[0029] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following is for reference. Figures 1-7 This invention describes a layer-blocking rigidizable inflatable structure 100 for rapid construction in extreme environments according to an embodiment of the present invention. The layer-blocking rigidizable inflatable structure 100 of this application is a temporary building or temporary structure that can be rapidly constructed and can be applied to various extreme environments and to cope with some temporary construction tasks.

[0031] This application proposes a layered, rigidizable inflatable structure 100 for rapid construction in extreme environments. The layered, rigidizable inflatable structure 100 includes a flexible skin structure 10 and a layered blocking member 20. The flexible skin structure 10 is adapted to inflate and unfold or deflate and fold, facilitating switching between a use mode and a storage mode. When inflated and unfolded, the flexible skin structure 10 forms the main body of the inflatable structure and is adapted to seal the internal gas and withstand the internal air pressure. The layered blocking member 20 is disposed on the surface of the flexible skin structure 10. The layered blocking member 20 is adapted to undergo stiffness changes, and in its rigidified state, it is adapted to provide reinforcement and support to the main body of the inflatable structure to maintain the inflatable structure. The main body's shape is suitable for preventing the inflatable structure from collapsing when the flexible skin structure 10 leaks air; the layer blocking component 20 includes a vacuum bag 21 and a flexible material component 22. The vacuum bag 21 is disposed on the surface of the flexible skin structure 10 and is suitable for evacuating or releasing a vacuum; the flexible material component 22 is disposed inside the vacuum bag 21, and the flexible material component 22 is constructed in multiple layers; when evacuating a vacuum inside the vacuum bag 21, the interlayer friction between the multiple layers of flexible material components 22 increases to increase the stiffness of the layer blocking component 20; when releasing a vacuum inside the vacuum bag 21, the interlayer friction between the multiple layers of flexible material components 22 decreases to decrease the stiffness of the layer blocking component 20.

[0032] The layer blocking rigidizable inflatable structure 100 according to the present application, the flexible skin structure 10 can be switched between the use mode and the storage mode through inflation and deflation, the use mode refers to the unfolded mode of the flexible skin structure 10 after inflation, that is, the mode of the flexible skin structure 10 in service, and the flexible skin structure 10 forms an inflated structure body after inflation; the storage mode refers to the mode of the flexible skin structure 10 after deflation. The layer blocking member 20 can change the rigidity by vacuumizing and releasing the vacuum of the vacuum bag 21, and in the low rigidity state, the layer blocking member 20 of the present application can be folded after releasing the vacuum, because the vacuum bag 21 and the flexible material member 22 both have flexible characteristics. Therefore, the overall layer blocking rigidizable inflatable structure 100 of the present application can be folded and unfolded, and can meet different requirements of the structure during transportation, construction and service. The layer blocking rigidizable inflatable structure 100 of the present application in the folded state has small volume and light weight, which can meet the requirements of volume and mass during transportation, and is convenient for storage and transportation.

[0033] The flexible skin structure 10 according to the present application can maintain internal sealing to prevent internal gas leakage in the use mode, and can withstand internal gas pressure.

[0034] The layer blocking member 20 according to the present application, as shown in Figure 2 The layer blocking member 20 includes a vacuum bag 21 and a flexible material member 22, and the air pressure of the vacuum bag 21 can be changed by vacuumizing and releasing the vacuum. After vacuumizing, an air pressure difference is formed between the inside and outside of the vacuum bag 21, and the confining pressure generated by the air pressure difference acts on the flexible material member 22, so that the interlayer friction of the multiple layers of the flexible material member 22 increases, the interlayer shear capacity improves, and the bending stiffness of the layer blocking member 20 increases. During the service of the layer blocking rigidizable inflatable structure 100, the layer blocking member 20 after vacuumizing has a certain bending stiffness, which can on the one hand reinforce the inflated structure body, improve the bending resistance, and improve the carrying capacity of the structure; on the other hand, the layer blocking member 20 can support the inflated structure body, so that the structure can withstand a certain pressure when the flexible skin structure 10 leaks, and the shape is not collapsed, which can provide time for personnel safety evacuation, and is convenient for subsequent repair. After repair, the flexible skin structure 10 can be inflated and pressurized again for continued service, thereby greatly improving the safety and repairability of the structure.

