[0001] This disclosure claims priority to Chinese Patent Application No. 202411837908.8, filed on December 13, 2024, entitled "Laminated Glass and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of glass technology, specifically relating to laminated glass and vehicles. Background Technology

[0003] As users have increasingly higher requirements for vehicle glass, optical element layers are often added to laminated glass to create glass with dimming capabilities. To seal and protect the optical element layer, a sealing adhesive is applied around it. However, the sealing adhesive cannot match the color of the optical element layer in either the dark or light state, causing the area between the optical element layer and the sealing adhesive to be exposed in the user's field of vision. This abrupt color transition reduces the appearance of the laminated glass and diminishes the user experience. Summary of the Invention

[0004] In view of this, the first aspect of this application provides a laminated glass, the laminated glass including a first glass plate, an optical element layer, a transition layer and a second glass plate, the first glass plate, the optical element layer and the second glass plate being stacked sequentially, the transition layer being disposed in the same layer as the optical element layer and disposed on at least one periphery of the optical element layer, the laminated glass having an optical functional area formed by the optical element layer and a transition area formed by the transition layer.

[0010] The transition region reflects visible light with reflection values ​​Lab1: reflection L1, reflection a1, and reflection b1; the optical functional region reflects visible light with reflection values ​​Lab2: reflection L2, reflection a2, and reflection b2; and the laminated glass satisfies the following conditions: △reflection E≤3.5.

[0011] The material of the transition layer is selected from at least one of photochromic materials, thermochromic materials, and pressure-sensitive materials.

[0015] The laminated glass further includes a first adhesive layer and a second adhesive layer. The first glass plate, the first adhesive layer, the optical element layer, the second adhesive layer, and the second glass plate are stacked sequentially. The transition layer is disposed on the same layer as the optical element layer.

[0016] The first adhesive layer includes a first transition portion located in the transition region, and the second adhesive layer includes a second transition portion located in the transition region. The transition layer is disposed between the first transition portion and the second transition portion. Under different preset conditions, the first transition portion and the second transition portion have different visible light transmittance and different colors.

[0017] The laminated glass further includes a sensor controller electrically connected to the optical element layer, and the sensor controller is disposed in the first transition section or the second transition section.

Detailed Implementation

[0027] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0028] In view of this, in order to solve the above problems, please refer to Figures 1-4. This embodiment provides a laminated glass 1, which includes a first glass plate 10, an optical element layer 12, a transition layer 13, and a second glass plate 15. The first glass plate 10, the optical element layer 12, and the second glass plate 15 are stacked sequentially. The transition layer 13 is disposed on the same layer as the optical element layer 12 and is located on at least one circumference of the optical element layer 12. The laminated glass 1 has an optical functional area 121 formed by the optical element layer 12 and a transition area 131 formed by the transition layer 13.

[0029] Under different preset conditions, the transition layer 13 has different visible light transmittance and different colors; under different voltage values, the optical element layer 12 has different visible light transmittance and different colors.

[0030] When the laminated glass 1 is installed on a vehicle, it can serve as a windshield, a rear windshield, a side window, a corner window, or a sunroof, thus providing the vehicle with more display application scenarios.

[0031] Specifically, the first glass plate 10 serves as the outer glass plate of the laminated glass 1. The first glass plate 10 has a first surface and a second surface. The first surface is away from the optical element layer 12 and in contact with the external environment of the vehicle, while the second surface is close to the optical element layer 12. The second glass plate 15 serves as the inner glass plate of the laminated glass 1. The second glass plate 15 has a third surface and a fourth surface. The third surface is close to the optical element layer 12, while the fourth surface is away from the optical element layer 12 and in contact with the internal environment of the vehicle. The optical element layer 12 is disposed between the second surface and the third surface, and the transition layer 13 is disposed between the second surface and the third surface.

[0032] Furthermore, the laminated glass 1 also includes a first adhesive layer 11 and a second adhesive layer 14. The first glass plate 10, the first adhesive layer 11, the optical element layer 12, the second adhesive layer 14, and the second glass plate 15 are stacked sequentially, and the transition layer 13 is disposed on the same layer as the optical element layer 12.

