[0029] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0031] It will be understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor without departing from the scope of this application. The first resistor and the second resistor are both resistors, but they are not the same resistor.

[0032] It will be understood that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0033] In the description of this application, it should be understood that "electrical connection" in this application can be understood as physical contact and electrical conduction between components; it can also be understood as a form in which different components in a circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals.

[0034] As used in this application, the term "and / or" includes any and all combinations of one or more of the associated listed items. When a statement such as "at least one of..." follows a list of elements, it modifies the entire list of elements, not the individual elements in the list.

[0035] It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0036] It should also be understood that when interpreting an element, even if not explicitly described, the element is interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately," "approximately," or "substantially" can mean within one or more standard deviations, and is not limited here.

[0037] As vehicles become increasingly intelligent, the glass they use is increasingly integrating more functions. Single-function glass products, such as luminous glass, dimming glass, and thermal insulation glass, are now also being introduced, along with composite glass products that combine multiple functions. However, when multiple functions are combined, sometimes two of them can interfere with each other. This doesn't guarantee that each function remains independent and unaffected by the others. Some of these interactions can be positive, while others can be detrimental.

[0038] In related technologies, glass products that combine luminous and thermal insulation functions, that is, glass products that combine the ambient luminous function of luminous glass with the low-emissivity coating function of thermal insulation glass, can be called glass assemblies. The low-emissivity film layer in this type of glass assembly must consider reducing both thermal radiation and reflection. However, since the main consideration when developing the low-emissivity film layer is reducing thermal radiation, and the anti-reflection function is superimposed on this reduction, the effects of visible light conduction and diffuse reflection on the glass substrate on the surface where the low-emissivity film layer is deposited are not considered. The visible light transmittance of the low-emissivity film layer is generally 65%. Based on the current actual combination effect, coating this low-emissivity film layer on glass has an adverse effect on the brightness and color of the final glass assembly. As shown in Table 1, compared with glass assemblies without low-emissivity film layers, this low-emissivity film layer will reduce the brightness of the glass assembly when it is illuminated, and will also cause color deviations.

[0039] Table 1 shows the Figure 1The glass component shown in the figure simulates the brightness values ​​at different positions before and after the low-emissivity film layer in the related technology is coated. The brightness values ​​of 9 positions on the same straight line in the glass component are simulated. The brightness value of the glass component when it is illuminated without the low-emissivity film layer is used as the standard brightness value, and the brightness value of the glass component when it is illuminated with the low-emissivity film layer is used as the true brightness value. The brightness difference calculation formula is used to calculate the brightness difference between the true brightness value and the standard brightness value at different positions. The unit of brightness value is: cd / m 2 .

[0040] Brightness difference = (standard brightness value - actual brightness value) / standard brightness value × 100%

[0041] Table 1

[0042]

[0043] Based on this, it is necessary to propose effective technical means to address the brightness attenuation and color deviation problems caused by low-emissivity coatings on glass components. The following detailed examples illustrate the technical solution of this application and how it solves the aforementioned technical problems. Furthermore, the following specific examples can be combined with one another, and the same or similar concepts or processes may not be described in detail in some examples.

[0044] In one embodiment, Figure 2 , a cross-sectional schematic diagram of a glass assembly is provided, the glass assembly includes a laminated glass 201, a low-emissivity film 202, and a light output layer 203. The laminated glass 201 includes a first glass 2011 and a second glass 2012 in a stacked arrangement; the low-emissivity film 202 is disposed on a side of the first glass 2011 away from the second glass 2012, and the light output layer 203 is disposed on the laminated glass 201. It should be noted that Figure 1 The glass components in Figure 2 The glass components shown are of the same construction.

[0045] Optionally, the laminated glass element 201 is a sunroof, front windshield, rear windshield, or side window. The laminated glass element 201 includes a first glass element 2011, a second glass element 2012, and a first adhesive layer 2013; the first adhesive layer 2013 is disposed between the first glass element 2011 and the second glass element 2012. The first glass element 2011 includes a first surface and a second surface, and the second glass element 2012 includes a third surface and a fourth surface. The first surface is distal to the third surface, the second surface is proximal to the third surface, the third surface is proximal to the second surface, and the fourth surface is distal to the second surface. When the laminated glass element 201 is installed in a vehicle, the first surface, the second surface, the third surface, and the fourth surface appear as viewed from the vehicle interior toward the exterior of the window. The material of the first adhesive layer 2013 can be PVB (Polyvinyl Butyral), which can bond the first glass piece 2011 and the second glass piece 2012 together through a lamination process to form a laminated glass piece 201, thereby effectively improving the strength and toughness of the laminated glass piece 201, and also improving the collision resistance and safety performance of the laminated glass piece 201.

