[0002] At present, electromagnetic shielding shelters are widely used in daily life. For the cabin wall panels of electromagnetic shielding shelters, inner skin and outer skin are usually used on the inner and outer sides of the frame, and a sandwich layer is set between the inner and outer skins. The cabin wall panels of traditional shelters are often made of alloy materials such as aluminum alloy, magnesium alloy, and titanium alloy, while the sandwich layer is usually made of plastic honeycomb panels, foam panels and other materials.

[0003] For expandable shelters, due to the relative movement between the expansion sub-cabin and the shelter main body, gaps will inevitably appear between the expansion sub-cabin and the shelter main body, and these gaps will cause electromagnetic radiation to leak, thereby affecting the electromagnetic shielding performance of the shelter and reducing the electromagnetic shielding performance of the shelter.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0030] like Figures 1 to 8 As shown, the utility model is a high-performance electromagnetic shielding cabin, comprising: a main cabin 1, an auxiliary cabin 2, the auxiliary cabin 2 is movably mounted in the inner cavity of the main cabin 1, a mounting seat 3, the mounting seat 3 is located at the bottom of the main cabin 1 and the auxiliary cabin 2, and the bottom of the main cabin 1 and the top of the mounting seat 3 are fixedly connected, a moving mechanism for driving the main cabin 1 and the auxiliary cabin 2 to expand, a positioning mechanism for positioning the main cabin 1 and the auxiliary cabin 2 after movement, and a sealing mechanism for sealing the main cabin 1 and the auxiliary cabin 2;

[0031] The moving mechanism includes: a hydraulic rod 4 fixedly installed on the inner wall of the mounting seat 3, a connecting plate 6 fixedly installed at the bottom of the auxiliary cabin 2, the side wall of the connecting plate 6 is fixedly connected to the movable end of the hydraulic rod 4, a guide rail 5 fixedly installed at the bottom of the inner cavity of the mounting seat 3, both sides of the guide rail 5 are inclined near the top, a mounting rod 7 fixedly installed at the bottom of the auxiliary cabin 2, and a pulley 8 rotatably installed at the bottom end of the mounting rod 7, the outer edge of the pulley 8 is provided with an annular groove, and the annular groove is adapted to the outer edge of the guide rail 5.

[0032] When in use, the connecting plate 6 can be driven to move by starting the extension of the hydraulic rod 4, and the connecting plate 6 drives the auxiliary cabin 2 to move outside the inner cavity of the main cabin 1, so that the main cabin 1 and the auxiliary cabin 2 can be expanded. When the auxiliary cabin 2 moves, the mounting rod 7 is driven to move by the auxiliary cabin 2, and the pulley 8 is driven to roll along the path direction of the guide rail 5 by the mounting rod 7. Since the path direction of the guide rail 5 is consistent with the extension direction of the hydraulic rod 4, the auxiliary cabin 2 can maintain the movement in a straight line, avoiding the displacement of the auxiliary cabin 2 during the movement.

[0033] Since there are two hydraulic rods 4, guide rails 5, and pulleys 8 in the moving mechanism, and they are symmetrically located at the bottom of the auxiliary cabin 2, both sides of the auxiliary cabin 2 can be evenly supported, thereby ensuring the stability of the auxiliary cabin 2 during movement and ensuring smooth expansion operations of the auxiliary cabin 2.

[0034] It should be added here that both sides of the guide rail 5 are inclined near the top, and an annular groove is provided on the outer edge of the pulley 8, which is matched with the outer edge of the guide rail 5, thereby preventing the pulley 8 from detaching from the guide rail 5 during movement, further ensuring the stability of the auxiliary cabin 2 during movement, and ensuring the smooth expansion operation of the auxiliary cabin 2.

[0035] The positioning mechanism includes: a mounting groove three opened on the top of the auxiliary cabin 2, a linkage bar 10 movably installed in the inner cavity of the mounting groove, a linkage spring 9 fixedly installed between the bottom of the linkage bar 10 and the inner wall of the mounting groove three, a bull's eye ball 11 rotatably installed on the top of the linkage bar 10, and a positioning groove opened on the top of the inner cavity of the main cabin 1.

[0036] During the expansion and movement of the auxiliary cabin 2, the linkage bar 10 can be driven to move, and the linkage bar 10 can drive the bull's eye ball 11 to move. Due to the elastic force of the linkage spring 9, the bull's eye ball 11 abuts against the top of the inner cavity of the main cabin 1, so that the bull's eye ball 11 rolls along the top of the inner cavity of the main cabin 1. When the bull's eye ball 11 rolls to the inner cavity of the positioning groove, the main cabin 1 and the auxiliary cabin 2 can be positioned, and the expansion of the auxiliary cabin 2 is completed at this time.

[0037] Since the cross-section of the positioning groove is designed to be a right-angled trapezoid, that is, the side of the side wall of the positioning groove close to the first sealing strip 14 is inclined, and the side away from the first sealing strip 14 is vertical, when the bull's eye ball 11 rolls along the top of the inner cavity of the main cabin 1 into the positioning groove, it first gradually enters the inner cavity of the positioning groove along the inclined side wall of the positioning groove. Due to the elastic force of the linkage spring 9, the bull's eye ball 11 can always be in contact with the inner wall of the positioning groove. When the linkage strip 10 is in contact with the vertical inner wall of the positioning groove, the expansion of the main cabin 1 and the auxiliary cabin 2 is completed. Through the mutual cooperation of the linkage strip 10 and the positioning groove, the auxiliary cabin 2 can be positioned after moving, thereby avoiding the separation of the main cabin 1 and the auxiliary cabin 2.

