Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass products, in particular to a vehicle window glass and a vehicle. BACKGROUND

[0002] With the popularization of intelligent and networked technologies of automobiles, the number of cameras required by vehicles has developed from one to two, three or even more, and the requirements for the image clarity and position accuracy of the photographed objects have also been greatly improved. These cameras located in the vehicle need to obtain the real-time view of the vehicle during driving through the vehicle window glass, therefore, the optical transmission area in the vehicle window glass for the camera to obtain the outside view of the vehicle needs to have a high enough optical quality, such as a high visible light transmittance, a low diopter, etc.

[0003] Among them, the diopter reflects the maximum allowed light distortion value of the optical transmission area. In order to realize the functions of advanced auxiliary driving and even automatic driving, more and more automobile manufacturers require the design of the diopter of the optical transmission area to be not more than 150 mdpt, and even some require it to be not more than 100 mdpt. It is almost impossible for traditional vehicle window glass to achieve such a low level of optical distortion, because the traditional vehicle window glass uses ceramic ink to print around the optical transmission area, and the optical transmission area is not printed with ceramic ink. The thermal conductivity of the ceramic ink layer is greater than that of the glass, so that the ceramic ink cools and solidifies preferentially to the glass during the subsequent bending forming process above 560℃, and then the solidified ceramic ink exerts stress on the glass, causing light distortion around the junction between the area printed with ceramic ink and the area without ceramic ink, etc. Finally, the diopter of the optical transmission area surrounded by the ceramic ink may be greater than 400 mdpt. SUMMARY

[0004] The purpose of the present application is to provide a vehicle window glass and a vehicle, so that the diopter of the optical transmission area of the vehicle window glass can meet the use requirements of high-precision sensors, and effectively improve the accuracy of image data obtained by the sensors.

[0005] The first aspect of the present application provides a vehicle window glass, comprising a first glass sheet, a second glass sheet and an intermediate layer, the intermediate layer being arranged between the first glass sheet and the second glass sheet in the thickness direction of the vehicle window glass, the vehicle window glass comprising a non-ink area and an optical transmission area, the non-ink area at least surrounding part of the optical transmission area, the non-ink area being connected to the edge of the optical transmission area.

[0006] The non-ink area has a haze H1, and the H1≥10%.

[0007] It is understandable that by achieving high haze in the non-ink areas of the car window glass—that is, a haze of 10% or greater—a masking effect can be achieved in these areas. This eliminates the need to print ceramic ink into the non-ink areas to create a masking effect. It also avoids the stress exerted on the glass by the cured ceramic ink layer during the window glass bending process, which could lead to significant optical distortion in the optical transmission area. Therefore, it helps reduce the refractive power of the optical transmission area, ensuring that its refractive power meets the requirements of high-precision sensors, thereby improving the accuracy of the images acquired by the sensor through the optical transmission area.

[0023] In a possible implementation, the third portion of the first glass plate is ground glass, and the surface of the third portion of the first glass plate is processed by a process such as frosting, sandblasting, film forming, or acid etching.

[0024] In a possible implementation, the vehicle window glass further includes a haze layer, and the haze layer completely covers the non-ink region in the thickness direction of the vehicle window glass.

DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0050] Please refer to Figure 1 , the vehicle window glass 100a in the prior art adopts ceramic ink printing to surround the periphery of the optical transmission area A, and the optical transmission area A is not printed with ceramic ink. The ceramic ink forms a ceramic ink layer 90a. The thermal conductivity of the ceramic ink layer 90a is greater than that of the glass, so that when the subsequent bending forming process is above 560℃, the ceramic ink layer 90a preferentially cools and solidifies to the glass, and then the solidified ceramic ink layer 90a exerts stress on the glass, so that light distortion and the like appear around the junction between the area printed with ceramic ink and the area without ceramic ink, and finally the refractive power of the optical transmission area A surrounded by the ceramic ink layer 90a can be greater than 400mdpt.

[0051] Based on this, please refer toFigure 2 and Figure 3 The application provides a vehicle window glass 100 and a vehicle 1000, which can make the diopter of the optical transmission area S11 of the vehicle window glass 100 meet the use requirement of the high-precision sensor 200, and effectively improve the accuracy of the sensor 200 in acquiring image data.

[0052] The vehicle 1000 comprises a vehicle body 400, a vehicle window glass 100, a support 300 and a sensor 200. The vehicle window glass 100 comprises an inner surface and an outer surface. The vehicle window glass 100 is connected to the vehicle body 400. The inner surface of the vehicle window glass 100 faces the inside of the vehicle 1000, and the outer surface of the vehicle window glass 100 faces the outside of the vehicle 1000. The support 300 is fixed to the inner surface of the vehicle window glass 100. The sensor 200 is located inside the vehicle 1000. The support 300 carries the sensor 200. The sensor 200 is fixed on the inner surface of the vehicle window glass 100 through the support 300. The detection light emitted / received by the sensor 200 passes through the vehicle window glass 100.

[0053] It should be noted that the vehicle 1000 described in the application can be, but is not limited to, a vehicle such as a car, a train and a rail transit. The vehicle window glass 100 can be, but is not limited to, a front windshield, a side window glass, a rear windshield and a sunroof glass of the vehicle 1000. The sensor 200 can be, but is not limited to, a visible light camera, a near-infrared camera, a thermal imager and a laser radar. The application is only described by taking the vehicle 1000 as a car, the vehicle window glass 100 as a front windshield and the sensor 200 as a visible light camera.

