Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic compatibility shielding chamber technology, and particularly relates to an electromagnetic compatibility shielding chamber. Background Technology

[0002] An electromagnetic compatibility (EMC) shielding chamber is a device used to prevent electromagnetic interference. It is an enclosed space made of conductive materials. Its main function is to provide a low-electromagnetic-interference environment for internal electronic equipment or test objects by shielding them from external electromagnetic field interference. At the same time, it can also prevent internal electromagnetic radiation from leaking into the external environment, ensuring the normal operation of the equipment and the accuracy of test results.

[0003] For example, Chinese patent CN219042415U discloses an electromagnetic compatibility (EMC) shielding cabin. The EMC shielding cabin has a movable component at its bottom, which includes a housing, a bidirectional lead screw, a moving block, a movable rod, a lifting plate, a sliding rod, and a spring. The EMC shielding cabin is located on top of the housing. This EMC shielding cabin achieves a double shielding effect through shielding layers on both the outer and inner shells. The conductive foam can also absorb electromagnetic waves, enabling the EMC shielding cabin to possess excellent EMC shielding functionality. The movable component facilitates the movement of the EMC shielding cabin. This utility model relates to the field of EMC shielding technology, specifically providing an EMC shielding cabin.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, when personnel need to move the device, they need to manually turn the handle to extend the wheels. However, common electromagnetic compatibility shielding cabins are large and heavy, requiring significant force to turn the handle and extend the wheels. This process is labor-intensive and poses certain safety hazards. Therefore, we propose an electromagnetic compatibility shielding cabin. Utility Model Content

[0006] The purpose of this invention is to provide an electromagnetic compatibility shielding chamber to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides an electromagnetic compatibility shielding chamber, comprising:

[0008] A movable seat, on the top of which a shielding chamber body is fixedly installed, a groove is provided in the body of the shielding chamber body, a first shielding layer is fixedly installed in the groove, a rotating door is rotatably installed on one side of the shielding chamber body, a rectangular groove is provided in the rotating door, a second shielding layer is fixedly installed in the rectangular groove, and a sealing gasket that contacts the shielding chamber body is fixedly installed on the rotating door.

[0009] A limiting component, located on the shielded cabin body, is used to limit the movement of the revolving door;

[0010] Two movable slots are provided, both of which are located at the bottom of the movable seat. Rotating rods are symmetrically and rotatably installed in the movable slots. Rollers are rotatably installed at the bottom of the rotating rods. Sliding blocks are symmetrically and slidably installed in the movable slots. Connecting rods that rotate with the corresponding rotating rods are rotatably installed at the bottom of the sliding blocks. A bidirectional threaded rod is rotatably installed in the movable slots. One end of the bidirectional threaded rod passes through the two sliding blocks.

[0011] A drive assembly, located within a movable base, is used to drive two bidirectional threaded rods to rotate.

[0012] In this technical solution, when personnel need to move the shielded cabin body, the two bidirectional threaded rods can be rotated by the set drive component. Under the action of the threads, the rotation of the bidirectional threaded rods will drive the two sliding blocks to move, so that the two sliding blocks move away from each other. At the same time, the movement of the sliding blocks will squeeze the rotating rod through the connecting rod, causing the rotating rod to rotate. Meanwhile, the connecting rod will rotate in the movable groove. The rotation of the rotating rod will drive the rollers to rotate downward. The downward rotation of the four rollers will squeeze the ground and support the moving seat. The moving seat can lift the shielded cabin body. Then, personnel can push the shielded cabin body to move. With the rolling action of the four rollers, it is ensured that personnel can easily move the shielded cabin body. At the same time, it can also ensure that the four rollers can automatically extend and retract automatically without the need for manual labor, thus saving manpower.

[0013] When personnel need to open the shielded cabin body, they can first release the limit on the rotating door through the set limit components. Then, personnel can rotate the rotating door to open the shielded cabin body. Shielding layer one can completely enclose the inner cavity of the moving seat, while shielding layer two enables the rotating door to also have a shielding function. When the rotating door is closed, the inner cavity of the moving seat can be completely enclosed by shielding layer two and shielding layer one, thereby strengthening the shielding function of the shielded cabin body and making the shielding effect of the shielded cabin body better.

