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 application provides a motor assembly for driving a liquid lens, a camera module and electronic equipment. The motor assembly includes a stator part; a mover part, relative to the stator part, the mover part can move along the direction of the optical axis; connecting shrapnels, respectively connecting the liquid lens and the mover part, the mover part is affected in the direction of the optical axis When the force is applied, the connecting shrapnel is driven to squeeze or pull the liquid lens; the limiting part, which moves with the mover part and has the same displacement as the mover part, is used to limit the connecting shrapnel in the direction of the optical axis. range of height variation. The above technical solution enables the motor used to drive the liquid lens to meet performance requirements such as autofocus and / or optical anti-shake, while improving the reliability of the motor under abnormal working conditions such as impact and drop.

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...
