Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to an antenna OTA performance testing device. Background Technology

[0002] An over-the-air (OTA) performance testing device is used to evaluate the performance of wireless communication antennas. OTA refers to a testing method that transmits signals directly through the air without the need for a cable connection. This device can simulate signal transmission conditions in a real-world environment, testing parameters such as the antenna's radiation performance, reception performance, and coverage range to ensure that the antenna's performance meets requirements in actual use.

[0003] Chinese patent CN222852285U discloses an antenna OTA performance testing device, including a testing chamber, a testing device body, an arc rod, a testing head, and a testing plate. A bottom groove is formed in the middle of the bottom surface of the testing chamber. A lower plate is slidably mounted on the inner wall of the bottom groove, and an upper plate is rotatably mounted on the upper surface of the lower plate. Two electric telescopic rods are fixedly mounted on the bottom surface of the bottom groove. A first motor is fixedly mounted inside the lower plate. A bottom block is fixedly mounted in the middle of the lower surface of the testing device body, and rollers are rotatably mounted on the lower side of the inner wall of the bottom block. In this invention, inserting the mounting block into the arc rod and releasing the locking rod makes it easier to install the testing head. When installing the testing plate, pulling the middle rod inserts the embedding plate into the arc rod, and pushing the middle rod causes the embedding block on the slider to engage in the embedding groove, facilitating the installation of the testing parts.

[0004] The existing antenna OTA performance testing device uses a clamp and a push spring to fix the test head. However, the spring force may decrease after long-term use, causing the clamp to loosen and affecting the stability of the test head. The test plate is mechanically engaged with the insert block and the insert plate. If the slider or groove wears, it may cause unstable fixing. In addition, under high-frequency assembly and disassembly or vibration environment, the test head and the test plate will shake, affecting the test accuracy and reducing the practicality of the antenna OTA performance testing device.

[0032] Example 1

Furthermore, a connecting arc rod 407 is connected, and connecting blocks 408 are connected to both sides of the arc rod 407. The connecting blocks 408 are provided with embedding grooves. A connecting rod 409 is connected to one end of the arc rod 407. Slots 410 are provided on both sides of the connecting rod 409. An embedded magnet is provided at one end of the connecting rod 409. A detection plate 5 is connected to the arc rod 407. Embedding blocks 501 are connected to both sides of the detection plate 5. A detection head 6 is connected below the connecting rod 409. A U-shaped plate 601 is connected above the detection head 6. Insert blocks 602 are connected to both sides of the U-shaped plate 601, and a ferromagnetic block 603 is connected to one side.

[0034] To further explain, the embedding block 501 is connected within the embedding groove, and a limiting component is connected below the detection plate 5; the U-shaped plate 601 is connected to both sides of the connecting rod 409, and the insert block 602 is connected within the slot 410. Both the insert block 602 and the slot 410 have anti-slip textures on their connecting surfaces, and the ferromagnetic block 603 is connected to the magnet. This dual-method fixation of the U-shaped block and the connecting rod 409 helps prevent the detection head 6 from loosening, improving the accuracy of OTA performance testing for automotive antennas.

[0035] Further explanation: The limiting components include an electric telescopic rod b403, an adjusting plate 404, a limiting plate 405, and a clamping plate 406. The electric telescopic rod b403 is connected to the support plate 402. The drive end of the electric telescopic rod b403 is connected to the adjusting plate 404. The limiting plate 405 is connected above the adjusting plate 404, and the clamping plate 406 is connected to one side. The limiting plate 405 is connected below the detection plate 5, and the clamping plate 406 is connected to the periphery of the arc rod 407. The electric telescopic rod b403 is connected to the control system and power supply via wires. The electric telescopic rod b403 facilitates the adjustment of the position of the limiting plate 405. After the detection plate 5 is installed, adjusting the movement of the limiting plate 405 allows for limiting the movement of the area below the detection plate 5, improving the accuracy of OTA performance testing of the automotive antenna.

[0036] Example 2

[0037] like Figure 1 and Figure 2 As shown, the antenna OTA performance testing device proposed in this utility model, based on the above embodiment, further details the specific components of the chassis 2 and the placement assembly, as well as their cooperation method.

[0038] To further explain, chassis 2 is provided with a circumferential groove. A bottom block is slidably mounted on the inner wall of the circumferential groove. A servo motor is mounted on the upper side of the inner wall of the bottom block, and a roller is rotatably mounted on the lower side of the inner wall of the bottom block. The output end of the servo motor is connected to the roller via a belt. The bottom block is connected to the lower part of the moving plate 401. The servo motor is connected to the control system and power supply via wires. When the servo motor is started, it drives the roller to rotate. The rotating roller drives the bottom block to slide inside the circumferential groove. The bottom block drives the moving plate 401, thereby enabling the device to perform OTA performance testing on the antenna of the vehicle.

[0039] Further explanation: The placement assembly includes a turntable 3, a drive motor 301, an annular sleeve 302, and an electric telescopic rod a303. The turntable 3 is connected to the output end of the drive motor 301 at its bottom. The annular sleeve 302 is connected to the periphery of the drive motor 301.

The lower end of the electric telescopic rod a303 is set at the bottom of a groove, which is set on the testing chamber 1. The drive motor 301 and the electric telescopic rod a303 are connected to the control system and power supply via wires. When a car is placed on the turntable 3, starting the drive motor 301 causes the turntable 3 to rotate, which in turn rotates the car. By activating the electric telescopic rod a303, the height of the turntable 3 can be easily adjusted, thereby adjusting the height of the car, facilitating the use of the antenna OTA performance testing device.

[0040] The working principle of this utility model is as follows: In use, the operator connects the detection plate 5 and the arc rod 407. The embedding blocks 501 on both sides of the detection plate 5 move and embed into the embedding grooves. The embedding grooves are embedded below the connecting block 408, which is connected to both sides of the arc rod 407, thereby connecting the detection plate 5 and the arc rod 407. After the detection plate 5 is installed, the electric telescopic rod b403 is activated. The driving end of the electric telescopic rod b403 causes the adjusting plate 404 to move upward. The adjusting plate 404 drives the limiting plate 405 and the clamping plate 406. The limiting plate 405 and the clamping plate 406 move below the detection plate 5, achieving... The detection plate 5 is limited at the bottom to increase the stability of the connection. Then, the detection head 6 slides in the slot 410 through the inserts 602 on both sides of the U-shaped plate 601, so that the U-shaped plate 601 and the connecting rod 409 are connected. The U-shaped plate 601 drives the ferromagnetic block 603. The ferromagnetic block 603 moves and connects with the magnet embedded in the connecting rod 409. At the same time, anti-slip texture is set on the connection end face of the inserts 602 and the slot 410. The dual operation of the U-shaped plate 601 and the connecting rod 409 increases the stability of the connection of the detection head 6. The connection stability of the components of the detection device is improved, which facilitates the improvement of the accuracy of OTA performance testing of automobile antennas.

[0041] 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 thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
