Problems solved by technology

[0003] At present, there are still some problems with the compound-wing UAVs on the market. After the rotor propeller stops, it will change continuously with the change of the airflow during the cruise process, which will not only increase the flight resistance, but also have a corresponding dynamic impact on the aircraft.
For some compound-wing UAVs with short landing gear or no landing gear, the attitude of the aircraft is uncertain due to external interference during landing, which may easily lead to propeller propulsion or pulling in the propeller to touch the ground and cause damage

Embodiment Construction

[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to t...

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to a propeller directional locking mechanism. The mechanism comprises a propeller, a motor, a motor rotating shaft of the motor, a motor fixing support, a magnet fixing support, a plurality of sets of first magnets fixed on the motor fixing support and a plurality of sets of second magnets fixed on the magnet fixing support, when the motor stops rotating or is going to stop rotating, different magnetic poles of the first magnets and the second magnets are attracted mutually, and the position of a propelleris locked in a directional mode. The mechanism is simple in structure, a rotor wing propeller of a composite wing unmanned aerial vehicle can be locked to be in a position consistent with a cruising direction during cruising, the flight resistance is reduced, and the cruising time and range of an aircraft are increased.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a propeller directional locking mechanism. Background technique [0002] The compound-wing vertical take-off and landing UAV is an aerodynamic layout UAV combining fixed wings and rotors, which solves the problem of vertical take-off and landing of fixed-wing UAVs in a simple way. Combining the advantages of fixed-wing UAVs with long endurance, high speed, long range and vertical take-off and landing of rotary-wing UAVs, these characteristics make compound-wing UAVs have a wide range of application prospects. The demand for composite wing vertical take-off and landing drones is increasingly urgent in the fields of oil pipeline inspection, power inspection, forest fire prevention and other fields. [0003] At present, there are still some problems with the compound-wing UAVs on the market. After the rotor propeller stops, it will change continuously with the chan...
