Description

Technical Field

[0002] At low temperatures, vehicle glass surfaces are prone to mist or frost, which can affect the line of sight of cameras and lidar sensors mounted on one side of the glass. Currently, heating wires are typically added to the glass to achieve this. Cameras and lidar sensors typically have their own signal transmission areas on the glass. The camera area typically uses silver paste, while the lidar area uses enameled wire. However, the camera area and the lidar area may partially overlap. For these overlapping areas, using either silver paste or enameled wire alone will affect the signal transmission performance of the other sensor. Summary of the Invention

DETAILED DESCRIPTION

[0045] The following are preferred implementations of the present application. It should be noted that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.

[0046] Before introducing the technical solutions provided by this application, the technical problems in related technologies are introduced in detail.

[0047] Cameras and lidar sensors are commonly installed on the inside of a vehicle's front windshield as driver assistance sensors. In cold temperatures, the glass surface is prone to fogging or frost, obstructing the camera and lidar's line of sight. Therefore, heating the glass is often necessary to defrost or defog it. Four main glass heating methods exist. The first involves heating with silver paste wire laid on or within the glass surface. This approach offers low heating costs, high reliability, and resistance to damage. The second involves heating with enameled wire laid on or within the glass surface. This approach is moderately cost-effective, but the wire diameter is relatively small, potentially causing optical diffraction. The third approach involves heating with a transparent conductive film laid on or within the glass surface. However, the technology for this is relatively undeveloped, resulting in a relatively high cost. The fourth approach involves radiant heating using a heating module. This module is located on the outside of the glass and heats the glass through thermal radiation. While this technology is relatively mature, the heating efficiency is relatively low due to the radiation-based heating method, resulting in a relatively high cost.

[0048] When a vehicle uses both lidar and a camera as sensors for assisted driving, the lidar and the camera each have their own signal transmission paths, and the area where the signal transmission path passes through the glass is the signal window area of the lidar and the camera respectively. The signal window area of the lidar usually adopts an enameled wire solution that has less impact on reflection, while the signal window area of the camera usually adopts a silver paste heating solution that has less impact on diffraction. However, in order to avoid affecting the viewing angle of the front windshield and at the same time reduce the overall volume of multiple sensors, the lidar and the camera are usually placed adjacent to each other, which results in a partial overlap between the signal window area of the lidar and the signal window area of the camera. For the overlapping area, if the silver paste heating solution is used, the reflectivity of the silver paste will affect the signal transmission of the lidar. If the enameled wire heating solution is used, the diffraction of light caused by the enameled wire will affect the signal transmission of the camera. That is, no matter which heating solution is used alone in the overlapping area, it will affect the signal transmission capability of the other sensor.

[0049] In view of this, in order to solve the above problems, this application provides a vehicle window assembly, please refer to Figures 1-9 , Figure 1 This is a schematic diagram of a vehicle window assembly in one embodiment of the present application.

[0050] The vehicle window assembly 1 provided in this embodiment is primarily used in vehicles with assisted driving functions. The vehicle window assembly 1 includes a vehicle window glass 10 and a sensor assembly 20. The vehicle window glass 10 includes a glass substrate 11 and a first heating element 12 disposed on the glass substrate 11. The sensor assembly 20 is disposed on one side of the vehicle window glass 10 and includes a first sensor 21 and a second sensor 22. The glass substrate 11 has a first window area 111, through which a first signal corresponding to the first sensor 21 passes, and a second window area 112, through which a second signal corresponding to the second sensor 22 passes. The first window area 111 and the second window area 112 partially overlap, i.e., an overlapping area 113 exists between the first window area 111 and the second window area 112. The vehicle window assembly 1 also includes a second heating element 23 disposed on one side of the vehicle window glass 10. At least a portion of the second heating element 23 is spaced apart from the glass substrate 11. The second heating element 23 is located outside the transmission path of the first and second signals, i.e., it avoids the transmission path of the optical signals from the first and second sensors 21 and 22. The first heating element 12 avoids the second window area 112 and is at least partially disposed in the first window area 111 . The first heating element 12 at least corresponds to heating the non-overlapping area of the first window area 111 , and the second heating element 23 at least corresponds to heating the second window area 112 .