[0046] The light output layer 203 can be a reflective sheet. There are various specific locations for the light output layer 203 on the laminated glass 201. The light output layer 203 can be located on the second surface of the first glass 2011, that is, between the first glass 2011 and the first adhesive layer 2013; on the first surface of the first glass 2011; or within the first glass. The specific location of the light output layer 203 on the laminated glass 201 is not limited herein. It should be noted that when the light output layer is located on the first surface of the first glass 2011, the low-emissivity film 202 is located on the side of the light output layer 203 away from the first glass 2011.

[0047] The orthographic projection of the light output layer 203 on the first glass member 2011 covers at least a portion of the first glass member 2011, that is, covers a portion or the entire area of ​​the first glass member 2011. Figure 2 In the example, the orthographic projection of the light output layer 203 on the first glass member 2011 covers a portion of the first glass member 2011, and the light output layer 203 is disposed on the second surface of the first glass member 2011. Figure 2 The light output layer 203 is indicated by a dotted line.

[0048] Regardless of where the light output layer 203 is positioned, its purpose is to direct light transmitted from the first glass member 2011 outward from the side of the first glass member 2011 facing away from the second glass member 2012, thereby achieving a luminous effect. The light transmitted from the first glass member 2011 can originate from the light guide assembly 204 and the light source 205. The light guide assembly 204 and the light source 205 can be positioned on the side of the low-emissivity film 202 facing away from the first glass member 2011, or on a side surface of the first glass member 2011 (a side surface refers to any surface of the first glass member 2011 that intersects the first and second surfaces).

[0049] In the following example, the light output layer 203 is disposed on the second surface of the first glass member 2011, and the light guide assembly 204 and the light source 205 are disposed on the side of the low-emissivity film layer 202 away from the first glass member 2011. The light emitting principle of the glass assembly is as follows:

[0050] Light guide assembly 204 directs light from light source 205 onto low-emissivity film 202. Low-emissivity film 202 refracts the light toward first glass element 2011, where it is then conducted through first glass element 2011. Light output layer 203 reflects light emitted from first glass element 2011 back to first glass element 2011, which then emits the light from the first surface of first glass element 2011, achieving a luminous effect for the glass element.

[0051] The low-emissivity film 202 has a visible light transmittance of 88% to 92%, reflecting infrared radiation. This effectively blocks the convection of infrared radiation inside and outside the housing, reducing heat transfer. For example, the visible light transmittance of the low-emissivity film 202 can be, but is not limited to, 88%, 88.5%, 89%, 89.5%, 90%, 90.5%, 91%, 91.5%, 92%, or a range consisting of any two of these values.

[0052] Through Table 2, Table 3, Table 4 and Figure 3 It can be clearly seen that the visible light transmittance of the low-emissivity film 202 is 88% to 92%, which can greatly improve the brightness of the glass component and reduce color deviation. The brightness of the glass component when it is illuminated is represented by the brightness value, and the color of the glass component when it is illuminated is represented by the color coordinates.

[0053] Table 2 shows the Figure 1 The following table compares the brightness values ​​at different positions of the glass assembly with the standard brightness value (the brightness value of the glass assembly without the low-emissivity film) when the visible light transmittance of the simulated low-emissivity film layer 202 is 65%, 75%, 88%, 91.5% and 92%, respectively.

[0054] Table 3 is a comparison table of color coordinates at different positions and standard color coordinates (color coordinates of glass components without low-emissivity film) when the visible light transmittance of the low-emissivity film 202 is 65%, 75%, 88%, 91.5% and 92%, respectively.

[0055] Table 4 is a comparison table of the average color coordinates and the standard color coordinates 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. The color coordinate difference between the average color coordinates and the standard color coordinates is calculated using the following color coordinate difference calculation formula.

[0056] Color coordinate difference = (standard color coordinate - color coordinate mean) / standard color coordinate × 100%

[0057] Figure 3 The figures are actual comparisons of glass components when the visible light transmittance of the low-emissivity film layer 202 is 65%, 75%, 88%, 91.5% and 92% respectively.

[0062] Table 4

[0063]

[0064] Based on this, the glass assembly includes a laminated glass element 201, a low-emissivity film layer 202, and a light output layer 203. The laminated glass element 201 includes a first glass element 2011 and a second glass element 2012. The low-emissivity film layer 202 is disposed on the side of the first glass element 2011 facing away from the second glass element 2012. The light output layer 203 is disposed on the laminated glass element 201 and is configured to direct light transmitted through the first glass element 2011 outward from the side of the first glass element 2011 facing away from the second glass element 2012. The low-emissivity film layer 202 has a visible light transmittance of 88% to 92%. Using a low-emissivity film layer with a visible light transmittance of 88% to 92% can improve the brightness of the glass assembly and reduce color deviation.

