DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, the utility model provides a visual acquisition device for an unmanned reconnaissance aircraft, including a fuselage 1 and a shock-absorbing seat 3. The bottom end of the fuselage 1 is fixedly connected to the shock-absorbing seat 3, and the anti-collision plate 6 at the front end of the base 2 is pressed against the ground. At this time, the anti-collision plate 6 is pressed against the telescopic rod 7 at the front end of the shock-absorbing seat 3, and the telescopic rod 7 cooperates with the spring 8 to push the slider 4 to slide in the slide groove inside the shock-absorbing seat 3, and the impact force is reduced during the sliding process. Finally, the upper pressing plate 5 and the lower pressing plate 9 on the outside of the shock-absorbing seat 3 limit the movement of the slider 4 inside the slide groove of the anti-collision plate 6, thereby protecting the camera module 12 from a violent collision when it contacts the ground.

[0024] Specifically, a square groove is provided at the front end of the shock absorbing seat 3, and the rotating shaft 10 rotates inside the shock absorbing seat 3, rotating the rotating seat 11 at the bottom end out of the shock absorbing seat 3 and extending outward through the rotating ring 14 outside the fixing rod 13.

[0025] Furthermore, an extension rod 22 is fixedly connected to the inner center position of the rotating ring 14, and the rotating ring 14 outside the fixed rod 13 extends outward, and the sliding seat 15 slides upward on the outside of the extension rod 22 at the inner center position of the rotating ring 14. At this time, the extension rod 16 drives the rotating arm 17 sleeved on the outside to rise.

[0026] Furthermore, a square groove is formed on the outer side of the fixing seat 18. By rotating the rotating rod 19 inside the square groove of the fixing seat 18, the bottom end of the rotating rod 19 is vertically attached to the top end of the square groove of the shock absorbing seat 3 under the action of gravity.

[0027] It is worth mentioning that the front end of the rotating arm 17 is connected to the camera 20 through a buckle, and the outer side of the camera 20 is set to be a hydrophobic material. When used outdoors, rainy weather will not cause the camera 20 to fail to work normally.

[0028] It is worth noting that the bottom end of the fuselage 1 is connected to the base 2 by a screw, and the shock-absorbing seat 3 is sleeved on the outside of the base 2. The shock-absorbing seat 3 is sleeved on the front end of the base 2 for easy and quick disassembly.

[0029] It is worth mentioning that the support legs 21 welded on the outside of the base 2 support the fuselage 1 when the fuselage 1 descends, and four groups of support legs 21 are provided, so that take-off and bolting are more stable.

[0030] Working principle:

[0031] First, the staff lifts the fuselage 1 into the air. When shooting is required, the rotating shaft 10 rotates inside the shock-absorbing seat 3, and the rotating seat 11 at the bottom is rotated out from the inside of the shock-absorbing seat 3, and extends outward through the rotating ring 14 outside the fixed rod 13. The sliding seat 15 slides upward on the outside of the extension rod 22 at the center position inside the rotating ring 14. At this time, the extension rod 16 drives the rotating arm 17 sleeved on the outside to rise. When long-term high-altitude shooting is required, the camera 20 at the front end of the rotating arm 17 is perpendicular to the ground. At this time, the rotating rod 19 inside the square groove of the fixed seat 18 is perpendicular to the ground under the action of gravity. At this time, the rotating rod 19 is pressed against the ground to prevent accidental falling in the air;

[0032] When the fuselage 1 falls to the ground quickly and unexpectedly, the anti-collision plate 6 at the front end of the base 2 is pressed against the ground. At this time, the anti-collision plate 6 is pressed against the telescopic rod 7 at the front end of the shock-absorbing seat 3. The telescopic rod 7 cooperates with the spring 8 to push the slider 4 to slide into the slide groove inside the shock-absorbing seat 3, and the impact force is reduced during the sliding process. Finally, the upper pressing plate 5 on the outside of the shock-absorbing seat 3 limits the movement of the slider 4 inside the slide groove of the anti-collision plate 6, protecting the camera module 12 from contacting the ground, and the impact force is reduced to a minimum.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
