Detailed implementation manners

[0067] The technical solutions provided by the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments described in the present application belong to the protection scope of the present application.

[0068] References to "embodiments" in this application mean that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appearing in various places in the specification does not necessarily refer to the same embodiment, nor is it an exclusive, independent, or alternative embodiment to other embodiments. Those skilled in the art can explicitly and implicitly understand that the embodiments described in this application can be combined with other embodiments.

[0069] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example: A component or device comprising one or more parts is not limited to the one or more parts listed, but optionally further includes one or more parts not listed but inherent to the product exemplified, or one or more parts that it should have based on the described function.

[0070] Please refer to Figures 1 to 4 , Figure 1 FIG. 100 is a schematic structural diagram of a glass component 100 provided for an embodiment of this application. Figure 2 is Figure 1 A schematic structural diagram of the glass body 10 in the glass component 100 shown in FIG. Figure 3 is Figure 1 A schematic structural diagram of a wire unit 20 in the glass component 100 shown in FIG. Figure 4 is Figure 1 A schematic structural diagram of a coating unit 30 in the glass component 100 shown in FIG. The glass component 100 includes a glass body 10, a wire unit 20, and a coating unit 30.

[0071] This application does not specifically limit the material of the glass body 10. For example, the material of the glass body 10 can include one or more of soda-lime, high-aluminum, lithium-aluminum, or borosilicate. This application does not specifically limit the thickness of the glass body 10. For example, the thickness range of the glass body 10 can be 0.7 mm to 4.0 mm. This application does not specifically limit the shape of the glass body 10. For example, the glass body 10 can be a flat glass plate, or the glass body 10 can be a curved glass plate. When the glass body 10 is a flat glass plate, the surface of the glass body 10 is flat. When the glass body 10 is a curved glass plate, the surface of the glass body 10 can be a convex curved surface or a concave curved surface.

[0072] The surface of the glass body 10 has a first region 101 and a second region 102. The first region 101 surrounds the second region 102 on all sides. It can be understood that the first region 101 forms the edge region of the glass body 10, and the second region 102 forms the central region of the glass body 10. In a possible embodiment, the first region 101 includes a wiper stay region 110 located at the bottom of the glass body 10, that is, the docking region corresponding to the wiper. The second region 102 includes an information collection region 120. The information collection region 120 can correspond to the camera region of the Advanced Driving Assistant System (ADAS).

[0073] This application does not make specific limitations on the area size of the information collection region 120. Optionally, the area of the information collection region 120 can be greater than or equal to 0.5 dm2 and less than or equal to 10 dm2. In a possible embodiment, the area of the information collection region 120 can be 1.9 dm2.

[0074] The wire unit 20 is formed by one or more sub-wire units. The wire unit 20 is provided in the first region 101. In a possible embodiment, the wire unit 20 can be provided in the first region 101 on the surface of the glass body 10 by bonding. In another possible embodiment, the wire unit 20 can be formed in the first region 101 on the surface of the glass body 10 by a metal printing process.

[0075] The coating unit 30 is formed by one or more sub-coating units. The coating unit 30 is provided in the second region 102. In a possible embodiment, the coating unit 30 can be directly deposited in the second region 102 on the surface of the glass body 10. In another possible embodiment, the coating unit 30 can be deposited on a substrate, where the substrate includes but is not limited to a plastic substrate or a resin substrate. By laminating the substrate with the glass body 10, the coating unit 30 is provided in the second region 102 on the surface of the glass body 10. Among them, the deposition method includes but is not limited to magnetron sputtering.

[0076] The coating unit 30 includes a first sub-coating unit 301 provided in the information collection region 120. The first sub-coating unit 301 is connected in series electrically with the wire unit 20. The first sub-coating unit 301 can heat the information collection region 120 after being powered on.

[0077] In this embodiment, the first sub-coating unit 301 is connected in series with the wire unit 20. That is, the positive electrode of the power supply, the wire unit 2020, the first sub-coating unit 301, and the negative electrode of the power supply form a series circuit. The wire unit 20 and the first sub-coating unit 301 can be directly electrically connected or indirectly electrically connected. Among them, the positive electrode of the power supply is represented by + in the drawing, and the negative electrode of the power supply is represented by ﹣ in the drawing.

