Description

Technical Field

[0001] This utility model relates to the field of antenna testing technology, and in particular to an antenna support device for anechoic chamber testing. Background Technology

[0002] Antenna support devices for anechoic chamber testing typically refer to anechoic chamber turntables, which are key equipment in electromagnetic compatibility testing and wireless device certification. They enable precise antenna positioning and multi-dimensional adjustment, allowing for accurate positioning tests of antenna receiving performance.

[0003] Before conducting antenna testing, the antenna under test needs to be fixed on the top of the anechoic chamber turntable. Currently, fixing the antenna is quite cumbersome and cannot quickly fix antennas of different specifications, resulting in low efficiency.

[0004] Therefore, to address the above issues, an antenna support device for anechoic chamber testing can be designed to quickly fix antennas of different specifications, effectively improving the efficiency of antenna assembly and disassembly. Utility Model Content

[0005] To overcome the current problem that fixing antennas on an anechoic chamber turntable is cumbersome, cannot quickly fix antennas of different specifications, and is inefficient.

[0006] The technical solution of this utility model is as follows: an antenna support device for anechoic chamber testing, comprising a base, a placement platform, an adjustment plate, a support assembly, a rotation assembly, an installation assembly, and an adjustment assembly. The upper end of the base is sequentially provided with the support assembly, rotation assembly, and installation assembly from bottom to top. The adjustment assembly is located inside the installation assembly. The placement platform is located at the upper end of the installation assembly. The surface of the placement platform has four sets of through-slots, which are evenly arranged circumferentially around the axis of the placement platform. The upper end of the placement platform has four sets of clamping blocks, which are slidably connected to the four sets of slots. One end of the slider has a V-groove, and the other end of the slider is fixedly mounted with a connecting rod that passes through the slot. The adjustment plate is rotatably connected to the lower end of the placement platform. The surface of the adjustment plate has four sets of arc-shaped slots, which are evenly arranged circumferentially around the axis of the placement platform. The connecting rod passes through the arc-shaped slots. An internal threaded bracket is fixedly mounted on the periphery of the adjustment plate, and the internal thread of the internal threaded bracket is connected with a rubber-head set screw.

[0007] Preferably, a support component is used to support and install the rotating component, and the rotating component is used to support and install the mounting component, which can also drive the mounting component to rotate. The mounting component is used to support and install the placement platform. An adjustment component is used to adjust the angle of the placement platform. The placement platform is used to place the antenna under test. An internal threaded bracket is used to rotate the adjustment disc, which in turn drives the connecting rod to slide along the slide groove through the arc groove. This allows four sets of clamping blocks to slide along the slide groove, facilitating the clamping and fixing of antennas under test of different specifications. The V-groove design at one end of the clamping block allows the clamping block to fit more closely to the periphery of the antenna under test. By rotating the rubber head screw inside the internal threaded bracket, one end of the rubber head screw can press against the placement platform, thereby locking the adjustment disc.

[0008] Preferably, the support assembly includes a support sleeve, a sliding sleeve, and a telescopic rod. The support sleeve is fixedly installed on the upper end of the base, the sliding sleeve is slidably connected to the periphery of the support sleeve, and the telescopic rod is fixedly installed inside the support sleeve, with the output end of the telescopic rod fixedly connected to the sliding sleeve.

[0009] Preferably, the rotating assembly includes a first motor and a support plate. The first motor is fixedly installed inside the sliding sleeve, and the output shaft of the first motor passes through the sliding sleeve and is rotatably connected to the sliding sleeve. The support plate is fixedly installed on the upper end of the output shaft of the first motor.

[0010] Preferably, the rotating assembly includes an annular guide rail and a guide frame. The annular guide rail is fixedly installed on the upper end of the sliding sleeve, and the guide frame is fixedly installed on the lower end of the support plate. The guide frame is rotatably connected to the annular guide rail.

[0011] Preferably, the mounting assembly includes a mounting bracket, a mounting shaft, and a connecting block. The mounting bracket is fixedly mounted on the upper end of the support plate, the mounting shaft is rotatably connected to the inside of the mounting bracket, the connecting block is fixedly mounted on the periphery of the mounting shaft, and the placement platform is fixedly mounted on the upper end of the connecting block.