[0035] The layer blocking member 20 and the flexible skin structure 10 of the present embodiment are both controlled by air pressure, which can be realized by an automatic system in practice, and the construction process can be automatically completed, which is convenient for improving the automation degree of the construction process, simplifying the operation process, realizing rapid construction, and especially having significant advantages in extreme environments such as lunar environment through automatic control for construction.

[0036] In addition, since the layer blocking piece 20 and the flexible skin structure 10 are both controlled by air pressure, the control process is reversible, the control method is simple, and the control speed is fast, which on the one hand helps to carry out various repeatable ground tests and multiple uses, such as inflation deployment test, rigidification test, compression resistance test, air tightness test, construction process demonstration, etc., which is conducive to the study of the performance of the layer blocking rigidifiable inflatable structure 100; on the other hand, the layer blocking rigidifiable inflatable structure 100 of the present application can be recycled, which can improve the utilization rate of resources and play an important role in extreme environments such as the lunar surface environment.

[0037] As shown in Figure 3 The recycling process of the layer blocking rigidifiable inflatable structure 100 according to the present application is as follows: first, inflate and deploy the flexible skin structure 10 to form an inflatable structure body, specifically, if on the ground, keep the air pressure inside the flexible skin structure 10 at 150 pa-250 pa, before vacuum extraction, the direct interlayer constraint of the multilayer flexible material piece 22 is small, and the vacuum bag 21 is relatively soft, which can adapt to the shape of the surface of the flexible skin structure 10 after inflation and deployment; second, rigidify the layer blocking piece 20, specifically, after vacuum extraction, due to the pressure difference, the interlayer static friction increases, which increases the bending stiffness of the layer blocking piece 20, thereby producing a rigidification effect. The rigidified structure can prevent the inflatable structure body from collapsing and maintain the structure shape even if the flexible skin structure 10 leaks and the internal pressure is 0 pa, greatly improving the safety of the structure; after the above steps, the layer blocking rigidifiable inflatable structure 100 is built and can start to serve, at this time the flexible skin structure 10 is in a use state; finally, after the service is completed, the structure is disassembled, specifically, when disassembling, first remove the external load, in the case of no load bearing requirement, the vacuum of the layer blocking piece 20 can be released first, and then the air pressure inside the flexible skin structure 10 is released, the structure is folded and stored, or the air pressure inside the flexible skin structure 10 is released first, and then the vacuum in the layer blocking piece 20 is released, the structure is folded and stored, at this time the flexible skin structure 10 is in a storage state, and the layer blocking rigidifiable inflatable structure 100 is folded and stored for reuse.

[0038] Further, during the service stage of the layer blocking rigidifiable inflatable structure 100, friction may occur between the multilayer flexible material piece 22 due to external forces, which can consume energy and resist impact load, environmental vibration or other dynamic excitation. The present application can further improve the stability and reliability of the layer blocking rigidifiable inflatable structure 100.

[0039] In addition, after the flexible skin structure 10 is unfolded, a spacious space is formed inside the inflatable structure body, which can be sealed, has good airtightness and safety, can maintain the atmospheric pressure required for human activities, can be used as a personnel operation space, and can be applied to extreme environments such as the lunar surface environment that lack air.

[0040] Further, the gas in the layer blocking member 20 and the flexible skin structure 10 can be recycled, for example, the gas extracted from the layer blocking member 20 can be filled into the flexible skin structure 10 for pressurization, and can be recycled, which can save gas resources and improve resource utilization in extreme environments such as the lunar surface environment that lack air.