[0033] The first surface faces away from the first adhesive layer 11, and the second surface is connected to the first adhesive layer 11. The optical element layer 12 is disposed between the first adhesive layer 11 and the second adhesive layer 14, and the transition layer 13 is disposed between the first adhesive layer 11 and the second adhesive layer 14. The third surface is connected to the second adhesive layer 14, and the fourth surface faces away from the second adhesive layer 14. The first adhesive layer 11 bonds the first glass plate 10 to the optical element layer 12, and also bonds the first glass plate 10 to the transition layer 13. The second adhesive layer 14 bonds the second glass plate 15 to the optical element layer 12, and also bonds the second glass plate 15 to the transition layer 13.

[0034] The outer glass plate has a thickness of 0.7mm to 4.0mm, and the visible light transmittance of the first glass plate 10 is ≥70%, meaning the visible light transmittance of the outer glass plate is greater than or equal to 70%. The outer glass plate is transparent glass, and the total iron content (calculated as Fe2O3) of the transparent glass is less than or equal to 0.1%, even less than or equal to 0.05%, and further less than or equal to 0.01%. The visible light transmittance of the transparent glass is 80% to 95%. For example, the outer glass plate can be 2.1mm thick transparent glass with a visible light transmittance of 89%. The thickness of the outer glass plate is preferably 1.6mm to 3.5mm.

[0035] The thickness of the inner glass plate is 0.7mm to 4.0mm, and the visible light transmittance of the second glass plate 15 is ≥70%, that is, the visible light transmittance of the inner glass plate is greater than or equal to 70%. The inner glass plate is transparent glass or colored glass. The total iron content (calculated as Fe2O3) of the transparent glass is less than or equal to 0.1%, even less than or equal to 0.05%, and further less than or equal to 0.01%, and the visible light transmittance of the transparent glass is 80% to 95%. The total iron content (calculated as Fe2O3) of the colored glass is 0.1% to 0.8%, preferably 0.1% to 0.5%, and the visible light transmittance of the colored glass is 70% to 90%. For example, the inner glass plate can be 2.1mm thick transparent glass with a visible light transmittance of 89%, or 1.6mm thick green glass with a visible light transmittance of 83%, or 2.1mm thick green glass with a visible light transmittance of 80%.

[0036] Both the first adhesive layer 11 and the second adhesive layer 14 can be transparent or colored thermoplastic polymer films, and the thickness of the first adhesive layer 11 and the second adhesive layer 14 is 0.38 mm to 2.28 mm. For example, the thickness of the first adhesive layer 11 and the second adhesive layer 14 can be, but is not limited to, 0.38 mm, 0.76 mm, 1.14 mm, 1.52 mm, 1.9 mm, 2.28 mm, or other values ​​between 0.38 mm and 2.28 mm. The material of the thermoplastic polymer film can be selected from at least one of polyvinyl butyral (PVB), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), and ionic polymer (SGP). Optionally, the visible light transmittance of the first adhesive layer 11 and the second adhesive layer 14 is ≥80%. When the first adhesive layer 11 and the second adhesive layer 14 are transparent thermoplastic polymers, the visible light transmittance of the transparent thermoplastic polymer is greater than or equal to 80%. For example, the visible light transmittance of the first adhesive layer 11 and the second adhesive layer 14 can be, but is not limited to, 80%, 85%, 90%, or 95%. When the first adhesive layer 11 and the second adhesive layer 14 are colored thermoplastic polymer films, the visible light transmittance of the colored thermoplastic polymer film is greater than or equal to 70%. For example, the visible light transmittance of the first adhesive layer 11 and the second adhesive layer 14 can be, but is not limited to, 70%, 75%, 80%, 85%, or 90%. The colored thermoplastic polymer film can be a gray thermoplastic polymer film, a green thermoplastic polymer film, or a blue thermoplastic polymer film. Exemplarily, the first adhesive layer 11 and the second adhesive layer 14 can be a single-layer structure or a multi-layer structure. Examples of multi-layer structures include double-layer structures, triple-layer structures, quadruple-layer structures, and five-layer structures. The first adhesive layer 11 and the second adhesive layer 14 may also have other functions, such as adding infrared absorbers to provide sun protection or heat insulation, or adding ultraviolet absorbers to provide ultraviolet protection, or having at least one layer of the multilayer structure with a higher plasticizer content to provide sound insulation.

