Description

Technical Field

[0001] This utility model relates to the field of dual-polarized probe antennas, and more particularly to a wideband matching adjustment component for a dual-polarized probe antenna. Background Technology

[0002] A dual-polarized probe antenna is a high-performance antenna capable of simultaneously receiving and transmitting two mutually orthogonal polarized signals. Through unique designs, such as slotted lines and cross-shaped connections, it achieves excellent matching performance over a wide bandwidth. This type of antenna has wide applications in wireless communication systems, significantly improving signal transmission efficiency and stability.

[0003] Dual-polarized probe antennas have a fixed angle and typically use a cross-connection method to integrate two mutually perpendicular polarization units to achieve dual-polarization characteristics. During installation, precise adjustment and fixing of the antenna's orientation ensures optimal radiation performance in a specific direction.

[0004] In existing technologies, some antennas cannot be adjusted in real time according to actual needs after installation, and the angle adjustment area is limited, resulting in the antenna's radiation direction not effectively covering the target area. For applications requiring omnidirectional coverage, such as certain indoor wireless coverage systems or some special outdoor communication scenarios, the difficulty in angle adjustment can severely limit system performance. To address this issue, a wideband matching adjustment component for dual-polarized probe antennas is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wideband matching adjustment component for a dual-polarized probe antenna, aiming to improve the problem in the prior art that some antennas cannot adjust their angle in real time, requiring reinstallation when adjusting the angle, making it difficult to achieve full coverage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wideband matching adjustment assembly for a dual-polarized probe antenna includes a positioning plate. A driving assembly for adjusting the driving angle is fixedly connected to the inner wall of the positioning plate. Two slide rails are formed on the inner wall of the positioning plate, and a sliding shaft is slidably connected to the inner walls of the two slide rails. The driving assembly is rotatably connected to the outside of the sliding shafts. Two rotating rods are rotatably connected to the outside of the sliding shafts. A rotating shaft is rotatably connected to the adjacent side of the two rotating rods. An inclined plate is rotatably connected to the top of the positioning plate, and the other end of the inclined plate is rotatably connected to the outside of the rotating shaft. A connecting block is fixedly connected to the outside of the inclined plate, and an antenna body is mounted on the outside of the connecting block.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a cylinder, the cylinder is externally mounted on the inner wall of the positioning plate, and a moving block is fixedly connected to the drive end of the cylinder.

[0010] As a further description of the above technical solution:

[0011] The bottom of the moving block is slidably connected to the inner wall of the positioning plate, and the other end of the moving block is rotatably connected to the outside of the sliding shaft.

[0012] As a further description of the above technical solution:

[0013] The bottom of the positioning plate is rotatably connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to multiple movable columns.

[0014] As a further description of the above technical solution:

[0015] Each of the movable columns has a movable ball movably connected to its bottom, and each of the movable balls has a spring fixedly connected to its inner wall.

[0016] As a further description of the above technical solution:

[0017] The movable columns are externally connected to a fixed box, and the other end of the multiple springs is fixedly connected to the inner wall of the fixed box.

[0018] As a further description of the above technical solution:

[0019] The two movable columns are slidably connected to the outside by sliding blocks, and the inner walls of the two sliding blocks are movably connected to horizontal rods.

[0020] As a further description of the above technical solution:

[0021] A horizontal ball is rotatably connected to the inner wall of the fixed box, and the outer side of the horizontal ball is rotatably connected to the bottom of the horizontal rod.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the position change of the tilting plate causes the position of the connecting block to change, and the position change of the connecting block causes the antenna body to change its angle. The antenna angle can be adjusted without changing the installation position. Furthermore, the elevation angle can be changed by rotating the positioning plate, which can better adapt to different environments and needs and ensure that the radiation direction is accurately aligned with the target area.

[0024] 2. In this utility model, the horizontal rod drives the two sliding blocks to be horizontal, and the two sliding blocks drive the two movable columns to be stable, thereby restoring the bottom of the device to be horizontal. This can effectively absorb the vibration of the external environment or the equipment itself, prevent these vibrations from being transmitted to the antenna body, and thus avoid adverse effects on the antenna pattern and performance.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of a wideband matching adjustment component for a dual-polarized probe antenna, including a positioning plate 1. A driving component for adjusting the driving angle is fixedly connected to the inner wall of the positioning plate 1. The positioning plate 1 supports and fixes the position of the driving component. The driving component includes a cylinder 2, which is externally mounted on the inner wall of the positioning plate 1. The positioning plate 1 fixes the position of the cylinder 2, ensuring that one end of the cylinder 2 remains fixed during driving. A moving block 3 (as shown in the attached figure) is fixedly connected to the driving end of the cylinder 2. Figure 3 When cylinder 2 is activated, the position of cylinder 2 changes, causing the position of moving block 3 to change as well.

[0034] The bottom of the movable block 3 is slidably connected to the inner wall of the positioning plate 1. The inner wall of the positioning plate 1 is horizontal, and the bottom of the movable block 3 is smooth, so the movable block 3 can move freely on the inner wall of the positioning plate 1. Two slide rails are provided on the inner wall of the positioning plate 1, and the inner walls of the two slide rails are slidably connected to the sliding shaft 4. The slide rails provided on the positioning plate 1 reduce friction on the sliding shaft 4 during the sliding process and make the sliding smoother, and limit the sliding trajectory to a certain extent.

