Abstract

The present invention provides a small lens driving device with excellent focus adjustment and hand shake correction. The lens driving device comprises: a casing (10), which includes a fixing base (13) with a circuit board and a cover (12) forming a receiving space; a spring piece (50), which connects the lens module (30) and the support frame (20); supporting member (40), which is used to support the supporting frame (20) on the housing (10); magnetic steel (60), which is installed and fixed on the supporting frame (20); the first driving coil (70), which is installed on the lens module (30), and can move in the direction of the optical axis through electromagnetic action; and a second driving coil, which is arranged on the fixing base (13), and is connected to the The upper part of the magnetic steel (60) is relatively arranged near the horizontal plane of the center of gravity position (32) of the lens module. Move in the direction of intersection.

Description

technical field [0001] The invention relates to the field of driving devices, in particular to a lens driving device with an anti-shake function. Background technique [0002] With the rapid development of photographic technology, lens driving devices are widely used in numerous photographic devices. Applying the lens driving device to various portable electronic devices, such as mobile phones, tablet computers, etc., is especially accepted by consumers. [0003] A driving mechanism of a lens driving device suitable for general portable electronic equipment is generally formed of a coil and a permanent magnet, and the coil is fixed to the outer periphery of the imaging lens frame. When an electric current is applied to the coil, the coil moves the imaging lens frame and moves the imaging lens frame along the optical axis direction of the lens by the action of electromagnetic force, thereby enabling focusing. However, when a user takes an electronic device with a hand and t...
