Problems solved by technology

[0004] As far as the current UAV wing design is concerned, the wing design with fixed wing length is generally adopted. On this basis, with the rotating shaft mechanism, the wing can realize a small range of rotation, and then slightly change the UAV wing length; or use "Switch knife" design, after the drone is launched, the wings are unfolded, but the drone's wing length cannot be further adjusted as needed during the subsequent flight of the drone

Embodiment Construction

[0026] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0027] The whole set of adjustable wings is fixed on the drone body through the rotating shaft III, and each mechanism and parts can move according to the predetermined design. The relative positions of each institution are as follows:

[0028] The whole set of adjustable wings is composed of a left wing A and a right wing B, each wing includes an inner wing I and an outer wing II, and the wings on both sides are arranged symmetrically.

[0029] When the wing is in the contracted state, the screw nut 16 is located on the ball screw 8 closest to the steering gear 6, at this time, the inner wing I is nested inside the outer wing II, and the spar 14 of the outer wing is nested in the Inner wing spar 4 interior.

[0030] When the wing is in the unfolded state, the screw nut 16 moves along the ball screw 8 in a direction away from the steering ge...

Abstract

The invention discloses a telescopic wing mechanism suitable for a small unmanned aerial vehicle. The telescopic wing mechanism is formed by nesting an inner wing and an outer wing, and the length of the wings is adjusted in a manner that the inner wing is fixed relative to the fuselage of the unmanned aerial vehicle and the outer wing slides relative to the inner wing. When the telescopic wing works, the steering engine of the inner side wing drives the ball screw to move, so that the screw nut moves along the preset guide rail, the moving process of the outer side wing relative to the inner side wing is completed, and the length of the wing is adjusted. A ball screw transmission mode is adopted, and the problem that the wing length of the unmanned aerial vehicle cannot be adjusted according to flight requirements when the unmanned aerial vehicle flies is solved.

Description

technical field [0001] The invention belongs to the field of drone wing design, in particular to a retractable wing structure suitable for drones. Background technique [0002] UAV combat is an important part of future unmanned combat. With the further development of the battlefield environment, the combat tasks of UAV will become more and more complex. Therefore, UAVs need to mount more equipment components and expand the functions of their existing mechanisms to meet actual needs. [0003] In order to adapt the drone to various flight conditions, adjusting the wing length of the drone is an important way. The short wing length can save the space required for take-off and landing and improve its concealment, while the long wing length can improve the drone’s The combination of the two can effectively improve the adaptability and comprehensive performance of UAVs to complex environments. [0004] As far as the current UAV wing design is concerned, the wing design with fixe...
