Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and more specifically, to an antenna adjustment platform. Background Technology

[0002] Currently, multi-degree-of-freedom adjustment platforms play a crucial role in antenna measurement, especially in applications involving multi-band and precise spatial pose control, such as far-field testing systems, satellite tracking and simulation, and radar calibration. These platforms must be able to provide flexible movement and precise positioning of the load in three-dimensional space without sacrificing measurement accuracy.

[0003] However, existing multi-degree-of-freedom adjustment platforms lack an effective adaptive leveling mechanism. When encountering uneven ground or needing to frequently adjust the working position, operators must spend a lot of time and effort on manual leveling, which usually requires multiple people to work together and repeatedly try and place shims to make the load reach the required spatial pose. This is not only time-consuming and labor-intensive, but may also lead to errors in signal reception, affecting the final measurement results. Utility Model Content

[0004] The main purpose of this invention is to provide an antenna adjustment platform to solve the problem that the leveling method of the existing antenna adjustment platform not only increases the labor intensity of the staff but also affects the measurement results.

[0005] To achieve the above objectives, this utility model provides an antenna adjustment platform, comprising: a base; an adjustment device including a height-adjustable adjustment part disposed on and below the base for adjusting the height of the base; a main body rotatably disposed on the base; a disk movably disposed on the main body, the disk surface of which supports the antenna; a pitch adjustment mechanism connected to the disk for adjusting the pitch angle of the disk; and a translation mechanism disposed on and below the base for adjusting the position of the base; wherein, there are multiple adjustment devices, which are spaced apart along the length and / or width direction of the base.

[0006] Furthermore, the antenna adjustment platform also includes: a detection device, which is mounted on the base to detect the flatness of the base; wherein the height of the adjustment part of the adjustment device is adjusted according to the flatness detection value of the detection device.

[0007] Furthermore, the adjusting device is a foot; or, the adjusting device also includes a drive mechanism, which is drivenly connected to the adjusting part to drive the adjusting part to perform lifting and lowering movements.

[0008] Furthermore, the adjustment device also includes: an adjustment body; an electromagnetic component, including an electromagnet and a permanent magnet, one of which is disposed on the adjustment body and the other of which is disposed on the adjustment part; wherein, the electromagnet and the permanent magnet generate a mutual repulsive force to make the adjustment part suspend on the adjustment body.

[0009] Furthermore, the main body includes multiple plates connected end to end, each plate having weight-reduction holes; wherein, at least one plate is made of at least one of carbon fiber, aluminum alloy and titanium alloy.

[0010] Furthermore, the antenna adjustment platform also includes a mounting frame, which includes: a frame body, mounted on the main body; a connecting frame, which is rotatably mounted on the frame body, and the disk is rotatably mounted on the connecting frame; wherein, the pitch adjustment mechanism is connected to the connecting frame to drive the connecting frame to rotate relative to the frame body, thereby adjusting the pitch angle of the disk.

[0011] Furthermore, the pitch adjustment mechanism includes: an adjustment body; a telescopic part that is telescopically mounted on the adjustment body and connected to a connecting frame; and a knob structure connected to the telescopic part, wherein the extension of the telescopic part is adjusted by rotating the knob structure, thereby adjusting the pitch angle of the disc.

[0012] Furthermore, the antenna adjustment platform also includes a rotation mechanism, which includes: a base, mounted on a base; a rotating part, rotatably mounted on the base and connected to the main body; and a driving device, which is drivenly connected to the rotating part to drive the rotating part to rotate.

[0013] Furthermore, the translation mechanism includes multiple spaced wheels, each of which is rotatably mounted; wherein, the wheels are swivel wheels or universal wheels.

[0014] Furthermore, the antenna adjustment platform also includes a base, and the translation mechanism includes: a guide rail, which is mounted on the base; and a slider, which is slidably mounted on the guide rail. The slider is connected to the base to drive the base to slide synchronously.

[0015] By integrating adjustment devices, translation mechanisms, and elevation adjustment mechanisms, the antenna adjustment platform achieves precise adjustment of the antenna in terms of height, horizontal position, and elevation angle. Multiple adjustable devices with height adjustment capabilities enable rapid leveling of the base, while the translation mechanism ensures that the base and its components can be flexibly moved to the ideal position. The elevation adjustment mechanism provides precise control of the antenna's elevation angle. The combination of these three mechanisms allows for high-precision positioning of the antenna in three-dimensional space, significantly improving the accuracy and efficiency of testing and calibration. This solves the problem that existing antenna adjustment platforms not only increase the workload of operators but also affect measurement results. Furthermore, by setting multiple adjustment devices under the base, operators can independently complete leveling without complex tools or manual labor, improving operational efficiency and ensuring platform stability in various environments, effectively reducing test errors caused by improper operation or platform instability.

