Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of communication, and specifically relate to a vehicle. BACKGROUND

[0002] A vehicle is usually provided with a communication component, which can be a telematics box (Tbox) for example. The telematics box can be connected with a vehicle host to enable the vehicle host to realize communication with user terminals, satellites, communication base stations and other devices through the telematics box. In some weak field environments or specific signal coming wave environments, the communication component has a defect of antenna gain in a radiation pattern, and the communication performance of the whole vehicle is poor. SUMMARY

[0003] Embodiments of the present application provide a vehicle for improving the phenomenon of a defect of antenna gain in a radiation pattern.

[0004] In a first aspect, embodiments of the present application provide a vehicle, which includes a vehicle body, a first feed radiation body and a communication component. The vehicle body includes a frame and a chassis connected with each other. The first feed radiation body is mounted on the frame. The communication component is mounted on the frame or in a space enclosed by the frame and the chassis, and the communication component includes a plurality of feed radiation bodies, a switching module and a communication module. The working frequency bands of the plurality of feed radiation bodies are at least partially the same. The number of the plurality of feed radiation bodies is greater than the number of the first feed radiation body. At least one of the plurality of feed radiation bodies is a second feed radiation body. The working frequency bands of the second feed radiation body and the first feed radiation body are the same. The distance between the second feed radiation body and at least one of the first feed radiation bodies is greater than 40 cm. The common port of the switching module is coupled with the communication module. The first port of the switching module is coupled with the second feed radiation body. The second port of the switching module is coupled with the first feed radiation body through a cable.

[0005] The communication assembly can be installed in a space surrounded by the frame and the chassis, and the space surrounded by the frame and the chassis can be used for driving, riding and storage (for example, the communication assembly can be installed in a trunk surrounded by a rear cover of the frame), or the communication assembly can be installed in an interior of the frame (for example, the frame can include a spoiler, the spoiler can be a hollow structure, and the communication assembly can be located in an interior of the spoiler of the frame). The first feeding radiator can be installed on the frame. It can be understood that the first feeding radiator can be installed in an interior of an insulating part in the frame, or the first feeding radiator can be installed on an outer surface of the frame, or the first feeding radiator can be installed on an inner surface of the frame. Through the above arrangement, when the vehicle communicates, the plurality of feeding radiators of the communication assembly can be used as the main part, and the first feeding radiator can be used as the auxiliary part. When the second feeding radiator is blocked by the vehicle body and has an antenna gain defect, the first feeding radiator can compensate for the antenna gain defect, which is beneficial to avoid the antenna gain defect caused by the blocking of the vehicle body and improve the communication performance of the whole vehicle.

[0006] In some embodiments that can include the above-mentioned embodiments, the communication module includes a control unit, and the communication module has an initial working state and a first working state. The control unit is configured to control the switching module to couple the communication module and the second feeding radiator in the initial working state. The control unit is further configured to control the switching module to couple the communication module and the first feeding radiator in the first working state. Through the above arrangement, when the vehicle communicates, the second feeding radiator is mainly used for communication, and the first feeding radiator is used as an auxiliary part to compensate for the gain defect of the second feeding radiator, thereby improving the communication performance of the whole vehicle.

[0007] In some embodiments that can include the above-mentioned embodiments, the communication module further includes a detection unit configured to obtain a signal strength of the first feeding radiator and a signal strength of the second feeding radiator. The communication module is configured to switch from the initial working state to the first working state when the signal strength of the second feeding radiator is less than a preset value and the signal strength of the second feeding radiator is less than the signal strength of the first feeding radiator. Through the above arrangement, since the signal strength of the first feeding radiator is stronger than the signal strength of the second feeding radiator, the communication assembly communicates through the first feeding radiator in the first working state, which is beneficial to improve the communication performance of the whole vehicle.

[0008] In some embodiments that may include the above embodiments, the communication module further includes a detection unit configured to obtain relative position information between the satellite and the vehicle body. The relative position information indicates the position and attitude of the vehicle body relative to the satellite in a plane parallel to the bottom surface of the vehicle. The communication module is configured to switch from an initial operating state to a first operating state based on the relative position information. With this configuration, in the first operating state, the communication component communicates via the first feed radiator, thereby improving the communication performance of the entire vehicle.

[0009] In some embodiments that may include the above embodiments, the first feed radiator and the second feed radiator together form an omnidirectional antenna. Through the above arrangement, the first feed radiator and the second feed radiator can together form an omnidirectional coverage effect, thereby improving the communication performance of the entire vehicle.

[0010] In some embodiments that may include the above embodiments, some of the multiple feed radiators form a main antenna, some of the multiple feed radiators form at least one diversity antenna, and the first feed radiator and the main antenna are coupled to the communication module via a switching module. With this arrangement, when the communication module is coupled to the main antenna, the communication module can receive and transmit signals via the main antenna; and when the communication module is coupled to the first feed radiator, the communication module can receive and transmit signals via the first feed radiator.

[0011] In some embodiments that may include the above embodiments, within a plane parallel to the bottom surface of the vehicle, the first feed radiator is used as an antenna to transmit and receive signals within a first coverage area, and the second feed radiator is used as an antenna to transmit and receive signals within a second coverage area. The coverage angle of the first coverage area is smaller than the coverage angle of the second coverage area. Because the coverage angle of the first coverage area is smaller than the coverage angle of the second coverage area, when the vehicle communicates, the second feed radiator is used primarily for communication, while the first feed radiator is used as a supplement to compensate for the gain deficiency caused by the second feed radiator, thereby improving the communication performance of the entire vehicle.

[0012] In some embodiments that may include the above-mentioned embodiments, the frame includes a front cover, a front windshield, a top structure, a rear windshield, and a rear cover, arranged sequentially from the front to the rear of the vehicle. The communication component is located within the top structure, and the first feed radiator is disposed on the front windshield or the rear windshield. By distributing the first and second feed radiators, if the second feed radiator has an antenna gain deficiency, the first feed radiator can compensate for the deficiency, thereby avoiding antenna gain deficiencies caused by vehicle obstruction and improving the overall vehicle communication performance.

[0013] In some embodiments which can include the above-mentioned embodiments, the frame comprises, in sequence from the vehicle head to the vehicle tail of the vehicle body, a front cover, a front windshield, a top structural member, a rear windshield, and a rear cover. The communication component is located at one side of the rear cover, and the first feeding radiator is arranged on the front windshield or the top structural member. Through the distributed arrangement of the first feeding radiator and the second feeding radiator, when the second feeding radiator has antenna gain defects, the first feeding radiator located can compensate for the antenna gain defects, which is conducive to avoiding antenna gain defects caused by the vehicle body shielding and improving the communication performance of the whole vehicle.

[0014] In some embodiments which can include the above-mentioned embodiments, the communication component comprises a vehicle networking terminal box. Through the arrangement of the first feeding radiator and the second feeding radiator, when the second feeding radiator has antenna gain defects, the first feeding radiator located can compensate for the antenna gain defects, which can improve the communication performance of the vehicle networking terminal box.

[0015] In the second aspect, the embodiments of the present application provide a vehicle, which comprises a vehicle body, a communication component, a first feeding radiator and a second feeding radiator. The vehicle body comprises a frame and a chassis connected to each other. The communication component is installed in a space enclosed by the frame and the chassis. The first feeding radiator and the second feeding radiator are installed on the frame, the distance between the first feeding radiator and the second feeding radiator is greater than 40 cm, the first feeding radiator and the second feeding radiator are both coupled to the communication component, the working frequency bands of the second feeding radiator and the first feeding radiator are the same, and the first feeding radiator and the second feeding radiator jointly constitute an omnidirectional antenna.

[0016] Through the above arrangement, the first feeding radiator and the second feeding radiator are installed on the frame, which is conducive to avoiding the vehicle body shielding the first feeding radiator and the second feeding radiator. When one feeding radiator has antenna gain defects, the other feeding radiator can compensate for the antenna gain defects, so that the first feeding radiator and the second feeding radiator jointly form an omnidirectional coverage effect, thereby improving the communication performance of the whole vehicle.

