The support provides elastic support through the connecting pad and the support legs. The damping structure uses an inclined damper to disperse stress and vibration. The elevation adjustment mechanism realizes precise adjustment of the reflective surface through the rotating shaft and the fixed wheel.
This design effectively slows down vibration, maintains the stability of the overall structure, and improves the interference effect of the laser emission optical part on the target area through precise elevation adjustment, so as to avoid the interference effect being reduced due to deviation of the aiming area.

Figure 6 and Figure 7 The three-dimensional structures of the base and the bracket are shown respectively.
[0026] Example 1.
[0027] Preferably, the high-power jamming antenna applies the principle and main structure of the Cassegrain antenna, including a reflective surface 100 and a laser emission optical part, a beam deflection component, a receiving adjustment part and other structures located on the reflective surface 100. The high-power jamming antenna also includes:
[0028] The support 120 includes a support plate 121 and a plurality of connection pads 122 and a plurality of support legs 123 located on the same side of the support plate 121. One end of each connection pad 122 is elastically connected to the support plate 121, and the other end of each connection pad 122 is elastically connected to the (corresponding) support leg 123; so that the support 120 has a basic ability to reduce vibration;
[0029] The damping structure 200 is located between the connecting seat 110 and the support 120. The damping structure 200 includes a plurality of obliquely arranged dampers 210. Each damper 210 includes a plurality of rigid sections 211 and a plurality of damping sections 212. The rigid sections 211 and the damping sections 212 are alternately arranged. The damping sections 212 are elastically connected to the adjacent rigid sections 211, so that the damper 210 maintains the necessary rigidity to support the stability of the overall structure. At the same time, the plurality of damping sections 212 can disperse stress and vibration in sections. The plurality of dampers 210 can maintain reasonable redundancy. Assuming that an individual damper 210 fails, the overall structure can still be kept stable, so that the damping structure 200 has the ability to further reduce vibration.
[0030] See attached figure Figure 6-7 , wherein the high-power interference antenna further includes an elevation angle adjustment mechanism 300, and the elevation angle adjustment mechanism 300 includes:
[0031] The base 310 includes a backing plate 313, a base body 311, and (two) base arms 312 integrally formed with the base body 311. The backing plate 313 is fixedly connected to the base body 311 and the base arms 312, so that the backing plate 313, the base body 311, and the base arms 312 together form an opening for partially accommodating the bracket 320.
[0032] The bracket 320 has one side fixedly connected to the reflecting surface 100, and the other side of the bracket 310 is rotatably connected to the base 310, so that the bracket 310 can rotate around the rotating shaft 321 relative to the base 310, thereby driving the angle of the reflecting surface 100 relative to the base 310 to change, thereby adjusting the elevation angle of the high-power jamming antenna, so that the laser emission optical part can be more accurately aimed at the target area, thereby improving the jamming effect on the target area, avoiding excessive deviation between the aiming area of the laser emission optical part and the target area, and greatly weakening the jamming effect.
[0033] Among them, the bracket 320 includes a rotating shaft 321 and a fixed wheel 322 which is sleeved on and fixedly connected to the rotating shaft 321. The bracket 320 also includes a counterweight plate 323. A plurality of connecting rods 324 are arranged between the counterweight plate 323 and the fixed wheel 322. One end of each connecting rod 324 is fixedly connected to the fixed wheel 322, and the other end of each connecting rod 324 is fixedly connected to the counterweight plate 323. A plurality of slots (not shown in the figure) are arranged at the junction of the rotating shaft 321 and the base arm 312, so that when the rotating shaft 321 rotates relative to the base arm 312, it can be inserted into adjacent slots, so that the rotating shaft 321 and the base arm 312 can maintain both relative rotation and relative stability, thereby preventing slippage and causing instability of the reflecting surface 100.
[0034] Among them, the bracket 320 also includes a plurality of auxiliary connecting rods 325, one end of each auxiliary connecting rod 325 is fixedly connected to the rotating shaft 321, and the other end of each auxiliary connecting rod 325 is fixedly connected to the counterweight plate 323, so that the elevation angle of the high-power jamming antenna can be continuously kept stable, thereby preventing the laser emission optics from deviating from the target area, thereby reducing the jamming effect.
[0035] The rotating shaft 321 is made of a high-strength rigid material so as to have sufficient rigidity to prevent the reflecting surface 100 from becoming unstable.
[0036] It is worth mentioning that the technical features such as the specific components of the rigid materials involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional means in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.
