Self-locking wing folding-unfolding mechanism for foldable flapping-wing micro air vehicle

Abstract

The invention discloses a self-locking wing folding-unfolding mechanism applied to a foldable flapping-wing micro air vehicle. The self-locking wing folding-unfolding mechanism comprises a spine back plate, an incomplete gear shaft, an O-shaped rack bracket, a shaft coupling, a micro motor, camshafts, cams, a machine body, deep groove ball bearings, bearing bases, a support plate, bolts, an elytron shell, a foldable wing and elastic overhead hooks. The self-locking wing folding-unfolding mechanism is arranged in the machine body. Under the control of a micro server motor, the mechanisms can make responses accurately and rapidly, and wing folding and unfolding actions are finished naturally. The flapping-wing micro air vehicle can rapidly finish the wing folding action quickly after landing, so that the working efficiency is increased; a stable self-locking structure can be formed between the wing and the machine body after the wing folding action is finished, so that the wing is prevented from sliding out of an enclosed space, and the working sustainability of the wing is ensured; meanwhile, the self-locking structure can be smoothly unlocked when the air vehicle takes off once again, so that the air vehicle can take off rapidly.

Description

technical field [0001] The invention refers to a self-locking wing retracting and spreading mechanism, in particular a self-locking wing retracting and spreading mechanism for a foldable flapping-wing micro-aircraft is designed. Background technique [0002] Flying at an ultra-low altitude like an insect and flexibly completing multiple detection and search tasks is the development direction of the current and future micro-aircraft. Among them, the multiple advantages of foldable-wing micro-aircraft make it have better application prospects in the future. [0003] However, in the current design and development process of foldable micro-aircraft, there are still many problems to be solved. For example, the flapping wing folding mechanism is slow to "retract the wings" after landing; ; and problems such as the discontinuity of the action of "spreading wings" again, these problems may affect the flight performance of the aircraft after it takes off again.

Problems solved by technology

[0003] However, in the current design and development process of foldable micro-aircraft, there are still many problems to be solved, such as the flapping wing folding mechanism's "wing-retracting" action after landing is relatively slow; the wing is easy to slide out after being put under the elytra-shaped shell ; and problems such as the discontinuous action of "spreading wings" again, these problems may affect the flight performance of the aircraft after it takes off again
