A propeller locking mechanism and an unmanned aerial vehicle power device comprising the same

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and specifically relates to a propeller locking mechanism and an unmanned aerial vehicle power device comprising the same. Thepropeller locking mechanism is used for locking a propeller; the propeller is driven by a motor; the motor comprises a rotating shaft, and one end of the rotating shaft is connected with the propeller; the locking mechanism comprises an angle limiting block, a push-pull mechanism and an ejector block, and the other end of the rotating shaft is connected with the middle of the angle limiting block; the push-pull mechanism is connected with the ejector block and the ejector block pushes the angle limiting block to rotate to an appointed position to be locked. According to the propeller lockingmechanism and the unmanned aerial vehicle power device comprising the propeller locking mechanism, the propeller locking mechanism uses the push-pull mechanism (driving the ejector block to move) to lock the propeller, stopped at any position, at the position consistent with an airflow direction; the propeller locking mechanism is easy to control, the structure is compact, and integration of the mechanism on the unmanned aerial vehicle power device is easy.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a propeller locking mechanism and an unmanned aerial vehicle power device containing the same. Background technique [0002] The vertical take-off and landing fixed-wing aircraft overcomes the shortcomings of traditional fixed-wing aircraft that are restricted by the traditional taxi take-off and taxi landing methods, which lead to high requirements for runways, take-off environment and control technology; And drive the propeller to provide lift when landing, so as to realize the height control of the aircraft; for example, the Chinese utility model patent with application number 201720690129.9. [0003] The above-mentioned propellers that provide lift do not work during the level flight of the aircraft, but these propellers will rotate randomly under the action of the airflow, and the rotation of the propellers will interfere with the airflow and affect the inco...

Problems solved by technology

[0003] The above-mentioned propellers that provide lift do not work during the level flight of the aircraft, but these propellers will rotate randomly under the action of the airflow, and the rotation of the propellers will interfere with the airflow and affect the incoming flow of the wings, which not only increases the The resistance received, and it will disturb the attitude of the aircraft, affect the stable flight of the aircraft, reduce the endurance time of the aircraft, and shorten the endurance distance of the aircraft
