Embodiment Construction
[0033] Such as figure 1 As shown, the piezoelectric micro-motion platform amplified based on flexible hinges includes a frame 1 and a loading platform 16; a micro-drive 5 and an amplifying mechanism for amplifying the driving displacement of the micro-drive 5 are installed on the frame 1 .
[0034] Such as figure 2 As shown, the amplification mechanism is a double rocker mechanism installed on the frame 1; the active rocker 12 of the double rocker mechanism is provided with an extension section away from the end of the connecting rod 17, and the free end of the active rocker extension section 11 is against the micro drive. 5. The active rocker 12 and its extension 11 take the hinge point of the active rocker 12 and the frame 1 as the fulcrum to form an enlarged lever; the length of the extension of the active rocker 12 is less than the length of the active rocker 12 without the extension, so , the active rocker 12 utilizes the lever amplification effect to amplify the displa...
