Imaging module

An imaging module, comprising:

• a moved element, comprising a lens group, an imaging sensing element, or an aperture, a reflector, or a lens;
• a limiting groove, arranged on a surface of the moved element;
• a piezoelectric element, comprising a movable end and a fixed end, wherein the movable end is provided with a rotating shaft, the rotating shaft is arranged in the limiting groove, the limiting groove provides a mobile space for the rotating shaft, and the movable end drives the moved element to move upwards or downwards when the piezoelectric element in a power-on state;
• an elastic limiting piece, one end of which is connected to the movable end of the piezoelectric element and the other end is located in the limiting groove or connected to a portion opposite to an end face of the movable end, wherein the elastic limiting piece is in a free state when the piezoelectric element is in a free state, and the elastic limiting piece is compressed or stretched when the movable end of the piezoelectric element is warped;
• a supporting block, configured to support and fix the piezoelectric element, wherein the fixed end is fixed at the supporting block;
• and
• an external signal connection end, electrically connected to an electrode in the piezoelectric element.
