Abstract

Disclosed herein is a camera lens module. The camera lens module in accordance with an embodiment of the present invention includes a vibration correction carrier, a rolling unit disposed in parallel to a direction vertical to an optical axis and configured to support the vibration correction carrier, a lens barrel carrier disposed on a side opposite the vibration correction carrier based on the rolling unit, and a base configured to mount the vibration correction carrier and the lens barrel carrier on the base.

First claim

What is claimed is:

1. A camera lens module, comprising:
a vibration correction carrier adapted to receive a lens barrel;
devices disposed in parallel in a direction perpendicular to an optical axis and adapted to support the vibration correction carrier and to provide a centering of the vibration correction carrier;
a lens barrel carrier disposed on a side opposite to the vibration correction carrier that is mounted on the devices that center the vibration correction carrier; and
a base adapted to have the vibration correction carrier and the lens barrel carrier mounted on the base,
wherein the vibration correction carrier is movable in any direction on a plane that is perpendicular to the optical axis,
wherein the devices providing the centering of the vibration correction carrier comprise:
a plurality of ball bearings that are disposed between the lens barrel carrier and the vibration correction carrier to support the vibration correction carrier; and
at least one yoke disposed to face the vibration correction carrier on the lens barrel carrier side, and
wherein the yoke is located at a distance from the optical axis in a radial direction in the plane and a center of at least one of the plurality of ball bearings is positioned on an outer side of an imaginary line extending through a center of the yoke in a direction perpendicular to the radial direction in the plane.

2. The camera lens module of claim 1 , further comprising:
an automatic focus driving unit disposed on one side between the base and the lens barrel carrier; and
two or more vibration correction driving units spaced apart from each other between the base and the vibration correction carrier on an opposite side of the automatic focus driving unit.

3. The camera lens module of claim 1 , wherein:
the lens barrel carrier comprises a plurality of sides,
one of the plurality of sides is closed and remaining sides of the plurality of sides are configured to be at least partially open or fully open,
an automatic focus magnet is disposed in the closed side, and
the vibration correction carrier is disposed in the open portion.

4. The camera lens module of claim 1 , wherein a pair of the ball bearings are positioned on the outer side of the imaginary line.

5. The camera lens module of claim 4 , wherein the pair of ball bearings are disposed on both sides of the yoke, respectively.

6. The camera lens module of claim 4 , wherein a line connecting centers of the pair of ball bearings is parallel to the imaginary line.

7. The camera lens module of claim 6 , wherein the pair of ball bearings are disposed on both sides of the yoke, respectively.
