[0028] Please see Figure 1 , Figure 1This is a structural schematic diagram of a vehicle 100 provided in an embodiment of the present invention. The vehicle 100 includes a body 10, a glass assembly 20, a windshield wiper 30, and a camera 40. The glass assembly 20 is mounted on the body 10, and the windshield wiper 30 and camera 40 are mounted on the glass assembly 20. Therefore, by integrating the windshield wiper 30 and camera 40 onto the glass assembly 20, on the one hand, the functional integration of the glass assembly 20 is improved, and the space utilization of the glass assembly 20 is also improved; on the other hand, it facilitates various wireless devices within the vehicle 100 to capture radio signals in the air and transmit the signals generated by the wireless devices, thus realizing multiple onboard functions of the vehicle 100.

[0029] For example, in this embodiment, the glass assembly 20 is a window 101 provided on the vehicle body 10.

[0031] It should be noted that, Figure 1 The purpose is merely to illustrate the arrangement between the vehicle body 10 and the glass assembly 20, and not to make specific limitations on the connection positions, connection relationships and specific structures of the various components. Figure 1 The description of the vehicle 100 in this embodiment is merely illustrative and does not constitute a specific limitation on the vehicle 100. In other embodiments of this utility model, the vehicle 100 may include... Figure 1 The vehicle 100 may also include, but is not limited to, wheels, seats, or power units, etc., as shown in the diagram.

[0032] Please refer to the following: Figure 1 and Figure 2 , Figure 2This is a first-view structural schematic diagram of the glass assembly 20 provided in this embodiment of the present invention. The glass assembly 20 includes a glass body 3, a heating wire 4, and an antenna 5. The heating wire 4 is disposed on the glass body 3. The antenna 5 is disposed on the glass body 3. The antenna 5 and the heating wire 4 are arranged alternately in the plane containing the glass body 3. The antenna 5 and the heating wire 4 are independently disposed.

[0033] The glass assembly 20 provided in this embodiment of the present invention is based on the arrangement of an antenna 5 and a heating wire 4 on a glass body 3. The antenna 5 and the heating wire 4 are arranged in an alternating pattern on the orthographic projection of the glass body 3, and the antenna 5 and the heating wire 4 are arranged independently of each other. On the one hand, the alternating arrangement of the heating wire 4 and the antenna 5 utilizes the blank area between the heating wires 4 to arrange the antenna 5, thereby improving the space utilization of the glass body 3, increasing the functional integration and functional density of the glass assembly 20, and simplifying the structure of the antenna 5 glass assembly. On the other hand, the alternating arrangement of the heating wire 4 and the antenna 5 increases the clearance between them in a two-dimensional plane, thereby reducing the electromagnetic radiation noise generated by the heating wire 4 to the antenna 5 when it is powered on, improving the electromagnetic compatibility between the heating wire 4 and the antenna 5, and improving the reliability and sensitivity of the signal transmitted by the antenna 5.

[0034] Please refer to the following: Figures 2 to 4 , Figure 3 yes Figure 1 A second-view structural schematic diagram of the glass assembly 20 of the vehicle; Figure 4 yes Figure 2 This is an enlarged view of part I of the glass assembly 20 of the vehicle. The heating wire 4 includes a first heating wire 41, a second heating wire 42, multiple third heating wires 43, and two heating busbars 44. The first heating wire 41, the second heating wire 42, and the multiple third heating wires 43 extend between the two heating busbars 44. The first heating wire 41 is located at the bottom of the glass body 3. The second heating wire 42 is located at the top of the glass body 3. The two heating busbars 44 connect to the first heating wire 41 and the second heating wire 42 to form a first heating area 401. The second heating wire 42 includes a first heating segment 425 and a second heating segment 426, which connect to form a second heating area 402. The multiple third heating wires 43 are spaced apart within the second heating area 402 along a first direction F1. The antenna 5 includes a first radiator 51 and a second radiator 52. The first radiator 51 and the second radiator 52 are spaced apart within the second heating area 402. The first radiator 51 and the second radiator 52 are each configured in a grid structure. Therefore, by spaced the first radiator 51 and the second radiator 52 within the second heating zone 402, the radiating structure of the antenna 5 is prevented from intersecting with the heating wire 4, thus improving the integrity of the antenna 5's signal transmission and reducing transmission loss.

