Topic is exactly it cannot be guaranteed that the optical axis of two voice coil motors is parallel to each other, so as to influence image synthesis；The size at voice coil motor inclination angle
The imaging effect of last camera is directly affected, due to the presence of build-up tolerance, causes motor to be completed rear lens carrier
It is bound to certain inclination angle be present（Camera lens carrier center axle is best perpendicular to lower surface, but after voice coil motor assembling, camera lens carries
Body central shaft can all have certain inclination relative to motor lower surface）.
As shown in figure 1, existing achievable voice coil motor tilt adjustable mainly passes through the base in the bottom of voice coil motor 1 '
Increase by a pair of spheres 2 ', adjust whole voice coil motor 1 ', first two angles of fixed voice coil motor 1 ' are motionless, then by pressing in addition
Two angles（Because base is sphere-contact during pressing, can slide）The function of adjustable inclination is realized, but its structure becomes more
Complexity, and add the integral thickness of voice coil motor；Moreover, its reliability and less stable, prior art is being adjusted
Voice coil motor 1 ' and sphere 2 ' are fixed by the gap dispensing between voice coil motor 1 ' and sphere 2 ' behind inclination angle, but due to gap
Presence, the problems such as glue is flexible, strictly to be controlled by pressure request, if pressing is not controlled, voice coil motor 1 ' inclines
Angle can change again, cause after making camera, can still there is certain inclination angle, it is impossible to ensure two voice coil motors
Optical axis is parallel to each other, therefore, it is necessary to propose that one kind is simple in construction, and do not increase the adjustable inclination angle of voice coil motor integral thickness
Voice coil motor, to solve the deficiencies in the prior art part.

The present invention has the advantages that：The voice coil motor is by increasing by a shell with deep-slotted chip breaker and with song
The base of face is engaged, and realizes tilt adjustable, simple in construction easy to operate, has high unfailing performance and stability, further
Improve the imaging effect of camera particularly dual camera；Its is simple in construction, it is easy to accomplish, ease of assembly, present invention regulation is inclined
Angle is in voice coil motor chassis side, and after having adjusted inclination angle, change of pitch angle will not be caused because of external force, ensures regulation rear camera not
Occur inclination angle problem again, ensure that the optical axis of two voice coil motors is parallel particularly when applied to dual camera, solve existing
Dispensing technique for fixing needs strict technology requirement and the problem of certain inclination angle still be present after the completion of adjusting technology adjustable inclination again.
Can be almost nil with adjustable inclination after being completed, then fix, production efficiency and voice coil motor quality are further improved, reduces life
Cost is produced, there is good economic benefit.
