[0018] Hereinafter, the technical solutions of the embodiments of the present application will be described clearly and completely with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0019] The terms "first", "second", etc. in the specification, claims and the above drawings of this application are intended to distinguish different objects, not to describe a particular order. Also, the terms "comprise", "have" and any variations thereof are intended to cover, not exclude, the inclusion of other components. For example, a process, method, system, product, or device that includes a series of operations or units is not limited to the listed operations or units, and may optionally include unlisted operations or units, or may optionally include other operations or units inherent to those processes, methods, products, or devices.

[0020] An "embodiment" referred to in this specification means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the present application. The wording anywhere in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art can understand, explicitly or implicitly, that an embodiment described in this specification can be combined with other embodiments when there is no contradiction between at least two embodiments combined.

[0021] 1 and 2, the present application provides a vehicle 1. The vehicle 1 may be, but is not limited to, a passenger car, a multi-purpose vehicle (MPV), a sport / suburban utility vehicle (SUV), an off-road vehicle (ORV), a pickup truck, a minivan, a bus, a truck, and the like.

[0022] The vehicle 1 includes a vehicle body 2 and an antenna system 3 described in the following embodiments. The antenna system 3 is attached to the vehicle body 2, and an in-vehicle unit 5 included in the antenna system 3 is electrically connected to the vehicle body 2 via a second cable 4.

[0023] The vehicle body 2 refers to at least a part of the vehicle 1, or includes at least some structural components and electronic devices of the vehicle 1. For example, the vehicle body 2 may include a frame, a windshield, a seat, a central control screen, and the like.

[0024] The antenna system 3 is configured to receive or transmit electromagnetic waves, and the in-vehicle unit 5 included in the antenna system 3 is electrically connected to the vehicle body 2 via a second cable 4 (a power line 41 and a communication line 42). In other words, the in-vehicle unit 5 is connected to and communicates with the entire vehicle network via the second cable 4, and the vehicle 1 communicates with the outside via the antenna system 3.

[0025] 2 and 3, the present application further provides an antenna system 3. The antenna system 3 includes an on-vehicle unit 5 and an antenna assembly 6 described in any of the following embodiments. A first cable 250 included in the antenna assembly 6 is electrically connected to the on-vehicle unit 5. The on-vehicle unit 5 can be installed in a position such as a windshield, frame, or ceiling of the vehicle 1, and is not limited by the present application.

[0026] The on-board unit 5 (OBU) is configured to generate a radio frequency signal. The radio frequency signal can be transmitted to the antenna assembly 6 via the first cable 250, and the antenna assembly 6 can generate and radiate a corresponding electromagnetic wave into the surrounding space. This process is the process of the antenna system 3 transmitting the electromagnetic wave. Of course, the antenna system 3 can also receive the electromagnetic wave. The process of receiving the electromagnetic wave is the reverse of the above process.

[0027] Alternatively, the first cable 250 and the vehicle-mounted unit 5 can be electrically connected in a pluggable manner via a connector. This configuration allows the antenna assembly 6 and the vehicle-mounted unit 5 to be produced independently, which is advantageous in reducing the difficulty of production and improving production efficiency. In addition, the first cable 250 can be connected to the vehicle-mounted unit 5 only when the antenna system 3 needs to be mounted on the vehicle body 2 for use. This can avoid the problem of the connection between the first cable 250 and the vehicle-mounted unit 5 being destroyed by external factors during transportation or sales.

[0028] The antenna assembly 6 included in the antenna system 3 according to the above embodiment will be described in detail below with reference to the drawings.

[0029] Referring to FIG. 4, the present application further provides an antenna assembly 6. The antenna assembly 6 includes a sunroof 10 and a combination antenna 20. The sunroof 10 is a glass attached to the top of the vehicle 1, and the shape of the sunroof 10 may be, but is not limited to, a square, a rectangle, a triangle, an oval, a circle, etc. The combination antenna 20 is placed on the sunroof 10 and provided at an end of the sunroof 10. The end refers to a position close to the edge of the sunroof 10, and the sunroof 10 has multiple ends, and the combination antenna 20 can be installed at any end. For example, a rectangular sunroof has four ends, and the combination antenna 20 can be installed at any of the four ends.

[0030] For ease of explanation, coordinate axes are introduced taking into account the perspective from which the antenna assembly 6 is shown in Figure 4, and the X-axis direction is defined as the width direction of the sunroof 10, the Y-axis direction is defined as the length direction of the sunroof 10, which is also the length direction (or driving direction) of the vehicle 1, and the direction perpendicular to the XOY plane is defined as the Z-axis direction, which is the thickness direction of the sunroof 10 and also the direction in which light is emitted.

