Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a foldable modular box driven by light energy storage. Background Technology

[0002] With the rapid development of industrialized construction, higher requirements have been placed on the transportation efficiency and on-site assembly speed of facilities in temporary housing, emergency camps and various modular building projects.

[0003] Taking corridors as an example, current common corridor construction solutions still have many limitations in practical applications. In terms of construction efficiency, existing corridor structures typically require complex on-site work processes, with intricate and time-consuming assembly procedures. This often results in the corridor's construction speed lagging behind the deployment speed of the main building modules, becoming a bottleneck restricting the rapid delivery of the entire camp. Simultaneously, this work mode is highly dependent on human resources, and the transition from transportation to use often involves high labor intensity and operational safety risks. Regarding building quality and functionality, limited by the variable construction environment in the field, on-site assembled corridor structures often struggle to maintain a high degree of consistency in sealing performance, assembly precision, and structural stability, potentially posing safety hazards over long-term use.

[0004] Therefore, how to enable foldable and stackable transport containers to achieve rapid state transformation and reliable positioning upon arrival at the site, even with pre-loaded enclosure components, is a problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The main objective of this invention is to provide a foldable modular enclosure for photovoltaic energy storage drive in order to solve the above-mentioned technical problems.

[0006] The objective of this invention can be achieved by adopting the following technical solution:

[0007] A foldable modular enclosure driven by photovoltaic energy storage, comprising:

[0008] The first frame and the second frame are both formed by a top beam, a bottom beam and corner columns connecting the top beam and the bottom beam. The first frame or the second frame is provided with a functional panel, which includes one or more of a photovoltaic power generation curtain wall module, a folding and opening window module and a light-shielding curtain wall module.

[0009] Multiple folding beams connecting the first frame and the second frame;

[0010] One end of each of the folding beams is hinged to the first frame, and the other end is movably connected to the second frame via a connecting component. The connecting component is configured to drive the folding beam to rotate relative to the first frame to a preset angle when the second frame moves away from the first frame.

[0011] An unfolding drive assembly is provided, with its two ends hinged to the first frame and the folding beam, respectively. The unfolding drive assembly is configured to drive the folding beam to continue rotating relative to the first frame after the folding beam rotates to the preset angle, until the folding beam is perpendicular to the first frame and the second frame, respectively.

[0012] The beneficial technical effects of this invention are as follows: The foldable modular enclosure driven by photovoltaic energy storage provided by this invention, through the setting of foldable beams and corresponding connecting components and unfolding drive components, allows the enclosure to be folded into a flat configuration during transportation, significantly reducing the transportation height, facilitating multi-module stacking and transportation, and significantly improving transportation efficiency. Upon arrival at the construction site, only manual lifting of the second frame is required to rotate the folding beam to a preset angle. Then, the unfolding drive component automatically drives the folding beam to complete the remaining unfolding action, achieving rapid enclosure unfolding without complex on-site assembly operations, significantly shortening the construction cycle, and reducing labor intensity and operational safety risks. Simultaneously, functional panels can be pre-installed inside the frame in the factory, ensuring the assembly accuracy and sealing performance of the curtain wall, and improving the overall architectural quality of the enclosure.

[0026] Please also refer to Figures 1-6 This invention provides a foldable modular enclosure driven by photovoltaic energy storage, primarily used for rapid assembly and deployment in scenarios such as construction sites and emergency camps. The foldable modular enclosure is flattened and folded during transport for easy stacking; upon arrival at the site, it unfolds to form a three-dimensional structure. Specifically, the enclosure can be a corridor enclosure, comprising: a first frame 10 and a second frame 20, both formed by a top beam 31, a bottom beam 32, and corner posts 33 connecting the top beam 31 and the bottom beam 32. Functional panels are provided inside the first frame 10 or the second frame 20, including one or more of a photovoltaic power generation curtain wall module 41, a folding opening window module 42, and a light-shielding curtain wall module 43; multiple folding beams 50 connecting the first frame 10 and the second frame 20; and one end of each folding beam 50 hinged to the first frame 10. The other end is movably connected to the second frame 20 via a connecting component 60. The connecting component 60 is configured to drive the folding beam 50 to rotate relative to the first frame 10 to a preset angle when the second frame 20 moves away from the first frame 10. The unfolding drive component 70 is hinged at both ends to the first frame 10 and the folding beam 50, respectively. The unfolding drive component 70 is configured to drive the folding beam 50 to continue rotating relative to the first frame 10 after the folding beam 50 has rotated to the preset angle, until the folding beam 50 is perpendicular to the first frame 10 and the second frame 20, respectively.

