[0038] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0039] Reference Figure 1 and Figure 2 This invention provides an antenna adjustment device, which may include a housing 1, a first connecting shaft 2, a horizontal adjustment mechanism 3, a first fixing rod 4, an antenna 5, a second connecting shaft 6, a linear bearing 7, a pitch adjustment mechanism 8, and a second fixing rod 9, wherein:

[0040] The first connecting shaft 2 is vertically positioned (i.e., parallel to the vertical direction) and rotatably connected to the chassis 1. For example, the first connecting shaft 2 can be mounted on one side of the chassis 1, wherein the rotatable connection is achieved by providing two mounting bearings at both ends of the first connecting shaft 2, and the mounting bearings are fixed to the chassis 1. In one example, to improve the structural stability of the chassis 1, the chassis 1 is a sheet metal structure, i.e., the chassis 1 is manufactured by sheet metal processing, and, to be suitable for long-term use of the device in outdoor environments, the chassis 1 has a waterproof function.

[0041] The horizontal adjustment mechanism 3 is located inside the chassis 1 and is drivenly connected to the first connecting shaft 2. One end of the first fixing rod 4 is fixedly connected to the first connecting shaft 2. The antenna 5 is rotatably connected to the other end of the first fixing rod 4. When the horizontal adjustment mechanism 3 operates, it drives the first connecting shaft 2 to rotate horizontally. This rotation of the first rotating shaft causes the first fixing rod 4 to rotate, thereby adjusting the azimuth angle of the antenna 5 in the horizontal direction. In one example, the horizontal adjustment mechanism 3 can adjust the azimuth angle of the antenna 5 in the horizontal direction within a range of 0–120°. This azimuth angle adjustment range can meet the azimuth angle adjustment requirements in daily network optimization operations.

[0042] The second connecting shaft 6 is vertically positioned (i.e., parallel to the vertical direction) and rotatably connected to the housing 1. The linear bearing 7 is sleeved on the second connecting shaft 6. In one example, the central axis of the first connecting shaft 2 and the central axis of the second connecting shaft 6 are collinear, meaning the second connecting shaft 6 is also installed on the side of the housing 1, directly above the first connecting shaft 2. The rotatable connection is achieved by installing two mounting bearings at both ends of the second connecting shaft 6, which are fixed to the housing 1. The first connecting shaft 2, the second connecting shaft 6, the first fixing rod 4, and the second fixing rod 9 are located in the same plane. The pitch adjustment mechanism 8 is located inside the housing 1 and connected to the linear bearing 7. One end of the second fixing rod 9 is rotatably connected to the linear bearing 7, and the other end is fixed to the antenna 5. When the pitch adjustment mechanism 8 is activated, it drives the linear bearing 7 to perform linear motion in the vertical direction, thereby adjusting the pitch angle of the antenna 5 in the vertical direction. In one example, the pitch adjustment mechanism 8 can adjust the pitch angle of the antenna 5 in the vertical direction within a range of 0 to 45°. Based on this pitch angle adjustment range, the pitch angle adjustment requirements in daily network optimization operations can be met.

[0043] Reference Figure 1 As shown, in an optional embodiment of the invention, the horizontal adjustment mechanism 3 may include a first rotary motion output unit 301 and a transmission unit 302. The first rotary motion output unit 301 is used to output rotary motion and is fixed to the housing 1. The transmission unit 302 is connected to the output shaft of the first rotary motion output unit 301 and the first connecting shaft 2, respectively, so that the rotational force output by the first rotary motion output unit 301 can be transmitted to the first connecting shaft 2 via the transmission unit 302.

[0044] An optional embodiment of the invention, referring to... Figure 2As shown, the transmission unit 302 may include a first sprocket 3021, a second sprocket 3022, and a chain 3023. The first sprocket 3021 is coaxially fixed with the output shaft of the first rotary motion output unit 301 (i.e., the central axis of the first sprocket 3021 and the central axis of the output shaft of the first rotary motion output unit 301 are collinear, and the first sprocket 3021 is fixedly connected to its output shaft). The second sprocket 3022 is sleeved on the first connecting shaft 2 and coaxially fixed with the first connecting shaft 2 (i.e., the central axis of the second sprocket 3022 and the central axis of the first connecting shaft 2 are collinear, and the second sprocket 3022 is fixedly connected to the first connecting shaft 2). The chain 3023 meshes with the first sprocket 3021 and the second sprocket 3022 respectively. When the first rotary motion output unit 301 is working, it drives the first sprocket 3021 to rotate, thereby driving the first connecting shaft 2 to rotate through the chain 3023 meshing with the first sprocket 3021.

[0045] In another optional embodiment of the invention, the transmission unit 302 may include a first pulley, a second pulley, and a meshing belt. The connection relationship between the first pulley, the second pulley, and the meshing belt is described above in the context of the connection relationship between the first sprocket 3021, the second sprocket 3022, and the chain 3023.

[0046] An optional embodiment of the invention, referring to... Figure 2 As shown, the first rotary motion output unit 301 may include a stepper motor 3011 and a reducer 3012 stacked on top of the stepper motor 3011. The stepper motor 3011 is fixed to the housing 1, and the output shaft of the stepper motor 3011 is fixedly connected to the reducer 3012. The output shaft of the reducer 3012 is coaxially fixed to the first sprocket 3021. By adding a reducer 3012 to the stepper motor 3011, the rotational speed of the stepper motor 3011 can be reduced while the torque of the stepper motor 3011 can be increased, achieving high load with low torque rotation. Furthermore, a reducer 3012 with a self-locking function can be used, ensuring that the first rotary motion output unit 301 has excellent operational stability and safety even in harsh outdoor environments.

