Lens module and camera module

Abstract

The invention provides a lens module, comprising a lens holder and a carrier disk. The lens holder has an incidence opening, and the carrier disc is arranged in the lens holder and has a plurality of all-in-one lenses with different curvatures distributed along the circle. The carrier disc can rotate along a rotary shaft to make the plurality of lenses respectively aligned to the incidence opening of the lens holder. The lens module realizes the zooming operation through the rotating of the carrier disc. Thickness along the direction of an optical axis is not required to be changed in the zooming of the lens module, favoring the thinning of the lens module. In addition, the invention also provides a camera module by using the lens module.

Description

technical field [0001] The invention relates to the field of photography, in particular to a lens module and a camera module using the lens module. Background technique [0002] With the development of camera technology, camera modules are widely used in camera devices for various purposes. The combination of camera modules and various portable electronic devices such as mobile phones, video cameras, computers, etc. is favored by many consumers. . [0003] The technology of mobile phone camera modules is getting more and more developed. At present, models with auto focus and 5 megapixels have come out. In many applications, a zoomable mobile phone camera module is also required, but it is very difficult to achieve optical zoom in the small space of a mobile phone. Although some two-stage zoom lenses are currently used in mobile phone camera modules, they generally require precise cam structures and complex assembly, which is not conducive to mass production, especially in ...

In many applications, a zoomable mobile phone camera module is also required, but it is very difficult to achieve optical zoom in the small space of a mobile phone

Although some two-stage zoom lenses are currently used in mobile phone camera modules, they generally require precise cam structures and complex assembly, which is not conducive to mass production, especially in these zoom mobile phone camera modules. The barrel moves along the direction of the optical axis, resulting in a large thickness of the camera module of this type of mobile phone along the direction of its optical axis, which cannot meet the needs of light, thin and short mobile phones