[0037] The optical element layer 12 can also be understood as a dimming layer, possessing dimming functionality. The optical element layer 12 can be a polymer-dispersed liquid crystal film (PDLC), a suspended particle film (SPD), an electrochromic film (EC), a dye-based liquid crystal film (LC), etc. Preferably, the optical element layer 12 can be a dye-based liquid crystal (LC) containing a transparent sealant; that is, the optical element layer 12 can be a dye-based liquid crystal film (LC). The minimum visible light transmittance of the optical element layer 12 is less than or equal to 3%, for example, 3%, 2%, 1%, 0.5%, or 0%. Furthermore, the maximum visible light transmittance of the optical element layer 12 can be set as needed, for example, 10%, 20%, 30%, 50%, 70%, or 80%. Specifically, for example, the visible light transmittance of the optical element layer 12 can be adjusted between 0% and 20%, between 0.5% and 50%, or between 0% and 70%, etc.

[0038] When the optical element layer 12 is powered on, the optical element layer 12 exhibits different visible light transmittance and colors depending on the voltage applied to it, in order to meet the requirements of visible light transmittance and color in various scenarios. For example, when black border display is required, the optical element layer 12 is in an opaque state (visible light transmittance less than or equal to 3%, or even 0%), improving the contrast between the displayed image and the background. When no display is required, the optical element layer 12 is in a transparent state (visible light transmittance greater than or equal to 70%), achieving greater transparency in the laminated glass 1.

[0039] Under different preset conditions, the transition layer 13 has different visible light transmittance and different colors to match the visible light transmittance and color of the optical element layer 12. Specifically, the material of the transition layer 13 is selected from at least one of photochromic materials, thermochromic materials, and pressure-sensitive materials. For example, when the material of the transition layer 13 is selected as a photochromic material, the transition layer 13 has different visible light transmittance and different colors as the amount of irradiation received by the transition layer 13 changes. As another example, when the material of the transition layer 13 is selected as a thermochromic material, the transition layer 13 has different visible light transmittance and different colors as the temperature value of the transition layer 13 changes. Yet another example, when the material of the transition layer 13 is selected as a pressure-sensitive material, the transition layer 13 has different visible light transmittance and different colors as the pressure value applied to the transition layer 13 changes. In addition, the transition layer 13 is also used to fill the area of ​​the optical element layer 12 that is smaller than the laminated glass 1.

[0040] The transition layer 13 and the optical element layer 12 are disposed on the same layer, which can also be understood as the transition layer 13 and the optical element layer 12 being located approximately in the same structural layer. The thickness of the optical element layer 12 is equal to the thickness of the transition layer 13; or, the thickness of the optical element layer 12 is greater than the thickness of the transition layer 13; or, the thickness of the optical element layer 12 is less than the thickness of the transition layer 13. This embodiment does not limit this. Preferably, the thickness of the optical element layer 12 is equal to the thickness of the transition layer 13.

[0041] In summary, the laminated glass 1 provided in this embodiment, by providing a transition layer 13 with different visible light transmittance and different colors, allows the transition layer 13 to have a visible light transmittance and color similar to or the same as the optical element layer 12, thus achieving a natural connection between the transition layer 13 and the optical element layer 12. This improves the appearance performance of the laminated glass 1, enhances the user experience, and solves the problem of uneven transition between the transition layer 13 and the optical element layer 12. Furthermore, the black edge printing on the laminated glass 1 using related technologies can be omitted, reducing manufacturing costs and simplifying manufacturing processes.

[0042] In one embodiment, the transition region 131 has a minimum visible light transmittance TL. 1min The optical functional region 121 has a minimum visible light transmittance TL. 2min The laminated glass 1 satisfies the following condition: |TL 1min -TL 2min |=X%, 0≤X≤0.5.

[0043] TL 1min with TL 2min The absolute value of the difference is ≤0.5%, specifically, it can be 0.5%, 0.4%, 0.3%, 0.2%, 0.1%, or 0, etc., preferably 0≤X≤0.3; this embodiment limits TL. 1min with TL 2min The absolute value of the difference makes the minimum visible light transmittance of the transition layer 13 and the optical element layer 12 similar or equal, thereby ensuring that the transition layer 13 can have a visible light transmittance similar or the same as that of the optical element layer 12. When the user observes the laminated glass 1 with their eyes, the change between the transition layer 13 and the optical element is almost imperceptible, which better realizes the natural connection between the transition layer 13 and the optical element layer 12, further improving the appearance performance of the laminated glass 1 and further improving the user experience.

