Description

Technical Field

[0001] This invention belongs to the field of substation technology, specifically relating to a variable compartment structure for a box-type substation based on origami engineering. Background Technology

[0002] Prefabricated substations integrate core components such as high-voltage switches, transformers, and low-voltage distribution equipment into one unit. With their advantages of short construction cycles and flexible mobility, they are widely used in urban power distribution, rural power coverage, and construction site applications. The prefabricated substation's cabin structure, as the foundation for the equipment, directly determines its ease of transportation and spatial adaptability.

[0003] Currently, the cabin structure of prefabricated substations mostly adopts a fixed-size design or a modular assembly design. In the fixed-size design, the side panels, top panel, and bottom panel are all integrally formed or fixedly connected structures. Once the internal space of the cabin is formed, it cannot be adjusted later. This structure is easily restricted during transportation, and even if transported separately, the large dimensions of each side wall make on-site assembly difficult. Modular designs divide the cabin structure into multiple modules according to different functions. These modules can be transported independently and assembled on-site, reducing transportation difficulty to some extent. However, the dimensions of each module are still fixed, and the overall cabin structure after assembly cannot be flexibly adjusted to adapt to spatial changes in different scenarios.

[0004] It is evident that the existing cabin structures cannot meet the ever-changing space requirements of existing prefabricated substations during use, and there are certain transportation difficulties. For example, adopting a separate transportation method to reduce transportation difficulties indirectly increases the difficulty of loading and unloading. Summary of the Invention

[0005] This invention provides a variable compartment structure for a prefabricated substation based on origami engineering, aiming to solve the technical problems that the existing compartment structure of prefabricated substations cannot meet diverse space usage requirements, and that splitting the substation for transportation would increase loading and unloading difficulties in order to reduce transportation costs.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a variable compartment structure for a box-type substation based on origami engineering is provided, including a top plate, a bottom plate, a first side plate, a second side plate, a third side plate, and a fourth side plate. The first side plate and the second side plate are arranged opposite each other and have equal projected areas. The third side plate and the fourth side plate are arranged opposite each other and have equal projected areas. The first side plate, the second side plate, the top plate, and the bottom plate are all folded structures. The third side plate and the fourth side plate are each an integral plate structure. The projected area of ​​the third side plate is smaller than the projected area of ​​the first side plate. The variable cabin structure of the box-type substation in the origami project also includes a support assembly connecting the third side plate and the fourth side plate, and the support assembly is a telescopic structure; The cabin structure has a folded state and an unfolded state. When it is in the folded state, the top plate, the bottom plate, the first side plate, and the second side plate are folded. When it is in the unfolded state, the top plate, the bottom plate, the first side plate, and the second side plate are partially or completely unfolded.

[0007] In one possible implementation, the top plate, the bottom plate, the first side plate, and the second side plate each include a plurality of plate units arranged in sequence, and a connector connecting two adjacent plate units. The connector includes two parallel rotating shafts and a connector head at the end of the rotating shafts. The two rotating shafts are respectively rotatably engaged with two adjacent plate units, and each connector head is fixedly connected to the end of the two rotating shafts.

[0008] In one possible implementation, first magnets are provided on the upper and lower sides of the first side plate and the second side plate, the distribution direction of the first side plate and the second side plate is defined as a first direction, and second magnets are provided on the opposite sides of the top plate and the bottom plate located in the first direction. When the cabin structure is in the deployed state, the first magnet located at the top is magnetically fixed to the second magnet on the top plate, and the first magnet located at the bottom is magnetically fixed to the second magnet on the bottom plate.

[0009] In one possible implementation, the sidewall of the plate unit is provided with a groove, and two adjacent grooves of two adjacent plate units enclose each other to form a mounting groove, and the connector is located in the mounting groove.

[0010] In one possible implementation, the support assembly includes a main body and telescopic tube assemblies that are slidably fitted to both ends of the main body; The telescopic tube assembly includes multiple nested and slidably fitted secondary tubes. The secondary tube with the largest diameter is slidably fitted with the central hole of the main tube. One of the secondary tubes with the smallest diameter is fixed to the third side plate at one end away from the main tube, and another secondary tube with the smallest diameter is fixed to the fourth side plate at one end away from the main tube.

