Description

Technical Field

[0001] This utility model mainly relates to the field of reverberation chamber technology, specifically a reverberation chamber stirrer. Background Technology

[0002] An electromagnetic reverberation chamber is a large-scale testing device used for electromagnetic compatibility and radio frequency performance testing of electronic equipment. It is widely used in the fields of automobiles and auto parts, large electronic systems, and especially military electronic products. Its main advantage is that it can achieve high field strength at a relatively low cost and in a limited space.

[0003] After the components of new energy vehicles are successfully manufactured, staff need to conduct magnetic field interference tests on them. In the existing technology, the components are usually placed inside an electromagnetic reverberation chamber for testing. When it is necessary to change the position of the component for multiple tests, the electromagnetic reverberation chamber is usually opened to adjust the position of the component. This not only reduces the testing efficiency, but also requires the magnetic field strength to be adjusted before each test, which is quite cumbersome.

[0004] Therefore, it is necessary to provide a stirrer-free electromagnetic reverberation chamber to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a reverberation chamber stirrer to solve the technical problem mentioned in the background art, where the position of components is usually adjusted by opening the reverberation chamber when multiple experiments are needed to change the position of the components.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A reverberation chamber stirrer includes a reverberation chamber body, a door on the front end of the reverberation chamber body, a mounting frame inside the reverberation chamber body, a lifting plate that can be moved by a first adjustment mechanism on the inner side of the mounting frame, and the top of the lifting plate is connected to a placement frame by two sets of sliding connecting rods. A second adjustment mechanism that drives the placement frame to move is provided above the lifting plate, and the placement frame is located outside the mounting frame.

[0008] Preferably, a tuner is installed at the top interior of the reverberation chamber body.

[0009] Preferably, the first adjustment mechanism includes a stabilizing plate, which is slidably connected to the inner side of the mounting frame. Two sets of rack plates are symmetrically arranged above the stabilizing plate, and the rack plates mesh with gears. The gears are installed on the outer side of the rotating rod, and a first throttle handle for driving the rotating rod to rotate is provided on the outer side of the reverberation chamber body. The ends of the two sets of rack plates are connected to the lifting plate.

[0010] Preferably, the second adjustment mechanism includes an opening slot, which is fixedly installed above the lifting plate. A lead screw mechanism is rotatably arranged inside the opening slot, and the lead screw mechanism can drive a drive block that is slidably arranged inside the opening slot to move. A drive motor that drives the lead screw mechanism to rotate is arranged outside the opening slot, and the end of the drive block is connected to the placement frame.

[0011] Preferably, the first throttle has a limiting hole, and the outside of the reverberation chamber body is provided with a number of limiting slots that cooperate with the limiting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention allows the rotating rod to rotate by operating the first lever in the first adjustment mechanism, which in turn drives the gear and rack plate to mesh and transmit power, thereby realizing the lifting and lowering movement of the lifting plate. At the same time, the drive motor in the second adjustment mechanism drives the lead screw mechanism to rotate, which drives the drive block in the opening slot to move, thereby realizing the forward and backward movement of the placement rack. All of these operations can be performed with the reverberation chamber door closed, eliminating the need to frequently open the door to adjust the position of the component under test, improving the testing efficiency of multiple experiments, and simplifying the experimental process.

[0014] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Please refer to the appendix carefully. Figure 1-3 A reverberation chamber stirrer, wherein a door 2 is provided on the front end face of the reverberation chamber body 1, and an installation frame 3 is provided inside the reverberation chamber body 1. The inner side of the installation frame 3 can drive the lifting plate 5 to move through the first adjustment mechanism 4, and the top of the lifting plate 5 is connected to the placement frame 7 through two sets of sliding connecting rods 6. A second adjustment mechanism 8 is provided above the lifting plate 5 to drive the placement frame 7 to move, and the placement frame 7 is located outside the installation frame 3.

[0024] To further explain, both the mounting bracket 3 and the placement bracket 7 are U-shaped placement brackets, and the mounting bracket 3 can also guide the movement of the placement bracket 7.

[0025] In this embodiment, as Figure 1 As shown, a tuner is installed on the top of the interior of the reverberation chamber body 1. The magnetic field strength is released through the tuner. The tuner is existing technology and will not be described in detail.

