Foldable unmanned aerial vehicle

Abstract

The invention relates to the technical field of design of unmanned aerial vehicles, and particularly relates to a foldable unmanned aerial vehicle. The foldable unmanned aerial vehicle comprises an I-shaped body, a camera platform, battery assemblies, a flight control system, undercarriages, at least four engine arms, propellers and engine arm locking devices, wherein the camera platform is arranged at the bottom side of the head of the body; the battery assemblies and the flight control system are arranged in the body; the undercarriages are uniformly arranged at the bottom of the body in a rotating way; the propellers are provided with driving devices, and one ends of the four engine arms are respectively articulated to four corners of the I-shaped body; and the engine arm locking devices are used for locking the engine arms when the engine arms rotate to a predetermined opening state or a predetermined closing state. According to the foldable unmanned aerial vehicle provided by the invention, when the engine arms rotate to the predetermined closing state, two engine arms positioned at the same side of the body are completely contained in a containing cavity at the side and are locked by the engine arm locking devices, so that the folded unmanned aerial vehicle is compact in structure, relatively small in size and more convenient to carry; and when the foldable unmanned aerial vehicle needs to be used, the foldable unmanned aerial vehicle can be quickly unfolded so as to be in a flight state quickly.

Description

technical field [0001] The invention relates to the technical field of drone design, in particular to a foldable drone. Background technique [0002] Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAVs can carry a variety of loads to complete various complex tasks, and are widely used in many fields such as photography, pesticide spraying, fire prevention and disaster relief, communication, public security and anti-terrorism, and anti-drug and anti-smuggling. [0003] However, the structure design of the UAV described in the prior art is unreasonable, and the structure size is large. Many UAVs adopt a cross-shaped layout, the arms cannot be folded, and most of the electronic devices and battery components are located in the middle of the cross layout. In the cavity, stacked up and down, it takes up a lot of space, making it incon...

Problems solved by technology

[0003] However, the structure design of the UAV described in the prior art is unreasonable, and the structure size is large. Many UAVs adopt a cross-shaped layout, the arms cannot be folded, and most of the electronic devices and battery components are located in the middle of the cross layout. In the cavity, stacked up and down, it takes up a lot of space, making it inconvenient to store and carry the whole drone. When going out, it can only be transported with a large-sized backpack or by a car or other tools. Disassembling the parts increases the complexity of the operation. It is easy to have hidden dangers such as poor contact of electrical connectors and unlocked mechanical structures during installation, which reduces the reliability of the drone and is time-consuming and labor-intensive.
