The invention discloses a locking mechanism of a folding empennage and the folding empennage, and belongs to the field of empennages. A rotating structure of the locking mechanism is arranged on the upper wing surface, and two ends are fixed with the lower wing surface; the mounting shell is clamped in the lower wing surface; the first locking structure is arranged in the first cavity, and the second locking structure is arranged in the third cavity; the shape memory alloy wire is connected with the locking control structure and arranged in the second cavity, and when the shape memory alloy wire is in a cooling state, the front end of the locking control structure abuts against the lower end of the first locking structure, and the upper end of the first locking structure extends out of the mounting shell and clamps the rotating structure; when the shape memory alloy wire is heated, the shape memory alloy wire contracts to drive the locking control structure to move in the contraction direction, the first locking structure retreats into the first cavity, the rotating structure rotates to drive the upper wing face of the folding tail wing to rotate to be unfolded, meanwhile, the second locking structure is unlocked, and then the upper end of the second locking structure stretches out of the mounting shell and clamps the rotating structure. The locking control process is simple and ingenious.

    本申请公开了一种折叠尾翼的锁紧机构及折叠尾翼,属于尾翼领域。锁紧机构的旋转结构设置于上翼面,两端与下翼面固定;安装壳卡设于下翼面内;第一锁紧结构设置于第一腔体,第二锁紧结构设置于第三腔体;形状记忆合金丝与锁紧控制结构连接并设置于第二腔体,当形状记忆合金丝处于冷却状态时,锁紧控制结构的前端抵于第一锁紧结构的下端,并使第一锁紧结构的上端伸出安装壳并卡住旋转结构;当形状记忆合金丝被加热时,其收缩带动锁紧控制结构沿收缩方向移动,第一锁紧结构退回至第一腔体内,旋转结构旋转带动折叠尾翼的上翼面旋转至展开,同时第二锁紧结构解锁,之后其上端伸出安装壳并卡住旋转结构。本申请锁紧的控制过程简单、巧妙。
