[0033] See also Figure 1 and Figure 2, shows a schematic diagram of an antenna zoom simulation device in one embodiment of the present application, the antenna zoom simulation device 100 includes an antenna unit 10, a load-bearing unit 30, a push rod unit 20, a rotating unit 40 and a driving unit 50, wherein the antenna unit 10 and the rotating unit 40 are movably connected, the rotating unit 40 is rotatably connected to the load-bearing unit 30, one end of the push rod unit 20 is movably set on the surface of the rotating unit 40, and the other end is movably set on the antenna unit 10, the driving unit 50 is set inside the rotating unit 40 and connected to the push rod unit 20, and the driving unit 50 is used to drive one end of the push rod unit 20 to move along a preset direction on the rotating unit 40, so that the relative angle between the antenna unit 10 and the rotating unit 40 is different. Through the push rod unit 20, one end of the antenna unit 10 can move along a preset direction on the surface of the rotating unit 40, so that the antenna unit 10 can be gathered or spread out relative to the surface of the rotating unit 40, so that the angle between the antenna unit 10 and the rotating unit 40 gradually increases or decreases. At the same time, the antenna unit 10 can rotate synchronously with the rotating unit 40, so as to adjust the spatial position and relative angle of the antenna unit 10 to change the focal position of the antenna unit 10 and achieve the zoom effect of the antenna unit 10. The antenna zoom simulation device 100 can be used to test and evaluate the antenna performance at different positions and angles, thereby improving the reliability and accuracy of the weapon system.

[0034] In this embodiment, the antenna unit 10 includes a mounting portion 11, multiple horn antennas 12 and a connecting rod portion 13. The mounting portion 11 includes a cross mounting frame 111, a mounting tube 112 and multiple fixing rods 113. The cross mounting frame 111 is fixedly mounted on the end of the rotating unit 40, and the mounting tube 112 is fixedly sleeved on the rotating unit 40. Each fixing rod 113 is fixedly arranged between the cross mounting frame 111 and the mounting tube 112, which effectively prevents the horn antenna 12 from loosening and stably mounts it on the cross mounting frame 111 through the connecting rod portion 13; the number of horn antennas 12 in this embodiment is four, and the connecting rod portion 13 adopts a connecting rod structure. One end of the four horn antennas 12 is hinged to the cross mounting frame 111 through two connecting rods, and the other end is respectively hinged to the corresponding push rod unit 20. Under the action of the driving unit 50, each horn antenna 12 rotates along with the corresponding push rod unit 20, so that each horn antenna 12 can be gathered or unfolded relative to the surface of the rotating unit 40, thereby changing the angles between each horn antenna 12 and the angle with the rotating unit 40, thereby realizing the unfolding or retracting of all the horn antennas 12.

[0035] In other embodiments, the performance of the horn antenna 12 is further improved by optimizing the design of the horn antenna 12. For example, by adjusting the number, shape, size, etc. of the horn antenna 12, better antenna gain, directivity and frequency response can be achieved. In addition, different types of horn antennas 12 can also be selected, such as half-wave horn antennas, parabolic antennas, etc., to meet different application requirements.

[0036] In other embodiments, the antenna units 10 can be arranged into multiple groups. For example, the antenna units 10 are arranged into two groups. Each group of antenna units 10 is arranged on the rotating unit 40. Each group of antenna units 10 is pushed by the corresponding push rod unit 20. Under the action of the driving unit 50, the push rod unit 20 can drive the two groups of antenna units 10 to move synchronously along the preset direction on the rotating unit 40, which can also meet the working requirements.

