An unmanned aircraft, abbreviated as "drone", and abbreviated in english as "UAV", is an unmanned aircraft that is operated by a radio remote control device and a self-contained program control device, or is operated autonomously, either completely or intermittently, by an onboard computer. Compared with manned aircraft, unmanned aerial vehicles tend to be more flexible. The unmanned aerial vehicle is suitable for the fields of teaching, aerial photography, agriculture, plant protection, miniature self-timer, express transportation, disaster relief, wild animal observation, infectious disease monitoring, surveying and mapping, news reporting, electric power inspection, disaster relief, film and television shooting, romantic manufacturing and the like, and the application of the unmanned aerial vehicle is greatly expanded. To professional aerial photography aircraft, the price is higher, and the shooting equipment price that general unmanned aerial vehicle carried is comparatively expensive, and inside accurate electronic component is more, and the violent vibrations that the operation carelessly arouse can damage the structure of shooting equipment and unmanned aerial vehicle itself when descending. The supporting legs of most shock absorbing frames on the market have large edges and corners. In actual work, the landing of the unmanned aerial vehicle is mostly uneven cement ground and gravel ground. If unmanned aerial vehicle has the horizontally initial velocity when descending, the edges and corners of stabilizer blade can block and cause the unsmooth department on ground to turn on one's side very big possibility. But the unmanned aerial vehicle foot rest at present only plays the absorbing function mostly, and this just needs the plane hand to control unmanned aerial vehicle's horizontal velocity when descending. In case some accidents that lead to the too fast horizontal velocity of unmanned aerial vehicle when descending take place, will unmanned aerial vehicle turn on one's side, then destroy the paddle light, then heavy is out of control and flies in disorder.

As shown in fig. 1 and 2, the utility model provides an unmanned aerial vehicle shock-absorption side-turning-prevention foot rest, which comprises a foot rest body 1, wherein a foot rest mounting plate 2 is arranged at the first end of the foot rest body 1, and the upper part of the foot rest mounting plate 2 is connected with an unmanned aerial vehicle base; and a damping structure is arranged between the foot rest mounting plate 2 and the first end of the foot rest body 1. The second end of the foot rest body 1 is provided with a rolling mechanism, and the foot rest body 1 can roll on the ground through the rolling mechanism; the tail end 3 of the second end part of the foot rest body 1 adopts an upward tilting structure, so that the contact with the ground is avoided.

In the above embodiment, the foot rest body 1 has an approximately S-shaped structure, the first end and the second end of the foot rest body are both smooth curved bodies, and the radian of the end portion of the second end is greater than that of the end portion of the first end, so that the tail end 3 of the end portion of the second end tilts upwards.

In the above embodiment, the side plates 4 are symmetrically arranged on both sides of the lower part of the foot stool mounting plate 2. One end of each side plate 4 is connected with the middle part of the foot rest mounting plate 2, and the other end of each side plate 4 is connected with the first end of the foot rest body 1.

Wherein, all be provided with first pinhole 5 at the other end tip of every curb plate 4, every curb plate 4 is connected with foot rest body 1 through first round pin axle through this first pinhole 5, and first pinhole 5 and first round pin axle are clearance fit for foot rest mounting panel 2 and foot rest body 1 can rotate around first round pin axle.

In the above embodiment, the two ends of the lower part of the foot stool mounting plate 2 are respectively provided with the left and right countersunk seats 6 and 7; the upper part of the first end of the foot rest body 1 is also correspondingly provided with a left countersunk head seat 6 and a right countersunk head seat 7. And a second pin hole 8 is formed in each right countersunk seat 7, and a second pin shaft is arranged in each second pin hole 8. The shock absorption structure is arranged between the foot rest mounting plate 2 and the foot rest body 1 through a left counter sink seat 6, a right counter sink seat 7 and a second pin shaft.

In the above embodiment, the shock-absorbing structure includes the compression spring 9 and the extension spring 10. Two ends of a pressure-bearing spring 9 are respectively embedded in the foot rest mounting plate 2 and the left countersunk seat 6 of the foot rest body 1, and two ends of a tension spring 10 are respectively hung on a second pin shaft in the foot rest mounting plate 2 and the right countersunk seat 7 of the foot rest body 1.

In the above embodiment, two through holes are provided at the top of the foot stool mounting plate 2, and the bolt is used to mount the foot stool mounting plate 2 on the unmanned aerial vehicle base through the through holes.

In the above embodiment, the second end of the foot rest body 1 is provided with more than one ball groove for accommodating and installing the rolling mechanism.

When unmanned aerial vehicle has great horizontal initial velocity to strike subaerial when descending, pressure-bearing spring 9 and extension spring 10 warp, cushion the impact force, and ball 11 can be subaerial rolling, has bigger buffer distance. And because the terminal 3 of second end tip of foot rest body 1 is the perk portion, the terminal 3 of second end tip of foot rest body 1 can not block because of the unevenness of ground, because the foot rest can anticlockwise rotation an angle when resisting the buffering again, the angle of terminal perk can be bigger, further prevents that the terminal ground of blocking. Unmanned aerial vehicle before the complete stop rotation, the attitude control who flies the accuse can not stop, that is to say, when the foot rest rotates after contacting ground, flies the accuse and still is controlling unmanned aerial vehicle's gesture, like this, the whole slope of unmanned aerial vehicle that the big one side of foot rest rotation amplitude arouses also can slowly turn back horizontal position in the attitude control who flies the accuse, makes unmanned aerial vehicle overall stability get off.

The above embodiments are only for illustrating the present invention, and the structure, size, arrangement position and shape of each component can be changed, and on the basis of the technical scheme of the present invention, the improvement and equivalent transformation of the individual components according to the principle of the present invention should not be excluded from the protection scope of the present invention.
