Fig. 2 shows zoom lens of the present invention in situation when receiving of retracting.
On the support that Fig. 3 shows zoom lens of the present invention, each assembly is in the situation of stowing operation.
The situation that the moving part that Fig. 4 shows zoom lens of the present invention not yet drives focusing mirror group to rotate.
The situation that the moving part that Fig. 5 shows zoom lens of the present invention drives focusing mirror group to rotate.
Fig. 6 is the schematic diagram focusing mirror group of Fig. 3, inside casing, housing and moving part removed.
Embodiment
Refer to Fig. 1, in the present embodiment, zoom lens 10 comprises a plurality of varifocal mirror group 40,42 and focusing mirror group 44, in time taking, varifocal mirror group 40,42 can move along optical axis OA by zoom motor 30 (being shown in Fig. 3) drives, to carry out zoom operation, and the mirror group 44 that focuses can move along optical axis OA by focusing motor (not shown) drives, to carry out focus operation.
When not taking, zoom lens 10 retracts to carry out stowing operation, and now varifocal mirror group 40,42 and focusing mirror group 44 all can move along optical axis OA, then the mirror group 44 that focuses can rotate according to direction of arrow B, to abdicate space, for rear to varifocal mirror group 40,42 enter stop, result is as shown in Figure 2.Arrangement space by this, can reach the object of zoom lens 10 slimming.
Refer to Fig. 3, focusing mirror group 44 is fixedly arranged in inside casing 45, inside casing 45 is then rotatably be arranged in housing 46, when doing to rotate avoidance action, focusing mirror group 44 and inside casing 45 rotate together, and housing 46 does not and then rotate, Fig. 4 and Fig. 5 shows focusing mirror group 44 and inside casing 45 together along the situation that direction of arrow B rotates.
Inside casing 45 is provided with lug 451, and correspondence is provided with groove 461 on housing 46, before inside casing 45 does not rotate according to direction of arrow B, lug 451 rests in groove 461, the present invention utilizes torsion spring 47 to rest against housing 46 and inside casing 45 in addition simultaneously, and inside casing 45 can be made to remain positioned in housing 46, until under the pushing of aftermentioned moving part 34, overcome the acting force of torsion spring 47, inside casing 45 can be made to produce and rotate.
Action is avoided in the rotation of focusing mirror group 44 of the present invention, utilizes zoom motor 30 to drive, but not focusing motor (not shown).In detail, on support 20, zoom motor 30 outputting power, drives the second transmission gear (such as ring gear RingGear) 33 to rotate via zoom gear system 31, first transmission gear (such as spool gear SpoolGear) 32.As shown in Figures 4 and 5, second transmission gear 33 rotates along direction of arrow C, its inner rim teat 331 is utilized to promote the moving part 34 of L-type, the extension 452 of inside casing 45 is pushed again by moving part 34, thus make focusing mirror group 44 and inside casing 45 rotate together along direction of arrow B, reach the object of aforementioned avoidance varifocal mirror group 40,42.
The moving part 34 of L-type is rotatably arranged on support 20.Refer to Fig. 6, Fig. 6 is the schematic diagram focusing mirror group 44 of Fig. 3, inside casing 45, housing 46 and moving part 34 removed.As shown in the figure, the below of moving part 34 is provided with torsion spring 22, torsion spring 22 is resisted against support 20 inwall and the protruding bottom (not shown) of moving part 34 simultaneously, when moving part 34 is pushed by the inner edge teat 331 of the second transmission gear 33 and rotates, pressurized is out of shape by torsion spring 22, when the inner edge teat 331 of the second transmission gear 33 leaves moving part 34, the restoring force of torsion spring 22 can make moving part 34 get back to original position.
The invention provides a kind of zoom lens, action is avoided in the rotation of its focusing mirror group, utilizes zoom motor to drive, but not focusing motor, and by whole mechanism again planning and design, to provide the scope of application widely.
Although above illustrated embodiment drives focusing mirror group to carry out rotation with zoom motor avoid action, but can recognize, the mechanism utilizing other motor any to coordinate the present invention to redesign drives focusing mirror group to carry out rotation avoidance action, also should belong to category of the present invention.
Although the present invention discloses as above with preferred embodiment; but it is also not used to limit the present invention, those skilled in the art person, without departing from the spirit and scope of the present invention; still can do a little change and retouching, therefore protection scope of the present invention is when being as the criterion depending on the claim person of defining.