[0078] As Figure 5 shown, Figure 5 is Figure 4 a schematic cross-sectional view of the coating unit 30 along the line A-A. The first sub-coating unit 301 includes at least one metal conductive layer 310.

[0079] This application does not specifically limit the number of metal conductive layers 310 included in the first sub-coating unit 301. For example, the first sub-coating unit 301 can include one or more metal conductive layers 310. In the embodiment where the first sub-coating unit 301 includes multiple metal conductive layers 310, the multiple metal conductive layers 310 are stacked, and the specific number of layers of the metal conductive layer 310 includes but is not limited to two layers, or three layers, or four layers, or five layers, or six layers, or seven layers, or eight layers. The material of the metal conductive layer 310 can include one or more of silver, nickel, and cadmium.

[0080] The glass component 100 provided by this application includes a glass body 10, a wire unit 20, and a coating unit 30. The first sub-coating unit 301 of the coating unit 30 is disposed in the information collection area 120 of the glass body 10, and the wire unit 20 is disposed in the first area 101 of the glass body 10. In this way, when powered on, the first sub-coating unit 301 and the wire unit 20 can respectively realize local heating and defrosting of the information collection area 120 and the first area 101. When applied to a high-voltage power supply system for a whole vehicle, even if the area of the information collection area 120 is small, resulting in a small resistance of the first sub-coating unit 301, the wire unit 20 can also play a voltage-dividing role, thereby reducing the power of the first sub-coating unit 301 and making the hot spots meet the requirements when the first sub-coating unit 301 heats the information collection area 120 under a high-voltage power supply system; at the same time, since the first sub-coating unit 301 emits electricity as a whole and does not need to transfer heat through the glass body 10, it will not cause the glass body 10 to be overheated and softened, and thus is not likely to have an adverse impact on the optical performance of the glass component 100. In addition, the thickness of the coating unit 30 can be nanoscale, which can ensure the light transmittance of the coating unit 30, so that the first area 101 of the glass component 100 has a transparent and foreign-object-free appearance.

[0081] In the embodiment where the information acquisition area 120 corresponds to the camera area of ADAS, if the information acquisition area 120 is heated by a metal wire, the opaque metal wire will affect the image acquisition of the camera, resulting in a reduction in the reliability of ADAS. Moreover, when the camera acquires images of signal lights or vehicle lights, the opaque metal wire is prone to light diffraction or glare phenomena, which will also affect the reliability of ADAS. Therefore, in this application, the first sub-coating unit 301 is used to heat the information acquisition area 120. Since the thickness of the first sub-coating unit 301 is nanoscale, it appears transparent and has no foreign objects, so it will not affect the image acquisition of the camera, nor will it produce light diffraction or glare phenomena, thereby ensuring the reliability of ADAS.

[0082] In a possible embodiment, please refer to Figures 1 to 4 , the second area 102 further includes a visible area 121. The coating unit 30 further includes a second sub-coating unit 302 disposed in the visible area 121. The second sub-coating unit 302 and the first sub-coating unit 301 are spaced apart, and the spacing distance between the second sub-coating unit 302 and the first sub-coating unit 301 is greater than or equal to 10 μm.

[0083] As Figure 5 shown, the second sub-coating unit 302 includes at least one metal reflection layer 320, and the metal reflection layer 320 is used to reflect light.

[0084] In this embodiment, the visible area 121 and the information acquisition area 120 form the second area 102. The second sub-coating unit 302 and the first sub-coating unit 301 form the coating unit 30. This application does not make specific limitations on the number of metal reflection layers 320 included in the second sub-coating unit 302. For example, the second sub-coating unit 302 may include one or more metal reflection layers 320. In the embodiment where the second sub-coating unit 302 includes multiple metal reflection layers 320, the multiple metal reflection layers 320 are stacked, and the specific number of layers of the metal reflection layer 320 includes but is not limited to two layers, or three layers, or four layers, or five layers, or six layers, or seven layers, or eight layers. The material of the metal reflection layer 320 may include one or more of silver, nickel, and cadmium.

[0085] This application does not make specific limitations on the area size of the visible area 121. In a possible embodiment, the area of the visible area 121 may be greater than or equal to 15 dm2 and less than or equal to 20 dm2. Optionally, the area of the visible area 121 may be 18.7 dm2.