[0037] like Figure 1 As shown, Figure 2 As shown and Figure 3 As shown, the antenna zoom simulation device 100 has a zoom function, and can achieve a zoom effect by expanding or retracting the horn antenna 12 and controlling the focus position of the antenna unit 10 according to the communication distance requirements. Figure 1 He Ru Figure 3 The horn antenna 12 is shown in a converged state, and the antenna unit 10 is controlled to focus at 1 meter, which can reduce the effective receiving area and directivity of the horn antenna 12, thereby making the signal more concentrated and reducing signal interference. Figure 2 The horn antenna 12 shown is in an unfolded state, and the antenna unit 10 is controlled to focus at 15 meters, which can increase the effective receiving area and directivity of the horn antenna 12, and improve the gain and signal strength of the horn antenna 12. The antenna unit 10 can also generate a maximum field strength of 1-15 meters through the driving unit 50, thereby achieving a zoom effect of the horn antenna 12, so that the focal position of the horn antenna 12 can be flexibly adjusted and adjusted to adapt to different working scenarios and requirements, thereby improving the reliability and accuracy of the weapon system.

[0038] like Figure 1 As shown, Figure 4 As shown and Figure 5As shown, the push rod unit 20 is arranged inside the rotating unit 40, including a transmission part 21, a sliding part 22 and a push rod part 23, and the corresponding driving unit 50 includes a first driving part 51, and the first driving part 51 can adopt a first rotating motor, and the first driving part 51 is fixedly arranged in the rotating unit 40, and its output end is connected to the transmission part 21 and can drive the transmission part 21 to rotate, and the sliding part 22 is sleeved on the transmission part 21 and is threadedly connected with the transmission part 21. In this embodiment, the transmission part 21 adopts a screw rod, the output end of the first rotating motor is connected to the end of the screw rod, and the sliding part 22 is a sliding block, which is threadedly connected to the screw rod and can slide on the inner wall of the rotating unit 40; the push rod part 23 adopts four push rods, one end of each of the four push rods is hinged on the sliding part 22, and the other end is respectively hinged to the corresponding horn antenna 12. Under the action of the first driving part 51, the sliding part 22 moves along the preset direction, and the four push rod parts 23 and the connecting rod part 13 rotate, so that each horn antenna 12 rotates following the corresponding push rod part 23, and the angles between each horn antenna 12 and the angle with the rotating unit 40 are adjusted, thereby realizing the expansion or folding of all the horn antennas 12.

[0039] like Figure 3 As shown, Figure 6 As shown, the load-bearing unit 30 includes a load-bearing bracket 31, a base 32, two bearing boxes 33 and two pitch axes 34. The load-bearing bracket 31 is spliced ​​by a plurality of load-bearing rods. The hollow design of the load-bearing bracket 31 reduces the weight. The base 32 is arranged at the lower end of the load-bearing bracket 31. The base 32 is reserved with mounting holes to increase the stability and reliability of the load-bearing unit 30. The two bearing boxes 33 are arranged on opposite sides of the load-bearing bracket 31 and are used to support the rotating unit 40 and balance the center of gravity of the rotating unit 40. One end of the two pitch axes 34 is respectively rotatably connected to the bearing boxes 33, and the other end is fixedly connected to the rotating unit 40. The rotating unit 40 rotates between the two pitch axes 34 and forms two pivot points. The rotating unit 40 can rotate on the first axis connected by the two pivot points. In addition, the size and material of the load-bearing bracket 31, the base 32 and the bearing box 33 are not limited, as long as the entire load-bearing unit 30 can maintain balance and stability.

[0040] like Figure 3 As shown, Figure 6 As shown and Figure 8As shown, the present embodiment can further adopt a rotating unit 40 to adjust the position and angle of the antenna unit 10, so as to more accurately adjust the antenna unit 10. Specifically, the rotating unit 40 includes a first rotating part 41 and a second rotating part 42, and the corresponding driving unit 50 includes a second driving part 52 and a third driving part 53. The first rotating part 41 and the second rotating part 42 respectively include a first rotating shell and a second rotating shell, and the cross-section of the first rotating shell and the second rotating shell is circular, wherein the opposite sides of the first rotating part 41 are respectively fixedly connected to the two pitch axes 34, one end of the second rotating part 42 is rotatably connected to the first rotating part 41, and the other end is movably connected to the antenna unit 10. Under the action of the second driving part 52, the first rotating part 41 can rotate around the first axis, and the antenna unit 10 can rotate synchronously with the first rotating part 41. Under the action of the third driving part 53, the second rotating part 42 can rotate along the second axis intersecting with the first axis, and the antenna unit 10 can rotate synchronously with the second rotating part 42. The first axis and the second axis of this embodiment are orthogonal. It can be seen that the driving unit 50 adjusts the position and angle of the antenna unit on the first axis, the second axis and any degree of freedom in the above-mentioned preset directions, thereby further expanding the adjustment range of the antenna unit 10, adjusting the focal position of the antenna unit 10, and achieving the zoom effect of the antenna unit 10.

