specific Embodiment approach 1

[0019] Specific implementation mode 1. Combination Figure 1 to Figure 4 Describe this embodiment, an unfolding and locking mechanism, which is applied to the unfolding and locking mechanism of the folding wings of the barrel-type launching aircraft. When the aircraft is launched from the barrel, the folding wings can be quickly unfolded and locked under the interference of aerodynamic resistance. With horizontal folding, two movements of rotation and translation occur during the unfolding process. Specifically, it includes an airfoil 1, a locking device 2, a guide bracket 3, a torsion spring 4, a guide rod 5 and a wing shaft 7. The guide bracket 3 is connected to the aircraft by screws, and the guide bracket 3 is provided with a shaft hole 3-1 and a guide groove 3-2. The airfoil 1 is connected to the wing shaft 7 through the pin 6 and the connecting sleeve 8, the wing shaft 7 drives the airfoil 1 to move through the pin 6 and the connecting sleeve 8, and the wing shaft 7 sli...

Abstract

The invention discloses an unfolding and locking mechanism, relating to the field of folding wing mechanisms and solving the problems that the existing folding wing mechanism cannot realize horizontal folding, lacks a small-size folding wing unfolding and locking mechanism and is complicated in structure and large in mass. The unfolding and locking mechanism comprises a folding wing unfolding motion mechanism and a locking device, the folding wing mechanism adopts horizontal folding and does rotation and translation motions during an unfolding process, the unfolding relies on a torsion spring as a power source, the torsion spring can provide both torque and elastic force, and the rotation and linear motion of the wing can be realized within a small space range to complete the unfolding process of the wing. A locking device adopts a spring to drive a locking pin to lock, and the locking pin limits the motion of the wing in one direction so as to realize the locking of the wing without the influence on the unfolding of the wing. The unfolding and locking mechanism is simple in structure, reliable to unfold and lock, low in cost and compact in occupation space. When an aircraft is launched after leaving away a canister, the rapid unfolding and locking of the folding wing can be realized under the interference of pneumatic resistance.

Description

technical field [0001] The invention relates to the field of unfolding and locking mechanisms of folding wings, in particular to an unfolding and locking mechanism used in the field of barrel-launched small aircraft. Background technique [0002] Folding-wing aircraft is of great significance to the transportation, storage, adaptability of the aircraft, and the reduction of the size of the packing box. Therefore, the folding-wing aircraft has received more and more attention. The unfolding performance of the folding wing mechanism directly affects the flight performance of the aircraft, so it is of great significance to invent a fast unfolding locking mechanism. [0003] The traditional driving methods of folding wing mechanism include gas cylinder type, motor drive, hydraulic drive and spring drive. It is difficult to realize the above-mentioned transmission mode for the small horizontal folding wing mechanism, and there is no case of realizing lateral folding on a small a...