[0054] It can be understood that in order to enhance the function of the sensor 200 or make the sensor 200 more convenient to use, the sensor 200 is usually equipped with accessories around the sensor 200, such as a sensor connector, a signal converter and the like.

[0055] Please refer to FIG. 4(a) and FIG. 4(b) together. The vehicle window glass 100 comprises an information collection area S1 and a non-information collection area S2. The non-information collection area S2 completely surrounds the information collection area S1. The non-information collection area S2 comprises a main view area S21 and a shielding area S22. The shielding area S22 is arranged along the periphery of the vehicle window glass 100. The shielding area S22 is arranged around the periphery of the main view area S21. The visible light transmittance TL3 of the main view area S21 is greater than 70%, or TL3 is less than or equal to 70%, or TL3 is less than or equal to 30%, or TL3 is less than or equal to 10%. It can be understood that when TL3 is greater than 70%, the vehicle window glass 100 is suitable for a front windshield; when TL3 is less than or equal to 70%, the vehicle window glass 100 is suitable for a rear door glass, a rear windshield or a sunroof of the vehicle 1000. The visible light transmittance TL4 of the shielding area S22 is less than or equal to 10%, and / or the haze of the shielding area S22 is greater than or equal to 10%, so as to facilitate the shielding, protection and overall aesthetics. By arranging the ceramic ink layer on the shielding area S22, the visible light transmittance TL4 of the shielding area S22 is less than or equal to 10%; and / or, by making the shielding area S22 have high haze, that is, the haze of the shielding area S22 is greater than or equal to 10%, the shielding effect of the shielding area S22 is achieved.

[0056] The information collection area S1 is located at the top of the vehicle window glass 100, so as to facilitate the sensor 200 to have a better field of view. The shielding area S22 surrounds the information collection area S1. The information collection area S1 is arranged in a staggered manner with the main view area S21. That is, the information collection area S1 and the main view area S21 do not overlap. The information collection area S1 comprises an optical transmission area S11 and a non-ink area S12. The detection light emitted / received by the sensor 200 passes through the optical transmission area S11. The non-ink area S12 can shield the bracket 300 or accessories for installing the sensor 200. The non-ink area S12 is connected with part of the edge of the shielding area S22. The non-ink area S12 at least surrounds part of the optical transmission area S11. The non-ink area S12 is spaced apart from the optical transmission area S11 and the shielding area S22. The distance between the optical transmission area S11 and the shielding area S22 is greater than or equal to 10 mm. Preferably, the distance between the optical transmission area S11 and the shielding area S22 is greater than or equal to 60 mm.

[0057] It is to be noted that the shielding area S22 can be annular in shape identical to the vehicle window glass 100, or the shielding area S22 can partially protrude to the middle portion of the vehicle window glass 100. For example, the non-ink area S12 is connected to the protruding portion of the shielding area S22, or the protruding portion of the shielding area S22 completely surrounds the non-ink area S12. The optical transmission area S11 can be trapezoidal, or rectangular, or elliptical, or triangular, or circular. The shape of the optical transmission area S11 is not limited to the above-mentioned shapes, and can be any shape that meets the requirements of the sensor 200. The present application does not strictly limit the shape of the shielding area S22 and the optical transmission area S11. The present application only illustrates the case that the shielding area S22 does not partially protrude to the middle portion of the vehicle window glass 100.

[0058] In one possible implementation, as shown in FIG. 4(a), the optical transmission area S11 is completely located in the non-ink area S12, and the non-ink area S12 completely surrounds the optical transmission area S11, i.e., 100% of the outline of the optical transmission area S11 is surrounded by the non-ink area S12.

[0059] In another possible implementation, as shown in FIG. 4(b), the outline of the optical transmission area S11 can also be partially surrounded by the non-ink area S12. In order to achieve the best shielding effect, it is preferred that at least 50% of the outline of the optical transmission area S11 is surrounded by the non-ink area S12, or at least 60% of the outline of the optical transmission area S11 is surrounded by the non-ink area S12, or at least 70% of the outline of the optical transmission area S11 is surrounded by the non-ink area S12, or at least 80% of the outline of the optical transmission area S11 is surrounded by the non-ink area S12, or at least 90% of the outline of the optical transmission area S11 is surrounded by the non-ink area S12.

[0060] In the present application, the intersection area of the field of view (FOV) range of the sensor 200 and the vehicle window glass 100 is defined as a detection area. The optical transmission area S11 completely covers the detection area, so as to facilitate the sensor 200 to emit / receive detection light. Preferably, the distance between the edge of the optical transmission area S11 and the edge of the detection area is d, and d is in the range of 1.0 mm≤d≤5.0 mm.

[0061] It can be understood that in some embodiments, a plurality of sensors 200 are installed inside the vehicle 1000, and each of the sensors 200 can be provided with an independent optical transmission area S11. In other embodiments, a plurality of sensors 200 are installed inside the vehicle 1000, and the plurality of sensors 200 share a part of the field of view range, i.e., there is an overlapping area in the field of view range of the plurality of sensors 200, and the shared optical transmission area S11 is arranged according to the field of view range of the plurality of sensors 200 and the overlapping area.

[0062] In the present application, the shielding effect of the non-ink area S12 is achieved by high-haze processing of the non-ink area S12.

