Description

Technical Field

[0001] This invention belongs to the field of antenna structure technology, and specifically relates to an antenna array angle compensation mechanism. Background Technology

[0002] In modern communication systems, the angle of the antenna array has a significant impact on the quality of signal reception and transmission. To protect the antenna array, it is often covered with a radome; however, adjusting the angle of the existing antenna array often requires removing the radome, which is time-consuming, laborious, and compromises the airtightness of the equipment. Summary of the Invention

[0003] In view of this, the present invention discloses an antenna array angle compensation mechanism, the purpose of which is to solve the problem that the existing antenna array angle adjustment requires the removal of the antenna cover.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An antenna array angle compensation mechanism includes an antenna radome, a fixed base and an antenna mounting platform for mounting the antenna are disposed inside the radome, and a plurality of mounting columns are disposed between the fixed base and the radome; a support column is vertically disposed on the top of the fixed base, and a spherical cavity is formed at the top of the support column; the bottom of the antenna mounting platform is fixed to a mounting ball that mates with the spherical cavity; a deflection structure for driving the antenna mounting platform to deflect is disposed on the fixed base.

[0006] In this solution, the antenna mounting platform can be deflected around the mounting sphere by utilizing the cooperation between the mounting sphere and the spherical cavity. The angle of the antenna array can then be adjusted by pushing the antenna mounting platform through the deflection structure. Compared with existing technologies, it eliminates the need to remove the radome, making it simple, quick, convenient, and labor-saving, and the structure is also simple.

[0007] Furthermore, the deflection structure includes an annular bottom bracket, which is coaxially rotatably connected to the top of a fixed base. The fixed base is equipped with a drive device for rotating the bottom bracket, and a locking structure is provided between the fixed base and the bottom bracket. Two vertically arranged linear motors are symmetrically fixed on the bottom bracket, and a fixed support rod is coaxially mounted on the output end of each linear motor. Each fixed support rod is ball-jointed with a slide block. An annular groove is coaxially formed at the bottom of the antenna mounting platform, and an annular frame is coaxially rotatably connected within the annular groove. Two horizontally oriented adjustment rails are symmetrically mounted on the annular frame, and the slide blocks are slidably connected to the adjustment rails.

[0008] In this design, when adjusting the antenna array angle, ensure that the slides are all positioned at the ends of the adjusting guide rails facing the mounting sphere. At this point, the contact locking structure locks the bottom bracket, and the drive device rotates the bottom bracket. The bottom bracket, in turn, drives the adjusting guide rails and the ring frame to rotate synchronously via a linear motor, fixed support rod, and slides until the adjusting guide rails are aligned with the antenna array angle adjustment direction. Then, only one linear motor needs to push the fixed support rod upwards, and the other linear motor needs to push the fixed support rod downwards, thereby pushing the corresponding slides within the adjusting guide rails. This causes the antenna mounting platform to deflect, thus adjusting the antenna array angle. This design allows for precise control of the antenna array angle adjustment direction, resulting in more accurate antenna array angle adjustment.

[0009] Furthermore, the mounting ball has several positioning holes on its periphery facing its center, and the cross-section of the positioning holes is gear-shaped; a first telescopic rod is vertically arranged inside the spherical cavity facing the center of the mounting ball, and the output end of the first telescopic rod is provided with a positioning gear for matching the shape of the positioning holes; several insertion holes are evenly opened in the annular groove, and through holes corresponding to one of the insertion holes are coaxially opened on the adjusting guide rail and the annular frame; a mounting cavity is opened at the top of the slide block, and a telescopic synchronization rod is vertically arranged upward inside the mounting cavity.

