Detailed description of the invention
Below in conjunction with the accompanying drawings and the case of electronic device of the present invention is described in further detail by embodiment.
Referring to Fig. 2, the dual shot device 30 of first embodiment of the invention includes main circuit board 31, is arranged on main electricity
Controller 32, two the camera lens modules 33 being arranged on main circuit board 31 on road plate 31, it is respectively arranged at two camera lens modules
Two position sensors 34 on 33, two camera lenses being arranged on main circuit board 31 and being connected with two camera lens modules 33 respectively
Two pieces of flexible PCBs 36 of module leaning device 35, link position sensor 34 and main circuit board 31.In the present embodiment, position
Sensor 34 is Hall element.
These two camera lens module leaning devices 35 are symmetricly set in the both sides of main circuit board 31.Each camera lens module dumper
Structure 35 include location-plate 352 that the bracing frame 351 being arranged on main circuit board is connected with camera lens module 33, be movably set in fixed
Position plate 352 on the first roller 353 and the second roller 354, around be located on the first roller 353 first regulation line 355, around being located at
On second roller 354 second regulates line 356 and the elastic component 357 being connected between bracing frame 351 and location-plate 352.First
The two ends of regulation line 355 are individually fixed in the both sides of bracing frame 351.The two ends of the second regulation line 356 are individually fixed in bracing frame
The both sides of 351.In the present embodiment, the first regulation line 355 and the second regulation line 356 are by marmem (SMA, Shape
Memory Alloy) make.Therefore, after the first regulation line 355 and the second regulation line 356 are heated, its length can be stretched,
And can recover to original length after cooling.Above-mentioned marmem can be Nitinol, silver-cadmium alloy, ormolu and copper
Ashbury metal etc..Elastic component 357 is two, and it is respectively arranged at the two ends of location-plate 352, and is in compressive state and has one
Presetting elastic force, in the present embodiment, elastic component 357 is spring.Refer to Fig. 3, when the depth of field of dual shot device 30 cannot expire
When object nearby is shot by foot, controller 32 controls heating member (not shown) to the first regulation according to the image photographed
Line 355 heats, and the first regulation line 355 deliquescing after heating, at the default elastic force of the elastic component 357 near the first roller 353
Under effect, the length of the first regulation line 355 is stretched, owing to the length of the first regulation line 355 increases, and the second regulation line 356
Length keep constant, camera lens module 33 is by relative support frame 351 run-off the straight, so that the scape of dual shot device 30
Deeply change.Two camera lens modules 33 in Fig. 3 increase due to the length of the first regulation line 355, all near the first roller
The side run-off the straight of 353, now minimum depth of field H of dual shot device 30 will diminish, thus be conducive to shooting nearby
Object.In the tilting procedure of camera lens module 33, the real time position letter of the camera lens module 33 that position sensor 34 is sensed
Breath is transferred to controller 32 by flexible PCB 36 and main circuit board 31, when camera lens module 33 tilts to precalculated position, and control
Device 32 processed controls heating member and stops heating, and controls camera lens module 33 and shoot corresponding near objects.After having shot, due to
One regulation line 355 gradually cools down, and it can recover to original length, and camera lens module 33 also can be returned to original position.
It is appreciated that the first regulation line 355 and the second regulation line 356 also can be made up of other metal materials such as copper, elastic
Part 357 also can omit, and now, one end of the first regulation line 355 can be fixed to bracing frame 351, and the other end is connected to a volume
Line wheel (not shown), and one end of the second regulation line 356 is fixed to bracing frame 351, the other end is connected to another spiral
Wheel.The rotation of two reels is controlled by controller 32, to regulate the first regulation line 355 and length of the second regulation line 356,
Thus regulate the depth of field of dual shot device 30.
Referring to Fig. 4, the dual shot device 40 of second embodiment of the invention includes main circuit board 41, is arranged on main electricity
Controller 42, two the camera lens modules 43 being arranged on main circuit board 41 on road plate 41, it is respectively arranged at two camera lens modules
Two position sensors 44 on 43, two camera lenses being arranged on main circuit board 41 and being connected with two camera lens modules 43 respectively
Two pieces of flexible PCBs 46 of module leaning device 45, link position sensor 44 and main circuit board 41.
Camera lens module leaning device 45 includes four drivings being arranged between two camera lens modules 43 and main circuit board 41
Part 451, two of which actuator 451 is respectively arranged at the two ends, bottom of a camera lens module 43, two other actuator 451 points
It is not arranged at the two ends, bottom of another camera lens module 43.In the present embodiment, actuator 451 is piezoelectric motors.It is appreciated that
Camera lens module leaning device 45 may also comprise the actuator 451 of more than four.
When the depth of field of dual shot device 40 cannot meet and shoot adjacent or remote object, controller 42
Control actuator 451 according to the image photographed the angle of inclination of camera lens module 43 is adjusted, so that twin-lens is clapped
The depth of field taking the photograph device 40 changes.In the tilting procedure of camera lens module 43, the camera lens that position sensor 44 is sensed
The real-time position information of module 43 is transferred to controller 42, when camera lens module 43 inclines by flexible PCB 46 and main circuit board 41
During tiltedly to precalculated position, controller 42 controls actuator 451 stop motion, and control camera lens module 43 shoot corresponding the most nearby or
Distant objects.After having shot, controller 42 controls actuator 451 and moves so that camera lens module 43 is returned to original position.
It addition, those skilled in the art also can do other change in spirit of the present invention, certainly, these are according to present invention essence
