[0004] With the advancement of smart driving vehicles, there is a growing demand for applications that install detectors inside the vehicle, and insulating glass is increasingly being chosen for car windows.

It is evident that the described embodiments are merely some embodiments of the present application and not all embodiments. All other embodiments obtained by a person skilled in the art without creative effort based on the embodiments of the present application fall within the scope of protection of the present application.

Those skilled in the art may understand, either explicitly or implicitly, that the Examples described herein may be combined with other Examples.

[0032] Referring to FIG. 1, FIG. 1 is a schematic diagram of a laminated glass assembly provided in one embodiment of the present application. The present application provides a laminated glass assembly (100). The laminated glass assembly (100) comprises laminated glass (110), a wave-transparent layer (120), and an insulating layer (130). The laminated glass (110) has a signal transmission area (Q1) and a non-signal transmission area (Q2). The wave-transparent layer (120) is mounted on the laminated glass (110), and the orthographic projection of the wave-transparent layer (120) on the laminated glass (110) covers the signal transmission area (Q1) and the non-signal transmission area (Q2). The insulation layer (130) is mounted on the laminated glass (110), and the orthographic projection of the insulation layer (130) on the laminated glass (110) covers the non-signal transmission area (Q2) and avoids the signal transmission area (Q1).

[0033] A laminated glass assembly (100) is mounted on a vehicle. In one embodiment, the laminated glass assembly (100) is used as a front windshield of the vehicle. In another embodiment, it is used as a rear windshield of the vehicle. In this application, the use of the laminated glass assembly (100) as a front windshield of the vehicle is described as an example.

[0034] The laminated glass (110)) has a signal transmission area (Q1) and a non-signal transmission area (Q2), and a detection signal transmitted and / or received from the detector (200) is transmitted by passing through the signal transmission area (Q1). The signal transmission area (Q1) has a high transmittance for the detection signal, preferably the signal transmission area (Q1) has at least 85% transmittance for a detection signal incident at an angle of incidence of 55° to 70°, more preferably at least 90% transmittance, and even at least 95% transmittance, ensuring that the detector (200) in the vehicle operates normally and has a relatively high detection precision. The angle of incidence is a narrow angle between the incident detection signal and the normal of the signal transmission area (Q1).

[0035] Specifically, the wavelength range of the detection signal is 380 nm to 1650 nm or 3 mm to 30 mm. The detector (200) is, for example, a visible light camera (380 nm to 780 nm), a near-infrared camera (780 nm to 1650 nm), a laser radar (905 nm, 1550 nm), a millimeter wave radar (3 mm to 30 mm), etc., and is used for imaging, distance measurement and position determination, etc. It must be explained that the number of signal transmission areas (Q1) can be one or more and can be set according to actual demand.

[0036] Specifically, the detection signal may be circularly polarized, P-polarized, or a mixture of P-polarized and S-polarized light, with the proportion of P-polarized light in the mixture being 50% or more. In the case of laser radar, due to high requirements for vehicle safety, the signal transmission area (Q1) must have a higher transmittance for the detection signal of the laser radar. The angle of incidence of the detection signal is approximately similar to the Brewster angle of P-polarized light incident on laminated glass. Preferably, the detection signal of the laser radar is P-polarized or a mixture of P-polarized light having a proportion of 80% or more.

[0037] A radio wave transmission layer (120) is mounted on a laminated glass (110), and the orthographic projection of the radio wave transmission layer (120) on the laminated glass (110) covers a signal transmission area (Q1), and the radio wave transmission layer (120) can increase the transmittance of the signal transmission area (Q1) for a detection signal incident at an angle of incidence of 55° to 70°. The transmittance is measured and calculated according to the international standard ISO 9050 when the detection signal is incident at an angle of incidence of 55° to 70°. Preferably, the transmittance of the signal transmission area (Q1) having the radio wave transmission layer (120) for a detection signal incident at an angle of incidence of 55° to 70° is at least 3% higher than the transmittance of the signal transmission area (Q1) not having the radio wave transmission layer (120) for a detection signal incident at an angle of incidence of 55° to 70°, more preferably at least 5% higher, and even at least 8% higher.

