Description

A kind of stealthy unmanned engine room cover locking mechanism of flying wing type layout

Technical field

The present invention relates to unmanned plane fields, and in particular to a kind of flying wing type unmanned engine room cover locking mechanism.

Background technique

General stealthy unmanned plane all has multiple equipment cabin, such as: electronics bay, buffer air bag cabin, rises parachute compartment Fall frame cabin, enging cabin and photoelectric nacelle etc..In flight course, generally as parachute compartment, buffer air bag cabin, landing gear compartment etc. It is that normal open is needed to be closed.Unmanned plane there are many landing modes, the deep red recycling of umbrella be it is one such, landed in unmanned plane Cheng Zhong, parachute compartment need to open with buffer air bag cabin.Parachute and buffer air bag are located inside umbrella cabin, when unmanned plane prepares to drop When falling, parachute compartment and buffer air bag cabin are opened, if cannot quickly and accurately open, will lead to unmanned plane crash.

206971969 U of Chinese Patent Application No. CN discloses a kind of unmanned plane umbrella hatchcover automatic-opening mechanism.The mechanism Using the principle of electric magnetisation, when electric current passes through coil, electromagnetic lock can generate powerful magnetic attraction and iron iron plate is tightly sucked Achieve the effect that lock umbrella hatchcover.After cutting off the power, electromagnetic lock loses magnetic attraction and opens umbrella hatchcover under pressure spring effect.It can be with Find out that this mechanism needs persistently to be powered to coil, therefore more demanding for the power-supply system of unmanned plane.

General stealthy unmanned plane due to the requirement to Stealth Fighter, fuselage surface it is as few as possible there are other devices, because This, is strict with the position of hatchcover locking structure again.

It is very high for junction intensity requirement when general unmanned plane high-speed flight.If intensity not enough will lead to hatchcover and beat It opens, buffer air bag and parachute pop up, and unmanned plane is caused to crash.

Summary of the invention

The present invention is the switch for controlling hatchcover by connecting main latch hook using Servo-controller rocker arm.The advantage of the design is The servomechanism of lockable mechanism is located inside equipment compartment, does not influence the Stealth Fighter of unmanned plane；Unmanned plane in high-speed flight, for Hatchcover lockable mechanism junction intensity requirement is very high, and the design can satisfy the intensity requirement under unmanned plane high-speed flight state.

The technical scheme is that a kind of flying wing type is laid out stealthy unmanned engine room cover locking mechanism, including latch hook cabinet (1), latch hook Box Cover (2), main latch hook (3), secondary latch hook (4), cornual plate (5), lock shaft (6), air bag hatchcover (71), air bag hatchcover (72), umbrella hatchcover (8), torsionspring (9), steel wire (10), tightly plug with molten metal spoke nipple (11), umbrella hatchcover inner clamp (12), air bag Cabin inner clamp (131), air bag cabin inner clamp (132), metal patch (14), Servo-controller (15), power supply system (16), rudder Machine rocker arm (17), Time-optimum Controller (18), plastic straw (19), spring fixed hole position (20).

Further technical solution be latch hook cabinet (1), latch hook Box Cover (2), main latch hook (3), cornual plate (5), lock shaft (6), Torsionspring (9) and the screw (11) for confining steel wire constitute main latch system.Cornual plate is located at air bag cabin or umbrella cabin inner wall, adopts Cornual plate is fixed with adhesive means.The effect of cornual plate is for fixing latch hook cabinet (1), using threaded connection.Latch hook cabinet (1) The connection hole location of upper reserved lock shaft (6), lock shaft guarantee main latch hook (3) for fixing main latch hook (3) and torsionspring (9) It can be axle center rotation with lock shaft (6).The spring coil of torsionspring (3) is fixed on lock shaft (6), and it is pre- that main latch hook is fixed in an end It stays on spring fixed hole position (20), is contacted using end by restraining position of latch hook cabinet (1) bottom.It reserves and prohibits on main latch hook (3) The hole location of spoke nipple (11) is pluged with molten metal, the fixation of fixed traction steel wire (10) is used for.

Further technical solution is steel wire (10), Servo-controller (15), power supply system (16), steering engine rocker arm (17), fast Fast adjuster (18) constitutes the servo-system of lockable mechanism.Steel wire (10) plays connection and draw, plastic straw (19) position Inside cabin and gluing is fixed, for running through steel wire (10).Servo-controller (15) receives to fly control signal control steering engine rocker arm (17) it rotates, steering engine rocker arm (17) connects Time-optimum Controller (18), and Time-optimum Controller (18) connection steel wire controls main latch hook (3) and beats Opening and closing is closed, and realizes the control to latch system.

Further technical solution is secondary latch hook (4), air bag hatchcover (71), air bag hatchcover (72), umbrella hatchcover (8), umbrella cabin Lid inner clamp (12), air bag cabin inner clamp (131), air bag cabin inner clamp (132), metal patch (14) constitute locking The hatchcover latch hook system of mechanism.Air bag hatchcover (71), air bag hatchcover (72), umbrella hatchcover (8), for fixing umbrella hatchcover inner clamp (12), air bag cabin inner clamp (131) and air bag cabin inner clamp (132).Folder on the inside of umbrella hatchcover inner clamp (12), air bag cabin Tool (131) and air bag cabin inner clamp (132) are for limiting and fixing metal patch (14).Metal patch (14) is used for fixed joint Latch hook (4).

Specific embodiment

It is received by servo-system and flies control signal control latch system and open come release cover lock hook system, it is slow to control with this The opening of air-impulse bag hatchcover and parachute hatchcover.

It is the closing process of hatchcover first.Since unmanned plane does not need the closing process of control hatchcover in flight course, Only need to guarantee that hatchcover is opened in not operation in flight course.Therefore the closing of hatchcover of the present invention is not need to watch Dress system control.Hatchcover is pressed by manpower when the closing of hatchcover, contacts secondary latch hook (4) with main latch hook (3), is further pressed So that main latch hook (3) is rotated clockwise to secondary latch hook around lock shaft and cross main latch hook upper surface limit, main latch hook (3) is due to torsion at this time Spring torsion effect, forces main latch hook (3) to rotate counterclockwise around lock shaft, and main latch hook (3) lower surface connects with secondary latch hook (4) upper surface Touching, is reached limit purpose, the closing of hatchcover is controlled with this.

Followed by about the opening procedure of hatchcover.It needs to open in unmanned plane descent and splashes down umbrella hatchcover and buffer air bag Hatchcover.The Servo-controller control steering engine rocker arm rotation control main latch hook of steel wire traction (3) is rotated clockwise to main latch hook (3) and pair is locked Hook (4) is kept completely separate, and hatchcover is separated with cabin by atmospheric action, reach the opening of unmanned plane hatchcover by hatchcover latch hook system Purpose.
