Unmanned aerial vehicle with telescopic vehicle arms changing into rotor wings

Abstract

The invention provides an unmanned aerial vehicle with telescopic vehicle arms changing into rotor wings. The unmanned aerial vehicle comprises an inner vehicle arm and an outer vehicle arm nested onthe inner vehicle arm, a rack is arranged at one end of the inner vehicle arm, the end, provided with the rack, of the inner vehicle arm penetrates through the outer vehicle arm to extend into a cavity of the vehicle body, rectangular holes are formed in the top of the cavity, a spiral gear-rack driving motor is mounted on the outer wall of the top of the cavity, and spiral teeth of the spiral gear-rack driving motor are meshed with racks of the inner vehicle arm through the rectangular holes; a steering engine is fixed to the other end of the inner vehicle arm through a bolt, a rudder arm isarranged on the steering engine, a propeller driving motor is installed on the rudder arm, and a propeller is installed on the propeller driving motor; a microprocessor and a lithium-sulfur battery are both installed in the vehicle body, and a wireless signal transceiver is installed at the top of the vehicle body. The flight attitude of the unmanned aerial vehicle can be flexibly changed, and thevehicle body is compact in overall structure and convenient to fold and carry.

Description

Technical field: [0001] The present invention relates to the field of unmanned aerial vehicles. Background technique: [0002] With the development of society and the advancement of science and technology, automatic non-chemical technology has gradually been applied to the field of aircraft, and drones have emerged as the times require. The full name of man-machine is unmanned aircraft, which is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. Compared with manned aircraft, unmanned aerial vehicles have the advantages of small size, low cost, and convenient use. UAVs are widely used in fields such as plant protection, street view shooting, power inspection, environmental protection, and post-disaster rescue. Compared with fixed-wing drones, foldable, compact, and portable rotorcraft are usually the current development trend. However, most of the fixed-wing UAVs in the prior art are not scalable, and their flexibi...
