 2013 can be made of PVB (Polyvinyl Butyral), which can adhere the first glass piece 2011 and the second glass piece 2012 together through a lamination process to form the laminated glass piece 201, and can effectively improve the strength and toughness of the laminated glass piece 201, and can also improve the anti-collision ability and safety performance of the laminated glass piece 201.
[0039] The light output layer 203 can be a light-reflecting plate. The light output layer 203 can be arranged on the second side of the first glass piece 2011, i.e., between the first glass piece 2011 and the first bonding layer 2013; or can be arranged on the first side of the first glass piece 2011; or can be arranged in the first glass piece 2011. The specific arrangement position of the light output layer 203 on the laminated glass piece 201 is not limited herein. It should be noted that when the light output layer is arranged on the first side of the first glass piece 2011, the low-emissivity film layer 202 is arranged on a side of the light output layer 203 away from the first glass piece 2011.
[0040] The orthographic projection of the light output layer 203 on the first glass piece 2011 covers at least part of the area of the first glass piece 2011, i.e., covers part of the area or the whole area of the first glass piece 2011. In FIG. 2, the orthographic projection of the light output layer 203 on the first glass piece 2011 covers part of the area of the first glass piece 2011, and the light output layer 203 is arranged on the second surface of the first glass piece 2011. In FIG. 2, the light output layer 203 is represented by a dashed line.
[0041] Regardless of the position of the light output layer 203, the purpose is to emit the light conducted in the first glass piece 2011 from the side of the first glass piece 2011 away from the second glass piece 2012, so as to achieve the light-emitting effect of the glass assembly. The source of the light conducted in the first glass piece 2011 can come from the light guide assembly 204 and the light source 205. The light guide assembly 204 and the light source 205 can be arranged on the side of the low-emissivity film layer 202 away from the first glass piece 2011, or can be arranged on the side surface of the first glass piece 2011 (the side surface refers to any surface of the first glass piece 2011 intersecting the first surface and the second surface).
[0042] Taking the light output layer 203 arranged on the second surface of the first glass piece 2011 and the light guide assembly 204 and the light source 205 arranged on the side of the low-emissivity film layer 202 away from the first glass piece 2011 as an example, the light-emitting principle of the glass assembly is as follows:
[0043] The light guide assembly 204 guides the light from the light source 205 onto the low-emissivity film layer 202, the low-emissivity film layer 202 refracts the light to the first glass piece 2011, and the light is conducted in the first glass piece 2011. The light output layer 203 reflects the light emitted from the first glass piece 2011 back to the first glass piece 2011, and then the light is emitted from the first surface of the first glass piece 2011, achieving the light-emitting effect of the glass assembly.
[0044] The visible light transmittance of the low-emissivity film layer 202 is 88% to 92%, which is used for reflecting infrared rays, i.e., blocking the convection of infrared rays inside and outside, and reducing the transfer of heat. For example, the visible light transmittance of the low-emissivity film layer 202 can be, but is not limited to, 88%, 88.5%, 89%, 89.5%, 90%, 90.5%, 91%, 91.5%, 92%, or a range formed by any two of these values.
[0045] As can be seen from Table 2, Table 3, Table 4 and FIG. 3, the visible light transmittance of the low-emissivity film layer 202 is 88% to 92%, which can greatly improve the brightness and reduce the color deviation of the glass assembly when emitting light. The brightness of the glass assembly when emitting light is represented by the brightness value, and the color of the glass assembly when emitting light is represented by the color coordinate.
[0046] Table 2 is a table of the comparison of the luminance values at different positions and the standard luminance value (the luminance value of the glass assembly without the low-emissivity film layer) when the visible light transmittance of the low-emissivity film layer 202 is 65%, 75%, 88%, 91.5% and 92% respectively for the glass assembly shown in Fig. 1.
[0047] Table 3 is a table of the comparison of the color coordinates at different positions and the standard color coordinates (the color coordinates of the glass assembly without the low-emissivity film layer) when the visible light transmittance of the low-emissivity film layer 202 is 65%, 75%, 88%, 91.5% and 92% respectively.
[0048] Table 4 is a table of the comparison of the average color coordinates of the glass assembly and the standard color coordinates when the visible light transmittance of the low-emissivity film layer 202 is 65%, 75%, 88%, 91.5% and 92% respectively, and the color coordinate difference degree of the average color coordinates and the standard color coordinates is calculated by the following color coordinate difference degree calculation formula.
[0049] Color coordinate difference degree = (standard color coordinates - average color coordinates) / standard color coordinates x 100%
[0050] Fig. 3 is a comparison diagram of the glass assembly when the visible light transmittance of the low-emissivity film layer 202 is 65%, 75%, 88%, 91.5% and 92% respectively.
