Description

Technical Field

[0001] This application relates to the field of automotive window glass components technology, particularly glass assemblies and vehicles. Background Technology

[0002] Currently, with the development of intelligent vehicles, more and more electronic devices are being used in cars. Some of these devices need to be installed on the glass itself, such as rain sensors, Advanced Driver Assistance Systems (ADAS), and dashcams. In existing technology, electronic devices installed on the glass are often connected to the control system via wiring harnesses led out from the vehicle body. These wiring harnesses are external to the glass and require fixing with wiring harness accessories, then concealed by the headliner or exterior trim panels, resulting in a complex wiring harness layout. Therefore, the wiring harness accessories fixed to the glass can obstruct the view of the glass, affecting the user experience, and the assembly process is cumbersome. Summary of the Invention

[0003] The purpose of this application is to provide a glass assembly and vehicle that simplifies the assembly process of the glass assembly, expands the field of vision of the glass body, and enhances the customer's user experience.

[0004] The first aspect of this application provides a glass assembly, the glass assembly including a glass body and a transmission part disposed on the glass body;

[0005] The transmission unit includes a transmission layer, a first shielding layer, and a second shielding layer. The transmission layer is located between the first shielding layer and the second shielding layer. The first shielding layer and the transmission layer are electrically insulated from each other, and the second shielding layer and the transmission layer are electrically insulated from each other. The transmission layer, the first shielding layer, and the second shielding layer are all electrical conductors.

[0006] It is understood that by providing a transmission section on the glass body, signals between the vehicle's control system and electronic equipment can be transmitted back and forth through the transmission section. Compared to the prior art that uses wire harnesses to transmit signals between electronic equipment and the control system, the transmission section in this embodiment can be printed on the surface of the glass body, thus avoiding the need to provide wire harness accessories on the glass body to fix the wire harness, and avoiding the need to design separate brackets to fix the wire harness. Therefore, the assembly process of the glass assembly is simplified, the field of view of the glass body is expanded, and the customer's user experience is improved.

[0007] In one possible implementation, the transmission layer, the first shielding layer, and the second shielding layer are all conductive pastes printed on the glass body.

[0008] In one possible implementation, the transmission unit includes a first insulating layer and a second insulating layer, wherein the first insulating layer is located between a first shielding layer and a transmission layer, and the first shielding layer and the transmission layer are electrically insulated from each other through the first insulating layer; and the second insulating layer is located between a second shielding layer and a transmission layer, and the second shielding layer and the transmission layer are electrically insulated from each other through the second insulating layer.

[0009] In one possible implementation, along the width direction of the transmission section, the widths of the first insulating layer and the second insulating layer are respectively greater than or equal to the width of the transmission layer.

[0010] In one possible implementation, the first shielding layer and the second shielding layer are located on the same surface of the glass body, and the first shielding layer, the first insulating layer, the transmission layer, the second insulating layer and the second shielding layer are stacked in sequence.

[0011] In one possible implementation, the first shielding layer and the second shielding layer are located on different surfaces of the glass body, and at least a portion of the glass body serves as either the first insulating layer or the second insulating layer.

[0012] In one possible implementation, the glass body includes an outer glass plate, an intermediate layer, and an inner glass plate. The intermediate layer is sandwiched between the outer glass plate and the inner glass plate. The transmission layer is located on the surface of the inner glass plate opposite to the outer glass plate. The first shielding layer is located between the outer glass plate and the inner glass plate. The inner glass plate serves as a first insulating layer. The second shielding layer is disposed on the side of the transmission layer opposite to the inner glass plate. The second insulating layer is disposed between the transmission layer and the second shielding layer.

[0013] In one possible implementation, the transmission unit further includes a connector, and at least one side of the first shielding layer and the second shielding layer are electrically connected through the connector along the width direction of the transmission unit.

[0014] In one possible implementation, along the width direction of the transmission section, the opposite sides of the first shielding layer are electrically connected to the opposite sides of the second shielding layer, and thus enclose the transmission layer.

[0015] In one possible implementation, the glass assembly further includes a connector, which includes a transmission layer connection end and a shielding layer connection end. The transmission layer connection end and the shielding layer connection end are electrically insulated from each other. The transmission layer connection end is electrically connected to the transmission layer, and the shielding layer connection end is electrically connected to the first shielding layer and / or the second shielding layer.

[0016] In one possible implementation, the shielding layer connection is arranged circumferentially around the transmission layer connection.

[0017] In one possible implementation, along the width direction of the transmission section, the widths of the first shielding layer and the second shielding layer are respectively greater than or equal to the width of the transmission layer.

