A multi-mode drive device for flapping and retracting wings of a miniature flapping wing aircraft

Abstract

The invention relates to a wing flapping and unfolding and folding multi-mode driving device of a micro flapping wing air vehicle. The wing flapping and unfolding and folding multi-mode driving deviceof the micro flapping wing air vehicle is mainly composed of a motor, a machine frame, pawl fixing disks, a rope-winding wheel, a bolt, an end cap, a gear, a hinge pin, pawls and a guide pin. Compared with the prior art, the wing flapping and unfolding and folding multi-mode driving device can control positive and negative rotation and starting and stopping of a single motor to realize the control over multiple actions of unfolding, flapping, folding and fixing of wings, the unfolding and folding function of the wings is increased, at the same time, the quantity of driving motors is not increased, more lifting force is saved for the micro flapping wing air vehicle, and more space is provided for the micro flapping wing air vehicle to carrying other micro-devices. The wing flapping and unfolding and folding multi-mode driving device solves the problem that the actions of flapping and unfolding and folding of the micro flapping wing air vehicle cannot be controlled at the same time, andthe multiple actions of the wings are unified to one device to realize switching and control, so that the functions of the micro flapping wing air vehicle are more various, and invisibility and portability are further enhanced.

Description

technical field [0001] The invention belongs to the field of micro-aircraft, and relates to a driving device for a micro-flapping-wing aircraft, in particular to a multi-mode driving device for flapping and retracting wings of a micro-wing-wing aircraft. Background technique [0002] Micro air vehicle is the collective name for the smallest type of aircraft. Since scientists proposed the concept of micro air vehicle in 1992, many researchers at home and abroad have carried out a series of researches in this field in view of its huge potential application value in military and civilian fields scientific research. Compared with conventional aircraft, MAV has outstanding advantages such as small size, easy to carry, flexible maneuvering, low noise, and good concealment. Micro air vehicles can be divided into fixed-wing, rotary-wing and flapping-wing types according to the flight mode. In terms of flexibility, concealment and noise control, the flapping-wing micro-aircraft has ...

Problems solved by technology

[0004] However, this flapping-wing micro-aircraft with the functions of flapping and retracting wings needs to be equipped with multiple drive sources, namely, the flapping drive motor and the retracting and retracting drive motor. The increase in the number of drive motors will increase the overall weight of the aircraft. , making the aircraft heavy, the lift required for its flight will also increase, which greatly reduces the flexibility and flight efficiency of the aircraft, and reduces the overall flight performance of the aircraft
