Example can be realized, when rotating shaft 2 rotates, drive arc rocker arm assembly 7 to rotate, so as to drive pressure port mechanism, realize landing gate
The unlatching of pressure release lid.
The embodiment of door ladder unification landing gate two-part curve drive mechanism of the present invention is as follows：When hatch door is opened,
Driving rocker arm assembly 1 rotates, and so as to which the rotating shaft 2 for driving with driving rocker arm assembly 1 to be fixedly connected rotates, rotating shaft 2 drives slot rolling to shake
Arc rocker arm assembly 7 is driven to rotate while arm 3 rotates, arc rocker arm assembly 7 drives landing gate pressure release lid to open；Now roll
The relative movement orbit of wheel 8 is curved section A, because curved section A center overlaps with the axis of rocker shaft 6, elbow rocking arm set
Part 5 does not move in this stage, so as to which landing gate is motionless；When driving rocker arm assembly 1 to be rotated further, continue to drive slot rolling to shake
Arm 3 rotates, and the movement locus of roller 8 is curved section B, drives elbow rocker arm assembly 5 to move, so as to drive the other end of pull bar 4
Landing gate hoisting mechanism, landing gate lifting.Finally realize, first open landing gate pressure release lid, then lift landing gate again
It is required that.Furthermore it is also possible in driving rocker arm assembly 1, the elbow of door of the present invention ladder unification landing gate two-part curve drive mechanism
The inside of rocker arm assembly 5 and the grade of arc rocker arm assembly 7 sets cavity respectively, for mitigating the quality of component.
In summary, in door of the invention ladder unification landing gate two-part curve drive mechanism, elbow rocker arm assembly 5 is with stepping on
The hoisting mechanism connection of gate, arc rocker arm assembly 7 are connected with pressure port mechanism.By designing two-part on slot rolling rocking arm 3
Curve, when the movement locus of roller is when on curved section A, landing gate is motionless, and landing gate pressure release lid is opened；When the motion of roller
When on curved section B, landing gate pressure release lid is maintained at opening, landing gate lifting for track.The mechanism realizes hatch door machine
The functional requirement of structure sequencing action, mechanism design is simple, compact, and arrangement is ingenious, and it is just real not take additional space
Show hatch door mechanism sequentially-operating, add the security reliability of aircraft.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, the change or replacement that can readily occur in, all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should using the scope of the claims as
It is accurate.
