[0003] With the development of intelligent driving vehicles, the demand for installing detectors inside vehicles is gradually increasing, and insulating glass is widely used for vehicle windows. When a detection signal from a detector passes through the insulating glass, it is absorbed and / or reflected by the insulating glass. Therefore, the transmittance of the insulating glass to the detection signal transmitted by the detector is significantly reduced, which reduces the detection accuracy of the detector and prevents the detector from operating normally.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments that can be obtained by those skilled in the art without creative efforts are all within the protection scope of the present application.

[0026] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the present application. Appearance of such a term anywhere in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. Those skilled in the art can explicitly or implicitly understand that the embodiments described herein can be combined with other embodiments.

[0027] Referring to FIG. 1, FIG. 1 is a schematic diagram showing a laminated glass assembly according to one embodiment of the present application. The present application provides a laminated glass assembly 100. The laminated glass assembly 100 includes a laminated glass 110, a radio wave transparent layer 120, and a thermal insulation layer 130. The laminated glass 110 has a signal transmission region Q1 and a non-signal transmission region Q2. The radio wave transparent layer 120 is placed on the laminated glass 110, and an orthogonal projection of the radio wave transparent layer 120 on the laminated glass 110 covers the signal transmission region Q1 and the non-signal transmission region Q2. The thermal insulation layer 130 is placed on the laminated glass 110, and an orthogonal projection of the thermal insulation layer 130 on the laminated glass 110 covers the non-signal transmission region Q2 and avoids the signal transmission region Q1.

[0028] The laminated glass assembly 100 is used to be installed in a vehicle. In one embodiment, the laminated glass assembly 100 is installed as a windshield of the vehicle. In another embodiment, the laminated glass assembly 100 is installed as a rear window glass of the vehicle. In this application, the laminated glass assembly 100 is described as being installed as a windshield of the vehicle.

[0029] The laminated glass 110 has a signal transmission region Q1 and a non-signal transmission region Q2. The detection signal transmitted and / or received by the detector 200 is transmitted through the signal transmission region Q1. The signal transmission region Q1 has a relatively high transmittance for the detection signal. The signal transmission region Q1 preferably has a transmittance of 85% or more for the detection signal incident at an incident angle of 55° to 70°, more preferably 90% or more, and even more preferably 95% or more. This ensures that the detector 200 inside the vehicle operates normally and has high detection accuracy. Here, the incident angle is the angle between the incident detection signal and the normal to the signal transmission region Q1.

[0030] Specifically, the wavelength of the detection signal is in the range of 380 nm to 1650 nm or 3 mm to 30 mm. Examples of the detector 200 include a visible light camera (380 nm to 780 nm), a near-infrared camera (780 nm to 1650 nm), a laser radar (light detection and ranging, LiDAR) (905 nm, 1550 nm), and a millimeter-wave radar (3 mm to 30 mm), and are used for imaging, ranging, positioning, etc. The number of signal transmission regions Q1 may be one or more, and can be set according to actual needs.

[0031] Specifically, the detection signal may be circularly polarized light, P-polarized light, or a mixed light of P-polarized light and S-polarized light, with the proportion of P-polarized light in the mixed light being 50% or more. In the case of laser radar, due to high requirements for vehicle safety, the signal transmission region Q1 needs to have high transmittance for the detection signal from the laser radar. It is preferable that the Brewster angle of the P-polarized light incident on the laminated glass is approximately equal to the angle of incidence of the detection signal, and the detection signal from the laser radar is P-polarized light or a mixed light with a proportion of P-polarized light of 80% or more.

[0032] The radio wave transmission layer 120 is placed on the laminated glass 110, and the orthogonal projection of the radio wave transmission layer 120 on the laminated glass 110 covers the signal transmission region Q1. The radio wave transmission layer 120 can increase the transmittance of the signal transmission region Q1 for detection signals incident at an incident angle of 55° to 70°. The transmittance is measured and calculated in accordance with International Organization for Standardization (ISO) 9050 when the detection signal is incident at an incident angle of 55° to 70°. Preferably, the transmittance of the signal transmission region Q1 with the radio wave transmission layer 120 for detection signals incident at an incident angle of 55° to 70° is at least 3% greater, more preferably at least 5% greater, and even at least 8% greater, than the transmittance of the signal transmission region Q1 without the radio wave transmission layer 120 for detection signals incident at an incident angle of 55° to 70°.