[0018] In one possible implementation, the glass assembly further includes a shielding layer disposed on the glass body, the orthographic projection of the shielding layer on the glass body covering the orthographic projection of the transmission portion on the glass body, so that the transmission portion is not visible in a direction on at least one side of the glass body.

[0019] A second aspect of this application provides a vehicle, including a vehicle body and a glass assembly as described above, the glass assembly being connected to the vehicle body;

[0020] The vehicle also includes a control system and electronic equipment, which are electrically connected via a transmission section of the glass assembly.

[0021] The beneficial effects of this application are as follows: By providing a transmission section on the inner surface of the glass body, signals between the vehicle's control system and electronic equipment can be transmitted back and forth through the transmission section. Compared to the prior art using wire harnesses to transmit signals between electronic equipment and the control system, the transmission section in this application embodiment can be printed on the surface of the glass body. This not only avoids the need to provide wire harness accessories on the glass body to fix the wire harness, but also avoids the need to design separate brackets to fix the wire harness. Therefore, it simplifies the assembly process of the glass assembly, expands the field of view of the glass body, and improves the user experience. By providing a first shielding layer and a second shielding layer to shield the signals in the transmission layer, it is possible to prevent signals outside the glass body from interfering with the signals transmitted in the transmission layer, and also to prevent the signals transmitted in the transmission layer from leaking out and interfering with nearby electronic equipment. By providing a shielding layer, the transmission layer, the first shielding layer, and the second shielding layer can be shielded, thereby improving the aesthetics of the glass assembly and ensuring the appearance requirements of the glass assembly are met.

Detailed Implementation

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 The vehicle 1000 includes a body 200 and a glass assembly 100, with the glass assembly 100 mounted on the body 200. The body 200 is the main body of the automobile and may also include doors. The glass assembly 100 includes a transmission unit 10. The vehicle 1000 also includes electronic equipment, a control system (not shown), and a power system (not shown), all located inside the body 200. The control system and electronic equipment are electrically connected to the power system, which supplies power to the control system and electronic equipment. The electronic equipment is electrically connected to the control system via the transmission unit 10, which transmits signals between the control system and the electronic equipment.

[0033] It should be noted that the electronic devices may or may not be integrated into the glass assembly 100. The electronic devices may be rain sensors, ADAS-related devices, or dashcams, or other electronic devices that require signal transmission with the control system; this application does not impose specific limitations on this. The types of signals that the transmission unit 10 can transmit include, but are not limited to, LIN (Local Interconnect Network) signals and CAN (Controller Area Network) signals.

[0034] In some embodiments of this application, the glass assembly 100 includes a glass body 30 and a transmission section 10 disposed on the glass body 30;

[0035] The transmission unit 10 includes a transmission layer 11, a first shielding layer 12, and a second shielding layer 13. The transmission layer 11 is located between the first shielding layer 12 and the second shielding layer 13. The first shielding layer 12, the transmission layer 11, and the second shielding layer 13 are stacked sequentially. The first shielding layer 12 and the transmission layer 11 are electrically insulated from each other, and the second shielding layer 13 and the transmission layer 11 are electrically insulated from each other. The transmission layer 11, the first shielding layer 12, and the second shielding layer 13 are all electrical conductors.

[0036] The transmission layer 11, the first shielding layer 12, and the second shielding layer 13 can be stacked on the same surface of the glass body 30, or they can be stacked on different surfaces of the glass body 30. For example, when the glass body 30 is a single-layer glass plate, the first shielding layer 12, the transmission layer 11, and the second shielding layer 13 can be stacked sequentially on the inner or outer surface of the single-layer glass plate. Alternatively, the first shielding layer 12 can be disposed on the outer surface of the single-layer glass plate, and the transmission layer 11 and the second shielding layer 13 can be stacked sequentially on the inner or outer surface of the single-layer glass plate. Similarly, when the glass body 30 is laminated glass, the first shielding layer 12, the transmission layer 11, and the second shielding layer 13 can be stacked sequentially on the inner or outer surface of the laminated glass. Alternatively, the first shielding layer 12 can be located between the inner and outer glass plates of the laminated glass, and the transmission layer 11 and the second shielding layer 13 can be stacked sequentially on the inner or outer surface of the laminated glass.

[0037] Furthermore, in some embodiments of this application, in order to ensure that the first shielding layer 12 and the second shielding layer 13 have a good signal shielding effect on the transmission layer 11, the widths of the first shielding layer 12 and the second shielding layer 13 are respectively greater than or equal to the width of the transmission layer 11 along the width direction of the transmission section 10.

