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 bearing 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 are cut with scissors with fitted shaft 6
It connects in succession, electric machine assembly 4 is articulated and connected by bearing 8 and airframe structure, and pressurized strut 5 is fixedly connected with fitted shaft 6, passes through start
The stretching or retraction of cylinder 5, band movable coordinate axle 6 moves, so as to which two suspension arms 2 be driven to be synchronized with the movement；3 one end of upper connecting rod is with matching somebody with somebody
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, 6 both ends of fitted shaft is arranged on, at 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 by fitted shaft 6 on two
Bar 3 links together, and realizes suspension arm 2 and the relative rotary motion of upper connecting rod 3.
More specifically, upper connecting rod 3 is connected with lower link 1 with hoisting mechanism, in hatch door opening stage, hoisting mechanism with
Cabin door structure locks together, so lower link 1 and upper connecting rod 3 can be regarded as being hinged with hatch door in opening stage.
A kind of method that hatch door folding is realized using cargo door opening mechanism, it is characterised in that：
1st, by bearing 7 by being hingedly connected to 2 top of suspension arm, 7 other end of bearing connection airframe structure；Lower link 1 passes through hinge
It is connected on 2 lower part of suspension arm in succession, 1 other end of lower link connection hoisting mechanism in hatch door opening stage, is considered as and cabin herein
Door is articulated and connected；
2nd, 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；It will match somebody with somebody
Fixed upper connecting rod 3 connects hoisting mechanism on sympodium 6, in hatch door opening stage, is considered as hingedly connecting with cabin door structure herein
It connects；
3rd, by electric machine assembly 4, action barrel 5 is ejected, hatch door is made to be flipped outward under the drive of suspension arm 2 at this time and is opened, simultaneously
Opposite fuselage moves downward under the drive of upper connecting rod 3；
4th, by electric machine assembly 4, action barrel 5 is made to retract, making hatch door at this time, inwardly overturning is closed under the drive of suspension arm 2, simultaneously
Opposite fuselage moves upwards under the drive of upper connecting rod 3.
When specifically used：
Electric machine assembly 4 is articulated and connected by bearing 8 and airframe structure, and suspension arm 2 is articulated and connected with main body mechanism by bearing 7,
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.Because make
With connecting rod 3 to be fixedly connected, mutual angle is constant for dynamic cylinder 5, fitted shaft 6, so upper connecting rod 3 divides it with 2 first half of suspension arm
Between angle constantly become larger, that is, upper connecting rod 3 is rotated down with respect to suspension arm 2.Upper connecting rod 3 is opened with lower link 1 in hatch door
In the process 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 be regarded as
A set of four-bar mechanism so in hatch door switching process, can move downward under the drive of upper connecting rod 3 with respect to suspension arm 2.
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 cabin door structure and the situation of exterior fuselage skin interference occur.This set mechanism is opened except 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.
