To achieve higher detection accuracy, LiDAR is typically mounted on the exterior of the vehicle, such as integrated into the roof, bumper, or headlights. However, integrating LiDAR into the roof can lead to dust or dirt buildup, potentially disabling intelligent driving, requiring regular maintenance, and affecting the vehicle's appearance. Integrating it into the bumper results in poor visibility, susceptibility to contamination, and increased risk of scratches. Integrating it into headlights presents challenges such as easy contamination and high requirements for high-temperature reliability. Summary of the Invention

[0053] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0054] It should be noted that, for ease of explanation, the same reference numerals denote the same components in the embodiments of this application, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0055] To improve the safety of intelligent driving, related technologies employ multiple sensors (including cameras and LiDAR) to simulate human vision and acquire environmental information about the vehicle's surroundings. To achieve higher detection accuracy, LiDAR is typically mounted on the exterior of the vehicle, such as integrated into the roof, bumper, or headlights. However, integrating LiDAR into the roof can lead to dust or dirt buildup, potentially disabling intelligent driving, requiring regular maintenance, and affecting the vehicle's appearance. Integrating it into the bumper results in poor visibility, susceptibility to contamination, and increased risk of scratches. Integrating it into headlights presents challenges such as easy contamination and high requirements for high-temperature reliability.

[0056] Please see Figures 1 to 3 This application provides a vehicle window assembly 100, which includes a window glass 10a, a sensor assembly 50, a heating assembly 30, and a mounting assembly 20. The window glass 10a includes a glass substrate 10, which has a first window area 101 and a second window area 102, with an overlap between the first window area 101 and the second window area 102. The sensor assembly 50 is mounted on the mounting assembly 20, and both the sensor assembly 50 and the mounting assembly 20 are located on one side of the window glass 10a. The sensor assembly 50 includes a first sensor 51 and a second sensor 52, both of which are mounted on the mounting assembly 20. The heating assembly 30 is located on the window glass 10a and / or the mounting assembly 20, and is used to heat the first window area 101 and the second window area 102.

[0057] The window assembly 100 of this application embodiment can be applied to vehicles, for example, as, but not limited to, the windshield of a vehicle. The vehicle of this application can be, but is not limited to, automobiles, cars, buses, trucks, trains, and other means of transportation.

[0058] It should be noted that when the window assembly 100 is installed in the vehicle, the mounting component 20 is located inside the vehicle. When the window assembly 100 is installed in the vehicle, the mounting component 20 is positioned near the top of the vehicle. Understandably, when the window assembly 100 is installed in the vehicle, the first sensor 51 and the second sensor 52 are located inside the vehicle.

[0059] Optionally, the first sensor 51 may include at least one of lidar and a camera. The first sensor 51 is used to sense environmental information of the vehicle, such as obstacle information, to assist the vehicle in intelligent driving.

[0060] Optionally, the second sensor 52 may include at least one of LiDAR and a camera. The second sensor 52 is used to sense environmental information of the vehicle, such as obstacle information, to assist the vehicle in intelligent driving.

[0061] Optionally, the number of first sensors 51 can be one or more, and when there are multiple first sensors 51, the multiple first sensors 51 are arranged at intervals. For example, the number of first sensors 51 can be one, two, three, four, etc.

[0062] Optionally, the number of second sensors 52 can be one or more, and when there are multiple second sensors 52, the multiple second sensors 52 are arranged at intervals. For example, the number of second sensors 52 can be one, two, three, four, etc.

[0063] In some embodiments, the first sensor 51 is a lidar, and the second sensor 52 is a camera. In other embodiments, the first sensor 51 is a camera, and the second sensor 52 is a lidar. In the following embodiments of this application, unless otherwise specified, the first sensor 51 is a lidar and the second sensor 52 is a camera, which should not be construed as a limitation on the window assembly 100 of the embodiments of this application.

[0064] It should be noted that the first window region 101 is the transmission region of the optical signal of the first sensor 51 on the glass substrate 10. The second window region 102 is the transmission region of the optical signal of the second sensor 52 on the glass substrate 10.

[0065] The window assembly 100 of this application embodiment includes a window glass 10a, a sensor assembly 50, a heating assembly 30, and a mounting assembly 20. The sensor assembly 50 is mounted on the mounting assembly 20, and both the sensor assembly 50 and the mounting assembly 20 are located on one side of the window glass 10a. The sensor assembly 50 includes a first sensor 51 and a second sensor 52, and both the first sensor 51 and the second sensor 52 are mounted on the mounting assembly 20. When the window assembly 100 is applied to a vehicle, the first sensor 51 and the second sensor 52 are located inside the vehicle. The glass substrate 10 can effectively block dust and other dirt, and the working environment inside the vehicle is better, thereby giving the first sensor 51 and the second sensor 52 better dustproof and dirt-proof functions. When the glass substrate 10 is dirty, it can be cleaned using the vehicle's cleaning device (such as a windshield wiper cleaning system), without the need for an additional cleaning system for the first sensor 51 and the second sensor 52. Furthermore, when the window assembly 100 is applied to a vehicle, the mounting component 20 and sensor component 50 are located inside the vehicle, resulting in a more aesthetically pleasing overall vehicle design and lower wind resistance. Moreover, by incorporating the heating component 30, the glass substrate 10 and sensor component 50 can be defogging and defrosted, preventing fogging or frost buildup on these components, which could affect the vehicle's intelligent driving functions.

