Description

Window assembly and vehicle

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 13, 2023, with application number 202311511218.9 and application name “Window Assembly and Vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of vehicle technology, in particular to a vehicle window assembly and a vehicle. Background Art

[0003] With the development of autonomous driving, Advanced Driving Assistance Systems (ADAS) are becoming increasingly important. ADAS uses cameras to capture road image information, which is then processed by the vehicle's computer system based on algorithms. Therefore, obtaining accurate and reliable image information is particularly important.

[0004] Vehicle windows may produce moisture, fog, frost, and other impediments, hindering image acquisition and, consequently, ADAS performance. Prior art uses heating wires to heat the signal-transmitting area of ​​the window glass to remove moisture, fog, and frost. However, these heating wires currently span the entire signal-transmitting area. For binocular or multi-lens cameras, these heating wires can affect the optical signal transmission from the wide-angle lens. This physically blocks the optical signal from the wide-angle lens, preventing light from entering the camera and, consequently, affecting the vehicle's processing and interpretation of image information. Furthermore, in nighttime scenes, the heating wires reflect light, transforming the light points captured by the camera into beams of light, affecting the accuracy of the image information captured by the camera.

[0005] Summary of the Invention

[0006] The purpose of this application is to provide a vehicle window assembly and a vehicle to reduce the physical obstruction of the wide-angle lens in the camera by the heating wire and improve the accuracy of the image information obtained by the camera.

[0007] One aspect of the present invention relates to a vehicle window assembly comprising a glass panel, a heating element, and a sensor:

[0008] The sensor is arranged on the inner side of the glass plate, and the sensor includes at least one first sensor and at least one second sensor, and the first sensor and the second sensor are arranged at intervals;

[0009] The glass plate includes a first signal-transmitting area and a second signal-transmitting area, wherein the first signal-transmitting area is an area on the glass plate where the first sensor transmits a signal, and the second signal-transmitting area is an area on the glass plate where the second sensor transmits a signal, and the first signal-transmitting area is at least partially located inside the second signal-transmitting area;

[0010] The heating element includes at least one heating wire, which avoids the first signal transmission area and is at least partially disposed in the second signal transmission area.

[0011] As can be understood, since the heating wires are positioned away from the first signal transmission area, when the first sensor acquires image information, they prevent physical obstruction of light from entering the first sensor, allowing the first sensor to obtain complete image information. This also prevents reflections from the heating wires, which could affect the accuracy of the image information acquired by the first sensor. Furthermore, the heating wires are partially positioned within the second signal transmission area, ensuring that the heating wires effectively heat the second signal transmission area, thereby enabling the heating wires to remove moisture, defogging, or defrosting the glass sheet.

[0022] In a possible implementation manner, the second section is linear and extends along the length direction of the glass sheet;

[0023] The connecting sections of the two heating section groups are respectively arranged along the partial edges of the first signal transmission area on opposite sides in the length direction, and the second section is arranged along the partial edge of one end of the first signal transmission area in the width direction.

[0024] In one possible implementation, the second segment is zigzag-shaped, and includes a plurality of third sub-segments and a plurality of series-connected segments, and two adjacent third sub-segments are electrically connected via one of the series-connected segments.

[0025] The outer two third sub-segments of the plurality of third sub-segments are respectively electrically connected to the first free ends of the two heating segment groups, the second segment is arranged along the partial edge of one end of the first signal transmission area in the width direction, and the connecting segments of the two heating segment groups are respectively arranged along the partial edges of the first signal transmission area on the opposite sides in the length direction.

[0026] In one possible implementation, each of the third segments includes a straight segment and a bent segment, and the straight segment and the bent segment are connected to each other, the free ends of the two straight segments are respectively electrically connected to the second free ends of the two heating segment groups, and the free ends of the two bent segments are respectively electrically connected to the two heating electrodes;

[0027] The two straight line segments are arranged along a portion of an edge of the first signal-transmitting area located at the other end in the width direction.

[0028] In a possible implementation manner, along the width direction of the glass sheet, a distance between two adjacent first sub-segment groups in each heating segment group is 5 mm-50 mm.

[0029] In one possible embodiment, along the width direction of the glass sheet, each first sub-segment group includes two first sub-segments and a transition segment, the two first sub-segments extend along the length direction of the glass sheet, and along the length direction of the glass sheet, the transition segment connects mutually adjacent ends of the two first sub-segments;

[0044] The beneficial effects of the present application are as follows: the first signal transmission area is at least partially located inside the second signal transmission area.

At the same time, the heating wire can be prevented from reflecting light, thereby avoiding affecting the accuracy of the optical information acquired by the first sensor. The heating wire is partially distributed inside the second signal transmission area, thereby ensuring the heating effect of the heating wire on the second signal transmission area, thereby enabling the heating wire to dewater, defog or defrost the glass plate. The heating wire is disposed along part of the periphery of the first signal transmission area, thereby enabling the heat generated by the heating wire to be quickly transferred through the glass plate to the first signal transmission area, thereby ensuring the heating effect of the first signal transmission area.