[0017] In some embodiments which can include the above-mentioned embodiments, in a plane parallel to the chassis of the vehicle, the first feeding radiator is used as an antenna and transmits and receives signals in a first coverage area, the second feeding radiator is used as an antenna and transmits and receives signals in a second coverage area, and the coverage angle of at least part of the first coverage area and the coverage angle of at least part of the second coverage area are supplementary angles. Since the coverage angle of at least part of the first coverage area and the coverage angle of at least part of the second coverage area are supplementary angles, the first feeding radiator and the second feeding radiator jointly form an omnidirectional coverage effect, thereby improving the communication performance of the whole vehicle.

[0018] In some embodiments which can comprise the above-mentioned embodiments, the distance between the first feeding radiator and the second feeding radiator is greater than or equal to 1 meter. By the above-mentioned arrangement, the antenna gain defect caused by the shielding of the vehicle body is further avoided, so that the first feeding radiator and the second feeding radiator jointly form the effect of omnidirectional coverage, and the communication performance of the whole vehicle is further improved.

[0019] In some embodiments which can comprise the above-mentioned embodiments, the frame comprises a top portion, a first side portion and a second side portion, the top portion extends from the front of the vehicle body to the rear of the vehicle body, the first side portion and the second side portion are arranged along a first direction, the top portion is located between the first side portion and the second side portion, the first direction is parallel to the chassis of the vehicle and perpendicular to the direction from the front of the vehicle body to the rear of the vehicle body. The first feeding radiator is arranged on the top portion, and the second feeding radiator is arranged on the top portion. By arranging the first feeding radiator and the second feeding radiator on the top portion of the vehicle body, one of the two feeding radiators can be used to transmit and receive signals in the front direction of the vehicle, and the other of the two feeding radiators can be used to transmit and receive signals in the rear direction of the vehicle, so that the first feeding radiator and the second feeding radiator jointly form the effect of omnidirectional coverage, and the communication performance of the whole vehicle is improved.

The second feeding radiator arranged on the top portion comprises: the second feeding radiator is arranged on one of the front windshield, the top structural member, the rear windshield and the rear cover. Since the first feeding radiator and the second feeding radiator are not arranged on the front cover of the vehicle body, it is beneficial to avoid the influence of the first feeding radiator and the second feeding radiator on the appearance of the whole vehicle, and to avoid the influence on the wind resistance of the whole vehicle.

[0021] In some embodiments which can comprise the above-mentioned embodiments, the frame comprises a top portion, a first side portion and a second side portion, the top portion extends from the front of the vehicle body to the rear of the vehicle body, the first side portion and the second side portion are arranged along a first direction, the top portion is located between the first side portion and the second side portion, the first direction is parallel to the chassis of the vehicle and perpendicular to the direction from the front of the vehicle body to the rear of the vehicle body.

The first feed radiator is disposed on the first side portion, including: the first feed radiator is disposed on one of the first rearview mirror and the first triangular window. The second feed radiator is disposed on the second side portion, including: the second feed radiator is disposed on one of the second rearview mirror and the second triangular window. Through the above-mentioned arrangement, one of the two feed radiators can be primarily used to transmit and receive signals in the left direction of the vehicle, and the other of the two feed radiators can be primarily used to transmit and receive signals in the right direction of the vehicle, so that the first feed radiator and the second feed radiator together form an omnidirectional coverage effect, thereby improving the communication performance of the entire vehicle.

[0043] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0044] Hereinafter, the terms "first", "second", and the like are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implying the number of the technical features indicated. Therefore, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features.

[0045] In addition, in the embodiments of the present application, the orientation terms such as "upper", "lower", "left", "right", "horizontal" and "vertical" are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0046] In the embodiments of the present application, unless otherwise explicitly specified and limited, the term "connection / connected" should be understood in a broad sense, which can refer to a mechanical connection relationship or a physical connection relationship, that is, A and B are connected or A and B are connected, which means that there is a fastening component (such as a screw, a bolt, a rivet, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to be separated.

[0047] Communication connection: can refer to electrical signal transmission, such as wireless communication connection and / or wired communication connection. Wireless communication connection does not require physical medium, and does not belong to the connection relationship limiting the product structure.

[0048] Coupling: can be understood as direct coupling and / or indirect coupling, and "coupling connection" can be understood as direct coupling connection and / or indirect coupling connection. Direct coupling can also be referred to as "electrical connection", which is understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in the circuit structure through the physical circuit of copper foil or wire of printed circuit board (PCB) which can transmit electrical signals; "indirect coupling" can be understood as electrical conduction between two conductors in a spaced / untouched manner. In an embodiment, indirect coupling can also be referred to as capacitive coupling, for example, through the coupling between the gap between two conductive parts to form an equivalent capacitor to realize signal transmission.

[0049] On: through the above "electrical connection" or "indirect coupling" to make two or more components conductive or connected to transmit signals / energy, which can be referred to as on.

[0050] Radiating element, or antenna element: a device in an antenna for receiving / transmitting electromagnetic wave radiation. In some cases, "antenna" is understood in a narrow sense as a radiating element, which converts guided wave energy from a transmitter into radio waves, or converts radio waves into guided wave energy for radiation and reception of radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted via a feed line to the transmitting radiating element, which converts it into some polarized electromagnetic wave energy and radiates it in the desired direction. The receiving radiating element converts the electromagnetic wave energy of some polarization from a certain direction in space into modulated high-frequency current energy, which is delivered to the input of the receiver via a feed line.

[0051] The radiating element (or antenna element) can include a conductor with a certain shape and size, such as a wire, or a patch, etc., which is not limited in this application. In an embodiment, the wire radiating element can be referred to as a wire antenna. In an embodiment, the wire radiating element can be implemented by a conductive frame, which can also be referred to as a frame antenna. In an embodiment, the wire radiating element can be implemented by a bracket conductor, which can also be referred to as a bracket antenna. In an embodiment, the wire radiating element, or the wire diameter (e.g., including thickness and width) of the radiating element of the wire antenna is much smaller (e.g., less than 1 / 16 of the wavelength) than the wavelength (e.g., the medium wavelength), and the length can be comparable to the wavelength (e.g., the length is around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of wire antennas include dipole antennas, half-wave dipole antennas, monopole antennas, loop antennas, inverted F antennas (also referred to as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna generally includes two radiating elements, each of which is fed by a feed from the feed end of the radiating element. For example, the inverted F antenna (Inverted-F Antenna, IFA) can be regarded as an inverted F antenna obtained by adding a ground path to a monopole antenna. The IFA antenna has a feed point and a ground point, and is called an inverted F antenna because its side view is in the shape of an inverted F. In an embodiment, the patch radiating element can include a microstrip antenna, or a patch antenna, such as a planar inverted F antenna (also referred to as PIFA, Planar Inverted F Antenna). In an embodiment, the patch radiating element can be implemented by a planar conductor (e.g., a conductive patch or a conductive coating, etc.). In an embodiment, the patch radiating element can include a conductive patch, such as a copper patch, etc. In an embodiment, the patch radiating element can include a conductive coating, such as silver paste, etc. The shape of the patch radiating element includes a circle, a rectangle, a ring, etc., which is not limited in this application. The structure of the microstrip antenna is generally composed of a dielectric substrate, a radiating element, and a ground plate, wherein the dielectric substrate is arranged between the radiating element and the ground plate.

