Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an antenna adjustment device and an antenna assembly. Background Technology

[0002] In the field of communication technology, reflector antennas are usually antennas with fixed feeds. However, as the antenna frequency band increases, the antenna beam narrows, making it increasingly difficult to align and maintain the antenna.

[0003] In some single-tube tower and guyed tower scenarios, external environmental factors such as wind load and vibration can cause the tower to sway. The link of the reflector antenna will become unstable due to the influence of the external environment. This is especially important for high-frequency reflector transmission scenarios. Utility Model Content

[0004] The purpose of this application is to provide an antenna adjustment device and antenna assembly that can solve the problem in related technologies where reflector antennas are easily affected by the environment, resulting in poor link stability.

[0005] In a first aspect, embodiments of this application provide an antenna adjustment device, comprising: Support components; A first attitude adjustment mechanism includes a first rotation drive source, a first active link, a first driven link, and a first swing beam. The first rotation drive source is disposed on the support member, and the output shaft of the first rotation drive source is rotatably connected to the first active link. The first active link is rotatably connected to the first driven link. The first swing beam has a first rotation connection part and a second rotation connection part. The first rotation connection part is rotatably disposed on the support member, and the first driven link is rotatably connected to the second rotation connection part. The first swing beam is used to connect with the sub-reflector of the reflector antenna. When the first rotary drive source is working, the first active link rotates and drives the first swing beam to rotate relative to the support member through the first driven link.

[0006] Secondly, embodiments of this application also provide an antenna assembly, including a reflector antenna and the aforementioned antenna adjustment device, wherein the reflector antenna includes a sub-reflector, and the antenna adjustment device is used to adjust the attitude of the sub-reflector.

[0007] In this embodiment, the support member of the antenna adjustment device provides support for the first attitude adjustment mechanism. The first attitude adjustment mechanism is used to adjust the pitch angle of the sub-reflector of the reflector antenna. Specifically, when the first rotary drive source is working, it drives the first active link to rotate. Specifically, the first active link rotates around the output shaft of the first rotary drive source. The second end of the first active link drives the first driven link to move. Then, the first driven link drives the first swing beam to rotate relative to the support member. The first swing beam is used to connect with the sub-reflector of the reflector antenna. Therefore, the first swing beam can drive the sub-reflector to adjust a certain pitch angle around the rotation axis of the first rotary connection.

[0008] Therefore, by controlling the first rotation drive source, the pitch angle of the sub-reflector can be adjusted, thereby controlling the angle of the sub-reflector relative to the main reflector. When affected by the external environment, even if the reflector antenna deviates from focus, the link can be kept stable and the signal can be transmitted stably by adjusting the angle of the sub-reflector relative to the main reflector.

[0009] Furthermore, by using the first active link and the first driven link as power transmission components, the rotational power of the first rotary drive source is converted into the rotational power of the first swing beam. Compared with structures such as gear sets as power transmission components, the link structure is simpler and less expensive. It does not require the meshing accuracy to be guaranteed like a gear set, so the installation requirements are lower. Moreover, the rotation angle of the first swing beam is equal to the rotation angle of the first active link, achieving a 1:1 transmission ratio, which is beneficial for accurately adjusting the attitude of the sub-reflector.

[0014] The antenna adjustment device and antenna assembly provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0015] Please refer to Figures 1-8 The antenna adjustment device disclosed in this application includes a support member 100 and a first attitude adjustment mechanism 200. The support member 100 serves as the mounting base for the first attitude adjustment mechanism 200 and provides support for the first attitude adjustment mechanism 200. The first attitude adjustment mechanism 200 is used to connect with the sub-reflector X and can adjust the pitch angle of the sub-reflector X.

[0016] refer to Figure 1 , Figure 2 as well as Figure 5 As shown, the first attitude adjustment mechanism 200 includes a first rotary drive source 210, a first active link 220, a first driven link 230, and a first swing beam 240. The first rotary drive source 210 is disposed on the support member 100. The output shaft of the first rotary drive source 210 is rotatably connected to the first active link 220. The first active link 220 is rotatably connected to the first driven link 230. The first swing beam 240 is provided with a first rotating connection part 241 and a second rotating connection part 242. The first rotating connection part 241 is rotatably disposed on the support member 100. The first driven link 230 is rotatably connected to the second rotating connection part 242.