[0051] Table 2
[0052] Table 3
[0053] Table 4
[0054] Therefore, the glass assembly comprises a laminated glass piece 201, a low-emissivity film layer 202 and a light output layer 203. The laminated glass piece 201 comprises a first glass piece 2011 and a second glass piece 2012 arranged in a stack. The low-emissivity film layer 202 is arranged on a side of the first glass piece 2011 away from the second glass piece 2012. The light output layer 203 is arranged on the laminated glass piece 201 and is configured to emit light conducted in the first glass piece 2011 from a side of the first glass piece 2011 away from the second glass piece 2012. The visible light transmittance of the low-emissivity film layer 202 is 88% to 92%. The low-emissivity film layer with a visible light transmittance of 88% to 92% can improve the luminance of the glass assembly when emitting light and reduce color deviation.
[0055] In an exemplary embodiment, the thickness of the low-emissivity film layer 202 is less than or equal to about 200 nm.
[0056] The low-emissivity film layer 202 is a composite film layer, i.e., a plurality of film layers are stacked together. Some film layers in a conventional low-emissivity film layer that affect the visible light band can be reduced through multiple experiments to obtain the low-emissivity film layer 202 with a visible light transmittance of 88% to 92%. It should be noted that the specific structure of the conventional low-emissivity film layer is various. For different conventional low-emissivity film layers, the specific film layers to be reduced are different. The film layers to be reduced can be determined through multiple experiments. Therefore, the specific structure of the low-emissivity film layer 202 is not limited herein.
[0057] The thickness of the conventional low-emissivity film layer is generally greater than or equal to about 210 nm. Through multiple experiments, the thickness of the low-emissivity film layer 202 is generally reduced by about 10 nm to 50 nm compared to the thickness of the conventional low-emissivity film layer to achieve a visible light transmittance of 88% to 92%. That is, the thickness of the low-emissivity film layer 202 is less than or equal to about 200 nm. Optionally, the thickness of the low-emissivity film layer 202 is less than or equal to about 190 nm. Optionally, the thickness of the low-emissivity film layer 202 is less than or equal to about 190 nm and greater than or equal to about 160 nm.
[0058] In this embodiment, the thickness of the low-emissivity film layer 202 is less than or equal to 200 nm. In this way, the visible light transmittance of 88% to 92% is achieved while the purpose of reducing heat radiation is also achieved.
[0059] In an exemplary embodiment, the reflection color of the surface of the first glass piece 2011 provided with the low-emissivity film layer 201 has a color component L value of 28 to 38, a color component A value of -1 to 1, and a color component B value of -1 to 1 in the LAB color space.
[0060] Optimizing the reflection color of the low-emissivity film layer 201 reduces the influence of the low-emissivity film layer 201 on light, which is crucial to solving the color deviation of the glass assembly when emitting light. The reflection color can be represented by LAB values. Optimizing the reflection color of the low-emissivity film layer 201 can be to optimize the LAB values of the surface of the first glass piece 2011 provided with the low-emissivity film layer 201 to the LAB values of the first glass piece 2011 without the low-emissivity film layer 201.
[0061] The first glass piece 2011 without the low-emissivity film layer 201 is neutral color. The LAB values corresponding to the neutral color are used as the standard LAB values. As shown in Table 5, for the cases where the visible light transmittance of the low-emissivity film layer 202 is 65%, 75%, 88%, 91.5%, and 92%, respectively, the comparison table of the LAB values of the surface of the first glass piece 2011 provided with the low-emissivity film layer 201 and the standard LAB values.
[0062] Table 5
[0063] As can be seen from Table 5, three sets of LAB values are measured for the low-emissivity film layer 202 with different visible light transmittances, and in fact there are more sets of LAB values which are not listed here, which is caused by the instability of the production process of the existing low-emissivity film layer, and the stability tolerance of the production process of the existing low-emissivity film layer is: L = ± 4, A = ± 1, B = ± 1. In combination with the LAB values of the low-emissivity film layer with different visible light transmittances in Table 5 and the production process of the existing low-emissivity film layer, in the LAB values of the surface of the first glass piece 2011 provided with the low-emissivity film layer 201, the L value can be 28-38, the color component A value can be -1-1, and the color component B value can be -1-1.
[0064] In the embodiment, the reflective color of the surface of the first glass piece provided with the low-emissivity film layer 201 is in the LAB color space, the color component L value is 28-38, the color component A value is -1-1, and the color component B value is -1-1, which is close to the LAB value of the neutral color, which can reduce the color deviation when the glass assembly emits light.
[0065] In an exemplary embodiment, the first glass piece 2011 is super white glass, and super white glass with a visible light transmittance of 88%-93% is selected, that is, the visible light transmittance of the super white glass can be but is not limited to 88%, 89%, 90%, 91%, 92%, 93%, or a range composed of any two of these values, which can further improve the brightness of the glass assembly when it emits light, and reduce the color deviation when the glass assembly emits light.