[0031] The combination antenna 20 includes multiple antenna elements 200 operating in different frequency ranges. Multiple means that the number is two or more, and may be specifically two, three, five, six, etc. The antenna elements 200 may be, but are not limited to, frequency modulation (FM) / amplitude modulation (AM) antennas, TV antennas, phone antennas, navigation antennas, Bluetooth® antennas, 5G antennas, vehicle to everything (V2X) antennas, etc. In this application, the navigation antennas, 5G antennas, and V2X antennas are described as examples.

[0032] The multiple antenna elements 200 are arranged along the edge direction of the sunroof 10, that is, the multiple antenna elements 200 are arranged sequentially in the X-axis direction of FIG. 4. Of course, in other embodiments, the multiple antenna elements 200 can also be arranged sequentially along the Y-axis direction of FIG. 4. The edge direction of the sunroof 10 is related to the shape of the sunroof 10 itself, and the arrangement direction of the multiple antenna elements 200 can be changed accordingly. For example, if the shape of the sunroof 10 is circular, the edge direction of the sunroof 10 is arc-shaped, and the arrangement direction of the multiple antenna elements 200 can be set accordingly to be arc-shaped. If the shape of the sunroof 10 is rectangular (as shown in FIG. 4), the edge direction of the sunroof 10 is straight, and the arrangement direction of the multiple antenna elements 200 can be set accordingly to be straight.

[0033] On the other hand, by providing the combination antenna 20 on the sunroof 10, it is possible to avoid affecting the external design of the vehicle 1, and there is no need to worry about the problem of increased air resistance. In addition, by providing the combination antenna 20 on the edge of the sunroof 10, it is possible to avoid or reduce the combination antenna 20 blocking light rays, thereby ensuring that sufficient light rays are irradiated into the inside of the vehicle 1 through the sunroof 10, and a good daylighting effect is obtained. Furthermore, by arranging the multiple antenna elements 200 along the direction of the edge of the sunroof 10, the length direction of the vehicle-mounted unit 5 can be designed to be parallel to the arrangement direction of the multiple antenna elements 200. This setting increases the connection area between the vehicle-mounted unit 5 and the vehicle body 2, improves the stability of the connection, and makes it easy to arrange the first cable 250 between the vehicle-mounted unit 5 and the multiple antenna elements 200.

[0034] Referring to FIG. 4, the plurality of antenna elements 200 includes a radiator 240, a ground layer 260, and a first cable 250. The radiator 240 is configured to receive and transmit electromagnetic waves. The radiator 240 can be formed on the sunroof 10 by, for example, but not limited to, a silver paste printing or coating process. The radiator 240 includes a first radiator 211, a second radiator 221, and a third radiator 231, and these three radiators 240 belong to different antenna elements 200, which will be described in the following embodiments. The ground layer 260 is configured to provide a reference ground plane for the radiator 240. The ground layer 260 can be formed on the sunroof 10 by, for example, but not limited to, a silver paste printing process. The first cable 250 is configured to electrically connect the vehicle-mounted unit 5 and the radiator 240. Referring to FIG. 5, the first cable 250 includes an insulating sleeve 251 and a core wire 252. The core wire 252 is wrapped inside an insulating sleeve 251. The insulating sleeve 251 is connected to the ground layer 260, and the core wire 252 is configured to feed power to the radiator 240.

[0035] Referring to FIG. 4, the combination antenna 20 further includes a fixing part 270. The first cable 250 is fixed to one side of the sunroof 10 through the fixing part 270. It is understood that when the vehicle 1 is running, vibration is unavoidable, and the vibration may cause the first cable 250 to shake, and the first cable 250 may come off the sunroof 10 after shaking several times. In this embodiment, since the fixing part 270 is installed, the first cable 250 is fixed to the sunroof 10 through the fixing part 270, so that the first cable 250 between the fixing part 270 and the radiator 240 can be prevented from shaking significantly, and thus the above problem can be solved.

[0036] Referring to FIG. 4, the number of the first cables 250 is multiple, and the multiple first cables 250 are arranged at intervals along the direction of the edge of the sunroof 10. That is, the multiple first cables 250 are arranged in a dispersed manner. If the multiple first cables 250 are bundled together to form a single entire cable, the inertia of the entire cable is greater than the inertia of a single first cable 250, so that in the process of the entire cable swinging, the single first cable 250 in the entire cable is subjected to a greater tensile force, and in the long term, the connection of the first cable 250 may be torn off. Compared to bundling the multiple first cables 250, the multiple first cables 250 are distributed in this embodiment, which avoids large inertial forces and overcomes the above problem.

