Embodiment Construction

[0026] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0027] combine Figure 1-Figure 7 , a non-complete gear control rotating foldable wing flying device of this embodiment, comprising a rotating foldable wing, a non-complete gear transmission mechanism, a gear mechanism and a rotating shaft 13;

[0028] The rotating foldable wing is fixedly connected to the rotating shaft 13. The rotating foldable wing includes a rotating frame 1 and a plurality of foldable hinges installed in the rotating frame 1. The gear mechanism connects the aircraft and the incomplete gear transmission mechanism. The incomplete gear transmission mechanism connects the hinge, and the gear mechanism and the incomplete gear transmission mechanism are used to control the unfolding and folding of the hinge.

[0029] The rotating frame 1 is provided with two rows of hinge arrays up and down, and the rotating frame 1 is provide...

Abstract

The invention discloses an incomplete gear control rotary foldable wing flight device which comprises a rotary shaft and a rotary foldable wing connected with the rotary shaft. The driving mechanism is used for driving the rotating shaft to rotate, so that the attack angle of the rotary foldable wing is adjusted, and the hinge is driven to be unfolded and folded; a gear mechanism and an incomplete gear transmission mechanism are symmetrically arranged on the rotating shaft in the radial direction; the gear mechanism is meshed with the incomplete gear transmission mechanism, and the gear mechanism can rotate relative to the axis of the rotating shaft and drives the incomplete gear transmission mechanism to rotate; each foldable wing comprises a rotating frame and a plurality of foldable hinges arranged in the rotating frame; the foldable hinge is connected with the push rod, and the push rod can move in the rotating frame in the axis direction of the rotating shaft. Rotation of the incomplete gear transmission mechanism can drive the push rod to move linearly, and therefore the hinge is driven to be unfolded and folded on the rotating frame. The pneumatic efficiency is improved.

Description

technical field [0001] The invention relates to the field of movable wing aircraft and flying robots, in particular to a non-complete gear control rotating foldable wing flying device for unmanned aerial vehicles. Background technique [0002] There are three flight types of aircraft: fixed wing, rotary wing and flapping wing, both of which are movable wings. [0003] Flapping wing flight is a flying method adopted by flying creatures in nature. It mainly uses the up and down flapping of the wings to generate lift and thrust at the same time. Flexibility, more suitable for performing flights around obstacles etc. For small-sized and low-speed aircraft flying under low Reynolds numbers, the unsteady lift generated by the flapping wing is much greater than the constant lift of the fixed wing; from the perspective of thrust, the propulsion efficiency of the flapping wing is higher than that of the propeller. At present, the research of flapping-wing aircraft mainly focuses on...