[0025] To address the problem that the existing antenna adjustment platform leveling methods not only increase the labor intensity of workers but also affect measurement results, this application provides an antenna adjustment platform.

[0026] like Figures 1 to 3 As shown, the antenna adjustment platform includes a base 10, an adjustment device 20, a main body 30, a disk 40, a pitch adjustment mechanism 50, and a translation mechanism 60. The adjustment device 20 includes a height-adjustable adjustment section, which is mounted on and below the base 10 to adjust the height of the base 10. The main body 30 is rotatably mounted on the base 10. The disk 40 is movably mounted on the main body 30, and its surface supports the antenna. The pitch adjustment mechanism 50 is connected to the disk 40 to adjust the pitch angle of the disk 40. The translation mechanism 60 is mounted on and below the base 10 to adjust the position of the base 10. Multiple adjustment devices 20 are provided, spaced apart along the length and / or width of the base 10.

[0027] By integrating the adjustment device 20, translation mechanism 60, and pitch adjustment mechanism 50, the antenna adjustment platform achieves precise adjustment of the antenna in terms of height, horizontal position, and pitch angle. Multiple adjustable devices 20 can be raised and lowered to quickly level the base 10. The translation mechanism 60 ensures that the base 10 and its components can be flexibly moved to the ideal position, while the pitch adjustment mechanism 50 provides fine control of the pitch angle of the disk 40. The combination of these three mechanisms enables the antenna to achieve high-precision positioning in three-dimensional space, significantly improving the accuracy and efficiency of testing and calibration. This solves the problem that the existing antenna adjustment platform leveling method not only increases the labor intensity of workers but also affects measurement results. Furthermore, by setting multiple adjustment devices 20 below the base 10, the operator can independently complete the leveling without complex tools or manual assistance, improving operational efficiency and ensuring the stability of the platform in various environments, effectively reducing test errors caused by improper operation or platform instability.

[0028] Optionally, the antenna adjustment platform also includes a detection device mounted on the base 10 to detect the flatness of the base 10. The height of the adjustment section of the adjustment device 20 is adjusted based on the flatness detection value from the detection device. In this way, the detection device can monitor the flatness of the base 10 in real time, ensuring the platform's levelness. When the flatness of the base 10 is detected to be inconsistent with the set standard, the system can automatically or semi-automatically adjust the height of the adjustment section of the adjustment device 20 to quickly achieve a level state.

[0029] Optionally, the detection device is a level.

[0030] Optionally, the adjustment device 20 can be a base; or, the adjustment device 20 can also include a drive mechanism connected to the adjustment unit to drive the adjustment unit to move up and down. This design, with the base located on the ground and manually adjustable, allows the antenna adjustment platform to quickly find a balance point under less-than-ideal ground conditions. The operator can quickly level the base 10 by adjusting the height of the base based on the flatness information fed back by the detection device. The drive mechanism, connected to the adjustment unit, can drive the adjustment unit to move up and down automatically. Through linkage with the detection device, the antenna adjustment platform can automatically calculate and adjust the flatness of the base 10 to the ideal state without manual intervention. This not only improves the speed and accuracy of leveling but also significantly reduces the operator's workload.

[0031] In this embodiment, the adjustment device 20 is a foot.

[0032] It should be noted that the structure of the adjustment device 20 is not limited to this and can be adjusted according to working conditions and usage requirements.

[0033] In other embodiments not shown in the accompanying drawings, the adjustment device 20 further includes an adjustment body and an electromagnetic component. The electromagnetic component includes an electromagnet and a permanent magnet, with one of the electromagnet and the permanent magnet disposed on the adjustment body and the other disposed on the adjustment part. A repulsive force is generated between the electromagnet and the permanent magnet, causing the adjustment part to levitate on the adjustment body. Thus, utilizing the repulsive force between the electromagnet and the permanent magnet, the adjustment part can achieve non-contact levitation on the adjustment body. This not only eliminates friction and gaps caused by mechanical contact, allowing for extremely fine position adjustments of the adjustment part, but also enables precise control of the height of the base 10, reducing long-term stability problems caused by mechanical wear.

