Abstract

The invention discloses a lens driving apparatus. The apparatus comprises a base; a cover body connected with the base and forming an accommodating apace; a support frame accommodated inside the accommodating space; a lens module arranged in the support frame in a suspension way; a steel magnet arranged and fixed on the support frame; a focus coil arranged on the lens module and opposed to the inner surface of the steel magnet; an anti-shake coil fixed on the cover body and right opposed to the outer surface of the steel magnet; a position detection element located inside a center hole of the anti-shake coil; and a first elastic element comprising a pair of first spring pieces arranged in a central symmetry way. Each first spring piece comprises a first elastic part connecting the lens module and the support frame, a second elastic part connecting the support frame and the base and a third elastic part connecting the first elastic part and the second elastic part.

Description

【Technical field】 [0001] The invention relates to the field of driving devices, in particular to a lens driving device. 【Background technique】 [0002] Recently, high-performance lens drive devices have been installed in portable terminal devices such as portable cameras, smartphones, and tablet PCs. These lens driving devices generally have autofocus and anti-shake functions. The anti-shake feature reduces blur caused by external vibrations or the shaking of the user's hand. . [0003] In an existing lens driving device with an anti-shake function, in order to realize automatic focusing, the focusing coil is energized to drive the lens up and down along its optical axis. However, in these lens driving devices, components such as suspension wires and wire springs are required in order to introduce current from outside the lens module to the focusing coil. The suspension wire relies on the elastic restoring force to prevent shaking, thereby prompting the lens driving devi...