[0010] In this design, when the antenna array does not need to rotate, with the slides positioned at the ends of the adjusting guide rails facing the mounting ball, the synchronizing rod remains uninserted into the insertion hole. At this time, the first telescopic rod is controlled to drive the positioning gear into the positioning hole, thereby limiting the deflection of the mounting ball within the spherical cavity and preventing the antenna mounting platform from rotating synchronously with the ring frame, which would cause a change in the antenna array's orientation. When the antenna array's orientation needs to be changed, the first telescopic rod is controlled to drive the positioning gear out of the positioning hole. The synchronizing rod then extends, passing through the through hole and into the insertion hole. Power transmission is then provided by the drive device, causing the antenna mounting platform to rotate synchronously with the ring frame, thus adjusting the antenna array's orientation. Once the antenna array's angle is adjusted to the correct position, the first telescopic rod is controlled to drive the positioning gear into the positioning hole, and the end of the synchronizing rod is controlled to disengage from the insertion hole and through hole.

[0011] Furthermore, the locking structure includes a cavity disposed inside the bottom bracket, a second telescopic rod installed inside the cavity, the output end of the second telescopic rod penetrating downward through the bottom bracket; the upper end of the fixed base is provided with a plurality of locking holes arranged in a circular array, all of which are located below the bottom bracket.

[0012] Furthermore, the bottom of the antenna mounting platform is provided with several annular mounting slots, all of which are coaxial with the annular slots. An annular auxiliary frame is rotatably connected inside the mounting slot, and the auxiliary frame is fixedly connected to the adjusting guide rail.

[0013] Furthermore, an anti-tipping rod is provided between the support column and the fixed base.

[0014] Furthermore, the mounting column, the first telescopic rod, the second telescopic rod, and the synchronizing rod are electrically operated telescopic rods.

[0015] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0023] like Figures 1-5 As shown:

[0024] An antenna array angle compensation mechanism includes an antenna radome 1, a fixed base 2 and an antenna mounting platform 6 for mounting the antenna are disposed inside the antenna radome 1, and a plurality of mounting columns 3 are disposed between the fixed base 2 and the antenna radome 1; a support column 4 is vertically disposed on the top of the fixed base 2, and a spherical cavity is opened at the top of the support column 4; the bottom of the antenna mounting platform 6 is fixed to a mounting ball 5 that mates with the spherical cavity; and a deflection structure is disposed on the fixed base 2 for driving the antenna mounting platform 6 to deflect.

[0025] In this scheme, by utilizing the cooperation between the mounting ball 5 and the spherical cavity, the antenna mounting platform 6 can be deflected around the mounting ball 5 as the center. Then, by using the deflection structure, the antenna mounting platform 6 can be pushed to adjust the angle of the antenna array. Compared with the existing technology, there is no need to remove the antenna cover 1, which is simple, quick, convenient and labor-saving, and the structure is simple.

[0026] In this embodiment, the deflection structure includes an annular bottom bracket 7, which is coaxially rotatably connected to the top of the fixed base 2. The fixed base 2 is provided with a driving device 8 for driving the rotation of the bottom bracket 7 (in this embodiment, a motor drive is used, which is a conventional technical means and therefore not described in detail). A locking structure is provided between the fixed base 2 and the bottom bracket 7. Two vertically arranged linear motors 9 are symmetrically fixed on the bottom bracket 7. The output end of the linear motor 9 is coaxially provided with a fixed support rod 10. Each fixed support rod 10 is ball-jointed to a slide block 11. The bottom of the antenna mounting platform 6 is coaxially provided with an annular groove. An annular frame 12 is coaxially rotatably connected in the annular groove. Two horizontally oriented adjustment guide rails 13 are symmetrically provided on the annular frame 12, and the slide blocks 11 are slidably connected to the adjustment guide rails 13.

[0027] In this design, when the antenna array angle needs to be adjusted, ensure that the slide blocks 11 are all located at the ends of the adjusting guide rail 13 facing the mounting ball 5. At this time, the contact locking structure locks the bottom bracket 7, and the driving device 8 drives the bottom bracket 7 to rotate. The bottom bracket 7 then drives the adjusting guide rail 13 and the ring frame 12 to rotate synchronously through the linear motor 9, the fixed support rod 10, and the slide blocks 11 until the adjusting guide rail 13 faces the antenna array angle adjustment direction. At this point, only one linear motor 9 needs to push the fixed support rod 10 upward, and the other linear motor 9 needs to push the fixed support rod 10 downward, thereby pushing the corresponding slide block 11 to slide within the adjusting guide rail 13, which can drive the antenna mounting platform 6 to deflect, thus adjusting the antenna array angle. This design can precisely control the antenna array angle adjustment direction, thereby adjusting the antenna array angle more accurately.