[0041] The layer blocking rigidizable inflatable structure 100 according to the present application has the following advantages: first, the layer blocking rigidizable inflatable structure 100 is lightweight and foldable, convenient to transport, and can be used in environments that need to be quickly built and extreme environments; second, the present application uses pressure control, which is simple to control, the process is reversible, the control speed is fast, and is helpful for repeated ground tests and multiple uses; third, the air extracted during the vacuum rigidization process of the layer blocking member 20 can be collected for internal pressurization of the flexible skin structure 10, and the recycling of this part of the air is crucial for environments such as the lunar surface that lack air; fourth, the construction process of the layer blocking rigidizable inflatable structure 100 is simple, including the main steps of inflation and unfolding, vacuum rigidization, and pressurization, and does not require additional structural materials, and has high controllable automation; fifth, during the service stage of the structure, the layer blocking member 20 can dissipate energy through interlayer friction, which can be used to resist impact dynamic loads, moonquakes, and other dynamic excitations, and maintain the stability and safety of the structure.

[0042] In some embodiments, the layer blocking rigidizable inflatable structure 100 can adopt a spherical, hemispherical, cylindrical, or other shape.

[0043] According to some embodiments of the present application, the flexible material member 22 is configured as a fiber fabric. The fiber fabric in this embodiment refers to a flexible product composed of fiber materials and yarns interwoven. Because the fiber materials and yarns are arranged in multiple directions and interwoven with each other, the fiber materials and yarns themselves have friction properties, and the surface of the fiber fabric has a high friction coefficient. In this embodiment, the flexible material member 22 is configured as a fiber fabric, so that a larger friction force is easily generated between the flexible material members 22, which can effectively improve the rigidity of the layer blocking member 20. At the same time, the fiber fabric has high flexibility and light weight, which can improve the deformation effect of the layer blocking member 20 and reduce the load on the inflatable structure body.

[0044] According to some embodiments of this application, the layer blocking member 20 is constructed as a single unit and covers the surface of the flexible skin structure 10; or the layer blocking member 20 is constructed as a plurality of units, which are spaced apart on the surface of the flexible skin structure 10, and the layer blocking member 20 is constructed as a strip. The number and arrangement of the layer blocking members 20 in this embodiment depend on the size of the layer blocking rigidifiable inflatable structure 100.

[0045] In some embodiments, such as Figure 4 As shown, when the layer blocking member 20 is constructed as a single unit and covers the surface of the flexible skin structure 10, the layer blocking member 20 can achieve vacuuming or vacuum release in one step, which can improve the folding and unfolding efficiency of the layer-blocked rigid inflatable structure 100, simplify the construction process, and achieve rapid construction. In some embodiments, such as Figure 1 As shown, multiple layer-blocking members 20 are constructed, with multiple strip-shaped layer-blocking members 20 spaced apart on the surface of the flexible skin structure 10, equivalent to stiffening ribs of the inflatable structure body. Each layer-blocking member 20 is partially attached to the flexible skin structure 10. In this embodiment, the multiple layer-blocking members 20 can disperse the constraint force applied to the flexible skin structure 10. The multiple layer-blocking members 20 are independent of each other, which can play an additional constraint role, preventing any layer-blocking member 20 from losing stiffness and affecting the stability of the structure, thereby improving the reinforcement and support effect of the inflatable structure body.

[0046] According to some embodiments of this application, such as Figure 5 As shown, when the layered rigid inflatable structure 100 is in service in the lunar environment, its outer surface may optionally be provided with a lunar regolith cover layer 30. The lunar regolith cover layer 30 covers the outer surface of the layered rigid inflatable structure 100 when the flexible skin structure 10 is in use. In this embodiment, the lunar regolith cover layer 30 is mainly used in the lunar environment and is constructed from in-situ lunar resources, such as compacted lunar regolith, lunar regolith bags, or lunar regolith bricks. The lunar regolith cover layer 30 covers the outer surface of the layered rigid inflatable structure 100 when the flexible skin structure 10 is in use, such as… Figure 5 As shown, the completed lunar soil cover layer 30 with layer-blocking rigid inflatable structure 100 can serve as a protective layer, providing functions such as heat insulation, protection against cosmic radiation, and protection against meteorite impacts.

