Specific embodiment
A kind of cargo door opening mechanism of integrated motor pressurized strut, it is characterised in that: including there are two be separately positioned on cabin
The suspension arm 2 of the door left and right sides, 2 top of suspension arm are articulated and connected by support 7 and airframe structure, lower part and 1 one end of lower link
Articulated connection, 1 other end of lower link are articulated and connected in hatch door opening stage and cabin door structure；Two suspension arms 2 and fitted shaft 6 are cut with scissors
It connects in succession, electric machine assembly 4 is articulated and connected by support 8 and airframe structure, and pressurized strut 5 is fixedly connected with fitted shaft 6, passes through actuation
The stretching or retraction of cylinder 5, band movable coordinate axle 6 moves, so that two suspension arms 2 be driven to move synchronously；3 one end of upper connecting rod with match
Sympodium 6 is fixedly connected, and the other end is articulated and connected in hatch door opening stage and cabin door structure；Upper connecting rod 3, lower link 1, two suspensions
Arm 2 and cabin door structure form a set of four-bar mechanism.
The upper connecting rod 3 is two, is arranged at 6 both ends of fitted shaft, the near position that connects with suspension arm 2.
The thickness maximum of the suspension arm 2 at an upper portion thereof, is connected with fitted shaft 6, will be connected on two by fitted shaft 6
Bar 3 links together, and realizes the relative rotary motion of suspension arm 2 and upper connecting rod 3.
More specifically, upper connecting rod 3 is connect with hoisting mechanism with lower link 1, in hatch door opening stage, hoisting mechanism with
Cabin door structure locks together, thus lower link 1 and upper connecting rod 3 can be regarded as in opening stage it is hinged with hatch door.
A method of realizing that hatch door opens and closes using cargo door opening mechanism, it is characterised in that:
1, support 7 is connected into airframe structure by being hingedly connected to 2 top of suspension arm, 7 other end of support；Lower link 1 is logical
It crosses and is hingedly connected to 2 lower part of suspension arm, 1 other end of lower link connection hoisting mechanism is considered as herein in hatch door opening stage
It is articulated and connected with cabin door structure；
2,6 both ends of fitted shaft are inserted into suspension arm 2, fitted shaft 6 drives movement by the pressurized strut 5 on electric machine assembly 4；
Upper connecting rod 3 fixed in fitted shaft 6 is connected into hoisting mechanism, in hatch door opening stage, is considered as cutting with scissors with cabin door structure herein
It connects in succession；
3, by electric machine assembly 4, pressurized strut 5 is ejected, flips outward hatch door under the drive of suspension arm 2 and opens,
Opposite fuselage moves downward under the drive of upper connecting rod 3 simultaneously；
4, by electric machine assembly 4, retract pressurized strut 5, making hatch door at this time, inwardly overturning is closed under the drive of suspension arm 2,
Opposite fuselage moves upwards under the drive of upper connecting rod 3 simultaneously.
When specifically used:
Electric machine assembly 4 is articulated and connected by support 8 and airframe structure, and suspension arm 2 is hinged with main body mechanism by support 7
Connection, after electric machine assembly 4 drives pressurized strut 5 to extend, the angle between 2 top half of suspension arm and pressurized strut 5 constantly becomes smaller.Cause
It is to be fixedly connected for pressurized strut 5, fitted shaft 6 and upper connecting rod 3, mutual angle is constant, so upper connecting rod 3 and 2 upper half of suspension arm
Angle between part constantly becomes larger, that is, upper connecting rod 3 is rotated down with respect to suspension arm 2.Upper connecting rod 3 and lower link 1 are in cabin
It is considered that being articulated and connected with cabin door structure, lower link 1, upper connecting rod 3, suspension arm 2 and cabin door structure can in door opening procedure
To regard a set of four-bar mechanism as, thus in hatch door switching process, it can be under the drive of upper connecting rod 3, opposite suspension arm 2 is transported downwards
It is dynamic.
For half blocking type hatch door, after hatch door is promoted, positioned at the upper outside of fuselage opening.Hatch door is opened in overturning
In the process, it is easy to the case where cabin door structure and exterior fuselage skin interference occur.This set mechanism is opened in addition to driving hatch door overturning
Outside, moving downward with respect to suspension arm 2 in hatch door overturning opening procedure is also achieved, this is efficiently solved in hatch door switching process
The problem of interfering with airframe structure.
