Abstract

The invention provides a zooming device. The zooming device comprises a first lens, a second lens and a hydraulic device. The hydraulic device is arranged between the first lens and the second lens to change the distance between the first lens and the second lens, and the first lens moves away from or towards the second lens under the action of the hydraulic device. The zooming device has the advantages of small volume and simple structure. The invention further relates to a lens module.

Description

technical field [0001] The invention relates to a lens module, in particular to a zoom device and a lens module with simple structure and small volume. 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] For taking images of different magnifications, the camera usually requires a zoom function (see Zoom Lens Systemswith Aspherical Plastic Lens, Consumer Electronics, IEEE Transactions on VolumeCE-33, Issue 3, Aug.1987Page(s): 256-266), realize The zoom function of the camera has two methods: optical zoom and digital zoom. [0004] Optical zoom relies on the structure of the optical lens itself to achieve zooming, that is, the lens in the lens is driven by the driving device to move or the lens barrel is manually rotat...
