DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 6 As shown, this embodiment provides an automotive electronic darkroom embodiment based on radiation emission and radiation immunity testing.

[0026] An automotive electronic darkroom based on radiation emission and radiation immunity test comprises a sheet metal frame 1, a shielding shell 2 is laid on the outer side of the sheet metal frame 1, an observation room 3 is arranged on one side of the shielding shell 2, a plurality of absorbing sponges 4 are evenly fixedly installed on the inner wall of the sheet metal frame 1, a ferrite 5 is installed on the absorbing sponge 4, a test antenna 6 is installed on the bottom plate inside the sheet metal frame 1, a placing table 7 is installed on one side of the test antenna 6, a shielding door 8 is movably installed on the shielding shell 2, a fastening mechanism 9 is arranged on the shielding door 8, a plurality of fixing frames 10 are fixedly installed on the surface of the shielding door 8, a clamping plate 11 is movably installed inside the fixing frame 10, a plurality of hydraulic rods 12 are fixedly installed on the surface of the fixing frame 10, a first fixing rod 13 is fixedly installed on the output end of the hydraulic rod 12, a plurality of second fixing rods 14 connected to the first fixing rod 13 are fixedly installed on the bottom of the clamping plate 11, a plurality of clamping frames 15 used in conjunction with the second fixing rod 14 are fixedly installed on the surface of the shielding shell 2, and a sealing ring 16 is fixedly installed on the shielding door 8. Through the setting of the fastening mechanism 9, the shielding door 8 can be fastened for a second time. After the shielding door 8 is closed on the shielding shell 2, multiple hydraulic rods 12 are started at the same time to shrink their output ends and push the clamping plate 11 through the first fixed rod 13 and the second fixed rod 14, so that the clamping plate 11 is pushed out of the fixed frame 10 and inserted into the clamping frame 15 for clamping. After relying on the clamping of multiple clamping plates 11 and the clamping frame 15, the closed shielding door 8 is fastened for a second time to prevent the shielding door 8 that has been used for a long time from loosening and improve its closure tightness. At the same time, a sealing ring 16 is also installed on the shielding door 8, which can further improve the sealing effect and avoid electromagnetic wave leakage.

[0027] Springs 17 are fixedly installed on both sides of the first fixing rod 13, and an insertion rod 18 is fixedly installed on the spring 17. Slots 19 are opened on both sides of the second fixing rod 14. One end of the insertion rod 18 passes through the spring 17 and the first fixing rod 13 and engages with the slot 19. A support plate 20 is provided under the placement table 7, and a motor 21 is fixedly installed on the support plate 20. The output end of the motor 21 is fixedly connected to the bottom of the placement table 7. By setting the spring 17, the plug rod 18 and the slot 19, the first fixing rod 13 and the second fixing rod 14 are combined by plugging the plug rod 18 and the slot 19. Since the plug rod 18 is supported by the spring 17, the plug rod 18 can be pulled outward to separate one end of the plug rod from the slot 19, thereby separating the first fixing rod 13 and the second fixing rod 14. Finally, the card plate 11 can be taken out of the fixing frame 10, which is convenient for replacement when it is damaged. By setting the support plate 20 and the motor 21, starting the motor 21 to rotate its output end can drive the placement table 7 to rotate, thereby facilitating the angle adjustment of the items placed on the placement table 7.

[0028] Two guide rails 22 are symmetrically installed inside the sheet metal frame 1, and a push plate 23 is installed between the two guide rails 22. A plurality of threaded barrels 24 are arranged on the top of the push plate 23 and are movably installed through a rotating shaft. A screw 25 used in conjunction with the threaded barrel 24 is fixedly installed at the bottom of the support plate 20, and the surface of the threaded barrel 24 is provided with anti-skid patterns. Through the arrangement of the guide rails 22 and the push plate 23, the placement table 7 can be driven to move left and right, thereby adjusting the position of the object. Through the arrangement of the threaded barrel 24 and the screw 25, the rotation of the threaded barrel 24 can rely on its internal threads to drive the screw 25 to move up and down, and indirectly adjust the placement table 7 to move up and down, thereby facilitating the adjustment of the height of the object. By arranging anti-skid patterns on the surface of the threaded barrel 24, the friction of its surface can be increased, making it easier to rotate the threaded barrel 24.

[0029] In this embodiment, if Figure 1-Figure 6 As shown, the working process of an automotive electronic darkroom based on radiation emission and radiation immunity test provided by this embodiment is as follows:

[0030] After the shielding door 8 is closed on the shielding shell 2, multiple hydraulic rods 12 are started at the same time to shrink their output ends and push the clamping plate 11 through the first fixed rod 13 and the second fixed rod 14, so that the clamping plate 11 is ejected from the fixed frame 10 and inserted into the clamping frame 15 for clamping. After the clamping of multiple clamping plates 11 and the clamping frame 15, the closed shielding door 8 is tightened for a second time to prevent the shielding door 8 from being loosened after long-term use and improve its closure tightness. At the same time, a sealing ring 16 is also installed on the shielding door 8 to further improve the sealing effect. Starting the motor 21 to rotate its output end can drive the placement table 7 to rotate, thereby facilitating the angle adjustment of the objects placed on the placement table 7. Rotating the threaded barrel 24 can rely on its internal thread to drive the screw 25 to rise and fall, and can indirectly adjust the placement table 7 to rise and fall, thereby facilitating the height adjustment of the objects.

[0031] In summary, in this embodiment, according to an automotive electronic darkroom based on radiation emission and radiation immunity test of this embodiment, through the setting of the spring 17, the plug 18 and the slot 19, the first fixing rod 13 and the second fixing rod 14 are combined by plugging the plug 18 and the slot 19. Since the plug 18 is supported by the spring 17, the plug 18 can be pulled outward to separate one end of the plug from the slot 19, thereby separating the first fixing rod 13 and the second fixing rod 14. Finally, the card plate 11 can be taken out from the fixing frame 10, which is convenient for replacement when it is damaged. By setting the support plate 20 and the motor 21 Starting the motor 21 to rotate its output end can drive the placement table 7 to rotate, thereby facilitating the angle adjustment of the items placed on the placement table 7. Through the arrangement of the guide rail 22 and the push plate 23, the placement table 7 can be driven to move left and right, thereby adjusting the position of the items. Through the arrangement of the threaded barrel 24 and the screw 25, the threaded barrel 24 can be rotated to drive the screw 25 to move up and down by relying on its internal threads, and the placement table 7 can be indirectly adjusted to move up and down, thereby facilitating the adjustment of the height of the items. By arranging anti-slip grooves on the surface of the threaded barrel 24, the friction of its surface can be increased, making it easier to rotate the threaded barrel 24.

[0032] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0033] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