[0086] Optionally, after forming the integral coating unit 30 on the glass body 10, by performing a partition treatment on the integral coating unit 30, a part of the coating unit 30 forms the first sub-coating unit 301, and another part of the coating unit 30 forms the second sub-coating unit 302. It can be understood that at this time, the number of layers, the thickness of each layer, and the material of each layer of the first sub-coating unit 301 and the second sub-coating unit 302 can be the same. In other words, the material of the metal reflection layer 320 can be the same as the material of the metal conductive layer 310. The thickness of the metal reflection layer 320 can be the same as the thickness of the metal conductive layer 310. The number of layers of the metal reflection layer 320 included in the second sub-coating unit 302 can be the same as the number of layers of the metal conductive layer 310 included in the first sub-coating unit 301.

[0087] This application does not specifically limit the spacing distance between the second sub-coating unit 302 and the first sub-coating unit 301. Exemplarily, the spacing distance between the second sub-coating unit 302 and the first sub-coating unit 301 is 10 μm, or 12 μm, or 13 μm, or 15 μm, or 16 μm, or 18 μm, or 20 μm, or 24 μm.

[0088] Among them, the second sub-coating unit 302 and the wire unit 20 can also be spaced apart. In one possible embodiment, the spacing distance between the second sub-coating unit 302 and the wire unit 20 can be greater than or equal to the spacing distance between the second sub-coating unit 302 and the first sub-coating unit 301. Of course, in other possible embodiments, the spacing distance between the second sub-coating unit 302 and the wire unit 20 can also be less than the spacing distance between the second sub-coating unit 302 and the first sub-coating unit 301.

[0089] In this embodiment, by forming the second sub-coating unit 302 in the second area 102 on the surface of the glass body 10, since the second sub-coating unit 302 can include at least one metal reflection layer 320, and the metal reflection layer 320 is used to reflect light, the second sub-coating unit 302 can play a heat insulation role. In addition, the spacing distance between the second sub-coating unit 302 and the first sub-coating unit 301 is greater than or equal to 10 μm, which can ensure that the spacing distance between the second sub-coating unit 302 and the first sub-coating unit 301 is not too small, and can avoid forming an electrical connection between the second sub-coating unit 302 and the first sub-coating unit 301, resulting in a short circuit situation.

[0090] In one possible embodiment, please refer to Figures 5 to 7 , Figure 6 is Figure 4 another cross-sectional schematic diagram of the coating unit 30 along the A-A line, Figure 7 is Figure 4Another schematic cross-sectional view of the coating unit 30 shown along line A-A. The first sub-coating unit 301 further includes at least two first dielectric layers 311, and each of the metal conductive layers 310 is located between two adjacent first dielectric layers 311. The second sub-coating unit 302 further includes at least two second dielectric layers 321, and each of the metal reflective layers 320 is located between two adjacent second dielectric layers 321.

[0091] Specifically, the first sub-coating unit 301 may include N metal conductive layers 310 and N + 1 first dielectric layers 311. The second sub-coating unit 302 may include N metal reflective layers 320 and N + 1 second dielectric layers 321. Wherein, N is an integer greater than or equal to 1. The following gives examples of the metal conductive layer 310, the first dielectric layer 311 included in the first sub-coating unit 301, the metal reflective layer 320, and the second dielectric layer 321 included in the second sub-coating unit 302.

[0092] Optionally, as Figure 5 shown, in an embodiment where the first sub-coating unit 301 includes one metal conductive layer 310, the first sub-coating unit 301 further includes two first dielectric layers 311, and the metal conductive layer 310 is disposed between the two first dielectric layers 311. In an embodiment where the second sub-coating unit 302 includes one metal reflective layer 320, the second sub-coating unit 302 further includes two second dielectric layers 321, and the metal reflective layer 320 is disposed between the two second dielectric layers 321.