[0011] In one possible implementation, an adjustment plate is also included, located between the third side plate and the fourth side plate, for adjusting the position along the extension and retraction direction of the support assembly.

[0012] In one possible implementation, the adjusting plate has a sliding hole that slides with the support assembly, and the adjusting plate has a clamping arm that extends radially along the sliding hole and abuts against the outer peripheral surface of the support assembly.

[0013] In one possible implementation, the adjusting plate has a receiving groove located on the outer periphery of the sliding hole, the clamping arm slides radially into the receiving groove, and the sidewall of the sliding hole has a through hole for the clamping arm to extend out. An abutment spring is also provided between the side wall of the receiving groove and the clamping arm, and the abutment spring has a preload force that causes the clamping arm to abut against the outer peripheral surface of the support assembly.

[0014] In one possible implementation, the adjustment plate is provided with a plug rod on the side near the first side plate and the side near the second side plate, one end of the plug rod is rotatably connected to the adjustment plate, and the first side plate and the second side plate are provided with a plug hole corresponding to the plug rod.

[0015] In one possible implementation, the third or fourth side plate is provided with a lifting ring, and the adjustment plate is provided with a hook for connecting to the lifting ring.

[0016] The solution shown in this application embodiment, compared with the prior art, features a folded cabin structure. In this folded state, the distance between the third and fourth side panels is minimized, and the top, bottom, first, and second side panels are all retracted and folded. This results in a minimal overall cabin volume, conforming to the size range of conventional transport vehicles, eliminating the need for disassembly for transport. The folded cabin structure is smaller than existing fixed or modular cabin structures, facilitating transport and reducing costs. The cabin requires no assembly; it can be partially or fully unfolded according to usage requirements. Furthermore, the support components between the unfolded third and fourth side panels provide stable support, enhancing its applicability and safety. Attached Figure Description

Detailed Implementation

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] Please refer to the following: Figures 1 to 9 The variable compartment structure of the box-type substation based on origami engineering provided by the present invention will now be described.

[0021] The variable compartment structure of the prefabricated substation based on origami engineering includes a top plate 10, a bottom plate 11, a first side plate 12, a second side plate 13, a third side plate 14, and a fourth side plate 15. Multiple side plates are connected between the top plate 10 and the bottom plate 11. The first side plate 12 and the second side plate 13 are arranged opposite each other and have equal projected areas. The third side plate 14 and the fourth side plate 15 are arranged opposite each other and have equal projected areas. The first side plate 12, the second side plate 13, the top plate 10, and the bottom plate 11 are all folded structures. The third side plate 14 and the fourth side plate 15 are each an integral plate structure. The projected area of ​​the third side plate 14 is smaller than the projected area of ​​the first side plate 12.

[0022] Here, we take the first side panel 12 and the second side panel 13 as the left and right side panels, and the third side panel 14 and the fourth side panel 15 as the front and rear side panels for illustration. The two side panels with smaller areas are designed as integral panels, while the rest are designed as folding panel structures, which can minimize the space occupied after folding, thereby reducing the difficulty of transportation.

[0023] It should be noted that although the names of the top plate 10 and the bottom plate 11 include the direction, this direction is only used to facilitate the description of the position of each plate. In actual use, the top plate 10 is not necessarily used as the top plate 10, but can also be used as a side plate.

[0024] The variable cabin structure of the box-type substation of the origami project also includes a support component 20, which is connected between the third side plate 14 and the fourth side plate 15. The support component 20 is a telescopic structure.

[0025] Optionally, the support assembly 20 can be an existing hydraulic telescopic system or a continuously nested telescopic tube structure.

[0026] The cabin structure has a folded state and an unfolded state. When it is in the folded state, the top plate 10, bottom plate 11, first side plate 12 and second side plate 13 are all folded. When it is in the unfolded state, the top plate 10, bottom plate 11, first side plate 12 and second side plate 13 are partially or fully unfolded.

[0027] It is easy to imagine that when the cabin structure is deployed, the support assembly 20 can be extended and retracted to adjust the distance between the third side plate 14 and the fourth side plate 15, and its length can be fixed after adjustment, thereby ensuring that the distance between the third side plate 14 and the fourth side plate 15 is fixed and will not move during use.