[0066] In some embodiments, the window assembly 100 further includes a bracket 21, which is fixedly connected to the inner surface 103 of the glass substrate 10. The first sensor 51 and the second sensor 52 are both disposed in the bracket 21 and are spaced apart from the glass substrate 10.

[0067] It should be noted that the inner surface 103 refers to the surface of the glass substrate 10 facing the interior of the vehicle when the window assembly 100 is applied to a vehicle.

[0068] Optionally, the support 21 is bonded to the surface of the glass substrate 10 by an adhesive.

[0069] In this embodiment, both the first sensor 51 and the second sensor 52 are housed within the bracket 21, which better protects the first sensor 51 and the second sensor 52, giving them better dustproof and anti-fouling functions.

[0070] Please see Figure 4 In some embodiments, the heating assembly 30 includes a first heating element 31, which is disposed on the vehicle window glass 10a and at least covers the first window area 101 and the second window area 102. The first heating element 31 is used to heat the first window area 101 and the second window area 102.

[0071] Understandably, the first heating element 31 is conductive. By applying an electrical signal such as voltage or current, the first heating element 31 heats up, thereby defogging and defrosting the first window area 101 and the second window area 102. This prevents fogging or frost from forming on the glass substrate 10 at the positions corresponding to the first window area 101 and the second window area 102, which would affect the function of the sensor assembly 50 and consequently affect the use of the vehicle's intelligent driving function, reducing the reliability of intelligent driving.

[0072] In this embodiment, by providing a first heating element 31 in the first window area 101 and the second window area 102, when the first window area 101 and the second window area 102 fog or frost, it is only necessary to use the first heating element 31 to heat the first window area 101 and the second window area 102 to achieve defogging and defrosting of the glass substrate 10, thus avoiding fogging or frosting of the first window area 101 and the second window area 102, which would affect the detection accuracy of the sensor assembly 50 and thus affect the use of the vehicle's intelligent driving function.

[0073] In some embodiments, the first heating element 31 is a transparent heating film.

[0074] Alternatively, the transparent heating film can transmit visible light and infrared light.

[0075] Alternatively, the transparent heating film can be formed through processes such as coating, printing, etc.

[0076] Optionally, the transparent heating film can be made of, but is not limited to, carbon nanotubes.

[0077] Understandably, the transparent heating film covers at least the entire first window area 101 and the second window area 102. In other embodiments, the transparent heating film may also cover areas of the glass substrate 10 other than the first window area 101 and the second window area 102.

[0078] In this embodiment, a transparent heating film is used as the first heating element 31. The transparent heating film can transmit visible light and infrared light, so that while defrosting and defogging the glass substrate 10 is achieved, the transmission of optical signals of the first sensor 51 and the second sensor 52 will not be affected.

[0079] Please see Figure 5In some embodiments, the heating assembly 30 includes a first heating element 31 and a second heating element 32. The first heating element 31 is disposed on the vehicle window glass 10a, and the second heating element 32 is disposed on the mounting assembly 20. The first heating element 31 avoids the first window area 101 and is at least partially disposed on the second window area 102. The first heating element 31 at least corresponds to heating the non-overlapping area of ​​the second window area 102. The second heating element 32 avoids the transmission path of the optical signals of the first sensor 51 and the second sensor 52 and is at least partially spaced from the vehicle window glass 10a. The second heating element 32 at least corresponds to heating the first window area 101.

[0080] It should be noted that both the first heating element 31 and the second heating element 32 are conductive. The first heating element 31 and the second heating element 32 can be heated by applying electrical signals such as voltage or current, so as to achieve the effect of defogging and defrosting, so as to avoid fogging or frost at the first window area 101 and the second window area 102 of the glass substrate 10, which would affect the function of the first sensor 51 and the second sensor 52, and thus affect the use of the vehicle's intelligent driving function and reduce the reliability of intelligent driving.

[0081] In this embodiment, by providing a first heating element 31 and a second heating element 32, the first heating element 31 can heat the first window area 101 of the glass substrate 10 to remove fog; the second heating element 32 can remove fog from the second window area 102 of the glass substrate 10 through thermal radiation. This better prevents fogging or frost formation in the first and second window areas 101 and 102 of the glass substrate 10 from affecting the function of the sensor assembly 50, thereby affecting the use of the vehicle's intelligent driving function and reducing the reliability of intelligent driving. Furthermore, the second heating element 32 avoids the transmission paths of the optical signals of the first sensor 51 and the second sensor 52, thus not affecting the signal transmission of the first sensor 51 and the second sensor 52.

