At the same time, the shielding plate 40 is spliced between the test bench 32 and the inner wall of the placement cavity 31. By inflating the annular airbag 33, the annular airbag 33 expands and bulges, and then the shielding plate 40 is clamped between the placement cavity 31 and the test bench 32, making the splicing of the shielding plate 40 more firm and stable, and also making the sealing effect good after the shielding plate 40 is spliced. When disassembling, the gas in the annular airbag 33 is released and each shielding plate 40 can be disassembled. At the same time, electromagnetic compatibility detection equipment is also arranged on the test bench 32, so that there is no need to configure test equipment separately after installation.

[0099] Figure 5 and Figure 6 An electromagnetic compatibility outdoor test cabin is implemented. The support member 322 is formed by combining a support bar 3221, a sliding member 3222 and a rotating roller 3223. The support bar 3221 is fixedly arranged on the test bench 32, and two support bars 3221 are symmetrically arranged on the test bench 32 for supporting the front and rear vehicle tires.

The sliding member 3222 is of a trapezoidal structure, and the bottom end is slidably embedded in the sliding groove, and the middle is hollowed out, so that it can slide on the support bar 3221 to adjust the position. Four sliding members 3222 are arranged on each support bar 3221, and every two sliding members 3222 are set as a group, so that two groups of sliding members 3222 are arranged on each support bar 3221, which exactly corresponds to the front and rear two tires of the vehicle. At the same time, the rotating roller 3223 is rotatably connected between the two sliding members 3222, and two rotating rollers 3223 are arranged between each group of sliding members 3222, and the sizes of the two rotating rollers 3223 are different, so that a certain arc is formed after the two rotating rollers 3223 are installed, so as to better abut against the vehicle tires, so that the tires will not shift back and forth when rotating, so that the vehicle runs more stably during detection. Secondly, limiting holes are evenly opened in the sliding grooves of the support bar 3221 to limit the position of the sliding member 3222 after moving and adjusting, so that the sliding member 3222 is more stable.

[0101] Figure 7and Figure 8 An electromagnetic compatibility outdoor test cabin is implemented. At the four corners of the placement cavity 31 of the building platform 30, multiple telescopic rods 34 are fixedly connected. At the bottom of the multiple telescopic rods 34, an arc-shaped base 35 is integrally formed. The multiple telescopic rods 34 are fixed in the placement cavity 31 of the building platform 30 through the arc-shaped base 35. Moreover, the multiple telescopic rods 34 are also of an arc-shaped structure. At the same time, the multiple telescopic rods 34 are provided with inlay grooves along the two ends of the arc. Due to the structural limitation of the multiple telescopic rods 34 themselves, the inlay grooves are distributed in a stepped manner, so that the inlay grooves on each section upward along the height of the multiple telescopic rods 34 are distributed inward. Thus, when the multiple telescopic rods 34 are retracted, they will not be interfered, and thus the multiple telescopic rods 34 can be well retracted. At the same time, when telescoping and extending, the shielding plate 40 can be better inlaid and clamped, making the two ends of the shielding plate 40 contact the multiple telescopic rods 34 more closely and improving the sealing effect.

Setting both ends of the inlay plate 41 in the length direction as a stepped shape enables the inlay plate 41 to better adapt when contacting the inlay grooves on the multiple telescopic rods 34. Thus, when the inlay plate 41 is connected to the multiple telescopic rods 34, the connection is closer, and there will be no protrusion or inability to inlay at the edge. The shielding members 42 are detachably arranged on the inlay plate 41, and when the shielding members 42 are arranged, they cover the entire end face of the inlay plate 41, so as to better prevent the entry of external electromagnetic signals and reduce electromagnetic interference during the test.

The spherical hinge joint 422 is formed by combining a spherical outer shell and a metal ball. The spherical outer shell is fixedly arranged on the connecting block 421, and the metal ball is embedded in the spherical outer shell. The metal ball is wrapped by the spherical outer shell, and the shielding block 423 is fixedly connected to the metal ball, so as to connect the shielding block 423 to the connecting block 421 and then lay it on the inlay panel 41. The shielding block 423 is selected from steel plates, copper plates, aluminum plates or stainless steel plates, and an absorbing sponge 4231 is pasted on the surface, so as to better shield the internal electromagnetic waves from diffusing outwards and also shield the external electromagnetic waves from entering the test cabin, thereby reducing the interference during the electromagnetic compatibility test and making the detection data more real.

[0106] According to the electromagnetic compatibility outdoor test cabin provided by an embodiment of the present invention, the shielding plate 40 further includes a top sealing plate 43, the top sealing plate 43 is hermetically inlaid on the top of the test cabin formed by splicing the inlay panels 41 to seal the test cabin formed by splicing the inlay panels 41; wherein, the top sealing plate 43 is a rectangular plate structure, and a flexible rubber layer is arranged on the inlay surface of the top sealing plate 43, and the flexible rubber layer contacts the inlay panel 41 to achieve sealing.