[0028] As described below, for example, the first side panel 12 includes 6 panel units 30. When only 3 panel units 30 are unfolded and the other 3 panel units 30 are folded, the area covered by the 3 unfolded panel units 30 is used as the installation area of ​​the power distribution equipment.

[0029] In practical applications, openable doors and ventilation windows can be machined on the third side plate 14 and the fourth side plate 15 to facilitate the installation of equipment inside after unfolding.

[0030] The origami-based variable compartment structure for a prefabricated substation provided in this embodiment, compared with existing technologies, features a folded compartment structure. In this folded state, the distance between the third side plate 14 and the fourth side plate 15 is minimized, and the top plate 10, bottom plate 11, first side plate 12, and second side plate 13 are all in a retracted folded state. This results in a minimal overall volume of the compartment, conforming to the size range of conventional transport vehicles, eliminating the need for disassembly for transport. The folded compartment structure is smaller than existing fixed or modular compartment structures, facilitating transport and reducing costs. The compartment requires no assembly; it can be partially or fully unfolded according to usage requirements. Furthermore, the support assembly 20 provides stable support between the unfolded third side plate 14 and the fourth side plate 15, enhancing its applicability and safety.

[0031] The cabin structure of this application can quickly switch between storage and use modes by unfolding and folding. The overall structure is simple to operate, reducing assembly difficulty and labor costs. It is also flexible in operation and can meet the needs of different scenarios for different spaces, solving the problem that existing cabin structures are difficult to adapt to needs.

[0032] In some embodiments, a specific implementation of the top plate 10, bottom plate 11, first side plate 12, and second side plate 13 may adopt the following approach: Figures 3 to 4 and Figure 6 The structure shown is as follows. The top plate 10, bottom plate 11, first side plate 12 and second side plate 13 each include a plurality of plate units 30 arranged in sequence, and a connector 40 connecting two adjacent plate units 30. The connector 40 includes two parallel rotating shafts 42 and a connector head 41 provided at the end of the rotating shaft 42. The two rotating shafts 42 are respectively rotatably engaged with two adjacent plate units 30, and each connector head 41 is rotatably connected to the end of the two rotating shafts 42.

[0033] It should be noted that the plate unit 30 is also connected to the third side plate 14 and to the fourth side plate 15 via connectors 40. Taking the connector 40 between the third side plate 14 and the plate unit 30 as an example, one of the pivots 42 in the plate unit 30 is rotatably connected to the third side plate 14, and the other is rotatably connected to the plate unit 30. Similarly, the connector 40 between the fourth side plate 15 and the plate unit 30 consists of one pivot 42 rotatably connected to the fourth side plate 15 and the other rotatably connected to the plate unit 30.

[0034] It is easy to conceive that, in order to avoid interference between the first side plate 12, the second side plate 13, the top plate 10, and the bottom plate 11 during folding, the first side plate 12 and the second side plate 13 can be folded outwards (i.e., the first side plate 12 is folded away from the second side plate 13, and the second side plate 13 is folded away from the first side plate 12), and the top plate 10 and the bottom plate 11 can be folded inwards (i.e., the top plate 10 is folded downwards, and the bottom plate 11 is folded upwards); or the first side plate 12 and the second side plate 13 can be folded inwards (i.e., the first side plate 12 is folded close to the second side plate 13, and the second side plate 13 is folded close to the first side plate 12), and the top plate 10 and the bottom plate 11 can be folded outwards (i.e., the top plate 10 is folded upwards, and the bottom plate 11 is folded downwards); or the first side plate 12, the second side plate 13, the top plate 10, and the bottom plate 11 can all be folded outwards.

[0035] This embodiment uses multiple sequentially connected plate units 30 to replace the traditional large-size plate structure. The weight of each plate unit 30 is reduced, and the operating resistance is reduced during folding, making the folding process more effortless. The connector 40, which is composed of two rotating shafts 42, ensures that it rotates along a fixed axis during folding, avoiding skewing, jamming, or other issues during folding.

