Description

Technical Field

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

[0002] In order to avoid the large temperature difference between the inside and outside of the vehicle, which may cause water mist or frost to form on the window glass, a transparent conductive film is usually set on the window glass. By energizing the transparent conductive film, the transparent conductive film is heated under the action of the current, thereby achieving the purpose of defog, defrost, and de-icing the window glass. In addition, sensor components are generally installed inside the vehicle, and the sensor components may include sensors (such as cameras) to assist the vehicle's automatic driving mode. The window glass is provided with an information collection area for allowing the signal of the sensor of the sensor component to pass through.

[0003] In order to ensure that the transparent conductive film does not block the signal of the sensor component, the transparent conductive film in the information collection area is usually removed. However, this will cause the information collection area to form water mist, frost or ice when the temperature difference between the inside and outside of the vehicle is too large, which will seriously hinder the sensor from obtaining accurate signals through the information collection area on the window glass. Therefore, a defogger and defrost structure is generally set in the information collection area.

[0080] In the present application, both the first signal transmission area 21 and the second signal transmission area 22 may be disposed on a side of the vehicle window glass 100 close to the top of the vehicle 1000 .

[0081] Please also read Figure 2 and Figure 3 , Figure 2 for Figure 1 A schematic partial cutaway view of a window assembly of a vehicle shown in FIG. Figure 3 for Figure 1 A schematic diagram of the partial structure of the vehicle window glass is shown.

[0082] The vehicle window glass 100 described in the present application is a laminated glass structure. The vehicle window glass 100 includes an outer glass plate 30, an inner glass plate 40 and an intermediate layer 50, wherein the intermediate layer 50 is bonded between the outer glass plate 30 and the inner glass plate 40, and the heating element 80 is fixed between the outer glass plate 30 and the sensor assembly 300. Along the thickness direction of the vehicle window glass 100, the outer glass plate 30, the intermediate layer 50 and the inner glass plate 40 are sequentially stacked and connected. When the vehicle window glass 100 is installed on the vehicle body 200, the outer glass plate 30 faces the outside of the vehicle 1000, and the inner glass plate 40 faces the inside of the vehicle 1000.

[0083] In this embodiment, the vehicle window glass 100 is in a curved shape. The outer glass plate 30 and the inner glass plate 40 are both subjected to a high temperature bending molding process of at least 500°C. In other embodiments, the vehicle window glass 100 may also be in a straight plate shape. The shape of the vehicle window glass 100 is not limited to the shape described above, and it may be any shape that meets the use requirements of the vehicle 1000. This embodiment does not impose strict restrictions on the shape of the vehicle window glass 100.

[0084] The outer glass plate 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 in the thickness direction of the outer glass plate 30. When the vehicle window glass 100 is mounted on the vehicle body 200, the first surface 31 of the outer glass plate 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 plate 30 faces the intermediate layer 50.

[0085] The thickness of the outer glass plate 30 may be 1.6 mm to 5.0 mm. For example, the thickness of the outer glass plate 30 may 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 implementation, the thickness of the outer glass plate 30 is 1.8 mm. In another possible implementation, the thickness of the outer glass plate 30 is 2.1 mm.

[0086] The material of the outer glass plate 30 includes, but is not limited to, soda-lime glass or aluminosilicate glass. The outer glass plate 30 may be white glass, ultra-white glass, ordinary green glass, solar green glass, etc. In this embodiment, since the sensor assembly 300 includes a laser radar, the signal emitted by the laser radar needs to pass through the outer glass plate 30. Therefore, the outer glass plate 30 may be ordinary white glass with a transmittance of 75% to 85% for visible light with a wavelength of 800nm ​​to 1600nm. Preferably, the outer glass plate 30 may be ultra-white glass with a transmittance of 85% to 95% for infrared light with a wavelength of 800nm ​​to 2100nm.

[0087] The inner glass plate 40 includes a third surface 41 and a fourth surface 42. The third surface 41 and the fourth surface 42 are disposed opposite to each other in the thickness direction of the inner glass plate 40. When the vehicle window glass 100 is mounted on the vehicle body 200, the third surface 41 of the inner glass plate 40 faces the intermediate layer 50. The fourth surface 42 of the inner glass plate 40 faces the interior of the vehicle 1000. The fourth surface 42 serves as the inner surface of the vehicle window glass 100.

[0088] The thickness of the inner glass plate 40 may be 0.7 mm to 5.0 mm. For example, the thickness of the inner glass plate 40 may 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 implementation, the thickness of the inner glass plate 40 is 1.8 mm. In another possible implementation, the thickness of the outer glass plate 30 is 2.1 mm.

[0089] The material of the inner glass plate 40 includes, but is not limited to, soda-lime glass or aluminosilicate glass. The inner glass plate 40 may be white glass, ultra-white glass, ordinary green glass, solar green glass, etc. In this embodiment, since the sensor assembly 300 includes a laser radar, the signal emitted by the laser radar needs to pass through the inner glass plate 40. Therefore, the inner glass plate 40 may be ordinary white glass with a transmittance of 75% to 85% for visible light with a wavelength of 800nm ​​to 1600nm. Preferably, the inner glass plate 40 may be ultra-white glass with a transmittance of 85% to 95% for infrared light with a wavelength of 800nm ​​to 2100nm.

[0090] The intermediate layer 50 is connected between 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.

[0091] In this embodiment, the middle layer 50 can be a single-layer structure or a multi-layer structure. The middle layer 50 can be colorless or partially colored. The middle layer 50 can be a thermoplastic middle layer 50. The material of the middle layer 50 can be polycarbonate (PC), polyvinyl chloride (PVC), polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyacrylate (PA), polymethyl methacrylate (PMMA), polyurethane (PUR), ionic polymer membrane (Sentry Glas Plus, SGP) and other materials. This application does not specifically limit the layer structure and material of the middle layer 50.

