[0052] To solve the above technical problems, the embodiment of the present application provides a foldable space cabin, which comprises a shell, two connecting assemblies, two folding assemblies, a plurality of supporting rods and a circumferential supporting assembly. The shell is provided with two oppositely arranged openings, and the connecting assemblies are connected to the edges of the openings. The folding assemblies are located inside the shell and are fixedly connected with the connecting assemblies. When one end of the folding assembly is unfolded towards the shell, the shell is in an unfolded state, and when one end of the folding assembly is retracted away from the shell, the shell is in a retracted state. The supporting rods are located inside the shell, and the two ends of each supporting rod are connected with the folding assemblies. The circumferential supporting assembly is slidably arranged on the supporting rods and supports the shell during the folding process of the folding assemblies. In this way, the foldable space cabin provided by the present application can realize the unfolded state and the retracted state of the space cabin through the folding assemblies, and has the advantages of small volume, light weight, low cost, etc. The space cabin is transported in a folded form, which can save a lot of space for the rocket and reduce the launch cost.

[0053] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.
[0054] The embodiment of the present application provides a foldable space cabin, which realizes the unfolded state and the retracted state of the space cabin through the folding assemblies, has the advantages of small volume, light weight, low cost, etc. The space cabin is transported in a folded form, which can save a lot of space for the rocket and reduce the launch cost. The connecting assemblies, folding assemblies and circumferential supporting assemblies in the space cabin can provide rigidity for the space cabin, so that the space cabin has certain additional carrying capacity. The specific structure of the foldable space cabin provided by the embodiment of the present application will be introduced below with reference to the drawings.
[0055] Reference Figure 1 and Figure 2In an embodiment, the folding space cabin 100 can include a shell 200, a connecting assembly 300, a folding assembly 400, a support rod 500, and a circumferential support assembly 600. In a possible implementation, the number of the connecting assembly 300 and the folding assembly 400 can be at least two, and the number of the support rod 500 can be several. The number of the connecting assembly 300, the folding assembly 400, and the support rod 500 is not limited in the present application. In the present embodiment, the number of the connecting assembly 300 and the folding assembly 400 is taken as an example of two. Two openings 210 are formed on the shell 200, and the two openings 210 can be oppositely arranged. In a possible implementation, the two connecting assemblies 300 correspond to the two openings 210 respectively, and the two connecting assemblies 300 are connected to the edges of the two openings 210 respectively. For example, the connecting assembly 300 can be in a ring structure, and the opening 210 of the shell 200 can be in communication with the hollow part of the connecting assembly 300 in the ring structure, so that the connecting assembly 300 is in communication with the inside of the shell 200.
[0056] With reference to the above embodiment, Figure 2 In the above embodiment, the two folding assemblies 400 can be located inside the shell 200. The two folding assemblies 400 can correspond to the two connecting assemblies 300 respectively, and the two folding assemblies 400 are fixedly connected to the corresponding connecting assemblies 300 respectively. In the present embodiment, Figure 2 The folding space cabin 100 is in an unfolded state, Figure 3 The folding space cabin 100 is in a folded state. When one end of the folding assembly 400 is unfolded towards the shell 200, the shell 200 is in the unfolded state, and when one end of the folding assembly 400 is folded away from the shell 200, the shell 200 is in the folded state. It can be understood that the folding space cabin 100 can be unfolded with the unfolding of the folding assembly 400, and can be folded with the folding of the folding assembly 400.
[0057] With reference to the above embodiment, Figure 2 and Figure 3On the basis of the above embodiment, the plurality of support rods 500 can be located inside the shell 200, and two ends of each support rod 500 are connected with the folding assembly 400 respectively. It can be understood that one end of the support rod 500 is connected with one of the folding assemblies 400, and the other end of the support rod 500 is connected with another folding assembly 400. In a possible implementation, the circumferential support assembly 600 is slidably arranged on the support rod 500, and the circumferential support assembly 600 can be supported on the shell 200 in the folding process of the folding assembly 400. In the embodiment of the present application, the spacing between the plurality of support rods 500 is different when the folding assembly 400 is in the unfolded state or the contracted state, and the circumferential support assembly 600 adjusts the position by sliding on the support rod 500 to adapt to the support rods 500 with different spacing. In this way, the connecting assembly 300, the folding assembly 400, the support rod 500 and the circumferential support assembly 600 jointly form the frame of the folding space cabin 100, which has a certain supporting effect on the shell 200.