[0082] In other embodiments, the heating assembly 30 includes only a second heating element 32, which is disposed on the mounting assembly 20. The second heating element 32 avoids the transmission paths of the optical signals of the first sensor 51 and the second sensor 52 and is at least partially spaced from the window glass 10a. The second heating element 32 is disposed to heat at least the first window area 101 and the second window area 102. In this embodiment, by providing the second heating element 32 on the mounting assembly 20, the first window area 101 and the second window area 102 of the glass substrate 10 are heated by the second heating element 32, thereby achieving defogging of the first window area 101 and the second window area 102 of the glass substrate 10 and improving the reliability of the vehicle's intelligent driving function.

[0083] In some embodiments, the second heating element 32 heats the first window area 101 by thermal radiation, and the second heating element 32 includes a heating film.

[0084] Optionally, the heating film may be, but is not limited to, a transparent heating film.

[0085] In this embodiment, the first window area 101 is heated by thermal radiation to achieve defogging of the first window area 101 of the glass substrate 10. This allows for more options for the second heating element 32, and there is no need to set up defogging or defrosting heating elements at the position of the glass that basically corresponds to the first window area 101. This avoids the influence of the heating element on the transmission of the optical signal of the first sensor 51 after the first window area 101 is set up.

[0086] In some embodiments, when the second sensor 52 is a camera, the first heating element 31 is a silver paste wire, and the wire diameter of the first heating element 31 is 0.3mm-0.6mm.

[0087] In the embodiments of this application, when the numerical range a to b is involved, unless otherwise specified, the numerical value can be any value between a and b, including the endpoint value a and the endpoint value b.

[0088] Specifically, the wire diameter of the first heating element 31 can be, but is not limited to, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, etc. If the wire diameter of the first heating element 31 is too small, it increases the processing difficulty of the first heating element 31; if the wire diameter of the first heating element 31 is too large, it may be visible to the naked eye and affect the appearance of the window assembly 100.

[0089] In this embodiment, by setting a silver paste line as the first heating element 31 in the area of ​​the second window corresponding to the window glass 10a, the second window area 102 can be heated and defogged more effectively, thereby improving the reliability of the vehicle's intelligent driving function.

[0090] In some embodiments, when the second sensor 52 is a lidar, the first heating element 31 is an enameled wire with a wire diameter of 0.05mm-0.2mm.

[0091] Specifically, the wire diameter of the first heating element 31 can be, but is not limited to, 0.05mm, 0.08mm, 0.1mm, 0.12mm, 0.14mm, 0.16mm, 0.18mm, 0.2mm, etc. If the wire diameter of the first heating element 31 is too small, it increases the processing difficulty of the first heating element 31; if the wire diameter of the first heating element 31 is too large, it may be visible to the naked eye and affect the appearance of the window assembly 100.

[0092] In this embodiment, by setting an enameled wire as the first heating element 31 in the second window area 102 corresponding to the window glass 10a, the second window area 102 can be heated and defogged more effectively, thereby improving the reliability of the vehicle's intelligent driving function.

[0093] In some embodiments, the transmittance of the first window region 101 for near-infrared light with a wavelength range of 800nm-1600nm (inclusive of the endpoints 800nm ​​and 1600nm) is greater than or equal to 80%. Specifically, the transmittance of the first window region 101 for near-infrared light with a wavelength range of 800nm-1600nm can be, but is not limited to, greater than or equal to 80%, greater than or equal to 82%, greater than or equal to 85%, greater than or equal to 88%, greater than or equal to 90%, greater than or equal to 93%, greater than or equal to 95%, etc. In this embodiment, if the transmittance of the first window region 101 of the glass substrate 10 for near-infrared light with a wavelength range of 800nm-1600nm is too low, when the sensor assembly 50 installed in the mounting assembly 20 includes a lidar, it will affect the transmission and reception of lidar signals, thereby reducing the detection accuracy and precision of the lidar.

[0094] Specifically, the first window region 101 has a transmittance of greater than or equal to 80% for near-infrared light with a wavelength range of 840nm-940nm (inclusive of the endpoints 840nm and 940nm). For example, the first window region 101 has a transmittance of greater than or equal to 80% for near-infrared light with a wavelength of 905nm.

[0095] Specifically, the first window region 101 has a transmittance of greater than or equal to 80% for near-infrared light with a wavelength range of 1500nm-1600nm (inclusive of the endpoints 1500nm and 1600nm). For example, the first window region 101 has a transmittance of greater than or equal to 80% for near-infrared light with a wavelength of 1550nm.

[0096] In some embodiments, the transmittance of the second window region 102 for near-infrared light with a wavelength range of 800nm-1600nm is greater than or equal to 80%. Specifically, the transmittance of the second window region 102 for near-infrared light with a wavelength range of 800nm-1600nm can be, but is not limited to, greater than or equal to 80%, greater than or equal to 82%, greater than or equal to 85%, greater than or equal to 88%, greater than or equal to 90%, greater than or equal to 93%, greater than or equal to 95%, etc. In this embodiment, if the transmittance of the second window region 102 of the glass substrate 10 for near-infrared light with a wavelength range of 800nm-1600nm is too low, then when the sensor assembly 50 installed in the mounting assembly 20 includes a lidar, it will affect the transmission and reception of lidar signals, thereby reducing the detection accuracy and precision of the lidar.

