| titleOfInvention | A kind of miniature multi-channel piezoelectricity steering engine |
| abstract | The invention discloses a kind of miniature multi-channel piezoelectricity steering engines, belong to piezoelectric actuator technical field, it induces flexible beam deflection to drive rudder face using piezoelectric bimorph, individually control can be realized to multichannel on the basis of miniaturization, lightness, and keep good position control performance.The present invention includes: rudder face, flexible beam, slide unit, electromagnetism push-pull mechanism and piezoelectric bimorph；Piezoelectric bimorph is under the action of precompression spring, hinge support provides initial induction moment of flexure to output shaft and flexible beam, electromagnetism push-pull mechanism drives slide unit movement and provides axial thrust to flexible beam later, flexible beam generates the plastic deformation of preset direction under induction moment of flexure and the effect of slide unit axial thrust, output shaft and rudder face is driven to generate deflection using end angle displacement and moment of flexure, and self-locking after realizing in place under electromagnetism push-pull mechanism acts on.It is characterized in that the flexible beam, when generating large deformation, piezoelectric bimorph sector-meeting generates pullback motion under the action of locating piece and disengages with output shaft. |
