Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly relates to a glass plate, laminated glass and a vehicle. Background Art

[0002] During the driving of a vehicle, the vehicle glass provides a clear field of vision for the driver, enabling the driver to observe the road and traffic conditions. During daytime driving, when irradiated by high-angle dazzling sunlight, the driver usually uses a sun visor or a sunshade ribbon layer. However, when using a sun visor, the light on the side can also enter the human eye. Moreover, when using a sunshade ribbon, the existing sunshade ribbon has a fixed light transmittance and cannot change with the external environment. If the light is dim on a cloudy day, the visible sunshade ribbon appears dark, creating a depressing environment inside the vehicle. In addition, the surface of the existing vehicle glass is prone to adsorbing dust, and the dust accumulates on the surface of the vehicle glass, thereby reducing the clarity of the vehicle glass and affecting the driver's line of sight. Especially during night oncoming vehicle process, the dust accumulated in the front windshield for a long time forms a layer of fog shadow on the inner surface, which is extremely likely to affect the line of sight and cause problems in vehicle driving safety.

[0038] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0039] It should be noted that for the convenience of description, in the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, the detailed description of the same components is omitted in different embodiments.

[0040] During the driving of a vehicle, the vehicle glass provides a clear view for the driver, enabling the driver to observe the road and traffic conditions. During daytime driving, when the sun shines at a high angle and is dazzling, the driver usually uses a sun visor or a sunshade ribbon layer. However, when using a sun visor, side light can also enter the eyes. Moreover, when using a sunshade ribbon, the existing sunshade ribbon has a fixed light transmittance and cannot change with the external environment. If it is cloudy and the light is dim, the visible sunshade ribbon layer appears dark when looking up, creating a depressing environment inside the vehicle. In addition, the surface of the existing vehicle glass is prone to adsorbing dust, and the dust accumulates on the surface of the vehicle glass, thereby reducing the clarity of the vehicle glass and affecting the driver's line of sight. Especially during night-time oncoming vehicle encounters, the dust that has accumulated on the inner surface of the front windshield for a long time forms a layer of fog shadow on the inner surface, which is extremely likely to affect the line of sight and cause problems with vehicle driving safety.

[0041] Please refer to Figures 1 to 3 , the embodiment of the present application provides a glass plate 100, which includes: a glass layer 10; a functional layer 20, the functional layer 20 is disposed on one side of the glass layer 10; and a self-cleaning layer 30, the self-cleaning layer 30 is disposed on the side of the functional layer 20 away from the glass layer 10 or on the side of the glass layer 10 away from the functional layer 20, and the self-cleaning layer 30 has a plurality of protruding structures 31 on the surface of the self-cleaning layer 30 away from the glass layer 10, and the plurality of protruding structures 31 are spaced apart.

[0042] Optionally, the glass plate 100 of the present application can be applied to a vehicle 300, a building exterior wall, a window, a glass curtain wall, a roof, a skylight, etc. Optionally, the glass plate 100 of the embodiment of the present application can be applied to vehicles 300 such as cars, sedans, trucks, freight cars, trains, etc. Optionally, the glass plate 100 of the present application can be the front windshield, rear windshield, side window glass, and roof skylight glass of the vehicle 300, etc.

[0043] It can be understood that the functional layer 20 can be disposed on one or more surfaces of the glass layer 10, and the functional layer 20 can also be disposed on the whole or a part of one surface of the glass layer 10.

[0044] It can be understood that the self-cleaning layer 30 and the functional layer 20 can be disposed on the same side of the glass layer 10 (as Figure 2 shown), or can be respectively disposed on opposite sides of the glass layer 10 (as Figure 3 shown). When the self-cleaning layer 30 and the functional layer 20 are disposed on the same side of the glass layer 10, the glass layer 10, the functional layer 20, and the self-cleaning layer 30 are sequentially stacked. When the self-cleaning layer 30 and the functional layer 20 are respectively disposed on opposite sides of the glass layer 10, the functional layer 20, the glass layer 10, and the self-cleaning layer 30 are sequentially stacked.

