The voice coil motor, it is arranged in the long side cylinder of the L-type optical tubes；
The CIS, after being arranged at the voice coil motor, and focus lens group described in face；
The speculum, it is arranged at the corner of the L-type optical tubes, and its long side with the L-type optical tubes
Cylinder and short side cylinder are set in 45° angle.
Wherein, the camera module also includes convex lens, and the convex lens are arranged at the light inlet of the short side cylinder,
The focus of the convex lens is just on the minute surface of the speculum.
Wherein, layer protecting film is posted on the convex lens.
Wherein, the camera module also includes infrared filter, and the infrared filter is arranged at the focusing
Between lens group and the CIS.
Wherein, the camera module also includes PCB, and the PCB is arranged at the CIS
Rear, and be connected with the CIS.
The utility model is had the following advantages and effect relative to prior art：
The camera module of auto-focusing of the present utility model uses L-type optical tubes, by voice coil motor, focus lens
Group, CIS are located at the long side cylinder of the L-type optical tubes, using speculum by entering from the L-type optical tubes
The light that optical port enters, which reflexes to, carries out focusing process in the focus lens group, so as to allow the focus lens group to possess
Bigger length, so that the camera module has higher multiple, due to the short side cylinder of the L-type optical tubes
Light inlet is set, so the camera module is embedded into mobile phone, can not be limited by mobile phone thickness, hand can be met
Machine is lightening to provide higher focusing multiple while require.
Brief description of the drawings
Fig. 1 is the structural representation of the camera module of auto-focusing of the present utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
