Magnets (3) of the motor are fixed on the inner side of a metal yoke (2); a lens holder (1) and coils are suspended in the metal yoke (2) by means of an upper spring (4) and a lower spring (5), the metal yoke (2) being used for shielding an external magnetic field to prevent external magnetic interference. When anti-shake coils (9) are energized, the magnets (3) apply an acting force to the anti-shake coils (9) to push the lens holder (1) to move in any direction perpendicular to the plane of an optical axis, thereby realizing an optical anti-shake function. When a focusing coil (8) is energized, the magnets (3) apply to the focusing coil (8) an acting force parallel to the optical axis, causing the lens holder (1) to move in an optical axis direction to achieve focusing. The moving parts of the motor are not provided with magnets and thus are not susceptible to external magnetic fields. Therefore, there is no mutual magnetic field interference between two motors in close proximity, and the motor is applied to the dual-camera dual optical anti-shake module with the optical ant-shake function.

有益效果Beneficial effect
本发明与现有技术相比，有益效果在于：本发明的三轴平移光学防抖音圈马达，其镜头座外侧罩设有金属磁轭，磁铁固定安装在金属磁轭内侧面上；镜头座以及线圈通过上弹簧和下弹簧悬挂在金属磁轭内，金属磁轭能够屏蔽外界磁场，防止外界的磁干扰。Compared with the prior art, the present invention has the beneficial effects that the three-axis translation optical anti-shake voice coil motor of the present invention has a metal yoke on the outer side of the lens holder, and the magnet is fixedly mounted on the inner side of the metal yoke; And the coil is suspended in the metal yoke by the upper spring and the lower spring, and the metal yoke can shield the external magnetic field and prevent external magnetic interference.
当防抖线圈通电时，磁铁可对两个绕线平面相互垂直的防抖线圈产生两个正交方向的力，这两个力所在的平面垂直于光轴（即镜头座的轴向），这样就能推动镜头座在垂直于光轴所在平面内任意方向的可控运动，实现光学防抖功能。当对焦线圈通电时，磁铁的磁场向对焦线圈产生一个平行于光轴的作用力，使镜头座沿着光轴方向前后移动，从而实现对焦。When the anti-shake coil is energized, the magnet can generate two orthogonal directions of force to the anti-shake coils of the two winding planes perpendicular to each other, and the plane of the two forces is perpendicular to the optical axis (ie, the axial direction of the lens holder). In this way, the controllable movement of the lens holder in any direction perpendicular to the plane of the optical axis can be promoted, and the optical image stabilization function can be realized. When the focus coil is energized, the magnetic field of the magnet generates a force parallel to the optical axis to the focus coil, causing the lens mount to move back and forth along the optical axis direction to achieve focusing.
本发明的马达机构体积小、结构简单，其中多个线圈可串联或者并联，组成至少三组以上独立工作的线圈组，分别控制三个自由度方向的运动。马达的内部运动部分为镜头座以及线圈，镜头座可以采用塑料制作，由于运动部件没有磁铁，重量轻，功耗低，不易受到外界磁场的影响。所以，位置靠近的两个马达之间亦不会产生相互的磁场干扰，将该马达应用在双摄双光学防抖模组中，可使模组具备光学防抖功能。The motor mechanism of the invention has small volume and simple structure, wherein a plurality of coils can be connected in series or in parallel to form at least three groups of independent working coil groups, respectively controlling the movement in three degrees of freedom. The internal movement part of the motor is a lens holder and a coil. The lens holder can be made of plastic. Since the moving parts have no magnet, the weight is light, the power consumption is low, and it is not easily affected by the external magnetic field. Therefore, there is no mutual magnetic field interference between the two motors located close to each other. The motor is applied to the dual-camera dual optical anti-shake module, so that the module can have an optical anti-shake function.
