Specifically, it is a test shielded darkroom that can automatically control each component with high precision. The box includes a test box body, a test turntable, and a test antenna array. The shielded darkroom can remotely control the turntable and antenna array in the box through software commands to build a diversified, high-precision OTA environment that is close to the actual use scenario of the DUT.
[0003] In the related art, when performing a shielding test on an object under test, in order to make the detection data of the object under test more accurate, it is necessary to detect signals at different angles in all directions of the object under test. Since the interior of the shielding chamber is in a sealed space when performing signal testing, and when the position and angle of the object under test need to be adjusted, the shielding chamber needs to be opened for adjustment. Therefore, in order to facilitate the adjustment of the angle of the object under test, a shielding chamber with a rotating turntable inside has appeared on the market. However, since the shielding chamber needs to be connected to the object under test during testing, when the object under test rotates continuously during the test, it is easy for the line to be entangled, causing damage to the shielding chamber.
[0004] Therefore, the prior art needs to be improved. Utility Model Content

[0018] 3. When detecting the signal of the object to be measured, place the object to be measured on the rotating table. Then, through the setting of the lifting member, extend the rotating table to a predetermined height. Next, detect the signal of the object to be measured.

Detailed Embodiment
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0026] The embodiment of the present application discloses a rotating platform for preventing wire winding. Refer toFigures 1 to 4 A rotation platform for preventing wire winding includes a base 1, a rotating table 2, and a rotating member 3. Specifically, the base 1 is integrally plate-shaped. From the vertical direction, the cross-section of the base 1 can be rectangular, circular, or other shapes. The base 1 is used to provide an installation foundation for other structures. The rotating table 2 is integrally circular plate-shaped. The rotating table 2 is rotatably connected to the upper side of the base 1. The rotation center of the rotating table 2 coincides with the axis of the rotating table 2 and the axis of the base 1. The upper side of the rotating table 2 is flat for placing the object to be measured. The rotating member 3 is arranged on the upper side of the base 1. The rotating member 3 is connected to the rotating table 2 so that the rotating table 2 can rotate on the base 1 along a predetermined posture. A slip ring 4 is arranged on the upper side of the base 1. The slip ring 4 is coaxially arranged with the rotating table 2. The slip ring 4 includes an outer ring 41 and an inner ring 42. The outer ring 41 of the slip ring 4 is fixedly connected to the base 1. The inner ring 42 of the slip ring 4 can rotate relative to the outer ring 41. The slip ring 4 has the function of transmitting electric energy, signals, or data during rotation, that is, the external circuit is input at the bottom of the outer ring 41 of the slip ring 4 and output from the upper part of the inner ring 42 of the slip ring 4. The inner ring 42 and the outer ring 41 of the slip ring 4 achieve transmission through electrical contact. A communication port conversion module 5 is arranged on the side of the rotating table 2. The communication port conversion module 5 is connected to the output of the upper part of the inner ring 42 of the slip ring 4 through a line and is connected to the object to be measured through a line. The communication port conversion module 5 includes interfaces such as DC conversion, USB conversion, and 10 Gigabit Ethernet port conversion. Therefore, when the object to be measured needs to be measured at different angles in the horizontal direction on the rotating table 2, the rotating table 2 is rotated by the rotating member 3, and the line connection between the communication port conversion module 5 and the inner ring 42 of the slip ring 4 is used to drive the rotation of the inner ring 42 of the slip ring 4, so that the line can be driven to rotate together. In this design method, through the setting of the slip ring 4, it is possible to avoid as much as possible the phenomenon of winding or entanglement of the external circuit connected to the communication port conversion module 5 during the rotation measurement of the object to be measured, thereby avoiding the phenomenon of equipment pulling damage caused by line entanglement as much as possible.
