Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing, the present invention being done to one specifically introduces.
Referring to Fig. 1, is the embodiment schematic diagram of optical anti-shake drives structure of the present invention.Described drives structure 10, it comprises a pedestal 12, sliding platform 14, drive unit 16 and a restraint device 18.The middle position of described pedestal 12 has a light hole 122, and described light hole 122 runs through described pedestal 12, allows that light enters or penetrate described light hole 122.When described pedestal 12 is arranged between camera lens and image sensor (not indicating in figure), the hole that described light hole 122 passes through for camera lens optical axis.At least two guide rods 124 are set on described pedestal 12, the same plane layout of described guide rod 124 on described pedestal 12, the plane at described guide rod 124 places is mutually vertical with the light that described light hole 122 passes through.In present embodiment, two guide rods 124 are set on described pedestal 12, described two guide rods 124 lay respectively at two axial locations of same plane.Described two guide rods 124 arrange by the bearing seat 126 having on described pedestal 12, and described bearing seat 126, in the two end supports of described guide rod 124, all maintains in same plane described guide rod 124.Described guide rod 124 is supported and is positioned on the surface of described pedestal 12 by described bearing seat 126, makes to have Yi Ge space 120 between described guide rod 124 and described pedestal 12 surfaces, and described space 120 highly allows that described sliding platform 14 arranges.On described sliding platform 14, there is a hole 142, in described hole 142, having lens (not indicating in figure) arranges, described hole 142 is relative with the described light hole 122 of described pedestal 12, and the light that described light hole 122 passes through can be projected via the lens in described hole 142.
Described sliding platform 14 includes first plane 144 and second plane 146, and described the first plane 144 is towards the surface of described pedestal 12, and described the second plane 146 is positioned at the described first plane 144 back side.In described the second plane 146, relatively described guide rod 124 position has at least three hooks 1462 settings, described hook 1462 is upright in described the second plane 146, between the hook end of described hook 1462 and described the second plane 146, have a spacing 1460, the width of described spacing 1460 allows that described guide rod 124 arranges.Described hook 1462 respectively hooks, on described guide rod 124, hangs on the surface of described pedestal 12 (as shown in Figure 2) described sliding platform 14.Described hook 1462 is along described guide rod 124 slippages, make described sliding platform 14 can the same plane on described pedestal 12 carry out different directions and move, thereby the described hole 142 interior lens relative with described light hole 122 can be done the adjustment of relative position.In other words, the lens of described hole 142 interior settings are along with the adjustment of described sliding platform 14 positions, can guide the adjustment of light that described light hole 122 penetrates light shaft offset while carrying out hand shake.The hook end of described hook 1462 is dihedral cylinder, and locate hooking on the cylinder body of rod of described guide rod 124 with the angle that connects of described dihedral cylinder, can reduce the friction of surface of contact between described hook 1462 and described guide rod 124, make the slippage of described sliding platform 14 more smooth and easy.In present embodiment, the hook end of described hook 1462 is triangle prism, and connects angle hooking on described guide rod 124 with one of them.
The slippage of described sliding platform 14 is to be driven by described drive unit 16, and described drive unit 16 is arranged on described pedestal 12, and between described pedestal 12 surfaces and described first plane 144 of described sliding platform 14.Described drive unit 16 comprises at least two coils 162, at least two magnet 164 and at least two hall sensors (Hall sensor) 166, it is upper that described coil 162 and described hall sensor 166 are arranged at described pedestal 12 surfaces, and described magnet 164 is arranged in described the first plane 144 (as shown in Figure 3).When described sliding platform 14 hangs on described guide rod 124, described the first plane 144 is relative with described pedestal 12 surfaces, and 164 of described magnet are relative with described coil 162 and described hall sensor 166.Described magnet 164 is relative with described coil 162, produces the strength of driving by magnetic action therebetween, and described driving force acts on described sliding platform 14 and makes it produce the running of displacement.Described magnet 164 is relative with described hall sensor 166, described hall sensor 166 by the sensing of described magnet 164 magnetic flux to detect the displacement of described sliding platform 14.Described hall sensor 166 is by the displacement of described sliding platform 14, the control disposal system that is fed back to anti-hand shake (does not indicate in figure, that it will not go into details for conventional devices), make described control disposal system can effectively adjust the adjustment of described sliding platform 14 the above lens on light axle offset.
In present embodiment, described two guide rods 124 that described drive unit 16 correspondences arrange on described pedestal 12 surfaces, use two coils 162, two magnet 164 and two hall sensors 166.The relatively described guide rod 124 of a described coil 162, a described magnet 164 and a described hall sensor 166 arranges, make described two guide rods 124 there is separately axial driven unit, to drive the slippage under the guiding of described two guide rods 124 of described sliding platform 14.The displacement of described sliding platform 14 optical axis deviation that mainly hand-held vibrations produce when taking image, therefore need in causing the scope of optical axis deviation, described hand-held vibrations control the displacement of described sliding platform 14, if exceed sliding platform 14 described in this scope, cannot be controlled and be lost efficacy, so described sliding platform 14 needs described restraint device 18 to limit the scope of its displacement in the scope of hand-held inclined to one side shake.Described restraint device 18 comprises a reference column 182 and a pilot hole 184.Described reference column 182 is arranged on the surface of described pedestal 12, and described pilot hole 184 is arranged on described sliding platform 14, and described reference column 182 is positioned at described pilot hole 184.When described sliding platform 14 hangs on described guide rod 124, described reference column 182 is fixed in the lip-deep position of described pedestal 12, described sliding platform 14 will be limited in the scope intrinsic displacement of hole by described pilot hole 184, produce the restriction to described sliding platform 14 displacement activity scopes.The relatively described guide rod of shape 124 positions of described pilot hole 184 holes shaping (as shown in Figure 1) is set, effectively to limit the displacement range of described sliding platform 14.In present embodiment, it is rectangle that the position that described two guide rods 124 arrange makes the void shape of described pilot hole 184.
Optical anti-shake drives structure of the present invention, described guide rod 124 with same plane layout on described pedestal 12 hangs described sliding platform 14, and at described pedestal 12, described drive unit 16 and described restraint device 18 are set, can drive and limit described sliding platform 14 at the scope intrinsic displacement of hand-held vibrations, the light shaft offset causing with opponent's shake is adjusted.Described drives structure is used member simplification, reducing thickness, is made assembling easily, and the cumulative limit that can reduce again manufacture has preferably effective utilization.
In addition, those skilled in the art also can do other and change in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