[0044] In the relevant technology, the sealant cannot adjust the visible light transmittance. The visible light transmittance of the sealant is 80%. The absolute value of the difference between the minimum value of the visible light transmittance of the sealant and the optical functional area 121 is 78.2, which is much greater than 0.5, resulting in an abrupt transition between the optical element layer 12 and the sealant.

[0045] In one embodiment, the preset conditions include a first preset value and a second preset value. When the value changes from the first preset value to the second preset value, the transition region 131 has a visible light transmittance change value ΔTL1. When the value changes from the first voltage value to the second voltage value, the optical functional region 121 has a visible light transmittance change value ΔTL2. The laminated glass 1 satisfies the following condition: |ΔTL1-ΔTL2|=Y%, 0≤Y≤3.

[0046] For example, if the first preset value is 0Wh of solar irradiance and the second preset value is 7.22Wh of solar irradiance, when transitioning from the first preset value to the second preset value, the transition region 131 has a visible light transmittance change value ΔTL1 of 32.1%; if the first voltage value is 0V and the second voltage value is 6.6V, the optical functional region 121 has a visible light transmittance change value ΔTL2 of 35%. ΔTL1 and TL... 2min The absolute value of the difference, ΔTL2, is 2.9%, which is less than 3%.

[0047] Specifically, the relationship between solar irradiance and the visible light transmittance TL1 of the transition zone 131 is determined by the photochromic material itself. Under a certain irradiance, the photochromic material has its corresponding TL1 value. Combining |ΔTL1-ΔTL2|=Y%, the ΔTL2 value can be determined. Then, the TL2 value is locked, and the voltage value corresponding to the TL2 value is obtained. The collected light signal is then converted into an electrical signal by the induction controller 16. The electrical signal is matched and set with the voltage value corresponding to the TL2 value to realize the linkage between the transition layer 13 and the optical element layer 12.

[0048] The absolute value of the difference between △TL1 and △TL2 is ≤3%, specifically, it can be 3%, 2.5%, 2%, 1.5%, 1%, 0.5%, or 0, etc. Preferably, 0≤Y≤2, more preferably, 0≤Y≤1. This embodiment limits the absolute value of the difference between △TL1 and △TL2 to control the visible light transmittance of the optical element layer 12 and the transition layer 13 to be similar or equal in different environments. No matter how the environment changes, when the user observes the laminated glass 1 with their eyes, the transition layer 13 and the optical element can be almost imperceptibly changed, which better realizes the natural connection between the transition layer 13 and the optical element layer 12, further improving the appearance performance of the laminated glass 1 and further improving the user experience.

[0049] In related technologies, the sealant cannot adjust the visible light transmittance. The visible light transmittance of the sealant is 80%. When the maximum value of TL of the optical element layer 12 is taken, the absolute value of the difference between the visible light transmittance change value of the sealant and the optical functional area 121 is 33.2, which is much greater than 3, resulting in an abrupt transition between the optical element layer 12 and the sealant.

[0050] In one embodiment, the transition region 131 has Lab1 values ​​for the color of visible light reflected: L1, a1, b1; the optical functional region 121 has Lab2 values ​​for the color of visible light reflected: L2, a2, b2; wherein the laminated glass 1 satisfies the following conditions: △E≤3.5.

[0051] The color difference value △E ≤ 3.5, specifically, can be 3, 2.5, 2, 1.5, 1, 0.5, or 0, etc., preferably △E ≤ 2. This embodiment controls the optical element layer 12 and the transition layer 13 to have similar or equal colors in different environments by limiting the color difference value △E. No matter how the environment changes, when the user observes the laminated glass 1 with their eyes, the transition layer 13 and the optical element can be almost imperceptibly changed, which better realizes the natural connection between the transition layer 13 and the optical element layer 12, further improving the appearance performance of the laminated glass 1 and further improving the user experience.

[0052] In one embodiment, the transition region 131 has transmission Lab1 values ​​for the reflected color of visible light: transmission L1, transmission a1, and transmission b1; the optical functional region 121 has transmission Lab2 values ​​for the reflected color of visible light: transmission L2, transmission a2, and transmission b2; wherein the laminated glass 1 satisfies the following conditions: Transmission E≤3.5.