[0097] Specifically, the second window region 102 has a transmittance of greater than or equal to 80% for near-infrared light with a wavelength range of 840nm-940nm (inclusive of the endpoints 840nm and 940nm). For example, the second window region 102 has a transmittance of greater than or equal to 80% for near-infrared light with a wavelength of 905nm.

[0098] Specifically, the second window region 102 has a transmittance of greater than or equal to 80% for near-infrared light with a wavelength range of 1500nm-1600nm (inclusive of the endpoints 1500nm and 1600nm). For example, the second window region 102 has a transmittance of greater than or equal to 80% for near-infrared light with a wavelength of 1550nm.

[0099] Optionally, the incident angle of the optical signals of the first sensor 51 and the second sensor 52 on the window glass 10a is approximately 50°-70°, such as 50°, 55°, 60°, 65°, 70°, etc.

[0100] Optionally, the transmittance of the first window region 101 and the second window region 102 for near-infrared light with an incident angle of 50°-70° and a wavelength range of 800nm-1600nm is greater than or equal to 80%. Specifically, the transmittance of the first window region 101 and the second window region 102 for near-infrared light with an incident angle of 50°-70° and a wavelength range of 800nm-1600nm can be, but is not limited to, greater than or equal to 80%, greater than or equal to 82%, greater than or equal to 85%, greater than or equal to 88%, greater than or equal to 90%, greater than or equal to 93%, greater than or equal to 95%, etc. The operating wavelength of the lidar is mainly at least one of 905nm and 1550nm, which ensures that the lidar signal can pass well through the first window region 101 and the second window region 102 of the glass substrate 10, so that the lidar has higher detection accuracy and precision.

[0101] Specifically, the first window region 101 and the second window region 102 have a transmittance of greater than or equal to 80% for near-infrared light with an incident angle of 50°-70° and a wavelength range of 840nm-940nm (inclusive of the endpoints 840nm and 940nm). For example, the first window region 101 and the second window region 102 have a transmittance of greater than or equal to 80% for near-infrared light with an incident angle of 50°-70° and a wavelength of 905nm.

[0102] Specifically, the first window region 101 and the second window region 102 have a transmittance of greater than or equal to 80% for near-infrared light with an incident angle of 50°-70° and a wavelength range of 1500nm-1600nm (inclusive of the endpoints 1500nm and 1600nm). For example, the first window region 101 and the second window region 102 have a transmittance of greater than or equal to 80% for near-infrared light with an incident angle of 50°-70° and a wavelength of 1550nm.

[0103] Optionally, the transmittance of the first window region 101 and the second window region 102 for near-infrared light with an incident angle of 50°-70° and a wavelength range of 800nm-1600nm is greater than or equal to 85%. The operating wavelength of the lidar is mainly at least one of 905nm and 1550nm, which ensures that the lidar signal can pass well through the positions of the first window region 101 and the second window region 102 of the glass substrate 10, so that the lidar has higher detection accuracy and precision.

[0104] Optionally, the transmittance of the first window region 101 and the second window region 102 for near-infrared light with an incident angle of 50°-70° and a wavelength range of 800nm-1600nm is greater than or equal to 90%. The operating wavelength of the lidar is mainly at least one of 905nm and 1550nm, which ensures that the lidar signal can pass well through the positions of the first window region 101 and the second window region 102 of the glass substrate 10, thereby giving the lidar higher detection accuracy and precision.

[0105] Please see Figure 6 and Figure 7 In some embodiments, the glass substrate 10 includes a first glass layer 11, an adhesive layer 13, and a second glass layer 14. The first glass layer 11 has a first surface 111 and a second surface 112 disposed opposite to each other, and the second glass layer 14 has a third surface 141 and a fourth surface 142 disposed opposite to each other. The adhesive layer 13 is located between the second surface 112 and the third surface 141. The vehicle window glass 10a also includes a heat insulation layer 12, which is disposed on the second surface 112 of the first glass layer 11 and / or the third surface 141 of the second glass layer 14, avoiding the first window area 101 and the second window area 102.

[0106] Understandably, in some embodiments, the first glass layer 11, the adhesive layer 13, the heat insulation layer 12, and the second glass layer 14 are stacked sequentially. In other embodiments, the first glass layer 11, the heat insulation layer 12, the adhesive layer 13, and the second glass layer 14 are stacked sequentially. In still other embodiments, the first glass layer 11, the heat insulation layer 12, the adhesive layer 13, the heat insulation layer 12, and the second glass layer 14 are stacked sequentially.

[0107] It should be noted that when the window assembly 100 is installed in the vehicle, the first glass layer 11 faces outwards and the second glass layer 14 faces inwards. The fourth surface 142 is the inner surface 103 of the glass substrate 10.

[0108] Understandably, the first window area 101 and the second window area 102 are not provided with a heat insulation layer 12.

