Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a vehicle window glass and a vehicle. Background Art

[0002] With the continuous advancement of technology, modern vehicles are widely equipped with various types of optical sensors, such as LiDAR systems and near-infrared cameras, to enable functions such as navigation and autonomous driving. These optical sensors can be installed inside the vehicle and protected by window glass. Therefore, the window glass must have a high transmittance for optical sensor signals. In other words, window glass typically uses a combination of high-transmittance glass and high-transmittance glass to ensure smooth transmission of optical sensor signals.

[0003] However, there is a certain color difference between this high-transmittance glass combination and traditional glass combinations (such as green glass + white glass, green glass + green glass, etc.). This color difference will cause the high-transmittance glass combination to be applied to automobiles, which may easily have an adverse effect on the appearance and user experience of the car. Summary of the Invention

[0004] The embodiments of the present application provide a vehicle window glass and a vehicle, which can improve the color consistency between the high-transmittance glass combination and the traditional glass combination, thereby enhancing the aesthetics of the vehicle.

[0005] In a first aspect, the present application provides a vehicle window glass, comprising a glass body and a colored layer, wherein the glass body has a signal transmission area;

[0006] The glass body comprises an outer glass plate, an intermediate layer and an inner glass plate stacked in sequence, wherein the intermediate layer is connected between the outer glass plate and the inner glass plate;

[0007] The outer glass plate and the inner glass plate are both high-transmittance glass;

[0008] The colored layer is located between the outer glass sheet and the inner glass sheet, and / or is located on the side of the inner glass sheet facing away from the intermediate layer;

[0009] The colored layer is used to block near infrared rays and / or ultraviolet rays.

[0010] It is understood that optical sensors can be installed inside a vehicle and protected by window glass to avoid the influence of the external environment (such as dust, rain, snow, or frost). In this case, the window glass needs to have a high transmittance for the signals transmitted and received by the optical sensor to ensure smooth transmission of the optical sensor signals. For example, because the wavelength band of LiDAR signals is close to the near-infrared band, vehicles with built-in LiDARs typically use glass materials with high near-infrared transmittance as window glass. In other words, the window glass typically uses a combination of high-transmittance glass + high-transmittance glass (such as ultra-clear glass + ultra-clear glass). However, there is a certain color difference between this high-transmittance glass combination and traditional glass combinations (such as green glass + white glass, green glass + green glass, etc.). When a high-transmittance glass combination is used simultaneously with a traditional glass combination in the same vehicle, or when a high-transmittance glass combination is used simultaneously with a traditional glass combination in vehicles of the same series but with different configurations, the color difference between the high-transmittance glass combination and the traditional glass combination may affect the vehicle's appearance.

[0011] Based on this, in the embodiments of the present application, since both the outer and inner glass panels are high-transmittance glass, compared to ordinary glass, high-transmittance glass has a higher light transmittance, presenting a clearer and more transparent visual effect. Therefore, by providing a colored layer in the vehicle window glass, the color of the colored layer can directly affect the displayed color of the vehicle window glass. Moreover, by adjusting the color of the colored layer, the color of the vehicle window glass can be precisely adjusted, thereby reducing the color difference between the high-transmittance glass combination and the traditional glass combination in the same vehicle (or vehicles of the same series but different configurations), maintaining color consistency between them, and thus improving the overall aesthetics of the vehicle.

[0012] In a possible implementation manner, in the Lab values of the reflected color of the vehicle window glass measured from the outside of the vehicle, the a value is less than -2.6, and the b value is -9.04 to -0.28.

DETAILED DESCRIPTION

[0072] For ease of understanding, the terms involved in the embodiments of the present application are first explained.

[0073] And / or: It is just a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0076] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. It should be noted that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0077] Embodiments of the present application provide a vehicle window glass and a vehicle.

[0078] See also Figure 1 , Figure 1 It is a structural schematic diagram of a vehicle 200 provided in an embodiment of the present application.

[0079] Vehicle 200 may include a window glass 100, a body sheet metal 210, and an optical sensor 220. The window glass 100 is mounted on the body sheet metal 210 and, together with the body sheet metal 210, forms a housing for the vehicle 200. The optical sensor 220 is located within the housing for the vehicle 200. Signals transmitted or received by the optical sensor 220 may be transmitted through the window glass 100. The window glass 100 may be one or more of the front windshield, rear windshield, sunroof, side windows, or corner windows of the vehicle 200. The optical sensor 220 may be one or a combination of a laser radar, a near-infrared camera, a visible light camera, a thermal imager, and the like.

[0080] It should be noted that Figure 1 The purpose of this illustration is merely to schematically illustrate the connection relationship between the vehicle window glass 100, the vehicle body sheet metal 210, and the optical sensor 220, and is not intended to limit the connection locations, specific structures, or quantities of the individual components. In other embodiments of the present application, the vehicle 200 may include more or fewer components than shown, or may combine or separate certain components, or may have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of both.

[0081] The following description will be given by taking the vehicle window glass 100 as the front windshield of the vehicle 200 and the optical sensor 220 as a laser radar as an example, but it should be understood that the present invention is not limited to this.

