[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be 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 the present application and are not used to limit the present application.

[0028] It should be noted that the terms "first", "second", etc. in the specification, claims and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0030] In the field of mobile communication network technology, the Luneburg lens antenna has been widely promoted and applied due to its unique design and performance advantages. However, the traditional lens antenna has certain limitations in adjusting the radiation direction of the feed source. Specifically, the radiation direction of the feed source of the traditional lens antenna can only be adjusted up and down, and cannot be adjusted left and right in the horizontal direction, resulting in obvious deficiencies in the coverage range of the traditional lens antenna, especially in application scenarios that require extensive coverage of linear areas, such as signal coverage of railways or highways.

[0031] Railways and highways are usually linearly distributed, requiring the antenna to be able to flexibly adjust the radiation direction in the horizontal direction to ensure that the signal can evenly cover the entire line. However, due to the inability to achieve horizontal direction adjustment, the application effect of the traditional lens antenna in these scenarios is not good. Specifically, the signal coverage is uneven, there are blind areas or weak signal areas, thus affecting the communication quality and user experience.

[0032] Based on this, the embodiments of the present invention provide a lens antenna, enabling the feed source to be adjusted left and right in the horizontal direction to ensure that the signal can accurately cover the target area.

[0033] The following will further elaborate on the embodiments of the present invention with reference to the accompanying drawings.

[0034] Refer to Figures 1 to 4 , the embodiments of the present invention application propose a lens antenna, including: a mounting plate assembly 100, a transmission mechanism, a first reflector assembly 300, and a first Luneburg lens 410;

[0035] The mounting plate assembly 100 includes: a mounting plate 110 and an end plate 120 located on the side of the mounting plate 110;

[0036] The transmission mechanism is arranged on the mounting plate 110. The transmission mechanism includes: a first guide rail 210, a second guide rail 220, a motor 230, a screw assembly 240, a guide post 250, and an adapter 260. The first guide rail 210 and the second guide rail 220 are both arranged parallel to the end plate 120. The screw assembly 240 is respectively connected to the motor 230 and the guide post 250. The adapter 260 is sleeved above the guide post 250, and the adapter 260 is connected to the second guide rail 220 through a sliding member 270;

[0037] The first reflector assembly 300 includes: a reflector 310 and a plurality of feeds 320. One end of the reflector 310 is connected to the adapter 260, and the other end of the reflector 310 is connected to the first guide rail 210 through a sliding member 270. The plurality of feeds 320 are respectively arranged on a plurality of mounting surfaces 311 on the reflector 310, and the included angles between adjacent mounting surfaces 311 are equal;

[0038] The first Luneburg lens 410 is arranged on the reflector 310, and the distance from each feed 320 to the center of the first Luneburg lens 410 is equal;

[0039] Wherein, when the motor 230 drives the screw assembly 240, the guide post 250 pushes the reflector 310 assembly to move along an arc-shaped trajectory.

[0040] According to a lens antenna provided by an embodiment of the present invention, the first guide rail 210 and the second guide rail 220 are both arranged parallel to the end plate 120, ensuring that the arc-shaped trajectory pre-designed in the first guide rail 210 and the second guide rail 220 can enable the reflector 310 assembly to be adjusted left and right in the horizontal direction. Further, the transmission structure uses the motor 230 to drive the screw assembly 240. The screw assembly 240 is connected to the guide post 250. The adapter 260 sleeved on the guide post 250 is connected to the second guide rail 220 through a sliding member 270. One end of the reflector 310 is connected to the adapter 260, and the other end of the reflector 310 is connected to the first guide rail 210 through a sliding member 270. When the motor 230 drives the screw assembly 240, the guide post 250 is pushed by the screw assembly 240, and then drives the first reflector assembly 300 connected to the adapter 260 to move along the arc-shaped trajectory pre-designed in the first guide rail 210 and the second guide rail 220, realizing the left or right adjustment of the lens antenna in the horizontal direction, ensuring that the signal can accurately cover the target area, significantly improving the applicability of the antenna in linear scenarios such as railways and highways, and effectively solving the problem of uneven signal coverage.

[0041] It should be noted that the first guide rail 210 and the second guide rail 220 are spaced apart by a certain distance. The structure of the reflector 310 is approximately a semicircle, and a plurality of feeders 320 are arranged in an arc around the center of the first Luneburg lens 410, ensuring that the distance from each feeder 320 to the center of the first Luneburg lens 410 is equal. The feeder 320 provides radiated electromagnetic waves to achieve multiple high-gain beams.