[0109] Optionally, the transmittance of the first glass layer 11 and / or the second glass layer 14 for perpendicularly incident near-infrared light with wavelengths in the range of 800nm-1600nm (inclusive of the endpoints 800nm ​​and 1600nm) is greater than or equal to 90%. Specifically, the perpendicular transmittance of near-infrared light with wavelengths in the range of 840nm-940nm (inclusive of the endpoints 840nm and 940nm) on the first glass layer 11 and / or the second glass layer 14 is greater than or equal to 90%. The perpendicular transmittance of near-infrared light on the first glass layer 11 and / or the second glass layer 14 is the transmittance when near-infrared light is perpendicularly incident on the first glass layer 11 and / or the second glass layer 14, that is, the transmittance through the first glass layer 11 and / or the second glass layer 14 along its thickness direction. For example, the perpendicular transmittance of near-infrared light with a wavelength of 905nm on the first glass layer 11 and / or the second glass layer 14 is greater than or equal to 90%.

[0110] Specifically, the vertical transmittance of near-infrared light with wavelengths in the range of 1500nm-1600nm (inclusive) on the first glass layer 11 and / or the second glass layer 14 is also greater than or equal to 90%. For example, the vertical transmittance of near-infrared light with a wavelength of 1550nm on the first glass layer 11 and / or the second glass layer 14 is greater than or equal to 90%.

[0111] Understandably, in some embodiments, the first glass layer 11 and / or the second glass layer 14 have high near-infrared transmittance. That is, the first glass layer 11 and / or the second glass layer 14 can be high-transmittance glass. Preferably, the first glass layer 11 and / or the second glass layer 14 are ultra-clear glass (i.e., ultra-transparent glass).

[0112] Optionally, the adhesive layer 13 may be made of at least one of the following materials: polyvinyl butyral (PVB), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), and ionic polymer (SGP).

[0113] Optionally, the insulation layer 12 can be, but is not limited to, a silver layer, and the number of silver layers can be, but is not limited to, one or more layers (e.g., two, three, four, five, etc.). When the silver layer is multi-layered, the multiple silver layers are stacked sequentially.

[0114] Optionally, the heat insulation layer 12 is an infrared reflective heat insulation layer (IRR reflective heat insulation layer for short), i.e., an infrared reflective layer.

[0115] Optionally, the Lab value of the insulation layer 12 can be designed according to actual needs, and this application does not impose specific limitations.

[0116] In this embodiment, the glass substrate 10 includes a first glass layer 11 and a second glass layer 14, which improves the strength of the glass substrate 10. Furthermore, a heat insulation layer 12 is disposed between the first glass layer 11 and the second glass layer 14, giving the glass substrate 10 better heat insulation performance. When applied to a vehicle, this results in a lower interior temperature. Moreover, the heat insulation layer 12 is positioned away from the first window area 101 and the second window area 102, which better avoids the heat insulation layer 12 affecting the transmission of optical signals from the first sensor 51 and the second sensor 52, improving the detection accuracy of the first sensor 51 and the second sensor 52, and enhancing the safety and reliability of intelligent driving.

[0117] In some embodiments, the heat insulation layer 12 has a reflectivity of 80% or greater for infrared light with wavelengths from 780 nm to 2500 nm.

[0118] Specifically, the reflectivity of the heat insulation layer 12 for infrared light with wavelengths from 780nm to 2500nm can be, but is not limited to, greater than or equal to 80%, greater than or equal to 81%, greater than or equal to 82%, greater than or equal to 83%, greater than or equal to 84%, greater than or equal to 85%, greater than or equal to 86%, greater than or equal to 87%, greater than or equal to 88%, greater than or equal to 89%, greater than or equal to 90%, greater than or equal to 91%, greater than or equal to 92%, greater than or equal to 93%, greater than or equal to 94%, greater than or equal to 95%, etc.

[0119] In this embodiment, the reflectivity of the heat insulation layer 12 for infrared light with wavelengths from 780nm to 2500nm is too low, which reduces the heat insulation performance of the glass substrate 10. When the window assembly 100 is applied to a vehicle, it cannot effectively block external infrared light, which is not conducive to reducing the temperature inside the vehicle.

[0120] Furthermore, the heat insulation layer 12 has a reflectivity of 85% or greater for infrared light with wavelengths from 780nm to 2500nm. This can better improve the heat insulation performance of the glass substrate 10, so that when the window assembly 100 is applied to a vehicle, it can better reduce the temperature inside the vehicle.

[0121] Furthermore, the heat insulation layer 12 has a reflectivity of 90% or greater for infrared light with wavelengths from 780nm to 2500nm. This can better improve the heat insulation performance of the glass substrate 10, so that when the window assembly 100 is applied to a vehicle, it can better reduce the temperature inside the vehicle.

[0122] Please see Figure 8In some embodiments, the vehicle window glass 10a further includes an ultraviolet absorption layer 15, which is disposed on the glass substrate 10 and covers at least the first window area 101 and / or the second window area 102.

[0123] Understandably, the ultraviolet absorption layer 15 is used to absorb ultraviolet light.

[0124] Optionally, the ultraviolet absorption layer 15 may be disposed only in the first window region 101 and / or the second window region 102.

