Abstract
Description
Technical Field
[0001] This application relates to the field of automotive technology, and more specifically to a glass assembly and a vehicle. Background Technology
[0002] The placement of sensors such as cameras and lidar within vehicles is crucial for enabling assisted driving and intelligent driving technologies. These sensors are typically located inside the vehicle's cabin, close to the windshield, allowing them to identify objects in front of the vehicle. However, when condensation or fogging on the windshield appears in the sensor's light-transmitting area, it degrades the quality of the signal acquired by the sensor.
[0003] In existing technologies, heating wires are typically printed on the windshield to generate heat for defrosting and defogging. However, these heating wires are usually evenly distributed on the windshield, with some of them positioned in the light-transmitting area of the sensor. This portion of the heating wires can obstruct the optical signal and cause diffraction, resulting in poor signal quality acquired by the sensor. Utility Model Content
[0004] In view of this, this application provides a glass assembly and a vehicle to solve the problem that the heating wires on the existing windshield glass cause obstruction and diffraction to the sensor, resulting in poor signal quality of the sensor.
[0005] This application provides a glass assembly, comprising a glass body, a first heating element, a light shield, and a second heating element. The glass body has a light-transmitting area; the light-transmitting area includes a first region for transmitting a first optical signal, which is used by a first sensor to identify obstacles. The first heating element is disposed on at least one side of the first region within the light-transmitting area. The light shield is connected to the glass body. The second heating element is disposed on the surface of the light shield and is used to heat the first region.
[0006] In this embodiment, the first heating element around the first area can heat the first area by thermal radiation, and the second heating element can also heat the first area by thermal radiation. Thus, by heating the first area together with the first heating element and the second heating element, the heating effect of the first area and the heating effect of the area outside the first area in the light-transmitting area can be more balanced, thereby achieving a more balanced defrosting and defogging effect on the first area and the defrosting and defogging effect on the area outside the first area in the light-transmitting area.
[0007] In one possible implementation, the first heating element is a heating wire, which can be printed onto the light-transmitting area using processes such as screen printing, facilitating its placement on the glass body. And / or, the second heating element is a heating film, which may include resistors and a protective layer. Multiple resistors can be distributed on the surface of the light-shielding cover in series or parallel, with the distribution area corresponding to the first area. When the resistors are energized, their heat is transferred to the first area via thermal radiation, thus heating the first area. The protective layer can be foam, covering the surface of the resistors to protect them and also act as a buffer. This foam can be thermally insulating foam to prevent heat from the resistors from transferring away from the first area, allowing more heat to be transferred to the first area.
[0008] In one possible implementation, the orthographic projection of the second heating element onto the glass body at least partially coincides with the first region. Here, the orthographic projection of the second heating element onto the glass body refers to its projection along the thickness direction of the glass body. This allows the heat from the second heating element to be radiated more concentratedly to the first region, improving the heating efficiency of the first region.
[0009] In one possible implementation, the light shield includes a base plate and side plates, which enclose an installation space where the sensor is mounted. The side plates and the base plate are connected to the glass body. The second heating element is disposed on the surface of the base plate. The area of the base plate's orthographic projection on the glass body is larger than the area of the side plates' orthographic projection on the glass body. By mounting the second heating element on the surface of the base plate, the orthographic projection of the second heating element on the glass body can have a larger area that overlaps with the first region, thereby improving the heating efficiency of the first region.
[0010] In one possible implementation, the second heating element is disposed on the side of the base plate facing away from the mounting space. Since the mounting space needs to accommodate components such as sensors and transmission lines, it is inconvenient to install the second heating element on the surface of the mounting space inside the light shield. However, the side of the base plate facing away from the mounting space has a larger mounting space, which facilitates the connection between the second heating element and the light shield. Therefore, disposing the second heating element on the side of the base plate facing away from the mounting space facilitates operation.
[0011] In one possible implementation, the first heating element is located on the surface of the glass body. For example, the first heating element can be disposed on the surface of the glass body facing the vehicle's cockpit. Exemplarily, the first heating element can be a heating wire, which can be made of conductive silver paste or a similar material. The heating wire pattern is directly printed onto the surface of the glass body using high-precision screen printing technology. After printing, the glass body is sintered at high temperature, allowing the conductive paste to bond with the glass body to form a single, continuous heating wire. Alternatively, the first heating element can be disposed inside the glass body. For example, the first heating element can be an extremely fine tungsten or copper wire, etc. The glass body includes a first glass sheet and a second glass sheet. The extremely fine tungsten or copper wires can be arranged in a designed pattern between the first and second glass sheets, and the wires can be fixed using a laminated glass process, thus placing the wires inside the glass body.