[0082] It is understood that the LiDAR can be installed inside the vehicle and protected by the window glass to avoid the influence of the external environment (such as dust, rain, snow, or frost). In this case, the window glass needs to have a high transmittance for the signals transmitted and received by the LiDAR to ensure smooth transmission of the LiDAR signals. Currently, because the wavelength band of the LiDAR signal is close to the near-infrared band, vehicles with built-in LiDAR generally use glass materials with high near-infrared transmittance as the window glass. In other words, the window glass usually adopts a combination of high-transmittance glass + high-transmittance glass (such as ultra-clear glass + ultra-clear glass). However, there is a certain color difference between this high-transmittance glass combination and traditional glass combinations (such as green glass + white glass, green glass + green glass, etc.). When a high-transmittance glass combination and a traditional glass combination are used in the same vehicle, for example, a high-transmittance glass combination is used for the front windshield and a traditional glass combination is used for the side windows, this color difference will affect the overall appearance of the vehicle and the user experience. Similarly, when high-transmittance glass combinations and traditional glass combinations are used simultaneously in cars of the same series but with different configurations, for example, the front windshield of a car with relatively higher configurations uses a high-transmittance glass combination, while the front windshield of a car with relatively lower configurations uses a traditional glass combination, the color difference between the high-transmittance glass combination and the traditional glass combination will also affect the appearance of the car and user experience.

[0083] Based on this, the embodiment of the present application provides a vehicle window glass 100 that can improve the color consistency between the high-transmittance glass combination and the traditional glass combination, thereby enhancing the overall aesthetics of the vehicle 200. It should be noted that the optical sensor 220 signals described below refer to lidar signals.

[0084] It is understood that the high-transmittance glass in the present application refers to glass with a transmittance of near-infrared rays within the wavelength range of 800nm-1600nm (including the endpoints 800nm and 1600nm) greater than or equal to 90%.

[0085] The structure of the vehicle window glass 100 will be described in detail below through eight specific embodiments.

[0086] First embodiment:

[0087] Please refer to Figure 1 and Figure 2 , Figure 2 It is along Figure 1 The section line AA shown is a first schematic cross-sectional view of a partial structure of the vehicle window glass 100 of the first embodiment.

[0088] For ease of description, the length direction of the window glass 100 is defined as the X direction, the width direction of the window glass 100 is defined as the Y direction, and the thickness direction of the window glass 100 is defined as the Z direction. The X direction, the Y direction, and the Z direction are perpendicular to each other.

[0089] The vehicle window glass 100 may include a glass body 10 and a colored layer 20. The colored layer 20 is connected to the glass body 10 and is used to adjust the color of the vehicle window glass 100. The glass body 10 has a signal transmission area 11 (such as Figure 2 (as shown in the area between the two dashed lines in FIG. 1 ). The signal transmission area 11 is the area on the vehicle window glass 100 through which the optical sensor 220 signal can pass. The optical sensor 220 signal may be the signal transmitted and received by the optical sensor 220. In other words, all signals transmitted or received by the optical sensor 220 pass through the signal transmission area 11 on the vehicle window glass 100.

[0090] The glass body 10 may include an outer glass sheet 12, an intermediate layer 13, and an inner glass sheet 14. The intermediate layer 13 is connected between the outer glass sheet 12 and the inner glass sheet 14. Specifically, the outer glass sheet 12, the intermediate layer 13, and the inner glass sheet 14 are stacked in sequence along the thickness direction (Z direction in the figure) of the glass body 10. The outer glass sheet 12 is positioned toward the exterior of the vehicle 200, while the inner glass sheet 14 is positioned toward the interior of the vehicle 200.

[0091] In this embodiment, the outer glass plate 12 has a high near-infrared transmittance. That is, the outer glass plate 12 can be high-transmittance glass. Preferably, the outer glass plate 12 is ultra-clear glass (i.e., ultra-transparent glass).

[0092] In one possible embodiment, the vertical transmittance of near-infrared light with a wavelength in the range of 800 nm to 1600 nm (inclusive) through the outer glass plate 12 is greater than or equal to 90%. Specifically, the vertical transmittance of near-infrared light with a wavelength in the range of 840 nm to 940 nm (inclusive) through the outer glass plate 12 is greater than or equal to 90%. The vertical transmittance of near-infrared light through the outer glass plate 12 refers to the transmittance of near-infrared light when it is perpendicularly incident on the outer glass plate 12, that is, the transmittance of the near-infrared light passing through the outer glass plate 12 along the thickness direction of the outer glass plate 12 (the Z direction in the figure). For example, the vertical transmittance of near-infrared light with a wavelength of 905 nm through the outer glass plate 12 is greater than or equal to 90%.

[0093] In this embodiment, specifically, the vertical transmittance of near-infrared rays with a wavelength in the range of 1500 nm to 1600 nm (including the endpoints 1500 nm and 1600 nm) through the outer glass plate 12 is also greater than or equal to 90%. For example, the vertical transmittance of near-infrared rays with a wavelength of 1550 nm through the outer glass plate 12 is greater than or equal to 90%.

[0094] In this embodiment, the inner glass plate 14 also has a high near-infrared transmittance. That is, the inner glass plate 14 can be a high-transmittance glass. Preferably, the inner glass plate 14 is ultra-clear glass (i.e., ultra-transparent glass).

