Abstract

The utility model discloses a kind of ejection hook of unmanned plane, the lower section of unmanned aerial vehicle body is arranged on, it is characterised in that be cavity inside the ejection hook and fuselage cover integrally casting shaping, the ejection hook, the cavity is connected with the inner chamber of fuselage cover；Carbon fiber wire is filled with the cavity of the ejection hook.The fuselage cover and ejection hook are cast using carbon fibre composite.The carbon fiber wire is filled by dispensing and is fixed in the cavity of ejection hook.The utility model launches the fuselage cover integrally casting of hook and aircraft, has attractive appearance, and ejection is not allowed easy fracture or come off when being hooked in by larger external force.

Description

A kind of ejection hook of unmanned plane

Technical field

A kind of the utility model technical field of aircraft design, and in particular to the ejection hook of unmanned plane.

Background technology

With the fast development in unmanned air vehicle technique field, the takeoff and landing mode of unmanned plane is also varied, launches Winged great advantage is：Place is not chosen, can be taken off whenever and wherever possible.The ejection hook of traditional ejecting type unmanned plane uses metal system It is fixed on after cutting into shaping into specific shape or with carbon plate on unmanned plane, this ejection hook is widely used, and makes simple, But it is due to the defect of fixed form, and rubber band gives ejection one larger pulling force of hook again during ejection, ejection hook easily breaks Split or come off from unmanned plane, caused the accident, security reliability is poor.

Utility model content

The utility model is fixed loosely for ejection hook set forth above and fuselage, the problem of easily causing accident, and is ground Study carefully that design is a kind of safe and reliable, the ejection hook of unmanned plane that ejection hook is not allowed easy fracture or come off from unmanned plane.

The utility model solves the technical scheme that its technical problem used：

A kind of ejection hook of unmanned plane, is arranged on the lower section of unmanned aerial vehicle body, it is characterised in that the ejection hook and fuselage It is cavity inside shell integrally casting shaping, the ejection hook, the cavity is connected with the inner chamber of fuselage cover；The ejection hook Cavity in be filled with carbon fiber wire.

Further, the fuselage cover and ejection hook are cast using carbon fibre composite.

Further, the carbon fiber wire is filled by dispensing and is fixed in the cavity of ejection hook.

Referring now to prior art, the utility model apparently has the advantages that：

1st, the fuselage cover integrally casting of ejection hook and aircraft, has attractive appearance, when ejection is hooked in by larger external force Do not allow easy fracture or come off.

2nd, using carbon fiber wire filling in hollow design in ejection hook, cavity, mitigate relative to by ejection hook solid design The weight of unmanned plane, not only ensure that the intensity of ejection hook but also attractive in appearance light.

Brief description of the drawings

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the utility model embodiment front view；

Fig. 2 is the utility model embodiment unmanned plane sectional view；

Fig. 3 is A portions enlarged drawing in Fig. 2.

Wherein：1st, hook is launched, 11, cavity, 2, fuselage, 3, carbon fiber wire.

Embodiment

The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram, Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.

The ejection hook of unmanned plane as shown in Figure 1-Figure 3, is arranged on the lower section of unmanned aerial vehicle body 2, ejection hook 1 and fuselage 2 Shell integrally casting shaping, by metal die reverse mould one-shot forming, the inside of ejection hook 1 is outside cavity 11, cavity 11 and fuselage 2 The inner chamber connection of shell；So fuselage 2 is engaged togather with launching the smooth outer surface of hook 1, and without connection gap, appearance is beautiful See, and the pneumatic property of unmanned plane is good.

In order to mitigate the weight of unmanned plane, unmanned aerial vehicle body 2 and ejection hook 1 are using carbon fibre composite casting Into.

Because the cavity 11 in ejection hook 1 is than narrow, to prevent parts small during assembling from falling into the cavity of ejection hook 1 11 planted agents block cavity 11, the carbon fiber wire 3 of the utility model packing ratio relatively lightweight into cavity 11, and are fixed by dispensing In cavity 11.So carbon fiber wire 3 does not have the weight of the increase ejection hook 1 of too big degree, and adds the strong of ejection hook 1 Degree, ejection hook 1 intensity is big, long lifespan.

It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality With new.The obvious changes or variations extended out by spirit of the present utility model is still in protection of the present utility model Among scope.
