Problems solved by technology

Although the mechanism has only one stage of transmission and is self-locking, the efficiency of the worm gear transmission is too low, which will inevitably consume a lot of energy, thereby greatly increasing the weight of the battery, which is not conducive to the miniaturization of the flapping wing aircraft

Abstract

The invention relates to a micro flapping wing air vehicle. The micro flapping wing air vehicle mainly comprises a machine frame, a left flapping wing system and a right flapping wing system. A pinion (17) and a gear (16) are meshed to form first-stage transmission; and a small conical gear (28) is meshed with a large conical gear a (24), and a large conical gear b (35) respectively to form second-stage transmission, and drives a left driving rocker (19) and a right driving rocker (30) respectively through a connection rod a (23) and a connection rod b (34) so as to realize symmetrical flapping of the left and right flapping systems. The micro flapping wing air vehicle overcomes the defects that the volume is large due to the adoption of a pure cylindrical gear speed reduction mechanism, left and right flapping wings are asymmetric and transmission efficiency is too low due to the adoption of worms and worm gears in the prior art, and has the advantages of simple and compact structure, high efficiency, and symmetric left and right flapping, and meets the miniaturization development direction.

Description

technical field [0001] The invention relates to a flapping-wing aircraft, in particular to a miniature flapping-wing aircraft. Background technique [0002] The flapping-wing flight mode widely exists in the flight of flying creatures in nature. The flapping-wing flight includes the advantages of fixed-wing flight and rotary-wing flight. It can take off, accelerate and hover quickly, and has high maneuverability and flexibility. The flight modes of flying creatures can be roughly divided into three categories: low-frequency flapping flight, such as many large birds (hawks, vultures, wild geese, seagulls, swans, etc.), with longer and larger wingspan and low flapping frequency, It ranges from zero to tens of hertz, using low-frequency flapping and gliding in the form of flapping; intermediate-frequency flapping flight, mainly for medium-sized birds (such as swallows, sparrows, pigeons, etc.) Large, the flapping frequency is relatively high, and gliding is rarely used; high-f...
