DRIVE MECHANISM, CAMERA MODULE AND ELECTRONIC DEVICE Russian patent published in 2020 - IPC G03B3/02 

FIELD: machine building.

SUBSTANCE: invention relates to drive mechanisms for camera module. To this end, the device comprises a drive component, a fixed assembly and a movable assembly, wherein the drive component comprises a resilient conductive element, a closed loop and a magnetic element. At that, closed loop is located in magnetic field created by magnetic element, and is made with possibility of interaction with elastic conducting element for creation of electromagnetic force to overcome elastic force of elastic conducting element, wherein the elastic conductive element is rigidly connected to the fixed assembly and rests against the movable assembly. Besides, the resilient conductive element is configured to actuate the movable unit relative to the fixed assembly during the focusing function in response to the determination that the electromagnetic force exceeds the elastic force of the resilient conductive element, wherein magnetic element comprises two magnetic elements, wherein two magnetic elements are installed on two opposite ends of fixed assembly.

EFFECT: technical result is possibility to reduce size of drive mechanism, facilitating it and reducing thickness, as well as increase in accuracy of photosensitive microcircuit chip.