[0053] The transmission Lab value refers to the Lab value of the color obtained through transmission measurement. Δtransmission E ≤ 3.5, specifically examples include 3, 2.5, 2, 1.5, 1, 0.5, or 0, etc., preferably Δtransmission E ≤ 2. This embodiment, by limiting the transmission color difference value Δtransmission E, further controls the optical element layer 12 and the transition layer 13 to have similar or equal colors under different environments, thereby better achieving a natural connection between the transition layer 13 and the optical element layer 12, further improving the appearance performance of the laminated glass 1, and further enhancing the user experience.

[0054] In the relevant technology, the color of the sealing adhesive cannot be adjusted, and the transmission color difference value Δtransmission E between the sealing adhesive and the optical functional area 121 is 46.3, which is much greater than 3.5, resulting in an abrupt color transition between the optical element layer 12 and the sealing adhesive.

[0055] In one embodiment, the transition region 131 has reflection Lab1 values ​​for visible light: reflection L1, reflection a1, and reflection b1; the optical functional region 121 has reflection Lab2 values ​​for visible light: reflection L2, reflection a2, and reflection b2; wherein the laminated glass 1 satisfies the following conditions: △reflection E≤3.5.

[0056] The Lab value of reflection refers to the color of light reflected from the surface of an object in the Lab color space. Δreflection E ≤ 3.5, specifically examples include 3, 2.5, 2, 1.5, 1, 0.5, or 0, etc., preferably Δreflection E ≤ 2. This embodiment, by limiting the reflection color difference value Δreflection E, further controls the optical element layer 12 and the transition layer 13 to have similar or equal colors under different environments, thereby better achieving a natural connection between the transition layer 13 and the optical element layer 12, further improving the appearance performance of the laminated glass 1, and further enhancing the user experience.

[0057] In the relevant technology, the color of the sealing adhesive cannot be adjusted. The color difference value Δreflection E between the sealing adhesive and the optical functional area 121 is 46.3, which is much greater than 3.5, resulting in an abrupt color transition between the optical element layer 12 and the sealing adhesive.

[0058] Please refer to Figures 1 and 2 together. In one embodiment, the laminated glass 1 includes a first surface 1a and a second surface 1b disposed opposite to each other. The first surface 1a is farther from the ground than the second surface 1b. The transition layer 13 is disposed between the optical element layer 12 and the first surface 1a.

[0059] The first surface 1a can also be understood as the top edge of the laminated glass 1, and the second surface 1b can also be understood as the bottom edge of the laminated glass 1. In related technologies, when the laminated glass 1 is applied to a vehicle, during the lifting and lowering process of the laminated glass 1, the area between the upper optical element layer 12 and the glass boundary will be exposed in the field of vision, resulting in abrupt color transition, which reduces the appearance performance of the laminated glass 1 and reduces the user's experience.

[0060] The transition layer 13 is disposed above the optical element layer 12, that is, the transition layer 13 is disposed between the optical element layer 12 and the first surface 1a of the laminated glass 1. During the lifting and lowering process of the laminated glass 1, since the transition layer 13 can maintain a visible light transmittance and color similar to or the same as that of the optical element layer 12, the transition layer 13 and the optical element layer 12 are naturally connected, which improves the user experience and solves the problem of uneven transition between the transition layer 13 and the optical element layer 12.

[0061] Please refer to Figures 3 and 4 together. In one embodiment, the transition layer 13 is disposed around the periphery of the optical element layer 12.

[0062] The transition layer 13 is disposed above, below, to the left and to the right of the optical element layer 12. That is, the transition layer 13 is disposed around the optical element layer 12. The transition layer 13 can maintain a visible light transmittance and color similar to or the same as the optical element layer 12, thereby ensuring that the transition layer 13 and the optical element layer 12 are naturally connected no matter how the laminated glass 1 is moved, which further improves the user experience and solves the problem of uneven transition between the transition layer 13 and the optical element layer 12.

[0063] Please refer to Figures 1-3. In one embodiment, the laminated glass 1 further includes a sensor controller 16 electrically connected to the optical element layer 12. The sensor controller 16 is used to acquire change information of the transition layer 13 and to regulate the optical element layer 12 so that the optical element layer 12 has a preset visible light transmittance and a preset color.

