Camera shooting module, camera shooting device and electronic device

Abstract

The invention discloses a camera shooting module, a camera shooting device and an electronic device. The camera shooting module comprises a base, a lens, a lever and a driving part, the base is provided with a first rotating part, the lens is movably arranged on the base, the lever is provided with a second rotating part, the second rotating part is rotatably connected to the first rotating part, one end of the lever is connected to the lens, the driving part is arranged on the base, and the driving part is arranged on the base. The driving part is connected to the other end of the lever and used for pushing the lever to rotate around the first rotating part so as to drive the lens to move relative to the base in the optical axis direction. According to the camera shooting module, the camera shooting device and the electronic device provided by the invention, the pushing force for pushing the lens to move is large, so that the movement distance of the lens is long, the stroke of the lens is increased, and the long-focus range focusing requirement of the lens can be met. And moreover, the driving part and the lever are matched with each other, so that the focusing effect of the camera module is realized, the structure is simple, the assembly is convenient, and the reliability is better.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a camera module, a camera device and electronic equipment. Background technique [0002] At present, most photographing devices (such as digital cameras, mobile phones, tablet computers, etc.) usually use a voice coil motor (Voice Coil Motor, VCM) to drive the movement of the lens to realize the auto-focus function of the camera module. A common voice coil motor mainly includes a coil and a magnet, and the thrust generated by the magnet through the electrification of the coil drives the lens to move, thereby realizing autofocus. [0003] However, during the focusing process, the relative distance between the coil and the magnet will become longer and longer, resulting in the possibility that the thrust generated by the coil on the magnet will become smaller and smaller. Therefore, the voice coil motor in the related art is usually only suitable as a The short-distance drivin...

Problems solved by technology

[0003] However, during the focusing process, the relative distance between the coil and the magnet will become longer and longer, resulting in the possibility that the thrust generated by the coil on the magnet will become smaller and smaller. Therefore, the voice coil motor in the related art is usually only suitable as a The short-distance driving device in the camera module has a short stroke, which is difficult to meet the long-stroke telephoto focusing requirements