[0038] The transmission layer 11, the first shielding layer 12, and the second shielding layer 13 can use the same electrical conductor material, or they can use different electrical conductor materials, such as metallic elements, oxides or alloys, or other non-metallic conductive materials, like silver or copper. In some embodiments of this application, the transmission layer 11, the first shielding layer 12, and the second shielding layer 13 are all conductive pastes printed on the glass body 30, such as silver paste, copper paste, platinum paste, etc.

[0039] In some embodiments of this application, the transmission unit 10 further includes a first insulating layer 14 and a second insulating layer 15. The first insulating layer 14 and the second insulating layer 15 mainly serve to electrically insulate the transmission layer 11 from the first shielding layer 12 and the second shielding layer 13. Therefore, in some embodiments of this application, the first insulating layer 14 and the second insulating layer 15 are both printed insulating pastes, such as ceramic ink. The first insulating layer 14 is located between the first shielding layer 12 and the transmission layer 11, and the first shielding layer 12 and the transmission layer 11 are electrically insulated through the first insulating layer 14. The second insulating layer 15 is located between the second shielding layer 13 and the transmission layer 11, and the second shielding layer 13 and the transmission layer 11 are electrically insulated through the second insulating layer 15.

[0040] The positions of the first insulating layer 14 and the second insulating layer 15 can vary depending on the positions of the first shielding layer 12 and the second shielding layer 13. For example, in some embodiments, the first shielding layer 12 and the second shielding layer 13 are located on the same surface of the glass body 30, in which case the first shielding layer 12, the first insulating layer 14, the transmission layer 11, the second insulating layer 15, and the second shielding layer 13 are stacked sequentially. In other embodiments, when the first shielding layer 12 and the second shielding layer 13 are located on different surfaces of the glass body 30, at least a portion of the glass body 30 can serve as either the first insulating layer 14 or the second insulating layer 15. For example, when the glass body 30 is laminated glass, the first shielding layer 12 is located between the inner and outer glass plates of the laminated glass, and the transmission layer 11 and the second shielding layer 13 are stacked sequentially on the inner or outer surface of the laminated glass. In this case, the glass plate located between the first shielding layer 12 and the transmission layer 11 in the laminated glass can serve as the first insulating layer 14, and the second insulating layer 15 is ceramic ink printed between the transmission layer 11 and the second shielding layer 13.

[0041] In some embodiments of this application, in order to ensure good electrical insulation between the transmission layer 11 and the first shielding layer 12 and the second shielding layer 13, the widths of the first insulating layer 14 and the second insulating layer 15 are greater than or equal to the width of the transmission layer 11 along the width direction of the transmission section 10.

[0042] Please refer to the following: Figure 2 and Figure 3 This application provides a first embodiment of a glass assembly 100. In this embodiment, the glass assembly 100 includes a glass body 30, a transmission section 10, and a connector section, wherein, as in... Figure 2 and Figure 3 In the illustrated embodiment, the connector may have a first connector 21 and a second connector 22 connected to both ends of the transmission unit 10. The transmission unit 10, the first connector 21, and the second connector 22 are all fixed to the glass body 30.

[0043] It is understood that the glass assembly 100 can be provided with multiple transmission units 10, and each transmission unit 10 has a first connector 21 and a second connector 22 connected to both ends. Multiple transmission units 10 can respectively transmit signals between the control system and multiple different electronic devices. This embodiment of the application only uses one transmission unit 10 and the first connector 21 and second connector 22 connected to both ends of the transmission unit 10 as an example for explanation.

[0044] In this embodiment, the glass body 30 is a single-layer glass plate. The glass body 30 includes an inner surface 311 and an outer surface 312, which are arranged opposite to each other along the thickness direction of the glass body 30, wherein the inner surface 311 faces the interior of the vehicle 1000.

[0045] It should be noted that the glass body 30 can be automotive glass, such as a windshield, rear window, sunroof, or glass installed in other locations. This application does not impose specific limitations on the installation location of the glass body 30. The glass body 30 can be a flat plate, or it can be curved or arc-shaped. The shape of the glass body 30 is not limited to the shapes described above; it can be any shape that meets the usage requirements. This application does not impose specific limitations on the shape of the glass body 30.

[0046] Please see Figure 3 In this embodiment, the transmission section 10 has a linear structure. The transmission section 10 includes a transmission layer 11, which is stacked on the inner surface 311 of the glass body 30. The transmission layer 11 is conductive. Specifically, the material of the transmission layer 11 is silver paste. In other embodiments, the transmission layer 11 may also be copper paste or other materials with conductive properties.

[0047] It should be noted that the transmission unit 10 can be a linear structure of any shape, such as a straight line or a curved line. The specific configuration can be determined according to the actual required signal transmission path. The transmission unit 10 provided in this embodiment only considers the signal transmission needs of the electronic device and does not consider the function of shielding signals, thus it is suitable for low-frequency signal transmission.