[0064] The sensing controller 16 can be a controller with a photoresistor. For example, when the material of the transition layer 13 is selected from a photochromic material, the transition layer 13 has different visible light transmittance and different colors as the amount of irradiation received by the transition layer 13 changes. According to the change in the transition layer 13, the resistance value of the photoresistor also changes, so that the sensing controller 16 can acquire information about the change in the transition layer 13; the sensing controller 16 adjusts the voltage applied to the optical element layer 12 according to the information about the change in the transition layer 13, so that the optical element layer 12 has a visible light transmittance and color similar to or the same as that of the transition layer 13. Optionally, the sensing controller 16 is disposed on the transition layer 13. The sensing controller 16 is disposed between the first glass plate 10 and the second glass plate 15. The sensing controller 16 is disposed on the first adhesive layer 11 or the second adhesive layer 14.

[0065] In summary, this embodiment achieves linkage between the optical element layer 12 and the transition layer 13 by setting the induction controller 16, thereby realizing a natural connection between the transition layer 13 and the optical element layer 12, improving the appearance performance of the laminated glass 1, enhancing the user experience, and solving the problem of uneven transition between the transition layer 13 and the optical element layer 12.

[0066] Please refer to Figures 1-4. In one embodiment, the first adhesive layer 11 includes a first transition portion 111 located in the transition region 131, and the second adhesive layer 14 includes a second transition portion 141 located in the transition region 131. The transition layer 13 is disposed between the first transition portion 111 and the second transition portion 141. Under different preset conditions, the first transition portion 111 and the second transition portion 141 have different visible light transmittance and different colors.

[0067] The first adhesive layer 11 includes a first adhesive portion 112 located in the optical functional region 121 and a first transition portion 111 located in the transition region 131. The first adhesive portion 112 is connected to the first transition portion 111; or, the first adhesive portion 112 and the first transition portion 111 are spaced apart. The first adhesive portion 112 bonds the first glass plate 10 to the optical element layer 12. The first transition portion 111 bonds the first glass plate 10 to the transition layer 13. The second adhesive layer 14 includes a second adhesive portion 142 located in the optical functional region 121 and a second transition portion 141 located in the transition region 131. The second adhesive portion 142 is connected to the second transition portion 141; or, the second adhesive portion 142 and the second transition portion 141 are spaced apart. The second adhesive portion 142 bonds the second glass plate 15 to the optical element layer 12. The second transition portion 141 bonds the second glass plate 15 to the transition layer 13. The first adhesive portion 112 and the second adhesive portion 142 can be transparent thermoplastic polymer films or colored thermoplastic polymer films. The materials of the first transition section 111 and the second transition section 141 are selected from at least one of photochromic materials, thermochromic materials, and pressure-sensitive materials.

[0068] In summary, this embodiment provides a first transition portion 111 and a second transition portion 141 in the transition region 131. The first transition portion 111 and the second transition portion 141 can have visible light transmittance and color similar to or the same as the optical element layer 12, thereby achieving a natural connection between the transition layer 13 and the optical element layer 12. This further improves the appearance performance of the laminated glass 1, enhances the user experience, and better solves the problem of uneven transition between the transition layer 13 and the optical element layer 12.

[0069] Please refer to Figures 1-4. In one embodiment, the laminated glass 1 further includes a sensor controller 16 electrically connected to the optical element layer 12. The sensor controller 16 is disposed in the first transition portion 111 or the second transition portion 141.

[0070] The sensor controller 16 is electrically connected to the optical element layer 12. The sensor controller 16 is used to acquire information about changes in the transition layer 13, the first transition portion 111, and the second transition portion 141. It is also used to regulate the optical element layer 12 to achieve a preset visible light transmittance and a preset color. For example, the sensor controller 16 is embedded in the first transition portion 111 or the second transition portion 141. Alternatively, the sensor controller 16 may be located between the first transition portion 111 and the first adhesive portion 112; or between the second transition portion 141 and the second adhesive portion 142.