[0027] In this embodiment, the foldable modular enclosure driven by photovoltaic energy storage mainly includes a first frame 10, a second frame 20, a folding beam 50, a connecting component 60, and an unfolding drive component 70.

[0028] The first frame 10 and the second frame 20 constitute the main support structure of the box body, located on opposite sides of the box body's unfolding direction. Both the first frame 10 and the second frame 20 are enclosed by a top beam 31, a bottom beam 32, and corner posts 33 connecting the top beam 31 and the bottom beam 32, forming a stable rectangular frame structure. In this embodiment, each frame includes one top beam 31, one bottom beam 32, and two corner posts 33, with the two corner posts 33 connected to the two ends of the top beam 31 and the bottom beam 32 respectively, thus forming a rectangular frame structure. Figure 2 As shown, the two ends of the corner post 33 can be connected to the corresponding top beam 31 and bottom beam 32 respectively through corner fitting boxes. The corner fitting boxes are provided with holes so that a crane can lift the box.

[0029] Functional panels are installed on the inner side of either the first frame 10 or the second frame 20. These functional panels can be installed on the inner facade of the frame to provide enclosure for the enclosure. The functional panels include one or more of the following: a photovoltaic power generation curtain wall module 41, a folding window module 42, and a light-shielding curtain wall module 43. The photovoltaic power generation curtain wall module 41 converts solar energy into electrical energy to power the electrical equipment within the enclosure; the folding window module 42 can be opened outwards for ventilation; and the light-shielding curtain wall module 43 can be made of metal or acrylic sheets to block sunlight or protect privacy. These three functional modules can be combined arbitrarily according to actual usage needs to form a curtain wall facade that meets different functional requirements such as lighting, ventilation, and power generation. Generally, the functional panels are pre-installed on only one frame, with the other frame serving as the interface for connection to the room.

[0030] Multiple folding beams 50 are connected between the first frame 10 and the second frame 20. These folding beams 50 serve to connect the two frames and support the top and bottom of the housing. Specifically, one end of each folding beam 50 is hinged to the first frame 10, allowing the folding beam 50 to rotate relative to the first frame 10 about the hinge point. The other end of the folding beam 50 is movably connected to the second frame 20 via a connecting assembly 60.

[0031] The design of the connecting component 60 enables the linkage between the change in distance between the two frames and the rotation angle of the folding beam 50. The connecting component 60 is configured such that when the second frame 20 moves away from the first frame 10 (i.e., the box begins to unfold), the connecting component 60 can move the other end of the folding beam 50, thereby forcing the folding beam 50 to rotate relative to the first frame 10. This process rotates the folding beam 50 from its folded state to a preset angle. This preset angle is an intermediate state during the unfolding process, providing a basis for subsequent full unfolding.

[0032] To achieve automated or semi-automated deployment of the enclosure and ensure proper deployment, this embodiment also includes a deployment drive assembly 70. The two ends of the deployment drive assembly 70 are hinged to the first frame 10 and the folding beam 50, respectively. The deployment drive assembly 70 is configured to provide auxiliary power. Specifically, its operating logic is as follows: when the folding beam 50 rotates to a preset angle via the aforementioned connecting assembly 60, the deployment drive assembly 70 applies a driving force, driving the folding beam 50 to continue rotating relative to the first frame 10 until the folding beam 50 rotates to a position perpendicular to both the first frame 10 and the second frame 20. At this point, the folding beam 50 is in a fully deployed state, the distance between the first frame 10 and the second frame 20 reaches its maximum, and the enclosure forms a stable three-dimensional spatial structure.

