A kind of duct type parachute escape device (CN202355711U), comprise lifesaving casing, parachute and pipeline, pipeline is the cylindrical passage that lands that flame-retardant textile is woven into, the spherical safety air bag that is close in together is equipped with in the bottom of pipeline, and the inwall of pipeline is equipped with several choke coils, and parachute is arranged on the entrance place, and can descend along pipeline, during decline, inflated seat cushion edge and the inner-walls of duct of parachute closely pressed close to, and parachute is slowly descended, and personal security skids off in pipeline.The utility model is simple in structure, and volume is little, and is lightweight, easy to operate during presence of fire, and safety performance is good.
Through contrast, the technology of above patent documentation and present patent application exists more different.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of simple in structure, design science, the little quality of volume are light, unmanned plane good buffer effect reclaims shock-absorption air bag.
The utility model solves its technical matters and takes following technical scheme to realize:
a kind of unmanned plane reclaims shock-absorption air bag, comprise fuselage, wing and air bag buffer, be fixed with wing on fuselage, it is characterized in that: on described fuselage, air bag buffer is installed, this air bag buffer comprises storage case, the air inlet and outlet piping, supply fan and air bag, its concrete structure is for being fixed with the storage case of a lower ending opening on wing, one air inlet and outlet piping is installed between this storage case and fuselage, one end of this air inlet and outlet piping connects a supply fan that is packed on fuselage, the other end of this air inlet and outlet piping stretches in storage case and is sealedly connected with an air bag that overlays in storage case.
And, described air bag buffer symmetry be arranged in fuselage or wing on.
Advantage of the present utility model and good effect are:
1, the utility model adopts the damping modes of air sac to carry out, simple in structure, design science, the little quality of volume are light, good buffer effect, adopt the air bag of collapsible collection as main shock absorption device, because it is lightweight, air bag can be folded into small size and is collected in body before inflation, can not cause flight resistance under sail, and easily realize the little advantages such as deceleration overload, can be applied in widely in multiple unmanned plane damping application.
2, the air bag in the utility model adopts stiff, flexible, inflatable utricule that sir-tight material is made, this air bag buffer not only can absorb and discharge enough impact energys, reduce the UAV Landing impact load, also reach in landing mission simultaneously and rebound phenomenon can not occur, make unmanned plane stablize decline ground connection, safe landing in landing mission.
Description of drawings
Fig. 1 is the utility model air bag collapsed state structural representation;
Fig. 2 is the utility model inflated condition structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
The present embodiment accompanying drawing 1, Fig. 2 have only shown the structure division relevant with the utility model.
A kind of unmanned plane reclaims shock-absorption air bag, comprises fuselage 1, wing 5 and air bag buffer, is fixed with wing on fuselage, and innovative point of the present utility model is:
On described fuselage, air bag buffer is installed, this air bag buffer comprises storage case 4, air inlet and outlet piping 3, supply fan 2 and air bag 6, its concrete structure is for being fixed with the storage case of a lower ending opening on wing or fuselage, one air inlet and outlet piping is installed between this storage case and fuselage, one end of this air inlet and outlet piping connects a supply fan that is packed on fuselage, and the other end of this air inlet and outlet piping stretches in storage case and is sealedly connected with an air bag that overlays in storage case.
The conventional state of described air bag is folding being placed in described storage case, structure shown in Figure 1; When landing was landed, supply fan was inflated in air bag by the air inlet and outlet piping, and this airbag aeration expands and stretched out by the storage case lower ending opening, until reach state as shown in Figure 2, shock absorbing power when UAV Landing guarantees body safety.