[0048] In some embodiments of this application, the glass assembly 100 further includes a shielding layer disposed on the glass body 30. The orthographic projection of the shielding layer on the glass body 30 covers the transmission section 10, making the transmission section 10 invisible from at least one side of the glass body 30. For example, the shielding layer is disposed on both the outer and inner surfaces of the glass body 30, so that the transmission section 10 is located between the two shielding layers, thereby making the transmission section 10 invisible from both the inner and outer sides of the glass body 30. Alternatively, the shielding layer may be disposed only on the outer or inner surface of the glass body 30, making the transmission section 10 invisible from either the outer or inner side of the glass body 30. Furthermore, when the glass body 30 is laminated glass, the shielding layer may also be disposed between the inner and outer glass plates of the laminated glass, thereby achieving the same shielding effect on the transmission section 10.

[0049] In one embodiment, a shielding layer is stacked on the surface of the transmission layer 11 facing away from the inner surface 311 of the glass body 30. The shielding layer is insulating. Along the width direction of the transmission section 10, the width of the shielding layer is greater than the width of the transmission layer 11. Specifically, the shielding layer is made of black ceramic ink.

[0050] Please refer to the following: Figure 2 and Figure 3 In this embodiment, the connector includes a first connector 21 and a second connector 22. Specifically, the first connector 21 and the second connector 22 are solder joints. The first connector 21 and the second connector 22 are respectively connected to both ends of the transmission unit 10 and electrically connected to both ends of the transmission layer 11. Specifically, the first connector 21 and the second connector 22 are soldered to both ends of the transmission unit 10. The first connector 21 is used for electrical connection with the control system, and the second connector 22 is used for electrical connection with electronic equipment.

[0051] It should be noted that the structures of the first connector 21 and the second connector 22 can be the same or different; when the structures of the first connector 21 and the second connector 22 are the same, their dimensions can be the same or different. The specific dimensions are determined according to actual usage requirements. In other embodiments, the first connector 21 and the second connector 22 can also be other components, as long as the transmission unit 10 can be electrically connected to electronic equipment or a control system.

[0052] In this embodiment, the vehicle 1000 further includes a first signal line and a second signal line, both located inside the vehicle body 200. One end of the first signal line is electrically connected to the control system, and the other end is used for electrical connection to the first connector 21. One end of the second signal line is electrically connected to an electronic device, and the other end is used for electrical connection to the second connector 22.

[0053] It is understood that by using the transmission unit 10 provided in this embodiment and the first connector 21 and the second connector 22 disposed at both ends of the transmission unit 10, signals between the control system and the electronic equipment can be transmitted back and forth through the transmission unit 10 and the first connector 21 and the second connector 22 disposed at both ends of the transmission unit 10. Compared with the prior art that uses wire harnesses to transmit signals between electronic equipment and the control system, the transmission unit 10 of this embodiment is printed on the inner surface 311 of the glass body 30, which not only avoids the need to set wire harness accessories on the glass body 30 to fix the wire harness, but also avoids the need to design a separate bracket to fix the wire harness. Therefore, the assembly process of the glass assembly 100 is simplified, and the field of view of the glass body 30 is expanded, improving the user experience.

[0054] Furthermore, in the glass assembly 100 provided in this embodiment, the transmission part 10 for transmitting signals is located on the inner surface 311 of the glass body 30, eliminating the need for opening holes in local locations of the glass body 30, thus ensuring the rigidity of the glass body 30.

[0055] In one embodiment, an electronic device is integrated into a glass assembly 100. The glass assembly 100 also includes a power supply unit (not shown). The power supply unit includes a positive electrode, a negative electrode, and a conductive layer, all of which are stacked on the inner surface 311 of the glass body 30. The conductive layer has a linear structure, with the positive and negative electrodes connected to its two ends, respectively. The positive and negative electrodes are electrically connected to the positive and negative electrodes of a power supply system, respectively. The conductive layer electrically connects the positive electrode of the electronic device to the positive electrode of the power supply unit and the negative electrode of the electronic device to the negative electrode of the power supply unit, forming a power supply circuit. Specifically, the positive electrode, negative electrode, and conductive layer are all made of silver paste. The power supply unit also includes a cover layer, which is stacked on the side of the positive electrode, negative electrode, and conductive layer facing away from the inner surface 311 of the glass body 30, to cover the positive electrode, negative electrode, and conductive layer, thereby improving the aesthetics of the glass assembly 100.

