Unmanned aerial vehicle with automatic return flight system

Abstract

The invention discloses an unmanned aerial vehicle with an automatic return flight system. The unmanned aerial vehicle with the automatic return flight system comprises an unmanned aerial vehicle shell. The unmanned aerial vehicle with the automatic return flight system is characterized in that an installation hole is formed in the outer wall of the top end of the unmanned aerial vehicle shell, and a return flight mechanism is arranged in the installation hole; the return flight mechanism comprises a plastic shell, and the plastic shell is fixed to the inner wall of the installation hole through bolts; a rectangular hole is formed in the outer wall of the top end of the plastic shell; transverse plates are clamped to both sides of the inner wall of the rectangular hole; and connecting blocks are arranged in the outer walls of the bottom ends of the two transverse plates; and spring pieces are fixed to the outer walls of the opposite side of the two connecting blocks through bolts, theopposite ends of the two spring pieces are separately fixed to the inner walls of the two sides of the plastic shell through bolts, and a metal sleeve is fixed to the outer wall of one side of the plastic shell through bolts. The unmanned aerial vehicle with the automatic return flight system facilitates rapid unfolding of parachutes, improves unfolding success rate, better protects the unmanned aerial vehicle, is safer, reduces losses, has fast trigger response and is convenient to recover, and the operation state of the unmanned aerial vehicle can be conveniently detected.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with an automatic return system. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wi...

AI Technical Summary

Problems solved by technology

Most of the existing drones have an automatic return system. The existing drones are prone to insufficient power and lack of fault protection when they automatically return. Therefore, a drone with an automatic return system is now proposed.