[0028] In this embodiment, the mounting ball 5 has several positioning holes 14 on its periphery facing its center, and the cross-section of the positioning holes 14 is gear-shaped; a first telescopic rod 15 is vertically arranged in the spherical cavity facing the center of the mounting ball 5, and the output end of the first telescopic rod 15 is provided with a positioning gear 16 for matching the shape of the positioning holes 14; several insertion holes are evenly opened in the annular groove, and through holes corresponding to one of the insertion holes are coaxially opened on the adjusting guide rail 13 and the annular frame 12; a mounting cavity is opened at the top of the slide block 11, and a telescopic synchronous rod 17 is vertically arranged upward in the mounting cavity.

[0029] In this scheme, when the antenna array does not need to rotate, with the slide block 11 positioned at the end of the adjusting guide rail 13 facing the mounting ball 5, the synchronizing rod 17 is kept out of the insertion hole. At this time, the first telescopic rod 15 is controlled to drive the positioning gear 16 into the positioning hole 14, thereby limiting the deflection of the mounting ball 5 within the spherical cavity and preventing the antenna mounting platform 6 from rotating synchronously with the ring frame 12, which would cause a change in the orientation of the antenna array. When the orientation of the antenna array needs to be changed, the first telescopic rod 15 is controlled to drive the positioning gear 16 out of the positioning hole 14. At this time, the synchronizing rod 17 is controlled to extend, allowing it to pass through the through hole and into the insertion hole. Power transmission can then be provided through the drive device 8, thereby driving the antenna mounting platform 6 to rotate synchronously with the ring frame 12, thus adjusting the orientation of the antenna array. After the angle of the antenna array is adjusted to the correct position, the first telescopic rod 15 is controlled to drive the positioning gear 16 into the positioning hole 14, and the end of the synchronizing rod 17 is controlled to disengage from the insertion hole and the through hole.

[0030] In this embodiment, the locking structure includes a cavity disposed inside the bottom bracket 7, and a second telescopic rod 18 is installed in the cavity. The output end of the second telescopic rod 18 passes downward through the bottom bracket 7. The upper end of the fixed base 2 is provided with a plurality of locking holes arranged in a circular array, and the locking holes are all located below the bottom bracket 7.

[0031] When it is necessary to lock the bottom bracket 7, simply control the extension of the second telescopic rod 18 so that its end is inserted into the corresponding locking hole. The whole operation is simple and quick.

[0032] In this embodiment, the bottom of the antenna mounting platform 6 is provided with several annular mounting slots, all of which are coaxial with the annular slots. An annular auxiliary frame 20 is rotatably connected in the mounting slot, and the auxiliary frame 20 is fixedly connected to the adjusting guide rail 13.

[0033] In this solution, by setting an auxiliary frame 20, the strength of the adjusting guide rail 13 is improved, and the adjusting guide rail 13 is prevented from deforming during use.

[0034] In this embodiment, an anti-tipping rod 19 is provided between the support column 4 and the fixed base 2.

[0035] By setting up anti-tipping rod 19, the support column 4 is prevented from tipping over, which would cause the antenna mounting platform 6 to fall.

[0036] In this embodiment, the mounting column 3, the first telescopic rod 15, the second telescopic rod 18, and the synchronizing rod 17 are electric telescopic rods.

[0037] Mounting column 3 uses an electric telescopic rod, which can drive the fixed base 2 to move up and down, thereby adjusting the height of the antenna array; in addition, the use of an electric telescopic rod allows operators to operate without entering the antenna cover 1.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