[0052] The radiators (or antenna elements) can also include slots or gaps formed on the conductors, e.g., forming a closed or semi-closed slot or gap on a grounded conductor plane. In one embodiment, the slotted or gapped radiators can be referred to as slot antennas or gap antennas. In one embodiment, the slot or gap of a slot antenna / gap antenna has a radial dimension (e.g., including width) much smaller than a wavelength (e.g., a dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and a length dimension comparable to a wavelength (e.g., dielectric wavelength) (e.g., around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, the radiators with closed slots or gaps can be referred to as closed slot antennas. In one embodiment, the radiators with semi-closed slots or gaps (e.g., with openings added to the closed slots or gaps) can be referred to as open slot antennas. In some embodiments, the gap shape is long and thin. In some embodiments, the gap length is about half a wavelength (e.g., dielectric wavelength). In some embodiments, the gap length is about an integer number of wavelengths (e.g., one dielectric wavelength). In some embodiments, the gap can be fed by a transmission line that is connected across one or both sides of the gap, whereby the gap is excited with a radio frequency electromagnetic field and radiates electromagnetic waves into space. In one embodiment, the radiators of a slot antenna or gap antenna can be implemented by a conductive frame that is grounded at both ends, which can also be referred to as a frame antenna; in this embodiment, the slot antenna or gap antenna can be considered to include a linear radiator that is spaced apart from the ground plane and grounded at both ends, thereby forming a closed or semi-closed slot or gap. In one embodiment, the radiators of a slot antenna or gap antenna can be implemented by a bracket conductor that is grounded at both ends, which can also be referred to as a bracket antenna.

[0053] Communication band / operating band: Regardless of the type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna that supports the B40 band has an operating band that includes frequencies in the range of 2300-2400 MHz, or in other words, the operating band of the antenna includes the B40 band. The frequency range that meets the index requirements can be considered the operating band of the antenna. The width of the operating band is referred to as the operating bandwidth. The operating bandwidth of an omnidirectional antenna can be 3-5% of the center frequency. The operating bandwidth of a directional antenna can be 5-10% of the center frequency. The bandwidth can be considered a range of frequencies on both sides of the center frequency (e.g., the resonant frequency of a dipole), where the antenna characteristics are within an acceptable range of values at the center frequency.

[0054] The resonant frequency band and the operating frequency band can be the same, or can partially overlap. In one embodiment, one or more resonant frequency bands of an antenna can cover one or more operating frequency bands of the antenna.

[0055] End / point: the "end / point" in the first end / second end / feed end / ground end / feed point / ground point / connection point of the antenna radiator, which cannot be understood as an end point or end that is physically disconnected from other radiators in a narrow sense, but can also be considered as a certain point or a certain section on a continuous radiator. In an embodiment, the "end / point" can include a connection / coupling area on the antenna radiator that is coupled to other conductive structures, for example, the feed end / feed point can be a coupling area (for example, an area facing a part of the feed circuit) on the antenna radiator that is coupled to a feed structure or a feed circuit, and for another example, the ground end / ground point can be a connection / coupling area on the antenna radiator that is coupled to a ground structure or a ground circuit.

[0056] The definitions such as collinear, coaxial, coplanar, symmetric (for example, axisymmetric or centrosymmetric), parallel, perpendicular, identical (for example, the same length, the same width, and the like), and the like mentioned in the embodiments of the present application are for the current process level, not the absolute strict definition in the mathematical sense. There can be a deviation less than a predetermined threshold (for example, 1 mm, 0.5 m, or 0.1 mm) in the line width direction between the edges of two radiating branches or two antenna units that are collinear. There can be a deviation less than a predetermined threshold in the direction perpendicular to the coplanar plane between the edges of two radiating branches or two antenna units that are coplanar. There can be a deviation of a predetermined angle between two antenna units that are parallel or perpendicular to each other. In an embodiment, the predetermined threshold can be less than or equal to a threshold of 1 mm, for example, the predetermined threshold can be 0.5 mm, or can be 0.1 mm. In an embodiment, the predetermined angle can be an angle within a range of ±10°, for example, the predetermined angle deviation is ±5°.

[0057] The same operating frequency band (also referred to as the same frequency) mentioned in the embodiments of the present application can be understood as any one of the following two cases:

[0058] 1) The operating frequency band of the first antenna and the operating frequency band of the second antenna include the same communication frequency band. In an embodiment, the first antenna and the second antenna both serve as subunits in a MIMO antenna system. For example, the operating frequency band of the first antenna and the operating frequency band of the second antenna both include the sub6G frequency band in 5G.

[0059] 2) The operating frequency band of the first antenna and the operating frequency band of the second antenna partially overlap in frequency. For example, the operating frequency band of the first antenna includes B35 (1.85-1.91 GHz) in LTE, and the operating frequency band of the second antenna includes B39 (1.88-1.92 GHz) in LTE.

[0060] Antenna pattern: Also known as radiation pattern. It is a graph showing how the relative field strength (normalized modulus) of the antenna's radiation field changes with direction at a certain distance from the antenna. It is usually represented by two mutually perpendicular plane patterns passing through the antenna's direction of maximum radiation.

[0061] Antenna patterns typically have multiple radiation beams. The beam with the strongest radiation intensity is called the main lobe, while the remaining beams are called side lobes. Among the side lobes, those in the opposite direction of the main lobe are also called back lobes.

[0062] Antenna Gain: This is used to measure how well an antenna radiates input power. Generally, the narrower the main lobe of an antenna pattern and the smaller the side lobes, the higher the antenna gain.

[0063] Reference Figure 1 and Figure 2 The embodiment of the present application provides a vehicle, which includes a communication component 10 and a vehicle body 20. The vehicle body 20 includes a frame 201 and a chassis 202 connected to each other. The chassis 202 can be used to support and install the frame 201 to form the overall shape of the vehicle.

[0064] The communication component 10 is installed in the space enclosed by the frame 201 and the chassis 202 (such as Figure 1 The space can be used for driving, riding and storage (such as Figure 1 As shown, the communication component 10 can be located in a trunk enclosed by the rear cover of the vehicle body 20). Alternatively, the communication component 10 can also be installed on the frame 201 (for example, the frame 201 can include a spoiler, the spoiler can be a hollow structure, and the communication component can be located inside the spoiler of the frame 201).

[0065] However, because the vehicle body 20 is made of metal, in some weak field environments or environments with specific signal waves, the vehicle body 20 has a certain shielding effect on the antenna of the communication component 10, resulting in gain defects in the antenna of the communication component 10 at certain angles in the directional pattern. The directional pattern of the entire vehicle has antenna gain defects, and the communication performance of the entire vehicle is poor. For example, the vehicle's OTA (Over-the-Air Technology) performance is poor, or the network signal strength inside the vehicle is weak.

[0066] In view of this, if Figure 2As shown, the vehicle in the embodiment of the present application can include a first feeding radiator 31. The first feeding radiator 31 is mounted on the frame 201. Wherein, the first feeding radiator 31 can be mounted on the frame 201, which can be understood as that the first feeding radiator 31 can be mounted inside the frame 201, or the first feeding radiator 31 can be mounted on the outer surface of the frame 201, or the first feeding radiator 31 can be mounted on the inner surface of the frame 201.

[0067] For example, when the first feeding radiator 31 is arranged on the metal part of the vehicle body 20, the first feeding radiator 31 can be mounted on the vehicle body 20 in a way of adsorption, plug-in, threaded connection, etc., so that the first feeding radiator 31 can be used as a shark fin antenna, a luggage rack antenna, etc. At this time, the first feeding radiator 31 can be mounted on the outer surface of the frame 201. When the first feeding radiator 31 is arranged on the glass of the frame 201, a metal plating film can be arranged on the surface of the glass substrate, so that the first feeding radiator 31 can be located on the outer surface or the inner surface of the frame 201; or a metal plating film can also be arranged between the two glass substrates, so that the first feeding radiator 31 can be arranged inside the frame 201. Further, when the first feeding radiator 31 is mounted inside the frame 201 or on the inner surface of the frame 201, the first feeding radiator 31 can be mounted on the insulating part of the frame 201, such as a plastic part or glass. Through the above arrangement, it is beneficial to avoid the metal part in the vehicle body 20 from shielding the first feeding radiator 31, so as to affect the performance of the first feeding radiator 31.

[0068] Of course, the first feeding radiator 31 can also be mounted on the vehicle body 20 in other ways, and the embodiment of the present application does not limit the mounting form of the first feeding radiator 31.

[0069] In the embodiment of the present application, the communication assembly 10 can include a plurality of feeding radiators 14. The working frequency bands of the plurality of feeding radiators 14 are at least partially the same. For example, the working frequency bands of a part of the plurality of feeding radiators 14 can be low, medium and high frequency, and the working frequency bands of another part of the plurality of feeding radiators 14 can be medium and high frequency. The number of the plurality of feeding radiators 14 is greater than the number of the first feeding radiator 31. Through the above arrangement, when the vehicle communicates, the plurality of feeding radiators 14 of the communication assembly 10 can be used as the main communication, and the first feeding radiator 31 can be used to compensate for the antenna gain defects of the plurality of feeding radiators 14.