[0107] Figure 1An electromagnetic compatibility outdoor test cabin is implemented. The shielding plate 40 also includes a top sealing plate 43. The structure of the top sealing plate 43 is different from that of other shielding plates 40. Flexible rubber is provided at the bottom. At the same time, wave-absorbing sponges 4231 are arranged around the edge of the flexible rubber. When installing, the flexible rubber is clamped at the top of the cavity formed by the other four shielding plates 40. The elastic force of the flexible rubber makes the top sealing plate 43 contact more closely with the top of the cavity formed by the shielding plates 40. At the same time, the generated divergent electromagnetic waves are absorbed by the arranged wave-absorbing sponges 4231 and do not spread to the outside. At the same time, external electromagnetic waves are also prevented from entering the cavity interior, thereby achieving a sealing effect and making the detection more accurate.

[0108] According to the electromagnetic compatibility outdoor test cabin provided by the embodiment of the present invention, the shielding block 423 includes a wave-absorbing sponge 4231, and the wave-absorbing sponge 4231 is arranged at one end of the shielding block 423 away from the ball hinge joint 422; a reflection strip 4232, and the reflection strip 4232 is arranged inside the shielding block 423; wherein, the reflection strip 4232 is arranged in a wavy structure for reflecting electromagnetic waves.

[0109] Figure 12 An electromagnetic compatibility outdoor test cabin is implemented. The inside of the shielding block 423 is set as a hollow structure, and a reflection strip 4232 is arranged inside the shielding block 423. The width of the reflection strip 4232 is the same as the length of the cavity of the shielding block 423 and is laid in the cavity of the shielding block 423. At the same time, the reflection strip 4232 is in a wavy structure. When internal electromagnetic waves or external electromagnetic waves enter the inside of the shielding block 423, the electromagnetic waves can be retained or reflected by the wavy reflection strip 4232. Thereby, the internal electromagnetic waves are prevented from being reflected out of the test cabin, and at the same time, external electromagnetic waves are also blocked from entering the test cabin to interfere with the electromagnetic test, thereby making the detection data of the electromagnetic compatibility test more accurate.

[0110] According to the electromagnetic compatibility outdoor test cabin provided by the embodiment of the present invention, the building platform 30 further includes a plurality of electric telescopic rods 36. The plurality of electric telescopic rods 36 are fixedly arranged at one end of the building platform 30 close to the bearing platform 21. The plurality of electric telescopic rods 36 are used to support the building platform 30; wherein, the electric telescopic rods 36 are distributed at the four corners of the building platform 30. At the same time, storage grooves are opened on the bearing platform 21 corresponding to the electric telescopic rods 36, and the electric telescopic rods 36 are placed in the storage grooves. At the same time, a plurality of embedding columns 37 are arranged beside the electric telescopic rods 36, and buffer grooves are opened on the plurality of embedding columns 37 and elastic plates are inclined in the buffer grooves.

[0111] Figure 3An electromagnetic compatibility outdoor test cabin is implemented. Electric telescopic rods 36 are fixedly arranged at the four corners of the bottom of the building platform 30. The electric telescopic rods 36 are used to level the balance of the building platform 30 when it is built on the ground, so that the building platform 30 is better suitable for different terrains, thereby improving the use efficiency of the electromagnetic compatibility test cabin. At the same time, a storage groove is provided on the bearing platform 21 corresponding to the electric telescopic rod 36. When the building platform 30 is installed on the transport vehicle 10, the electric telescopic rod 36 can be better received in the storage groove, so that when the building platform 30 is installed on the transport vehicle 10, it contacts the bearing platform 21, making the building platform 30 more flat. Secondly, the inserted column 37 is inserted into the bearing platform 21 during installation, and an insertion hole is provided on the bearing platform 21, so that the surfaces of the insertion hole and the inserted column 37 are in contact during insertion. At the same time, since a buffer groove is provided on the inserted column 37 and an elastic plate is inclined in the buffer groove, when the inserted column 37 is placed in the insertion hole, the elastic plate on the inserted column 37 is squeezed by the inner wall of the insertion hole and then contracted into the buffer groove. When the inserted column 37 completely enters the insertion hole, the elastic plate has a force to expand outward due to the reaction force of the elastic plate, so that the elastic plate abuts against the inner wall of the insertion hole, thereby inserting the inserted column 37 into the insertion hole, making the connection between the inserted column 37 inserted into the insertion hole and the bearing platform 21 more firm, and further making the connection between the bearing platform 21 and the building platform 30 more firm. Secondly, it also makes it more convenient to remove the building platform 30 from the bearing platform 21 during disassembly.

