Camera Lens Driver

Abstract

The present invention provides a small lens driving device with excellent focus adjustment and hand shake correction. The lens drive device includes a shake correction unit (70), a lens module (80) capable of driving in a direction horizontal to the direction of reflected light and an optical axis (111), a shaft (81) for supporting the lens module, and an upper cover (11). , a lower cover (12), a magnet (90), a coil (91) and a yoke (92), the shake correction part (70) has a prism (16), a prism cover (17), a second holding frame (30), The support member (40) for biaxial support, the shaft a (42) of the shake correction part and the shaft b (43) of the shake correction part, the prism (16) can rotate in one direction with respect to the incident light and the optical axis (110). a (112), rotate in one rotation direction b (113), and be installed on the first holding frame (20) on the base (10) for fixing.

Description

technical field [0001] The invention relates to the field of driving devices, in particular to a camera 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] The driving mechanism of the lens driving device suitable for ordinary portable electronic equipment is usually formed by a coil and a magnetic steel, and the coil is fixed on the outer periphery of the lens holder. When a current is applied to the coil, the coil moves the lens holder and moves the lens holder along the optical axis direction of the lens by the action of electromagnetic force, thereby enabling focusing. In addition, when the user holds the electronic device in his hand and takes pictures, t...

Problems solved by technology

However, for example, in a compact optical device mounted on a portable electronic device and a zoom optical system with a long optical total length, it is difficult to directly mount it on a portable electronic device, and a structure such as a bend is required.

[0004] In the optical system using this curved structure, it is possible to use lenses arranged in front and rear of a prism or reflector for bending light for shake correction. The shake correction structure of the lenses arranged on the front and rear may increase the overall length of the curved optical system, or may become a structure that must protrude a part of the shape