[0095] In one possible embodiment, the vertical transmittance of near-infrared light with a wavelength in the range of 800 nm to 1600 nm (inclusive) through the inner glass sheet 14 is greater than or equal to 90%. Specifically, the vertical transmittance of near-infrared light with a wavelength in the range of 840 nm to 940 nm (inclusive) through the inner glass sheet 14 is greater than or equal to 90%. The vertical transmittance of near-infrared light through the inner glass sheet 14 is the transmittance of near-infrared light when it is perpendicularly incident on the inner glass sheet 14, that is, the transmittance of the near-infrared light passing through the inner glass sheet 14 along the thickness direction of the inner glass sheet 14 (the Z direction in the figure). For example, the vertical transmittance of near-infrared light with a wavelength of 905 nm through the inner glass sheet 14 is greater than or equal to 90%.

[0096] In this embodiment, specifically, the vertical transmittance of near-infrared rays with a wavelength in the range of 1500 nm to 1600 nm (including the endpoints 1500 nm and 1600 nm) through the inner glass plate 14 is also greater than or equal to 90%. For example, the vertical transmittance of near-infrared rays with a wavelength of 1550 nm through the inner glass plate 14 is greater than or equal to 90%.

[0097] In this embodiment, because the wavelength of the optical sensor 220 signal (i.e., the lidar signal) is close to the near-infrared wavelength, both the outer glass plate 12 and the inner glass plate 14 have high transmittance for the optical sensor 220 signal. For example, the vertical transmittance of the optical sensor 220 signal with a wavelength of 905 nm is greater than or equal to 90% on both the outer glass plate 12 and the inner glass plate 14. The vertical transmittance of the optical sensor 220 signal with a wavelength of 1550 nm is greater than or equal to 90% on both the outer glass plate 12 and the inner glass plate 14.

[0098] It can be understood that by making the outer glass plate 12 and the inner glass plate 14 have a higher transmittance to the optical sensor 220 signal, the problem of the optical sensor 220 signal being blocked by the outer glass plate 12 and the inner glass plate 14 can be avoided, so that the optical sensor 220 can effectively detect the target and maintain its detection accuracy.

[0099] In this embodiment, the colored layer 20 is connected between the outer glass pane 12 and the intermediate layer 13. Alternatively, the colored layer 20 is connected between the intermediate layer 13 and the inner glass pane 14. The colored layer 20 is used to adjust the color of the window glass 100 and block near-infrared radiation. The projection of the colored layer 20 onto the glass body 10 along the thickness direction of the glass body 10 is offset from the signal-transmitting area 11.

[0100] The colored layer 20 is a single-layer structure. For example, the colored layer 20 may be a near-infrared reflective (IRR) coating layer. The near-infrared transmittance of the colored layer 20 is less than or equal to 20%. The total solar transmittance (TTS) of the area covered by the colored layer 20 in the vehicle window glass 100 is less than or equal to 55%.

[0101] It is understood that because the outer glass pane 12 has a high near-infrared transmittance, the near-infrared shielding capability of the vehicle window glass 100 needs to be enhanced to prevent heat accumulation caused by near-infrared radiation. Therefore, this embodiment effectively blocks near-infrared radiation by disposing a colored layer 20 with a high near-infrared reflectivity between the outer glass pane 12 and the intermediate layer 13 and / or between the intermediate layer 13 and the inner glass pane 14. This prevents the increase in vehicle interior temperature caused by excessive near-infrared transmittance of the outer glass pane 12, thereby improving the thermal insulation performance and comfort of the vehicle 200.

[0102] It can be understood that since the wavelength band of the optical sensor 220 signal is close to the wavelength band of near-infrared rays, in order to avoid the colored layer 20 hindering the transmission of the optical sensor 220 signal, this embodiment staggers the projection of the colored layer 20 on the glass body 10 along the thickness direction of the glass body 10 with the signal transmission area 11, which can effectively block the near-infrared rays from penetrating the vehicle window glass 10 without affecting the normal passage of the optical sensor 220 signal through the vehicle window glass 100, so that the optical sensor 220 can perform effective detection and work normally.

[0103] For a possible implementation, see Figure 2 The colored layer 20 is a single-layer structure. It is connected between the outer glass plate 12 and the intermediate layer 13. Its projection on the glass body 10 along the thickness direction of the glass body 10 is offset from the signal transmission area 11. This allows the optical sensor 220 signal to avoid the colored layer 20 on the window glass 100 when passing through it.

[0104] This embodiment further provides five examples and two comparative examples to explore the performance of the vehicle window glass 100 of this embodiment.

Both the outer glass sheet 12 and the inner glass sheet 14 are ultra-clear glass. The colored layer 20 is connected between the outer glass sheet 12 and the intermediate layer 13 and is used to adjust the color of the vehicle window glass 100 and block near-infrared radiation.

[0116] The vehicle window glass 100 provided in Comparative Example 1 comprises only a glass body 10. The glass body 10 comprises an outer glass sheet 12, an intermediate layer 13, and an inner glass sheet 14, stacked in sequence. Both the outer glass sheet 12 and the inner glass sheet 14 are green glass. The reflected color Lab values of the vehicle window glass 100, measured from the vehicle exterior, have an L value of 34.80, an a value of -2.60, and a b value of -0.28.

[0117] Comparative Example 2:

[0118] Comparative Example 2 provides a vehicle window glass 100 comprising only a glass body 10. The glass body 10 comprises an outer glass sheet 12, an intermediate layer 13, and an inner glass sheet 14, stacked in sequence. One of the outer glass sheet 12 and the inner glass sheet 14 is green glass, and the other is clear glass. The reflected color Lab values of the vehicle window glass 100, measured from the vehicle exterior, have an a value of -3.45 and a b value of -9.04.

