Summary of the invention
The purpose of this invention is to provide a kind of landing cushion gasbag gas filled device that is applicable to the unmanned plane recovery system.
In order to realize above purpose, the technical solution adopted in the present invention is: UAV Landing buffer air bag gas filled device, this device comprises the gas cylinder that extends about the bottle axis, be used for opening after to the charge valve of inflating gas cylinder be used for control to the electromagnetic valve of buffer air bag inflation, the neck of gas cylinder is integrally formed with charge valve mounting interface and electromagnetic valve mounting interface, and described charge valve and electromagnetic valve correspondence are assemblied on the described mounting interface.
Described electromagnetic valve mounting interface is located at the end face of cylinder neck, and the axis of electromagnetic valve is parallel with the axis of gas cylinder or overlap, and is provided with the supporter of supporting electric magnet valve below the electromagnetic valve.
Described charge valve mounting interface is located at the side of cylinder neck, and the axis of charge valve is perpendicular to the axis of gas cylinder.
Be equipped with the electric coupler for access solenoid control signal on the described supporter, electric coupler is electrically connected with electromagnetic valve.
Described gas cylinder and supporter all are fixed on the installation base plate; Described gas cylinder is fixed on the installation base plate by the gas cylinder clip; Described electromagnetic valve is fixed on the supporter by the electromagnetic valve clip.
Described gas cylinder is provided with the restriction axially movable position-limited trough of gas cylinder clip or retaining convex rib.
Described electromagnetic valve is large flow, low voltage opens solenoid valve.
Described gas cylinder is that stainless steel material is made.
Gas cylinder of the present invention adopts integral structure, charge valve mounting interface and electromagnetic valve mounting interface are all processed in cylinder neck, and charge valve and electromagnetic valve correspondence be assemblied on the described mounting interface, has very high integration, reduced the use of pipeline, thereby greatly reduced the volume and weight of device, satisfied the requirement of UAV Landing buffer air bag gas filled device profile, size and weight.
Electric coupler of the present invention is fixed on the supporter, has shortened the length of line of control setup, makes integral structure compacter; Gas cylinder is fixed on the installation base plate, has reduced this device stress to the cabin plate when installing with the engine room zero people plate and concentrated, effectively protected the cabin plate; Be fixed on the installation base plate by the gas cylinder clip on the gas cylinder, can prevent effectively that gas cylinder from rocking, make fixing more firm of gas cylinder; Because it is very short that unmanned plane reclaims the landing time, for satisfying it to the strict demand of gas filled device deflation time, this device adopts large flow solenoid valve, has greatly shortened the inflationtime to buffer air bag, has guaranteed the fiduciary level that reclaims; Unmanned plane generally adopts storage battery, voltage drop after task is finished, and electromagnetic valve is that low voltage is opened in this device, has effectively guaranteed the reliable unlatching of electromagnetic valve in the unmanned plane removal process; Gas cylinder adopts stainless steel material to make, and bearing capacity is strong, in the situation that do not reduce the amount of being filled with that gas cylinder volume has increased gas, the weight of gas cylinder relatively other cast steel gas cylinders itself alleviates greatly, thereby has further alleviated the total weight of this gas filled device.
