Multi-rotor type unmanned aerial vehicle available for adjusting direction of thrust

Abstract

The invention discloses a multi-rotor type unmanned aerial vehicle available for adjusting direction of thrust, which is provided with a battery module, and is used to fly according to commands of a control module used for controlling rotation of a plurality of propellers. The multi-rotor type unmanned aerial vehicle includes: a main body including the battery module and the control module; a plurality of frames connected to a side surface of the main body and extending therefrom; a first motor connected to a distal end of each of the frames; and a drive unit connected to the first motor, wherein the drive unit includes a rotary frame and a stationary frame each having a circular shape and connected to each other in the form of a gyroscope, a second motor supported at the center of the rotatable frame, and a propeller connected to the second motor, and a vector of thrust generated by rotation of the propeller is variable according to rotation of the first and second motors.

Description

technical field [0001] The present invention relates to a tool for controlling the movement of an unmanned aerial vehicle such as a quadrotor, and more specifically, relates to an unmanned aerial vehicle with a driving tool for controlling the thrust direction of a propeller provided on the unmanned aerial vehicle. Background technique [0002] Recently, there has been an increase in the demand and utilization of unmanned aerial vehicles in environments where it is difficult for humans to operate. Unmanned aerial vehicles can perform, for example, acquisition of aerial images in inaccessible disasters or disaster areas, power line detection, or provide enemy hidden information on the battlefield, or perform reconnaissance and surveillance tasks through unmanned aerial vehicles. [0003] As common forms of vertical take-off and landing unmanned remote control aerial vehicles, for example, single-rotor helicopters, coaxial helicopters, quadrotors, and the like can be cited.

Problems solved by technology

[0005] However, the quadrotor has a structure in which the entire fuselage is tilted in the direction of movement when the direction is changed to move, so there is a possibility that the quadrotor will easily fall over due to the wind blowing in the same direction as the direction of movement. When the flight is stopped, it is easily affected by external disturbances such as wind, so that it cannot guarantee a stable flight

[0006] In addition, if the entire quadrotor fuselage is tilted when moving in reverse direction, the cross-sectional area subjected to air resistance becomes larger, so there is a problem that the aerodynamic energy loss increases when moving horizontally.