[0119] The window glasses 100 of Examples 1-5 and Comparative Examples 1-2 were respectively integrated with the optical sensor 220 to measure the L value, a value, and b value of the Lab value of the reflected color of the window glasses 100, as well as the Y value and visible light transmittance TL from the outside of the vehicle.

[0120] Among them, visible light transmittance TL: calculated according to ISO9050.

[0121] The Lab value of the reflected color of the window glass 100 refers to the Lab value of the reflected color of the window glass 100 measured from the vehicle exterior.

[0122] The L, a, and b values in the Lab value of reflected color: In the field of color measurement and analysis, Lab values are commonly used to calculate color difference. The L value is a lightness value used to indicate the brightness of glass, and its range is [0, 100], representing pure black to pure white. The a and b values are both color values. The a value represents the range from red to green, and its range is [127, -128]. The b value represents the range from yellow to blue, and its range is [127, -128].

[0123] Y value: represents the reflectance and transmittance of visible light. The range of Y value is [0, 100].

[0124] The measurement results of Comparative Examples 1-2 and Examples 1-5 are recorded in Table 1.

[0125] Table 1: Measurement results of the vehicle window glasses 100 of Comparative Examples 1-2 and Examples 1-5

[0126]

[0127] Based on test data from multiple sets of embodiments, in the Lab values of the reflected color of the vehicle window glass 100 measured from the vehicle exterior, the a value can be less than -2.6, such as -3.88, -5.16, -6.64, -8.74, -9.79, etc. The b value is within the range of -9.04 to -0.28, including endpoints of -9.04 and -0.28, such as -6.32, -5.71, -5.38, -3.90, -3.39, etc. Furthermore, in the Lab values of the reflected color of the vehicle window glass 100 measured from the vehicle exterior, the a value can be less than -3.45, and the b value is within the range of -9.04 to -0.28, including endpoints of -9.04 and -0.28.

[0128] Specifically, the Lab value a of the window glass 100, measured from the outside of the vehicle, is lower than that of conventional glass combinations, while the b value lies between the b values of the green glass + green glass combination and the b value of the green glass + white glass combination. In color evaluation, a and b values within this range make the color of the window glass 100 made using the high-transmittance glass combination closer to that of the window glass 100 made using the conventional glass combination. In other words, a and b values within this range are more effective in reducing the color difference between the high-transmittance glass combination and the conventional glass combination, achieving color consistency between the two.

[0129] Furthermore, based on test data from multiple sets of embodiments, the L value can be within the range of 39.39 to 44, including the endpoints of 39.39 and 44. For example, the L value can be 39.39, 40.55, 41.69, 43.54, 44, etc. Within this range, the L value can maintain appropriate transparency for the vehicle window glass 100 without appearing too dark or too transparent.

[0130] In addition, the test results of the five sets of embodiments show that the visible light transmittance of the vehicle window glass 100 is greater than 80%. The Y value is also greater than the Y value of the traditional glass combination, indicating that the vehicle window glass 100 has high transparency.

[0131] In summary, it can be understood that in this embodiment, both the outer glass plate 12 and the inner glass plate 14 are high-transmittance glass. Compared to ordinary glass, high-transmittance glass has a higher light transmittance, presenting a clearer and more transparent visual effect. Therefore, by providing a colored layer 20 in the vehicle window glass 100, the color of the colored layer 20 can directly affect the display color of the vehicle window glass 100. Moreover, by adjusting the colored layer 20, and thereby adjusting the Lab value of the reflected color of the vehicle window glass 100, the color of the vehicle window glass 100 can be precisely adjusted, thereby reducing the color difference between the high-transmittance glass combination and the traditional glass combination in the same vehicle 200 (or vehicles 200 of the same series but different configurations), maintaining color consistency between them, and improving the overall aesthetics of the vehicle 200.

[0132] Furthermore, it will be appreciated that in this embodiment, to improve the transmittance of the optical sensor 220 signal through the window glass 100, both the outer glass panel 12 and the inner glass panel 14 are constructed from high-transmittance glass with high near-infrared transmittance. However, compared to conventional window glass 100, this high-transmittance glass with high near-infrared transmittance often also has increased ultraviolet transmittance, leading to a higher probability and risk of ultraviolet rays passing through the window glass 100 and damaging the optical sensor 220. Therefore, this embodiment requires enhanced ultraviolet resistance for the window glass 100. The following describes how this embodiment enhances the ultraviolet resistance of the window glass 100 through three specific application scenarios.

[0133] In the first possible application scenario, please continue to refer to Figure 2 , the intermediate layer 13 can be configured as a layer that enhances UV absorption. Specifically, in this application scenario, the intermediate layer 13 can absorb UV rays with a wavelength less than or equal to 410 nm, and the transmittance of UV rays with a wavelength less than or equal to 410 nm is less than or equal to 2%. Furthermore, the intermediate layer 13 can also absorb only UV rays with a wavelength less than or equal to 400 nm, and the transmittance of UV rays with a wavelength less than or equal to 400 nm is less than or equal to 2%.

[0134] In this application scenario, the material of the intermediate layer 13 can be polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA).

[0135] It is understandable that in the sandwich structure of traditional car window glass, although the middle layer has a certain UV protection ability, it can generally only absorb ultraviolet rays with a wavelength less than 380nm, and has poorer absorption ability for long-wave ultraviolet rays with stronger penetrating ability in the wavelength range of 380nm to 400nm.