[0033] The orthogonal projection of the radio wave transmission layer 120 on the laminated glass 110 further covers the non-signal transmission region Q2. The orthogonal projection of the radio wave transmission layer 120 on the laminated glass 110 occupies 70% or more of the area of ​​the laminated glass 110, for example, 70%, 80%, 90%, 95%, or 100%. Therefore, after the radio wave transmission layer 120 is deposited on the laminated glass 110, it is not necessary to remove the portion of the radio wave transmission layer 120 that corresponds to the non-signal transmission region Q2. This not only ensures improved transmittance for the detection signal in the signal transmission region Q1, but also significantly reduces the difficulty of the process and improves production efficiency.

[0034] The insulating layer 130 is placed on the laminated glass 110, and the orthogonal projection of the insulating layer 130 on the laminated glass 110 covers the non-signal transmission region Q2 but not the signal transmission region Q1. That is, to ensure that the insulating layer 130 does not reduce the transmittance of the detection signal in the signal transmission region Q1, only a portion of the insulating layer 130 corresponding to the signal transmission region Q1 needs to be removed after the insulating layer 130 is deposited on the laminated glass 110. After the insulating layer 130 is deposited on the laminated glass 110 and the film removal operation is performed, the orthogonal projection of the insulating layer 130 on the laminated glass 110 covers the non-signal transmission region Q2 but avoids the signal transmission region Q1. The orthogonal projection of the insulating layer 130 on the laminated glass 110 occupies more than 70% of the area of ​​the laminated glass 110. The insulating layer 130 reflects or absorbs near-infrared rays, providing a thermal insulation effect to the non-signal transmission region Q2 of the laminated glass 110.

[0035] The overlapping area between the orthogonal projection of the radio wave transmission layer 120 on the laminated glass 110 and the orthogonal projection of the heat insulating layer 130 on the laminated glass 110 accounts for 80% or more of the area of ​​the orthogonal projection of the heat insulating layer 130 on the laminated glass 110. Specifically, the laminated glass 110 has the radio wave transmission layer 120 Orthogonal projection on the laminated glass 110 and insulation layer 130 Orthogonal projection on the laminated glass 110 The signal transmission area Q1 has a total solar energy transmittance of 53% or less in the overlap area with the wavelength of 380 nm ~1650 nmOr, the transmittance is 85% or more for detection signals incident at an incident angle of 55° to 70° within a range of 3 mm to 30 mm, thereby ensuring that the laminated glass 110 still has an effective heat insulating effect without removing a portion of the radio wave transparent layer 120 corresponding to the non-signal transmission area Q2.

[0036] The laminated glass assembly 100 according to the present application comprises a laminated glass 110, a radio wave transparent layer 120, and a thermal insulation layer 130. The laminated glass 110 has a signal transmission region Q1 and a non-signal transmission region Q2. The radio wave transparent layer 120 is placed on the laminated glass 110, and an orthogonal projection of the radio wave transparent layer 120 on the laminated glass 110 covers the signal transmission region Q1 and the non-signal transmission region Q2. The thermal insulation layer 130 is placed on the laminated glass 110, and an orthogonal projection of the thermal insulation layer 130 on the laminated glass 110 covers the non-signal transmission region Q2 and avoids the signal transmission region Q1. In the laminated glass assembly of the present application, a portion of the insulating layer 130 corresponding to the signal transmission region Q1 is removed, and the radio wave transparent layer 120 covers the signal transmission region Q1 and the non-signal transmission region Q2, thereby imparting insulating properties to the laminated glass assembly 100 and improving the transmittance of the detection signal in the signal transmission region Q1. As a result, the laminated glass assembly 100 of the present application achieves both insulating properties and high local infrared transmittance.

[0037] In one embodiment, the laminated glass 110 includes a first transparent substrate 1110, a second transparent substrate 1120, and an adhesive film. The first transparent substrate 1110 has a first surface 1111 and a second surface 1112 facing the first surface 1111. The second transparent substrate 1120 has a third surface 1121 and a fourth surface 1122 facing the third surface 1121, with the third surface 1121 being closer to the second surface 1112 than the fourth surface 1122. The adhesive film 1130 is used to bond the first transparent substrate 1110 and the second transparent substrate 1120 together.