[0017] The first rotary drive source 210 can be a drive source that provides rotational power, such as a drive motor or a pneumatic motor. This application embodiment does not limit the specific type of the first rotary drive source 210. The housing of the first rotary drive source 210 and the support member 100 can be directly connected by welding or other means, or indirectly connected by a connecting member or other structure, so as to fix the position of the housing of the first rotary drive source 210 relative to the support member 100.

[0018] Specifically, the output shaft of the first rotary drive source 210 is rotatably connected to the first end of the first active connecting rod 220, the second end of the first active connecting rod 220 is rotatably connected to the first end of the first driven connecting rod 230, and the second end of the first driven connecting rod 230 is rotatably connected to the second rotary connection portion 242 of the first swing beam 240. Optionally, the output shaft of the first rotary drive source 210 and the first end of the first active connecting rod 220, the second end of the first active connecting rod 220 and the first end of the first driven connecting rod 230, the second end of the first driven connecting rod 230 and the second rotary connection portion 242, and the first rotary connection portion 241 and the support member 100 can all be rotatably connected through the first rotating shaft, or through the first cylindrical protrusion and the first cylindrical groove that rotate together. This embodiment of the application does not limit this form of rotary connection.

[0019] The first swing beam 240 is used to connect to the sub-reflector X of the reflector antenna. Optionally, the first swing beam 240 and the sub-reflector X can be directly connected by welding, bonding, or other methods, or, refer to... Figure 5 As shown, the first swing beam 240 and the sub-reflector X can be indirectly connected through other components (such as the second attitude adjustment mechanism 300 mentioned later). In short, the first swing beam 240 can drive the sub-reflector X to rotate relative to the support member 100.

[0020] When the first rotary drive source 210 is working, the first active link 220 rotates and drives the first swing beam 240 to rotate relative to the support member 100 via the first driven link 230. Specifically, when the first rotary drive source 210 is working, it drives the first active link 220 to rotate, specifically the first driven link 230 rotates around the output shaft of the first rotary drive source 210. The second end of the first active link 220 drives the first driven link 230 to move, which in turn drives the first driven link 230 to rotate relative to the support member 100. The first swing beam 240 is used to connect with the sub-reflector X of the reflector antenna, so the first swing beam 240 can drive the sub-reflector X to adjust a certain pitch angle around the rotation axis of the first rotary connection part 241.

[0021] Therefore, by controlling the first rotation drive source 210, the pitch angle of the sub-reflector X can be adjusted, thereby controlling the angle of the sub-reflector X relative to the main reflector. When affected by the external environment, even if the reflector antenna deviates from focus, the link can be kept stable and the signal can be transmitted stably by adjusting the angle of the sub-reflector X relative to the main reflector.

[0022] Moreover, by using the first active link 220 and the first driven link 230 as power transmission components, the rotational power of the first rotary drive source 210 is converted into the rotational power of the first swing beam 240. Compared with structures such as gear sets as power transmission components, the link structure is simpler and has a lower cost. It does not need to ensure meshing accuracy like gear sets, so the installation requirements are lower.

[0023] In this embodiment, reference Figure 6 As shown, the support member 100, the first active link 220, the first driven link 230, and the first swing beam 240 can form a parallelogram structure. The first driven link 230 translates relative to the support member 100. The rotation angle of the first swing beam 240 is equal to the rotation angle of the first active link 220, achieving a 1:1 transmission ratio. The rotation angle of the first active link 220 is controlled by the first rotary drive source 210. Therefore, the rotation angle of the first swing beam 240 can be accurately controlled by the first rotary drive source 210, which is beneficial for accurately adjusting the attitude of the sub-reflector X.