[0045] Understandably, the self-cleaning coating has the property of resisting dust adsorption. The detection method for the dust adsorption resistance performance of the self-cleaning coating can be to evenly sprinkle 200-mesh talcum powder on the glass coated with the self-cleaning layer 30 using a sieve, simulate the air volume of the vehicle air conditioner, and blow the glass at an angle of 25° with a fan at a speed of 2 m / s. If the dust can be completely cleaned visually, it is considered effective.

[0046] When the glass plate 100 serves as the front windshield of the vehicle 300, the functional layer 20 is disposed near the top of the vehicle 300.

[0047] The glass plate 100 according to the embodiment of the present application includes a glass layer 10; a functional layer 20 disposed on one side of the glass layer 10; and a self-cleaning layer 30 disposed on the side of the functional layer 20 away from the glass layer 10 or on the side of the glass layer 10 away from the functional layer 20. The self-cleaning layer 30 has a plurality of convex structures 31 on the surface facing away from the glass layer 10, and the plurality of convex structures 31 are spaced apart. The glass plate 100 of the present application further includes a self-cleaning layer 30, and the surface of the self-cleaning layer 30 has a plurality of convex structures 31 spaced apart, so that the self-cleaning layer 30 is not easily adsorbed with dust (that is, has the property of resisting dust adsorption). Even if a small amount of dust is adsorbed on the self-cleaning layer 30 after a period of use, through the air volume of the vehicle-mounted air conditioner of the vehicle 300, the small amount of dust can be easily blown off for cleaning, eliminating manual cleaning and achieving the purpose of waterless self-cleaning. Thereby, when the glass plate 100 of the present application is applied to the vehicle 300, it can better avoid the reduction of the light transmittance of the glass plate 100 caused by dust adsorption, improve the line of sight of the driver in the vehicle 300, and improve driving safety.

[0048] Please refer to Figure 4 , in one embodiment, the width w of the convex structure 31 ranges from 20 nm ≤ w ≤ 50 nm.

[0049] It should be noted that the width w of the convex structure 31 refers to the distance between the two points farthest apart on the positive projection of the convex structure 31 on the surface of the glass layer 10 facing the self-cleaning layer 30.

[0050] Specifically, the width w of the protrusion structure 31 can be, but is not limited to, 20 nm, 22 nm, 24 nm, 26 nm, 28 nm, 30 nm, 35 nm, 40 nm, 45 nm, 50 nm, etc. If the width of the protrusion structure 31 is too small, the anti-static adsorption ability of the self-cleaning layer 30 is reduced, making it easy for the self-cleaning layer 30 to adsorb dust, making it difficult to achieve the anti-dust adsorption effect and the self-cleaning effect; if the width of the protrusion structure 31 is too large, the roughness of the surface of the self-cleaning layer 30 facing away from the glass plate 100 is too large, and the gaps between the protrusion structures 31 are too large, which easily accumulates fine dust at the micro-nano level, similarly affecting the anti-static adsorption effect and the self-cleaning effect of the self-cleaning layer 30. In addition, if the width of the protrusion structure 31 is too large, the light transmittance of the self-cleaning layer 30 is reduced, thereby reducing the light transmittance of the glass plate 100. When the glass plate 100 is used in the vehicle 300, the light transmittance of the glass plate 100 is too low, which is not conducive to driving safety.

[0051] In this embodiment, by controlling the width of the raised structure 31, the self-cleaning layer 30 can have a good anti-static adsorption effect, reducing the accumulation of dust on the surface of the glass plate 100, so that the surface of the glass plate 100 has better clarity. When the glass plate 100 is applied to the front windshield of the vehicle 300, it can bring a good visual experience to the driver.

[0052] See also Figure 4 In one embodiment, the distance s between two adjacent protrusion structures 31 is in the range of 20 nm ≤ s ≤ 50 nm.

[0053] It should be noted that the spacing s between two adjacent protrusion structures 31 refers to the minimum distance between two adjacent protrusion structures 31 on the orthographic projection of the surface of the glass layer 10 facing the self-cleaning layer 30 .

