Unmanned aerial vehicle equipped with multiple protection devices and control method thereof

Abstract

The invention discloses an unmanned aerial vehicle equipped with multiple protection devices and a control method thereof, and belongs to the technical field of unmanned aerial vehicles. The unmannedaerial vehicle equipped with the multiple protection devices includes a plurality of buffer energy absorbing devices, an airbag device and a parachute device. The connecting position of each rotor anda vehicle body is provided with the corresponding buffer energy absorbing devices, a number of buffer energy absorbing hollow structures are arranged in the buffer energy absorbing devices, the two ends of each buffer energy absorbing device are connected to the corresponding rotor and the vehicle body, and the buffer energy absorbing devices are allocated to generate deformation firstly when theunmanned aerial vehicle is impacted; the airbag device includes at least one airbag and an inflation structure, and the inflation structure is configured to inflate the airbag so as to expand the airbag and wrap task equipment of the unmanned aerial vehicle; and the parachute device includes at least one parachute bag and parachute opening structures, and the parachute opening structures are configured to launch the parachute bags. The unmanned aerial vehicle adopts the triple protection devices including the parachute device, the airbag device and the buffer energy absorbing devices, multiple-stage multi-aspect protection of the unmanned aerial vehicle is carried out, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle equipped with multiple protective devices and a control method thereof. Background technique [0002] UAV is a new type of aircraft, which can carry out some special operations after carrying some professional equipment. Due to its wide application characteristics, multi-rotor drones will inevitably have failures and accidents during use, and they need to be protected in a targeted manner to reduce losses. [0003] The existing multi-rotor UAV has a single safety protection device, limited functions and safety protection effects, and has a large volume and weight. For example, the excitation devices of the existing airbags and parachutes are pyrotechnics, which require a special pyrotechnic transport vehicle for transportation, which is inconvenient to carry and assemble; The device can only be disassembled after the heat has dissipat...

AI Technical Summary

Problems solved by technology

[0003] Existing multi-rotor drones have a single safety protection device, limited functions and safety protection effects, and are bulky and heavy

For example, the excitation devices of the existing airbags and parachutes are pyrotechnics, which require a special pyrotechnic transport vehicle for transportation, which is inconvenient to carry and assemble; The device can only be disassembled after the heat dissipates, which is inconvenient to operate

Furthermore, the parachute can reduce the speed of the UAV to 5-6m / s at most, and the landing speed is still relatively fast, which will still cause great damage to structures and equipment