[0024] Optionally, the first active link 220 is parallel to the rotation axis of the first rotary drive source 210, the first driven link 230 is parallel to the rotation axis of the first active link 220, the second rotary connection portion 242 of the first swing beam 240 is parallel to the rotation axis of the first driven link 230, and the first rotary connection portion 241 of the first swing beam 240 is parallel to the rotation axis of the support member 100.

[0025] In the alternative solutions of this application, refer to Figure 5 As shown, the first rotating connection part 241 is rotatably disposed on the support member 100 around the first axis S1, and the first attitude adjustment mechanism 200 can adjust the pitch angle of the sub-reflector X around the first axis S1.

[0026] The antenna adjustment device also includes a second attitude adjustment mechanism 300, which is disposed on the first swing beam 240. The second attitude adjustment mechanism 300 is used to connect with the sub-reflector X; that is, the first swing beam 240 is indirectly connected to the sub-reflector X through the second attitude adjustment mechanism 300. Thus, when the first rotation drive source 210 operates, the first swing beam 240 drives the sub-reflector X to rotate around the first axis S1 via the second attitude adjustment mechanism 300. The second attitude adjustment mechanism 300 can adjust the pitch angle of the sub-reflector X around the second axis S2, which intersects the first axis S1. Optionally, the second axis S2 and the first axis S1 can be perpendicular, or they can intersect but not be perpendicular.

[0027] The second attitude adjustment mechanism 300 may adopt the same structure as the first attitude adjustment mechanism 200 or a different structure. The embodiments of this application do not limit the specific structure and form of the second attitude adjustment mechanism 300.

[0028] In this embodiment, the antenna adjustment device is equipped with a second attitude adjustment mechanism 300. The second attitude adjustment mechanism 300 is combined with the first attitude adjustment mechanism 200 to adjust the pitch angle of the sub-reflector X from multiple angles, which is more conducive to accurately adjusting the attitude of the sub-reflector X, and more conducive to ensuring link stability, thereby further ensuring stable signal transmission.

[0029] Of course, in other embodiments, the antenna adjustment device may not have the second attitude adjustment mechanism 300, and may adjust the pitch angle of the sub-reflector X solely through the first attitude adjustment mechanism 200.

[0030] In an optional embodiment, the second attitude adjustment mechanism 300 includes a second rotary drive source 310, a second active link 320, a second driven link 330, and a second swing beam 340. The second rotary drive source 310 is disposed on the first swing beam 240. The output shaft of the second rotary drive source 310 is rotatably connected to the second active link 320. The second active link 320 is rotatably connected to the second driven link 330. The second swing beam 340 is provided with a third rotary connection portion 341 and a fourth rotary connection portion. The third rotary connection portion 341 is rotatably disposed on the first swing beam 240. The second driven link 330 is rotatably connected to the fourth rotary connection portion. The second rotary drive source 310 can be a drive source that provides rotational power, such as a drive motor or a pneumatic motor. This application embodiment does not limit the specific type of the second rotary drive source 310. The housing of the second rotary drive source 310 and the first swing beam 240 can be directly connected by welding or other methods, or indirectly connected by connecting parts or other structures, thereby fixing the position of the housing of the second rotary drive source 310 relative to the first swing beam 240.

[0031] Specifically, the output shaft of the second rotary drive source 310 is rotatably connected to the first end of the second active connecting rod 320, the second end of the second active connecting rod 320 is rotatably connected to the second end of the second driven connecting rod 330, and the second end of the second driven connecting rod 330 is rotatably connected to the fourth rotary connection portion of the second swing beam 340. Optionally, the output shaft of the second rotary drive source 310 and the first end of the second active connecting rod 320, the second end of the second active connecting rod 320 and the first end of the second driven connecting rod 330, the second end of the second driven connecting rod 330 and the fourth rotary connection portion, and the third rotary connection portion 341 and the second swing beam 340 can all be rotatably connected via the second rotating shaft, or via the rotatably fitted second cylindrical protrusion and second cylindrical groove. This embodiment of the application does not limit this rotatable connection form.