[0112] According to the electromagnetic compatibility outdoor test cabin provided by the embodiment of the present invention, the disassembly device 50 includes a mounting plate 51. The mounting plate 51 is arranged on the transport base 20, and a connection groove is provided on the side of the mounting plate 51 close to the transport base 20; a hydraulic lifting rod 52, the hydraulic lifting rod 52 is arranged in the connection groove, and the hydraulic lifting rod 52 performs telescopic movement in the vertical direction; a hydraulic extension rod 53, the hydraulic extension rod 53 is arranged at the telescopic end of the hydraulic lifting rod 52, and the hydraulic extension rod 53 performs telescopic movement in the horizontal direction; wherein, the overall test cabin is lifted and disassembled by the hydraulic lifting rod 52 and the hydraulic extension rod 53.

[0113] Figure 3 and Figure 13An electromagnetic compatibility outdoor test cabin is implemented. The disassembly device 50 is formed by combining a mounting plate 51, a hydraulic lifting rod 52, and a hydraulic extension rod 53. The construction platform 30 is lifted by the hydraulic lifting rod 52 to separate the construction platform 30 from the transportation base 20. After being lifted, the construction platform 30 is extended towards the side wall of the transport vehicle 10 by the hydraulic extension rod 53. When the construction platform 30 is extended outward by the hydraulic extension rod 53, a placement groove is opened at the bottom of the construction platform 30 corresponding to the hydraulic extension rod 53. One end of the placement groove penetrates the edge of the construction platform 30, and the other end is 30 cm away from the edge. When the hydraulic extension rod 53 is extended, the extended end abuts against the closed end of the placement groove, pushing the construction platform 30 to move towards the vehicle side, and then moving the construction platform 30 out of the vehicle, so that the bottom of the construction platform 30 faces the ground. Slowly retract the hydraulic lifting rod 52 to lower the construction platform 30. When the retraction reaches the limit, start the electric telescopic rod 36 below the construction platform 30 to extend the electric telescopic rod 36 downward until it touches the ground to support the construction platform 30. Subsequently, remove the hydraulic lifting rod 52 and the hydraulic extension rod 53 and place the construction platform 30 on the ground, which facilitates the vehicle to be tested to enter the test cabin and facilitates on-site vehicle testing. Both the hydraulic lifting rod 52 and the hydraulic extension rod 53 are connected to the vehicle's electrical system, and the hydraulic lifting rod 52 and the hydraulic extension rod 53 are controlled through the vehicle's control screen.

[0114] Usage process:

[0115] During use, install the building platform 30 on the transport base 20 of the transport vehicle 10. Next, place multiple telescopic rods 34 on the building platform 30, and assemble and splice the shielding plates 40 through the multiple telescopic rods 34, so that the shielding plates 40 form a test cabin on the building platform 30. When assembling the shielding plates 40, first lay shielding blocks 423 on one side of the shielding plate 40. By using the shielding blocks 423 to block the shielding plate 40, it is possible to better separate and block the electromagnetic waves inside and outside the cabin, thereby making the detected data more accurate. Secondly, during assembly, through the interaction of the annular airbag 33 and the abutting strip 321 provided on the building platform 30, when the annular airbag 33 is inflated, the annular airbag 33 abuts and fixes the shielding plate 40, so that the bottom connection of the shielding plate 40 is tighter. After assembling the shielding plates 40, inlay and install the top sealing plate 43 at the top, thus forming an electromagnetic test cabin with good sealing and shielding performance. Then, transport it to various areas for on-site detection by the transport vehicle 10. At the same time, during detection, it can be detected on the vehicle or on the ground. When detecting on the vehicle, the electromagnetic compatibility of the accessories of new energy vehicles is detected. When detecting on the ground, the electromagnetic compatibility performance of the whole vehicle is detected. It is necessary to remove the detection cabin from the vehicle. During disassembly, use the disassembly device 50 to remove the building platform 30 from the transport vehicle 10, making the disassembly more convenient. Then, conduct detection through assembly. The assembly is the same as the assembly on the vehicle, except that on the ground, an electric telescopic rod 36 is required to level the ground so that it can adapt to different terrains. After leveling, conduct electromagnetic compatibility detection. At the same time, through the provided support member 322, the wheels of the vehicle can be lifted when detecting the vehicle, so that the vehicle is in a running state during the detection process, and thus electromagnetic anti-interference data during vehicle operation can be obtained. This solves the problems that existing new energy vehicles cannot be detected on site, the test cabin cannot be moved, cannot be built and disassembled outdoors, and can only be used at a fixed position.
