Description

Technical Field

[0001] This utility model belongs to the field of small and lightweight structures, and relates to a small, heavy-load, ultra-lightweight adapter device for a high-power transmission system. Background Technology

[0002] In anti-interference testing, the testing against high-power microwave interference signals is particularly important. Previously, high-power radiated interference exceeding 50kW was typically handled using vehicle-mounted high-power transmitters. However, this approach is not only costly but also difficult to implement in distributed, rapid deployment. Achieving portable, miniaturized setups for high-power radiation increases the size and weight of the power amplifier and antenna, exceeding 60kg. Simultaneously, real-time pointing and tracking by the servo turntable is required, placing stringent demands on the overall weight, size, and load-bearing capacity. The adapter frame, responsible for connecting the servo turntable to the power amplifier and antenna, is a crucial component. The adapter frame itself must typically weigh less than 6kg, while possessing strong rigidity, portability, and conformity to the rotational center of gravity. It must bear the heavy loads of the power amplifier and antenna while being stably mounted on the servo turntable, ensuring stable and reliable operation of the entire system. Conventional adapter frame devices cannot meet the requirements of high-power transmission systems. While meeting the heavy load and connection requirements, the adapter frame itself would be overweight; conversely, if its weight were sufficient, it would not be able to stably support the heavy loads and ensure interface compatibility and interconnection. Utility Model Content

[0003] The technical problem solved by this utility model is to overcome the shortcomings of the prior art and provide a small, heavy-load, ultra-lightweight adapter device for a high-power transmission system.

[0004] The solution of this utility model is: a small, heavy-load, ultra-lightweight adapter frame device for a high-power transmission system, including a carbon fiber frame, a servo adapter structure, an antenna adapter structure, a power amplifier mounting structure, a detection and tracking mounting hole, and a directional mounting structure; the carbon fiber frame includes crossbeams, baffles, and short crossbeams; upper and lower crossbeams are placed parallel to each other on the upper and lower sides of the center of the carbon fiber frame, and four baffles are perpendicularly connected to two crossbeams respectively, and the short crossbeams connect two intermediate baffles; the servo adapter structure is located between the two crossbeams and connected to the two intermediate baffles; the directional mounting structure is fixed on the servo adapter structure; the antenna adapter structure and the power amplifier mounting structure are distributed on the four baffles of the carbon fiber frame.

[0005] The short crossbeams include a first short crossbeam, a second short crossbeam, and a third short crossbeam. The first and third short crossbeams are located on opposite sides of the center of the carbon fiber frame and are symmetrical in position. The second and first short crossbeams are located on the same side of the center of the carbon fiber frame. The detection and tracking mounting hole is located at the center of the first short crossbeam.

[0006] The four baffles of the carbon fiber frame are designed with a hollowed-out shape, and the hollowed-out area accounts for 50% to 60% of the total baffle area.

[0007] The servo adapter structure includes two sets of adapter blocks, which are symmetrically placed on both sides of the center of the carbon fiber frame. The upper end face of the adapter block is connected to the middle section of the crossbeam plate on the carbon fiber frame, and the lower end face is suspended. It is connected to the two baffles in the middle facing the center side respectively. A rectangular vertical groove with an opening at the bottom is opened on the center side of the adapter block for sliding and hanging on the servo turntable flange from bottom to top.

[0008] The two sets of adapter blocks are equipped with symmetrical fixing posts for fixing the guide installation structure.

[0009] The antenna adapter structure includes four sets of antenna fasteners, located on the outer sides of two baffles on the same side of the center of the carbon fiber frame.

[0013] The power amplifier blade module mounting slot is located at one end of the front side of the carbon fiber frame, with a stop block at the other end.

[0014] The advantages of this utility model compared with the prior art are:

[0015] (1) This utility model adopts an integrated design of carbon fiber frame. Compared with aluminum alloy, carbon fiber has the characteristics of light weight, high strength and high temperature resistance.

[0023] The present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, a small, heavy-load, ultra-lightweight adapter device for a high-power transmission system includes a carbon fiber frame 1, a servo adapter structure 2, an antenna adapter structure 3, a power amplifier mounting structure 4, a detection and tracking mounting hole 5, and a directional mounting structure 6. The carbon fiber frame 1 adopts an integrated design, which on the one hand supports all the load equipment such as the detection and tracking module, the directional module, the array antenna, and the power amplifier; on the other hand, it ensures stable interconnection with the servo turntable, ensuring the entire system is stably mounted on the servo turntable. The detection and tracking mounting hole 5 allows the detection and tracking module to be installed on the carbon fiber frame 1; the directional mounting structure 6 allows the directional module to be installed on the carbon fiber frame 1; the antenna adapter structure 3 allows the array antenna to be installed on the carbon fiber frame 1; the power amplifier mounting structure 4 allows the power amplifier to be installed on the carbon fiber frame 1; and the servo adapter structure 2 ensures reliable interconnection between the carbon fiber frame 1 and the servo turntable.

[0025] like Figure 2 , Figure 3As shown, a small, heavy-duty, ultra-lightweight adapter frame device for a high-power transmission system includes a carbon fiber frame 1, a servo adapter structure 2, an antenna adapter structure 3, a power amplifier mounting structure 4, a detection and tracking mounting hole 5, and a guiding mounting structure 6. The servo adapter structure 2 includes two sets of symmetrically placed adapter blocks 21; the antenna adapter structure 3 includes four sets of antenna mounting components; the power amplifier mounting structure 4 includes four sets of power amplifier mounting components; and the guiding mounting structure 6 includes two symmetrically placed fixing posts.

