Description

Technical Field

[0001] The present application relates to the technical field of phased array antennas, and in particular to a vehicle-mounted phased array antenna and a vehicle. Background Art

[0002] A phased array antenna (PAA) changes the shape of its radiation pattern by controlling the feed phase of the radiating elements in the array. Phase control changes the direction of the antenna pattern's maximum value, achieving beam scanning. By adjusting the signal phase differences between multiple antenna elements, precise control of the beam's direction and shape is achieved.

[0003] Because phased array antennas can complete omnidirectional scanning in microseconds without physical rotation by adjusting the phase difference, they have become core components in radar, communications, satellites and other fields due to their flexibility and efficiency. In recent years, phased array antennas have gradually been installed and applied to vehicles to achieve vehicle positioning.

[0004] However, all components of current phased array antennas are integrated into the same structure, resulting in a relatively large volume. Therefore, when used on a vehicle, it can only be mounted on the roof, causing the phased array antenna to protrude from the roof, affecting the smoothness and aesthetics of the vehicle structure. Summary of the Invention

[0005] Based on this, it is necessary to provide a vehicle-mounted phased array antenna and a vehicle to address the above technical problems, so as to improve the smoothness and aesthetics of the vehicle structure when the phased array antenna is deployed on the vehicle.

[0006] In a first aspect, the present application provides a vehicle-mounted phased array antenna, wherein the vehicle-mounted phased array antenna includes an antenna end and a phase controller, the antenna end and the phase controller are separately arranged, the antenna end is arranged on the roof light-transmitting structure of the vehicle, the phase controller is arranged on the vehicle, and the distance between the phase controller and the antenna end is less than a preset distance.

[0007] Based on the vehicle-mounted phased array antenna of this embodiment, the antenna end and phase controller of the vehicle-mounted phased array antenna are separately arranged, and the antenna end is arranged on the roof light-transmitting structure of the vehicle, while the phase controller is arranged at other locations of the vehicle. This allows the smaller antenna end to be arranged together with the roof light-transmitting structure, eliminating the need to arrange both the antenna end and the phase controller of the phased array antenna on the roof. This avoids the need for the vehicle-mounted phased array antenna to protrude from the roof, thereby improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0008] In some embodiments, the roof translucent structure of the vehicle includes: a first translucent structure portion having a transmittance greater than a first preset transmittance threshold, and a second translucent structure portion having a transmittance less than the first preset transmittance threshold, and the antenna end is arranged in the second translucent structure portion.

[0009] Based on the vehicle-mounted phased array antenna of this embodiment, by setting the antenna end in the second light-transmitting structure portion with lower light transmittance in the roof light-transmitting structure, the antenna end can be hidden in the portion with lower light transmittance in the roof light-transmitting structure, thereby realizing a hidden setting of the antenna end, which is more helpful in improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0010] In some embodiments, the second light-transmitting structure portion is located at an edge of the roof light-transmitting structure.

[0011] Based on this embodiment, since the edge position of the roof light-transmitting structure is the position where it connects with the main body structure of the vehicle, and the main body structure is usually an opaque structure, by setting the second light-transmitting structure part with lower light transmittance at the edge position of the roof light-transmitting structure, and setting the antenna end at the second light-transmitting structure part, it is more conducive to the hidden setting of the antenna end, thereby further helping to improve the smoothness and aesthetics of the vehicle body structure when the vehicle is equipped with a phased array antenna.

[0012] In some embodiments, the second light-transmitting structure portion is located at an edge of one side of the roof light-transmitting structure, and the antenna end is disposed at one end of the second light-transmitting structure portion.

[0013] Based on this embodiment, by only setting a second light-transmitting structure portion with lower light transmittance on the edge of one side of the roof light-transmitting structure, and setting the antenna end at one end of the second light-transmitting structure portion with lower light transmittance, the antenna end can be hidden at the position set at one end of the second light-transmitting structure portion, and other devices can be hidden at the other end of the second light-transmitting structure portion, which is more helpful to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0014] In some embodiments, the vehicle is also provided with a remote communication terminal located at the other end of the second light-transmitting structure part, and the antenna end includes a transmitting array surface and a receiving array surface. The transmitting array surface is arranged on the side of the antenna end away from the remote communication terminal, and the receiving array surface is arranged on the side of the antenna end close to the remote communication terminal.

[0015] Based on this embodiment, by arranging the receiving array of the antenna end on the side of the antenna end close to the remote communication terminal, it is helpful to increase signal isolation and signal strength of the received signal.

[0016] In some embodiments, the light-transmitting structure of the roof of the vehicle includes: a fixed portion, and a movable portion that moves relative to the fixed portion, and the antenna end is disposed on the fixed portion.

[0017] Based on this embodiment, when the vehicle's roof light-transmitting structure includes a fixed part and a movable part that moves relative to the fixed part, by setting the antenna end at the fixed part, the influence of the signal strength of the signal received by the antenna end during or after the movement of the movable part can be avoided, thereby helping to maintain and ensure the communication performance of the vehicle-mounted phased array antenna.

[0018] In some embodiments, the position of the movable portion after moving relative to the fixed portion is located on a side adjacent to the interior space of the vehicle, and the fixed portion is located on a side away from the interior space of the vehicle.

[0019] Based on this embodiment, after the movable part of the roof light-transmitting structure moves relative to the fixed part, the movable part is located on the side adjacent to the interior space of the vehicle, while the fixed part is located on the side away from the interior space of the vehicle. Therefore, after the movable part moves relative to the fixed part, the fixed part can be located on the side away from the interior space of the vehicle, thereby further avoiding the impact of the movement of the movable part on the signal strength of the received signal at the antenna end, thereby helping to further maintain and ensure the communication performance of the vehicle-mounted phased array antenna.

[0020] In some embodiments, the fixed portion includes a third light-transmitting structure portion having a transmittance greater than a second preset light-transmitting threshold, and a fourth light-transmitting structure portion having a transmittance less than the second preset light-transmitting threshold, and the antenna end is arranged at the fourth light-transmitting structure portion, wherein the above-mentioned first light-transmitting structure portion includes the third light-transmitting structure portion, the second light-transmitting structure portion includes the fourth light-transmitting structure portion, and the first preset light-transmitting threshold includes the second preset light-transmitting threshold.

[0021] Based on this embodiment, by setting the antenna end in the fourth light-transmitting structure part with lower light transmittance of the fixed part, the antenna end can be hidden in the part with lower light transmittance of the fixed end in the roof light-transmitting structure, thereby realizing the hidden setting of the antenna end, which is more helpful for vehicles with movable sunroofs to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0022] In some embodiments, the fourth light-transmitting structure portion is located at an edge of the fixed portion away from the movable portion.

[0023] Based on this embodiment, since the fixed part of the roof light-transmitting structure is far away from the edge of the movable part and is located in contact with the main body structure of the vehicle, and the main body structure of the vehicle is usually an opaque structure, by setting the fourth light-transmitting structure part with lower light transmittance at a position away from the edge of the movable part of the fixed part, and setting the antenna end at the fourth light-transmitting structure part, it is more conducive to the hidden setting of the antenna end, thereby being more helpful for vehicles with movable sunroofs, and improving the smoothness and aesthetics of the body structure when the phased array antenna is deployed.

[0024] In some embodiments, the antenna end is disposed at one end of the fourth light-transmitting structure portion.