[0065] In an exemplary embodiment, the thickness of the low-emissivity film layer 202 is less than or equal to about 200 nm.

[0066] Low-emissivity film 202 is a composite film, consisting of multiple superimposed layers. Through multiple experiments, certain layers in conventional low-emissivity films that affect visible light were removed, resulting in a low-emissivity film 202 with a visible light transmittance of 88% to 92%. It should be noted that since conventional low-emissivity films have a variety of specific structures, the specific layers to be removed will vary for each conventional low-emissivity film. This can be determined through multiple experiments. Therefore, the specific structure of low-emissivity film 202 is not limited here.

[0067] Conventional low-emissivity films are generally thicker than about 210 nm. Multiple experiments have shown that to achieve a visible light transmittance of 88% to 92%, the thickness of low-emissivity film 202 is generally reduced by about 10 nm to 50 nm compared to conventional low-emissivity films, meaning that the thickness of low-emissivity film 202 is less than or equal to about 200 nm. Alternatively, the thickness of low-emissivity film 202 is less than or equal to about 190 nm; alternatively, the thickness of low-emissivity film 202 is less than or equal to about 190 nm and greater than or equal to about 160 nm.

[0068] In this embodiment, the thickness of the low-emissivity film layer 202 is less than or equal to 200 nm, so that the visible light transmittance is achieved at 88% to 92% while also reducing thermal radiation.

[0069] In an exemplary embodiment, the reflection color of the surface of the first glass member 2011 provided with the low-emissivity film layer 201 is, in the LAB color space, a color component L value of 28-38, a color component A value of -1-1, and a color component B value of -1-1.

[0070] Optimizing the reflected color of the low-emissivity film 201 and reducing its impact on light are crucial for resolving color deviations in glass components. Reflected color can be expressed as a LAB value. Optimizing the reflected color of the low-emissivity film 201 can involve optimizing the LAB value of the surface of the first glass element 2011 with the low-emissivity film 201 to the LAB value of the first glass element 2011 without the film 201.

[0071] Without the low-emissivity film 201, the first glass member 2011 has a neutral color. The LAB value corresponding to the neutral color is used as the standard LAB value. Table 5 compares the LAB values ​​of the surface of the first glass member 2011 with the low-emissivity film 201, when the visible light transmittance of the low-emissivity film 202 is 65%, 75%, 88%, 91.5%, and 92%, respectively.

[0072] Table 5

[0073]

[0074] Table 5 shows that three sets of LAB values ​​were measured for low-emissivity film 202 with varying visible light transmittances. In reality, there are many more sets of LAB values, which are not listed here. This is due to the instability of existing low-emissivity film production processes, which have stability tolerances of L = ±4, A = ±1, and B = ±1. Combining the LAB values ​​for low-emissivity films with varying visible light transmittances in Table 5 with existing low-emissivity film production processes, the LAB values ​​for the surface of the first glass element 2011 coated with the low-emissivity film 201 can range from 28 to 38 for L, from -1 to 1 for color component A, and from -1 to 1 for color component B.

[0075] In this embodiment, the reflected color of the surface of the first glass component provided with the low-emissivity film 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. These values ​​are close to the LAB values ​​of neutral colors, which can reduce color deviation when the glass component emits light.

[0076] In an exemplary embodiment, the first glass component 2011 is ultra-white glass, and ultra-white glass with a visible light transmittance of 88% to 93% is selected. That is, the visible light transmittance of the ultra-white glass can be, but is not limited to, 88%, 89%, 90%, 91%, 92%, 93% or a range consisting of any two of these values. This can further improve the brightness of the glass component when it is illuminated, and reduce the color deviation of the glass component when it is illuminated.

[0077] In an exemplary embodiment, the first adhesive layer 2013 can be made of a material having a visible light transmittance of 80% to 98%, such as light-colored PVB having a visible light transmittance of 80% to 98%. In other words, 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 consisting of any two of these values. The thickness of the first adhesive layer 2013 can be 0.38 mm or 0.76 mm.

