[0033] First embodiment
[0034] See also Figure 1 In this embodiment, a turntable 10 is provided, which can be applied to a wireless test system and used to carry a device under test. It is worth noting that the turntable 10 can also be used to carry a device connected to the device under test, and improve the technical problem of inconvenient arrangement of electronic equipment connected to the device under test in the prior art.
[0035] Please refer to Figure 1 and Figure 2 The turntable 10 includes a motion structure 100, a first carrier body 200 and a second carrier body 300. The first carrier body 200 is connected to the motion structure 100, and the motion structure 100 is used to drive the first carrier body 200 to move. The second carrier body 300 is arranged above the first carrier body 200, and a receiving space 201 is formed between the second carrier body 300 and the first carrier body 200; the second carrier body 300 is used to carry the device under test, and the receiving space 201 is used to accommodate the device connected to the device under test. When the moving component drives the first carrier body 200 to move, the second carrier body 300 can move with the first carrier body 200, thereby achieving the purpose of driving the device under test on the second carrier body 300 to move.
[0036] It should be noted that the device includes but is not limited to electronic components such as a power supply unit, a control unit, and a link box connected to the device under test; of course, the device can also be a non-electronic component such as a liquid cooling tube.
[0037] As described above, in the turntable 10, the device under test can be placed on the second carrier body 300, and the devices connected to the device under test, such as the power supply unit, the control unit, and the link box, can be arranged in the accommodating space 201, that is, the devices can be arranged on the first carrier body 200 below the second carrier body 300. On the one hand, the second carrier body 300 can shield the device to prevent the device from affecting the test quiet zone and ensure that the test operation is carried out stably; on the other hand, the distance between the device and the device under test is shortened, the length of the connecting cable can be shortened, the connection between the device and the device under test is convenient, and the loss can also be reduced for the radio frequency cable. Based on this, the turntable 10 provided in this embodiment can improve the technical problem of inconvenient arrangement of electronic equipment connected to the device under test in the prior art.
[0038] It should be noted that in Figure 1 In the example, the number of the first carrier body 200 is one, thereby forming an accommodation space 201 between the first carrier body 200 and the second carrier body 300. It should be understood that in other embodiments of the present application, the first carrier body 200 may also be provided in plurality, and the plurality of first carrier bodies 200 are stacked in the vertical direction between the second carrier body 300 and the motion structure 100; at the same time, an accommodation space 201 is also formed between two adjacent first carrier bodies 200, thereby forming a plurality of accommodation spaces 201, which can accommodate more devices.
[0039] It is worth noting that, in the case of setting a plurality of first bearing bodies 200, the shapes and structures of the plurality of first bearing bodies 200 may not be completely the same, that is, the arrangement of the plurality of first bearing bodies 200 may be expressed in a variety of ways. For example, the plurality of first bearing bodies 200 have the same shape and structure, and the plurality of first bearing bodies 200 are stacked in the vertical direction between the second bearing body 300 and the motion structure 100. For another example, the shapes and structures of some first bearing bodies 200 are the same, while the shapes and structures of other first bearing bodies 200 are different; and the plurality of first bearing bodies 200 are arranged in a vertical direction, at this time, the volume of the accommodation space 201 formed between two adjacent first bearing bodies 200 is different from the volume of other accommodation spaces 201. For another example, the shapes and structures of the plurality of first bearing bodies 200 are all different.
[0040] Furthermore, in this embodiment, a through hole 301 is provided on the second carrier body 300, and the through hole 301 is used for the connection line between the device and the device under test to pass through. By providing the through hole 301, the connection line between the device and the device under test can directly pass through the through hole 301 to achieve the purpose of passing through the second carrier body 300, further shortening the length of the connection line between the device under test and the device, saving space, and reducing the loss for the RF cable.
[0041] In this embodiment, the turntable 10 further includes a supporting assembly 210, which is detachably connected to the first bearing body 200 and surrounds the outer periphery of the first bearing body 200; the supporting assembly 210 is used to lay absorbing materials. After the tested object and the device are placed and assembled on the turntable 10, the supporting assembly 210 can be installed on the first bearing body 200, and absorbing materials can be laid on the supporting assembly 210, which can reduce the reflection of electromagnetic waves and improve the accuracy of wireless testing operations.
