Description

Technical Field

[0001] This application relates to the field of mobile communication technology, and more particularly to an antenna angle adjustment device and antenna assembly. Background Technology

[0002] In today's ever-evolving mobile communication technology, the performance of mobile networks is closely linked to the user experience. As a core component of wireless communication systems, the accuracy of base station antenna angle adjustment plays a decisive role in network coverage quality. With the gradual development of 5G and future 6G technologies, users are placing higher demands on mobile networks, such as lower latency, higher bandwidth, and wider signal coverage. This makes the optimization and adjustment of base station antennas a crucial aspect of improving network performance.

[0003] Currently, base station antennas are mostly installed and secured using mechanical clamps. In terms of vertical tilt adjustment, the mechanical downtilt angle is crucial, directly affecting the signal coverage and strength in the vertical direction. An improperly set vertical mechanical downtilt angle can lead to excessively strong signals at close range, causing interference, while signals at longer distances may fail to provide effective coverage, severely impacting the communication experience for staff. Therefore, accurately adjusting the vertical mechanical downtilt angle is essential for optimizing signal coverage and improving network capacity.

[0004] However, adjusting the horizontal azimuth angle currently faces numerous challenges. This adjustment primarily relies on manual operation, requiring workers to climb to the top of tall buildings or towers, loosen the clamps securing the antenna, manually adjust it to the appropriate azimuth, and then re-tighten it. This method is not only cumbersome but also poses significant safety risks. Workers face the danger of falls when operating at heights, and solo operation is extremely difficult and inefficient.

[0005] To ensure high-quality mobile network coverage, antenna beam pointing needs to be continuously adjusted based on actual signal coverage. While vertical beam adjustment can be achieved with electrically adjustable antennas, horizontal adjustments still rely on manual tower climbing. This not only requires qualified personnel, increasing labor costs, but also consumes a significant amount of time and effort for each adjustment, resulting in persistently high construction and maintenance costs for mobile networks.

[0006] Drive testing devices play a crucial role in routine network optimization. When a drive testing device detects poor signal in a certain area, the results must be fed back to the network optimization department, and staff will then be dispatched to manually adjust the antenna angles on-site. However, this method has significant drawbacks. From identifying the signal problem to arranging adjustments, the entire process is time-consuming and cannot promptly meet the staff's needs for network quality. Moreover, manual adjustments are difficult to precisely control the angle; often, after adjusting the signal in one location, the signal in other locations may deteriorate, making it difficult to achieve ideal signal distribution and establish efficient and stable mobile network coverage.

[0007] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Utility Model Content

Each of the two first side plates is provided with a slide rail, and the slide rail extends along the length direction of the first side plate. There are two support arms. Roller bearings are provided on the side of the two support arms that are far apart from each other. The roller bearings have a fastening end. A bearing seat is provided between the two support arms. The fastening end of the roller bearing is used to lock the support arm to the bearing seat. The bearing seat is provided with a first bearing corresponding to the two roller bearings. The bearing seat is fixedly connected to the push rod. The push rod drives the bearing seat and thus drives the roller bearing to slide along the extension direction of the slide rail.

The connector is equipped with a reducer, which is driven by the gear plate to drive the tilt adjustment mechanism and the antenna to rotate around the rod, thereby adjusting the azimuth angle of the antenna.

[0015] In some implementations, the power mechanism further includes a power splitter and a power input shaft; The power splitter is driven by the drive shaft, push rod, and power input shaft of the drive motor, so that the drive motor can drive the push rod and power input shaft independently respectively; the power input shaft is driven by the reducer, the drive motor drives the power input shaft to rotate, and then drives the reducer to rotate relative to the gear plate, thereby driving the downtilt adjustment mechanism and the antenna rod to rotate.

[0018] This application also provides an antenna assembly, including an antenna and the antenna angle adjustment device provided in any of the above embodiments.

[0019] The technical advantages of this application are as follows: 1. This application achieves antenna azimuth adjustment by setting up an azimuth adjustment mechanism, eliminating the need for personnel to climb and loosen clamps for adjustment, making it safer, more reliable, and reducing labor costs. The downtilt adjustment mechanism, installed independently on the azimuth adjustment mechanism, facilitates separate adjustment of the azimuth and downtilt angles, achieving coordinated optimization of antenna azimuth and downtilt adjustments. Adjusting the downtilt angle only requires sliding the support arm to different positions, making operation convenient and quick, effectively improving mobile network coverage quality and meeting the increasing communication needs of personnel.

