The invention discloses a locking and releasing mechanism, a wing and an unmanned aerial vehicle, and belongs to the field of locking mechanisms. The mechanism comprises at least one set of locking and releasing structure. The locking and releasing structure comprises a fixing shell, a clamping pin assembly, a shape memory alloy wire, a reset elastic piece and a fixing base. The fixed shell is fixed with a to-be-locked structure, and a through hole is formed in the surface close to the to-be-locked structure; the bayonet lock assembly is arranged in an inner cavity of the fixing shell, and when a lock hole formed in the structure to be locked is aligned with the through hole, the front end of the bayonet lock assembly can stretch out of the through hole and be clamped into the lock hole under the action of the elastic force released by the bayonet lock assembly; a bottom plate of the fixing seat is arranged at one end, deviating from the to-be-locked structure, of the fixing shell and the surface is parallel to the end face of the fixing shell; one end of the shape memory alloy wire is connected with the bayonet lock assembly, and the other end penetrates through the bottom plate and is connected with the heating providing mechanism; the shape memory alloy wire is sleeved with the reset elastic piece, and the two ends of the reset elastic piece abut against the clamping pin assembly and the bottom plate correspondingly. According to the invention, the wings can be freely switched at any time when being unfolded to any angle.

    本申请公开了一种锁紧释放机构、机翼和无人机,属于锁紧机构领域。机构包括至少一组锁紧释放结构;锁紧释放结构包括固定壳、卡销组件、形状记忆合金丝、复位弹性件和固定座;固定壳与待锁紧结构固定,靠近待锁紧结构的面上设置有通孔;卡销组件设置于固定壳的内腔,当待锁紧结构上设置的锁孔与通孔对齐时,卡销组件在自身释放的弹力作用下,其前端能够伸出通孔并卡入锁孔;固定座的底板设置于固定壳背离待锁紧结构的一端且表面与固定壳的端面平行;形状记忆合金丝的一端与卡销组件连接,另一端穿出底板与加热提供机构连接;复位弹性件套设于形状记忆合金丝,且两端分别抵于卡销组件和底板。本申请能够实现机翼展开至任意角度的随时随意切换。