[0025] Based on this embodiment, by setting the antenna end at one end of the fourth light-transmitting structure part with a lower transmittance of the fixed part, the antenna end can be hidden at the position of one end of the fourth light-transmitting structure part set at the fixed part, and the other end of the fourth light-transmitting structure part can be hidden to set other devices, which is more helpful to improve the smoothness and aesthetics of the vehicle body structure when the vehicle is equipped with a phased array antenna.

[0026] In some embodiments, the vehicle is also provided with a remote communication terminal located at the other end of the fourth light-transmitting structure portion of the fixed part, and the antenna end includes a transmitting array surface and a receiving array surface. The transmitting array surface is arranged on the side of the antenna end away from the remote communication terminal, and the receiving array surface is arranged on the side of the antenna end close to the remote communication terminal.

[0027] In some embodiments, the roof light-transmitting structure includes a first light-transmitting structure and a second light-transmitting structure that are stacked together. The first light-transmitting structure is arranged on the side of the vehicle away from the interior space of the vehicle, and the antenna end is arranged between the first light-transmitting structure and the second light-transmitting structure.

[0028] The vehicle-mounted phased array antenna based on this embodiment is configured such that the roof light-transmitting structure includes a first light-transmitting structure and a second light-transmitting structure that are stacked, and the antenna end is disposed between the first light-transmitting structure and the second light-transmitting structure. The first light-transmitting structure and the second light-transmitting structure of the roof light-transmitting structure are usually sealed, thereby helping to improve the sealing performance of the antenna end, and to a certain extent reducing the problems of rain erosion and dust accumulation caused by long-term exposure of the antenna end to the air, and helping to improve the stability of signal reception at the antenna end.

[0029] In some embodiments, the antenna end is disposed on a side of the roof light-transmitting structure close to the interior space of the vehicle.

[0030] Based on this embodiment, by arranging the antenna end on the side of the roof light-transmitting structure close to the interior space of the vehicle, it is more conducive to the installation and arrangement of the antenna end, and is more convenient to install the antenna end relative to the roof transparent structure.

[0031] In some embodiments, the antenna end includes a first antenna unit layer and a phase modulation chip, and the first antenna unit layer and the phase modulation chip are arranged on a side of the roof light-transmitting structure close to the interior space of the vehicle.

[0032] Based on this embodiment, by arranging the first antenna unit layer and the phase-modulating chip of the antenna end on the side of the roof light-transmitting structure close to the interior space of the vehicle, it is more conducive to the installation of the first antenna unit layer and the phase-modulating chip, and is conducive to the convenience of installing the antenna end and the roof transparent structure. By laminating the first antenna unit layer and the phase-modulating chip, the demand for the structural design of the phase-modulating chip can be reduced. For example, there is no need to set up special dielectric materials and other structures, which further reduces the thickness of the antenna end structure and is more conducive to the convenience of setting and installing the antenna end.

[0033] In some embodiments, the antenna end further includes a second antenna unit layer, and the second antenna unit layer is arranged on a side of the first antenna unit layer away from the interior space of the vehicle.

[0034] Based on this embodiment, by arranging a second antenna unit layer on the side of the first antenna unit layer away from the interior space of the vehicle, and by further adding the second antenna unit layer, the signal loss caused by the signal shielding of the first antenna unit layer by the roof light-transmitting structure can be supplemented, which helps to ensure the communication performance of the antenna end.

[0035] In some embodiments, the roof light-transmitting structure includes a first light-transmitting structure and a second light-transmitting structure that are stacked together, the first light-transmitting structure is arranged on the side of the vehicle away from the interior space of the vehicle, and the antenna end also includes a second antenna unit layer, which is arranged between the first light-transmitting structure and the second light-transmitting structure.

[0036] Based on this embodiment, by setting the roof light-transmitting structure to include a first layer of light-transmitting structure and a second layer of light-transmitting structure arranged in a stacked manner, and setting the second antenna unit layer between the first layer of light-transmitting structure and the second layer of light-transmitting structure, the problems of rain erosion and dust accumulation caused by long-term exposure of the second antenna unit layer to the air can be reduced, which helps to improve the stability and strength of signal reception at the antenna end.

[0037] In some embodiments, the second antenna unit layer is disposed on a side of the first light-transmitting structure that is adjacent to the second light-transmitting structure.

[0038] Based on this embodiment, by arranging the second antenna unit layer at the antenna end on the side of the first light-transmitting structure adjacent to the second light-transmitting structure, the rain erosion and dust accumulation problems caused by the long-term exposure of the second antenna unit layer to the air can be reduced, while the second antenna unit layer is placed closer to the external space of the vehicle, which can help to further improve the stability and strength of the sending and receiving signals at the antenna end, and help to further ensure the communication performance of the antenna end.

[0039] In some embodiments, the second antenna unit layer is printed and disposed on a side of the first light-transmitting structure that is adjacent to the second light-transmitting structure.

[0040] Based on this embodiment, by printing and arranging the second antenna unit layer on the side of the first light-transmitting structure adjacent to the second light-transmitting structure, a planar structural design of the second antenna unit layer can be achieved, which can significantly reduce the overall volume and is more conducive to improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0041] In some embodiments, the operating frequency of the second antenna element layer is the same as the operating frequency of the first antenna element layer.

[0042] Based on this embodiment, by setting the communication frequency of the second antenna unit layer to be the same as the communication frequency of the first antenna unit layer, it can be more conducive to making the peaks and troughs of the signal generated by the first antenna unit layer overlap with the peaks and troughs of the signal generated by the second antenna unit layer, and is more conducive to supplementing the signal energy loss caused by the signal blocking of the first antenna unit layer by the roof light-transmitting structure, which helps to ensure and improve the communication performance of the antenna end.

[0043] In some embodiments, the second antenna unit layer is communicatively connected to the first antenna unit layer via a feeder line.

[0044] By communicatively connecting the second antenna unit layer with the first antenna unit layer via a feeder line, the installation complexity of the second antenna unit layer is reduced, and the installation convenience of various components at the antenna end, such as the second antenna unit layer, is improved.

[0045] In some embodiments, the antenna end is integrated with the roof light-transmitting structure.

[0046] Based on this embodiment, by integrating the antenna end with the roof light-transmitting structure, it helps to further reduce the complexity of installation, and is more helpful to reduce external components, which is more conducive to improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0047] In some embodiments, the phase controller is disposed on a main body structure of the vehicle adjacent to the roof light-transmitting structure.

[0048] Based on this embodiment, by setting the phase controller that is separated from the antenna end on the main body structure of the vehicle body adjacent to the roof light-transmitting structure, the distance between the phase controller and the antenna end can be better controlled while the phase controller and the antenna end are set separately. In addition, by setting the phase controller on the main body structure of the vehicle body, it is also helpful to improve the convenience of setting the phase controller.

[0049] In some embodiments, the distance between the phase controller and the roof light-transmitting structure is within a preset range, and an upper limit of the preset range is less than the preset distance.

[0050] Based on this embodiment, by setting the phase controller at a position within a preset range of the distance from the roof light-transmitting structure, and since the antenna end is set on the roof light-transmitting structure, the distance between the phase controller and the antenna end is controlled based on the control of the distance from the roof light-transmitting structure, which helps to facilitate and improve the efficiency of the phase controller position setting, and can reduce the impact of vibrations caused by the vehicle during driving on the devices set under the roof light-transmitting structure.

[0051] In some embodiments, the phase controller is disposed on the main body structure of the vehicle body adjacent to and below the roof light-transmitting structure where the antenna end is located.