[0036] The first side plate 12, the second side plate 13, the top plate 10, and the bottom plate 11 are all divided into multiple plate units 30, which can be partially or completely folded (or unfolded). The structure of the cabin can be flexibly adjusted according to the needs of the site, adapting to the installation space of different power distribution equipment. Moreover, the volume after folding is smaller, meeting the requirements of transportation scenarios for small size and easy handling, and solving the problem of limited transportation of traditional fixed cabins.

[0037] When the plate unit 30 is in the unfolded state, its plate surface is continuous and perpendicular to the third side plate 14 and the fourth side plate 15; correspondingly, when the plate unit 30 is in the folded state, its plate surfaces are parallel to each other and stacked.

[0038] In some embodiments, an improved implementation of the above-described cabin structure may employ, as follows: Figure 4 The structure shown is as follows. First magnets 50 are provided on the upper and lower sides of the first side plate 12 and the second side plate 13. The distribution direction of the first side plate 12 and the second side plate 13 is defined as the first direction. Second magnets 51 are provided on the opposite sides of the top plate 10 and the bottom plate 11 located in the first direction.

[0039] When the cabin structure is in the deployed state, the first magnet 50 located at the top is magnetically attracted and fixed to the second magnet 51 on the top plate 10, and the first magnet 50 located at the bottom is magnetically attracted and fixed to the second magnet 51 on the bottom plate 11.

[0040] It is easy to imagine that the first magnet 50 at the top of the first side plate 12 and the first magnet 50 at the top of the second side plate 13 are magnetically fixed to the second magnets 51 on opposite sides of the top plate 10; the first magnet 50 at the bottom of the first side plate 12 and the first magnet 50 at the bottom of the second side plate 13 are magnetically fixed to the second magnets 51 on opposite sides of the bottom plate 11.

[0041] In specific implementation, the plate units 30 of the top plate 10, bottom plate 11, first side plate 12, and second side plate 13 have the same width, thereby ensuring that when in the unfolded state, the plate units 30 on the top plate 10 correspond one-to-one with the plate units 30 on the first side plate 12 and the second side plate 13, thereby ensuring the correspondence of the positions of the first magnet 50 and the second magnet 51.

[0042] In this embodiment, the magnetic attraction structure forms a preset alignment reference. When unfolded, the side plates can automatically attract and align with the top plate 10 and the bottom plate 11, eliminating the need for repeated manual calibration. A first magnet 50 is provided on each plate unit 30 of the first side plate 12 and the second side plate 13, and a second magnet 51 is provided on each plate unit 30 of the top plate 10 and the bottom plate 11. This replaces traditional fasteners for quick locking, reducing assembly complexity. The upper and lower sides of the first side plate 12 and the second side plate 13 are magnetically fixed, as are the opposite sides of the top plate 10 and the bottom plate 11. Each plate can form constraints in two directions, significantly improving the overall stability of the cabin structure and preventing deformation caused by single-point stress.

[0043] To ensure that the adjacent plate units 30 can fit tightly together after the first side plate 12, the second side plate 13, the top plate 10 and the bottom plate 11 are magnetically attracted, the first magnet 50 and the second magnet 51 can be installed in the plate unit 30 by means of embedded installation.

[0044] In practical use, to achieve waterproof and dustproof effects, there will be splicing gaps between the first side plate 12, the second side plate 13, the top plate 10, and the bottom plate 11 due to the rotatable connection between the plate structures via connectors 40. After unfolding and assembly, a protective layer can be covered or pasted on its outer perimeter. This type of waterproofing measure is more cost-effective. Furthermore, after assembly, waterproof adhesive can be used to seal the gaps.

[0045] In some embodiments, an improved implementation of the above-described plate unit 30 may employ, as follows: Figure 4 The structure is shown. The side wall of the plate unit 30 is provided with a groove 31. Two adjacent grooves 31 of two adjacent plate units 30 are surrounded to form a mounting groove, and the connector 41 is located in the mounting groove.

[0046] It is easy to imagine that the grooves 31 on the first side plate 12 and the second side plate 13 are located at the top and bottom of the plate unit 30, respectively. Taking the top groove 31 as an example, the grooves 31 on the top of two adjacent plate units 30 fit together, so that each groove 31 can accommodate half of the connector 41.