[0078] Experiments have found that, under the same conditions, the brightness of the glass component when it is illuminated will also change accordingly when the visible light transmittance of the first adhesive layer 2013 is changed, as shown in Table 6. Table 6 is a comparison table of the brightness values ​​of the glass component when it is illuminated when the visible light transmittance of the first adhesive layer 2013 is 18%, 60%, 80%, 88%, and 98%. It can be seen that the higher the visible light transmittance of the first adhesive layer 2013, the higher the brightness value of the glass component when it is illuminated. Based on the brightness value comparison in Table 6, the first adhesive layer 2013 with a visible light transmittance of 80% to 98% is selected. It should be noted that the measurement position of the brightness of the glass component in Table 6 is different from the Figure 1 Same location as shown.

[0079] Table 6

[0080]

[0081] In an exemplary embodiment, Figure 4 As shown, a second bonding layer 2014 is provided between the second glass member 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.

[0082] The preset visible light transmittance can be the visible light transmittance of glass required by glass design specifications. The second adhesive layer 2014 can be made of a material with a visible light transmittance lower than that of the first adhesive layer 2013. Optionally, a material with a visible light transmittance greater than or equal to 60% and less than 80% can be used, such as dark PVB with a visible light transmittance of 60% to 80%. In other words, the visible light transmittance of the second adhesive 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 consisting of any two of these values.

[0083] The thickness of the second adhesive layer 2014 can be 0.38 mm or 0.76 mm. Preferably, when the second adhesive layer 2014 is provided between the second glass member 2012 and the first adhesive layer 2013, the thickness of the second adhesive layer 2014 and the first adhesive layer 2013 are both 0.38 mm.

[0084] In this embodiment, the glass design specifications require that the visible light transmittance of the glass be within different ranges for different uses of the glass. In other words, the designed glass must meet optical specifications. For example, for glass installed on a vehicle, the glass design specifications require that the visible light transmittance of the glass be between 50% and 90%. Therefore, if the first glass piece 2011, the first adhesive layer 2013, and the low-emissivity film layer 202 in the glass assembly all have high transmittance, a second adhesive layer 2014 must be provided to ensure that the glass assembly meets the optical specifications.

[0085] In an exemplary embodiment, Figure 5 As shown, the glass assembly further includes an infrared reflective film layer 501 , which is disposed between the first adhesive layer 2013 and the second glass member 2012 to reflect infrared rays.

[0086] Optional, based on Figure 2 The glass assembly shown in FIG. 2 is a case where there is no second adhesive layer 2014 , and the infrared reflective film layer 501 is disposed between the first adhesive layer 2013 and the second glass member 2012 ; Figure 4 In the glass assembly shown, that is, in the case where the second bonding layer 2014 is present, the infrared reflective film layer 501 is disposed between the second bonding layer 2014 and the second glass member 2012 . Figure 5 The second adhesive layer 2014 is used as an example to illustrate the location of the infrared reflective film layer 501 .

[0087] In this embodiment, an infrared reflective layer 501 is provided within the glass assembly to reflect infrared rays. This allows the glass assembly to maintain a stable temperature within a vehicle when installed. Furthermore, placing the infrared reflective layer 501 between the first adhesive layer 2013 and the second glass member 2012, or between the second adhesive layer 2014 and the second glass member 2012, can reduce the rate of degradation of the adhesive layer and the light output layer 203 caused by sunlight.

[0088] In an exemplary embodiment, Figure 6 As shown, the glass assembly further includes a dimming layer 601 , which is disposed between the first bonding layer 2013 and the second bonding layer 2013 to adjust the visible light transmittance of the glass assembly.

[0089] The visible light transmittance of the glass component can be adjusted by the dimming layer 601, so that the glass component is transparent or frosted. In this way, if the glass component is installed in a vehicle, the driving experience can be improved.

[0090] Optionally, the dimming layer 601 includes a first conductive layer, a dimming functional layer and a second conductive layer. Grooves, that is, partition etching lines, are etched on the first conductive layer and / or the second conductive layer by laser. The shape of the partition etching lines correspondingly determines the shape of the pattern. In this way, by controlling the power on and off between areas through the ECU (Electronic Control Unit), the light and dark states of different areas and patterns can be changed, thereby further improving the intelligence of the vehicle.

[0091] In one embodiment, the present application further provides a vehicle comprising the glass assembly described in any one of the glass assembly embodiments.

[0092] Among them, the means of transport may include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, the means of transport may be a vehicle, which is a vehicle in a broad sense and may be a means of transport (such as a commercial vehicle, a passenger car, a motorcycle, a flying car, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), agricultural equipment (such as a lawn mower, a harvester, etc.), amusement equipment, a toy vehicle, etc. The embodiments of the present application do not specifically limit the type of vehicle. For another example, the means of transport may be a vehicle such as an airplane or a ship.
