Description

window assembly and vehicle

[0001] This application claims priority to Chinese Patent Application No. 202411561438.7, filed on November 4, 2024, entitled "Window Assembly and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of vehicle technology, specifically to a window assembly and a vehicle. Background Technology

[0003] To prevent excessive temperature differences between the vehicle's interior and exterior, which could lead to fogging or frost on the windows, a transparent conductive film is typically installed on the windows. By energizing this film, it heats up, thus defogging, defrosting, and de-icing the windows. Furthermore, vehicle interiors are commonly equipped with sensor assemblies, including sensors (such as cameras), to assist in the vehicle's autonomous driving modes. The windows also have data acquisition areas to allow signals from these sensor assemblies to pass through.

[0004] To ensure that the transparent conductive film does not obstruct the signal from the sensor components, it is usually removed from the information acquisition area. However, this can cause water vapor, frost, or ice to form in the information acquisition area when there is a large temperature difference between the inside and outside of the vehicle. This can severely hinder the sensor from obtaining accurate signals through the information acquisition area on the windshield. Therefore, a defogging and defrosting structure is generally installed in the information acquisition area.

[0005] However, in related technologies, sensor components may include multiple sensors, which correspond to different areas of the information collection area. How to achieve the purposes of defrosting, defogging, and de-icing is an urgent problem to be solved. Summary of the Invention

[0054] In related technologies, to prevent excessive temperature differences between the vehicle's interior and exterior environments, which could lead to fogging or frost formation on the windows, a transparent conductive film is typically applied to the windows. By energizing the transparent conductive film, it heats up, thus achieving the purpose of defogging, defrosting, and de-icing the windows. Furthermore, vehicle interiors commonly house sensor components, which may include multiple sensors (such as cameras and lidar) to assist in autonomous driving modes. The windows have multiple signal transmission zones for the sensor components to transmit signals. To ensure the transparent conductive film does not obstruct the sensor signals, these zones are usually removed. However, this can cause fogging, frost, or ice to form in these zones when there is a significant temperature difference between the vehicle's interior and exterior, severely hindering the sensor components from obtaining accurate signals through these zones. Therefore, defogging and defrosting structures are typically installed in these signal transmission zones. However, the sensor assembly includes multiple sensors, which correspond to multiple signal transmission areas on the car window glass. How to achieve the purpose of defrosting, defogging, and de-icing on multiple signal transmission areas on the car window glass is an urgent problem to be solved.

[0055] In this embodiment, a vehicle window assembly including a first sensor and a second sensor is used as an example. The first sensor corresponds to a first signal transmission area, and the second sensor corresponds to a second signal transmission area. A heating element and a busbar are installed on the vehicle window glass. By arranging the busbar and heating element, the heating of the first and second signal transmission areas can be controlled simultaneously or individually. That is, different arrangements of the heating element and busbar on the vehicle window glass can form different circuits to ensure the heating performance of the first and second signal transmission areas, so as to achieve the purpose of defrosting, defogging, and de-icing in the first and second signal transmission areas.

Detailed Implementation

[0069] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0070] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Furthermore, "multiple" in this application refers to two or more.

[0071] Please refer to Figure 1, which is a structural schematic diagram of the vehicle provided in an embodiment of this application.

[0072] An embodiment of this application provides a vehicle 1000. The vehicle 1000 may be, but is not limited to, a sedan, a multi-purpose vehicle (MPV), a sport / suburban utility vehicle (SUV), an off-road vehicle (ORV), a pickup truck, a van, a bus, a truck, etc.

[0073] For ease of description, in this application, the width direction of the vehicle 1000 shown in Figure 1 is defined as the X-axis direction, the length direction as the Y-axis direction, and the height direction as the Z-axis direction, wherein the X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0074] It should be noted that the directional terms such as "top," "bottom," "left," "right," "front," and "rear" mentioned in the description of this application are based on the orientation of the vehicle 1000 shown in Figure 1 of the specification. The forward direction in the length direction of the vehicle 1000 is taken as the positive direction of the X-axis, the direction from left to right in the width direction of the vehicle 1000 is taken as the positive direction of the Y-axis, and the direction away from the ground in the width direction of the vehicle 1000 is taken as the positive direction of the Z-axis.

[0075] As shown in Figure 1, the vehicle 1000 includes a vehicle body 200, a window assembly, and a power supply (not shown). The window assembly includes a window glass 100 and sensor components 300. The window glass 100 is connected to the vehicle body 200 and installed at an opening in the vehicle body 200. Considering application scenarios that provide more sensor components 300 for the vehicle 1000, the window glass 100 can be, but is not limited to, the windshield, side windows, rear windshield, and sunroof of the vehicle 1000. In this embodiment, only the windshield is used as an example for illustration.

[0076] As shown in Figures 1 to 11, the sensor assembly 300 is disposed on the inner side of the vehicle window glass 100. The sensor assembly 300 includes a first sensor 310 and a second sensor 320, which are spaced apart. The vehicle window glass 100 includes a first signal transmission area 21 and a second signal transmission area 22. The first signal transmission area 21 is the signal transmission area of ​​the first sensor 310 on the vehicle window glass 100, and the second signal transmission area 22 is the signal transmission area of ​​the second sensor 320 on the vehicle window glass 100. The vehicle window glass 100 of this application also includes a heating element 80, which is at least disposed within the first signal transmission area 21 and the second signal transmission area 22. This application can achieve functions such as defrosting and defogging of the first signal transmission area 21 and the second signal transmission area 22 by electrically heating the heating element 80.

[0077] In this application, the first signal transmission area 21 and the second signal transmission area 22 can be spaced apart along the horizontal direction of the vehicle window glass 100. Alternatively, the first signal transmission area 21 and the second signal transmission area 22 can be spaced apart along the vertical direction of the vehicle window glass 100. Alternatively, the first signal transmission area 21 and the second signal transmission area 22 are not limited to the aforementioned relative positional relationship, such as the first signal transmission area 21 being spaced diagonally above or diagonally below the second signal transmission area 22. Alternatively, the first signal transmission area 21 and the second signal transmission area 22 can partially overlap or completely overlap.

[0078] Please refer to Figures 3 to 5, 7, 8, 10, and 11. It should be noted that the dashed lines in Figures 3 to 5, 7, 8, 10, and 11 represent the boundary between the first viewing angle region 101 of the first sensor 310 and the second viewing angle region 102 of the second sensor 320.

[0079] It should be noted that the first viewing angle region 101 mentioned above refers to the area actually used by the first sensor 310, and the second viewing angle region 102 refers to the area actually used by the second sensor 320. The first viewing angle region 101 and the second viewing angle region 102 can be the entire first signal transmission area 21 and the second signal transmission area 22, or they can be a part of them. The size of the first signal transmission area 21 and the second signal transmission area 22 is set according to the field of view of the first sensor 310 and the second sensor 320, respectively. For example, the field of view of the first sensor 310 is smaller than the field of view of the second sensor 320, the first viewing angle region 101 of the first sensor 310 is smaller than the second viewing angle region 102 of the second sensor 320, and the area of ​​the first signal transmission area 21 is smaller than the area of ​​the second signal transmission area 22.

[0080] In this embodiment, the first sensor 310 can be a camera, and the second sensor 320 can be a LiDAR. In some embodiments, the first sensor 310 may not be limited to a camera, but may also be one of a near-infrared camera, thermal imager, gesture detection sensor, LiDAR, rain sensor, ETC (Electronic Toll Collection), etc. Similarly, the second sensor 320 may not be limited to LiDAR, but may also be one of a near-infrared camera, thermal imager, gesture detection sensor, camera, rain sensor, ETC (Electronic Toll Collection), etc. Depending on the application and customer requirements, the sensor assembly 300 may also be not limited to the first sensor 310 and the second sensor 320.

[0081] In this application, both the first signal transmission area 21 and the second signal transmission area 22 can be located on the side of the vehicle window 100 near the top of the vehicle 1000.