[0063] In the present application, the non-ink region S12 has a haze H1. The non-ink region S12 has a haze H1≥10%. Further, the non-ink region S12 has a haze H1≥50%, or H1≥80%, or H1≥90%. The non-ink region S12 has a visible light transmittance TL1. TL1≤80%. Further, TL1≤10%, or TL1≤5%, or TL1≤1%. The non-ink region S12 has an ultraviolet light transmittance T1 UV , T1 UV ≤1%. Further, T1 UV ≤0.1%. The non-ink region S12 has a refractive power less than or equal to 200 mdpt.

[0064] The optically transparent region S11 has a haze H2. The optically transparent region S11 has a haze H2≤10%. Further, the optically transparent region S11 has a haze H2≤5%, or H2≤2%. The optically transparent region S11 has a visible light transmittance TL2. TL2≥70%, or TL2≥80%, or TL2≥90%. The optically transparent region S11 has an ultraviolet light transmittance T2 UV , T2 UV ≤1%. Further, T2 UV ≤0.1%. The optically transparent region S11 has a refractive power less than or equal to 200 mdpt.

[0065] Further, the ratio of the haze H1 of the non-ink region S12 to the haze H2 of the optically transparent region S11 is in the range of 5≤H1 / H2≤48. For example, the ratio of the haze H1 of the non-ink region S12 to the haze H2 of the optically transparent region S11 is 4, or 8, or 16, or 20, or 24, or 28, or 32, or 36, or 40, or 44, or 48, etc.

[0066] In the present application, along the thickness direction of the vehicle window glass 100, the support 300 has a projection on the vehicle window glass 100 at least partially located in the non-ink region S12. The non-ink region S12 can shield at least part of the support 300, so that the observer cannot see the support 300 from the outside of the vehicle 1000, thereby achieving an aesthetic effect.

[0067] Please refer to Figure 5 and Figure 6 , the present application provides a first embodiment of the vehicle window glass 100. In this embodiment, the vehicle window glass 100 comprises a laminated glass 10. By the high haze of the intermediate layer 13 of the laminated glass 10, the high haze of the non-ink region S12 is achieved.

[0068] The laminated glass 10 includes a first glass sheet 11, a second glass sheet 12, and an interlayer 13. The interlayer 13 is disposed between the first glass sheet 11 and the second glass sheet 12. The first glass sheet 11 includes a first surface 111 and a second surface 112. The second surface 112 faces away from the first surface 111. The second surface 112 faces the interlayer 13. The second glass sheet 12 includes a third surface 121 and a fourth surface 122. The third surface 121 faces away from the fourth surface 122. The third surface 121 faces the interlayer 13. The interlayer 13 connects the second surface 112 and the third surface 121. It can be understood that the first glass sheet 11 can be closer to the outside of the vehicle 1000 relative to the second glass sheet 12, or the first glass sheet 11 can be closer to the inside of the vehicle 1000 relative to the second glass sheet 12. The embodiment is described by way of example only with the first glass sheet 11 being closer to the outside of the vehicle 1000 relative to the second glass sheet 12.

In addition, the laminated glass 10 can have the following structure: the laminated glass 10 further includes an outer glass sheet and an additional interlayer 13, and the outer glass sheet is bonded to the first surface 111 of the first glass sheet 11 through the additional interlayer 13 in the thickness direction of the laminated glass 10. In this case, the first glass sheet 11 and the second glass sheet 12 are both inner glass sheets (glass sheets located on the inside of the vehicle 1000). Alternatively, the laminated glass 10 further includes an inner glass sheet and an additional interlayer 13, and the inner glass sheet is bonded to the fourth surface 122 of the second glass sheet 12 through the additional interlayer 13 in the thickness direction of the laminated glass 10.

For example, the thickness of the outer glass sheet can be, but is not limited to, 1.6mm, or 3.2mm, or 4.8mm, or 6.0mm, etc. The visible light transmittance of the outer glass sheet is 1%-99% (including the end point value). For example, the visible light transmittance of the outer glass sheet can be, but is not limited to, 1%, 2%, or 10%, or 20%, or 30%, or 40%, or 50%, or 60%, or 70%, or 80%, or 90%, or 99%, etc. The outer glass sheet can be inorganic glass or organic glass. The material of the outer glass sheet can be, but is not limited to, soda-lime glass, borosilicate glass, alumino-silicate glass, polymethyl acrylate, polycarbonate, etc. Further, the material of the outer glass sheet is soda-lime glass.

[0071] The inner glass sheet is transparent or colored glass. The thickness of the inner glass sheet is 0.7mm-6.0mm (including the end point value). For example, the thickness of the inner glass sheet can be, but is not limited to, 0.7mm, or 1.4mm, or 2.1mm, or 2.8mm, or 3.5mm, or 4.2mm, or 4.9mm, or 5.6mm, or 6.0mm, etc. The visible light transmittance of the inner glass sheet is 1%-99% (including the end point value). For example, the visible light transmittance of the inner glass sheet can be, but is not limited to, 1%, 2%, or 10%, or 20%, or 30%, or 40%, or 50%, or 60%, or 70%, or 80%, or 90%, or 99%, etc. The inner glass sheet can be inorganic glass or organic glass. The material of the inner glass sheet can be, but is not limited to, soda-lime glass, borosilicate glass, alumino-silicate glass, polymethyl acrylate, polycarbonate, etc. Further, the material of the inner glass sheet is soda-lime glass.