[0092] In one possible embodiment, an infrared absorber is added to the intermediate layer 50, so that the intermediate layer 50 has the function of absorbing heat and absorbing light. In another possible embodiment, the intermediate layer 50 may include at least two layers, one of which contains a higher content of plasticizer to make the window glass 100 have better sound insulation performance; the other layer is wedge-shaped so that the window glass 100 can be used for HUD function. In another possible embodiment, the intermediate layer 50 is partially colored to serve as a shielding layer to shield and protect the internal parts of the vehicle 1000 or block sunlight. For example, the intermediate layer 50 is provided with a tinted area at the top of the corresponding window glass 100, that is, the tinted area corresponding to the shielding area 12 can be spliced ​​with the uncolored transparent area of ​​the intermediate layer 50. The tinted area can reduce the interference of sunlight to the human eye. For another example, the intermediate layer 50 is provided with a tinted area at the bottom of the corresponding window glass 100, and the tinted area can be spliced ​​with the uncolored transparent area of ​​the intermediate layer 50. The tinted area is used to shield and protect the internal parts of the vehicle 1000. For another example, the middle layer 50 has two tinted areas at the top and bottom of the corresponding window glass 100 , respectively. The two tinted areas are located on opposite sides of the untinted transparent area in the middle of the middle layer 50 in the vertical direction, and are spliced ​​with the untinted transparent area in the middle of the middle layer 50 .

[0093] like Figures 3 to 11As shown, the vehicle window glass 100 described in the present 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 for the occupants to observe the outside environment through the main viewing area 11, and for light transmission inside and outside the vehicle 1000. The main viewing area 11 is a window of the vehicle 1000. In some embodiments, the main viewing area 11 can 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.

[0094] The shielding area 12 is used for setting a shielding layer or a colored intermediate layer 50 to prevent visible light from passing through the vehicle window glass 100. In the present embodiment, the shape of the main viewing area 11 matches the shape of the vehicle window glass 100. The shielding area 12 is roughly in the shape of a ring frame. The outer edge of the shielding area 12 is the outer edge of the vehicle 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 part of the peripheral side of the main viewing area 11 and part of the peripheral side of the first signal transmission area 21 and the second signal transmission area 22.

[0095] like Figures 3 to 11 As shown, the vehicle window glass 100 further includes a transparent conductive film 60. The transparent conductive film 60 is disposed in the main viewing area 11 of the vehicle window glass 100, and completely avoids the first signal transmission area 21 and the second signal transmission area 22 of the vehicle window glass 100, and the transparent conductive film 60 is located between the outer glass plate 30 and the inner glass plate 40. The transparent conductive film 60 can be laminated on the outer glass plate 30 or the inner glass plate 40. Specifically, the transparent conductive film 60 can cover the second surface 32 of the outer glass plate 30 located in the main viewing area 11, and can also cover the third surface 41 of the inner glass plate 40 located in the main viewing area 11. This application does not limit this.

[0096] The transparent conductive film 60 can be directly deposited on the outer glass plate 30 or the inner glass plate 40 by a method other than 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 deposition.

[0097] 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 plate 30 is preferably made of white glass or ultra-white glass to increase the reflection of solar energy by the window glass 100, reduce the total energy transmittance of solar energy, and play a heat insulation role. At the same time, if a bus bar and a power supply are added to the transparent conductive film 60, the transparent conductive film 60 has a conductive property. By energizing the transparent conductive film 60 to heat the transparent conductive film 60, the purpose of defogging, defrosting, and deicing the window glass 100 is achieved.

[0098] The transparent conductive film 60 can withstand high-temperature heat treatment, for example, it can be subjected to heat treatment such as bending or tempering. The transparent conductive film 60 may include a metal layer, a metal alloy layer or a metal oxide layer. The material of the metal layer may be selected from materials such as gold (Au), silver (Ag), copper (Cu), aluminum (Al) or molybdenum (Mo), and the material of the metal oxide layer may be selected from 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. Exemplarily, when the transparent conductive film 60 includes a silver layer or a silver alloy layer, the silver layer or the silver alloy layer is located between at least two dielectric layers, and the dielectric layer contains zinc oxide (ZnO), tin oxide (SnO2), indium oxide (In2O3), titanium oxide (TiO x ), silicon oxide (SiO2), aluminum oxide (Al2O3), silicon nitride (Si3N4), silicon carbide (SiC), aluminum nitride (AlN) or at least one of a titanium metal layer.

[0099] The vehicle window glass 100 also includes a plurality of busbars. In the present application, the busbars include a first busbar 70 and a second busbar 71 that are spaced apart, and the first busbar 70 and the second busbar 71 are both electrically connected to the transparent conductive film 60. In the present application, the first busbar 70 and the second busbar 71 are spaced apart along two opposite sides of the transparent conductive film 60. Specifically, the first busbar 70 and the second busbar 71 are respectively located on opposite sides of the vehicle window glass 100 in the vertical direction, and the first busbar 70 and the second busbar 71 are both located in the shielding area 12, so that the first busbar 70 and the second busbar 71 are not visible to the human eye from the outside of the vehicle 1000, thereby improving the overall aesthetics of the vehicle window glass 100. In the present application, the first busbar 70 and the second busbar 71 are both located between the outer glass plate 30 and the inner glass plate 40. It should be noted that the first busbar 70 and the second busbar 71 are both laminated on the transparent conductive film 60.

[0100] The first busbar 70 is located on one side of the shielding area 12 close to the top of the vehicle 1000. The distance between the first busbar 70 and the upper edge of the vehicle window glass 100 (i.e., the outer edge of the vehicle window glass 100 close to the edge of the top of the vehicle 1000) is 6 to 30 mm. For example, the distance between the first busbar 70 and the upper edge of the vehicle window glass 100 can be, but 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 not limited to, metal foil, conductive silver paste, etc.

