SHAPE MEMORY ALLOY-ACTUATED RELEASE MECHANISMS FOR DRIVE SYSTEMS

摘要

Embodiments of the invention relate to shape memory alloy ("SMA")-actuated release mechanisms for drive systems. In one embodiment, a SMA-actuated release mechanism includes at least one anchor point and a pivot point. The SMA-actuated release mechanism also includes a latch member pivotally coupled to the pivot point and configured to engage a drive member of a drive system. The SMA-actuated release mechanism further includes a SMA element having a first portion coupled to the at least one anchor point and a second portion coupled to the latch member. Activation of the SMA element causes the latch member to pivot about the pivot point, such that the latch member disengages from the drive member.
