Lens support, lens driving device, camera device and electronic equipment

Abstract

The invention belongs to the technical field of optical anti-vibration, and particularly relates to a lens support, a lens driving device, a camera device and electronic equipment. The technical problem that an existing support is poor in deformation resistance is solved. The lens support includes a translation frame that moves in a plane perpendicular to an optical axis; a magnetism increasing reinforcer is included, is fixed on the translation frame and is used for reinforcing the radial structure and / or the axial structure of the translation frame; and the magnetism increasing reinforcer is used for uniformly increasing the magnetism of the first magnet and / or the second magnet which takes the axis of the translation frame as the center. The lens support has the advantages that the magnetism increasing reinforcer not only can reinforce the structure of the translation frame, but also can be matched with the first magnet and / or the second magnet to enhance the magnetic field intensity so that the thrust is increased, the high thrust requirement of the motor is met, the stability of the whole motor structure can be enhanced, the structure is not easy to loosen, the service life of the O I S motor is greatly prolonged, and the stability of use performance is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of optical anti-shake, and in particular relates to a lens holder, a lens driving device, an imaging device and electronic equipment. Background technique [0002] In a voice coil motor, the components in the housing need to be installed and positioned through the support. In order to ensure the smooth operation of the voice coil motor, it is first necessary to ensure the stability of the support itself in the housing. The commonly used support uses the joint surface to cooperate with the inner wall of the housing. After a long period of use, the support deforms, its position shifts in the housing, and causes other components in the motor to loosen with the support. adversely affect the overall performance of the system. [0003] Secondly, the AF electromagnetic thrust and / or the OIS electromagnetic thrust of the existing voice coil motor is relatively small, which cannot meet the requirement of high thrust...
