Digital camera model group

Abstract

A digital camera module group includes a lens, a driving part and an image sensor. The lens includes a first drawtube, the second drawtube which is some angle with the axis line of the first drawtube and the reflecting device to make the light beam emit from the first drawtube to the second drawtube. The driving part includes a shell, an actuator installed in the shell. The actuator includes a moving part and a stator part. The moving part includes a central axis and many vanes set on the axis; the stator includes at least one side wall and many vanes set on the side wall; the vane of the moving part is parallel with it of the stator part between which has the potential difference; the lens is fixed on the shell of the driving part. The image sensor is fixed on the moving part of the actuator and the lens is imaged on the image sensor.

Description

【Technical field】 [0001] The invention relates to a digital camera module, in particular to a digital camera module for portable electronic devices. 【Background technique】 [0002] At present, mobile phones are developing toward multifunctional trends, and mobile phones equipped with built-in digital cameras are very popular once they are launched. However, due to the size limitation, most of the digital cameras of mobile phones with shooting function are fixed focal length, and the lens with fixed focal length is easy to cause the situation of not being able to focus clearly for imaging, especially for close-up shooting, which will greatly limit the movement Phone's digital camera shot. [0003] The optical focusing mechanism of traditional digital cameras generally uses ordinary transmission devices such as DC motors or stepping motors to drive related optical components to perform focusing actions. It is bulky and consumes a lot of power, so it is not suitable for assemb...

However, due to the size limitation, most of the digital cameras of mobile phones with shooting function are fixed focal length, and the lens with fixed focal length is easy to cause the situation of not being able to focus clearly for imaging, especially for close-up shooting, which will greatly limit the movement The effect of the digital camera of the phone

[0003] The optical focusing mechanism of traditional digital cameras generally uses ordinary transmission devices such as DC motors or stepping motors to drive related optical components to perform focusing actions. It is bulky and consumes a lot of power, so it is not suitable for assembly in mobile phones; And when the number of lenses of the relevant optical element is large, it is also difficult for the transmission device to drive the optical element; in addition, when most digital camera modules perform focusing actions, there will be relative rotation between the lens barrel with the lens group and the image sensor. , due to the eccentricity of the lens group, the lens group may not be aligned with the image sensor