[0051] The vehicle window assembly 1 includes a vehicle window glass 10 and a sensor component 20, wherein the vehicle window glass 10 is a glass substrate 11 body and a general term for a series of components integrated on the surface or inside the glass substrate 11 body. The sensor component 20 is a general term for a series of components arranged outside the glass substrate 11 and used to realize functions such as sensors. The vehicle window glass 10 includes a glass substrate 11 and a first heating element 12 arranged on the glass substrate 11. Specifically, the first heating element 12 can be arranged on the surface of the glass substrate 11 or inside the glass substrate 11. For example, when the glass substrate 11 is a laminated glass substrate 11, the glass substrate 11 is divided into three layers: an inner glass substrate 11, an interlayer, and an outer glass substrate 11. At this time, the first heating element 12 can be laid in the interlayer of the glass substrate 11, so that the first heating element 12 is arranged inside the glass substrate 11 to heat the glass substrate 11. Of course, the first heating element 12 can also be placed on the side of the inner glass substrate 11 facing away from the outer glass substrate 11, that is, on the side of the glass substrate 11 facing the interior of the vehicle, so that the first heating element 12 is placed on the entire inner surface of the glass substrate 11 to heat the glass substrate 11. Optionally, the first heating element 12 includes, but is not limited to, silver paste wire, enameled wire, transparent conductive film, etc.

[0052] The sensor assembly 20 is disposed on one side of the vehicle window glass 10, specifically, on the side of the vehicle window glass 10 facing the interior of the vehicle. The sensor assembly 20 includes a first sensor 21 and a second sensor 22. The first sensor 21 and the second sensor 22 are primarily used to transmit and receive signals. The first sensor 21 includes, but is not limited to, a camera, a lidar, etc., while the second sensor 22 includes, but is not limited to, a camera, a lidar, etc. Specifically, the first sensor 21 and the second sensor 22 are different types of sensors. The first sensor 21 is used to transmit and / or receive a first signal. The first signal can pass through the glass substrate 11. The area of the glass substrate 11 through which the first signal passes is the first window area 111 corresponding to the first sensor 21. The second sensor 22 is used to transmit and / or receive a second signal. The second signal can also pass through the glass substrate 11. The area of the glass substrate 11 through which the second signal passes is the second window area 112 corresponding to the second sensor 22. The window area can also be considered the area where the sensor's field of view (FOV) intersects with the glass substrate 11.

[0053] Part of the first window area 111 overlaps with part of the second window area 112. In other words, the first window area 111 and the second window area 112 partially overlap. That is, both the first signal and the second signal will pass through the overlapping portion of the first window area 111 and the second window area 112. The vehicle window assembly 1 also includes a second heating element 23, at least part of which is spaced apart from the glass substrate 11. In other words, the second heating element 23 is not disposed on the surface of the glass substrate 11 or inside the glass substrate 11, but is disposed outside the glass substrate 11. That is, the second heating element 23 does not heat the glass substrate 11 by direct contact with the glass substrate 11, but rather heats the glass substrate 11 through air by thermal radiation. Optionally, the second heating element 23 includes but is not limited to a heating wire, a heating plate, a heating film, an infrared heating module, and the like. In addition, the second heating element 23 is located outside the transmission path of the first signal and the second signal, that is, the second heating element 23 avoids the transmission path of the optical signals of the first sensor 21 and the second sensor 22, and the transmission path of the first signal and the second signal does not pass through the second heating element 23. Therefore, the second heating element 23 will not affect the transmission performance of the first signal or the second signal.