[0035] Reference Figure 3 The other end of the moving block 3 is rotatably connected to the outside of the sliding shaft 4. Changes in the position of the moving block 3 cause the sliding shaft 4 to slide. The external drive assembly is rotatably connected to the outside of the sliding shaft 4, causing changes in the position of the sliding shaft 4. Two rotating rods 5 are rotatably connected to the outside of the sliding shaft 4. The sliding of the sliding shaft 4 causes the two rotating rods 5 to rotate. A rotating shaft 6 is rotatably connected to the adjacent side of the two rotating rods 5. Changes in the position of one end of the two rotating rods 5 cause changes in the position of the rotating shaft 6. An inclined plate 7 is rotatably connected to the top of the positioning plate 1. The positioning plate 1 has a function of fixing the rotational position of one end of the inclined plate 7, so that when the position of the other end of the inclined plate 7 changes, one end can move along with it without detaching from the device.

[0036] The other end of the tilting plate 7 is rotatably connected to the outside of the rotating shaft 6. Changes in the position of the rotating shaft 6 cause changes in the position of the tilting plate 7. A connecting block 8 is fixedly connected to the outside of the tilting plate 7. Changes in the angle of the tilting plate 7 cause changes in the angle of the connecting block 8. An antenna body 9 is mounted on the outside of the connecting block 8. Changes in the angle of the connecting block 8 cause changes in the angle of the antenna body 9. The connecting block 8 connects the antenna body 9 to the angle adjustment assembly; it is external to the antenna body 9 and does not affect its performance.

[0037] Reference Figures 3 to 5A connecting plate 10 is rotatably connected to the bottom of the positioning plate 1. Shaking of the positioning plate 1 causes the connecting plate 10 to shake. Multiple movable columns 12 are fixedly connected to the bottom of the connecting plate 10. Shaking of the connecting plate 10 causes the positions of the multiple movable columns 12 to shake. Movable balls 13 are movably connected to the bottom of each of the multiple movable columns 12. Shaking of the movable columns 12 causes the movable balls 13 to shake. Springs 14 (as shown in the attached diagram) are fixedly connected to the inner walls of each of the multiple movable balls 13. Figure 5 The shaking of the movable ball 13 causes the spring 14 to deform, and the spring 14 is used to absorb external forces. The multiple movable columns 12 are externally connected to a fixed box 11, which is installed on the ground and is used to adjust the position of the multiple movable columns 12. The movable connection means that the position of the movable column 12 shifts during the shaking process but does not move in a directional manner.

[0038] The other ends of multiple springs 14 are fixedly connected to the inner wall of the fixed box 11. The fixed box 11 fixes the position of the other end of the springs 14 and fixes one end of the springs 14 when they absorb external force. Sliding blocks 15 are slidably connected to the outside of two movable columns 12. The sliding blocks 15 limit the relative position of the two movable columns 12 when their positions change, because the outside of the sliding blocks 15 fits against the two movable columns 12, so that the outside of the movable columns 12 is exactly within the groove of the sliding blocks 15. A horizontal rod 16 is movably connected to the inner wall of the two sliding blocks 15. The horizontal rod 16 keeps the two sliding blocks 15 horizontal, and its horizontal position keeps both ends horizontal. A horizontal ball 17 is rotatably connected to the inner wall of the fixed box 11, and the fixed box 11 fixes the position of the horizontal ball 17. The outside of the horizontal ball 17 is rotatably connected to the bottom of the horizontal rod 16. After the external force disappears, the stability of the horizontal ball 17 stabilizes the horizontal rod 16.

[0039] Working principle: The cylinder 2 is activated. The position change of the driving end of the cylinder 2 causes the moving block 3 to change position. The position change of the moving block 3 causes the sliding shaft 4 to slide. The sliding of the sliding shaft 4 causes the two rotating rods 5 to rotate, thereby pushing the rotating shaft 6 at the other end to rotate and change position. The position change of the rotating shaft 6 causes one end of the tilting plate 7 to change position, and the other end of the tilting plate 7 to rotate. The position change of the tilting plate 7 causes the connecting block 8 to change position, and the position change of the connecting block 8 causes the antenna body 9 to change angle. By rotating the positioning plate 1, the elevation angle of the antenna body 9 can be changed. By adjusting the angle of the antenna, it can better adapt to different environments and needs, ensuring that the radiation direction is accurately aligned with the target area, thereby enhancing signal strength, reducing interference, and improving communication quality and system performance.

[0040] When there is external vibration, the position of the antenna body 9 changes, causing the position of the positioning plate 1 to shake, which in turn causes the connecting plate 10 to shake. The shaking of the connecting plate 10 causes multiple movable columns 12 to shake, which in turn causes multiple movable balls 13 to shake. The shaking of the movable balls 13 causes multiple springs 14 to deform. The deformation of the springs 14 is used to absorb vibration. After the external force disappears, the horizontal ball 17 becomes horizontal, which in turn causes the horizontal rod 16 to become horizontal. The horizontal rod 16 becomes horizontal, which in turn causes the two sliding blocks 15 to become horizontal. The two sliding blocks 15 respectively stabilize the positions of the two movable columns 12, thereby restoring the bottom of the device to a horizontal position. This effectively absorbs vibrations from the external environment or the device itself, preventing these vibrations from being transmitted to the antenna body 9, thus avoiding adverse effects on the antenna pattern and performance, and helping to maintain the directivity and gain stability of the antenna.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