[0072] In this embodiment, the intermediate layer 13 includes at least one adhesive layer 133. The adhesive layer 133 is a transparent thermoplastic polymer film or a colored thermoplastic polymer film. The thickness of the adhesive layer 133 is 0.38 mm to 1.52 mm (inclusive of endpoint values). For example, the thickness of the adhesive layer 133 can be, but is not limited to, 0.38 mm, 0.76 mm, 1.14 mm, or 1.52 mm. Further, the thickness of the adhesive layer 133 is 0.76 mm.

The thermoplastic polymer film can be made of at least one material selected from polyvinyl butyral (PVB), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), polycarbonate (PC), polymethyl methacrylate (PMMA), and ionic polymer (SentryGlasPlus, SGP). The adhesive layer 133 blocks ultraviolet light transmission. The adhesive layer 133 has an ultraviolet transmittance T0. UV T UV ≤1%. For example, T0 UV It can be, but is not limited to, 1%, 0.8%, 0.6%, 0.4%, or 0.2%, etc. Furthermore, T UV ≤0.1%.

[0073] The adhesive layer 133 includes a first part, a second part, and a third part. The first part of the adhesive layer 133 at least partially surrounds the second part. The edges of the first part and the second part are connected. The third part completely surrounds the first part and the second part.

[0074] One possible implementation, such as Figure 5 The intermediate layer 13 is a single-layer structure. The intermediate layer 13 includes an adhesive layer 133. The first part of the adhesive layer 133 is also the first portion 131 of the intermediate layer 13, and the second part of the adhesive layer 133 is also the second portion 132 of the intermediate layer 13. The third part of the adhesive layer 133 is also the seventh portion 137 of the intermediate layer 13. It can be understood that the intermediate layer 13 includes the first portion 131, the second portion 132, and the seventh portion 137. The first portion 131 at least partially surrounds the second portion 132, and the edges of the first portion 131 and the second portion 132 are connected. The haze of the first portion 131 is greater than that of the second portion 132. The seventh portion 137 completely surrounds the first portion 131 and the second portion 132.

[0075] In another possible implementation, the intermediate layer 13 is a multi-layer structure. The intermediate layer 13 includes a plurality of adhesive layers 133. The plurality of adhesive layers 133 are sequentially stacked along the thickness direction of the vehicle window glass 100. Specifically, the first portions of the plurality of adhesive layers 133 are overlapped with each other, and the first portions of the plurality of adhesive layers 133 are stacked to form the first portion 131 of the intermediate layer 13. The second portions of the plurality of adhesive layers 133 are overlapped with each other, and the second portions of the plurality of adhesive layers 133 are stacked to form the second portion 132 of the intermediate layer 13. The third portions of the plurality of adhesive layers 133 are overlapped with each other, and the third portions of the plurality of adhesive layers 133 are stacked to form the seventh portion 137 of the intermediate layer 13. It can be understood that the intermediate layer 13 includes the first portion 131, the second portion 132, and the seventh portion 137, the first portion 131 surrounds the second portion 132, and the edges of the first portion 131 and the second portion 132 are connected. The haze of the first portion 131 is greater than the haze of the second portion 132. The seventh portion 137 completely surrounds the first portion 131 and the second portion 132.

[0076] It should be noted that the first portion 131, the second portion 132, and the seventh portion 137 of the intermediate layer 13 are only regional divisions of the entire intermediate layer 13, and are not mandatory limitations that the first portion 131, the second portion 132, and the seventh portion 137 need to be three relatively independent individuals, i.e., the first portion 131, the second portion 132, and the seventh portion 137 can be integrally formed structures or structures formed by other means, which are not limited by the present application. Figure 5 and Figure 6 The dashed lines in the above two figures are only used to divide the first portion 131, the second portion 132, and the seventh portion 137 of the intermediate layer 13, and do not limit the specific structure of the laminated glass 10.

[0077] Please continue to refer to Figure 5 and Figure 6 In the embodiment, the first glass plate 11 and the second glass plate 12 are connected by the intermediate layer 13. Along the thickness direction of the vehicle window glass 100, the first portion 131 of the intermediate layer 13 completely overlaps the non-ink area S12. The second portion 132 completely overlaps the optical transmission area S11. The seventh portion 137 completely overlaps the non-information acquisition area S2. In one possible implementation, as shown in Figure 5 , the non-ink area S12 completely surrounds the optical transmission area S11, and the first portion 131 completely surrounds the second portion 132. In another possible implementation, as shown in Figure 6 , the non-ink area S12 surrounds part of the optical transmission area S11, and the first portion 131 surrounds part of the second portion 132.

[0078] The non-ink area S12 of the vehicle window glass 100 has high haze by making the partial laminated glass 10 have high haze. The haze of the first part 131 of the interlayer 13 is greater than or equal to 10%. Specifically, when the interlayer 13 is a single-layer structure, the haze of the first part of the single adhesive layer 133 is greater than or equal to 10%. When the interlayer 13 is a multi-layer structure, the haze of the first part of at least one adhesive layer 133 is greater than or equal to 10%.