[0125] Optionally, the ultraviolet absorption layer 15 can also be integrated into the adhesive layer 13, that is, a material with ultraviolet absorption function is added to the adhesive layer 13, so that the adhesive layer 13 and the ultraviolet absorption layer 15 are integrated into one piece.

[0126] In some embodiments, the ultraviolet absorption layer 15 is disposed between the first glass layer 11 and the second glass layer 14.

[0127] In this embodiment, an ultraviolet absorption layer 15 is provided in the first window area 101 and / or the second window area 102 of the glass substrate 10. This can reduce the transmittance of ultraviolet light in the first window area 101 and / or the second window area 102, which can protect the sensor assembly 50 and better prevent long-term ultraviolet radiation, thereby preventing the sensor assembly 50 from aging or being damaged, and thus improving the service life of the sensor assembly 50.

[0128] In some embodiments, the ultraviolet absorption layer 15 has an absorption rate of 98% or greater for ultraviolet light with wavelengths from 380 nm to 410 nm.

[0129] Understandably, the transmittance of the ultraviolet absorption layer 15 to ultraviolet light with wavelengths from 380 nm to 410 nm is less than or equal to 2%.

[0130] Specifically, the absorption rate of the ultraviolet absorption layer 15 for ultraviolet light with wavelengths from 380nm to 410nm can be, but is not limited to, 98.2%, 98.4%, 98.6%, 98.8%, 99%, 99.2%, 99.4%, 99.6%, 99.8%, etc.

[0131] In this embodiment, the absorption rate of the ultraviolet absorption layer 15 for ultraviolet light with wavelengths from 380nm to 410nm is too low. As a result, too much ultraviolet light is incident on the sensor assembly 50 through the first window region 101 and / or the second window region 102 of the glass substrate 10. This makes the sensor assembly 50 prone to aging under long-term ultraviolet irradiation, thus reducing the service life of the sensor assembly 50.

[0132] Please see Figure 9 and Figure 10 In some embodiments, the glass substrate 10 further includes an antireflection film 16, which is disposed on the inner surface 103 of the glass substrate 10 and at least covers the first window area 101 and / or the second window area 102.

[0133] Understandably, the antireflective film 16 is disposed on the side of the second glass layer 14 opposite to the first glass layer 11, for increasing the reflection of light by the glass substrate 10. It is also understood that the antireflective film 16 is disposed on the fourth surface 142.

[0134] Optionally, the antireflective coating 16 can be, but is not limited to, a near-infrared antireflective layer. The antireflective coating 16 can be applied to the surface or side of the second glass layer 14 away from the first glass layer 11 by means of lamination, patching, or coating.

[0135] It should be noted that the antireflective coating 16 is transparent to visible light.

[0136] In this embodiment, by providing an antireflection film 16 on the side of the second glass layer 14 away from the first glass layer 11, the reflectivity of the glass substrate 10 to the infrared light emitted by the lidar in the sensor assembly 50 can be reduced, thereby increasing the intensity of the lidar signal and improving the accuracy of lidar detection.

[0137] Please see Figure 11 and Figure 12 In some embodiments, the bracket 21 has interconnected mounting holes 211 and recesses 215, the mounting holes 211 being used to mount the sensor assembly 50. The bracket 21 also has a bottom wall 216, a first side wall 217, a second side wall 218, and a third side wall 219 surrounding the recesses 215. The first side wall 217, the second side wall 218, and the third side wall 219 are sequentially bent and connected, and are all bent and connected to the bottom wall 216. The mounting hole 211 penetrates the second side wall 218. The mounting assembly 20 also includes a light-shielding film 22, which is disposed on at least one of the bottom wall 216, the first side wall 217, and the third side wall 219. The light-shielding film 22 is used to prevent stray light from entering the mounting hole 211, thereby improving the detection accuracy of the sensor assembly 50 within the mounting hole 211.

[0138] It should be noted that the recess 215 is closer to the glass substrate 10 than the mounting hole 211.

[0139] Optionally, the recess 215 extends through the surface of the support 21 facing the glass substrate 10.

[0140] Understandably, only one of the bottom wall 216, the first side wall 217, and the third side wall 219 may be provided with a light-shielding film 22, for example, the first side wall 217 may be provided with a light-shielding film 22; only two of the bottom wall 216, the first side wall 217, and the third side wall 219 may be provided with a light-shielding film 22; or all of the bottom wall 216, the first side wall 217, and the third side wall 219 may be provided with a light-shielding film 22. When all of the bottom wall 216, the first side wall 217, and the third side wall 219 are provided with a light-shielding film 22, stray light can be better prevented from entering the sensor assembly 50 in the mounting hole 211.

[0141] The first window area 101 and the second window area 102 of the glass substrate 10 lack a heat insulation layer 12, thereby increasing the amount of light entering the first window area 101 and the second window area 102 of the glass substrate 10. This increases stray light entering the camera of the sensor assembly 50, making the camera prone to overexposure or causing excessive stray light to affect image quality, thus reducing the accuracy and precision of the sensor assembly 50. In this embodiment, by providing a light-shielding film 22 on at least one of the bottom wall 216, the first side wall 217, and the third side wall 219, the light-shielding film 22 can reflect light, such as visible light, multiple times, thereby reducing stray light entering the sensor assembly 50 through the mounting hole 211, and thus improving the accuracy and precision of the sensor assembly 50.

