Problems solved by technology

In this SMA drive structure, since the shape memory wires are fixed on the outer frame and the inner frame, the movement of the shape memory wires will interfere with each other due to the small distance between the intersections, which will affect the anti-shake function.

Abstract

The invention provides a lens driving device. The lens driving device comprises: a fixing frame; a first supporting frame which is arranged on the fixing frame in a sleeving mode; a second supportingframe which is arranged on the first supporting frame in a sleeving manner; a rotating assembly which enables the fixing frame to rotate relative to the first supporting frame in the first direction and enables the first supporting frame to rotate relative to the second supporting frame in the second direction; a driving assembly which drives the fixing frame to rotate around the first direction relative to the first supporting frame and drives the first supporting frame to rotate around the second direction relative to the second supporting frame; a flexible circuit board; a first elastic supporting piece; and a second elastic supporting piece. Compared with the prior art, the lens driving device has the advantages that the distance between the staggered parts of the shape memory lines isincreased, so that the lens driving device has enough movement space during movement, and the shape memory lines are prevented from being interfered with each other during movement.

Description

technical field [0001] The invention relates to a driving device, in particular to a lens driving device. Background technique [0002] With the development of camera technology, lens driving devices are widely used in various camera devices. The combination of the lens driving device and various portable electronic devices such as mobile phones, video cameras, computers, etc., is favored by consumers. [0003] The design of the SMA driving structure of the lens in the related art is to fix one end of a plurality of shape memory wires electrically connected to the circuit board to the outer frame, and then fix the other end to the inner frame where the lens module is installed, so as to The shape memory wire is energized through the circuit board to make it shrink to generate tension to pull the inner frame to move, thereby realizing the anti-shake function of the lens. In this SMA drive structure, since the shape memory wires are fixed on the outer frame and the inner fra...