[0035] Please refer to the following: Figure 2 and Figure 5 , Figure 5 yes Figure 2 The diagram shows the structure of the glass body 3, heating wire 4, and antenna 5 of the glass assembly 20 of the vehicle 100. Exemplarily, in this embodiment, the antenna 5 further includes a first feed point 53 and a second feed point 54. The first feed point 53 is connected between the first radiator 51 and the connector. The second feed point 54 is connected between the second radiator 52 and the connector. The connector is used for connection to an amplifier or power supply.

[0036] Antenna 5 also includes a first coupling stub 55 and a second coupling stub 56. The first coupling stub 55 is selectively coupled to the first radiator 51. The second coupling stub 56 is selectively coupled to the second radiator 52. The first coupling stub 55 and the second coupling stub 56 are spaced apart along the second direction F2 within the first heating zone 401 and are arranged alternately with multiple third heating wires 43. Thus, on the one hand, by setting the first coupling stub 55 and the first radiator 51 and the second coupling stub 56 and the second radiator 52 at different positions, and by setting the first coupling stub 55 selectively coupled to the first radiator 51 and the second coupling stub 56 selectively coupled to the second radiator 52, antenna 5 can adapt to the reception of signals in different frequency bands to cover a variety of radio services.

[0037] Please refer to the following: Figure 5 and Figure 6 , Figure 6 yes Figure 2 An enlarged view of part II of the glass assembly 20 of the vehicle. Exemplarily, in this embodiment, the first radiator 51 and the second radiator 52 each include multiple first conductive lines 521, multiple second conductive lines 522, and two third conductive lines 523. The multiple first conductive lines 521 are arranged at intervals along a first direction F1 and connected to the multiple second conductive lines 522 and the two third conductive lines 523. The multiple second conductive lines 522 are arranged at intervals along a second direction F2 and are staggered with the multiple first conductive lines 521. The two third conductive lines 523 are located at opposite ends of each first conductive line 521 in the second direction F2. Thus, the multiple first conductive lines 511, multiple first conductive lines 521, and multiple second conductive lines 522 can switch to select the best signal path to combat signal fading, thereby optimizing and dividing the functions of the antenna 5 and improving the overall reception diversity, stability, and bandwidth of the antenna 5. The first radiator 51 and the second radiator 52 each include a plurality of spaced conductor segments 510, thereby enabling the antenna 5 to receive multi-band signals to cover a variety of radio services. For example, at least one of the first conductive line 521, the second conductive line 522, and the third conductive line 523 may also include a plurality of spaced conductor segments 510.

[0038] Please refer to it again. Figure 2 , Figure 3 and Figure 6 The number of first coupling branches 55 and the number of second coupling branches 56 can be set to one or more. In some embodiments, at least one first coupling branch 55 includes a plurality of first branch segments 551 spaced apart along a first direction F1, and at least one second coupling branch 56 includes a plurality of second branch segments 561 spaced apart along the first direction F1. Exemplarily, in this embodiment, the number of first coupling branches 55 and the number of second coupling branches 56 are each set to two. The first coupling branch 55 located on the outermost side of the two first coupling branches 55 in the second direction F2 is provided with a plurality of first branch segments 551, and the two second coupling branches 56 include a plurality of second branch segments 561 spaced apart along the first direction F1.

[0039] It should be noted that the number of first coupling stubs 55, the number of second coupling stubs 56, the number of first stub segments 551, and the number of second stub segments 561 can be set according to the application scenario of antenna 5, and this application embodiment does not make specific limitations.

[0040] In some embodiments, the antenna 5 further includes a third coupling stub 57. The third coupling stub 57 is disposed within the first heating region 401 and is spaced apart between the first coupling stub 55 and the second coupling stub 56. The third coupling stub 57 is disposed independently of the first radiator 51 and the second radiator 52.

[0041] The glass body 3 is roughly rectangular in shape. For accuracy, all references to direction in this text should be expressed in terms of orientation. Figure 2 For reference, the term "first direction F1" as used in the embodiments and claims herein refers to the direction parallel to the short side of the glass body 3, i.e., the up-down direction. The term "second direction F2" refers to the direction parallel to the long side of the glass body 3, i.e., the left-right direction. The first direction F1 and the second direction F2 constitute two orthogonal directions within the plane containing the glass body 3. For ease of description, the up-down and left-right orientations in this utility model are relative positions and do not constitute a limitation on implementation. The first direction F1 and the second direction F2 can be customized according to the specific structure of the product and the viewing angle presented in the accompanying drawings; this utility model does not impose specific limitations.

