Portable small unmanned aerial vehicle

Abstract

The invention discloses a portable small unmanned aerial vehicle which comprises an unmanned aerial vehicle body and a directional remote handle. Four corners of the unmanned aerial vehicle body are provided with vehicle arm connectors which are tightly welded to the unmanned aerial vehicle body, the ends of the vehicle arm connectors are provided with connecting arms and propellers, and the connecting arms are embedded into the vehicle arm connectors; the propellers are movably connected with the connecting arms through screws, and one ends of the connecting arms are provided with symmetrical storage batteries; an ultrasonic generator is applied so that the distance between the unmanned aerial vehicle and a barrier can be judged through ultrasonic waves, and the application range and the user group of a remote controller receiver can be enlarged; by using a solar electricity generating board, solar energy can be converted into electric energy to be transmitted to the storage batteries, so that a power supply is supplied to flight of the unmanned aerial vehicle, long-time flight of the unmanned aerial vehicle is facilitated, and energy saving is facilitated; and meanwhile, landing supporting feet are applied so that the unmanned aerial vehicle can land whenever and wherever possible.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a convenient small unmanned aerial vehicle. Background technique [0002] UAVs first appeared in the 1920s. In 1914, the First World War was in full swing. The two generals of the United Kingdom, Carder and Pitcher, made a suggestion to the British Military Aeronautical Society: develop a drone that does not use drones. It is a small aircraft piloted by humans and controlled by radio, so that it can fly over a certain target area of ​​​​the enemy and drop the bombs loaded on the small aircraft in advance. In order to deal with the threat of increasing ground air defense firepower, many advanced stealth technologies are applied to the development of UAVs. [0003] The current convenient small UAVs, although there are many types of UAVs, have a single function, and their flexibility of use is much worse than that of helicopters. There is no ultrasonic generator, a...

Problems solved by technology

[0005] The purpose of the present invention is to provide a convenient small unmanned aerial vehicle to solve the above-mentioned background technology, but its use flexibility is much worse than that of a helicopter, and the distance between the unmanned aerial vehicle and obstacles cannot be judged by ultrasonic waves. There is a problem with solar power panels providing power to the drone body