[0033] The foldable modular enclosure driven by photovoltaic energy storage provided in this embodiment, through the setting of foldable folding beams 50 and corresponding connecting components 60 and unfolding drive components 70, allows the enclosure to be folded into a flat configuration during transportation, significantly reducing the transportation height, facilitating multi-module stacking and transportation, and significantly improving transportation efficiency. Upon arrival at the construction site, only manual lifting of the second frame 20 is required to rotate the folding beams 50 to a preset angle. Then, the unfolding drive components 70 automatically drive the folding beams 50 to complete the remaining unfolding action, achieving automatic unfolding of the enclosure. No complex on-site assembly work is needed, significantly shortening the construction cycle and reducing labor intensity and operational safety risks. Simultaneously, functional panels can be pre-installed inside the frame in the factory, ensuring the assembly accuracy and sealing performance of the curtain wall, and improving the overall architectural quality of the enclosure. It is worth noting that even with the unfolding drive components 70, on-site operators can continue to lift the second frame 20 until the distance between the first frame 10 and the second frame 20 reaches its maximum, forming a stable three-dimensional spatial structure for the enclosure.

[0034] In one embodiment, the second frame 20 is provided with a guide rail 34, the connecting assembly 60 includes a slider 61 that cooperates with the guide rail 34 and a connecting rod assembly hinged to the slider 61, and the other end of the folding beam 50 is connected to the slider 61 through the connecting rod assembly.

[0035] In this embodiment, a guide rail 34 is provided on the second frame 20. The guide rail 34 extends along the height direction of the second frame 20, that is, along the height direction after the box is unfolded, and is fixedly installed on the corner post 33 of the second frame 20. The guide rail 34 provides a predetermined movement trajectory for the sliding of the connecting component 60, ensuring that the connecting component 60 can move along a fixed path during the unfolding or retraction of the box.

[0036] The connecting assembly 60 includes a slider 61 that mates with the guide rail 34 and a connecting rod assembly hinged to the slider 61. The slider 61 slides along the guide rail 34 and can reciprocate along the extension direction of the guide rail 34. One end of the connecting rod assembly is hinged to the slider 61, and the other end is connected to the other end of the folding beam 50. In this way, the other end of the folding beam 50 is connected to the slider 61 via the connecting rod assembly, thereby forming a movable connection between the slider 61 and the second frame 20.

[0037] When the box is in the folded-down state, the first frame 10 and the second frame 20 are close to each other, and the folding beam 50 is folded between the two frames. At this time, the slider 61 is located in the middle of the guide rail 34. When the box needs to be unfolded, the operator lifts the second frame 20 relative to the first frame 10. During this process, the second frame 20 moves away from the first frame 10. Since one end of the folding beam 50 is hinged to the first frame 10, the folding beam 50 begins to rotate relative to the first frame 10. At the same time, the slider 61 slides along the guide rail 34 towards its end under the drive of the connecting rod assembly to adapt to the change in the position of its other end relative to the second frame 20 during the rotation of the folding beam 50. The guiding effect of the guide rail 34 on the slider 61 ensures the smooth and reliable movement of the connecting assembly 60 and avoids the folding beam 50 from tilting or getting stuck during unfolding.

[0038] As an intermediate component connecting the slider 61 and the folding beam 50, the connecting rod assembly can adapt to changes in the angle and relative distance between the two as the folding beam 50 rotates relative to the second frame 20. Through the sliding of the slider 61 along the guide rail 34 and the hinged movement of the connecting rod assembly, the connecting assembly 60 can drive the folding beam 50 to rotate relative to the first frame 10 to a preset angle when the second frame 20 moves away from the first frame 10, thus completing the first stage of the box unfolding process.

[0039] By setting a guide rail 34 on the second frame 20 and cooperating with the slider 61 and connecting rod assembly, the movement of the second frame 20 relative to the first frame 10 can be smoothly and reliably converted into the rotation of the folding beam 50. The guide rail 34 provides a clear trajectory constraint for the slider 61, ensuring the stability and controllability of the movement of the folding beam 50 during unfolding, avoiding swaying or jamming of the folding beam 50 during unfolding, and improving the smoothness and consistency of the box unfolding and folding process.