[0054] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0055] The present application provides a vehicle window assembly 100, please refer to Figures 1 to 7. The vehicle window assembly 100 includes a glass plate 30, a sensor 20 and a heating element 10. The sensor 20 is arranged on the inner side of the glass plate 30. The sensor 20 includes a first sensor 21 and a second sensor 22, and the first sensor 21 and the second sensor 22 are arranged at intervals. The glass plate 30 includes a first signal transmission area A and a second signal transmission area B. The first signal transmission area A is the signal transmission area of ​​the first sensor 21 on the glass plate 30, and the second signal transmission area B is the signal transmission area of ​​the second sensor 22 on the glass plate 30, and the first signal transmission area A is at least partially located inside the second signal transmission area B; the heating element 10 includes at least one heating wire 11, and the at least one heating wire 11 avoids the first signal transmission area A and is at least partially arranged in the second signal transmission area B.

[0056] Understandably, in inclement weather such as rain, snow, or frost, the glass plate 30 is more likely to fog or frost, preventing the sensor 20 from clearly capturing the forward field of view. Heating the glass plate 30 can accelerate the defogging and defrosting process, thereby enabling the sensor 20 to capture a clear forward field of view.

[0057] It should be noted that, in the present application, the sensor 20 at least includes an image sensor, such as a camera, which can acquire an image in front of the glass plate 30 through the first signal transmission area A and the second signal transmission area B.

[0058] In one possible embodiment, the sensor 20 is a binocular camera, one of which has a narrow-angle lens, namely, the first sensor 21; the other has a wide-angle lens, namely, the second sensor 22. In other possible embodiments, the number of sensors 20 may be two, and both sensors 20 are monocular cameras, one of which has a narrow-angle lens, namely, the first sensor 21, and the other has a wide-angle lens, namely, the second sensor 22.

[0059] In this embodiment of the present application, the first sensor 21 is a narrow-angle lens, and the second sensor 22 is a wide-angle lens. The field of view of the first sensor 21 is: FOV < 90°; the field of view of the second sensor 22 is: 90° < FOV < 180°. Optionally, the field of view of the first sensor 21 is: 20° < FOV < 40°. Optionally, the field of view of the first sensor 21 is: 40° < FOV < 90°.

[0060] According to the "near larger, far smaller" principle of sensor 20 imaging, the wider the field of view, the shorter the precisely detectable distance, and the narrower the field of view, the longer the precisely detectable distance. Because the field of view of the first sensor 21 is smaller than that of the second sensor 22, the imaging area formed by the first sensor 21 is smaller than that of the second sensor 22. It will be understood that in this embodiment, the first sensor 21 and the second sensor 22 of the sensor 20 are positioned adjacent to each other, and the field of view of the first sensor 21 is smaller than that of the second sensor 22. Therefore, the imaging area of ​​the second sensor 22 on the glass plate 30 partially includes the imaging area of ​​the first sensor 21 on the glass plate 30, that is, the first signal transmission area A is partially located within the second signal transmission area B. Preferably, in this application, at least two-thirds of the first signal transmission area A is located within the second signal transmission area B.

[0061] In the present application, the first signal-transmitting region A is at least partially located within the second signal-transmitting region B. Since the heating wire 11 is arranged away from the first signal-transmitting region A, when the first sensor 21 acquires optical information, the heating wire 11 is prevented from physically blocking light from entering the first sensor 21, thereby facilitating the first sensor 21 to obtain complete optical information. This also prevents reflections from the heating wire 11, thereby preventing the accuracy of the optical information acquired by the first sensor 21 from being affected. The heating wire 11 is partially located within the second signal-transmitting region B, ensuring that the heating wire 11 effectively heats the second signal-transmitting region B, thereby enabling the heating wire 11 to dehumidify, defog, or defrost the glass sheet 30.

[0062] In one possible embodiment, as shown in Figures 4 and 5 , the first sensor 21 and the second sensor 22 in the sensor 20 are arranged horizontally with spacing therebetween. In other possible embodiments, the first sensor 21 and the second sensor 22 in the sensor 20 may also be arranged vertically with spacing therebetween, as shown in Figure 2 . It is understood that the first sensor 21 and the second sensor 22 in the sensor 20 may also be arranged with spacing therebetween in other ways, and this application is not limited thereto.

