Embodiment
Following content describes the 1st embodiment of the present invention in detail with reference to Fig. 1～Fig. 5.Drive unit 1 about present embodiment is the lens driver that a kind of automatic focusing that is assembled in the mobile phone is taken a picture.
The configuration of this lens driver 1 is, as shown in Figure 1, has the base 8 and the rear side spring 11 that are provided with on the framework 7 that is provided with on the collar extension 3, lens carrier 5, collar extension 3 optical axis direction front sides of ring-type and front side spring 9, collar extension 3 rear sides.Be configured in the pad (insulating material) 15 between rear side spring 11 and the collar extension 3.On the periphery of lens carrier 5, be fixed with coil case 4.
As shown in Figures 1 and 2, collar extension 3 sees that from the front side periphery wall 3a slightly is quadrangle, and four jiaos bight 3b is chamfer shape.As shown in Figure 1,, on periphery wall 3a, be formed with the patchhole 21 that the 2nd magnetite 18 inserts, the 2nd magnetite 18 inserted interior all sides of collar extension 3 from outer circumferential side at each bight 3b of collar extension 3.
Going up in week to add up in the periphery wall 3a of collar extension 3 has 8 the 1st magnetites 17, and is fixed with the 2nd magnetite 18 of 4 of the totals that are being provided with respectively on the bight 3b of collar extension 3.
Each the 1st magnetite 17, as shown in Figures 1 and 2, see plane formation slightly triangular in shape from each front side, its thickness of 3b place, bight of past more collar extension 3 is thick more, interior all sides are to constitute along the circular arc shaped on the 1st annulus 19 (there the is narration the back) outer peripheral face, and the 1st magnetite 17 that collar extension 3 bight 3b adjoin is to be configured on the interval location of mutual appointment.In addition, magnetic pole is also different on interior all sides of the 1st magnetite 17 and the outer circumferential side, such as being the N utmost point on interior all sides, is the S utmost point so on the outer circumferential side.
The 1st magnetite 17 is one group with adjacent each other any 2 magnetites 17,17, adds up to 4 groups magnetite portion, 4 groups magnetite portion on the peripheral direction of the 1st annulus 19 (there is narration the back) with uniformly-spaced the configuration.
Among 4 of collar extension 3 each bight 3b, be fixed with each the 2nd magnetite 18 on the inner peripheral surface of the periphery wall 3a of collar extension 3.As shown in Figure 2, the 2nd magnetite 18 and is separated with the gap between the 1st magnetite 17 and disposes between the 1st adjacent magnetite 17,17.The 2nd magnetite 18, all sides have different magnetic poles with outer circumferential side in it.In the present embodiment, interior all sides are the N utmost point, and outer circumferential side is the S utmost point.In addition, in the present embodiment, the magnetic pole of interior all sides of the 2nd magnetite 18 is identical with the magnetic pole of adjacent the 1st magnetite 17, and magnetic flux and the 1st annulus 19 are the orthogonal shape.
As shown in Figure 1, it is cylindric that lens carrier 5 slightly is, and is fixed with lens (explanation of not mapping) on its interior all sides.Fixing coil 4 is made up of the 1st annulus 19 and the 2nd annulus 16a, 16b, 16c, 16d on the periphery of lens carrier 5.
The 1st annulus 19 constitutes circular along lens carrier 5 circumferentially full phase volume commentaries on classics.The 1st annulus 19 all is banded, its outer peripheral face and the 1st magnetite 17 opposite faces.
On the 1st annulus 19 peripheries, uniformly-spaced (90 intervals) locate to be provided with 4 the 2nd annulus 16a, 16b, 16c, 16d on circumferentially.(from the periphery of the 1st annulus 19 always) slightly is quadrangle respectively from its side for each the 2nd annulus 16a～16d, constitutes to be slightly that the coil volume changes into shape on the dimetric ring direction.As shown in Figure 2, the ring inboard of summary 4 dihedrals of each the 2nd annulus 16a～16d disposes the 2nd magnetite 18.
