Propeller and wheel paddle assembly of aircraft automobile by adopting propeller

Abstract

The invention relates to the technical field of aircrafts, in particular to a propeller and a wheel paddle assembly of an aircraft automobile by adopting the propeller. A rotary telescopic type propeller is adopted and comprises paddle blades, a paddle shaft and a sliding groove sleeve assembled on an aircraft and driven to rotate by a driving mechanism; the top end of the paddle shaft is fixedlyassembled and connected with the paddle blades, the sliding groove sleeve slidably sleeves the middle of the paddle shaft, so that the paddle shaft performs forward and reverse lifting motion relativeto the sliding groove sleeve; folding paddle blades are adopted in the paddle blades and comprise two auxiliary paddles symmetrically arranged on the two sides of the top end of the paddle shaft, a main paddle in pin joint with the outer ends of the auxiliary paddles and a torsional spring, wherein two ends of the torsional spring are separately connected with the auxiliary paddles and the main paddle and used for folding and shrinking the propeller; and when the paddle shaft rotates, after centrifugal force of the main paddle overcomes twisting force of the torsional spring, the paddle blades can automatically rotate and be unfolded. Compared with the prior art, rotary telescopic type is adopted in the propeller, volume reducing is facilitated, propeller is applied to folding paddles, and thus, the folding paddles are unfolded through inertial rotation.

Description

technical field

[0001] The invention relates to the technical field of aircraft, in particular to a propeller and a wheel and propeller assembly of an aircraft vehicle using the propeller. Background technique

[0002] Existing aircraft or wheeled mobile platforms have their limitations. Although wheeled mobile platforms have certain advantages in carrying capacity and transportation capacity, they have high requirements on road conditions. Due to environmental constraints, the ground roads are now complex and congested, and the traffic efficiency is low. . Although the flight of the aircraft is not restricted by the ground, it has poor adaptability to the take-off and landing environment. At present, there is no mobile transportation device that can take care of these two problems well at the same time.

[0003] The existing technical solution is to insert the propeller directly into the wheel. The disadvantage of this solution is that the propeller is small in size, the ...