[0063] In one possible embodiment, the window assembly 100 further includes a rain sensor (not shown) and an ETC (Electronic Toll Collection) (not shown). The rain sensor is used to adjust the movement of the windshield wipers according to the amount of rain on the glass plate 30, and the ETC is used for automatic toll collection when the vehicle 1000 passes through a highway or a bridge. In this embodiment, as shown in FIG1 , a first light-transmitting area C and a second light-transmitting area D are further provided on the glass plate 30. The first light-transmitting area C is used to allow the signal of the rain sensor to pass through, and the second light-transmitting area D is used to allow the signal of the ETC to pass through. The rain sensor is mounted on the inner side of the glass plate 30 and corresponds to the position of the first light-transmitting area C of the glass plate 30. The ETC is mounted on the inner side of the glass plate 30 and corresponds to the position of the second light-transmitting area D of the glass plate 30. The rain sensor and the ETC are respectively located on opposite sides of the sensor 20 and are spaced apart from the sensor 20.

[0064] In one possible embodiment, referring again to Figures 2 and 4, the glass plate 30 may be a laminated glass comprising a first glass plate 301, an intermediate layer 302, and a second glass plate 303. The intermediate layer 302 is bonded between the first glass plate 301 and the second glass plate 303, and the heating element 10 is fixed between the first glass plate 301 and the sensor 20.

[0065] In this embodiment, the first glass plate 301 faces the outside of the vehicle 1000, and the second glass plate 303 faces the inside of the vehicle 1000. The material of the intermediate layer 302 can be selected from at least one of transparent polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyacrylate (PA), polymethyl methacrylate (PMMA), ionic intermediate layer (SGP) or polyurethane (PU), so as to avoid obstructing the sensor 20 from obtaining external environmental information through the first glass plate 301.

[0066] Specifically, the heating element 10 can be arranged on the surface of the first glass plate 301 close to the intermediate layer 302, or between the first glass plate 301 and the intermediate layer 302, or on at least one surface of the intermediate layer 302, or between the intermediate layer 302 and the second glass plate 303, or on at least one surface of the second glass plate 303.

[0067] In one possible embodiment, referring also to FIG5 , the glass plate 30 may be a single piece of glass, and the heater 10 is fixed between the glass plate 30 and the sensor 20. Specifically, the heater 10 may be disposed on the inner surface of the glass plate 30. The glass plate 30 may be tempered glass, semi-tempered glass, or ordinary glass.

[0068] In a possible embodiment, the heating wire 11 is an enameled wire or a printed silver paste wire.

[0069] When the heating wire 11 is an enameled wire, the wire diameter range of the heating wire 11 is 0.08mm-0.5mm. Preferably, the wire diameter range of the heating wire 11 is 0.08mm-0.15mm. Specifically, the wire diameter of the heating wire 11 is 0.08mm, 0.12mm, 0.15mm, 0.17mm, 0.19mm, 0.21mm, 0.23mm, 0.25mm, 0.27mm, 0.29mm, 0.31mm, 0.33mm, 0.35mm, 0.38mm, 0.41mm, 0.44mm, 0.47mm, 0.5mm, etc., which is not limited in this application.

[0070] When the heating wire 11 is a printed silver paste line, the printed silver paste line has a printing line width range of 0.1 mm to 1.0 mm, and a coating thickness of the printed silver paste line is 3 μm to 20 μm.

[0071] In one possible embodiment, the total length of the heating wire 11 is 0.8 m-5 m. Specifically, the total length of the heating wire 11 is 0.8 m, 1 m, 1.2 m, 1.4 m, 1.5 m, 1.6 m, 1.8 m, 2 m, 2.2 m, 2.4 m, 2.6 m, 2.8 m, 3 m, 3.2 m, 3.4 m, 3.6 m, 3.8 m, 4 m, 4.2 m, 4.4 m, 4.6 m, 4.8 m, 5 m, etc., which is not limited in this application.

[0072] When the heating wire 11 is an enameled wire, the total length of the enameled wire is 1.5m-5m. Specifically, when the wire diameter of the enameled wire is 0.08mm, the total length of the enameled wire is 1.5-2.5m; when the wire diameter of the enameled wire is 0.12mm, the total length of the enameled wire is 2.5-4m; when the wire diameter of the enameled wire is 0.15mm, the total length of the enameled wire is 3-5m.

[0073] When the heating wire 11 is a printed silver paste line, that is, the heating wire 11 is formed by printing silver paste, the total length of the printed silver paste line is 0.8 m-2 m.

[0074] It should be noted that in the embodiment of the present application, the first signal-transmitting area A is approximately trapezoidal, and the second signal-transmitting area B is approximately trapezoidal. In other embodiments, depending on the relative positional relationship between the glass plate 30 and the first sensor 21 and the second sensor 22, the first signal-transmitting area A and / or the second signal-transmitting area B may also be elliptical or other shapes.

[0075] In the embodiment of the present application, as shown in FIG1 , the width of the first signal-transmitting area A along the width direction of the glass plate 30 is L0, and 50 mm ≤ L0 ≤ 100 mm. Specifically, L0 can be 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 100 mm, etc. The width of the first signal-transmitting area A can be understood as the distance between the two farthest points within the first signal-transmitting area A along the width direction of the glass plate 30. The width direction of the first signal-transmitting area A coincides with the width direction of the glass plate 30, and the length direction of the first signal-transmitting area A coincides with the length direction of the glass plate 30.