[0054] The first heating element 12 at least corresponds to heating the non-overlapping area of the first window area 111. In other words, at least a portion of the first heating element 12 is provided to heat the portion of the first window area 111 that does not overlap with the second window area 112. That is, the first heating element 12 is not provided within the second window area 112, and the first heating element 12 is used to heat the portion of the first window area 111 that does not overlap with the second window area 112. The second heating element 23 corresponds to the second window area 112, that is, the second heating element 23 is used to heat at least the entire area of the second window area 112, including the portion of the second window area 112 that does not overlap with the first window area 111, and the portion that overlaps with the first window area 111 and the second window area 112. Heating the second window area 112 by thermal radiation does not affect the transmission of the second signal, that is, the transmission performance of the second sensor 22 is not affected. By placing the first heating element 12 within the first window region 111 and thereby heating the non-overlapping area within the first window region 111, the signal transmission of the first sensor 21 is not affected while the first window region 111 is being heated. This also avoids placing the first heating element 12 within the second window region 112 and thereby affecting the signal transmission performance of the second sensor 22. Furthermore, the second heating element 23 is not disposed on the glass substrate 11 and is located outside the transmission range of the first and second signals, thus not affecting the signal transmission between the first and second sensors 21, 22.

[0055] Specifically, the first sensor 21 can be a camera, and the second sensor 22 can be a laser radar, then the corresponding first heating element 12 is a silver paste wire that has little impact on the camera. At this time, the area where the laser radar signal passes through the glass substrate 11 is not equipped with any heating elements, that is, the signal transmission of the laser radar will not be affected. The area where the camera passes through the glass substrate 11 uses a silver paste wire that has little impact on the camera, that is, the signal transmission of the camera will basically not be affected. Of course, the first sensor 21 can also be a laser radar, and the second sensor 22 is a camera, then the corresponding first heating element 12 is an enameled wire. At this time, the camera signal is transmitted through the second window area 112, and the second window area 112 is not equipped with any heating elements, which will not affect the camera signal transmission. The area of the glass substrate 11 through which the laser radar passes is the first window area 111, and the enameled wire solution used in the first window area 111 will not affect the laser radar signal transmission.

[0056] That is to say, this embodiment, through the combination of the first heating element 12 and the second heating element 23, not only satisfies the heating of the first window area 111 and the second window area 112 for defrosting and defrosting, but also solves the problem of the conflicting heating methods of the overlapping area 113 of the first window area 111 and the second window area 112, thereby ensuring the reliability of the heating system and reducing the cost of the heating system.

[0057] In summary, this embodiment utilizes the first heating element 12 to directly heat the non-overlapping area of the first window region 111, while the second heating element 23 radiates heat to heat the entire second window region 112. This not only satisfies the requirements for heating and defogging the first and second window regions 111, 112, but also resolves the conflicting heating methods for the overlapping region 113 of the first and second window regions 111, 112. Furthermore, while ensuring effective heating, the power and area required by the heating module are reduced, preventing sensor overheating. Furthermore, while maintaining system reliability, the cost of the heating system is reduced, thereby achieving a low-cost, high-efficiency, and low-risk heating solution for the glass substrate 11.

[0058] Optionally, when there are two first sensors 21 and one second sensor 22, the second sensor 22 can be located between the two first sensors 21 or on one side of the two first sensors 21. When the second sensor 22 is located between the two first sensors 21, there are two first window areas 111 and one second window area 112, with two overlapping areas 113. Similarly, the first heating element 12 is located in the non-overlapping area of the two first window areas 111, and the second heating element 23 corresponds to the second window area 112 and heats the second window area 112.

[0059] Optionally, the vehicle window glass 10 also includes a third heating element, which is arranged outside the first window area 111 and the second window area 112 of the glass substrate 11 and is used to heat the area of the glass substrate 11 other than the first window area 111 and the second window area 112. The third heating element can be the same as the first heating element 12 and the second heating element 23, or different.

