Description

Technical Field

[0001] This application relates to the field of microwave antenna technology, and in particular to a millimeter-wave antenna testing device. Background Technology

[0002] A millimeter-wave antenna test bench is a device used to test and evaluate millimeter-wave antennas to ensure their performance and functionality meet specified requirements. A millimeter-wave test bench is typically a large piece of equipment composed of several different components. It generally includes the following main components:

[0003] Antenna: The millimeter-wave test bench requires the use of an antenna for testing to ensure that the antenna performance meets the requirements.

[0004] Signal source: The test bench needs to use a signal source to provide a suitable signal in order to test the antenna's receiving capability.

[0005] Signal analyzer: A signal analyzer can analyze the signals received by an antenna to check its performance parameters such as frequency and power.

[0006] Console: The console is the control center of the test bench, used to control the operation of the test bench and configure test parameters.

[0007] Stands and stand rotators: Stands and stand rotators are used to fix and rotate test samples to ensure test accuracy.

[0008] Regarding the aforementioned technologies, the testing device can only rotate the antenna and cannot adjust the angle between the antenna and the signal source in real time. When the angle between the antenna and the signal source is different, the strength and polarization of the received signal may be affected, which will lead to the test results being different from the actual situation. Summary of the Invention

[0009] In order to enable the antenna to be adjusted in angle with the signal source during the testing process and improve the accuracy of antenna testing, this application provides a millimeter-wave antenna testing device.

[0010] The millimeter-wave antenna testing device provided in this application adopts the following technical solution:

[0011] A millimeter-wave antenna testing device includes a support frame, a signal source, a signal analyzer, and a control console. The signal source, signal analyzer, and control console are all mounted on the support frame. A support plate is mounted on the support frame, and a support seat is mounted on the support plate. A curved track is formed along the circumference of the support seat. A support rod is mounted on the support seat, and a support platform is ball-hinged to the support rod. A clamping assembly for fixing the antenna to the support platform is mounted on the support platform. A swing rod is slidably connected to the support platform and is hinged to the support platform. A ball is hinged to the swing rod and is located within the curved track. A rotation assembly for driving the swing rod to rotate around the support platform is mounted on the support seat. A lifting assembly for driving the support platform to rise and fall is mounted on the support frame.

[0012] By adopting the above technical solution, the antenna is placed on the support platform, and then the clamping assembly fixes the antenna. The control console controls the signal source to transmit signals and controls the rotating assembly to drive the swing rod to rotate. The swing rod drives the control console to rotate. At the same time, as the ball moves along the curved track, the swing rod moves up and down during the rotation, pushing the support platform to swing up and down, so that the angle between the antenna and the signal source can be adjusted. Meanwhile, the control console controls the lifting assembly to drive the support plate to rise and fall. The support plate drives the support base and the support platform to rise and fall, realizing the adjustment of the distance between the signal source and the antenna. This makes the data of the antenna during the test closer to the data during actual use, improving the accuracy of the antenna test by the testing device.

[0013] Optionally, the rotating assembly includes a rotating sleeve rotatably mounted on the support rod. The support base is an annular column. A mounting plate is provided on the support plate, passing through the support base. A first motor is provided on the mounting plate, and a first gear is provided on the motor shaft of the first motor. A second gear is provided on the rotating sleeve, and the first gear and the second gear mesh with each other. A rotating rod is connected to the rotating sleeve, and a limiting sleeve is connected to the rotating rod. The limiting sleeve is fitted onto the swing rod.

[0014] By adopting the above technical solution, the first motor drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the rotating sleeve to rotate, and the rotating sleeve drives the rotating rod and the limiting sleeve to rotate, thereby realizing that the swing rod rotates around the support base, and thus realizing that the support platform can swing and rotate simultaneously.

[0015] Optionally, the support base is rotatably connected to the support plate, the support rod passes through the support base and is rotatably connected to the support plate, the support base is provided with a driven gear, the support plate is provided with a second motor, the second motor is provided with a driving gear, and the driving gear meshes with the driven gear.

[0016] By adopting the above technical solution, the second motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the support base to rotate, and when the support base rotates, the rolling ball moves relative to the curved track. The rolling ball drives the swing rod to move up and down, thereby realizing that the support platform only swings and does not rotate.

[0017] Optionally, the lifting assembly includes a reciprocating lead screw and a guide rod. One end of the support plate is fitted onto the reciprocating lead screw, and the other end of the support plate is fitted onto the guide rod. The nut of the reciprocating lead screw supports the support plate, and a third motor for driving the reciprocating lead screw to rotate is provided on the support frame.

[0018] By adopting the above technical solution, the third motor drives the reciprocating screw to rotate, the nut of the reciprocating screw rises and falls along the screw of the reciprocating screw and drives the support plate to rise and fall. The guide rod guides the rise and fall of the support plate, thereby realizing the rise and fall of the support platform, which facilitates the adjustment of the distance between the antenna and the signal source.

