Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments:
It is as shown in Figure 1 the flexible wing spreading device schematic diagram of marmem, as seen from the figure, one kind is closed based on shape memory
The flexible wing spreading device of gold, including it is inner wing wing root 1, fixed inner wing 2, interior spar 3, spring 4, outer spar 5, pulley 6, scalable
Outer wing 7 and shape-memory alloy wire 8；Wherein, the edge of fixed inner wing 2 is arranged in inner wing wing root 1, and fixed inner wing 2 passes through inner wing
Wing root 1 is fixedly mounted on external flight device outer surface；Interior spar 3, spring 4, outer spar 5, pulley 6, scalable outer wing 7 and shape
Memory alloy wire 8 is fixedly installed in inside fixed inner wing 2；Wherein, interior spar 3 is fixedly mounted on the inner side edge of inner wing wing root 1, interior
3 rectangular cross-section structure of spar；Interior spar 3 is mounted on the inside of fixed inner wing 2 perpendicular to inner wing wing root 1；Interior spar 3 and outer wing
Beam 5 is fixedly connected, and 5 sets of outer spar in interior 3 outer wall of spar；The outer wall of interior spar 3 is set with spring 4,4 one end of spring and it is interior cautiously
Root 1 contacts, and one end contacts with outer spar 5, stretched out by resilient support；Pulley 6 is fixedly mounted on one end of outer spar 5；
Scalable outer wing 7 is fixedly connected with pulley 6；The both ends of shape-memory alloy wire 8 are fixed with the both ends of inner wing wing root 1 respectively to be connected
It connects, and covers the outer rim in pulley 6.
Wherein, one end of fixed inner wing 2 is provided with opening, and opening size is corresponding with the lateral dimension of scalable outer wing 7；Outside
Spar 5 is hollow structure, is sleeved on the outer wall of interior spar 3, and can sliding axially along interior spar 3；Pulley 6 is with 5 edge of outer spar
In spar 3 slide axially.
Scalable outer wing 7 can be with the sliding axially along interior spar 3 of pulley 6, and stretches out or shrink in fixed inner wing 2 one
The opening at end.
Shape-memory alloy wire 8 rises with temperature and is shunk, and pulling outer spar 5, inwardly cautiously 1 direction of root is shunk, by giving
The power-up of shape-memory alloy wire 8 rises 8 temperature of shape-memory alloy wire, realizes the extension and contraction control to scalable outer wing 7.