[0042] For example, in this embodiment, the two sides of the first heating wire 41 in the second direction F2, the two sides of the second heating wire 42 in the second direction F2, and the two sides of the multiple third heating wires 43 in the second direction F2 are all connected between the two heating busbars 44. The second direction F2 intersects the first direction F1. Thus, on the one hand, the arrangement of the first heating wire 41, the second heating wire 42, the multiple third heating wires 43, and the two heating busbars 44 realizes a non-linear arrangement between the bus and the branches and an uninterrupted power supply mode. The two heating busbars 44 supply power to the first heating wire 41, the second heating wire 42, and the multiple third heating wires 43 with lower resistance, which improves the overall potential uniformity of the heating wires 4 and enhances the heating efficiency and reliability of the heating wires 4. For example, in this embodiment, the second direction F2 is perpendicular to the first direction F1. Of course, in some embodiments, the second direction F2 and the first direction F1 may also be arranged at a non-right angle, and this embodiment of the present invention does not impose specific limitations.

[0043] Please refer to it again. Figure 2 and Figure 3 In this embodiment, for example, the glass body 3 includes a light-transmitting area 301 and a colored area 302. The colored area 302 surrounds the periphery of the light-transmitting area 301. A first heating wire 41 is disposed on the bottom edge of the glass body 3 near the colored area 302. A second heating wire 42 is disposed on the top edge of the glass body 3 near the colored area 302. Thus, by distributing the first heating wire 41 and the second heating wire 42 on the bottom and top edges of the glass body 3 near the colored area 302, respectively, the first heating wire 41 and the second heating wire 42 can directly and quickly raise the temperature of the edge of the glass body 3, preventing frost formation on the edge of the glass body 3, improving the heating uniformity of the entire surface of the glass body 3, improving the defrosting effect at the edge and center of the glass body 3, and enhancing the driving experience and driving safety.

[0044] The glass body 3 can be, but is not limited to, tempered glass, laminated glass, etc. The distance between the heating wire 4 and the antenna 5 is greater than or equal to 2mm, thereby avoiding the problem that the electromagnetic field generated by the heating wire 4 when energized will degrade the signal reception quality of the antenna 5, improving the signal transmission performance of the antenna connector and reducing signal interference.

[0045] Please refer to it again. Figure 2 , Figure 3 and Figure 5In some embodiments, a marking structure 412 is provided at the bottom of the heating wire 4. The marking structure 412 is used to mark the start and end positions of the wiper arm. Thus, the glass assembly 20 uses a portion of the structure of the heating wire 4 as the marking structure 412, which can be clearly observed by the user. This eliminates the need for additional positioning tools or marking structures to mark the start and end positions of the wiper arm 31, improving the ease and reliability of wiper arm 31 installation, enhancing the aesthetics of the glass assembly 20, and giving the marking structure 412 a heating defrosting function, thereby reducing manufacturing costs.

[0046] For example, in this embodiment, the first heating wire 41 is provided with an identification structure 412. The identification structure 412 and the first heating wire 41 are an integral structure, that is, the identification structure 412 is a part of the structure of the first heating wire 41 disposed on the glass surface and serves as a visual identification line. Of course, in some embodiments, the identification structure 412 can be disposed independently of the first heating wire 41 and fixedly connected.

[0047] The wiper 30 includes a wiper arm 31 and a wiper cover 32. A mounting hole 303 is provided at the bottom of the glass body 3. The wiper cover 32 is fitted onto the connecting end of the wiper arm 31 and installed in the mounting hole 303. The wiper arm 31 includes a first arm 311 and a second arm 312. One end of the first arm 311 is rotatably mounted in the mounting hole 303 via a rotating shaft, and the other end of the first arm 311 is fixedly connected to the second arm 312. The swing axis of the first arm 311 intersects the swing axis of the second arm 312. When the wiper arm 31 swings to its start and stop positions, the swing axis of the second arm 312 coincides with the extension trajectory of the marking structure 412. Therefore, on the one hand, users can quickly install the wiper 30 based on the marking structure 412, improving the convenience and reliability of installing the wiper arm 31, enhancing the aesthetics of the glass assembly 20, and giving the marking structure 412 a heating and defrosting function, thus reducing manufacturing costs. On the other hand, by bending the first arm 311 and the second arm 312, the swing range of the wiper arm 31 is increased. For example, in this embodiment, the wiper arm 31 is approximately L-shaped. Of course, in some embodiments, the first arm 311 can be omitted, and the wiper cover 32 can also be omitted.