[0012] Preferably, the adjusting assembly includes a worm gear and a worm. The worm gear is fixedly installed on the periphery of the mounting shaft, and the worm is rotatably connected to the inside of the mounting bracket, with the worm gear meshing with the worm.

[0013] Preferably, the adjustment assembly includes a second motor, transmission wheels, and a transmission belt. The second motor is fixedly installed inside the mounting bracket, and the output shaft of the second motor is rotatably connected to the mounting bracket. A set of transmission wheels is fixedly installed around the output shaft of the second motor and around the worm gear, and the transmission belt is located around the two sets of transmission wheels.

[0014] The beneficial effects of this utility model are:

[0015] 1. When fixing the antenna under test, first loosen the rubber head screw, turn the adjustment plate to rotate, and drive the connecting rod to slide along the slide groove through the arc groove. This will cause the four sets of clamping blocks to slide away from the axis of the placement platform along the slide groove. Place the antenna under test between the four sets of clamping blocks, and then turn the adjustment plate in the opposite direction to drive the four sets of clamping blocks to slide along the slide groove towards the axis of the placement platform. The four sets of clamping blocks will clamp and fix the antenna under test. The V-groove design at one end of the clamping block can make the clamping block fit more closely to the outer periphery of the antenna under test, which can easily clamp and fix antennas of different specifications. Then, rotate the rubber head screw inside the internal thread bracket to make one end of the rubber head screw press against the placement platform and lock the adjustment plate, ensuring that the antenna under test can be stably clamped. This is convenient and quick, without the need for complicated disassembly and assembly of bolts and other fasteners.

The surface of the adjusting plate 3 is provided with four sets of arc-shaped grooves 301, which are evenly arranged circumferentially around the axis of the placement platform 2. The connecting rod 204 passes through the arc-shaped grooves 301, and the outer periphery of the adjusting plate 3 is fixed. An internal threaded bracket 302 is installed, with a rubber head screw 303 connected to its internal thread. A support assembly supports and installs the rotating assembly, which in turn supports and installs the mounting assembly and allows it to rotate. The mounting assembly supports and installs the placement platform 2. An adjustment assembly allows for angle adjustment of the placement platform 2. The placement platform 2 allows for the placement of the antenna under test. The internal threaded bracket 302 allows the adjustment disc 3 to rotate, causing the connecting rod 204 to slide along the slide groove 201 via the arc groove 301. This allows four sets of clamping blocks 202 to slide along the slide groove 201, facilitating the clamping and fixing of antennas of different specifications. The V-groove 203 at one end of the clamping block 202 allows for a closer fit with the outer periphery of the antenna under test. Rotating the rubber head screw 303 within the internal threaded bracket 302 causes one end of the rubber head screw 303 to press against the placement platform 2, thereby locking the adjustment disc 3.

[0024] Please see Figure 1 and Figure 2In this embodiment, the support assembly includes a support sleeve 401, a sliding sleeve 402, and a telescopic rod 403. The support sleeve 401 is fixedly installed on the upper end of the base 1, the sliding sleeve 402 is slidably connected to the periphery of the support sleeve 401, and the telescopic rod 403 is fixedly installed inside the support sleeve 401, with its output end fixedly connected to the sliding sleeve 402. The sliding sleeve 402 is installed by setting the support sleeve 401, and the sliding sleeve 402 is installed by setting a bottom rotating assembly. The telescopic rod 403 can drive the sliding sleeve 402 to slide up and down around the support sleeve 401, thereby adjusting the height of the placement platform 2. The rotating assembly includes a first motor 501 and a support plate 502, with the first motor 501 fixedly installed inside the sliding sleeve 402. The output shaft of the first motor 501 passes through the sliding sleeve 402 and is rotatably connected to the sliding sleeve 402. The support plate 502 is fixedly installed on the upper end of the output shaft of the first motor 501. The rotating assembly includes an annular guide rail 503 and a guide frame 504.

