Imaging lens driving module, camera module and electronic device

Abstract

An imaging lens driving module includes a lens assembly carrier, an imaging lens assembly, a first frame element, an adjustable aperture element, a circuit board, a flexible wire plate, a first driving element and a second driving element. The imaging lens assembly is disposed in the lens assembly carrier, and disposed against a first track of the first frame element via a first ball element. The adjustable aperture element is connected to the lens assembly carrier. The circuit board is disposed on an image side of the imaging lens assembly. The flexible wire plate is coupled to the circuit board and the lens assembly carrier. The first driving element is for driving a fixing portion of the adjustable aperture element to rotate relative to the rotating portion thereof so as to drive to blades for expanding or reducing an aperture hole. The second driving element is for driving the lens assembly carrier to move along a first direction. It is favorable for achieving the effect of auto-focuing by co-moving the flexible wire plate and the adjustable aperture element.