[0054] Specifically, the spacing s between two adjacent protrusion structures 31 may be, but is not limited to, 20 nm, 22 nm, 24 nm, 26 nm, 28 nm, 30 nm, 35 nm, 40 nm, 45 nm, 50 nm, etc.

[0055] When the spacing between two adjacent raised structures 31 is too small, the roughness of the surface of the self-cleaning layer 30 away from the glass plate 100 is too small, and the gap between the two adjacent raised structures 31 is small, which reduces the anti-static adsorption ability of the self-cleaning layer 30, making it easy for the self-cleaning layer 30 to adsorb dust, and it is difficult to achieve the anti-dust adsorption effect and self-cleaning effect; when the spacing between two adjacent raised structures 31 is too large, the roughness of the surface of the self-cleaning layer 30 away from the glass plate 100 is too large, and the gap between the two adjacent raised structures 31 is too large, which easily accumulates fine dust at the micro-nano level, and also affects the anti-static adsorption effect and self-cleaning effect of the self-cleaning layer 30. In addition, the spacing between the two adjacent raised structures 31 is too large, which will reduce the light transmittance of the self-cleaning layer 30, thereby reducing the light transmittance of the glass plate 100. When the glass plate 100 is applied to the vehicle 300, the light transmittance of the glass plate 100 is too low, which is not conducive to driving safety.

[0056] In this embodiment, by controlling the distance between two adjacent protrusion structures 31, the self-cleaning layer 30 can have a good anti-static adsorption effect, reduce the accumulation of dust on the surface of the glass plate 100, and thus make the surface of the glass plate 100 have better clarity. When the glass plate 100 is applied to the front windshield of the vehicle 300, it can bring a good visual experience to the driver.

[0057] See also Figure 4 In one embodiment, along the stacking direction of the glass layer 10 and the self-cleaning layer 30 , the height h of the protruding structure 31 is in the range of 20 nm ≤ h ≤ 50 nm.

[0058] In other words, along the stacking direction of the glass layer 10 and the self-cleaning layer 30 , the maximum height h of the protrusion structure 31 is in the range of 20 nm ≤ h ≤ 50 nm.

[0059] Specifically, the height h of the protrusion structure 31 can be, but is not limited to, 20 nm, 22 nm, 24 nm, 26 nm, 28 nm, 30 nm, 35 nm, 40 nm, 45 nm, 50 nm, etc.

[0060] When the height of the convex structure 31 is too small, the roughness of the surface of the self-cleaning layer 30 facing away from the glass plate 100 is too small, reducing the antistatic adsorption ability of the self-cleaning layer 30, making the self-cleaning layer 30 prone to dust adsorption and difficult to achieve the dust adsorption resistance effect and the self-cleaning effect; when the height h of the convex structure 31 is too large, the roughness of the surface of the self-cleaning layer 30 facing away from the glass plate 100 is too large, and the height of the convex structure 31 is too large, which is prone to accumulating fine dust at the micro-nano level, and will also affect the antistatic adsorption effect and the self-cleaning effect of the self-cleaning layer 30. In addition, when the height of the convex structure 31 is too large, it will reduce the light transmittance of the self-cleaning layer 30, thereby reducing the light transmittance of the glass plate 100. When the glass plate 100 is applied to the vehicle 300, the too low light transmittance of the glass plate 100 is not conducive to driving safety.

[0061] In this embodiment, by controlling the height h of the convex structure 31, the self-cleaning layer 30 can have a good antistatic adsorption effect, reduce the dust accumulation on the surface of the glass plate 100, so that the surface of the glass plate 100 has better clarity. When the glass plate 100 is applied to the front windshield of the vehicle 300, it can bring a good visual experience to the driver.

[0062] In one embodiment, the range of the surface roughness Ra of the self-cleaning layer 30 facing away from the glass layer 10 is 0.025 μm ≤ Ra ≤ 0.05 μm; the range of the surface roughness Rz of the self-cleaning layer 30 facing away from the glass layer 10 is 0.1 μm ≤ Rz ≤ 0.4 μm.