[0052] Based on the vehicle-mounted phased array antenna of this embodiment, by setting the phase controller on the vehicle body main structure adjacent to the roof light-transmitting structure where the antenna end is located, the phase controller can be set as close to the antenna end as possible, which helps to improve the signal transmission performance between the antenna end and the phase controller, and thus helps the communication performance of the vehicle-mounted phased array antenna.

[0053] In some embodiments, the phase controller is disposed on the vehicle body main structure adjacent to a first side of the first light-transmitting structure portion, and the first side of the first light-transmitting structure portion is a side away from the second light-transmitting structure portion.

[0054] Based on the vehicle-mounted phased array antenna of this embodiment, by arranging the phase controller at a position adjacent to the first light-transmitting structure portion with relatively high light transmittance in the vehicle-mounted light-transmitting structure, and at a position adjacent to the first side of the first light-transmitting structure portion on the main body structure of the vehicle body, and the first side of the first light-transmitting structure portion is a side away from the second light-transmitting structure portion with relatively low light transmittance, it is unnecessary to limit the phase controller to a position adjacent to the antenna end, and the phase controller can be set based on the volume of the vehicle body, which helps to further improve the convenience of determining the setting position of the phase controller.

[0055] In some embodiments, the preset range includes 20-35 mm.

[0056] Based on the vehicle-mounted phased array antenna of this embodiment, by setting the phase controller at a distance of 20-35 mm from the roof light-transmitting structure, the phase controller can be placed as close as possible to the main body structure of the vehicle body while maintaining the communication performance between the phase controller and the antenna end. This is more conducive to the stealth setting of the phase controller, and also helps to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed. It can also reduce the impact of vibrations caused by the vehicle during driving on the devices arranged below the roof light-transmitting structure.

[0057] In a second aspect, the present application also provides a vehicle, wherein the vehicle includes a main body structure and a roof light-transmitting structure, wherein the vehicle is also provided with a vehicle-mounted phased array antenna according to any of the embodiments described above.

[0058] Based on the vehicle of this embodiment, by deploying a vehicle-mounted phased array antenna with a separate antenna end and phase controller on the vehicle, and setting the antenna end on the vehicle's roof light-transmitting structure, and setting the phase controller at other locations on the vehicle, the smaller antenna end can be set together with the roof light-transmitting structure, and there is no need to set both the antenna end and the phase controller of the phased array antenna on the roof, avoiding the need for the phased array antenna to protrude from the roof, and improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0077] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0078] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0079] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0080] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0081] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0082] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0083] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0084] Phased array antennas, with their flexibility and efficiency, have become core components in radar, communications, satellites, and other fields because they can complete omnidirectional beam scanning in microseconds by adjusting phase differences without the need for physical rotation. However, all components of current phased array antennas are integrated into a single structure, resulting in a relatively large size. Therefore, when phased array antennas are applied to vehicles, they can only be mounted on the roof. With this setup, the phased array antenna needs to protrude from the roof, affecting the fluidity and aesthetics of the vehicle structure.

[0085] After research, it was found that the antenna end of the phased array antenna that sends and receives signals and performs phase control on the antenna, and the phase controller that performs phase calculation and phase control can be separated, and the positions of the antenna end and the phase controller on the vehicle can be set according to the characteristics of the vehicle. This can achieve the communication function of the phased array antenna and meet the communication needs of the vehicle. At the same time, it can avoid the need for the phased array antenna to protrude outward from the roof of the vehicle, thereby improving the smoothness and aesthetics of the vehicle body structure after the phased array antenna is deployed.

[0086] Accordingly, the present application provides a vehicle-mounted phased array antenna, wherein the vehicle-mounted phased array antenna includes an antenna end and a phase controller, the antenna end and the phase controller are separately arranged, the antenna end is arranged on the roof translucent structure of the vehicle, the phase controller is arranged on the vehicle, and the distance between the phase controller and the antenna end is less than a preset distance.

[0087] Among them, the antenna end is the part of the vehicle-mounted phased array antenna used for sending and receiving signals, as well as for phase control of the antenna. It can perform the action of phase adjustment of the antenna so that the antenna radiates in a specified direction for beam scanning and control.

[0088] The phase controller is the part of the vehicle-mounted phased array antenna that is used to calculate the specific phase modulation phase for phase modulation control and can communicate with other devices that need to use positioning information.

[0089] The antenna and phase controller are separated, meaning they are set up as two independent devices, allowing them to be placed in different locations to suit different scenarios. By separating the antenna and phase controller, they can be positioned as needed.

[0090] The roof light-transmitting structure is located on the top of the vehicle and allows light to pass through. Figure 1 As shown, the vehicle roof light-transmitting structure 10 is located on the top of the vehicle 1000. In a specific example, the vehicle roof light-transmitting structure can be a skylight on the top of the vehicle.

[0091] The specific position of the sunroof on the vehicle roof and the proportion of the area occupied by the sunroof on the vehicle roof are not limited. For example, the roof light-transmitting structure 10 can be set in the area of ​​the roof near the front windshield 401, such as Figure 2 As shown in (1), at this time, the area of ​​the roof light-transmitting structure 10 is relatively small relative to the overall area of ​​the roof. In a specific example, the area of ​​the roof light-transmitting structure 10 relative to the area between the front windshield 401 and the rear windshield 402 of the roof can be smaller than a certain preset ratio (which can be referred to as the first preset ratio in the embodiment of the present application).

[0092] For another example, the roof light-transmitting structure 10 can be arranged in most of the area between the front windshield 401 and the rear windshield 402 of the roof, such as Figure 2 As shown in (2), at this time, the ratio of the area of ​​the roof light-transmitting structure 10 to the area between the front windshield 401 and the rear windshield 402 of the roof can be greater than a certain preset ratio (which can be referred to as the second preset ratio in the embodiment of the present application). The first preset ratio and the second preset ratio can be the same or different. The specific data of the first preset ratio and the second preset ratio can be set based on the vehicle model structure, etc.

[0093] For another example, the roof light-transmitting structure 10 can be arranged in the entire area between the front windshield 401 and the rear windshield 402 of the roof, so that when viewed from the outside of the vehicle, a panoramic skylight visual effect is presented, such as Figure 2 (3) As shown. It is understandable that, in the case of presenting the visual effect of a panoramic skylight, corresponding connection structures and / or support structures may be provided at the position where the front windshield 401 is connected to the roof perspective structure 10, and at the position where the rear windshield 402 is connected to the roof perspective structure 10, but this embodiment of the present application does not specifically show this.

[0094] It is understood that in other embodiments, the specific position, shape, and layout of the roof light-transmitting structure 10 on the roof can also be configured in other ways. The specific material of the roof light-transmitting structure 10 is not limited. For example, in some examples, the roof light-transmitting structure can be made of glass or other materials, but is not limited thereto.

[0095] refer to Figure 1 As shown, the antenna end 201 of the vehicle-mounted phased array antenna is set on the roof light-transmitting structure 10 of the vehicle 1000, and the phase controller ( Figure 1 、 2 (not shown) is set at a position where the distance between the vehicle 1000 and the antenna end 10 is less than a preset distance, so that the antenna end 201 and the phase controller can communicate with each other while meeting the requirements of the separate setting.

[0096] The specific setting method of the specific value of the preset distance can be set according to specific needs, as long as it can meet the communication requirements between the antenna end 201 and the phase controller. For example, the preset distance in some examples can be set to 1.5 meters (m), but is not limited thereto.

