Abstract

The invention discloses a propeller device of an air moving tool. The propeller device comprises a hub; a plurality of wings connected to the hub; a rotating shaft transmitting a rotational force to the hub to rotate the hub and the wing; a first moving part and a second moving part provided to independently move up and down on the rotating shaft; the first connecting rod assembly is connected with the first moving part and the multiple wings, and when the first moving part moves up and down, the multiple wings rotate in situ to achieve longitudinal swing operation; and the second connecting rod assembly is connected with the second moving part and the wings, and when the second moving part moves up and down, the wings rotate and move so as to realize folding or unfolding operation. According to the propeller device of the air moving tool, the wings are unfolded or folded according to the flight state of the air moving tool, the energy efficiency is improved by effectively utilizing the wings under various flight conditions, and the flight distance is increased. In addition, in addition to an unfolding or folding operation of the wings, a pitch operation is achieved, thereby ensuring flight performance.

Description

technical field [0001] The present invention relates to a propeller device of an aerial mobile tool, in particular, to a propeller device of an aerial mobile tool that unfolds or folds the wings according to the flight state. Background technique [0002] In recent years, aerial mobile tools that can be used in various fields such as cargo containers and medical transportation are being developed, and the energy efficiency and stability of flying mobile tools have been improved and entered a practical stage. [0003] This aerial mobile tool flies by the operation of the propeller, thereby realizing vertical take-off and landing. However, during the vertical take-off and landing of the aerial mobile tool, it is necessary to use more thrust and more propellers than in the flight state. On the other hand, when the aerial mobile tool enters the flight state, it can fly by the lift of the wings, so there is no need to run some of the propellers used in vertical take-off and land...