[0019] Optionally, the clamping assembly includes a first clamping block, a second clamping block, and two third clamping blocks. The first, second, and third clamping blocks are all slidably mounted on the support platform. The support platform has a hollow structure. The first clamping block is connected to an adjusting block, which is slidably mounted within the support platform. The adjusting block has an adjusting groove, and a first rack is disposed within the adjusting groove. An adjusting gear is rotatably mounted within the support platform, meshing with the first rack. The second clamping block is positioned opposite to the first clamping block and is connected to a second rack, which meshes with the adjusting gear. The two third clamping blocks are located between the first and second clamping blocks. Each third clamping block is hinged to an adjusting rod, and each of the two adjusting rods is hinged to one side of the adjusting rod. The control console is equipped with a rotating component for controlling the movement of the first clamping block.

[0020] By adopting the above technical solution, the antenna is placed between the first clamping block, the second clamping block, and the third clamping block. The rotating component drives the first clamping block to slide on the support platform and approach the antenna. The first clamping block drives the adjusting block to move, the adjusting block drives the first rack to move, the first rack drives the adjusting gear to rotate, the adjusting gear drives the second rack to move, and the second rack drives the second clamping block to move closer to the antenna. At the same time, the adjusting block drives the two adjusting rods to move, thereby enabling the two third clamping blocks to move closer to the antenna. When the first clamping block abuts against the antenna, the second and third clamping blocks abut against the antenna simultaneously. Only the first clamping block needs to be adjusted to fix the antenna, which is convenient for operation.

[0021] Optionally, the rotating component includes a rotating bolt, which is threadedly connected to the support platform and rotatably connected to the adjusting block.

[0022] By adopting the above technical solution, rotating the rotating bolt, as the rotating bolt extends into the support platform, the rotating bolt drives the first clamping block closer to the antenna.

[0023] Optionally, the first clamping block, the second clamping block, and the third clamping block are all provided with anti-slip pads.

[0024] By adopting the above technical solution, the antenna is secured, preventing it from falling off the support platform when swinging.

[0025] Optionally, the swing rod includes a first connecting rod and a second connecting rod. The first connecting rod is slidably connected to the control console. The limiting sleeve is sleeved on the first connecting rod. The second connecting rod is rotatably connected to the ball. The first connecting rod has a first fixing groove. The second connecting rod is threaded with a first fixing bolt. The first fixing bolt is threaded into the first fixing groove. The first connecting rod has a second fixing groove. The limiting sleeve has a threaded hole communicating with the second fixing groove. The threaded hole is threaded with a second fixing bolt. The second fixing bolt is threaded into the second fixing groove.

[0026] By adopting the above technical solution, the first fixing bolt is loosened to separate the first connecting rod from the second connecting rod, and then the second fixing bolt is threaded into the second fixing groove, so that when the first connecting rod rotates, it only drives the support platform to rotate.

[0027] Optionally, the first connecting rod and the second connecting rod are arranged perpendicular to each other.

[0028] By adopting the above technical solution, the torque on the rotating sleeve is reduced by the first connecting rod and the second connecting rod being perpendicular to each other, thereby reducing the power consumption of the first motor.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The control console controls the first, second, and third motors, enabling the support platform to lift, swing, rotate, and rotate while swinging. This allows for adjustment of the positional relationship between the signal source and the antenna, making the relative position of the antenna to the signal source during testing more similar to the actual position during use. Consequently, the test data is closer to the actual data, improving the accuracy of the antenna test.

[0031] 2. By rotating the rotating bolt, the first clamping block is moved closer to the antenna. As the first clamping block moves, the adjusting block moves, and the adjusting block moves the second clamping block and the two third clamping blocks closer to the antenna at the same time. This allows the first clamping block, the second clamping block, and the two third clamping blocks to clamp the antenna simultaneously, thus achieving rapid fixation of the antenna.

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0041] This application discloses a millimeter-wave antenna testing device.

[0042] like Figure 1 , Figure 2 and Figure 7 A millimeter-wave antenna testing device includes a support frame 1, a signal source 2, a signal analyzer 3, and a control console 4. The signal source 2, the signal analyzer 3, and the control console 4 are all mounted on the support frame 1. A support plate 5 is slidably mounted on the support frame 1. A lifting assembly 6 for raising and lowering the support plate 5 is mounted on the support frame 1. A support seat 7 is rotatably mounted on the support plate 5. The support seat 7 is an annular cylinder.

