Fig. 8 A shows the schematic top plan view of ring-type whirligig 420.Show on the figure that three jut 420A are 120 degree and distribute.Another surface of ring-type whirligig 420 shown in Fig. 8 B, has one second outer ring 421, the second inner ring 422A, the 3rd an inner ring 422B and one the 4th an inner ring 422C.The 4th inner ring 422C is in order to place annular gasket 414.The second inner ring 422A is in order to place spring 410.Second outer ring 421 comprises one first part, 423 and one second portion 424.Wherein first part 423 has gear, with engagement rotation driving-disc 418, and has one the 3rd jut 424A on the second portion 424, so that ring-type whirligig 420 only limits to the scope rotation at the first breach 429B.The center of ring-type whirligig 420 has a plurality of box threads, so that lens group 402 turn up and down in the 4th inner ring 422C.The 3rd inner ring 422B continues turn in the 4th inner ring 422C in order to stop lens group 402.The first handle shape part 427 is connected with the second breach 429C, and has a right cylinder 427A on the first handle shape part 427, with connection gear than changeover panel 418.The box thread of ring-type whirligig 420 can allow an end have lens group 402, precession or the back-out of male thread 402A.
Fig. 9 shows the front elevational schematic of gear than changeover panel 418.Gear is than having a hole 418B, with the right cylinder 427A on the first handle shape part 427 that connects pedestal 426 on the changeover panel 418.Please be simultaneously again with reference to figure 8B, gear can be connected with second outer ring 421 of ring-type whirligig 420 than the gear parts 418A of changeover panel 418 is feasible via 419 driven gears of the gear on the servo motor than changeover panel 418, first 423 with second outer ring 421 of engagement ring-type whirligig 420, make ring-type whirligig 420 and gear than changeover panel 418 interlocks, so that lens group 402 is mobile on plane, vertical first groove, 431 place, to adjust the focal position of lens group 402.
The schematic top plan view of Figure 10 A display base 426.Pedestal 426 comprises one first a handle shape part 427 and a column part 428.One end of column part 428 has one first groove 431, and the other end has one second groove 432, and wherein first groove 431 is in order to carrying ring-type whirligig 420, and second groove 432 is in order to carrying image capture element 438.In addition, column part 428 one first inner ring 430 that comprises one first outer ring 429 that is positioned at first groove, 431 outsides and be positioned at first groove, 431 bottoms.Have a plurality of first jut 429A on the outside of first outer ring 429, in order to connect lid 406.According among the embodiment of the present utility model, the number of the first jut 429A is three.Comprise one first breach 429B and one second breach 429C on first outer ring 429 again.Wherein the first breach 429B uses so that the 3rd jut 424A of ring-type whirligig 420 can be in the scope rotation of the first breach 429B.The second breach 429C uses so that ring-type whirligig 420 is connected than changeover panel 418 with gear through the second breach 429C.
Still please refer on first inner ring 430 in Figure 10 A lens assembly 302 and comprise first inner ring 430 that a plurality of inclined-planes group is surrounded, this a plurality of inclined-planes group is divided this first inner ring 430 equally, with a preferred embodiment, three inclined-plane groups can reach the functional requirement of stepless focusing of the present utility model.It should be noted that each inclined-plane group comprises main inclined plane sign and indicates with 430B with a 430A and a secondary inclined-plane, the maximum arc length that the maximum arc length on secondary inclined-plane is far smaller than main inclined plane gets final product, and both are connected.And the degree of tilt of all main inclined planes is identical, and equal in length, and the most significant digit standard of each main inclined plane is contour, and the lowest order standard of each main inclined plane is also contour.Lowest order standard to the height of most significant digit standard is about 0.1～0.6mm.The height change of general 0.2～0.4mm promptly has been enough to deal with the situation of generally taking pictures.Have only special close-perspective recording or far away the bat just to use this scope difference in height in addition.The main inclined plane that any two adjacent inclined-plane groups are comprised is connected with a secondary inclined-plane.Certainly, on this alleged secondary inclined-plane also can be a vertical plane, for example among Figure 10 A, the main inclined plane 430A of the main inclined plane 430A of the first inclined-plane group and the adjacent second inclined-plane group is connected mutually with secondary inclined-plane 430B (can be vertical plane), when gear rotated on first inner ring 430 than changeover panel 418 drive ring-type whirligigs 420, the position of three second jut 420A of ring-type whirligig 420 (please also refer to Fig. 8 B) can change on each the main inclined plane 430A on first inner ring 430.Because three main inclined plane 430A are inclined-planes, therefore, ring-type whirligig 420 can be on the continually varying inclined-plane.The pitch angle on inclined-plane is bigger, and the scope of adjustment also will heal greatly.This will make lens group 402 move on plane, vertical first groove, 431 place, therefore be adjusted the focal position of lens group 402.
It should be noted that, the above-mentioned first breach 429B the 3rd jut 424A and non-essential design are because ring-type whirligig 420 also can be at the rotation of making whole circle on the inclined-plane of the pedestal group and three outshot 420A that the keep ring-type whirligig 420 accurate height in same position on three main inclined plane 430A still.
Generally speaking, be that gear 419 driven gears by servo motor (not shown) make the plane of ring-type whirligig 420 move on the slope of main inclined plane 430A than changeover panel 418 when automatic focusing, when the length of each main inclined plane 430A of each angle correspondence of servo motor (not shown) more hour, expression can be focused meticulousr.But the time of relative automatic focusing also can be longer.
Figure 10 B is the bottom schematic view of display base 426 then.The bottom of pedestal 426 can be an image capture element 438 in order to be connected as shown in figure 11, in order to changing electric signal into by the light signal of lens group 402.Figure 12 and shown in Figure 13 be respectively aluminium flake 434 and insulcrete 442.Both have at the hole of same position 434A in order to be connected with screw with pedestal 426.In addition, and two rectangle cavities are arranged in order to angle (pin) part of connecing of image capture element 438 is exposed aluminium flake 434 outside insulcrete 424.
The lens assembly 302 that utilizes the utility model to propose with the digital camera that does not have the section focus function, can absorb the scenery of different distance, solved the lens assembly 102 of conventional digital camera, because only have single focal length function, thereby can't clearly absorb the problem of hypotelorism or scenery far away excessively.In addition, because the lens assembly 302 with the digital camera that does not have the section focus function that the utility model proposed is to utilize rotation ring-type whirligig 420, to adjust the focal position of lens group 402.This kind adjusted the method for the focal position of lens group 402, can't produce the power of Vertical camera lens group 402 moving directions, so lens group 402 can not produce skew on the direction that Vertical camera lens group 402 moves.
The utility model with the preferred embodiment explanation as above, is not in order to limit application range of the present utility model only.