[0093] As Figure 6 shown, in an embodiment where the first sub-coating unit 301 includes two metal conductive layers 310, the first sub-coating unit 301 further includes three first dielectric layers 311. The first dielectric layer 311 closest to the glass body 10 is the innermost first dielectric layer 311, the first dielectric layer 311 farthest from the glass body 10 is the outermost first dielectric layer 311, and the first dielectric layer 311 between the innermost first dielectric layer 311 and the outermost first dielectric layer 311 is the intermediate first dielectric layer 311. The metal conductive layer 310 relatively close to the glass body 10 is the inner metal conductive layer 310, and the metal conductive layer 310 relatively far from the glass body 10 is the outer metal conductive layer 310. The inner metal conductive layer 310 is located between the innermost first dielectric layer 311 and the intermediate first dielectric layer 311, and the outer metal conductive layer 310 is disposed between the intermediate first dielectric layer 311 and the outermost first dielectric layer 311.

[0094] In an embodiment where the second sub-coating unit 302 includes two metal reflection layers 320, the second sub-coating unit 302 further includes three second dielectric layers 321. The second dielectric layer 321 closest to the glass body 10 is the innermost second dielectric layer 321, the second dielectric layer 321 farthest from the glass body 10 is the outermost second dielectric layer 321, and the second dielectric layer 321 between the innermost second dielectric layer 321 and the outermost second dielectric layer 321 is the middle second dielectric layer 321. The metal reflection layer 320 relatively closer to the glass body 10 is the inner metal reflection layer 320, and the metal reflection layer 320 relatively farther from the glass body 10 is the outer metal reflection layer 320.

[0141] Among them, the diameters of the first wire segment 210, the second wire segment 220, the third wire segment 230, the fourth wire segment 240, the fifth wire segment 250, and the sixth wire segment 260 may be the same or different.

[0142] By making the diameters of the first wire segment 210, the second wire segment 220, the third wire segment 230, the fourth wire segment 240, the fifth wire segment 250, and the sixth wire segment 260 all in the range of 0.02 mm to 0.2 mm, it is beneficial to realize the automatic layout of the wire unit 20.

[0143] In a possible embodiment, the first wire segment 210, the second wire segment 220, the third wire segment 230, the fourth wire segment 240, the fifth wire segment 250, and the sixth wire segment 260 are all enameled wires. It can be understood that the first wire segment 210 includes a first wire conductor and a first insulating layer wrapped around the outer periphery of the first wire conductor.

[0145] Making the first wire segment 210, the second wire segment 220, the third wire segment 230, the fourth wire segment 240, the fifth wire segment 250, and the sixth wire segment 260 all enameled wires is beneficial to reducing the processing and preparation difficulty of the glass component 100.

[0146] Furthermore, please refer to Figure 8 and Figure 9 , Figure 8 which is another structural schematic diagram of the glass component 100 provided by the embodiment of the present application. Figure 9 is Figure 8 a structural schematic diagram of the first bus bar 401 and the second bus bar 402 in the glass component 100 shown. The glass component 100 further includes a bus bar 40. The wire unit 20, the bus bar 40, and the first sub-coating unit 301 are connected in series electrically. In this embodiment, the bus bar 40 is at least partially disposed on the first sub-coating unit 301. That is, the first wire segment 210, the bus bar 40, and the metal conductive layer 310 are connected in series electrically in sequence.

[0147] In this embodiment, the busbar 40 includes a first busbar 401. It can be understood that one end of the first busbar 401 is electrically connected to the first wire segment 210, and the other end of the first busbar 401 is electrically connected to the metal conductive layer 310. Among them, the first busbar 401 and the first wire segment 210 can be directly electrically connected or indirectly electrically connected. The first busbar 401 and the metal conductive layer 310 can be directly electrically connected or indirectly electrically connected. In the following embodiments, it is taken as an example that the first busbar 401 is directly electrically connected to the first wire segment 210 and the first busbar 401 is directly electrically connected to the metal conductive layer 310.

[0148] The diameter of the first busbar 401 can be greater than or equal to the diameter of the first wire segment 210. In a possible embodiment, the diameter range of the first busbar 401 can be 0.45 mm to 0.6 mm. The material of the first busbar 401 can be silver.

[0149] The busbar 40 further includes a second busbar 402. The first wire segment 210, the first busbar 401, the metal conductive layer 310, and the second busbar 402 are sequentially connected in series and electrically connected.

