Reflective module, reflective driving assembly, and camera module

Abstract

This application discloses a reflective module and a camera module. Particularly, the reflective module comprises: a reflective element and a reflection driving assembly; wherein the reflective element reflects the light rays propagating in a direction of a first axis to a direction of a second axis intersecting with the first axis at a certain angle, and the reflection driving assembly comprises a reflection base, a frame supporting the reflective element and capable of rotating around the first axis, and a shaft support member and at least two auxiliary balls which are provided between the reflection base and the frame. Particularly, the shaft support member is passed through by the first axis and fixed to the reflection base or frame; and the at least two auxiliary balls are provided between at least two auxiliary upper grooves of the frame and at least two auxiliary lower grooves of the reflection base, wherein one of the at least two auxiliary upper grooves and at least two auxiliary lower grooves are straight-line grooves extending along a tangent direction of a virtual circle centered on the first axis.
