Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
First aspect
The present invention provides a pit in an RCS microwave darkroom in a first aspect, and for convenience of description, as shown in fig. 1 to 3, the present invention divides an inner space surrounded by the pit into a first region 1 and a second region 2;
the first area 1 is provided with a bottom slide rail (not marked in the figure), a lodging metal bracket 11 and a cover plate; the bottom sliding rail is arranged at the bottom of the first area 1; the lodging metal bracket 11 is connected to the bottom sliding rail in a sliding manner; the cover plates comprise an overturning cover plate 12 and a sliding cover plate 13, wave-absorbing materials 14 are covered on the overturning cover plate 12 and the sliding cover plate 13, and the length of the sliding cover plate 13 is not less than that of the second area 2; the flip cover 12 is far away from the second area 2, and the sliding cover 13 is close to the second area 2; the turnover cover plate 12 can be turned over along the edge of the pit; the sliding cover 13 can slide between the first area 1 and the second area 2;
the second area 2 is arranged with a support table 21 for placing a foam holder 22.
The indoor RCS test field mainly utilizes a metal shielding shell and a wave-absorbing material 14 as a structure to stabilize an electromagnetic environment. The metal shielding shell can protect the test field from external intentional or unintentional electromagnetic signals, and the wave-absorbing material 14 laid in the metal shell is used for solving the problem of reflection of electromagnetic waves in the shell. Two supporting mechanisms, namely a foam bracket 22 and a metal bracket, are usually arranged in a microwave darkroom, and the two supporting mechanisms have different application fields and cannot be replaced mutually, so that the brackets are usually required to be replaced for RCS testing. When the space in the dark room is narrow, a pit needs to be dug downwards for placing the metal support. However, the conventional replacement method requires manual handling of the absorbing material 14, which results in the change of the layout of the absorbing material 14 in the darkroom, and the metal plate in the pit and the turntable on which the foam holder 22 is placed are exposed, because these areas are located right below the quiet zone, and are strongly coupled with the target.
The invention carries out the following optimized design on the pit in the RCS microwave darkroom, and realizes the excellent improvement effect:
the first area 1 is a space for placing the lodging metal brackets 11, the second area 2 is a space for placing the foam brackets 22, and the spaces for placing the lodging metal brackets 11 and the foam brackets 22 are mutually independent, which is the basis of the pit design of the invention. On the basis, the cover plate and the lodging metal bracket 11 are designed, so that the operation of replacing the bracket is optimized, and the fixed clutter introduced by the bracket is weakened, so that the RCS test performance is improved.
The cover plate of the invention comprises a turnover cover plate 12 and a sliding cover plate 13, wherein the turnover cover plate 12 can be turned over along the edge of the pit, and the sliding cover plate 13 can slide between the first area 1 and the second area 2. When it is desired to use the lodging metal brackets 11 for testing, the flip cover 12 is flipped up and the sliding cover 13 is slid to the second area 2, thereby providing sufficient space for the lifting of the lodging metal brackets 11 in the pit. In the process of lifting the lodging metal brackets 11, considering the limit of the height of the pit and the limit of the length of the turnover cover plate 12, the height of the lodging metal brackets 11 is lifted by utilizing the height-variable property of the lodging metal brackets 11, the lodging metal brackets 11 are moved out of the first area 1 by utilizing the bottom slide rail and move towards the second area 2, so that the lodging metal brackets 11 are smoothly lifted, and a space is provided for the falling of the turnover cover plate 12. When the flip cover 12 has enough space to flip downwards to the horizontal state, the flip cover 12 is flipped downwards to the horizontal state to cover the pit (at this moment, partial covering), and the sliding cover 13 slides to the second area 2, at this moment, the flip cover 12 and the sliding cover 13 cover the exposed pit which may be caused originally, so that the exposure of the metal plate in the pit and the support platform 21 for placing the foam bracket 22 is avoided.
When the foam support 22 is needed to be used for testing, the turnover cover plate 12 is turned upwards, then the lodging metal support 11 is lodged in the pit, then the turnover cover plate 12 is turned downwards to be in a horizontal state, and the sliding cover plate 13 is slid to the first area 1. At this time, the flip cover 12 and the slide cover 13 cover the pit of the second area 2, the support base 21 is exposed, and the foam holder 22 is placed on the support base 21.
Specifically, the lateral walls on both sides of the pit are provided with lateral wall slide rails, and the sliding cover plate 13 is connected with the lateral wall slide rails in a sliding manner. The sliding of the sliding cover 13 in the first area 1 and the second area 2 is achieved by providing side wall slide rails on the side walls of the pit.
It should be noted that the description of the bottom slide rail and the side wall slide rail is used to describe the positions of the slide rails and distinguish the two, the existing slide rail structures can be used as the bottom slide rail and the side wall slide rail of the present invention, and the existing technology can be used for how the lodging metal bracket 11 is slidably connected with the bottom slide rail and how the sliding cover plate 13 is slidably connected with the side wall slide rail.
In some embodiments, the support platform 21 is a height-fixed structure, and the support platform 21 has a height lower than the sliding cover 13, so as to ensure that the sliding cover 13 can move to the second area 2, thereby covering the pit in the second area 2.
In some embodiments, the support table 21 is a height-adjustable structure. For example, the supporting platform 21 includes a supporting body and a lifting platform fixed on the upper surface of the supporting body; when the foam support 22 is used, the foam support 22 is placed on the lifting platform, and the height of the lifting platform is adjusted to enable the height of the foam support 22 to meet the test requirement. When the lodging metal bracket 11 is required to be used, since the sliding cover 13 needs to be moved to the second region 2 to cover the supporting table 21, if the supporting table 21 is higher than the sliding cover 13, the height of the lifting platform is reduced.
In some embodiments, the lodging metal bracket 11 comprises a bracket body and a bracket base connected with the bracket body; the bracket body is movably connected with the bracket base in a connecting mode; the support base is connected with the bottom sliding rail in a sliding mode. It should be noted that the active connection is the prior art.

When the lodging metal bracket 11 is lifted up, after the lodging metal bracket is lifted to a designed angle (the angle is determined according to the test requirement), the bracket body is fixed by adopting the existing fixing method.