[0079] It should be noted that colorant particles can be added to the first part of the adhesive layer 133 to increase the scattering of light by the colorant particles, thereby increasing the haze of the first part of the adhesive layer 133. For example, the first part of the adhesive layer 133 includes a matrix and colorant particles, and the colorant particles are uniformly distributed in the matrix. The matrix is PVB, EVA, PU, PC, PMMA or SGP, and the colorant particles are CaCO3, CaSO4, MgSO4, MgO, ZnSO4 or ZnO.

[0080] It can be understood that by making the haze of the first part 131 of the interlayer 13 greater than or equal to 10%, the first part 131 completely coincides with the non-ink area S12, which can make the non-ink area S12 have high haze, that is, the haze H1 of the non-ink area S12 is greater than or equal to 10%, achieving the shielding effect of the non-ink area S12 of the vehicle window glass 100. Thus, there is no need to provide a ceramic ink layer in the non-ink area S12, avoiding the stress of the solidified ceramic ink layer on the glass during the bending forming process of the vehicle window glass 100, resulting in obvious light distortion in the optical transmission area S11. Thus, it is beneficial to reduce the diopter of the optical transmission area S11, so that the diopter of the optical transmission area S11 can meet the use requirements of high-precision sensors, thereby improving the accuracy of the image obtained by the sensor 200 through the optical transmission area S11.

[0081] The first glass plate 11 and the second glass plate 12 are bonded by the interlayer 13 after the first glass plate 11 and the second glass plate 12 have undergone a bending forming process, so the interlayer 13 does not need to undergo high-temperature treatment in the bending forming process, and the optical performance of the interlayer 13 is stable, and thus the optical performance of the vehicle window glass 100 is stable.

[0082] It should be noted that the haze of the first portion 131 of the intermediate layer 13 in the embodiment is greater than or equal to 10%, so that the non-ink area S12 of the vehicle window glass 100 has high haze, and the shielding effect of the non-ink area S12 is achieved, so as to replace the scheme of arranging ceramic ink in the non-ink area S12 and ensure the structural strength of the vehicle window glass 100. The non-ink area S12 can be arranged without an ink layer or can be arranged with an ink layer. The proportion of the ink layer in the non-ink area S12 to the range of the non-ink area S12 is less than or equal to 10%. For example, the ink layer in the non-ink area S12 can be used to mark the vehicle window glass 100.

[0083] In the embodiment, the vehicle window glass 100 further comprises a heat insulation layer (not shown in the figure) and a low-emissivity layer (not shown in the figure). The heat insulation layer is used to adjust the heat insulation performance of the vehicle window glass 100. The low-emissivity layer is used to adjust the radiation performance of the vehicle window glass 100. The heat insulation layer and the low-emissivity layer can be arranged on the first surface 111, the second surface 112, the third surface 121 or the fourth surface 122 of the laminated glass 10. The heat insulation layer and the low-emissivity layer are respectively arranged on different surfaces of the laminated glass 10. For example, the heat insulation layer is laminated on the second surface 112 of the first glass sheet 11. The low-emissivity layer is laminated on the fourth surface 122 of the second glass sheet 12. Along the thickness direction of the vehicle window glass 100, the heat insulation layer completely covers the main view area S21. Along the thickness direction of the vehicle window glass 100, the low-emissivity layer completely covers the main view area S21.

[0084] In other embodiments, the vehicle window glass 100 can also not be provided with a heat insulation layer or a low-emissivity layer.

[0085] The heat insulation layer comprises a functional metal layer and a plurality of dielectric layers. Along the thickness direction of the heat insulation layer, the functional metal layer is laminated with dielectric layers on both sides. The number of functional metal layers can be one or more. The functional metal layer and the dielectric layer can be deposited by a chemical vapor deposition (CVD) or a physical vapor deposition (PVD) method. For example, the functional metal layer and the dielectric layer are deposited by a magnetron sputtering method.

[0086] The functional metal layer can be a metal layer or an alloy layer. For example, the material of the functional metal layer can be a metal or a metal alloy selected from at least one element of Ag, Au, Cu, Al, Pt. The material of the dielectric layer can be at least one of a nitride, an oxide and an oxynitride of a metal selected from Zn, Sn, Ti, Si, Al, Ni, Cr, Nb, Mg, Zr, Ga, Y, In, Sb, V, Ta and an alloy thereof.

[0087] The emissivity E of the low-emissivity layer is ≤ 0.3. The low-emissivity layer comprises at least one dielectric layer. The dielectric layer can be deposited by a Chemical Vapor Deposition (CVD) or a Physical Vapor Deposition (PVD) method. Exemplarily, the dielectric layer is deposited by magnetron sputtering.

[0088] The material of the dielectric layer can be at least one selected from the group consisting of nitrides, oxides, oxynitrides of Zn, Sn, Ti, Si, Al, Ni, Cr, Nb, Mg, Zr, Ga, Y, In, Sb, V, Ta and alloys thereof.

[0089] Referring to Figure 7 and Figure 8 , a second embodiment of the vehicle window glass 100 is provided. The difference between this embodiment and the first embodiment described above is that the vehicle window glass 100 has high haze by the first glass sheet 11, and realizes high haze in the non-ink area S12.

[0090] In this embodiment, the first glass sheet 11 comprises a third portion 113, a fourth portion 114, and an eighth portion 118. The third portion 113 at least surrounds part of the fourth portion 114. The third portion 113 is connected to the edge of the fourth portion 114. The eighth portion 118 completely surrounds the third portion 113 and the fourth portion 114. Among them, the third portion 113, the fourth portion 114, and the eighth portion 118 of the first glass sheet 11 are only regional divisions of the entire first glass sheet 11, and are not mandatory to limit that the third portion 113, the fourth portion 114, and the eighth portion 118 need to be three relatively independent individuals, that is, the third portion 113, the fourth portion 114, and the eighth portion 118 can be a structure integrally formed, or can be a structure formed by splicing in other ways, which is not limited in the present application.

