BACKGROUND

With the development of intelligent driving vehicles, application requirements for mounting detectors in the vehicle gradually increase, and thermal insulation glass is increasingly used as vehicle window glass. When passing through the thermal insulation glass, detection signals from the detector are absorbed and/or reflected by the thermal insulation glass. Therefore, a transmittance of the thermal insulation glass for the detection signal transmitted from the detector is greatly reduced, so that detection accuracy of the detector is reduced and the detector is unable to work normally.

It is expressly and implicitly understood by those skilled in the art that an embodiment described herein may be combined with other embodiments.

Reference can be made to FIG. 1, which is a schematic view of a laminated glass assembly provided in an implementation of the present disclosure. A laminated glass assembly 100 is provided in the present disclosure. The laminated glass assembly 100 includes laminated glass 110, a 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 wave transparent layer 120 is carried on the laminated glass 110. An orthographic projection of the 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 carried on the laminated glass 110. An orthographic 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.

The laminated glass assembly 100 is mounted on a vehicle. In an implementation, the laminated glass assembly 100 is mounted as a front windshield of the vehicle. In another implementation, the laminated glass assembly 100 is mounted as a rear window of the vehicle. In the present disclosure, for example, the laminated glass assembly 100 is mounted as the front windshield of the vehicle.

The laminated glass 110 has the signal transmission region Q1 and the non-signal transmission region Q2. A detection signal emitted and/or received by a detector 200 is transmitted through the signal transmission region Q1. A transmittance of the signal transmission region Q1 for the detection signal is relatively high. Preferably, the signal transmission region Q1 has a transmittance of at least 85%, more preferably at least 90%, and even at least 90%, for a detection signal with an angle of incidence of 55°-70°, so as to ensure that the detector 200 in the vehicle can operate normally and have relatively high detection accuracy. The angle of incidence is an angle between an incident detection signal and a normal of the signal transmission region Q1.

Specifically, the wavelength of the detection signal ranges from 380 nm to 1650 nm or from 3 mm to 30 mm. For example, the detector 200 may be a visible-light camera (380 nm-780 nm), a near-infrared camera (780 nm-1650 nm), a LiDAR (also known as light detection and ranging) (905 nm and 1550 nm), or a millimeter-wave radar (3 mm-30 mm), and is used for imaging, ranging, positioning, etc. It may be noted that the number of the signal transmission regions Q1 may be one or more, and may be set according to actual requirements.

Specifically, the detection signal may be circularly polarized light, P-polarized light, or mixed light of P-polarized light and S-polarized light and a proportion of the P-polarized light in the mixed light is greater than or equal to 50%. For a LiDAR, due to high requirements for vehicle safety, the transmittance of the signal transmission region Q1 for a detection signal from the LiDAR must be higher. The angle of incidence of the detection signal is approximately equal to a Brewster's angle of P-polarized light incident onto laminated glass, and preferably, the detection signal from the LiDAR is the P-polarized light or the mixed light with the proportion of the P-polarized light greater than or equal to 80%.

The wave transparent layer 120 is carried on the laminated glass 110. The orthographic projection of the wave transparent layer 120 on the laminated glass 110 covers the signal transmission region Q1. Due to the wave transparent layer 120, the transmittance of the signal transmission region Q1 for the detection signal with the angle of incidence of 55°−70° C. an be improved. The transmittance is measured and calculated according to International Organization for Standardization (ISO) 9050 when the detection signal is incident at the angle of incidence of 55°-70°. Preferably, for the detection signal with the angle of incidence of 55°-70°, the transmittance of the signal transmission region Q1 when the wave transparent layer 120 is present is at least 3%, more preferably at least 5%, even at least 8% higher than the transmittance of the signal transmission region Q1 when the wave transparent layer 120 is absent.

The orthographic projection of the wave transparent layer 120 on the laminated glass 110 further covers the non-signal transmission region Q2. In addition, an area of the orthographic projection of the wave transparent layer 120 on the laminated glass 110 accounts for more than 70%, such as 70%, 80%, 90%, 95%, 100%, etc., of an area of the laminated glass 110. Therefore, after the wave transparent layer 120 is deposited on the laminated glass 110, there is no need to remove a part of the wave transparent layer 120 corresponding to the non-signal transmission region Q2. Therefore, in addition to ensuring that the transmittance of the signal transmission region Q1 for the detection signal is improved, the process difficulty is greatly reduced and the production efficiency is improved.