[0043] The support base 7 has a curved track 71 along its side, which is wavy. The support plate 5 has a support rod 72 that passes through the support base 7. The axis of the support rod 72 coincides with the axis of the support base 7. The support rod 72 is ball-hinged to a support platform 73, which is a cylindrical platform. The bottom of the support platform 73 has a groove 731 that runs radially along the support platform 73. A rotating shaft 732 is slidably connected in the groove 731. A swing rod 74 is hinged to the rotating shaft 732. A ball 75 is hinged to the end of the swing rod 74 away from the support platform 73. The ball 75 is located in the curved track 71. The support plate 5 has a rotating assembly 8 for driving the swing rod 74 to rotate around the support base 7. The support platform 73 has a clamping assembly 9 for fixing the antenna on the support platform 73.

[0044] like Figure 3 and Figure 4 A second motor 51 is provided on the support plate 5, and a driving gear 52 is provided on the second motor 51. A driven gear 53 is provided on the support base 7, and the driven gear 53 meshes with the passive gear.

[0045] When testing the antenna, the antenna is first placed on the support platform 73 and fixed on the support platform 73 with the clamping assembly 9. Then, the control console 4 controls the signal source 2 to transmit a signal. At the same time, the control console 4 controls the rotation assembly 8 and the lifting assembly 6 to start according to the actual use of the antenna. The lifting assembly 6 drives the support plate 5 to rise and fall, thereby adjusting the distance between the antenna on the support platform 73 and the signal source 2. The rotation assembly 8 controls the swing rod 74 to rotate. The swing rod 74 drives the ball 75 to move along the curved track 71. At the same time, the swing rod 74 drives the support platform 73 to swing up and down and rotate, thereby adjusting the angle between the antenna and the signal source 2. When the rotating component 8 stops and the second motor 51 starts, the second motor 51 drives the driving gear 52 to rotate, the driving gear 52 drives the driven gear 53 to rotate, the driven gear 53 drives the support base 7 to rotate, and the ball 75 moves relative to the curved track 71, so that the swing rod 74 drives the support platform 73 to swing but not rotate, which facilitates the adjustment of the positional relationship between the antenna and the signal source 2, making the relative position of the antenna and the signal source 2 during the test more similar to the relative position of the antenna and the signal source 2 during actual use, so that the data during the test can be closer to the data during actual use, and improve the accuracy of the test device for antenna testing.

[0046] like Figure 6 and Figure 7 The rotating assembly 8 includes a rotating sleeve 81 and a first motor 82. A mounting plate 83 is provided on the support plate 5, and the mounting plate 83 passes through the support base 7. The first motor 82 is mounted on the mounting plate 83. The rotating sleeve 81 is rotatably mounted on the support rod 72. A first gear 84 is provided on the first motor 82, and a second gear 85 is provided on the rotating sleeve 81. The first gear 84 and the second gear 85 mesh with each other. A rotating rod 86 is connected to the rotating sleeve 81, and a limiting sleeve 87 is connected to the rotating rod 86. The limiting sleeve 87 is sleeved on the swing rod 74.

[0047] The swing arm 74 includes a first connecting rod 741 and a second connecting rod 742. The first connecting rod 741 is hinged to the rotating shaft 732. A limiting sleeve 87 is sleeved on the first connecting rod 741. The first connecting rod 741 and the second connecting rod 742 are perpendicular to each other. A first fixing groove 7411 is opened at the bottom of the first connecting rod 741. A first fixing bolt 743 passes through the second connecting rod 742 and is threaded into the first fixing groove 7411. The second connecting rod 742 is rotatably connected to the ball 75. A second fixing groove 7412 is opened on the side of the first connecting rod 741. A threaded hole 871 is opened on the limiting sleeve 871. The threaded hole 871 communicates with the second fixing groove 7412. A second fixing bolt 744 is threaded into the threaded hole 871 and is threaded into the second fixing groove 7412.

[0048] like Figure 1The lifting assembly 6 includes a reciprocating screw 61 and a guide rod 62. Both the reciprocating screw 61 and the guide rod 62 are installed inside the support frame 1. One end of the support plate 5 is fitted onto the reciprocating screw 61, and the other end is fitted onto the guide rod 62. The nut of the reciprocating screw 61 supports the support plate 5. A third motor 63 is installed on the support frame 1, and the third motor 63 is connected to the screw of the reciprocating screw 61.

