Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] This embodiment provides a folding rotor-type unmanned aerial vehicle equipped with armored vehicles. The rotor unmanned aerial vehicle can be compactly folded so that it can be arranged in a small armored vehicle; it can be unfolded quickly and reliably during work; Operators do not need to leave the warehouse or prepare for assembly. The operation process is fast, efficient, concealed and safe.

[0026] The UAV includes a main body 1, four rotor arms 2 and landing gear 10, and each rotor arm 2 realizes its reliable folding and unfolding through a set of hinge mechanism 3 and limit locking mechanism 4. When the UAV is in a folded state, the four rotor arms 2 are in a vertical state, such as figure 1 As shown; when the UAV is fully deployed, the four rotor arms 2 are in a horizontal state, such as figure 2 shown.

[0027] The main body 1 is a cy...

Abstract

The invention discloses a folding rotor-type unmanned aerial vehicle. The folding rotor-type unmanned aerial vehicle can be folded compactly and unfolded quickly, so that the application flexibility of the rotor-type unmanned aerial vehicle is enhanced effectively. The unmanned aerial vehicle comprises a main body, four rotor arms and a landing gear, wherein each rotor arm is folded and unfolded reliably through a hinge mechanism and a limiting and locking mechanism. When the unmanned aerial vehicle is in a folded state, the rotor arms are positioned in axial grooves in the main body, a torsion spring in the hinge mechanism is compacted, and a limiting and locking piece is positioned at a locked position under the action of a reset spring. When the rotor arms of the unmanned aerial vehicle are required to be unfolded, the limiting and locking piece is driven to slide through a stirring piece along the circumferential direction of the main body, so that the rotor arms are unlocked; the rotor arms are driven to fall quickly by the torsion spring under the effect of torsional force and are limited in a horizontal state. After the rotor arms are unfolded completely, the stirring piece is released, and the limiting and locking piece is returned to the locked position under the effect of the reset spring, so that the rotor arms in an unfolded state are limited and locked.

Description

technical field [0001] The invention relates to a rotor-type unmanned aerial vehicle, in particular to a foldable rotor-type unmanned aerial vehicle, which belongs to the technical field of aircraft. Background technique [0002] In the war environment under the new situation, the demand for armored vehicles to perceive the battlefield environment continues to increase. By carrying unmanned aerial vehicles, armored vehicles can obtain an unprecedented ability to capture non-direct sight targets. However, armored vehicles have their own advantages and limitations as a platform for unmanned aerial vehicles. Existing unmanned aerial vehicles have certain requirements on the size of the site, whether it is in the process of take-off or recovery, and operators need to go out of the cabin or even get off the vehicle to assemble, launch, and recover the unmanned aerial vehicles; armored vehicles are different from The combat environment of general combat platforms is very harsh; e...
