1. A lens module comprising:
a lens;
an aperture assembly comprising:
a cover body sleeved outside the lens, the cover body comprising a top plate, and a first light hole defined on the top plate;
a driving member disposed on the cover body;
a rotating disk disposed on the top plate, a second light hole defined on the rotating disk; and
a plurality of blades disposed between the top plate and the rotating disk, the plurality of blades connected to the rotating disk, each of the plurality of blades comprising a side surface, and the side surfaces of the plurality of blades cooperatively defining a light-passing hole;
wherein the first light hole, the second light hole, the light-passing hole, and the lens are coaxial, the driving member is connected to the rotating disk and configured to drive the rotating disk to rotate, the rotating disk is configured to drive the plurality of blades to move closer to or away from each other, so as to adjust an aperture of the lens module;
the driving member comprises two piezoelectric blocks and a movable shaft disposed between the two piezoelectric blocks, the rotating disk is connected to the movable shaft; the two piezoelectric blocks are configured to drive the movable shaft to move, thereby driving the rotating disk to rotate; the driving member further comprises a transmission block disposed on the movable shaft, the transmission block is movably connected to the movable shaft and defines a gap, the driving member further comprises a transmission column disposed on a surface of the rotating disk facing the top plate, and the transmission column is clamped in the gap.
