Problems solved by technology

The above two transmission mechanisms have high transmission efficiency, but there are also obvious defects, that is, the above-mentioned mechanisms can only realize the flapping of the wings but not the twisting of the wings, so that they can only generate lift without thrust

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 Shown is a transmission mechanism of a miniature flapping wing aircraft, which is characterized in that it includes: a driving wheel 1, a driven wheel 2, a connecting rod 3, a twisting disc 4, and a chute 5; the driving wheel and the driven wheel are located on the same plane; The driving wheel meshes with the driven wheel;

[0014] A twist disc is arranged between the chute and the driving wheel, and the twist disc can perform twisting motion; one end of the connecting rod is connected with the twist disc, and the other end is connected with the driven wheel; the connecting rod drives the chute to reciprocate; the driving wheel An inclined thin rod is fixed on the top, and the thin rod can slide in the chute. The diameter of the thin rod is smaller than the diameter of the chute.

[0015] The present invention uses a micro motor as power; th...

Abstract

The invention discloses a micro flapping-wing air vehicle drive mechanism, which is characterized by comprising a driving wheel, a driven wheel, a connecting rod, a twist plate and a slide chute, wherein the driving wheel and the driven wheel are located on the same plane; the driving wheel is meshed with the driven wheel; the twist plate is arranged between the slide chute and the driving wheel and can carry out twist motion; one end of the connecting rod is connected with the twist plate and the other end of the connecting rod is connected with the driven wheel; the connecting rod drives the slide chute to move in a reciprocating manner; an inclined slender rod is fixed on the driving wheel and can slide in the slide chute. According to the micro flapping-wing air vehicle drive mechanism, flapping and twisting of wings can be achieved, so that an air vehicle theoretically generates lift force and thrust; and the structure is simple, light and handy.

Description

technical field [0001] The invention relates to the field of transmission devices of aircraft, in particular to a transmission mechanism of a miniature flapping-wing aircraft. Background technique [0002] Mini flapping flying chess (MAV) has unique advantages and has many applications in national defense and people's livelihood. And the transmission mechanism of fluttering flying chess is the key point in the research, and the common transmission mechanisms include piezoelectric transmission and mechanical transmission. And mechanical transmission is the main transmission mechanism of flapping wing flying chess because of its stability and precision. The current transmission mechanism mainly adopts a single-crank-rocker mechanism or a double-crank-rocker mechanism. The structure of the single-crank-rocker mechanism is simpler, but it is asymmetrical, and the structural length needs to be optimized. The structure of the double-crank-rocker mechanism is symmetrical and is m...