[0032] The second swing beam 340 is used to connect with the sub-reflector X. Optionally, the second swing beam 340 and the sub-reflector X can be directly connected by welding, bonding or other methods, or the second swing beam 340 can be indirectly connected to the sub-reflector X through other components. In short, the second swing beam 340 can drive the sub-reflector X to rotate relative to the first swing beam 240.

[0033] When the second rotary drive source 310 is working, the second active link 320 rotates and drives the second swing beam 340 to rotate relative to the first swing beam 240 through the second driven link 330. Specifically, when the second rotary drive source 310 is working, it drives the second active link 320 to rotate, specifically the second driven link 330 rotates around the output shaft of the second rotary drive source 310. The second end of the second active link 320 drives the second driven link 330 to move, and then the second driven link 330 drives the second swing beam 340 to rotate relative to the first swing beam 240. The second swing beam 340 is used to connect with the sub-reflector X, so the second swing beam 340 can drive the sub-reflector X to adjust a certain pitch angle around the second axis S2.

[0034] In this embodiment, the second attitude adjustment mechanism 300 adopts the same structure as the first attitude adjustment mechanism 200, that is, it uses the second active link 320 and the second driven link 330 as power transmission components to convert the rotational power of the second rotary drive source 310 into the rotational power of the second swing beam 340. Compared with structures such as gear sets as power transmission components, the link structure is simpler and has a lower cost. It does not need to ensure meshing accuracy like gear sets, which helps to further reduce installation requirements.

[0035] In this embodiment, the first swing beam 240, the second active link 320, the second driven link 330, and the second swing beam 340 can form a parallelogram structure. The second driven link 330 translates relative to the first swing beam 240, and the rotation angle of the second swing beam 340 is equal to the rotation angle of the second active link 320, achieving a 1:1 transmission ratio. The rotation angle of the second active link 320 is controlled by the second rotary drive source 310. Therefore, the rotation angle of the second swing beam 340 can be accurately controlled by the second rotary drive source 310, which is beneficial for accurately adjusting the attitude of the sub-reflector X.

[0036] Optionally, the second active link 320 is parallel to the rotation axis of the second rotary drive source 310, the second driven link 330 is parallel to the rotation axis of the second active link 320, the fourth rotary connection of the second swing beam 340 is parallel to the rotation axis of the second driven link 330, and the third rotary connection 341 of the second swing beam 340 is parallel to the rotation axis of the first swing beam 240.

[0037] In the alternative solutions of this application, refer to Figure 1 and Figure 2As shown, the antenna adjustment device also includes a transition control module 400, which is connected to the support member 100. The support member 100 can support the transition control module 400. Moreover, the transition control module 400 is communicatively connected to the first rotation drive source 210 and the second rotation drive source 310 respectively. The transition control module 400 is used to control the first rotation drive source 210 and the second rotation drive source 310 according to the attitude of the sub-reflector X.

[0038] Optionally, both the first rotary drive source 210 and the second rotary drive source 310 are drive motors. The switching control module 400 can communicate with the first rotary drive source 210 and the second rotary drive source 310 respectively via electrical connection lines. The switching control module 400 can supply power to the first rotary drive source 210 and the second rotary drive source 310 respectively, and can send control commands to the first rotary drive source 210 and the second rotary drive source 310 to control their rotation angles. Further optionally, the switching control module 400 includes an inertial navigation chip. The inertial navigation chip can detect the attitude of the sub-reflector X, and the switching control module 400 controls the first rotary drive source 210 and the second rotary drive source 310 based on the detection information from the inertial navigation chip.

[0039] In this embodiment, the antenna adjustment device is equipped with a transition control module 400. The transition control module 400 automatically controls the first rotation drive source 210 and the second rotation drive source 310 according to the attitude of the sub-reflector X, which is beneficial to adjust the attitude of the sub-reflector X more timely and accurately.

[0040] Of course, in other embodiments, the antenna adjustment device may not include the transfer control module 400, and the user may manually control the first rotation drive source 210 and the second rotation drive source 310 according to the attitude of the sub-reflector X.

