Propeller capable of being automatically folded and unfolded

Abstract

The propeller capable of being automatically folded and unfolded comprises a driving motor and two propeller bodies above the driving motor, a fixing plate is fixedly connected to the top of an output shaft of the driving motor, and a rectangular cover with the bottom open is fixedly connected to the top of the fixing plate; the two sides of the rectangular cover are each fixedly connected with two supports, a first rotating shaft is rotationally installed between the two supports located on the same side, and the side, away from the rectangular cover, of the first rotating shaft is fixedly connected with two connecting rods. The two propeller bodies can be conveniently and rapidly controlled to automatically and synchronously rotate and fold downwards, the transverse space occupied by the propeller bodies when the propeller bodies are not used is reduced, then personnel can conveniently store and carry the propeller bodies, the propeller bodies can be conveniently and independently disassembled and assembled, the personnel can conveniently and rapidly replace the damaged propeller bodies in the follow-up process, the replacement efficiency is improved, and the practicability is high. The use requirements are met and the use is facilitated.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle propellers, in particular to an automatically foldable and unfoldable propeller. Background technique [0002] A propeller is a device that rotates in the air by the blades and converts the rotational power into propulsion. There may be two or more blades connected to the hub. There are many types of propellers and they are widely used, such as aircraft and ships. Propellers, propellers, etc. are also basic components on many types of aircraft such as drones. [0003] Most of the propellers on the existing small unmanned aerial vehicles have the disadvantage of being inconvenient to flip and fold, so that when not in use, the two opposite propellers occupy a large lateral space, and the lateral protrusion is relatively large, making it inconvenient for personnel It can be stored and carried; and most of them have the disadvantage that it is not convenient to quickly disassemble an...

Problems solved by technology

[0003] Most of the propellers on the existing small unmanned aerial vehicles have the disadvantage of being inconvenient to flip and fold, so that when not in use, the two opposite propellers occupy a large lateral space, and the lateral protrusion is relatively large, making it inconvenient for personnel It can be stored and carried; and most of them have the disadvantage that it is not convenient to quickly disassemble and replace the damaged propeller alone, the replacement efficiency is low, and it cannot meet the needs of use. question
