Description

Technical Field

[0001] The present application relates to the field of electromagnetic compatibility testing, and in particular to a door antenna support device. Background Art

[0002] Gate antennas, also known as electric field generators, are essential equipment for electromagnetic compatibility testing. They require two test states: rotational testing and polarization testing. Rotational testing evaluates the gate antenna's electromagnetic radiation and anti-interference performance at different angles, as well as its sensitivity to electromagnetic interference from different directions. Polarization testing determines the gate antenna's reception and transmission performance for electromagnetic waves of different polarization directions, verifying its electromagnetic compatibility in various polarization environments.

[0003] In the prior art, there are devices that perform rotation tests on gate antennas separately, as well as devices that perform polarization tests on gate antennas separately. However, due to the large size and weight of the gate antenna itself, it is extremely inconvenient to disassemble and replace it, which wastes manpower and greatly reduces the testing efficiency of the gate antenna.

[0004] Therefore, it is necessary to provide a new technical solution to improve one or more problems existing in the above solutions. Utility Model Content

[0034] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0035] In addition, the accompanying drawings are merely schematic illustrations of the present application and are not necessarily drawn to scale. Identical reference numerals in the figures denote identical or similar parts, and thus repetitive descriptions thereof will be omitted. Some of the blocks shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0036] In this exemplary embodiment, a door antenna support device is first provided. Figures 1 to 5 As shown in , the door antenna support device for performing electromagnetic compatibility testing on a door antenna includes a support mechanism 100, a rotation mechanism 300, and a clamping mechanism 200. The support mechanism 100 includes a base 110 and a first support rod 120. The first support rod 120 is disposed on the base 110. The base 110 is an I-shaped base, and the first support rod 120 is vertically fixed to the middle rod of the I-shaped base. There are two first support rods 120, thereby improving the stability of the support mechanism 100.

[0037] The rotating mechanism 300 includes a first fixing member 310, a rotating assembly 320, and a second fixing member 330. The first fixing member 310 is mounted on the first support rod 120. The rotating assembly 320 is rotatably mounted on the first fixing member 310, and the output end of the rotating assembly 320 extends through the first fixing member 310. The second fixing member 330 is fixedly connected to the portion extending through the output end of the rotating assembly 320. When the rotating assembly 320 is rotated, the rotation of the output end drives the rotation of the second fixing member 330. Optionally, the input end of the rotating assembly 320 has a handle for easy rotation, facilitating operation.

[0038] It should be noted that the surface of the first fixing member 310 of the rotating mechanism 300 has an arc-shaped groove, and the rear end of the holding portion for easy rotation has a block, which is fixed in the arc-shaped groove, thereby limiting the upper limit of the rotation angle of the rotating assembly 320 to 90°. Figure 5As shown, when rotated to 90°, the gate antenna 400 is in a polarization test state. Optionally, the rotating assembly 320 can be a common rotating structure such as a rotating shaft structure, a worm gear structure, a gear transmission structure, a chain transmission structure, etc.

[0039] The clamping mechanism 200 is used to rotatably clamp the door antenna 400 and is fixedly connected to the rotating assembly 320 via the second fixing member 330 .

[0040] It should be noted that if Figure 2 As shown, both clamping ends of the clamping mechanism 200 have a rotatably connected rotating block 210 , and the door antenna 400 is clamped by the rotating block 210 .

[0041] Further, optionally, the rotating mechanism 300 is slidably disposed on the first support rod 120 , and the position of the door antenna 400 can be adjusted by sliding the rotating mechanism 300 .

[0042] It should be noted that when the rotating mechanism 300 slides to a suitable position, the position can be fixed by means of a clamping block, a bolt, a fastening mechanism, etc.

[0043] Furthermore, the door antenna support device also has an adjustment mechanism 500, which is fixedly connected to the support mechanism 100 at the bottom and to the rotating mechanism 300 at the top, for adjusting the height of the rotating mechanism 300. The adjustment mechanism 500 can be any height-adjustable device such as a threaded adjustment mechanism, a pneumatic adjustment mechanism, a hydraulic adjustment mechanism, or a rack and pinion adjustment mechanism.