[0063] It can be understood that the surface roughness Ra of the self-cleaning layer 30 facing away from the glass layer 10 is any value between 0.025 μm and 0.050 μm. Specifically, the surface roughness Ra of the self-cleaning layer 30 facing away from the glass layer 10 can be, but is not limited to, 0.025 μm, 0.030 μm, 0.035 μm, 0.040 μm, 0.045 μm, 0.050 μm, etc. When the surface roughness Ra of the self-cleaning layer 30 facing away from the glass layer 10 is too small, the antistatic adsorption ability of the self-cleaning layer 30 is reduced, making the self-cleaning layer 30 prone to dust adsorption and difficult to achieve the dust adsorption resistance effect and the self-cleaning effect; when the surface roughness Ra of the self-cleaning layer 30 facing away from the glass layer 10 is too large, the gap between the convex structures 31 is too large, which is prone to accumulating fine dust at the micro-nano level, and will also affect the antistatic adsorption effect and the self-cleaning effect of the self-cleaning layer 30. In addition, when the surface roughness Ra of the self-cleaning layer 30 facing away from the glass layer 10 is too large, it will reduce the light transmittance of the self-cleaning layer 30, thereby reducing the light transmittance of the glass plate 100. When the glass plate 100 is applied to the vehicle 300, the too low light transmittance of the glass plate 100 is not conducive to driving safety.

[0064] Optionally, the roughness Rz of the surface of the self-cleaning layer 30 facing away from the glass layer 10 is 0.10 μm, 0.15 μm, 0.20 μm, 0.25 μm, 0.30 μm, 0.35 μm, 0.40 μm, etc. When the roughness Rz of the surface of the self-cleaning layer 30 away from the glass layer 10 is too small, the anti-static adsorption ability of the self-cleaning layer 30 is reduced, making the self-cleaning layer 30 easily adsorb dust, and it is difficult to achieve the anti-dust adsorption effect and the self-cleaning effect; when the roughness Rz of the surface of the self-cleaning layer 30 away from the glass layer 10 is too large, it is easy to accumulate fine dust at the micro-nano level, which will also affect the anti-static adsorption effect and the self-cleaning effect of the self-cleaning layer 30. In addition, the roughness Rz of the surface of the self-cleaning layer 30 away from the glass layer 10 is too large, which will reduce the transmittance of the self-cleaning layer 30, thereby reducing the transmittance of the glass plate 100. When the glass plate 100 is applied to the vehicle 300, the transmittance of the glass plate 100 is too low, which is not conducive to driving safety.

[0065] In this embodiment, by controlling the roughness of the surface of the self-cleaning layer 30 away from the glass layer 10, the self-cleaning layer 30 can have a better anti-static adsorption effect, while reducing the accumulation of dust on the surface of the glass plate 100, so that the surface of the glass plate 100 has better clarity. When the glass plate 100 is applied to the front windshield of the vehicle 300, it can bring a good visual experience to the driver.

[0066] Please refer again Figure 2 In one embodiment, along the stacking direction of the color-changing layer and the self-cleaning layer 30 of the glass layer 10 , the thickness d1 of the self-cleaning layer 30 is in the range of 40 nm ≤ d1 ≤ 60 nm.

[0067] Specifically, the thickness d1 of the self-cleaning layer 30 may be, but is not limited to, 40 nm, 42 nm, 46 nm, 48 nm, 50 nm, 52 nm, 54 nm, 56 nm, 58 nm, 60 nm, etc. If the thickness d1 of the self-cleaning layer 30 is too small, the antistatic adsorption effect and the self-cleaning effect of the self-cleaning layer 30 are reduced; if the thickness d1 of the self-cleaning layer 30 is too large, the antistatic adsorption performance and the self-cleaning performance of the self-cleaning layer 30 will not be improved, but the cost of the self-cleaning layer 30 will be increased, and the light transmittance of the self-cleaning layer 30 will be reduced.