[0047] For the rigid, inflatable, layered cover structure 100 required in the lunar environment, in addition to considering its performance during the static service phase, the safety of the structure during dynamic construction is also a key concern. During construction, before the lunar regolith is completed, a self-supporting structure is not yet formed. The rigidified, inflatable, layered cover structure 100 serves to support the unformed external lunar regolith components and construction templates, thus bearing the load and acting as a formwork. The rigidified, inflatable, layered cover structure 100 can also withstand the pressure exerted by the lunar regolith protective layer during construction. Furthermore, after the lunar regolith cover layer 30 is constructed, it can also form an independent pressure-bearing structure, capable of self-support and independent load-bearing, avoiding damage to the internal rigid, inflatable, layered cover structure 100. In addition, the lunar regolith cover layer 30 is constructed on the moon using in-situ lunar resources, such as compacted lunar regolith, lunar regolith bags, or lunar regolith bricks, improving the utilization rate of in-situ lunar resources. Furthermore, the construction of the lunar regolith cover layer 30 is largely a repetitive task, primarily performed by construction robots.

[0048] According to some embodiments of this application, the layer blocking member 20 is disposed on the inner surface or the outer surface of the flexible skin structure 10. In this embodiment, whether the layer blocking member 20 is disposed on the inner or outer surface of the flexible skin structure 10, it can achieve the technical effect of providing reinforcement and support after rigidification. In practice, due to the vacuum environment on the lunar surface, the pressure control of the layer blocking member will have a significant impact. Therefore, when disposing of the layer blocking member 20 on the inner or outer surface of the flexible skin structure 10, adaptability to the lunar environment must be a key consideration.

[0049] In some embodiments, such as Figure 6 As shown, the layered blocking element 20 is disposed on the inner surface of the flexible skin structure 10. The flexible skin structure 10 and the layered blocking element 20 are subjected to internal air pressure F1. A tensile force F2 is generated within the flexible skin structure 10. Because the layered blocking element 20 compresses the flexible skin structure 10 under the action of F1, the flexible skin structure 10 generates a reaction force on the layered blocking element 20. This results in the layered blocking element 20 being subjected to the compressive forces of the flexible skin structure 10 and the internal gas, achieving force balance. In this case, since the layered blocking rigid inflatable structure 100 has reached equilibrium, the pressure F3 of the external soil layer on the layered blocking rigid inflatable structure 100 will offset part of the internal pressure, but its contribution to the compressive force on the layered blocking element 20 is limited. Therefore, when the layered blocking element 20 is disposed inside the flexible skin structure 10, an external soil layer is not required.

[0050] In some embodiments, such as Figure 7As shown, the layer blocking member 20 is arranged on the outer surface of the flexible skin structure 10. In this embodiment, the flexible skin structure 10 is subjected to the internal air pressure F1, and a tensile force F2 is generated in the structure to achieve force balance. Meanwhile, the layer blocking member 20 is subjected to the external air pressure in the ground environment; the layer blocking member 20 is rigidized by being extruded by the flexible skin structure 10 and the ambient air pressure when being internally vacuumized. If the layer blocking rigidizable inflatable structure 100 is arranged in an extreme environment such as the lunar environment, the external layer blocking member 20 will not be extruded due to insufficient ambient air pressure, and can be freely deformed outward. In this case, if extrusion is desired, a lunar soil covering layer 30 needs to be added to the outer surface of the layer blocking member 20, and the extrusion force on the layer blocking member 20 depends on the earth pressure F3 of the external lunar soil covering layer 30, as shown. Figure 5

[0051] According to some embodiments of the present application, the flexible skin structure 10 comprises a sealed air bag layer 11 and a reinforcing layer 12. The sealed air bag layer 11 is adapted to seal the gas inside the flexible skin structure 10; and the reinforcing layer 12 is arranged on the outer surface of the sealed air bag layer 11 and is adapted to bear the air pressure inside the flexible skin structure 10. In this embodiment, the sealed air bag layer 11 has air tightness to prevent gas leakage; and the reinforcing layer 12 is arranged on the outer surface of the sealed air bag layer 11 and serves as the main structure layer to bear the internal air pressure of the sealed air bag layer 11, thereby improving the load bearing capacity of the inflatable structure body.