[0041] In the alternative solutions of this application, refer to Figure 5 As shown, one of the support member 100 and the first swing beam 240 is provided with a first limiting structure 710.

During the rotation of the first swing beam 240 relative to the support member 100, the other of the support member 100 and the first swing beam 240 makes limiting contact with the first limiting structure 710.

[0042] The first limiting structure 710 can be a limiting protrusion, a limiting groove, or other structures. The limiting protrusion can be a block protrusion, a strip protrusion, or other structures. The block protrusion can be a square protrusion, a circular protrusion, or other structures. The embodiments of this application do not limit the specific structure of the first limiting structure 710.

Specifically, the connecting screw 831 passes through the first rotating component and extends into the rotating shaft 810. The connecting screw 831 and the rotating shaft 810 are connected by threads. Of course, the rotating shaft 810 and the first rotating component may be fixedly connected in other ways. The antenna adjustment device may further include a bearing end cover 840 and a bearing retaining ring 850. Along the circumference of the rotating shaft 810, the bearing end cover 840 and the bearing retaining ring 850 are respectively matched with the bearing 830 for limiting. The bearing end cover 840 is used to prevent external impurities from entering the bearing 830, and the bearing retaining ring 850 is used to prevent the outer ring of the bearing 830 from moving axially along the rotating shaft 810.

[0056] Further optionally, the antenna adjustment device may also include an end cap screw 841, and the bearing end cap 840 is connected to the rotating shaft 810 via the end cap screw 841; the antenna adjustment device may also include a retaining ring screw, and the bearing retaining ring 850 is connected to the second rotating member via the retaining ring screw.

[0057] In this embodiment, the first attitude adjustment mechanism 200 and the second attitude adjustment mechanism 300 are rotatably connected by a rotating shaft 810. The addition of a bearing 830 further reduces friction and ensures that the two rotatably connected parts rotate more smoothly relative to each other.

[0058] Of course, in other embodiments, the antenna adjustment device may not have the bearing 830, and the first rotating member and the second rotating member may only be rotated together by the rotating shaft 810.

[0059] In a further embodiment, reference is made to... Figure 8 As shown, the rotating shaft 810 is provided with a stepped protrusion 811, which is located between the first rotating member and the second rotating member. The stepped protrusion 811 is in a limiting engagement with the first rotating member along the second direction B, and the stepped protrusion 811 is in a limiting engagement with the second rotating member in the opposite direction of the second direction B. The second direction B is parallel to the axial direction of the rotating shaft 810. That is, during the relative rotation of the first rotating member and the second rotating member, the stepped protrusion 811 is in limiting contact with the first rotating member, or the stepped protrusion 811 is in limiting contact with the second rotating member.

[0060] Among them, the stepped protrusion 811 can be a block protrusion, a strip protrusion, etc. The strip protrusion has an arc-shaped structure or a ring-shaped structure, and the strip protrusion extends circumferentially along the rotating shaft 810.

[0061] Optionally, the step protrusion 811 and the pivot 810 can be an integral structure, specifically formed by welding; or, the step protrusion 811 and the pivot 810 can be separate structures, specifically connected by bonding or other methods.

[0062] In this embodiment, the rotating shaft 810 is further provided with a stepped protrusion 811. The stepped protrusion 811 axially limits the relative rotation of the first rotating member and the second rotating member, preventing axial displacement of the first rotating member and the second rotating member during relative rotation, which is beneficial to improving rotational stability.

[0063] Of course, in other embodiments, the rotating shaft 810 may not have the stepped protrusion 811, and the first rotating member and the second rotating member may be directly limited and fitted along the axial direction of the rotating shaft 810.

[0064] In one optional embodiment, along the direction of the second axis S2, a third rotating connection 341 is provided on one side of the second swing beam 340, and a fifth rotating connection 243 is provided at one end of the first swing beam 240, that is, the number of the third rotating connection 341 and the fifth rotating connection 243 is one.

