Title (EN) MULTI-AXIS VOICE COIL MOTOR
(FR) MOTEUR À BOBINE MOBILE À AXES MULTIPLES
(ZH) 一种多轴音圈马达
Abstract:
(EN) The present invention is applicable to the field of camera drive devices and provides a multi-axis voice coil motor, comprising: a metal magnetic yoke, an upper cover terminal, a lower cover terminal, an upper spring, a lower spring, a lens seat, and a support; at least two anti-shake coils are provided on the lens seat, an outer side of each anti-shake coil being provided with an anti-shake magnet, and a face of the anti-shake magnet that is close to the anti-shake coil simultaneously having a horizontally distributed N-pole and S-pole; at least two focusing coils are provided on the support, an outer side of each focusing coil being provided with a focusing magnet, and a face of the focusing magnet that is close to the focusing coil simultaneously having a vertically distributed N-pole and S-pole; the upper spring and the lower spring are arranged on the upper cover terminal and the lower cover terminal, respectively, the upper cover terminal being buckled on the lower cover terminal; the lens seat and the support are connected to the upper spring and the lower spring, respectively, and the anti-shake magnet and the focusing magnet are both fixed between the upper cover terminal and the lower cover terminal. The motor achieves focusing, optical anti-shake, and optical axis correction functions for the motor by means of a brand-new magnetic path. The motor has a small size and will not produce magnetic interference.
(FR) La présente invention peut être appliquée au domaine des dispositifs d'entraînement d'appareil de prise de vues et concerne un moteur à bobine mobile à axes multiples, comprenant : une culasse magnétique métallique, une borne de couvercle supérieur, une borne de couvercle inférieur, un ressort supérieur, un ressort inférieur, un siège de lentille et un support. Au moins deux bobines anti-tremblement sont disposées sur le siège de lentille, un côté extérieur de chaque bobine anti-tremblement étant pourvu d'un aimant anti-tremblement et une face de l'aimant anti-tremblement qui est proche de la bobine anti-tremblement ayant simultanément un pôle N et un pôle S distribués horizontalement. Au moins deux bobines de mise au point sont disposées sur le support, un côté extérieur de chaque bobine de mise au point étant pourvu d'un aimant de mise au point et une face de l'aimant de mise au point qui est proche de la bobine de mise au point ayant simultanément un pôle N et un pôle S distribués verticalement. Le ressort supérieur et le ressort inférieur sont respectivement disposés sur la borne de couvercle supérieur et la borne de couvercle inférieur, la borne de couvercle supérieur étant attachée sur la borne de couvercle inférieur. Le siège de lentille et le support sont respectivement reliés au ressort supérieur et au ressort inférieur, et l'aimant anti-tremblement et l'aimant de mise au point sont tous deux fixés entre la borne de couvercle supérieur et la borne de couvercle inférieur. Le moteur réalise la mise au point, l'anti-tremblement optique et des fonctions de correction d'axe optique pour le moteur au moyen d'un trajet magnétique totalement nouveau. Le moteur présente une petite taille et ne produit pas d'interférences magnétiques.
(ZH) 本发明适用于摄像驱动设备领域,提供了一种多轴音圈马达,包括金属磁轭、上盖端子、下盖端子、上弹簧、下弹簧、镜头座以及支架,镜头座上设置有至少两个防抖线圈,每一个防抖线圈的外侧设有防抖磁铁,防抖磁铁靠近防抖线圈的一面同时存在左右分布的N极和S极;支架上设有至少两个对焦线圈,每一个对焦线圈的外侧设有对焦磁铁,对焦磁铁靠近对焦线圈的一面同时存在上下分布的N极和S极;上、下弹簧分别设置在上、下盖端子上,且上盖端子扣盖在下盖端子上,镜头座和支架分别与上、下弹簧连接,防抖磁铁和对焦磁铁均固定在上、下盖端子之间。该马达通过全新的磁路实现马达的对焦、光学防抖和光轴矫正功能,不仅体积小,而且不会产生磁干扰。
