Title:
ANTI-CRASH ROTOR WING GUIDE RAIL DEVICE FOR TANDEM DUAL-ROTOR WING UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/045724
Kind Code:
A1
Abstract:
An anti-crash rotor wing guide rail device for a tandem dual-rotor wing unmanned aerial vehicle, comprising a main beam (1), a rotor wing structure, a rotor wing guide rail device, a self-locking device (2), and a sensing device. The rotor wing guide rail device is a horizontal guide rail and a vertical guide rail arranged on an inner wall of the main beam, and a guide rail electromagnetic turning switch (11) is arranged between the horizontal guide rail and the vertical guide rail. The rotor wing structure is distributed at front and rear ends of the main beam by means of the rotor wing guide rail device. A rotor wing base is mounted on the rotor wing guide rail device, moves horizontally or vertically along the rotor wing guide rail device, and is locked by the self-locking device. The anti-crash rotor wing guide rail device may not only be applied to the prevention of crashes caused by a rotor wing failure of an unmanned aerial vehicle, but may also be applied to severe weather, such as typhoons and other extremely unfavorable environments for flight. By means of adjusting the rotor wing position to change a force applied to the unmanned aerial vehicle, balance can be achieved.