[0150] It can be understood that one end of the second busbar 402 is electrically connected to the metal conductive layer 310, and the other end of the second busbar 402 is used to be electrically connected to the positive electrode or the negative electrode of the power supply. Among them, the second busbar 402 and the metal conductive layer 310 can be directly electrically connected or indirectly electrically connected. The second busbar 402 and the positive electrode or the negative electrode of the power supply can be directly electrically connected or indirectly electrically connected. In the following embodiments, it is taken as an example that the second busbar 402 is directly electrically connected to the metal conductive layer 310 and the first busbar 401 is indirectly electrically connected to the positive electrode or the negative electrode of the power supply.

[0151] The diameter of the second busbar 402 can be greater than or equal to the diameter of the first wire segment 210. In a possible embodiment, the diameter range of the second busbar 402 can be 0.45 mm to 0.6 mm. The diameter of the second busbar 402 can be the same as or different from the diameter of the first busbar 401. The material of the second busbar 402 can be silver. The material of the second busbar 402 can be the same as or different from the material of the first busbar 401.

[0152] Among them, the first busbar 401 is a metal printed wire, and / or the second busbar 402 is a metal printed wire. In a possible embodiment, the first busbar 401 can be a silver paste printed wire, and the second busbar 402 can be a silver paste printed wire.

[0153] Since the first wire segment 210, the second wire segment 220, the third wire segment 230, and the fourth wire segment 240 included in the wire unit 20 can be enameled wires, while the metal conductive layer 310 included in the first sub-coating unit 301 is a coating layer with a thickness usually in the nanometer range, it is difficult to directly electrically connect the first wire segment 210, the second wire segment 220, the third wire segment 230, and the fourth wire segment 240 to the metal conductive layer 310, and even if it can be achieved, the reliability is relatively low. Therefore, designing the first busbar 401 and the second busbar 402 is beneficial to realizing the electrical connection between the metal conductive layer 310 and the wire segments of the wire unit 20 and can ensure the reliability of the electrical connection.

[0154] In a possible embodiment, please refer to Figure 4 、 Figure 8 and Figure 9 , the metal conductive layer 310 includes a first conductive edge 3101 and a second conductive edge 3102 that are oppositely arranged. The first busbar 401 includes a first sub-busbar 410. The first sub-busbar 410 is located between the second sub-coating unit 302 and the first conductive edge 3101, is spaced from the second sub-coating unit 302, and is electrically connected to the first conductive edge 3101. The second busbar 402 includes a second sub-busbar 420. The second sub-busbar 420 is located between the second sub-coating unit 302 and the second conductive edge 3102, is spaced from the second sub-coating unit 302, and is electrically connected to the second conductive edge 3102.

[0155] In the embodiment of the present application, the first conductive edge 3101 and the second conductive edge 3102 are oppositely arranged along the length direction of the glass body 10. Of course, in other possible embodiments, the first conductive edge 3101 and the second conductive edge 3102 can also be oppositely arranged along other directions. Optionally, the shape of the metal conductive layer 310 includes but is not limited to being rectangular, square, or trapezoidal. In the embodiment of the present application, the trapezoidal metal conductive layer 310 is taken as an example.

[0156] By spacing the first sub-busbar 410 from the second sub-coating unit 302 and spacing the second sub-busbar 420 from the second sub-coating unit 302, it is possible to avoid a short circuit between the wire unit 20 and the first sub-coating unit 301 and avoid the second sub-coating unit 302 from shunting.

[0157] By arranging the first sub-busbar 410 between the second sub-coating unit 302 and the first conductive edge 3101 and electrically connecting it to the first conductive edge 3101, and arranging the second sub-busbar 420 between the second sub-coating unit 302 and the second conductive edge 3102 and electrically connecting it to the second conductive edge 3102, it is beneficial to form a current on the first sub-coating unit 301 that points from the first conductive edge 3101 to the second conductive edge 3102 or from the second conductive edge 3102 to the first conductive edge 3101. Thus, the current distribution on the first sub-coating unit 301 can be made uniform, facilitating the uniform heating of the information collection area 120.

[0158] In a possible embodiment, the metal conductive layer 310 further includes a third conductive edge 3103 connected between the first conductive edge 3101 and the second conductive edge 3102. The first busbar 401 further includes a third sub-busbar 411, which is arranged on the side of the third conductive edge 3103 facing the wire unit 20, is spaced from the third conductive edge 3103, and is electrically connected to the first wire segment 210. The second busbar 402 further includes a fourth sub-busbar 421, which is arranged on the side of the third conductive edge 3103 facing the wire unit 20 and is spaced from the third conductive edge 3103.