[0070] The at least one of the plurality of feeding radiators 14 is a second feeding radiator 32, and the second feeding radiator 32 and the first feeding radiator 31 have the same working frequency band. For example, the first feeding radiator 31 can be coupled to the communication assembly 10, so that the second feeding radiator 32 and the first feeding radiator 31 can support the same communication function. The distance between the second feeding radiator 32 and the at least one first feeding radiator 31 is greater than 40 cm. Through the above arrangement, the first feeding radiator 31 and the second feeding radiator 32 have a certain distance, so that the first feeding radiator 31 and the second feeding radiator 32 can be relatively dispersedly distributed on the vehicle body 20, which is beneficial to the radiation uniformity of the antenna composed of the first feeding radiator 31 and the second feeding radiator 32 in the radiation pattern.

[0071] The communication assembly 10 further includes a switching module 12 and a communication module 11. The plurality of feeding radiators 14 can be connected to the communication module 11 through corresponding radio frequency channels 13. The common port 12a of the switching module 12 is coupled to the communication module 11, the first port 12b of the switching module 12 is coupled to the second feeding radiator 32, and the second port 12c of the switching module 12 is coupled to the first feeding radiator 31 through the cable 40. The common port 12a of the switching module 12 can be coupled to the communication module through the radio frequency channel 13, and the cable 40 can be connected to the first feeding radiator 31 through the corresponding connector 50 (for example, FAKRA connector).

[0072] In some embodiments, the switching module 12 can include a mechanical switching switch, for example, a single-pole three-throw switch, and the three switching terminals of the single-pole three-throw switch are respectively used to connect the communication module 11, the first feeding radiator 31 and the second feeding radiator 32. Alternatively, in some embodiments, the switching module 12 can also include an electronic switching switch, for example, three switching channels composed of switching tubes, and the three switching channels are respectively used to connect the communication module 11, the first feeding radiator 31 and the second feeding radiator 32.

[0073] Through the above arrangement, when the second feeding radiator 32 has an antenna gain defect, the first feeding radiator 31 can compensate for the antenna gain defect, which is beneficial to avoid the antenna gain defect caused by the shielding of the vehicle body 20, and improve the communication performance of the whole vehicle.

[0074] In some examples, the communication component 10 can include a telematics box. The telematics box can be connected with the vehicle host computer, so that the vehicle host computer can realize communication with user mobile terminals, satellites, vehicles, roadside devices, communication base stations and other devices through the telematics box. By setting the first feeding radiator 31 and the second feeding radiator 32, when the second feeding radiator 32 has antenna gain defects, the first feeding radiator 31 can compensate for the antenna gain defects, and the communication performance of the telematics box can be improved. For example, the phone can be improved from being unable to call out to successfully calling out to the phone, and the vehicle-mounted audio and video entertainment system can be changed from stuttering to smooth.

[0075] In some embodiments, the telematics box can include a cellular antenna to realize information interaction with the outside TSP (Telematics Service Platform) through the cellular base station. In some embodiments, the telematics box can also include a global satellite navigation system (GNSS) antenna, hereinafter referred to as a satellite antenna, to realize Beidou satellite navigation system (BDS) navigation or global positioning system (GPS) navigation, and the vehicle special microcomputer controller can realize the positioning and navigation functions of the vehicle through the telematics processor. Alternatively, in some embodiments, the telematics box can include a V2X (Vehicle-to-everything) antenna to realize communication with other things. Alternatively, in some embodiments, the telematics box can also include a geosynchronous orbit satellite system (GEO) to realize satellite voice and data communication.

[0076] In some embodiments, the first feed radiator 31 and the second feed radiator 32 can together form an omnidirectional antenna. Here, "omnidirectional antenna" can be understood as uniform radiation from 0° to 360° in the horizontal pattern, and at least partial radiation in the vertical pattern. For example, when the first feed radiator 31 and the second feed radiator 32 are both used as cellular antennas or V2X antennas, they exhibit uniform radiation from 70° to 90° in the vertical pattern; when the first feed radiator 31 and the second feed radiator 32 are both used as satellite 80 antennas, they exhibit uniform radiation from 0° to 80° in the vertical pattern. Through the above configuration, the first feed radiator 31 and the second feed radiator 32 can jointly form an omnidirectional coverage effect, thereby improving the communication performance of the entire vehicle.

[0077] In some embodiments, as Figure 2 and Figure 3 As shown, the communication module 11 can have an initial working state and a first working state. The communication module 11 may include a control unit 115. The control unit 115 may be configured to, in the initial working state, control the switching module 12 to couple the communication module 11 with the second feed radiator 32. The control unit 115 may also be configured to, in the first working state, control the switching module 12 to couple the communication module 11 with the first feed radiator 31. The control unit 115 of the communication module 11 may send a control signal to the switching module 12 to control the first port 12b and the second port 12c of the switching module 12 to connect or disconnect, thereby coupling the communication module 11 with the second feed radiator 32 or coupling the communication module 11 with the first feed radiator 31.

[0078] For example, during vehicle communication, in the initial operating state, the control unit 115 can control the first port 12b of the switching module 12 to be connected, and the control unit 115 can control the second port 12c of the switching module 12 to be disconnected, so that the communication module 11 is coupled to the second feeding radiator 32. In the first operating state, the control unit 115 can control the second port 12c of the switching module 12 to be connected, and the control unit 115 can control the first port 12b of the switching module 12 to be disconnected, so that the communication module 11 is coupled to the first feeding radiator 31. Through the above configuration, when the vehicle is communicating, the second feeding radiator 32 is the primary source of power, while the first feeding radiator 31 is used as a secondary source to compensate for the gain deficiency caused by the second feeding radiator 32, thereby improving the communication performance of the entire vehicle.

[0079] In some embodiments, the communication module 11 may further include a detection unit 113, which is further configured to obtain the signal strength of the first feeding radiator 31 and the signal strength of the second feeding radiator 32. The detection unit 113 may be coupled to the control unit 115, and the communication module 11 may obtain radio frequency signals from the first feeding radiator 31 and the second feeding radiator 32, so that the detection unit 113 obtains the signal strength of the first feeding radiator 31 and the signal strength of the second feeding radiator 32. The communication module 11 is configured to switch from the initial operating state to the first operating state when the signal strength of the second feeding radiator 32 is less than a preset value and the signal strength of the second feeding radiator 32 is less than the signal strength of the first feeding radiator 31.

[0080] Here, the "preset value" can be understood as the minimum value of the signal strength at which the second feed radiator 32 can ensure the stability of the communication connection. The signal strength can be represented by the parameter RSRP (Reference Signal Receiving Power). RSRP is the average value of the signal power received on all REs (resource elements) carrying the cell reference signal in the specified measurement frequency band. The larger the RSRP value, the stronger the effective signal received by the antenna.

[0081] In some examples, such as Figure 4 As shown, in a weak field environment or an environment without a network, such as an underground garage, a tunnel, a suburb, a highway in a remote area, etc. with a poor signal (for example, RSRP is less than -105dBm), the signal strength at the second feed radiator 32 is poor. Alternatively, in some other examples, when the incoming direction of the base station signal is blocked by the vehicle body 20, the signal strength at the second feed radiator 32 may also be poor. For example, Figure 5 As shown, when the second feeding radiator 32 is set in the trunk surrounded by the rear cover of the vehicle body 20, and the incoming direction of the base station signal points to the front of the vehicle, the signal strength of the second feeding radiator 32 is poor (such as Figure 5 The dotted line in the figure indicates that the vehicle forward incoming wave signal strength is poor. Of course, the poor signal strength of the second feeding radiator 32 is not limited to the above two cases, and the embodiment of the present application does not limit this.