[0058] Reference Figure 4 In the implementation of the embodiment of the present application, each connecting assembly 300 can include a first connecting piece 310, a second connecting piece 320 and a fixing piece 330. The first connecting piece 310 and the second connecting piece 320 can be fixedly connected through the folding assembly 400. In a possible implementation, the first connecting piece 310 is connected with the edge of the opening 210 of the shell 200, the second connecting piece 320 is located on the side of the first connecting piece 310 facing the inside of the shell 200, and the fixing piece 330 can be located on the side of the first connecting piece 310 facing the second connecting piece 320 and is attached to the first connecting piece 310, and the fixing piece 330 is fixedly connected with the shell 200. It can be understood that the side of the first connecting piece 310 away from the second connecting piece 320 can be exposed to the shell 200, and the side of the first connecting piece 310 exposed to the shell 200 can be connected with the outer surface of the shell 200. Exemplarily, the first connecting piece 310 and the second connecting piece 320 can be two circular ring structures, and the centers of the first connecting piece 310 and the second connecting piece 320 are located on the same straight line.
[0059] Continuing to refer to Figure 4On the basis of the above-mentioned embodiments, each folding assembly 400 can comprise a first connecting rod 410, a second connecting rod 420 and a fixing base 430. In a possible implementation, the number of the first connecting rod 410, the second connecting rod 420 and the fixing base 430 can be several, and the present application does not limit the number of the first connecting rod 410, the second connecting rod 420 and the fixing base 430. It can be understood that the first connecting rod 410, the second connecting rod 420 and the fixing base 430 can form a folding mechanism, and several folding mechanisms are equidistantly arranged on the connecting assembly 300 with the center of the connecting assembly 300 as the center, and the several folding mechanisms collectively form the entire folding assembly 400. In the embodiments of the present application, the fixing base 430 is taken as an example, and the fixing base 430 can be located between the first connecting piece 310 and the second connecting piece 320, so that the first connecting piece 310 and the second connecting piece 320 are fixedly connected through the fixing base 430. In a possible implementation, the fixing base 430 can have a first end 431 and a second end 432, wherein the first end 431 of the fixing base 430 is fixedly connected with the first connecting piece 310, and the second end 432 of the fixing base 430 is fixedly connected with the second connecting piece 320. In addition, one end of the first connecting rod 410 and the first end 431 of the fixing base 430 can be rotatably connected, and the other end of the first connecting rod 410 and the support rod 500 can be rotatably connected. Correspondingly, one end of the second connecting rod 420 and the second end 432 of the fixing base 430 can be slidably connected, and the other end of the second connecting rod 420 and the first connecting rod 410 can be rotatably connected. In this way, the unfolded state and the folded state of the folding assembly 400 can be achieved.
[0060] With reference to the above Figure 4 On the basis of the above-mentioned embodiments, further, in a possible implementation, a groove 433 can be formed on the fixing base 430. One end of the second connecting rod 420 can be slidably located in the groove 433, so that the folding assembly 400 is in the unfolded state or the folded state. It can be understood that when one end of the second connecting rod 420 slides on the groove 433 to the second end 432 of the fixing base 430, the first connecting rod 410 is unfolded outward, so that the folding assembly 400 is in the unfolded state. When one end of the second connecting rod 420 slides on the groove 433 to the first end 431 of the fixing base 430, the first connecting rod 410 is folded inward, so that the folding assembly 400 is in the folded state.
[0061] With reference to the above Figure 2 , Figure 3 and Figure 4On the basis of the above embodiment, when the folding assembly 400 is in the unfolded state, the second connecting rod 420 is fixed to one side of the groove 433 close to the second end 432, and the first connecting rod 410 is arranged at an acute angle with the fixed seat 430. At this time, the first connecting rod 410, the second connecting rod 420 and the fixed seat 430 form a triangular structure, so that the folding assembly 400 is in a stable state, and the support effect on the shell 200 is better. In addition, when the folding assembly 400 is in the contracted state, the second connecting rod 420 can slide to one side of the groove 433 close to the first end 431. At this time, the first connecting rod 410, the second connecting rod 420 and the fixed seat 430 are in close contact, so that the folding assembly 400 is folded to the smallest form, and the volume occupied by the folding space cabin 100 is reduced.