[0056] Please see Figure 4 and Figure 5 This application provides a second embodiment of the glass assembly 100. The difference between this embodiment and the first embodiment is that the transmission section 10 further includes a shielding layer and an insulating layer, the structure of the first connector 21 is different, and the structure of the second connector 22 is different.

[0057] The transmission unit 10 includes a transmission layer 11, a first shielding layer 12, a second shielding layer 13, a first insulating layer 14, and a second insulating layer 15. The first shielding layer 12, the first insulating layer 14, the transmission layer 11, the second insulating layer 15, and the second shielding layer 13 are sequentially stacked on the inner surface 311 of the glass body 30. The first shielding layer 12, the transmission layer 11, and the second shielding layer 13 are conductive, while the first insulating layer 14 and the second insulating layer 15 are insulating.

[0058] Along the extension direction of the transmission section 10, the first shielding layer 12, the first insulating layer 14, the transmission layer 11, the second insulating layer 15, and the second shielding layer 13 have the same length (with certain dimensional tolerances allowed). Along the width direction of the transmission section 10, the width of the first shielding layer 12 is greater than the width of the transmission layer 11. The opposite sides of the second shielding layer 13 are respectively attached to the opposite sides of the first shielding layer 12 to form an electrical connection, and thus enclose the transmission layer 11 to improve signal shielding effectiveness. Especially for high-frequency signals with a frequency range ≥100MHz, the enclosed and grounded enclosure of the transmission layer 11 by the second shielding layer 13 and the first shielding layer 12 achieves a better signal shielding effect. Figure 4 The connection between the first shielding layer 12 and the second shielding layer 13 on both sides is shown as a connection portion 133. In some embodiments, the first shielding layer 12 and the second shielding layer 13 are formed by printing, and the connection portion 133 is naturally formed on both sides so as not to have an additional physical entity. Alternatively, an additional connection portion 133 can be inserted between the first shielding layer 12 and the second shielding layer 13 to form an electrical connection between the first shielding layer 12 and the second shielding layer 13 and to form a wrapping around the transmission layer 11. This application does not make specific limitations in this regard.

[0059] Furthermore, in some embodiments, the first shielding layer 12 and the second shielding layer 13 may not completely enclose the transmission layer 11. The first shielding layer 12 and the second shielding layer 13 are grounded via conductors, which can still meet the signal shielding requirements at certain signal frequencies. The first shielding layer 12 and the second shielding layer 13 are used to shield signals. A first insulating layer 14 is located between the first shielding layer 12 and the transmission layer 11, used to electrically insulate the first shielding layer 12 and the transmission layer 11. The width of the first insulating layer 14 is larger than the width of the transmission layer 11 and smaller than the width of the first shielding layer 12. A second insulating layer 15 is located between the second shielding layer 13 and the transmission layer 11, used to electrically insulate the second shielding layer 13 and the transmission layer 11. Along the width direction of the transmission section 10, the opposite sides of the second insulating layer 15 are bonded to the opposite sides of the first insulating layer 14 to form electrical insulation, and enclose the transmission layer 11 to improve the insulation effect. Figure 4 The connection between the first insulating layer 14 and the second insulating layer 15 on both sides is shown as an insulating portion 153. In some embodiments, the first insulating layer 14 and the second insulating layer 15 are formed by printing, and the insulating portions 153 are naturally formed on both sides without the need for additional physical insulating portions. Alternatively, the first insulating layer 14 and the second insulating layer 15 can be wrapped around the transport layer 11 by inserting an additional insulating portion 153 between them. This application does not impose any specific limitations on this.

[0060] Along the extending direction of the transmission section 10, the two ends of the second insulating layer 15 are respectively provided with a first opening 151 and a second opening. The two ends of the second shielding layer 13 are respectively provided with a third opening 131 and a fourth opening. Along the thickness direction of the transmission section 10, the first opening 151 and the third opening 131 are opposite to each other and connected; the second opening and the fourth opening are opposite to each other and connected. One end of the transmission layer 11 is exposed through the first opening 151 and the connected third opening 131, and the other end is exposed through the second opening and the connected fourth opening.

[0061] The first shielding layer 12 and the second shielding layer 13 are made of silver paste. The sheet resistance of the transmission layer 11, the first shielding layer 12, and the second shielding layer 13 can be adjusted by changing the silver paste ratio and linewidth. For example, the sheet resistance of the transmission layer 11, the first shielding layer 12, and the second shielding layer 13 are all 3–7 Ω / sq. The first insulating layer 14 and the second insulating layer 15 are made of black ceramic ink. In other embodiments, the transmission layer 11, the first shielding layer 12, and the second shielding layer 13 can be made of copper paste or other conductive materials.