[0082] In the initial operating state, the control unit 115 controls the switching module 12 to couple the communication module 11 with the second feed radiator 32, allowing the detection unit 113 to obtain the signal strength of the second feed radiator 32. When the signal strength received by the second feed radiator 32 is poor, the signal strength of the second feed radiator 32 obtained by the detection unit 113 is less than a preset value. The control unit 115 controls the switching module 12 to couple the communication module 11 with the first feed radiator 31, allowing the detection unit 113 to obtain the signal strength of the first feed radiator 31. When the signal strength of the second feed radiator 32 is less than the signal strength of the first feed radiator 31, the communication module 11 switches from the initial operating state to the first operating state, and the control unit 115 controls the switching module 12 to continue coupling the communication module 11 with the first feed radiator 31.

[0083] Through the above configuration, since the signal strength of the first feeding radiator 31 is stronger than the signal strength of the second feeding radiator 32 , in the first working state, the communication component 10 communicates through the first feeding radiator 31 , which is beneficial to improving the communication performance of the entire vehicle.

[0084] In some other examples, the communication module 11 further has a second working state, and the control unit 115 can be further configured to, in the second working state, control the switching module 12 to couple the communication module 11 with the second feeding radiator 32. The communication module 11 is further configured to switch from the first working state to the second working state when the signal strength of the second feeding radiator 32 is less than a preset value and the signal strength of the second feeding radiator 32 is greater than the signal strength of the first feeding radiator 31.

[0085] As described in the above embodiment, when the signal strength of the second feeding radiator 32 obtained by the detection unit 113 is less than a preset value, the control unit 115 controls the switching module 12 to couple the communication module 11 and the first feeding radiator 31, and the detection unit 113 can obtain the signal strength of the first feeding radiator 31. When the signal strength of the second feeding radiator 32 is greater than the signal strength of the first feeding radiator 31, the communication module 11 switches from the first operating state to the second operating state, and the control unit 115 controls the switching module 12 to couple the communication module 11 and the second feeding radiator 32.

[0086] In some other examples, such as Figure 6As shown, in the medium field environment (for example, the RSRP is greater than -105dBm), and the direction of arrival of the base station signal has multiple directions, the base station signal can not be blocked by the vehicle body 20. At this time, in the initial working state, the control unit 115 controls the switching module 12 to couple the communication module 11 and the second feeding radiator 32, and the detection unit 113 can obtain the signal strength of the second feeding radiator 32. Since the signal strength of the second feeding radiator 32 obtained by the communication module 11 is greater than or equal to the preset value, the control unit 115 controls the switching module 12 to continue to couple the communication module 11 and the second feeding radiator 32. Through the above setting, it is beneficial to exert the advantages of good OTA performance of the multiple feeding radiators 14 inside the communication assembly 10 and the MIMO (Multiple-input Multiple-output) advantage, and to guarantee the low latency and high efficiency of communication.

[0087] Based on the above embodiment, the first feeding radiator 31 and the second feeding radiator 32 can be used as cellular antennas, so that the first feeding radiator 31 and the second feeding radiator 32 can communicate with the base station. Alternatively, the first feeding radiator 31 and the second feeding radiator 32 can be used as satellite 80 antennas, so that the first feeding radiator 31 and the second feeding radiator 32 can communicate with the satellite 80.

[0088] In some examples, the communication module 11 further includes a detection unit 113, and the detection unit 113 is configured to obtain relative pose information between the satellite 80 and the vehicle body 20, the relative pose information being used to represent a position and an attitude of the vehicle body 20 relative to the satellite 80 in a plane parallel to the vehicle bottom surface.

[0089] As shown, the relative pose information includes a relative position and a relative attitude. Figure 3 As shown, the relative position includes a relative horizontal position and a relative vertical position. Figure 7 As shown, in the plane parallel to the vehicle bottom surface (for example, the relative horizontal position is greater than 0, and the relative vertical position is greater than 0), the first feeding radiator 31 and the second feeding radiator 32 can be used as cellular antennas, so that the first feeding radiator 31 and the second feeding radiator 32 can communicate with the base station. Figure 7The position and posture of the vehicle body 20 relative to the satellite 80 can be represented by the distance and the azimuth angle B (azimuth) of the vehicle body 20 relative to the satellite 80. For example, the detection unit 113 can include an IMU (Inertial Measurement Unit) sensor, and the communication module 11 can obtain the current latitude and longitude information of the vehicle and calculate the elevation angle A of the vehicle relative to the satellite 80 according to the latitude and longitude information. Here, the elevation angle A refers to the angle of rotation of the vehicle body 20 relative to the satellite 80 upward or downward from a reference plane (for example, a plane parallel to the bottom surface of the vehicle in the embodiment of the application), which can range from -90 to 90 degrees, for example. Further, the detection unit 113 can calculate the azimuth angle B of the vehicle relative to the satellite 80 according to the elevation angle A of the vehicle relative to the satellite 80. The azimuth angle B refers to the angle of rotation of the vehicle body 20 relative to the satellite 80 clockwise or counterclockwise from a reference direction (for example, a direction in which the tail of the vehicle body 20 points to the head in the embodiment of the application), which can range from 0 to 360 degrees, for example.

[0090] Based on the above settings, in combination with Figure 8 As shown in FIG. 1, in a plane parallel to the bottom surface of the vehicle, the first feed radiation body 31 can be used as an antenna and transceive signals in the first coverage area M1. In the embodiment of the application, the "bottom surface of the vehicle" can be understood as a plane on which the chassis 202 of the vehicle is located, or the "plane parallel to the bottom surface of the vehicle" can also be understood as a plane parallel to the driving plane of the vehicle. In the embodiment of the application, the "coverage area" can be understood as follows: when the antenna is a cellular antenna, the gain of the antenna in the coverage area can be above -5dBi, and the minimum gain value of the antenna in the coverage area is -8dBi; when the antenna is a satellite antenna, the gain of the antenna in the coverage area can be above -5dBic.

[0091] The communication module 11 is configured to switch from the initial working state to the first working state according to the relative pose information. For example, the first feed radiation body 31 can be arranged on the front windshield 212 of the vehicle body 20, and the first coverage area M1 can be an area in front of the vehicle body 20, and the coverage angle of at least part of the first coverage area M1 can be 90°. Here, the detection unit 113 can obtain the position of the satellite 80 relative to the first feed radiation body 31 according to the relative pose information. When the orthographic projection of the satellite 80 in the plane parallel to the bottom surface of the vehicle is located in the first coverage area M1, the first feed radiation body 31 transceives signals in the first coverage area M1.

[0092] In the initial working state, the control unit 115 controls the switching module 12 to couple the communication module 11 and the second feeding radiator 32, and the detection unit 113 can acquire the current latitude and longitude information of the vehicle, and further acquire the azimuth angle B of the vehicle body 20. That is, the relative position and posture information of the satellite 80 relative to the vehicle body 20 in the plane parallel to the bottom surface of the vehicle body 20 can be acquired. For example, in the initial working state, the satellite 80 is located in the front of the vehicle body 20 (that is, the azimuth angle B of the vehicle body 20 relative to the satellite 80 is 0 degrees) in the plane parallel to the bottom surface of the vehicle body 20, and the satellite 80 is located in the first coverage area M1 in the plane parallel to the bottom surface of the vehicle body 20. At this time, the communication module 11 is switched from the initial working state to the first working state according to the relative position and posture information, and the control unit 115 controls the switching module 12 to couple the communication module 11 and the first feeding radiator 31, so that the communication assembly 10 communicates with the satellite 80 through the first feeding radiator 31.

[0093] Through the above arrangement, in the first working state, the communication assembly 10 communicates through the first feeding radiator 31, which is conducive to improving the communication performance of the whole vehicle.

[0094] Exemplarily, the second feeding radiator 32 can be arranged on one side of the rear cover 215 of the vehicle body 20, and the second feeding radiator 32 is used as an antenna and transmits and receives signals in the second coverage area M2 in the plane parallel to the bottom surface of the vehicle body 20. In some examples, the communication module 11 can also have a second working state, and the control unit 115 can also be configured to control the switching module 12 to couple the communication module 11 and the second feeding radiator 32 in the second working state. The communication module 11 can also be configured to switch from the first working state to the second working state according to the relative position and posture information. The second coverage area M2 can be an area behind the vehicle body 20, and the coverage angle of at least part of the second coverage area M2 can be, for example, 270 degrees. Through the above arrangement, the second coverage area M2 and the first coverage area M1 can form an omnidirectional coverage to improve the communication performance of the vehicle.