[0060] Please refer again Figure 3-Figure 4 In this embodiment, the vehicle window assembly 1 further includes a bracket 24, which is fixedly connected to the inner surface of the glass substrate 11. The first sensor 21 and the second sensor 22 are both disposed in the bracket 24 and are spaced apart from the glass substrate 11. The second heating element 23 is disposed on the inner surface or outer surface of the bracket 24.

[0061] In addition to the aforementioned components, the vehicle window assembly 1 also includes a bracket 24, which primarily serves as a mounting base for the sensor assembly 20 and the second heating element 23. Optionally, the bracket 24 is tilted relative to the glass substrate 11. In other words, the bracket 24 is angled relative to the glass substrate 11, meaning that the bracket 24 is neither perpendicular nor parallel to the glass substrate 11. Since the glass substrate 11 is inherently tilted, this would result in an excessively large angle between the bracket 24 and the horizontal plane, thereby reducing the heating efficiency of the second heating element 23. Therefore, the bracket 24 is typically positioned horizontally. Optionally, methods for securing the bracket 24 to the glass substrate 11 include, but are not limited to, bonding or welding.

[0062] The first sensor 21 and the second sensor 22 can both be arranged in the bracket 24, that is, the first sensor 21 and the second sensor 22 are arranged inside the bracket 24, and the bracket 24 can be used to cover the first sensor 21 and the second sensor 22 for protection. In this case, the bracket 24 can also be called a cover. Optionally, the first sensor 21 and the second sensor 22 can be arranged on the inner surface of the bracket 24. As for the second heating element 23, it can also be arranged on the bracket 24, and can be arranged on the inner surface of the bracket 24 or on the outer surface of the bracket 24. In other words, the second heating element 23 can be arranged inside the bracket 24 or on the outside of the bracket 24, as long as the bracket 24 can provide a foundation for installation. As for the specific position of the second heating element 23 and the positional relationship between the sensor assembly 20 and the second heating element 23, this application will be described in detail below.

[0063] In this embodiment, a bracket 24 is added to provide a mounting base for the first sensor 21 , the second sensor 22 , and the second heating element 23 , thereby facilitating the second heating element 23 to be mounted on one side of the glass substrate 11 and spaced apart from the glass substrate 11 .

[0064] Optionally, the vehicle window glass 10 further includes an opaque printed border 13 disposed on the surface of the glass substrate 11. The printed border 13 is primarily used to conceal adhesive marks left when the bracket 24 is bonded to the glass substrate 11, thereby enhancing the aesthetics of the vehicle window assembly 1. The printed border 13 also prevents unnecessary signals from entering the sensor, thereby improving sensor accuracy.

[0065] Please refer again Figure 3-Figure 4 In this embodiment, along the horizontal direction, the second heating element 23 is closer to the glass substrate 11 than the first sensor 21 and the second sensor 22 .

[0066] As can be seen from the above description, the vehicle window assembly 1 further includes a bracket 24, on which the first sensor 21, the second sensor 22, and the second heating element 23 are all mounted. Therefore, the first sensor 21, the second sensor 22, and the second heating element 23 have a specific positional relationship. In the horizontal direction, this embodiment allows the second heating element 23 to be closer to the glass substrate 11 than the first and second sensors 21, 22. In other words, the vertical distance between the second heating element 23 and the glass substrate 11 is smaller than the vertical distances between the first and second sensors 21, 22, and the glass substrate 11. The second heating element 23 is positioned further forward, while the first and second sensors 21, 22 are positioned further back. When the first and second sensors 21, 22 are closer to the glass substrate 11, heat radiation from the second heating element 23 is directly transferred to the first and second sensors 21, 22, causing the sensor assembly 20 to overheat. In this embodiment, the second heating element 23 is closer to the glass substrate 11 than the first sensor 21 and the second sensor 22 , so that the second heating element 23 does not heat the first sensor 21 and the second sensor 22 during heating, thereby preventing the first sensor 21 and the second sensor 22 from overheating.