[0014] In the above technical solution, the limiting component further includes:

[0015] Connector block two is fixedly installed on one side of the revolving door. Connector block one is fixedly installed on the shielding cabin body and on one side of connector block two. Connector block one and connector block two are connected to the same connector rod.

[0016] In this technical solution, when personnel need to open the shielded cabin body, they can first move the plug rod upwards to pull it out from plug block one and plug block two. At this time, the plug rod can release the limit on plug block one and plug block two, thereby releasing the limit on the rotating door. Then, personnel can rotate the rotating door to open the shielded cabin body. Shielding layer one can completely enclose the inner cavity of the moving seat, while shielding layer two enables the rotating door to also have a shielding function. When the rotating door is closed, the inner cavity of the moving seat can be completely enclosed by shielding layer two and shielding layer one, thereby strengthening the shielding function of the shielded cabin body and making the shielding effect of the shielded cabin body better.

[0017] In the above technical solution, the plug rod has a U-shaped structure, and the second plug block is integrally formed with the revolving door.

[0018] In this technical solution, the structural stability of the plug-in rod is ensured, and the structural stability of the plug-in block two and the revolving door is guaranteed.

[0019] In the above technical solution, the driving component further includes:

[0020] Two rotating slots are provided, each located within a movable base and on the periphery of two bidirectional threaded rods. Worm gears are fixedly installed on each of the two bidirectional threaded rods within the two rotating slots. Worms are meshed with the bottom of each worm gear within the rotating slot. A mounting slot is provided within the movable base between the two rotating slots. A dual-axis motor is fixedly installed within the mounting slot. The two output shafts of the dual-axis motor extend through both sides of the mounting slot to the corresponding rotating slots and are coaxially connected to the worms.

[0021] In this technical solution, starting the dual-axis motor causes its two output shafts to drive two worm gears to rotate. Under meshing action, the worm gears rotate, causing the worm wheel to rotate, which in turn drives the bidirectional threaded rod to rotate. The threaded rod's rotation causes two sliding blocks to move away from each other. Simultaneously, the sliding blocks' movement presses against the rotating rod via a connecting rod, causing the rotating rod to rotate. The connecting rod rotates within the movable groove, and the rotating rod's rotation causes the rollers to rotate downwards. The four rollers rotating downwards press against the ground, supporting the movable seat. The movable seat then lifts the shielded cabin body, allowing personnel to easily move it. The rolling action of the four rollers ensures that personnel can easily move the shielded cabin body, while also guaranteeing that the four rollers can automatically extend and retract without manual intervention, thus saving manpower.

[0022] In the above technical solution, the worm gear is rotatably connected to the rotating groove, the worm is rotatably connected to the rotating groove, and both output shafts of the dual-axis motor are rotatably connected to the moving base.

[0023] In this technical solution, it is ensured that the worm gear can rotate normally in the rotating groove, the worm can rotate normally in the rotating groove, and the two output shafts of the dual-axis motor can rotate normally in the moving seat.

[0024] In the above technical solution, the connecting rod is further movably connected to the movable groove.

[0025] In this technical solution, it is ensured that the connecting rod can rotate and move within the movable groove.

[0026] In the above technical solution, the rotating rod is inclined and the connecting rod is inclined.

[0027] In this technical solution, the structural stability of the rotating rod and the connecting rod is ensured.

[0028] The beneficial effects of this utility model are:

[0029] This electromagnetic compatibility shielding chamber, through the coordinated operation of the drive assembly, bidirectional threaded rod, sliding block, connecting rod, rotating rod, movable groove, and rollers, ensures that personnel can easily move the main body of the shielding chamber. At the same time, it can also ensure that the four rollers can automatically extend and retract without the need for manual labor, thus saving manpower. Attached Figure Description

[0046] Example 1:

[0047] Please see Figure 1 - Figure 9 As shown, this embodiment provides an electromagnetic compatibility shielding chamber, including:

[0048] The mobile base 1 has a shielding chamber body 2 fixedly installed on its top. The shielding chamber body 2 has a groove 3 inside. A shielding layer 4 is fixedly installed inside the groove 3. A rotating door 5 is rotatably installed on one side of the shielding chamber body 2. A rectangular groove 6 is opened inside the rotating door 5. A shielding layer 7 is fixedly installed inside the rectangular groove 6. A sealing gasket 8 that contacts the shielding chamber body 2 is fixedly installed on the rotating door 5.

[0049] A limiting component is located on the shielded cabin body 2 and is used to limit the revolving door 5.