[0044] In one embodiment, the adjustment mechanism 500 includes a scissor jack assembly 510 , a third fixing member 520 , and an adjustment rod 530 ;

[0045] The scissor jack assembly 510 is fixedly connected to the support mechanism 100 at the bottom and to the rotating mechanism 300 at the top. Both ends of the scissor jack assembly 510 have third fixing members 520, one of which has an internally threaded through-hole. The first support rod 120 has a through-slot, and the adjustment rod 530 has external threads on one end of the surface adjacent to the third fixing member 520 with the internally threaded through-hole. The adjustment rod 530 is inserted into the through-slot of the first support rod 120 and is threadedly connected to the internally threaded through-hole of the third fixing member 520 with the internally threaded through-hole. The end of the adjustment rod 530 without external threads is rotatably fixedly connected to the third fixing member 520 without the internally threaded through-hole. Optionally, the end of the adjustment rod 530 without external threads has a rotating handle 540.

[0046] It should be noted that Figure 3Taking the case where the middle handle is set on the right side as an example, by rotating the rotating handle 540 clockwise, the third fixing member 520 with an internal threaded through hole on the left side moves to the right through the thread, and the adjusting rod 530 and the third fixing member 530 on the right side move to the left as a whole, thereby driving the scissor jack assembly 510 to perform telescopic movement, thereby adjusting the height of the rotating mechanism 300.

[0047] Furthermore, the first support rod 120 has a first stopper 121 at its lower portion, and the bottom of the scissor jack assembly 510 is fixedly connected to the first stopper 121. The first stopper 121 fixes the bottom of the scissor jack assembly 510 to the first support rod 120, providing support for the scissor jack assembly 510.

[0048] Optionally, the middle portion of the first support rod 120 further includes a second limit block 122 , wherein the second limit block 122 is used to limit the minimum height of the rotating mechanism 300 to prevent the clamping mechanism 200 and the door antenna 400 from falling when the adjustment mechanism 500 fails.

[0049] In one embodiment, the support mechanism 100 further includes a support frame 130, and the top of the first support rod 120 is fixedly connected to the support frame 130, thereby supporting the first support rod 120, thereby preventing the first support rod 120 from bending or shaking due to inconsistent weight on both sides.

[0050] In one embodiment, the support mechanism 100 further includes a first stabilizing member 150 and a second stabilizing member 160. The first stabilizing member 150 is fixedly connected to the support frame 130 and the base 110, and is used to stabilize the connection between the support frame 130 and the base 110. The second stabilizing member 160 is fixedly connected to the first support rod 120 and the base 110, and is used to stabilize the connection point between the first support rod 120 and the base 110.

[0051] It should be noted that the first stabilizing member 150 is a high-strength nylon plate, which enhances the stability of the connection between the base 110 and the support frame 130; the second stabilizing member 160 is a high-strength nylon plate, which enhances the stability of the connection between the base 110 and the first support rod 120.

[0052] In one embodiment, the base 110 has a universal wheel 140 at the bottom, which facilitates the movement of the door antenna support device of the present application through the universal wheel 140 to facilitate electromagnetic compatibility testing. Optionally, the universal wheel 140 also has a locking mechanism to lock when it moves to the target position.

[0053] In one embodiment, the supporting mechanism 100 , the clamping mechanism 200 , the rotating mechanism 300 , and the adjusting mechanism 500 of the present application are all made of fiberglass, so that the entire device has no metal parts.

[0054] When in use, the door antenna support device provided in the embodiment of the present application clamps the door antenna in the clamping mechanism 200, and adjusts the height of the door antenna 400 by the adjustment mechanism 500, thereby performing a rotation test; after the rotation test is completed, the clamping mechanism 200 is rotated 90° by turning the rotating mechanism 300, switching to the polarization test state, and performing a polarization test, thereby realizing the rotation test and polarization test of the door antenna without disassembling and replacing the equipment, thereby improving the electromagnetic compatibility test efficiency of the door antenna, and the height of the door antenna can be adjusted according to actual needs.
