[0079] Specifically, the controller 500 can be installed inside the box 100, or outside the box 100, or fixedly connected to the box 100, and the embodiment of the present invention does not specifically limit this. In the following embodiments, the controller 500 is installed inside the box 100 as an example for explanation. The controller 500 can be installed at one end inside the box 100 through the support seat 260, and the controller 500 can be arranged at intervals with the rotating module 200 along the length direction of the box 100.

[0080] Furthermore, the test instrument 600 can be installed inside the box 100, or outside the box 100, or fixedly connected to the box 100, and the embodiment of the present invention does not specifically limit this. In the following embodiments, the test instrument 600 is installed inside the box 100 as an example for explanation. The test instrument 600 can also be installed at one end of the box 100 through the support seat 260, and the test instrument 600 can be arranged at intervals with the controller 500 along the length direction of the box 100.

[0081] It should be noted that the test instrument 600 may include related instruments such as a power supply (not shown in the figure), a spectrum analyzer (not shown in the figure), and a signal source (not shown in the figure), and this embodiment of the present invention does not specifically limit this.

[0082] Please continue to see Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, according to another embodiment of the present invention, the moving module 300 includes: a horizontal moving component 310, which is arranged on the inner bottom plate of the box 100, and the horizontal moving component 310 is used to drive the test prototype 400 to move along the length direction of the box 100; a vertical moving component 320, which is arranged in the box 100, and the vertical moving component 320 is connected to the horizontal moving component 310, and the vertical moving component 320 is used to drive the test prototype 400 to move along the height direction of the box 100.

[0083] Specifically, the horizontal moving component 310 can be movably installed on the inner bottom plate of the box 100, and the extension direction of the horizontal moving component 310 can be parallel to the length direction of the box 100. The horizontal moving component 310 can move back and forth along the length direction of the box 100. The horizontal moving component 310 is configured in this way so that the test prototype 400 can move back and forth along the length direction of the box 100.

[0084] The vertical moving component 320 can be fixedly connected to the horizontal moving component 310, and the extension direction of the vertical moving component 320 can be parallel to the height direction of the box 100. The vertical moving component 320 can be raised and lowered in the height direction of the box 100. With this arrangement, the vertical moving component 320 can drive the test prototype 400 to move up and down along the height direction of the box 100.

[0085] Furthermore, the mobile module 300 also includes a reinforcing plate 330, one end of the reinforcing plate 330 can be fixedly connected to the horizontal moving component 310 by means of threaded connection, riveting or welding, and the other end of the reinforcing plate 330 can be fixedly connected to the vertical moving component 320 by means of threaded connection, riveting or welding. The reinforcing plate 330, the horizontal moving component 310 and the vertical moving component 320 can together form a triangular structure. Such a configuration can effectively improve the connection strength and rigidity between the horizontal moving component 310 and the vertical moving component 320, thereby improving the overall stability and reliability of the mobile module 300, and further ensuring the stability of the test prototype 400 during the movement process.

[0086] Please continue to see Figure 1-Figure 2 and Figure 5-Figure 7 As shown, according to another embodiment of the present invention, the horizontal moving component 310 includes: a guide rail 311, the guide rail 311 is connected to the inner bottom plate of the box body 100, and the guide rail 311 extends along the length direction of the box body 100; a moving seat 312, the moving seat 312 is movably connected to the guide rail 311, and the moving seat 312 is fixedly connected to the vertical moving component 320; a first driving member 313, the first driving member 313 is arranged at one end of the guide rail 311, and the first driving member 313 is transmission-connected to the moving seat 312, the first driving member 313 is electrically connected to the controller 500, and the first driving member 313 is used to drive the moving seat 312 to move along the length direction of the box body 100.

