DETAILED DESCRIPTION
[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0027] In the description of the present application, it should be understood that the terms "thickness", "front", "rear", etc., indicating orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0029] In this application, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" 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 mechanical connection or an electrical 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, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] In the present application, unless otherwise clearly specified and limited, a first feature "on" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature "on" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.
[0031] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.
[0032] In the related art, one way to achieve the glass assembly ambient light effect is to first connect two glass layers together through an adhesive layer, and use one of the glass layers as a waveguide medium layer of an optical waveguide. Then, a light source is arranged on the glass assembly so that the light emitted by the light source is incident on the inside of the waveguide medium layer. Then, the light is propagated in the waveguide medium layer, and then emitted through a light extraction structure attached to the surface of the waveguide medium layer, ultimately achieving the interior lighting of the vehicle and the ambient light effect inside the vehicle.
[0033] In order to ensure a certain degree of privacy for the glass assembly, a dark-colored adhesive layer such as gray or dark gray is used when bonding the waveguide dielectric layer to other film layers, so that the glass assembly as a whole appears to have low transparency. However, when light propagates in the waveguide dielectric layer, it is absorbed by the dark-colored adhesive layer, resulting in light loss and reduced light utilization efficiency, ultimately resulting in insufficient emitted light, poor lighting and ambient light effects, and failure to meet expectations.
[0034] Based on the above problems, the present application proposes a glass assembly and a vehicle to improve the efficiency of light utilization, thereby improving the lighting and atmosphere lighting effects of the glass assembly.
[0035] The embodiment of the first aspect of the present application provides a glass assembly 100. Figure 1As shown, the glass assembly 100 includes a light source 110, a first glass layer 120, a second glass layer 130, and a first adhesive layer 140. The light source 110 is used to emit visible light, and the first glass layer 120 is configured to allow the visible light to be guided inside the first glass layer 120. The second glass layer 130 is located on one side of the first glass layer 120. The first adhesive layer 140 is located between the first glass layer 120 and the second glass layer 130, and the first adhesive layer 140 is bonded to a surface of the first glass layer 120 close to the second glass layer 130, and the visible light transmittance of the first adhesive layer 140 is greater than or equal to 40%.
[0036] The glass assembly 100 of the present application includes a light source 110, a first glass layer 120, a second glass layer 130 and a first adhesive layer 140. The glass assembly 100 can be used, for example, as a sunroof, side window, front windshield, rear windshield, etc. of a vehicle such as an electric vehicle or a fuel vehicle. The light source 110 can be, for example, an LED lamp bead, an LED light bar, etc. The first glass layer 120 is an optical waveguide, and the light emitted by the light source 110 can enter the first glass layer 120, so that an optical waveguide occurs in the first glass layer 120, and finally emitted from the first glass layer 120 to achieve the lighting and atmosphere light effects of the glass assembly 100. The second glass layer 130 is located on one side of the first glass layer 120. That is, the glass assembly 100 of the present application is a double-layer glass structure, which is conducive to reducing the weight of the glass assembly 100 and reducing its thickness. Among them, the first glass layer 120 can be a side close to the interior space of the vehicle, and the second glass layer 130 can be a side away from the interior space of the vehicle. The first glass layer 120 and the second glass layer 130 may be made of inorganic glass or organic glass (resin).
[0037] In the related art, the first adhesive layer uses a dark color such as gray, dark gray and other adhesive layers with low visible light transmittance, so that the light is absorbed by the dark color of the adhesive layer when it is transmitted in the first glass layer, thereby reducing the amount of light coming out of the first glass layer and reducing the light utilization efficiency.
[0038] In the present application, the visible light transmittance of the first adhesive layer 140 is greater than or equal to 40%. Visible light transmittance refers to the ratio of the radiant energy of light passing through an object to the total radiant energy projected onto the object. The first adhesive layer 140 can be, for example, highly transparent adhesive materials such as polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), and thermoplastic polyurethane (TPU). The high visible light transmittance of the first adhesive layer 140 reduces the probability that the light in the first glass layer 120 is absorbed by the first adhesive layer 140, which is beneficial to improve the light utilization efficiency of the first glass layer 120, and further improve the lighting and atmosphere lighting effects of the glass assembly 100.