[0076] It should be noted that, in the embodiments of the present application, the sensor 20 is only described as a binocular camera and the first sensor 21 and the second sensor 22 in the sensor 20 are arranged to be spaced apart in the horizontal direction.

[0077] Referring to Figure 1 , this application provides a first embodiment of a heating element 10 for a vehicle window assembly 100. In this embodiment, the heating element 10 includes a heating wire 11 and a heating electrode 12. A heating electrode 12 is connected to each end of the heating wire 11. By energizing the heating electrodes 12, current flows through the heating wire 11, generating heat.

[0078] In this embodiment, the heating wire 11 includes a first section 111, a second section 112 and a third section 113. The first section 111 is electrically connected to the second section 112, and the first section 111 is electrically connected to the heating electrode 12 through the third section 113.

[0079] The first section 111 includes two heating segment groups 111a, which are arranged opposite each other along the length of the glass sheet 30. Each heating segment group 111a includes multiple first sub-segment groups 1111 and a connecting segment 1112 connecting two adjacent first sub-segment groups 1111. The multiple first sub-segment groups 1111 within each heating segment group 111a are arranged parallel and spaced apart along the width of the glass sheet 30. Each connecting segment 1112 electrically connects the adjacent ends of two adjacent first sub-segment groups 1111. Each heating segment group 111a includes a first free end and a second free end. Specifically, the first free end and the second free end are the ends of the two outer first sub-segment groups 1111 of each heating segment group 111a that are not connected to the connecting segment 1112. The first free end is located near the bottom of the heating element 10, and the second free end is located near the top of the heating element 10. Specifically, in this embodiment, there are four first sub-segment groups 1111. The two first sub-segment groups 1111 in each heating segment group 111 a are arranged in parallel and spaced apart along the width direction of the glass plate 30 , and the ends of two adjacent first sub-segment groups 1111 in each heating segment group 111 a are electrically connected to each other via a connecting segment 1112 .

[0080] Each first sub-segment group 1111 is generally U-shaped. Each first sub-segment group 1111 includes two first sub-segments 1111a and a transition segment 1111b. The two first sub-segments 1111a extend along the length of the glass sheet 30. The transition segment 1111b connects the adjacent ends of the two first sub-segments 1111a along the length of the glass sheet 30. In other embodiments, each first sub-segment group 1111 may have other shapes, such as a wavy shape or a semicircular shape. Each first sub-segment group 1111 may also include other numbers of first sub-segments 1111a. For example, when each first sub-segment group 1111 has four first sub-segments 1111a, the first sub-segment group 1111 is generally W-shaped. The number of first sub-segments 1111a in each first sub-segment group 1111 may also be six, seven, or eight, etc., and this is not specifically limited in the present embodiment.

[0081] In this embodiment, the spacing between two adjacent first sub-segment groups 1111 within each heating segment group 111a is 5 mm to 50 mm along the width of the glass sheet 30. The spacing between two adjacent first sub-segments 1111a within each first sub-segment group 1111 is 5 mm to 50 mm along the width of the glass sheet 30. This is because the distribution density of the first sub-segment groups 1111 within each heating segment group 111a and the distribution density of the first sub-segments 1111a within each first sub-segment group 1111 affect the heating effect of the first segments 111 on the second signal-transmitting area B.

[0082] The second segment 112 includes three second subsegments 1121, each of which is linear. The three second subsegments 1121 are sequentially connected, with two connected second subsegments 1121 forming an angle. The angles between the two second subsegments 1121 on either side and the center second subsegment 1121 are approximately equal. It can be understood that the second segment 112 as a whole is roughly an isosceles triangle. In other embodiments, the second segment 112 may include other numbers of second subsegments 1121.

[0083] The third section 113 is linear, and there are two third sections 113 , which are arranged side by side along the length direction of the glass plate 30 .

[0084] In this embodiment, the number of the heating electrodes 12 is two. The heating electrodes 12 can be formed by coating with a conductive silver paste, or can be a conductive copper foil, or a conductive aluminum foil.

[0085] In this embodiment, two heating segment groups 111a are positioned opposite each other along the length of the glass sheet 30, one on each side of the second segment 112. Two third segments 113 are positioned between the two heating segment groups 111a, spaced apart. The heating wire 11 is electrically connected to the heating electrodes 12. By connecting the two heating electrodes 12 to the positive and negative terminals of a vehicle power supply, current flows through the heating wire 11, generating heat.

