1. A camera motor configured to drive a lens, wherein the camera motor comprises:
a motor housing comprising an accommodating cavity, wherein the accommodating cavity comprises an inner wall;
a lens bearing apparatus accommodated in the accommodating cavity and spaced apart from the inner wall, wherein the lens bearing apparatus comprises an outer surface, wherein the outer surface comprises an axial plane surface that is parallel to an optical axis direction of the lens and a circumferential axis plane surface that is perpendicular to the optical axis direction of the lens, and wherein the lens bearing apparatus is configured to:
bear the lens; and
drive the lens to move in the optical axis direction of the lens relative to the outer surface;
a drive apparatus accommodated in the accommodating cavity and configured to drive the lens bearing apparatus to move in the accommodating cavity; and
a cushioning part disposed on the outer surface and comprising:
a first cushioning part in contact with or separated from the inner wall and configured to move in the accommodating cavity along with the lens bearing apparatus; and
a second cushioning part coupling the outer surface and the inner wall and configured to deform when the lens bearing apparatus moves in the accommodating cavity,
wherein the first cushioning part and the second cushioning part are both disposed on a same one of the axial plane surface or the circumferential axis plane surface of the lens bearing apparatus.