[0027] The rotating member 3 includes a worm reducer 31 and a rotating motor 32. The worm reducer 31 is arranged at the middle position of the base 1. The output end of the worm reducer 31 is connected to the rotating table 2. The housing of the rotating motor 32 is fixedly arranged on the base 1. The output shaft of the rotating motor 32 is drivingly connected to the input end of the worm reducer 31. When the rotating table 2 needs to rotate, only the rotating motor 32 needs to be started. The worm reducer 31 is used to reduce the speed and increase the torque to drive the rotation of the rotating table 2. Compared with only using the drive of the rotating motor 32, this design method has a lower speed, making the object to be measured rotate more smoothly on the rotating table 2. Compared with using the transmission of a gear reducer, in this design method, the structure of the worm reducer 31 is more compact, with low noise and small vibration during operation.
[0028] In order to further improve the rotational stability of the object to be measured on the rotating table 2, an annular guide rail 6 is arranged on the upper side of the base 1, and the annular guide rail 6 is arranged coaxially with the rotating table 2. A slider 21 is arranged on the lower side of the rotating table 2. There are multiple sliders 21, and the multiple sliders 21 are arranged in a circular shape and evenly spaced. The multiple sliders 21 are slidably connected to the annular guide rail 6. Therefore, when the rotating table 2 rotates, the annular guide rail 6 can provide a support for the rotating table 2, so that the rotating table 2 can rotate more stably, thereby minimizing the phenomenon that the object to be measured falls and is damaged due to the instability of the rotating table 2 during rotation measurement.
[0029] In order to improve the accuracy of the object to be measured during detection, a lifting member 7 is provided on the base 1. The lifting member 7 is used to lift the base 1 in the vertical direction. The lifting member 7 includes a lifting shell 71, a screw module (not shown in the figure) and a lifting motor (not shown in the figure). Specifically, the lifting shell 71 includes a plurality of shell units, and the plurality of shell units are connected in sequence to form a multi-section telescopic tube structure. The shell unit close to the base 1 is connected to the base 1, and the screw module and the lifting motor are both arranged inside the lifting shell 71. In this embodiment, the screw module is connected to the shell unit close to the base 1, and the lifting motor is transmission-connected to the screw module. When the lifting motor is started, the screw module drives the outermost shell unit to be lifted and lowered, so that the base 1 is upgraded, and the rotating table 2 can be lifted and lowered. A placement plate 8 is provided at the pipe mouth on one side of the shell unit away from the base 1. From the vertical direction, the cross-sectional area of the placement plate 8 is larger than the pipe mouth area of the shell unit. The overall structure can be installed through the placement plate 8. When the object to be tested is tested, the object to be tested is placed on the rotating table 2, and the object to be tested is placed in a predetermined position in the vertical direction through the lifting motor, and then the object to be tested is tested. During the testing process, the rotating table 2 can make the object to be tested rotate in the horizontal direction, so that the object to be tested can detect signals at different angles to make the test data more accurate. Under the dual action of the lifting member 7 and the rotating member 3, the object to be tested can be tested at different positions in the horizontal and vertical directions, which can meet the needs of testing the object to be tested at different positions, thereby helping to improve the accuracy of the detection.
[0030] At the same time, in this embodiment, a remote control module (not shown in the figure) is also provided on the base 1. The remote control module is electrically connected to the rotating member 3 and the lifting member 7, and can remotely control the lifting and rotation of the rotating table 2, which is simple, convenient and easy to operate.
[0031] The implementation principle of the anti-winding rotating platform in the embodiment of the present application is as follows: due to the setting of the slip ring 4, when the rotating table 2 rotates, since the inner ring 42 of the slip ring 4 is movable, when the line connects the inner ring 42 of the slip ring 4 to the communication port adapter module 5, the inner ring 42 of the slip ring 4 can rotate together with the rotating table 2, so that the connected line can also rotate together, which can avoid the external line connected to the communication port adapter module 5 from winding or entanglement when the object to be measured is rotated and measured, thereby avoiding the phenomenon of equipment pulling damage due to line winding.
[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
