Gas release device and unmanned aerial vehicle

Abstract

The invention provides a gas release device and an unmanned aerial vehicle and relates to the field of landing equipment for aerial vehicles. A gas release mechanism comprises a trigger mechanism, a striker release mechanism and a gas storage cylinder; the striker release mechanism includes a mounting tube that is hollow, a striker component positioned in the mounting tube and a trigger; one end of the mounting tube is provided with a limiter; the trigger is limited between the limiter and the strike end of the striker component; the opening end of the gas storage cylinder is connected to theend, far away from the limiter, of the mounting tube; the opening end right faces the strike end of the striker component; the trigger mechanism is positioned on one side of the striker release mechanism; when the trigger is in non-operating state, the clamp end, far away from the strike end, of the striker component is extended out of the mounting tube and in clamped connection with the trigger mechanism; when the trigger is in operating state, the striker component strikes the opening end, and the clamp end leaves the trigger mechanism. The gas release device herein enables the parachute ejection distance to be enlarged and assembly difficulty to be relieved, and the influence of spring deformation in the prior art upon parachute ejection is avoided.

Description

technical field [0001] The invention relates to the field of landing equipment for aircraft, in particular to a gas releasing device and an unmanned aerial vehicle. Background technique [0002] With the continuous development of science and technology, the application of drones is becoming more and more extensive, especially when used in the sky above the city, it may be caused by the outside world or the drone itself, causing the drone to fall out of control, causing pedestrians on the ground and The safety of other facilities will affect the safety of the drone and cause the drone to be broken. Therefore, in some drone designs, a parachute device is added to prevent the drone from falling. The most commonly used method at present is to use a spring to eject the parachute, use a parachute or other mechanism to compress the spring, and release the compressed spring to eject the parachute. The method of spring triggering the parachute has relatively high requirements on the...

AI Technical Summary

Problems solved by technology

[0004] 1. The mass of the spring is large, resulting in an increase in the overall weight of the drone;

[0005] 2. After the spring is compressed for too long, it will deform, resulting in a decrease
