An unmanned aerial vehicle crash protection device

Abstract

An unmanned aerial vehicle crash protection device is provided, which comprises a fixedly mounted robot arm, an auxiliary rotating paddle wheel, a power impeller, an observation camera, a support bar,and a speed reduction cushioning protection device. One end of the fixedly mounted robot arm is provided with a power paddle wheel and is connected with each other in a rotational manner, and the other end of the fixedly mounted robot arm is connected with the outer surface of the speed reduction cushioning protection device in a bonding manner, and a power paddle wheel is arranged directly in front of the auxiliary rotary paddle wheel. When the unmanned aerial vehicle falls down because of failure, the unmanned aerial vehicle is capable of promptly and accurately ejecting a parachute bag, toincrease the air drag and slow down the falling speed of the UAV, so that the gravity inertia force and impact force of the UAV after falling on the bottom surface are greatly reduced, and then whenthe UAV contacts with the bottom surface, the bottom landing frame can further play the role of cushioning and damping, preventing the components of the UAV from loosening, so as to carry out the protection of the UAV.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, more precisely, it is an unmanned aerial vehicle crash protection device. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by a vehicle-mounted computer. Currently, it is used in aerial photography, agriculture, plant protection, Micro selfie, express transportation, disaster rescue, observing wild animals, monitoring infectious diseases, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, creating romance, etc. However, at present, this drone has the following disadvantages : [0003] 1. When the UAV fails and crashes, the protection measures for the UAV components are not perfect, and the protection cannot be unloaded in time. As a result, the UAV directl...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a UAV crash protection device to solve the problem in the prior art that when the UAV fails and crashes, the protection measures for the UAV components are not perfect, Unable to unload force protection in time, when the UAV falls, due to the large inertial force it receives, it directly collides with the ground causing damage to the UAV, and when the UAV lands on the ground, it produces a large impact force, which is easy to Defects that cause loosening and displacement of internal parts of the drone and affect the function of the drone