[0037] Referring to FIG. 6, the sunroof 10 includes an inner layer 110, an intermediate layer 120, and an outer layer 130, which are laminated in sequence. The inner layer 110 is a layer that the sunroof 10 is exposed to the inside of the vehicle 1, and the material thereof may be, but is not limited to, glass. The intermediate layer 120 is a layer sandwiched between the inner layer 110 and the outer layer 130, and is configured to bond the inner layer 110 and the outer layer 130. The material thereof may be, but is not limited to, polyvinyl butyral (PVB). The outer layer 130 is a layer that the sunroof 10 is exposed to the outside of the vehicle 1, and the material thereof may be, but is not limited to, glass.

[0038] 7 and 8, in one embodiment, the first cable 250 is configured to electromagnetically couple to the radiator 240 to feed power. Specifically, the radiator 240 is provided between the inner layer 110 and the outer layer 130, and the first cable 250 and the ground layer 260 are provided on the inner layer 110 on the side away from the radiator 240. A gap C1 is defined in the ground layer 260. The orthogonal projection of the first cable 250 on the ground layer 260 is at least partially within the range of the gap C1, that is, the orthogonal projection of the first cable 250 on the ground layer 260 intersects with the gap C1, so that the first cable 250 can electromagnetically couple to the radiator 240 to feed power through the gap C1 in the ground layer 260. The shape of the gap C1 may be, but is not limited to, a square, a rectangle, a circle, etc. In this application, no limitation is placed on the shape and size of the gap C1. It can be appreciated that electromagnetic coupling feed can increase the bandwidth of the antenna element 200, ie, the frequency range over which the antenna element 200 can operate effectively.

[0039] In addition, the radiator 240 may be provided between the inner layer 110 and the intermediate layer 120. For example, the radiator 240 may be formed on the surface of the inner layer 110 close to the outer layer 130 by a silver paste printing or coating process. The radiator 240 may also be provided between the outer layer 130 and the intermediate layer 120. In the embodiment of the present application, the radiator 240 is provided between the inner layer 110 and the intermediate layer 120. The embodiment of the present application will be described by way of example only on the basis that the radiator 240 is provided between the inner layer 110 and the intermediate layer 120. By providing the radiator 240 between the inner layer 110 and the outer layer 130, on the one hand, the conformalization of the antenna can be realized without affecting the structure of the sunroof 10, and on the other hand, the radiator 240 can be ensured to be protected from external interference or destruction, which is advantageous for the combination antenna 20 to stably perform the corresponding function.

[0040] Referring to FIG. 9, in another embodiment, the radiator 240 and the ground layer 260 are provided on the same side of the sunroof 10, and the first cable 250 is directly connected to the radiator 240 to feed power. For illustrative purposes, the radiator 240 and the ground layer 260 are both provided on a surface of the inner layer 110 that is separated from the outer layer 130. A gap C1 is defined in the ground layer 260, the radiator 240 is provided in the gap C1, and the first cable 250 can be connected to the radiator 240 by welding (not limited thereto), and this structure may be called a coplanar waveguide structure. By providing the radiator 240 and the ground layer 260 on a surface of the inner layer 110 that is separated from the outer layer 130, the problem that the above-mentioned electromagnetic coupling feed method (coupled feed) requires processing on both sides of the inner layer 110 that are separated from each other can be avoided, and processing efficiency can be improved. At the same time, the problem of the radiator 240 being damaged due to being pulled or pressed by the intermediate layer 120 can be avoided.

[0041] 10, the plurality of antenna elements 200 includes a first antenna element 210, a second antenna element 220, and a third antenna element 230. Each unit will be described in detail below with reference to the drawings.

[0042] The first antenna element 210 is a navigation antenna element. The navigation antenna element can receive position information to determine the current position of the vehicle 1. The first antenna element 210 includes a first radiator 211 and a first cable 250. The in-vehicle unit 5 is electrically connected to the first radiator 211 via the first cable 250, and the first cable 250 is configured to electromagnetically couple to the first radiator 211 to supply power or directly connect to the first radiator 211 to supply power (see the above-mentioned embodiment for details).