[0068] In this embodiment, the thickness of the self-cleaning layer 30 can be controlled so that the surface of the glass plate 100 has a good self-cleaning effect and the cost of the self-cleaning layer 30 is saved.

[0069] Optionally, the self-cleaning layer 30 is an antistatic layer, which can better improve the anti-dust adsorption effect and self-cleaning effect of the self-cleaning layer 30.

[0070] It should be noted that the self-cleaning layer 30 is an antistatic layer. In some embodiments, the antistatic layer is a hydrophilic antistatic layer. The hydrophilicity of the surface of the self-cleaning layer 30 can form a fine water film layer on its surface, further reducing the friction coefficient between the dust and the contact surface of the self-cleaning layer 30, so that the dust is not easily adsorbed on the surface of the glass plate 100.

[0071] Optionally, the material of the self-cleaning layer 30 includes silica and conductive particles. Optionally, the conductive particles are nano-scale conductive particles.

[0072] Optionally, the conductive particles can be, but are not limited to, at least one of tin oxide (SnO2), tungsten oxide (WO3), platinum (Pt), silver (Ag), etc. These conductive particles have higher chemical resistance, thereby improving the chemical resistance of the self-cleaning layer 30. In addition, these conductive particles can reduce the impedance value and resistance value of the surface of the glass layer 10, making the charge on the surface of the glass layer 10 easy to disperse and increasing the antistatic adsorption ability of the self-cleaning layer 30. In addition, the tungsten oxide and the platinum nanoparticles improve the chemical resistance without reducing the visible light transmittance.

[0073] Optionally, the particle size range of the silica is 20 nm to 50 nm. Specifically, the particle size of the silica can be, but is not limited to, 20 nm, 22 nm, 24 nm, 26 nm, 28 nm, 30 nm, 35 nm, 40 nm, 45 nm, 50 nm, etc. Using silica with this particle size range as the material of the self-cleaning layer 30 can reduce the contact area between the dust and the surface of the self-cleaning layer 30 and reduce the friction force. Even if the dust adheres, the dust can easily fall off from the self-cleaning layer 30, thus achieving the self-cleaning effect.

[0074] Optionally, the particle size of the conductive particles can be 8 nm to 13 nm. Specifically, the particle size of the conductive particles can be, but is not limited to, 8 nm, 9 nm, 10 nm, 11 nm, 12 nm, 13 nm, etc.

[0075] Optionally, the resistance value range of the surface of the glass plate 100 is 10 6 Ω to 10 9 Ω, making the charge on the surface of the glass plate 100 easy to disperse and increasing the antistatic adsorption ability of the self-cleaning layer 30.

[0076] Optionally, the functional layer 20 includes at least one of a heat insulation layer, a sound insulation layer, a light dimming layer, a color changing layer, and a display layer.

[0077] In this embodiment, when the functional layer 20 is a heat-insulating layer, the glass plate 100 can have a good heat-insulating effect. When the glass plate 100 is applied to a vehicle, it can better prevent the temperature inside the vehicle from being too high, thereby improving the user experience. When the functional layer 20 is a sound-insulating layer, the glass plate 100 can have a good sound-insulating effect. When the glass plate 100 is applied to a vehicle, it can reduce the noise inside the vehicle and improve the riding comfort. When the functional layer 20 is a light-adjusting layer or a color-changing layer, the light transmittance of the functional layer 20 can be adjusted, thereby adjusting the light transmittance of the glass plate 100. For example, when the ambient light is dim, the color of the functional layer 20 can be adjusted to become lighter, increasing the light transmittance of the glass plate 100, thereby improving the line of sight of the people inside the vehicle. When the ambient light is bright, the color of the functional layer 20 can be adjusted to become darker, reducing the light transmittance of the glass plate 100, thereby preventing the light from being too dazzling and affecting driving safety. The light transmittance of the glass plate 100 of the present application has good adjustability, and when applied to a vehicle 300, it can better improve the driving safety of the vehicle 300. When the functional layer 20 is a display layer, the glass plate 100 can have a display function, such as a head-up display, etc.