[0101] The second busbar 71 is located on one side of the shielding area 12 close to the bottom of the vehicle 1000. The distance between the second busbar 71 and the lower edge of the vehicle window glass 100 (i.e., the outer edge of the vehicle window glass 100 close to the side edge of the bottom of the vehicle 1000) is 6 to 30 mm. For example, the distance between the second busbar 71 and the lower edge of the vehicle window glass 100 can be, but 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 not limited to, metal foil, conductive silver paste, etc.

[0102] The vehicle window glass 100 also includes a plurality of joints 73. The plurality of joints 73 are provided on the first busbar 70 and the second busbar 71. The joint 73 is used to be electrically connected to the positive or negative pole of the power supply of the vehicle. Exemplarily, two joints 73 are provided on the first busbar 70. The two joints 73 on the first busbar 70 are electrically connected to the positive and negative poles of the power supply, respectively. The two joints 73 on the first busbar 70 may also be both electrically connected to the positive pole, or both electrically connected to the negative pole. Two joints 73 are provided on the second busbar 71. The two joints 73 on the second busbar 71 are electrically connected to the positive and negative poles of the power supply, respectively. The two joints 73 on the second busbar 71 may also be both electrically connected to the positive pole, or both electrically connected to the negative pole. 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 can be understood that the power supply can energize the first busbar 70 and the second busbar 71, and the current will flow through the transparent conductive film 60 between the first busbar 70 and the second busbar 71, so that the transparent conductive film 60 will heat up and generate heat under the action of the current, so as to heat the main viewing area 11 and achieve the purpose of defrosting, defogging, and deicing the main viewing area 11.

[0103] In the present 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, so that the heating element 80 generates heat and generates heat under the action of the current, so as to heat the first signal transmission area 21 and the second signal transmission area 22, and achieve the purpose of defrosting, defogging, deicing, etc. of the first signal transmission area 21 and the second signal transmission area 22.

[0104] In some embodiments, the vehicle window glass 100 further includes a shielding layer 90. The shielding layer 90 is laminated on the periphery of the second surface 32 of the outer glass plate 30 or the third surface 41 of the inner glass plate 40. The shielding layer 90 covers the shielding area 12 of the vehicle 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 direction and the length direction are respectively equal to the dimensions of the shielding area 12 in the width direction and the length direction). 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 direction and the length direction are respectively smaller than the dimensions of the shielding area 12 in the width direction and the length direction).

[0105] The material of the shielding layer 90 is usually 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 and improve the overall aesthetics from the outside of the vehicle 1000. On the other hand, the shielding layer 90 is used to block the effect of sunlight to prevent the parts inside the vehicle 1000 from being damaged by aging caused by direct sunlight, so as to increase the service life of the parts inside the vehicle 1000 and improve the local adhesion of the parts inside the vehicle 1000 to the window glass 100.

[0106] The heating element 80 may be a heating wire. The heating wire may be an enameled wire, the inner layer material of the enameled wire may be one or more conductor materials such as copper wire, aluminum wire, alloy wire, etc., and the outer layer material of the enameled wire may be one or more insulating materials such as polyurethane Reactive (PUR) and polyimide (PI). The wire diameter range of the enameled wire may be 0.08mm to 0.2mm (including endpoint values ​​of 0.08mm and 0.2mm). The resistance range of the enameled wire may be 0.5Ω / m to 3.7Ω / m (including endpoint values ​​of 0.5Ω / m and 3.7Ω / m). Preferably, the wire diameter range of the enameled wire may be 0.1mm to 0.15mm (including endpoint values ​​of 0.1mm and 0.15mm). The resistance range of the enameled wire may be 0.9Ω / m to 2.33Ω / m (including endpoint values ​​of 0.9Ω / m and 2.33Ω / m). The enameled wire may be directly arranged on the intermediate layer 50 by a crimping process.

[0107] When the heating element 80 is a heating wire, the heating wire can also be a silver paste printed line. Among them, the silver paste is a viscous paste of a mechanical mixture composed of high-purity (99.9%) metallic silver particles, adhesives, solvents, and additives. The silver paste printed line can be arranged on the third surface 41 of the inner glass plate 40 through a printing process, or the silver paste printed line 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 collection area 20. This application does not impose any restrictions on this.

[0108] When the heating element 80 is a heating wire, the heating wire can also be a thin copper wire with a conductive function, which can be a thin copper wire made by forging and drawing a copper wire, and the wire diameter of the thin copper wire can range from 0.002mm to 0.08mm (including endpoint values ​​0.002mm and 0.08mm). The resistance range of the thin copper wire can be 0.5Ω / m to 3.0Ω / m (including endpoint values ​​0.5Ω / m and 3.0Ω / m). The thin copper wire can be integrated on a film of a material such as PET by inlaying or tiling, such as sandwiching a PET film provided with a thin copper wire between the inner glass plate 40 and the outer glass plate 30 through a lamination process. In some embodiments, the heating element 80 can also be a thin tungsten wire.

[0109] A power supply (not shown) is provided in the vehicle 1000 and is used to provide voltage and current to the vehicle window glass 100. According to the actual application scenario of the power supply, the power supply may include a first voltage or a second voltage. In one possible implementation, the first voltage may be 12 to 14V (including endpoint values ​​12V and 14V). In another possible implementation, the second voltage may be 20 to 50V (including endpoint values ​​20V and 50V).

[0110] The structure of the vehicle window glass 100 when the power supply is the first voltage or the second voltage will be described below through two embodiments.

[0111] 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 resistor material made of 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 is constant, it is necessary to reduce the resistance to increase the power in the first signal transmission area 21 and the second signal transmission area 22, so that the heating element 80 can reach the power in the first signal transmission area 21 and the second signal transmission area 22 to achieve the purpose of defrosting, defogging, deicing, etc. Therefore, when the material is the same (ρ and S are 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 loop formed by the heating element.

[0112] Please refer again Figure 4 , Figure 4 for Figure 1 The schematic diagram of the structure of the first embodiment of the vehicle window glass 100 is shown. In order to reduce the loop length of the heating element 80 in the first signal transmission area 21 and the second signal transmission area 22, three specific implementations are provided below to describe in detail the arrangement of the heating element 80 in the first embodiment of the vehicle window glass 100.