[0082] Please refer to Figures 2 and 3 together. Figure 2 is a simplified cross-sectional view of the vehicle window glass shown in Figure 1, and Figure 3 is a partial structural schematic diagram of the vehicle window glass shown in Figure 1.

[0083] The vehicle window glass 100 described in this application is a laminated glass structure. The vehicle window glass 100 includes an outer glass panel 30, an inner glass panel 40, and an intermediate layer 50. The intermediate layer 50 is bonded between the outer glass panel 30 and the inner glass panel 40. A heating element 80 is fixed between the outer glass panel 30 and the sensor assembly 300. Along the thickness direction of the vehicle window glass 100, the outer glass panel 30, the intermediate layer 50, and the inner glass panel 40 are sequentially stacked and connected. When the vehicle window glass 100 is installed on the vehicle body 200, the outer glass panel 30 faces the outside of the vehicle 1000, and the inner glass panel 40 faces the inside of the vehicle 1000.

[0084] In this embodiment, the window glass 100 is curved. Both the outer glass panel 30 and the inner glass panel 40 are subjected to high-temperature bending forming at at least 500°C. In other embodiments, the window glass 100 may also be flat. The shape of the window glass 100 is not limited to the shape described above; it can be any shape that meets the usage requirements of the vehicle 1000. This embodiment does not impose strict limitations on the shape of the window glass 100.

[0085] The outer glass panel 30 includes a first surface 31 and a second surface 32. The first surface 31 and the second surface 32 are disposed opposite to each other along the thickness direction of the outer glass panel 30. When the vehicle window glass 100 is installed on the vehicle body 200, the first surface 31 of the outer glass panel 30 faces the outside of the vehicle 1000 and serves as the outer surface of the vehicle window glass 100. The second surface 32 of the outer glass panel 30 faces the intermediate layer 50.

[0086] The thickness of the outer glass panel 30 can be from 1.6 mm to 5.0 mm. For example, the thickness of the outer glass panel 30 can be, but is not limited to, 1.6 mm, 1.8 mm, 2.1 mm, 2.6 mm, 3.2 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, or other values ​​between 1.6 mm and 5.0 mm. In one possible embodiment, the thickness of the outer glass panel 30 is 1.8 mm. In another possible embodiment, the thickness of the outer glass panel 30 is 2.1 mm.

[0087] The outer glass plate 30 is made of materials including, but not limited to, soda-lime glass or aluminosilicate glass. The outer glass plate 30 can be clear glass, ultra-clear glass, ordinary green glass, solar green glass, etc. In this embodiment, since the sensor assembly 300 includes a lidar, the signal emitted by the lidar needs to pass through the outer glass plate 30. Therefore, the outer glass plate 30 can be ordinary clear glass with a transmittance of 75% to 85% for visible light with wavelengths between 800 nm and 1600 nm. Preferably, the outer glass plate 30 can be ultra-clear glass with a transmittance of 85% to 95% for infrared light with wavelengths between 800 nm and 2100 nm.

[0088] The inner glass panel 40 includes a third surface 41 and a fourth surface 42. The third surface 41 and the fourth surface 42 are arranged opposite to each other along the thickness direction of the inner glass panel 40. When the window glass 100 is installed on the vehicle body 200, the third surface 41 of the inner glass panel 40 faces the intermediate layer 50. The fourth surface 42 of the inner glass panel 40 faces the interior of the vehicle 1000. The fourth surface 42 serves as the inner surface of the window glass 100.

[0089] The thickness of the inner glass plate 40 can be from 0.7 mm to 5.0 mm. For example, the thickness of the inner glass plate 40 can be, but is not limited to, 0.7 mm, 1.1 mm, 1.6 mm, 1.8 mm, 2.1 mm, 2.6 mm, 3.2 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, or other values ​​between 0.7 mm and 5.0 mm. In one possible embodiment, the thickness of the inner glass plate 40 is 1.8 mm. In another possible embodiment, the thickness of the outer glass plate 30 is 2.1 mm.

[0090] The inner glass plate 40 is made of materials including, but not limited to, soda-lime glass or aluminosilicate glass. The inner glass plate 40 can be clear glass, ultra-clear glass, ordinary green glass, solar green glass, etc. In this embodiment, since the sensor assembly 300 includes a lidar, the signal emitted by the lidar needs to pass through the inner glass plate 40. Therefore, the inner glass plate 40 can be ordinary clear glass with a transmittance of 75% to 85% for visible light with wavelengths between 800 nm and 1600 nm. Preferably, the inner glass plate 40 can be ultra-clear glass with a transmittance of 85% to 95% for infrared light with wavelengths between 800 nm and 2100 nm.

[0091] The intermediate layer 50 connects the second surface 32 of the outer glass plate 30 and the third surface 41 of the inner glass plate 40. The intermediate layer 50 is used to bond and fix the outer glass plate 30 and the inner glass plate 40 together.

[0092] In this embodiment, the intermediate layer 50 can be a single-layer structure or a multi-layer structure. The intermediate layer 50 can be colorless or partially colored. The intermediate layer 50 can be a thermoplastic intermediate layer 50. The material of the intermediate layer 50 can be polycarbonate (PC), polyvinyl chloride (PVC), polyvinyl butyral (PVB), ethylene-co-vinyl acetate (EVA), polyamide (PA), polymethyl methacrylate (PMMA), polyurethane reactive (PUR), ionomer film (Sentry Glas Plus, SGP), etc. This application does not impose specific limitations on the layer structure and material of the intermediate layer 50.

[0093] In one possible implementation, an infrared absorber is added to the intermediate layer 50, giving it the function of absorbing heat and light. In another possible implementation, the intermediate layer 50 may include at least two layers, one containing a higher content of plasticizer to improve the sound insulation performance of the window glass 100; the other layer is wedge-shaped to enable the window glass 100 to function as a HUD. In yet another possible implementation, the intermediate layer 50 is partially tinted to act as a shielding layer, protecting interior parts of the vehicle 1000 or blocking sunlight. For example, the intermediate layer 50 may have a tinted area at the top of the corresponding window glass 100, where the tinted area corresponding to the shielding area 12 can be joined with the untinted transparent area of ​​the intermediate layer 50. This tinted area can reduce the interference of sunlight on the human eye. As another example, the intermediate layer 50 may have a tinted area at the bottom of the corresponding window glass 100, which can be joined with the untinted transparent area of ​​the intermediate layer 50. This tinted area is used to shield and protect interior parts of the vehicle 1000. For example, the intermediate layer 50 has two colored areas at the top and bottom of the corresponding window glass 100. The two colored areas are located on opposite sides of the uncolored transparent area in the middle of the intermediate layer 50 in the vertical direction, and are spliced ​​with the uncolored transparent area in the middle of the intermediate layer 50.

[0094] As shown in Figures 3 to 11, the vehicle window glass 100 described in this application further includes a main viewing area 11 and a shielding area 12. The shielding area 12 is arranged circumferentially around the main viewing area 11. The main viewing area 11 is a transparent area used by occupants of the vehicle to observe the external environment through the main viewing area 11, and for light transmission between the interior and exterior of the vehicle 1000. The main viewing area 11 is the window of the vehicle 1000. In some embodiments, the main viewing area 11 may also be partially used for a head-up display (HUD), that is, as a HUD area to display information such as driving speed, dynamic navigation, and business district information.

[0095] The shielding area 12 is used to provide a shielding layer or a tinted intermediate layer to prevent visible light from passing through the window glass 100. In this embodiment, the shape of the main viewing area 11 matches the shape of the window glass 100. The shielding area 12 is generally an annular frame shape. The outer edge of the shielding area 12 is the outer edge of the window glass 100, and the inner edge of the shielding area 12 is connected to the peripheral side of the main viewing area 11. Alternatively, the inner edge of the shielding area 12 is connected to a portion of the peripheral side of the main viewing area 11 and a portion of the peripheral side of the first signal transmission area 21 and the second signal transmission area 22.