[0097] Based on the vehicle-mounted phased array antenna of this embodiment, the antenna end and phase controller of the vehicle-mounted phased array antenna are separately arranged, and the antenna end is arranged on the roof light-transmitting structure of the vehicle, while the phase controller is arranged at other locations of the vehicle. This allows the smaller antenna end to be arranged together with the roof light-transmitting structure, eliminating the need to arrange both the antenna end and the phase controller of the phased array antenna on the roof. This avoids the need for the vehicle-mounted phased array antenna to protrude from the roof, thereby improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0098] Among them, the specific structure of the roof light-transmitting structure is not limited. In some embodiments, the roof light-transmitting structure includes: a first light-transmitting structure part with a transmittance greater than a first preset light-transmitting threshold, and a second light-transmitting structure part with a transmittance less than the first preset light-transmitting threshold, and the antenna end is arranged in the second light-transmitting structure part.

[0099] Light transmittance is a parameter that indicates the ability of light to pass through a medium, and can be calculated by calculating the percentage of the luminous flux passing through the medium to its incident luminous flux, wherein the medium is usually a transparent or translucent medium. In the relevant embodiments of the present application, the medium of the transparent roof structure may include glass, but is not limited to this.

[0100] The specific value of the first preset light transmittance threshold is not limited, as long as it can distinguish the first light-transmitting structure portion and the second light-transmitting structure portion with different light transmittances. In some specific examples, the first preset light transmittance threshold may include a first threshold and a second threshold, and the first threshold is greater than the second threshold. The light transmittance of the first light-transmitting structure portion is greater than the first threshold, so that more light can pass through the first light-transmitting structure portion to reach the interior space of the vehicle. The light transmittance of the second light-transmitting structure portion is less than the second threshold, so that the light that passes through the second light-transmitting structure portion to reach the interior space of the vehicle can be minimized, or even no light passes through the second light-transmitting structure portion to reach the interior space of the vehicle.

[0101] Since the transmittance of the second light-transmitting structure part is smaller than that of the first light-transmitting structure part, by setting the antenna end in the second light-transmitting structure part with lower transmittance, it is possible to reduce the impact of the setting of the antenna end on the light reaching the interior space of the vehicle, and also minimize the visibility of the antenna end, thereby realizing the hidden setting of the antenna end.

[0102] Among them, the first light-transmitting structure part and the second light-transmitting structure part can be an integrally formed setting. For example, in the process of forming the roof light-transmitting structure, the medium of the first light-transmitting structure part and the second light-transmitting structure part, the arrangement of the medium, etc. can be set so that the integrally formed first light-transmitting structure part and the second light-transmitting structure part have different light transmittances. In other examples, after the roof light-transmitting structure with the same light transmittance is obtained by integrally forming, a low-transmittance film is superimposed on the area of ​​the second light-transmitting structure part, such as by gluing a low-transmittance film, to obtain a second light-transmitting structure part with even lower light transmittance. It is understandable that a roof light-transmitting structure with different light transmittances can also be obtained by other methods, and the embodiments of the present application do not impose specific limitations.

[0103] Based on the vehicle-mounted phased array antenna of this embodiment, by setting the antenna end in the second light-transmitting structure portion with lower light transmittance in the roof light-transmitting structure, the antenna end can be hidden in the portion with lower light transmittance in the roof light-transmitting structure, thereby realizing a hidden setting of the antenna end, which is more helpful in improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0104] The specific position of the second light-transmitting structure portion in the roof light-transmitting structure is not limited. In some examples, the second light-transmitting structure portion is located at the edge of the roof light-transmitting structure.

[0105] The edge of the roof light-transmitting structure refers to the peripheral part of the roof light-transmitting structure. By arranging the second light-transmitting structure part with lower light transmittance at the edge of the roof light-transmitting structure, and arranging the first light-transmitting structure part with higher light transmittance at the center part of the roof light-transmitting structure, the light transmittance of the center part of the roof light-transmitting structure is not affected, so that the light outside the vehicle can be projected into the interior space of the vehicle through the center part of the roof light-transmitting structure as much as possible.

[0106] Among them, the edge of the roof light-transmitting structure is the position where the roof light-transmitting structure is connected with other parts of the vehicle, such as the position where it is connected with the main structure of the vehicle body. Therefore, by setting the second light-transmitting structure part at the edge of the roof light-transmitting structure and setting the antenna end at the second light-transmitting structure part, it is more conducive to the hidden setting of the antenna end in the roof light-transmitting structure.

[0107] Based on this embodiment, since the edge position of the roof light-transmitting structure is the position where it connects with the main body structure of the vehicle, and the main body structure is usually an opaque structure, by setting the second light-transmitting structure part with lower light transmittance at the edge position of the roof light-transmitting structure, and setting the antenna end at the second light-transmitting structure part, it is more conducive to the hidden setting of the antenna end, thereby further helping to improve the smoothness and aesthetics of the vehicle body structure when the vehicle is equipped with a phased array antenna.

[0108] The second light-transmitting structure portion with lower light transmittance may be provided on each side edge of the roof light-transmitting structure, or the second light-transmitting structure portion may be provided on only one side edge of the roof light-transmitting structure. In the relevant embodiments of the present application, the second light-transmitting structure portion may be located on one side edge of the roof light-transmitting structure, and the first light-transmitting structure portion may be located on the other side of the roof light-transmitting structure.

[0109] In the relevant embodiment, the second light-transmitting structure portion can be located at the edge of any side of the roof light-transmitting structure. In the embodiment of the present application, refer to Figure 3 As shown, the second light-transmitting structure portion 112 can be arranged on the side of the roof light-transmitting structure close to the rear of the vehicle. At this time, the first light-transmitting structure portion 111 is located on the side of the roof light-transmitting structure close to the front of the vehicle.

[0110] The second light-transmitting structure portion 112 is provided at one side edge of the roof light-transmitting structure 10 , and the antenna end may be provided at one end of the second light-transmitting structure portion 112 .

[0111] Based on this embodiment, by only setting a second light-transmitting structure portion with lower light transmittance on the edge of one side of the roof light-transmitting structure, and setting the antenna end at one end of the second light-transmitting structure portion with lower light transmittance, the antenna end can be hidden at the position set at one end of the second light-transmitting structure portion, and other devices can be hidden at the other end of the second light-transmitting structure portion, which is more helpful to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0112] There is no limitation on the device provided at the other end of the second light-transmitting structure portion 112. In some embodiments of the present application, reference is made to Figure 4 As shown, the antenna end 201 is provided at one end of the second light-transmitting structure portion 112 , and the vehicle 1000 is further provided with a TBOX (Telematics Box, a remote communication terminal, referred to as TBOX in the following embodiments) 30 located at the other end of the second light-transmitting structure portion 112 .

[0113] A TBOX is a vehicle-mounted communication module whose core function is to establish a connection between the vehicle and an external network. The vehicle-mounted phased array antenna provided in the embodiments of this application is a communication device that enables the vehicle to communicate with the outside world and locate itself. Therefore, by placing the antenna end at one end of the second light-transmitting structural portion 112 and the TBOX at the other end of the second light-transmitting structural portion 112, the antenna end and the TBOX can be concealed while being located close to each other, further improving the vehicle's communication performance.