[0040] In one embodiment, the connecting rod assembly includes a first rod 63 hinged to the slider 61 and a second rod 64 hinged to the other end of the folding beam 50; the first rod 63 has a first guide groove 651 along its length direction, and the second rod 64 has a second guide groove 652 along its length direction; a sliding shaft 66 is movably inserted between the first guide groove 651 and the second guide groove 652.

[0041] In this embodiment, the connecting rod assembly includes a first rod 63 and a second rod 64. One end of the first rod 63 is hinged to the slider 61, and one end of the second rod 64 is hinged to the other end of the folding beam 50. The first rod 63 and the second rod 64 are movably connected through the cooperation of the first guide groove 651, the second guide groove 652, and the sliding shaft 66.

[0042] Specifically, the first rod 63 has a first guide groove 651 along its length, which is an elongated slot extending along the length of the first rod 63. The second rod 64 has a second guide groove 652 along its length, which is also an elongated slot extending along the length of the second rod 64. A sliding shaft 66 is movably inserted into the first guide groove 651 and the second guide groove 652, with the axis of the sliding shaft 66 perpendicular to the length direction of the first rod 63 and the second rod 64. Through the double sliding engagement of the sliding shaft 66 with the first guide groove 651 and the second guide groove 652, the first rod 63 and the second rod 64 can both rotate relative to each other and slide relative to each other along the extension direction of their respective guide grooves, thus providing greater freedom of movement.

[0043] This structure, where the first rod 63 and the second rod 64 are connected via the first guide groove 651, the second guide groove 652, and the sliding shaft 66, is designed to accommodate changes in the angle and distance of the folding beam 50 relative to the second frame 20 as the beam rotates. During the unfolding of the box, the folding beam 50 rotates around its hinge point with the first frame 10, and the other end of the folding beam 50 experiences both angular and distance changes relative to the second frame 20. Since the first rod 63 is hinged to the slider 61 and the second rod 64 is hinged to the other end of the folding beam 50, the relative angle between the first rod 63 and the second rod 64 changes as the beam 50 rotates, and the effective connection length between them also needs to be adjusted accordingly. At this time, the sliding shaft 66 slides within the first guide groove 651 and the second guide groove 652 respectively, which can simultaneously compensate for changes in the effective length and angle between the first rod 63 and the second rod 64, providing better motion adaptability compared to a single guide groove structure. This structural design is simple and reliable, and the movement process is smooth and stable. It avoids movement interference or jamming caused by rigid connections, and ensures the reliability of the box's unfolding and retracting actions.

[0044] In one embodiment, the first rod 63 includes two opposing side walls and a bottom wall connecting the two side walls; the first guide groove 651 is respectively formed on the two side walls of the first rod 63 and extends along the length direction of the first rod 63; the second rod 64 is movably inserted between the two side walls of the first rod 63; the two ends of the sliding shaft 66 are respectively inserted into the first guide groove 651 on the two side walls of the first rod 63, and the middle part of the sliding shaft 66 is inserted into the second guide groove 652 of the second rod 64.

[0045] In this embodiment, the first rod 63 includes two opposing sidewalls and a bottom wall connecting the two sidewalls. The two sidewalls are parallel to each other and spaced apart, and the bottom wall is connected to the same end of the two sidewalls, thereby forming a U-shaped groove structure. This structure gives the first rod 63 sufficient structural strength, while creating a space between the two sidewalls to accommodate the second rod 64. Here, the U-shaped opening faces the slider, that is, the end of the U-shaped opening is rotatably connected to the slider.

[0046] First guide grooves 651 are respectively formed on the two side walls of the first rod 63. The first guide grooves 651 on the two side walls are arranged opposite each other and both extend along the length direction of the first rod 63. The first guide grooves 651 on the two side walls are corresponding to each other in position to ensure that the sliding shaft 66 can pass through the first guide grooves 651 on both sides at the same time and maintain movement. The length of the first guide groove 651 is determined according to the sliding stroke required by the sliding shaft 66 during the unfolding and retraction of the folding beam 50, so as to ensure that the connecting rod assembly has sufficient adjustment margin during the entire movement.