[0039] In some embodiments, Figure 1As shown, the glass assembly 100 further includes a light extraction structure 150, which is disposed on at least one side surface of the first glass layer 120 in the thickness direction thereof. In this embodiment, the light extraction structure 150 of the glass assembly 100 is used to extract the light transmitted in the first glass layer 120 and emit the extracted light from the first glass layer 120, so that the light is reflected, scattered or diffused, thereby achieving the lighting and atmosphere light effects of the glass assembly 100. The light extraction structure 150 can be, for example, a film layer structure such as a coating layer or a printing layer, or can be a structure formed on the glass surface by sandblasting, engraving, screen printing, etching, or the like. Figure 2 As shown, the light extraction structure 150 may include a plurality of light extraction units 151, and the plurality of light extraction units 151 form a pattern of a certain shape, so that the lighting and ambient light of the glass assembly 100 also present a pattern display. In this way, it is helpful to further improve the lighting and ambient light effects.
[0040] like Figure 2 As shown, the light extraction structure 150 can be disposed on a surface of the first glass layer 120 facing away from the second glass layer 130; or Figure 3 As shown, the light extraction structure 150 can be disposed on a side surface of the first glass layer 120 close to the second glass layer 130; or Figure 1 As shown, the light extraction structure 150 is disposed on both a side surface of the first glass layer 120 facing away from the second glass layer 130 and a side surface of the first glass layer 120 close to the second glass layer 130 .
[0041] In some embodiments, the visible light transmittance TL of the first adhesive layer 140 is greater than or equal to 70%. After in-depth research, the applicant found that there is a positive correlation between the visible light transmittance TL of the first adhesive layer 140 and the light utilization efficiency η emitted after the light passes through the first glass layer 120. The light utilization efficiency η is measured by measuring the total value of the luminous flux entering the first glass layer 120 and the luminous flux value emitted by the light extraction structure 150, and then calculating the ratio of the emitted luminous flux value to the total value of the luminous flux entering the first glass layer 120 to obtain the light utilization efficiency η. The following Table 1 shows the relationship between the change in the visible light transmittance TL of the first adhesive layer 140 and the light utilization efficiency η of the first glass layer when the thickness of the first adhesive layer 140 is 0.76 mm and the difference between the refractive index of the first adhesive layer 140 and the refractive index of the first glass layer 120 is 0.03:
[0042] Table 1 Comparison of the relationship between the visible light transmittance TL of the first adhesive layer and the light utilization efficiency η of the first glass layer
[0043]
[0044] It can be seen from the above table that the higher the visible light transmittance TL of the first adhesive layer 140, the higher the light utilization efficiency η of the first glass layer 120. When the visible light transmittance TL of the first adhesive layer 140 is greater than or equal to 40%, the light utilization efficiency η is greater than 90%. In this way, it is beneficial to improve the lighting and atmosphere lighting effects of the glass assembly 100. When the visible light transmittance TL of the first adhesive layer 140 is greater than or equal to 70%, the light utilization efficiency η is close to 100%. Therefore, in this embodiment, the visible light transmittance TL of the first adhesive layer 140 is set to be greater than or equal to 70%, which is beneficial to further improve the light utilization efficiency of the first glass layer 120, and further help to further improve the lighting and atmosphere lighting effects of the glass assembly 100.
[0045] In some embodiments, the thickness T of the first adhesive layer 140 is greater than or equal to 0.3 mm. After in-depth research, the applicant found that there is also a positive correlation between the thickness T of the first adhesive layer 140 and the light utilization efficiency η emitted after the light passes through the first glass layer 120. The following Table 2 shows the relationship between the change in the thickness T of the first adhesive layer 140 and the light utilization efficiency η of the first glass layer 120 when the visible light transmittance TL of the first adhesive layer 140 is 85% and the difference between the refractive index of the first adhesive layer 140 and the refractive index of the first glass layer 120 is 0.03:
[0046] Table 2 Comparison of the relationship between the thickness T of the first adhesive layer and the light utilization efficiency η of the first glass layer
[0047]
[0048] As can be seen from the above table, the thicker the thickness T of the first adhesive layer 140 is, the higher the light utilization efficiency η of the first glass layer 120 is. When the thickness T of the first adhesive layer 140 is greater than or equal to 0.3 mm, the light utilization efficiency η is greater than 80%. This is conducive to improving the lighting and atmosphere lighting effects of the glass assembly 100.
[0049] Preferably, the thickness T of the first adhesive layer 140 is greater than 0.6 mm, for example, 0.7 mm, 0.8 mm, etc. At this time, the light utilization efficiency η is close to 100%. In this way, it is beneficial to further improve the light utilization efficiency of the first glass layer 120, and further improve the lighting and atmosphere lighting effects of the glass assembly 100.
[0050] In some embodiments, the refractive index of the first glass layer 120 is greater than the refractive index of the first adhesive layer 140 , and the difference between the refractive index of the first glass layer 120 and the refractive index of the first adhesive layer 140 is greater than or equal to 0.02 and less than or equal to 0.08.