[0038] The orthographic projection of the radio wave-transmitting layer (120) in the laminated glass (110) also covers a non-signal transmission area (Q2). The orthographic projection of the radio wave-transmitting layer (120) in the laminated glass (110) occupies more than 70% of the area of ​​the laminated glass (110), for example, 70%, 80%, 90%, 95%, 100%, etc. Therefore, after the radio wave-transmitting layer (120) is deposited on the laminated glass (110), there is no need to remove some of the radio wave-transmitting layer (120) corresponding to the non-signal transmission area (Q2), and in addition to increasing the transmittance of the signal transmission area (Q1) for the detection signal, the difficulty of processing is greatly reduced and production efficiency is improved.

[0039] The insulating layer (130) is mounted on the laminated glass (110), and the orthographic projection of the insulating layer (130) on the laminated glass (110) covers the non-signal transmission area (Q2) and does not cover the signal transmission area (Q1). That is, in order to prevent the transmittance of the signal transmission area (Q1) for the detection signal from decreasing due to the insulating layer (130), it is sufficient to remove only the portion of the insulating layer (130) corresponding to the signal transmission area (Q1) after the insulating layer (130) is deposited on the laminated glass (110). It must be explained that after performing a coating removal operation on the insulating layer (130) deposited on the laminated glass (110), the orthographic projection of the insulating layer (130) on the laminated glass (110) covers the non-signal transmission area (Q2) and avoids the signal transmission area (Q1). The orthographic projection of the insulation layer (130) in the laminated glass (110) occupies more than 70% of the area of ​​the laminated glass (110). The insulation layer (130) reflects or absorbs near-infrared rays so that the non-signal transmission area (Q2) of the laminated glass (110) has an insulating effect.

[0040] The overlapping area of ​​the orthographic projection of the radio wave-transmitting layer (120) in the laminated glass (110) and the orthographic projection of the insulating layer (130) in the laminated glass (110) occupies at least 80% of the orthographic projection of the insulating layer (130) in the laminated glass (110). Specifically, the total solar energy transmittance of the overlapping area of ​​the radio wave-transmitting layer (120) and the insulating layer (130) in the laminated glass (110) is less than or equal to 53%. The signal transmission area (Q1) has a transmittance of at least 85% for a detection signal incident at an angle of incidence of 55° to 70°, with a wavelength range of 380mm to 1650mm or 3mm to 30mm. This ensures that the laminated glass (110) still has an effective insulating effect without removing some of the radio wave-transmitting layer (120) corresponding to the non-signal transmission area (Q2).

[0041] The laminated glass assembly (100) provided in the present application comprises laminated glass (110), a radio wave-transmitting layer (120), and an insulating layer (130). The laminated glass (110) has a signal transmission area (Q1) and a non-signal transmission area (Q2). The radio wave-transmitting layer (120) is mounted on the laminated glass (110), and the orthographic projection of the radio wave-transmitting layer (120) on the laminated glass (110) covers the signal transmission area (Q1) and the non-signal transmission area (Q2). The insulating layer (130) is mounted on the laminated glass (110), and the orthographic projection of the insulating layer (130) on the laminated glass (110) covers the non-signal transmission area (Q2) and avoids the signal transmission area (Q1). In the laminated glass assembly provided in the present application, by removing the portion corresponding to the signal transmission area (Q1) in the insulation layer (130) and by the radio wave transmission layer (120) covering the signal transmission area (Q1) and the non-signal transmission area (Q2), the laminated glass assembly (100) not only has an insulation function but also improves the transmittance of the signal transmission area (Q1) for the detection signal, so that the laminated glass assembly (100) of the present application combines an insulation function and a local infrared high transmittance function.

[0042] In one embodiment, the laminated glass (110) comprises a first transparent substrate (1110), a second transparent substrate (1120), and an adhesive film (1130). The first transparent substrate (1110) has a first surface (1111) and a second surface (1112) installed facing each other. The second transparent substrate (1130) has a third surface (1131) and a fourth surface (1122) installed facing each other, and the third surface (1131) is installed closer to the second surface (1112) than to the fourth surface (1122). The adhesive film (1130) is used to bond the first transparent substrate (1110) and the second transparent substrate (1120).