[0042] It should be noted that it further includes an end plate support 140 and a connector 130. A plurality of connectors 130 are arranged in the end plate 120. One end of the end plate support 140 is connected to the mounting plate 110, and the other end of the end plate support 140 is connected to the end plate 120. The end plate support 140 is used to support the end plate 120 and the connector 130.

[0043] It can be understood that the lens antenna provided in this embodiment adopts a modular and miniaturized design, which is convenient to assemble and can effectively reduce production costs.

[0044] In some embodiments, it further includes a main control module and a communication module. The main control module is respectively connected to the motor 230 and the communication module. When the lens antenna needs to be adjusted in the horizontal direction, the user can remotely control it through the communication module, so that the main control module controls the motor 230 to work according to the actual signal coverage requirements. Further, the motor 230 drives the screw assembly 240. The screw assembly 240 is connected to the guide post 250. The adapter 260 sleeved on the guide post 250 is connected to the second guide rail 220 through a slider 270. One end of the reflector 310 is connected to the adapter 260, and the other end of the reflector 310 is connected to the first guide rail 210 through a slider 270. When the motor 230 drives the screw assembly 240, the guide post 250 is pushed by the screw assembly 240, and then drives the first reflector assembly 300 connected to the adapter 260 to move along the pre-designed circular arc trajectory in the first guide rail 210 and the second guide rail 220, dynamically adjusting the horizontal angle of the feeder 320 to ensure that the signal can accurately cover the target area, significantly improving the applicability of the antenna in linear scenarios such as railways and highways, and effectively solving the problem of uneven signal coverage. Moreover, there is no need for maintenance workers to climb to the top of the tower for on-site adjustment, greatly reducing the construction difficulty and saving a large amount of adjustment time. In addition, the adjustment by controlling the motor 230 is more accurate than manual adjustment, improving the operating stability of the lens antenna.

[0045] In some embodiments, arc-shaped long holes are provided on both the first guide rail 210 and the second guide rail 220. The adapter 260 is connected to the arc-shaped long hole of the second guide rail 220 through a slider 270, and the other end of the reflector 310 is connected to the arc-shaped long hole of the first guide rail 210 through two sliders 270. Moreover, the height of the first guide rail 210 is higher than the height of the second guide rail 220.

[0046] It can be understood that the adapter 260 is connected to the arc-shaped long hole of the second guide rail 220 through a slider 270, and the other end of the reflector 310 is connected to the arc-shaped long hole of the first guide rail 210 through two sliders 270. The three sliders 270 form a triangle in space, enhancing the stability of the reflector 310 assembly.

[0047] It can be understood that the adapter 260 is connected to the second guide rail 220 through the slider 270. The adapter 260 itself has a certain height. The height of the first guide rail 210 is designed to be higher than that of the second guide rail 220, and the adapter 260 is arranged above the second guide rail 220 to ensure that the reflector 310 in the first reflector assembly 300 can be kept stable when installed above the adapter 260 and the first guide rail 210, which is beneficial for the subsequent horizontal left-right adjustment of the feed 320 and improves the stability of the antenna operation.

[0048] Preferably, the slider 270 includes a cross bar, a first fastener, and a second fastener. One end of the cross bar passes through one side of the arc-shaped long hole in the first guide rail 210 and is connected to the first fastener, and the other end of the cross bar passes through the reflector 310 and is then connected to the second fastener, ensuring that the slider 270 can slide smoothly in the arc-shaped long hole of the first guide rail 210.

[0049] Preferably, the slider 270 includes a cross bar, a first fastener, and a second fastener. One end of the cross bar passes through one side of the arc-shaped long hole in the second guide rail 220 and is connected to the first fastener, and the other end of the cross bar passes through the adapter 260 and is then connected to the second fastener, ensuring that the slider 270 can slide smoothly in the arc-shaped long hole of the second guide rail 220.

[0050] In some embodiments, referring to Figure 1 , a gasket 800 is provided between the first guide rail 210 and the other end of the reflector 310.

[0051] It can be understood that the gasket 800 can play a buffering role during sliding, avoiding direct contact between the first guide rail 210 and the reflector 310 during sliding, increasing the resistance and causing transmission jamming, and ensuring that the slider 270 can slide smoothly in the arc-shaped long hole of the second guide rail 220.

[0052] Preferably, the slider 270 includes a cross bar, a first fastener, and a second fastener. One end of the cross bar passes through one side of the arc-shaped long hole in the first guide rail 210 and is connected to the first fastener, and the other end of the cross bar passes through the gasket 800 and the reflector 310 and is then connected to the second fastener, ensuring that the slider 270 can slide smoothly in the arc-shaped long hole of the first guide rail 210.

