Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in Figure 1, the basic unit of foldable cylindrical reticulated shell is pole scissors unit 1.Each pole scissors unit 1 by
Two poles 2 form, and at 2 midpoint of pole, dotted line is pole scissors unit motion boundary line for bending place.
The identical pole scissors unit 1 of four folding and expanding directions of motion is connected to form a foldable expansion by circumferential direction
Rectangular pyramid unit 3, as shown in Figure 2.Fixed any one pole scissors unit 1 of end, is formed single-degree-of-freedom system, can
Realize whole unfold and fold.Determine after structural span for avoid the incompatible pole size of geometry all by do auxiliary line come it is true
It is fixed.One rectangular pyramid unit 3 is regarded as with a pole scissors unit 1 as object, 1 folding and expanding of pole scissors unit fortune
Point annular array is formed centered on dynamic center.N such rectangular pyramid units 3 join end to end, and are directed around half along span
Circumference forms a Pin and folds arch unit 4.Positive pole scissors unit and a reversed pole scissors unit are connected signal such as Fig. 3 institute
Show, along structure length direction, adjacent pole scissors unit motion is contrary.Every Pin fold between arch unit by (n+1) it is a with
It folds the pole scissors unit that basic pole scissors unit motion is contrary in arch to be connected, is formed foldable cylindrical reticulated shell

Symmetrically.Second common edge 76, third common edge 77 and the 4th common edge 78 is crest line, and the first common edge 75 is paddy
Line, adjacent quadrangular plate are foldable outwardly along crest line, are folded inward along valley line, and the outward folding refers to adjacent parallel
Angle between the exterior normal of quadrangular plate becomes larger, and the folder between the exterior normal for referring to adjacent parallelogram plate is folded inward
Angle becomes smaller.First quadrangular plate 71 is respectively the in the sideline of 75 two sides of the first common edge and the angle of the first common edge 75
One angle 79 and the second angle 710；Sideline and third common edge of the third quadrangular plate 73 in 77 two sides of third common edge
77 angle is respectively third angle 711 and the 4th angle 712；First angle 79 and the 4th angle 712 supplementary angle each other, the second folder
Angle 710 and third angle 711 supplementary angle each other；And second angle 710 and the 4th angle 712 it is unequal.
After folding up, rotated between span direction different lines rigid roofing plate unit 7 according to certain angle
Arrangement, so as to form the arc surface with certain curvature.And on foldable 5 length direction of cylindrical reticulated shell, rigid roofing plate list
First 7 every a line are parallel.So system will form the configuration of cylinder shell during the motion.The rigid roofing 6 that will be folded up
It is connected with the foldable cylindrical reticulated shell 5 in lower part, i.e., a corresponding rigid roofing plate unit is (with rigid room on each rectangular pyramid unit 3
4 nodes of panel unit outmost turns are hinged, as shown in Figure 6), by 4 nodes of each 3 upper end of rectangular pyramid unit (31,32,
33 and 34), referring to fig. 2, respectively hingedly with 4 nodes (713,714,715 and 716) of rigid roofing plate unit outmost turns, such as
Fig. 5.
Overall structure structure is as shown in Figure 7.The geometric shape of model has bigger difference during folding into expansion.