[0067] Please refer to Figure 10 , Figure 10This is a side view of a vehicle window assembly in another embodiment of the present application. In this embodiment, the second heating element 23 is disposed on the inner surface of the bracket 24 in the vertical direction. As can be seen from the above, the second heating element 23 is disposed on the bracket 24, and therefore, the second heating element 23, the bracket 24, and the glass substrate 11 have a certain positional relationship. Furthermore, in this embodiment, the second heating element 23 can also be disposed on the side of the bracket 24 close to the glass substrate 11 in the vertical direction. When the second heating element 23 is mounted on the bracket 24, there are three possible mounting methods. The first is to mount the second heating element 23 on the side of the bracket 24 close to the glass substrate 11, i.e., on the inner surface of the bracket 24. The second is to mount the second heating element 23 on the side of the bracket 24 away from the glass substrate 11, i.e., on the outer surface of the bracket 24. The third is to mount the second heating element 23 directly inside the bracket 24, or to integrate the second heating element 23 and the bracket 24 into one body. In this embodiment, the bracket 24 is installed on the side of the bracket 24 close to the glass substrate 11, that is, the inner surface of the bracket 24, so that the second heating element 23 is installed on the basis of the bracket 24. It is closer to the glass substrate 11 and the heat radiation effect is better, thereby reducing the power required to heat the glass substrate 11, and further reducing the use cost of the second heating element 23.

[0068] Please refer again Figure 3-Figure 6 In this embodiment, the power of the second heating element 23 is 5W-30W. In this embodiment, the heating power of the second heating element 23 is controlled to be 5W-30W. When the heating power of the second heating element 23 is too small, for example, less than 5W, it cannot meet the heating requirements of the second window area 112, that is, it cannot defog or defrost. When the heating power of the second heating element 23 is too large, for example, greater than 30W, the first sensor 21 and the second sensor 22 may be overheated due to heat radiation, thereby affecting the performance of the sensors, or accelerating the aging of the glue on the glass substrate 11, increasing the risk of the bracket 24 falling off. In this embodiment, by setting the power of the second heating element 23 to 5W-30W, while meeting the heating requirements of the second window area 112, it will not cause the sensor to overheat or the glue on the glass substrate 11 to accelerate the aging due to excessive heating power. Specifically, the heating power of the second heating element 23 can be 5W, 10W, 15W, 20W, 25W, or 30W.

[0069] Please refer again Figure 3-Figure 6 In this embodiment, the area of the second window region 112 is 0.005m 2 -0.03m 2 From the above, it can be seen that the power of the second heating element 23 is 5W-30W. In this embodiment, the area of the second window area 112 can be 0.005m 2 -0.03m 2When the area of the second window region 112 is increased from 0.005m 2 Growth to 0.03m 2 When the area of the second window region 112 is too small, for example, less than 0.005 m 2 When the angle between the glass substrate 11 and the bracket 24 is too large, the wind resistance coefficient of the vehicle 2 is increased. At the same time, the reflection of the glass substrate 11 is easily projected onto the road ahead, which can easily cause the driver to misjudge and cause risks. When the area of the second window area 112 is too large, for example, greater than 0.03m 2 When the area to be heated by radiation is too large, the power of the second heating element 23 will be too large, which will cause the sensor assembly 20 to overheat or accelerate the aging of the adhesive on the glass substrate 11, increasing the risk of the bracket 24 falling off. In this embodiment, the area of the second window area 112 is limited to 0.005m 2 -0.03m 2 , so that the area of the second window area 112 is neither too small, causing the reflection of the glass substrate 11 to affect the driver's driving, nor too large, causing the power of the second heating element 23 to increase accordingly, thereby improving the user experience. Specifically, the area of the second window area 112 can be 0.005m 2 , 0.01m 2 , 0.015m 2 , 0.02m 2 , 0.025m 2 , 0.03m 2 .