[0062] It should be noted that each layer of the transmission section 10 is formed by screen printing. In other embodiments, the layers of the transmission section 10 may also be formed by other methods such as relief printing.

[0063] The connector includes a transmission layer connection end and a shielding layer connection end, which are electrically insulated from each other. The transmission layer connection end is electrically connected to the transmission layer 11 for signal transmission, and the shielding layer connection end is electrically connected to the first shielding layer 12 and / or the second shielding layer 13 to extend the signal shielding effect of the first shielding layer 12 and / or the second shielding layer 13. In some further embodiments, the shielding layer connection end is arranged circumferentially around the transmission layer connection end to form good signal shielding for the transmission layer connection end.

[0064] Please refer to the following: Figure 4 and Figure 5In this embodiment, the connector includes a first connector 21 and a second connector 22. The first connector 21 includes a first connector 211 (i.e., the transmission layer connection end) and a second connector 212 (i.e., the shielding layer connection end). The second connector 212 is circumferentially arranged around the first connector 211, and is electrically insulated from the first connector 211. The second connector includes a third connector (i.e., the transmission layer connection end) and a fourth connector (i.e., the shielding layer connection end). The fourth connector is circumferentially arranged around the third connector, and is electrically insulated from the third connector. The first connector 21 and the second connector 22 are respectively connected to the two ends of the transmission section 10. The first connector 21 is used for electrical connection with the control system. The second connector 22 is used for electrical connection with electronic equipment. Specifically, the first connector 21 and the second connector 22 are respectively welded to the two ends of the transmission section 10. The first connector 211 (i.e., the transmission layer connection end) of the first connector 21 passes through the first opening 151 and the communicating third opening 131 and is electrically connected to the transmission layer 11. The second connector 212 (i.e., the shielding layer connection end) is electrically connected to the second shielding layer 13. The third connector (i.e., the transmission layer connection end) of the second connector 22 passes through the second opening and the communicating fourth opening and is electrically connected to the transmission layer 11. The fourth connector (i.e., the shielding layer connection end) is electrically connected to the second shielding layer 13.

[0065] It should be noted that, along the extension direction of the transmission section 10, the connection method between the two ends of the transmission section 10 and the first connector 21 and the second connector 22 is the same. In this embodiment, only the connection structure between one end of the transmission section 10 and the first connector 21 is used as an example for explanation.

[0066] In this embodiment, one end of the first signal line is electrically connected to the control system, and the other end is electrically connected to the first connector 21. One end of the second signal line is electrically connected to the electronic device, and the other end is electrically connected to the second connector 22.

[0067] It should be noted that the first connector 21 can be electrically connected to the first signal line by means of soldering or the like, and the second connector 22 can be electrically connected to the second signal line by means of soldering or the like. This application does not impose strict limitations on the connection method between the first connector 21 and the first signal line, or the connection method between the second connector 22 and the second signal line.

[0068] It is understood that in this embodiment, by providing a first shielding layer 12 and a second shielding layer 13 on the sides of the transmission layer 11 near and away from the glass body 30, respectively, and by electrically connecting and grounding the first shielding layer 12 and the second shielding layer 13, the first shielding layer 12 and the second shielding layer 13 can shield the signals transmitted in the transmission layer 11. This prevents external signals from the glass body 30 from interfering with the signals transmitted in the transmission layer 11, and also prevents the signals transmitted in the transmission layer 11 from leaking out and interfering with nearby electronic devices. Furthermore, the first connector 211 of the first connector 21 is electrically connected to the transmission layer 11, and the second connector 212 is electrically connected to the second shielding layer 13. The connection method between the first connector 21 and the transmission unit 10 also ensures the signal shielding requirements. The third connector of the second connector 22 is electrically connected to the transmission layer 11, and the fourth connector is electrically connected to the second shielding layer 13. The connection method between the second connector 22 and the transmission unit 10 also ensures the signal shielding requirements.

[0069] Furthermore, by screen printing silver paste to form the first shielding layer 12, the transmission layer 11, and the second shielding layer 13, the first shielding layer 12, the transmission layer 11, and the second shielding layer 13 can have the advantages of high printing accuracy, strong adhesion, and resistance to wear. Moreover, the silver lines in the silver paste are not easy to break, which can ensure the conductivity of the first shielding layer 12, the transmission layer 11, and the second shielding layer 13.