[0136] Therefore, in this application scenario, by enabling the intermediate layer 13 to block ultraviolet rays with a wavelength lower than 410 nm and having a transmittance of less than or equal to 2% for ultraviolet rays with a wavelength less than or equal to 410 nm, the vehicle window glass 100 can block long-wave ultraviolet rays with stronger penetrating ability in the wavelength range of 380 nm to 400 nm, thereby expanding the wavelength range of ultraviolet rays that the vehicle window glass 100 can absorb, enhancing the ultraviolet absorption capacity of the intermediate layer 13, and further enhancing the ultraviolet absorption capacity of the vehicle window glass 100, so that the sunlight that passes through the vehicle window glass 100 and irradiates the optical sensor 220 can filter out ultraviolet rays through the intermediate layer 13 in the vehicle window glass 100, thereby greatly reducing the transmittance of ultraviolet rays on the vehicle window glass 100 and the probability of irradiating the optical sensor 220.

[0137] In this application scenario, the colored layer 20 can be connected between the outer glass plate 12 and the intermediate layer 13 (eg Figure 2 As shown). And / or, the colored layer 20 is connected between the intermediate layer 13 and the inner glass plate 14. The colored layer 20 is a single-layer structure and is used to adjust the color of the vehicle window glass 100 and block near infrared rays.

[0138] In the second possible application scenario, see Figure 3 , Figure 3 It is along Figure 1 The second schematic cross-sectional view of the partial structure of the vehicle window glass 100 according to the first embodiment is obtained by cutting along the cutting line AA.

[0139] In this application scenario, the same contents as those in the first application scenario will not be repeated. The difference from the first application scenario is that the intermediate layer 13 is not an enhanced ultraviolet absorption layer. The vehicle window glass 100 may include an enhanced ultraviolet absorption layer 30. The enhanced ultraviolet absorption layer 30 is connected between the outer glass plate 12 and the inner glass plate 14, and the projection of the enhanced ultraviolet absorption layer 30 on the glass body 10 along the thickness direction of the glass body 10 at least covers the signal transmission area 11, so that the sunlight that passes through the vehicle window glass 100 and irradiates the optical sensor 220 can be filtered out of ultraviolet rays by the enhanced ultraviolet absorption layer 30 in the vehicle window glass 100. That is, an independent enhanced ultraviolet absorption layer is additionally provided in this application scenario. However, it should be understood that in this application scenario, the intermediate layer 13 can still be a layer structure with a certain ultraviolet absorption ability. Optionally, the enhanced ultraviolet absorption layer 30 can be connected between the intermediate layer 13 and the inner glass plate 14. And / or, the enhanced ultraviolet absorption layer 30 can also be connected between the outer glass plate 12 and the intermediate layer 13. For example, as Figure 3 As shown, the enhanced UV absorbing layer 30 is connected between the interlayer 13 and the inner glass pane 14 .

[0140] The enhanced ultraviolet absorption layer 30 can absorb ultraviolet rays with a wavelength of less than or equal to 410 nm, and has a transmittance of less than or equal to 2% for ultraviolet rays with a wavelength of less than or equal to 410 nm. Furthermore, the enhanced ultraviolet absorption layer 30 can also absorb only ultraviolet rays with a wavelength of less than or equal to 400 nm, and have a transmittance of less than or equal to 2% for ultraviolet rays with a wavelength of less than or equal to 400 nm.

[0141] In this application scenario, the material of the enhanced ultraviolet absorption layer 30 can be polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA).

[0142] It is understandable that this application scenario can also expand the wavelength range of ultraviolet rays that the vehicle window glass 100 can absorb, thereby enhancing the anti-ultraviolet ability of the vehicle window glass 100.

[0143] In the third possible application scenario, please refer to Figure 4 、 Figure 5 and Figure 6 , Figure 4 It is along Figure 1 The third schematic cross-sectional view of the partial structure of the vehicle window glass 100 of the first embodiment obtained by cutting along the cutting line AA is shown. Figure 5 It is along Figure 1 The fourth cross-sectional schematic diagram of the partial structure of the vehicle window glass 100 of the first embodiment obtained by cutting along the cutting line AA is shown. Figure 6 It is along Figure 1 The fifth schematic cross-sectional view of the partial structure of the vehicle window glass 100 according to the first embodiment is obtained by cutting along the cutting line AA.

[0144] In this application scenario, the details common to the second application scenario are omitted. However, the difference from the second application scenario is that the enhanced UV absorption layer 30 is attached to the side of the inner glass plate 14 facing away from the intermediate layer 13. The projection of the enhanced UV absorption layer 30 on the glass body 10 along the thickness direction of the glass body 10 at least covers the signal transmission area 11, ensuring that any sunlight that passes through the window glass 100 and strikes the optical sensor 220 is filtered out of UV rays by the enhanced UV absorption layer 30 within the window glass 100.