[0048] For example, in this embodiment, the swing area of ​​the wiper arm 31 is defined as the wiper area S. The wiper area S includes a first boundary B1, a second boundary B2, a third boundary B3, and a fourth boundary B4. The first boundary B1, the second boundary B2, the third boundary B3, and the fourth boundary B4 are connected to form the wiper area S. The first boundary B1 and the second boundary B2 are configured as straight edges. The third boundary B3 and the fourth boundary B4 are configured as curved edges. The third boundary B3 is the swing trajectory of the outer edge of the first arm 311, and the fourth boundary B4 is the swing trajectory of the outer edge of the second arm 312. The marking structure 412 at least partially overlaps with the first boundary B1.

[0049] The start and end positions of the wiper arm 31 refer to the initial installation position of the wiper arm 31, that is, the position corresponding to the first boundary B1. The area covered by the heating wire 4 at least partially overlaps with the wiper area S, thereby ensuring the normal start-up of the wiper 30 and enabling the heating wire 4 to perform rapid defrosting on the wiper area S. In some embodiments, the area covered by the heating wire 4 covers the wiper area S.

[0050] For example, in this embodiment, a wiper sleeve 32 is installed at the bottom of the glass body 3. Therefore, the wiper sleeve 32 reduces friction between the wiper arm 31 and the glass frame 6. The wiper sleeve 32 also provides insulation between the wiper arm 31 and the heating wire 4, creating a safe distance between the heating wire 4 and the wiper sleeve 32 of the wiper 30, thus achieving electrical isolation and preventing any possible short circuit or leakage risks.

[0051] like Figure 2 and Figure 3As shown, the materials of the wiper cover 32 include, but are not limited to, rubber materials, chlorinated and / or sulfur-containing elastic materials, etc. Understandably, during long-term use, sulfides or other chemical additives in the material of the wiper cover 32 will be slowly released, and the heating wire 4 (usually silver paste or a similar metallic material) will accelerate this chemical process when heated by electricity. Under the combined action of heat and moisture, the released chemical substances will undergo a sulfidation reaction with the metal of the heating wire 4, generating non-conductive metal sulfides (such as black silver sulfide). In this embodiment of the invention, a first gap D1 is formed between the wiper cover 32 and the first clearance structure 411. The first gap D1 is greater than or equal to 5 mm. Understandably, when the gap between the wiper cover 32 and the first clearance structure 411 is too small, the wiper cover 32 will come into physical contact with the heating wire 4, causing a sulfidation reaction and leading to the failure of the first clearance structure 411, as well as interfering with the swinging motion of the wiper arm 31. When the gap between the wiper cover 32 and the heating wire 4 is too large, the defrosting effect of the first clearance structure 411 on the glass body 3 is reduced. Therefore, this utility model, based on setting the first gap D1 within a suitable range, prevents the wiper cover 32 from coming into physical contact with the first clearance structure 411 and causing a sulfidation reaction, extends the safety and service life of the glass assembly 20, and ensures that the first clearance structure 411 has a good defrosting effect on the glass body 3.

[0052] In some embodiments, the first gap D1 is greater than or equal to 10 mm. The first gap D1 can be, but is not limited to, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm.

[0053] Mounting hole 303 is used for mounting wiper arm 31. The first heating wire 41 is provided with a first clearance structure 411 that avoids the mounting hole 303. Among the multiple third heating wires 43, the third heating wire 43 that is arranged adjacent to the first heating wire 41 is defined as the irregular heating wire 430. The irregular heating wire 430 is connected in parallel with the first clearance structure 411. Therefore, on the one hand, by setting the first heating wire 41 to avoid the mounting hole 303, the problem of the mounting structure of the wiper arm 31 damaging the first heating wire 41 is avoided, and the sulfidation reaction caused by the close proximity between the heating wire 4 and the wiper protective sleeve 32 is avoided, thus extending the service life of the heating wire 4; on the other hand, by setting the glass body 3 to avoid local overheating, and by setting the third heating wire 43 adjacent to the first heating wire 41 to be connected in parallel with the first avoidance structure 411, the defrosting effect of the heating wire 4 in the area near the wiper arm 31 is improved, and the problem of abnormal hot spots or power loss points in the area near the wiper arm 31 caused by the close proximity between the first heating wire 41 and the first avoidance structure 411 is avoided.

