specific Embodiment approach 1

[0018] Specific implementation mode one: see Figure 1 to Figure 10 , the deployment control device of a three-dimensional inflatable unfolded truss structure described in this embodiment includes a folding loading box 1 and an eight-column spring sheet array 2, the folding loading box 1 is a rectangular parallelepiped thin-walled box structure, and the folding loading box 1 The front side wall is a box cover 9, the front end of the folding loading box 1 is the expanded extension end of the inflatable unfolding truss 4, the rear side wall 3 of the folding loading box 1 is the fixed end of the inflatable unfolding truss 4, and the rear side of the folding loading box 1 The wall 3 is provided with a plurality of fixing screw holes 5 and a plurality of through holes 6, the plurality of fixing screw holes 5 are used to fix the inflatable unfolding truss 4, and the inflation conduit used when the inflatable expanding truss 4 is inflated and expanded passes through the through holes ...

specific Embodiment approach 2

[0019] Specific implementation mode two: see Figure 3 to Figure 10 , as the deployment control device of a three-dimensional inflatable unfolded truss structure described in Embodiment 1, each folded section of each main support tube 10 arranged along the length direction on the inflated unfolded truss 4 is constrained to be located in the same row of spring leaf arrays 2 between two adjacent rectangular spring pieces 8.

[0020] The main support tubes 10 arranged along the length direction in the inflatable deployment truss 4 in this embodiment are folded in a Z shape when folded. All the main support tubes 10 arranged along the length direction of the inflatable deployment truss 4 are folded into a Z-shaped folded state.

specific Embodiment approach 3

[0021] Specific implementation mode three: see Figure 1 ~ Figure 4 and Figure 7 ~ Figure 10 Illustrate, as the deployment control device of a three-dimensional inflatable deployment truss structure described in Embodiment 1 or 2, the number of multiple through holes 6 is four, and the four through holes 6 are located on the rear side wall 3 of the folding loading box 1 The top is arranged in a rectangular shape, and the number of multiple fixing screw holes 5 is sixteen. The sixteen fixing screw holes 5 are divided into four groups, and the four groups of fixing screw holes are set in one-to-one correspondence with the four through holes 6. Each group of fixing screw holes The number is four, and the four fixing screw holes 5 in each set of fixing screw holes are uniformly arranged on the outer periphery of the corresponding through holes 6 . The purpose of this design is to fix an inflatable expansion main support pipe 10 of the inflatable expansion truss 4, so that sixtee...

Abstract

The invention provides an unfolding control device for a three-dimensional inflatable unfolding truss structure, which relates to the unfolding control device for a three-dimensional truss structure and solves the problem that no unfolding control device for the three-dimensional truss structure exists so far. A back sidewall of a folding loading box is a fixed end of an inflatable unfolding truss; four columns of leaf spring arrays are mounted on the inside surface of a left sidewall of the folding loading box and the inside surface of a right sidewall of the folding loading box respectively; each column of the leaf spring arrays consists of a plurality of rectangular leaf springs; both the rectangular leaf springs of the four columns of the leaf spring arrays mounted on the inside surface of the left sidewall of the folding loading box and the rectangular leaf springs of the four columns of the leaf spring arrays mounted on the inside surface of the right sidewall are respectively distributed along an unfolding direction of the folding loading box; intervals are retained between the rectangular leaf springs in each column of the leaf spring arrays which are adjacent to a box cover of the folding loading box and the box cover of the folding loading box; and an upper-section box cover and a lower-section box cover are hinged with the upper end face and the lower end face of the folding loading box. The unfolding control device is used for controlling the three-dimensional inflatable unfolding truss structure to orderly unfold.

Description

technical field [0001] The invention relates to a deployment control device for a three-dimensional truss structure. Background technique [0002] The three-dimensional inflatable unfolding truss structure is a new type of truss structure for spacecraft that is constructed of flexible composite materials, can be launched in a foldable package, and can be inflated and expanded and rigidized after entering orbit. It has high folding efficiency, small launch volume, light weight, and simple structure. And other advantages, can be widely used in satellites, space stations and other spacecraft. The structure of the three-dimensional inflatable unfolding truss is relatively simple, without mechanical joints such as mechanical hinges and locking mechanisms; it only needs inflation pressure to drive the deployment, no motor drive, no transmission mechanism, and the drive method is simple. The inflatable deployment truss structure is flexible before deployment. If the deployment pro...