[0078] It should be noted that when the functional layer 20 includes a color-changing layer, the color of the functional layer 20 can be adjusted, thereby changing the visible light transmittance of the functional layer 20. In a specific embodiment, when the external environment is dim, the light transmittance of the functional layer 20 is increased to increase the light transmittance of the glass plate 100. Thus, when the glass plate 100 is applied to a vehicle 300, the intensity of the light inside the vehicle can be increased. When the external environment is bright, the color of the functional layer 20 is deepened, and the light transmittance of the functional layer 20 is reduced to prevent the light inside the vehicle from being too dazzling and affecting driving safety when the glass plate 100 is applied to the front windshield of the vehicle 300.

[0079] Please refer to again Figure 2 In one embodiment, along the stacking direction of the glass layer 10, the functional layer 20, and the self-cleaning layer 30, the thickness d2 of the functional layer 20 ranges from 5 μm ≤ d2 ≤ 7 μm.

[0080] Specifically, the thickness d2 of the functional layer 20 can be, but is not limited to, 5.0 μm, 5.2 μm, 5.4 μm, 5.6 μm, 5.8 μm, 6.0 μm, 6.2 μm, 6.4 μm, 6.6 μm, 6.8 μm, 7.0 μm, etc. If the thickness d2 of the functional layer 20 is too small and the functional layer 20 is too thin, the color depth after the color change of the functional layer 20 will not be sufficient, and the shading effect cannot be achieved, that is, the adjustment range of the light transmittance of the functional layer 20 becomes smaller, and when the light transmittance needs to be reduced, the reduction of the light transmittance is limited. If the thickness d2 of the functional layer 20 is too large and the functional layer 20 is too thick, the cost of the functional layer 20 is increased.

[0081] In this embodiment, the thickness of the functional layer 20 can be controlled, so that the functional layer 20 has a good sunshade effect and does not waste the raw materials of the functional layer 20.

[0082] Please refer to Figure 5 , in one embodiment, the functional layer 20 includes a dimming layer or a color-changing layer. Along the extension plane of the glass layer 10, the line width L of the functional layer 20 ranges from 10 cm ≤ L ≤ 15 cm.

[0083] Optionally, the line width L of the functional layer 20 can be, but is not limited to, 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, etc. If the line width of the functional layer 20 is too small, it is impossible to avoid the irradiation of high-angle dazzling sunlight, which is extremely likely to cause vision problems and lead to problems with the driving safety of the vehicle 300; if the line width of the functional layer 20 is too large, the area of the functional layer 20 on the surface of the glass layer 10 is too large. When the functional layer 20 changes from colorless to dark, the area of the functional layer 20 is too large, affecting the driver's line of sight and driving safety. When the line width L of the functional layer 20 ranges from 10 cm ≤ L ≤ 15 cm, on the basis that the functional layer 20 does not affect the driver's line of sight, the problem of vision impairment caused by the irradiation of high-angle dazzling sunlight is avoided, thereby avoiding problems with the safety of the vehicle 300 during driving and ensuring driving safety.

[0084] In some embodiments, the color-changing layer can be a photochromic layer or an electrochromic layer.

[0085] When the environmental light intensity is lower than a preset value, the color-changing layer has a first light transmittance, and the first light transmittance T1 ≥ 75%. Optionally, the first light transmittance T1 can be, but is not limited to, 75%, 80%, 85%, 90%, 95%, 99%, etc.

[0086] When the environmental light intensity is lower than a preset value, the color-changing layer has a second light transmittance, and the second light transmittance T2 ≤ 23%. Optionally, the second light transmittance T2 can be, but is not limited to, 23%, 20%, 15%, 10%, 5%, 1%, etc.

[0087] It can be understood that the light transmittance of the color-changing layer can be adjusted between the first light transmittance and the second light transmittance.

