Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "mounted on" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. When an element is referred to as being "secured to" another element, it can be directly secured to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present embodiment provides an unmanned aerial vehicle, which includes: a wing assembly 3, a chassis 4 and a bracket. The chassis 4 is used to assemble the wing assembly 3, and the wing assembly 3 can be an eight-axis wing.

Referring to fig. 2 to 4, the present embodiment further provides a retractable crash-proof support for an unmanned aerial vehicle, which can be applied to an unmanned aerial vehicle with high bearing requirements in the fields of agriculture, atmospheric monitoring, and the like. The support includes: a base plate 1 and at least two support assemblies 2.

The upper surface of the base plate 1 is fixedly provided with a chassis 4 for assembling a wing component 3 of the unmanned aerial vehicle.

The substrate 1 includes a mounting plate 11 and a plurality of movable plates 12 corresponding to the number of the supporting members 2. Each movable plate 12 is detachably connected to the base plate 1, and the bottom of each movable plate is used for mounting the corresponding support assembly 2.

In this embodiment, the mounting plate 11 may be provided with a plurality of mounting grooves 111 respectively corresponding to the plurality of movable plates 12. Each movable plate 12 can be slidably inserted into the corresponding mounting groove 111, and can be fixed to the mounting plate 11 by bolts. Through setting up the two detachable connection of fly leaf 12 and mounting panel 11, can be when fly leaf 12 is demolishd from mounting panel 11, accomodate as a whole together with corresponding supporting component 2 to what fly leaf 12's volume can set up is far less than mounting panel 11, thereby reduces to accomodate and occupies the volume, promotes the portability of unmanned aerial vehicle support.

The number of the support assemblies 2 can be two, and the two support assemblies 2 are arranged below the base plate 1 in an axisymmetric manner by taking the axis of the chassis 4 as a symmetric axis. Each support assembly 2 comprises a first support rod 21, a second support rod 22, a shock absorber 23 and a sleeve 24.

One end of the first support rod 21 is hinged with the lower surface of the base plate 1. The other end of the first support rod 21 and the second support rod 22 are perpendicular to each other, and therefore a T-shaped support leg structure is formed. In the T-shaped supporting leg structure, the bottom side of the second supporting rod 22 is a pressure side attached to the ground. In this embodiment, the second support rod 22 can be provided with a plurality of buffering ball joints 5 along self extending direction equidistance, and the buffering ball joints 5 can adopt light buffer materials with elastic deformation ability such as rubber, foam, need possess good wearability and corrosion resistance simultaneously, are applicable to more kinds of topography. Of course, in other embodiments, the outside of the second supporting rod 22 can be provided with a buffer sleeve matched with the length of the second supporting rod, as long as the whole safe load of the unmanned aerial vehicle is not affected.

In two supporting components 2, the contained angle size that the axis of two bracing pieces one 21 formed can be 60 ~ 120, and specific angle value can be according to unmanned aerial vehicle's focus, load and size adaptability setting. Thereby when unmanned aerial vehicle lands, the pressurized side in the T type landing leg structure contacts with ground, and buffering ball joint 5 can play preliminary cushioning effect, reduces the damage that causes T type landing leg structure itself with when striking.

The damper 23 is arranged at an included angle between the first support rod 21 and the substrate 1, and two ends of the damper 23 are hinged to the first support rod 21 and the substrate 1 respectively. The shock absorber 23 may adopt an existing damping spring shock absorber, and the shock absorber 23 has the dual advantages of a low frequency and a large damping of a steel spring shock absorber and eliminates a resonance amplitude phenomenon inherent to a steel spring.

Therefore, because a support rod 21 is hinged to the movable plate 12, when the T-shaped support leg structure lands and is impacted by the ground, the support rod 21 further rotates with the movable plate 12 along the inclination direction of the support rod, at the moment, the spring in the shock absorber 23 is impacted to deform, and meanwhile, the damping structure in the shock absorber 23 can absorb the energy generated by the vibration of the spring, so that the final amplitude of the spring gradually disappears, the whole support has a protection function of buffering and damping, and the unmanned aerial vehicle structure and the assembled parts thereof are prevented from being obviously damaged due to the impact of the ground. Of course, in other embodiments, the damper 23 may also be another type of damper, and the specific principle is similar to that of the wheel damper in the existing automobile, and will not be described herein again.

Referring to fig. 5, the sleeve 24 may be disposed at a vertical intersection of the first support bar 21 and the second support bar 22, and is used to fixedly mount the first support bar 21 and the second support bar 22. In this embodiment, the sleeve 24 may include two clamping plates 241 symmetrically disposed with respect to each other, and the two clamping plates 241 may also be fixed by bolts. The two clamping plates 241 jointly enclose a clamping groove 6 for fixing the end part of the first supporting rod 21 and a through hole 7 for the second supporting rod 22 to pass through.

The inner walls of the two clamping plates 241 at the through hole 7 can be respectively pasted with an anti-slip rubber layer, so that when the second supporting rod 22 is assembled by the sleeve 24, pretightening force and friction force can be exerted on the second supporting rod 22, and the second supporting rod 22 is prevented from sliding in the through hole 7. And the tip of bracing piece 21 can set to the fixture block form that matches with draw-in groove 6, and when assembling bracing piece 21 with sleeve 24 like this, draw-in groove 6 matches the joint with the fixture block, screws up the bolt of two grip blocks 241 again, realizes fixedly to can realize that each part in the T type landing leg structure is accomodate after dismantling, save occupation space.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
