Embodiment 1

[0038] according to figure 1 As shown, an unmanned aerial vehicle of the present embodiment is illustrated, including a fuselage 11, the upper two landing gear arms placed on both sides of the fuselage and the motor installation rod 3, wherein the unmanned aerial vehicle also includes an electric folding mechanism 22. The remote control device (not shown in the figure), the control device for controlling the folding of the electric folding mechanism 22 according to the control signal sent by the remote control device, and the rotating member 4, each of the landing gear arms is connected to the fuselage 11 through the electric folding mechanism 22, The electric folding mechanism 22 is electrically connected with the control device, the control device is placed in the fuselage, and the control device is wirelessly connected with the remote control device; one end of the motor mounting rod 3 is provided with a coaxial first motor 51 and a second motor 51 whose output end is revers...

Embodiment 2

[0042] This embodiment is an optimization made on the basis of Embodiment 1: said each landing gear arm includes a first landing gear arm 211 and a second landing gear arm 212, and one end of the first landing gear arm 211 is connected with the electric folding mechanism 22, The other end is connected to one end of the second landing gear arm 212, wherein the angle between the first landing gear arm 211 and the second landing gear arm 212 is 90-135 degrees. Other structures are the same as in Embodiment 1.

[0043] Since the landing gear arm is divided into two parts, and the angle between the two parts can ensure that the second landing gear arm 212 is stably and reliably parked on the ground when it is lowered, and it can also ensure that the second landing gear arm 212 is retracted. Keep a certain distance from the propellers 111 at both ends of the fuselage 11 to avoid the propellers from being impacted by the second landing gear arm 212 during retraction.

Embodiment 3

[0045] This embodiment is an optimization made on the basis of Embodiment 2: the other end of the first landing gear arm 211 is connected to one end of the second landing gear arm 212 through a rotary buckle structure 24 . Other structures are the same as in Embodiment 2.

[0046] When the UAV is stored, the landing gear arm is retracted by the electric folding mechanism, and then the second landing gear arm is rotated to the inside of the fuselage and snapped into place, so that the storage space of the landing gear arm is further reduced and the space utilization rate is improved. . When the UAV is in use, the second landing gear arm 212 is rotated to the outside of the fuselage until the included angle with the first landing gear arm is 90-135 degrees and then snapped and fixed.

Abstract

The invention provides an unmanned plane (UAV), and relates to an unmanned aircraft. The UAV includes a casing, a fuselage, at least two landing gear arms arranged on both sides of the fuselage and motor mounting rods. The UAV also includes an electric folding mechanism, a remote control device, a control device and a rotating part, the control device controls the electric folding mechanism to fold according to signals sent by the remote control device, the landing gear arms are connected to the fuselage by the electric folding mechanism, one ends of the motor mounting rods are coaxially provided with a first motor and a second motor, output terminals of the first motor and the second motor are reverse, the other ends of the motor mounting rods are fixedly connected with a first end part of the rotating part, and the second end part of the rotating part is movably connected with the fuselage. The UAV is foldable, solves the problem of large occupied space during the UAV overall storage, and is provided with a plurality of motors to ensure the flight stability of the UAV, and at the same time, a landing gear is simple in retractable structure, wide in applicability, and convenient in operation.

Description

technical field [0001] The present invention relates to an aircraft, in particular to an unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicle, unmanned aerial vehicle (UAV) for short, is a new concept aircraft in rapid development, which has the advantages of flexible maneuvering, quick response, unmanned flight, and low operation requirements. UAVs equipped with multiple types of sensors can realize real-time image transmission and detection of high-risk areas, which is a powerful supplement to satellite remote sensing and traditional aerial remote sensing. At present, the scope of use of UAVs has been expanded to the three major fields of military, scientific research, and civilian use, specifically in power, communications, meteorology, agriculture, ocean, exploration, photography, disaster prevention and reduction, crop production estimation, anti-drug anti-smuggling, border patrol, Public security anti-terrorism and other fields are widely use...
