Problems solved by technology
However, the current electronic devices (such as mobile phones) also have great restrictions on the volume of the camera module, and the occupied volume of the motor increases correspondingly with the increase of the lens.
In other words, with the trend of lenses becoming larger and heavier, it is difficult for the driving force provided by the motor to increase accordingly
Under the premise that the driving force is limited, the heavier the lens, the shorter the motor can drive the lens to move, which affects the anti-shake ability
On the other hand, the heavier the lens, the slower the motor can drive the lens to move, and the longer it takes for the lens to reach the predetermined compensation position, which will also affect the anti-shake effect

The invention relates to a driving structure for an optical anti-shake camera module, and the structure comprises a second driving part which is suitable for driving a photosensitive chip to translate in x-axis and y-axis directions, the second driving part comprises a second basic part and a second movable part, the second basic part comprises a pedestal and a cover, and the second movable part comprises a first driving part and a second driving part; at least one part of the base is located below the photosensitive assembly, the bottom of the cover is connected with the base, and the second movable part is movably connected with the second basic part through a ball; and the second base part, the ball and the second movable part are sequentially supported in the z-axis direction. The invention also provides a corresponding camera module. According to the invention, shake prevention can be carried out by using the movement of the photosensitive chip, the photosensitive chip does not need to be inclined, and the problem of image paste caused by shake prevention movement is avoided.
Description
[0001] related application [0002] This application is a divisional application of the parent application of the Chinese patent application number CN 202011231140.1, which is entitled "Optical Image Stabilization Camera Module" and was submitted on November 6, 2020. technical field [0003] The present invention relates to the technical field of photographing equipment, in particular, the present invention relates to a driving structure for an optical anti-shake camera module and a corresponding camera module. Background technique [0004] With the increasing demand of consumers for mobile phone photography, the functions of mobile phone cameras (that is, camera modules) are becoming more and more abundant. Functions such as portrait shooting, telephoto shooting, optical zoom, and optical image stabilization are all integrated into the camera with limited size. , and functions such as autofocus, optical image stabilization, and optical zoom often need to rely on optical act...