[0026] In this embodiment, as Figure 1 and Figure 3As shown, the first adjustment mechanism 4 includes a stabilizing plate 401, which is slidably connected to the inner side of the mounting frame 3. Two sets of rack plates 402 are symmetrically arranged above the stabilizing plate 401, and the rack plates 402 mesh with gears 403. The gears 403 are installed on the outer side of the rotating rod 404. (To reduce the wear of the gears 403, a telescopic rod structure can be set below the lifting plate 5 for auxiliary support. A positioning plate for installing the telescopic rod structure can be fixedly set on the inner side of the mounting frame 3. The positioning plate is located on the upper side of the stabilizing plate 401 and does not affect the later movement of the stabilizing plate 401.) A first handle 405 for driving the rotating rod 404 to rotate is set on the outer side of the reverberation chamber body 1. The placement frame 7 is on the rotating rod 404. The first adjustment mechanism 4 moves up and down. The ends of the two sets of rack plates 402 are connected to the lifting plate 5. By rotating the first throttle 405, the rotation of the rotating rod 404 and the gear 403 can be precisely controlled, thereby driving the rack plates 402 and the lifting plate 5 to move up and down smoothly and precisely. This adjustment method is not only simple to operate, but also can achieve fine adjustment range to meet the height requirements of the placement frame 7 in the experiment. The sliding connection between the stabilizing plate 401 and the inner side of the mounting frame 3 ensures the stability of the structure, so that the lifting plate 5 will not shake or deviate during the movement, ensuring the accuracy and safety of the experiment. The structure of the first adjustment mechanism 4 is relatively simple, and the connection relationship between each component is clear and easy to understand, which facilitates daily maintenance and troubleshooting.

[0027] In this embodiment, as Figure 2 As shown, a limiting hole is provided on the first throttle 405, and several sets of limiting slots that cooperate with the limiting hole are provided on the outside of the reverberation chamber body 1. When the first throttle 405 is rotated to the desired position, the limiting hole can be aligned with the corresponding limiting slot, and the first throttle 405 can be fixed at the desired angle by a pin or other locking mechanism to prevent it from rotating on its own.

[0028] In this embodiment, as Figure 1 and Figure 3 As shown, the second adjustment mechanism 8 includes an opening slot 801, which is fixedly installed above the lifting plate 5. A lead screw mechanism 802 is rotatably installed inside the opening slot 801, and the lead screw mechanism 802 can drive a drive block that is slidably installed inside the opening slot 801 to move. A drive motor that drives the lead screw mechanism 802 to rotate is provided outside the opening slot 801. (The drive motor can be electromagnetically shielded to reduce the interference of the electromagnetic field it generates on the test electromagnetic field.) The end of the drive block is connected to the placement frame 7. By driving the lead screw mechanism 802 to rotate through the drive motor, the moving distance and speed of the drive block inside the opening slot 801 can be controlled, thereby realizing the adjustment of the position of the placement frame 7.

[0029] The specific operating procedure of this utility is as follows: During use, the operator fixes the component to be tested on the top of the placement rack 7, and then releases the magnetic field strength through the tuner to test the component. When it is necessary to adjust the position of the component to be tested, the operator operates the first throttle 405 in the first adjustment mechanism 4, which drives the lifting plate 5 connected to the end of the rack plate 402 to move up and down smoothly and accurately. At the same time, the second adjustment mechanism 8 above the lifting plate 5 drives the lead screw mechanism 802 to rotate through the drive motor. The lead screw mechanism 802 drives the drive block that is slidably set inside the opening slot 801 to move, so the placement rack 7 also moves back and forth. All these operations can be performed with the door 2 closed, without having to frequently open the door 2 to adjust the position of the component to be tested. The height of the placement rack 7 can be adjusted through the first adjustment mechanism 4, and the back and forth position of the placement rack 7 can be adjusted through the second adjustment mechanism 8, thereby realizing the adjustment of the position of the component to be tested placed on the placement rack 7, improving the testing efficiency of multiple experiments and simplifying the experimental procedure.

[0030] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