[0095] With the driving of the vehicle, the position and posture of the vehicle relative to the satellite 80 also change. The detection unit 113 can acquire the current latitude and longitude information of the vehicle, and further acquire the azimuth angle B of the vehicle body 20. In the plane parallel to the bottom surface of the vehicle body 20, the satellite 80 is located in the right of the vehicle body 20 (that is, the azimuth angle B of the vehicle body 20 relative to the satellite 80 is 90 degrees), and the satellite 80 can be changed from being located in the first coverage area M1 to being located in the second coverage area M2. At this time, the communication module 11 is switched from the first working state to the second working state according to the relative position and posture information, and the control unit 115 controls the switching module 12 to couple the communication module 11 and the second feeding radiator 32, so that the communication assembly 10 communicates with the satellite 80 through the second feeding radiator 32.

[0096] Based on the above embodiments, the first feeding radiator 31 and the second feeding radiator 32 can each be used as a satellite 80 antenna, so that the first feeding radiator 31 and the second feeding radiator 32 can communicate with the satellite 80.

[0097] Figure 9 A horizontal pattern of a low band (LB) antenna in a vehicle provided by an embodiment of the present application; Figure 10 A horizontal pattern of a mid & high band (MHB) antenna in a vehicle provided by an embodiment of the present application. Figure 9 And Figure 10 The dashed line in FIGS. 1-3 is used to represent a radiation direction using only the plurality of feeding radiators 14 in the communication assembly 10 for communication, Figure 9 And Figure 10 The solid line in FIGS. 1-3 is used to represent a radiation direction using the plurality of feeding radiators 14 and the first feeding radiator 31 in the communication assembly 10 for communication. When the vehicle uses only the plurality of feeding radiators 14 in the communication assembly 10 for communication, and the communication assembly 10 is disposed on one side of the vehicle tail, the front of the vehicle (the range of the azimuth angle B is 90° to 270°) has an antenna gain defect due to the shielding effect of the vehicle body 20. As shown in FIG. 4, the antenna gain curve of the low band antenna is near the azimuth angle B 225° (e.g., at position 1 in FIG. 5), where the minimum gain of the antenna is only -23 dBi; as shown in FIG. 6, the antenna gain curve of the mid & high band antenna is near the azimuth angle B 196° (e.g., at position 1 in FIG. 7), where the minimum gain of the antenna is only -21 dBi. Figure 9 Figure 9 Figure 10 Figure 10 When the vehicle uses the plurality of feeding radiators 14 and the first feeding radiator 31 in the communication assembly 10 for communication, as shown in FIG. 8, the antenna gain of the low band antenna near the azimuth angle B 225° (e.g., at position 2 in FIG. 9) is approximately -8 dBi, as shown in FIG. 10, the antenna gain of the mid & high band antenna near the azimuth angle B 196° (e.g., at position 2 in FIG. 11) is approximately -7 dBi. Figure 9 Figure 9 Figure 10 Figure 10

[0098] Further, when the vehicle uses only the plurality of feeding radiators 14 in the communication assembly 10 for communication, and the communication assembly 10 is disposed on one side of the vehicle tail, the front of the vehicle (the range of the azimuth angle B is 90° to 270°) has an antenna dead spot. For example, the proportion of the antenna dead spot of the low band antenna in the plurality of feeding radiators 14 of the communication assembly 10 can be 25 / 180, and the proportion of the antenna dead spot of the mid & high band antenna can be 20 / 180. When the communication assembly 10 in the vehicle communicates through the first feeding radiator 31, the antenna dead spot can be improved.​​​​​​​

[0099] Further, when the vehicle only uses the plurality of feed radiators 14 in the communication assembly 10 to communicate, and the communication assembly 10 is arranged at one side of the vehicle tail, the minimum EIRP (Equivalent Isotropic Radiated Power) of the whole vehicle is low, wherein the minimum EIRP of the low-frequency antenna can be -0.5 dBm, and the minimum EIRP of the medium-high-frequency antenna can be 0.6 dBm. When the communication assembly 10 in the vehicle communicates through the first feed radiator 31, the minimum EIRP of the low-frequency antenna can be 11.7 dBm, and the minimum EIRP of the medium-high-frequency antenna can be 9.9 dBm.

[0100] In summary, the first feed radiator 31 and the second feed radiator 32 can jointly form an omnidirectional coverage effect, thereby improving the communication performance of the whole vehicle.

[0101] In some embodiments, part of the plurality of feed radiators 14 can form a main diversity antenna, and part of the plurality of feed radiators 14 can form at least one diversity antenna. The first feed radiator 31 and the main diversity antenna can be coupled to the communication module 11 through the switching module 12. The main diversity antenna can have the functions of receiving and transmitting signals, and the diversity antenna can have the function of receiving signals. Through the above arrangement, when the communication module 11 is coupled to the main diversity antenna, the communication module 11 can receive and transmit signals through the main diversity antenna, and when the communication module 11 is coupled to the first feed radiator 31, the communication module 11 can receive and transmit signals through the first feed radiator 31.

[0102] In some embodiments, in a plane parallel to the bottom surface of the vehicle, the first feed radiator 31 is used as an antenna and transceives signals in the first coverage area M1, and the second feed radiator 32 is used as an antenna and transceives signals in the second coverage area M2. The coverage angle of the first coverage area M1 is smaller than the coverage angle of the second coverage area M2.

[0103] For example, the first feed radiator 31 can be used as a first antenna, the first antenna can be a directional high-gain antenna, and the first antenna can transceive signals in the first coverage area M1. Similarly, the second feed radiator 32 can be used as a second antenna, the second antenna can be a directional high-gain antenna, and the second antenna can transceive signals in the second coverage area M2.

[0104] In some examples, the coverage angle of the coverage area can be adjusted by adjusting the feed radiators 14. For example, the feed radiators 14 can be beamformed; or, a metal piece can be arranged on the vehicle body 20 and can reflect the radiation beams of the feed radiators 14; or, the installation angle of the feed radiators 14 can be changed.

[0105] Since the coverage angle of the first coverage area M1 is smaller than the coverage angle of the second coverage area M2, when the vehicle communicates, the second feed radiators 32 are mainly used for communication, and the first feed radiators 31 are used to compensate for the gain defects of the second feed radiators 32, thereby improving the communication performance of the vehicle.

[0106] Alternatively, in some other examples, the second feed radiators 32 can be used as a second antenna, which can also be an omnidirectional antenna, and the second antenna can transmit and receive signals in the second coverage area M2. At this time, the coverage angle of the first coverage area M1 is smaller than the coverage angle of the second coverage area M2.

[0107] In some embodiments, the distance between the first feed radiators 31 and the second feed radiators 32 can be greater than or equal to 1 meter. For example, the distance between the first feed radiators 31 and the second feed radiators 32 can be 1 meter, 1.2 meters, 1.3 meters, or 1.5 meters. Through the above setting, it is beneficial to further avoid the antenna gain defects caused by the shielding of the vehicle body 20, so that the first feed radiators 31 and the second feed radiators 32 together form an omnidirectional coverage effect, and further improve the communication performance of the vehicle.

[0108] As shown in Figure 11 The frame 201 can include a top portion 21, a first side portion 22, and a second side portion 23. The top portion 21 extends from the front of the vehicle body 20 to the rear of the vehicle body 20. The first side portion 22 and the second side portion 23 are arranged along a first direction Y, and the top portion 21 is located between the first side portion 22 and the second side portion 23. The first direction Y is parallel to the chassis 202 of the vehicle and is perpendicular to a direction from the front of the vehicle body 20 to the rear of the vehicle body 20. Figure 11

[0109] For example, the top portion 21 can include a front cover 211, a front windshield 212, a top structural member 213, a rear windshield 214, and a rear cover 215 arranged in sequence from the front of the vehicle body 20 to the rear of the vehicle body 20.

