Camera module and electronic device

Abstract

A camera module (100, 200) comprising: a base (102, 202); a first rolling element assembly (141, 241) arranged on the base (102, 202) and comprising: at least three first rolling elements (1411, 2411), wherein a virtual circle (V) passes through the center point of each of the at least three first rolling elements (1411, 2411) and a first axis (X1) passes through the center point of the virtual circle (V); a first support (131, 231) connected to the base (102, 202) via the first rolling element assembly (141, 241), wherein the first rolling element assembly (141, 241) is arranged between the base (102, 202) and the first support (131, 231) and the first support (131, 231) 231) with the first axis (X1) as its center of rotation;a second rolling element arrangement (142, 242) arranged on the first support (131, 231) and comprising: at least two second rolling elements (1421, 2421), wherein a second axis (X2) passes through the center point of each of the at least two second rolling elements (1421, 2421) and the second axis (X2) is perpendicular to the first axis (X1); a second support (132, 232) connected to the first support (131, 231) via the second rolling element arrangement (142, 242), and the second support (132, 232) rotates relative to the first support (131, 231), the second axis (X2) serving as the center of rotation; a light path deflection element (120, 220) fixedly arranged on the second support (132, 232), wherein the The light path deflection element (120, 220) causes a light beam (L) to be deflected from the first axis (X1) to a third axis (X3), and the third axis (X3) is perpendicular to the second axis (X2);and a first drive, comprising: a first drive magnet (1512, 2512) fixedly arranged on the first support (131, 231); and a first drive coil (1511, 2511) fixedly arranged on the base (102, 202), wherein the first drive causes the first carrier (131, 231) to rotate, the first axis (X1) serving as the center of rotation; wherein the second carrier (132, 232) comprises an attraction element (1321, 2321) and the attraction element (1321, 2321) attracts the first drive magnet (1512, 2512), such that the first carrier (131, 231) and the second carrier (132, 232) are simultaneously in contact with the at least two second rolling elements (1421, 2421).