[0142] In some embodiments, the diffuse reflectance of the light-shielding film 22 is less than or equal to 2%.

[0143] Specifically, the diffuse reflectance of the light-shielding film 22 can be, but is not limited to, 2%, 1.8%, 1.6%, 1.4%, 1.2%, 1.0%, 0.8%, 0.6%, 0.4%, etc.

[0144] In this embodiment, the lower the diffuse reflectance of the light-shielding film 22, the better the light incident on the light-shielding film 22 can be attenuated by multiple reflections upon entering the glass substrate 10, thereby reducing the probability of stray light entering the camera in the sensor assembly 50 and improving the detection accuracy of the sensor assembly 50.

[0145] In some embodiments, the surface of the light-shielding film 22 facing the sink 215 has at least one of a serrated structure and a honeycomb structure.

[0146] Alternatively, the light-blocking film 22 can be formed using special light-absorbing materials through methods such as flocking or painting.

[0147] Understandably, the surface of the light-shielding film 22 has at least one of a serrated structure or a honeycomb structure.

[0148] In this embodiment, at least one of a sawtooth structure and a honeycomb structure is provided on the surface of the light-shielding film 22. This allows the light-shielding film 22 to perform more reflections and attenuation on stray light, preventing stray light from entering the camera of the sensor assembly 50 and improving the detection accuracy of the sensor assembly 50.

[0149] Optionally, the light-shielding film 22 has high-temperature resistance. Optionally, the temperature that the light-shielding film 22 can withstand is greater than or equal to 110°C. That is, the light-shielding film 22 will not decompose and produce volatile organic compounds (VOCs) or semi-volatile organic compounds (SVOCs) at temperatures greater than or equal to 110°C. Specifically, the high temperatures that the light-shielding film 22 can withstand can be, but are not limited to, 110°C, 115°C, 120°C, 125°C, 130°C, 135°C, 140°C, and 145°C. When the temperature that the light-shielding film 22 can withstand is too low, it is easy to decompose and produce volatile organic compounds (VOCs) or semi-volatile organic compounds (SVOCs). Volatile organic compounds (VOCs) or semi-volatile organic compounds (SVOCs) will reduce the performance of the camera and reduce the shooting quality of the camera, thereby affecting intelligent driving.

[0150] Please see again Figure 2 Optionally, the angle α between the bottom wall 216 and the surface of the second glass layer 14 facing away from the first glass layer 11 is in the range of 10°≤α≤20°. Specifically, the angle α between the bottom wall 216 and the surface of the second glass layer 14 facing away from the first glass layer 11 can be, but is not limited to, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, etc. Since the light-shielding film 22 is mostly located on the bottom wall 216 of the support 21, an angle α between the bottom wall 216 and the surface of the second glass layer 14 facing away from the first glass layer 11 that is too small or too large is not conducive to reducing the diffuse reflectance of the light-shielding film 22, and is not conducive to improving the detection accuracy of the sensor assembly 50.

[0151] Please see again Figure 2 Optionally, the included angle β between the second sidewall 218 and the surface of the second glass layer 14 facing away from the first glass layer 11 is in the range of 60°≤β≤80°. Specifically, the included angle β between the second sidewall 218 and the surface of the second glass layer 14 facing away from the first glass layer 11 can be, but is not limited to, 60°, 62°, 64°, 66°, 68°, 70°, 72°, 74°, 76°, 78°, 80°, etc. If the included angle β between the second sidewall 218 and the surface of the second glass layer 14 facing away from the first glass layer 11 is too small or too large, it will reduce the appearance of the vehicle using the window assembly 100, or hinder the sensor assembly 50 from detecting surrounding objects over a wider range, thus hindering the improvement of sensor detection accuracy.

[0152] Optionally, when the glass substrate 10 includes a first glass layer 11, an adhesive layer 13, and a second glass layer 14, the first heating element 31 may be disposed on at least one of the second surface 112, the third surface 141, and the fourth surface 142 of the glass substrate 10.

[0153] Optionally, the distance between the light-shielding film 22 and the glass substrate 10 is less than or equal to 30 mm, and the heating component 30 includes at least one of a first heating element 31 and a second heating element 32. The first heating element 31 avoids the first window area 101 and is at least partially disposed in the second window area 102. The first heating element 31 at least corresponds to heating the non-overlapping area of ​​the second window area 102, and the second heating element 32 is disposed on the light-shielding film 22.

[0154] It should be noted that when the window assembly 100 is applied to a vehicle and the sensor assembly 50 is installed in the mounting hole 211, the area of ​​the glass substrate 10 other than the first window area 101 can be heated by at least one of the first heating element 31 disposed on the glass substrate 10 and the second heating element 32 disposed on the light-shielding film 22 to achieve defogging or defrosting. The area of ​​the glass substrate 10 at the first window area 101 can be heated by the second heating element 32 at the location of the light-shielding film 22 to achieve defogging or defrosting.

