Abstract
Disclosed are a reflection driving mechanism and a camera module. The reflection driving mechanism drives the reflective element of the camera module to rotate through a compact structural arrangement to achieve optical image stabilization of the camera module. Furthermore, the reflective stabilization mechanism has a relatively small size, which is conducive to the miniaturization of the camera module.

-37. (canceled)
A reflection driving mechanism, comprising:
- a reflection drive housing having a receiving cavity formed therein and a light inlet and a light outlet communicated with the receiving cavity;
- a rotation support assembly;
- a support frame, which is rotatably mounted in the receiving cavity through the rotation support assembly, wherein the support frame has at least one support groove recessedly formed on its top surface;
- a bearing seat rotatably mounted on the support frame, wherein the bearing seat comprises a bearing body and at least one rotation axis protruding and extending laterally from the bearing body, the bearing body has a mounting portion suitable for mounting a reflective element thereon, and the at least one rotation axis is fittedly mounted in the at least one support groove, so that the bearing seat can rotate relative to the support frame through the pivot connection between the at least one rotation axis and the at least one support groove;
- and
- a driving unit, wherein the driving unit is suitable for driving the bearing seat to rotate relative to the support frame around a first axis set by the at least one rotation axis, and the driving unit is suitable for driving the bearing seat to rotate relative to the reflection drive housing around a second axis perpendicular to the first axis so as to drive the support frame to rotate relative to the reflection drive housing around the second axis through the pivot connection between the bearing seat and the support frame.
