Fig. 3 is the planimetric map of front side spring 3.The formation of rear side spring 9 is also almost identical with the formation of front side spring 3, so, quote the explanation of front side spring 3 and the description thereof will be omitted.Front side spring 3 is a kind of with the tabular body of thickness direction as optical axis direction.Front side spring 3 comprises: be fixed on the front end of lens mount 8 and the moving body sidepiece 13 that lens mount 8 moves to optical axis direction together; Be fixed on the fixed body sidepiece 14 on the collar extension 4; The thin tabular wrist 15 that connects moving body sidepiece 13 and fixed body sidepiece 14.Accordingly, moving body sidepiece 13 is fixed on the moving body 30, fixed body sidepiece 14 is fixed on the fixed body 31.In addition, wrist 15 is configured to a plurality of at Zhou Fangxiang.In this example, wrist 15 is 4.In addition, the wide cut W of wrist 15 is larger than thickness H.Such as, the degree of W:H=1.5:1.
As shown in Figure 3, wrist 15 comprises: in the central elastic section 23, the 1st inversion portion 20 and the 2nd inversion portion 21 that form along summary Zhou Fangxiang.An end of the 1st inversion portion 20 connects to moving body sidepiece 13, and another end connects to central elastic section 23.In addition, an end of the 2nd inversion portion 21 connects to fixed body sidepiece 14, and another end connects on another end of central elastic section 23.The 1st inversion portion 20 is along the sweep 16 by counter-rotating start portion 201 and end of a period section 202, have vertical be located at above-mentioned optical axis direction by the bending part 17 of bending.The 2nd inversion portion 21 is along the sweep 18 by counter-rotating start portion 203 and end of a period section 204, have vertical be located at above-mentioned optical axis direction by the bending part 19 of bending.
Shape before the bending of bending part 17 is circular-arc in this example, thus with this as arc sections 22.Therefore, the face of bending part 17 relative front side springs 3 vertically vertical be located at circular-arc.In addition, the vertical direction size of bending line 16 is equivalent to thickness H.
Fig. 1 is the key diagram after the 1st inversion portion 20 of the 1st inversion portion when arc sections 22 is made bending part 17 of ready-made arc sections 22 compared.Fig. 1 (a) is the figure that arc sections 22 is not carried out bending.Under this occasion, such as the situation of the external force F effect that will consider from space below shock and vibration etc. upward to the counter-rotating start portion 201 of figure.In such cases, in Fig. 3, the interior all sides that have a radial direction begin towards the bearing of trend of the start portion 201 of outer circumferential side, i.e. the external force F generation effect of the mobile moving body sidepiece 13 in top, direction space under the space.The power that namely to be a kind of lens mount 8 move from interior all side direction outer circumferential sides of radial direction.This kind situation, 3 powers of the wide cut W in the arc sections 22 of wrist 15 work as the spring force that stops external force F.In the occasion of this example, it is the relation of W:H=1.5:1, so compare with the situation that stops external force F on thickness direction, 3 times of difficulties are wanted in the elastic deformation of arc sections 22, and these external force F is difficult to be absorbed.
Fig. 1 (b) be with arc sections 22 by the start portion 201 of counter-rotating and the optical axis direction of the bending line 16 of end of a period section 202, namely in front of the space after the side bending as the figure of bending part 17.In this case, top, direction space external force F under the space is in case the start portion 201 to figure acts on, and bending part 17 will be shown in Fig. 1 (c), and start portion 201 will be moved upward by the below, space.End of a period section 202 with mobile just distortion, produces elastic deformation hardly after absorbing external force F.That is, 3 powers of the thickness H in the bending part 17 of wrist 15 work as the spring force that stops external force F.In above-mentioned arc sections 22, to compare with the occasion that stops external force F, it is easy more than 3 times that the elastic deformation of its bending part 17 is wanted, and easily its external force F absorbed.In addition, in a single day external force disappear, and shown in Fig. 1 (c), the bending part 17 of distortion is shown in Fig. 1 (b), and elastic force will be restored.For this reason, wrist 15 is difficult to plastic yield, can prevent the plastic deformation of front side spring 3.For this reason, can shock-resistant and vibration.