[0091] In this embodiment, the second glass sheet 12 comprises a fifth portion 125, a sixth portion 126, and a ninth portion 129. The fifth portion 125 at least surrounds part of the sixth portion 126. The fifth portion 125 is connected to the edge of the sixth portion 126. The ninth portion 129 completely surrounds the fifth portion 125 and the sixth portion 126. Among them, the fifth portion 125, the sixth portion 126, and the ninth portion 129 of the second glass sheet 12 are only regional divisions of the entire first glass sheet 11, and are not mandatory to limit that the fifth portion 125, the sixth portion 126, and the ninth portion 129 need to be three relatively independent individuals, that is, the fifth portion 125, the sixth portion 126, and the ninth portion 129 can be a structure integrally formed, or can be a structure formed by splicing in other ways, which is not limited in the present application.

[0092] It should be noted that,Figure 7 and Figure 8 The dashed lines are only used to divide the third part 113, the fourth part 114 and the eighth part 118 of the first glass plate 11, and the fifth part 125, the sixth part 126 and the ninth part 129 of the second glass plate 12. They do not constitute a limitation on the specific structure of the laminated glass 10.

[0093] In this embodiment, the first glass plate 11 and the second glass plate 12 are bonded together via an intermediate layer 13. Along the thickness direction of the window glass 100, the third portion 113 of the first glass plate 11 and the fifth portion 125 of the second glass plate 12 completely overlap with the non-ink area S12. The fourth portion 114 of the first glass plate 11 and the sixth portion 126 of the second glass plate 12 completely overlap with the optical transmission area S11. The eighth portion 118 of the first glass plate 11 and the ninth portion 129 of the second glass plate 12 completely overlap with the non-information acquisition area S2. In one possible implementation, as... Figure 7 The non-ink area S12 completely surrounds the optically transparent area S11, and the third portion 113 of the first glass plate 11 completely surrounds the fourth portion 114. The fifth portion 125 of the second glass plate 12 completely surrounds the sixth portion 126. Another possible implementation is as follows... Figure 8 The non-ink area S12 surrounds the optically transparent area S11, the third portion 113 of the first glass plate 11 surrounds the fourth portion 114, and the fifth portion 125 of the second glass plate 12 surrounds the sixth portion 126.

[0094] High haze is achieved in the non-ink area S12 of the vehicle window glass 100 by locally applying high haze to the laminated glass 10. The haze of the third portion 113 of the first glass plate 11 is greater than or equal to 10%. Further, the ratio of the haze H3 of the third portion 113 to the haze H4 of the fourth portion 114 of the first glass plate 11 is in the range of 25 ≤ H3 / H4 ≤ 80. For example, the ratio of the haze H3 of the third portion 113 to the haze H4 of the fourth portion 114 is 25, 50, 75, or 80, etc. In other embodiments, the haze of the fifth portion 125 of the second glass plate 12 may also be greater than or equal to 10%. Further, the ratio of the haze H5 of the fifth portion 125 of the second glass plate 12 to the haze H6 of the sixth portion 126 is in the range of 25 ≤ H5 / H6 ≤ 80. For example, the ratio of haze H5 in Part 5 125 to haze H6 in Part 6 126 is 25, or 50, or 75, or 80, etc.

[0095] It should be noted that the third part 113 of the first glass sheet 11 can be subjected to a surface treatment process to form the third part 113 of the first glass sheet 11 into frosted glass, thereby increasing the haze of the third part 113 of the first glass sheet 11. Frosted glass is a kind of glass product with a special treatment to make the glass surface appear blurred, frosted or milky white. The surface treatment process includes acid etching process, sanding process, sand blasting process and film forming process, etc. Among them, the acid etching process is to immerse the glass in an acidic solution, and the glass surface is corroded by the acid to produce a frosted effect. The sanding process is to use grinding tools (such as grinding wheels, sand wheels) to mechanically sand the glass surface, so that the glass surface becomes blurred. The sand blasting process is to use high-pressure airflow to spray sand particles to the glass surface, thereby sanding the glass surface. The film forming process is to coat a special translucent film or frosted film on the glass surface to make it appear frosted. It can be understood that to increase the haze of the fifth part 125 of the second glass sheet 12, the surface treatment process of the third part 113 of the first glass sheet 11 can also be referred to.

[0096] It can be understood that by making the haze of the third part 113 of the first glass sheet 11 greater than or equal to 10%, the third part 113 completely coincides with the non-ink area S12, which can make the non-ink area S12 of the vehicle window glass 100 have a high haze, that is, the haze H1 of the non-ink area S12 is greater than or equal to 10%, and the shielding effect of the non-ink area S12 of the vehicle window glass 100 is achieved. Thus, there is no need to print ceramic ink on the non-ink area S12 of the vehicle window glass 100 to form a shielding effect, avoiding the stress of the cured ceramic ink layer on the glass during the bending and molding process of the vehicle window glass 100, resulting in obvious optical distortion of the optical transmission area S11. Thus, it is beneficial to reduce the diopter of the optical transmission area S11, so that the diopter of the optical transmission area S11 can meet the use requirements of high-precision sensors, thereby improving the accuracy of the image obtained by the sensor 200 through the optical transmission area S11. It can be understood that the vehicle window glass 100 can also be combined with the intermediate layer 13 to achieve the shielding effect of the non-ink area S12. The setting mode of the intermediate layer 13 can refer to the first embodiment described above. Herein, no more details are given.