[0051] In this embodiment, one side of the first glass layer 120 is air, and the other side is the first adhesive layer 140. The refractive index of the air and the first adhesive layer 140 are both smaller than the refractive index of the first glass layer 120, so that the first glass layer 120 can be used as an optical waveguide for light to be guided therein. Further, the difference Δn between the refractive index of the first glass layer 120 and the refractive index of the first adhesive layer 140 is greater than or equal to 0.02 and less than or equal to 0.08. Setting the difference Δn between the refractive indices of the two to be greater than or equal to 0.02 and less than or equal to 0.08 can ensure that the first glass layer 120 has a light transmission function on the one hand, and on the other hand, the difference in the refractive index of the two is not too large, so that the glass assembly 100 can maintain the corresponding optical performance.
[0052] In addition, the applicant has found through in-depth research that when the difference Δn between the refractive index of the first glass layer 120 and the refractive index of the first adhesive layer 140 is greater than or equal to 0.02 and less than or equal to 0.08, there is also a positive correlation between the difference Δn and the light utilization efficiency η of the first glass layer 120. The following Table 3 shows the relationship between the change in the difference Δn between the refractive index of the first glass layer 120 and the refractive index of the first adhesive layer 140 and the light utilization efficiency η of the first glass layer 120 when the visible light transmittance TL of the first adhesive layer 140 is 85% and the thickness T of the first adhesive layer 140 is 0.76 mm:
[0053] Table 3 Comparison of the difference Δn and the light utilization efficiency η of the first glass layer
[0054]
[0055] As can be seen from the above table, when the difference Δn between the refractive index of the first glass layer 120 and the refractive index of the first adhesive layer 140 is greater than or equal to 0.02 and less than or equal to 0.08, the light utilization efficiency η of the first glass layer 120 is greater than 80%, which is beneficial to improving the lighting and ambient light effects of the glass assembly 100. In addition, the greater the difference Δn, the higher the light utilization efficiency η of the first glass layer 120. Therefore, it is beneficial to further improve the lighting and ambient light effects of the glass assembly 100.
[0056] In some embodiments, Figure 1 As shown, the glass assembly 100 further includes a second adhesive layer 160 located between the first adhesive layer 140 and the second glass layer 130 , the second adhesive layer 160 is bonded to a surface of the first adhesive layer 140 close to the second glass layer 130 , and a visible light transmittance of the second adhesive layer 160 is less than or equal to 30%.
[0057] In this embodiment, the glass assembly 100 further includes a second adhesive layer 160, and the second adhesive layer 160 is bonded to the surface of one side of the first adhesive layer 140 close to the second glass layer 130. That is, the second adhesive layer 160 and the first adhesive layer 140 are stacked. The glass assembly 100 needs to meet the privacy requirements. If the transmittance of the glass assembly 100 is too high, the privacy of the interior space of the vehicle will be poor. Therefore, there are certain requirements for the overall transmittance of the glass assembly 100. For example, it is required that the overall transmittance of the glass assembly 100 is less than or equal to 20%, and greater than or equal to 10%, or less than or equal to 15%, and greater than or equal to 5%, or less than or equal to 25%, and greater than or equal to 5%, etc. are in a low transmittance range. Therefore, in this embodiment, the glass assembly 100 further includes a second adhesive layer 160 stacked with the first adhesive layer 140, and the visible light transmittance of the second adhesive layer 160 is less than or equal to 30%, so that the overall transmittance of the first adhesive layer 140 and the second adhesive layer 160 will not be too high. In this way, when adjusting the overall transmittance of the glass assembly 100 , the selectable range of transmittances of other film layers is wider, thereby facilitating the convenience of manufacturing 100 .
[0058] In some embodiments, the thickness of the second adhesive layer 160 is greater than or equal to 0.3 mm. In this way, firstly, there is a certain relationship between the thickness and the transmittance, and setting it to be greater than or equal to 0.3 mm is conducive to accurately controlling the visible light transmittance of the second adhesive layer 160. Secondly, it is conducive to improving the bonding effect of the second adhesive layer 160.
[0059] Alternatively, if Figure 4 As shown, in some embodiments, the second glass layer 130 of the glass assembly 100 is sequentially combined with the first glass layer 120 through the second adhesive layer 160 and the first adhesive layer 140. That is, only the first adhesive layer 140 and the second adhesive layer 160 are disposed between the first glass layer 120 and the second glass layer 130. In this way, on the one hand, it is helpful to improve the light utilization efficiency, thereby improving the lighting and atmosphere light effects of the glass assembly 100, and on the other hand, it is also helpful to achieve the lightness and thinness requirements of the glass assembly 100.