[0159] This application does not specifically limit the spacing distance between the third sub-busbar 411 and the third conductive edge 3103, as long as the corresponding electrical isolation can be achieved. This application does not specifically limit the spacing distance between the fourth sub-busbar 421 and the third conductive edge 3103, as long as the corresponding electrical isolation can be achieved. The spacing distance between the third sub-busbar 411 and the third conductive edge 3103 and the spacing distance between the fourth sub-busbar 421 and the third conductive edge 3103 can be the same or different.

[0160] Since the heating and defrosting areas achieved by the wire unit 20 and the first sub-coating unit 301 are different, there is usually a certain distance between the wire segments included in the wire unit 20 and the metal conductive layer 310 of the first sub-coating unit 301. Therefore, by making the first busbar 401 further include a third sub-busbar 411, it is beneficial to achieve the electrical connection between the first busbar 401 and the wire segments of the wire unit 20. By making the second busbar 402 further include a fourth sub-busbar 421, it is beneficial to achieve the electrical connection between the second busbar 402 and the wire segments of the wire unit 20. And making the third sub-busbar 411 and the third conductive edge 3103 arranged at intervals is beneficial to make the current on the first busbar 401 flow through the first sub-busbar 410 to the metal conductive layer 310, rather than flowing from the third sub-busbar 411 to the metal conductive layer 310. Similarly, making the fourth sub-busbar 421 and the third conductive edge 3103 arranged at intervals is beneficial to make the current on the second busbar 402 flow through the second sub-busbar 420 to the metal conductive layer 310, rather than flowing from the fourth sub-busbar 421 to the metal conductive layer 310. In this way, it can be ensured that the current distribution on the metal conductive layer 310 is along the direction opposite to the first conductive edge 3101 and the second conductive edge 3102, that is, it can ensure that the current distribution on the metal conductive layer 310 is uniform.

[0161] Among them, the energization voltage range of the wire unit 20 and the first sub-coating unit 301 is 40V to 56V. Optionally, the energization voltage of the wire unit 20 and the first sub-coating unit 301 is 40V, or 41V, or 42V, or 43V, or 44V, or 45V, or 46V, or 47V, or 48V, or 49V, or 50V, or 51V, or 52V, or 53V, or 54V, or 55V, or 56V. In the embodiments of the present application, taking the energization voltage of the wire unit 20 and the first sub-coating unit 301 as 48V as an example without clear description. The 48V energization voltage is the voltage of the vehicle power supply system of new energy vehicles.

[0162] In a possible embodiment, the total solar transmittance of the coating unit 30 is less than or equal to 60%. The total solar transmittance can be used to measure the heat insulation effect of the coating unit 30. The lower the total solar transmittance, the better the heat insulation effect.

[0163] Optionally, the total solar transmittance of the coating unit 30 is less than or equal to 50%; or, the total solar transmittance of the coating unit 30 is less than or equal to 45%; or, the total solar transmittance of the coating unit 30 is less than or equal to 40%.

[0164] In a possible embodiment, the sheet resistance range of the coating unit 30 is 0.5 Ω / sq to 5 Ω / sq; and / or, the power density of the coating unit 30 is greater than or equal to 4.0 W / dm².

[0165] Optionally, the sheet resistance range of the coating unit 30 is 0.5 Ω / sq to 1 Ω / sq, or 1 Ω / sq to 2 Ω / sq, or 2 Ω / sq to 3 Ω / sq, or 3 Ω / sq to 4 Ω / sq, or 4 Ω / sq to 5 Ω / sq. Exemplarily, the sheet resistance of the coating unit 30 is 0.5 Ω / sq, or 1 Ω / sq, or 2 Ω / sq, or 2.4 Ω / sq, or 3 Ω / sq, or 4 Ω / sq, or 5 Ω / sq.

[0166] Optionally, the power density of the coating unit 30 is greater than or equal to 5.0 W / dm², or the power density of the coating unit 30 is greater than or equal to 6.0 W / dm², or the power density of the coating unit 30 is greater than or equal to 7.0 W / dm², or the power density of the coating unit 30 is greater than or equal to 8.0 W / dm². Among them, the power density of the first sub - coating unit 301 and the power density of the second sub - coating unit 302 may be the same or different. In a possible embodiment, the power density of the first sub - coating unit 301 may be greater than the power density of the second sub - coating unit 302. Exemplarily, the power density of the first sub - coating unit 301 may be greater than or equal to 9 W / dm², and the power density of the second sub - coating unit 302 may be greater than or equal to 8 W / dm².