[0113] like Figure 4 As shown, Figure 4 A structural schematic diagram of a first implementation mode of a first embodiment of a vehicle window glass is specifically shown.

[0114] In this embodiment, the first signal transmission area 21 and the second signal transmission area 22 are arranged at intervals along the vertical direction of the vehicle window glass 100. The first signal transmission area 21 and the second signal transmission area 22 are both facing one side of 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 can be arranged at intervals 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 arranged at intervals along the horizontal direction or the vertical direction.

[0115] In this embodiment, a shielding area 12 is provided around the first signal transmission area 21, and the first signal transmission area 21 does not overlap with the shielding area 12. The shape of the first signal transmission area 21 can be a triangle, a pentagon, a hexagon, a trapezoid, etc. Exemplarily, the shape of the first signal transmission area 21 is approximately a trapezoid.

[0116] 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 of the shielding area 12 and one side edge of 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 of the main viewing area 11 and one side edge of the shielding area 12. The shape of the second signal transmission area 22 can be a triangle, a pentagon, a hexagon, a trapezoid, etc. Exemplarily, the shape of the second signal transmission area 22 is approximately a trapezoid.

[0117] In this embodiment, the first viewing area 101 of the first sensor 310 is completely disposed in the first signal transmission area 21. The area of ​​the first viewing area 101 is smaller than the area of ​​the first signal transmission area 21. The edge of the first viewing area 101 is spaced from the edge of the first signal transmission area 21. It can be understood that the first viewing area 101 is a closed window. In other possible embodiments, the first viewing area 101 completely overlaps with the first signal transmission area 21. The area of ​​the first viewing area 101 is equal to the area of ​​the first signal transmission area 21.

[0118] In this embodiment, the second viewing area 102 of the second sensor 320 can be completely located in the second signal transmission area 22. The area of ​​the second viewing area 102 is smaller than the area of ​​the second signal transmission area 22. The edge of the second viewing area 102 partially overlaps with the edge of the second signal transmission area 22. It can be understood that the second viewing area 102 is an open window. In other possible embodiments, the second viewing area 102 completely overlaps with the second signal transmission area 22. The area of ​​the second viewing area 102 is equal to the area of ​​the second signal transmission area 22.

[0119] It should be noted that, in this embodiment, the distance between the first viewing angle area 101 and the second viewing angle area 102 is greater than or equal to 3 mm.

[0120] In this embodiment, in order to reduce the loop length formed by the heating element 80 and take into account the control of heating of the first signal transmission area 21 and the second signal transmission area 22, the number of the heating elements 80 is two.

[0121] The heating element 80 includes a first heating element 81 and a second heating element 82. The first heating element 81 and the second heating element 82 are both located between the inner glass plate 40 and the middle layer 50. Alternatively, the first heating element 81 and the second heating element 82 are both located between the outer glass plate 30 and the middle layer 50. Alternatively, the first heating element 81 and the second heating element 82 are both located on the middle 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, part of the first heating element 81 is located in the shielding area 12 and the main viewing area 11, and another part of the first heating element 81 is located in the first signal transmission area 21. Part of the second heating element 82 is located in the shielding area 12 and the main viewing area 11, and another part of the second heating element 82 is located in the second signal transmission area 22.

[0122] 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 for the vehicle window glass 100; the first busbar 70, the second busbar 71 and the third busbar 72 are all arranged at intervals, and the third busbar 72 is 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 through the 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 ends of the first heating element 81 and the second heating element 82 are both connected to the third busbar 72.

[0123] Specifically, in this embodiment, the third busbar 72 is located between the outer glass plate 30 and the inner glass plate 40, and the third busbar 72 is not provided in the shielding area 12. More specifically, the third busbar 72 is provided in the main viewing area 11. The third busbar 72 is stacked on the transparent conductive film 60 and is 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 may be, but is not limited to, a metal copper sheet, a conductive silver paste, and the like.

[0124] Specifically, in the present embodiment, the first heating element 81 includes a first section 811, a second section 812 and a third section 813. The first section 811, the second section 812 and the third section 813 are connected in sequence. The first section 811 is arranged in the shielding area 12 and is used to be electrically connected to the first busbar 70. The first section 811 avoids the second heating element 82. The second section 812 is arranged in the first signal transmission area 21, and the second section 812 extends in a serpentine shape along the vertical direction of the vehicle window glass 100 in the first signal transmission area 21. The third section 813 partially extends along the connecting edge of the second signal transmission area 22 and the main viewing area 11. Another part of the third section 813 is arranged in the main viewing area 11 for electrical connection with the third busbar 72.

[0125] Specifically, in the present embodiment, the second heating element 82 includes a fourth section 821, a fifth section 822 and a sixth section 823. The fourth section 821, the fifth section 822 and the sixth section 823 are connected in sequence. The fourth section 821 is arranged in the shielding area 12 and is used to be electrically connected to the first busbar 70. The fourth section 821 avoids the first signal transmission area 21 and the first heating element 81. The fifth section 822 is arranged in the second signal transmission area 22, and the fifth section 822 extends in a serpentine shape along the vertical direction of the vehicle window glass 100 in the second signal transmission area 22. The sixth section 823 is arranged in the main viewing area 11 and is used to be electrically connected to the third busbar 72. In the present embodiment, there is no restriction on the extension form of the first section 811, the third section 813, the fourth section 821 and the sixth section 823, which can be a serpentine extension that meets the wire spacing, or an extension of other shapes.