[0038] In this embodiment, the intermediate adhesive film 1130 is a polyvinyl butyral (PVB) ionic adhesive film (e.g., Sentry Glass (R) The intermediate adhesive film 1130 may be made of a material such as polyethylene terephthalate (PEP), ethylene vinyl acetate (EVA), or polyurethane (PU), and it is sufficient for the intermediate adhesive film 1130 to firmly bond the first transparent substrate 1110 and the second transparent substrate 1120 together.

[0039] The following describes one application scenario of the laminated glass 110. When the laminated glass 110 is used in a vehicle, the laminated glass 110 is attached to the vehicle as a windshield at a specific inclination angle. The first transparent substrate 1110 of the laminated glass 110 is the substrate of the laminated glass 110 exposed to the outside of the vehicle, and the second transparent substrate 1120 is the substrate of the laminated glass 110 inside the vehicle.

[0040] In one embodiment, the first transparent substrate 1110 has a vertical visible light transmittance (TL) of 88% or greater according to ISO9050. In another embodiment, the first transparent substrate 1110 has a vertical visible light transmittance (TL) of 90% or greater according to ISO9050. In yet another embodiment, the first transparent substrate 1110 has a vertical visible light transmittance (TL) of 92% or greater according to ISO9050. The visible light transmittance of the laminated glass 110 is ensured, resulting in a clearer field of view (FOV) through the laminated glass 110.

[0041] For example, the first transparent substrate 1110 may be soda-lime-silica glass, high-alumina glass, or borosilicate glass, and the second transparent substrate 1120 may be high-alumina glass or borosilicate glass. This ensures the strength of the laminated glass 110 and allows the laminated glass 110 to withstand a certain level of impact. At the same time, the thickness d1 of the first transparent substrate 1110 is in the range of 1.6 mm≦d1≦4 mm, the thickness d2 of the second transparent substrate 1120 is in the range of 0.3 mm≦d2≦2.3 mm, and the total thickness d of the laminated glass 110 after lamination is d≧4.2 mm. This ensures that the laminated glass 110 can be adapted to different lightweight requirements.

[0042] In another embodiment, the laminated glass 110 has multiple transparent substrates, and accordingly has multiple adhesive films 1130 that enable the multiple transparent substrates to be firmly bonded together. In this application, an example will be described in which the laminated glass 110 has two transparent substrates.

[0043] In this application, the thicknesses of the radio wave transmission layer 120 and the heat insulating layer 130 are measured at the nm level, and are therefore indistinguishable from the human eye. The first transparent substrate 1110, the second transparent substrate 1120, the radio wave transmission layer 120, the heat insulating layer 130, and the adhesive film 1130 are closely connected, with no gaps between them. To more clearly illustrate the structure of the laminated glass assembly 100, the drawings of the laminated glass assembly 100 in this application show the thickness of each component as increased and the components as separated layers. The specific structure of the laminated glass assembly 100 will now be described.

[0044] 1, 2, 3, and 4, FIG. 2 is a cross-sectional view of a layer structure taken along line AA in FIG. 1 according to one embodiment of the present application. FIG. 3 is a cross-sectional view of a layer structure taken along line AA in FIG. 1 according to another embodiment of the present application. FIG. 4 is a cross-sectional view of a layer structure taken along line AA in FIG. 1 according to another embodiment of the present application. In one embodiment, the second transparent substrate 1120, the adhesive film 1130, and the heat insulating layer 130 all have through-holes 140 communicating with each other, and at least a portion of each through-hole 140 is located in the signal transmission region Q1. The radio wave transparent layer 120 is disposed on the second surface 1112. The heat insulating layer 130 is disposed on a surface of the radio wave transparent layer 120 close to the second transparent substrate 1120 (as shown in FIG. 2), or the heat insulating layer 130 is disposed on the third surface 1121 (as shown in FIG. 3), or the heat insulating layer 130 is disposed within the adhesive film 1130 (as shown in FIG. 4).