[0012] In one possible implementation, the first heating element and the second heating element are connected in parallel to the power supply circuit, so that the power supply circuit can control the first heating element and the second heating element to heat up or stop heating synchronously. Therefore, a single power supply circuit can simultaneously control the heating and stopping of both the first and second heating elements, making the control logic of the power supply circuit applicable to both heating elements. This achieves control logic normalization, avoids the complexity of the overall vehicle control logic caused by independent control of the first and second heating elements, and simplifies the structure.
[0013] Secondly, this application also provides a vehicle, including a body, wherein the vehicle further includes the glass assembly provided in the first aspect of this application; the glass assembly is mounted on the body. The vehicle including the glass assembly provided in the first aspect of this application has similar technical effects to the aforementioned glass assembly, and will not be described in detail here.
[0014] In one possible implementation, the vehicle also includes a housing that covers the outside of the sunshade. The housing can protect the sunshade and the second heating element. The housing can also integrate components such as an interior rearview mirror to improve integration.
[0015] In one possible implementation, the first heating element is located on the surface of the glass body facing the driver's cabin of the vehicle, thereby preventing the heating wire from being exposed to the outside of the vehicle and affected by the environment, temperature, etc.

[0038] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0039] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0040] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0041] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0042] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0043] Figure 1 This is a schematic diagram of vehicle glass in a related technology, such as... Figure 1As shown, the sensor 20 in the vehicle can detect obstacles outside the vehicle through the vehicle glass 10, such as the windshield at the front of the vehicle. The sensor 20 can detect obstacles in front of the vehicle through the windshield. The sensor 20 can be a camera, a radar, or a LiDAR sensor, all of which have obstacle detection capabilities. For example, when the sensor 20 is a camera, the camera can obtain an image of the area in front of the vehicle through the windshield, and can determine obstacles in front of the vehicle based on the image. For example, when the sensor 20 is a radar, it can use radio waves for detection; when the sensor 20 is a LiDAR, it can use laser light for detection. Both radar and LiDAR can determine obstacles in front of the vehicle based on the emitted and received light signals.
[0044] For ease of explanation, the area on the vehicle glass 10 used for detection by the sensor 20 is defined as the light-transmitting area 101. There may be multiple sensors 20, and all of them can detect external obstacles through the light-transmitting area 101.
[0045] However, when there is a large temperature difference between the outside and inside of the vehicle, water vapor or condensation can easily form on the vehicle glass 10. When water vapor or condensation covers the area (light-transmitting area 101) on the vehicle glass 10 opposite to the sensor 20, it can obstruct the detection range of the sensor 20, leading to larger detection errors or even failure of the sensor 20. For example, when the sensor 20 is a camera, the image of the exterior of the vehicle acquired by the camera will have poor clarity. Furthermore, when the sensor 20 is a radio detection radar or lidar, the radio detection radar or lidar is prone to signal loss and other problems.
[0046] Figure 2 This is a schematic diagram of vehicle glass in another related technology, such as... Figure 2 As shown, in order to remove water mist or condensation from the light-transmitting area 101 of the vehicle glass 10, a heating wire 30 can be printed in the light-transmitting area 101. The heating wire 30 generates heat after being energized, and the water mist or condensation evaporates due to the heat, thereby achieving the effect of defogging and defrosting.
[0047] Figure 3 for Figure 2 The magnified image of the light-transmitting area, as shown below. Figure 3As shown, the heating wires 30 are typically evenly distributed across the light-transmitting area 101 to ensure a nearly uniform defrosting and defogging effect across the entire area. However, in this distribution, some of the heating wires 30 fall within the detection range of the sensor 20. While this provides good defrosting and defogging for the light-transmitting area 101, the heating wires 30 within the detection range of the sensor 20 can negatively impact the detection capabilities of certain types of sensors. For example, for telephoto cameras, heating wires 30 located within the field of view (FOV) of the telephoto camera will appear in the image, affecting obstacle recognition and potentially causing phenomena such as diffraction or glare.
[0048] to this end, Figure 4 In the illustrated embodiment, no heating wire is arranged within the detection range of the corresponding sensor 20.