[0096] As shown in Figures 3 to 11, the vehicle window glass 100 also includes a transparent conductive film 60. The transparent conductive film 60 is disposed within the main viewing area 11 of the vehicle window glass 100, completely avoiding the first signal transmission area 21 and the second signal transmission area 22 of the vehicle window glass 100, and is located between the outer glass panel 30 and the inner glass panel 40. The transparent conductive film 60 can be laminated on either the outer glass panel 30 or the inner glass panel 40. Specifically, the transparent conductive film 60 can cover the second surface 32 of the outer glass panel 30 located in the main viewing area 11, or it can cover the third surface 41 of the inner glass panel 40 located in the main viewing area 11. This application does not impose any limitations on this.

[0097] The transparent conductive film 60 can be directly deposited on the outer glass plate 30 or the inner glass plate 40 using methods not limited to chemical vapor deposition (CVD) or physical vapor deposition (PVD). For example, the transparent conductive film 60 can be deposited on the second surface 32 or the third surface 41 by magnetron sputtering.

[0098] It should be noted that when the transparent conductive film 60 is disposed on the second surface 32 or the third surface 41, since the transparent conductive film 60 has a reflective effect on solar energy, the outer glass panel 30 is preferably made of clear glass or ultra-clear glass to increase the reflection of solar energy by the window glass 100, reduce the total energy transmittance of solar energy, and provide heat insulation. Simultaneously, if a busbar and power supply are added to the transparent conductive film 60, the transparent conductive film 60 will possess conductive properties. By energizing the transparent conductive film 60, it heats up, thereby achieving the purpose of defogging, defrosting, and de-icing the window glass 100.

[0099] The transparent conductive film 60 can withstand high-temperature heat treatment, such as heat treatment processes involving bending or tempering. The transparent conductive film 60 may include a metal layer, a metal alloy layer, or a metal oxide layer. The metal layer can be made of materials such as gold (Au), silver (Ag), copper (Cu), aluminum (Al), or molybdenum (Mo). The metal oxide layer can be made of materials such as indium tin oxide, fluorine-doped tin dioxide, aluminum-doped tin dioxide, gallium-doped tin dioxide, boron-doped tin dioxide, tin-zinc oxide, or antimony-doped tin oxide. For example, when the transparent conductive film 60 includes a silver layer or a silver alloy layer, the silver layer or silver alloy layer is located between at least two dielectric layers, wherein the dielectric layers contain zinc oxide (ZnO), tin oxide (SnO2), indium oxide (In2O3), and titanium oxide (TiO2). x At least one of the following: silicon oxide (SiO2), aluminum oxide (Al2O3), silicon nitride (Si3N4), silicon carbide (SiC), aluminum nitride (AlN), or titanium metal layer.

[0100] The vehicle window glass 100 also includes multiple busbars. In this application, the busbars include a first busbar 70 and a second busbar 71 spaced apart, and both the first busbar 70 and the second busbar 71 are electrically connected to the transparent conductive film 60. In this application, the first busbar 70 and the second busbar 71 are spaced apart along opposite sides of the transparent conductive film 60. Specifically, the first busbar 70 and the second busbar 71 are located on opposite sides of the vehicle window glass 100 in the vertical direction, and both the first busbar 70 and the second busbar 71 are located in the shielding area 12, so that the first busbar 70 and the second busbar 71 are not visible to the naked eye from outside the vehicle 1000, thus improving the overall aesthetics of the vehicle window glass 100. In this application, the first busbar 70 and the second busbar 71 are both located between the outer glass panel 30 and the inner glass panel 40. It should be noted that the first busbar 70 and the second busbar 71 are both stacked on the transparent conductive film 60.

[0101] The first busbar 70 is located on the side of the shielded area 12 near the top of the vehicle 1000. The distance between the first busbar 70 and the upper edge of the window glass 100 (i.e., the outer edge of the window glass 100 near the top of the vehicle 100) is 6 to 30 mm. For example, the distance between the first busbar 70 and the upper edge of the window glass 100 can be, but is not limited to, 6 mm, 10 mm, 15 mm, 20 mm, 30 mm, or other values ​​between 6 and 30 mm. The material of the first busbar 70 can be, but is not limited to, metal foil, conductive silver paste, etc.

[0102] The second busbar 71 is located on the side of the shielded area 12 near the bottom of the vehicle 1000. The distance between the second busbar 71 and the lower edge of the window glass 100 (i.e., the outer edge of the window glass 100 near the bottom of the vehicle 100) is 6 to 30 mm. For example, the distance between the second busbar 71 and the lower edge of the window glass 100 can be, but is not limited to, 6 mm, 10 mm, 15 mm, 20 mm, 30 mm, or other values ​​between 6 and 30 mm. The material of the second busbar 71 can be, but is not limited to, metal foil, conductive silver paste, etc.

[0103] The vehicle window glass 100 also includes multiple connectors 73. These connectors 73 are located on a first busbar 70 and a second busbar 71. The connectors 73 are used for electrical connection to the positive or negative terminal of the vehicle's power supply. For example, the first busbar 70 has two connectors 73. These two connectors 73 are respectively connected to the positive and negative terminals of the power supply. Alternatively, both connectors 73 on the first busbar 70 may be connected to the positive terminal or both to the negative terminal. The second busbar 71 also has two connectors 73. These two connectors 73 are respectively connected to the positive and negative terminals of the power supply. Alternatively, both connectors 73 on the second busbar 71 may be connected to the positive terminal or both to the negative terminal. Therefore, the power supply, the first busbar 70, the transparent conductive film 60, and the second busbar 71 form a heating field for the main viewing area 11. It is understandable that the power supply can energize the first busbar 70 and the second busbar 71. The current will flow through the transparent conductive film 60 between the first busbar 70 and the second busbar 71, causing the transparent conductive film 60 to heat up under the action of the current and generate heat to heat the main viewing area 11, thereby achieving the purpose of defrosting, defogging, and de-icing the main viewing area 11.

[0104] In this application, the first busbar 70 and / or the second busbar 71 are electrically connected to the heating element 80. The power supply, the first busbar 70 and / or the second busbar 71, and the heating element 80 form a heating field for the first signal transmission area 21 and the second signal transmission area 22. It can be understood that the power supply can energize the first busbar 70 and / or the second busbar 71, and the current will flow through the heating element 80 between the first busbar 70 and / or the second busbar 71, causing the heating element 80 to heat up under the action of the current and generate heat to heat the first signal transmission area 21 and the second signal transmission area 22, thereby achieving the purpose of defrosting, defogging, and de-icing the first signal transmission area 21 and the second signal transmission area 22.

[0105] In some embodiments, the window glass 100 further includes a shielding layer 90. The shielding layer 90 is stacked around the periphery of the second surface 32 of the outer glass panel 30 or the third surface 41 of the inner glass panel 40. The shielding layer 90 covers the shielding area 12 of the window glass 100. Specifically, the shielding layer 90 completely overlaps with the shielding area 12 (the dimensions of the shielding layer 90 in the width and length directions are equal to the dimensions of the shielding area 12 in the width and length directions, respectively). The shielding layer 90 avoids the first signal transmission area 21, the second signal transmission area 22, and the main viewing area 11. In other embodiments, the shielding layer 90 may also partially overlap with the shielding area 12 (the dimensions of the shielding layer 90 in the width and length directions are smaller than the dimensions of the shielding area 12 in the width and length directions, respectively).

[0106] The material of the shielding layer 90 is typically ink, such as ceramic ink or ultraviolet ink. The visible light transmittance of the shielding layer 90 is less than or equal to 5.0%, preferably less than or equal to 1.5%. The shielding layer 90 can be used to shield and protect the parts inside the vehicle 1000. On the one hand, the shielding layer 90 can shield the parts inside the vehicle, improving the overall aesthetics from the outside of the vehicle 1000. On the other hand, the shielding layer 90 serves to block sunlight, preventing the parts inside the vehicle 1000 from being damaged by direct sunlight, thus extending the service life of the parts inside the vehicle 1000 and improving the local adhesion of the parts inside the vehicle 1000 to the window glass 100.

