Example Embodiment
[0039] Example 1
[0040] refer to figure 2 and image 3 , The rectangular truss type reflective curved surface unfolding device of the present invention includes: a ring connecting joint 1 and a folding ring 2, both of which are complex numbers, and the specific number is determined according to the size of the unfolded curved surface. in:
[0041] The structure of the ring connection joint 1 is as follows Figure 10 (a) and Figure 10 As shown in (b), it is composed of a pair of bevel gear structures 101, 102 and a pair of splints 103, 104, a pair of splints are respectively fixed inside and outside the pair of bevel gear structures, and between the pair of bevel gear structures and the pair of splints An angle of 160 to 180 degrees is set at the splint, so that the ring structure can rotate in a plane around a fixed axis during the process of retracting to unfolding. The size of the angle is related to the number of ring rods, that is, determined according to the form...

[0047] Example 3
[0048] refer to Figure 5 and Image 6 , The regular triangle truss type reflective curved surface unfolding device of the present invention includes: a ring connecting joint 1 and a folding ring 2, both of which are plural, and the specific number is determined according to the size of the unfolded curved surface. in:
[0049] The structure of the ring connection joint 1 is as follows Figure 10 (a) and Figure 10 As shown in (b), it is composed of a pair of bevel gear structures 101, 102 and a pair of splints 103, 104, a pair of splints are respectively fixed inside and outside the pair of bevel gear structures, and between the pair of bevel gear structures and the pair of splints An angle of 160 to 180 degrees is set at the splint, so that the ring structure can rotate in a plane around a fixed axis during the process of retracting to unfolding. The size of the angle is related to the number of ring rods, that is, determined according to the formula:...