[0047] The second member 64 is movably inserted between the two side walls of the first member 63. The second member 64 is located within the groove of the first member 63, and its width is smaller than the distance between the two side walls, allowing the second member 64 to move freely between them. The second member 64 has a second guide groove 652 along its length, and the extension direction of the second guide groove 652 is consistent with the length direction of the second member 64. This insertion method allows the first member 63 to provide a lateral constraint on the second member 64, limiting the lateral displacement of the second member 64 relative to the first member 63 and ensuring the stability of their movement.

[0048] The axis of the sliding shaft 66 extends along the spacing of the two side walls of the first rod 63, perpendicular to the length direction of the first rod 63 and the second rod 64. Both ends of the sliding shaft 66 pass through the first guide grooves 651 on the two side walls of the first rod 63, and the middle part of the sliding shaft 66 passes through the second guide groove 652 of the second rod 64. The simultaneous engagement of both ends of the sliding shaft 66 with the first guide grooves 651 on the side walls makes the sliding of the sliding shaft 66 within the first guide grooves 651 smoother, avoiding tilting or jamming caused by unilateral force. Simultaneously, the middle part of the sliding shaft 66 engages with the second guide groove 652 on the second rod 64, allowing the sliding shaft 66 to slide relative to the second rod 64 along the extension direction of the second guide groove 652.

[0049] During the unfolding or folding of the box, when the folding beam 50 changes angle and distance relative to the second frame 20, the second rod 64 moves with the folding beam 50. Simultaneously, both ends of the sliding shaft 66 slide synchronously within the first guide grooves 651 on both side walls, while the middle of the sliding shaft 66 slides within the second guide groove 652 of the second rod 64. Because the sliding shaft 66 is simultaneously constrained and guided by both the first and second guide grooves 651 and 652, a wider range of relative displacement adjustment can be achieved between the first rod 63 and the second rod 64. Their movement trajectory is precisely defined, ensuring smooth and reliable relative movement between the first rod 63 and the second rod 64. Furthermore, the structure of the second rod 64 passing between the side walls of the first rod 63 ensures that the second rod 64 remains within the groove of the first rod 63 during movement, preventing the second rod 64 from detaching from the first rod 63 or experiencing lateral displacement.

[0050] By designing the first rod 63 as a U-shaped structure and creating first guide grooves 651 on both side walls, while simultaneously creating a second guide groove 652 on the second rod 64, the sliding shaft 66 can be subjected to dual guiding constraints, improving the stability and reliability of the connecting rod assembly's movement and increasing the range of motion adjustment. This structural design makes the fit between the first rod 63 and the second rod 64 more compact, the force transmission path more rational, and effectively improves the overall structural strength and service life of the connecting assembly 60.

[0051] In one embodiment, the other end of the folding beam 50 is provided with a positioning groove 53, and one end of the second rod 64 is hinged to the side wall of the positioning groove 53; the two ends of the guide rail 34 extend to the top beam 31 and bottom beam 32 adjacent to the second frame 20, respectively; the connecting rod assembly is configured such that when the folding beam 50 is perpendicular to the first frame 10 and the second frame 20, the first rod 63 is located on the corresponding side of the second frame 20, so that the first rod 63 can be vertically inserted into the positioning groove 53 and limit the positioning groove 53.

[0052] In this embodiment, a positioning groove 53 is provided at the other end of the folding beam 50. The positioning groove 53 is formed by a recess inward from the end of the folding beam 50. The opening of the positioning groove 53 faces the second frame 20, and the extension direction of the groove cavity is consistent with the length direction of the folding beam 50. The width of the positioning groove 53 is adapted to the width of the first rod 63, so that the first rod 63 can be inserted into the positioning groove 53.

