Imaging lens assembly module, camera module and electronic device

A camera module, comprising:

• an imaging lens assembly module, comprising:
• a lens carrier having an optical axis, wherein at least one lens element of the imaging lens assembly module is disposed at the lens carrier, and the lens carrier comprises an assembling structure;
• a rotatable component, comprising:
• a blade set comprising a plurality of rotatable blades, wherein all of the rotatable blades surround the optical axis to form a through hole, and a dimension of the through hole is variable;
• a rotating element connected to the blade set, and the rotating element configured to drive the blade set to adjust the dimension of the through hole;
• and
• at least two bearing members disposed between the rotating element and the lens carrier for supporting the rotating element to rotate, and the at least two bearing members aligned to the optical axis for aligning to the rotating element and the lens carrier, wherein each of the bearing members comprises:
• three contacted points physically contacted with the rotating element or the lens carrier, and the contacted points comprising:
• an inner contacted point being one of the contacted points closest to the optical axis;
• an outer contacted point being one of the contacted points farthest away from the optical axis;
• an upper contacted point being one of two of the contacted points farthest away on a direction parallel to the optical axis;
• and
• a lower contacted point being the other one of the two of the contacted points farthest away on the direction parallel to the optical axis;
• an imaging surface located on an image side of the lens carrier;
• and
• a holder portion;
• and
• an electronic module comprising a circuit board and an image sensor, the circuit board electrically connected to the image sensor, and the image sensor corresponding to the imaging surface;
• wherein the blade set of the rotatable component and the rotating element are disposed on the assembling structure of the lens carrier, and both of the blade set and the rotating element rotate relatively to the assembling structure, so that the dimension of the through hole is variable;
• wherein a fixed distance between the lens carrier and the circuit board is kept via the holder portion;
• wherein one of the contacted points is simultaneously one of the inner contacted point and the outer contacted point and one of the upper contacted point and the lower contacted point.
