Description

[0001] The present invention relates to a camera lens module,

The present invention relates to a camera lens module mounted on a portable mobile device, and more particularly, to a camera lens module having a shake correction function and an auto focus function.

[0002] In recent years, portable terminals such as smart phones (hereinafter referred to as " mobile ") have become multi-converged with music, movies, TVs, games, One of the factors leading to the development of the camera lens module (camera lens module) is.

The camera lens module mounted on the mobile phone has various additional functions such as an auto focus function (AF) and an optical zoom function (OPTICAL ZOOM) in order to meet the recent change in the center of high picture and high function according to the user's demand . In recent years, various attempts have been made to implement an optical image stabilizer in a mobile size.

The hand shake correction technique is a technique for automatically maintaining the focus of the correction lens constituting the camera module so as to move in the direction corresponding to the hand shake, thereby optimally maintaining the resolution of the captured image. In order to implement the camera shake correction technique, a camera module applied to a mobile device, a camcorder, and the like is equipped with an actuator for shake correction for adjusting the focus.

As a hand shake correction actuator, a VCM (Voice Coil Motor) type using a magnetic field and an electric field interaction is well known. The VCM type usually includes a magnetic circuit composed of a coil and a magnetic body arranged in a face-to-face relationship, and moves a driving part (mover) on which the lens is mounted by a magnetic force generated by a magnetic circuit in a planar manner so that correction corresponding to the vibration is performed.

In general, a method is adopted in which four magnetic circuits are applied, two pairs of which face each other in two axial directions so that vibration correction can be performed by moving a driving part in the X and Y 2-axis directions. However, in order to apply the four magnetic circuits, a large accommodation space is required, and therefore, the overall size is increased, and the device configuration becomes complicated, making it difficult to achieve miniaturization of the product.

Reducing the size and number of parts of the driving unit is advantageous in compactly configuring the module, but there is a problem in that precision and speed of correction of hand shake are inferior. Especially, the resultant force of orthogonal forces in the directions of X, There is a problem in that the accuracy of correction is degraded due to unnecessary rotation when the driving part is driven beyond the driving range or when the driving part is driven.