[0066] In an exemplary embodiment, the first adhesive layer 2013 can be selected from materials with a visible light transmittance of 80%-98%, such as light-colored PVB with a visible light transmittance of 80%-98%. That is, the visible light transmittance of the first adhesive layer 2013 can be but is not limited to 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, or a range composed of any two of these values. The thickness of the first adhesive layer 2013 can be 0.38 mm or 0.76 mm.
[0067] It is found in the experiment that, under the condition that other conditions are the same, changing the visible light transmittance of the first bonding layer 2013 will also cause the brightness of the glass assembly to change when the glass assembly emits light. As shown in Table 6, Table 6 is a comparison table of the brightness value of the glass assembly when the glass assembly emits light under the condition that the visible light transmittance of the first bonding layer 2013 is 18%, 60%, 80%, 88%, and 98%. It can be seen that the higher the visible light transmittance of the first bonding layer 2013, the higher the brightness value of the glass assembly when the glass assembly emits light. Based on the comparison of the brightness value in Table 6, the first bonding layer 2013 with a visible light transmittance of 80% to 98% is selected. It should be noted that the brightness measurement position of the glass assembly in Table 6 is the same as the position shown in FIG. 1.
[0068] Table 6
[0069] In an exemplary embodiment, as shown in FIG. 4, a second bonding layer 2014 is arranged between the second glass piece 2012 and the first bonding layer 2013, so that the visible light transmittance of the glass assembly is less than or equal to a preset visible light transmittance.
[0070] The preset visible light transmittance can be the visible light transmittance of the glass required by the glass design specification. The second bonding layer 2014 can be made of a material with a visible light transmittance less than that of the first bonding layer 2013. Optionally, the material with a visible light transmittance greater than or equal to 60% and less than 80% can be selected, for example, a dark PVB with a visible light transmittance of 60% to 80%. That is, the visible light transmittance of the second bonding layer 2014 can be, but is not limited to, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, or a range formed by any two of these values.
[0071] The thickness of the second bonding layer 2014 can be 0.38 mm or 0.76 mm. In the case where the second bonding layer 2014 is arranged between the second glass piece 2012 and the first bonding layer 2013, the thickness of the second bonding layer 2014 and the first bonding layer 2013 is 0.38 mm.
[0072] In this embodiment, for different uses of glass, the glass design specification requires the visible light transmittance of the glass to be in different ranges, that is, the designed glass needs to meet the optical index. For example, for the glass installed on a vehicle, the glass design specification requires the visible light transmittance of the glass to be between 50% and 90%. Therefore, in the case where the first glass piece 2011, the first bonding layer 2013, and the low-emissivity film layer 202 in the glass assembly are all high-transmittance, the second bonding layer 2014 needs to be arranged to make the glass assembly meet the optical index.
[0073] In an exemplary embodiment, as shown in FIG. 5, the glass assembly further comprises an infrared reflection film layer 501, which is arranged between the first adhesive layer 2013 and the second glass piece 2012 to reflect infrared rays.
[0074] Optionally, based on the glass assembly shown in FIG. 2, i.e. without the second adhesive layer 2014, the infrared reflection film layer 501 is arranged between the first adhesive layer 2013 and the second glass piece 2012; based on the glass assembly shown in FIG. 4, i.e. with the second adhesive layer 2014, the infrared reflection film layer 501 is arranged between the second adhesive layer 2014 and the second glass piece 2012. The arrangement position of the infrared reflection film layer 501 is exemplified in FIG. 5 with the second adhesive layer 2014.
[0075] In this embodiment, by arranging the infrared reflection layer 501 in the glass assembly to reflect infrared rays, if the glass assembly is installed on a vehicle, the stability of the temperature inside the vehicle can be maintained. In addition, arranging the infrared reflection layer 501 between the first adhesive layer 2013 and the second glass piece 2012, or between the second adhesive layer 2014 and the second glass piece 2012, can slow down the aging speed of the adhesive layer and the light output layer 203 under the sunlight.
[0076] In an exemplary embodiment, as shown in FIG. 6, the glass assembly further comprises a dimming layer 601, which is arranged between the first adhesive layer 2013 and the second adhesive layer 2013 to adjust the visible light transmittance of the glass assembly.
[0077] The visible light transmittance of the glass assembly can be adjusted by the dimming layer 601, so that the glass assembly appears transparent or frosted, which can improve the driving experience if the glass assembly is installed on a vehicle.
[0078] Optionally, the dimming layer 601 comprises a first conductive layer, a dimming functional layer and a second conductive layer, and a groove is etched on the first conductive layer and / or the second conductive layer by laser, i.e. a partition etching line, the shape of the partition etching line determines the shape of the pattern, so that the on-off of the areas can be controlled by the ECU (Electronic Control Unit), and the light and dark state of different areas and patterns can be changed, further improving the intelligence of the vehicle.
[0079] In an exemplary embodiment, the present application also provides a vehicle comprising the glass assembly described in any one of the embodiments.