[0050] Two movable slots 12 are provided at the bottom of the movable seat 1. Rotating rods 13 are symmetrically rotatably installed in the movable slots 12. Rollers 14 are rotatably installed at the bottom of the rotating rods 13. Sliding blocks 16 are symmetrically slidably installed in the movable slots 12. Connecting rods 15 that rotate with the corresponding rotating rods 13 are rotatably installed at the bottom of the sliding blocks 16. A bidirectional threaded rod 22 is rotatably installed in the movable slots 12. One end of the bidirectional threaded rod 22 passes through the two sliding blocks 16.

[0051] The drive assembly is located inside the movable base 1 and is used to drive the two bidirectional threaded rods 22 to rotate.

[0052] When personnel need to move the shielded cabin body 2, the two bidirectional threaded rods 22 can be rotated by the drive assembly. Under the action of the threads, the rotation of the bidirectional threaded rods 22 will drive the two sliding blocks 16 to move, so that the two sliding blocks 16 move away from each other. At the same time, the movement of the sliding blocks 16 will squeeze the rotating rod 13 through the connecting rod 15, causing the rotating rod 13 to rotate. Meanwhile, the connecting rod 15 will rotate in the movable groove 12. The rotation of the rotating rod 13 will drive the rollers 14 to rotate downward. The downward rotation of the four rollers 14 will squeeze the ground and support the moving seat 1. The moving seat 1 can lift the shielded cabin body 2. Then, personnel can push the shielded cabin body 2 to move. Under the action of the four rollers 14, it is ensured that personnel can easily move the shielded cabin body 2. At the same time, it can also ensure that the four rollers 14 can automatically extend and retract automatically without the need for manpower, thus saving manpower.

[0053] When personnel need to open the shielded cabin body 2, they can first release the limit on the rotating door 5 through the set limit components. Then, personnel can rotate the rotating door 5 to open the shielded cabin body 2. The first shielding layer 4 can completely wrap the inner cavity of the moving seat 1. At the same time, the second shielding layer 7 can also make the rotating door 5 have a shielding function. When the rotating door 5 is closed, the inner cavity of the moving seat 1 can be completely wrapped by the second shielding layer 7 and the first shielding layer 4, thereby strengthening the shielding function of the shielded cabin body 2 and making the shielding effect of the shielded cabin body 2 better.

[0054] Example 2:

[0055] This embodiment provides an electromagnetic compatibility shielding chamber, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component:

[0056] Plug-in block 2 10 is fixedly installed on one side of the rotating door 5. Plug-in block 1 9 is fixedly installed on the shielded cabin body 2 and on one side of plug-in block 2 10. The same plug-in rod 11 is plugged into plug-in block 1 9 and plug-in block 2 10.

[0057] When personnel need to open the shielded cabin body 2, they can first move the plug rod 11 upwards to pull it out from the plug block 9 and plug block 10. At this time, the plug rod 11 can release the limit on the plug block 9 and plug block 10, thereby releasing the limit on the rotating door 5. Then, personnel can rotate the rotating door 5 to open the shielded cabin body 2. The shielding layer 1 4 can completely wrap the inner cavity of the moving seat 1. At the same time, the shielding layer 2 7 can also make the rotating door 5 have a shielding function. When the rotating door 5 is closed, the inner cavity of the moving seat 1 can be completely wrapped by the shielding layer 2 7 and the shielding layer 1 4, thereby strengthening the shielding function of the shielded cabin body 2 and making the shielding effect of the shielded cabin body 2 better.

[0058] Example 3:

[0059] This embodiment provides an electromagnetic compatibility shielding cabin, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the plug rod 11 has a U-shaped structure, and the plug block 10 and the rotating door 5 are integrally formed.

[0060] This ensures the structural stability of the plug-in rod 11 and guarantees the structural stability of the plug-in block 10 and the revolving door 5.

[0061] Example 4:

[0062] This embodiment provides an electromagnetic compatibility shielding chamber, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the driving component includes:

[0063] Two rotating slots 17 are formed within the movable seat 1 and located on the periphery of two bidirectional threaded rods 22. Worm gears 18 are fixedly installed on the two bidirectional threaded rods 22 and within the two rotating slots 17. Worm gears 19 are meshed with the bottom of the worm gears 18 and within the rotating slots 17. A mounting slot 20 is formed within the movable seat 1 and between the two rotating slots 17. A dual-axis motor 21 is fixedly installed within the mounting slot 20. The two output shafts of the dual-axis motor 21 extend through both sides of the mounting slot 20 to the corresponding rotating slots 17 and are coaxially connected to the worm gears 19.