[0041] In other embodiments, if the antenna unit 10 needs to rotate within a fixed plane, only the second rotating part 42 is required, or if the antenna unit 10 needs to rotate in a vertical plane, only the first rotating part 41 is required. In short, different rotating unit 40 solutions can meet different application requirements and provide more precise and flexible rotation adjustment capabilities.

[0042] like Figure 3 As shown, Figure 6As shown, specifically, the second driving unit 52 is arranged in a carrying box 33, and drives the first rotating unit 41 to rotate along the first axis by controlling the rotation direction of the pitch axis 34, and drives the antenna unit 10 to adjust the directivity and gain. Specifically, the second driving unit 52 includes a second rotating motor 521 arranged in the carrying box 33 and a first reducer 522 connected thereto, wherein a first gear (not shown) and a second gear (not shown) are arranged inside the first reducer 522, the axial direction of the first gear is parallel to the output shaft of the second rotating motor 521, and the axial direction of the second gear is perpendicular to the axial direction of the first gear, so that the rotation direction of the second rotating motor 521 can be changed. The output end of the second rotating motor 521 is fixedly connected to the first gear and can drive the first gear to rotate, one side of the second gear is meshed with the first gear, and the other side is fixedly connected to the pitch axis 34, and the two pitch axes 34 are rotatably connected to the carrying box 33. Under the action of the second rotating motor 521, the first gear drives the second gear to rotate, and the second gear drives the pitch axis 34 to rotate, so that the two pitch axes 34 can drive the first rotating part 41 to rotate on the first axis to meet the working requirements. Through the series combination of the first gear and the second gear, the power is transmitted by step-by-step reduction and the rotation speed and torque are changed, which can improve the carrying capacity of the pitch axis 34.

[0043] In other embodiments, the second drive unit 52 may not include the first reducer 522, and the output shaft of the second rotary motor 521 may be directly connected to the pitch axis 34, eliminating the intermediate transmission process of the first reducer 522. Although this will reduce the reduction ratio, in some cases, the number of second drive units 52 can be reduced, thereby reducing maintenance costs.

[0044] like Figure 2 As shown, Figure 8 As shown, the third driving part 53 is composed of a third rotating motor 531 and a second reducer 532. The output end of the second reducer 532 is fixedly sleeved with a third gear (not shown). One end of the rotating shaft 533 is meshed with the third gear through a fourth gear (not shown), and the other end is fixedly connected with a rotating disk 534, and the rotating disk 534 is fixedly connected to the second rotating part 42. When the third rotating motor 531 rotates, the meshing of the third gear and the fourth gear will transmit power, so that the rotating shaft 533 and the rotating disk 534 rotate, thereby driving the second rotating part 42 to rotate, and the antenna unit 10 can also rotate with the second rotating part 42. Through the series combination of the third gear and the fourth gear, the power is transmitted and the rotation speed and torque are changed step by step. The third driving part 53 can improve the bearing capacity of the rotating shaft.

[0045] In other embodiments, the third driving unit 53 may not include the second reducer 532, thereby reducing the intermediate reduction transmission process, and the third rotating motor 531 is directly connected to the rotating shaft 533, which can also meet the working requirements.

[0046] like Figure 6 As shown, Figure 7 As shown and Figure 8 As shown, in the present embodiment, the antenna zoom simulation device 100 also includes a first limiting portion 61 arranged in the carrying box 33 and a second limiting portion 62 arranged in the first rotating portion 41, and the first limiting portion 61 and the second limiting portion 62 are respectively used to limit the rotation of the first rotating portion 41 and the second rotating portion 42 within a preset angle, thereby effectively avoiding accidental damage caused by excessive rotation, and also ensuring the stability and safety of the antenna zoom simulation device 100.