[0086] Specifically, the first free end of one heating segment group 111a is electrically connected to the second segment 112, and the second free end is electrically connected to one third segment 113. The first free end of another heating segment group 111a is electrically connected to the second segment 112, and the second free end is electrically connected to another third segment 113. The two outer second sub-segments 1121 of the three second sub-segments 1121 are electrically connected to the first free ends of the two heating segment groups 111a, respectively. The ends of the two third segments 113 not connected to the heating segment groups 111a are electrically connected to the two heating electrodes 12, respectively. It can be understood that the two ends of each heating segment group 111a are electrically connected to the second segment 112 and the third segment 113, respectively, so that the first segment 111, the second segment 112, and the third segment 113 are electrically connected as a whole.

[0087] In this embodiment, the heating filament 11 is located outside the first signal-transmitting area A and at least partially within the second signal-transmitting area B. The second segment 112 of the heating filament 11 is located within the second signal-transmitting area B. The second segment 112 of the heating filament 11 is positioned along a portion of the edge of the first signal-transmitting area A. The two outer second subsegments 1121 of the three second subsegments 1121 are positioned along portions of the edge of the first signal-transmitting area A on opposite sides of the length direction, while the center second subsegment 1121 is positioned along a portion of the edge of the first signal-transmitting area A on one end of the width direction. The first segment 111 is positioned on the glass plate 30 at a location corresponding to the sensor 20 and away from the first and second light-transmitting areas C and D to avoid physical obstruction of the rain sensor and ETC signals. Specifically, the distance between the heating filament 11 and the rain sensor is greater than or equal to 30 mm. The third segment 113 is positioned on the glass plate 30 at a location corresponding to the sensor 20.

[0088] It will be appreciated that by energizing the heating filament 11 through the two heating electrodes 12, the heating filament 11 generates heat, heating the location on the glass plate 30 corresponding to the location of the heating filament 11, thereby removing water, fog, frost, etc. on the glass plate 30 corresponding to the location of the heating filament 11. Because the heating filament 11 is arranged away from the first signal transmission area A, when the first sensor 21 acquires image information, the heating filament 11 can avoid physically blocking light from entering the first sensor 21, thereby facilitating the first sensor 21 to obtain complete image information. At the same time, the heating filament 11 can be prevented from reflecting light, thereby preventing the accuracy of the image information obtained by the first sensor 21.

[0089] In addition, the second section 112 of the heating wire 11 is distributed around the edge of the first signal transmission area A. When the second section 112 generates heat, the heat can be quickly transferred to the inside of the first signal transmission area A through the glass plate 30. Therefore, the heating wire 11 can dewater, defog or defrost the inside of the first signal transmission area A.

[0090] Referring to Figure 3 , this application provides a second embodiment of a heating element 10 for a vehicle window assembly 100. In this embodiment, the heating element 10 includes a heating wire 11 and a heating electrode 12. This embodiment differs from the first embodiment in that the structure of the second segment 112 of the heating wire 11 is different, and the relative positional relationship between the heating wire 11 and the first and second signal-transmitting areas A and B is different.

[0091] In this embodiment, the second segment 112 is linear. The two heating segment groups 111a of the first segment 111 are positioned opposite each other along the length of the glass sheet 30, and the two heating segment groups 111a are electrically connected via the second segment 112. Along the length of the glass sheet 30, two third segments 113 are positioned between the two heating segment groups 111a, spaced apart. The two heating segment groups 111a are connected to the two heating electrodes 12 via the two third segments 113.

[0092] In this embodiment, the heating filament 11 is located outside the first signal transmission area A, and at least partially within the second signal transmission area B. A portion of the first segment 111 of the heating filament 11 is located within the second signal transmission area B, while another portion is located outside the second signal transmission area B. Along the width of the glass sheet 30, each heating segment group 111a has a width L2, where L2 is greater than L0. The connecting segments 1112 of the two heating segment groups 111a are respectively positioned along the longitudinal edges of the first signal transmission area A on opposite sides. Specifically, in this embodiment, the connecting segments 1112 of the two heating segment groups 111a overlap with the longitudinal edges of the first signal transmission area A on opposite sides (with a certain dimensional tolerance). The second segment 112 is positioned along the width edge of the first signal transmission area A. The third segment 113 is located outside the first and second signal transmission areas A and B. Specifically, the third segment 113 is located on the inner surface 31 of the glass sheet 30 at a location corresponding to the sensor 20. In other embodiments, the connecting section 1112 of the two heating section groups 111a may also be spaced apart from a portion of the edge of the first signal transmission area A; the first section 111 of the heating wire 11 may also be completely located inside the second signal transmission area B.

[0093] In this embodiment, the spacing between two adjacent first sub-segments 1111 in each heating segment group 111a is 5 mm to 50 mm along the width of the glass sheet 30. The spacing between two adjacent first sub-segments 1111a in each first sub-segment group 1111 is 5 mm to 50 mm along the width of the glass sheet 30. This is because the distribution density of the first sub-segment groups 1111 in each heating segment group 111a and the distribution density of the first sub-segments 1111a in each first sub-segment group 1111 affect the heating effect of the first segments 111 on the first signal-transmitting areas A and B.

