Description
Technical field
The present invention relates to unmanned plane technical field of aerospace, and in particular to a kind of new unmanned plane umbrella hatchcover automatic opener
Structure.
Background technology
Unmanned plane recovery is broadly divided into running landing and parachuting landing two ways.Running landing is higher to site requirements,
For small and medium size unmanned aerial vehicles, in order to reclaim simplicity, landed and reclaimed using parachuting more.
When being reclaimed using parachuting landing, parachute is generally placed upon in the fuselage deckle board of unmanned plane, is covered with umbrella hatchcover.Work as nothing
Man-machine completion task is, it is necessary to when landing, it is necessary to opens umbrella hatchcover at once and discharges parachute, completes parachute-opening action.Work as unmanned plane
In the task of execution, it is not necessary to during parachute-opening, if umbrella hatchcover is opened, parachute can be caused to open, unmanned plane is crashed；Equally work as nothing
It is man-machine need landing when, if umbrella hatchcover accurately, can not be opened quickly, also result in unmanned plane crash.
Simultaneously because unmanned aerial vehicle body space is limited, the requirement to weight is higher, therefore umbrella hatchcover opener structure is not
Preferably complicated, occupancy volume is small, and functional reliability will height.
Chinese Patent Application No. CN 106184701A disclose a kind of unmanned plane parachute automatic-opening mechanism, by fixing
Bulkhead skeleton in internal body, the umbrella hatchcover that can be upspring automatically, the umbrella cabin for matching with umbrella hatchcover connection, steering wheel, drive shaft,
Steering wheel rocking arm, steering wheel fixed platform composition；Characterized in that, bulkhead skeleton is fixed on internal body, set at the top of bulkhead skeleton
There is steering wheel fixed platform；The side of bulkhead skeleton is provided with umbrella cabin, and the one end in umbrella cabin is flexibly connected one end of umbrella hatchcover, umbrella hatchcover
The other end and the sidepiece joint match of steering wheel fixed platform；Steering wheel is fixed with the inside of steering wheel fixed platform, is set on steering wheel
Drive shaft is connected by steering wheel fixed platform and steering wheel rocking arm.Its good effect is：Make full use of unmanned plane body
Unmanned plane parachute is loaded in inner space, facilitates the filling and unlatching of parachute；Umbrella hatchcover is reduced to greatest extent opens driving machine
Air drag produced by structure.
Unmanned plane parachute automatic-opening mechanism disclosed in document, automatically upspring using having of being matched on unmanned plane umbrella cabin
The umbrella hatchcover of function, to facilitate the filling of parachute and unlatching；When before unmanned plane takes off and flight course in, one end of umbrella hatchcover
(as shown in Figure 1) is suppressed by steering wheel rocking arm, to ensure flight safety；When unmanned plane drops to ground, in steering wheel fixed platform
The steering wheel of installation drives steering wheel rocking arm to stir to the left or in the range of 90 ° of right side by drive shaft, umbrella hatchcover is upspring automatically,
And parachute is opened, help unmanned plane to slow down with realization, the purpose of safe falling.The drive mechanism opened as umbrella hatchcover
Steering wheel, in unmanned plane body, only steering wheel rocking arm is exposed, and air produced by can reducing the part to greatest extent hinders
Power.
It is not difficult to find out, unmanned plane parachute automatic-opening mechanism has the following disadvantages disclosed in document：
First, need that a steering wheel is installed, add the unstability of mechanism operation；
2nd, the rocking arm at the top of steering wheel is during unmanned plane during flying, it is possible to occurs trembling due to caused in aircraft flight
It is dynamic to wait other situations, cause rocking arm to loosen, self falling so that umbrella hatchcover opens voluntarily, to add risk；
3rd, steering wheel rocking arm is only used only and pins umbrella hatchcover, and the matching for opening mechanism and the locking device certainly of umbrella hatchcover
Do not illustrate, matching is still to be tested.

4, the original state of stage clip 4 is compressive state；Control board 7 in the Electromagnetic lock component 13 receives outside cut-offing instruction
Powered off, the current vanishes of coil 10, magnetic field caused by electric current disappears simultaneously, and magnetic attraction caused by silicon steel sheet 9 disappears, silicon
Magnetic force is disappeared between steel disc 9 and suction iron iron plate 8, and umbrella hatchcover 3 is quickly opened in the presence of stage clip 4, discharges extractor parachute and drop
Fall umbrella, complete parachute-opening.
The present invention further technical scheme be：The umbrella hatchcover 3 and unmanned machine frame 12 are be hinged, when umbrella hatchcover 3 is beaten
When opening, under airflow function, umbrella hatchcover 3 is that circumferentially shape starts in axle center with hinge 14, and pulls out extractor parachute and parachute.
The present invention further technical scheme be：The top installation Electromagnetic lock component 13 of the mounting bracket 1, caused by it
Magnetic force tightly holds the suction iron iron plate 8 on umbrella hatchcover 3, reaches the purpose for pinning umbrella hatchcover.
Invention effect
The technical effects of the invention are that：Compact-sized, small volume of the invention, has been effectively saved fuselage space；Utilize
Magnetic adhesion caused by electromagnet tightly pins umbrella hatchcover, it is necessary to during parachute-opening, and flight control computer sends signal, cuts off the electricity supply,
Magnetic adhesion disappears, and stage clip plays a role, while under airflow function, can fast and accurately open umbrella hatchcover；The device is installed
Convenient, reliability height.
