Camera modules, electronic devices and equipment for transport vehicles

Abstract

The invention reveals a camera module comprising an image-forming lens assembly with an optical axis and a drive mechanism including a fixing element, lens ring, magnetic bearing mechanism, first ball group, and second ball group. The image-forming lens assembly is arranged within the lens ring. The magnetic bearing mechanism has a first set of grooves extending parallel to the optical axis and a second set of grooves extending perpendicular to the optical axis. One of the fixed parts and the lens ring of the third groove group is positioned opposite the second groove group. The image-forming lens assembly can move relative to the fixed part on a plane perpendicular to the optical axis via the second ball group positioned between the second and third groove groups, and along the direction parallel to the optical axis via the first ball group positioned within the first groove group. The invention also reveals electronic devices including camera modules and transport vehicle devices including camera modules.
