Description

Technology Field

[0001] This embodiment relates to a camera device. Background Technology

[0002] A camera device is a device that captures a subject as a photo or video, and is installed in optical devices such as smartphones, drones, vehicles, etc.

[0003] In camera devices, a hand shake correction (Optical Image Stabilization, OIS) function is required to correct image shaking caused by user movement in order to improve image quality.

[0004] In camera devices, image stabilization is performed by moving the lens in a direction perpendicular to the optical axis. However, due to the recent trend toward higher pixel counts, the diameter of the lens increases, leading to an increase in lens weight. Consequently, there is a problem in that it is difficult to secure the electromagnetic force required to move the lens within a limited space.

[0125] In this embodiment, to prevent buckling (deformation) of the wire (800) due to impact, only the wire at the location where the damper (900) is applied may be formed with an increased diameter. The diameter of 4 or 8 of the 36 wires may be increased. In this embodiment, the safety load may be increased by applying a thicker diameter to the second wire (820).

[0126] FIG. 14 is buckling analysis data according to the diameter of the wire of the camera device and whether or not a damper is applied, according to the present embodiment.

[0127] In the case of a comparative example where the wire diameter is 30 µm and no damper is applied, the buckling load is 20.0 mN and the spring load is 2.5 mN, so the safety load can be 17.5 mN.

[0128] In the case where the wire diameter is 60 µm and the damper (900) is applied, such as with the second wire (820) of this embodiment, the buckling load is 320.0 Nm and the spring load is 2.6 mN, so the margin load can be 317.4 mN. That is, according to this embodiment, a larger margin load than that of the comparative example can be secured. Through this, the wire deformation phenomenon occurring after an impact test can be improved. That is, a reliability margin can be secured.

[0129] In the comparative example and the present embodiment, the length of the wire may be 2.27 mm. The buckling load may be the minimum load at which wire buckling occurs. The spring load may be the compressive force received by the terminal (372) of the terminal member (370) due to elasticity. The clearance load may be the value obtained by subtracting the spring load from the buckling load. The clearance load may be a margin capable of accommodating the damping load and the impact load. The larger the clearance load value, the greater the effect of preventing wire buckling.
