Parachute opening buffer mechanism of parachute landing unmanned aerial vehicle and using method thereof

Abstract

The invention discloses a parachute opening buffer mechanism of a parachute landing unmanned aerial vehicle and a using method thereof. The parachute opening buffer mechanism comprises the unmanned aerial vehicle; a cover plate groove is formed in the top of the unmanned aerial vehicle, a parachute cabin is arranged in the unmanned aerial vehicle, the cover plate groove is communicated with the parachute cabin, and a cabin cover is hinged to the top of the cover plate groove; a driving assembly used for opening the cabin cover is arranged on the inner wall of the bottom of the cover plate groove, a plurality of first springs are distributed on the inner wall of the bottom of the parachute cabin at equal intervals, the tops of the multiple first springs are fixedly connected with the same moving plate, and the top of the moving plate is fixedly connected with a parachute pack. The parachute is thrown out from above in an upcast opening manner, so that parachute cord is prevented from being wound on the unmanned aerial vehicle under the influence of airflow, and flight accidents of the unmanned aerial vehicle are avoided; the elastic cushion is ejected from the lower portion throughthe second spring while the parachute pack is thrown out, so that a certain buffering is achieved when the unmanned aerial vehicle lands, and the unmanned aerial vehicle is prevented from making direct contact with the ground and being damaged.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a parachute opening buffer mechanism for a parachute unmanned aerial vehicle and a use method thereof. Background technique [0002] Unmanned aircraft is referred to as "drone" for short. In recent years, the application fields of drones have become more and more extensive. Most drones need to ensure that they return to the ground safely and recover the whole machine and airborne equipment after completing their work. At present, the commonly used UAV recovery methods include landing gear landing recovery, net collision recovery, parachute recovery, air cushion landing recovery, etc. [0003] For the way of parachute recovery, the commonly used UAV parachute opening methods are generally divided into upward throwing and downward throwing. Since the parachute is placed in the canopy, after the canopy is opened by the traditional down-throwing parachute, there is ...

AI Technical Summary

Problems solved by technology

Since the parachute is placed in the canopy, after the canopy is opened by the traditional down-throwing parachute, there is a risk of interfering with the parachute rope due to airflow and other reasons, which may easily cause the parachute to be entangled with the body, resulting in a flight accident. Due to the lack of effective buffer components, it will cause the drone to collide with the ground, causing damage to the drone and causing unnecessary losses