The 2nd annulus 16a, 16c are from 180 degree, because the magnetic force of wiring direction from the slightly cylindric side of the 2nd magnetite 18 respectively, and the electric current that passes through of the 2nd annulus 16a, 16c, according to the Fleming, John Ambrose left-hand rule, the radial direction of lens carrier 5 will be subjected to the effect of a thrust E.Equally, the 2nd annulus 16b, 16d, because the magnetic force of wiring direction from the slightly cylindric side of the 2nd magnetite 18 respectively, and the electric current that passes through of the 2nd annulus 16b, 16d, thrust F will act on.
The direction of thrust E is the direction that the 2nd annulus 16a links to each other with the 2nd annulus 16c.The direction of thrust F is the direction that the 2nd annulus 16b links to each other with the 2nd annulus 16d.Thrust E and the mutual orthogonal of thrust F.
As shown in Figure 4, the 1st annulus 19 and Z drive division 32 mutually in succession, each the 2nd annulus 16a～16d is connected with X-Y drive division 33, can pass to the electric current of certain value from each drive division 32,33.
In addition, in the present embodiment, the 2nd annulus 16a and 16c, 16b and 16d are in series, in the thrust E direction of two annulus 16a and 16c, and drive on the thrust F of 16b and 16d direction.
For example, Z drive division 32, when lens carrier 5 moves toward focusing position (optical axis direction moves), galvanization Z on the 1st annulus 19.
Equally, during anti-shake revisal, X-Y drive division 33 is gone up galvanization E toward the 2nd annulus 16a and 16c, and lens carrier 5 is moved on the E direction, toward the last galvanization F of the 2nd annulus 16b and 16d, makes lens carrier 5 mobile on the F direction.According to this, lens carrier moves on the E-F direction carries out anti-shake revisal.
What in addition, the Z of Fig. 4, E, F symbol were illustrated is thrust direction that electric current produced and the size that is flowed.
But as shown in Figure 2, in the form of this enforcement, directions X is an edge direction that slightly is dimetric collar extension 3, and the Y direction is the adjacent edge direction of slightly tetragonal collar extension 3.The thrust E, the F that are produced about collar extension 3 diagonals, the component EX of directions X and FX sum are as the expulsive force of directions X, the component EY of Y direction and FY sum are as the expulsive force of Y direction, so X-Y drive division 33, the component sum EX+FX of each directions X is as the directions X driving force, and the component sum EY+FY of each Y direction controls as Y direction driving force.
As shown in Figure 1, front side spring 9, state of nature before installing is a tabular, is to be made of 4 wrist 9c that all sidepiece 9b, periphery sidepiece 9a and interior all sidepiece 9b in the plane circular arc that upward is provided with in week in the periphery sidepiece 9a, the peripheral part 9a that constitute plane quadrangle ring-type are connected.The deformation energy that makes Z direction and X-Y direction arbitrarily freely.
Rear side spring 11, be that state of nature is a tabular before the installation, be by the periphery sidepiece 11a that constitutes plane quadrangle ring-type, 4 wrist 11c that interior perimembranous 11b, the periphery sidepiece 11a of the plane circular arc that is disposed on the interior week of periphery sidepiece 11a and interior all sidepiece 11b are connected constitute, and the deformation energy that makes Z direction and X-Y direction arbitrarily freely.
In addition, front side spring 9 periphery sidepiece 9a be seize on both sides by the arms between framework 7 and collar extension 3, interior all sidepiece 9b are the front ends that is fixed on lens carrier 5.The periphery sidepiece 11a of rear side spring 11 seizes on both sides by the arms between base 8 and rear side pad 15, and interior all sidepiece 11b are fixed on lens carrier 5 rear ends.With this, rely on front side spring 9 and rear side spring 11, support of lens carrier 5 past optical axis sides' (Z direction) and X-Y direction move freely.
Then, in case lens carrier 5 moves toward optical axis direction the place ahead, front side spring 9 and rear side spring 11 fore-and-aft direction precompressions make a concerted effort and the 1st annulus 19 and the 1st magnetite 17 between produced electromagnetic force phase equilibrium locations the time, lens carrier 5 will stop to move.