[0053] One end of the second rod 64 is hinged to the side wall of the positioning groove 53. Specifically, the hinged end of the second rod 64 is rotatably connected to the side wall of the positioning groove 53 via a hinge axis, the axis of which is perpendicular to the length direction of the folding beam 50. By hinged to the side wall of the positioning groove 53, the second rod 64 can rotate relative to the folding beam 50 around the hinge axis to accommodate changes in the angle between the connecting rod assembly and the folding beam 50 during the unfolding and folding of the box. Simultaneously, this hinged connection allows the second rod 64 to be positioned on one side of the positioning groove 53, reserving space for the first rod 63 to be inserted into the positioning groove 53.

[0054] The guide rail 34 extends along the height direction of the second frame 20, with its two ends extending to the top beam 31 and bottom beam 32 adjacent to the second frame 20, respectively. That is, the guide rail 34 is arranged along the corner posts 33 of the second frame 20, with its upper end extending near the top beam 31 and its lower end extending near the bottom beam 32, but the overall length of the guide rail 34 does not exceed the outer contour dimension of the second frame 20 in the height direction. This arrangement allows the slider 61 to slide within the entire range of the guide rail 34, fully utilizing the space of the second frame 20 in the height direction while ensuring the compactness of the overall box structure.

[0055] The connecting rod assembly is configured such that when the folding beam 50 is perpendicular to the first frame 10 and the second frame 20, the first rod 63 is located on the corresponding side of the second frame 20. Specifically, when the box is fully unfolded and the folding beam 50 rotates to a position perpendicular to both the first frame 10 and the second frame 20, the slider 61 slides along the guide rail 34 to a position adjacent to the top beam 31 or the bottom beam 32, causing the first rod 63 to move to the corresponding side of the second frame 20. For the upper folding beam, the slider 61 slides to the upper end of the guide rail 34 adjacent to the top beam 31, and the first rod 63 is located on the side of the top beam 31 of the second frame 20; for the lower folding beam, the slider 61 slides to the lower end of the guide rail 34 adjacent to the bottom beam 32, and the first rod 63 is located on the side of the bottom beam 32 of the second frame 20. At this time, since the folding beam 50 is in a horizontal state and perpendicular to the second frame 20, the first rod 63 is in a vertical position, and the position of the first rod 63 is exactly aligned with the opening of the positioning groove 53 at the other end of the folding beam 50.

[0056] In this state, the first rod 63 can be vertically inserted into the positioning groove 53 and engaged with it. After the first rod 63 is inserted into the positioning groove 53, the sidewall of the positioning groove 53 provides a lateral constraint on the first rod 63, limiting its lateral movement relative to the folding beam 50. This engagement locks the other end of the folding beam 50 in the unfolded position, preventing it from swaying in the unfolded state. The engagement of the first rod 63 with the positioning groove 53 effectively creates a rigid support point between the folding beam 50 and the second frame 20, improving the overall structural stability of the box in the unfolded state.

[0057] During the folding process of the box, when the folding beam 50 begins to rotate relative to the first frame 10, the slider 61 slides along the guide rail 34 toward the middle of the second frame 20, and the first rod 63 then exits from the positioning groove 53, releasing the limiting engagement with the positioning groove 53, so that the folding beam 50 can smoothly perform the folding action.

[0058] By creating a positioning groove 53 at the other end of the folding beam 50 and extending the guide rail 34 to the opposite sides of the second frame 20, the first rod 63 can be inserted into the positioning groove 53 to form a limiting fit when the box is fully unfolded. This structural design provides a reliable locking function in the unfolded state of the box, effectively preventing the folding beam 50 from shifting or loosening during use, and enhancing the structural rigidity and safety of the box after it is unfolded.

[0059] In one embodiment, the deployment drive assembly 70 is a lockable gas spring; one end of the deployment drive assembly 70 is hinged to the first frame 10 via a first hinge seat 72, and the first hinge seat 72 is located at the connection between the corner post 33 and the top beam 31 or the bottom beam 32 of the first frame 10; the other end of the deployment drive assembly 70 is hinged to the side wall of the folding beam 50 via a second hinge seat 73, and the distance between the first hinge seat 72 and the second hinge seat 73 is greater than half the length of the folding beam 50.