[0054] Exemplarily, in this embodiment, the first clearance structure 411 is configured as a curved structure formed by the first heating wire 41 protruding outward toward the side opposite to the second heating wire 42. Thus, the first clearance structure 411 provides sufficient installation space for the wiper arm 31, avoids interference between the heating wire 4 and the wiper arm 31, and reduces the risk of sulfidation reaction between the heating wire 4 and the wiper cover 32. Furthermore, the curvature of the first clearance structure 411 maintains the first heating wire 41 as a continuous and complete conductor, allowing current to flow unimpeded through the curved first clearance structure 411, resulting in uniform resistance throughout the heating circuit. Exemplarily, in this embodiment, the first clearance structure 411 can be a U-shaped structure. Of course, in some embodiments, the first clearance structure 411 can also be a C-shaped structure, etc., and this embodiment of the present invention does not impose specific limitations.

[0055] The irregularly shaped heating wire 430 includes two heating structures 431. The two heating structures 431 are located on both sides of the mounting hole 303 in the second direction F2. As a result, the current shunted from the first heating wire 41 can be evenly distributed to the two heating structures 431, thereby avoiding the current overload or resistance mismatch problems that would occur if the two heating structures 431 were asymmetrically arranged relative to the mounting hole 303, and achieving uniform heating of the heating wire 4 around the mounting hole 303.

[0056] Each heating structure 431 extends towards the first clearance structure 411 from one end near the mounting hole 303 in the second direction F2. Therefore, by extending the heating structure 431 towards the first clearance structure 411 from the end near the mounting hole 303, the current path is shortened, resistance is reduced, energy loss is decreased, and the heating effect of the heating structure 431 is improved.

[0057] For example, in this embodiment, the heating structure 431 is generally L-shaped. Specifically, the heating structure 431 includes a first heating part 4311 and a second heating part 4312. In other words, the extending direction of the first heating part 4311 is perpendicular to the extending direction of the second heating part 4312. This ensures that the first heating part 4311 is arranged parallel to the adjacent third heating wire 43 and the first heating wire 41, thereby achieving uniform resistance throughout the heating circuit, preventing abnormal hot spots or power loss points, and enabling the second heating part 4312 to be connected in parallel with the first heating wire 41.

[0058] The first heating element 4311 and the second heating element 4312 are smoothly connected. Specifically, the first heating element 4311 and the second heating element 4312 are connected at an arc angle, thereby providing a margin for thermal expansion and deformation of the heating structure 431 and avoiding the problem of breakage of the heating structure 431. Of course, in some embodiments, the first heating element 4311 and the second heating element 4312 may also be connected at a sharp angle.

[0059] The length of the first clearance structure 411 in the second direction F2 is greater than the length of the two second heating parts 4312 in the second direction F2. As a result, the first heating wire 41 will not be too far from the wiper cover 32, so that the first heating wire 41 can increase the defrosting coverage area in the vicinity of the wiper cover 32 and avoid the problem of the wiper arm being unable to rotate or having difficulty rotating.

[0060] In some embodiments, the vehicle 100 further includes a camera 40 and an antenna connector. The camera 40 is provided with a lens aperture 4001. The camera 40 and the antenna connector are mounted on the side wall of the glass body 3 facing the interior of the vehicle 100 and are disposed to avoid interference with the heating wire 4, thereby preventing the heating wire 4 from interfering with the operating parameters of the camera 40 and the antenna connector.