[0047] like Figure 6 As shown, Figure 7 As shown, specifically, the first limiting part 61 includes a limiting disk 611, a limiting plate 612, a limiting switch 613 and a touch block 614, wherein the limiting disk 611 is arranged in the carrying box 33 and fixedly connected to the end of the pitch axis 34, the limiting plate 612 is fixedly arranged on the inner wall of the carrying box 33 and located on one side of the limiting disk 611, the limiting switch 613 is arranged on the limiting plate 612, and the touch block 614 is arranged on the outer wall of the limiting disk 611. Under the driving action of the second driving part 52, the limiting disk 611 can rotate synchronously with the pitch axis 34, when the limiting disk 611 rotates relative to the limiting plate 612, the touch block 614 can rotate synchronously with the limiting disk 611 and touch the limit switch 613, at this time, the second rotary motor 521 can obtain the limit signal emitted by the limit switch 613, so that the second rotary motor 521 can be turned off or on.

[0048] The above-mentioned limit switch 613 includes a positive limit switch 6131, a negative limit switch 6132 and a mechanical switch 6133 which are spaced apart on the limit plate. The touch block 614 can rotate and touch the positive limit switch 6131 or the negative limit switch 6132, and the mechanical switch 6133 is triggered at the same time. When the positive limit switch 6131 and the negative limit switch 6132 are damaged, the mechanical switch 6133 can be used as an alternative limit switch to continue to ensure the normal operation of the equipment. The mechanical switch 6133 of this embodiment includes an arc groove 6133-a and a protrusion 6133-b. The arc groove 6133-a is opened on the limit plate 612, and the protrusion 6133-b is set on the limit disk 611 and can slide in the arc groove 6133-a. When the touch block 614 follows the limit plate 612 to rotate to the positive limit switch 6131, the protrusion 6133-b will slide to one end of the arc groove 6133-a, and the limit disk 611 will stop rotating. Similarly, when the touch block 614 rotates to the negative limit switch 6132, the protrusion 6133-b will slide to the other end of the arc groove 6133-a, and the limit disk 611 will stop rotating. The positive limit switch 6131, the negative limit switch 6132 and the mechanical switch 6133 simultaneously play a limiting role, limiting the rotation of the limit plate 611 and the pitch axis 34 within 0-50°, ensuring that the first rotating part 41 also rotates within 0-50°, thereby improving the stability and reliability of the entire antenna zoom simulation device 100.

[0049] like Figure 2 As shown, Figure 8As shown, the second limit portion 62 includes a limit disk 611, a limit plate 612, a limit switch 613 and a touch block 614. Compared with the first limit portion 61, the difference is that the limit disk 611 is directly connected to the end of the rotating shaft 533 in the first rotating portion 41, while the limit plate 612 is located on the inner wall of the first rotating portion 41 and on one side of the limit disk 611. Under the driving action of the third driving portion 53, the limit disk 611 can rotate synchronously with the rotating shaft 533. When the limit disk 611 rotates relative to the limit plate 612, the touch block 614 can rotate synchronously with the limit disk 611 and touch the limit switch 613. At this time, the third rotating motor 531 can obtain the limit signal emitted by the limit switch 613, so that the third rotating motor 531 can be turned off or on. The limit switch 613 of the second limit part 62 also includes a positive limit switch 6131, a negative limit switch 6132 and a mechanical switch 6133. The mechanical switch 6133 includes an arc-shaped protrusion 6133-c arranged on the limit plate 612. When the touch block 614 passes through the positive limit switch 6131 or the negative limit switch 6131, one side of the touch block 614 simultaneously touches the end of the arc-shaped protrusion 6133-c, so that the limit plate 611 and the rotating shaft 533 rotate within the rotation angle range of 0-90°, thereby ensuring that the second rotating part 42 can rotate within the angle range of 0-90°, thereby improving the stability and reliability of the entire antenna zoom simulation device 100.