The thermal insulation layer 130 is carried on the laminated glass 110. The orthographic projection of the thermal insulation layer 130 on the laminated glass 110 covers the non-signal transmission region Q2 and does not cover the signal transmission region Q1. In other words, after the thermal insulation layer 130 is deposited on the laminated glass 110, only a part of the thermal insulation layer 130 corresponding to the signal transmission region Q1 needs to be removed, to ensure that the transmittance of the signal transmission region Q1 for the detector signal is not reduced due to the part of thermal insulation layer 130 corresponding to the signal transmission region Q1. It may be noted that after the thermal insulation layer 130 is deposited on the laminated glass 110 and a coating removal operation is performed, the orthographic 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 addition, an area of the orthographic projection of the thermal insulation layer 130 on the laminated glass 110 accounts for more than 70% of the area of the laminated glass 110. The thermal insulation layer 130 reflects or absorbs near-infrared light, so that the non-signal transmission region Q2 of the laminated glass 110 has a heat insulation effect.

An area of an overlap region between the orthographic projection of the wave transparent layer 120 on the laminated glass 110 and the orthographic projection of the thermal insulation layer 130 on the laminated glass 110 accounts for at least 80% of the area of the orthographic projection of the thermal insulation layer 130 on the laminated glass 110. Specifically, the laminated glass 110 has a total solar energy transmittance equal to or less than 53% in the overlap region between the orthographic projection of the wave transparent layer 120 on the laminated glass 110 and the orthographic projection of the thermal insulation layer 130 on the laminated glass 110. The signal transmission region Q1 has a transmittance of at least 85% for a detection signal with a wavelength range of 380 nm-1650 nm or 3 mm-30 mm and an angle of incidence of 55°-70°. Without removing the part of the wave transparent layer 120 corresponding to the non-signal transmission region Q2, the laminated glass 110 can still be ensured to have an effective heat insulation effect.

The laminated glass assembly 100 provided in the present disclosure includes the laminated glass 110, the wave transparent layer 120, and the thermal insulation layer 130. The laminated glass 110 has the signal transmission region Q1 and the non-signal transmission region Q2. The wave transparent layer 120 is carried on the laminated glass 110. The orthographic projection of the 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 carried on the laminated glass 110. The orthographic 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. For the laminated glass assembly provided in the present disclosure, the part of the thermal insulation layer 130 corresponding to the signal transmission region Q1 is removed, and the wave transparent layer 120 covers the signal transmission region Q1 and the non-signal transmission region Q2. Therefore, in addition to a heat insulation function of the laminated glass assembly 100, the transmittance of the signal transmission region Q1 for the detection signal is also improved, so that the laminated glass assembly 100 in the present disclosure has both the heat insulation function and the local high infrared-light transmittance function.

In an implementation, the laminated glass 110 includes 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 opposite to the first surface 1111. The second transparent substrate 1120 has a third surface 1121 and a fourth surface 1122 opposite to the third surface 1121. The third surface 1121 is closer to the second surface 1112 than the fourth surface 1122. The adhesive film 1130 is for adhering the first transparent substrate 1110 and the second transparent substrate 1120.

In this implementation, the intermediate adhesive film 1130 may be polyvinyl butyral (PVB), an ionic adhesive film (e.g., SentryGlass® Plus (SGP)), ethylene vinyl acetate (EVA), polyurethane (PU), or the like, as long as the intermediate adhesive film 1130 can tightly adhere the first transparent substrate 1110 and the second transparent substrate 1120 together.

The following describes an application scenario of the laminated glass 110. When the laminated glass 110 is applied to a vehicle, the laminated glass 110 is mounted on the vehicle at a certain angle of inclination to serve as a windshield. The first transparent substrate 1110 of the laminated glass 110 serves as a substrate of the laminated glass 110 exposed outside the vehicle. The second transparent substrate 1120 serves as a substrate of the laminated glass 110 inside the vehicle.

In an implementation, under ISO 9050, the first transparent substrate 1110 has a vertical visible-light transmittance TL greater than or equal to 88%. In another implementation, under ISO 9050, the first transparent substrate 1110 has the vertical visible-light transmittance TL greater than or equal to 90%. In yet another implementation, under ISO 9050, the first transparent substrate 1110 has the vertical visible-light transmittance TL greater than or equal to 92%. The visible-light transmittance of the laminated glass 110 is ensured, so that a field of view (FOV) is sharper through the laminated glass 110.