[0155] It should be noted that when the heating assembly 30 includes a second heating element 32, the second heating element 32 can be disposed on the bottom wall 216 of the light-shielding film 22 and the sink 215, and on the first side.

[0156] Between wall 217 and third side wall 219. When the heating assembly 30 includes a first heating element 31, the first heating element 31 may be disposed between the first glass layer 11 and the second glass layer 14, or it may be disposed on the side of the second glass layer 14 away from the first glass layer 11.

[0157] In this embodiment, by providing a first heating element 31 on the light-shielding film 22 and / or providing a heating component 30 on at least one of the areas of the glass substrate 10 other than the first window area 101, defogging and defrosting can be performed simultaneously by heating the glass substrate 10 and the mounting component 20, thereby achieving better defogging and defrosting effects. In addition, the heating component 30 is not provided at the position of the glass substrate 10 corresponding to the first window area 101, which can better avoid the heating component 30 affecting the transmission of the lidar signal of the sensor component 50 and improve the accuracy of lidar detection.

[0158] It should be noted that the first heating element 31 may also be provided in areas of the glass substrate 10 other than the first window area 101 and the second window area 102, and this application does not make specific limitations on this.

[0159] In other embodiments, the distance between the light-shielding film 22 and the glass substrate 10 is greater than or equal to 30 mm, and the heating component 30 includes a first heating element 31, which is at least disposed in the first window area 101 and the second window area 102 of the glass substrate 10.

[0160] It should be noted that the first heating element 31 may also be provided in areas of the glass substrate 10 other than the first window area 101 and the second window area 102, and this application does not make specific limitations on this.

[0161] In this embodiment, the glass substrate 10 is far from the light-shielding film 22. If the second heating element 32 is provided at the position of the light-shielding film 22 and the first heating element 31 is not provided at the glass substrate 10, the defogging and defrosting effect of the glass substrate 10 will be poor. By providing the first heating element 31 at the first window area 101 and the second window area 102 of the glass substrate 10, the glass substrate 10 can be defogging better, and the defogging and defrosting effect can be improved.

[0162] Please see again Figure 3 In some embodiments, the refractive power of the first window region 101 on the glass substrate 10 is less than or equal to the refractive power of the second window region 102 excluding the overlapping region.

[0163] Understandably, the refractive power of the overlapping area is less than or equal to the refractive power of the second window area 102 excluding the overlapping area.

[0164] Optionally, in this embodiment, the first window area 101 is the transmission area of ​​the optical signal of the lidar. The second window area 102 is the transmission area of ​​the optical signal of the camera. In other words, the first sensor 51 is the lidar, and the second sensor 52 is the camera.

[0165] Replacing long-focus cameras with radar can solve the pain point of camera usage in bright environments.

[0166] In this embodiment, the refractive power of the first window area 101 on the glass substrate 10 is less than or equal to the refractive power of the second window area 102 excluding the overlapping area. This allows the first sensor 51 to be a lidar and correspond to the first window area 101, and the second sensor 52 to be a camera and correspond to the second window area 102. By using a lidar instead of a telephoto camera, the pain point of using a camera in low-light environments can be solved, the detection accuracy of the first sensor 51 and the second sensor 2 can be improved, and driving safety can be enhanced.

[0167] In some embodiments, the refractive power of the first window region 101 and the second window region 102 on the glass substrate 10 is less than or equal to 100 mdpt.

[0168] Specifically, the refractive power of the first window area 101 and the second window area 102 on the glass substrate 10 can be, but is not limited to, ≤100mdpt, or ≤95mdpt, or ≤90mdpt, or ≤85mdpt, or ≤80mdpt, or ≤75mdpt, or ≤70mdpt, or ≤65mdpt, or ≤60mdpt, or ≤55mdpt, or ≤50mdpt.

[0169] In this embodiment, if the refractive power of the first window area 101 and the second window area 102 on the glass substrate 10 is too large, it will reduce the detection accuracy of the first sensor 51 and the second sensor 52. Controlling the refractive power of the first window area 101 and the second window area 102 within a certain value can better improve the detection accuracy of the first sensor 51 and the second sensor 52 and improve the safety of intelligent driving.

[0170] Please see Figure 13 This application embodiment also provides a vehicle 200, which includes a body 210 and a window assembly 100 as described in this application embodiment, wherein the window assembly 100 is mounted on the body 210.

[0171] The vehicle 200 in this application embodiment can be, but is not limited to, a car, sedan, bus, truck, train, or other means of transportation.

[0172] For a detailed description of other aspects of the window assembly 100, please refer to the description of the corresponding part of the above embodiment, which will not be repeated here.

[0173] Optionally, the window assembly 100 can be directly fixed to the vehicle body 210, or it can be movably mounted on the vehicle body 210.

[0174] In this application, the terms "embodiment" and "implementation" mean that a specific feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of this application. The appearance of these phrases in various locations throughout the specification does not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments.