[0114] The antenna end 201 may include a transmitting array and a receiving array. In some examples, the transmitting array is arranged on a side of the antenna end 201 away from the TBOX30, and the receiving array is arranged on a side of the antenna end 201 close to the TBOX30. Figure 5 As shown, the transmitting array 2012 is disposed on the right side of the antenna end 201 , and the receiving array 2011 is disposed on the left side of the antenna end 201 , closer to the TBOX.

[0115] The transmitting array is the antenna array in a phased array antenna used to transmit electromagnetic waves in a direction toward the target area. The receiving array is the antenna array in a phased array antenna used to receive electromagnetic wave signals and convert them into electrical signals for subsequent processing. By placing the receiving array close to the TBOX, the signal strength received by the receiving array can be increased, thereby improving the isolation between the transmitted and received signals.

[0116] Based on this embodiment, by arranging the receiving array of the antenna end on the side of the antenna end close to the TBOX, it is helpful to increase signal isolation and signal strength of the received signal.

[0117] Other structural forms of the roof light-transmitting structure are not limited. For example, the roof light-transmitting structure can be a monolithic structure or comprise multiple distinct components. For example, in the case of a roof light-transmitting structure that utilizes glass to achieve light transmission, the roof light-transmitting structure can comprise a single piece of glass or multiple pieces of glass spliced ​​together. In some specific examples of the present application, the vehicle roof light-transmitting structure includes: a fixed portion; and a movable portion that moves relative to the fixed portion, with the antenna end disposed on the fixed portion.

[0118] The fixed portion is the immovable, non-displaceable part of the roof's light-transmitting structure, while the movable portion is the part that can move or displace relative to it. By fixing or moving the movable portion relative to the fixed portion, air can flow between the vehicle's interior and exterior spaces, or not, as needed, through the corresponding position of the movable portion.

[0119] The specific areas, shapes, and relative positions of the fixed portion and the movable portion in the roof light-transmitting structure are not limited. In some examples, the fixed portion may be located on the side of the roof light-transmitting structure close to the rear of the vehicle, while the movable portion may be located on the side of the roof light-transmitting structure close to the front of the vehicle, such as Figure 6 As shown, the roof light-transmitting structure includes a fixed portion 121 and a movable portion 122 , and the movable portion 122 can move relative to the fixed portion 121 .

[0120] The antenna end is arranged at the fixed portion, so that when the movable portion moves, the antenna end does not move along with the movement of the movable portion, which helps to improve the stability of the communication performance of the antenna end.

[0121] Among them, when the transparent structure of the roof includes a first light-transmitting structure part with higher light transmittance and a second light-transmitting structure part with lower light transmittance, the second light-transmitting structure part can be arranged on the side of the fixed part close to the rear of the vehicle, and the antenna end can be arranged at one end of the second light-transmitting structure part, and the TBOX can be arranged at the other end of the second light-transmitting structure part, so that the stability of the communication performance of the antenna end can be improved while realizing the hidden setting of the antenna end.

[0122] Based on this embodiment, when the vehicle's roof light-transmitting structure includes a fixed part and a movable part that moves relative to the fixed part, by setting the antenna end at the fixed part, the influence of the signal strength of the signal received by the antenna end during or after the movement of the movable part can be avoided, thereby helping to maintain and ensure the communication performance of the vehicle-mounted phased array antenna.

[0123] The relative positions of the movable portion and the fixed portion before and after movement are not limited. In some examples, when the air inside and outside the vehicle does not circulate through the area where the roof light-transmitting structure is located, the movable portion 122 and the fixed portion 121 can be in the same plane, or there is no height difference or no obvious height difference at the junction of the movable portion 122 and the fixed portion 121, such as Figure 7 (1). After the movable portion moves relative to the fixed portion, the position of the movable portion 122 relative to the fixed portion 121 is located on the side adjacent to the vehicle interior space, and the fixed portion 121 is located on the side away from the vehicle interior space, as shown in FIG. Figure 7 (2) shown.

[0124] Combine Figure 7 As shown, after the movable portion 122 moves relative to the fixed portion 121, the movable portion 122 is located on the side adjacent to the interior space of the vehicle, and the fixed portion 121 is located on the side away from the interior space of the vehicle, that is, the movable portion 122 is located below the fixed portion 121. At this time, for the antenna end 201 provided on the fixed portion 121, the distance relative to the external space of the vehicle does not change, so that before and after the movement of the movable portion, the communication performance of the antenna end will not be affected by the movement of the movable portion.

[0125] Based on this embodiment, after the movable part of the roof light-transmitting structure moves relative to the fixed part, the movable part is located on the side adjacent to the interior space of the vehicle, while the fixed part is located on the side away from the interior space of the vehicle. Therefore, after the movable part moves relative to the fixed part, the fixed part can be located on the side away from the interior space of the vehicle, thereby further avoiding the impact of the movement of the movable part on the signal strength of the received signal at the antenna end, thereby helping to further maintain and ensure the communication performance of the vehicle-mounted phased array antenna.

[0126] Continue to refer Figure 6As shown, the fixing portion 121 may include a third light-transmitting structure portion 113 having a transmittance greater than a second preset light-transmitting threshold, and a fourth light-transmitting structure portion 114 having a transmittance less than the second preset light-transmitting threshold, and the antenna end 201 is arranged at the fourth light-transmitting structure portion 114, wherein the above-mentioned first light-transmitting structure portion 111 includes the third light-transmitting structure portion 113, the second light-transmitting structure portion 112 includes the fourth light-transmitting structure portion 114, and the first preset light-transmitting threshold includes the second preset light-transmitting threshold.

[0127] Based on this embodiment, by setting the antenna end in the fourth light-transmitting structure part with lower light transmittance of the fixed part, the antenna end can be hidden in the part with lower light transmittance of the fixed end in the roof light-transmitting structure, thereby realizing the hidden setting of the antenna end, which is more helpful for vehicles with movable sunroofs to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0128] The position of the fourth light-transmitting structure portion 114 on the fixed portion is not limited. In some specific examples, the fourth light-transmitting structure portion 114 is located at an edge of the fixed portion away from the movable portion.

[0129] Based on this embodiment, since the fixed part of the roof light-transmitting structure is far away from the edge of the movable part and is located in contact with the main body structure of the vehicle, and the main body structure of the vehicle is usually an opaque structure, by setting the fourth light-transmitting structure part with lower light transmittance at a position away from the edge of the movable part of the fixed part, and setting the antenna end at the fourth light-transmitting structure part, it is more conducive to the hidden setting of the antenna end, thereby being more helpful for vehicles with movable sunroofs, and improving the smoothness and aesthetics of the body structure when the phased array antenna is deployed.

[0130] The position of the antenna end at the edge of the fourth light-transmitting structure portion is not limited. In some specific examples, the antenna end is disposed at one end of the fourth light-transmitting structure portion.

[0131] Based on this embodiment, by setting the antenna end at one end of the fourth light-transmitting structure part with a lower transmittance of the fixed part, the antenna end can be hidden at the position of one end of the fourth light-transmitting structure part set at the fixed part, and the other end of the fourth light-transmitting structure part can be hidden to set other devices, which is more helpful to improve the smoothness and aesthetics of the vehicle body structure when the vehicle is equipped with a phased array antenna.

[0132] In some embodiments, the vehicle is also provided with a TBOX located at the other end of the fourth light-transmitting structure portion of the fixed part, and the antenna end includes a transmitting array surface and a receiving array surface. The transmitting array surface is arranged on the side of the antenna end away from the TBOX, and the receiving array surface is arranged on the side of the antenna end close to the TBOX.