The placement platform 2 is supported and mounted by the connecting block 603, and the mounting shaft 602 and the connecting block 603 are supported and mounted by the mounting bracket 601. The adjusting assembly includes a worm gear 701 and a worm 702. The worm gear 701 is fixedly mounted on the periphery of the mounting shaft 602, and the worm 702 is rotatably connected to the inside of the mounting bracket 601. The worm gear 701 meshes with the worm 702. The adjusting assembly includes a second motor 7. 03. Transmission wheel 704 and transmission belt 705: The second motor 703 is fixedly installed inside the mounting bracket 601. The output shaft of the second motor 703 is rotatably connected to the mounting bracket 601. A set of transmission wheels 704 are fixedly installed on the periphery of the output shaft of the second motor 703 and the periphery of the worm 702. The transmission belt 705 is set on the periphery of the two sets of transmission wheels 704. By setting the second motor 703, it can drive one set of transmission wheels 704 to rotate, thereby transmitting the rotation to the worm 702 through the transmission belt 705 in conjunction with the other set of transmission wheels 704. By setting the worm 702 to rotate, it can drive the worm wheel 701 to rotate, thereby driving the mounting shaft 602 to rotate and adjusting the angle of the placement platform 2. The worm wheel 701 and worm 702 have self-locking properties, which can ensure the stability of the angle adjustment of the placement platform 2.

[0026] During operation, first loosen the rubber head screw 303, rotate the adjusting plate 3, and use the arc groove 301 to drive the connecting rod 204 to slide along the slide groove 201, thereby driving the four sets of clamping blocks 202 to slide along the slide groove 201 in a direction away from the axis of the placement platform 2. Place the antenna under test between the four sets of clamping blocks 202, and rotate the adjusting plate 3 in the opposite direction, driving the four sets of clamping blocks 202 to slide along the slide groove 201 in a direction towards the axis of the placement platform 2, thereby using the four sets of clamping blocks 202 to clamp and fix the antenna under test. The design of the V-shaped groove 203 at one end of the clamping block 202 can make the clamping block 202 fit more closely to the periphery of the antenna under test, which can easily clamp and fix antennas of different specifications. Then, rotate the rubber head screw 303 inside the internal thread bracket 302, so that one end of the rubber head screw 303 presses against the placement platform 2, thereby locking the adjusting plate 3 and ensuring that the antenna under test can be stably clamped. It is convenient and quick, without the need for cumbersome disassembly and assembly of bolts and other fasteners.

[0027] During testing, the telescopic rod 403 drives the sliding sleeve 402 to slide up and down around the support sleeve 401, thereby adjusting the height of the placement platform 2. The first motor 501 drives the support plate 502 to rotate, causing the placement platform 2 to rotate. The cooperation of the annular guide rail 503 and the guide frame 504 guides the rotation of the support plate 502, ensuring stable rotation and thus adjusting the direction of the antenna. The second motor 703 drives a set of transmission wheels 704 to rotate. The transmission belt 705, in conjunction with another set of transmission wheels 704, transmits the rotation to the worm gear 702. The rotation of the worm gear 702 drives the worm wheel 701 to rotate, which in turn drives the mounting shaft 602 to rotate, adjusting the angle of the placement platform 2. The worm wheel 701 and worm gear 702 have self-locking properties, ensuring the stability of the angle adjustment of the placement platform 2. This allows for multi-dimensional adjustment of the antenna under test, facilitating testing.

[0028] Through the above steps, by rotating the adjustment disc 3, the connecting rod 204 slides along the slide groove 201 via the arc groove 301, which in turn drives the four sets of clamping blocks 202 to slide along the slide groove 201, making it convenient to clamp and fix antennas of different specifications. By rotating the rubber head screw 303 inside the internal thread bracket 302, one end of the rubber head screw 303 can press against the placement platform 2, locking the adjustment disc 3, and quickly fixing antennas of different specifications. This effectively improves the efficiency of antenna assembly and disassembly, eliminating the need for cumbersome bolts and other fasteners. This solves the problem that the current method of fixing antennas on the anechoic chamber turntable is cumbersome, cannot quickly fix antennas of different specifications, and has low efficiency.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
