Problems solved by technology

However, these functions are currently realized by moving the lens with the voice coil focus motor, but at the same time, new problems that are difficult to solve have arisen. For example, the motor is difficult to be completely dust-proof, so during use, the image sensor surface May be scrapped due to falling dust
In addition, the motor needs a matching lens to form a camera module, s

Embodiment Construction

[0018] The structural principle of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 As shown, the mobile terminal camera module of the present invention includes a lens 1 arranged in sequence, a voice coil motor 2 for fixing or controlling the movement of the lens, an image sensor 303 for imaging, an FPC soft board 309, a drive module, and a lens The light of 1 is transmitted to the image sensor 303 for imaging, and the driving module has a coil and a magnet. The coil and the magnet generate force to drive the image sensor to achieve focusing, and can also drive the image sensor to move horizontally or vertically in a plane perpendicular to the optical axis. To achieve two-dimensional optical image stabilization, further, it can also drive the image sensor to rotate around its exact center in a plane perpendicular to the optical axis. The invention keeps the lens still while moving the image...

Abstract

The invention discloses a camera module for a mobile terminal. The camera module comprises a lens, a voice coil motor for fixing the lens or controlling the lens to move, an image sensor for imaging and an FPC (Flexible Printed Circuit) board which are arranged in sequence, wherein the lower side of the image sensor is movably connected with the FPC board. The module also comprises a driving module, wherein the driving module is provided with a coil and a magnet; and an acting force is generated through the coil and the magnet to drive the image sensor to move in a reciprocating way along a direction parallel to an optical axis in order to realize an automatic focusing function, or drive the image sensor to move in the transverse or longitudinal direction in a plane vertical to the optical axis and rotate around a center point, thereby realizing three-dimensional optical vibration prevention. The invention also provides the mobile terminal using the camera module. The camera module is simple in structure, small in size and convenient to match.

Description

technical field [0001] The invention relates to accessories of electronic products, in particular to a camera module of a mobile terminal and the mobile terminal. Background technique [0002] At present, various types of mobile terminal products emerge in endlessly, and their respective functions are also constantly evolving. People's requirements for various mobile terminal hardware facilities are also constantly improving. For example, the pixels of tablets and smart phones can also reach the level of digital cameras. , so people are more willing to use tablet computers or smart phones to realize the camera function. [0003] However, the photographing effect of existing tablet computers and smart phones is always inferior to that of digital cameras, because the overall volume of digital cameras is much larger than that of smart phones. Multi-dimensional movement enables digital cameras to implement optical image stabilization (OIS) and tilt-shift photography technologie...
