[0051] The frame 1 has a card seat 11 at both the front and rear ends of the frame 1 , and a rotating shaft 12 is welded to the outer side of the card seat 11 .
[0052] Two bases 2 are symmetrically arranged front and back about the middle of the frame 1, and two lifting hydraulic cylinders 3 are symmetrically arranged left and right in the middle of the base 2. The tops of the two lifting hydraulic cylinders 3 are movably connected to the left and right sides of the middle of the bottom surface of the transition seat 31 respectively, and the top of the transition seat 31 is movably connected to the bottom of the truss 4. A deflection hydraulic cylinder 41 is fixedly provided on the outer side of the truss 4.
[0053] The shielding room 9 has a detection platform 91 disposed inside the shielding room 9 and a plurality of fixtures 92 fixedly disposed outside the detection platform 91 .
[0054] In this embodiment, extension frames 13 are fixedly provided on both sides of the frame 1. The outer sides of the extension frames 13 are movably connected to the movable ends of the deflection hydraulic cylinders 41. The connection positions of the deflection hydraulic cylinders 41 on the two extension frames 13 are respectively located above and below the axis of the rotating shaft 12.
[0055] The two deflection hydraulic cylinders 41 are movably installed at the diagonals of the two trusses 4, that is, the two deflection hydraulic cylinders 41 are set at the diagonals of the frame 1.

[0056] The two deflection hydraulic cylinders 41 extend and contract respectively, so as to enable the frame 1 to slide forward or backward along the axial direction of the rotating shaft 12 on the outer side of the truss 4 .
[0057] In this embodiment, a mounting seat 5 is fixedly provided on the top surface of the frame 1, a ball head 51 is movably connected in the middle of the mounting seat 5, a vertical rod 52 is fixedly provided on the top of the ball head 51, the top of the vertical rod 52 extends to the inner side of the shielding room 9, an adjusting hydraulic cylinder 6 is fixedly provided on the inner side of the top of the vertical rod 52, a mounting sleeve 61 is fixedly provided on the top movable end of the adjusting hydraulic cylinder 6, and the top of the mounting sleeve 61 is fixedly connected to the bottom of the detection table 91.
[0058] When the rack 1 is moving and / or deflecting, the mounting seat 5 starts to move under the drive of the rack 1. Due to the design of the ball head 51 and the vertical rod 52, the mounting seat 5 drives the ball head 51 to deflect. At this time, the vertical rod 52 and the adjusting hydraulic cylinder 6 cooperate to change the working position of the detection platform 91 in the shielding room 9.

[0061] The cooperation of the sealing plate 8 , the telescopic sealing sleeve 81 and the sealing seat 82 prevents the setting of the vertical pole 52 and other structures from affecting the sealing performance of the shielding room 9 .
[0062] In this embodiment, the front and rear ends of the base 2 are movably connected to the sliding rod 21, the left and right ends of the sliding rod 21 are slidably connected to the sliding seat 22, the bottom of the sliding seat 22 is slidably connected to the top of the base 2, the top of the sliding seat 22 is movably connected to the connecting rod 23, and the tops of the two connecting rods 23 are respectively movably connected to the left and right ends of the transition seat 31.
[0063] When the lifting hydraulic cylinder 3 changes the working height of the transition seat 31 on the base 2, the two lifting hydraulic cylinders 3 on the base 2 need to work together for lifting, and the slide rod 21, the slide seat 22 and the connecting rod 23 cooperate to improve the movement stability of the transition seat 31.

[0067] In this embodiment, a hatch 93 is movably connected to the right side of the shielding room 9, and a receiving antenna 94 is provided on the inner side of the shielding room 9. The receiving antenna 94 is electrically connected to a spectrum analyzer.
[0068] A method for using an electronic component EMC comprehensive test device includes the following steps:

An installation space needs to be reserved on the ground below the shielding room 9 for installing the base 2 and the truss 4 part of the structure. The electronic components to be detected are fixed on the detection table 91 by the clamps 92.
[0070] The two lifting hydraulic cylinders 3 on the base 2 cooperate to change the working height of the truss 4 during the lifting process.

[0071] The deflection hydraulic cylinders 41 on the two trusses 4 cooperate with each other to extend and retract, so that the frame 1 can be deflected clockwise or counterclockwise with the rotating shaft 12 as the center. The two deflection hydraulic cylinders 41 contract one and extend the other, so that the frame 1 cooperates with the base 11 and the rotating shaft 12 to slide axially on the sleeve 42.
[0072] The frame 1 slides or deflects in the front-to-back direction, deflects in the left-to-right direction, and rises and falls in the up-and-down direction to change the working position of the mounting seat 5. The vertical rod 52 cooperates with the adjustment hydraulic cylinder 6 to change the working height of the detection platform 91 in the shielding room 9. The vertical rod 52 is designed with the ball head 51 at the bottom and the docking ball 7 in the middle to complete the movement of the top of the vertical rod 52 inside the shielding room 9. In the above operations, the movement of the electronic components fixed on the detection platform 91 will produce impacts of different strengths and directions, thereby simulating whether the electronic components will leak abnormal electromagnetic signals or form interference under the influence of external forces in the dynamic environment of the vehicle.