[0049] Figure 4 This is a schematic diagram of the structure of a glass assembly provided in one embodiment of this application, as shown below. Figure 4 As shown, the glass assembly includes a glass body 1, which includes a light-transmitting area 11 through which the sensor 20 can detect obstacles. The light-transmitting area 11 includes a first region 111 in which no heating wire is arranged. For example, when the sensor 20 is a telephoto camera, the field of view of the telephoto camera corresponds to the range of the light-transmitting area 11, which is the first region 111.
[0050] Figure 5 for Figure 4 A magnified view of the illuminated area, such as Figure 5As shown, no heating wire is arranged in the first region 111. Therefore, water mist or condensation in the first region 111 can only be removed by the heat radiated by the heating wires 30 surrounding the first region 111. In the light-transmitting area 11, the area with heating wires 30 can remove water mist or condensation through heat conduction by the heating wires 30, achieving a good removal effect. However, for the first region 111, which lacks heating wires, heating can only be achieved through the heat radiation of the heating wires 30 surrounding the first region 111. The farther away from the heating wires 30 within the first region 111, the less heat is radiated by the heating wires 30, resulting in a poorer defrosting and defogging effect. While the heating power of the heating wires 30 is sufficient to achieve a good defrosting and defogging effect in the area surrounding the first region 111, the heating wires 30 are insufficient to meet the defrosting and defogging requirements of the first region 111 itself. However, if the heating power of the heating wire 30 is increased so that the heating wire 30 around the first region 111 can effectively remove the frost and fog in the first region 111 through thermal radiation, the heating wire 30 will overheat the area around the first region 111, wasting energy. Therefore, it is difficult to achieve a nearly uniform heating effect on the first region 111 and the area around the first region 111.
[0051] Figure 6 This is a schematic diagram of the structure of a glass assembly provided in another embodiment of this application, as shown below. Figure 6 As shown in the illustration, this application provides a glass assembly that can be used in vehicles. For example, the glass assembly can be a windshield of a vehicle, which includes a body, and the windshield can be mounted on the vehicle body. The windshield can be a front windshield, i.e., the glass at the front of the vehicle. The windshield can also be a rear windshield, i.e., the glass at the rear of the vehicle. This glass assembly can also be used in other scenarios where sensors need to detect obstacles through the glass, such as in transport robots and industrial equipment.
[0052] This embodiment uses the application of a glass assembly in a vehicle as an example. The vehicle contains sensors that can detect obstacles outside the vehicle. As explained earlier, these sensors can be cameras, radar, or LiDAR, etc., sensors with obstacle detection capabilities. One sensor can be used, or two or more can be used in combination to improve the accuracy of obstacle detection. For example, two sensors can be used, namely a camera and a LiDAR, and both sensors can detect obstacles through the light-transmitting area 11. For example, three sensors can be used, namely a camera, radar, or LiDAR, and these three sensors can be used in combination to improve detection accuracy and reliability. All three sensors can detect obstacles through the light-transmitting area 11.
[0053] The glass assembly includes a glass body 1, which is light-transmitting. The glass body 1 can be a single layer of glass or a composite of multiple layers of glass. A light-transmitting area 11 is provided on the glass body 1, which transmits optical signals. These optical signals are used by sensors to identify obstacles. For example, when the sensor is a camera, the camera can receive light reflected from the obstacle in the form of an optical signal and process the optical signal into an image. When the sensor is a radio-detection radar or lidar, the radar can emit a light signal towards the obstacle (this is the transmitted signal) and can receive the light signal reflected back from the object (this is the received signal). The radar can determine the location of the obstacle based on the transmitted and received signals. In this embodiment, one or more sensors can identify obstacles through the light-transmitting area 11.
[0054] A first heating element 2 can be arranged within the light-transmitting area 11. The first heating element 2 can heat the light-transmitting area 11 to remove water mist or condensation within it. In one embodiment, the first heating element 2 is a heating wire, which can be printed into the light-transmitting area 11 using processes such as screen printing. The light-transmitting area 11 includes a first region 111, the area of which is smaller than the light-transmitting area 11; that is, the first region 111 is a portion of the light-transmitting area 11.
[0055] The first region 111 is used to transmit a first optical signal, which is used by the first sensor 201 to identify obstacles. Figure 6 In the illustrated embodiment, a projection of a sensor is formed in the first region 111, which is schematically represented as the first sensor 201. For example, the first sensor 201 is a telephoto camera.
