Abstract

The invention provides an automatic propeller torque changing mechanism. The automatic propeller torque changing mechanism comprises at least one paddle, a flow guiding cover, a propeller base, a propeller hub and a drive device driving the propeller hub to rotate. The two ends of the propeller hub are connected with the flow guiding cover and the drive device correspondingly. Each paddle is provided with a paddle root and a paddle tip. An installing cavity is formed in the propeller base, the propeller base is provided with installing holes corresponding to the paddle roots, the paddle roots penetrate through the installing holes, the paddle roots are connected with the propeller hub through rotation devices, the propeller hub is inserted in the installing cavity, and an elastic piece is connected between the top end of the propeller base and the bottom end of the flow guiding cover. The automatic propeller torque changing mechanism can solve the problems that an unmanned aerial vehicle in the prior art cannot achieve automatic torque changing, and consequently the pneumatic efficiency is reduced.

Description

technical field [0001] The invention relates to the technical field of propellers, in particular to a propeller automatic torque conversion mechanism. Background technique [0002] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be at least one blade connected to the hub, and the rear side of the blade is a helical surface or a propeller similar to a helical surface. . There are many types of propellers, and they are widely used, such as propellers for aircraft and ships. UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned Airships, unmanned helicopters, unmanned multi-rotor aircraft and unmanned paragliders. Compared with manned aircraft, it has the advantages of ...