In addition, bending part 17 is located at optical axis direction because only pass through fixed position bending establishment, so can realize high-precision bending, can reduce the spring performance deviation of front side spring 3.
Wrist 15 as above-mentioned has the 2nd inversion portion 21.Owing to having the 1st inversion portion 20 and the 2nd inversion portion 21 that is connected on the fixed body sidepiece 14 on the moving body sidepiece 13 that is connected to wrist 15, therefore can just can absorb external force F by the 1st inversion portion 20 and the 2nd inversion portion 21 these two aspects.External force F is difficult to be communicated in the central elastic section 23.
Further, different each other with the bearing of trend from the front projection of the optical axis direction of the bending part 19 of the 2nd inversion portion 21 from the bearing of trend of the front projection of the optical axis direction of the bending part 17 of the 1st inversion portion 20.For this reason, even if external force F adds up from the direction of light shaft positive cross etc., at least one of at least the 1 inversion portion or the 2nd inversion portion 21 can absorb external force F.In brief, such as, paralleling on the direction (paralleling direction with bending line 16) in the bending part 17 of the 1st inversion portion 20 and to apply external force F, the 1st inversion portion is as being difficult to absorb external force F, and another the 2nd inversion portion 21 just can absorb external force F.Therefore, lens driver 1 can anti-stronger shock and vibration.
The utility model is not limited to above-mentioned example, only otherwise break away from the possibility that purport of the present utility model can be done all distortion.Such as, as mentioned above, the formation of the front side spring 3 in the utility model example also can be applied to rear side spring 9.In addition, the front side spring 3 in the utility model example, be applicable to carry out lens automatically focusing, use on the lens driver 1 on the auto-focus camera device.Further, for the portrait dislocation that is caused by client's hand wobble, on the lens driver 1 that can proofread and correct, be applicable to the auto-focus camera device.Such as, drive division 32 is a kind of, lens mount 8 be attached to make the drive coil 7 that moves to optical axis direction, the electromagnetic force of generation make mobile to the formation of the 2nd drive coil of optical axis direction phase orthogonal directions on.Stop mobile when like this, lens mount 8 reaches equilibrium locations between the elastic force of this electromagnetic force and front side spring and rear side spring 9.
In addition, example as shown in Figure 3, wrist 15 has central elastic section 23 and the 1st inversion portion 20, the 2nd inversion portion 21.The 1st inversion portion 20 has bending part 17.The 2nd inversion portion 21 has bending part 19, but is not limited to this.One side that also can only be the 1st inversion portion 20 or the 2nd inversion portion 21 has bending part 17 or bending part 19.In addition, after wrist 15 arranges the 3rd, the 4th inversion portion, also can be the formation with the 3rd, the 4th bending part.In addition, after removing central elastic section 23, the 1st inversion portion 20 is connected with the 2nd inversion portion 21.In addition, the 1st inversion portion 20, the 2nd inversion portion 21 directly interconnect moving body sidepiece 13 and fixed body sidepiece 14.Also can pass through other parts, moving body sidepiece 13 and fixed body sidepiece 14 interconnect.
In addition, bending part 17 as shown in Figure 3, unnecessary make circular-arc, as Fig. 4 (a) the shape before the bending that is shown in can make V word shape.In addition, shown in Fig. 4 (b), are connected with end of a period section and connect in line shape in the start portion 201 that is shaped as that also can be before bending.This part is as linearity section 24.After linearity section 24 is set, bending line 16 is arranged near linearity section 24, so can be with the optical axis direction height of the bending part 17 after the bending wide cut W as linearity section 24, so the height of the optical axis direction after the bending can be reduced.For this reason, can with the optical axis direction of lens driver 1 keep lowlyer, can prevent the plastic deformation of wrist 15.
In addition, as shown in Figure 5, bending line 16 be arranged on by in start portion 201 and end of a period section 202 positions, be adjacent on arc sections 22 positions 160.So, also can be arranged on than arc sections 22 further from position 162 on.In addition, in Fig. 3 to Fig. 5, bending line 16 shows is that the distance of the shortest connection is connected in start portion 201 with end of a period section, but also can unnecessary the sort of bee-line on position 163 connect, and tilts to connect also to have no relations.
