A double-folding-wing full-sealing linkage folding and unfolding mechanism comprises a double-folding deformation wing, a hinge mechanism, a steel wire rope assembly, a 90-degree reverse screw mechanism, a 180-degree reverse screw mechanism and a rope mechanism. The 90-degree reverse screw mechanism is mounted in the middle of the fixed inner wing 1a and the folding middle wing 1b, and is rotationally supported by a middle wing hinge 2a; the 180-degree reverse screw mechanism is mounted in the middle of the folding middle wing 1b and the folding outer wing 1c, and is rotationally supported by an outer wing hinge 2b; the rope mechanism rotates and outputs, an inner wing steel wire rope 3a is pulled to move in a reciprocating mode, a middle wing steel wire rope 3b and an outer wing steel wire rope 3c are in reciprocating linkage, and then a right-handed moving rod 4c, a left-handed moving rod 5c1 and a right-handed moving rod 5c2 are forced to be engaged in a linear variable-rotation rolling mode, so that a folding middle wing 1b rotates by 90 degrees, and a folding outer wing 1c rotates by 180 degrees; the full-unfolding and full-folding effects of the double-folding deformation wing under the conditions of a single driving source and power transmission sealing are achieved.
一种双折叠翼全密封联动折展机构,包括:双折叠变形翼、铰链机构、钢丝绳组件、90°逆螺旋机构、180°逆螺旋机构、绳索机构;90°逆螺旋机构安装于固定内翼1a、折叠中翼1b的中间位置,利用中翼铰链2a进行旋转支承;180°逆螺旋机构安装于、折叠中翼1b、折叠外翼1c的中间位置,利用外翼铰链2b进行旋转支承;绳索机构旋转输出,拉动内翼钢丝绳3a往复移动,并使得中翼钢丝绳3b与外翼钢丝绳3c往复联动,进而迫使右旋移动杆4c、左旋移动杆5c1、右旋移动杆5c2,经过直线变旋转滚动啮合,使得折叠中翼1b转动90°角、折叠外翼1c转动180角;实现双折叠变形翼在单驱动源、动力传递密封条件下全展开与全折叠效果。
