The bottom of air bottle 6 is provided with air bag storehouse 4, and the gas cylinder 6 is fixedly connected by fixed mount 3 with air bag storehouse 4, the high pressure gas
Feed channel 5 is provided between bottle 6 and air bag storehouse 4, the inside of air bag storehouse 4 is provided with multiple gas columns 7 and is in cellular, the air bag storehouse
4 bottom is provided with vent valve 8.
Particularly, the air bag storehouse 4 is carbon fiber structural, and bottom is spherical in ellipse, and expansible is reverse umbrella-type structure,.
Particularly, the gas cylinder 6 can realize that moment inflates to air bag storehouse 4.
Particularly, the vent valve 8 contacts to earth the gas that can discharge in air bag storehouse 4.
Particularly, gas-filled switching tube and electromagnetic switch are additionally provided with described device.
Beneficial effects of the present invention are：
1st, the present invention is designed using inverted umbrella, has the function that parachute after opening, and playing stably center of gravity during landing prevents
The effect of rollover.
2nd, middle the air cushion in air bag storehouse of the invention designs for grid inflation, and resistance is small during landing, wear-resistant.
3rd, buffer unit of the present invention is touching gas bleeder valve, has very high integration, and the small volume of device is in light weight, is touched
Hair is coherent in time, reasonable in design, can meet to land in an emergency when multi-rotor unmanned aerial vehicle meets unusual condition and reclaim the people of protection and drop point
Member and safeguarding of assets.
4th, the recyclable reset Reusability of single unit system of the present invention.
Brief description of the drawings
Fig. 1 is the collapsed state structural representation of the present invention；
Fig. 2 is the open mode structural representation of the present invention.
Embodiment
The present invention is described further below in conjunction with accompanying drawing：
1- unmanned planes in figure, 2- connected units, 3- fixed mounts, 4- air bags storehouse, 5- feed channels, 6- gas cylinders, 7- gas columns, 8-
Vent valve.Embodiment：
The present invention is by unmanned plane 1, connected unit 2, fixed mount 3, air bag storehouse 4, feed channel 5, gas cylinder 6, gas column 7 and deflation
Valve 8 forms；The bottom of the unmanned plane 1 is provided with connected unit 2, and the bottom of the connected unit 2 is provided with gas cylinder 6, the high pressure
The bottom of gas cylinder 6 is provided with air bag storehouse 4, and the gas cylinder 6 is fixedly connected by fixed mount 3 with air bag storehouse 4, the gas cylinder
Feed channel 5 is provided between 6 and air bag storehouse 4, the inside of air bag storehouse 4 is provided with multiple gas columns 7 and is in cellular, the air bag storehouse 4
Bottom be provided with vent valve 8.
The air bag storehouse 4 is carbon fiber structural, and bottom is spherical in ellipse, and expansible is reverse umbrella-type structure,.
The gas cylinder 6 can realize that moment inflates to air bag storehouse 4.
The vent valve 8 contacts to earth the gas that can discharge in air bag storehouse 4.
Gas-filled switching tube and electromagnetic switch are additionally provided with described device.
Unmanned plane " umbrella shape " inflation buffering landing air-cushion device, the device include multiaxis unmanned plane body and the head carried
Equipment.Device connection is arranged on below body, after unlatching, is made up of following critical piece：
1. periphery is folding " umbrella " shape flank
2. it is oval ball-grid air cushion among
3. (stainless steel) gas cylinder for moment inflation
4. control the device of inflating gas cylinder：Gas-filled switching tube and electromagnetic switch.
5. touching switch of losing heart valve.
It is foldable before apparatus of the present invention inflation, because multi-rotor unmanned aerial vehicle oneself requirement is entirely standby in light weight, to air cushion inflation
Profile, size and the weight aspect of device are required for determining design after carrying out strict test.
1. meet emergency, remote control control switch is opened by controllers, starts gas cylinder inflation on body and opens
