Rotating shaft mechanism and aircraft with same

Abstract

The invention discloses a rotating shaft mechanism and an aircraft with the same. The rotating shaft mechanism comprises a rotating shaft, a first supporting part, a second supporting part and an elastic part, wherein the second supporting part is connected with one end of the rotating shaft; the first supporting part and the elastic part respectively sleeve the rotating shaft; a limiting platformis arranged on the rotating shaft; one end of the elastic part is abutted against the first supporting part and the other end of the elastic part is directly or indirectly abutted against the limiting platform; the side, away from the elastic part, of the first supporting part is abutted against the second supporting part; first convex platforms and first concave platforms, which are arranged ina spaced manner around the central axis of the first supporting part, are arranged on the end surface, close to the second supporting part, of the first supporting part; and second concave platforms which cooperate with the first convex platforms, and second convex platforms which cooperate with the first concave platforms, are arranged on the end surface, close to the first supporting part, of the second supporting part. The rotating shaft mechanism is structurally connected, is stable in connection and is low in manufacturing cost; and the pre-pressing effect of the elastic part on the firstsupporting part allows the aircraft adopting the rotating shaft mechanism to be free from the arm loosening situation during the flight.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a rotating shaft mechanism and an aircraft with the rotating shaft mechanism. Background technique [0002] In recent years, the domestic unmanned aerial vehicle market has been thriving, and more and more consumers are buying and using aircraft. [0003] In the process of research and development, those skilled in the art mainly conduct research and development from several aspects such as the function, safety, portability and service life of the aircraft. In terms of portability research, foldable aircraft is undoubtedly a strong stroke in the history of aircraft development. [0004] The foldable aircraft includes a fuselage, an arm and a rotating shaft mechanism. The fuselage and the arm are connected through the rotating shaft mechanism. When the aircraft is in operation, the arms are in an unfolded state; [0005] However, the structure of the existing ro...

AI Technical Summary

Problems solved by technology

[0005] However, the structure of the existing rotating shaft mechanism is complex, and the vibration generated by the aircraft during high-speed flight often leads to loosening of parts in the rotating shaft mechanism, which in turn leads to unstable connection between the arm and the fuselage