For example, the first transparent substrate 1110 may be soda-lime-silica glass, high-alumina glass, borosilicate glass, or the like, and the second transparent substrate 1120 may be high-alumina glass or borosilicate glass. Therefore, the strength of the laminated glass 110 is ensured, and the laminated glass 110 can withstand an impact with a certain strength. Meanwhile, a thickness d1 of the first transparent substrate 1110 satisfies: 1.6 mm≤d1≤4 mm. A thickness d2 of the second transparent substrate 1120 satisfies: 0.3 mm≤d2≤2.3 mm. A total thickness d of the laminated glass 110 after being laminated satisfies: d≥4.2 mm. Therefore, the laminated glass 110 can be ensured to be suitable for different light weight requirements.

In other implementations, the laminated glass 110 has multiple transparent substrates, and correspondingly has multiple adhesive films 1130 to tightly adhere the transparent substrates together. In the present disclosure, for example, the laminated glass 110 has two transparent substrates.

It may be noted that in the present disclosure, a thickness of the wave transparent layer 120 and a thickness of the thermal insulation layer 130 are both in nm level, which cannot be distinguished by human eyes. In addition, the first transparent substrate 1110, the second transparent substrate 1120, the wave transparent layer 120, the thermal insulation layer 130, and the adhesive film 1130 are closed connected without gaps. Therefore, in order to describe the structure of the laminated glass assembly 100 more clearly, in the accompanying drawings of the laminated glass assembly 100 in the present disclosure, the thickness of each component is increased and various components are separated to illustrate the layered structure. The following describes a specific structure of the laminated glass assembly 100.

Reference can be to FIG. 1, FIG. 2, FIG. 3, and FIG. 4 together, where FIG. 2 is a cross-sectional view of a layered structure taken along line A-A in FIG. 1 according to an implementation of the present disclosure, FIG. 3 is a cross-sectional view of a layered structure taken along line A-A in FIG. 1 according to another implementation of the present disclosure, and FIG. 4 is a cross-sectional view of a layered structure taken along line A-A in FIG. 1 according to yet another implementation of the present disclosure. In an implementation, the second transparent substrate 1120, the adhesive film 1130, and the thermal insulation layer 130 all define through holes 140 in communication with one another. At least a part of each of the through holes 140 is located in the signal transmission region Q1. In other words, the thermal insulation layer 130 defines a first through hole 141, the adhesive film 1130 defines a second through hole 142, and the second transparent hole 1120 defines a third through hole 143. The through holes 140 include the first through hole 141, the second through hole 142, and the third through hole 143. The first through hole 141, the second through hole 142, and the third through hole 143 are in communication with each other. At least part of each of the first through hole 141, the second through hole 142, and the third through hole 143 is located in the signal transmission region Q1. The wave transparent layer 120 is disposed on the second surface 1112. The thermal insulation layer 130 is disposed on a surface of the wave transparent layer 120 close to the second transparent substrate 1120 (as illustrated in FIG. 2), or the thermal insulation layer 130 is disposed on the third surface 1121 (as illustrated in FIG. 3), or the thermal insulation layer 130 is disposed in the adhesive film 1130 (as illustrated in FIG. 4).

In this implementation, at least the part of each through hole 140 is located in the signal transmission region Q1. In other words, the through hole 140 may be not only located in the signal transmission region Q1 but also located in the non-signal transmission region Q2. The detection signal from the detector 200 is transmitted through the through hole 140, the wave transparent layer 120, and the first transparent substrate 1110, but is not transmitted through the second transparent substrate 1120, the adhesive film 1130, and the thermal insulation layer 130. Therefore, the second transparent substrate 1120, the adhesive film 1130, and the thermal insulation layer 130 are avoided from blocking the detection signal. The selection of the second transparent substrate 1120, the adhesive film 1130, and the thermal insulation layer 130 is freer. For example, the second transparent substrate 1120 may be tinted glass. The adhesive film 1130 may be an adhesive film with a heat insulation performance. The thermal insulation layer 130 may be a thermal insulation layer with a higher performance. Therefore, the product mix of the laminated glass is more diversified.

