Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As the embodiment of unmanned aerial vehicle and unmanned aerial vehicle frame, as shown in fig. 1 to fig. 6, unmanned aerial vehicle includes the frame, the frame includes two

horn

1, 1 middle part of horn is equipped with draw-in groove 11, and two 1 intercrossing of horn arrange to through the mutual joint of draw-in groove 11.

In this embodiment, a reinforcing and fixing plate 2 is disposed on a side surface of a crossing portion of the two booms 1, the reinforcing and fixing plate 2 includes a bottom plate 21 and two side plates 22, and the two side plates 22 are respectively fixedly connected with the side surfaces of the two booms 1, and may be fixed by screws. The reinforcing fixing plate 2 has the function of a reinforcing rib to reinforce the connection between the two arms 1. The number of the reinforcing fixing plates 2 is also multiple, and the reinforcing fixing plates are distributed at four intersections of the two machine arms 1.

In this embodiment, the depth of the slot 11 is half of the height of the horn 1, so that after the cross clamping, the upper surface of the horn is the same plane, which facilitates the installation of the machine body. The horn 1 includes inside pipe 12 and outside square pipe 13, and four lateral walls of inside pipe 12 and outside square pipe 13 all have tie point 14. The torsion resistance of the round pipe is strongest, the bending resistance of the square pipe is strong, four small nearly triangular structures are formed by the round pipe, the square pipe and the connecting point 14 in a surrounding mode, the structure is most stable, and the horn 1 adopts a mode that the inner round pipe 12 is combined with the outer square pipe 13, so that the bending resistance and the torsion resistance are perfectly expressed. The horn 1 of the composite construction is lighter in weight than a horn of a single design, which can be made by an extrusion process, at the same strength.

In this embodiment, two ends of the horn 1 are respectively provided with a support arm 3, a folding joint 4 is arranged between the support arm 3 and the horn 1 and can be folded downwards (or folded left and right), and the outer end of the support arm 3 is used for fixing the rotor. After folding unmanned aerial vehicle volume diminishes, is convenient for transition and transport.

The unmanned aerial vehicle frame includes two

horn

1, and 1 middle part of horn is equipped with draw-in

groove

11, and 1 intercrossing of two horn is arranged to through the mutual joint of draw-in groove 11, frame bulk strength and antitorque commentaries on classics ability no longer rely on the organism, but mainly rely on horn 1, and horn 1 generally adopts the alloy of light high strength to make, and intensity is guaranteed, and draw-in groove joint structure can guarantee that the crossing angle between two horn 1 does not change, prevents relative rotation, and stability is high, and antitorque commentaries on classics ability reinforce.

In this embodiment, the unmanned aerial vehicle further includes a body 5, the body 5 includes a bottom plate 51 and a side wall 52, and the bottom plate 51 is fixed on the horn 1. Unmanned aerial vehicle's organism 5 is installed in the frame, no longer bears the distortion power and the bending force of flight rotor, and what can do is thinner.

In this embodiment, unmanned aerial vehicle still includes foot rest 6, all be equipped with the screw hole on horn 1, bottom plate 51 and the foot rest 6, screw 7 passes the screw hole on horn 1, bottom plate 51 and the foot rest 6 simultaneously, fixes horn 1, bottom plate 51 and foot rest 6 as an organic whole. The body 5 and the foot rest 6 can increase the strength of the frame, play a role in supplementing the strength and further increase the torsion resistance and the falling resistance of the frame; one screw 7 can fix the horn 1, the bottom plate 51 and the foot rest 6 at the same time, and belongs to the design of lightest weight, so that the weight of the unmanned aerial vehicle is reduced to the maximum extent.