[0145] For example, Figure 4 As shown, the enhanced ultraviolet absorbing layer 30 is connected to the surface of the inner glass plate 14 away from the intermediate layer 13. The projection of the enhanced ultraviolet absorbing layer 30 on the glass body 10 along the thickness direction of the glass body 10 covers the entire surface of the inner glass plate 14 away from the intermediate layer 13. Alternatively, as shown in FIG. Figure 5As shown, the enhanced ultraviolet absorbing layer 30 is connected to the surface of the inner glass plate 14 away from the intermediate layer 13. The projection of the enhanced ultraviolet absorbing layer 30 on the glass body 10 along the thickness direction of the glass body 10 just covers the signal transmission area 11. Alternatively, as Figure 6 As shown, the enhanced UV absorbing layer 30 is connected to the side of the inner glass pane 14 facing away from the interlayer 13, but is not directly connected to the surface of the inner glass pane 14 facing away from the interlayer 13. Other layer structures may be provided between the enhanced UV absorbing layer 30 and the inner glass pane 14.

[0146] Please continue reading Figure 2-Figure 6 In this embodiment, the vehicle window glass 100 may further include an anti-reflection layer 40. The anti-reflection layer 40 is attached to the side of the inner glass panel 14 facing away from the intermediate layer 13. For example, the anti-reflection layer 40 may be applied to the side of the inner glass panel 14 facing away from the intermediate layer 13 using a film, patch, or coating. The projection of the anti-reflection layer 40 on the glass body 10 along the thickness direction of the glass body 10 at least covers the signal transmission area 11. The anti-reflection layer 40 is used to reduce near-infrared reflection. Since the wavelength band of the optical sensor 220 signal in this embodiment is close to the near-infrared band, the anti-reflection layer 40 also serves to reduce reflection of the optical sensor 220 signal.

[0147] It is understood that when the optical sensor 220 signal is transmitted from the interior of the vehicle 200 to the exterior of the vehicle 200, the optical sensor 220 signal is reflected when passing through the surface of the inner glass panel 14 facing away from the intermediate layer 13, resulting in a decrease in the transmittance of the optical sensor 220 signal through the vehicle window glass 100. In this embodiment, by providing an anti-reflection layer 40 on the surface of the inner glass panel 14 facing away from the intermediate layer 13, it is possible to reduce the reflection of the optical sensor 220 signal when passing through the surface of the inner glass panel 14 facing away from the intermediate layer 13, thereby increasing the transmittance of the optical sensor 220 signal through the vehicle window glass 100 and enabling effective detection by the optical sensor 220.

[0148] Furthermore, the anti-reflection layer 40 can also be used to adjust the color of the vehicle window glass 100 .

[0149] Understandably, see Figure 2When the colored layer 20 is a single-layer structure and its projection on the glass body 10 along the thickness direction of the glass body 10 is offset from the signal-transmitting area 11, the signal-transmitting area 11 of the vehicle window glass 100 is not provided with the colored layer 20, making color adjustment difficult. Therefore, by covering the signal-transmitting area 11 with the anti-reflection layer 40 and adjusting the color of the vehicle window glass 100, the color gap in the signal-transmitting area 11 of the vehicle window glass 100 can be filled, allowing the color of the entire area of the vehicle window glass 100 to be adjusted. This helps reduce the color difference between high-transmittance glass combinations and traditional glass combinations, and improves the overall aesthetics of the vehicle 200.

[0150] For example, Figure 2 As shown, when the intermediate layer 13 is an enhanced UV absorbing layer, the anti-reflection layer 40 is connected to the surface of the inner glass plate 14 facing away from the intermediate layer 13 .

[0151] Or, as Figure 3 As shown, when the intermediate layer 13 is a non-reinforced UV absorbing layer and an independent enhanced UV absorbing layer 30 is provided on the vehicle window glass 100 , the enhanced UV absorbing layer 30 is connected between the intermediate layer 13 and the inner glass plate 14 , and the anti-reflection layer 40 is connected to the surface of the inner glass plate 14 facing away from the intermediate layer 13 .

[0152] Or, as Figure 4 and Figure 5 As shown, when the interlayer 13 is a non-reinforced UV-absorbing layer and a separate reinforced UV-absorbing layer 30 is provided on the vehicle window glass 100, the reinforced UV-absorbing layer 30 is connected to the surface of the inner glass pane 14 facing away from the interlayer 13. The anti-reflection layer 40 is connected to the surface of the reinforced UV-absorbing layer 30 facing away from the inner glass pane 14.

[0153] Or, as Figure 6 As shown, when the intermediate layer 13 is a non-reinforced UV-absorbing layer and an independent enhanced UV-absorbing layer 30 is provided on the vehicle window glass 100 , the anti-reflection layer 40 is connected to the surface of the inner glass plate 14 facing away from the intermediate layer 13 , and the enhanced UV-absorbing layer 30 is connected to the surface of the anti-reflection layer 40 facing away from the inner glass plate 14 .

[0154] In this embodiment, at the vehicle installation angle (i.e., when the window glass 100 is mounted on the vehicle body sheet metal 210), the transmittance of the optical sensor 220 signal within the wavelength range of 800 nm to 1600 nm (inclusive) through the window glass 100 is greater than or equal to 80%. Furthermore, since all optical sensor 220 signals pass through the signal transmission zone 11 of the window glass 100, at the vehicle installation angle, the transmittance of the optical sensor 220 signal within the wavelength range of 800 nm to 1600 nm (inclusive) through the signal transmission zone 11 of the window glass 100 is greater than or equal to 80%. For example, at the vehicle installation angle, the transmittance of the optical sensor 220 signal with a wavelength of 905 nm within the signal transmission zone 11 of the vehicle window glass 100 is greater than or equal to 80%. Alternatively, at the vehicle installation angle, the transmittance of the optical sensor 220 signal with a wavelength of 1550 nm within the signal transmission zone 11 of the vehicle window glass 100 is greater than or equal to 80%. Furthermore, because the wavelength band of near-infrared light is similar to that of the optical sensor 220 signal, the transmittance of near-infrared light with a wavelength between 800 nm and 1600 nm (inclusive) within the signal transmission zone 11 of the vehicle window glass 100 is greater than or equal to 80%.

