[0036] First embodiment

[0037] See also Figure 1 In this embodiment, a feed source switching device 10 is provided, which is applied in wireless testing to realize convenient and fast switching of feed sources 310 of different types and different arrangement arrays, thereby improving the efficiency of wireless testing.

[0038] In this example, see Figure 1 The feed switching device 10 includes a base 100, a rotating assembly 200 and a plurality of feed assemblies 300. The base 100 includes a bearing body 110 and an adjusting body 120. The adjusting body 120 is flippably disposed on the bearing body 110, and the adjusting body 120 has a mounting surface 121. When the adjusting body 120 is flipped relative to the bearing body 110, the angle between the mounting surface 121 and the horizontal plane is adjusted. The rotating assembly 200 is rotatably disposed on the mounting surface 121. A plurality of feed assemblies 300 are disposed on the rotating assembly 200 along a circular path; each feed assembly 300 has at least one feed 310, and the feed 310 in the plurality of feed assemblies 300 are all oriented toward a side away from the center of the circular path.

[0039] As described above, in the feed switching device 10, since a plurality of feed assemblies 300 are arranged on the rotating assembly 200, and at least one feed 310 is arranged in each feed assembly 300, that is to say, feeds 310 of different types and different arrangements can be arranged on the rotating assembly 200. Based on this, the switching of feeds 310 of different types or different arrangements can be easily completed by rotating the rotating assembly 200 relative to the adjusting body 120. At the same time, the feed 310 can be placed in a predetermined position by flipping the adjusting body 120 relative to the carrying body 110, and the pitch angle of the feed 310 can be adjusted. In other words, the feed switching device 10 provided in this embodiment can not only conveniently and quickly complete the switching of feeds 310 of different types or different arrangements, but also adjust the position and pitch angle of the feed 310; at the same time, the feed switching device 10 has a simple structure and is easy to maintain.

[0040] It is worth noting that, since the adjustment body 120 in the base 100 is in an inclined state, the feed assembly 300 in the working state can be placed in a high position, while the feed assembly 300 not in the working state can be placed in a low position, so that the feed assembly 300 not in the working state can be kept away from the parallel wave zone, which can reduce or avoid the influence of the feed assembly 300 not in the working state on the reflected parallel wave, and is more suitable for the working principle of the compact field; in addition, the multiple feed assemblies 300 are all facing the side away from the center of the circular path, so that the feed assembly 300 not in the working state is oriented away from the direction of the reflecting surface. Compared with the prior art of directing multiple feed sources 310 in the same direction, the feed switching device 10 in this embodiment can improve the quality of the quiet zone.

[0041] In addition, by arranging multiple feed assemblies 300 in a flat manner on the adjustment body 120, the vertical distance between the feed assembly 300 in the working position and the installation site can be reduced. When the feed switching device 10 is used in a radio wave darkroom, there is no need to dig a pit in the radio wave darkroom to place the equipment, which can enhance the overall applicability of the feed switching device 10.

[0042] Optionally, in this embodiment, the adjusting body 120 and the carrying body 110 are both in the shape of a plate, and one side of the adjusting body 120 is hinged to one side of the carrying body 110, so that the adjusting body 120 can be flipped relative to the carrying body 110. It is worth noting that the hinge between the adjusting body 120 and the carrying body 110 has a certain damping, so that after the adjusting body 120 is flipped relative to the carrying body 110, the position of the adjusting body 120 can be locked, thereby ensuring that the mounting surface 121 is maintained at a predetermined angle.

[0043] It should be understood that in other embodiments, a pad for locking the adjusting body 120 may also be provided between the adjusting body 120 and the carrying body 110 , so that the adjusting body 120 can be locked by adjusting the position of the pad after the adjustment is completed.

[0044] In this embodiment, the rotating assembly 200 includes a turntable 210 and a driving assembly 220. The turntable 210 is rotatably disposed on the mounting surface 121. The driving assembly 220 is disposed on the adjusting body 120. The driving assembly 220 is transmission-connected to the turntable 210 to drive the turntable 210 to rotate on the mounting surface 121. Multiple feed assemblies 300 are disposed on the turntable 210.

[0045] Optionally, see Figure 1 and Figure 2 The driving assembly 220 includes a driving motor 221 and a gear ring transmission wheel 222. The driving motor 221 and the gear ring transmission wheel 222 are in transmission cooperation. The gear ring transmission wheel 222 and the turntable 210 are in transmission cooperation. The driving motor 221 drives the turntable 210 to rotate through the gear ring transmission wheel 222. The driving motor 221 can be a servo motor or a stepping motor; the gear ring transmission wheel 222 can be a high-precision gear ring transmission wheel 222, thereby accurately completing the position adjustment of the feed assembly 300, ensuring that the feed assembly 300 can be placed at a specified position after following the turntable 210 to rotate.