[0126] In a possible implementation, the connector 73 provided on the second busbar 71 is connected to the positive electrode of the power source, and the connector 73 provided on the first busbar 70 is connected to the negative electrode of the power source. Therefore, when the power source energizes the first busbar 70 and the second busbar 71, the current will sequentially flow through the connector 73 on the second busbar 71, the second busbar 71, the transparent conductive film 60, the third busbar 72, the third section 813 of the first heating element 81, the second section 812 of the first heating element 81, the first section 811 of the first heating element 81, the first busbar 70, and the connector 73 on the first busbar 70, thereby forming a first loop, and the heating current flows through the first heating element 81 to heat the first signal transmission area 21. At the same time, the current will flow through the joint 73 on the second busbar 71, the second busbar 71, the transparent conductive film 60, the third busbar 72, 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 first busbar 70 and the joint 73 on the first busbar 70 in sequence, thereby forming a second loop, and the heating current flows through the second heating element 82 to heat the second signal transmission area 22. At the same time, in the main viewing area 11, the current will pass through the second busbar 71, the transparent conductive film 60 and the first busbar 70 in sequence, thereby heating the main viewing area 11.

[0127] In another possible implementation, the connector 73 provided on the second busbar 71 is connected to the negative pole of the power supply, and the connector 73 provided on the first busbar 70 is connected to the positive pole 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 the current flow direction of the first circuit, the current flow direction of the second circuit is also opposite to the current flow direction of the second circuit, and the current flow direction of the main viewing area 11 is also opposite to the current flow direction of the main viewing area 11. This application does not impose strict restrictions on this.

[0128] In this embodiment, when current and voltage are provided by a power supply, the first signal transmission area 21, the second signal transmission area 22 and the main viewing area 11 can be heated at the same time, thereby achieving the purpose of defrosting, demisting and deicing the first signal transmission area 21, the second signal transmission area 22 and the main viewing area 11.

[0129] In this embodiment, the first heating element 81 is arranged in the first signal transmission area 21, so that the first heating element 81 controls the heating of the first signal transmission area 21. The second heating element 82 is arranged in the second signal transmission area 22, so that the second heating element 82 controls the heating of the second signal transmission area 22. Therefore, when the power supply is the first voltage, the heating element 80 does not need to pass through the first signal transmission area 21 and the second signal transmission area 22 in sequence, which reduces the loop length of the heating element 80, that is, reduces the length L of the heating element 80 wound into a resistor, reduces the resistance, so that the first heating element 81 and the second heating element 82 reach the power and the first signal transmission area 21 and the second signal transmission area 22 are heated, so as to achieve the purpose of defrosting, defogging, deicing, etc. of the first signal transmission area 21 and the second signal transmission area 22.

[0130] In addition, by independently arranging the first heating element 81 and the second heating element 82 in the first signal transmission zone 21 and the second signal transmission zone 22 respectively, the first signal transmission zone 21 and the second signal transmission zone 22 can adjust the arrangements of the first heating element 81 and the second heating element 82 respectively according to heating requirements, such as the wire diameter, wire spacing, wire length, etc. of the heating element 80, so as to achieve the power density required by the first heating element 81 in the first signal transmission zone 21 and the power density required by the second heating element 82 in the second signal transmission zone 22.

[0131] The first heating element 81 has a relatively high power density range. In a possible implementation, the power density of the first heating element 81 in the first signal transmission area 21 satisfies 2.0 W / dm 2 ~15W / dm 2 (including endpoint value 2.0W / dm 2 and 15W / dm 2), so that the frost, snow, ice, etc. on the first surface 31 of the outer glass plate 30 and the mist on the fourth surface 42 of the inner glass plate 40 located in the first signal transmission area 21 can be melted and evaporated by the heat of the first heating element 81, thereby achieving the purpose of actively defrosting, defogging, and deicing the window glass 100 in the first signal transmission area 21. In another possible embodiment, in order to further shorten the time of defrosting, defogging, and deicing, the power density of the first heating element 81 in the first signal transmission area 21 meets 8.0W / dm 2 ~15W / dm 2 (including endpoint value 8.0W / dm 2 and 15W / dm 2 In another possible implementation manner, the power density of the first heating element 81 in the first signal transmission area 21 satisfies 9.0 W / dm 2 ~11W / dm 2 (including endpoint value 9.0W / dm 2 and 11W / dm 2 ) to further shorten the time for defrosting, defogging and deicing.

[0132] The second heating element 82 has a relatively high power density range. In a possible implementation, the power density of the second heating element 82 in the second signal transmission area 22 satisfies 2.0 W / dm 2 ~15W / dm 2 (including endpoint value 2.0W / dm 2 and 15W / dm 2 ), so that the frost, snow, ice, etc. on the first surface 31 of the outer glass plate 30 and the mist on the fourth surface 42 of the inner glass plate 40 in the second signal transmission area 22 can be melted and evaporated by the heat of the second heating element 82, thereby achieving the purpose of actively defrosting, defogging, and deicing the window glass 100 in the second signal transmission area 22. In another possible embodiment, in order to further shorten the time of defrosting, defogging, and deicing, the power density of the second heating element 82 in the second signal transmission area 22 meets 8.0W / dm 2 ~15W / dm 2 (including endpoint value 8.0W / dm 2 and 15W / dm 2 In another possible implementation manner, the power density of the second heating element 82 in the second signal transmission area 22 satisfies 9.0 W / dm 2 ~11W / dm 2 (including endpoint value 9.0W / dm 2 and 11W / dm 2 ) to further shorten the time for defrosting, defogging and deicing.

[0133] It should be noted that, considering the influence of the wire spacing of 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 respectively on the heating effect of the first signal transmission area 21 and the second signal transmission area 22, 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 diameters of the first heating element 81 and the second heating element 82 are both less than or equal to 0.18 mm. Preferably, the wire diameters of the first heating element 81 and the second heating element 82 are both less than or equal to 0.12 mm. The wire spacing of the first heating element 81 and the second heating element 82 must be greater than or equal to 20 mm. Among them, the wire spacing of the first heating element 81 is the winding spacing distance of the first heating element 81. The wire spacing of the second heating element 82 is the winding spacing distance of the second heating element 82.

[0134] See also Figure 5 , Figure 5 for Figure 1 The schematic structural diagram of the second implementation of the first embodiment of the vehicle window glass 100 is shown.

