- the outer casing is composed of a bottom cover 6 and a yoke 1 in which the yoke 1 Made of metal, it can effectively isolate the internal and external magnetic fields of the shell.
- the shape of the shell is not fixed. It can be made into cylindrical, square or polygonal columns as needed.
- a lens mount 7 matching the shape thereof is provided in the outer casing, and the lens mount 7
- the spring piece 2 is elastically connected to the outer casing.
- the end of the lens holder can be connected to the bottom cover or the yoke top through a spring piece 2, and both are connected by two spring pieces.
- Translation coil 4 The symmetry is set on the periphery of the lens holder 7, and the number of the translation coils 4 can be set to two, or two or more, for example, four, etc., can be set according to the situation.
- a focus coil is provided on one end of the lens holder 7 Used to achieve lens focus.
- the inner wall of the yoke 1 is provided with a magnet 3 interacting with the translating coil 4 and the focusing coil 5, and the magnet 3 needs at least 3 It is also possible to set a plurality of coils according to the number of coils.
- the combination of the above coil and the magnet constitutes a plurality of sets of motor drives.
- the magnet 3 faces the translation coil 4 and the focus coil 5
- the sides can be of the same polarity, and the direction of the current of the translation coil 4 and the focus coil 5 is the same.
- the magnet 3 faces the translation coil 4 and the side of the focus coil 5 can also be planar two-stage magnetization, corresponding to the translation coil
- the part of 4 is a polarity
- the part corresponding to the focus coil is the other polarity, at this time, the translation coil 4 and the focus coil 5
- the current is in the opposite direction.
- control of the voice coil motor requires a minimum of 4 pins, and 3 pins correspond to 2 translation coils, 1 One pin corresponds to the focus coil and the other pin is the common ground of all coils. Due to the small number of pins required, the control chip structure used by the control unit is better than the existing OIS VCM. The chip used in the lens is much simpler.
- FIG. 1 to 3 show a first embodiment of the present invention, in which the outer casing and the lens mount are square posts, and the lens mount 7

- the four sides of the lens holder are provided with a corresponding number of translation coils 4 on the four sides of the lens relative to the magnet, and the focusing coil 5 It is located at one end of the lens holder. Therefore, the plane of the four flat push coils is perpendicular to the plane of the focus coil, and the side of the magnet 3 facing the focus coil is of the same polarity and is set to the S pole.
- Lens mount 7 The upper and lower ends are provided with a spring piece 2, and the spring piece 2 includes a movable block 21 fixed to the end of the lens holder 7, and a plurality of fixing blocks uniformly attached to the outer end of the movable block at the periphery of the movable block 22
- the movable block 21 and the fixed block 22 are connected by a plurality of elastic connecting strips 23.
- the connection point of the elastic connecting strip 23 connecting the movable block 21 is away from the connecting fixed block 22
- the connecting points are separated by a certain distance, so that the elastic connecting strip is long enough to support the movement of the lens mount.
- each coil is used 1 A common ground terminal, so that the control device used with the voice coil motor only needs to set 6 pins, 5 of which are corresponding to the coil, and 1
- the structure of the voice coil motor having the same function as in the prior art is much simpler, and the structure of the corresponding control chip is also simpler.
- FIGS. 4 to 5 show a second embodiment of the present invention, in which the housing and the lens holder of the yoke 1 ' and the bottom cover 6' are formed.
