Title:
LENS DRIVING ASSEMBLY, CHIP DRIVING ASSEMBLY, CAMERA MODULE, AND BALL-BASED TWO-AXIS OPTICAL ACTUATION MODULE
Document Type and Number:
WIPO Patent Application WO/2023/274421
Kind Code:
A1
Abstract:
Disclosed in the present invention are a rotating mechanism and a camera module thereof, a driving apparatus and an electronic device thereof, and a ball-based two-axis optical actuation module. The driving apparatus is configured to drive a light diverting mechanism, and the driving apparatus comprises at least one group of coils, at least one group of magnets, at least one guide groove and at least one supporting mechanism. The coils are provided on the periphery of the light diverting mechanism and are parallel to a first rotation axis. Each group of magnets and each group of coils are provided opposite to each other and can drive the light diverting mechanism to rotate. The supporting mechanism is movably engaged with the guide groove. The guide groove uses the first rotation axis and/or a second rotation axis as a central axis. The guide groove guides the rotation direction of the light diverting mechanism. When the coils are energized, the magnets are driven to drive the light diverting mechanism to rotate around the first rotation axis and/or around the second rotation axis. Therefore, by adjusting the rotation of the light diverting mechanism at two degrees of freedom, optical image stabilization of an optical lens along a direction of a plane orthogonal to an optical axis is realized, and the height of a camera module is reduced.