[0064] When the dual-axis motor 21 is started, its two output shafts drive two worm gears 19 to rotate. Under the action of meshing, the rotation of the worm gears 19 drives the worm wheel 18 to rotate, which in turn drives the bidirectional threaded rod 22 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 22 drives two sliding blocks 16 to move, causing the two sliding blocks 16 to move away from each other. At the same time, the movement of the sliding blocks 16 will press the rotating rod 13 through the connecting rod 15, causing the rotating rod 13 to rotate. Meanwhile, the connecting rod 15 will rotate within the movable groove 12. The rotation of the rotating rod 13 will drive the rollers 14 to rotate downward. The downward rotation of the four rollers 14 will press against the ground and support the movable seat 1. The movable seat 1 can lift the shielded cabin body 2. Subsequently, personnel can push the shielded cabin body 2 to move. With the rolling action of the four rollers 14, personnel can easily move the shielded cabin body 2. At the same time, the four rollers 14 can automatically extend and retract without the need for manual labor, thus saving manpower.

[0065] Example 5:

[0066] This embodiment provides an electromagnetic compatibility shielding cabin, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the worm gear 18 is rotatably connected to the rotating groove 17, the worm 19 is rotatably connected to the rotating groove 17, and both output shafts of the dual-axis motor 21 are rotatably connected to the moving seat 1.

[0067] Specifically, it ensures that the worm gear 18 can rotate normally in the rotating groove 17, that the worm 19 can rotate normally in the rotating groove 17, and that the two output shafts of the dual-axis motor 21 can rotate normally in the moving seat 1.

[0068] Example 6:

[0069] This embodiment provides an electromagnetic compatibility shielding cabin, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the connecting rod 15 is movably connected to the movable slot 12.

[0070] This ensures that the connecting rod 15 can rotate and move within the movable groove 12.

[0071] Example 7:

[0072] This embodiment provides an electromagnetic compatibility shielding cabin, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the rotating rod 13 has an inclined structure, and the connecting rod 15 has an inclined structure.

[0073] This ensures the structural stability of the rotating rod 13 and the connecting rod 15.

[0074] Working principle: When personnel need to move the shielded cabin body 2, the dual-axis motor 21 can be started first. The two output shafts of the dual-axis motor 21 will drive the two worm gears 19 to rotate respectively. Under the action of meshing, the rotation of the worm gear 19 will drive the worm wheel 18 to rotate. The rotation of the worm wheel 18 will drive the bidirectional threaded rod 22 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 22 will drive the two sliding blocks 16 to move, so that the two sliding blocks 16 move away from each other. At the same time, the movement of the sliding blocks 16 will squeeze the rotating rod 13 through the connecting rod 15, so that... When the rotating rod 13 rotates, the connecting rod 15 will rotate within the movable slot 12. The rotation of the rotating rod 13 will drive the rollers 14 to rotate downwards. The downward rotation of the four rollers 14 will press against the ground and support the movable seat 1. The movable seat 1 can lift the shielded cabin body 2. Subsequently, personnel can push the shielded cabin body 2 to move. With the rolling action of the four rollers 14, it is ensured that personnel can easily move the shielded cabin body 2. At the same time, it can also ensure that the four rollers 14 can automatically extend and retract without the need for manual labor, thus saving manpower.

[0075] When personnel need to open the shielded cabin body 2, they can first move the plug rod 11 upwards to pull it out from the plug block 9 and the plug block 10. At this time, the plug rod 11 can release the limit on the plug block 9 and the plug block 10, thereby releasing the limit on the rotating door 5. Then, personnel can rotate the rotating door 5 to open the shielded cabin body 2. The shielding layer 1 4 can completely cover the inner cavity of the moving seat 1. At the same time, the shielding layer 2 7 can also make the rotating door 5 have a shielding function. When the rotating door 5 is closed, the inner cavity of the moving seat 1 can be completely covered by the shielding layer 2 7 and the shielding layer 1 4, thereby strengthening the shielding function of the shielded cabin body 2 and making the shielding effect of the shielded cabin body 2 better.

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
