Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Such as figure 1 As shown, a micro-flapping-wing aircraft with a single-degree-of-freedom foldable wing of the present invention includes a single-degree-of-freedom foldable wing, a gear transmission system and a motor drive module.

[0028] In this embodiment, the two folding wings (1) are installed on the crank rocker mechanism in the gear transmission system 2, and are fixed on the frame together with the motor drive module 3. Such as figure 2 As shown, the folding wing includes the folding wing connecting plate 1-1, the folding wing frame 1-2, the hinge hinge 1-3, the tape measure spring driver 1-4, the folding wing film 1-5 and the folding wing film fixing rod 1- 6; Th...

Abstract

The invention discloses a miniature flapping-wing aircraft with a single-degree-of-freedom foldable wing, comprising a single-degree-of-freedom foldable wing, a gear transmission system and a motor drive module; the motor drive module and the gear transmission system are installed on the frame of the aircraft, The shaft is connected; the foldable wing and the gear transmission system are connected by a crank rocker mechanism to realize the synchronous flapping movement of the two foldable wings. The folding wing designed based on the origami theory of the present invention makes the folding wing have a greater folding rate, and the folding wing can be folded to reduce the storage space when not working, and the folding wing only has a single degree of freedom, which can be achieved by a tape measure spring The automatic unfolding and locking of the folding wings is realized, so that the folding reliability is significantly improved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a miniature flapping-wing aircraft with single-degree-of-freedom foldable wings. Background technique [0002] A micro-aircraft generally refers to a wingspan within 15cm, a weight of no more than 100g, a flight speed of 10-20m / s, and a flight time of 20-60min; it should have real-time imaging, navigation and communication transmission capabilities, and can be used in military reconnaissance and tracking. Military fields such as shooting and obtaining enemy information, as well as civilian fields such as post-disaster rescue, exploration and detection, and aerial photography have huge application prospects. [0003] At present, there are many kinds of flapping-wing micro-aircraft: the University of California, Berkeley, has been studying a micro-mechanical flying insect MFI since 1998, and by imitating the blowfly, a micro-aircraft that can realize autonomous flight and complex ...