[0135] Different from the first implementation of the first embodiment mentioned above, in this implementation, the vehicle window glass 100 does not include the third bus bar 72, the opposite ends of the first heating element 81 in the length direction are electrically connected to the first bus bar 70, and the opposite ends of the second heating element 82 in the length direction are also electrically connected to the first bus bar 70.

[0136] Specifically, the first busbar 70 includes a first subsection 701 and a second subsection 702, the first subsection 701 and the second subsection 702 are arranged at intervals and insulated, and the first subsection 701, the second subsection 702 and the second busbar 71 are arranged at intervals; the first subsection 701 is electrically connected to the second subsection 702 through the heating element 80. In this embodiment, the first subsection 701 and the second subsection 702 are both connected to the power supply of the vehicle 1000, and the power supply of the vehicle 1000 provides the first voltage for the vehicle window glass 100. Specifically, one end of the first heating element 81 and the second heating element 82 are both connected to the first subsection 701, and the other ends of the first heating element 81 and the second heating element 82 are both connected to the second subsection 702. That is, the first section 811 of the first heating element 81 and the fourth section 821 of the second heating element 82 are both connected to the first subsection 701. The third section 813 of the first heating element 81 and the sixth section 823 of the second heating element 82 are both connected to the second subsection 702.

[0137] In one possible implementation, connectors 73 are provided on the first sub-segment 701 and the second sub-segment 702, respectively. The connector 73 provided on the first sub-segment 701 is connected to the positive pole of the power supply, and the connector 73 provided on the second sub-segment 702 is connected to the negative pole of the power supply. Therefore, when the power supply energizes the first busbar 70, the current will flow through the connector 73 on the first sub-segment 701 of the first busbar 70, the first sub-segment 701, the first section 811 of the first heating element 81, the second section 812 of the first heating element 81, the third section 813 of the first heating element 81, the second sub-segment 702 and the connector 73 on the second sub-segment 702 in sequence, thereby forming a third circuit, and the heating current flows through the first heating element 81 to heat the first signal transmission area 21. At the same time, the current will flow through the joint 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 joint 73 on the second sub-segment 702 in sequence to form a fourth loop, and the heating current flows through the second heating element 82 to heat the second signal transmission area 22.

[0138] In another possible implementation, the connector 73 provided in the first sub-segment 701 is connected to the negative pole of the power supply, the connector 73 of the second sub-segment 702 is connected to the positive pole of the power supply, the current flow direction of the third loop is opposite to the current flow direction of the third loop, and the current flow direction of the fourth loop is also opposite to the current flow direction of the fourth loop. This implementation does not impose strict restrictions on this.

[0139] In this embodiment, the first busbar 70 is disconnected into the second subsection 702 and the first subsection 701 to avoid short circuit between the first heating element 81 and the second heating element 82. By energizing the first busbar 70, the current flows through the first heating element 81 and the second heating element 82 at the same time, and the first signal transmission area 21 and the second signal transmission area 22 can be heated at the same time, meeting the driver's needs for defog, snow removal, and ice removal in the first signal transmission area 21 and the second signal transmission area 22. 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 first signal transmission area 21 and the second signal transmission area 22 can adjust the arrangement of the first heating element 81 and the second heating element 82 according to the heating requirements, such as the wire diameter, wire spacing, wire length, etc. of the heating element 80, so as to achieve 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.

[0140] 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, so that the heating of the main viewing area 11 is separated from the heating of the first signal transmission area 21 and the second signal transmission area 22, further meeting the customer's heating needs for the actual application of the vehicle window glass 100.

[0141] It should be noted that the contents in this embodiment that are the same as those in the first embodiment of the first embodiment described above will not be described in detail.

[0142] See also Figure 6 , Figure 6 for Figure 1 The schematic structural diagram of the third implementation mode of the first embodiment of the vehicle window glass is shown.

[0143] Different from the second implementation of the first embodiment described above, in this implementation, along the vertical direction of the window glass 100, the first signal transmission area 21 and the second signal transmission area 22 are both arranged below the shielding area 12, and are both spaced apart from the shielding area 12. That is, the window glass 100 also includes an information collection area 20 for signal transmission of the first sensor 310 and the second sensor 320, and the first signal transmission area 21 and the second signal transmission area 22 are both located in the information collection area 20, and the transparent conductive film 60 avoids the information collection area 20. In this implementation, 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. Exemplarily, the first signal transmission area 21 is located on the left side of the second signal transmission area 22.

[0144] In this embodiment, the first signal transmission area 21 and the second signal transmission area 22 are both surrounded by a main viewing area 11, and neither overlaps with the main viewing area 11. 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 vehicle window glass 100 and helps to better achieve the heating of the main viewing area 11 and the information collection area 20.

[0145] In this embodiment, the first busbar 70 further includes a third subsection 703. The third subsection 703 is disposed between the first subsection 701 and the second subsection 702, and is spaced apart from and insulated from the first subsection 701 and the second subsection 702.

[0146] In a possible implementation, the third sub-segment 703 is provided with a joint (not shown). The first sub-segment 701 and the third sub-segment 703 are electrically connected to the power supply through the joint. 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 joint 73 provided in the first sub-segment 701 is connected to the positive pole of the power supply, and the joint provided in the third sub-segment 703 is connected to the negative pole of the power supply. Therefore, when the power supply energizes the first busbar 70, the current will flow through the joint 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 joint located in the third sub-segment 703 in sequence, thereby forming a fifth loop, and the heating current flows through the first heating element 81 to heat the first signal transmission area 21.

[0147] 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 the power supply through 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 provided in the second sub-segment 702 is connected to the positive pole of the power supply, and the connector provided in the third sub-segment 703 is connected to the negative pole of the power supply. The current will flow 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 in sequence, thereby forming a sixth loop, and the heating current flows through the second heating element 82 to heat the second signal transmission area 22.