[0065] In another embodiment, reference Figure 5 As shown, along the direction of the second axis S2, the second swing beam 340 has a third rotating connection part 341 on both opposite sides, and the first swing beam 240 has a fifth rotating connection part 243 at both opposite ends. Each third rotating connection part 341 is rotatably connected to each fifth rotating connection part 243. That is, there are two third rotating connection parts 341 and two fifth rotating connection parts 243, and the third rotating connection parts 341 and the fifth rotating connection parts 243 are rotatably connected in a one-to-one correspondence.

[0066] In this embodiment, the first swing beam 240 and the second swing beam 340 are rotated at at least two locations. The increased number of rotational connection points and the larger rotational connection area allow the first swing beam 240 to provide rotational support from both opposite sides of the second swing beam 340, which helps to improve the rotational stability of the second swing beam 340 relative to the first swing beam 240.

[0067] In the alternative solutions of this application, refer to Figure 1 , Figure 2 as well as Figure 4As shown, the antenna adjustment device also includes a support assembly 500 and a focal length adjustment mechanism 600. The focal length adjustment mechanism 600 is disposed on the support assembly 500 and connected to the support member 100. Optionally, the focal length adjustment mechanism 600 can be directly disposed on the support assembly 500, or the focal length adjustment mechanism 600 can be indirectly disposed on the support assembly 500, specifically through the adapter control module 400 mentioned above; the focal length adjustment mechanism 600 and the support member 100 can be fixedly connected by welding, bonding, or other methods.

[0068] The focus adjustment mechanism 600 is used to adjust the position of the sub-reflector X along the first direction A, that is, to adjust the position of the support member 100 and the first attitude adjustment mechanism 200 relative to the support assembly 500 along the first direction A. The first direction A intersects the plane formed by the first axis S1 and the second axis S2. Optionally, the first direction A may be perpendicular to the plane formed by the first axis S1 and the second axis S2, or the first direction A may intersect the plane formed by the first axis S1 and the second axis S2 but not be perpendicular to it.

[0069] Optionally, refer to Figures 1-3 As shown, the support assembly 500 supports the focus adjustment mechanism 600, the transfer control module 400, the support member 100, the first attitude adjustment mechanism 200, and the second attitude adjustment mechanism 300. Specifically, the support assembly 500 includes a support frame 510, a first base 520, a second base 530, and a support 540. The support frame 510 forms a space to accommodate the support 540, the transfer control module 400, the support member 100, the first attitude adjustment mechanism 200, and the second attitude adjustment mechanism 300. The first base 520 and the second base 530 are respectively connected to the support frame 510. The first base 520 is connected to the support frame 510, and the second base 530 is connected to the support frame 510 by welding, bonding, or other methods. The second base 530 serves as a load-bearing component for mounting the support frame 510, and is also designed with a foolproof design, serving as the outlet for the transmission cable. The first base 520 acts as a buckle between the support frame 510 and the second base 530, enabling the first base 520 and the second base 530 to jointly clamp the support frame 510 and install the entire support frame 510. The support 540 is connected to the second base 530, specifically by welding, bonding, or other methods.

[0070] In this embodiment, the antenna adjustment device is equipped with a support component 500 and a focal length adjustment mechanism 600. The support component 500 provides support for the focal length adjustment mechanism 600, which can drive the first attitude adjustment mechanism 200 and the sub-reflector X to move along the first direction A to adjust the focal length of the reflector antenna. This is more conducive to ensuring link stability and guaranteeing stable signal transmission.

[0071] Of course, in other embodiments, the antenna adjustment device may not have the focal length adjustment mechanism 600, and the support member 100 may be provided on the support assembly 500. Optionally, the support member 100 is connected to the support assembly 500 through the adapter control module 400.

[0072] In a further embodiment, reference is made to... Figure 4 As shown, the focus adjustment mechanism 600 includes a rotating sleeve 610, an abutment member 630, and a moving member 620. The rotating sleeve 610 is rotatable relative to the moving member 620. The abutment member 630 is used to axially limit the rotating sleeve 610, and the moving member 620 is used to move along a first direction A. Specifically, the abutment member 630 is connected to the support assembly 500 via a fastener 640, and the abutment member 630 and the support assembly 500 can jointly clamp the rotating sleeve 610.