[0062] With reference to the above embodiment, Figure 2 On the basis of the above embodiment, the two ends of the support rod 500 can be connected with the first connecting rod 410 in the two folding assemblies 400 respectively, so that the support rod 500, the two folding assemblies 400 and the two connecting assemblies 300 form the entire frame. In the axial direction, a plurality of support rods 500 can be arranged in parallel inside the shell 200. In the circumferential direction, a plurality of support rods 500 are arranged equidistantly on the folding assembly 400 with the center of the connecting assembly 300 in the form of a circular ring as the center, and each support rod 500 is rotatably connected with the first connecting rod 410. It can be understood that a plurality of support rods 500 can be connected with each other in the axial direction. The number of support rods 500 can be selected according to the needs of the folding space cabin 100, so that the folding space cabin 100 has different length sizes. Through the free splicing connection of a plurality of support rods 500, the adjustment of the axial size of the folding space cabin 100 is realized.
[0063] On the basis of the above embodiment, as shown in Figure 2 When the folding space cabin 100 is in the unfolded state, the support rod 500 rotates with the first connecting rod 410. At this time, the support rod 500 and the first connecting rod 410 are arranged at a certain angle, forming a stable support structure. As shown in Figure 3 When the folding space cabin 100 is in the contracted state, the support rod 500 rotates with the first connecting rod 410. At this time, the support rod 500 and the first connecting rod 410 are located on the same straight line, so that the folding space cabin 100 is contracted to the smallest form.
[0064] With reference to the above embodiment, Figure 5On the basis of the above-mentioned embodiment, the circumferential support assembly 600 can comprise a fixed block 610, a sliding block 620 and a rotating rod 630. In one possible implementation, the number of sliding blocks 620 can be at least four, and the number of rotating rods 630 can be at least two, which is not limited in the present application. In the embodiment of the present application, the number of sliding blocks 620 is four, and the number of rotating rods 630 is two. The fixed block 610 can be fixed to the support rod 500, and the fixed block 610 is fixed to one end of the support rod 500. The sliding block 620 is slidably arranged on the support rod 500, and when the sliding block 620 slides to the position where the fixed block 610 is located, the fixed block 610 can be used to limit the sliding position of the sliding block 620. In one possible implementation, two sliding blocks 620 can be slidably arranged on one support rod 500, and the other two sliding blocks 620 can be slidably arranged on the adjacent support rod 500. In addition, the two ends of the rotating rod 630 can be rotatably connected with the sliding blocks 620 located on the two support rods 500, and the two rotating rods 630 are cross arranged.
[0065] With reference to the above-mentioned embodiment, Figure 5 On the basis of the above-mentioned embodiment, the intersection of the two rotating rods 630 can be provided with a rotating part 631, so that the two rotating rods 630 can be rotatably connected through the rotating part 631. In this way, when the folding assembly 400 is in the unfolded state or the contracted state, the distance between the parallel arranged support rods 500 changes, and the sliding block 620 reciprocally slides on the support rod 500, thereby driving the rotating rod 630 to rotate. In the embodiment of the present application, the number of circumferential support assemblies 600 can be two, and the two circumferential support assemblies 600 are connected in the circumferential direction, thereby further enhancing the support performance of the circumferential support assembly 600.
[0066] On the basis of the above-mentioned embodiment, the inside of each sliding block 620 can be provided with a shaft holding device (not shown in the figure). The shaft holding device can be used to fix the sliding block 620 when the sliding block 620 slides to any position. In this way, after the sliding block 620 moves to the appropriate position, the shaft holding device is fixed to the sliding block 620, thereby achieving the purpose of enhancing the rigidity of the support rod 500.
[0067] On the basis of the above-mentioned embodiment, the shell 200 is made of flexible material. It can be understood that the shell 200 made of flexible material can have a certain elasticity, so that the folding space cabin 100 can be switched between the unfolded state and the contracted state.
[0068] In the embodiments of the present application, the folding space cabin 100 can realize the unfolding state and the shrinking state of the space cabin through the folding assembly 400, and has the advantages of small volume, light weight, low cost, etc. The space cabin is transported in a folded form, which can save a large amount of space for the rocket and reduce the launch cost. The connecting assembly 300, the folding assembly 400 and the circumferential support assembly 600 in the space cabin can provide rigidity for the space cabin, so that the space cabin has certain additional carrying capacity.