[0110] In some examples, the communication assembly 10 can be located inside the top structural member 213. For example, as shown in Figure 11 ​As shown, the top structure 213 may include a first crossbeam 2131, a skylight glass 2135, and a spoiler 2136 arranged sequentially from the front of the vehicle body 20 to the rear of the vehicle body 20. The top structure 213 may also include a first luggage rack 2137 and a second luggage rack 2138 arranged along a first direction Y. The skylight glass 2135 may be located between the first luggage rack 2137 and the second luggage rack 2138, and both the first luggage rack 2137 and the second luggage rack 2138 may be located between the first crossbeam 2131 and the spoiler 2136. The communication component 10 may be disposed within the spoiler 2136, or the communication component 10 may be disposed within a metal plate located between the skylight glass 2135 and the spoiler 2136.

[0111] In some other examples, the communication component 10 can also be located on one side of the rear cover 215. Based on the above configuration, the first feed radiator 31 can be located on the front windshield 212 or the top structure 213. In some embodiments, the structure of the top structure 213 can be as described in the above embodiments and will not be repeated here. When the first feed radiator 31 is located on the top structure 213 in the above embodiments, the first feed radiator 31 can be located on one of the first crossbeam 2131, the skylight 2135, the first luggage rack 2137, the second luggage rack 2138, and the spoiler 2136.

[0112] Or, in some other embodiments, such as Figure 12 As shown, the structure of the top structure 213 may further include a first crossbeam 2131, a second crossbeam 2132, and a third crossbeam 2133 arranged sequentially from the front to the rear of the vehicle body 20. The first crossbeam 2131 may be an A-pillar crossbeam, the second crossbeam 2132 may be a B-pillar crossbeam, and the third crossbeam 2133 may be a C-pillar crossbeam. The top structure 213 may further include a sheet metal member disposed between the first crossbeam 2131 and the second crossbeam 2132, and a sheet metal member disposed between the second crossbeam 2132 and the third crossbeam 2133. When the first feed radiator 31 is disposed on the top structure 213, the first feed radiator 31 may be located on one of the first crossbeam 2131, the second crossbeam 2132, and the third crossbeam 2133.

[0113] Of course, the installation position of the first feeding radiator 31 may not be limited to the above embodiment, and the embodiment of the present application does not specifically limit the installation position of the first feeding radiator 31.

[0114] In summary, through the distributed arrangement of the first feeding radiator 31 and the second feeding radiator 32, one of the two feeding radiators 14 transmits and receives signals in the vehicle forward direction, and the other of the two feeding radiators 14 transmits and receives signals in the vehicle backward direction. When the second feeding radiator 32 has an antenna gain defect, the first feeding radiator 31 can compensate for the antenna gain defect, which is beneficial to avoid the antenna gain defect caused by the shielding of the vehicle body 20 and improve the communication performance of the whole vehicle.

[0115] The embodiment of the present application also provides another vehicle, referring to Figure 13 and Figure 14 The vehicle can include the first feeding radiator 31 and the second feeding radiator 32. The first feeding radiator 31 and the second feeding radiator 32 can be mounted on the frame 201. As described in the above embodiment, the first feeding radiator 31 and the second feeding radiator 32 are mounted on the frame 201, which can be understood as that the first feeding radiator 31 and the second feeding radiator 32 can be mounted inside the frame 201, or the first feeding radiator 31 and the second feeding radiator 32 can be mounted on the outer surface of the frame 201, or the first feeding radiator 31 and the second feeding radiator 32 can be mounted on the inner surface of the frame 201. The mounting mode of the first feeding radiator 31 and the second feeding radiator 32 can be as described in the above embodiment, which will not be described here. By mounting the first feeding radiator 31 and the second feeding radiator 32 on the frame 201, it is beneficial to avoid the shielding of the first feeding radiator 31 and the second feeding radiator 32 by the vehicle body 20.

[0116] The first feeding radiator 31 and the second feeding radiator 32 are both coupled with the communication assembly 10. Here, the feeding point of the first feeding radiator 31 and the feeding point of the second feeding radiator 32 can be coupled with the radio frequency chip in the communication assembly 10. The second feeding radiator 32 and the first feeding radiator 31 have the same working frequency band, and the first feeding radiator 31 and the second feeding radiator 32 jointly constitute an omnidirectional antenna. The omnidirectional antenna can be understood as described in the above embodiment, which will not be described here.

[0117] The distance between the first feeding radiator 31 and the second feeding radiator 32 is greater than 40 cm. Through the above arrangement, the first feeding radiator 31 and the second feeding radiator 32 have a certain distance, so that the first feeding radiator 31 and the second feeding radiator 32 can be relatively dispersedly distributed on the vehicle body 20, which is beneficial to the uniform radiation of the antenna composed of the first feeding radiator 31 and the second feeding radiator 32 in the directional diagram.

[0118] Through the above arrangement, when one feeding radiator 14 has an antenna gain defect, the other feeding radiator 14 can compensate for the antenna gain defect, so that the first feeding radiator 31 and the second feeding radiator 32 jointly form an omnidirectional coverage effect, thereby improving the communication performance of the whole vehicle.

[0119] For example, in some examples, the communication assembly 10 can include a cockpit domain controller (CDC), the first feeding radiator 31 can be coupled with the communication module 11 in the cockpit domain controller through the first radio frequency channel 13, and the second feeding radiator 32 can be coupled with the communication module 11 in the cockpit domain controller through the second radio frequency channel 13. The cockpit domain controller can be connected with the Internet of Vehicles terminal box through the cable 40, so that the cockpit domain controller can realize data interaction with the Internet of Vehicles terminal box. Continuing to refer to Figure 14 , the cockpit domain controller can also include other components. For example, the cockpit domain controller can also include a GNSS (Global Navigation Satellite System) antenna and a GNSS module, the GNSS antenna is coupled with the GNSS module to realize positioning of the whole vehicle. In addition, the cockpit domain controller can also include a Wi-Fi / BT module, which can be used to realize communication connection with the vehicle internal audio system, display system, etc. By arranging the first feeding radiator 31 and the second feeding radiator 32, the network signal strength in the whole vehicle can be improved, and the stability and reliability of network connection can be improved.

[0120] Further, the cockpit domain controller can also be coupled with an ultra-wideband (UWB) module, and the key located near the vehicle body 20 can be identified through the first feeding radiator 31 and the second feeding radiator 32, or the living body located in the vehicle body 20 can be detected through the first feeding radiator 31 and the second feeding radiator 32, so that the vehicle can realize man-machine interaction inside and outside the vehicle, for example, the key or the living body can unlock the vehicle and start the engine when it is close to the vehicle.

[0121] In some embodiments, in a plane parallel to the chassis 202 of the vehicle, the first feeding radiator 31 can be used as an antenna and transceive signals in the first coverage area M1, the second feeding radiator 32 can be used as an antenna and transceive signals in the second coverage area M2, and the coverage angle of at least part of the first coverage area M1 and the coverage angle of at least part of the second coverage area M2 can be complementary angles. Here, the "coverage area" can be understood as follows: when the antenna is a cellular antenna, the gain of the antenna in the coverage area can be above -5dBi, and the minimum gain value of the antenna in the coverage area is -8dBi; when the antenna is a satellite 80 antenna, the gain of the antenna in the coverage area can be above -5dBic.

[0122] Exemplarily, the first feeding radiator 31 can be used as a first antenna, the first antenna can be a directional high-gain antenna, and the first antenna can transceive signals within the first coverage area M1. Similarly, the second feeding radiator 32 can be used as a second antenna, the second antenna can be a directional high-gain antenna, and the second antenna can transceive signals within the second coverage area M2.

[0123] For example, the coverage angle of the first coverage area can be 180°, the coverage angle of the second coverage area M2 can be 180°, and the two coverage areas can cover 360° after superposition. Alternatively, the coverage angle of the first coverage area can be 180°, the coverage angle of the second coverage area M2 can be 270°, the first coverage area M1 and the second coverage area M2 can have an overlapping area, and the two coverage areas can cover 360° after superposition. Since at least part of the coverage angle of the first coverage area M1 and at least part of the coverage angle of the second coverage area M2 are supplementary angles, the first feeding radiator 31 and the second feeding radiator 32 together form the effect of omnidirectional coverage, thereby improving the communication performance of the whole vehicle.