[0094] It will be appreciated that in this embodiment, since the heating wires 11 are arranged away from the first signal transmission area A, when the first sensor 21 acquires image information, the heating wires 11 are prevented from physically blocking light from entering the first sensor 21, thereby facilitating the first sensor 21 to obtain complete image information. This also prevents reflections from the heating wires 11, thereby preventing the accuracy of the image information acquired by the first sensor 21. Furthermore, the heating wires 11 are arranged in the second signal transmission area B, thereby enhancing the heating effect of the heating wires 11 on the glass plate 30. The heating wires 11 can also remove moisture, fog, or frost from the second signal transmission area B, thereby improving the accuracy of the image information acquired by the second sensor 22.

[0095] In addition, the connecting sections 1112 of the two heating section groups 111a are respectively arranged along the edges of the first signal transmission area A on opposite sides in the length direction. The heat of the connecting sections 1112 can be transferred from the opposite sides in the length direction of the first signal transmission area A to the interior of the first signal transmission area A through the glass plate 30; the second section 112 is arranged along the edge of one end of the first signal transmission area A in the width direction. The heat of the second section 112 can also be transferred from one end of the first signal transmission area A in the width direction to the interior of the first signal transmission area A through the glass plate 30.

[0096] Referring to Figure 6 , this application provides a third embodiment of a heating element 10 for a vehicle window assembly 100. In this embodiment, the heating element 10 includes a heating wire 11 and a heating electrode 12. This embodiment differs from the second embodiment in that the structure of the third segment 113 of the heating wire 11 is different, and the relative positional relationship between the heating wire 11 and the first signal-transmitting area A and the second signal-transmitting area B is different.

[0097] In this embodiment, the third segment 113 includes a straight segment 1131 and a curved segment 1132. The straight segment 1131 is straight, while the curved segment 1132 is roughly C-shaped. The straight segment 1131 and the curved segment 1132 are electrically connected to each other. Both the straight segment 1131 and the curved segment 1132 have free ends. There are two third segments 113. In other embodiments, the curved segment 1132 may have other shapes, such as a Z-shape.

[0098] In this embodiment, the second segment 112 is linear, and the two heating segment groups 111a are electrically connected to both ends of the second segment 112. The two third segments 113 are disposed opposite each other along the length of the glass sheet 30, and are electrically connected to the two heating segment groups 111a. Specifically, the free ends of the straight segments 1131 of the two third segments 113 are electrically connected to the second free ends of the two heating segment groups 111a, respectively, and the free ends of the curved segments 1132 of the two third segments 113 are electrically connected to the two heating electrodes 12.

[0099] In this embodiment, along the width of the glass sheet 30, the spacing between two adjacent first sub-segment groups 1111 in each heating segment group 111a is 5 mm to 50 mm. Along the width of the glass sheet 30, the spacing between two adjacent first sub-segments 1111a in each first sub-segment group 1111 is 5 mm to 50 mm. This is because the distribution density of the first sub-segment groups 1111 in each heating segment group 111a and the distribution density of the first sub-segments 1111a in each first sub-segment group 1111 affect the heating effect of the first segment 111 on the first signal-transmitting area A and the first signal-transmitting area B. In this embodiment, along the width of the glass sheet 30, the width of the connecting segment 1112, the width of the transition segment 1111b, and the width of the straight segment 1131 of the third segment 113 are all equal and are L0 / 4 (a certain dimensional tolerance is allowed).

[0100] In this embodiment, the heating filament 11 is located outside the first signal-transmitting area A, and at least partially within the second signal-transmitting area B. A portion of the first segment 111 of the heating filament 11 is located within the second signal-transmitting area B, while another portion is located outside the second signal-transmitting area B. Along the width of the glass sheet 30, the first signal-transmitting area A is located between the straight segment 1131 and the second segment 112 of the third segment 113. The second segment 112 is located along one widthwise edge of the first signal-transmitting area A, while the straight segment 1131 is located along the other widthwise edge of the first signal-transmitting area A. The connecting segments 1112 of the two heating segment groups 111a are located along opposite longitudinal edges of the first signal-transmitting area A. Specifically, in this embodiment, the straight segment 1131 overlaps with one widthwise edge of the first signal-transmitting area A (within a certain dimensional tolerance). The connecting segments 1112 of the two heating segment groups 111a overlap with opposite longitudinal edges of the first signal-transmitting area A (within a certain dimensional tolerance). The bent section 1132 of the third segment 113 is located outside the first signal-transmitting area A and the second signal-transmitting area B. Specifically, the bent section 1132 of the third segment 113 is located on the inner surface 31 of the glass plate 30 at a position corresponding to the sensor 20. In other embodiments, the straight segment 1131 may be spaced apart from a portion of the edge of the first signal-transmitting area A at the other end in the width direction; the connecting section 1112 of the two heating segment groups 111a may be spaced apart from a portion of the edge of the first signal-transmitting area A; and the first segment 111 of the heating wire 11 may be located entirely within the second signal-transmitting area B.

