Embodiment Construction

[0036] below, with Figure 1 The structure for implementing the locking mechanism and the folding airfoil related to the present invention is schematically described. The following schematic implementations are intended to make it easier for those skilled in the art to understand the present invention, rather than to limit the interpretation of the present invention. The present invention can be replaced and / or improved on the following embodiments without departing from its overall concept.

[0037] figure 1 It shows a structural schematic diagram of the first part 3 and the second part 1 locked in the unfolded position by the locking device. According to an embodiment of the present invention, the first component 3 is connected to the second component 1 through a pivot, so that the second component 1 can rotate around the pivot, and then the second component 1 can be in different positions relative to the first component 3 .

Abstract

The invention discloses a locking mechanism and a folding airfoil with the locking mechanism, belongs to the technical field of aircraft design, and aims to solve the problem that the existing locking structure occupies the layout space in the span direction. The locking mechanism includes a first part, a second part and a locking device, the locking device includes a retractable locking pin, a locking hole, a release mechanism and a trigger mechanism, when the second part is in the deployed position, the release mechanism is triggered and drives the locking The pin protrudes and enters the locking hole; wherein, the central axis of the locking pin, the locking hole and the central axis of the pivot are arranged in parallel. Compared with the prior art, the space occupied by the present invention is flexible in design, and can meet the requirement of arranging locking devices in a small span-wise space.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and in particular relates to the structural design of a foldable airfoil, in particular to a foldable airfoil and its locking mechanism in place. Background technique [0002] Folding wings can reduce the radial size of the aircraft, reduce the volume of storage or launching devices, facilitate transportation or launch, and increase the carrying capacity of transport vehicles or ships. The function of the folding wing unfolding locking mechanism is to make the wing surface fold before the aircraft is used, and automatically unfold and reliably lock under the action of the driving force after launch or according to the needs during flight. [0003] The shape maintenance of the existing folding airfoil mainly depends on the spring pushing the lock pin into the hole after being unfolded in place. When it is not in place, the lock pin needs to be constrained to within the folding interface t...
