Detailed ways

The present invention will be further described below in conjunction with embodiment, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art can modify various equivalent forms of the present invention All fall within the scope defined by the appended claims of this application.

As shown in Figure 1 and Figure 2, the planar open-close roof structure that can realize two-way linkage and folding involved in this embodiment includes several foldable quadrangular pyramid units 1, and different quadrangular pyramid units 1 are connected to each other and form a matrix The expansion and contraction of the overall roof structure is realized through the expansion and contraction of each quadrangular pyramid unit 1.

Specifically, as shown in FIG. 3 , the quadrangular pyramid unit 1 includes five node members 2 , four first telescopic rods 3 and four rigid rods 4 with the same length. The five node components 2 are respectively located at the four bottom corners and one top corner of the quadrangular pyramid unit 1 , and the four first telescopic rods 3 are fixedly connected with the node components 2 at the four bottom corners to form a rectangular bottom surface 5 . The two ends of the rigid rod 4 are respectively hinged with the node member 2 at the top corner and at the bottom corner. Four rigid rods 4 constitute the four edges of the quadrangular pyramid unit 1. Since the four rigid rods 4 have the same length, the projection of the node member 2 at the apex of the quadrangular pyramid unit 1 on the rectangular bottom 5 is the center of the rectangular bottom 5. The quadrangular pyramid units 1 are fixedly connected, and adjacent quadrangular pyramid units 1 share a first telescopic rod 3 and two node components 2 . The bottom surfaces of all the quadrangular pyramid units 1 are arranged in a matrix and are on the same plane, and the node members 2 at the top corners of the quadrangular pyramid units 1 are fixedly connected with second telescopic rods 6 . The first telescopic rod 3 and the second telescopic rod 6 are multi-section cable-type telescopic rods, and the limit lengths of the first telescopic rod 3 and the second telescopic rod 6 are equal.

Taking any two adjacent quadrangular pyramid units as an example, Figure 4 shows four rigid rods a, b, c, d on the opposite surfaces of two adjacent quadrangular pyramid units, A and C are phase Two shared node members of adjacent quadrangular pyramid units, B and D are two node members located at the top corners of adjacent quadrangular pyramid units, Z _A is the rotation axis of rigid rods a and b around node member A, Z _C is the rotation axis of rigid rods c and d around node member C, Z _B is the hinge axis of the second rotation pair of rigid rods b, c and node member B, and Z _D is the second rotation of rigid rods d, a and node member D The hinge axis of the pair, θ _A is the angle between rigid rod a and b, θ _B is the angle between rigid rod b and c, θ _C is the angle between rigid rod c and d, θ _D is the angle between rigid rod d and a, θ _AB is the angle between Z _A and Z _B , α _BC is the angle between Z _B and Z _C , α _CD is the angle between Z _C and Z _D , and α _DA is the angle between Z _D and Z _A. The structure satisfies α _AB = α _CD = α, α _BC = α _DA = β, θ _A = θ, θ _A + θ _C = 2π, θ _B + θ _D = 2π, and α=π-arccos(1/3).

Please refer to Fig. 5 and Fig. 6 again, the node member 2 includes a connecting head 7 and two angled connecting pieces 8, the first telescopic rod 3 and the second telescopic rod 6 and the connecting head 7 are welded, riveted or bolts and nuts etc. The two angled connecting pieces 8 are symmetrically arranged and hinged with the connecting head 7 to form the first rotating pair. The head end of the rigid rod 4 is provided with a knuckle joint 9, and the knuckle joint 9 is hinged with the knuckle joint 8 to form a second rotating pair. The rotation plane of the first rotation pair is orthogonal to the rotation plane of the second rotation pair, the distance between the rotation axis A of the first rotation pair and the rotation plane of the second rotation pair is greater than zero, and the rotation axis B of the second rotation pair is the axis of the rigid rod 4 C disjoint. Such setting enables two adjacent rigid rods 4 to achieve the effect of being parallel to each other when shrinking, and to achieve maximum shrinkage. The rotating shafts A of the first rotating pair of five node components 2 on the single quadrangular pyramid unit 1 are arranged parallel to each other, because the adjacent quadrangular pyramid unit 1 shares a first expansion link 3 and two node components 2, so the whole can The rotation axes A of the first revolving pairs of the node members 2 of all quadrangular pyramid units 1 on the planar open-close roof structure that realizes two-way linkage folding are arranged in parallel to each other.

It should be pointed out that the above-mentioned embodiment is a preferred solution of the present invention, a certain interval can be set between adjacent quadrangular pyramid units 1, and the distance between quadrangular pyramid units 1 can be compensated by increasing the second telescopic rod length 6 accordingly That's it.