[0045] In this embodiment, at least a portion of each through-hole 140 is located in the signal transmission region Q1. That is, the through-holes 140 are located not only in the signal transmission region Q1 but also in the non-signal transmission region Q2. The detection signal from the detector 200 is transmitted through the through-hole 140, the radio wave transmission layer 120, and the first transparent substrate 1110, without passing through the second transparent substrate 1120, the adhesive film 1130, and the thermal insulation layer 130. This avoids blocking of the detection signal by the second transparent substrate 1120, the adhesive film 1130, and the thermal insulation layer 130, and increases the flexibility of selection of the second transparent substrate 1120, the adhesive film 1130, and the thermal insulation layer 130. For example, the second transparent substrate 1120 can be colored glass. The adhesive film 1130 can be an adhesive film with thermal insulation properties. The thermal insulation layer 130 can be a thermal insulation layer with higher performance. This allows for a more diverse product mix of laminated glass.

[0046] In this embodiment, the radio wave transparent layer 120 is disposed on the second surface 1112. The radio wave transparent layer 120, which has a function of high signal transmittance, can be deposited on the second surface 1112 by methods such as physical vapor deposition (PVD) or chemical vapor deposition (CVD), thereby increasing the transmittance of the signal transmission region Q1 to the detection signal.

[0047] In this embodiment, the heat insulating layer 130 is provided on the surface of the radio wave transparent layer 120 close to the second transparent substrate 1120 (as shown in FIG. 2), or the heat insulating layer 130 is provided on the third surface 1121 (as shown in FIG. 3), or the heat insulating layer 130 is provided in the adhesive film 1130 (as shown in FIG. 4). The heat insulating layer 130 can be deposited directly on the surface of the radio wave transparent layer 120 close to the second transparent substrate 1120 or on the third surface 1121 by methods such as PVD, CVD, or sol-gel spraying. Alternatively, the heat insulating layer 130 can be deposited on a polymer film such as polyethylene terephthalate (PET), and then interlaid into the adhesive film 1130, thereby becoming a part of the adhesive film 1130.

[0048] The following is an embodiment in which the orthogonal projection of the thermal insulation layer 130 on the laminated glass 110 avoids the signal transmission region Q1. In one embodiment, the thermal insulation layer 130 can be first deposited on the surface of the radio wave transmission layer 120 closest to the second transparent substrate 1120 or on the third surface 1121. Alternatively, the thermal insulation layer 130 can be deposited on a polymer film and then inserted into the adhesive film 1130 to become part of the adhesive film 1130. Next, a portion of the thermal insulation layer 130 corresponding to the signal transmission region Q1 is removed. In another embodiment, a masking layer is first applied to the surface of the radio wave transmission layer 120 closest to the second transparent substrate 1120 or the third surface 1121, in a location corresponding to the signal transmission region Q1. Next, the thermal insulation layer 130 is deposited on the surface of the radio wave transmission layer 120 closest to the second transparent substrate 1120 or on the third surface 1121. Finally, the masking layer is removed. Alternatively, a masking layer is first applied to a portion of the polymer film corresponding to the signal transmission region Q1. Next, a heat insulating layer 130 is deposited on the polymer film, and the masking layer is removed. Finally, the heat insulating layer 130 is inserted into the adhesive film 1130. This allows the heat insulating effect of the laminated glass 110 to be maintained without affecting the transmittance of the detection signal in the signal transmission region Q1.

