Abstract

The present disclosure provides a lens driving device, and the device comprises a lens support cylinder for supporting at least one lens; a base which comprises a side wall part, wherein the side wallpart forms a space surrounding the lens supporting cylinder; a guide support ball member which is in contact with the outer side wall of the lens support cylinder and the inner side wall of the sidewall portion of the base, and which rolls when the lens support cylinder moves in the optical axis direction of the lens with respect to the side wall portion; and a water flow passage in the form ofa recess and provided on the lens support cylinder in the vicinity of the guide support ball member to prevent water from entering the guide support ball member. The invention further provides a camera device and electronic equipment.

Description

technical field [0001] The present disclosure relates to a lens driving device, a camera device and electronic equipment. Background technique [0002] Currently, electronic devices such as mobile phones or personal mobile terminals are equipped with a camera function. In order to enable the camera to realize functions such as automatic zoom, optical zoom, or optical image stabilization, it is necessary to use a lens driving device capable of driving a lens. [0003] The lens driving device uses the driving force generated by the actuator to drive the lens, thereby changing the distance of the lens, thereby realizing functions such as zooming or focusing. [0004] However, in the manufacturing process of the lens driving device, many components are required, the manufacturing cost is high, and the manufacturing process is complicated, so the manufacturing is relatively difficult. At the same time, during the operation of the lens driving device, it is necessary to perform s...
