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 an optical anti-shake camera module. The optical anti-shake camera module comprises a lens; a photosensitive component; the first driving part is suitable for mounting the lens and driving the lens to translate in the x-axis direction and the y-axis direction; the second driving part is suitable for driving the photosensitive chip to translate in the x-axis direction and the y-axis direction, the second driving part comprises a second basic part and a second movable part, the second basic part comprises a base and a cover, 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 top of the cover is connected with the first driving part; the second movable part is movably connected with the second base part through the balls, and the moving freedom degree is limited in the xoy plane through the balls. Wherein the lens and the photosensitive chip are configured to be driven at the same time and move towards opposite directions; the balls are located on the outer side of the outer side face of the photosensitive assembly. According to the invention, the anti-shake stroke and the anti-shake response speed of the camera module can be improved, and the height of the camera module can be reduced.
Description
technical field [0001] The invention relates to the technical field of camera equipment, in particular, the invention relates to an optical anti-shake camera module. Background technique [0002] 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 actuators (sometimes also called motors) to achieve. [0003] figure 1 A typical camera module with a motor in the prior art is shown. refer to figure 1 , the camera module generally includes a lens 1 , a motor mechanism 2 (which may be referred to as a motor for short) and a photosensitive component 3 . When the camera module is in the shooting st...