[0133] Among them, continue to refer to Figure 6As shown, the first light-transmitting structure portion may further include a movable portion 122. The light transmittance of the movable portion 122 is higher than a third preset light transmittance threshold.

[0134] The second preset light transmittance threshold and the third preset light transmittance threshold may be the same or different.

[0135] When the second preset transmittance threshold is the same as the third preset transmittance threshold, the transmittance of the movable portion 122 and the transmittance of the third transparent structure portion 113 of the fixed portion 121 can be set to be the same to achieve an overall consistent light perspective effect.

[0136] In other examples, when the second preset transmittance threshold is the same as or different from the third preset transmittance threshold, the transmittance of the movable portion 122 and the transmittance of the third light-transmitting structure portion 113 of the fixed portion 121 can also be set to be different, as long as the transmittance of the movable portion 122 and the transmittance of the third light-transmitting structure portion 113 are both higher than the transmittance of the fourth light-transmitting structure portion 114 of the fixed portion 121, so as to achieve differentiated and personalized transmittance settings and effects.

[0137] As described above, the first light-transmitting structure portion having a transmittance greater than the first preset light-transmitting threshold may include the above-mentioned movable portion 122 and the third light-transmitting structure portion 113 of the fixed portion, and the second light-transmitting structure portion 112 having a transmittance less than the first preset light-transmitting threshold includes the fourth light-transmitting structure portion 114. At this time, the first preset light-transmitting threshold includes the above-mentioned second preset light-transmitting threshold and the third preset light-transmitting threshold.

[0138] It is understood that in the relevant embodiments of the present application, the first light-transmitting structural portion, the third light-transmitting structural portion, or the movable portion of the roof light-transmitting structure may include multiple different parts, each of which may be arranged in a certain pattern, and each of which may have a different light transmittance, thereby achieving a personalized and differentiated light transmission effect. In other embodiments, the light transmittance of the first light-transmitting structural portion, the third light-transmitting structural portion, and the movable portion of the roof light-transmitting structure may all be set to the same, thereby achieving a consistent, integrated light transmission effect.

[0139] The location of the antenna end on the roof light-transmitting structure can be set according to technical requirements. The following examples illustrate this.

[0140] In some examples, reference Figure 8 As shown, the roof light-transmitting structure includes a first light-transmitting structure 131 and a second light-transmitting structure 132 that are stacked. The first light-transmitting structure 131 is arranged on the side of the vehicle away from the interior space of the vehicle, and the antenna end 201 is arranged between the first light-transmitting structure 131 and the second light-transmitting structure 132.

[0141] The vehicle-mounted phased array antenna based on this embodiment is configured such that the roof light-transmitting structure includes a first light-transmitting structure and a second light-transmitting structure that are stacked, and the antenna end is disposed between the first light-transmitting structure and the second light-transmitting structure. The first light-transmitting structure and the second light-transmitting structure of the roof light-transmitting structure are usually sealed, thereby helping to improve the sealing performance of the antenna end, and to a certain extent reducing the problems of rain erosion and dust accumulation caused by long-term exposure of the antenna end to the air, and helping to improve the stability of signal reception at the antenna end.

[0142] In some examples, reference Figure 1 As shown, the antenna end 201 is disposed on a side of the roof light-transmitting structure 10 close to the vehicle interior space. That is, the antenna end 201 can be disposed below the roof light-transmitting structure 10, adjacent to the vehicle interior space.

[0143] Based on this embodiment, by arranging the antenna end on the side of the roof light-transmitting structure close to the interior space of the vehicle, it is more conducive to the installation and arrangement of the antenna end, and is more convenient to install the antenna end relative to the roof transparent structure.

[0144] The antenna end 201 may include a first antenna unit layer and a phase modulation chip. In a specific example, the first antenna unit layer and the phase modulation chip may be arranged on a side of the roof light-transmitting structure 10 close to the interior space of the vehicle.

[0145] The antenna unit layer is the unit in the vehicle-mounted phased array antenna used to send and receive signals. By controlling the phase and amplitude of the transmitted and received signals of the antenna unit layer, an adjustable beam direction and shape can be formed.

[0146] The phase modulation chip is a chip used to adjust the phase and amplitude of the antenna unit layer. In the embodiment of the present application, the antenna unit layer arranged adjacent to the phase modulation chip is referred to as the first antenna unit layer.

[0147] In some embodiments, the antenna unit layer may include an antenna unit layer of a transmitting array surface and an antenna unit layer of a receiving array surface, wherein the antenna unit layer of the transmitting array surface and the antenna unit layer of the receiving array surface can be set separately, and when the transmitting array surface and the receiving array surface share the same aperture through a stacked setting, the antenna unit layer of the transmitting array surface and the antenna unit layer of the receiving array surface can also be coaxially distributed.

[0148] Based on this embodiment, by arranging the first antenna unit layer and the phase-modulating chip of the antenna end on the side of the roof light-transmitting structure close to the interior space of the vehicle, it is more conducive to the installation of the first antenna unit layer and the phase-modulating chip, and is conducive to the convenience of installing the antenna end and the roof transparent structure. By laminating the first antenna unit layer and the phase-modulating chip, the demand for the structural design of the phase-modulating chip can be reduced. For example, there is no need to set up special dielectric materials and other structures, which further reduces the thickness of the antenna end structure and is more conducive to the convenience of setting and installing the antenna end.

[0149] In some examples, the antenna end further includes a second antenna unit layer, which is disposed on a side of the first antenna unit layer away from the interior space of the vehicle.

[0150] In the embodiment of the present application, the antenna unit layer that is different from the first antenna unit layer and far away from the interior space of the vehicle is called the second antenna unit layer. That is, when observed from the side of the vehicle, the second antenna unit layer is located above the first antenna unit layer.

[0151] When the first antenna unit layer and the second antenna unit layer are set at the same time, the antenna units of the first antenna unit layer can transmit and receive signals at a certain operating frequency, and the second antenna unit layer can also transmit and receive signals at a certain operating frequency, so that the first antenna unit layer and the second antenna unit layer can be configured to adapt to different communication scenarios and improve signal coverage and anti-interference capabilities.

[0152] Based on this embodiment, a second antenna unit layer is provided on the side of the first antenna unit layer away from the interior space of the vehicle. By adding the second antenna unit layer, the signal loss caused by the signal shielding of the first antenna unit layer by the light-transmitting structure of the roof can be supplemented, which helps to ensure the communication performance of the antenna end.

[0153] The specific position of the second antenna unit layer can be set in combination with actual technical needs. Figure 9 As shown, the roof light-transmitting structure includes a first light-transmitting structure 131 and a second light-transmitting structure 132, which are stacked. The first light-transmitting structure 131 is disposed on a side of the vehicle away from the vehicle interior, and the second antenna unit layer 212 is disposed between the first light-transmitting structure 131 and the second light-transmitting structure 132. The first antenna unit layer 211 is disposed on a side of the second light-transmitting structure 132 adjacent to the vehicle interior, that is, below the second light-transmitting structure 132.

[0154] Based on this embodiment, by setting the roof light-transmitting structure to include a first layer of light-transmitting structure and a second layer of light-transmitting structure arranged in a stacked manner, and setting the second antenna unit layer between the first layer of light-transmitting structure and the second layer of light-transmitting structure, the problems of rain erosion and dust accumulation caused by long-term exposure of the second antenna unit layer to the air can be reduced, which helps to improve the stability and strength of signal reception at the antenna end.