In this application, the power mechanism can drive the push rod to slide the support arm along the extension direction of the slide rail, thereby realizing the automatic adjustment of the tilt angle; the reducer and the gear plate on the clamping part drive each other to realize the automatic adjustment of the azimuth angle. The adjustment accuracy is high and no amount of time and effort is required, which greatly reduces the cost of mobile network construction and maintenance, and is conducive to the formation of efficient and stable mobile network coverage.

[0021] 3. By setting up a power splitter, this application only requires one drive motor to drive the push rod and the reducer separately, which reduces the cost. Furthermore, it achieves coordinated optimization of antenna azimuth angle adjustment and downtilt angle adjustment. The structure is reasonable and highly practical. Attached Figure Description

These descriptions are appropriate when the devices are in the positions shown in the drawings. If the description of the positions of the devices changes, these directional indications also change accordingly.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] According to a specific embodiment provided in this application, see [link to specific embodiment]. Figure 1 and Figure 5 An antenna angle adjustment device includes an azimuth adjustment mechanism 100 and a downtilt adjustment mechanism 200. The downtilt adjustment mechanism 200 is mounted on the azimuth adjustment mechanism 100, and the antenna 400 is mounted on the downtilt adjustment mechanism 200. The azimuth adjustment mechanism 100 drives the downtilt adjustment mechanism 200 and the antenna 400 to rotate, thereby adjusting the azimuth angle of the antenna 400. The downtilt adjustment mechanism 200 includes a connector 210 mounted on the downtilt adjustment mechanism 200 and a support arm 220 slidably mounted on the connector 210. The connector 210 and the support arm 220 are respectively hinged to different positions of the antenna 400. The support arm 220 can be selectively fixed to different positions of the connector 210 to adjust the downtilt angle of the antenna 400.

[0032] The principle of the tilt angle adjustment mechanism 200 can be found in [reference needed]. Figure 2 One end of component a slides on component b. As component a slides, the length of the triangle formed by component b, component a, and component c at the corresponding point on component b also changes. This change in length can achieve a change in angle A (the angle formed between component a and component c), and the formula for calculating angle A is as follows:

[0033] In this embodiment, the support arm 220 is component a, the connector 210 is component b, and the antenna 400, which is hinged to the support arm 220 and the connector 210, is component c. The downtilt angle of the antenna 400 is angle A. Understandably, by sliding the support arm 220 on the connector 210 and fixing it at different positions on the connector 210, the downtilt angle of the antenna 400 can be flexibly changed, making the operation convenient and quick. The downtilt angle adjustment mechanism 200 is installed on the azimuth angle adjustment mechanism 100. The azimuth angle adjustment mechanism 100 is used to adjust the azimuth angle of the antenna 400, eliminating the need for operators to climb the tower to adjust the azimuth angle, making the operation safer and more reliable. Moreover, during azimuth adjustment, the azimuth adjustment mechanism 100 will drive the downtilt adjustment mechanism 200 and the antenna 400 to rotate together without affecting the downtilt angle; conversely, when adjusting the downtilt angle, the azimuth angle will not be affected. This achieves coordinated optimization of azimuth adjustment and downtilt angle adjustment of the antenna 400, improves the coverage quality of the mobile network, and meets the growing communication needs of staff.

[0034] Specifically, see Figure 1 and Figure 3 One end of the support arm 220 is equipped with a roller bearing 221, and the other end is hinged to the antenna 400. A slide rail 2113 is provided on the connector 210, and the roller bearing 221 is slidably connected to and fixed at any position on the slide rail 2113. The slide rail 2113 extends along the length of the connector 210, guiding the sliding of the support arm 220 and limiting its radial sway, allowing it to move only up and down, further reducing the potential impact on the azimuth angle during tilt angle adjustment. Furthermore, the sliding fit between the roller bearing 221 and the slide rail 2113 makes the movement of the support arm 220 smoother and more stable, less prone to jamming, and more conducive to tilt angle adjustment.

[0035] See Figure 1 and Figure 5 The azimuth adjustment mechanism 100 includes at least one clamp 110, which is hinged to the connector 210 and can be engaged with the outside of the rod 500, thereby rotatably mounting the downtilt adjustment mechanism 200 and the antenna 400 on the rod 500. The first clamp portion 111 or the second clamp portion 112, which is hinged to the connector 210, is provided with a gear 113. For example, in this embodiment, the second clamp 110 is hinged to the connector 210 and is provided with a gear 113. A reducer 115 is mounted on the connector 210, and the reducer 115 is drivenly connected to the gear 113 to drive the downtilt adjustment mechanism 200 and the antenna 400 to rotate around the rod 500, thereby adjusting the azimuth angle of the antenna 400.

