At the same time, the reflection strip 4232 is a wavy structure, so that when internal electromagnetic waves or external electromagnetic waves enter the interior of the shielding block 423, the electromagnetic waves can be retained or reflected by the wavy reflection strip 4232, thereby avoiding the internal electromagnetic waves from being reflected out of the cabin, and also preventing the external electromagnetic waves from entering the cabin to interfere with the electromagnetic test, thereby making the detection data of the electromagnetic compatibility test more accurate.

[0047] According to the electromagnetic compatibility outdoor test cabin provided by the embodiment of the present invention, the building platform 30 also includes a plurality of electric telescopic rods 36, which are fixedly arranged at one end of the building platform 30 close to the supporting platform 21, and 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, and at the same time, storage grooves are opened on the supporting platform 21 corresponding to the electric telescopic rods 36, and the electric telescopic rods 36 are placed in the storage grooves, and at the same time, a plurality of inlay columns 37 are arranged next to the electric telescopic rods 36, and a buffer groove is opened on the plurality of inlay columns 37, and an elastic plate is obliquely arranged in the buffer groove.

[0048] Figure 3An electromagnetic compatibility outdoor test cabin is implemented in the present invention. 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 adjust 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 the building platform 30 is in contact with the bearing platform 21 when it is installed on the transport vehicle 10, so that the building platform 30 is more flat. Secondly, the inlay column 37 is inlaid on the bearing platform 21 during installation, and an inlay hole is provided on the bearing platform 21. , so that the surfaces of the inlay hole and the inlay column 37 are in contact during inlaying. At the same time, since a buffer groove is provided on the inlay column 37, an elastic plate is obliquely arranged in the buffer groove, and then when the inlay column 37 is placed in the inlay hole, the elastic plate on the inlay column 37 is squeezed through the inner wall of the inlay hole and then shrinks into the buffer groove. When the inlay column 37 completely enters the inlay hole, the reaction force of the elastic plate makes the elastic plate have an outward expansion force, so that the elastic plate abuts against the inner wall of the inlay hole, and then the inlay column 37 is inlaid in the inlay hole, so that the connection between the inlay column 37 in the inlay hole and the supporting platform 21 is more firmly connected, and then the connection between the supporting platform 21 and the building platform 30 is more firmly connected. Secondly, it is also more convenient to remove the building platform 30 from the supporting platform 21 during disassembly.

[0049] 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, which is arranged on the transport base 20, and a connecting groove is opened on the side of the mounting plate 51 close to the transport base 20; a hydraulic lifting rod 52, which is arranged in the connecting groove, and the hydraulic lifting rod 52 performs telescopic movement in the vertical direction; a hydraulic extension rod 53, which 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 entire test cabin is lifted and disassembled by the hydraulic lifting rod 52 and the hydraulic extension rod 53.

[0050] Figure 3 and Fig.13An electromagnetic compatibility outdoor test cabin is implemented in the present invention. The disassembly device 50 is formed by a mounting plate 51, a hydraulic lifting rod 52 and a hydraulic extension rod 53. The building platform 30 is propped up by the hydraulic lifting rod 52 to separate the building platform 30 from the transport base 20. After propping up, the building platform 30 is extended toward the side wall of the transport vehicle 10 by the hydraulic extension rod 53. When the building platform 30 is extended outward by the hydraulic extension rod 53, a placement groove is opened at the bottom of the building platform 30 corresponding to the hydraulic extension rod 53, and one end of the placement groove passes through the edge of the building platform 30, and the other end is 30 cm away from the edge. When the hydraulic extension rod 53 is extended, the extension end is against the closed end of the placement groove to push the building platform 30 toward one side of the vehicle. The vehicle 30 is moved and the building platform 30 is moved out of the vehicle, so that the bottom of the building platform 30 is facing the ground, and the hydraulic lifting rod 52 is slowly retracted to make the building platform 30 descend. When it is retracted to the limit, the electric telescopic rod 36 under the building platform 30 is started to extend the electric telescopic rod 36 downward until it touches the ground to support the building platform 30. Then, the hydraulic lifting rod 52 and the hydraulic extension rod 53 are evacuated to place the building platform 30 on the ground, so as to facilitate the vehicle to be tested to enter the test cabin and facilitate on-site vehicle testing. The hydraulic lifting rod 52 and the hydraulic extension rod 53 are connected to the circuit system of the vehicle, and the operation of the hydraulic lifting rod 52 and the hydraulic extension rod 53 is controlled by the vehicle's control panel.

[0051] Usage process: When in use, the building platform 30 is installed on the transport base 20 on the transport vehicle 10, and then a multi-section telescopic rod 34 is placed on the building platform 30, and the shielding plate 40 is assembled and spliced ​​through the multi-section telescopic rod 34, so that the shielding plate 40 is combined on the building platform 30 to form a test cabin. When assembling the shielding plate 40, a shielding block 423 is first laid on one side of the shielding plate 40, and the shielding plate 40 is shielded by the shielding block 423, which can better separate and block the electromagnetic waves inside the cabin and the electromagnetic waves outside, so that the detected data is more accurate. Secondly, during assembly, the annular airbag 33 and the abutment strip 321 arranged on the building platform 30 interact with each other. 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 the shielding plate 40 is assembled, the top sealing plate 43 is embedded and installed on the top, thereby forming a sealed and well-shielded electromagnetic test cabin, and then it is transported and opened by the transport vehicle 10. Field inspections are carried out in various areas. During the inspection, the inspection can be carried out on the vehicle or on the ground. When inspecting on the vehicle, the electromagnetic compatibility of the accessories of the new energy vehicle is inspected. When inspecting on the ground, the electromagnetic compatibility performance of the whole vehicle is inspected. The inspection cabin needs to be removed from the vehicle. When disassembling, the building platform 30 is moved down from the transport vehicle 10 through the disassembly device 50, so that the disassembly is more convenient. The inspection is carried out by assembly. The assembly is the same as the assembly on the vehicle, except that the ground needs to be leveled with an electric telescopic rod 36 so that it can be applied to different terrains. After leveling, electromagnetic compatibility inspection is carried out. At the same time, the support member 322 is set to prop up the wheels of the vehicle when the vehicle is inspected, so that the vehicle is in a running state during the inspection process, and the electromagnetic anti-interference data of the vehicle during operation can be obtained, thereby solving the problem that the existing new energy vehicles cannot be inspected on the spot, the test cabin cannot be moved, cannot be built and disassembled outdoors, and can only be fixed in a specific position for use.