[0087] Specifically, the number of guide rails 311 can be two, and the two guide rails 311 can be installed on the inner bottom plate of the box body 100 in parallel and at intervals, and the extension direction of the two guide rails 311 is parallel to the length direction of the box body 100, wherein one end of the guide rail 311 can be arranged opposite to the rotating module 200 and at intervals, and such an arrangement can make the installation spacing of the guide rail 311 larger, thereby improving the stability and reliability of the horizontal moving assembly 310 after installation. The moving seat 312 can be slidably installed on the guide rail 311, and the moving seat 312 can slide relative to the guide rail 311 along the extension direction of the guide rail 311. Among them, the moving seat 312 can be used to install and fix the vertical moving assembly 320. Such an arrangement can drive the vertical moving assembly 320 to move along the extension direction of the guide rail 311 through the moving seat 312, thereby realizing the reciprocating movement of the test prototype 400 in the horizontal direction.

[0088] The first driving member 313 can be fixedly installed at the end of the guide rail 311. The first driving member 313 can be connected to the controller 500 through a cable. The controller 500 can provide the first driving member 313 with a control signal while providing power to the first driving member 313, so as to control the start and stop state of the first driving member 313.

[0089] In a specific implementation, the first driving member 313 may be a servo motor, which can drive the moving seat 312 to move quickly. The servo motor may be connected to the moving seat 312 through a synchronous belt (not shown in the figure), and the synchronous belt may be fixedly connected to the moving seat 312. When the servo motor rotates, it drives the synchronous belt to rotate, and the synchronous belt may drive the moving seat 312 to move linearly on the guide rail 311, so that the moving seat 312 may drive the vertical moving assembly 320 to move back and forth.

[0090] It should be noted that the effective travel of the synchronous belt is relatively large, the transmission is stable, and the transmission ratio is relatively large, thereby effectively improving the running speed of the moving seat 312.

[0091] In another specific implementation, the first driving member 313 may be an electric push rod, which may be electrically connected to the controller 500 via a cable, and the push rod of the electric push rod may be fixedly connected to the moving seat 312, and the electric push rod may push the moving seat 312 to perform linear motion along the extension direction of the guide rail 311. In this way, the controller 500 may control the start and stop state of the electric push rod while providing power to the electric push rod.

[0092] Furthermore, the horizontal moving component 310 can also include a supporting base plate 315, and the guide rail 311 can be installed on the inner bottom plate of the box 100 through the supporting base plate 315. An adjusting caster 316 can be installed at the bottom of the supporting base plate 315. The adjusting caster 316 has a built-in height adjustment function. By manually adjusting the height of the adjusting caster 316, it can be ensured that the horizontal moving component 310 remains in a horizontal state after being installed on the inner bottom plate of the box 100. With such a configuration, the supporting base plate 315 and the adjusting caster 316 can cooperate with each other to achieve a leveling support function for the horizontal moving component 310.

[0093] Please continue to see Figure 1 , Figure 2 , Figure 5 as well as Figure 7-Figure 8 As shown, according to an optional embodiment of the present invention, the vertical moving component 320 includes: a slide rail 321, one end of which is fixedly connected to the moving seat 312, and the slide rail 321 extends along the height direction of the box 100; a slider 322, the slider 322 is movably connected to the slide rail 321, and the slider 322 is fixedly connected to the test prototype 400; a second driving member 323, the second driving member 323 is arranged at the other end of the slide rail 321, and the second driving member 323 is transmission-connected to the slider 322, the second driving member 323 is electrically connected to the controller 500, and the second driving member 323 is used to drive the slider 322 to move along the height direction of the box 100.

[0094] Specifically, one end of the slide rail 321 can be fixedly connected to the side of the moving seat 312 away from the inner bottom plate of the box 100, and the other end of the slide rail 321 is fixedly connected to the second driving member 323, and the slide rail 321 extends along the height direction of the box 100. The specific connection method can be threaded connection, welding or riveting. The slider 322 can be slidably installed on the slide rail 321, and the slider 322 can slide freely relative to the slide rail 321 along the extension direction of the slide rail 321.

In addition, the efficiency of the lead screw transmission is high, which can enable the slider 322 to achieve fast and stable linear motion.

[0098] It should be noted that the second drive member 323 has a power-off locking function, that is, when the power is suddenly disconnected, the second drive member 323 can remain locked and fixed. Such a setting can effectively prevent the test prototype 400 from falling as a whole in the vertical direction when the power is suddenly disconnected, thereby ensuring the safety and reliability of the vertical moving component 320.