[0043] In this embodiment, the intermediate adhesive film (1130) may be polyvinyl butyral (PVB), an ion adhesive film (e.g., SentryGlass®Plus (SGP)), ethylene-vinyl acetate (EVA), polyurethane (PU), etc., and the intermediate adhesive film (1130) only needs to adhere the first transparent substrate (1110) and the second transparent substrate (1120) together.

[0044] Below, one application scenario of laminated glass (110) is introduced. When laminated glass (110) is applied to a vehicle, the laminated glass (110) is mounted on the vehicle at a certain angle of inclination and used as a windshield. A first transparent substrate (1110) is used as a substrate for the laminated glass (110) exposed to the outside of the vehicle. A second transparent substrate (1120) is used as a substrate for the laminated glass (110) located inside the vehicle.

[0045] In one embodiment, according to ISO 9050, the first transparent substrate (1110) has a vertical visible light transmittance (TL) of 88% or more. In another embodiment, according to ISO 9050, the first transparent substrate (1110) has a vertical visible light transmittance (TL) of 90% or more. In yet another embodiment, according to ISO 9050, the first transparent substrate (1110) has a vertical visible light transmittance (TL) of 92% or more. This ensures the visible light transmittance of the laminated glass (110) and makes the field of view (FOV) of the laminated glass (110) clearer.

[0046] For example, the first transparent substrate (1110) may be soda-lime-silica glass, high-alumina glass, borosilicate glass, etc., and the second transparent substrate (1120) may be high-alumina glass or borosilicate glass. Thus, the strength of the laminated glass (110) is secured, and the laminated glass (110) can withstand impact of a certain strength. In addition, the thickness (d1) range of the first transparent substrate (1110) is 1.6 mm ≤ d1 ≤ 4 mm, the thickness (d2) range of the second transparent substrate (1120) is 0.3 mm ≤ d2 ≤ 2.3 mm, and the total thickness (d) of the laminated glass (110) after lamination satisfies d ≥ 4.2 mm. Therefore, laminated glass (110) can be ensured to be applied to different lightweight requirements.

[0047] In another embodiment, the laminated glass (110) has several transparent substrates and corresponding adhesive films (1130) that tightly bond the several transparent substrates. In the present application, for example, the laminated glass (110) has two transparent substrates.

[0048] It must be explained that, in this application, the thickness of the electromagnetic wave-transmitting layer (120) and the insulating layer (130) are both nanometer-sized, so the human eye cannot distinguish their thickness, and furthermore, the first transparent substrate (1110), the second transparent substrate (1120), the electromagnetic wave-transmitting layer (120), the insulating layer (130), and the adhesive film (1130) are closely connected without any gaps. To explain the structure of the laminated glass assembly (100) more clearly, the drawings of the laminated glass assembly (100) in this application show a layered structure by increasing the thickness of each component and separating each component. Below, the specific structure of the laminated glass assembly (100) is described.

[0049] Referring together to FIGS. 1, FIGS. 2, FIGS. 3, and FIGS. 4, FIG. 2 is a cross-sectional layered structure diagram along line AA of FIG. 1 according to one embodiment of the present application, FIG. 3 is a cross-sectional layered structure diagram along line AA of FIG. 1 according to another embodiment of the present application, and FIG. 4 is a cross-sectional layered structure diagram along line AA of FIG. 1 according to yet another embodiment of the present application. In one embodiment, the second transparent substrate (1120), the adhesive film (1130), and the insulating layer (130) all have through holes (140) communicating with each other, and at least a portion of each through hole (140) is in the signal transmission area (Q1). The radio wave transmission layer (120) is installed on the second surface (1112). The insulating layer (130) is installed on the surface of the radio wave-transmitting layer (120) near the second transparent substrate (1120) (as shown in FIG. 2), or the insulating layer (130) is installed on the third surface (1121) (as shown in FIG. 3), or the insulating layer (130) is installed within the adhesive film (1130) (as shown in FIG. 4).