[0042] Optionally, the supporting assembly 210 includes a plurality of supporting plates 220, which are arranged around the first bearing body 200, and the plurality of supporting plates 220 are detachably connected to the first bearing body 200. That is to say, in this embodiment, the supporting assembly 210 is arranged on the periphery of the first bearing body 200 in a split manner, and can be disassembled and installed one by one, which reduces the difficulty of disassembly and assembly, and can also reduce the volume when disassembled, reduce the occupied area, and facilitate transportation and storage.
[0043] It should be understood that in other embodiments of the present application, the supporting assembly 210 may also be provided in an integrated manner, that is, the supporting assembly 210 is annular in shape as a whole and can be provided on the periphery of the first supporting body 200 to facilitate the laying of the absorbing material.
[0044] In order to facilitate the assembly and disassembly of the support plate 220, a buckle 221 is provided on one side of the support plate 220, and a buckle assembly (not shown) adapted to the buckle 221 is provided on the first load-bearing body 200, and the buckle 221 is detachably connected to the buckle assembly. Through the cooperation between the buckle 221 and the buckle assembly, the difficulty of assembling the support plate 220 to the first load-bearing body 200 can be reduced. When the support plate 220 needs to be assembled, the buckle 221 is attached to the buckle assembly to complete the assembly. When disassembly is required, the buckle 221 can be directly taken out.
[0045] Optionally, in this embodiment, please refer to Figure 1 and Figure 3The first carrier body 200 is provided with a slot 202, and the snap-fit assembly includes a snap-fitting portion 203 disposed in the slot 202; the buckle 221 is provided with a groove 222 adapted to the snap-fitting portion 203; the buckle 221 extends into the slot 202, and the groove 222 cooperates with the snap-fitting portion 203. The slot 202 is provided on the side of the first carrier body 200 facing the second carrier body 300, that is, the slot 202 is provided on the upper side of the first carrier body 200. When assembling the support plate 220, the buckle 221 of the support plate 220 is first extended into the slot 202, and the groove 222 corresponds to the snap-fitting portion 203. After the snap-fitting portion 203 is installed in the groove 222, the support plate 220 is rotated to a horizontal position. Due to the cooperation between the snap-fitting portion 203 and the groove 222, when the buckle 221 abuts against the bottom wall of the slot 202, the assembly of the support plate 220 can be realized. Similarly, when removing the support plate 220 , the support plate 220 is rotated upward, and the clamping portion 203 is withdrawn from the groove 222 , and the support plate 220 can be removed.
[0046] In this embodiment, there is a gap between two adjacent support plates 220. On the one hand, the gap facilitates the removal of the support plates 220; on the other hand, interference between the two adjacent support plates 220 can also be avoided.
[0047] In this embodiment, the second carrier body 300 includes a carrier part 320 and a support part 310; the support part 310 is arranged below the carrier part 320, and the carrier part 320 is used to carry the device under test; a receiving space 201 is formed between the carrier part 320 and the first carrier body 200. The support part 310 is used to support the carrier part 320 to ensure that the carrier part 320 can stably carry the device under test; at the same time, the arrangement of the support part 310 can form a receiving space 201 between the carrier part 320 and the first carrier body 200, which is convenient for accommodating the device. Among them, the support part 310 is a plurality of columnar structures to stably support the carrier part 320.
[0048] In this example, see Figure 2 The motion structure 100 includes a translation assembly 110 and a rotation assembly 120; the translation assembly 110 is arranged on the rotation assembly 120, and the rotation assembly 120 is used to drive the translation assembly 110 to rotate. The first bearing body 200 is arranged on the translation assembly 110 and can rotate with the translation assembly 110; the translation assembly 110 is used to drive the first bearing body 200 to translate. Among them, the translation assembly 110 can drive the first bearing body 200 to move in two directions perpendicular to each other, and the rotation assembly 120 can drive the first bearing body 200 to rotate, thereby realizing wireless testing of multiple orientations and multiple positions of the tested object.
[0049] In summary, in the turntable 10, the device under test can be placed on the second bearing body 300, and the devices connected to the device under test, such as the power supply unit, the control unit and the link box, can be arranged in the accommodating space 201, that is, the devices can be arranged on the first bearing body 200 below the second bearing body 300. On the one hand, the second bearing body 300 can shield the device to prevent the device from affecting the test quiet zone and ensure that the test operation is carried out stably; on the other hand, the distance between the device and the device under test is shortened, the length of the connecting cable can be shortened, the device and the device under test are conveniently connected, and the loss can also be reduced for the radio frequency cable.