[0071] For example, when the materials of the transition layer 13, the first transition portion 111, and the second transition portion 141 are selected from photochromic materials, as the amount of irradiation received by the transition layer 13, the first transition portion 111, and the second transition portion 141 changes, the transition layer 13, the first transition portion 111, and the second transition portion 141 will have different visible light transmittance and different colors. According to the changes in the transition layer 13, the first transition portion 111, and the second transition portion 141, the resistance value of the photoresistor also changes, so that the sensing controller 16 can obtain the change information of the transition layer 13, the first transition portion 111, and the second transition portion 141; the sensing controller 16 adjusts the voltage value applied to the optical element layer 12 according to the change information of the transition layer 13, the first transition portion 111, and the second transition portion 141, so that the optical element layer 12 has a visible light transmittance and color similar to or the same as that of the transition layer 13, the first transition portion 111, and the second transition portion 141.

[0072] In summary, this embodiment provides the sensor controller 16 to the first transition section 111 or the second transition section 141 so that the sensor controller 16 can obtain change information of the transition layer 13, the first transition section 111, and the second transition section 141, which facilitates disassembly and assembly. Furthermore, the sensor controller 16 is located around the laminated glass 1, which reduces the interference of the sensor controller 16 on the main viewing area of ​​the laminated glass 1 and improves the driving reliability of the vehicle.

[0073] This application also provides a vehicle, the vehicle including a body and laminated glass as described above, the laminated glass being disposed at an opening in the body.

[0074] The vehicle provided in this application, by employing the laminated glass described above, incorporates transition layers with different visible light transmittance and colors on the laminated glass. These transition layers possess visible light transmittance and color similar to or identical to the optical element layer, achieving a natural connection between the transition layer and the optical element layer. This improves the appearance of the laminated glass, enhances the user experience, and resolves the problem of uneven color transition between the transition layer and the optical element layer. Furthermore, it eliminates the need for black edge printing on the laminated glass, reducing manufacturing costs and simplifying the manufacturing process.

[0075] To make the objectives and advantages of this application clearer, the effects of the reflective element of this application will be further explained in detail below with reference to specific embodiments.

[0076] Example 1:

[0077] Please refer to Table 1, Table 2, Figure 5, and Figure 6. Table 1 shows the relationship between solar irradiance and visible light transmittance in the transition layer. Table 2 shows the relationship between voltage and visible light transmittance in the optical element layer. Figure 5 shows the curve relationship between solar irradiance and visible light transmittance in the transition layer. Figure 6 shows the curve relationship between voltage and visible light transmittance in the optical element layer.

[0078] Table 1. Relationship between solar irradiance and visible light transmittance in the transition layer.

[0079] Table 2. Correspondence between voltage values ​​and visible light transmittance in optical element layers.

[0080] Based on the above data, it can be seen that the relationship between solar irradiance and TL1 is determined by the photochromic material in the transition layer itself. Under a certain irradiance, the photochromic material has its corresponding TL1 value. Combining |△TL1-△TL2|=Y%, the △TL2 value is determined, and then the TL2 value is locked. The voltage value corresponding to TL2 is determined using the curve in Figure 6. Then, the collected light signal is converted into an electrical signal by the induction controller, and the electrical signal is matched and set with the voltage value corresponding to TL2 to realize the linkage between the transition layer and the optical element layer.

[0081] Example 2:

[0082] Please refer to Tables 3 and 4. Table 3 shows the specific data of the transmission Lab value and Δtransmission E of laminated glass under different irradiation levels, and Table 4 shows the specific data of the reflection Lab value and Δreflection E of laminated glass under different irradiation levels.

[0083] Table 3. Specific data on Lab value and Δtransmission E of laminated glass under different irradiation levels.

[0084] Table 4. Specific data on Lab value and Δreflectance E of laminated glass under different irradiation levels.

[0085] In related technologies, the transmission values ​​L3, transmission a3, transmission b3, and reflection values ​​L3, reflection a3, and reflection b3 in the transition region are 91.1, -5.66, 2.88, 31.74, -2.29, and 0.34, respectively. These values ​​correspond to the optical functional region Δtransmission E. min The value is 27.21, and the Δreflection E is... minThe values ​​are 4.10, all greater than 3.5, resulting in an abrupt color transition between the optical element layer and the sealing adhesive. However, this application controls the optical element layer and the transition layer to have similar or equal colors under different environments by limiting the transmission color difference value ΔtransmissionE and the reflection color difference value ΔreflectionE, thereby achieving a better natural connection between the transition layer and the optical element layer, further improving the appearance performance of the laminated glass, and further enhancing the user experience.