[0036] In a preferred embodiment, see Figure 3 and Figure 6The antenna angle adjustment device also includes a power mechanism 300, which can realize electric adjustment of azimuth and downtilt angles. This allows staff to remotely control and optimize the distribution of antenna signal 400. The adjustment is highly accurate and does not require a lot of time and effort, which greatly reduces the cost of mobile network construction and maintenance and is conducive to forming efficient and stable mobile network coverage.

[0037] Specifically, the power mechanism 300 includes a drive motor 310 and a push rod 320. Both the drive motor 310 and the push rod 320 are mounted on the side of the connector 210 facing the antenna 400. The push rod 320 is hinged to the support arm 220. The drive motor 310 drives the push rod 320 to run (the push rod 320 extends and retracts), thereby causing the roller bearing 221 to slide along the extension direction of the slide rail 2113 and fixing the roller bearing 221 at any position on the slide rail 2113. Conversely, the power mechanism 300 also includes another drive motor, which is drivenly connected to the reducer 115 and can drive the reducer 115 to rotate relative to the gear plate 113.

[0038] Of course, see 3 and above. Figure 6 In addition to multi-motor drive for electric adjustment, a single motor can also be used for drive. For example, the power mechanism 300 also includes a power splitter 330 and a power input shaft 340. The power splitter 330 is driven by the drive shaft of the drive motor 310, the push rod 320, and the power input shaft 340, so that the drive motor 310 can independently drive the push rod 320 and the power input shaft 340 respectively. The power input shaft 340 is driven by the reducer 115. When the drive motor 310 is selected in the control position of the reducer 115, the drive motor 310 drives the power input shaft 340 to rotate, which in turn drives the reducer to rotate relative to the gear plate 113, thereby driving the downtilt adjustment mechanism 200 and the antenna 400 to rotate around the rod 500, thus realizing azimuth angle adjustment. Conversely, when the drive motor 310 is selected in the control position of the control push rod 320, the drive motor 310 drives the push rod 320 to extend and retract, thereby driving the support arm 220 to slide on the connector 210 and drive the antenna 400 to achieve downtilt angle adjustment.

[0039] In this embodiment, by setting up a power splitter 330, only one drive motor 310 is needed to drive the push rod 320 and the reducer 115 respectively, which reduces costs and increases the integration of the device. It further realizes the coordinated optimization of antenna 400 azimuth angle adjustment and downtilt angle adjustment, and the structural setting is more reasonable and practical.

[0040] Furthermore, the antenna angle adjustment device also includes a controller integrated into the drive motor 310, which can control the drive motor 310 to drive the push rod 320 or the reducer 115, which is more conducive to the automatic adjustment of the antenna 400 downtilt angle and azimuth angle.

[0041] Preferably, see Figure 5 and Figure 6 There are two clamping parts 110, which are hinged to both ends of the connector 210 along its length. This facilitates the stable rotation of the azimuth adjustment mechanism 100 and the downtilt adjustment mechanism 200 and the antenna 400, thereby reducing the potential impact on the downtilt angle during azimuth adjustment. At this time, there are also two reducers 115 mounted on the connector 210, with both ends of the power input shaft 340 connected to the two reducers 115 respectively.

[0042] Specifically, see Figure 3 and Figure 5 The connector 210 includes a first base 211, a second base 212, and a connector 213. The first base 211 and the second base 212 are respectively located at both ends of the connector 213. The end of the connector 213 facing the first base 211 is provided with the aforementioned drive motor 310, push rod 320, power splitter 330, and power input shaft 340. The ends of the first base 211 and the second base 212 away from the connector 213 are respectively hinged to the aforementioned two clamps 110 and equipped with corresponding reducers 115. The first base 211 is also slidably engaged with the support arm 220, and the second base 212 is also hinged to the antenna 400. In addition, a first adjustment hole 2114 is provided on the first base 211, and a second adjustment hole 2123 is provided on the second base 212. Fasteners are inserted through the first adjustment hole 2114 and the second adjustment hole 2123, which are suitable for locking the first base 211 and the second base 212 to the connector 213 and adjusting the length of the connector 210.

[0043] In this embodiment, by setting the first adjustment hole 2114 and the second adjustment hole 2123, the operator can flexibly adjust the relative positions between the first base 211 and the connector 213, as well as between the second base 212 and the connector 213, so as to better adapt to antennas 400 of different lengths. It has strong applicability and is conducive to the mass production and use of antenna angle adjustment device.

[0044] Preferably, the first adjustment hole 2114 is a strip-shaped hole extending along the length of the first base 211, and the fastener is a bolt. This allows the operator to adjust the position without removing the fastener; simply loosen the bolt, move the first base 211 or the connector 213, and then tighten it again. The operation is convenient and quick. Conversely, the second adjustment hole 2123 is a strip-shaped hole extending along the length of the second base 212, and the fastener is also a bolt.