[0101] It will be appreciated that in this embodiment, since the heating filament 11 is arranged away from the first signal transmission area A, when the first sensor 21 acquires image information, the heating filament 11 is prevented from physically blocking light from entering the first sensor 21, thereby facilitating the first sensor 21 to obtain complete image information. This also prevents reflections from the heating filament 11, thereby preventing the accuracy of the image information acquired by the first sensor 21. Furthermore, the heating filament 11 is arranged in the second signal transmission area B, thereby enhancing the heating effect of the heating filament 11 on the glass sheet 30. The heating filament 11 can remove moisture, fog, or frost from the second signal transmission area B, thereby improving the accuracy of the image information acquired by the second sensor 22. The third segment 113 is provided with a bent section 1132, which improves the heating efficiency of the heating element 10 at the location on the glass sheet 30 corresponding to the sensor 20.

[0102] In addition, the second section 112 is arranged along the edge of the first signal transmission area A at one end in the width direction, the straight line section 1131 is arranged along the partial edge of the first signal transmission area A at the other end in the width direction, and the connecting section 1112 of the two heating section groups 111a is arranged along the partial edges of the first signal transmission area A on opposite sides in the length direction. This can ensure that heat is transferred to the first signal transmission area A through the glass plate 30 at both opposite ends in the width direction and on both opposite sides in the length direction of the first signal transmission area A, while ensuring that the first signal transmission area A is not physically blocked, and at the same time, ensuring the heating uniformity and heating rate of the first signal transmission area A.

[0103] Referring to FIG. 7 , this application provides a fourth embodiment of a heating element 10 for a vehicle window assembly 100. In this embodiment, the heating element 10 includes a heating wire 11 and a heating electrode 12. This embodiment differs from the third embodiment in that the structure of the second segment 112 of the heating wire 11 is different.

[0104] In this embodiment, the second segment 112 has a zigzag shape. The second segment 112 includes a plurality of third sub-segments 1123 and a plurality of connecting segments 1124. Two adjacent third sub-segments 1123 are connected by a connecting segment 1124. Each third sub-segment 1123 extends along the length of the glass sheet 30, and each connecting segment 1124 extends along the width of the glass sheet 30. The connecting segments 1124 are spaced apart along the length of the glass sheet 30, and each third sub-segment 1123 is used to electrically connect the adjacent ends of two adjacent connecting segments 1124.

[0105] In this embodiment, the dimension w2 of each third sub-segment 1123 along the length of the glass sheet 30 is greater than or equal to 5 mm. In other embodiments, the heating filament 11 is an enameled wire. To meet the manipulator's process requirements for arranging multiple third sub-segments 1123, w2 is greater than or equal to 12 mm. Because some third sub-segments 1123 in the second segment 112 are located away from the bottom of the first signal transmission area A, a too small w2 would affect the heating effect of the second segment 112 on the first signal transmission area A. This ensures that the second segment 112 maintains a sufficient heating effect on the first signal transmission area A. Preferably, w2 is greater than or equal to 5 mm and is less than the spacing along the width of the glass sheet 30 between two adjacent first sub-segment groups 1111 in each heating segment group 111a.

[0106] In this embodiment, the width w1 of each connecting segment 1124 along the width of the glass sheet 30 is less than or equal to 20 mm. Because the width w1 of the connecting segment 1124 affects the heating effect of the second segment 112 on the first signal-transmitting area A, w1 is set to be less than or equal to 20 mm. This ensures that the second segment 112 maintains a sufficient heating effect on the first signal-transmitting area A.

[0107] In this embodiment, the heating filament 11 is located outside the first signal-transmitting area A, and at least partially within the second signal-transmitting area B. A portion of the first segment 111 of the heating filament 11 is located within the second signal-transmitting area B, while another portion is located outside the second signal-transmitting area B. Along the width of the glass sheet 30, the first signal-transmitting area A is located between the straight segment 1131 and the second segment 112 of the third segment 113. The second segment 112 is located along one widthwise edge of the first signal-transmitting area A, while the straight segment 1131 is located along the other widthwise edge of the first signal-transmitting area A. The connecting segments 1112 of the two heating segment groups 111a are located along opposite longitudinal edges of the first signal-transmitting area A. Specifically, in this embodiment, the straight segment 1131 overlaps with one widthwise edge of the first signal-transmitting area A (within a certain dimensional tolerance). The connecting segments 1112 of the two heating segment groups 111a overlap with opposite longitudinal edges of the first signal-transmitting area A (within a certain dimensional tolerance). The bent section 1132 of the third segment 113 is located outside the first signal-transmitting area A and the second signal-transmitting area B. Specifically, the bent section 1132 of the third segment 113 is located on the inner surface 31 of the glass plate 30 at a position corresponding to the sensor 20. In other embodiments, the straight segment 1131 may be spaced apart from a portion of the edge of the first signal-transmitting area A at one end in the width direction; the connecting section 1112 of the two heating segment groups 111a may be spaced apart from a portion of the edge of the first signal-transmitting area A; and the first segment 111 of the heating wire 11 may be located entirely within the second signal-transmitting area B.

