Driving module, image acquisition device and electronic equipment

Abstract

The invention relates to a driving module, an image acquisition device and electronic equipment. The driving module comprises a base, a carrier and a driving assembly, wherein the base comprises a guide part and a protruding part, and the protruding part is fixedly arranged on the guide part and protrudes relative to the guide part; the carrier is embedded with the guide part, is used for mounting a lens module and comprises a contact surface, and the contact surface is arranged along the direction of the optical axis and is opposite to the protruding part; and the driving assembly is arranged between the base and the carrier and is suitable for driving the carrier to move along the direction of the optical axis, and the carrier is driven by the driving assembly to move relative to the protruding part. The image acquisition device comprises a lens module and the driving module, wherein the lens module is mounted on the carrier. The electronic equipment comprises a shell, a display screen and the image acquisition device, wherein the display screen is connected to the shell, and the image acquisition device is arranged in the shell. According to the driving module, the guide part and the protruding part are used as a whole to replace a special sliding guiding structure, so the part structure of the driving module is simplified.

Description

technical field [0001] The present application relates to the technical field of photographing equipment, in particular to a driving module, an image acquisition device and electronic equipment. Background technique [0002] With the continuous development of electronic technology, auto-focus technology is widely used in image acquisition devices of electronic equipment such as smart phones and tablet computers. At present, electronic devices with voice coil motors are becoming more and more common, and the voice coil motors used for autofocus show a trend of rapid development. [0003] However, at present, most of the autofocus units of voice coil motors use a proprietary sliding guide structure. Such a slide guide structure usually includes moving parts and a track assembly. The moving parts move in the track assembly, resulting in many parts and complex structures of the voice coil motor. Contents of the invention [0004] Embodiments of the present application provide...
