5 have two output terminals, and two output terminals are hinged with first stage rotation between inner wing 1 and the end face lower part of outer wing 6 respectively
Secondary and second stage revolute pair；Said structure forms double-strand chain revolving structure, can effectively avoid folding rotating shaft protrusion machine
The situation of wing surface, ensures that the wing faying face after expansion is smooth, reduces aerodynamic drag in flight course.
As in preferred embodiments of the present invention, the first revolute pair includes first be connected with folding 5 output terminal of actuator
Stage driving lever 11, the free end of first stage driving lever 11 are hinged with the first rocking arm 10；Under first rocking arm 10 and 1 end face of inner wing
Portion is hinged.
As in preferred embodiments of the present invention, the second revolute pair includes second be connected with folding 5 output terminal of actuator
Stage driving lever 8, the free end of second stage driving lever 8 are hinged with the second rocking arm 7；Second rocking arm 7 is cut with scissors with 6 end face lower part of outer wing
Connect.
A kind of 4 mechanism of lid based on aircraft wing fold mechanism includes being arranged at the lid 4 for folding the top of actuator 5；
Folding the middle part of actuator 5 has external part 9, and the revolute pair for promoting lid 4 to be opened and closed is hinged between external part 9 and lid 4；
The driving of lid 4 is by the way of linkage, it is not necessary to uses special actuator, functional reliability is high, while reduces folding
The overall weight of system；While folding the completion first stage wing-folding of actuator 5, drive lid 4 to overturn, realize servo-actuated fortune
Dynamic requirement, while solve clearance issues and lid 4 and the interference problem of inner wing 1 between outer wing 6 and inner wing 1, using linkage
Mode, avoid using unnecessary actuator, have the characteristics that simple in structure, reliability is high, light-weight.
As in preferred embodiments of the present invention, revolute pair includes the connecting rod hinged with folding 5 external part of actuator, 9 one end

Actuator 5 is folded when driving lever 11 rotates clockwise in the first stage, second stage driving lever 8 does not rotate, and keeps
Second stage driving lever 8 and the relative position of the second rocking arm 7 are constant, and first stage driving lever 11 drives the first rocking arm 10, around interior
Rotated counterclockwise along hinged end under the wing 1, realize that fold actuator 5 rotates counterclockwise on inner wing 1 along hinged end, outer wing 6 and folding
Rotation between folded actuator 5 is lockable, and at this time, outer wing 6 is synchronous with folding actuator 5 counterclockwise along hinged end on inner wing 1
Rotate；Due to folding the rotation counterclockwise of actuator 5, fold 5 external part 9 of actuator by connecting rod 3 drive ear type rocking arm 2 and
Lid 4, is rotated counterclockwise around fixed hinge end, so as to fulfill the servo-actuated of lid 4.When first stage driving lever 11 and first
When rocking arm 10 moves to same straight line, the rotated counterclockwise by angle of first stage driving lever 11 reaches maximum, and the first stage folds
Complete, while servo-actuated lid 4 reaches maximum flip angle；
Start second stage to fold, first stage driving lever 11 does not rotate, and keeps first stage driving lever 11 to shake with first
The relative position of arm 10 is constant, and inner wing 1 and the rotation folded between actuator 5 are lockable, and folds 5 second stage of actuator actively
When bar 8 rotates counterclockwise, second stage driving lever 8 drives the second rocking arm 7 to be rotated under outer wing 6 along hinged end, at this time, outer wing 6
Rotated counterclockwise on outer wing 6 along hinged end.When 8 and second rocking arm 7 of second stage driving lever moves to same straight line, wing
Folding reaches maximum flip angle.
The present invention replaces single swing hinge and two groups of four-bar mechanisms to realize wing double-strand chain with dual AC power hinge
The folding in two stages, using the dead-centre position of mechanism, realizes that wing is held in the good of folding position；With one group of four-bar mechanism
Realize the linkage effect of lid 4, reliability has higher guarantee.
