[0001] GIMBAL ASSEMBLY FOR DRONE [0002]

The present invention relates to a gimbal assembly for a drone, and more particularly, to a gimbal assembly for a drone in which a position of a camera mounted on a drone can be freely adjusted and a position can be accurately and finely adjusted.

Drone is a unmanned aerial vehicle that was originally developed for military purposes to enable reconnaissance or direct physical hitting of war zones or avenues, but recently it has been developed for various purposes not limited to military purposes.

For example, the drones are much lighter and easier to operate than airplanes, so they can be used for broadcasting, and more recently, drones are being used to deliver articles or mail.

The drones are also being used for water rescue structures that can be manipulated to deliver life-saving tubes to survivors.

Attempts have been made to increase the application range of the dron by mounting various tools to the dron according to the utilization of the user. In view of the above, in the above-mentioned Patent No. 10-1302442 entitled " Unmanned Aircraft Camera Folding Device " Hereinafter referred to as " prior art ").

The prior art allows the camera to be tilted to secure a wide shooting range of the camera mounted on the unmanned aerial vehicle.