When lens carrier 5 moved toward the X-Y directions, the spring of the X-Y direction of front side spring 9 and rear side spring 11 made a concerted effort, with each corresponding the 2nd magnetite 18 of the 2nd annulus 16a～16d between the electromagnetic force that produced stop during equilibrium locations mutually.
Next, assembling, effect and the effect to the relevant lens driver 1 of the embodiment of the invention describes.Before lens driver 1 assembling, each the 2nd annulus 16a～16d then to be fixed on the outer peripheral face of the 1st annulus 19 earlier, form coil case 4 in advance.Lens driver 1 assembling, as shown in Figure 1, on base 8, fixed the collar extension 3 of each the 1st magnetite 17 on the lens carrier 5 of rear side spring 11, rear side pad 15, periphery upper fixed line circle body 4, the interior all sides, front side spring 9, and framework 7, order is assembled fixing successively according to this.
Then, after assembling is finished, the 2nd magnetite 18 is inserted into inserting in the hole that each bight 3b of collar extension 3 forms from interior all sides of collar extension 3.Subring oralia 25 then is fixed on the periphery wall 3a.
Next, as shown in Figure 4, the 1st annulus 19 will connect the input end and the output terminal of electric current on the Z drive division 32, the 2nd annulus 16a～16d the coil 16a of subtend and 16c, 16b with after 16d connects, the input end and the output terminal of each electric current of connection in the X-Y driving 33.
The driving of the lens driver 1 of relevant present embodiment, as Fig. 4, Z drive division 32 is after comparing one by one from the peak value that portrait (imaging) sensor 31 receives the high-frequency composition (contrast) that comes, lens supports body 5 to be moved to closing the straight line that carries out the Z direction in the focal position.
When the Z of lens supports body 5 direction moves as straight line, the electromagnetic force that is produced between current value Z on the 1st annulus 19 and the magnetite 17, with the precompression of front side spring 9 and rear side spring 11 make a concerted effort reach the equilibrium locations point and will stop.
In addition, the X-Y control (anti-shake revisal) of lens carrier 5, accept the size of the anti-shake revisal amount of directions X and Y direction as signal according to Gyro Assembly etc., the anti-shake revisal amount of calculating directions X and Y direction decides amount of movement E, the F of the 2nd annulus, switches on toward the 2nd annulus 16a, 16c and the 2nd annulus 16b, 16d then.
In addition, as shown in Figure 2, the 2nd annulus 16a～16d, the electromagnetic force according to right edge portion 24 and back, left side portion 26 are acted on makes the thrust that produces E, F direction on the lens carrier 5.
According to present embodiment, as mentioned above, can realize mobile (toward moving of Z direction) of lens carrier 5 focusings and anti-shake revisal (toward moving of X-Y direction).
On the periphery of lens carrier 5 week of configuration the 1st annulus 19, the 1 annuluses 19 upwards configuration wait every the 2nd annulus 16a～16d, collar extension 3 on only be provided with each annulus 19, with the magnetite 17,18 of 16a～16d opposite face.Therefore, can realize miniaturization by simple structure.
Because of the 2nd magnetite 18 is the inboards that are configured in the 2nd annulus 16a～16d ring, it is littler that the radial space of lens carrier just can become, and realize small-sized structure.
The 2nd magnetite 18 inserts interior all sides of fixedly advancing collar extension 3 from the patchhole 21 that the periphery wall 3a of collar extension 3 forms, so assembling easily, particularly in the inboard of the ring of the 2nd annulus 16a～16d, the 2nd magnetite 18 disposes easily.
When the 2nd magnetite 18 is fixed, the patchhole 21 that forms on the collar extension 3 is stopped up, reveal, can improve the magnetic density that the 2nd magnetite is produced so can prevent magnetic flux by subring oralia 25.
As shown in Figures 1 and 2, be disposed at as the 2nd annulus 16a～16d of anti-shake revisal function and the 2nd magnetite 18 and see from the front side and to be slightly dimetric collar extension 3 bights, plane, therefore anti-shake correcting function has been arranged, and realized and do not had the same size of lens driver of the anti-shake revisal of lift-launch, and miniaturization structure.
