[0024] refer to Figure 1-3 As shown, one embodiment of this utility model is as follows:

[0025] A shock-absorbing device for a photoelectric pod includes a connecting plate 1. The lower end of the connecting plate 1 is provided with a circular bracket 3 adapted to a photoelectric pod 2. The inner wall of the circular bracket 3 is provided with a mounting plate 4. The upper outer edge of the photoelectric pod 2 is provided with multiple mounting ears 5. The mounting plate 4 is provided with a through-hole 6 adapted to the mounting ears 5. The mounting plate 4 is provided with a mounting hole 7 on one side of the through-hole 6. A shock-absorbing ball 8 is provided between the mounting ears 5 and the mounting hole 7. The lower end of the connecting plate 1 is provided with multiple connecting springs 9. The lower end of the multiple connecting springs 9 is provided with a limiting plate 10 adapted to the photoelectric pod 2.

[0026] Specifically, the connecting plate 1 can be fixed to the fuselage skin by rivets; the lower end of the limiting plate 10 is provided with a soft pad 11, and the soft pad 11 has a gap with the upper end of the photoelectric pod 2.

[0027] During installation, the upper end of the shock-absorbing ball 8 is pre-fitted into the mounting hole on the mounting ear 5. Then, the photoelectric pod 2 is operated so that the mounting ear 5 passes through the through-notch 6 and is positioned above the mounting plate 4. After rotation and adjustment, it is positioned above the mounting hole on the mounting plate 4. Then, the lower end of the shock-absorbing ball 8 is fitted into the mounting hole 7 on the mounting plate 4 to realize the installation of the photoelectric pod.

[0028] The mounting lug 5 and the mounting plate 4 are connected by multiple shock-absorbing balls 8, which can effectively reduce the impact of aircraft vibration on the electro-optical pod and improve the image stability of the electro-optical pod. Furthermore, the shock-absorbing balls 8 are placed inside the circular mounting bracket 3, which protects them. A through-hole 6 is provided to position the shock-absorbing balls 8 above the mounting plate 4, keeping them in a downward-pressed state, reducing the risk of them falling off due to severe vibration and ensuring good stability. Simultaneously, this embodiment also uses a connecting spring 9 and a limiting plate 10 to restrict the upward movement of the electro-optical pod 2, further improving stability.

[0029] Furthermore, both the connecting plate 1 and the limiting plate 10 are provided with cable through holes 12 at their centers. The soft pads 11 include two, and the two soft pads 11 are respectively disposed on both sides of the cable through holes 12. The multiple connecting springs 9 are evenly distributed on the outside of the cable through holes 12.

[0030] The circular bracket 3 has a plurality of rectangular holes 13 symmetrically arranged on its side wall. A lifting groove 14 is formed between the two soft pads 11. The width of the rectangular hole 13 is greater than the width of the lifting groove 14. The radial direction of the lifting groove 14 is consistent with the direction of the line connecting any two symmetrical rectangular holes 13.

[0031] The lower end face of the limiting plate 10 is provided with lifting inclined surfaces 15 at both ends of the lifting groove 14.

[0032] While ensuring sufficient space for the upward movement of the photoelectric pod 2, the limiting plate should also facilitate disassembly and assembly operations. Therefore, this application implements the installation of the limiting plate by setting a connecting spring 9. The rectangular hole 13 effectively reduces the weight of the equipment while also facilitating the lifting of the limiting plate 10. Specifically, in implementation, two wedge-shaped blocks can be inserted through the rectangular hole 13 to support the limiting plate 10 and lift it upward, thereby expanding the upward movement space of the photoelectric pod 2 and facilitating disassembly and assembly operations. Specifically, the lower end of the rectangular hole 13 can be slightly higher than the position of the limiting plate 10 in the natural extension and retraction state of the connecting spring 9, so as to achieve a larger movement space when the photoelectric pod 2 moves upward. Therefore, this embodiment provides a lifting ramp 15 on the lower end surface of the limiting plate 10 so that the wedge-shaped blocks can more easily enter the lifting groove 14. In specific operation, care should be taken to avoid damage to the cables by the wedge-shaped blocks, which can be protected by attaching a soft pad to the front end of the wedge-shaped blocks.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
