The invention relates to the technical field of spacecraft docking locking, and provides an electric control button type docking locking mechanism based on shape memory alloy, which can realize simple, controllable and efficient unlocking. According to the invention, the shape memory alloy is combined with the mechanical button-type butt-joint locking mechanism, so that the unlocking operation difficulty is emphatically considered while the large clamping force of the mechanism is ensured, and the constructed button-type butt-joint locking mechanism has the characteristic of electric control automatic unlocking while the large clamping force is ensured; the problem that a button type locker is high in unlocking operation difficulty in the spacecraft docking and locking process is solved.

    本发明涉及空间航天器对接锁定技术领域,提供了一种基于形状记忆合金的电控按钮型对接锁定机构,能够实现简单、可控和高效的解锁。本发明通过将形状记忆合金与机械式按钮型对接锁定机构相结合,在保证机构具有较大的夹紧力的同时重点考虑了解锁操作难度,使得所构建的按钮型对接锁定机构在保证有较大夹紧力的同时具有电控自动解锁的特点,解决了按钮型锁紧器在航天器对接锁定过程中解锁操作难度高的问题。
