The drive apparatus is used in the camera module, the camera module includes a plurality of lens group assemblies, and the drive apparatus includes: a drive part, a move part, and a transmission assembly. The drive part is configured to provide a driving force, to drive the move part to move along an optical axis direction of the camera module, and the transmission assembly is in a transmission connection to the move part and at least one of the plurality of lens group assemblies, so that relative locations of the move part and the at least one lens group assembly in the optical axis direction of the camera module are fixed, and the move part and the at least one lens group assembly may move relative to each other in another direction. According to the drive apparatus provided in this application, the transmission assembly is disposed between the move part and the lens group assembly, so that the move part of the drive apparatus is decoupled from the lens group assembly in a direction other than the optical axis direction of the camera module, to prevent a case in which the move part and the lens group assembly are stuck because a moving direction of the move part deviates from the optical axis direction of the camera module.

摘要： This application provides a variable aperture, a camera module, and an electronic device. The variable aperture includes a fixing base, a rotating support, a mover, a stator, and a plurality of blades. The rotating support is disposed on an inner side of the fixing base. In this way, on one hand, the rotating support does not interfere with components on an outer side of the fixing base, thereby ensuring accuracy of a rotation angle of the rotating support in a rotating process; and on another hand, the components on the outer side of the fixing base may be disposed close to the fixing base, and the components are arranged more compactly, thereby facilitating miniaturization of the variable aperture. In addition, the mover is fixedly connected to an outer peripheral side surface of the rotating support, and the stator is disposed facing the mover. In this way, on one hand, stacking of the mover and the stator in a thickness direction of the camera module is avoided; and on another hand, the mover, the stator, the fixing base, and the rotating support may be arranged more compactly.