[0046] Furthermore, in order to accurately adjust the pitch angle of the feed assembly 300, in the present embodiment, the feed assembly 300 includes a supporting seat 320, an adjustment assembly 330 and a plurality of feed sources 310; the supporting seat 320 is disposed on the rotating assembly 200, and the plurality of feed sources 310 are disposed on the adjustment assembly 330; the adjustment assembly 330 can be movably disposed on the supporting seat 320 for adjusting the pitch angle of the feed source 310.

[0047] That is to say, the adjustment of the pitch angle of the feed source 310 achieved by flipping the adjustment body 120 relative to the supporting body 110 can be regarded as a coarse adjustment, and the movement of the adjustment component 330 relative to the supporting seat 320 can further adjust the pitch angle of the feed source 310 more accurately to ensure that the pitch angle of the feed source 310 meets actual needs.

[0048] Please refer to Figure 1 and Figure 3The adjustment component 330 includes a mounting body 331, an adjustment portion 332 and a fixed body 333; a plurality of feed sources 310 are arranged on the mounting body 331; the adjustment portion 332 is arranged on the mounting body 331, and a slide groove 3321 arranged along an arc path is provided on the adjustment portion 332; the fixed body 333 is fixed on the bearing seat 320, and is arranged in the slide groove 3321; the adjustment portion 332 can move relative to the fixed body 333 so that the fixed body 333 moves in the slide groove 3321, and the mounting body 331 drives the feed source 310 to adjust the pitch angle.

[0049] The mounting body 331 has a plane for mounting the feed source 310, and the adjusting parts 332 are arranged on both sides of the mounting body 331, so that the plane for mounting the feed source 310 on the mounting body 331 is tilted upward. When the adjusting part 332 moves relative to the fixed body 333, the fixed body 333 moves in the slide groove 3321, and the plane of the mounting body 331 for mounting the feed source 310 is in a flipped state, thereby realizing further adjustment of the pitch angle of the feed source 310.

[0050] It is worth noting that the fixing body 333 is columnar, and there is a certain damping between the fixing body 333 and the slide slot 3321 to ensure that the adjustment portion 332 can maintain position stability after moving relative to the fixing body 333 .

[0051] In addition, in order to facilitate the driving of the adjustment part 332 to move relative to the fixed body 333, a supporting part 334 is also provided on the adjustment part 332. The support seat 320 is provided with a fixed part 335 and an adjustment member 336. The adjustment member 336 is movably provided on the fixed part 335, and the supporting part 334 is provided on the moving path of the adjustment member 336; the adjustment member 336 can drive the supporting part 334 to move, so that the supporting part 334 drives the adjustment part 332 to move relative to the fixed body 333. In other words, the adjustment member 336 can be moved so that the adjustment member 336 pushes the supporting part 334, thereby realizing the driving of the adjustment part 332.

[0052] Optionally, in order to improve the adjustment accuracy, the adjustment member 336 can be provided on the fixed part 335 by a threaded connection, that is, the adjustment member 336 can be moved relative to the fixed part 335 by screwing the adjustment member 336 to achieve fine adjustment of the adjustment part 332.

[0053] It is worth noting that when the adjusting member 336 is screwed into the fixing portion 335, the adjusting member 336 can push the supporting portion 334 to move, thereby realizing the driving of the adjusting portion 332; and when the adjusting member 336 is screwed out of the fixing portion 335, the adjusting member 336 is disengaged from the supporting portion 334, and the adjusting member 336 only needs to be screwed to the specified position to realize the movement of the adjusting portion 332 manually.

[0054] In this embodiment, please refer to Figure 1 and Figure 4 In order to facilitate installation and adjustment and increase the adaptability of the system, a connecting piece 400 is also provided on the rotating assembly 200, and a waist-shaped hole 410 is opened on the connecting piece 400; the waist-shaped hole 410 is for the fixing piece to pass through to fix the connecting piece 400 on the rotating assembly 200; the feed assembly 300 is connected to the rotating assembly 200 through the connecting piece 400. Among them, the fixing piece can be a bolt, etc. The fixing piece passes through the waist-shaped hole 410 and is connected to the turntable 210, so that the fixing piece 400 can be fixed. By adjusting the position of the fixing piece in the waist-shaped hole 410 and adjusting the placement angle of the waist-shaped hole 410, the position of the connecting piece 400 on the turntable 210 can be adjusted. When the position of the connecting piece 400 is adjustable, the position of the feed assembly 300 as a whole on the turntable 210 can be adjusted.