[0038] The sealing mechanism includes: a mounting groove 1 and a mounting groove 2 opened on the inner wall of the main cabin 1, a first sealing strip 14 movably installed in the inner cavity of the mounting groove 1, a second sealing strip 15 movably installed in the inner cavity of the mounting groove 2, an airbag 12 which is inclined and fixedly installed on the inner wall of the mounting groove 1 and the mounting groove 2 on one side close to the first sealing strip 14 and the second sealing strip 15, one side of the airbag 12 is fixedly connected to the inner wall of the adjacent mounting groove 1 or the mounting groove 2, and the other side is fixedly connected to one side of the adjacent first sealing strip 14 or the second sealing strip 15, a reset member for driving the first sealing strip 14 and the second sealing strip 15 to reset, and an air pump 16 for filling and extracting gas from the airbag 12, the air pump 16 is fixedly installed on the side wall of the main cabin 1, and the air pump 16 is connected to several airbags 12 through connecting pipes.

[0039] When the expansion and movement of the auxiliary cabin 2 is completed, the air pump 16 is started to transport air to the inner cavities of the plurality of airbags 12 through the connecting pipe. As the inner cavities of the airbags 12 are expanded after being filled with air, the adjacent first sealing strip 14 or second sealing strip 15 can be squeezed, so that the first sealing strip 14 and the second sealing strip 15 move toward the side close to the auxiliary cabin 2.

[0040] Since an annular groove is provided on the outer edge of the auxiliary compartment 2, two first sealing strips 14 are provided, and are arranged up and down, and two second sealing strips 15 are provided, and are arranged left and right, so that under the extrusion of the airbag 12, the two first sealing strips 14 and the second sealing strips 15 are both inserted into the inner cavity of the annular groove. When the first sealing strip 14 and the second sealing strip 15 are close to the side of the auxiliary compartment 2 and abut against the inner wall of the annular groove, the sealing between the main compartment 1 and the auxiliary compartment 2 can be completed;

[0041] Since the side where the first sealing strip 14 and the second sealing strip 15 are close to each other is inclined, and the inclination angle is 45 degrees, when the side where the first sealing strip 14 and the second sealing strip 15 are close to the auxiliary cabin 2 abuts against the inner wall of the annular groove, the sides where the first sealing strip 14 and the second sealing strip 15 are close to each other abut against each other, so that the two first sealing strips 14 and the two second sealing strips 15 form a complete rectangular sealing ring, and the rectangular sealing ring can fill the gap between the main cabin 1 and the auxiliary cabin 2, thereby effectively avoiding the leakage of electromagnetic radiation and effectively improving the electromagnetic shielding performance of the cabin, thereby making the device have superior electromagnetic shielding performance, simple structure, and high practicality, and solving the problem that the inevitable gaps in the expandable cabin cause electromagnetic wave leakage and affect the electromagnetic shielding effect of the cabin.

[0042] The reset member includes: a fixed tube 13 respectively fixedly installed on the inner walls of the mounting groove 1 and the mounting groove 2, a movable tube 17 movably installed in the inner cavity of the fixed tube 13, one end of the movable tube 17 fixedly connected to one side of the adjacent first sealing strip 14 or the second sealing strip 15, and a reset spring 18 fixedly installed between the fixed tube 13 and the inner cavity of the movable tube 17.

[0043] When the airbag 12 expands and drives the first sealing strip 14 or the second sealing strip 15 to move, it can drive the movable tube 17 to move, and the movable tube 17 drives the reset spring 18 to stretch. When the expandable cabin is used, the air pump 16 is started again to extract the air from the inner cavities of several airbags 12, so that the airbag 12 has no squeezing effect on the first sealing strip 14 or the second sealing strip 15. At this time, the elastic force of the reset spring 18 can drive the first sealing strip 14 or the second sealing strip 15 to reset, thereby not affecting the movement of the auxiliary cabin 2 to the inner cavity of the main cabin 1, and preparing for reuse.

[0044] Working principle: When in use, by starting the air pump 16, air can be transported to the inner cavities of several airbags 12 through the connecting pipe. Since the inner cavity of the airbag 12 expands after being filled with air, the adjacent first sealing strip 14 or second sealing strip 15 can be squeezed, so that the first sealing strip 14 and the second sealing strip 15 move to the side close to the auxiliary cabin 2. Under the squeezing action of the airbag 12, the two first sealing strips 14 and the second sealing strip 15 are inserted into the inner cavity of the annular groove. When the first sealing strip 14 and the second sealing strip 15 are close to the side of the auxiliary cabin 2 and abut against the inner wall of the annular groove, the sealing between the main cabin 1 and the auxiliary cabin 2 can be completed, thereby effectively avoiding the leakage of electromagnetic radiation and effectively improving the electromagnetic shielding performance of the cabin, so that the device has superior electromagnetic shielding performance, simple structure, and high practicality, which solves the problem that the inevitable gaps in the expandable cabin cause electromagnetic wave leakage and affect the electromagnetic shielding effect of the cabin.