[0107] The heating element 80 can be a heating wire. The heating wire can be enameled wire, with the inner layer material being one or more conductor materials such as copper wire, aluminum wire, or alloy wire, and the outer layer material being one or more insulating materials such as polyurethane (PUR) or polyimide (PI). The wire diameter can range from 0.08 mm to 0.2 mm (including the endpoint values ​​of 0.08 mm and 0.2 mm). The resistance range of the enameled wire can range from 0.5 Ω / m to 3.7 Ω / m (including the endpoint values ​​of 0.5 Ω / m and 3.7 Ω / m). Preferably, the wire diameter range is 0.1 mm to 0.15 mm (including the endpoint values ​​of 0.1 mm and 0.15 mm). The resistance range is 0.9 Ω / m to 2.33 Ω / m (including the endpoint values ​​of 0.9 Ω / m and 2.33 Ω / m). The enameled wire can be directly arranged on the intermediate layer 50 through a crimping process.

[0108] When the heating element 80 is a heating wire, it can also be a silver paste printing line. The silver paste is a viscous paste composed of high-purity (99.9%) metallic silver particles, binders, solvents, and additives—a mechanical mixture. The silver paste printing line can be arranged on the third surface 41 of the inner glass plate 40 through a printing process, or it can be arranged on the second surface 32 of the outer glass plate 30 through a printing process. It should be noted that the material and quantity of the heating element 80 can be selected according to the heating performance requirements of the information acquisition area 20. This application does not impose any limitations on this.

[0109] When the heating element 80 is a heating wire, the heating wire can also be a fine copper wire with conductive properties. It can be a fine copper wire made by forging and drawing copper wire, with a wire diameter ranging from 0.002 mm to 0.08 mm (including the endpoint values ​​of 0.002 mm and 0.08 mm). The resistance range of the fine copper wire can be from 0.5 Ω / m to 3.0 Ω / m (including the endpoint values ​​of 0.5 Ω / m and 3.0 Ω / m). The fine copper wire can be integrated onto a PET or other material film by embedding or laying, such as sandwiching a PET film with fine copper wire between the inner glass plate 40 and the outer glass plate 30 using a lamination process. In some embodiments, the heating element 80 can also be a fine tungsten wire.

[0110] A power source (not shown) is located in the vehicle 1000 and is used to provide voltage and current to the window glass 100. Depending on the actual application scenario, the power source may include a first voltage or a second voltage. In one possible implementation, the first voltage may be 12–14V (including endpoint values ​​of 12V and 14V). In another possible implementation, the second voltage may be 20–50V (including endpoint values ​​of 20V and 50V).

[0111] The structure of the vehicle window glass 100 when the power supply is a first voltage or a second voltage will be described below through two embodiments.

[0112] First embodiment: Taking the power supply as the first voltage as an example, according to the formula P=U 2 / R, R=ρL / S (where ρ is the resistivity of the material used to make the heating element, L is the length of the heating element wound into a resistor, S is the cross-sectional area of ​​the heating element wound into a resistor, R is the resistance value of the heating element, U is the voltage of the power supply, and P is the power). In this embodiment, when the voltage of the power supply remains constant, it is necessary to reduce the resistance to increase the power in the first signal transmission zone 21 and the second signal transmission zone 22, so that the heating element 80 can reach the required power in the first signal transmission zone 21 and the second signal transmission zone 22 to achieve the purpose of defrosting, defogging, and de-icing. Therefore, with the same material (ρ and S unchanged), it is necessary to reduce the length L of the heating element 80 wound into a resistor, that is, to reduce the length of the circuit formed by the heating element.

[0113] Please refer again to Figure 4, which shows a structural schematic diagram of the first embodiment of the vehicle window glass 100. To reduce the loop length formed by the heating element 80 in the first signal transmission area 21 and the second signal transmission area 22, the arrangement of the heating element 80 in the first embodiment of the vehicle window glass 100 is described in detail below using three specific embodiments.

[0114] As shown in Figure 4, Figure 4 specifically illustrates a structural schematic diagram of the first embodiment of the vehicle window glass.

[0115] In this embodiment, the first signal transmission area 21 and the second signal transmission area 22 are spaced apart along the vertical direction of the vehicle window glass 100. Both the first signal transmission area 21 and the second signal transmission area 22 face the top of the vehicle 1000, and the first signal transmission area 21 is located above the second signal transmission area 22. It should be noted that in other embodiments, the first signal transmission area 21 and the second signal transmission area 22 may be spaced apart along the horizontal direction of the vehicle window glass 100. That is, in this application, the first signal transmission area 21 and the second signal transmission area 22 are spaced apart along either the horizontal or vertical direction.

[0116] In this embodiment, a shielding area 12 is provided around the first signal transmission area 21, and the first signal transmission area 21 and the shielding area 12 do not overlap. The shape of the first signal transmission area 21 can be triangular, pentagonal, hexagonal, trapezoidal, etc. For example, the shape of the first signal transmission area 21 is approximately trapezoidal.

[0117] In this embodiment, a shielding area 12 and a main viewing area 11 are provided around the second signal transmission area 22. The second signal transmission area 22 does not overlap with the shielding area 12 and is located at the bottom edge of the shielding area 12 facing the main viewing area 11. The second signal transmission area 22 does not overlap with the main viewing area 11 and is located at the top edge of the main viewing area 11 facing the shielding area 12. The shape of the second signal transmission area 22 can be triangular, pentagonal, hexagonal, trapezoidal, etc. For example, the shape of the second signal transmission area 22 is approximately trapezoidal.

[0118] In this embodiment, the first viewing angle region 101 of the first sensor 310 is completely located within the first signal transmission region 21. The area of ​​the first viewing angle region 101 is smaller than the area of ​​the first signal transmission region 21. The edges of the first viewing angle region 101 and the edges of the first signal transmission region 21 are spaced apart. It can be understood that the first viewing angle region 101 is a closed window. In other possible embodiments, the first viewing angle region 101 completely overlaps with the first signal transmission region 21. The area of ​​the first viewing angle region 101 is equal to the area of ​​the first signal transmission region 21.

[0119] In this embodiment, the second viewing angle region 102 of the second sensor 320 can be completely located within the second signal transmission region 22. The area of ​​the second viewing angle region 102 is smaller than the area of ​​the second signal transmission region 22. The edge of the second viewing angle region 102 partially coincides with the edge of the second signal transmission region 22. It can be understood that the second viewing angle region 102 is an open window. In other possible embodiments, the second viewing angle region 102 completely coincides with the second signal transmission region 22. The area of ​​the second viewing angle region 102 is equal to the area of ​​the second signal transmission region 22.

[0120] It should be noted that in this embodiment, the distance between the first viewing area 101 and the second viewing area 102 is greater than or equal to 3mm.

[0121] In this embodiment, in order to reduce the circuit length formed by the heating element 80 while taking into account the heating control of the first signal transmission area 21 and the second signal transmission area 22, the number of heating elements 80 is two.

[0122] The heating element 80 includes a first heating element 81 and a second heating element 82. Both the first heating element 81 and the second heating element 82 are located between the inner glass plate 40 and the intermediate layer 50. Alternatively, both the first heating element 81 and the second heating element 82 are located between the outer glass plate 30 and the intermediate layer 50. Alternatively, both the first heating element 81 and the second heating element 82 are located on the intermediate layer 50. The first heating element 81 extends through the first signal transmission area 21, and the second heating element 82 extends through the second signal transmission area 22. Specifically, a portion of the first heating element 81 is located within the shielding area 12 and the main viewing area 11, and another portion of the first heating element 81 is located within the first signal transmission area 21. A portion of the second heating element 82 is located within the shielding area 12 and the main viewing area 11, and another portion of the second heating element 82 is located within the second signal transmission area 22.