[0155] The specific position of the second antenna unit layer 212 between the first light-transmitting structure 131 and the second light-transmitting structure 132 is not limited. In the relevant embodiment of the present application, the second antenna unit layer 211 is arranged on the side of the first light-transmitting structure 131 adjacent to the second light-transmitting structure 132. Figure 9 As shown, the second antenna unit layer 211 is disposed on one side below the first light-transmitting structure 131 .

[0156] Based on this embodiment, by arranging the second antenna unit layer at the antenna end on the side of the first light-transmitting structure adjacent to the second light-transmitting structure, the rain erosion and dust accumulation problems caused by the long-term exposure of the second antenna unit layer to the air can be reduced, while the second antenna unit layer is placed closer to the external space of the vehicle, which can help to further improve the stability and strength of the sending and receiving signals at the antenna end, and help to further ensure the communication performance of the antenna end.

[0157] The second antenna unit layer can be disposed below the first light-transmitting structure in various possible ways. In a related embodiment, the second antenna unit layer is printed and disposed on a side of the first light-transmitting structure adjacent to the second light-transmitting structure, for example, by silver plating printing.

[0158] The second antenna unit layer is set on the lower side of the first light-transmitting structure by printing, which has a small size, low cost and simple manufacturing process. The second antenna unit layer can be miniaturized and is also more conducive to the hidden setting of the second antenna unit layer in the first light-transmitting structure.

[0159] It is understandable that both the first and second light-transmitting structures can be provided with corresponding first and second light-transmitting structure portions, and the second antenna unit layer can be printed and provided below the second light-transmitting structure portion with lower transmittance of the first light-transmitting structure, which is more conducive to the concealment of the second antenna unit layer, and thus also facilitates the concealment of the antenna end. Similarly, the first antenna unit layer can be provided below the second light-transmitting structure portion with lower transmittance of the second light-transmitting structure, which is more conducive to the concealment of the first antenna unit layer, and thus also facilitates the concealment of the antenna end.

[0160] Based on this embodiment, by printing and arranging the second antenna unit layer on the side of the first light-transmitting structure adjacent to the second light-transmitting structure, a planar structural design of the second antenna unit layer can be achieved, which can significantly reduce the overall volume and is more conducive to improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0161] The operating frequency of the second antenna unit layer and the operating frequency of the first antenna unit layer can be set based on the needs of the actual scenario. In the relevant embodiment of the present application, the operating frequency of the second antenna unit layer and the operating frequency of the first antenna unit layer can be set to be the same.

[0162] When the operating frequency of the second antenna unit layer is the same as that of the first antenna unit layer, the transmitted signals of the first antenna unit layer and the second antenna unit layer can be superimposed, thereby achieving superposition of the transmitted signals. Furthermore, by planning and setting the distance between the second antenna unit layer and the first antenna unit layer, the peaks and troughs of the transmitted signals of the two antenna units overlap, thereby increasing the energy of the transmitted signal of the first antenna unit layer.

[0163] Among them, since the first antenna unit layer is arranged on the side of the roof light-transmitting structure close to the interior space of the vehicle, when the transmission signal of the first antenna unit layer is emitted outward, the transmission signal needs to pass through the roof light-transmitting structure before being emitted into the air, and the roof light-transmitting structure may cause certain loss of the energy of the transmission signal. However, due to the arrangement of the second antenna unit layer, the operating frequency of the second antenna unit layer is the same as the operating frequency of the first antenna unit layer. Therefore, the transmission signal of the second antenna unit layer can be superimposed with the transmission signal of the first antenna unit layer, so that the transmission signal of the second antenna unit layer can effectively supplement the energy loss of the transmission signal of the first antenna unit layer, so that the energy of the transmission signal of the antenna end including the first antenna unit layer and the second antenna unit layer is stable, which helps to maintain and ensure the energy of the transmission signal of the antenna end, and helps to specifically improve the communication performance of the antenna end.

[0164] Based on this embodiment, by setting the communication frequency of the second antenna unit layer to be the same as the communication frequency of the first antenna unit layer, it can be more conducive to making the peaks and troughs of the signal generated by the first antenna unit layer overlap with the peaks and troughs of the signal generated by the second antenna unit layer, and is more conducive to compensating for the signal loss caused by the signal blocking of the first antenna unit layer by the roof light-transmitting structure, which helps to ensure the communication performance of the antenna end.

[0165] Further integration Figure 10As shown, at the position of the roof light-transmitting structure, the phase-modulating chip 213 at the antenna end, the first antenna unit layer 211 at the antenna end, the second light-transmitting structure 132, the second antenna unit layer 212 at the antenna end, and the first light-transmitting structure 131 are arranged in sequence from bottom to top. After the phase-modulating chip 213 adjusts and controls the phases of the first antenna unit layer 211 and the second antenna unit layer 212, the first antenna unit layer 211 and the second antenna unit layer 212 transmit signals according to the adjusted phases. The transmission signal of the first antenna unit layer 211 passes through the second light-transmitting structure 132, is superimposed with the transmission signal of the second antenna unit layer 212, and is then transmitted into the air through the first light-transmitting structure 131.

[0166] The connection method between the first antenna unit layer 211 and the second antenna unit layer 212 is not limited. For example, the first antenna unit layer 211 and the second antenna unit layer 212 can be connected by a wiring harness to achieve a wired connection between the first antenna unit layer 211 and the second antenna unit layer 212. The wiring harness can pass through the space where the side of the roof light-transmitting structure meets the vehicle body structure to achieve the connection between the first antenna unit layer and the second antenna unit layer, but is not limited to this.

[0167] In a related embodiment of the present application, the second antenna unit layer is communicatively connected to the first antenna unit layer via a feeder line.

[0168] A feeder is a wire that transmits radio frequency signals between a transmitter and receiver, serving as a bridge for signal transmission in wireless communications. The feeder eliminates the need for direct physical connection lines between the first and second antenna units, enabling communication between them. This eliminates the complexity of wiring harnesses, further simplifies antenna installation, and improves process convenience.

[0169] It can be seen that by communicatively connecting the second antenna unit layer with the first antenna unit layer via a feeder line, the installation complexity of the second antenna unit layer is reduced, and the installation convenience of various components at the antenna end, such as the second antenna unit layer, is improved.

[0170] In some embodiments, the antenna end is integrated with the roof light-transmitting structure.

[0171] Through an integrated setting, the mutually independent roof light-transmitting structure and the antenna end of the phased array antenna can be integrated into a whole, thereby achieving the overall coordination of the vehicle's roof structure, helping to further reduce the complexity of installation, and helping to reduce external components, and more conducive to improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0172] The phase controller is not limited to a specific location in the vehicle. In some examples, the phase controller is disposed on a main body structure of the vehicle adjacent to the roof light-transmitting structure.

[0173] The vehicle's main structure refers to the basic structural components of the vehicle. In the embodiments of this application, the phase controller can be specifically installed on the vehicle's body sheet metal adjacent to the roof's light-transmitting structure. Body sheet metal refers to thin metal components on the vehicle's body, including front and rear bumpers, doors, roof, trunk lid, hood, fenders, front and rear side panels, and wheel arches. The production process for body sheet metal primarily involves four steps: sheet metal preparation and cutting, sheet metal bonding, welding, and shaping and smoothing.

