Self-adjustment deformation foldable wing mechanism for foldable flapping wing micro air vehicle

Abstract

The invention discloses a self-adjustment deformation foldable wing mechanism for a foldable flapping wing micro air vehicle, and belongs to the technical field of micro air vehicles. The self-adjustment deformation foldable wing mechanism mainly consists of three folding wings, three connecting rods, a locking pin, a polyvinyl chloride wing membrane, fixing frames, a locking pin and electric artificial muscle, wherein the two sides of the middle folding wing are connected with the left and right folding wings through the locking pins respectively; the three connecting rods are movably connected with the folding wings and a sliding block through the locking pins respectively; the polyvinyl chloride wing membrane is glued on the lower surfaces of the three folding wings; the two fixing frames are glued on the lower surface of the polyvinyl chloride wing membrane and are fixed on the folding wings by the locking pins. According to the self-adjustment deformation foldable wing mechanism disclosed by the invention, under the control of a single chip microcomputer, all components can make accurate response to effectively finish the actions of wing spreading and wing retraction. Throughthe electric artificial muscle, the self-adjustment deformation foldable wing is kept in a folded state, the working efficiency is high, and the recycling and the carrying are facilitated.

Description

technical field [0001] The invention belongs to the technical field of micro-aircraft, and in particular relates to a self-adjusting and deformable foldable wing mechanism for a foldable flapping-wing micro-aircraft. Background technique [0002] Because of its small size, light weight, and good concealment, micro-aircraft are more widely used in reconnaissance, search, etc. Among them, foldable flapping-wing micro-aircraft has better prospects for development and application in the future. [0003] In order to adapt to the natural environment, Coleoptera beetles fold their flexible hind wings under the elytra to facilitate crawling and concealment. When the micro-aircraft performs tasks such as low-altitude reconnaissance and complex terrain survey, it will encounter narrow passages or spaces, and the straight wings cannot fly through it. However, the foldable flapping-wing micro-aircraft can fold the wings, crawl through obstacles, complete exploration, etc. Work. Theref...