In this implementation, the wave transparent layer 120 is disposed on the second surface 1112. The wave transparent layer 120 having a high signal transmission function may be deposited on the second surface 1112 by means of physical vapor deposition (PVD), chemical vapor deposition (CVD), or the like, thereby improving the transmittance of the signal transmission region Q1 for the detection signal.

In this implementation, the thermal insulation layer 130 is disposed on the surface of the wave transparent layer 120 close to the second transparent substrate 1120 (as illustrated in FIG. 2), or the thermal insulation layer 130 is disposed on the third surface 1121 (as illustrated in FIG. 3), or the thermal insulation layer 130 is disposed in the adhesive film 1130 (as illustrated in FIG. 4). The thermal insulation layer 130 may be directly deposited on the surface of the wave transparent layer 120 close to the second transparent substrate 1120 or on the third surface 1121 by means of PVD, CVD, sol-gel spraying, or the like. Alternatively, the thermal insulation layer 130 may be deposited on the polymer film, such as polyethylene terephthalate (PET), and then interlaid into the adhesive film 1130 as a part of the adhesive film 1130.

The following are implementations of the orthographic projection of the thermal insulation layer 130 on the laminated glass 110 avoiding the signal transmission region Q1. In an implementation, firstly, the thermal insulation layer 130 may be deposited on the surface of the wave transparent layer 120 close to the second transparent substrate 1120 or on the third surface 1121, or the thermal insulation layer 130 may be deposited on a polymer film and then interlaid into the adhesive film 1130 as the part of the adhesive film 1130. Then, the part of the thermal insulation layer 130 corresponding to the signal transmission region Q1 is removed. In another implementation, firstly, a part of the surface of the wave transparent layer 120, close to the second transparent substrate 1120 and corresponding to the signal transmission region Q1, is covered by a masking layer, or a part of the third surface 1121 corresponding to the signal transmission region Q1 is covered by the masking layer. Then, the thermal insulation layer 130 is deposited on the surface of the wave transparent layer 120 close to the second transparent substrate 1120 or on the third surface 1121. Finally, the masking layer is removed. Alternatively, firstly, a part of the polymer film corresponding to the signal transmission region Q1 is covered by the masking layer. Then after the thermal insulation layer 130 is deposited on the polymer film, the masking layer is removed. Finally, the thermal insulation layer 130 is interlaid into the adhesive film 1130. Therefore, the heat insulation effect of the laminated glass 110 can be maintained without affecting the transmittance of the signal transmission region Q1 for the detection signal.

In this implementation, the wave transparent layer 120 is configured to improve the transmittance of the signal transmission region Q1 for the detection signal with the angle of incidence of 55°-70°. The wave transparent layer 120 has at least one laminated structure including a high refractive-index layer and a low refractive-index layer. The high refractive-index layer has a refractive index of 1.9-2.6. The low refractive-index layer has a refractive index of 1.3-1.8. With the design of the at least one laminated structure including the high refractive-index layer and the low refractive-index layer, the transmittance is improved. The high refractive-index layer may have multiple sub-layers, and/or the low refractive-index layer may also have multiple sub-layers. The high refractive-index layer and the low refractive-index layer are different in at least one of a material of each sub-layer, a thickness of each sub-layer, or a refractive index of each sub-layer. The thermal insulation layer 130 is configured to reflect and/or absorb infrared light, so that the laminated glass has a good heat insulation effect. The thermal insulation layer 130 includes at least one of metallic silver layer, a silver alloy layer, or a transparent conductive oxide (TCO) layer. The metallic silver layer, the silver alloy layer, or the TCO layer has a good infrared-light reflection performance, thereby reducing the transmittance of the laminated glass for infrared light. The material of the silver alloy layer is preferably made of a silver-copper alloy, a silver-indium alloy, a silver-gold alloy, etc. A silver content in the silver alloy layer is preferably greater than or equal to 95%, more preferably greater than or equal to 98%. The TCO layer includes at least one TCO layer, 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), etc. The thermal insulation layer 130 may further include other dielectric layers.

In the related art, in order to additionally dispose a signal transmission region capable of improving a signal transmittance on thermal insulation glass, implementations are usually as follows. After a wave transparent layer is deposited on the whole surface of glass by means of magnetron sputtering, a part of the wave transparent layer deposited corresponding to a non-signal transmission region is removed. Alternatively, firstly, a part of the glass corresponding to the non-signal transmission region is covered by a masking layer, then the wave transparent layer is deposited on the glass, and finally, the masking layer is removed. However, since the area of the orthographic projection of the non-signal transmission region on the glass accounts for more than 80% of the area of the region where the glass is located, in the related art, an additional coating removal process for the signal transmission region with a small area proportion is not ideal in terms of production efficiency and process complexity. As a result, the quality cost of the batch production process remains high.