[0097] Please refer to Figure 9 , the present application provides a third embodiment of the vehicle window glass 100. The difference between this embodiment and the first embodiment described above is that the vehicle window glass 100 further comprises a haze layer. By having a high haze, the haze layer achieves the shielding effect of the non-ink area S12.

[0098] In this embodiment, the haze layer is the light control film 40. The haze of the light control film 40 can be greater than or equal to 10%. The types of the light control film 40 include, but are not limited to, polymer dispersed liquid crystal (PDLC), polymer network liquid crystal (PNLC), guest / host liquid crystal (GHLC), electrochromic (EC), etc. The haze of the light control film 40 has a minimum value and a maximum value. By adjusting the power-on voltage of the light control film 40, the haze of the light control film 40 can be changed. When the light control film 40 is powered on, the haze of the light control film 40 increases from the minimum value; as the voltage increases, the haze of the light control film 40 increases; when the voltage increases to a critical value, the haze of the light control film 40 reaches the maximum value; when the light control film 40 is powered off, the haze of the light control film 40 decreases to the minimum value; or, when the light control film 40 is powered on, the haze of the light control film 40 decreases from the maximum value; as the voltage increases, the haze of the light control film 40 decreases; when the voltage increases to a critical value, the haze of the light control film 40 reaches the minimum value; when the light control film 40 is powered off, the haze of the light control film 40 increases to the maximum value.

[0099] It should be noted that the number of light control films 40 can be one or more. The number of light control films 40 is one in the embodiments of the present application.

[0100] In this embodiment, the intermediate layer 13 is a multi-layer structure. The intermediate layer 13 includes a plurality of adhesion layers 133 stacked in sequence. The thickness, material and structure of the adhesion layer 133 can be referred to the related description of the adhesion layer 133 in the first embodiment described above. Herein, no more description is made.

[0101] In this embodiment, the plurality of adhesion layers 133 are arranged in sequence along the thickness direction of the vehicle window glass 100. The light control film 40 is arranged between any two adhesion layers 133 along the thickness direction of the vehicle window glass 100. The light control film 40 completely covers the non-ink area S12. It can be understood that the light control film 40 can also cover at least part of the main viewing area S21 and / or the shading area S22.

[0102] It should be noted that, Figure 9The number of the adhesive layers 133 and the clamping position of the dimming film 40 in the second embodiment are only used for the structural schematic of the plurality of adhesive layers 133 and the dimming film 40, the adhesive layers 133 can also be other numbers, and the dimming film 40 can also be clamped between any other two adhesive layers 133, which does not form a specific limitation on the number of the adhesive layers 133 and the clamping position of the dimming film 40. In FIG. 4, only the dimming film 40 completely covers the non-ink area S12 and the non-information collection area S2, and the non-ink area S12 completely surrounds the optical transmission area S11 are taken as examples for illustration, which does not form a specific limitation on the coverage range of the dimming film 40 and the positional relationship between the non-ink area S12 and the optical transmission area S11.

[0103] It can be understood that, in the second embodiment, by clamping the dimming film 40 between any two adhesive layers 133 of the intermediate layer 13 and making the dimming film 40 completely cover the non-ink area S12, the haze of the dimming film 40 can be adjusted by adjusting the voltage applied to the dimming film 40, so that the haze of the dimming film 40 is greater than or equal to 10%, and thus the non-ink area S12 of the vehicle window glass 100 has high haze, that is, the haze H1 of the non-ink area S12 is greater than or equal to 10%. Thus, it is not necessary to print ceramic ink on the non-ink area S12 of the vehicle window glass 100 to form a shielding effect, which avoids that the cured ceramic ink layer exerts stress on the glass during the bending forming process of the vehicle window glass 100, resulting in obvious optical distortion of the optical transmission area S11. Therefore, it is beneficial to reduce the diopter of the optical transmission area S11, so that the diopter of the optical transmission area S11 can meet the use requirements of high-precision sensors, and thus the accuracy of the image obtained by the sensor 200 through the optical transmission area S11 is improved.

[0104] In addition, the dimming film 40 covers at least part of the main viewing area S21, and by adjusting the haze of the dimming film 40, the haze of the main viewing area S21 of the vehicle window glass 100 can also be adjusted, so that the vehicle window glass 100 can be applied to different application scenarios.

[0105] The dimming film 40 is clamped between two adhesive layers 133 after the first glass plate 11 and the second glass plate 12 are subjected to the bending forming process, so that the dimming film 40 does not need to be subjected to high-temperature heat treatment, and the optical performance of the dimming film 40 is more stable.

[0106] It can be understood that, in the second embodiment, the vehicle window glass 100 can also realize the shielding effect of the non-ink area S12 in combination with the intermediate layer 13 and / or the first glass plate 11. The setting mode of the intermediate layer 13 can refer to the first embodiment described above. The setting mode of the first glass plate 11 can refer to the second embodiment described above. Herein, no more details are described.