[0049] In this embodiment, the radio wave transmission layer 120 is used to increase the transmittance of the signal transmission region Q1 for detection signals incident at an incident angle of 55° to 70°. The radio wave transmission layer 120 has at least one laminate structure including a high-refractive index layer and a low-refractive index layer, where the high-refractive index layer has a refractive index of 1.9 to 2.6 and the low-refractive index layer has a refractive index of 1.3 to 1.8. The laminate structure including the high-refractive index layer and the low-refractive index layer is designed to increase the transmittance. The high-refractive index layer may have multiple sublayers, and / or the low-refractive index layer may have multiple sublayers, where the high-refractive index layer and the low-refractive index layer differ in at least one of the material, thickness, or refractive index of each sublayer. The thermal insulation layer 130 is used to reflect and / or absorb infrared rays to improve the thermal insulation effect of the laminated glass. The thermal insulation layer 130 includes at least one of a metallic silver layer, a silver alloy layer, or a transparent conductive oxide (TCO) layer. The metallic silver layer, silver alloy layer, or TCO layer has good infrared reflectivity, thereby reducing the infrared transmittance of the laminated glass. The silver alloy layer is preferably made of a silver-copper alloy, a silver-indium alloy, a silver-gold alloy, or the like. The silver content of the silver alloy layer is preferably 95% or more, more preferably 98% or more. The TCO layer includes at least one TCO layer, and is preferably made of indium-doped tin oxide (ITO), fluorine-doped tin oxide (FTO), antimony-doped tin oxide (ATO), aluminum-doped zinc oxide (AZO), indium-doped zinc oxide (IZO), gallium-doped zinc oxide (GZO), or the like. The thermal insulation layer 130 further includes other dielectric layers.

[0050] In related art, the following process is typically used to add a signal transmission area to insulating glass to increase signal transmittance: After depositing a radio wave transparent layer over the entire surface of the glass by magnetron sputtering, the portion of the deposited radio wave transparent layer corresponding to the non-signal transmission area is removed. Alternatively, a masking layer is first applied to the portion of the glass corresponding to the non-signal transmission area, followed by depositing a radio wave transparent layer on the glass, and finally removing the masking layer. However, because the orthogonal projection area of ​​the non-signal transmission area accounts for more than 80% of the area of ​​the glass, the related art method of adding a film removal process for the signal transmission area, which accounts for a relatively small area, is not ideal in terms of production efficiency and process complexity. As a result, the quality cost in batch production is high.

[0051] Compared with the related art, for example, specifically (as shown in FIG. 2 ), according to ISO9050, the first transparent substrate 1110 has a vertical visible light transmittance TL of 89.9%. 92 nm thick ZnSnOx, 7 nm thick TiOx, 117 nm thick SiO2, and 25 nm thick TiOx are sequentially deposited on the second surface 1112 to form the radio wave transmission layer 120. Next, 11 nm thick AZO, 12.8 nm thick Ag, 9 nm thick TiOx, 60 nm thick ZnSnOx, 20 nm thick AZO, 9.2 nm thick Ag, 9 nm thick TiOx, 8 nm thick AZO, 10 nm thick ZnSnOx, and 10 nm thick Si3N4 are sequentially deposited on the surface of the radio wave transmission layer 120 closest to the second transparent substrate 1120 to form the thermal insulation layer 130. Furthermore, a portion of the thermal insulation layer 130 corresponding to the signal transmission region Q1 is removed. Experimental tests are performed on a laminated glass assembly 100 mounted on a vehicle 1 at an angle α of 60°. Orthogonal projection on the laminated glass 110 and insulation layer 130 Orthogonal projection on the laminated glass 110 In the overlapping region with the radio wave transmitting layer 120, the vertical visible light transmittance TL of the laminated glass assembly 100 is 75.6%. Orthogonal projection on the laminated glass 110 and insulation layer 130 Orthogonal projection on the laminated glass 110 In the overlap region with the fourth surface 1122, the laminated glass assembly 100 has a reflectivity RL of 14.1% for visible light incident on the fourth surface 1122. Orthogonal projection on the laminated glass 110and insulation layer 130 Orthogonal projection on the laminated glass 110 In the overlap region with the radio wave transparent layer 120, the laminated glass assembly 100 has a total solar energy transmittance (TTS) of 51.3%. Orthogonal projection on the laminated glass 110 and insulation layer 130 Orthogonal projection on the laminated glass 110 In the overlapping region, the color value expression formula of the laminated glass assembly 100 is L*=43.8, a*=-1.8, b*=-9.8, and the laminated glass assembly 100 has a light blue appearance. The signal transmission region Q1 has a transmittance Ts1 of 87.04% for a detection signal with a wavelength of 905 nm incident at an incident angle of 60°, and the signal transmission region Q1 without the radio wave transparent layer 120 has a transmittance Ts2 of 81.5% for a detection signal with a wavelength of 905 nm incident at an incident angle of 60°, which is an improvement of 5.54%. As can be seen from experimental tests, in this embodiment, the heat insulating layer 130 can be set to effectively block heat, the radio wave transmission layer 120 can be set to effectively increase the transmittance of signals in the signal transmission region Q1, and the overlapping of the heat insulating layer 130 and the radio wave transmission layer 120 can also provide a color appearance that is pleasant to the eye, such as light blue.

