1. An optical component driving mechanism, comprising:
a fixed portion;
a movable portion arranged with the fixed portion along an optical axis, wherein the movable portion is movable relative to the fixed portion;
a driving assembly for driving the movable portion to move relative to the fixed portion; and
a first weighting component fixedly connected to the fixed portion, wherein the driving assembly is disposed on the first weighting component;
wherein the driving assembly comprises:
a driving component;
a transmission component connected to the driving component; and
a second weighting component connected to the driving component, wherein a density of the second weighting component is greater than a density of the fixed portion;
wherein the driving component is positioned between the transmission component and the second weighting component, and the second weighting component is disposed in the first weighting component.