[0050] In this embodiment, at least a portion of the through hole (140) is in the signal transmission area (Q1), that is, the through hole (140) can cover not only the signal transmission area (Q1) but also the non-signal transmission area (Q2). The detection signal of the detector (200) is transmitted through the through hole (140), the radio wave transmission layer (120), and the first transparent substrate (1110), but does not pass through the second transparent substrate (1120), the adhesive film (1130), and the insulating layer (130), thus avoiding the second transparent substrate (1120), the adhesive film (1130), and the insulating layer (130) blocking the detection signal, and the selection of the second transparent substrate (1120), the adhesive film (1130), and the insulating layer (130) is more free. For example, the second transparent substrate (1120) can be selected as colored glass, the adhesive film (1130) can be selected as an adhesive film having thermal insulation performance, and the insulation layer (130) can be selected as an insulation layer having higher performance, thereby making the product combination of laminated glass more diverse.

[0051] In this embodiment, the radio wave transmission layer (120) is installed on the second surface (1112), and by depositing the radio wave transmission layer (120) having a high signal transmission function on the second surface (1112) through a method such as physical vapor deposition (PVD) or chemical vapor deposition (CVD), the transmittance of the signal transmission area (Q1) for the detection signal can be increased.

[0052] In this embodiment, the insulating layer (130) is installed on the surface of the electromagnetic transmission layer (120) near the second transparent substrate (1120) (as shown in FIG. 2), or the insulating layer (130) is installed on the third surface (1121) (as shown in FIG. 3), or the insulating layer (130) is installed within the adhesive film (1130) (as shown in FIG. 4). The insulating layer (130) may be directly deposited on the surface of the electromagnetic transmission layer (120) near the second transparent substrate (1120) or on the third surface (1121) via a method such as PVD, CVD, or sol-gel spraying. Alternatively, the insulating layer (130) may be deposited on a polymer film such as polyethylene terephthalate (PET) and then laminated with the adhesive film (1130) to form a part of the adhesive film (1130).

[0053] An implementation method in which the orthographic projection of the insulating layer (130) in the laminated glass (110) avoids the signal transmission area (Q1) is as follows. In one embodiment, first, the insulating layer (130) may be deposited on the surface of the radio wave transmission layer (120) or the third surface (1121) near the second transparent substrate (1120), or the insulating layer (130) may be laminated with an adhesive film (1130) after being deposited on a polymer film to form a part of the adhesive film (1130). Then, a portion of the insulating layer (130) corresponding to the signal transmission area (Q1) in the insulating layer (130) is removed. In another embodiment, first, a mask layer is covered at a location corresponding to a signal transmission area (Q1) on the surface of the radio wave transmission layer (120) or the third surface (1121) near the second transparent substrate (1120), then an insulating layer (130) is deposited on the surface of the radio wave transmission layer (120) or the third surface (1121) near the second transparent substrate (1120), and later the mask layer is removed. Alternatively, first, a mask layer is covered at a location corresponding to a signal transmission area (Q1) in the polymer film, then an insulating layer (130) is deposited on the polymer film, the mask layer is removed, and later the insulating layer (130) and the adhesive film (1130) are laminated. Thus, the insulating effect of the laminated glass (110) can be maintained without affecting the transmittance of the signal transmission area (Q1) of the laminated glass (110) for the detection signal.

[0054] In this embodiment, the radio wave transmission layer (120) is used to improve the transmittance of the signal transmission area (Q1) for a detection signal incident at an angle of incidence of 55° to 70°. The radio wave transmission layer (120) includes a stacked structure of at least one high-refractive-index layer / low-refractive-index layer, the refractive index of the high-refractive-index layer is 1.9-2.6, and the refractive index of the low-refractive-index layer is 1.3-1.8. The transmittance is improved by designing a stacked structure of a high-refractive-index layer / low-refractive-index layer. The high-refractive-index layer includes a plurality of sublayers, and / or the low-refractive-index layer also includes a plurality of sublayers, and at least one of the material, thickness, and refractive index of each sublayer is different. The insulating layer (130) is used to reflect and / or absorb infrared rays, and to ensure that the laminated glass has a relatively good insulating effect. The insulating layer (130) comprises at least one of a metallic silver layer, a silver alloy layer, or a transparent conductive oxide (TCO) layer, wherein the metallic silver layer, the silver alloy layer, or the transparent conductive oxide layer has excellent infrared reflection performance and reduces the infrared transmittance of the laminated glass. The material of the silver alloy layer is preferably a silver-copper alloy, a silver-indium alloy, a silver-gold alloy, etc. The silver content of the silver alloy layer is preferably 95% or more, and more preferably 98% or more. The transparent conductive oxide layer comprises at least one transparent conductive oxide (TCO) layer, preferably ITO (Indium-doped tin oxide), FTO (fluorine-doped tin oxide), ATO (antimony-doped tin oxide), AZO (aluminum-doped zinc oxide), IZO (indium-doped zinc oxide), GZO (gallium-doped zinc oxide), etc. The insulating layer (130) also comprises another medium layer.

