Technical Field

The invention relates to the field of unmanned aerial vehicles, in particular to a parachute device and an aluminum multi-axis unmanned aerial vehicle.

Background

The pilotless airplane is an unmanned airplane which is operated by radio remote control and remote measuring equipment and a self-contained program control device. The airplane is not provided with a cockpit, but is provided with a navigation flight control system, a program control device, power, a power supply and other equipment. The personnel of the ground remote control and telemetry station can track, position, remotely control, telemeter and digitally transmit the personnel through a data chain and other equipment. Compared with manned aircraft, it has the characteristics of small volume, low cost, convenient use and adaptation to various flight environment requirements, so that it can be extensively used in aerial remote sensing, meteorological research, agricultural flying and pest control, in particular, it has special advantages in war, and can be extensively used for aerial reconnaissance, monitoring, communication, anti-diving and electronic interference, etc.

In modern life, multi-axis unmanned aerial vehicles are known and loved by more and more people, and various multi-axis unmanned aerial vehicles emerge endlessly. But because the various reasons of technique or multiaxis unmanned aerial vehicle itself, still there is multiaxis unmanned aerial vehicle out of control in flight, the unable normal condition that flies to descend, causes a series of troubles, and the fuselage damages that falls. Thus, the existing solution is to install parachute devices on top of the multi-axis drone. However, the parachute line of the parachute device is excessively long, and the solution is liable to cause the parachute line to be entangled with the propeller. Therefore, the existing parachute apparatus has room for further improvement.

Disclosure of Invention

Accordingly, an object of the present invention is to provide a parachute device having an advantage that a parachute line and a propeller are not easily entangled. In addition, still provide an aluminium system multiaxis unmanned aerial vehicle who has this parachute device.

The utility model provides a parachute device includes aerator, gasbag, the parachute body, gasbag and aerator intercommunication, the surface of gasbag is equipped with two readily releasable connecting pieces, when the gasbag was not aerifyd, two the connecting piece is connected in order to form a receiving space at the surface of gasbag, the parachute body is placed at receiving space and its parachute cord is fixed on the gasbag.

Compared with the prior art, the parachute device of the invention inflates the air bag through the inflator, and when the parachute device is initially inflated, the two connecting pieces are still connected, and the parachute body is still in the accommodating space. As the air bag is gradually inflated, the air bag sends the parachute body away from the propeller. When the air bag is expanded enough to separate the two connecting pieces, the two connecting pieces are separated, and the air bag ejects the parachute body from the accommodating space. Finally, under the effect of wind, the parachute body is opened automatically, slows down unmanned aerial vehicle. The parachute device provided by the invention opens the air bag and then opens the parachute body, and the air bag is utilized to correct the flight form of the unmanned aerial vehicle to a certain extent, so that the parachute rope of the parachute body is prevented from being wound with the propeller. And the distance between the parachute body and the propeller is prolonged through the air bag, so that the parachute rope of the parachute body is further prevented from being wound with the propeller. And finally, the parachute body is ejected out by utilizing the air bag, the initial speed of the parachute body is increased, the distance between the parachute body and the propeller is further increased, and the parachute rope of the parachute body is favorably prevented from being wound with the propeller.

Furthermore, the two connecting pieces are magic tapes.

Furthermore, the two connecting pieces are hidden buttons.

Further, the parachute body is located at the most distal end of the airbag from the inflator.

By adopting the technical scheme, the size of the air bag is reduced, and the cost is reduced.

Further, the inflator comprises a shell, an inflating agent and an igniter, wherein an inflating hole communicated with the air bag is formed in the shell, the inflating agent is installed inside the shell, the inflating agent is heated and decomposed to generate gas, and the igniter is arranged inside the shell.

By adopting the technical scheme, the igniter is ignited to generate heat, the inflating agent is heated and decomposed to generate gas, the air bag can be rapidly inflated, on one hand, the parachute body can be rapidly started, and on the other hand, the initial speed of the parachute body can be increased.

Further, still include the storehouse body, cang gai, the storehouse body is for having an open-ended casing, the parachute body, gasbag, aerator are all installed in the storehouse body, cang gai one end articulates on the storehouse body, and the other end and storehouse body joint are in order to close the opening in the storehouse body.

Adopt above-mentioned technical scheme, the parachute device of being convenient for installs on unmanned aerial vehicle, and is applicable to current unmanned aerial vehicle.

The aluminum multi-axis unmanned aerial vehicle comprises a machine body, a main controller and a propeller, wherein the main controller and the propeller are arranged on the machine body, and the aluminum multi-axis unmanned aerial vehicle also comprises a parachute device, the parachute device is installed on the machine body, and the inflator is electrically connected with the main controller.

Compared with the prior art, the aluminum multi-axis unmanned aerial vehicle disclosed by the invention has the advantages that the air bag is inflated by controlling the inflator through the main controller, and the air bag sends the parachute body to a position far away from the propeller. Along with the gas increase in the gasbag, the closed export is opened, and the gasbag pops out the parachute body from the export, and the parachute body is opened, slows down unmanned aerial vehicle. The parachute device provided by the invention opens the air bag and then opens the parachute body, and the air bag is utilized to correct the flight form of the unmanned aerial vehicle to a certain extent, so that the parachute rope of the parachute body is prevented from being wound with the propeller. And the distance between the parachute body and the propeller is prolonged through the air bag, so that the parachute rope of the parachute body is further prevented from being wound with the propeller. And finally, the parachute body is ejected out by utilizing the air bag, the initial speed of the parachute body is increased, the distance between the parachute body and the propeller is further increased, and the parachute rope of the parachute body is favorably prevented from being wound with the propeller.

Further, the parachute device is arranged at the top of the machine body, and the air bag is unfolded towards the upper part of the machine body.

By adopting the technical scheme, the winding of the parachute rope and the propeller of the parachute body can be avoided.

Further, the bottom of organism is equipped with the undercarriage, the parachute device is all installed to the both sides of undercarriage, the gasbag expandes to the outside of organism, after the expansion the gasbag supports in the organism bottom surface mutually and can wrap up organism and screw.

Adopt above-mentioned technical scheme, the parachute body holds up unmanned aerial vehicle through the gasbag, helps unmanned aerial vehicle to slow down, also helps avoiding the parachute line and the screw winding of the parachute body. And organism and screw are wrapped up in to the gasbag after the expansion, help reducing ground to unmanned aerial vehicle's harm.

Furthermore, the air bag type aircraft further comprises a protection frame fixed on the aircraft body, the protection frame is arranged outside the propeller and below the propeller, and the air bag after being unfolded abuts against the bottom surface of the aircraft body and the bottom surface of the protection frame.

By adopting the technical scheme, the air bag is prevented from being damaged by the propeller, and the winding of the parachute rope and the propeller of the parachute body is also prevented.

For a better understanding and practice, the invention is described in detail below with reference to the accompanying drawings.