[0047] An optional embodiment of the invention, referring to... Figure 1 and Figure 2As shown, the pitch adjustment mechanism 8 may include an electric cylinder 801 and a connecting block 802. The electric cylinder 801 is fixed inside the housing 1. The connecting block 802 is fixedly connected to the output shaft of the electric cylinder 801. The connecting block 802 is sleeved on the outside of the linear bearing 7 and is movably connected to the linear bearing 7. The linear bearing 7 has a limiting groove that limits the connection block 802. When the linear bearing 7 rotates horizontally, the connecting block 802 remains stationary. That is, when the first connecting shaft 2 rotates, the second fixing rod 9 drives the linear bearing 7 to rotate synchronously, but the connecting block 802 fixedly connected to the electric cylinder 801 will not move. When adjusting the pitch angle of the antenna 5, when the output shaft of the electric cylinder 801 extends or retracts, the connecting block 802, due to the upper and lower limiting effect of the limiting groove, drives the linear bearing 7 to rise or fall synchronously. This changes the angle between the second fixing rod 9 and the linear bearing 7 to achieve the pitch angle adjustment of the antenna 5.

[0048] An optional embodiment of the invention, referring to... Figure 1 As shown, the side of the chassis 1 is also provided with several heat dissipation holes 10 for cooling the electric cylinder 801 and the stepper motor 3011. The heat dissipation holes 10 can be regular shapes that are easy to process, such as circles. Furthermore, those skilled in the art can determine the number of heat dissipation holes 10 according to actual needs, and no limitation is made here. The provision of heat dissipation holes 10 can extend the service life of components such as the electric cylinder 801, the reducer 3012, and the stepper motor 3011.

[0049] In an optional embodiment of the invention, the device may further include a controller located within the chassis 1. The controller is electrically connected to the electric cylinder 801 and the stepper motor 3011, respectively. The controller includes a wireless communication module for remotely controlling the operation of the electric cylinder 801 and the stepper motor 3011. In one example, the motor in the electric cylinder 801 may also be a stepper motor, and the controller can control the speed and direction of the stepper motor 3011 via remotely received transmission pulses and direction signals. Since the antenna 5 is typically installed on a high-altitude communication base station, remote automatic adjustment of the antenna 5's angle avoids the need for personnel to perform high-altitude operations (especially in persistently severe weather conditions where manual network optimization adjustments are impossible), improving the safety factor during network optimization work, and ensuring controllable adjustment precision of the antenna 5. This provides advantages such as strong optimization capability, high safety, high adjustment precision, and reduced labor costs. For example, the above-described embodiment of the invention can be widely applied to the rapid adjustment of antennas 5 in communication base stations in remote areas and / or densely populated areas.

[0050] In one optional embodiment of the invention, to further improve the structural stability of the device, refer to... Figure 1 and Figure 2As shown, a rotating block 11 is also provided on the outer side of the linear bearing 7, and the rotating block 11 is rotatably connected to the second fixed rod 9. The rotating block 11 is used to increase the connection area between the linear bearing 7 and the second fixed rod 9, thereby allowing for the selection of a linear bearing 7 with a smaller pipe diameter and reducing product costs.

[0051] An optional embodiment of the invention, referring to... Figure 1 As shown, the device also includes a connecting plate 12 for mounting the antenna 5. To ensure the installation stability of the antenna 5, the connecting plate 12 can be a sheet metal structure. One end of the connecting plate 12 is rotatably connected to the other end of the first fixing rod 4, and the middle part of the connecting plate 12 is fixed to the other end of the second fixing rod 9 by a locking screw 13.

[0052] In the above embodiments of the invention, a baffle can be added to the side of the chassis 1 where the first connecting shaft 2 is installed, depending on the actual scenario. The baffle isolates components such as the stepper motor 3011, electric cylinder 801, and reducer 3012 from the external environment, forming a well-sealed operating environment, thereby improving the service life of the components.

[0053] In summary, this invention discloses an antenna adjustment device, comprising a housing 1, a first connecting shaft 2, a horizontal adjustment mechanism 3, a first fixing rod 4, an antenna 5, a second connecting shaft 6, a linear bearing 7, a pitch adjustment mechanism 8, and a second fixing rod 9. The first connecting shaft 2 is vertically mounted and rotatably connected to the housing 1. The horizontal adjustment mechanism 3 is located inside the housing 1 and is drively connected to the first connecting shaft 2. One end of the first fixing rod 4 is fixedly connected to the first connecting shaft 2, and the antenna 5 is rotatably connected to the other end of the first fixing rod 4. When the horizontal adjustment mechanism 3 operates, it drives the first connecting shaft 2 to rotate horizontally, thereby adjusting the azimuth angle of the antenna 5 in the horizontal direction. The second connecting shaft 6 is vertically mounted and rotatably connected to the housing 1, and the linear bearing 7 is sleeved on the second connecting shaft 6. The pitch adjustment mechanism 8 is located inside the housing 1 and connected to the linear bearing 7. One end of the second fixing rod 9 is rotatably connected to the linear bearing 7, and the other end is fixed to the antenna 5. When the pitch adjustment mechanism 8 is activated, it drives the linear bearing 7 to perform linear motion in the vertical direction, thereby adjusting the pitch angle of the antenna 5 in the vertical direction. This invention optimizes the network by adjusting the horizontal and vertical angles of the antenna 5. It has advantages such as wide applicability and strong network optimization capabilities.