[0049] like Figure 5 , Figure 6 and Figure 7 The clamping assembly 9 includes a first clamping block 91, a second clamping block 92, and two third clamping blocks 93. The first clamping block 91 and the second clamping block 92 are arranged opposite each other, and the two third clamping blocks 93 are arranged opposite each other. The antenna is placed on the support platform 73, and the antenna is located between the first clamping block 91, the second clamping block 92, and the two third clamping blocks 93. The first clamping block 91, the second clamping block 92, and the two third clamping blocks 93 are all slidably arranged on the support platform 73. The first clamping block 91, the second clamping block 92, and the two third clamping blocks 93 are all provided with anti-slip pads 94. The support platform 73 has a hollow structure. An adjusting block 95 is connected to the support platform 73. The adjusting block 95 is slidably disposed within the support platform 73. An adjusting groove 951 is formed at the end of the adjusting block 95 near the second clamping block 92. A first rack 96 is disposed on the top wall of the adjusting groove 951. An adjusting gear 97 is rotatably disposed within the support platform 73. The first rack 96 meshes with the adjusting gear 97. One end of the second clamping block 92 is located within the support platform 73. The end of the second clamping block 92 extending into the support platform 73 is connected to a second rack 98. The second rack 98 meshes with the adjusting gear 97. The first rack 96 is located above the second rack 98. Adjusting rods 99 are hinged to both sides of the adjusting block 95. Each of the two adjusting rods 99 is hinged to a third clamping block 93. A rotating component 910 is provided on the control console 4 for controlling the movement of the first clamping block 91. The rotating component 910 includes a rotating bolt 9101, which is inserted into the support platform 73 and threadedly connected thereto. One end of the rotating bolt 9101 inserted into the support platform 73 is rotatably connected to the adjusting block 95.

[0050] The antenna is placed on the support platform 73, and then the rotating bolt 9101 is rotated. Rotating the bolt 9101 causes the first clamping block 91 to slide on the support platform 73 and move closer to the antenna. The first clamping block 91 causes the adjusting block 95 to move, the adjusting block 95 causes the first rack 96 to move, the first rack 96 causes the adjusting gear 97 to rotate, the adjusting gear 97 causes the second rack 98 to move, and the second rack 98 causes the second clamping block 92 to move closer to the antenna. At the same time, the adjusting block 95 causes the two adjusting rods 99 to move, thereby bringing the two third clamping blocks 93 closer to the antenna. When the first clamping block 91 contacts the antenna, the second clamping block 92 and the third clamping block 93 simultaneously contact the antenna, so that the antenna can be quickly fixed.

[0051] After the antenna is fixed on the support platform 73, the control console 4 controls the signal source 2 to transmit a signal and starts the third motor 63 to drive the reciprocating screw 61 to rotate. The nut of the reciprocating screw 61 moves up and down along the screw of the reciprocating screw 61 and drives the support plate 5 to move up and down. The guide rod 62 guides the movement of the support plate 5, thereby realizing the movement of the support platform 73 and adjusting the distance between the antenna and the signal source 2.

[0052] The control console 4 starts the first motor 82, which drives the first gear 84 to rotate. The first gear 84 drives the second gear 85 to rotate, and the second gear 85 drives the rotating sleeve 81 to rotate. The rotating sleeve 81 drives the rotating rod 86 and the limiting sleeve 87 to rotate, thereby realizing that the swing rod 74 rotates around the support base 7, and thus the support platform 73 can swing and rotate simultaneously.

[0053] When only antenna rotation needs to be controlled and not oscillation, loosen the first fixing bolt 743 to separate the first connecting rod 741 from the second connecting rod 742, then tighten the second fixing bolt 744 to fix the limiting sleeve 87 and the first connecting rod 741. Then start the first motor 82 to make the first connecting rod 741 drive the support platform 73 and the antenna to rotate. This allows the support platform 73 to change the positional relationship between the antenna and the signal source 2 through lifting, oscillation, rotation, and rotation and oscillation. The signal analyzer 3 analyzes the signal received by the antenna in real time to check its performance parameters such as frequency and power, making the relative position of the antenna and the signal source 2 during the test more similar to the relative position of the antenna and the signal source 2 in actual use. This makes the test data closer to the actual use data, improving the accuracy of the antenna test by the testing device.

[0054] The implementation principle of this application embodiment is as follows: The control console 4 controls the first motor 82, the second motor 51, and the third motor 63. The first motor 82 drives the rotating sleeve 81 to rotate, the rotating sleeve 81 drives the limiting sleeve 87 to rotate, and the limiting sleeve 87 drives the first connecting rod 741 to rotate, thereby realizing the swinging motion of the support platform 73 during rotation. Separating the first connecting rod 741 and the second connecting rod 742 allows the first connecting rod 741 to drive the support platform 73 to rotate independently. The second motor 51 drives the support base 7 to rotate, and the ball 75 moves relative to the curved track 71, thereby realizing the swinging motion of the support platform 73 independently. The third motor 63 drives the reciprocating screw 61 to rotate, thereby realizing the lifting and lowering of the support plate 5, and thus the lifting and lowering of the support platform 73. By realizing the lifting, swinging, rotating, and rotating-swinging movements of the support platform 73, the positional relationship between the signal source 2 and the antenna can be adjusted, making the relative position of the antenna and the signal source 2 during the test more similar to the relative position of the antenna and the signal source 2 during actual use. This makes the test data closer to the actual use data, improving the accuracy of the test device in antenna testing.

[0055] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