[0045] Specifically, see Figure 3The first base 211 includes a first main board 2111 and first side plates 2112 disposed on opposite sides of the first main board 2111. The number of first adjustment holes 2114 is three, which are respectively disposed on the first main board 2111 and the two first side plates 2112. Correspondingly, the second base 212 includes a second main board 2121 and second side plates 2122 disposed on opposite sides of the second main board 2121. The number of second adjustment holes 2123 is also three, which are respectively disposed on the second main board 2121 and the two second side plates 2122. This facilitates a stable connection between the first base 211, the connector 213 and the second base 212, resulting in higher structural strength.

[0046] Furthermore, each of the two first side plates 2112 of the first base 211 is provided with a slide rail 2113, which extends along the length of the first side plate 2112. At this time, there are two support arms 220, and each of the two support arms 220 has a roller bearing 221 on the side furthest from each other, with a fastening end. A bearing seat 222 is provided between the two support arms 220, and the fastening end of the roller bearing 221 is used to lock the support arm 220 to the bearing seat 222. A first bearing 223 is provided in the bearing seat 222 corresponding to each of the two roller bearings 221. The bearing seat 222 is fixedly connected to the push rod 320. For example, it is fixed by tightening with a fixing screw. The push rod 320 drives the bearing seat 222, thereby causing the roller bearing 221 to slide along the extension direction of the slide rail 2113.

[0047] In this embodiment, the inner ring of the roller bearing 221, the inner ring of the first bearing 223, and the support arm 220 are assembled into a fixed whole, while the bearing seat 222, the outer ring of the first bearing 223, the fixing screw, and the push rod 320 are another fixed whole. The two wholes can slide relative to each other. The outer ring of the roller bearing 221 is restricted within the slide rail 2113 and can only move up and down.

[0048] In this embodiment, by setting two support arms 220, the downtilt adjustment mechanism 200 can more stably drive the antenna 400 to move, thereby adjusting the downtilt angle of the antenna 400. Simultaneously, a bearing seat 222 and a first bearing 223 are provided between the two support arms 220, ensuring that the two support arms 220 can be driven synchronously by the push rod 320, and that the relative rotation between the support arms 220 and the bearing seat 222 is smoother and less jammed, which is beneficial for timely response to downtilt angle adjustments.

[0049] In addition, a third bearing 230 may be provided at the joint where the support arm 220 and the antenna 400 are hinged, as well as at the joint where the connector 210 (second base 212) and the antenna 400 are hinged, so as to make the rotation of the celestial body smoother and facilitate timely adjustment of the downtilt angle.

[0050] Specifically, see Figure 4Taking the hinged joint between the support arm 220 and the antenna 400 as an example, the antenna 400 has two mounting ears 240 on its back, corresponding to the two support arms 220 respectively. A fastener passes through the two support arms 220 and the mounting ears 240 to achieve the hinge between the support arm 220 and the antenna 400. The fastener is a bolt, and a third bearing 230 is installed on its exterior corresponding to the two support arms 220. A bearing seat is further fitted over the third bearing 230. In this embodiment, the bearing seat is formed on the sheet metal part (support arm 220) by a mold. The bolt, mounting ears 240, and inner ring of the third bearing 230 are assembled into a fixed whole, and the outer ring of the third bearing 230, the bearing seat, and the support arm 220 are another fixed whole. The two wholes can slide relative to each other. Of course, in practical applications, the bearing seat 222 formed on the sheet metal can also be replaced with an independent bearing seat 222. This is not limited here, and all are within the protection scope of this application.

[0051] Furthermore, see Figure 5 A second bearing 215 can also be provided at the hinged joint of the clamp 110 and the connector 210 to allow for flexible rotation of the antenna 400 azimuth angle. Specifically, a hinge hole 114 is provided on the first clamp part 111 or the second clamp part 112, and the connector 210 is provided with a support 214. A second bearing 215 is installed inside the support 214. Fasteners pass through the hinge hole 114 and the second bearing 215 to hinge the clamp 110 to the connector 210. These fasteners are bolts, which are fixed to the inner ring of the second bearing 215 and the gear plate 113. The support 214, the outer ring of the second bearing 215, the connector 210, and the reducer 115 are rotating bodies, enabling rotation of the downtilt adjustment mechanism 200 and the antenna 400.

[0052] This application also provides an antenna assembly, including an antenna 400 and the antenna angle adjustment device provided in any of the above embodiments.