[0056] The first sensor 201 must not be blocked by the heating wire within its detection range, and the signal received and / or emitted by the first sensor 201 is a first optical signal.
[0057] The first heating element 2 is disposed on at least one side of the first region 111 within the light-transmitting area 11, that is, the first heating element 2 is not disposed within the first region 111. At least a portion of the first heating element 2 is located around and close to the first region 111, so that the first heating element 2 can heat the first region 111 through thermal radiation to remove water vapor or condensation within the first region 111. Taking the application of glass components in a vehicle as an example, the vehicle has a length direction, a width direction, and a height direction. That is, when the vehicle is stopped on a horizontal ground, the left-right direction of the vehicle body is the width direction, the front-back direction is the length direction, and the up-down direction is the height direction.
[0058] When the glass body 1 is installed on a vehicle, its width direction X1 is consistent with the width direction of the vehicle, and its height direction Z1 is consistent with the height direction of the vehicle. Specifically, the width direction of the first region 111 is consistent with the width direction X1 of the glass body 1, and its height direction is consistent with the height direction Z1 of the glass body 1. First heating elements 2 can be distributed on one or both sides of the first region 111 in the width direction X1, or on one or both sides of the first region 111 in the height direction Z1, or on both sides of the first region 111 in both the width direction X1 and the height direction Z1. When the first heating elements 2 are distributed around the first region 111, the first region 111 can be heated from all sides, which helps to improve heating efficiency and heating uniformity.
[0059] Figure 7 A side view of the glass assembly provided in an embodiment of this application, as shown below. Figure 7 As shown, the glass assembly also includes a light shield 4 and a second heating element 3. The light shield 4 is connected to the glass body 1, and the second heating element 3 is disposed on the surface of the light shield 4 for heating the first region 111. The light shield 4 has an installation space 43 for mounting a sensor. The sensor 20 can be pre-installed in the light shield 4, and then the light shield 4 with the sensor 20 installed can be fixed to the glass body 1 as a whole. In some embodiments, the light shield 4 has a through hole or clearance notch, allowing the light shield 4 to be fixed to the glass body 1 first, and then the sensor 20 to be installed into the light shield 4 through the through hole or clearance notch. The light shield 4 can be fixed to the glass body 1 by adhesive, snap-fit, threaded connection, or other methods.
[0060] The second heating element 3 can be fixed to the surface of the light shield 4 by means of bonding, snapping, etc. The second heating element 3 does not need to be in contact with the first area 111. The second heating element 3 can heat the first area 111 by thermal radiation to improve the heating efficiency of the first area 111.
[0061] In this embodiment, the first heating element 2 around the first region 111 can heat the first region 111 by thermal radiation, and the second heating element 3 can also heat the first region 111 by thermal radiation. Thus, by heating the first region 111 together by the first heating element 2 and the second heating element 3, the heating effect of the first region 111 and the heating effect of the area outside the first region 111 in the light transmission area 11 can be more balanced, thereby achieving a more balanced defrosting and defogging effect on the first region 111 and the defrosting and defogging effect on the area outside the first region 111 in the light transmission area 11.
[0062] In one embodiment, the vehicle may include a cover that covers the outside of the sunshade 4. The cover can provide protection for the sunshade 4 and the second heating element 3. The cover may also integrate components such as an interior rearview mirror to improve the integration level.
[0063] Figure 8 for Figure 6 The enlarged view in the light-transmitting area 11 shows the glass assembly when used in a vehicle. Figure 8 The perspective is that of someone looking out from inside the vehicle's cockpit. For example... Figure 8 As shown, the second heating element 3 can be a heating film, which may include resistors and a protective layer. Multiple resistors can be distributed on the surface of the light shield 4 in series or parallel. The distribution area of the multiple resistors can correspond to the first region 111. When the resistor is energized, its heat can be transferred to the first region 111 through thermal radiation, thereby heating the first region 111. The protective layer can be foam, which covers the surface of the resistor to protect it and also acts as a buffer. This foam can be heat-insulating foam to prevent heat from the resistor from transferring away from the first region 111, allowing more heat to be transferred to the first region 111.
[0064] In one embodiment, such as Figure 8 As shown, the orthographic projection of the second heating element 3 onto the glass body 1 at least partially coincides with that of the first region 111. Specifically, the orthographic projection of the second heating element 3 onto the glass body 1 refers to the projection of the second heating element 3 onto the glass body 1 along its thickness direction. This allows the heat from the second heating element 3 to be radiated more concentratedly to the first region 111, improving the heating efficiency of the first region 111.
