Specific embodiment
Fig. 1 to Fig. 4 illustrates one embodiment of the present of invention, and in this embodiment motor configuration includes an auto-focusing horse
Up to and installed in many Zoom Lens devices of autofocus motor yoke end.
The model of autofocus motor can be selected as needed, such as common autofocus motor, open loop type, closed
Ring type or the multiaxial type motor with optical anti-vibration function etc..In the present embodiment, autofocus motor includes being arranged on objective carrier 1
Focusing 2, four piece of second Magnetitum 3 of coil of one end, a spring leaf 4, the shell being made up of metal yoke 5 and bottom 6, the group of pin
Part, camera lens is coaxial with objective carrier 1 and parallel to optical axis.The periphery of objective carrier 1 is cased with a pair of focal line circles 2, for realizing camera lens pair
It is burnt.The inwall of yoke 5 is provided with the second Magnetitum 3 interacted with focusing coil 2, and the second four pieces altogether of Magnetitum 3 is distributed on magnetic
On four inwalls of yoke 5 and parallel with four sides of focusing coil 2, the second Magnetitum 3 is S poles towards the one side of focusing coil 2.
Spring leaf 4 includes the elastic strip of housing, inner ring and connection outer ring and inner ring, and the housing of spring leaf is fixed by Magnetitum and bottom,
The inner ring of spring leaf is fixedly connected with the end face of objective carrier, can be with the amount of movement of precise control camera lens by spring leaf.Work as focusing
When coil 2 is powered, the second Magnetitum 3 produces the active force of a parallel optical axis to objective carrier 1, objective carrier 1 is prolonged before optical axis direction
Automatic focusing function is realized in movement afterwards.
Many Zoom Lens devices are arranged on the upper surface of above-mentioned autofocus motor yoke end, including installed in yoke
Support 8 that the translation coil group 7 of end face is flexibly connected with translation coil group, the Magnetitum group being fixed on support 8 and lens
Group, translation coil group 7 interacts with Magnetitum group, and control support 8 carries out polyaxial in the plane parallel to translation coil group
Motion.
Wherein, translating coil group includes at least 2 translation FPC coils 9, and in the present embodiment, translation FPC coils 9 are along magnetic
Four edges of the end face of yoke 5 have been uniformly arranged four translation FPC coils, and the line alignment one of each translation FPC coil
Cause, or being coiling clockwise, or being anti-clockwise windings, two relative translation FPC coils can connect, the present invention
Using FPC coils can completely substitute existing copper coil, copper coil processing technology difficulty is very big, needs auxiliary automatic
The dimensional accuracy of spooling equipment and mould, production efficiency and yield and coil is relatively low, and FPC coils are using at present very
Ripe flexible circuit board processing technology, precision is high, and yield is high, and production efficiency is also high, greatly simplify coil
