The invention relates to a shape memory alloy locking device, belongs to the field of mechanical locks, and solves the problems that a traditional shape memory alloy locking device is numerous and jumbled in structure and cannot be repeatedly used. The locking device comprises an upper shell and a lower shell, the upper shell and the lower shell are assembled together to define an internal working space, a friction plate is rotatably arranged in the working space, the locking device further comprises a limiting plate and a limiting plate control piece, the limiting plate is arranged between the friction plate and the upper shell, and the limiting plate control piece is arranged between the friction plate and the upper shell. The limiting plate control piece is made of shape memory alloy, the shape memory alloy stretches out and draws back to control the limiting plate to move up and down, and therefore the friction plate is unlocked and locked through the limiting plate. The locking device is simple and compact in structure and can be repeatedly used.

    本发明涉及一种形状记忆合金锁定装置,属于机械锁领域,解决了传统形状记忆合金锁定装置结构庞杂且无法反复使用的问题。该锁定装置包括上壳体和下壳体,所述上壳体与下壳体组装在一起限定出内部工作空间,摩擦片可转动地设置在工作空间内,所述锁定装置还包括限位板和限位板控制件,所述限位板设置在所述摩擦片与所述上壳体之间,所述限位板控制件的材质是形状记忆合金,所述形状记忆合金的伸缩控制限位板的上下移动,从而实现所述限位板对所述摩擦片的解锁与锁定。该锁定装置结构简单紧凑且可以反复使用。