[0055] It is worth noting that, generally, during the installation phase of the feed assembly 300, the position of the feed assembly 300 on the turntable 210 is adjusted by the connector 400. After the position of the feed assembly 300 is adjusted during the installation phase, the feed assembly 300 can be directly put into use; and during use, the connector 400 may not be adjusted if it is not necessary. Among them, by making the position of the connector 400 adjustable, during the installation phase, it is possible to ensure that the problem of low installation accuracy of the feed 310 caused by processing errors and assembly gaps is eliminated, thereby improving the installation positioning accuracy of the feed assembly 300.

[0056] In this embodiment, a mounting hole 321 is provided on the feed assembly 300, and the connector 400 is embedded in the mounting hole 321. Specifically, a mounting hole 321 is provided at the bottom of the bearing seat 320, and the connector 400 is embedded in the mounting hole 321.

[0057] Based on the feed switching device 10 provided above, the feed 310 can be adjusted by flipping the adjusting body 120 relative to the bearing body 110 to achieve preliminary position adjustment of the feed 310, so as to roughly place the feed 310 at the designated position. Then the switching of the designated feed 310 can be achieved by rotating the turntable 210. In addition, the position adjustment of the feed assembly 300 as a whole on the turntable 210 can be achieved by adjusting the position of the connecting member 400 on the turntable 210. Finally, the position positioning of the abutting portion 334 can be achieved by moving the adjusting member 336 relative to the fixed portion 335, and then the pitch angle of the feed 310 can be finely adjusted by moving the adjusting portion 332 relative to the fixed body 333. Based on this, fast switching of feeds 310 of different types and different arrangement arrays can be achieved, and precise adjustment of multiple degrees of freedom such as the pitch angle, azimuth and yaw of the feed 310 can also be achieved.

[0058] In this embodiment, the feed switching device 10 further includes an adjustable antenna fixture 500, which is disposed on the bearing seat 320, and the feed source 310 is clamped and fixed on the adjustable antenna fixture 500. The adjustable antenna fixture 500 has a motor, which can drive the feed source 310 to rotate, so as to achieve the purpose of switching the polarization of the feed source 310.

[0059] In summary, in the feed switching device 10, since a plurality of feed assemblies 300 are arranged on the rotating assembly 200, and at least one feed 310 is arranged in each feed assembly 300, that is to say, feeds 310 of different types and different arrangements can be arranged on the rotating assembly 200. Based on this, the switching of feeds 310 of different types or different arrangements can be easily completed by rotating the rotating assembly 200 relative to the adjusting body 120. At the same time, the feed 310 can be placed in a predetermined position by flipping the adjusting body 120 relative to the carrying body 110, and the pitch angle of the feed 310 can be adjusted. In other words, the feed switching device 10 provided in this embodiment can not only conveniently and quickly complete the switching of feeds 310 of different types or different arrangements, but also can realize the adjustment of the position and pitch angle of the feed 310; at the same time, the feed switching device 10 has a simple structure and is easy to maintain.

[0060] Second embodiment

[0061] See also Figure 5 In this embodiment, a reflector antenna 11 is provided. The reflector antenna 11 adopts the feed switching device 10 in the above-mentioned first embodiment. Based on this, the wireless testing system can realize convenient and fast switching of feed sources 310 of different types and different arrangements, thereby improving the efficiency of wireless testing.

[0062] In this embodiment, the reflector antenna 11 further includes a reflector 12, which has a reflector surface for reflecting electromagnetic signals, and can reflect the electromagnetic signal emitted by the feed source 310 into a plane wave signal. In this embodiment, the feed source switching device 10 and the reflector 12 are arranged at intervals, and the reflector surface in the reflector 12 is arranged toward the feed source switching device 10, and at least one feed component 300 in the feed source switching device 10 is arranged toward the reflector 12.

[0063] Further, in the present embodiment, the opening of the angle formed by the adjusting body 120 and the carrying body 110 is arranged toward the reflecting device 12, so that the feed assembly 300 on the adjusting body 120 that is farther from the carrying body 110 faces the reflecting device 12. In other words, when the feed switching device 10 is placed on a carrying surface such as the ground, since the adjusting body 120 forms an angle relative to the horizontal plane, that is, the adjusting body 120 is in an inclined state, the heights of the feed assemblies 300 on the adjusting body 120 are different. In the present embodiment, the feed assembly 300 that is farther from the carrying body 110 is arranged toward the reflecting device 12, so that the higher feed assembly 300 on the adjusting body 120 is arranged toward the reflecting device 12, so that the feed assembly 300 in the working state is in a high position, and the feed assembly 300 that is not in the working state is in a low position, so that the feed assembly 300 that is not in the working state can be kept away from the parallel wave zone, which is more suitable for the working principle of the compact field.

[0064] It should be understood that in other embodiments, the lower feed assembly 300 may also be disposed toward the reflection device 12, such as Figure 6 .

[0065] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
