Title:
PIEZOELECTRIC DRIVE STRUCTURE AND IMAGING MODULE
Document Type and Number:
WIPO Patent Application WO/2021/135135
Kind Code:
A1
Abstract:
Disclosed are a piezoelectric drive structure and an imaging module, the piezoelectric drive structure comprising: a support layer; a piezoelectric element, adhesively bonded to the upper surface of the support layer; the piezoelectric element is separated into a plurality of sub-piezoelectric elements by an electrical isolation structure in the length direction, each sub-piezoelectric element being equipped with an independent electrode lead-out terminal, individually energizing each sub-piezoelectric element, the sub-piezoelectric element expanding and contracting, pulling the support layer to generate deformation; energizing each sub-piezoelectric element, such that the piezoelectric element can drive the support layer to produce a variety of warping changes. The imaging module comprises: a piezoelectric drive structure, comprising a movable end and a fixed end; a support block, used for supporting and fixing the fixed end; moved elements connected to the movable end, the moved elements comprising a lens group, an imaging sensor element, an aperture, a mirror, or a lens sheet; an external signal connection terminal, electrically connected to the piezoelectric drive structure; in the energized state, the movable end moves up or down with respect to the fixed end, moving the moved elements.
