A screw 234, a circular arc seat 236, a sidewall 238 and a sidewall breach 239 that load bearing seat 230 is formed with a reference column groove 232, penetrates.Reference column 270 is inserted in this reference column groove 232, and reference column 270 is interspersed in the pilot hole 224 of Focusing module 220, so that Focusing module 220 relative load bearing seats 230 are when carrying out a perpendicular displacement, the position of Focusing module 220 can not be offset.Motor 280 has a motor body 282 and a rotating shaft 284, wherein motor body 282 is resisted against the circular arc seat 236 of load bearing seat 230, rotating shaft 284 is a thread spindle, and first hole 252 of motor stator 250 is passed in rotating shaft 284, and second hole 254 of motor stator 250 is in alignment with the screw 234 of load bearing seat 230, fixed screw 260 is screwed together in second hole 254 and screw 234 simultaneously, so that motor 280 is arranged at load bearing seat 230, and the axial direction level of rotating shaft 284 is in load bearing seat 230.
Sliding shoe 290 is formed with a center pit 292 that penetrates, and side is formed with a teat 294, and the position of this teat 294 is with respect to the depressed part 226 of Focusing module 220, and teat 294 is a columnar portion.Center pit 292 has the internal thread that can be screwed together in rotating shaft 284, can make sliding shoe 290 be screwed together in rotating shaft 284, and sliding shoe 290 can carry out a horizontal shift by relative load bearing seat 230 along with the rotation of rotating shaft 284.When sliding shoe 290 was screwed together in rotating shaft 284, then teat 294 was inserted and is sunk among the depressed part 226, and teat 294 conflict inclined-planes 228.
Change-over switch comprises first conductive component 242 and second conductive component 244.Wherein first conductive component 242 is arranged at load bearing seat 230, and is formed with the shape portion 243 of colluding on first conductive component 242, and this colludes shape portion 243 and colludes the sidewall breach 239 that invests load bearing seat 230.Second conductive component 244 is arranged at load bearing seat 230 equally, and when sliding shoe 290 carried out a horizontal shift and promotes second conductive component 244, then second conductive component 244 can contact first conductive component 242, represents that promptly change-over switch is triggered.
See also Fig. 3, in the preferred embodiment of the present invention about the assembling synoptic diagram of 242 of load bearing seat 230 and first conductive components.As shown in the figure, the sidewall 238 of load bearing seat 230 has a sidewall breach 239, be formed with the shape portion 243 of colluding on first conductive component 242, this colludes shape portion 243 and colludes the sidewall breach 239 that invests load bearing seat 230 so that first conductive component 244 obtains the anchorage force that this sidewall 238 is provided.Fig. 4 also is the assembly assembling synoptic diagram in the preferred embodiment of the present invention, in order to the correspondence that shows Focusing module 220, sliding shoe 290, first conductive component 242 and second conductive component 242 position is set.The teat 294 of sliding shoe 290 is corresponding to the depressed part 226 of load bearing seat 230 among the figure, and after the camera lens module assembling, teat 294 will be inserted and sink among the depressed part 226, and teat 294 conflict inclined-planes 228.First conductive component 242 and second conductive component 244 are positioned at the displacement path of sliding shoe 290, so that sliding shoe 290 when carrying out horizontal shift, is triggered change-over switch.
See also Fig. 5 and Fig. 6, be the combination schematic perspective view of a preferred embodiment of the present invention, and please cooperate Fig. 2 to read hereinafter explanation.As shown in the figure, the teat 294 that sliding shoe 290 sides form is inserted and is sunk among the depressed part 226, therefore when sliding shoe 290 carries out the horizontal shift of relative load bearing seat 230 along with the rotation of rotating shaft 284, the inclined-plane 228 of teat 294 pushing tow depressed parts 226 is so that Focusing module 220 relative load bearing seats 230 carry out perpendicular displacement.In addition, when starting the autofocus lens module at every turn, motor 280 rotating shafts 284 make sliding shoe 290 horizontal shifts to rotating shaft 284 ends, and because change-over switch is positioned at the displacement path of sliding shoe 290, therefore sliding shoe 290 can contact second conductive component 244 earlier, makes second conductive component 244 contact first conductive component 242 again.After second conductive component 244 contacted first conductive component 242, change-over switch promptly sent an electronic signal and carries out a deliberate action with control motor 280, with sliding shoe 290 horizontal shift to ad-hoc locations and be defined as initial point.
Fig. 7 A and Fig. 7 B are the side-looking diagrammatic cross-section of arrow 400 directions in the corresponding diagram 6, and please cooperate Fig. 6 to read hereinafter explanation.In order to help to understand the start relation of teat 294 and Focusing module 220, only show the relative position of Focusing module 220, load bearing seat 230 and teat 294 among Fig. 7 A.Fig. 7 A also is positioned at the synoptic diagram of initial point for teat 294 and Focusing module 220, this be since motor 280 after receiving an electronic signal, rotating shaft 284 with sliding shoe 290 horizontal shifts near an ad-hoc location of motor body 282 as the initialization setting, this moment, teat 294 was still kept the state on conflict inclined-plane 228.Fig. 7 B is the teat 294 of sliding shoe 290 and the synoptic diagram that Focusing module 220 is positioned at a specific focusing position, show among the figure that motor 280 is subjected to the driving of a governor circuit, rotating shaft 284 is with the direction horizontal shift of sliding shoe 290 courts away from motor body 282, so that the camera lens that includes in the Focusing module 220 obtains the accurately image of focusing.By among Fig. 7 B as can be known, when sliding shoe 290 carries out a horizontal shift of relative load bearing seat 230, make the inclined-plane 228 of teat 294 pushing tow Focusing modules 220, so Focusing module 220 can carry out a perpendicular displacement of relative load bearing seat 230.
The present invention utilizes above-mentioned autofocus lens module, can make horizontally disposed motor 280 cooperate sliding shoe 290 significantly to dwindle the thickness of camera lens module with the design of Focusing module 220.In addition, the shape portion of colluding 243 designs by first conductive component 242 in the change-over switch make the conductive component 242 of winning can collude the sidewall breach 239 that invests load bearing seat 230, to obtain the anchorage force that this sidewall 238 is provided.
The above is the preferred embodiment of this creation only, is not in order to limiting claim of the present invention, and therefore all other do not break away from the equivalence of being finished under the disclosed spirit and change or modify, and all should be contained in the claim of this case.
