Problems solved by technology

The invention provides a miniature semi-active folding flapping wing, including front beam, inclined beam, wing rib and skin, by dividing the single wing into two sections, using fixed folding seat, folding head, folding head rocker arm and soft steel rope to connect, In order to realize the asymmetric flapping up and down of the flapping wings, the invention only provides a slight folding in the flapping up and down of one wing, and cannot achieve complete folding under static conditions, nor does it involve flapping of different amplitudes and phases of two pairs of wings

Abstract

The invention relates to a bionic foldable double-wing flapping mechanism which specifically aims to achieve folding, unfolding and flapping of double wings by using a positive and negative rotation driving gear set of a single motor, in addition, flapping effects of front and rear wings at different vibration amplitudes and different phase positions are achieved, biological characteristics of twodouble wings of an insect can be simulated, and the aerodynamic performance of flying can be improved. The mechanism is mainly used for improving the complex environment adaptability of a micro ornithopter, and functions such as search and rescue, mapping, reconnaissance, near terrorist fighting and colonial attack and interference can be well achieved.

Description

technical field [0001] The invention belongs to the technical field of robots, and particularly relates to a bionic foldable double-wing flapping mechanism. Background technique [0002] Flapping is a way of flying for flying animals after billions of years of biological evolution. Nearly one million birds and insects have chosen to fly, indicating that flapping is the best way to fly. Studies have shown that the flapping-wing robot has the characteristics of high efficiency, flexibility and concealment compared with fixed-wing and rotary-wing robots, and the flapping-wing robot can be used for military reconnaissance, observation, electronic jamming, target tracking, nuclear, biological and chemical sampling, and even defense and offense. As well as civilian monitoring, search and rescue, surveying and mapping, surveys, etc., so the research on flapping aircraft has become a hot spot. [0003] The flapping mechanism can be mainly divided into the double-wing flapping mecha...