[0065] Figure 9 This is a schematic diagram of the structure of the glass assembly provided in this application, showing the cooperation between the light shield and the second heating element. Figure 9 As shown, the light shield 4 includes a base plate 41 and a side plate 42, which together form an installation space 43 in which the sensor can be installed. The side plate 42 and the base plate 41 are connected to the glass body 1, for example, by adhesive, snap-fit, or threaded connection. The second heating element 3 can be disposed on the surface of the base plate 41. The area of the orthographic projection of the base plate 41 onto the glass body 1 is larger than the area of the orthographic projection of the side plate 42 onto the glass body 1. By mounting the second heating element 3 on the surface of the base plate 41, the orthographic projection of the second heating element 3 onto the glass body 1 can have a larger area that coincides with the first region 111, thereby improving the heating efficiency of the first region 111.
[0066] like Figure 9As shown, the second heating element 3 is disposed on the side of the base plate 41 facing away from the mounting space 43. Since the mounting space 43 needs to accommodate components such as sensors and transmission lines, it is inconvenient to install the second heating element 3 on the surface inside the light shield 4 located within the mounting space 43. However, the side of the base plate 41 facing away from the mounting space 43 has a larger installation space, which facilitates the connection between the second heating element 3 and the light shield 4. Therefore, placing the second heating element 3 on the side of the base plate 41 facing away from the mounting space 43 facilitates operation.
[0067] In some other embodiments, if there is sufficient space within the mounting space 43 for mounting the second heating element 3, the second heating element 3 may also be disposed within the light shield 4 on a surface located within the mounting space 43, such as the inner surface of the base plate 41 or the inner surface of the side plate 42.
[0068] Figure 10 This is a side view of the glass body and the first heating element in a glass assembly provided in one embodiment of this application, as shown. Figure 10 As shown, the glass body 1 can be a single-layer glass sheet, and the first heating element 2 can be disposed on the surface of the glass body 1. For example, the first heating element 2 can be disposed on the surface of the glass body 1 facing the vehicle's driver's compartment. Exemplarily, the first heating element 2 can be a heating wire, which can be made of conductive silver paste or similar materials. The heating wire pattern is directly printed onto the surface of the glass body 1 using high-precision screen printing technology. After printing, the glass body 1 is sintered at high temperature to bond the conductive paste with the glass body 1, forming a continuous, integrally molded heating wire.
[0069] Figure 11 A side view of the glass body mating with the first heating element in a glass assembly provided in another embodiment of this application, as shown below. Figure 11 As shown, the first heating element 2 is disposed inside the glass body 1. For example, the first heating element 2 can be a very fine tungsten wire or copper wire or other metal wire. The glass body 1 includes a first glass sheet 1a and a second glass sheet 1b. The very fine tungsten wire or copper wire or other metal wire can be arranged between the first glass sheet 1a and the second glass sheet 1b according to the design pattern. The metal wire is fixed by the laminated glass process so that the metal wire is disposed inside the glass body 1.
[0070] pass Figure 10 and Figure 11 The schemes shown for cooperating the glass body 1 and the first heating element 2 can all ensure that the first heating element 2 is reliably placed on the glass body 1.
[0071] Figure 12 The control principle diagram of the glass assembly provided in the embodiments of this application is as follows: Figure 12As shown, the first heating element 2 and the second heating element 3 are connected in parallel to the power supply circuit, so that the power supply circuit can control the first heating element 2 and the second heating element 3 to heat up or stop heating synchronously. For example, line a is connected to the positive terminal of the power supply circuit, and line b is connected to the negative terminal of the power supply circuit; lines a and b constitute the power supply circuit for the first heating element 2. Line c is connected to the positive terminal of the power supply circuit, and line d is connected to the negative terminal of the power supply circuit; lines c and d constitute the power supply circuit for the second heating element 3. Since lines a and c are connected in parallel, and lines b and d are connected in parallel, the heating and stopping of the first heating element 2 and the second heating element 3 can be controlled simultaneously by a single power supply circuit. This allows the control logic of the power supply circuit to be applied to both the first heating element 2 and the second heating element 3, achieving control logic normalization. This avoids the complexity of the overall vehicle control logic caused by the independent control of the first heating element 2 and the second heating element 3, and also simplifies the structure.
[0072] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