[0073] Optionally, refer to Figure 2 and Figure 4 As shown, the abutment 630 and the support 540 are connected by fasteners 640, and the abutment 630 and the support 540 can jointly clamp the rotating sleeve 610; Reference Figure 4 As shown, the rotating sleeve 610 may be provided with a bent portion 611. The bent portion 611 protrudes from the inner wall surface of the rotating sleeve 610. The abutment member 630 and the support member 100 can jointly clamp the bent portion 611, thereby fixing the circumferential position of the rotating sleeve 610.

[0074] A rotating sleeve 610 is fitted around the movable member 620. The axis of the rotating sleeve 610 is parallel to the first direction A, and the rotating sleeve 610 and the movable member 620 are connected by threads. Furthermore, the movable member 620 is connected to the support member 100. Optionally, the movable member 620 and the support member 100 can be fixedly connected by welding, bonding, or other methods. Further, the movable member 620 can be connected to the base 110 (described later) via a transfer control module 400.

[0075] With the fastener 640 in the first tightened state, the abutment 630 and the support assembly 500 release the rotating sleeve 610, allowing the rotating sleeve 610 to rotate relative to the movable member 620, thereby causing the movable member 620 to move relative to the rotating sleeve 610 along the first direction A. Specifically, when the user controls the rotating sleeve 610 to rotate, since the abutment 630 and the support member 100 jointly clamp the rotating sleeve 610, the rotating sleeve 610 can only rotate in place, that is, the rotating sleeve 610 will not move along the first direction A, thus enabling the movable member 620 to move relative to the rotating sleeve 610 along the first direction A. The movable member 620 drives the support member 100, the first attitude adjustment mechanism 200, the second attitude adjustment mechanism 300, and the sub-reflector X to move along the first direction A, thereby adjusting the focal length of the reflector antenna.

[0076] With the fastener 640 in the second fastening state, the abutment 630 and the support assembly 500 clamp the rotating sleeve 610, and the rotating sleeve 610 is fixed relative to the moving part 620. At this time, the rotating sleeve 610 cannot be moved or rotated. The support 100, the first attitude adjustment mechanism 200, the second attitude adjustment mechanism 300 and the sub-reflector X are fixed in position along the first direction A, and the focal length of the reflector antenna is constant.

[0077] In this case, the fastening force of the fastener 640 in the first fastening state is less than the fastening force in the second fastening state.

[0078] Optionally, the fastener 640 can be a bolt, screw, or other threaded fastener. When the fastener 640 is in the first tightening state, it indicates that the tightness of the fastener 640 is relatively small; when the fastener 640 is in the second tightening state, it indicates that the tightness of the fastener 640 is relatively large. The number of fasteners 640 can be one; or, multiple fasteners 640 can be spaced apart along the circumference of the rotating sleeve 610. In this way, multiple fasteners 640 respectively connect different positions of the abutment 630 and different positions of the support assembly 500, so that the abutment 630 and the support assembly 500 clamp different positions of the rotating sleeve 610, which is more conducive to the stable rotation or stable fixation of the overall structure of the rotating sleeve 610.

[0079] In this embodiment, the focus adjustment mechanism 600 achieves focus adjustment through a threaded rotating sleeve 610 and a moving part 620. Specifically, when the fastener 640 is not tightened, the rotating sleeve 610 can be manually controlled to adjust the axial position of the moving part 620. After the axial position is adjusted, the fastener 640 is tightened to fix the moving part 620 and the rotating sleeve 610 relative to each other, thus preventing the focus of the reflector antenna from being affected during subsequent pitch angle adjustments. Moreover, the threaded engagement method enables stepless focus adjustment, which is more conducive to accurately adjusting the focus of the reflector antenna.

[0080] Optionally, the movable part 620 can move 6 mm along the first direction A.

