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 used for mounting the lens and driving the lens to translate in the x-axis direction and the y-axis direction; the second driving part comprises a second base part and a second movable part; the photosensitive assembly is located below the second movable part and installed on the second movable part, the second movable part is suitable for driving the photosensitive assembly to translate in the x-axis direction and the y-axis direction relative to the second base part, and the x-axis and the y-axis are perpendicular to each other and are both parallel to the photosensitive surface of the photosensitive assembly; and the rear shell is located below the second driving part, the rear shell and the second basic part are connected to form a containing cavity, and the second movable part and the photosensitive assembly are both located in the containing cavity. The invention further provides a corresponding assembling method of the optical anti-shake camera module.
Description
[0001] related application [0002] This application is a divisional application of the Chinese patent application No. CN202011097162.3 filed on October 14, 2020, entitled "Drive Structure for Optical Actuator and Corresponding Camera Module". technical field [0003] The invention relates to the technical field of camera equipment, in particular, the invention relates to an optical anti-shake camera module and an assembly method thereof. 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 actuators (sometimes also called motors) to achieve.