[0174] Based on this embodiment, by setting the phase controller that is separated from the antenna end on the main body structure of the vehicle body adjacent to the roof light-transmitting structure, the distance between the phase controller and the antenna end can be better controlled while the phase controller and the antenna end are set separately. In addition, by setting the phase controller on the main body structure of the vehicle body, it is also beneficial to the convenience of setting the phase controller, thereby helping to improve the convenience of setting the phase controller.

[0175] The specific position of the phase controller in the main body structure of the vehicle body is not limited. In some examples, the distance between the phase controller and the roof light-transmitting structure is within a preset range, and the upper limit of the preset range is less than the preset distance.

[0176] The specific setting method of the preset range is not limited, as long as it facilitates the installation of the phased array and meets the communication requirements between the phased array and the antenna. For example, in some embodiments, the preset range includes 20-35 mm. By arranging the phased array within a range of 20-35 mm from the roof light-transmitting structure, the phased array can be placed as close to the main body structure as possible while maintaining the communication performance between the phased array and the antenna. This is more conducive to the stealth setting of the phased array and also helps to improve the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0177] Accordingly, by setting the phase controller at a position within a preset range of the distance from the roof light-transmitting structure, and since the antenna end is set on the roof light-transmitting structure, the distance between the phase controller and the antenna end is controlled based on the control of the distance from the roof light-transmitting structure, which helps to facilitate and improve the efficiency of the phase controller position setting, and can reduce the impact of vibrations caused by the vehicle during driving on the devices set under the roof light-transmitting structure.

[0178] In some specific examples, the phase controller is disposed on a main body structure of the vehicle body adjacent to and below a position of a roof light-transmitting structure where the antenna end is located.

[0179] Based on the vehicle-mounted phased array antenna of this embodiment, by setting the phase controller on the vehicle body main structure adjacent to the roof light-transmitting structure where the antenna end is located, the phase controller can be set as close to the antenna end as possible, which helps to improve the signal transmission performance between the antenna end and the phase controller, and thus helps the communication performance of the vehicle-mounted phased array antenna.

[0180] In a specific example, the phase controller is arranged on the vehicle body main structure adjacent to the first side of the first light-transmitting structure portion, and the first side of the first light-transmitting structure portion is a side away from the second light-transmitting structure portion.

[0181] Accordingly, by setting the phase controller at a position adjacent to the first light-transmitting structure part with relatively high light transmittance in the vehicle-mounted light-transmitting structure, and at a position adjacent to the first side of the first light-transmitting structure part on the main body structure of the vehicle body, and the first side of the first light-transmitting structure part is a side away from the second light-transmitting structure part with relatively low light transmittance, it is not necessary to limit the phase controller to a position adjacent to the antenna end, and the phase controller can be set based on the volume of the vehicle body, which helps to further improve the convenience of determining the setting position of the phase controller.

[0182] Based on the vehicle-mounted phased array antenna of each embodiment described above, a specific example is described in detail below. In this example, refer to Figure 11 As shown, the antenna end and the phase controller of the vehicle-mounted phased array antenna are designed to be separated, wherein the antenna end is integrated with the vehicle's roof light-transmitting structure, the roof light-transmitting structure is a skylight glass, and the phase controller is set on the body sheet metal below the roof light-transmitting structure.

[0183] The antenna end of the vehicle-mounted phased array antenna is located on the right side of the rear black border area of ​​the vehicle's skylight (i.e., the second light-transmitting structure with lower light transmittance) near the rear of the vehicle. The left side of this rear black border area is the TBOX layout area. The antenna end and the TBOX as a whole do not extend beyond this rear black border area, achieving a concealed layout. The antenna end includes a transmitting array and a receiving array. The receiving array is close to the TBOX, while the transmitting array is farther away from the TBOX and closer to the right edge of the vehicle.

[0184] The roof's translucent structure consists of two layers of sandwiched glass: a first and second translucent layer. The antenna end comprises a first antenna unit layer and a second antenna unit layer. The second antenna unit layer, serving as the phased array antenna imaging layer, is printed on the second side of the glass sandwich using silver plating, i.e., on the side of the first translucent layer closest to the vehicle's interior. The first antenna unit layer, serving as the antenna body of the on-board phased array antenna, is affixed, along with the phase-modulation chip, to the bottom of the interior glass, i.e., on the side of the second translucent layer closest to the vehicle's interior.

[0185] The phase controller 202 is separate from the antenna and located on the vehicle's main structure, below the right side of the sunroof glass in the vehicle's forward direction. It is spaced 20-35 mm from the sunroof glass and communicates with the antenna via a feeder. It incorporates phase algorithms and phase control capabilities. The phase controller collects signals forwarded by the antenna's phase-modulation chip 213 and calculates the phase values ​​corresponding to each antenna array element in the first and second antenna element layers. The phase control unit then adjusts the phase of each antenna chip 213 to achieve beam alignment.

[0186] The TBOX is connected to the phase controller, and the collaborative workflow between the vehicle-mounted phased array antenna and the TBOX can be as follows:

[0187] After the vehicle is powered on, the antenna end of the onboard phased array antenna receives satellite signals and transmits the signal strength of the received satellite signals to the phase controller via the phase modulation chip 213. The phase calculation module of the phase controller calculates the satellite position based on the received signal strength and outputs the phase adjustment data for each antenna to the phase modulation chip 213 via the phase control module. The phase modulation chip 213 adjusts the phase of each antenna to change the antenna's radiation direction, ensuring the strongest radiation direction facing the satellite. Finally, the phase controller 202 outputs the latest satellite signal, which is transmitted via a feeder to the satellite communication module of the TBOX, enabling data reception and transmission.

[0188] Based on the vehicle-mounted phased array antennas of the various embodiments described above, an embodiment of the present application further provides a vehicle, wherein the vehicle includes a main body structure and a roof light-transmitting structure, wherein the vehicle is further provided with the vehicle-mounted phased array antenna described in any of the embodiments described above.

[0189] Based on the vehicle of this embodiment, by deploying a vehicle-mounted phased array antenna with a separate antenna end and phase controller on the vehicle, and setting the antenna end on the vehicle's roof light-transmitting structure, and setting the phase controller at other locations on the vehicle, the smaller antenna end can be set together with the roof light-transmitting structure, and there is no need to set both the antenna end and the phase controller of the phased array antenna on the roof, avoiding the need for the phased array antenna to protrude from the roof, and improving the smoothness and aesthetics of the vehicle body structure when the phased array antenna is deployed.

[0190] Among them, based on the vehicle of this embodiment, the antenna end and the phaser of the vehicle-mounted phased array antenna are designed to be separated, so that the appearance of the vehicle does not need to be changed and the appearance of the vehicle is not affected. It also avoids the problem that the existing phased array antenna cannot be installed in the car due to its large size. When it is installed on the roof like a luggage rack, it affects the field of view of the user inside the car looking out through the roof glass. Moreover, by integrating the antenna end into the skylight glass, the metal bracket and shell and other supporting structures of the existing phased array antenna can be eliminated. When it is integrated with the roof glass, the first antenna unit layer can be bonded to the phase adjustment chip, and there is no need to set a special dielectric material layer. It can also reduce antenna consumables to achieve cost savings and reduce weight. Among them, the frequency band of the vehicle-mounted phased array antenna can be Ka band. The frequency range of Ka band is 26.5~40GHz. The frequency band is relatively wide, which enables the vehicle to achieve Ka band high-speed satellite communication capabilities, so that the vehicle can enjoy high-speed satellite communication services anytime and anywhere outdoors.
