Specific implementation mode
Referring to Fig.1, Fig. 2, Fig. 3, the utility model proposes a kind of unmanned plane parachute novel ejection constructional device, packet
It includes：Body, ejection device, parachute and control system.
Body includes engine base 7, ejection guns 4, ejection lid 1 and bottom plate 6.Bottom plate 6 is mounted on engine base 7, and ejection guns 4 is vertically pacified
On bottom plate 6 and bottom plate 6 is coordinated to form barreled structure.It launches 1 side of lid and is mounted on ejection guns with the hinged overturning of ejection guns 4
On 4 and cover end face of the ejection guns 4 far from bottom plate 6.Specifically, the one end of ejection guns 4 far from bottom plate 6 is equipped with retainer plate 3, ejection
Lid 1 is mounted on retainer plate 3.And ejection guns 4 and retainer plate 3 are used to carry out overturning limit to ejection lid 1 equipped with mutually matched
The structure of position, for example, ejection lid 1 is equipped with the protrusion 9 being generally aligned in the same plane with lid, retainer plate 3 is equipped with respective protrusions 9
The movement locus of springing lid 1 can be limited in outside ejection guns 4, both by groove 10 in this way, by the cooperation of protrusion 9 and groove 10
Ejection guns 4 can be closed by launching lid 1, and ejection guns 4 can be absorbed in avoid ejection lid 1, the work inside ejection guns 4 is made
At influence.
Ejection device 2 is mounted on for being inflated into ejection guns 4 on bottom plate 6 and in ejection guns 4.In ejection guns 4
The pallet 5 for being parallel to bottom plate 6 and being slided along 4 inner wall of ejection guns is installed, pallet 5 is located at one of ejection device 2 far from bottom plate 6
End.Specifically, pallet 5 is barreled structure of the opening towards bottom plate 6, the side wall of pallet 5 is circumferential against 4 inner wall of ejection guns.Landing
Umbrella is placed on pallet 5, and parachute rope is bundled on the circular hole 8 being arranged on engine base 7.
In this way, after the unmanned plane parachute novel ejection constructional device is mounted on unmanned plane, when unmanned plane landing, ejection
The work of device 2 generates gas push pallet 5 and is moved towards ejection lid 1 so that the parachute on pallet 5 push open ejection lid 1 and with
Ejection guns 4 detaches, and after parachute leaves ejection guns 4, unmanned plane continues to land, and parachute is all opened using air drag principle
It opens.
In present embodiment, control system be mounted on engine base 7 on, be separately connected preset gravity accelerometer and
