Description
Technical field
The utility model relates to the camera head of mobile electronic device, relates in particular to a kind of shift shaft type OIS focusing motor.
Background technology
Continuous expansion along with cell-phone function, the photographic effect of mobile phone is more and more drawn close to digital camera, having there are three axle focusing motor in the motor that existing cell-phone camera module adopts, makes cell-phone camera module possess optical image stable (being called for short OIS) function.Current smart mobile phone OIS camera module has two technology paths, and a kind of is based on parallel-moving type (Pure shift) OIS focusing motor, and another kind is based on shift shaft type (Tilt-shift) focusing motor.
The basic principle of parallel-moving type, shift shaft type focusing motor is all to control camera lens with respect to imageing sensor translation, thereby hand is trembled to the image shift canceling compensation causing, falls.But both respectively have quality, although parallel-moving type OIS focusing motor correction scope is large, rectifying effect is good, but its complicated structure, cost is also relatively high, more fatal is because its volume is large, theoretical power consumption is high, speed is slow, can not finely meet desirable frivolous, the demand such as stand-by time is long of existing mobile phone products.And shift shaft type OIS focusing motor simple in structure, be easy to assembling, and move axle photography special efficacy, production cost is also relatively low, favored by manufacturer, but its power consumption is higher, and system is stable not, causes rectifying effect not ideal enough.
Therefore, how providing a kind of cost is industry technical problem urgently to be resolved hurrily compared with the shift shaft type OIS focusing motor low, power consumption is few, stable.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, a kind of shift shaft type OIS focusing motor is proposed, comprise a bottom, be fixed on yoke on bottom, be located at lens mount in yoke, be distributed on described lens mount periphery coil, be located at the yoke inwall magnetite corresponding with described coil, connect the spring leaf of described bottom and lens mount bottom, described bottom is provided with the groove that can hold lens mount, it is peripheral that described spring leaf is fixed on described groove, and the bottom of described lens mount holds up the unsettled top that is positioned at groove by spring leaf.
In the technical program, lens mount is one or eight prisms, and described coil is provided with several, and interval is fixed on the side of eight prism lens mounts.Spring leaf comprises stator and the unsettled support chip above groove that is fixed on described groove periphery, the side bottom that described support chip does not arrange coil at lens mount is respectively equipped with a plurality of, described stator extends an elastic strip near the position of described support chip one end, the other end that this elastic strip extends to support chip is connected with it, the unsettled top that is positioned at described groove of described elastic strip and support chip.The height of groove is greater than 100 microns.
In this another technical scheme, the utility model also comprises the spring leaf that connects described yoke top and lens mount top, and described yoke top is provided with the top groove identical with described groove structure.
The utility model makes lens mount unsettled above bottom in advance by spring leaf, or be suspended on yoke below, motor power consumption is reduced, current drain than multiaxis OIS motor on market is much lower, avoid camera assembly heating, the stable operation of assurance system longer time, and the utility model can be realized and moves axle photography, can realize the camera function of special efficacy, increase the playability of mobile phone photographic.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model;
Fig. 2 is cutaway view of the present utility model;
Fig. 3 is the structural representation of the utility model spring leaf.
Embodiment
As shown in Figure 1 and Figure 2, the utility model one embodiment proposes shift shaft type OIS focusing motor, comprise yoke 1, magnetite 2, spring leaf 3, lens mount 4, coil 5, bottom 6 etc., the bottom 6 that is wherein positioned at below forms a shell with the yoke 1 that is positioned at top, be used for shielding inner and outer magnetic field, lens mount 4 is positioned at yoke 1, and bottom 6 is provided with the groove 7 that can hold lens mount 4, and the bottom of bottom 6 and lens mount 4 is connected by spring leaf 3.
Currently marketed shift shaft type OIS motor exists power consumption to flow problem bigger than normal.Its main cause is, the normal work of height ability that motor need to suspend certain lens mount, and suspension lens mount need to consume the quiescent current that approaches 100mA.When this makes to take pictures, the caloric value of camera module is high, when serious, can have influence on the even stability of machine system of OIS system.And the utility model is provided with the groove that can hold lens mount 4 on bottom 6, the height of this groove is greater than 100 microns, a spring leaf part is fixed on the periphery of groove, a part is unsettled above groove, therefore spring leaf suspends lens mount, makes itself and bottom 6 keep at least surpassing the gap 8 of 100 microns.The existence in this gap has guaranteed that motor do not switch on mobile in the situation that and just can do the inclination of certain angle in focusing direction, realizes such as functions such as OIS, and therefore, than existing scheme on market, power consumption stream significantly reduces, and total power consumption and caloric value all decline to a great extent.
In the present embodiment, lens mount 4 is eight prisms, and those skilled in the art can arrange according to the side at lens mount corresponding coil, such as 2,4 etc., the coil 5 of the present embodiment is provided with 4, and interval, non-conterminous ground is fixed on 4 sides of eight prism lens mounts 4.Inwall in yoke 1 is provided with the 4 block magnetites 2 corresponding with coil 5, when each coil electricity, the relative pole polarity of its surrounding makes each coil can drive respectively lens mount to do straight line focusing motion with respect to motor case, and inclination or translational motion on two orthogonal directions.The bottom of lens mount 4 holds up unsettled above the groove 7 of bottom 6 by spring leaf 3.
As shown in Figure 3, spring leaf 3 comprises stator 31 and the unsettled support chip 32 above groove 7 that is fixed on groove periphery, the side bottom that support chip 32 does not arrange coil 5 at lens mount 4 is respectively equipped with 4, stator 31 extends an elastic strip 33 near the position of support chip 32 one end, the other end that this elastic strip extends to support chip is connected with it, adjust the resilient property of elastic strip, until adjust to whole suspension, allow lens mount to do or translational motion on two orthogonal directions perpendicular to optical axis with respect to motor case, order to lens mount 4, when not switching on, be just naturally suspended in groove 7 above, and yoke 1 has structurally been reserved enough camera lens inclined spaces, realized motor effect of current sinking not substantially under the state of normally taking pictures, power consumption and the caloric value of whole system significantly reduce, also make the more stable work of OIS system.
In another embodiment of the present utility model, between yoke top and lens mount top, also can connect by spring leaf, and yoke top is provided with the top groove identical with groove 7 structures.Make in lens mount suspension and the unsettled shell being formed by yoke and bottom.
Above specific embodiment is only in order to illustrate structure of the present utility model, and those of ordinary skill in the art can make various deformation and variation under design of the present utility model, and these distortion and variation include within protection range of the present utility model.
