Abstract
(EN) The utility model provides an optical device. The optical device comprises a shell with an accommodating space, and a lens module, a spring device and a driving device which are accommodated in the accommodating space, the spring device is respectively connected with the lens module and the shell; the optical device further comprises a magnetic suspension fulcrum structure arranged between the lens module and the shell, the magnetic suspension fulcrum structure comprises a first magnetic suspension structure and a second magnetic suspension structure arranged corresponding to the first magnetic suspension structure, the first magnetic suspension structure is fixedly arranged on the lens module, and the second magnetic suspension structure is fixedly arranged on the shell. The second magnetic suspension structure is fixedly arranged on the shell, and the first magnetic suspension structure and the second magnetic suspension structure are arranged in a homopolar opposite mode so as to generate magnetic repulsive force to enable the first magnetic suspension structure and the second magnetic suspension structure not to make direct contact with each other. The optical device provided by the utility model achieves the purposes of reducing frictional resistance, avoiding abrasion and further achieving optical anti-vibration.
(ZH) 本实用新型提供一种光学装置,包括具有收容空间的壳体和收容于所述收容空间的镜头模组、弹簧装置以及驱动装置;所述弹簧装置分别与所述镜头模组和所述壳体连接;所述光学装置还包括设于所述镜头模组与所述壳体之间的磁悬浮支点结构,所述磁悬浮支点结构包括第一磁悬浮结构和与其对应设置的第二磁悬浮结构,所述第一磁悬浮结构固定设置于所述镜头模组上,所述第二磁悬浮结构固定设置于所述壳体上,所述第一磁悬浮结构与所述第二磁悬浮结构同极相对设置,以产生磁性斥力使所述第一磁悬浮结构与所述第二磁悬浮结构相互不直接接触。本实用新型提供的光学装置,达到减少摩擦阻力,避免产生磨损,进而达到光学防抖的目的。