[0070] Please refer again Figure 3-Figure 6 In this embodiment, the angle between the glass substrate 11 and the horizontal plane (such as Figure 3 ∠A in the figure) is 15°-40°. Generally speaking, when the window assembly 1 is installed on the body 3 of the vehicle 2, the bracket 24 is horizontal to the ground, so the angle between the glass substrate 11 and the bracket 24 is 15°-40°, that is, the angle between the glass substrate 11 and the horizontal ground is 15°-40°. When the angle between the glass substrate 11 and the horizontal plane is too small, for example, less than 15°, when the distance between the glass substrate 11 and the sensor remains unchanged, the area of the second window area 112 is too large, which causes the power of the second heating element 23 to increase accordingly, which can easily cause the sensor to overheat or the glass substrate 11 glue to age faster. When the angle between the glass substrate 11 and the horizontal plane is too large, for example, greater than 40°, the reflective image of the glass substrate 11 is easily projected onto the road ahead, which can cause the driver to misjudge and cause risks. In addition, the excessive inclination angle of the glass substrate 11 will also affect the overall drag coefficient of the vehicle 2.

[0071] In this embodiment, the angle between the glass substrate 11 and the bracket 24 is limited to 15°-40°, so that the angle is neither too small to cause excessive power of the second heating element 23, nor too large to cause the hidden danger of reflection projection of the glass substrate 11, thereby further improving the user experience.

[0072] Specifically, the angle between the glass substrate 11 and the bracket 24 can be 15°, 20°, 25°, 30°, 35°, or 40°.

[0073] Please refer again Figure 4 In this embodiment, the second heating element 23 includes a first end 231 and a second end 232 that are oppositely arranged in the horizontal direction. The vertical distance between the first end 231 and the glass substrate 11 is smaller than the vertical distance between the second end 232 and the glass substrate 11, and the heat generated by the second end 232 is greater than the heat generated by the first end 231.

[0074] As can be seen from the above, the second heating element 23 is disposed on one side of the glass substrate 11, and the second heating element 23 is disposed at an angle to the glass substrate 11. In this embodiment, the second heating element 23 includes a first end 231 and a second end 232 disposed opposite each other along a direction perpendicular to the thickness of the second heating element 23. That is, along the horizontal direction, the second heating element 23 includes a first end 231 and a second end 232 disposed opposite each other. The vertical distance from the first end 231 to the glass substrate 11 is less than the vertical distance from the second end 232 to the glass substrate 11. In other words, the second heating element 23 has a first end 231 that is closer to the glass substrate 11 and a second end 232 that is farther away from the glass substrate 11. In other words, the left end of the second heating element 23 is the first end 231, and the right end is the second end 232. The heat generated by the second end 232 is greater than the heat generated by the first end 231, that is, the second end 232 farther away from the glass substrate 11 generates more heat than the first end 231 closer to the glass substrate 11, thereby making the second window area 112 heated more evenly, and the second heating element 23 has a better heating effect on the second window area 112.

[0075] In order to achieve that the second end 232 of the second heating element 23 generates a higher amount of heat than the first end 231 , the present application provides two specific implementations, which will be described in detail below.

[0076] Please refer to Figure 11 , Figure 11This is a top view of a vehicle window assembly in another embodiment of the present application. In one embodiment, the length of the first end 231 is less than the length of the second end 232. That is, under the premise that the heating power of the first end 231 and the second end 232 is the same, the heating area of the second end 232 is larger than the heating area of the first end 231, so that the second end 232 generates more heat than the first end 231. By making the length of the second end 232 greater than the length of the second end 232, the heating value of the second end 232 is greater than the heating value of the first end 231, thereby reducing the difficulty of setting the second heating element 23 to uniformly heat the second window area 112.