[0123] In this embodiment, the vehicle window glass 100 further includes a third busbar 72. The first busbar 70 and the second busbar 71 are both electrically connected to the power supply of the vehicle 1000, and the power supply of the vehicle 1000 provides a first voltage to the vehicle window glass 100. The first busbar 70, the second busbar 71, and the third busbar 72 are all spaced apart, with the third busbar 72 located between the first busbar 70 and the second busbar 71. The first busbar 70, the second busbar 71, and the third busbar 72 are all electrically connected to the transparent conductive film 60, and the third busbar 72 is electrically connected to the first busbar 70 via a heating element 80. Specifically, one end of the first heating element 81 and the second heating element 82 are both connected to the first busbar 70, and the other end of the first heating element 81 and the second heating element 82 are both connected to the third busbar 72.

[0124] Specifically, in this embodiment, the third busbar 72 is located between the outer glass panel 30 and the inner glass panel 40, and the third busbar 72 is not located within the shielding area 12. More specifically, the third busbar 72 is located in the main viewing area 11. The third busbar 72 is laminated on the transparent conductive film 60 and electrically connected to the transparent conductive film 60. Along the vertical direction of the window glass 100, the third busbar 72 is located between the first busbar 70 and the second busbar 71, and is spaced apart from the first busbar 70 and the second busbar 71. The material of the third busbar 72 can be, but is not limited to, metallic copper sheet, conductive silver paste, etc.

[0125] Specifically, in this embodiment, the first heating element 81 includes a first segment 811, a second segment 812, and a third segment 813. The first segment 811, second segment 812, and third segment 813 are connected sequentially. The first segment 811 is located in the shielding area 12 and is used for electrical connection with the first busbar 70. The first segment 811 avoids the second heating element 82. The second segment 812 is located within the first signal transmission area 21, extending in a serpentine pattern along the vertical direction of the window glass 100 within the first signal transmission area 21. A portion of the third segment 813 extends along the connection edge between the second signal transmission area 22 and the main viewing area 11. Another portion of the third segment 813 is located in the main viewing area 11 for electrical connection with the third busbar 72.

[0126] Specifically, in this embodiment, the second heating element 82 includes a fourth segment 821, a fifth segment 822, and a sixth segment 823. The fourth segment 821, fifth segment 822, and sixth segment 823 are connected sequentially. The fourth segment 821 is located in the shielding area 12 and is used for electrical connection with the first busbar 70. The fourth segment 821 avoids the first signal transmission area 21 and the first heating element 81. The fifth segment 822 is located within the second signal transmission area 22, extending in a serpentine pattern along the vertical direction of the window glass 100 within the second signal transmission area 22. The sixth segment 823 is located within the main viewing area 11 and is used for electrical connection with the third busbar 72. In this embodiment, the extension shape of the first segment 811, the third segment 813, the fourth segment 821, and the sixth segment 823 is not limited; they can be serpentine extensions that meet the wire spacing requirements, or extensions of other shapes.

[0127] In one possible implementation, the connector 73 on the second busbar 71 is connected to the positive terminal of the power supply, and the connector 73 on the first busbar 70 is connected to the negative terminal of the power supply. Therefore, when the power supply energizes the first busbar 70 and the second busbar 71, the current flows sequentially through the connector 73 on the second busbar 71, the second busbar 71, the transparent conductive film 60, the third busbar 72, the third segment 813 of the first heating element 81, the second segment 812 of the first heating element 81, the first segment 811 of the first heating element 81, the first busbar 70, and the connector 73 on the first busbar 70, thereby forming a first circuit. The heating current flows through the first heating element 81 to heat the first signal transmission area 21. Simultaneously, the current flows sequentially through the connector 73 on the second busbar 71, the second busbar 71, the transparent conductive film 60, the third busbar 72, the sixth segment 823, the fifth segment 822, the fourth segment 821 of the second heating element 82, the first busbar 70, and the connector 73 on the first busbar 70, thus forming a second circuit. The heating current flows through the second heating element 82 to heat the second signal transmission area 22. Simultaneously, within the main viewing area 11, the current flows sequentially through the second busbar 71, the transparent conductive film 60, and the first busbar 70, thereby heating the main viewing area 11.

[0128] In another possible implementation, the connector 73 on the second busbar 71 is connected to the negative terminal of the power supply, and the connector 73 on the first busbar 70 is connected to the positive terminal of the power supply. When the power supply energizes the first busbar 70 and the second busbar 71, the current flow direction of the first circuit is opposite to that of the aforementioned first circuit, the current flow direction of the second circuit is also opposite to that of the aforementioned second circuit, and the current flow direction of the main viewing area 11 is also opposite to that of the aforementioned main viewing area 11. This application does not impose strict limitations on this.

[0129] In this embodiment, when current and voltage are supplied by a power source, the first signal transmission area 21, the second signal transmission area 22 and the main viewing area 11 can be heated simultaneously to achieve the purpose of defrosting, defogging and de-icing of the first signal transmission area 21, the second signal transmission area 22 and the main viewing area 11.

[0130] In this embodiment, a first heating element 81 is arranged in the first signal transmission region 21, so that the first heating element 81 controls the heating of the first signal transmission region 21. A second heating element 82 is arranged in the second signal transmission region 22, so that the second heating element 82 controls the heating of the second signal transmission region 22. Therefore, when the power supply is the first voltage, the heating element 80 does not need to pass through the first region 21 and the second region 22 in sequence, reducing the loop length of the heating element 80, that is, reducing the length L of the heating element 80 wound into a resistor, reducing the resistance, so that the first heating element 81 and the second heating element 82 can reach the power to raise the temperature of the first signal transmission region 21 and the second signal transmission region 22, thereby achieving the purpose of defrosting, defogging, and de-icing of the first signal transmission region 21 and the second signal transmission region 22.

[0131] In addition, by independently arranging the first heating element 81 and the second heating element 82 in the first signal transmission area 21 and the second signal transmission area 22, the arrangement of the first heating element 81 and the second heating element 82 can be adjusted according to the heating requirements, such as the wire diameter, wire spacing, and wire length of the heating element 80, thereby achieving the power density required by the first heating element 81 in the first signal transmission area 21 and the power density required by the second heating element 82 in the second signal transmission area 22.

[0132] The first heating element 81 has a high power density range. In one possible implementation, the power density of the first heating element 81 in the first signal transmission region 21 satisfies 2.0 W / dm². 2 ~15W / dm 2 (including endpoint value 2.0W / dm) 2 and 15W / dm 2This allows frost, snow, ice, etc., on the first surface 31 of the outer glass panel 30 located in the first signal transmission zone 21, and fog on the fourth surface 42 of the inner glass panel 40, to be melted and evaporated by the heat from the first heating element 81. This achieves the purpose of actively defrosting, defogging, and de-icing the vehicle window glass 100 in the first signal transmission zone 21. In another possible implementation, to further shorten the defrosting, defogging, and de-icing time, the power density of the first heating element 81 in the first signal transmission zone 21 satisfies 8.0 W / dm². 2 ~15W / dm 2 (including endpoint value 8.0W / dm) 2 and 15W / dm 2 In another possible implementation, the power density of the first heating element 81 in the first signal transmission region 21 satisfies 9.0 W / dm². 2 ~11W / dm 2 (including endpoint value 9.0W / dm) 2 and 11W / dm 2 This will further shorten the time for defrosting, defogging, and de-icing.

