Abstract:
1. A photographing module at least comprising a lens unit, an electrically controlled focusing mechanism, an elastic unit, a supporting base and a photosensitive device, wherein: said lens unit at least comprises one lens element; said electrically controlled focusing mechanism at least comprises a movable member and a fixed member, wherein said movable member has a hollow central portion near an optical axis and is secured to said lens unit; said fixed member is secured to said supporting base; and said movable member is electrically driven to move said lens unit disposed therewith along the optical axis; said elastic unit has outer peripheral areas, inner peripheral areas and a plurality of bridge regions, wherein said inner peripheral area defines a central opening; said outer peripheral area and said inner peripheral area define an accommodating space therebetween; said bridge regions are symmetrically disposed in said accommodating space; each of said bridge regions has one end connected to said outer peripheral area and the opposite end connected to said inner peripheral area; each of said bridge regions has a plurality of continuous radial segments which are connected together, with all of the radial segments pointing toward an outer side of the elastic unit to form a plurality of symmetrically distributed centers; said inner peripheral area is attached to said movable member of said electrically controlled focusing mechanism; and said outer peripheral area is attached to said fixed member of said electrically controlled focusing mechanism or with said supporting base; said supporting base has a hollow central portion near the optical axis and is disposed with said electrically controlled focusing mechanism; and said photosensitive device is disposed with said supporting base at the image side of said photographing module.
