Electromagnetic drive insect-like flapping-wing micro air vehicle

Abstract

The invention provides an electromagnetic drive insect-like flapping-wing micro air vehicle. Two wings are respectively connected with two ends of a carapace through flexible hinges; the wings, the carapace and a baffle block form a 'baffle' structure; the carapace is rigidly connected to a chest; a cylindrical permanent magnet is attached to the center position at the lower part of the chest; a spiral coil is attached to the center position at the upper part of a machine body opposite to the permanent magnet; the spiral coil and the permanent magnet are respectively located at the upper side and the lower side of each wing when being assembled; and the spiral coil overlaps with the axis of the permanent magnet. By adopting the traditional four-connecting rod drive mechanism, the transmission efficiency of the air vehicle is greatly improved; better flight stability can be obtained by adjusting the center of gravity to overlap with a lift center; by adopting simple structures of the flexible hinges and the baffle block, a certain degree of passive reverse can be obtained in a flapping process due to interaction of inertia force and aerodynamic force; the assembly precision is improved by folding and assembling; and miniaturization of the air vehicle is easily achieved.

Description

technical field [0001] The invention relates to a device in the technical field of micro-aircraft, in particular to an electromagnetic-driven insect-like flapping-wing micro-aircraft. Background technique [0002] The flapping-wing micro-aircraft is a micro-aircraft that imitates the flight of birds or insects. Bird-imitation and insect-imitation are two research models of flapping-wing micro-aircraft. The bird-imitation aircraft is larger in size and has a small wing vibration frequency; the insect-imitation aircraft is smaller in size and high in vibration frequency. [0003] At present, micro air vehicles can be divided into three categories according to the flight mode: fixed wing, rotary wing and flapping wing. Fixed-wing micro-aircraft and rotary-wing micro-aircraft are the products of the miniaturization of fixed-wing aircraft and rotary-wing aircraft, each has its own advantages, but their shortcomings of high energy consumption, low maneuverability, low flexibility...

AI Technical Summary

Problems solved by technology

[0005] At present, some related designs of insect-like flapping wing aircraft have been proposed in China, but the general size is relatively large and requires a more complicated transmission mechanism. Traditional machining methods are usually used, and it is difficult to achieve small size levels.
