Detailed description of the invention
Fig. 2 is the schematic diagram of the lens adjusting apparatus of the present invention, and Fig. 3 is cutting of the lens adjusting apparatus of the present invention
Face schematic diagram, Fig. 4 is the schematic diagram of the movable plate second of the present invention, refer to Fig. 2 to Fig. 4.
Lens adjusting apparatus is in order to the movement of camera lens 250, including base 210, movable plate the 220, first motor
231, gear 232.Movable plate 220 has the first relative face 2201 and the second face 2202, and camera lens 250 is solid
On the first face 2201 of movable plate 220, the second face 2202 of movable plate 220 is movably connected to base
On 210.Second face 2202 of movable plate 220 is provided with tooth bar 221, and tooth bar 221 has plurality of parallel contour
And the dentalation arranged continuously.First motor 231 is fixed on base 210.Gear 232 couples the first motor
231, and gear 232 coordinates with tooth bar 221, the first motor 231 controls pinion rotation 232 so that tooth bar 221
Opposed gear 232 moves, thus drives the movement on movable plate 220 C in a first direction.
Wherein, the tooth bar 221 extended line on this first direction C 2211 is vertical and intersects at the center of gravity of camera lens 250
To the vertical line of movable plate 220, intersection point is 251.I.e. the direction of tooth bar 221 is through " center of gravity " of camera lens, thus
Do not have the most smooth mobile shortcoming.
In the present embodiment, lens adjusting apparatus also includes the second motor 241, slide block 222, screw rod 242.The
Two motor 241 is fixed on base 210；Slide block 222 is arranged on movable plate 220, and slide block 222 has interior spiral shell
Stricture of vagina.In the present embodiment, slide block 222 is arranged on shifting by the way of the sliding groove structure 225 on engaging movable plate 220
On dynamic plate 220, in other embodiments, slide block 222 also can be one-body molded with movable plate 220, or uses it
He fixes at fixed form, such as screw locking etc., only need to meet slide block 222 and not occur relative with movable plate 220
Displacement.
Screw rod 242 D in a second direction is arranged, and screw rod 242 couples the second motor 241 and has external screw thread, and spiral shell
The external screw thread of bar 242 and the screw-internal thread fit of slide block 222, the second motor 241 controls screw rod 242 and rotates so that
Slide block 222 moves relative to screw rod 242, thus drives the movable plate 220 movement in second direction D, second party
It is different from this first direction C to D.
In the present embodiment, second direction D is perpendicular to first direction C.
In the present embodiment, the second face 2202 of movable plate 220 is movably connected to the connection on base 210
Mode is not construed as limiting.Such as, if only needing to move in one direction, the second face 2202 can be provided with
Second slide block (not shown), base is offered chute (not shown), and the second slide block can slide in chute, sliding
The glide direction of groove is parallel to first direction C, and so, tooth bar 221 opposed gear 232 moves, and can drive shifting
Move on dynamic plate 220 C in a first direction.The most such as, if need to move in two different directions,
Second face 2202 of movable plate 220 can be arranged runs through protruding 223, and base 210 has mobile bar 211, mobile
Bar 211 can move in base 210 in second direction D, and running through protruding 223, be sheathed on after mobile bar 211 can be
Move on first direction C.Certainly, in other embodiments, the second face 2202 of movable plate 220 is moveable
The mode being connected on base 210 is alternatively other modes, only need to disclosure satisfy that movable plate 220 can be in base 210
Upper freely adjust.
As in figure 2 it is shown, in the present embodiment, the first motor 231 is positioned at the phase of base 210 with the second motor 241
To both sides.Such as, it is arranged on the relatively short opposite sides of lens adjusting apparatus, permissible after so arranging
Reduce the space of waste when motor is placed, reach to reduce the effect of lens adjusting apparatus volume.
For reducing the volume of lens adjusting apparatus further, tooth bar 221 is protruded from movable plate by the present embodiment
The design in 220 second faces 2202, then make the first motor 231 be perpendicular to first direction with the orientation of gear 232
C。
In the present embodiment, as shown in Figure 4, movable plate 220 also has opening 224.Opening 224 and lens 250
Corresponding.And tooth bar 221 extends to opening 224, the volume minimization of movable plate so can be made.
The lens adjusting apparatus of above-mentioned all embodiments all can be used on scialyscope, in order to moving lens, and then
By the projection of scialyscope to correct region.
In sum, the tooth bar direction of the lens adjusting apparatus of the present invention, through " center of gravity " of camera lens, can make
The adjustment of camera lens is more smooth and easy.Further, by two motors being arranged on the opposite sides of movable plate,
The volume of lens adjusting apparatus can be reduced.
Certainly, the present invention also can have other various embodiments, without departing substantially from present invention spirit and the feelings of essence thereof
Under condition, those of ordinary skill in the art can make various corresponding change and deformation according to the present invention, but this
A little corresponding changes and deformation all should belong to the protection domain of appended claims of the invention.