[0047] In order to reduce the gaps after the first side plate 12, the second side plate 13, the top plate 10 and the bottom plate 11 are assembled, the size of the mounting groove can be close to the size of the connector 41. That is, when the plate unit 30 is folded and unfolded, the connector 41 can move freely in the mounting groove, while ensuring that there are not too large gaps.

[0048] In this embodiment, the mounting groove formed by the recess 31 of the plate unit 30 is used to accommodate the connector 41, ensuring that there are no protruding structures on the side walls of adjacent plate structures, thus guaranteeing the neatness and aesthetics of the appearance. At the same time, the flush side can improve the waterproof and dustproof performance of the cabin structure, and when used in conjunction with the aforementioned protective layer, it can extend the service life.

[0049] The mounting slot is used for mounting the connector 41. During assembly, the connector 41 can be positioned, and the shaft 42 on the connector 41 can be aligned with the hole on the board unit 30, reducing assembly difficulty and saving assembly time.

[0050] In some embodiments, a specific implementation of the support component 20 described above may employ, as follows: Figures 5 to 6 The structure is shown. The support assembly 20 includes a main body 21 and telescopic tube assemblies that are slidably fitted at both ends of the main body 21.

[0051] The telescopic tube assembly includes multiple secondary tube bodies 22 that are nested and slidably fitted in sequence. The secondary tube body 22 with the largest diameter is slidably fitted with the central hole of the main tube body 21. One of the secondary tube bodies 22 with the smallest diameter has its end opposite to the main tube body 21 fixedly connected to the third side plate 14. Another secondary tube body 22 with the smallest diameter has its end opposite to the main tube body 21 fixedly connected to the fourth side plate 15.

[0052] When the entire cabin structure is in a folded state, both telescopic tube assemblies are located inside the main tube 21; when the entire cabin structure is partially or fully deployed, the extension length of each secondary tube 22 is adjusted as needed, so that the length of the entire support assembly 20 is equal to the distance between the third side plate 14 and the fourth side plate 15 after deployment.

[0053] Specifically, the main tube 21 and the secondary tube 22 need to be fixed after adjustment. The specific fixing method can be as follows: (1) Static friction fixation. By controlling the sliding tight fit between the main tube 21 and the secondary tube 22, and between the secondary tubes 22, the static friction force during the sliding process is used to maintain the fixed position after expansion and contraction.

[0054] (2) Fixing the positioning rod. By setting holes on the main tube 21 and the secondary tube 22, multiple holes are evenly distributed along the circumference. After sliding adjustment to the appropriate position, the positioning rod is inserted into the corresponding hole between the main tube 21 and the secondary tube 22, and between the secondary tubes 22, to lock the current extension state.

[0055] (3) Ball bearing fixing. By setting a ball bearing that can extend and retract radially on the secondary tube 22, the ball bearing is driven by a spring; the secondary tube 22 and the main tube 21 are provided with positioning grooves corresponding to the ball bearing. When the ball bearing slides to the appropriate position, the spring pushes the ball bearing into the corresponding positioning groove to lock the current extension and retraction state.

[0056] It is easy to imagine that, in order to prevent the secondary tube 22 from coming out, the secondary tube 22 can be limited by the shoulder between the secondary tubes 22 and between the secondary tube 22 and the main tube 21.

[0057] This embodiment employs a multi-stage nested telescopic structure consisting of a main tube 21 and secondary tubes 22. Telescopic tube assemblies are installed on both sides of the main tube 21, effectively extending the telescopic stroke and adapting to changes in the spacing between the third side plate 14 and the fourth side plate 15 during cabin structure deployment. By installing telescopic tube assemblies at both ends of the main tube 21, compared to continuous nested telescopic tubes, insufficient support due to the smaller diameter of the outermost secondary tube 22 is avoided, ensuring the support effect of the support assembly 20 and improving the safety of the cabin structure.

[0058] In some embodiments, an improved implementation of the above-described cabin structure may employ, as follows: Figures 5 to 6 The structure shown also includes an adjustment plate 60, located between the third side plate 14 and the fourth side plate 15, for adjusting the position along the extension and retraction direction of the support assembly 20.

