Embodiment
Fig. 1 to Fig. 4 has shown an embodiment of the present utility model, many Zoom Lens device that motor configuration comprises an autofocus motor and is arranged on autofocus motor yoke end in this embodiment.
The model of autofocus motor can be selected as required, such as common autofocus motor, open loop type, closed loop or with multiaxial type motor of optics anti-trembling function etc.In the present embodiment, autofocus motor comprises and is arranged on the focusing coil 2 of lens mount 1 one end, four blocks of second magnetites 3, a spring leaf 4, the shell being comprised of metal yoke 5 and bottom 6, the assembly of pin, and camera lens is coaxial and be parallel to optical axis with lens mount 1.The outer race of lens mount 1 has a pair of focal line circle 2, is used for realizing lens focusing.The inwall of yoke 5 is provided with and four altogether of interactional the second magnetite 3, the second magnetites 3 of the coil 2 of focusing, is distributed on four inwalls of yoke 5, and parallel with four limits of focusing coil 2, the second magnetite 3 is the S utmost point towards the one side of focusing coil 2.Spring leaf 4 comprises housing, inner ring and the elastic strip that connects outer ring and inner ring, and the housing of spring leaf is fixed by magnetite and bottom, and the inner ring of spring leaf is fixedly connected with the end face of lens mount, can accurately control the amount of movement of camera lens by spring leaf.When the energising of focusing coil 2, the second 3 pairs of magnetites lens mount 1 produces the acting force of a parallel optical axis, makes lens mount 1 prolong optical axis direction and moves forward and backward and realize automatic focusing function.
Many Zoom Lens device is arranged on the upper surface of above-mentioned autofocus motor yoke end, comprise be arranged on yoke end face translation coil groups 7, the support 8 being flexibly connected with translation coil groups, be fixed on magnetite group and lens combination on support 8, translation coil groups 7 interacts with magnetite group, controls support 8 and in the plane that is parallel to translation coil groups, carries out many axially-movables.
Wherein, translation coil groups comprises at least 2 translation FPC coils 9, in the present embodiment, translation FPC coil 9 is evenly provided with four translation FPC coils along four edges of yoke 5 end faces, and the line alignment of each translation FPC coil is consistent, be clockwise coiling, be counterclockwise coiling, two relative translation FPC coils can be connected, the FPC coil that the utility model adopts can substitute existing copper coil completely, copper coil manufacture craft difficulty is very large, need to assist automatic winding equipment and mold, the dimensional accuracy of production efficiency and yield and coil is relatively low, and FPC coil adopts very ripe flexible circuit board manufacture craft at present, precision is high, yield is high, production efficiency is also high, simplified greatly the production technology of coil, reduced cost.
The plane parallel at magnetite group and coil groups place, comprise and being arranged on support 8 and 9 interactional at least 2 blocks of first magnetites of translation FPC coil, in the present embodiment, on support, the position relative with translation FPC coil is also provided with four blocks of first magnetites 11, four blocks of first magnetites 11 all adopt plane the two poles of the earth note magnetic, and the opposite side polarity of two blocks of relative first magnetites is contrary.Lens combination is arranged on bracket end face central authorities, by the first magnetite, surrounded, lens combination need to evenly arrange at least two lens 10 for amplifying, in the present embodiment, four lens 10 have been adopted, and be arranged in array, always, and the enlargement factor between them is all not identical for the radius of these four lens.Support 8 can be connected with metal yoke by suspension spring or ball.
When translation FPC coil electricity, due to magnet side magnetic fields, can produce an acting force that is parallel to translation FPC coil place plane to the first magnetite, this acting force is perpendicular to the optical axis of above-mentioned autofocus motor, make optical lens that the first magnetite drives support and a plurality of same diameters planar carry out many axially-movables being parallel to translation coil groups, when radius that the amount of movement of support is optical lens, the optical lens of different multiples (increasing times mirror) is switched at the camera lens optical axis center that can realize automatic focusing, thereby realizes the many Zoom Lens of discrete.When support carries out small size translation on the basis of above-mentioned amount of movement (amount of movement is less than the radius of lens), can realize same optical lens moving relative to autofocus lens optical axis center, realize the small size translation of image, be enough to compensate hand and tremble the image causing and move, thereby realize the anti-shake function of optics.
In addition, in the plane at coil groups place, also can be placed with the Hall element that is respectively used to Bracket for Inspection horizontal stroke, lengthwise movement.Can accurately measure lens combination and the support horizontal level in two dimensions, realize closed-loop control, make the position control of lens reach the most accurate.
Although it is pointed out that the utility model cannot realize optics continuous vari-focus, can realize the continuously harmless zoom that surpasses 10 times in conjunction with the harmless zoom of electronics.The utility model passes through autofocus motor, the assembly of translation FPC coil and the first magnetite, can realize automatic focusing, optical zoom and the optics anti-trembling function of camera lens, Qie Gai mechanism is simple, volume is little, module height can be controlled in 6 millimeters, conforms with the thickness requirement of current main flow smart mobile phone, therefore has high marketable value.
