[0040] In order to realize the folding and stowing of the space inflatable deployment structure and meet the state conversion requirements of the space inflatable deployment structure during the ground test phase. The present invention provides a folding and stowing method for a space inflatable deployment structure, combined with Figures 1 to 12 As shown, the specific folding and collapsing method for the space inflatable expansion structure includes: electrically heating the space inflatable expansion structure 6 so that the space inflatable expansion structure 6 is in a softened state; further, electrically connecting a power source to the space inflatable expansion structure 6, and electrically heating the space inflatable expansion structure 6 by supplying power to the power source.
[0041] Combination Figure 2 , Figure 3 and Figure 8 As shown, the space inflatable expansion structure 6 in a softened state is flattened and exhausted so that the space inflatable expansion structure 6 is in a flat state; specifically, the flattening and exhausting process is to use a pressure roller 1 to manually flatten and roll the surface of the product or to use a roller device 3 to automatically flatten and roll both sides of the product.
[0042] In an alternative embodiment, referring to Figure 3 , Figure 4 and Figure 5 As shown, a pressure roller 1 is used to flatten the surface of the space inflatable expansion structure 6 in a softened state and roll along the extension direction of the space inflatable expansion structure 6. Furthermore, a buffer layer 11 is provided on the surface of the pressure roller 1 that contacts the space inflatable expansion structure 6.
[0043] In another alternative embodiment, referring to Figure 8 , Fig.10 and Fig.11 As shown, the space inflatable expansion structure 6 in a softened state is flattened and rolled on both sides by the roller device 3. The space inflatable expansion structure 6 can move relative to the roller device 3 along the extension direction of the space inflatable expansion structure 6. The roller device 3 includes two cylindrical rollers 31 arranged opposite to each other; the space inflatable expansion structure 6 is located between the two cylindrical rollers 31; the two cylindrical rollers 31 are configured to be able to approach or move away from each other, so that the space inflatable expansion structure 6 can be pressed between the two cylindrical rollers 31, refer to Fig.11 As shown, the arrow in the figure points to the direction of movement of the two cylindrical rollers 31 in a horizontal plane when they move away from each other in a direction perpendicular to the extension direction of the space inflatable expansion structure 6. When the space inflatable expansion structure 6 is crimped between the two cylindrical rollers 31, the space inflatable expansion structure 6 starts to move, driving the two cylindrical rollers 31 to roll and flatten the space inflatable expansion structure 6.
[0044] Combination Figure 6-Figure 11 As shown, the space inflatable expansion structure 6 in a flat state is flipped and folded so that the space inflatable expansion structure 6 is in a folded and gathered state; the flipping and folding process is to manually position the flattened product according to a certain size through the flipping plate 2 and then manually flip and fold it, or to automatically flip and fold the flattened product according to a certain size requirement through the folding mechanism 4.
[0045] In an alternative embodiment, referring to Figure 6 , Figure 7 As shown, the space inflatable expansion structure 6 is positioned by a flip plate 2 and then flipped and folded. The flip plate 2 is provided with positioning pins 21, and positioning holes are provided on both side edges of the space inflatable expansion structure 6. The flip plate 2 can position the space inflatable expansion structure 6 through the positioning pins 21.
[0046] In another alternative embodiment, referring to Figure 8-Figure 11As shown, the space inflatable expansion structure 6 is flipped and folded by a folding mechanism 4. Specifically, the folding mechanism 4 includes two oppositely arranged guide plates 5, a two-dimensional mobile platform 42 and a lever 41 configured on the two-dimensional mobile platform 42; the space inflatable expansion structure 6 is located between the two guide plates 5 and can move along the extension direction of the space inflatable expansion structure 6; the lever 41 is configured to flip, fold and press the part of the space inflatable expansion structure 6 that moves from between the two guide plates 5 to outside the two guide plates 5 under the drive of the two-dimensional mobile platform 42. It can be understood that the two guide plates 5 are fixed relative to the space inflatable expansion structure 6, and the two guide plates 5 can be fixed to other components through a support member (not shown in the figure). Through the above arrangement, the two-dimensional mobile platform 42 is used to drive the lever 41 to move, so that the part of the space inflatable expansion structure 6 located on the right side of the guide plate 5 is folded counterclockwise and pressed against the outer surface of the guide plate 5, and the space inflatable expansion structure 6 moves to the right for a certain distance, and the lever 41 is reset. The two-dimensional mobile platform 42 is used to drive the lever 41 to move, so that the part of the space inflatable expansion structure 6 located on the right side of the guide plate 5 is folded clockwise and pressed against the outer surface of the guide plate 5, and this cycle is repeated until the entire space inflatable expansion structure 6 is flipped and folded, and the space inflatable expansion structure 6 is in a folded and retracted state.
[0047] The space inflatable deployment structure 6 in the folded and collapsed state is powered off, and further, the space inflatable deployment structure 6 is powered off by power cut-off.
[0048] In actual use, the initial state of the space inflatable expansion structure 6 is the expansion and solidification state. Figure 1 As shown; at this time, the power is turned on to heat the space inflatable expansion structure 6. After a period of time, the space inflatable expansion structure 6 begins to soften; at this time, the pressure roller 1 or the roller device 3 is used to flatten and exhaust the space inflatable expansion structure 6, so that the space inflatable expansion structure 6 is flattened, as shown. Figure 3 , Figure 8 After the space inflatable expansion structure 6 is flattened and exhausted, the product is flipped and folded using the flip plate 2 or the folding mechanism 4 so that the product is in a folded and collapsed state, such as Fig.11 Turn off the power to cut off the power, take out the space inflatable expansion structure 6 in the folded state, as shown Fig.12 shown.
[0049] To sum up, the folding and gathering method provided by the present invention realizes the folding and gathering function of the space inflatable deployment structure through power-on heating, flattening and exhausting, flipping and folding, and power-off processes in conjunction with corresponding operating devices (such as the pressure roller, flipping plate, roller device and folding mechanism in the above-mentioned embodiment). It has the characteristics of reasonable method and strong feasibility, so that the space inflatable deployment structure can be converted multiple times between the softened folded state and the unfolded and solidified state, meeting the state conversion requirements of the space inflatable deployment structure during the ground testing stage, saving operation time and improving work efficiency.
[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