[0059] The adjustment plate 60 is also an integral plate structure. When the cabin structure is partially unfolded, the adjustment plate 60 can be adjusted to the end of the unfolded plate unit 30. The space between the adjustment plate 60 and the third side plate 14 is the power distribution space, used to install power distribution equipment. When the cabin structure is fully unfolded, the adjustment plate 60 can be adjusted to fit against the fourth side plate 15.

[0060] Alternatively, the space between the adjustment plate 60 and the fourth side plate 15 is the power distribution space, and the space between the adjustment plate 60 and the third side plate 14 is the folding space; when the cabin structure is fully unfolded, the adjustment plate 60 is adjusted to fit against the third side plate 14.

[0061] It is easy to imagine that even when fully extended, the adjustment plate 60 can be adjusted to be spaced apart from the third side plate 14 and the fourth side plate 15, thereby dividing the internal space of the entire cabin structure into two independent parts. Furthermore, by adjusting the position of the adjustment plate 60, the volume of each of the two independent spaces can be flexibly changed to meet different power distribution needs.

[0062] In this embodiment, by adding an adjustment plate 60, the un-deployed plate unit 30 can be covered behind the cabin structure when it is deployed, thereby ensuring that no protruding plate unit 30 appears between the adjustment plate 60 and the third side plate 14. The folded plate unit 30 will not interfere with the internally installed power distribution equipment, thus extending the service life of the power distribution equipment.

[0063] It should be noted that the adjusting plate 60 slides in conjunction with the support assembly 20, thereby enabling flexible position adjustment. For example, a groove can be provided on the support assembly 20, and the adjusting plate 60 has a slider that extends into the groove.

[0064] In some embodiments, a specific connection method between the adjustment plate 60 and the support component 20 may be as follows: Figure 5 The structure shown is as follows. The adjusting plate 60 has a sliding hole that slides with the support assembly 20. The adjusting plate 60 is provided with a clamping arm 61, which extends radially along the sliding hole and is used to abut against the outer peripheral surface of the support assembly 20.

[0065] The support assembly 20 includes a main tube 21 and a secondary tube 22. When the adjusting plate 60 slides to different tube positions, the distance between the side wall of the sliding hole and the outer circumferential surface of the tube is different. In order to ensure that the adjusting plate 60 can be stably fixed in any position, a clamping arm 61 is provided. The clamping arm 61 can be extended and retracted to adapt to different distances and always abuts against the outer circumferential surface of the support assembly 20, thereby fixing the position of the adjusting plate 60 and meeting the positioning requirements of flexible spatial division.

[0066] In some embodiments, a specific installation method for the clamping arm 61 described above can be as follows: Figure 5 The structure shown is as follows. The adjusting plate 60 has a receiving groove located on the outer periphery of the sliding hole. The clamping arm 61 slides radially into the receiving groove along the sliding hole. The side wall of the sliding hole has a through hole for the clamping arm 61 to extend out. An abutment spring 62 is also provided between the side wall of the receiving groove and the clamping arm 61. The abutment spring 62 has a preload force that causes the clamping arm 61 to abut against the outer peripheral surface of the support assembly 20.

[0067] The abutment spring 62 continuously provides radial preload, causing the clamping arm 61 to automatically abut against the outer periphery of the support assembly 20. Compared to fixing methods such as bolts and pins, this method is more convenient to operate. The spring provides clamping force, which creates a frictional self-locking between the clamping arm 61 and the support assembly 20, preventing the adjusting plate 60 from shifting during use. When moving the adjusting plate 60, tools can be used to overcome the preload of the abutment spring 62, reducing friction with the support assembly 20 and minimizing wear on the support assembly 20.

[0068] To improve the connection stability between the adjusting plate 60 and the support assembly 20, multiple clamping arms 61 can be evenly arranged along the circumference of the sliding hole. Correspondingly, receiving grooves and abutment springs 62 also need to be set accordingly.

[0069] In some embodiments, an improved connection method between the adjustment plate 60 and the side plate strip can be as follows: Figure 5 The structure shown is as follows. The side of the adjusting plate 60 near the first side plate 12 and the side of the adjusting plate 60 near the second side plate 13 are both provided with a plug rod 63. One end of the plug rod 63 is rotatably connected to the adjusting plate 60. The first side plate 12 and the second side plate 13 are both provided with a plug hole 32 corresponding to the plug rod 63.