[0070] In one embodiment, the glass assembly 100 further includes a shielding layer disposed on the glass body 30. Specifically, the shielding layer may include a first shielding layer and a second shielding layer. The first shielding layer is located between the first shielding layer 12 and the glass body 30. Along the width direction of the transmission section 10, the width of the first shielding layer is greater than or equal to the width of the first shielding layer 12. The second shielding layer is located on the side of the second shielding layer 13 facing away from the inner surface 311 of the glass body 30. Along the width direction of the transmission section 10, the width of the second shielding layer is greater than or equal to the width of the second shielding layer 13. The first opening 151, the second opening of the second insulating layer 15, and the third opening 131 and fourth opening of the second shielding layer 13 are all exposed in the second shielding layer. The first and second shielding layers are made of black ceramic ink. The first and second shielding layers are used to shield the transmission layer 11, the first shielding layer 12, and the second shielding layer 13, improving the aesthetics of the glass assembly 100 and ensuring the appearance requirements of the glass assembly 100. In other embodiments, only the first occlusion layer or only the second occlusion layer may be provided.

[0071] Please refer to the following: Figure 6 and Figure 7 This application provides a third embodiment of the glass assembly 100. The difference between this embodiment and the second embodiment is that the glass body 30 is laminated glass, and the structure of the transmission section 10 is different.

[0072] The glass body 30 includes an outer glass panel 33, an intermediate layer 32, and an inner glass panel 31, with the intermediate layer 32 stacked between the outer glass panel 33 and the inner glass panel 31. The inner glass panel 31 includes an inner surface 311 and an outer surface 312, which are disposed opposite to each other along the thickness direction of the inner glass panel 31. The inner surface 311 faces the interior of the vehicle 1000, and the outer surface 312 faces the intermediate layer 32.

[0073] In this embodiment, the transmission unit 10 includes a first shielding layer 12, a transmission layer 11, a second insulating layer 16, a second shielding layer 13, and two connectors 18. The first shielding layer 12 is sandwiched between the intermediate layer 32 and the outer surface 312 of the inner glass plate 31. The transmission layer 11 is stacked on the inner surface 311 of the inner glass plate 31. The second insulating layer 16 is stacked on the side of the transmission layer 11 facing away from the inner glass plate 31. The second shielding layer 13 is stacked on the side of the second insulating layer 16 facing away from the inner glass plate 31. At this time, the portion of the inner glass plate 31 located between the first shielding layer 12 and the transmission layer 11 serves as the first insulating layer. Along the width direction of the transmission unit 10, the two connectors 18 are located on opposite sides of the transmission layer 11. One connector 18 is electrically connected to one side of the first shielding layer 12 and one side of the second shielding layer 13, and the other connector 18 is electrically connected to the other side of the first shielding layer 12 and the other side of the second shielding layer 13. Along the width direction of the transmission unit 10,

[0074] In some embodiments, the opposite sides of the second insulating layer 16 are bonded to the surface of the inner glass plate 31 to form electrical insulation and to encapsulate the transmission layer 11, thereby improving the insulation effect. Figure 6 and Figure 7The connection between the second insulating layer 16 and both sides of the inner glass plate 31 is shown as an insulating portion 163. In some embodiments, the second insulating layer 16 is formed by printing, and the insulating portions 163 are naturally formed on both sides without the need for additional physical insulating portions. Alternatively, additional insulating portions 163 can be inserted between the second insulating layer 16 and the inner glass plate 31 to form a wrapping around the transmission layer 11. This application does not impose specific limitations on this. The first shielding layer 12, the transmission layer 11, the second shielding layer 13, and the two connectors 18 are all conductive, while the second insulating layer 16 is insulating. The first shielding layer 12, the second shielding layer 13, and the two connectors 18 together enclose the transmission layer 11, improving the signal shielding effect of the first shielding layer 12 and the second shielding layer 13. Simultaneously, the connectors 18 facilitate grounding the first shielding layer 12 and the second shielding layer 13 together. This is particularly effective for high-frequency signals with a frequency range ≥100MHz, where the enclosed structure and grounding of the transmission layer 11 by the first shielding layer 12, the second shielding layer 13, and the two connectors 18 achieves good signal shielding. Furthermore, in some embodiments, the first shielding layer 12 and the second shielding layer 13 can be electrically connected on only one side via the connectors 18, still meeting the signal shielding requirements for certain communication frequencies. Further, in some embodiments, the connectors 18 may not be provided between the first shielding layer 12 and the second shielding layer 13; instead, they can be grounded separately via conductors, still meeting the signal shielding requirements for certain signal frequencies.

