TWO AXIS CAMERA MODULE VIBRATION DAMPING SYSTEM

Technical Field

The invention relates to a two-axis camera module vibration damping system, which performs the function of reducing the shake of the recorded videos by mounting the camera and its components, dampening the movement, and mitigating the shock forces, and providing the possibility to be connected in the horizontal and vertical axis.

Background of the Invention

Today, recording with cameras in air, sea and land vehicles is frequently performed. These cameras, which serve many purposes such as viewing a possible accident moment or recording images of the surroundings while in motion, cause a shaky image to be recorded when mounted on air, sea and land vehicles due to the vibrations emitted by these vehicles.

Especially in rough terrains or during a possible military operation, the aforementioned tremors are much more, causing the quality of the recorded images to be poor.

Cameras that are damaged over time due to shaking also need to be replaced or repaired over time. This significantly increases the cost of users.

Regarding the subject in the Korean patent application numbered KR20120099361 in the literature, “A camera module according to the present invention includes a lens barrel including one or more imaging lenses, an auto-focusing driving unit for moving the lens barrel in an optical axis direction, and an image-stabilization driving unit for moving the lens barrel in a direction orthogonal to an optical axis. The auto-focusing driving unit and the image-stabilization driving unit include an auto-focusing and imagestabilization driving common magnet, an auto-focusing corner magnet, a coil for auto focusing, and a coil for image-stabilization. One surface of the auto-focusing and image-stabilization driving common magnet and the auto-focusing corner magnet face the coil for auto focusing. The other surface of the auto-focusing and imagestabilization driving common magnet faces the coil for image-stabilization. The autofocusing and image-stabilization driving common magnet and the auto-focusing corner magnet facing the coil for auto-focusing are magnetized in the same pole.” statements are included.

In the mentioned application, a damping mechanism that can be magnetically damped with the help of a magnet is described.

The device comprises a base and a camera suspending frame arranged on the base. The device is characterized in that vertical dampers having the effect of vertical arms of feree and a chassis supporting the dampers are respectively arranged between the base and the camera suspending frame; cross arm type dampers are respectively arranged around the camera suspending frame, and connected with the camera suspending frame in a hoisting manner.
