Asymmetric shape memory alloy actuator for preventing accidental actuation
A recently granted patent (Publication Number: US11946461B2) discloses an asymmetric inertial bistable shape memory alloy actuator. The actuator comprises a stationary support, a movable slider, and a crank-and-rod mechanism with inertial elements. A shape memory alloy wire is used to switch the mechanism between stable positions, with biasing means to return it to the initial position. The patent specifies the distances and ratios between various components to ensure proper functionality and stability of the actuator.
Furthermore, the patent details additional features such as the inclusion of biasing springs, rotating levers, and magnets to enhance the actuator's performance. The orientation of weight forces and inertial elements is also specified to optimize the actuator's operation. By outlining these specific configurations and relationships between components, the patent aims to protect the unique design of this asymmetric inertial bistable shape memory alloy actuator, highlighting its potential applications in various fields requiring precise and reliable actuation mechanisms.