[0075] Along the extension direction of the transmission section 10, the first shielding layer 12, the transmission layer 11, the second insulating layer 16, and the second shielding layer 13 have the same length (with a certain dimensional tolerance allowed). Along the width direction of the transmission section 10, the opposite sides of the first shielding layer 12 and the opposite sides of the second shielding layer 13 are electrically connected to each other via two connectors 18, and both the first shielding layer 12 and the second shielding layer 13 are grounded simultaneously. The first shielding layer 12 and the second shielding layer 13 are used to shield signals. The first shielding layer 12 and the transmission layer 11 are located on opposite sides of the inner glass plate 31 along its thickness direction, and the inner glass plate 31 electrically insulates the first shielding layer 12 and the transmission layer 11. The second insulating layer 16 is located between the second shielding layer 13 and the transmission layer 11, and is used to electrically insulate the second shielding layer 13 and the transmission layer 11.

[0076] Along the extending direction of the transmission section 10, the two ends of the second insulating layer 16 are respectively provided with a first opening 161 and a second opening. The two ends of the second shielding layer 13 are respectively provided with a third opening 131 and a fourth opening. Along the thickness direction of the transmission section 10, the first opening 161 and the third opening 131 are opposite to each other and connected; the second opening and the fourth opening are opposite to each other and connected. One end of the transmission layer 11 is exposed through the first opening 161 and the connected third opening 131, and the other end is exposed through the second opening and the connected fourth opening.

[0077] The transmission layer 11, the first shielding layer 12, and the second shielding layer 13 are made of silver paste. The sheet resistance of the transmission layer 11, the first shielding layer 12, and the second shielding layer 13 can be adjusted by changing the silver paste ratio and linewidth. For example, the sheet resistance of the transmission layer 11, the first shielding layer 12, and the second shielding layer 13 is all 3Ω / sq. The second insulating layer 16 is made of black ceramic ink. Both connectors 18 are copper foil.

[0078] It should be noted that in this embodiment, all layers of the transmission unit 10 are formed by screen printing. The two connectors 18 are connected to the first shielding layer 12 and the second shielding layer 13 by welding. In other embodiments, the layers of the transmission unit 10 can also be formed by other methods such as relief printing; the materials of the transmission layer 11, the first shielding layer 12 and the second shielding layer 13 can also be copper paste or other conductive materials; the two connectors 18 can also be connected to the first shielding layer 12 and the second shielding layer 13 by other methods.

[0079] In one embodiment, the glass assembly 100 further includes a shielding layer disposed on the glass body 30. Specifically, the shielding layer may include a first shielding layer and a second shielding layer. The first shielding layer is located between the first shielding layer 12 and the intermediate layer 32. Along the width direction of the transmission section 10, the width of the first shielding layer is greater than or equal to the width of the first shielding layer 12. The second shielding layer is located on the side of the second shielding layer 13 facing away from the inner surface 311 of the glass body 30. Along the width direction of the transmission section 10, the width of the second shielding layer is greater than or equal to the width of the second shielding layer 13. The first and second shielding layers are made of ink material. The first and second shielding layers are used to shield the transmission layer 11, the first shielding layer 12, and the second shielding layer 13, improving the aesthetics of the glass assembly 100 and ensuring the appearance requirements of the glass assembly 100.

[0080] Please refer to the following: Figure 5 and Figure 6In this embodiment, the first connector 21 and the second connector 22 are respectively connected to both ends of the transmission unit 10. Specifically, the first connector 21 and the second connector 22 are welded to both ends of the transmission unit 10. The first connector 211 (i.e., the transmission layer connection end) of the first connector 21 passes through the first opening 161 and the communicating third opening 131 and is electrically connected to the transmission layer 11, and the second connector 212 (i.e., the shielding layer connection end) is electrically connected to the second shielding layer 13. The third connector (i.e., the transmission layer connection end) of the second connector 22 passes through the second opening and the communicating fourth opening and is electrically connected to the transmission layer 11, and the fourth connector (i.e., the shielding layer connection end) is electrically connected to the second shielding layer 13.

[0081] It should be noted that, along the extension direction of the transmission section 10, the connection method between the two ends of the transmission section 10 and the first connector 21 and the second connector 22 is the same. In this embodiment, only the connection structure between one end of the transmission section 10 and the first connector 21 is used as an example for explanation.

[0082] One end of the first signal line is electrically connected to the control system, and the other end is electrically connected to the first connector 21. One end of the second signal line is electrically connected to the electronic device, and the other end is used to electrically connect to the second connector 22.

[0083] It is understood that in this embodiment, the transmission layer 11 is stacked on the inner surface 311 of the inner glass plate 31, and the first shielding layer 12 is disposed on the surface of the inner glass plate 31 facing away from the transmission layer 11. The inner glass plate 31 and the first shielding layer 12 can be used to electrically insulate the transmission layer 11, which simplifies the structure of the transmission section 10 and saves the cost of the glass assembly 100.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. 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 application. Therefore, the content of this specification should not be construed as a limitation of this application.