[0148] In another possible implementation, the connector 73 provided at the first sub-segment 701 is connected to the negative pole of the power supply, the connector 73 provided at the second sub-segment 702 is connected to the negative pole of the power supply, and the connector provided at the third sub-segment 703 is connected to the positive pole of the power supply. The current flow direction of the fifth loop is opposite to the current flow direction of the fifth loop, and the current flow direction of the sixth loop is also opposite to the current flow direction of the sixth loop. This implementation does not impose strict restrictions on this.

[0149] In this embodiment, the first busbar 70 is broken into three sections to avoid short circuit 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 separately to achieve the first heating element 81 heating the first signal transmission area 21 and the second heating element 82 heating the second signal transmission area 22, which not only meets the driver's needs for defog, snow removal, and ice removal in any area of ​​the first signal transmission area 21 or the second signal transmission area 22, but also achieves the purpose of saving energy.

[0150] 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, thereby further satisfying the customer's heating needs for the actual application of the vehicle window glass 100.

[0151] In another possible implementation, the first sub-segment 701 and the second sub-segment 702 are both connected to the power supply of the vehicle 1000, the power supply of the vehicle 1000 provides the first voltage for the vehicle 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. In other words, the third sub-segment 703 is not provided with a connector connected to the power supply, and the current will flow through the first heating element 81 and the second heating element 82 at the same time to control the heating of the first signal transmission area 21 and the second signal transmission area 22 at the same time. It should be noted that the same contents as the second implementation of the first embodiment mentioned above in this implementation are not repeated.

[0152] 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 voltage of the power source is 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, so as to avoid excessive voltage causing excessive power in the first signal transmission area 21 and the second signal transmission area 22 to generate local hot spots while ensuring the heating conditions of the first signal transmission area 21 and the second signal transmission area 22, thereby preventing the local temperature of the first signal transmission area 21 and the second signal transmission area 22 from being too high to cause the window glass 100 to burst. Therefore, under the condition of the same material (ρ and S remain unchanged), it is necessary to increase the length L of the resistor wound by the heating element 80, that is, to increase the loop length formed by the heating element 80.

[0153] See also Figure 7 , Figure 7 for Figure 1 The schematic diagram of the structure of the second embodiment of the vehicle window glass shown in FIG. Different from the above-mentioned first embodiment, in this embodiment, in order to increase the loop length of the heating element 80 of the vehicle window glass 100, the number of the heating element 80 is one. One heating element 80 passes through the first signal transmission area 21 and the second signal transmission area 22 as much as possible at the same time to increase the effective utilization rate of the heating element 80, reduce the power of the heating element 80, and prevent the power of the heating element 80 from being too high to cause local hot spots in the information collection area 20. Specifically, the heating element 80 includes at least one heating wire, and the at least one heating wire extends through the first signal transmission area 21 and the second signal transmission area 22.

[0154] It should be noted that the same contents as those of the first embodiment will not be described in detail. Five specific implementations will be provided below to describe the arrangement of the heating element 80 in the second embodiment of the vehicle window glass 100 in detail.

[0155] Please refer again Figure 7 , Figure 7 The structural schematic diagram of the first implementation mode of the second embodiment of the vehicle window glass is specifically shown.

[0156] In this embodiment, one end of the heating element 80 in the length direction is connected to the first bus bar 70 , and the other end of the heating element 80 in the length direction is connected to the third bus bar 72 .

[0157] Specifically, the heating element 80 includes a seventh segment 83, an eighth segment 84 and a ninth segment 85, and the seventh segment 83, the eighth segment 84 and the ninth segment 85 are connected in sequence. The seventh segment 83 is arranged in the shielding area 12 and is electrically connected to the first busbar 70. The eighth segment 84 is at least arranged in the first signal transmission area 21 and the second signal transmission area 22. Along the vertical direction of the vehicle window glass 100, the eighth segment 84 extends in a serpentine shape in the first signal transmission area 21 and the second signal transmission area 22. The ninth segment 85 is arranged in the main viewing area 11 and is electrically connected to the third busbar 72. In this embodiment, there is no restriction on the extension form of the seventh segment 83 and the ninth segment 85, which can be an extension of any shape that satisfies the wire spacing. Among them, the wire spacing of the heating element 80 is the spacing distance of the winding of the heating element 80.

[0158] In a possible implementation, the connector 73 on the second busbar 71 is connected to the positive electrode of the power supply, and the connector 73 on the first busbar 70 is connected to the negative electrode of the power supply. Therefore, the current will flow through the connector 73 located at the second busbar 71, the second busbar 71, the transparent conductive film 60, the third busbar 72, the ninth section 85 of the heating element 80, the eighth section 84 of the heating element 80, the seventh section 83 of the heating element 80, the first busbar 70, and the connector 73 located at the first busbar 70 in sequence, thereby forming a seventh loop, and 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 arranged in the first signal transmission area 21 and the second signal transmission area 22 at the same time. The power supply provides current and voltage to the first busbar 70 and the second busbar 71, so that the heating element 80 can heat the first signal transmission area 21 and the second signal transmission area 22. At the same time, the transparent conductive film 60 is also used to heat the main viewing area 11.

[0159] In another possible implementation, the connectors 73 on the first busbar 70 and the second busbar 71 are connected to the positive and negative electrodes of the power supply respectively, and the current flow direction of the seventh loop is opposite to the current flow direction of the seventh loop mentioned above. This implementation does not impose strict restrictions on this.

[0160] 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.

[0161] See also Figure 8 , Figure 8 for Figure 1 The schematic structural diagram of the second implementation of the second embodiment of the vehicle window glass is shown.

[0162] Different from the first implementation of the second embodiment, in this implementation, the vehicle window glass 100 does not include the third bus bar 72. Both opposite ends of the heating element 80 in the length direction are connected to the first bus bar 70.

[0163] The first busbar 70 includes a first subsection 701 and a second subsection 702. The first subsection 701 and the second subsection 702 are spaced apart and insulated. The seventh section 83 of the heating element 80 is connected to the first subsection 701, and the ninth section 85 of the heating element 80 is connected to the second subsection 702.