[0133] The second heating element 82 has a high power density range. In one possible implementation, the power density of the second heating element 82 in the second signal transmission region 22 satisfies 2.0 W / dm². 2 ~15W / dm 2 (including endpoint value 2.0W / dm) 2 and 15W / dm 2 This allows frost, snow, ice, etc., on the first surface 31 of the outer glass panel 30 located in the second signal transmission zone 22, and fog on the fourth surface 42 of the inner glass panel 40, to be melted and evaporated by the heat from the second heating element 82. This achieves the purpose of actively defrosting, defogging, and de-icing the vehicle window glass 100 in the second signal transmission zone 22. In another possible implementation, to further shorten the defrosting, defogging, and de-icing time, the power density of the second heating element 82 in the second signal transmission zone 22 meets the requirement of 8.0 W / dm². 2 ~15W / dm 2 (including endpoint value 8.0W / dm) 2 and 15W / dm 2 In another possible implementation, the power density of the second heating element 82 in the second signal transmission region 22 satisfies 9.0 W / dm². 2 ~11W / dm 2 (including endpoint value 9.0W / dm) 2 and 11W / dm 2 This will further shorten the time for defrosting, defogging, and de-icing.

[0134] It should be noted that, considering the influence of the wire spacing of the first heating element 81 and the second heating element 82 on the heating effect of the first signal transmission area 21 and the second signal transmission area 22, respectively, and considering the influence of the first heating element 81 and the second heating element 82 on the signal transmission of the first sensor 310 and the second sensor 320, respectively, the wire diameter of both the first heating element 81 and the second heating element 82 is less than or equal to 0.18 mm. Preferably, the wire diameter of both the first heating element 81 and the second heating element 82 is less than or equal to 0.12 mm. The wire spacing of both the first heating element 81 and the second heating element 82 must be greater than or equal to 20 mm. Wherein, the wire spacing of the first heating element 81 is the winding interval distance of the first heating element 81. The wire spacing of the second heating element 82 is the winding interval distance of the second heating element 82.

[0135] Please refer to Figure 5, which is a structural schematic diagram of the second embodiment of the first embodiment of the vehicle window glass 100 shown in Figure 1.

[0136] Unlike the first embodiment described above, in this embodiment, the window glass 100 does not include the third busbar 72, the opposite ends of the length direction of the first heating element 81 are electrically connected to the first busbar 70, and the opposite ends of the length direction of the second heating element 82 are also electrically connected to the first busbar 70.

[0137] Specifically, the first busbar 70 includes a first sub-segment 701 and a second sub-segment 702, which are spaced apart and insulated from each other, and the first sub-segment 701, the second sub-segment 702, and the second busbar 71 are also spaced apart. The first sub-segment 701 is electrically connected to the second sub-segment 702 via a heating element 80. In this embodiment, both the first sub-segment 701 and the second sub-segment 702 are connected to the power supply of the vehicle 1000, and the power supply of the vehicle 1000 provides a first voltage to the window glass 100. Specifically, one end of the first heating element 81 and the second heating element 82 are both connected to the first sub-segment 701, and the other end of the first heating element 81 and the second heating element 82 are both connected to the second sub-segment 702. That is, the first segment 811 of the first heating element 81 and the fourth segment 821 of the second heating element 82 are both connected to the first sub-segment 701. The third segment 813 of the first heating element 81 and the sixth segment 823 of the second heating element 82 are both connected to the second sub-segment 702.

[0138] In one possible implementation, connectors 73 are respectively provided on the first sub-segment 701 and the second sub-segment 702. The connector 73 on the first sub-segment 701 is connected to the positive terminal of the power supply, and the connector 73 on the second sub-segment 702 is connected to the negative terminal of the power supply. Therefore, when the power supply is energized to the first bus 70, the current will flow sequentially through the connector 73 on the first sub-segment 701 of the first bus 70, the first sub-segment 701, the first segment 811 of the first heating element 81, the second segment 812 of the first heating element 81, the third segment 813 of the first heating element 81, the second sub-segment 702, and the connector 73 on the second sub-segment 702, thereby forming a third circuit. The heating current flows through the first heating element 81 to heat the first signal transmission area 21. Simultaneously, the current flows sequentially through the connector 73 on the first sub-segment 701 of the first busbar 70, the first sub-segment 701, the fourth segment 821 of the second heating element 82, the fifth segment 822 of the second heating element 82, the sixth segment 823 of the second heating element 82, the second sub-segment 702, and the connector 73 on the second sub-segment 702, thereby forming a fourth circuit. The heating current flows through the second heating element 82 to heat the second signal transmission area 22.

[0139] In another possible implementation, the connector 73 of the first sub-segment 701 is connected to the negative terminal of the power supply, the connector 73 of the second sub-segment 702 is connected to the positive terminal of the power supply, the current flow direction of the third circuit is opposite to that of the aforementioned third circuit, and the current flow direction of the fourth circuit is also opposite to that of the aforementioned fourth circuit. This implementation does not impose strict limitations on this.

[0140] In this embodiment, the first busbar 70 is broken into a second sub-segment 702 and a first sub-segment 701 to avoid short circuits between the first heating element 81 and the second heating element 82. By energizing the first busbar 70, current flows simultaneously through the first heating element 81 and the second heating element 82, allowing simultaneous heating of the first signal transmission area 21 and the second signal transmission area 22, thus meeting the driver's needs for defogging, snow removal, and de-icing in the first and second signal transmission areas 21 and 22. Furthermore, by independently arranging the first heating element 81 and the second heating element 82 in the first and second signal transmission areas 21 and 22 respectively, the arrangement of the first heating element 81 and the second heating element 82 can be adjusted according to heating requirements, such as the wire diameter, wire spacing, and wire length of the heating element 80, thereby achieving the required power density of the first heating element 81 in the first signal transmission area 21 and the required power density of the second heating element 82 in the second signal transmission area 22.

[0141] It should be noted that when the first busbar 70 and the second busbar 71 are energized, the transparent conductive film 60 heats the main viewing area 11, thereby separating the heating of the main viewing area 11 from the heating of the first signal transmission area 21 and the second signal transmission area 22, further meeting the customer's heating requirements in the actual application of the vehicle window glass 100.

[0142] It should be noted that the contents that are the same as those in the first embodiment described above will not be repeated here.

[0143] Please refer to Figure 6, which is a structural schematic diagram of the third embodiment of the first embodiment of the vehicle window glass shown in Figure 1.

[0144] Unlike the second embodiment of the first embodiment described above, in this embodiment, along the vertical direction of the window glass 100, both the first signal transmission area 21 and the second signal transmission area 22 are located below the shielding area 12 and are spaced apart from it. That is, the window glass 100 also includes an information acquisition area 20 for signal transmission from the first sensor 310 and the second sensor 320, and both the first signal transmission area 21 and the second signal transmission area 22 are located within the information acquisition area 20, while the transparent conductive film 60 avoids the information acquisition area 20. In this embodiment, the first signal transmission area 21 and the second signal transmission area 22 are spaced apart along the horizontal direction of the window glass 100. For example, the first signal transmission area 21 is located to the left of the second signal transmission area 22.

[0145] In this embodiment, a main viewing area 11 is provided around both the first signal transmission area 21 and the second signal transmission area 22, and neither overlaps with the main viewing area 11. The first viewing angle area 101 of the first sensor 310 completely overlaps with the first signal transmission area 21. The second viewing angle area 102 of the second sensor 320 completely overlaps with the second signal transmission area 22, increasing the utilization rate of the area on the vehicle window glass 100 and helping to better realize the heating of the main viewing area 11 and the information acquisition area 20.

[0146] In this embodiment, the first busbar 70 further includes a third sub-segment 703. The third sub-segment 703 is disposed between the first sub-segment 701 and the second sub-segment 702, and is spaced apart from and insulated from the first sub-segment 701 and the second sub-segment 702.

[0147] In one possible implementation, the third sub-segment 703 is provided with a connector (not shown). The first sub-segment 701 and the third sub-segment 703 are electrically connected to the power supply via the connector. The first segment 811 of the first heating element 81 is connected to the first sub-segment 701, and the third segment 813 is connected to the third sub-segment 703. The connector 73 located in the first sub-segment 701 is connected to the positive terminal of the power supply, and the connector located in the third sub-segment 703 is connected to the negative terminal of the power supply. Therefore, when the power supply energizes the first busbar 70, the current flows sequentially through the connector 73 located in the first sub-segment 701, the first sub-segment 701, the first segment 811 of the first heating element 81, the second segment 812 of the first heating element 81, the third segment 813 of the first heating element 81, the third sub-segment 703, and the connector located in the third sub-segment 703, thereby forming a fifth circuit. The heating current flows through the first heating element 81 to heat the first signal transmission area 21.

