Description
Technical field
The utility model is related to camera technical fields, are imaged more particularly, to the micro-optical with optics debugging functions
The memory alloy wire fixed structure of head mould group.
Background technology
Miniature automatic focusing camera is widely used in the productions such as mobile phone, automobile, unmanned aerial vehicle, safety monitoring, smart home
Among product.Common miniature automatic focusing camera module is moved down in the direction of the optical axis by a miniature voice coil motor driving camera lens
It is dynamic, by controlling the movement of chip drives voice coil motor when taking pictures, to realize automatic focusing function.When taking pictures or imaging, camera lens
Shake or other reasons that can be because of people cannot keep absolutely steady, generate certain deviation, at this time the focusing of camera and light-inletting quantity
It will be affected, and then influence the quality that camera obtains image.General this deflection lens are happened at the side of vertical optical axis
Upwards, automatic Focus voice coil motor can only drive camera lens to move in the direction of the optical axis, therefore can not solve such deflection lens
The problem of causing.Increase an optical anti-vibration actuator on the basis of automatic Focus voice coil motor, driving camera lens is in vertical light
It is moved in the both direction of axis, the above-mentioned deflection of camera lens can be compensated, camera is helped to obtain better image quality, it is this kind of micro-
Type motor of camera is referred to as micro-optical stabilization motor of camera.
The micro-optical stabilization motor of camera of real meaning is a closed-loop control system, and camera lens is detected by gyroscope
Jitter parameter feeds back to camera module control chip, and the positional information calculation that the latter provides according to lens position sensor goes out to mend
Positive angle or displacement simultaneously sends out order-driven stabilization actuator and reaches designated position, to make corrections what camera lens was generated by shake
Displacement deflection makes to take pictures or image to obtain better image quality.
It in the prior art, can also in the both direction of vertical optical axis being moved in optical axis direction with driving camera lens
Using same method, i.e., realized using miniature voice coil motor.Common miniature voice coil motor is by hot-wire coil in magnetic field
Generate the movement of long-range navigation magnetic drive camera lens；And to realize optical anti-vibration, it needs to drive camera lens at least two directions, this meaning
It and needs to arrange multiple coils, integrally-built micromation can be given to bring certain challenge.For this purpose, being carried out using voice coil motor principle
Multiple coils are generally integrated on one piece of circuit board by the micro-actuator of optical anti-vibration, referred to as FP coils, and optics is solved with this
The dimensional problem of stabilization actuator.But miniature voice coil motor optical anti-vibration actuator and the miniature voice coil motor that focuses automatically
The two is separation, and camera lens is often mounted in the miniature voice coil motor focused automatically, to make camera lens in vertical optical axis direction
Upper movement, that is, camera lens is made to be moved with the miniature voice coil motor focused automatically.Therefore, this kind of micro-optical stabilization camera shooting
Head mould group assembly technology is more difficult, also reduces the structural reliability of entire micro motor.Then have using memorial alloy
Silk come the micro-optical camera module that drives automatic Focus voice coil motor move on vertical optical axis direction, as shown in Figure 1, this
Module has protection outer cover 101, camera lens 102, automatic Focus voice coil motor 103, image sensor module 104 and minisize memory
Alloy optical anti-vibration actuator 105, camera lens 102 are fixed on automatic Focus voice coil motor 103, minisize memory alloy optical anti-vibration
Actuator 105 has the camera lens mounting hole that adaptation camera lens 102 is installed, the image that image sensor module 104 obtains camera lens 102
Outflow.The automatic Focus voice coil motor 103 is fixed on above minisize memory alloy optical anti-vibration actuator 105, controls chip
Length based on the memory alloy wire 106 on minisize memory alloy optical anti-vibration actuator 105 changes to pull automatic focusing sound
Coil motor 103 moves, and realizes the jitter compensation of camera lens 102.But the existing micro-optical using memory alloy wire images head mould
Group, or memory alloy wire is fixed, stability is insufficient or fixed structure complicates, inconvenience assembling, so to be improved.
