Horizontal landing type multi-rotor unmanned aerial vehicle body box

Abstract

The invention relates to the technical field of multi-rotor unmanned aerial vehicles, in particular to a horizontal landing type multi-rotor unmanned aerial vehicle body box. The horizontal landing type multi-rotor unmanned aerial vehicle body box comprises a polygonal unmanned aerial vehicle body shell; an unmanned aerial vehicle body force bearing box and a battery frame are placed in the unmanned aerial vehicle body shell in sequence; an upper opening cover is also arranged at the upper end of the unmanned aerial vehicle body shell; therefore, a distance sensor module detects that the distance between a landing gear and the ground is less than or equal to a set value, each sliding terminal is in contact with the pavement under an effect of gravity and is rearranged in the vertical direction; each rearranged sliding terminal is matched with each concave-convex position on the pavement in a one-to-one corresponding manner; the distance sensor module transmits a detection signal to a control module; and the control module controls a driving unit to prop against and limit the sliding terminals so that the multi-rotor unmanned aerial vehicle lands in a horizontal state. The problem that the multi-rotor unmanned aerial vehicle cannot horizontally land due to complicated road condition in the prior art is solved.

Description

Technical field: [0001] The invention relates to the technical field of multi-rotor drones, in particular to a horizontal landing type multi-rotor drone fuselage box. Background technique: [0002] A multi-rotor UAV is a rotorcraft with more than two rotor axes. Rotated by electric motors at the end of each shaft, the rotors are driven to generate lift. The angle of the rotor is fixed rather than variable like in a helicopter. By changing the relative speed between different rotors, the propulsion torque can be changed, thereby controlling the trajectory of the aircraft. Because multi-rotors are relatively simple and stable, the current implementation of multi-rotor aircraft is much smaller than that of aircraft, so it is suitable for amateur use. Because multicopters are easy to manufacture and control, they are often used to make models and remote-controlled aircraft. The common ones are four-axis, six-axis, and eight-axis aircraft. It is small in size and light in we...

AI Technical Summary

Problems solved by technology

[0005] 1. At present, the shape of the power battery is cubic, and the utilization rate of the space in the spherical or arc-shaped fuselage is not high

[0006] 2. Due to the low utilization rate of the internal space of the fuselage, the installation of airborne equipment is scattered, and many cables are needed to connect the equipment, which increases the weight of the cables

[0007] 3. The fuselage adopts the overall force bearing method of the shell. In order to ensure the rigidity of the fuselage, the fuselage shell is very thick, which increases the structural weight

[0008] 4. In order to install airborne equipment, it is necessary to drill mounting holes on the fuselage shell, which destroys the force transmission route of the shell and reduces the structural strength

[0009] 5. The wetted area of ​​the circular fuselage is too large, which is easily disturbed by gusts of wind, which reduces the safety of the aircraft

[0011] 7. For some multi-rotor UAVs that require high levelness when landing, and some multi-rotor UAVs carry objects, the items loaded have higher requirements for levelness, while the existing multi-rotor UAVs During the landing process, due to different road conditions, the multi-rotor drone cannot land on the ground horizontally