[0053] In some embodiments, referring to Figure 1, further comprising a connecting seat 500, the connecting seat 500 is connected to the screw assembly 240, and the guide post 250 is disposed above the connecting seat 500.

[0054] It can be understood that when the motor 230 drives the screw assembly 240, the screw assembly 240 drives the connecting seat 500 to move, thereby pushing the guide post 250, and the guide post 250 further drives the first reflector assembly 300 connected to the adapter 260 to move along the pre-designed circular arc trajectory in the first guide rail 210 and the second guide rail 220, realizing the angular adjustment of the lens antenna in the horizontal direction.

[0055] It should be noted that an installation hole is provided in the guide post 250, and the installation hole is fixedly connected to the connecting seat 500 provided on the screw assembly 240 by screws.

[0056] In some embodiments, referring to Figure 2 , Figure 4 , further comprising: a second reflector assembly 600, a second Luneburg lens 420. The size and structure of the second reflector assembly 600 are the same as those of the first reflector assembly 300. The transmission mechanism further includes a third guide rail 280 and a fourth guide rail 290. Both the third guide rail 280 and the fourth guide rail 290 are arranged in parallel with the end plate 120. The adapter 260 is connected to the third guide rail 280 through a slider 270. One end of the reflector 310 in the second reflector assembly 600 is connected to the adapter 260, and the other end of the reflector 310 in the second reflector assembly 600 is connected to the fourth guide rail 290 through a slider 270. The second Luneburg lens 420 is disposed on the reflector 310 in the second reflector assembly 600, and the distance from the feed 320 in each second reflector assembly 600 to the center of the second Luneburg lens 420 is equal. Wherein, when the motor 230 drives the screw assembly 240, the guide post 250 pushes the first reflector assembly 300 and the second reflector assembly 600 to move along the circular arc trajectory.

[0057] It should be noted that the third guide rail 280 and the fourth guide rail 290 are spaced apart by a certain distance, and the first guide rail 210, the second guide rail 220, the third guide rail 280, and the fourth guide rail 290 are arranged in sequence above the mounting plate 110.

[0058] It should be noted that the adapter 260 can carry the first reflector assembly 300, the first Luneburg lens 410 above the first reflector assembly 300, the second reflector assembly 600, and the second Luneburg lens 420 above the second reflector assembly 600 at the same time. When the motor 230 drives the screw assembly 240, the screw assembly 240 pushes the guide post 250 through the connecting seat 500. While the guide post 250 drives the first reflector assembly 300 connected to the adapter 260 to move along the pre-designed circular arc trajectory in the first guide rail 210 and the second guide rail 220, it also drives the second reflector assembly 600 connected to the adapter 260 to move along the pre-designed circular arc trajectory in the third guide rail 280 and the fourth guide rail 290, so as to realize the synchronous angular adjustment of the feed 320 above the first reflector assembly 300 and the feed 320 above the second reflector assembly 600 in the horizontal direction.

[0059] It can be understood that, on the one hand, the cooperative work of the first Luneburg lens 410 and the second Luneburg lens 420 can achieve a wider signal coverage range. Specifically, by superimposing the radiation signals to enhance the signal intensity in the target area, the communication quality can be effectively improved; on the other hand, compared with the solution of setting one Luneburg lens on one mounting plate 110, integrating two Luneburg lenses on the same mounting plate 110 can reduce the installation space and production cost.

[0060] It can be understood that, compared with the solution in which each reflector 310 assembly needs to be equipped with an independent driving device, such as the driving device composed of the motor 230 and the screw assembly 240, to realize the left-right adjustment of the feed 320 in the horizontal direction, by adding the adapter 260 and the guide post 250 to coordinate the motor 230 and the screw assembly 240, only one motor 230 and one screw assembly 240 are needed to synchronously realize the left-right adjustment of at least two reflector 310 assemblies in the horizontal direction. On the one hand, the number of motors 230 and screw assemblies 240 used is reduced, significantly reducing the hardware cost and maintenance cost; on the other hand, the overall structure can be made more compact and concise, and the assembly difficulty is reduced.

[0061] In some embodiments, arc-shaped long holes are provided on both the third guide rail 280 and the fourth guide rail 290. The adapter 260 is connected to the arc-shaped long hole of the third guide rail 280 through a sliding member 270, and the other end of the reflector 310 in the second reflector assembly 600 is connected to the arc-shaped long hole of the fourth guide rail 290 through two sliding members 270. Moreover, the height of the third guide rail 280 is lower than the height of the fourth guide rail 290.