Compared to the related art, for example, specifically (as illustrated in FIG. 2), under ISO 9050, a vertical visible-light transmittance TL of the first transparent substrate 1110 is 89.9%. ZnSnO_x with a thickness of 92 nm, TiO_x with a thickness of 7 nm, SiO₂ with a thickness of 117 nm, and TiO_x with a thickness of 25 nm are sequentially deposited on the second surface 1112 to form the wave transparent layer 120. Then, on the surface of the wave transparent layer 120 close to the second transparent substrate 1120, AZO with a thickness of 11 nm, Ag with a thickness of 12.8 nm, TiO_x with a thickness of 9 nm, ZnSnO_x with a thickness of 60 nm, AZO with a thickness of 20 nm, Ag with a thickness of 9.2 nm, TiO_x with a thickness of 9 nm, AZO with a thickness of 8 nm, ZnSnO_x with a thickness of 10 nm, and Si₃N₄ with a thickness of 10 nm are sequentially deposited, to form the thermal insulation layer 130. In addition, a part of the thermal insulation layer 130 corresponding to the signal transmission region Q1 is removed. Experimental tests are performed on the laminated glass assembly 100 that is mounted on a vehicle 1 at an angle α of 60°. A vertical visible-light transmittance TL of the laminated glass assembly 100 is 75.6% in the overlap region between the orthographic projection of the wave transparent layer 120 on the laminated glass 110 and the orthographic projection of the thermal insulation layer 130 on the laminated glass 110. The laminated glass assembly 100 has a reflectivity RL of 14.1% for visible light incident onto the fourth surface 1122 in the overlap region between the orthographic projection of the wave transparent layer 120 on the laminated glass 110 and the orthographic projection of the thermal insulation layer 130 on the laminated glass 110. The laminated glass assembly 100 has a total solar energy transmittance TTS of 51.3% in the overlap region between the orthographic projection of the wave transparent layer 120 on the laminated glass 110 and the orthographic projection of the thermal insulation layer 130 on the laminated glass 110.

For a detection signal with a wavelength of 905 nm and an angle of incidence of 60°, a transmittance Ts1 of the signal transmission region Q1 is 87.04%, which is increased by 5.54% compared to a transmittance Ts2 of a signal transmission region Q1 without depositing the wave transparent layer 120. It can be concluded from experimental tests that in this implementation, the heat can be effectively insulated due to the arrangement of the thermal insulation layer 130, the transmittance of the signal transmission region Q1 for the signal can be effectively improved due to the arrangement of the wave transparent layer 120, and a color appearance that can be comfortable to human eyes, such as light blue, can also be presented due to the overlap arrangement between the thermal insulation layer 130 and the wave transparent layer 120.

In this implementation (as illustrated in FIG. 2), only the part of the thermal insulation layer 130 corresponding to the signal transmission region Q1 needs to be removed, and the part of the wave transparent layer 120 corresponding to the non-signal transmission region Q2 does not need to be removed, so that the manufacturing process is simpler. Therefore, the laminated glass assembly 100 in the present disclosure has both the heat insulation function and the local high infrared-light transmittance function, and is manufactured with high efficiency. Meanwhile, in this implementation, a part of the wave transparent layer 120 can serve as a base of the thermal insulation layer 130. During processing and forming of the laminated glass assembly 100, the wave transparent layer 120 can effectively prevent alkali metal ions in the first transparent substrate 1110 from freeing into the thermal insulation layer 130. Therefore, there is no need to additionally dispose a base film layer to protect the thermal insulation layer, and the heat insulation function of the thermal insulation layer 130 can be ensured not to be impaired during the manufacturing process of the laminated glass 100. Further, the wave transparent layer 120 can also play a role of color adjustment. A process of sequentially and continuously depositing the wave transparent layer 120 and the thermal insulation layer 130 on the second surface 1112 is efficient and simple, so that the laminated glass assembly 100 has both the heat insulation function and the local high infrared-light transmittance function, and is manufactured with high efficiency.