[0055] In related technologies, the implementation method for additionally installing a signal transmission area capable of increasing signal transmittance in insulating glass is generally as follows. After depositing a radio wave-transmitting layer on the entire surface of the glass via magnetron sputtering, the portion corresponding to the non-signal transmission area in the deposited radio wave-transmitting layer is removed. Alternatively, a mask layer is first applied to the non-signal transmission area of ​​the glass, followed by the deposition of the radio wave-transmitting layer on the glass, and then the mask layer is removed. Since the orthographic projection area of ​​the non-signal transmission area in the glass occupies more than 80% of the total glass area, adding a coating removal process for the signal transmission area, which has a relatively small area ratio in existing technologies, is not ideal in terms of production efficiency and process complexity. Consequently, quality costs in the mass production process remain high.

[0056] Compared to related technology, for example, specifically (as shown in FIG. 2), the vertical visible light transmittance TL of the first transparent substrate (1110) in ISO 9050 is 89.9%. A radio wave transmitting layer (120) is formed by sequentially depositing ZnSnOx with a thickness of 92 nm, TiOx with a thickness of 7 nm, SiO2 with a thickness of 117 nm, and TiOx with a thickness of 25 nm on the second surface (1112). Next, an insulating layer (130) is formed by sequentially depositing AZO with a thickness of 11 nm, Ag with a thickness of 12.8 nm, TiOx with a thickness of 9 nm, ZnSnOx with a thickness of 60 nm, AZO with a thickness of 20 nm, Ag with a thickness of 9.2 nm, TiOx with a thickness of 9 mm, AZO with a thickness of 8 nm, ZnSnOx with a thickness of 10 nm, and Si3N4 with a thickness of 10 nm on the surface of the electromagnetic wave-transmitting layer (120) near the second transparent substrate (1120). The insulating layer (130) in the portion corresponding to the signal transmission area (Q1) in the insulating layer (130) is removed. An experimental test is performed on a laminated glass assembly (100) mounted on a vehicle (1) at a mounting angle α of 60°. In the laminated glass assembly (100), the vertical visible light transmittance TL of the overlapping area of ​​the radio wave transmission layer (120) in the laminated glass (110) and the thermal insulation layer (130) in the laminated glass (110) is 75.6%. In the laminated glass assembly (100), the reflectance RL for visible light on the fourth surface (1122) side of the overlapping area of ​​the radio wave transmission layer (120) in the laminated glass (110) and the thermal insulation layer (130) in the laminated glass (110) is 14.1%. In the laminated glass assembly (100), the total solar energy transmittance TTS of the overlapping area of ​​the radio wave transmission layer (120) in the laminated glass (110) and the insulation layer (130) in the laminated glass (110) is 51.3%.According to the International Commission on Illumination (CIE) 1976 standard, the color value expression formula for the overlapping area of ​​the radio wave transmission layer (120) in the laminated glass (110) and the thermal insulation layer (130) in the laminated glass (110) is L*=43.8, a*=-1.8, b*=-9.8, and the appearance is blue. The transmittance Ts1 of the signal transmission area (Q1) for a detection signal with a wavelength of 905 nm incident at an angle of incidence of 60° is 87.04%, and the transmittance Ts2 of the signal transmission area (Q1) where the radio wave transmission layer (120) is not deposited for a detection signal with a wavelength of 905 nm incident at an angle of incidence of 60° is 81.5%, and the transmittance Ts1 is 5.54% higher than the transmittance Ts2. As can be concluded from the experimental test, in this embodiment, insulation can be effectively performed due to the installation of the insulation layer (130), and the signal transmittance of the signal transmission area (Q1) can be effectively improved due to the installation of the radio wave transmission layer (120). Furthermore, the overlapping installation of the insulation layer (130) and the radio wave transmission layer (120) can produce a color appearance that makes the human eye feel comfortable, for example, light blue.