[0043] Alternatively, the geometric center of the first radiator 211 is located on the central axis of the sunroof 10. The sunroof 10 is also usually located on the central axis of the vehicle 1, i.e., the geometric center of the first radiator 211 is located on or approximately on the central axis of the vehicle 1. Since the first antenna element 210 is a navigation antenna element, the position information of the vehicle 1 is based on the position of the first antenna element 210. By arranging the first radiator 211 on the central axis of the sunroof 10, the position measurement of the vehicle 1 can be made more accurate. From the opposite perspective, if the first antenna element 210 is not provided on the central axis of the vehicle 1, the two position measurement points of the vehicle 1 before and after the direction of the front and rear ends of the vehicle 1 are changed at the same location are located on both sides of the central axis of the vehicle 1, i.e., there is a deviation between the position measurement results of the vehicle 1 heading in different directions at the same location.

[0044] Referring to FIG. 10, the multiple antenna elements 200 also include a second antenna element 220 provided on one side of the first antenna element 210. The second antenna element 220 includes multiple second radiators 221 and multiple first cables 250. Multiple means that the number is two or more, and the number of the second radiators 221 and the first cables 250 is equal. In this application, two will be described as examples only. The vehicle-mounted unit 5 is electrically connected to the second radiator 221 via the first cable 250, and the first cable 250 is configured to electromagnetically couple to the second radiator 221 to feed power or directly connect to the second radiator 221 to feed power (see the above-mentioned embodiment for details).

[0045] Furthermore, the multiple second radiators 221 and the multiple first cables 250 are all arranged along the edge direction of the sunroof 10, and different first cables 250 are connected to different second radiators 221. In other words, the multiple second radiators 221 are arranged along the edge direction of the sunroof 10, and the multiple first cables 250 are also arranged along the edge direction of the sunroof 10, and the first cables 250 and the second radiators 221 are connected one-to-one.

[0046] Furthermore, the second antenna element 220 may be, but is not limited to, a V2X antenna element. V2X is an abbreviation of vehicle to everything. V2X may include, but is not limited to, four aspects: V2N, V2V, V2I, and V2P. Vehicle-to-network (V2N) is the Internet of cars, and through V2N, the vehicle 1 can connect with a cloud server through a mobile network, and thus can realize application functions such as navigation, entertainment, and anti-theft. Through vehicle-to-vehicle (V2V), information exchange between vehicles 1 can be realized. Through vehicle-to-infrastructure (V2I), the vehicle 1 can exchange data with the road and road-side infrastructure, for example, to obtain information on traffic signals and various road signs. Its main function is to ensure the safety of pedestrians and light vehicles through vehicle-to-pedestrian (V2P) communication.

[0047] Referring to FIG. 10, the multiple antenna elements 200 also include a third antenna element 230 provided on the side of the navigation antenna element that is away from the second antenna element 220. The third antenna element 230 includes multiple third radiators 231 and multiple first cables 250. Multiple means that the number is two or more, and the third radiators 231 and the first cables 250 are equal in number. In this application, four will be described as an example only. Optionally, the third antenna element 230 is a 5G antenna element. The vehicle-mounted unit 5 is electrically connected to the third radiator 231 via the first cable 250, and the first cable 250 is configured to electromagnetically couple to the third radiator 231 to feed power or directly connect to the third radiator 231 to feed power (see the above-mentioned embodiment for details).

[0048] Furthermore, the multiple third radiators 231 and the multiple first cables 250 are all arranged along the direction of the edge of the sunroof 10, and different first cables 250 are connected to different third radiators 231. In other words, the multiple third radiators 231 are arranged along the direction of the edge of the sunroof 10, the multiple first cables 250 are arranged along the direction of the edge of the sunroof 10, and the first cables 250 and the third radiators 231 are connected one-to-one.

[0049] The sunroof 10 may be light-transmitting, semi-transmitting, or non-light-transmitting. The light transmittance of the sunroof 10 may be a constant value or a variable value (for example, electrochromism glass, photochromic glass, etc.).

[0050] 11, optionally, the sunroof 10 has a first area A1 and a second area A2 connected to each other. The first area A1 is a light-transmitting area, i.e., light can enter the interior of the vehicle 1 through the first area A1. The second area A2 is connected to the first area A1 so as to surround the first area A1 on all sides, and the second area A2 is a black edge area, which is not light-transmitting or has a poor light-transmitting effect compared with the first area A1. Furthermore, optionally, the combination antenna 20 is at least partially disposed in the second area A2, so that the combination antenna 20 can be hidden in the black edge area, thus making the sunroof 10 more beautiful and not hindering light from entering the interior of the vehicle 1.

[0051] Although the embodiments of the present application have been shown and described above, the above embodiments are illustrative and should not be understood as limiting the present application. Those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present application. These improvements and embellishments should also fall within the protection scope of the present application. [Explanation of symbols]