[0060] Optionally, in some embodiments, Figure 1 , Figure 5 As shown, the glass assembly 100 further includes a functional layer 170 and a third adhesive layer 180 . One side of the functional layer 170 is connected to the second glass layer 130 via the third adhesive layer 180 , and the other side of the functional layer 170 is connected to the first glass layer 120 via the second adhesive layer 160 and the first adhesive layer 140 .
[0061] In this embodiment, the glass assembly 100 further includes a functional layer 170 and a third adhesive layer 180. The functional layer may be, for example, a photovoltaic cell layer, a dimming layer, a display functional layer, and the like. The photovoltaic cell layer can realize the solar power generation function of the glass assembly 100, the dimming layer can realize the adjustment of the transmittance of the glass assembly 100 as a whole, and the display functional layer can realize the screen display function of the glass assembly 100. One side of the functional layer 170 is connected to the second glass layer 130 through the third adhesive layer 180, and the other side is connected to the first glass layer 120 through the second adhesive layer 160 and the first adhesive layer 140. In this way, the fixed installation of the functional layer 170 is realized. Optionally, the transmittance of the third adhesive layer 180 can be flexibly set according to actual needs so that the transmittance of the glass assembly 100 as a whole meets the requirements.
[0062] In some embodiments, Figure 1 As shown, the orthographic projection of the first glass layer 120 on the first adhesive layer 140 is located within the orthographic projection of the second glass layer 130 on the first adhesive layer 140. The light source 110 is arranged on the side of the first glass layer 120 and is fixedly connected to the side surface of the second glass layer 130 close to the first glass layer 120, so that the light source 110 and the side wall of the first glass layer 120 are arranged opposite to each other. In this embodiment, the area of the first glass layer 120 is smaller than the area of the second glass layer 130, so that the second glass layer 130 reserves an installation space for the light source 110. The light source 110 is arranged on the side of the first glass layer 120 and is fixedly connected to the side surface of the second glass layer 130 close to the first glass layer 120. In this way, the light emitted by the light source 110 can be incident into the first glass layer from the side end surface of the first glass layer 120, without the need to set up a related light guide 190.
[0063] In some embodiments, Figure 4 , Figure 5 As shown, the glass assembly 100 also includes a light guide 190, and the light guide 190 includes a light incident surface 191 and a light emitting surface 192. The light incident surface 191 is arranged opposite to the light source 110, and the light emitting surface 192 is in contact with the surface of the first glass layer 120 that is away from the second glass layer 130. In this embodiment, the glass assembly 100 is provided with a light guide 190. The function of the light guide 190 is to direct the light emitted by the light source 110 into the first glass layer 120 at a certain angle, so that the light is optically waveguided in the first glass layer 120. The light guide 190 can be, for example, a glass block, a transparent optical adhesive block, etc. Preferably, the light guide 190 can be made of the same material as the first glass layer 120 or a material with similar optical properties such as refractive index, visible light transmittance and haze, so that the light guide 190 and the first glass layer 120 have the same or equivalent optical properties, which is beneficial to improve the light guiding performance of the light guide 190. Figure 5In the figure, the light incident surface 191 and the light emitting surface 192 of the light guide 190 form an angle of 90°, but this does not limit the angle between the light incident surface 191 and the light emitting surface 192 of the light guide 190. In practice, the light incident surface 191 and the light emitting surface 192 of the light guide 190 can be flexibly set according to the refractive index of the light guide 190, the incident angle of the light source 110, etc.
[0064] The embodiment of the second aspect of the present application proposes a vehicle, including the glass assembly 100 described in the first aspect. The vehicle can be, for example, an electric vehicle, a fuel vehicle, etc. In the present application, the visible light transmittance of the first adhesive layer 140 is greater than or equal to 40%, so that the probability of the light in the first glass layer 120 being absorbed by the first adhesive layer 140 is reduced, which is conducive to improving the light utilization efficiency of the first glass layer 120, and then to improving the lighting and atmosphere lighting effects of the glass assembly 100 and the vehicle. In the second aspect, the visible light transmittance of the second adhesive layer 160 is set to be less than or equal to 30%. In this way, the overall transmittance of the first adhesive layer 140 and the second adhesive layer 160 will not be too high. When adjusting the overall transmittance of the glass assembly 100, the selectable range of the transmittance of other film layers is larger, which is also conducive to improving the convenience of preparing the glass assembly 100 while ensuring the privacy of the glass assembly 100, and reducing the production cost.
[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0066] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