[0061] like Figure 2 and Figure 4As shown, exemplarily, in this embodiment, a camera area 304 is provided on the top of the glass body 3. The second heating wire 42 is provided with a second avoidance structure 421 that avoids the camera area 304; and / or, an antenna connector area 305 is provided on the top of the glass body 3, and the second heating wire 42 is provided with a third avoidance structure 422 that avoids the antenna connector area 305. Thus, on the one hand, by providing the second heating wire 42 with a second avoidance structure 421 that avoids the camera area 304, the second avoidance structure 421 can prevent the second heating wire 42 from interfering with the shooting operation of the camera 40, and reduce the risk of damage to the camera 40 caused by the heat generated by the second heating wire 42 when it is powered on. It can also meet the defrosting requirements of the glass body 3 corresponding to the coverage area and edge area of ​​the camera 40, improve the accuracy and reliability of the image acquisition by the camera 40, and avoid the windshield wiper 30 of the vehicle 100 being stuck by frost when passing over the camera 40 and the area near the camera 40. On the one hand, the second heating wire 42 is provided with a third clearance structure 422 that avoids the antenna connector area 305. This avoids the problem of electromagnetic interference generated by the third clearance structure 422 when it is energized, which degrades the signal reception quality of the antenna 5. This improves the signal transmission performance of the antenna connector installed in the antenna connector area 305 and reduces signal interference. On the other hand, it avoids the problem of the second heating wire 42 interfering with the installation of the antenna connector and avoids physical contact between the antenna connector and the second heating wire 42. This prevents the current of the heating circuit of the heating wire 4 from leaking into the antenna 5 and causing a signal short circuit or circuit damage.

[0062] The camera area 304 is used for mounting the camera 40. It should be noted that the avoidance arrangement between the second avoidance structure 421 and the camera area 304 refers to the avoidance arrangement between the second heating wire 42 and the image acquisition viewing angle area of ​​the camera 40, and not to the avoidance arrangement between the second avoidance structure 421 and the mounting area of ​​the camera 40. Specifically, the camera 40 is provided with a lens hole 4001, and the second avoidance structure 421 avoids the lens hole 4001 of the camera 40.

[0063] For example, in this embodiment, the camera area 304 is located within the shading area 302. Thus, by placing the camera 40 in the shading area 302, on the one hand, light reflected from objects such as the dashboard inside the vehicle 100 is prevented from entering the camera 40, thereby improving the acquisition effect of the camera 40; on the other hand, the camera 40 is less conspicuous from outside the vehicle, maintaining the overall appearance and aesthetics of the vehicle 100.

[0064] For example, in this embodiment, the second heating section 426 is disposed between the first heating section 425 and the third heating line 43. The first heating section 425 and the second heating section 426 are each provided with a second clearance structure 421. The first heating section 425 is provided with a third clearance structure 422. Thus, the arrangement of the first heating section 425 and the second heating section 426 expands the heating range of the second heating line 42, allowing the second heating line 42 to uniformly cover the top area of ​​the glass body 3. This satisfies the defrosting requirements of the coverage area and edge area of ​​the glass body 3 corresponding to the camera 40, improves the accuracy and reliability of the images captured by the camera 40, avoids the problem of the windshield wiper 30 of the vehicle 100 being stuck with frost when passing over the camera 40 and the area near the camera 40, and enhances the driving experience and driving safety.

[0065] For example, in this embodiment, the curvature of the second clearance structure 421 provided on the first heating section 425 is the same as or approximately the same as the curvature of the second clearance structure 421 provided on the second heating section 426, thereby improving the heating uniformity of the imaging area 304. Of course, in some embodiments, the curvature of the second clearance structure 421 provided on the first heating section 425 may be different from the curvature of the second clearance structure 421 provided on the second heating section 426, and this embodiment of the present invention does not impose specific limitations.

[0066] For example, in this embodiment, a portion of the second heating wire 42 is disposed on the light-transmitting area 301 of the glass body 3, and the remaining portion of the second heating wire 42 is disposed on the colored area 302 of the glass body 3. It should be noted that the location of the first heating wire 41 can be set according to the actual situation, and this embodiment of the present invention does not impose a specific limitation.

[0067] The antenna connector area 305 is also located within the colored area 302. Therefore, by placing the antenna connector area 305 within the colored area 302, on the one hand, the antenna connector is less conspicuous from the outside of the vehicle, maintaining the overall integrity and aesthetics of the vehicle 100's appearance; on the other hand, the colored material has good thermal stability, allowing the portion of the glass body 3 corresponding to the colored area 302 to isolate the antenna connector from external temperature fluctuations, providing a stable physical environment for the antenna connector and reducing the risk of loosening at the connection point between the antenna connector and the glass body 3 due to thermal expansion and contraction. The colored material can be, but is not limited to, ceramic glaze.