[0077] Please refer again Figure 4 In another embodiment, the heating power of the first end 231 is less than the heating power of the second end 232. That is, assuming the heating areas of the first and second ends 231 and 232 are the same, the heating power of the second end 232 is greater than that of the first end 231. Consequently, within the same timeframe, the heat generated by the second end 232 is greater than that of the first end 231. By ensuring that the heating power of the second end 232 is greater than that of the first end 231, and thus the heat generated by the second end 232 is greater than that of the first end 231, the difficulty of ensuring that the second heating element 23 uniformly heats the second window is reduced.

[0078] Please refer again Figure 3-Figure 6 In this embodiment, the first heating element 12 is laid in the non-overlapping area of the first window area 111, and is used to heat the non-overlapping area of the first window area 111. When the first sensor 21 is a camera, correspondingly, the first heating element 12 is a silver paste line. When the wire diameter of the first heating element 12 is too thin, for example, less than 0.3mm, the risk of the first heating element 12 breaking is increased. At the same time, when the first heating element 12 is too thin, it may cause poor heating effect. When the wire diameter of the first heating element 12 is too thick, for example, greater than 0.6mm, it may affect the signal transmission of the camera. In this embodiment, the wire diameter of the first heating element 12 is 0.3mm-0.6mm, so that the first heating element 12 is neither too thin to increase the risk of breaking, nor too thick to affect the signal transmission of the camera. Specifically, when the first heating element 12 is a silver paste line, the wire diameter of the first heating element 12 can be 0.3mm, 0.4mm, 0.5mm, or 0.6mm.

[0079] Of course, in other embodiments, the first sensor 21 can also be a laser radar. Correspondingly, the first heating element 12 is an enameled wire, and the wire diameter of the first heating element 12 is 0.05mm-0.2mm. When the wire diameter of the first heating element 12 is too thin, for example, less than 0.05mm, the risk of the first heating element 12 breaking is increased. At the same time, the first heating element 12 being too thin will cause the first heating element 12 to have a poor heating effect on the first window area 111. When the wire diameter of the first heating element 12 is too thick, for example, greater than 0.2mm, it may affect the signal transmission of the laser radar. In this embodiment, by making the wire diameter of the first heating element 12 0.05mm-0.2mm, the first heating element 12 will neither be too thin to increase the risk of breaking, nor too thick to affect the signal transmission of the laser radar. Specifically, when the first heating element 12 is an enameled wire, the wire diameter of the first heating element 12 can be 0.05mm, 0.1mm, 0.15mm, or 0.2mm.

[0080] Please refer to Figure 12-16 , Figure 12 This is a front view of a vehicle in one embodiment of the present application. Figure 13 for Figure 12 An enlarged view of a portion of the vehicle is shown. Figure 14 This is a front view of a vehicle in another embodiment of the present application. Figure 15 for Figure 14 An enlarged view of a portion of the vehicle is shown. Figure 16 This is a schematic diagram of a first window area, a second window area, and an overlapping area on a glass substrate in another embodiment of the present application. In this embodiment, the vehicle window assembly 1 is mounted on a vehicle body 3, with the first sensor 21 and the second sensor 22 arranged along the height direction of the vehicle body 3, or the first sensor 21 and the second sensor 22 arranged along the width direction of the vehicle body 3.

[0081] As can be seen from the above description, the first sensor 21 and the second sensor 22 are located on the same side of the glass substrate 11, and are positioned adjacent to each other. In this embodiment, when the window assembly 1 is mounted on the vehicle body 3, the first sensor 21 and the second sensor 22 are aligned along the height of the vehicle body 3, or along the width of the vehicle body 3. When the first sensor 21 and the second sensor 22 are aligned along the height of the vehicle body 3, that is, when the first sensor 21 and the second sensor 22 are arranged longitudinally, the overlap between the first window area 111 of the first sensor 21 and the second window area 112 of the second sensor 22 is relatively small, thereby reducing the heating power of the second heater 23 and thereby reducing the risk of sensor overheating. When the first sensor 21 and the second sensor 22 are aligned along the width of the vehicle body 3, that is, when the first sensor 21 and the second sensor 22 are arranged transversely, the first sensor 21 and the second sensor 22 occupy less space in the longitudinal direction of the glass substrate 11, thereby minimizing the impact on the field of view of the front windshield substrate 11 and thereby improving the user's driving experience.