[0107] Please refer to Figure 10The fourth embodiment of the vehicle window glass 100 is provided. The difference between this embodiment and the first embodiment described above is that the vehicle window glass 100 further includes a haze layer. By the haze layer having a high haze, a high haze of the non-ink area S12 is achieved.

[0108] In this embodiment, the haze layer is the functional layer 50. The haze of the functional layer 50 is constant. The haze of the functional layer 50 is greater than or equal to 10%. The functional layer 50 can be a film layer having a heat insulation, low radiation, or the like, or can be a film layer not having a heat insulation, low radiation, or the like. For example, the functional layer 50 is a film layer having a heat insulation or low radiation function, and the functional layer 50 achieves a haze greater than or equal to 10% and a heat insulation effect or low radiation effect by a film structure.

[0109] In this embodiment, the material of the functional layer 50 can be an inorganic material. For example, the functional layer 50 is formed by stacking a plurality of dielectric layers. The material of the dielectric layer can be at least one selected from the group consisting of nitrides, oxides, and oxynitrides of Zn, Sn, Ti, Si, Al, Ni, Cr, Nb, Mg, Zr, Ga, Y, In, Sb, V, Ta, and alloys thereof.

[0110] The material of the functional layer 50 can also be an organic material. The material of the functional layer 50 includes, but is not limited to, one or more of polybutylene terephthalate (PBT), polymerized styrene butadiene rubber (SBR), poly(ether-ether-ketone) (PEEK), ethylene propylene diene monomer (EPDM), butyl rubber (IIR, isobutylene isoprene rubber), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), nitrile butadiene rubber (NBR), polymethyl methacrylate (PMMA), acrylonitrile butadiene styrene plastic (ABS), polycarbonate (PC), polyamide, polyformaldehyde (POM), polyethylene glycol terephthalate (PET), modified polyphenylene oxide (MPPO), fluoroplastic, polyimide (PI), polyphenylene sulfide (PPS), polysulfone (PSU), and polyethylene (PE).

[0111] The functional layer 50 can be deposited by a chemical vapor deposition (CVD) or a physical vapor deposition (PVD) method.

[0112] In the present embodiment, at least one of the first surface 111, the second surface 112, the third surface 121, or the fourth surface 122 of the laminated glass 10 is provided with the functional layer 50. The functional layer 50 completely covers the non-ink region S12. It can be understood that the functional layer 50 can also cover at least part of the main viewing region S21 and / or the obscuration region S22. When the material of the functional layer 50 is an organic material, the functional layer 50 is preferably provided on the fourth surface 122 of the laminated glass 10.

[0113] It should be noted that, Figure 10 For example, the fourth surface 122 of the laminated glass 10 is provided with the functional layer 50, the functional layer 50 completely covers the non-ink area S12, and the non-ink area S12 completely surrounds the optical transmission area S11, which does not form a specific limitation on the position of the functional layer 50, the coverage range, and the positional relationship between the non-ink area S12 and the optical transmission area S11.

[0114] It can be understood that, in the embodiment, by providing the functional layer 50 and the functional layer 50 completely covering the non-ink area S12, the haze of the functional layer 50 is greater than or equal to 10%, which can make the non-ink area S12 of the vehicle window glass 100 have high haze, that is, the haze H1 of the non-ink area S12 is greater than or equal to 10%. Thus, it is not necessary to print ceramic ink on the non-ink area S12 of the vehicle window glass 100 to form a shielding effect, avoiding that the cured ceramic ink layer exerts stress on the glass during the bending forming process of the vehicle window glass 100, resulting in obvious light distortion of the optical transmission area S11. Thus, it is beneficial to reduce the diopter of the optical transmission area S11, so that the diopter of the optical transmission area S11 can meet the use requirements of high-precision sensors, thereby improving the accuracy of the image obtained by the sensor 200 through the optical transmission area S11.

[0115] In addition, the functional layer 50 can simultaneously have heat insulation or low radiation effect, which can realize high haze of the non-ink area S12 of the vehicle window glass 100, and also realize heat insulation or low radiation effect of the non-ink area S12. Especially when the functional layer 50 covers at least part of the main viewing area S21, the heat insulation or low radiation effect of the main viewing area S21 can also be realized.

[0116] The thickness of the functional layer 50 is relatively thin, so that even if the functional layer 50 is attached to the first glass plate 11 or the second glass plate 12 and passes through the bending forming process, the functional layer 50 is not sufficient to exert stress on the glass plate, so that the optical transmission area S11 of the glass plate has obvious light distortion. Especially when the functional layer 50 is an organic material, the functional layer 50 is arranged on the fourth surface 122 of the laminated glass 10, and the functional layer 50 can be arranged after the bending forming process of the second glass plate 12. Thus, the functional layer 50 does not need to undergo high-temperature treatment of the bending forming process, and the optical performance of the functional layer 50 is stable, and the optical performance of the vehicle window glass 100 is stable.

[0117] It can be understood that in the embodiment, the vehicle window glass 100 can also realize the shielding effect of the non-ink area S12 in combination with the intermediate layer 13 and / or the first glass plate 11 and / or the light-adjustable film 40. The arrangement mode of the intermediate layer 13 can refer to the first embodiment described above. The arrangement mode of the first glass plate 11 can refer to the second embodiment described above. The arrangement mode of the light-adjustable film 40 can refer to the third embodiment described above. Details are not described herein.