[0057] In this embodiment (as shown in FIG. 2), only the portion corresponding to the signal transmission area (Q1) of the insulation layer (130) needs to be removed, and there is no need to remove the portion corresponding to the non-signal transmission area (Q2) of the radio wave transmission layer (120), thus making the manufacturing process simpler. Therefore, the laminated glass assembly (100) of the present application combines an insulation function and a local infrared high transmittance function, and has high manufacturing efficiency. In addition, in this embodiment, a portion of the radio wave transmission layer (120) can be used as a base substrate for the insulation layer (130). During the processing and molding process of the laminated glass assembly (100), the radio wave transmission layer (120) can effectively prevent alkali metal ions of the first transparent substrate (1110) from moving to the insulation layer (130). Therefore, it is possible to ensure that the thermal insulation function of the thermal insulation layer (130) is not damaged during the manufacturing process of the laminated glass assembly (100) without additionally installing a base film layer to protect the thermal insulation layer, and the radio wave transmission layer (120) also serves as a color control layer. The process of depositing the radio wave transmission layer (120) and the thermal insulation layer (130) sequentially on the second surface (1112) is effective and simple, allowing the laminated glass assembly (100) to possess both thermal insulation and local infrared high transmittance functions, and manufacturing efficiency is high.

[0060] In this embodiment, the radio wave transmission layer (120) is installed on the fourth surface (1122), and by depositing the radio wave transmission layer (120) having a high signal transmission function on the fourth surface (1122) through a method such as physical vapor deposition (PVD) or chemical vapor deposition (CVD), the transmittance of the signal transmission area (Q1) for the detection signal can be increased.

The insulating layer (130) may be directly deposited on the second surface (1112) or the third surface (1121) by means of PVD, CVD, or sol-gel spraying. Alternatively, the insulating layer (130) may be deposited on a polymer film such as polyethylene terephthalate (PET) and then laminated with the adhesive film (1130) to form a part of the adhesive film (1130).

[0062] An implementation method in which the orthographic projection of the insulating layer (130) in the laminated glass (110) avoids the signal transmission area (Q1) is as follows.

Alternatively, first, a mask layer is covered at a location corresponding to a signal transmission area (Q1) in the polymer film, then an insulating layer (130) is deposited on the polymer film, the mask layer is removed, and later the insulating layer (130) and the adhesive film (1130) are laminated. Thus, the insulating effect of the laminated glass (110) can be maintained without affecting the transmittance of the signal transmission area (Q1) of the laminated glass (110) for the detection signal.

[0066] In this embodiment, the insulating layer (130) is installed on the second surface (1112) (as shown in FIG. 8), or the insulating layer (130) is installed on the surface of the electromagnetic transmission layer (120) near the first transparent substrate (1110) (as shown in FIG. 9), or the insulating layer (130) is installed within the adhesive film (1130) (as shown in FIG. 10). The insulating layer (130) may be directly deposited on the surface of the second surface (1112) or the electromagnetic transmission layer (120) near the first transparent substrate (1110) via a method such as PVD, CVD, or sol-gel spraying. Alternatively, the insulating layer (130) may be deposited on a polymer film such as PET and then laminated with the adhesive film (1130) to form a part of the adhesive film (1130).

[0067] An implementation method in which the orthographic projection of the insulating layer (130) in the laminated glass (110) avoids the signal transmission area (Q1) is as follows. In one embodiment, first, the insulating layer (130) may be deposited on the surface of the radio wave-transmitting layer (120) near the second surface (1112) or the first transparent substrate (1110), or the insulating layer (130) may be laminated with an adhesive film (1130) after being deposited on a polymer film and become part of the adhesive film (1130).

[0069] In this embodiment, depending on actual demand, a through hole (140) is opened in an inner area or at the edge of the laminated glass assembly (100). A signal transmission area (Q1) is installed corresponding to the through hole (140), and the orthographic area S of the signal transmission area (Q1) on the second surface (1112) satisfies S≥50mm*80mm.