[0052] In this embodiment (as shown in FIG. 2 ), it is not necessary to remove a portion of the radio wave transmission layer 120 corresponding to the non-signal transmission region Q2, and only a portion of the thermal insulation layer 130 corresponding to the signal transmission region Q1 is removed, thereby simplifying the manufacturing process. Therefore, the laminated glass assembly 100 of the present application achieves both thermal insulation and high local infrared transmittance, and is manufactured with high efficiency. At the same time, in this embodiment, a portion of the radio wave transmission layer 120 can serve as a base for the thermal insulation layer 130. During the processing and molding of the laminated glass assembly 100, the radio wave transmission layer 120 can effectively prevent alkali metal ions in the first transparent substrate 1110 from being liberated into the thermal insulation layer 130. Therefore, the thermal insulation function of the thermal insulation layer 130 can be maintained during the manufacturing process of the laminated glass 100, even without the need for an additional base film layer to protect the thermal insulation layer. Furthermore, the radio wave transmission layer 120 can also perform color adjustment. The process of sequentially depositing the radio wave transparent layer 120 and the heat insulating layer 130 on the second surface 1112 is efficient and simple, and therefore the laminated glass assembly 100 can be produced efficiently while simultaneously achieving both heat insulating properties and high local infrared transmittance.

In another embodiment, the heat insulating layer 130 and the adhesive film 1130 both have through-holes 140 communicating with each other, and at least a portion of each through-hole 140 is located in the signal transmission region Q1.

[0054] In this embodiment, at least a portion of each through-hole 140 is located in the signal transmission region Q1. That is, the through-holes 140 are located not only in the signal transmission region Q1 but also in the non-signal transmission region Q2. The detection signal from the detector 200 does not pass through the adhesive film 1130 and the heat insulating layer 130, but passes through the radio wave transmission layer 120, the second transparent substrate 1120, the through-holes 140, and the first transparent substrate 1110. This prevents the adhesive film 1130 and the heat insulating layer 130 from blocking the detection signal.

[0055] In this embodiment, the radio wave transparent layer 120 is disposed on the fourth surface 1122. The radio wave transparent layer 120, which has the function of high signal transmittance, can be deposited on the fourth surface 1122 by methods such as PVD or CVD, thereby increasing the transmittance of the signal transmission region Q1 to the detection signal.

[0056] In this embodiment, the thermal insulation layer 130 is provided on the second surface 1112 (as shown in FIG. 5), or the thermal insulation layer 130 is provided on the third surface 1121 (as shown in FIG. 6), or the thermal insulation layer 130 is provided within the adhesive film 1130 (as shown in FIG. 7). The thermal insulation layer 130 can be deposited directly on the second surface 1112 or the third surface 1121 by methods such as PVD, CVD, or sol-gel spraying. Alternatively, the thermal insulation layer 130 can be deposited on a polymer film such as PET and then inserted into the adhesive film 1130, thereby becoming part of the adhesive film 1130.

[0057] The following is an embodiment in which the orthogonal projection of the thermal insulation layer 130 on the laminated glass 110 avoids the signal transmission region Q1. In one embodiment, the thermal insulation layer 130 can be first deposited on the second surface 1112 or the third surface 1121, or the thermal insulation layer 130 is deposited on a polymer film and then inserted into the adhesive film 1130 to become part of the adhesive film 1130. Next, a portion of the thermal insulation layer 130 corresponding to the signal transmission region Q1 is removed. In another embodiment, a masking layer is first applied to the second surface 1112 or the third surface 1121 in a portion corresponding to the signal transmission region Q1. Next, the thermal insulation layer 130 is deposited on the second surface 1112 or the third surface 1121. Finally, the masking layer is removed. Alternatively, a masking layer is first applied to a portion of the polymer film corresponding to the signal transmission region Q1. Next, the thermal insulation layer 130 is deposited on the polymer film, and then the masking layer is removed. Finally, the heat insulating layer 130 is inserted into the adhesive film 1130. This makes it possible to maintain the heat insulating effect of the laminated glass 110 without affecting the signal transmittance of the signal transmission region Q1 of the laminated glass 110.