[0052] According to some embodiments of the present application, the sealed air bag layer 11 is made of single-layer or multi-layer film material. Specifically, the thickness of the sealed air bag layer 11 is several millimeters, and the film material can be selected from polyurethane, polyethylene, polyamide, etc., so that the sealed air bag layer 11 has the characteristics of flexibility, light weight, and good air tightness, and can be used to prevent gas leakage in the layer blocking rigidizable inflatable structure 100; at the same time, it is convenient to unfold or fold and compress, and is convenient for storage and transportation.

[0053] In some embodiments, the inner surface of the sealed air bag layer 11 is further provided with a scratch-resistant layer, which can be made of aramid felt or the like, for protecting the sealed air bag layer 11 from mechanical damage during use.

[0054] ​According to some embodiments of the present application, the reinforcing layer 12 is configured as a high-strength fiber fabric and is isotropic. In this embodiment, the reinforcing layer 12 is configured as an isotropic high-strength fiber fabric, which has high specific strength, cutting resistance, wear resistance, and high temperature resistance, etc. in addition to the characteristics of light weight and flexibility, and has a wide range of applications in space structures. The reinforcing layer 12 is isotropic, so that the strength of the reinforcing layer 12 is the same everywhere, and the internal air pressure can be withstood at each position, and there is no weak point, so the safety is high. In order to meet the requirements of light weight, high strength and flexibility, etc., specifically, the reinforcing layer 12 can be made of aramid fiber, liquid crystal fiber, etc., which can withstand the internal air pressure of the flexible skin structure 10 and provide effective protection for the sealed air bag layer 11.

[0055] Further, according to some embodiments of the present application, the reinforcing layer 12 uses a multi-directional woven fabric or a multi-layer flat-woven fabric laid at different angles. In this embodiment, the reinforcing layer 12 uses a multi-directional woven fabric or a multi-layer flat-woven fabric laid at different angles, that is, multi-axial cloth or layer design can be used. Specifically, the reinforcing layer 12 can be designed by using a flexible aramid fiber composite coating fabric layer. This embodiment can ensure the isotropy of the reinforcing layer 12, ensure that the strength of the reinforcing layer 12 is the same in all directions, ensure that the internal air pressure can be withstood at each position of the reinforcing layer 12, and there is no weak point, so the safety is high. In some embodiments, the multi-layer fiber fabric can be combined together by flexible resin, coating material or flexible adhesive; among them, special coating materials such as high phenyl silicone rubber and fluororubber, etc. can be used to cope with the requirements of super-low temperature, large temperature difference and anti-radiation aging on the moon, and the durability of the fabric can be enhanced.

[0056] According to some embodiments of the present application, the flexible skin structure 10 further comprises a protective layer 13 arranged on the outer surface of the reinforcing layer 12 to protect the reinforcing layer 12 and the sealed air bag layer 11. In this embodiment, the protective layer 13 is arranged on the outer surface of the reinforcing layer 12, which can protect the sealed air bag layer 11 and the reinforcing layer 12, avoid the direct exposure of the reinforcing layer 12 to the environment, slow down the aging process of the reinforcing layer 12 and the sealed air bag layer 11, and at the same time, prevent scratching and wear. In some embodiments, the protective layer 13 can be configured as a molded coating, which can improve the sealing performance, prevent the flexible skin structure 10 from being punctured and leaking, and thus improve the safety of the structure.

[0057] In some embodiments, the adhesive is used to bond between the layers of the flexible skin structure 10, and the specific functional layers can be adjusted according to the requirements of the use conditions and environment.