[0124] Alternatively, in some examples, the first feeding radiator 31 can be used as a first antenna, and the first antenna can also be an omnidirectional antenna. Similarly, the second feeding radiator 32 can be used as a second antenna, and the second antenna can also be an omnidirectional antenna. At this time, the first antenna and the second antenna can also jointly constitute an omnidirectional antenna.

[0125] In some embodiments, the distance between the first feeding radiator 31 and the second feeding radiator 32 can be greater than or equal to 1 meter. For example, the distance between the first feeding radiator 31 and the second feeding radiator 32 can be 1 meter, 1.2 meters, 1.3 meters, or 1.5 meters. Through the above setting, it is beneficial to further avoid the antenna gain defect caused by the shielding of the vehicle body 20, so that the first feeding radiator 31 and the second feeding radiator 32 together form the effect of omnidirectional coverage, thereby further improving the communication performance of the whole vehicle.

[0126] As Figure 13 and Figure 15As shown, the frame 201 can include a top portion 21, a first side portion 22 and a second side portion 23, the top portion 21 extends from a front of the vehicle body 20 to a rear of the vehicle body 20, the first side portion 22 and the second side portion 23 are arranged along a first direction Y, the top portion 21 is between the first side portion 22 and the second side portion 23, the first direction Y is parallel to a chassis 202 of the vehicle, and is perpendicular to a direction from the front of the vehicle body 20 to the rear of the vehicle body 20. For example, the top portion 21 can include a front cover 211, a front windshield 212, a top structural member 213, a rear windshield 214 and a rear cover 215 arranged in sequence from the front of the vehicle body 20 to the rear of the vehicle body 20.

[0127] In some embodiments, the first feeding radiator 31 can be arranged on the top portion 21, and the second feeding radiator 32 can be arranged on the top portion 21. By arranging both the first feeding radiator 31 and the second feeding radiator 32 on the top portion 21 of the frame 201, one of the two feeding radiators 14 can be used to transmit and receive signals in a front direction of the vehicle, and the other of the two feeding radiators 14 can be used to transmit and receive signals in a rear direction of the vehicle, so that the first feeding radiator 31 and the second feeding radiator 32 together form an omnidirectional coverage effect, thereby improving the communication performance of the vehicle.

[0128] Further, as shown in Figure 13 and Figure 15 The first feeding radiator 31 can be arranged on the top portion 21, including that the first antenna can be arranged on one of the front windshield 212, the top structural member 213, the rear windshield 214 and the rear cover 215. Similarly, the second feeding radiator 32 can be arranged on the top portion 21, including that the first antenna can be arranged on one of the front windshield 212, the top structural member 213, the rear windshield 214 and the rear cover 215. Since neither the first feeding radiator 31 nor the second feeding radiator 32 is arranged on the front cover 211 of the frame 201, it is beneficial to avoid affecting the appearance of the vehicle and affecting the wind resistance of the vehicle.

[0129] When the first feeding radiator 31 and the second feeding radiator 32 are both arranged on the top portion 21, the first feeding radiator 31 and the second feeding radiator 32 can be located on different structural members of the top portion 21 to ensure a certain distance between the first feeding radiator 31 and the second feeding radiator 32, thereby ensuring the signal transmission and reception effect of the omnidirectional antenna formed by the first feeding radiator 31 and the second feeding radiator 32. For example, when the first feeding radiator 31 is located on the front windshield 212 of the top portion 21, the second feeding radiator 32 can be located on the top portion 21 of the frame 201 other than the front windshield 212, for example, the second feeding radiator 32 can be located on one of the top structural member 213, the rear windshield 214 and the rear cover 215.

[0130] The top structure 213 can have different structural components due to different vehicle models. In some embodiments, as shown in FIG. 2A, the vehicle can be a sedan model. The top structure 213 can include a first cross beam 2131, a second cross beam 2132, and a third cross beam 2133 arranged in sequence from the front of the vehicle body 20 to the rear of the vehicle body 20. The first cross beam 2131 can be an A-pillar cross beam, the second cross beam 2132 can be a B-pillar cross beam, and the third cross beam 2133 can be a C-pillar cross beam.

The top structure 213 can include a first cross beam 2131, a sunroof 2135, and a spoiler 2136 arranged in sequence from the front of the vehicle body 20 to the rear of the vehicle body 20. The top structure 213 can further include a first luggage rack 2137 and a second luggage rack 2138 arranged along the first direction Y. The sunroof 2135 can be located between the first luggage rack 2137 and the second luggage rack 2138, and the first luggage rack 2137 and the second luggage rack 2138 can both be located between the first cross beam 2131 and the spoiler 2136.

[0132] In some embodiments, as shown in FIG. 2B, the vehicle can be a sport utility vehicle (SUV) model. The top structure 213 can include a first cross beam 2131, a sunroof 2135, and a spoiler 2136 arranged in sequence from the front of the vehicle body 20 to the rear of the vehicle body 20. The top structure 213 can further include a first luggage rack 2137 and a second luggage rack 2138 arranged along the first direction Y.

When the second feeding radiator 32 is located on the top structure 213, the second feeding radiator 32 can be installed on one of the first crossbeam 2131, the portion of the skylight glass 2135 near the first crossbeam 2131, the first luggage rack 2137, the second luggage rack 2138, the portion of the skylight glass 2135 near the spoiler 2136, and the spoiler 2136. As described in the above embodiment, the first feeding radiator 31 and the second feeding radiator 32 can be located on different structures of the top structure 213. Exemplarily, when the first feeding radiator 31 is located on the first beam 2131 of the top structural member 213, the second feeding radiator 32 can be located on the top structural member 213 of the frame 201 other than the first beam 2131. For example, the second feeding radiator 32 can be located on a portion of the skylight glass 2135 close to the first beam 2131, a first luggage rack 2137, a second luggage rack 2138, a portion of the skylight glass 2135 close to the spoiler 2136, and one of the spoilers 2136.

Similarly, the second side portion 23 can include a second rearview mirror 231, a second front door 234, a second rear door 235, and a second triangular window 233, arranged sequentially from the front of the vehicle body 20 to the rear of the vehicle body 20. With this arrangement, one of the two feed radiators 14 can be primarily used to transmit and receive signals in the left direction of the vehicle, while the other of the two feed radiators 14 can be primarily used to transmit and receive signals in the right direction of the vehicle. This allows the first feed radiator 31 and the second feed radiator 32 to jointly provide omnidirectional coverage, thereby improving the communication performance of the entire vehicle.

[0135] In some embodiments, the first feeding radiator 31 is arranged on the first side portion 22, including: the first feeding radiator 31 is arranged on one of the first rearview mirror 221 and the first triangular window 223; and the second feeding radiator 32 is arranged on the second side portion 23, including: the second feeding radiator 32 is arranged on one of the second rearview mirror 231 and the second triangular window 233.

The feeding radiator arranged on the rearview mirror can be understood as that the feeding radiator is arranged in the shell of the rearview mirror. Wherein, the triangular window can be roughly triangular in shape, or the triangular window can also be in other shapes, which are not limited in the embodiments of the present application. The first triangular window 223 and the second triangular window 233 can be triangular windows adjacent to the C-pillar of the frame 201, so as to avoid the first feeding radiator 31 and the second feeding radiator 32 from blocking the view of the main driver or the co-driver.

[0136] For example, the first feeding radiator 31 and the second feeding radiator 32 can be symmetrically arranged relative to the central axial plane S of the vehicle body 20. For example, as shown in FIG. 2, when the first feeding radiator 31 is arranged on the first rearview mirror 221, the second feeding radiator 32 can be arranged on the second rearview mirror 231. Or, as shown in FIG. 3, when the first feeding radiator 31 is arranged on the first triangular window 223, the second feeding radiator 32 can be arranged on the second triangular window 233.

[0139] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