[0088] In a specific embodiment, when the ambient light intensity is lower than a preset value, the first light transmittance of the color-changing layer is 90%, and when the ambient light intensity is lower than the preset value, the second light transmittance of the color-changing layer is 20%. The light transmittance of the color-changing layer can be adjusted between 20% and 90%. In another specific embodiment, when the ambient light intensity is lower than the preset value, the first light transmittance of the color-changing layer is 95%, and when the ambient light intensity is lower than the preset value, the second light transmittance of the color-changing layer is 18%. The light transmittance of the color-changing layer can be adjusted between 19% and 95%.

[0089] In some embodiments, the color-changing layer is a photochromic layer. Under illumination with light of different intensities, the color-changing layer can change color, thereby adjusting the light transmittance of the photochromic layer, and further adjusting the light transmittance of the corresponding functional layer 20 region of the glass plate 100.

[0090] Optionally, the photochromic layer includes a resin and color-changing molecules.

[0091] Optionally, the resin can be, but is not limited to, at least one of polymethyl methacrylate (PMMA) and polyvinyl butyral (PVB).

[0092] Optionally, the color-changing molecules can be, but are not limited to, at least one of organic color-changing molecules and inorganic color-changing molecules.

[0093] Optionally, the color-changing molecules can be materials that can be irradiated and changed in color at wavelengths above 380 nm.

[0094] Optionally, the organic color-changing molecules can be, but are not limited to, at least one of spiropyran, diarylethene, spirooxazine, etc.

[0095] Optionally, the color-changing layer can also be an inorganic material, such as, but not limited to, tungsten oxide.

[0096] Optionally, the photochromic layer also includes antioxidants, etc. In some embodiments, the resin, organic color-changing molecules, and antioxidants are mixed to form a slurry, and the slurry is coated on the glass layer 10 and cured at a temperature of 90 °C for 30 min to form a photochromic layer.

[0097] In some embodiments, after being irradiated with light, the photochromic layer can change between colorless and dark colors. The dark color can be, but is not limited to, at least one of dark blue / black / dark purple / dark green, etc.

[0098] Optionally, the photochromic layer can withstand weathering at 200 °C for 30 min. The photochromic layer can change color after being irradiated with visible light for 1 min.

[0099] Optionally, in the photochromic layer, the mass fraction of the organic color-changing molecule is 5% to 7%, so that the haze of the functional layer 20 before color change is ≤ 3%, and the transmittance is ≥ 75%.

[0100] Exemplarily, in the absence of light or when the light is weak, the photochromic layer is in a transparent or light color state, and its light transmittance can reach more than 75%. As the intensity of the light irradiation increases, the photochromic layer changes color under the action of visible light. The stronger the intensity, the darker the color, and the light transmittance of the photochromic layer gradually decreases to 23%. It can adjust the light transmittance according to the light intensity, which can give the driver and passengers a good riding experience and also increase the riding safety.

[0101] It can be understood that the light transmittance of the photochromic layer can be adjusted between less than or equal to 23% and greater than or equal to 75%.

[0102] In some other embodiments, the color-changing layer is an electrochromic layer. Specifically, when the light intensity is less than or equal to a preset value, the electrochromic layer has a first light transmittance; when the light intensity is greater than the preset value, a voltage is applied to the electrochromic layer to cause the electrochromic layer to change color and have a second light transmittance, where the first light transmittance is greater than the second light transmittance. For example, when the light intensity is less than or equal to the preset value, the electrochromic layer is transparent; when the light intensity is greater than the preset value, a voltage is applied to the electrochromic layer, and the color of the electrochromic layer becomes darker and the light transmittance decreases.

[0103] In some embodiments, when the functional layer 20 includes a dimming layer or an electrochromic layer, the functional layer 20 includes a first substrate layer (not shown in the figure), a first conductive layer (not shown in the figure), a dimming layer or an electrochromic layer (not shown in the figure), a second conductive layer (not shown in the figure), and a second substrate layer (not shown in the figure) that are sequentially stacked. The first substrate layer is used to carry the first conductive layer, the second substrate layer is used to carry the second conductive layer, and the first conductive layer and the second conductive layer cooperate to apply an electrical signal (such as a voltage signal, a current signal, or an electric field signal, etc.) to cause the molecules of the dimming film to change in orientation, the transparency or haze to change, or the color of the color-changing film to change, thereby changing the light transmittance of the functional layer 20 and further changing the light transmittance of the glass plate 100.