[0034] like Figure 1As shown, the main body 30 includes multiple plates 31 connected end-to-end, each plate 31 having weight-reduction holes 311; wherein, at least one plate 31 is made of at least one of carbon fiber, aluminum alloy, and titanium alloy. Thus, by using lightweight, high-strength materials such as carbon fiber, aluminum alloy, or titanium alloy to manufacture at least one plate 31, combined with the weight-reduction holes 311 on the plate 31, the overall weight of the main body 30 is significantly reduced. This not only improves the mobility and portability of the antenna adjustment platform, making it easier to deploy quickly in different testing scenarios, but also ensures high structural rigidity. Furthermore, the above design allows for greater flexibility in material selection for the plate 31 to meet different usage requirements and operating conditions, and also enhances the processing flexibility for operators.

[0035] In this embodiment, the main body 30 includes four plates 31 connected end to end, each plate 31 having a weight-reduction hole 311, and each plate 31 being made of carbon fiber. In this way, the plates 31 made of carbon fiber can reduce weight while maintaining or even enhancing the structure's bending and torsional resistance and vibration suppression effect.

[0036] It should be noted that the number of plates 31 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the main body 30 includes three, five, six, or more plates 31 connected end to end.

[0037] It should be noted that the material selection for plate 31 is not limited to this and can be adjusted according to working conditions and usage requirements.

[0038] In other embodiments not shown in the accompanying drawings, the plate 31 is made of aluminum alloy or titanium alloy. Thus, the plate 31, made of aluminum alloy or titanium alloy, not only possesses the characteristics of being lightweight and high-strength, but also utilizes its excellent thermal conductivity to improve the heat dissipation efficiency of the main body 30, extending the service life of the main body 30. Furthermore, aluminum alloy and titanium alloy also have excellent corrosion resistance, resisting various environmental erosions and ensuring the long-term stable operation of the antenna adjustment platform outdoors and under harsh conditions.

[0039] like Figures 1 to 3As shown, the antenna adjustment platform also includes a mounting frame 70, which comprises a frame body 71 and a connecting frame 72. The frame body 71 is mounted on the main body 30, and the connecting frame 72 is rotatably mounted on the frame body 71. The disk 40 is rotatably mounted on the connecting frame 72. The pitch adjustment mechanism 50 is connected to the connecting frame 72 to drive the connecting frame 72 to rotate relative to the frame body 71, thereby adjusting the pitch angle of the disk 40. In this way, the rotatable mounting of the connecting frame 72 on the frame body 71 allows the pitch angle of the disk 40 to be continuously and smoothly adjusted via the motor control of the pitch adjustment mechanism 50. Compared to traditional fixed-angle adjustment or manual adjustment methods, the aforementioned rotatable connecting frame 72 design enables rapid and precise changes in the pitch angle of the disk 40, significantly improving operational convenience and testing efficiency.

[0040] Specifically, the flipping capability of the connecting frame 72 allows users to change the pitch attitude of the disk 40 independently without affecting the adjustment of other degrees of freedom, thereby adapting to more diverse antenna testing needs.

[0041] Optionally, the antenna adjustment platform also includes a motor 90, which is driven to connect to the disk 40 to drive the disk 40 to rotate relative to the connecting frame 72.

[0042] like Figure 1 and Figure 2 As shown, the pitch adjustment mechanism 50 includes an adjustment body 51, a telescopic part 52, and a knob structure 53. The telescopic part 52 is telescopically mounted on the adjustment body 51 and is connected to the connecting frame 72. The knob structure 53 is connected to the telescopic part 52; rotating the knob structure 53 adjusts the extension of the telescopic part 52, thereby adjusting the pitch angle of the antenna disc 40. Thus, the telescopic feature of the telescopic part 52, combined with the fine adjustment capability of the knob structure 53, allows users to adjust the pitch angle of the antenna disc 40 in a very intuitive way. When the knob structure 53 is rotated, the telescopic part 52 extends and retracts precisely, ensuring the accuracy and control flexibility of the pitch angle adjustment. Compared to cumbersome manual adjustment or complex electronic control systems, the combination of the knob structure 53 and the telescopic part 52 provides a more direct and responsive mechanical angle adjustment solution, enabling operators to quickly and accurately find the required pitch angle, significantly improving the user experience and testing efficiency of the antenna adjustment platform.

[0043] In this embodiment, the telescopic part 52 includes a first tube and a second tube nested together. The first tube and the second tube are threaded together. The first tube is fixedly connected to the adjusting body 51. The second tube is connected to the connecting frame 72 and the knob structure 53. By rotating the knob structure 53, the second tube is driven to extend or retract relative to the first tube, so as to adjust the extension of the telescopic part 52 and thereby adjust the pitch angle of the disc 40.