[0059] In this embodiment, at least a portion of each through-hole 140 is located in the signal transmission region Q1. That is, the through-holes 140 are located not only in the signal transmission region Q1 but also in the non-signal transmission region Q2. The detection signal from the detector 200 does not pass through the adhesive film 1130 and the heat insulating layer 130, but passes through the second transparent substrate 1120, the radio wave transmission layer 120, the through-holes 140, and the first transparent substrate 1110. This prevents the adhesive film 1130 and the heat insulating layer 130 from blocking the detection signal.

[0060] In this embodiment, the radio wave transmission layer 120 is disposed on the third surface 1121. The radio wave transmission layer 120, which has the function of high signal transmittance, can be deposited on the third surface 1121 by methods such as PVD or CVD, thereby increasing the transmittance of the signal transmission region Q1 to the detection signal.

[0061] In this embodiment, the thermal insulation layer 130 is provided on the second surface 1112 (as shown in FIG. 8 ), or on the surface of the radio wave transparent layer 120 close to the first transparent substrate 1110 (as shown in FIG. 9 ), or in the adhesive film 1130 (as shown in FIG. 10 ). The thermal insulation layer 130 can be deposited directly on the second surface 1112 or on the surface of the radio wave transparent layer 120 close to the first transparent substrate 1110 by methods such as PVD, CVD, or sol-gel spraying. Alternatively, the thermal insulation layer 130 is deposited on a polymer film such as PET and then inserted into the adhesive film 1130, thereby becoming a part of the adhesive film 1130.

[0062] The following is an embodiment in which the orthogonal projection of the thermal insulation layer 130 on the laminated glass 110 avoids the signal transmission region Q1. In one embodiment, the thermal insulation layer 130 can be first deposited on the second surface 1112 or on the surface of the radio wave transparent layer 120 close to the first transparent substrate 1110. Alternatively, the thermal insulation layer 130 can be deposited on a polymer film and then inserted into the adhesive film 1130 to become part of the adhesive film 1130. Next, a portion of the thermal insulation layer 130 corresponding to the signal transmission region Q1 is removed. In another embodiment, a masking layer is first applied to the second surface 1112 or the surface of the radio wave transparent layer 120 close to the first transparent substrate 1110, in a location corresponding to the signal transmission region Q1. Next, the thermal insulation layer 130 is deposited on the second surface 1112 or on the surface of the radio wave transparent layer 120 close to the first transparent substrate 1110. Finally, the masking layer is removed. Alternatively, a masking layer is first applied to a portion of the polymer film corresponding to the signal transmission region Q1. Next, a heat insulating layer 130 is deposited on the polymer film, and the masking layer is removed. Finally, the heat insulating layer 130 is inserted into the adhesive film 1130. This allows the heat insulating effect of the laminated glass 110 to be maintained without affecting the transmittance of the detection signal in the signal transmission region Q1.

The area S of the orthogonal projection of the second surface 1112 of the signal transmission region Q1 is S≧50 mm*80 mm.

[0064] In this embodiment, multiple through holes 140 can be provided in the interior region or the edge of the laminated glass assembly 100 according to actual needs. A signal transmission region Q1 is provided corresponding to the through holes 140, and the area S of the orthogonal projection of the signal transmission region Q1 on the second surface 1112 is S≧50mm*80mm. Typically, a detector 200 needs to be placed in the signal transmission region Q1 and used to transmit and receive detection signals.

It has a blocking rate of 5% or less for detection signals incident at an incident angle of 55° to 70°, thereby ensuring high transmittance for detection signals in the signal transmission region Q1.

[0066] In this embodiment, the material of the filler 150 may be the same as or different from the material of the adhesive film 1130. Preferably, the blocking rate of the filler 150 for detection signals incident at an incident angle of 55° to 70° is smaller than the blocking rate of the adhesive film 1130 for detection signals incident at an incident angle of 55° to 70°.