[0062] It can be understood that the adapter 260 is connected to the arc-shaped long hole of the third guide rail 280 through a sliding member 270, and the other end of the reflector 310 in the second reflector assembly 600 is connected to the arc-shaped long hole of the fourth guide rail 290 through two sliding members 270. The three sliding members 270 form a triangle in space, which enhances the stability of the reflector 310 assembly.

[0063] It can be understood that the adapter 260 is connected to the third guide rail 280 through the sliding member 270, and the adapter 260 itself has a certain height. The height of the third guide rail 280 is designed to be lower than the height of the fourth guide rail 290, and the adapter 260 is arranged above the third guide rail 280 to ensure that the reflector 310 in the second reflector assembly 600 is installed above the adapter 260 and the first guide rail 210 to remain stable, which is beneficial to the subsequent left and right adjustment of the feed source 320 in the horizontal direction, thereby improving the stability of the antenna operation.

[0064] In some embodiments, the size and structure of the third guide rail 280 are the same as those of the second guide rail 220 , the size and structure of the fourth guide rail 290 are the same as those of the first guide rail 210 , and the motor 230 , the screw assembly 240 , and the guide column 250 are all arranged between the second guide rail 220 and the third guide rail 280 .

[0065] It should be noted that the size structure of the second Luneburg lens 420 is also the same as that of the first Luneburg lens 410, and since the size structure of the third guide rail 280 is the same as that of the second guide rail 220, the size structure of the fourth guide rail 290 is the same as that of the first guide rail 210, and the size structure of the second reflector plate assembly 600 is the same as that of the first reflector plate assembly 300, the first Luneburg lens 410 and the second Luneburg lens 420 can be symmetrically installed on the mounting plate 110, making the weight distribution of the overall structure more uniform, reducing the shaking caused by external vibrations or wind and other factors, thereby improving the anti-interference ability.

[0066] It can be understood that by arranging the motor 230, the screw assembly 240 and the guide post 250 between the second guide rail 220 and the third guide rail 280, space can be utilized more effectively, making the overall structure more compact. In addition, in the process where the motor 230 drives the screw assembly 240 and the guide post 250 pushes the first reflector assembly 300 and the second reflector assembly 600 to move along a circular arc trajectory, the motor 230, the screw assembly 240 and the guide post 250 are all arranged between the second guide rail 220 and the third guide rail 280, which can more effectively transmit force, making the driving force for driving the reflector 310 assembly to move smaller, avoiding excessive torque or stress on the adapter 260 during the adjustment process, and further reducing the wear on the adapter 260.

[0067] In some embodiments, reference Figure 3, the adapter 260 includes a panel 261, a first bending structure 262, and a second bending structure 263. Both the first bending structure 262 and the second bending structure 263 are perpendicularly connected to the panel 261. An oblong hole 264 for mating connection with the guide post 250 is provided in the panel 261. The first bending structure 262 is connected to the second guide rail 220 through a sliding member 270. One end of the reflector 310 in the first reflector assembly 300 is connected to one end of the panel 261. The second bending structure 263 is connected to the third guide rail 280 through a sliding member 270. One end of the reflector 310 in the second reflector assembly 600 is connected to the other end of the panel 261.

[0068] It can be understood that the panel 261 is snap - connected to the guide post 250 through the oblong hole 264, and the oblong hole 264 is located in the middle of the panel 261. An installation hole is provided at one end of the reflector 310 in the first reflector assembly 300 and is connected to the installation hole provided at one end of the panel 261 through a screw; an installation hole is provided at one end of the reflector 310 in the second reflector assembly 600 and is connected to the installation hole provided at the other end of the panel 261 through a screw.

[0069] Preferably, the sliding member 270 includes a cross bar, a first fastener, and a second fastener. One end of the cross bar passes through one side of the arc - shaped long hole in the second guide rail 220 and is connected to the first fastener. The other end of the cross bar passes through the first bending structure 262 and is then connected to the second fastener, ensuring that the sliding member 270 can slide smoothly in the arc - shaped long hole of the second guide rail 220.

[0070] Preferably, the sliding member 270 includes a cross bar, a first fastener, and a second fastener. One end of the cross bar passes through one side of the arc - shaped long hole in the third guide rail 280 and is connected to the first fastener. The other end of the cross bar passes through the second bending structure 263 and is then connected to the second fastener, ensuring that the sliding member 270 can slide smoothly in the arc - shaped long hole of the second guide rail 220.

[0071] In some embodiments, a hollowed - out area is provided on the panel 261, which can effectively reduce the weight of the overall device.

[0072] In some embodiments, the first reflector assembly 300 further includes a plurality of director plates 700. The director plates 700 are arranged above the feed 320 through connecting columns.