[0167] By designing the sheet resistance of the coating unit 30 and the power density of the coating unit 30, while taking into account the heat insulation effect of the coating unit 30, the heating temperature of the first sub - coating unit 301 on the information collection area 120 can be optimized, avoiding the heating temperature being too high or too low.

[0168] Further, as Figure 10 shown, Figure 10 is a cross - sectional schematic diagram of a glass component 100 provided by an embodiment of the present application. The glass component 100 further includes a light - shielding unit 50. The orthographic projection of the light - shielding unit 50 on the surface of the glass body 10 covers the first area 101, and the light - shielding unit 50 is used to shield the wire unit 20.

[0169] It can be understood that in this embodiment, the first area 101 of the glass body 10 corresponds to the light - shielding area of the glass component 100, and the second area 102 corresponds to the light - transmitting area of the glass component 100. Among them, the material of the light - shielding unit 50 may be black ink. The light - shielding unit 50 can be directly deposited on the surface of the glass body 10.

[0170] The light-shielding unit 50 can form a protection at the edge of the glass body 10 to prevent the sealing and bonding materials of the glass assembly 100 from aging. In addition, the light-shielding unit 50 shields the wire unit 20, which can also prevent the wire segments of the wire unit 20 from being seen from the outside and affecting the appearance of the glass assembly 100.

[0171] In a possible embodiment, as Figure 11 shown, when the glass assembly 100 is under an ambient temperature of 23°C and a powered-on voltage of 48V for 30 minutes, a heating effect with a maximum temperature of 68.5°C is achieved.

[0172] As Figure 12 shown, when the glass assembly 100 is under an ambient temperature of -18°C and water is sprayed to form an ice layer with a thickness of 0.55 mm, after being powered on for 10 minutes, the defrosting ratio of the information collection area 120 can reach 92%; the defrosting ratio of the wiper rest area 110 can be 85%.

[0173] As Figure 13 shown, after continuing to be powered on for 15 minutes, the defrosting ratio of the information collection area 120 can reach 95%; the defrosting ratio of the wiper rest area 110 can be 90%.

[0174] As Figure 14 shown, after continuing to be powered on for 20 minutes, the defrosting ratio of the information collection area 120 can reach 99%; the defrosting ratio of the wiper rest area 110 can be 95%.

[0175] In a possible embodiment, the glass assembly 100 is laminated glass. In another possible embodiment, the glass body 10 is single-layer glass. This embodiment takes the glass body 10 as laminated glass as an example.

[0176] Please refer to Figure 15 and Figure 16 , Figure 15 which is a schematic structural diagram of the laminated glass provided by the embodiment of the present application, Figure 16 and this is another schematic structural diagram of the laminated glass provided by the embodiment of the present application. The laminated glass includes a first glass plate 60, an adhesive layer 70, and a second glass plate 80. One of the first glass plate 60 and the second glass plate 80 is the outer glass plate, and the other is the inner glass plate. The outer glass plate includes a first surface and a second surface arranged opposite to each other, and the inner glass plate includes a third surface and a fourth surface arranged opposite to each other. The adhesive layer 70 connects the second surface and the third surface.

[0177] Among them, the first surface of the outer glass plate faces the outside of the vehicle, and the second surface of the outer glass plate faces the adhesive layer 70; the third surface of the inner glass plate faces the adhesive layer 70, and the fourth surface of the inner glass plate faces the inside of the vehicle.

[0178] In a possible embodiment, asFigure 15 As shown, the first glass plate 60 is an outer glass plate, and the second glass plate 80 is an inner glass plate. The wire unit 20 and the coating unit 30 are provided on the second surface of the outer glass plate.

[0179] In another possible embodiment, as Figure 16 shown, the first glass plate 60 is an inner glass plate, and the second glass plate 80 is an outer glass plate. The wire unit 20 and the coating unit 30 are provided on the third surface of the inner glass plate.

