A linear helical unfolding and folding wing mechanism

Abstract

The invention discloses a linear and spiral folding-wing unfolding mechanism, and relates to the field of a mechanism for converting linear motion generated by an actuation source into the rotational motion of a rotating shaft through the mechanism to unfold a folding wing. An outer wing is fixedly mounted at one end of an inner wing; a rotating device is fixedly mounted at the edge of the outer wing along the direction of the contact edge of the inner wing and the outer wing; an actuator is fixedly mounted at one end extending out of the outer wing, of the rotating device; the actuator and the rotating device are axially and fixedly mounted at the edge of the inner wing; the rotating device comprises a linear motion rod, a clamping pin, a sleeve and a spiral groove; the linear motion rod axially extends into the sleeve along the axis direction; the clamping pin is mounted at one end of the linear motion rod; the spiral groove is formed in the sleeve; the outer wall of the clamping pin is clamped in the spiral groove; the linear motion rod is driven by the actuator to make linear motion; and through the push of the linear motion rod, the clamping pin moves along the spiral groove towards the groove opening direction. Through the adoption of the linear and spiral folding-wing unfolding mechanism disclosed by the invention, locking of the folded state or the unfolded state of the folding wing is realized, and the problem that the automatic locking and unfolding time of a conventional folded wing unfolding mechanism cannot be accurately controlled is solved.

Description

technical field [0001] The invention relates to the field of a mechanism that converts the linear motion generated by an actuation source into the rotational motion of a rotating shaft through a mechanism to unfold a folded wing, in particular to a linear spiral unfolded folded wing mechanism. Background technique [0002] With the development of advanced technologies such as mobile launch vehicles, aircraft built-in weapon bays, and general-purpose vertical launch technology for ships, folding wings have become a key technology for the development of missile technology. [0003] In order to increase the range and maneuverability of missiles, most of them use large-area wing rudders, which increases the loading space of missiles and greatly limits the scope of application of missiles. In order to reduce the loading space, increase the ammunition capacity of the carrier, and improve the stealth capability of the missile-carrying aircraft, the foldable wing rudder is an effect...
