a drone

Abstract

The invention discloses an unmanned aerial vehicle, comprising wings and tip small wings or pendant tails at two ends of the wings; the tip small swings or pendant tails can be quickly released and fitted manually without tools and can be automatically positioned and locked to the ends of the wings. By designing the releasable tip small wings or pendant tails, it is convenient to release the tip small wings or pendant tails while they are fastened, and tool-free quick manual release and fitting and automatic positioning and locking are achieved; the released tip small wings or pendant tails may be stacked and horizontally placed in a transport box, the height of the transport box for receiving the tip small wings or pendant tails extending in the height direction is reduced, and the size is reduced; the horizontally placed tip small wings and pedant tails are mutually released from the wings, there is no need to concern stress damage due to mutual staggering during transporting, transport weight is reduced, and portability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to an improved structure of an unmanned aerial vehicle, in particular to an unmanned aerial vehicle with vertical tails or winglets located at both ends of the wings for easy disassembly. Background technique [0002] A UAV is disclosed in Chinese patent 201320090583.2, which includes a wing integrated with the fuselage and a downward vertical tail (also called a winglet) at both ends of the wing. The lower part is provided with a parachute compartment for landing. When the UAV lands, the parachute is opened, and the UAV lands on its back. The parachute is used to slow down the speed of the UAV's free fall to avoid damage. The above-mentioned unmanned aerial vehicle has a compact structure and is easy to eject and take off. It can be widely used in surveying and mapping, aerial reconnaissance, surveillance, communication, anti-submarine, electronic jamming, etc. [0003] Of course, although the UAV has the advantages of small str...

Problems solved by technology

Therefore, it is necessary to design a special box to place the drone, especially to allow enough height to accommodate the vertical tail or winglets, resulting in the thickness of the box becoming very large, which is very inconvenient for train or air transportation, and during the consignment process It is also necessary to specially fix the vertical tail or winglet to avoid stress damage caused by misalignment of the vertical tail or winglet relative to the wing during the handling process, which will increase the weight of the structure and greatly reduce the portability of the UAV.
