Fig. 1 shows camera lens anti-shake apparatus the showing when elastic slice position-limit mechanism is not used according to presently filed embodiment
Meaning property top view.
As shown in Figure 1, the camera lens anti-shake apparatus includes elastic slice component and the SMA wire around the setting of elastic slice component.Elastic slice component
Extend with the hole 110 for accommodating camera lens (not shown), the elastic slice main body 120 around hole 110 and from elastic slice main body 120
The first elastic slice cantilever 121 and the second elastic slice cantilever 122.SMA wire and elastic slice component around the setting of elastic slice component have four companies
Contact, the tie point of one of diagonal angle are static tie point 310 Hes constant relative to the movement holding position of SMA wire
330, the tie point of another diagonal angle is the removable tie point 320 and 340 of the movement with SMA wire and movement.SMA wire connection
Static tie point 310 and 330 at one group of angle steel joint being located on the outside of elastic slice component, and it is another on the outside of lens module
Removable tie point 320 and 340 at one group of angle steel joint.SMA wire includes four sections of SMA wires 210,220,230 and 240 as a result,.?
When SMA wire is shunk, apply pulling force to corresponding removable tie point, thus corresponding removable tie point with SMA wire receipts
It contracts and moves.The fixing end of first elastic slice cantilever 121 extends near removable tie point 320 from elastic slice main body 120, around elastic slice
It is extended on the outside of main body 120 near removable tie point 340, the free end of the first elastic slice cantilever 121 is in removable tie point 340
Nearby it is fixedly connected on SMA wire 240.In the opposite side of the first elastic slice cantilever 121, the fixing end of the second elastic slice cantilever 122 is removable
Dynamic tie point 340 nearby extends from elastic slice main body 120, is extended near removable tie point 320 on the outside of elastic slice main body 120,
The free end of second elastic slice cantilever 122 is fixedly connected on SMA wire 220 near removable tie point 320.It is driven in SMA wire
In the case where, camera module moves on the direction perpendicular to optical axis under the drive of SMA wire.
Following table is enumerated the corresponding elastic slice direction of motion under each SMA wire state.It should be appreciated that SMA wire and elastic slice are only
In the flat in-plane moving perpendicular to optical axis.Motor carrier and its interior camera lens are fixed in elastic slice main body and move therewith, realize anti-
It trembles.

Specifically, in situation 1, when four SMA wires are in elongation state, do not apply additionally to four points of connection
Power, therefore elastic slice keeps centered position.In situation 2, the contraction of SMA wire 210 and 220 so that removable tie point 320 by
To upward pulling force and removable tie point 340 is by pulling force to the left, thus elastic slice upper direction to the left.In situation 3,
SMA wire 220 is shunk so that removable tie point 320 is by upward pulling force, and removable point 340 does not stress, thus bullet
Piece moves upwards.In situation 4, the contraction of SMA wire 220 and 230 make respectively removable tie point 320 by upwards and to
Right power, thus elastic slice upper direction to the right under the action of resultant force.In situation 5, the contraction of SMA wire 230 is so that removable
Tie point 320 is by power to the right, and thus elastic slice moves right.In situation 6, the contraction of SMA wire 230 and 240 is so that removable
Dynamic tie point 320 by power to the right and removable tie point 340 it is subject to downward force, thus elastic slice moves to the right.
In situation 7, the contraction of SMA wire 240 makes removable tie point by downward pulling force, and thus elastic slice moves downward.In situation 8
In, the contraction of SMA wire 210 and 240 make respectively removable tie point 340 by the left with downward power, so that elastic slice is closing
Moved beneath to the left under the action of power.In situation 9, the contraction of SMA wire 210 so that removable tie point 340 by the left
Power, thus elastic slice moves downward.
