Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
As it is shown in figure 1, the elementary cell of collapsible cylindrical reticulated shell is pole scissors unit 1.Each pole scissors unit 1 by
Two poles 2 form, and bending place is at pole 2 midpoint, and dotted line is pole scissors unit motion boundary line.
The pole scissors unit 1 that four folding and expanding direction of motion is identical is connected to form a collapsible expansion by hoop
Rectangular pyramid unit 3, as shown in Figure 2.Any one pole scissors unit 1 of anchor portion, is the formation of single-degree-of-freedom system, can
Realize entirety launch and fold.For avoiding geometry incompatible pole size all next really by doing boost line after determining structural span
Fixed.One rectangular pyramid unit 3 is regarded as with a pole scissors unit 1 as object, and this pole scissors unit 1 folding and expanding is transported
Put what annular array was formed centered by the disorder of internal organs heart.N such rectangular pyramid unit 3 joins end to end, and is directed around half along span
Circumference forms a Pin and folds arch unit 4.Forward pole scissors unit 11 is connected signal such as with a reverse pole scissors unit 12
Shown in Fig. 3, along structure length direction, adjacent pole scissors unit motion is in opposite direction.Every Pin folds between arch unit by (n+1)
The individual pole scissors unit in opposite direction with folding the interior basic pole scissors unit motion of arch is connected, and is the formation of collapsible cylinder
Net shell 5.
Rigid roofing 6 is split into plane as shown in Figure 4.Each rigid roofing Slab element 7 is made up of four quadrangular plate, described
Four parallelogram 7 plate conllinear two-by-two also intersect at a summit, according to being respectively the first quadrangular plate the 71, the 2nd 4 counterclockwise
Limit shape plate the 72, the 3rd quadrangular plate 73 and the 4th quadrangular plate 74, the common edge between them be respectively the first common edge 75,
Two common edge the 76, the 3rd common edge 77 and the 4th common edge 78；In motor process, first quadrangular plate the 71, second tetragon
Plate 72 and the 3rd quadrangular plate the 73, the 4th quadrangular plate 74 are the planes formed about the second common edge 76 and the 4th common edge 78
Symmetrical.The second described common edge the 76, the 3rd common edge 77 and the 4th common edge 78 are crest line, and the first common edge 75 is paddy
Line, adjacent quadrangular plate 7 is folded-out along crest line, along valley line fold inward, described folded-out refer to adjacent flat
Angle between the exterior normal of row quadrangular plate 7 becomes big, and fold inward refers between the exterior normal of adjacent parallelogram plate 7
Angle diminish.Described first quadrangular plate 71 is distinguished with the angle of the first common edge 75 in the sideline of the first common edge 75 both sides
It is the first angle 79 and the second angle 710；Described 3rd quadrangular plate 73 is public with first in the sideline of the 3rd common edge 77 both sides
The angle on limit 75 is respectively the 3rd angle 711 and the 4th angle 712 altogether；First angle 79 and the 4th angle 712 supplementary angle each other, the
Two angle 710 and the 3rd angle 711 supplementary angles each other；And second angle 710 and the 4th angle 712 unequal.
After folding up, rotate according to certain angle between span direction different lines rigid roofing Slab element 7
Arrangement, thus define the arc surface with certain curvature.And on cylindrical reticulated shell 5 length direction, rigid roofing Slab element 7 is each
Row is parallel.So system will form the configuration of cylinder shell in motor process.Can with bottom by the rigid roofing 6 folded up
Folding cylindrical reticulated shell 5 to be connected, on the most each rectangular pyramid unit 2, a corresponding rigid roofing Slab element is (with rigid roofing Slab element
4 nodes of outmost turns are hinged, as shown in Figure 6), by 4 nodes (31,32,33 and 34) of every sub-pyramid unit 3 upper end,
See Fig. 2, hinged, such as Fig. 5 with 4 nodes (713,714,715 and 716) of rigid roofing Slab element outmost turns respectively.
Overall structure structure is as shown in Figure 7.During folding into expansion, the geometric shape of model has bigger difference.