[0180] This application does not specifically limit the thickness of the first glass plate 60 and the second glass plate 80. Optionally, the thickness of the first glass plate 60 and the second glass plate 80 can be 0.7 mm to 4 mm, and the thickness of the first glass plate 60 and the second glass plate 80 can be the same or different. This application does not specifically limit the material of the bonding layer 70. Optionally, the material of the bonding layer 70 can include one or several of polycarbonate (PC), polyvinyl chloride (PVC), polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyacrylate (PA), polymethyl methacrylate (PMMA), polyurethane (PUR), ionomer film (SGP), etc. This application does not specifically limit the thickness of the bonding layer 70. Optionally, the thickness of the bonding layer 70 is less than the thickness of the glass body 10, and the thickness of the bonding layer 70 can be 0.38 mm to 2.28 mm, and specific examples can be 0.38 mm, 0.5 mm, 0.76 mm, 1.14 mm, 1.52 mm, 1.9 mm, 2.28 mm, etc. In one possible embodiment, the material of the bonding layer 70 can be PVB, and the thickness of the bonding layer 70 can be 0.76 mm. The bonding layer 70 can be rectangular or wedge-shaped.

[0181] Please refer to Figure 17 and Figure 18 ., Figure 17 is a schematic structural diagram of the glass assembly 100 without the wire unit 20 designed, Figure 18 is Figure 17 a thermal simulation schematic diagram of the glass assembly 100 shown after being energized for a period of time. As can be seen from Figure 18 , when the wire unit 20 is not designed to divide the voltage, after the first sub-coating unit 301 is energized for 20 minutes, the power reaches 783.4 W, resulting in the maximum temperature of the information collection area 120 reaching 510.4 °C. At this temperature, the bonding layer 70 undergoes softening, and thus the extrusion of the bonding layer 70 will cause uneven folds, which will cause the path of light passing through the glass assembly 100 to deflect, resulting in serious optical distortion.

[0182] In addition, the present application also provides a vehicle. The vehicle can be a sedan, a bus, a truck, a tractor, a special transport vehicle, a special vehicle, etc. In the embodiments of the present application, a sedan is taken as an example. The vehicle includes a body assembly and the glass assembly 100 described in any of the above embodiments. Of course, the vehicle may also include wheels, a chassis, an engine, etc. The glass assembly 100 is connected to the body assembly. The connection manner between the glass assembly 100 and the body assembly includes but is not limited to welding, bonding, snap connection, bolt connection, etc.

[0183] The preparation method of the glass assembly 100 includes but is not limited to the following step S10.

[0184] S10: Form a coating unit 30 on the surface of the glass body 10 by using magnetron sputtering technology.

[0185] Among them, the structure of the glass body 10 is the same as that of the glass body 10 in the glass assembly 100 in the above embodiments, and the structure of the coating unit 30 is the same as that of the coating unit 30 in the glass assembly 100 in the above embodiments, which will not be elaborated here.

[0186] Magnetron sputtering technology uses high-speed particles bombarding the surface of the target under the control of a magnetic field, so that atoms or molecules on the surface of the target are sputtered out and a thin film with certain characteristics is formed on the surface of the glass body 10. Magnetron sputtering technology is beneficial to forming a coating unit 30 with uniform, large adhesion and easy area control on the surface of the glass body 10.

[0187] In a possible embodiment, step S10 includes the following step S11.

[0188] S11: Form a partition with a distance greater than or equal to 10 μm between the first sub-coating unit 301 and the second sub-coating unit 302 of the coating unit 30 by using laser film removal technology.

[0189] Laser film removal technology focuses the laser beam on the position of the film layer to be removed on the surface of the glass body 10, heats the film layer to be removed, and makes the film layer to be removed expand and rupture in a short time and be removed. The partition distance between the first sub-coating unit 301 and the second sub-coating unit 302 includes but is not limited to 10 μm, or 12 μm, or 13 μm, or 15 μm, or 16 μm, or 18 μm, or 20 μm, or 24 μm. Laser film removal technology is beneficial to cleanly removing the film layer between the first sub-coating unit 301 and the second sub-coating unit 302, avoiding short circuit, and not easily damaging the surface of the glass body 10.

[0190] Of course, in other possible embodiments, a partition can also be formed between the first sub-coating unit 301 and the second sub-coating unit 302 by cutting.
