Imaging lens module and electronic device

An imaging lens module with auto focus function, comprising:

• an imaging lens assembly, having an optical axis, and the imaging lens assembly comprising:
• an optical shielding plate, having an object-side surface, an image-side surface and a bore surface, and the bore surface being connected to the object-side surface and the image-side surface;
• and
• at least three lens elements, wherein one of the at least three lens elements is a most-object-side lens element, and the optical shielding plate is disposed on an object side of the most-object-side lens element;
• an electromagnetic driving component assembly, configured to drive the imaging lens assembly to move in a direction parallel to the optical axis, and the electromagnetic driving component assembly comprising:
• a first driving component, being electrically conductive and configured for an electric current to flow through;
• and
• a second driving component, providing a permanent magnetic field toward the first driving component;
• wherein the electromagnetic driving component assembly drives the imaging lens assembly to move in the direction parallel to the optical axis by a Lorentz force generated by an electromagnetic interaction between the first driving component and the second driving component;
• and
• a lens carrier, for the imaging lens assembly to be mounted thereto such that the imaging lens assembly can be wholly driven to move in the direction parallel to the optical axis by the Lorentz force, and the lens carrier comprising:
• an object-side part, located at an object-side end of the lens carrier, and the object-side part comprising:
• a tip-end minimal aperture, configured for light to travel through in the imaging lens assembly;
• and
• a first annular mounting surface, facing toward an image side, the first annular mounting surface being for the optical shielding plate to be mounted thereon, and the first annular mounting surface being in physical contact with the object-side surface of the optical shielding plate;
• and
• a mounting structure, configured for one of the first driving component and the second driving component to be mounted thereto;
• wherein the object-side part of the lens carrier further comprises a tapered surface, the tapered surface surrounds the tip-end minimal aperture, an area surrounded by the tapered surface tapers off from the image side to an object side, and the tapered surface extends to the first annular mounting surface;
• and
• wherein an axial distance on the optical axis between the tip-end minimal aperture and the first annular mounting surface is h, and the following condition is satisfied:
• 0.15 [mm]≤h≤1.3 [mm].