[0155] In this embodiment, preferably, at the vehicle installation angle, the transmittance of the optical sensor 220 signal within the signal transmission zone 11 of the vehicle window glass 100 within a wavelength range of 800 nm to 1600 nm (inclusive) is greater than or equal to 85%. More preferably, at the vehicle installation angle, the transmittance of the optical sensor 220 signal within the signal transmission zone 11 of the vehicle window glass 100 within a wavelength range of 800 nm to 1600 nm (inclusive) is greater than or equal to 90%. Even more preferably, at the vehicle installation angle, the transmittance of the optical sensor 220 signal within the signal transmission zone 11 of the vehicle window glass 100 within a wavelength range of 800 nm to 1600 nm (inclusive) is greater than or equal to 95%.

[0156] It should be noted that the mounting angle is the angle between the vehicle window glass 100 and a horizontal plane. The horizontal plane is a plane parallel to the length and width of the vehicle 200. When the vehicle window glass 100 serves as the front windshield of the vehicle 200, the mounting angle is typically 20°-40°, such as 20°, 25°, 30°, 35°, or 40°. The optical sensor 220 is typically mounted horizontally (i.e., the optical sensor 220 is typically positioned parallel to the horizontal plane described above). The incident angle of the optical sensor 220 signal on the vehicle window glass 100 is generally 50°-70°, such as 50°, 55°, 60°, 65°, or 70°. In other words, the transmittance of the signal-transmitting area 11 of the vehicle window glass 100 in this embodiment is greater than or equal to 80% for near-infrared light with a wavelength in the range of 800 nm to 1600 nm (inclusive) incident at an angle of 50°-70°.

[0157] In some other embodiments, when at the vehicle installation angle (i.e., the vehicle window glass 100 is installed on the vehicle body sheet metal 210), when the transmittance of the optical sensor 220 signal with a wavelength in the range of 800nm-1600nm (including the endpoint values 800nm and 1600nm) on the vehicle window glass 100 is greater than or equal to 80%, the anti-reflection layer 40 may not be provided.

[0158] It is understood that the reflectivity of the optical sensor 220 signal passing through the window glass 100 varies at different angles. The greater the tilt angle of the window glass 100, the greater the reflectivity of the optical sensor 220 signal passing through the window glass 100. When the optical sensor 220 signal passes perpendicularly through the window glass 100 (i.e., the optical sensor 220 signal passes through the window glass 100 along the thickness direction of the window glass 100), the reflectivity of the optical sensor 220 signal passing through the window glass 100 is minimal, and the transmittance is maximized. In contrast, after the window glass 100 is mounted on the vehicle body sheet metal 210, the tilt angle of the window glass 100 increases, and the reflectivity of the optical sensor 220 signal passing through the window glass 100 increases, resulting in a decrease in the transmittance of the optical sensor 220 signal. Therefore, if the transmittance of the optical sensor 220 signal on the vehicle window glass 100 can reach or exceed 80% at the vehicle installation angle, this means that even without the help of the anti-reflection layer 40, the transmittance of the optical sensor 220 signal of not less than 80% can enable the optical sensor 220 to perform effective detection.

[0159] Second embodiment:

[0160] Please refer to Figure 7 and Figure 8 , Figure 7 It is along Figure 1The first cross-sectional schematic diagram of the partial structure of the vehicle window glass 100 of the second embodiment obtained by cutting along the cutting line AA is shown. Figure 8 It is along Figure 1 The section line AA shown is a second schematic cross-sectional view of a partial structure of the vehicle window glass 100 of the second embodiment.

[0161] In this embodiment, the details common to the first embodiment are omitted. Unlike the first embodiment, this embodiment does not include a separate, enhanced UV absorption layer 30, nor does it include the intermediate layer 13 as an enhanced UV absorption layer. Furthermore, in this embodiment, a colored layer 20 is attached between the outer glass panel 12 and the inner glass panel 14. Alternatively, the colored layer 20 is attached to the side of the inner glass panel 14 facing away from the intermediate layer 13. The colored layer 20 is used to adjust the color of the vehicle window glass 100 and block UV rays. The colored layer 20 is a single-layer structure. The following description of the vehicle window glass 100 applies to the first embodiment above, unless otherwise specified.

[0162] It is understood that by adjusting the colored layer 20, and thus adjusting the Lab value of the reflected color of the vehicle window glass 100, the color of the vehicle window glass 100 can be adjusted, thereby reducing the color difference between the high-transmittance glass combination and the traditional glass combination in the same vehicle 200 (or vehicles 200 of the same series but with different configurations), thereby improving the aesthetics of the vehicle 200. Furthermore, the colored layer 20 of this embodiment can be used to block ultraviolet rays, so that any sunlight that passes through the vehicle window glass 100 and illuminates the optical sensor 220 can be filtered out of the ultraviolet rays by the colored layer 20 within the vehicle window glass 100, thereby greatly reducing the probability of ultraviolet rays irradiating the optical sensor 220 and damaging it.