[0082] Please refer again Figure 3-Figure 6 In this embodiment, the first sensor 21 is a laser radar, the second sensor 22 is a camera, and the second sensor 22 is closer to the second heating element 23 than the first sensor 21. From the above content, it can be seen that the second heating element 23 is used to heat the second window area 112 corresponding to the second sensor 22, and the heating method of the second heating element 23 is thermal radiation heating. Correspondingly, since the second window area 112 corresponds to the second sensor 22, the second heating element 23 is used to heat the second window area 112, so the thermal radiation of the second heating element 23 to the second sensor 22 is greater than the thermal radiation to the first sensor 21. In other words, the impact of the second heating element 23 on the second sensor 22 is greater than the impact on the first sensor 21. Therefore, in this embodiment, the first sensor 21 is a laser radar and the second sensor 22 is a camera. Since the camera is less affected by temperature than the laser radar, in this embodiment, the first sensor 21 is set to be a laser radar that is more affected by temperature, and the second sensor 22 is set to be a camera that is less affected by temperature. That is to say, the laser radar that is more affected by temperature is farther away from the second heating element 23, and the camera that is less affected by temperature is closer to the second heating element 23, thereby reducing the impact of the second heating element 23 on the sensor.

[0083] Please refer again Figure 3-Figure 6 In this embodiment, when the temperature of the glass substrate 11 is lower than the preset temperature, both the first heating element 12 and the second heating element 23 are heated; when the temperature of the glass substrate 11 is not lower than the preset temperature, the first heating element 12 is heated and the second heating element 23 stops heating.

[0084] As can be seen from the above description, the first heating element 12 is used to heat the non-overlapping area of the first window area 111, and the second heating element 23 is used to heat the entire area of the second window area 112. In this embodiment, when the temperature of the glass substrate 11 is less than a preset temperature, the first heating element 12 and the second heating element 23 are heated simultaneously. When the temperature of the glass substrate 11 is not less than the preset temperature, the first heating element 12 is heated, and the second heating element 23 stops heating. In other words, when the temperature of the glass substrate 11 is relatively low, the first heating element 12 and the second heating element 23 heat the glass substrate 11 simultaneously, thereby rapidly increasing the temperature of the glass substrate 11 and accelerating defrosting and defogging. When the temperature of the glass substrate 11 reaches the preset temperature, only the temperature of the glass substrate 11 needs to be maintained to prevent fogging. In other words, only the first heating element 12, which has a high heating efficiency, is required to maintain the temperature of the glass substrate 11. The less efficient heating elements can be turned off, thereby saving energy in the vehicle 2.

[0085] In this embodiment, the first heating element 12 and the second heating element 23 heat the glass substrate 11 simultaneously when the preset temperature has not been reached. When the preset temperature is reached, the first heating element 12 heats and the second heating element 23 stops heating, thereby reducing the energy loss of the first heating element 12 and the second heating element 23.

[0086] Please refer again Figure 12 This embodiment provides a vehicle 2, which includes a vehicle body 3 and a window assembly 1 as provided in the above embodiment of the present application, and the window assembly 1 is installed on the vehicle body 3.

[0087] The vehicle 2 referred to in this embodiment is a vehicle 2 having at least two types of driver assistance sensors installed on one side of a glass substrate 11 of vehicle 2.

The first heating element 12 is used to heat the non-overlapping area of the first window region 111, while the second heating element 23, located on one side of the glass substrate 11, provides radiant heating in the second window region 112. This solves the problem of heating the glass substrate 11 when the window areas of the first sensor 21 and the second sensor 22 overlap, thereby improving the user experience.
