Patent ID: 11711031

Abstract:
A piezoelectric inertia actuator is disclosed herein, which includes an actuator body, a coupling body defining a receiver, a lock body positioned within the receiver, and a piezo body attached to the coupling body. At least one flexible frame configured to support an engaging body may extend from the piezo body. A spring blade configured to apply a preload force to the engaging body via a decoupling preload body may extend from the coupling body. A tension member may be positioned within the lock body and apply a preload force to the piezo body, thereby creating a net compressive stress therein. The piezoelectric inertia actuator may further include a piezo preload body configured to apply a reaction force to the piezo body in order to maintain the compressive stress therein. The preload applied to the piezo body may be substantially decoupled from the preload applied to the engaging body.