[0068] For example, in this embodiment, the camera 40 and the antenna connector are staggered in the first direction F1 and arranged at intervals along the second direction F2. The second clearance structure 421 is configured as a curved structure formed by the second heating wire 42 being recessed inward toward the side facing the first heating wire 41. The third clearance structure 422 is configured as a curved structure formed by the second heating wire 42 being convex outward toward the side facing away from the first heating wire 41. Therefore, on the one hand, by staggering the camera 40 and the antenna connector in the first direction F1 and arranging them at intervals along the second direction F2, a physical and electromagnetic isolation zone is established between the camera 40 and the antenna connector, reducing the possibility of signal crosstalk, improving the purity of the imaging of the camera 40 and the signal transmitted by the antenna connector, and avoiding physical collisions in the narrow top area of ​​the glass body 3, which facilitates the assembly and maintenance of the imaging of the camera 40 and the antenna connector; on the other hand, by bending the second avoidance structure 421 and the third avoidance structure 422 in opposite directions, a perfect three-dimensional space fit is achieved between the heating wire 4 and the camera 40 and the antenna connector, improving the functional integration of the glass assembly 20, maintaining the continuity of the heating current loop of the heating wire 4, avoiding the need for additional jumpers or conductive silver paste connections due to the disconnection of the heating wire 4, and improving the heating uniformity and reliability of the glass body 3.

[0069] For example, in this embodiment, the second avoidance structure 421 and the third avoidance structure 422 can each be a U-shaped structure. Of course, in some embodiments, the second avoidance structure 421 and the third avoidance structure 422 can each be a C-shaped structure, etc., and this embodiment of the present invention does not make specific limitations.

[0070] For example, in this embodiment, multiple third heating wires 43 located between the second heating wire 42 and the irregularly shaped heating wire 430 are spaced apart and arranged parallel to each other along the first direction F1. Multiple third heating wires 43 located between the second heating wire 42 and the irregularly shaped heating wire 430 extend along the second direction F2. Therefore, by setting multiple third heating wires 43 spaced apart and arranged parallel to each other along the first direction F1, on the one hand, the aesthetics of the wiring of the heating wire 4 are improved; on the other hand, the uniformity of the overall heat distribution of the heating wire 4 is improved; furthermore, the extension of multiple third heating wires 43 along the second direction F2 increases the length of the inner heating wire 423, thereby reducing the total resistance of the inner heating wire 423, increasing the power, and thus improving the heating efficiency and heating effect of the heating wire 4. Adjacent third heating wires 43 are arranged at equal intervals.

[0071] A second gap D2 is formed between any two adjacent third heating wires 43 located between the second heating wire 42 and the irregular heating wire 430. The second gap D2 is 27.5mm-28.5mm. It can be understood that when the second gap D2 is too small, the heating power is too high, the circuit load is too large, which can easily damage the power supply circuit, posing a safety hazard, increasing production costs, and reducing production yield. When the second gap D2 is too large, the heating of the heating wires is uneven, reducing the frosting effect and efficiency of the glass body 3. Therefore, this embodiment of the invention sets the second gap D2 within a suitable size range, thereby improving the frosting effect and efficiency of the glass body 3 while avoiding excessive circuit load, protecting the power supply circuit, improving the safety of the heating wires 4, and increasing production yield. The second gap D2 can be, but is not limited to, 27.5mm, 27.6mm, 27.7mm, 27.8mm, 27.9mm, 28.0mm, 28.1mm, 28.2mm, 28.3mm, 28.4mm or 28.5mm, etc., and the embodiments of this utility model do not make specific limitations.

[0072] At least one of the heating wire 4 and antenna 5 is disposed on the glass body 3 using silver paste printing, coating, or wire embedding. Thus, both the heating wire 4 and antenna 5 can form an integral structure, thereby improving the structural stability and reliability of the heating wire 4 and antenna 5 and avoiding the risk of connection point failure due to vibration or thermal expansion and contraction. This fully integrated printing solution reduces manufacturing costs and is suitable for mass production. Exemplarily, in this embodiment, both the heating wire 4 and antenna 5 are disposed on the glass body 3 using silver paste printing. Of course, in some embodiments, the heating wire 4 and antenna 5 can also be disposed in segments; this embodiment of the present invention does not impose specific limitations.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