[0163] In this embodiment, the colored layer 20 can absorb ultraviolet rays with a wavelength less than or equal to 410 nm, and has a transmittance of less than or equal to 2% for ultraviolet rays with a wavelength less than or equal to 410 nm. Furthermore, the colored layer 20 can also absorb only ultraviolet rays with a wavelength less than or equal to 400 nm, and have a transmittance of less than or equal to 2% for ultraviolet rays with a wavelength less than or equal to 400 nm. For example, the material of the colored layer 20 can be polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA).

[0164] In one possible implementation, see Figure 7The colored layer 20 is a single-layer structure. It is connected between the intermediate layer 13 and the inner glass panel 14 and is used to adjust the color of the vehicle window glass 100 and block ultraviolet rays. It is understood that the colored layer 20 can also be connected between the outer glass panel 12 and the intermediate layer 13.

[0165] In another possible implementation, see Figure 8 The colored layer 20 is a single-layer structure. The colored layer 20 is connected to the surface of the inner glass plate 14 away from the intermediate layer 13 and is used to adjust the color of the vehicle window glass 100 and block ultraviolet rays.

[0166] In this embodiment, since the outer glass plate 12 and / or the inner glass plate 14 have a high near-infrared transmittance, in order to avoid heat accumulation caused by near-infrared radiation, it is necessary to enhance the near-infrared protection capability of the vehicle window glass 100. Specifically, the vehicle window glass 100 may include a near-infrared reflective layer 50. The near-infrared reflective layer 50 is connected between the outer glass plate 12 and the intermediate layer 13. And / or, the near-infrared reflective layer 50 is connected between the intermediate layer 13 and the inner glass plate 14. And the projection of the near-infrared reflective layer 50 on the glass body 10 along the thickness direction of the glass body 10 is staggered with the signal transmission area 11. Exemplarily, the near-infrared reflective layer 50 can be a near-infrared reflective (IRR) coating layer. The near-infrared transmittance of the near-infrared reflective layer 50 is less than or equal to 20%. The total solar transmittance (TTS) of the area covered by the near-infrared reflective layer 50 in the vehicle window glass 100 is less than or equal to 55%. As Figure 7 and Figure 8 As shown, the near infrared reflecting layer 50 in this embodiment is connected between the outer glass plate 12 and the intermediate layer 13 .

[0167] It should be noted that, in the following embodiments, unless there is any conflict, all of the following are in compliance with the present invention:

[0168] If the colored layer 20 can block near-infrared rays but not ultraviolet rays, then in this embodiment, no other layer for blocking near-infrared rays is required, but another layer for blocking ultraviolet rays is required (such as an independent enhanced ultraviolet absorption layer 30 or configuring the intermediate layer 13 as an enhanced ultraviolet absorption layer). The specific structure and characteristics of the colored layer 20 for blocking near-infrared rays can refer to the characteristics of the colored layer 20 for blocking near-infrared rays in the first embodiment, and will not be repeated here.

[0169] If the colored layer 20 can block ultraviolet rays but not near-infrared rays, then in this embodiment, no other layer for blocking ultraviolet rays is required, but a layer for blocking near-infrared rays (such as the near-infrared reflective layer 50) is required. The specific features of the colored layer 20 for blocking ultraviolet rays can refer to the features of the intermediate layer 13 for blocking ultraviolet rays or the enhanced ultraviolet absorption layer 30 for blocking ultraviolet rays in the first embodiment, and will not be further described below.

[0170] If the colored layer 20 can block both near-infrared and ultraviolet rays, then in this embodiment, no additional layers for blocking near-infrared or ultraviolet rays are required. The specific features of the colored layer 20 for blocking near-infrared rays can refer to the features of the colored layer 20 for blocking near-infrared rays in the first embodiment, and the specific features of the colored layer 20 for blocking ultraviolet rays can refer to the features of the intermediate layer 13 for blocking ultraviolet rays or the enhanced ultraviolet absorption layer 30 in the first embodiment, and will not be further described below.

[0171] Third embodiment:

[0172] See also Figure 9 , Figure 9 It is along Figure 1 The section line AA shown is a schematic cross-sectional view of a partial structure of the vehicle window glass 100 according to the third embodiment.

[0173] In this embodiment, the details common to the second embodiment are omitted. Unlike the second embodiment, the entire colored layer 20 can form part of the glass body 10. Specifically, the entire colored layer 20 forms the intermediate layer 13. The colored layer 20 is a single-layer structure. The colored layer 20 has adhesive properties, allowing it to bond the outer glass sheet 12 and the inner glass sheet 14 together. The colored layer 20 is used to adjust the color of the vehicle window glass 100 and block ultraviolet rays.

[0174] Fourth embodiment:

[0175] See also Figure 10 , Figure 10 It is along Figure 1 The section line AA shown is a schematic cross-sectional view of a partial structure of the vehicle window glass 100 according to the fourth embodiment.

[0176] The colored layer 20 in this embodiment is used to block near-infrared rays. Details similar to those in the first embodiment will not be repeated. Unlike the first embodiment, the colored layer 20 comprises at least two layers. Specifically, the colored layer 20 comprises a two-layer structure. The colored layer 20 includes a first sublayer 21 and a second sublayer 22. The first sublayer 21 is used only to block near-infrared rays and is not used to adjust the color of the vehicle window glass 100.