[0070] After unfolding, the insertion rod 63 on the adjustment plate 60 is inserted into the corresponding insertion hole 32 on the side plate, which not only restrains the adjustment plate 60 from displacement, but also ensures that the plate units 30 will not fold on their own during use.

[0071] The clamping arm 61 grips the support assembly 20, and the insertion rod 63 engages with the insertion hole 32. This dual fixing method further enhances the stability of the adjusting plate 60 after it is fixed, thus preventing it from moving on its own during use. After the insertion rod 63 engages with the insertion hole 32, it also limits the first side plate 12 and the second side plate 13, preventing the deployed plate unit 30 from folding on its own, ensuring the strength and safety of the cabin structure. The insertion rod 63 connects to the adjusting plate 60 by rotation, allowing it to fold without interfering with adjacent structures when the adjusting plate 60 is being adjusted. After the adjusting plate 60 is adjusted, it unfolds for easy connection with the adjacent insertion hole 32, ensuring convenient use and a smooth deployment process.

[0072] It should be noted that when both the first side plate 12 and the second side plate 13 include multiple plate units 30, each plate unit 30 can be provided with a socket 32, so that after unfolding, the adjustment plate 60 can be connected to the socket 32 ​​on the plate unit 30 corresponding to whichever plate unit 30 it corresponds to.

[0073] To facilitate the storage of the insertion rod 63, a receiving groove can be provided on the side wall of the adjusting plate 60, and the insertion rod 63 is rotatably connected to the side wall of the receiving groove. When the insertion rod 63 is folded, it can be located in the receiving groove, thereby preventing it from protruding from the side of the adjusting plate 60.

[0074] When the insert rod 63 is provided, the side wall of the adjustment plate 60 with the insert rod 63 needs to have a certain gap with the plate unit 30. The insertion hole 32 on the plate unit 30 can extend downward at an angle to facilitate the extension of the insert rod 63 on the adjustment plate 60 and its engagement with the insertion hole 32.

[0075] As a modified implementation, in order to reduce the gap between the adjusting plate 60 and the plate unit 30, a magnetic attraction structure can be provided on the plate unit 30, and a retractable magnetic block can be provided on the adjusting plate 60. When the adjusting plate 60 moves to the point where the magnetic block corresponds to the magnetic attraction structure, the magnetic block extends into the slot of the magnetic attraction structure to achieve the positioning of the adjusting plate 60. A handle is fixed to the magnetic block and extends out of the adjusting plate 60. The adjusting plate 60 is also provided with a sliding groove for the handle to slide. When it is necessary to unlock the adjusting plate 60, the handle is pushed to move the magnetic block away from the magnetic attraction structure.

[0076] It is easy to imagine that the magnetic structure could be a magnet.

[0077] In some embodiments, an improved implementation of the adjustment plate 60 may employ, as follows: Figure 6 The structure is shown. A lifting ring 70 is provided on the third side plate 14 or the fourth side plate 15, and a hook 64 for connecting to the lifting ring 70 is provided on the adjusting plate 60.

[0078] When the adjustment plate 60 and the third side plate 14 enclose a power distribution space, a lifting ring 70 is installed on the fourth side plate 15; when the adjustment plate 60 and the fourth side plate 15 enclose a power distribution space, a lifting ring 70 is installed on the third side plate 14.

[0079] Since it is not necessarily fully unfolded during use, when it is partially unfolded, the hook 64 on the adjustment plate 60 is connected to the lifting ring 70 on the third side plate 14 or the fourth side plate 15. The connected lifting ring 70 and hook 64 can be used as a safety device to prevent the folded part from unfolding on its own during use.

[0080] Since the distance between the hook 64 and the lifting ring 70 may be different in different folding states, the hook 64 and the adjusting plate 60 can be connected by a detachable chain. Different length chains can be replaced in different states to adapt to the changes in the distance between the hook 64 and the lifting ring 70. After the hook 64 and the lifting ring 70 are connected, the chain is in a taut state, and the tension of the chain on the adjusting plate 60 will not overcome the clamping force of the clamping arm 61 on the support component 20, thereby ensuring the stability of the position of the adjusting plate 60.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
