    摘要: There is disclosed a driving device for piezoelectric actuator, in which a voltage is applied to a piezoelectric actuator to generate a mechanical deformation therein, thus actuating a mechanical system. In an aspect, the piezoelectric actuator is at first given a voltage of inverse polarity, for generating a displacement in an opposite direction, and then given a voltage of forward polarity, for generating a displacement in the normal functioning direction, thereby actuating the mechanical system. Displacement and acceleration become larger, as the displacement of the actuator takes place from a position in the inverse direction.

    摘要: A lens module (100) including a base (110), a lens (120), a front cover (130), a first shielding plate set (140), a second shielding plate set (150), and a gasket (160) is provided. The lens is disposed on the base. The front cover is rotatably disposed above the base and the lens, and the front cover has a first through hole (131). Each of the first shielding plate set and the second shielding plate set is pivoted on the base. The second shielding plate set and the first shielding plate set interfere with each other. The gasket is fixed in the first through hole and coupled to the second shielding plate set. The gasket has a second through hole (162). When the base and the front cover rotate relative to each other, the gasket rotates with the front cover and drives the first shielding plate set and the second shielding plate set to limitedly swing.

    摘要: There is disclosed a driving device for piezoelectric actuator, in which a voltage is applied to a piezoelectric actuator to generate a mechanical deformation therein, thus actuating a mechanical system. In an aspect, the piezoelectric actuator is at first given a voltage of inverse polarity, for generating a displacement in an opposite direction, and then given a voltage of forward polarity, for generating a displacement in the normal functioning direction, thereby actuating the mechanical system. Displacement and acceleration become larger, as the displacement of the actuator takes place from a position in the inverse direction. In another aspect, the electrical insulation state of the piezoelectric actuator is detected, and, if deteriorated, the destruction of insulation is prevented by an alarm generation and/or inhibition of voltage application. In an embodiment, the insulation state is identified from the ambient humidity of the actuator. In another aspect, if the detected humidity is at a high level that may induce destruction of insulation, the piezoelectric actuator is driven with a low voltage, in order to dehumidity by heat generation. Also shutter control devices for camera, utilizing piezoelectric actuator, are disclosed.

Zur Bildung eines kompakten Antriebs werden erfindungsgemäß folgende Merkmale vorgeschlagen:

    a) Der Linearmotor (4) weist zumindest zwei miteinander fluchtende Permanentmagneten auf, deren sich in einem axialen Abstand gegenüberliegenden Polflächen eine gleichgerichtete Polung aufweisen und zwischen sich eine Weichmagnetscheibe gleicher Außenkontur einschließen;
    b) die Permanentmagnete (6) mit der zwischengeschalteten Weichmagnetscheibe (7) sind allseitig von einem Weicheisentopf umschlossen, dessen innere Mantelfläche mit der äußeren Mantelfläche der Permanentmagnete und der Weichmagnetscheibe einen ringförmigen Spalt begrenzt;
    c) in dem genannten Spalt ist axial verschiebbar der Spulenkörper gelagert, der zwischen zwei Anschlägen einen Arbeitshub auszuüben vermag und in jeder seiner beiden Endstellungen mit seiner Wicklung die Weichmagnetscheibe (7) übergreift;
    d) zur Übertragung der Axialverschiebung des Spulenkörpers auf den zugeordneten Verschlußvorhang ist an dem Spulenkörper ein Antriebselement vorgesehen, das durch eine angepaßte, im Weicheisentopf vorgesehene Öffnung nach außen ragt.