[0044] It should be noted that the structure of the telescopic part 52 is not limited to this and can be adjusted according to working conditions and usage requirements.

[0045] In other embodiments not shown in the accompanying drawings, the telescopic part 52 is a lead screw and nut mechanism. The lead screw of the lead screw and nut mechanism is connected to the knob structure 53, and the nut of the lead screw and nut mechanism is connected to the connecting frame 72. When the operator rotates the knob structure 53, the knob structure 53 drives the lead screw to rotate, and the nut drives the connecting frame 72 to move relative to the lead screw, so as to adjust the pitch angle of the disc 40.

[0046] In other embodiments not shown in the accompanying drawings, the telescopic part 52 includes a gear and a rack structure meshing with the gear. The gear is connected to the knob structure 53, and the rack structure is connected to the connecting frame 72. When the operator rotates the knob structure 53, the knob structure 53 drives the gear to rotate, and the rack structure drives the connecting frame 72 to perform telescopic movement to adjust the pitch angle of the disc 40.

[0047] Optionally, the antenna adjustment platform also includes a rotation mechanism 80, which includes a base, a rotating part, and a drive device 81. The base is mounted on the base 10, and the rotating part is rotatably mounted on the base and connected to the main body 30. The drive device 81 is driven by the rotating part to drive its rotation. Thus, through the drive device 81 and the rotating part, the main body 30 can achieve continuous and stable 360° rotation relative to the base 10 in the horizontal plane, thereby significantly expanding the range of motion of the antenna adjustment platform. This allows the antenna to be easily pointed at any horizontal target, meeting the requirements for high-precision and wide-range azimuth adjustment in antenna testing.

[0048] Optionally, the drive unit 81 is a motor.

[0049] In this embodiment, the translation mechanism 60 includes multiple spaced-apart wheels, each rotatably arranged. This reduces the antenna adjustment platform's reliance on flat ground, allowing it to maintain good mobility even on uneven surfaces, ensuring the platform can be stably moved to its designated location and broadening its applicability. Simultaneously, the rotatable nature of the wheels means they can adaptively overcome small obstacles, such as power lines and floor seams, further enhancing the platform's practicality and adaptability to different scenarios.

[0050] Optionally, the wheels can be omnidirectional or caster wheels. This allows the translation mechanism 60, using omnidirectional or caster wheels, to achieve 360° translation in any direction on the horizontal plane, facilitating adjustments to the spatial position of the antenna adjustment platform. Furthermore, this design allows for greater flexibility in wheel selection to meet diverse usage needs and working conditions, while also enhancing the processing flexibility of the operators.

[0051] In other embodiments not shown in the accompanying drawings, the antenna adjustment platform further includes a base, and the translation mechanism 60 includes a guide rail and a slider. The guide rail is mounted on the base. The slider is slidably mounted on the guide rail and connected to the base 10 to drive the base 10 to slide synchronously. Thus, by mounting the slider in the guide rail on the base and connecting it to the base 10, precise linear translation of the base 10 and its upper structure in the horizontal plane can be achieved, thereby enabling precise positioning of the antenna adjustment platform. Simultaneously, the design of the guide rail and slider translation mechanism not only provides the antenna adjustment platform with precise movement capabilities but also significantly enhances the overall stability of the platform, avoiding shaking and vibration caused by uneven ground or improper operation.

[0052] Optionally, the antenna adjustment platform includes a wireless communication module, which remotely controls and monitors the adjustment device, translation mechanism, and pitch adjustment mechanism via Bluetooth, Wi-Fi, or 4G / 5G networks.

[0053] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0054] The antenna adjustment platform integrates adjustment devices, a translation mechanism, and a pitch adjustment mechanism to achieve precise adjustment of the antenna in terms of height, horizontal position, and pitch angle. Multiple adjustable devices with height adjustment capabilities allow for rapid leveling of the base, while the translation mechanism ensures that the base and its components can be flexibly moved to the ideal position. The pitch adjustment mechanism provides fine control over the antenna's pitch angle. The combination of these three mechanisms enables high-precision positioning of the antenna in three-dimensional space, significantly improving the accuracy and efficiency of testing and calibration. This solves the problem that existing antenna adjustment platforms not only increase the workload of operators but also affect measurement results. Furthermore, by installing multiple adjustment devices under the base, operators can independently complete leveling without complex tools or manual labor, improving operational efficiency and ensuring the platform's stability in various environments, effectively reducing test errors caused by improper operation or platform instability.