[0108] In this embodiment, along the width of the glass sheet 30, the spacing between two adjacent first sub-segment groups 1111 in each heating segment group 111a is 5 mm to 50 mm. Along the width of the glass sheet 30, the spacing between two adjacent first sub-segments 1111a in each first sub-segment group 1111 is 5 mm to 50 mm. This is because the distribution density of the first sub-segment groups 1111 in each heating segment group 111a and the distribution density of the first sub-segments 1111a in each first sub-segment group 1111 affect the heating effect of the first segment 111 on the first signal-transmitting area A and the first signal-transmitting area B. In this embodiment, along the width of the glass sheet 30, the width of the connecting segment 1112, the width of the transition segment 1111b, and the width of the straight segment 1131 of the third segment 113 are all equal and are L0 / 4 (a certain dimensional tolerance is allowed).

[0109] It will be appreciated that in this embodiment, since the heating filament 11 is arranged away from the first signal transmission area A, when the first sensor 21 acquires image information, the heating filament 11 is prevented from physically blocking light from entering the first sensor 21, thereby facilitating the first sensor 21 to obtain complete image information. This also prevents reflections from the heating filament 11, thereby preventing the accuracy of the image information acquired by the first sensor 21. Furthermore, the heating filament 11 is arranged in the second signal transmission area B, thereby enhancing the heating effect of the heating filament 11 on the glass sheet 30. The heating filament 11 can remove moisture, fog, or frost from the second signal transmission area B, thereby improving the accuracy of the image information acquired by the second sensor 22. The third segment 113 is provided with a bent section 1132, which improves the heating efficiency of the heating element 10 at the location on the glass sheet 30 corresponding to the sensor 20.

[0110] Furthermore, the second segment 112 is positioned along the edge of the first signal-transmitting area A at one end in the width direction, the straight segment 1131 is positioned along a portion of the edge of the first signal-transmitting area A at the other end in the width direction, and the connecting segment 1112 of the two heating segment groups 111a is positioned along portions of the edge of the first signal-transmitting area A at opposite ends in the length direction. This ensures that heat is transferred from both opposite ends in the width direction and opposite sides in the length direction of the first signal-transmitting area A through the glass sheet 30 to the first signal-transmitting area A. This ensures that the first signal-transmitting area A is not physically obstructed while maintaining a heating effect in the first signal-transmitting area A. The zigzag shape of the second segment 112 increases its length, thereby improving the heating efficiency of the first signal-transmitting area A and the second signal-transmitting area B.

[0111] In one possible implementation, the heating wire 11 is disposed around at least three peripheries of the first signal transmission area A. Specifically, the heating wire 11 in the first, second, third, and fourth embodiments of the present application is disposed around three peripheries of the first signal transmission area A.

[0112] In one possible embodiment, as shown in FIG2 , to enhance the aesthetics of the vehicle window assembly 100, a black border region 40 is provided around the perimeter of the glass panel 30. Black border region 40 can be used to shield and protect components within the vehicle. On the one hand, black border region 40 shields components within the vehicle, ensuring an overall aesthetic appearance when viewed from the outside. On the other hand, black border region 40 also provides UV protection, preventing components within vehicle 1000 from aging and damage due to direct sunlight, thereby extending the service life of the components within vehicle 1000.

[0113] In a possible implementation manner, the number of the first sensor 21 is at least one, and the number of the second sensor 22 is at least one.

[0114] In one possible embodiment, as shown in FIG8 , there are two first sensors 21, each spaced apart from the second sensor 22. In this embodiment, the glass plate 30 includes two first signal-transmitting areas A and one second signal-transmitting area B. Both first signal-transmitting areas A are at least partially located within the second signal-transmitting area B. At least one heating wire 11 avoids the two first signal-transmitting areas A and is at least partially located within the second signal-transmitting area B.

[0115] In a possible implementation manner, the at least one heating wire 11 is disposed around at least a portion of the periphery of the two first signal transmission areas A.

[0116] In a possible implementation, the first sensor 21 and / or the second sensor 22 is / are selected from at least one of a visible light camera, an infrared camera, and a laser radar.

[0117] The present application also provides a vehicle 1000, please refer to Figure 9, the vehicle 1000 includes a vehicle body 200 and the window assembly 100 as described above, the window assembly 100 is mounted on the vehicle body 200. Specifically, the window assembly 100 is described above and will not be repeated here.