[0026] The entire adapter frame is made of carbon fiber, weighing less than 6 kg, which is 3.5 kg lighter than 2A12 aluminum alloy. It employs RTM (Resin Transfer Molding) molding, using a pair of male and female molds to seal the liquid resin during filling, impregnation, and thermosetting. Furthermore, to reduce the weight of the carbon fiber frame 1 without compromising its strength, the four baffles are hollowed out, with the hollowed-out area accounting for 50%–60% of the total baffle area.

[0027] like Figure 4 As shown, the carbon fiber frame 1 includes crossbeams, baffles, and short crossbeams. Upper and lower crossbeams are placed parallel to each other on the upper and lower sides of the center of the carbon fiber frame 1. A notch is reserved on the rear side of the middle section of the lower crossbeam to avoid affecting the installation of the servo turntable flange and the servo adapter structure 2. Four baffles and two crossbeams are placed vertically. To match the interface with the power amplifier mounting structure 4, the four baffles are set at different heights. The two baffles located on the same side of the center are at the same height and have flush end faces. If the overall weight allows, the four baffles can also be at the same height. To ensure the strength and stability of the carbon fiber frame, three short crossbeams are also set between the two middle baffles, including a first short crossbeam, a second short crossbeam, and a third short crossbeam. The first and third short crossbeams are located on opposite sides of the center of the carbon fiber frame 1 and are symmetrically positioned. The second short crossbeam is located on the same side of the center of the carbon fiber frame 1 as the first short crossbeam.

[0028] The detection and tracking mounting hole 5 is located at the center of the first short crossbeam of the carbon fiber frame 1, and the detection and tracking module can be fixedly installed by screws.

[0029] The servo adapter structure 2 includes two sets of symmetrically placed adapter blocks 21, located on the center sides respectively. The upper end of the adapter block 21 is connected to the middle section of the first crossbeam plate above the carbon fiber frame 1, and the lower end is suspended and connected to the center side of the two middle baffles respectively.

[0030] like Figure 5The diagram shows a cross-sectional view of the servo adapter structure 2. The adapter block 21 has a rectangular vertical groove 22 on its center-facing side that matches the servo turntable flange. The top and outer sides of the rectangular vertical groove 22 are stop blocks, and the bottom is open. During assembly, the servo turntable flange is located behind the carbon fiber frame 1. The bottom opening of the rectangular vertical groove 22 is aligned with the upper surface of the vertically placed servo turntable flange. The carbon fiber frame 1 is then slidably mounted on the servo turntable flange from bottom to top until the upper surface of the servo flange contacts the top stop block, thus completing the reliable connection between the entire carbon fiber frame 1 and the servo turntable.

[0031] The antenna adapter structure 3 includes four sets of antenna fixing components, located on the outer sides of two baffles on the same side of the center of the carbon fiber frame 1. One set is located above the upper crossbeam, and the other set is located below the lower crossbeam. Each set of antenna fixing components includes two symmetrically placed pin-hole positioning lugs 31. Each pin-hole positioning lug 31 is provided with a positioning hole 311 and a locking hole 312. The positioning hole 311 is a through hole used for positioning the array antenna. The locking hole 312 is provided with an internal thread for fixing the array antenna. During installation, the array antenna subarray is located in front of the carbon fiber frame 1. First, positioning pins are used to pass through the positioning holes 311 and the positioning holes on the array antenna subarray in sequence. After both pin-hole positioning lugs 31 in one set are positioned, screws are used to pass through the locking holes 312 and the locking holes on the array antenna subarray in sequence for fixing. After both pin-hole positioning lugs 31 in one set are locked, screws are used to pass through the two antenna fixing holes 32 located on the crossbeam of the carbon fiber frame 1 to further tighten the array antenna subarray.

[0032] The amplifier mounting structure 4 includes four sets of amplifier mounting components, located on the inner sides of two baffles on the same side of the center of the carbon fiber frame 1. One set is located above the upper crossbeam, and the other is located below the lower crossbeam. Each set of amplifier mounting components includes four amplifier blade module mounting slots 41 and eight amplifier locking holes 42. Taking one set as an example, two amplifier blade module mounting slots 41 are symmetrically located on the inner sides of the two baffles on one side of the center of the carbon fiber frame 1, one pair above and one pair below. The vertical spacing between the two sets is determined according to the size of the amplifier blade module. The amplifier locking holes 42 are threaded holes formed on the amplifier blade module mounting slots 41. The blade module mounting slots 41 are open at the front and have a stop at the rear. During installation, the amplifier blade module slides from the front of the carbon fiber frame 1 to the rear, and when it reaches the stop, it is locked by a locking pin passing through the amplifier locking holes 42 to prevent the amplifier blade module from falling off when the unit is rotated. The dimensions of the mounting slots are designed as follows: To ensure smooth installation of the power amplifier blade modules, the mounting slot positions for each group differ to match the power amplifier blade modules. In this embodiment, among the four power amplifier mounting structures, the two diagonally located power amplifier mounting structures 4 are centrally symmetrical. Depending on the different sizes of the power amplifier blade modules, the mounting slot positions can also be set to be the same.

[0033] like Figure 3 As shown, the guide mounting structure 6 is located behind the servo adapter structure 2 and includes two symmetrically placed fixing posts. The fixing posts are provided with threaded holes, and the guide module can be installed and fixed by screws.

Any person skilled in the art can make possible changes and modifications to the technical solution of the present invention by utilizing the methods and techniques disclosed above without departing from the spirit and scope of the present invention.
