Decelerating and damping method for unmanned aerial vehicle accidental crashing

Abstract

The invention provides a decelerating and damping method for unmanned aerial vehicle accidental crashing. An unmanned aerial vehicle comprises an unmanned aerial vehicle main body, a first undercarriage, a second undercarriage and a horizontal plate, the horizontal plate is fixedly arranged at the tops of the first undercarriage and the second undercarriage, and the unmanned aerial vehicle main body is mounted on the upper surface of the horizontal plate. The decelerating and damping method comprises the following steps that (1), a decelerating and damping device is mounted on the lower surface of the horizontal plate; (2), a remote controller is manipulated on the ground, and the unmanned aerial vehicle takes off in upper air to conduct normal flying operation; and (3), when the unmannedaerial vehicle is out of control due to improper operation of an operator or failure occurrence, the decelerating and damping device is started. According to the decelerating and damping method, the design is novel, the structure is reasonable, the cost is low, the decelerating and damping device only needs to be additionally arranged on the existing unmanned aerial vehicle, the safety guarantee is provided for the unmanned aerial vehicle, safety and reliability are high, the economic loss of a user of the unmanned aerial vehicle is reduced to the utmost limit, and safety of people and objectsthat are smashed due to crashing of the unmanned aerial vehicle is also achieved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a deceleration and shock absorption method for an accidental fall of an unmanned aerial vehicle. Background technique [0002] At present, UAVs have been more and more widely used, and UAVs have appeared in military reconnaissance, traffic monitoring, agricultural spraying pesticides, forest fire warning and other fields. With the popularization and application of drones, crashes occur from time to time due to subjective and objective reasons such as unskilled control technology, misuse, climate, flight environment, battery power failure, etc. of drone controllers. [0003] At present, the parachute in the UAV protective equipment also plays a certain protective role, but when the above-mentioned subjective and objective conditions of the UAV crash occur when the UAV is flying at low altitude, the parachute cannot be fully deployed due to time and spa...

AI Technical Summary

Problems solved by technology

[0003] At present, the parachute in the UAV protective equipment also plays a certain protective role, but when the above-mentioned subjective and objective conditions of the UAV crash occur when the UAV is flying at low altitude, the parachute cannot be fully deployed due to time and space problems, and it cannot achieve its due effect. protective effect

[0004] Even if there are sufficient time and space conditions to satisfy the full deployment of the parachute, when the falling environment is complex, it will inevitably cause damage to the drone, which will bring economic losses to the drone holder and also damage the ground. people, buildings or other objects
