Title: DRONE CAPABLE OF VARYING PROPELLER ARRANGEMENT SHAPE
Abstract:
Disclosed is a drone having a deployment device, which is configured such that the same can fly both in a folded mode and in a deployed mode, thereby being able to vary the propeller arrangement shape. A platform (300) is arranged in the middle of the drone body (400), a deployment device (200) is arranged on the radial outer side of the platform (300), a fixed support table (230) extends outwardly from the radial outer surface of the platform (300) by a predetermined length, a rotating support table (210) is coupled to an outer free end of the fixed support table (230), and the rotating support table (210) is rotatably coupled to/supported on the outer free end of the fixed support table (230) by a hinge device (220) or a motor (250). Multiple propellers (100) are mounted on the radial outer ends of the rotating support table (210), respectively, a landing structure (600) is integrally coupled to the lower portion of the body (400), and a holder (500) is integrally mounted on the inner lower surface of the landing structure (600). The drone according to the present invention differentially adjusts the angle of deployment of the propellers that operate normally in the deployed mode and thus maintains the posture balance, thereby being able to secure flight stability.
