Missile tail folding mechanism and missile capable of releasing folding lock by using servo
The tail folding mechanism designed with the missile's own components is unlocked by the servo, allowing the tail to be folded and automatically deployed without external constraints. This solves the problems of tail folding restricting the carrier aircraft and unstable deployment in the existing technology, and improves the safety and reliability of the missile.

Abstract
The present invention discloses a missile tail folding mechanism and a missile that utilizes a servo to release the folding lock. The missile tail folding mechanism includes: an inner wing, disposed on a servo shaft; an outer wing, foldably disposed above the inner wing; an unfolding mechanism, disposed between the inner and outer wings, for driving the outer wing to rotate and unfold around the inner wing; an unfolding locking mechanism, disposed between the inner and outer wings, for locking the unfolded outer wing; and a folding locking mechanism, embedded within the outer wing. When the outer wing is folded, the folding locking mechanism maintains the folded and locked state. The present invention utilizes the tail servo as an unlocking actuator for the folding tail, eliminating the need for redundant equipment and enabling the tail servo to serve two functions. Furthermore, when the servo is not powered on, the servo shaft can provide a certain locking torque, improving the reliability of the folding lock.