[0104] Optionally, the first substrate layer can be, but is not limited to, polyethylene terephthalate (PET layer), polycarbonate (PC layer), etc. The second substrate layer can be, but is not limited to, polyethylene terephthalate (PET layer), polycarbonate (PC layer), etc.

[0105] Optionally, the first conductive layer can be, but is not limited to, a transparent conductive layer such as indium tin oxide (ITO layer). The second conductive layer can be, but is not limited to, a transparent conductive layer such as indium tin oxide (ITO layer).

[0106] Optionally, the dimming layer may include, but is not limited to, a self-suspended particle device (SPD), polymer dispersed liquid crystal (PDLC), polymer network liquid crystal (PNLC), guest-host liquid crystal, photochromic substance, electrochromic substance, and electrokinetic substance, etc.

[0107] It should be noted that when the color-changing layer is a photochromic layer, the glass plate 100 can be used in conjunction with a light sensor. The light sensor receives the ambient light signal and determines whether to apply a voltage to the photochromic layer based on the ambient light signal detected by the light sensor, so as to adjust the color and light transmittance of the photochromic layer.

[0108] In this embodiment, the color-changing layer is a photochromic layer or an electrochromic layer. When the glass plate 100 is applied as the front windshield of the vehicle 300, the functional layer 20 can change its own color with the change of light intensity, so that the driver can avoid the irradiation of high-angle dazzling sunlight during daytime driving, and when the light is dim on cloudy days, avoid the functional layer 20 being dark when looking up, which causes a depressing environment inside the vehicle, thus bringing a better driving experience to the driver. In addition, the self-cleaning layer 30 is an antistatic layer, so that dust is not easily adsorbed on the surface of the glass plate 100, avoiding the long-term accumulation of dust on the surface of the front windshield, and thus forming a layer of fog shadow on the inner surface of the glass, which affects the driver's observation of the road and traffic.

[0109] Optionally, the functional layer 20 and the self-cleaning layer 30 can be formed by one or more of spraying method, wiping method, flow coating method, brushing method or dipping method, etc. Among them, the functional layer 20 is first sprayed on the surface of the glass layer 10. After the functional layer 20 is formed, the self-cleaning layer 30 is formed by spraying method in the area of the functional layer 20 and the glass layer 10.

[0110] Optionally, the heat-insulating layer may include, but is not limited to, a silver layer. The sound-insulating layer may be, but is not limited to, a polyvinyl butyral layer (PVB layer).

[0111] Optionally, the display layer may be, but is not limited to, one or more of a liquid crystal display layer, a light-emitting diode display layer (LED display layer), a micro light-emitting diode display layer (Micro LED display layer), a mini light-emitting diode display layer (Mini LED display layer), an organic light-emitting diode display layer (OLED display layer), etc.

It can be understood that in this embodiment, the outer glass plate 210, the adhesive layer 220, the glass layer 10, the functional layer 20, and the self-cleaning layer 30 are sequentially stacked.

[0119] As Figure 7As shown, in some other embodiments, the adhesive layer 220 has two layers. The functional layer 20 and the self-cleaning layer 30 are respectively disposed on opposite sides of the glass layer 10. The functional layer 20 is disposed on the side of the glass layer 10 facing the outer glass plate 210 and is located between the two adhesive layers 220, and the self-cleaning layer 30 is disposed on the side of the inner glass plate 230 facing away from the outer glass plate 210.

[0120] In this embodiment, the laminated glass 200 includes an outer glass plate 210, an adhesive layer 220, and an inner glass plate 230. The adhesive layer 220 is disposed between the outer glass plate 210 and the inner glass plate 230 to connect the outer glass plate 210 and the inner glass plate 230, improving the mechanical strength of the glass. At the same time, by providing the adhesive layer 220, part of the ultraviolet light can be filtered out, improving the driving experience of the driver.