[0148] In another possible implementation, the third sub-segment 703 is provided with a connector (not shown). The second sub-segment 702 and the third sub-segment 703 are electrically connected to a power source via the connector. The fourth segment 821 of the second heating element 82 is connected to the third sub-segment 703, and the sixth segment 823 is connected to the second sub-segment 702. The connector 73 located in the second sub-segment 702 is connected to the positive terminal of the power source, and the connector located in the third sub-segment 703 is connected to the negative terminal of the power source. Current flows sequentially through the connector 73 of the second sub-segment 702, the second sub-segment 702, the sixth segment 823 of the second heating element 82, the fifth segment 822 of the second heating element 82, the fourth segment 821 of the second heating element 82, the third sub-segment 703, and the connector located in the third sub-segment 703, thereby forming a sixth circuit. The heating current flows through the second heating element 82 to heat the second signal transmission area 22.

[0149] In another possible implementation, the connector 73 located in the first sub-segment 701 is connected to the negative terminal of the power supply, the connector 73 located in the second sub-segment 702 is connected to the negative terminal of the power supply, and the connector located in the third sub-segment 703 is connected to the positive terminal of the power supply. The current flow direction of the fifth circuit is opposite to that of the aforementioned fifth circuit, and the current flow direction of the sixth circuit is also opposite to that of the aforementioned sixth circuit. This implementation does not impose strict limitations on this.

[0150] In this embodiment, the first busbar 70 is divided into three sections to prevent short circuits between the first heating element 81 and the second heating element 82. By energizing the first busbar 70, the first heating element 81 and the second heating element 82 can be controlled independently. This allows the first heating element 81 to heat the first signal transmission area 21, and the second heating element 82 to heat the second signal transmission area 22. This not only meets the driver's needs for defogging, snow removal, and de-icing in either the first area 21 or the second area 22, but also achieves energy conservation.

[0151] It should be noted that when the first busbar 70 and the second busbar 71 are energized, the transparent conductive film 60 heats the main viewing area 11, thereby separating the heating of the main viewing area 11, the heating of the first signal transmission area 21 and the heating of the second signal transmission area 22, further meeting the customer's heating needs in the actual application of the vehicle window glass 100.

[0152] In another possible implementation, both the first sub-segment 701 and the second sub-segment 702 are connected to the power supply of the vehicle 1000. The power supply of the vehicle 1000 provides a first voltage to the window glass 100. One end of the first heating element 81 and the second heating element 82 are both connected to the third sub-segment 703, the other end of the first heating element 81 is connected to the first sub-segment 701, and the other end of the second heating element 82 is connected to the second sub-segment 702. That is, the third sub-segment 703 does not have a connector for connecting to the power supply, and current flows through both the first heating element 81 and the second heating element 82 simultaneously to control the heating of both the first signal transmission area 21 and the second signal transmission area 22. It should be noted that the contents that are the same as those in the second implementation of the first embodiment described above will not be repeated here.

[0153] Second embodiment: Taking the power supply as the second voltage as an example, according to the formula P=U 2 / R, R=ρL / S. In this embodiment, when the power supply voltage remains constant, it is necessary to increase the resistance to reduce the power in the first signal transmission area 21 and the second signal transmission area 22. This is to prevent excessive voltage from causing excessive power in the first signal transmission area 21 and the second signal transmission area 22, which would generate local hot spots, while ensuring the heating of the first signal transmission area 21 and the second signal transmission area 22. This would prevent the local temperature of the first signal transmission area 21 and the second signal transmission area 22 from becoming too high and causing the car window glass 100 to shatter. Therefore, with the same material (ρ and S unchanged), it is necessary to increase the length L of the heating element 80 wound into a resistor, that is, to increase the length of the circuit formed by the heating element 80.

[0154] Please refer to Figure 7, which is a structural schematic diagram of the second embodiment of the vehicle window glass shown in Figure 1. Unlike the first embodiment described above, in this embodiment, to increase the circuit length of the heating element 80 of the window glass 100, the number of heating elements 80 is one. One heating element 80 passes through the first signal transmission area 21 and the second signal transmission area 22 simultaneously as much as possible to increase the effective utilization rate of the heating element 80, reduce the power of the heating element 80, and prevent excessive power from causing localized hot spots within the information acquisition area 20. Specifically, the heating element 80 includes at least one heating wire, which extends through the first signal transmission area 21 and the second signal transmission area 22.

[0155] It should be noted that the contents that are the same as those in the first embodiment described above will not be repeated. The following will provide a detailed description of the arrangement of the heating element 80 in the second embodiment of the vehicle window glass 100 using five specific implementation methods.

[0156] Please refer to Figure 7 again, which shows a schematic diagram of the structure of the first embodiment of the second embodiment of the vehicle window glass.

[0157] In this embodiment, one end of the heating element 80 along its length is connected to the first busbar 70, and the other end of the heating element 80 along its length is connected to the third busbar 72.

[0158] Specifically, the heating element 80 includes a seventh segment 83, an eighth segment 84, and a ninth segment 85, which are connected sequentially. The seventh segment 83 is located in the shielding area 12 and is electrically connected to the first busbar 70. The eighth segment 84 is located at least within the first signal transmission area 21 and the second signal transmission area 22. Along the vertical direction of the window glass 100, the eighth segment 84 extends in a serpentine pattern within the first signal transmission area 21 and the second signal transmission area 22. The ninth segment 85 is located in the main viewing area 11 and is electrically connected to the third busbar 72. In this embodiment, the extension shape of the seventh segment 83 and the ninth segment 85 is not limited; they can be extensions of any shape that meets the wire pitch requirement. The wire pitch of the heating element 80 is the interval distance between the windings of the heating element 80.

[0159] In one possible implementation, connector 73 on the second busbar 71 is connected to the positive terminal of the power supply, and connector 73 on the first busbar 70 is connected to the negative terminal of the power supply. Therefore, current flows sequentially through connector 73 on the second busbar 71, the second busbar 71, the transparent conductive film 60, the third busbar 72, the ninth segment 85, the eighth segment 84, and the seventh segment 83 of the heating element 80, the first busbar 70, and connector 73 on the first busbar 70, thus forming a seventh circuit. The heating current flows through the heating element 80 to heat the first signal transmission area 21 and the second signal transmission area 22. In this implementation, the heating element 80 is simultaneously arranged within the first signal transmission area 21 and the second signal transmission area 22. By providing current and voltage to the first busbar 70 and the second busbar 71 through the power supply, the heating element 80 can heat the first signal transmission area 21 and the second signal transmission area 22. Simultaneously, the transparent conductive film 60 also heats the main viewing area 11.

[0160] In another possible implementation, the connectors 73 on the first busbar 70 and the second busbar 71 are connected to the positive and negative terminals of the power supply, respectively, and the current flow direction of the seventh circuit is opposite to that of the aforementioned seventh circuit. This implementation does not impose strict limitations on this.

[0161] It should be noted that, considering the influence of the wire spacing of the heating element 80 on the heating effect of the first signal transmission area 21 and the second signal transmission area 22, and considering the influence of the heating element 80 on the performance of the first sensor 310 and the second sensor 320, the wire diameter of the heating element 80 is less than or equal to 0.18 mm, preferably less than or equal to 0.12 mm. The wire spacing of the heating element 80 is greater than or equal to 20 mm.

[0162] Please refer to Figure 8, which is a structural schematic diagram of the second embodiment of the second embodiment of the vehicle window glass shown in Figure 1.

