Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0031] The present invention is a kind of miniature bionic flapping-wing aircraft based on single crank double rocker mechanism, such as figure 1 As shown, it includes a drive mechanism 14, a single crank double rocker mechanism 15, a flapping wing mechanism 16 and an attitude control mechanism 17. The aircraft generates driving force through the drive mechanism 14, and transmits the single crank double rocker mechanism 15, so that it drives the flapping wing mechanism 16 to flutter, and simultaneously adjusts the posture of the flapping wing mechanism 16 by adjusting the attitude control mechanism 17, Realize the attitude control of the aircraft.

[0032] The drive mechanism 14, such as figure 2 As shown, it is composed of a brushless motor 1, a transmission gear 10 and a motor gear 11. The brushless motor 1 is installed above the center line of symmetry o...

Abstract

The invention discloses a miniature bionic flapping aircraft based on a single-crank and double-rocker mechanism, and belongs to the technical fields of machine design and aircrafts. The aircraft adopts a single-crank and double-rocker mechanism, wherein the single-crank and double-rocker mechanism comprises a single-crank mechanism gear, a left wing rocker, a right wing rocker, a left wing connecting rod and a right wing connecting rod; the single-crank mechanism gear is fixed on a frame and forms a rotation pair; one end of each of the left wing connecting rod and the right wing connecting rod is connected with the single-crank mechanism gear through a pin; the other ends of the left wing connecting rod and the right wing connecting rod are respectively and rotationally connected with the left wing rocker and the right wing rocker, so as to transmit power; an extending section is formed at the second end point of each of the left wing rocker and the right wing rocker; the extending section is connected with a flapping wing structure, so as to drive the flapping wing to perform flapping. The aircraft can basically eliminate asymmetry of the aircraft during flight, has a function of switching various flight attitudes, and meanwhile has the characteristics of compact structure, high flexibility, high compactness and low weight.

Description

technical field [0001] The invention belongs to the field of mechanical design and aircraft technology, and in particular relates to a micro-bionic flapping-wing aircraft based on a single-crank and double-rocker mechanism. Background technique [0002] At present, micro-bionic flapping-wing aircraft has attracted widespread attention due to its small size, efficient flight mechanism, and broad application space. Aerodynamic research results show that for micro-aircraft with a main size of less than 15cm, the flying mode of the flapping wing has a larger lift-to-drag ratio, stronger anti-interference ability and more flexible maneuverability than the flying mode of fixed wings and rotors. Therefore, micro-flapping-wing aircraft will play a more important role in fields such as military affairs and detection, and will occupy a dominant position in the development of micro-aircraft. In the current research on micro-bionic flapping-wing aircraft, most of the wings of the mecha...
