UAV wing synchronous folding and unfolding mechanism

Abstract

The invention relates to UAV wings, and in particular to a UAV wing folding and unfolding mechanism. A synchronous folding and unfolding mechanism for UAV wings. The technical solution is as follows: before launch, the UAV wings are restrained by the launch tube in a folded state, and the frame, wing A and wing B are stacked together in parallel up and down. , the deployment drive spring is twisted, and the locking drive spring is compressed; when the drone is launched from the tube, the wings A and B expand to the left and right sides around the annular boss under the action of the deployment drive spring, and the tenons are locked at the same time. A. Tenon B maintains synchronization under the constraints of the unfolding synchronization piece and the limit strip; when wing A and wing B unfold to the set position, the locking drive spring drives the lower wing to move upward, and the lower wing boss It engages with the upper wing notch, and the upper wing boss engages with the lower wing notch to achieve locking in the rotation direction. The invention can ensure that the wings are in the same plane after deployment and avoid asymmetry in aerodynamic shape.

Description

technical field [0001] The invention relates to a drone wing, in particular to a folding and unfolding mechanism for a drone wing. Background technique [0002] UAV is a high-efficiency, low-risk high-tech weaponry in modern warfare. In order to improve the regional adaptability and maneuverability of UAVs on the battlefield, shorten the response time of weapon systems, and improve the reliability of weapon systems, a cylindrical launch form integrating packaging, storage, transportation, and launch is often adopted. [0003] The barrel-type launch UAV uses the wing folding method to put the UAV with a foldable expansion mechanism into the launch tube of the corresponding caliber. Accelerate to a safe takeoff speed in the launch tube of the length. [0004] For small unmanned aerial vehicles, elastic elements are often used as energy storage elements for wing expansion. For the expansion of wings with large aspect ratios, on the one hand, it is required to have enough ener...

AI Technical Summary

Problems solved by technology

At present, the widely used wing expansion mechanism either lacks the deployment synchronization mechanism, or the synchronization mechanism adopted is too complicated, which is not conducive to the application of the deployment mechanism on small UAVs.
