Problems solved by technology

[0004] However, to achieve autofocus and / or optical image stabilization, the connecting shrapnel needs to be easily deformed, and the connecting shrapnel needs to have a certain strength so as not to deform too much during reliability processes such as dropping and impacting
Therefore, the current motors used to drive liquid lenses are difficult to meet both performance requirements and reliability requirements

Abstract

The invention provides a motor assembly for driving a liquid lens, a camera module and electronic equipment. The motor assembly includes: a stator portion; a mover portion movable in an optical axis direction with respect to the stator portion; a connecting elastic sheet which is connected with the liquid lens and the mover portion, wherein the mover portion drives the connecting elastic sheet toextrude or pull the liquid lens when being subjected to acting force in the optical axis direction; and a limiting part which moves along with the mover portion, has the same displacement as the moverportion, and is used for limiting the height change range of the connecting elastic sheet in the optical axis direction. According to the technical scheme, the motor used for driving the liquid lenscan meet the performance requirements of automatic focusing and / or optical anti-shake and the like, and the reliability of the motor under abnormal working conditions such as impact and falling is improved.

Description

technical field [0001] The present application relates to the field of lens driving devices, in particular to a motor assembly for driving a liquid lens, a camera module and electronic equipment. Background technique [0002] In order to meet people's demand for camera miniaturization, a liquid lens with variable curvature is used as an optical lens in the camera module to realize auto-focus and / or optical image stabilization. [0003] In one implementation, the motor can transmit displacement to the liquid lens through the connecting shrapnel. For example, the motor drives the connecting shrapnel to move, and the connecting shrapnel then squeezes or pulls the liquid lens. The curvature of the liquid lens changes to achieve the purpose of zooming. [0004] However, to achieve autofocus and / or optical image stabilization, the connecting shrapnel needs to be easily deformed, and the connecting shrapnel needs to have a certain strength so as not to deform too much during reliab...