[0081] Of course, in other embodiments, the focal length adjustment mechanism 600 may also adopt other structures besides the rotating sleeve 610 and the moving part 620, as long as it can adjust the position of the sub-reflecting surface X along the first direction A.

[0082] In the alternative solutions of this application, refer to Figures 1-2 as well as Figures 5-6As shown, the support member 100 includes a base 110 and a support beam 120. A first rotary drive source 210 is disposed on the base 110. The first end of the support beam 120 is connected to the base 110. A first rotating connection part 241 is rotatably disposed on the second end of the support beam 120. The extension direction of the support beam 120 is parallel to the extension direction of the first driven connecting rod 230.

[0083] Optionally, refer to Figure 5 As shown, the housing of the first rotary drive source 210 can be mounted on the base 110 via a connector, the first limiting structure 710 is mounted on the second end of the support beam 120, and the transfer control module 400 is located on the side of the base 110 facing away from the support beam 120. The transfer control module 400 and the base 110 are fixedly connected by welding, bolts, or other means. The support beam 120 and the base 110 can be an integral structure, or they can be separate structures, which can be fixedly connected by welding, bolts, or other means.

[0084] In this embodiment, the support member 100 is provided with a support beam 120 that extends in the same direction as the first driven link 230. This facilitates the installation of a base 110 at the first end of the support beam 120 to mount the first rotary drive source 210, and also facilitates the installation of the first swing beam 240 at the second end of the support beam 120, which helps to simplify the structure of the support member 100.

[0085] Of course, in other embodiments, the support member 100 may not include the base 110 and the support beam 120, and the support member 100 may be configured with other structures.

[0086] In one optional embodiment, there is one support beam 120. Along the direction of the rotation axis of the first swing beam 240, that is, along the direction of the first axis S1, a first rotating connection part 241 is provided on one side of the first swing beam 240, and the first rotating connection part 241 is rotatably connected to the support beam 120.

[0087] In another embodiment, reference Figure 5 As shown, there are at least two support beams 120. The first attitude adjustment mechanism 200 is located between two of the support beams 120. Along the direction of the rotation axis of the first swing beam 240, first rotating connection parts 241 are provided on both opposite sides of the first swing beam 240. Each first rotating connection part 241 is rotatably connected to the second end of two of the support beams 120. That is, there are two first rotating connection parts 241 and two support beams 120, and the first rotating connection parts 241 and the support beams 120 are rotatably connected in a one-to-one correspondence.

[0088] In this embodiment, the support beam 120 and the first swing beam 240 are rotated at at least two locations. The increased number of rotational connection points and the larger rotational connection area allow the support beam 120 to provide rotational support to the first swing beam 240 from opposite sides, which helps to improve the rotational stability of the first swing beam 240 relative to the support beam 120.

[0089] In this embodiment, the first rotary drive source 210 and the second rotary drive source 310 are both located in the space between the two support beams 120, and the second rotary drive source 310 is located on the side of the first rotary drive source 210 closer to the sub-reflective surface X.

[0090] Based on the antenna adjustment device disclosed in this application, this application also discloses an antenna assembly, which includes the antenna adjustment device in the above embodiments and a reflector antenna. The reflector antenna includes a sub-reflector X, and the antenna adjustment device is used to adjust the attitude of the sub-reflector X.

[0091] Optionally, the antenna adjustment device includes a support 100, a first attitude adjustment mechanism 200, a second attitude adjustment mechanism 300, a support assembly 500, and a focal length adjustment mechanism 600, and uses the first attitude adjustment mechanism 200 and the second attitude adjustment mechanism 300 to achieve multi-angle adjustment of the pitch angle of the sub-reflector X.

[0092] In this embodiment, the antenna adjustment device of the antenna assembly uses the first attitude adjustment mechanism 200 to adjust the pitch angle of the sub-reflector X, avoiding deviation of the reflector antenna from focus, which helps to ensure link stability and guarantee stable signal transmission; moreover, the first rotation drive source 210 can accurately control the rotation angle of the first swing beam 240, which helps to accurately adjust the attitude of the sub-reflector X.

[0093] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