[0164] In a possible implementation, the connector 73 provided on the first sub-segment 701 is connected to the positive pole of the power supply, and the connector 73 provided on the second sub-segment 702 is connected to the negative pole of the power supply. Therefore, when the power supply energizes the first busbar 70, the current will flow through the connector 73 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 on the second sub-segment 702 in sequence, thereby forming an eighth loop, and the heating current flows through the heating element 80 to heat the first signal transmission area 21 and the second signal transmission area 22.

[0165] In another possible implementation, the connector 73 provided in the first sub-segment 701 is connected to the negative pole of the power supply, the connector 73 in the second sub-segment 702 is connected to the positive pole of the power supply, and the current flow direction of the eighth loop is opposite to the current flow direction of the aforementioned eighth loop. This implementation is not strictly limited to this.

[0166] It should be noted that in this embodiment, the first busbar 70 is broken into two sections to avoid a short circuit in the heating element 80. When the first busbar 70 is powered on, the heating element 80 can simultaneously control the first signal transmission area 21 and the second signal transmission area 22 to heat. When the power supply also powers the second busbar 71, the transparent conductive film 60 heats the main viewing area 11, so that the heating of the main viewing area 11 is separated from the heating of the first signal transmission area 21 and the second signal transmission area 22 to meet the different practical application requirements of customers. It should be noted that the same contents of this embodiment as the first embodiment of the second embodiment described above will not be repeated.

[0167] See also Fig. 9 , Fig. 9 for Figure 1 The schematic structural diagram of the third implementation mode of the second embodiment of the vehicle window glass is shown.

[0168] In this embodiment, the vehicle window glass 100 further includes an information collection area 20 for signal transmission of the first sensor 310 and the second sensor 320, and the first signal transmission area 21 and the second signal transmission area 22 are both located in the information collection area 20, and the transparent conductive film 60 avoids the information collection area 20. Specifically, different from the second embodiment of the second embodiment described above, in this embodiment, along the vertical direction of the vehicle window glass 100, the first signal transmission area 21 and the second signal transmission area 22 are both arranged below the shielding area 12, and are both spaced apart from the shielding area 12. 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. The first signal transmission area 21 and the second signal transmission area 22 are both surrounded by a main viewing area 11, and neither overlaps with the main viewing area 11. Exemplarily, the first signal transmission area 21 is located on the left side of the second signal transmission area 22.

[0169] 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.

[0170] See also Fig.10 , Fig.10 for Figure 1 The structure diagram of the fourth implementation mode of the second embodiment of the vehicle window glass shown in FIG. Fig.10 The dotted line in FIG. 1 not only indicates the boundary between the first viewing angle area 101 and the second viewing angle area 102 , but also indicates the boundary between the first signal transmission area 21 and the second signal transmission area 22 .

[0171] In this embodiment, the vehicle window glass 100 further includes an information collection area 20 for signal transmission of the first sensor 310 and the second sensor 320, and the first signal transmission area 21 and the second signal transmission area 22 are both located in the information collection area 20, and the transparent conductive film 60 avoids the information collection area 20. Specifically, different from the second embodiment of the second embodiment, 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, and the first signal transmission area 21 is located above the second signal transmission area 22 and close to one side of the top of the vehicle 1000. The first viewing area 101 is completely set in the first signal transmission area 21, and the area of ​​the first viewing area 101 is smaller than the area of ​​the first signal transmission area 21. The second viewing area 102 is completely set in the second signal transmission area 22. The area of ​​the second viewing area 102 is smaller than the area of ​​the second signal transmission area 22. The first viewing area 101 and the second viewing area 102 are arranged at intervals along the vertical direction of the vehicle window glass 100.

[0172] In other possible implementations, the first viewing area 101 may completely overlap with the first signal transmission area 21, and the area of ​​the first viewing area 101 is equal to the area of ​​the first signal transmission area 21. The second viewing area 102 may completely overlap with the second signal transmission area 22, and the area of ​​the second viewing area 102 is equal to the area of ​​the second signal transmission area 22. It can be understood that the sum of the areas of the first viewing area 101 and the second viewing area 102 is less than or equal to the sum of the areas of the first signal transmission area 21 and the second signal transmission area 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 of the second implementation of the above-mentioned second embodiment are not repeated.

[0173] See also Fig.11 , Fig.11 for Figure 1 The schematic structural diagram of the fifth implementation mode of the second embodiment of the vehicle window glass is shown.

[0174] Different from the fourth implementation of the second embodiment mentioned above, in this implementation, when the second sensor 320 is a laser radar, considering the angle of the vehicle window glass 100 when installed on the vehicle body 200, part of the eighth section 84 is located in the first signal transmission area 21 and extends in a serpentine shape along the vertical direction of the vehicle window glass 100, and another part of the eighth section 84 is located in the second signal transmission area 22 and extends in a serpentine shape along the horizontal direction of the vehicle window glass 100, so as to reduce 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 reduce the physical obstruction of the heating element 80 on the transmission and / or reception signals of the second sensor 320 to the second signal transmission area 22, so as to facilitate the second sensor 320 to obtain complete image information.

[0175] 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 same contents of this embodiment as those of the fourth embodiment of the second embodiment are not repeated here.

[0176] See also Fig.12 , Fig.12 It is a line graph showing the influence of the heating element 80 with different wire diameters and different wire spacings on the laser radar detection accuracy as the radar channel changes in the present application.

[0177] As can be seen from the figure, when the channel of the laser radar is 64.00, when the wire diameter of the heating element 80 is 0.12mm and the wire spacing is 20mm (i.e. Fig.12 The corresponding detection accuracy (Probability Of Detection, POD) of the laser radar is about 97%. When the wire diameter of the heating element 80 is 0.12mm and the wire spacing is 15mm (i.e. Fig.12 The detection accuracy of the laser radar is about 87%. Therefore, it can be seen that the wire spacing of the heating element 80 has an impact on the detection accuracy of the laser radar.
