A possibility that, effectively increase the success rate of parachute-opening.In addition, umbrella hatchcover and unmanned plane body are inseparable, parachute-opening dress is increased
The reusability set, and reduce use cost.
According to some embodiments, umbrella hatchcover is a part of the covering 1 of unmanned plane, and locking mechanism 3 is set to unmanned plane
The inside of covering 1, when umbrella hatchcover is closed, umbrella hatchcover is smoothly connected with unmanned plane body.Setting in this way, umbrella hatchcover and machine
The radian being smoothly connected is formd between body profile, can guarantee the aerodynamic characteristic of unmanned plane to greatest extent.
According to some embodiments, which further includes multiple articulated structures 2, further as shown in Fig. 2, the first lid
4 and second lid 6 it is hinged by one or more pin shafts 21 between the side of its expansion and the covering 1 of unmanned plane respectively.Example
Such as, to improve hinged stability, the number of pin shaft 21 used can be two between each lid and unmanned plane covering 1
It is a.
Further, it is provided with torsional spring on pin shaft 21, for example, torsional spring can be fixed in the detent slot at pin shaft 21.Umbrella
When hatchcover is closed, torsional spring generates elastic deformation；When locking mechanism 3 unlocks state to open umbrella hatchcover, torsional spring is in elastic force
Under the action of assist the first lid 4 or the second lid 6 to be unfolded.
Torsional spring at pin shaft 21 in a relaxed state when torsional spring arm between angle can be designed specifically according to specific fuselage shape
Angle number, it is preferable that 1 surface of covering of the first lid 4 or the second lid 6 and unmanned plane is formed when should ensure that torsional spring relaxed state
Angle greater than 90 degree.
The embodiments of the present invention by above-mentioned design so that the first lid 4 and 6 component of the second lid are acted in torsional spring
Under when fully opening in shape is upwarped, reduce the coverage that umbrella hatchcover after parachute-opening is open to umbrella cabin, more conducively parachute is smoothly detached from
Umbrella cabin, and reduce a possibility that parachute is wound with body.
According to some embodiments, with further reference to Fig. 3 a and Fig. 3 b, the first lid 4 is segmentation structure, including first
Part 41, second component 42 and third member 43；When first lid 4 is unfolded, between the first component 41 and second component 42, second
It is respectively formed certain angle between part 42 and third member 43, to generate front face area in the direction of relative wind.
Second lid 6 and the first lid 4 are symmetrical structure, can similarly generate front face area.
For example, the first component 41, second component 42 and third member 43 can be triangle knot shown in Fig. 2 and Fig. 3 b
Structure, three collectively form the first lid 4 of rectangle.
Preferably, between the first component 41 and second component 42, pass through one between second component 42 and third member 43
Or multiple pin shafts 22 are hingedly；One or more pin shaft 21 is hinged between third member 43 and the covering 1 of unmanned plane.For example, being
Improve hinged stability, the number of pin shaft 22 used can be two between two hinged components.
Further, it is also equipped with torsional spring on pin shaft 22, for example, torsional spring can be fixed in the detent slot at pin shaft 22.
When umbrella hatchcover is opened, the torsional spring at pin shaft 22 makes under the action of elastic force between the first component 41 and second component 42, second
Above-mentioned angle is formed between component 42 and third member 43, to generate front face area in the direction of relative wind.
It also include the setting about pin shaft and torsional spring accordingly on second lid 6.
The embodiments of the present invention are by above-mentioned setting, never complete in umbrella hatchcover as shown in Fig. 3 a, Fig. 3 b and Fig. 4
It is deployed into during being fully deployed, umbrella hatchcover can generate front face area in relative wind direction, and unmanned plane is empty awing
Gas can generate resistance to umbrella hatchcover, to promote 43 segmented of the first component 41, second component 42 and third member of the first lid 4
Expansion (the second lid 6 is similarly), just can guarantee the smooth unlatching of umbrella hatchcover in this way.
According to some embodiments, as shown in Fig. 2, when umbrella hatchcover is closed, only the covering 1 of the first component 41 and unmanned plane it
Between by locking mechanism 3 be connected, to lock the first lid 4；The lock mode of second lid 6 is identical as the first lid 4.It is preferred that
Ground, locking mechanism 3 include the first sticking department and the second sticking department, and the first sticking department and the second sticking department structure are identical, use respectively
