Document Type and Number:
WIPO Patent Application WO/2021/253519
Kind Code:
A1
Abstract:
A lens module, comprising a housing (1), a lens (2), a focusing driving member (6), an anti-shake driving member (7), and a lens bracket (3), a first base (4), and a second base (5) which are sequentially arranged in a first direction (Z). Three first rolling balls (a) are arranged between the lens bracket (3) and the first base (4), and three second rolling balls (b) are arranged between the first base (4) and the second base (5); one of each first rolling ball (a) and each second rolling ball (b) can roll in an optical axis direction (X) and the other can roll in a second direction; the first direction (Z), the second direction (Y), and the optical axis direction (X) are perpendicular to each other; the lines connecting the centers of the three first rolling balls (a) form a non-isosceles triangle, and/or the lines connecting the centers of the three second rolling balls (b) form a non-isosceles triangle. The lens module can ensure that the area of motion of the center of gravity is in a triangle enclosed by lines connecting the three rolling balls.
