Abstract

The present invention provides a lens driving device, comprising: a fixed frame; a first support frame sleeved on the fixed frame; a second support frame sleeved on the first support frame; The frame can rotate around the first direction relative to the first support frame, and make the first support frame rotate around the second direction relative to the second support frame; a driving assembly drives the fixed frame around the The first direction rotates relative to the first support frame, and drives the first support frame to rotate relative to the second support frame around the second direction; flexible circuit board; first elastic support member; second elastic supporting item. Compared with the related technology, the lens driving device of the present invention increases the distance between the intersections of the shape memory wires, so that it has enough space for movement during movement, and avoids mutual interference of the shape memory wires 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...