[0163] Unlike the first embodiment of the second embodiment described above, in this embodiment, the window glass 100 does not include the third busbar 72. The opposite ends of the heating element 80 along its length are both connected to the first busbar 70.

[0164] The first busbar 70 includes a first sub-segment 701 and a second sub-segment 702. The first sub-segment 701 and the second sub-segment 702 are spaced apart and insulated from each other. The seventh segment 83 of the heating element 80 is connected to the first sub-segment 701, and the ninth segment 85 of the heating element 80 is connected to the second sub-segment 702.

[0165] In one possible implementation, the connector 73 located on the first sub-segment 701 is connected to the positive terminal of the power supply, and the connector 73 located on the second sub-segment 702 is connected to the negative terminal of the power supply. Therefore, when the power supply is energized to the first busbar 70, the current will flow sequentially through the connector 73 located on the first sub-segment 701 of the first busbar 70, the first sub-segment 701, the seventh segment 83 of the heating element 80, the eighth segment 84 of the heating element 80, the ninth segment 85 of the heating element 80, the second sub-segment 702, and the connector 73 located on the second sub-segment 702, thereby forming an eighth circuit. The heating current flows through the heating element 80 to heat the first signal transmission area 21 and the second signal transmission area 22.

[0166] In another possible implementation, the connector 73 of the first sub-segment 701 is connected to the negative terminal of the power supply, and the connector 73 of the second sub-segment 702 is connected to the positive terminal of the power supply. The current flow direction of the eighth circuit is opposite to that of the aforementioned eighth circuit. This implementation does not impose strict limitations on this.

[0167] It should be noted that in this embodiment, the first busbar 70 is broken into two sections to avoid short circuits in the heating element 80. When the first busbar 70 is energized, the heating element 80 can simultaneously control the heating of the first signal transmission area 21 and the second signal transmission area 22. When the power supply is also energizing the second busbar 71, the transparent conductive film 60 heats the main viewing area 11, thereby separating the heating of the main viewing area 11 from the heating of the first signal transmission area 21 and the second signal transmission area 22 to meet different practical application needs of customers. It should be noted that the contents that are the same as those in the first embodiment of the second embodiment described above will not be repeated.

[0168] Please refer to Figure 9, which is a structural schematic diagram of the third embodiment of the second embodiment of the vehicle window glass shown in Figure 1.

[0169] In this embodiment, the vehicle window glass 100 further includes an information acquisition area 20 for signal transmission from the first sensor 310 and the second sensor 320, and both the first signal transmission area 21 and the second signal transmission area 22 are located within the information acquisition area 20, while the transparent conductive film 60 avoids the information acquisition area 20. Specifically, unlike the second embodiment described above, in this embodiment, along the vertical direction of the vehicle window glass 100, both the first signal transmission area 21 and the second signal transmission area 22 are located below the shielding area 12 and are spaced apart from it. The first signal transmission area 21 and the second signal transmission area 22 are spaced apart along the horizontal direction of the vehicle window glass 100. A main viewing area 11 is provided around both the first signal transmission area 21 and the second signal transmission area 22, and neither overlaps with the main viewing area 11. For example, the first signal transmission area 21 is located to the left of the second signal transmission area 22.

[0170] In this embodiment, the first viewing area 101 of the first sensor 310 completely overlaps with the first signal transmission area 21. The second viewing area 102 of the second sensor 320 completely overlaps with the second signal transmission area 22, which increases the utilization rate of the area on the window glass 100 and helps to better achieve the heating of the main viewing area 11, the first signal transmission area 21 and the second signal transmission area 22.

[0171] Please refer to Figure 10, which is a structural schematic diagram of the fourth embodiment of the second embodiment of the vehicle window glass shown in Figure 1. It should be noted that the dashed lines in Figure 10 not only indicate the boundary between the first viewing angle region 101 and the second viewing angle region 102, but also the boundary between the first signal transmission area 21 and the second signal transmission area 22.

[0172] In this embodiment, the vehicle window glass 100 further includes an information acquisition area 20 for signal transmission from the first sensor 310 and the second sensor 320. Both the first signal transmission area 21 and the second signal transmission area 22 are located within the information acquisition area 20, and the transparent conductive film 60 avoids the information acquisition area 20. Specifically, unlike the second embodiment described above, in this embodiment, the first signal transmission area 21 and the second signal transmission area 22 are connected along the vertical direction of the vehicle window glass 100. The first signal transmission area 21 is located above the second signal transmission area 22 and near the top of the vehicle 1000. The first viewing angle area 101 is completely disposed within the first signal transmission area 21, and the area of ​​the first viewing angle area 101 is smaller than the area of ​​the first signal transmission area 21. The second viewing angle area 102 is completely disposed within the second signal transmission area 22. The area of ​​the second viewing angle area 102 is smaller than the area of ​​the second signal transmission area 22. The first viewing angle area 101 and the second viewing angle area 102 are spaced apart along the vertical direction of the vehicle window glass 100.

[0173] In other possible implementations, the first viewing angle region 101 may completely overlap with the first signal transmission region 21, and the area of ​​the first viewing angle region 101 is equal to the area of ​​the first signal transmission region 21. The second viewing angle region 102 may completely overlap with the second signal transmission region 22, and the area of ​​the second viewing angle region 102 is equal to the area of ​​the second signal transmission region 22. It can be understood that the sum of the areas of the first viewing angle region 101 and the second viewing angle region 102 is less than or equal to the sum of the areas of the first signal transmission region 21 and the second signal transmission region 22, so as to ensure the overall aesthetics of the vehicle window glass 100. The contents of this implementation that are the same as those in the second implementation of the second embodiment described above will not be repeated.

[0174] Please refer to Figure 11, which is a structural schematic diagram of the fifth embodiment of the second embodiment of the vehicle window glass shown in Figure 1.

[0175] Unlike the fourth embodiment of the second embodiment described above, in this embodiment, when the second sensor 320 is a lidar, considering the angle of the window glass 100 when mounted on the vehicle body 200, part of the eighth segment 84 is located within the first signal transmission area 21 and extends in a serpentine shape along the vertical direction of the window glass 100. Another part of the eighth segment 84 is located within the second signal transmission area 22 and extends in a serpentine shape along the horizontal direction of the window glass 100. This reduces the influence of the wire diameter of the heating element 80 on the second sensor 320 when the heating element 80 extends in a serpentine shape in the vertical direction, and reduces the physical obstruction of the heating element 80 on the transmission and / or reception of signals from the second sensor 320 to the second signal transmission area 22, making it easier for the second sensor 320 to obtain complete image information.

[0176] It should be noted that the smaller the area occupied by the heating element 80 in the second signal transmission area 22, the smaller the influence of the heating element 80 on the second sensor 320. The contents that are the same as those in the fourth embodiment of the second embodiment described above will not be repeated.

[0177] Please refer to Figure 12, which is a line graph showing the influence of heating elements 80 with different wire diameters and wire spacings on the detection accuracy of lidar as a function of the radar channel.

[0178] As shown in the figure, when the LiDAR channel is 64.00, and the wire diameter of the heating element 80 is 0.12 mm with a wire spacing of 20 mm (i.e., curve A1 in Figure 12), the corresponding Probability of Detection (POD) of the LiDAR is approximately 97%. When the wire diameter of the heating element 80 is 0.12 mm with a wire spacing of 15 mm (i.e., curve A2 in Figure 12), the corresponding detection accuracy of the LiDAR is approximately 87%. Therefore, it can be concluded that the wire spacing of the heating element 80 affects the detection accuracy of the LiDAR.

[0179] Comparing curve A1 in Figure 12, when the wire diameter of the heating element 80 is 0.18 mm and the wire spacing is 20 mm (i.e., curve C1 in Figure 12), the detection accuracy of the lidar is approximately 96%. Therefore, it can be seen that the wire diameter of the heating element 80 has little impact on the detection accuracy of the lidar, while the wire spacing of the heating element 80 has a greater impact on the detection accuracy of the lidar.

[0180] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