[0060] In this embodiment, the deployment drive assembly 70 is a lockable gas spring. A lockable gas spring is an elastic element powered by high-pressure gas, which is filled with high-pressure inert gas and provides elastic thrust or tension through the compression and expansion of the gas.

[0061] One end of the unfolding drive assembly 70 is hinged to the first frame 10 via a first hinge seat 72. The first hinge seat 72 is a hinged connector fixedly mounted on the first frame 10, and has a hinge hole for hinged connection with one end of a lockable gas spring. The first hinge seat 72 is located at the connection between the corner post 33 and the top beam 31 or the bottom beam 32 of the first frame 10. Specifically, for the unfolding drive assembly 70 that drives the upper folding beam 50, its first hinge seat 72 is located at the connection between the corner post 33 and the top beam 31; for the unfolding drive assembly 70 that drives the lower folding beam 50, its first hinge seat 72 is located at the connection between the corner post 33 and the bottom beam 32.

[0062] The other end of the unfolding drive assembly 70 is hinged to the side wall of the folding beam 50 via a second hinge seat 73. The second hinge seat 73 is fixedly installed on the side wall of the folding beam 50 and also has a hinge hole for hinged connection with the other end of the lockable gas spring. Through the arrangement of the first hinge seat 72 and the second hinge seat 73, the two ends of the lockable gas spring are respectively hinged to the first frame 10 and the folding beam 50, so that the lockable gas spring can change its tilt angle as the folding beam 50 rotates, and at the same time transmit the driving force generated by its extension and contraction to the folding beam 50.

[0063] The distance between the first hinge seat 72 and the second hinge seat 73 is greater than half the length of the folding beam 50. In other words, the installation position of the second hinge seat 73 on the folding beam 50 is more than half the total length of the folding beam 50 from the hinge point between the folding beam 50 and the first frame 10. This arrangement results in a longer lever arm for the deployment drive assembly 70, enabling it to generate a larger driving torque with a smaller driving force, thus improving driving efficiency. Simultaneously, because the second hinge seat 73 is located slightly outward from the middle of the folding beam 50 along its length, the angle between the deployment drive assembly 70 and the folding beam 50 changes more rationally during rotation, which helps the lockable gas spring maintain a good driving posture and driving efficiency throughout the entire deployment stroke.

[0064] During the unfolding of the housing, once the folding beam 50 rotates to a preset angle via the connecting assembly 60, the lockable gas spring begins to function. At this point, the lockable gas spring is released, and the high-pressure gas inside pushes the piston rod out, applying a thrust to the folding beam 50 through the second hinge seat 73, driving the folding beam 50 to continue rotating relative to the first frame 10. As the lockable gas spring continues to extend, the folding beam 50 gradually rotates to a position perpendicular to both the first frame 10 and the second frame 20.

[0065] By employing a lockable gas spring as the deployment drive assembly 70, with one end hinged to the connection between the corner post 33 of the first frame 10 and the top beam 31 or bottom beam 32, and the other end hinged to an appropriate position on the side wall of the folding beam 50, the deployment drive assembly 70 can provide a smooth and reliable auxiliary driving force for the deployment of the folding beam 50. This structural design simplifies the deployment operation process of the box and improves the safety and controllability of the deployment process.

[0066] In other embodiments, the deployment drive assembly 70 may also be a linear telescopic mechanism such as a hydraulic rod.

[0067] In one embodiment, the multiple folding beams 50 include two upper folding beams and two lower folding beams; a prefabricated roof template 80 is disposed between the two upper folding beams, and a prefabricated base template 90 is disposed between the two lower folding beams; the unfolding drive assembly 70 is disposed on one side of each upper folding beam and each lower folding beam.

[0068] In this embodiment, the multiple folding beams 50 include two upper folding beams and two lower folding beams. The two upper folding beams are located at the upper part of the box body, connecting the top areas of the first frame 10 and the second frame 20, and supporting the roof structure of the box body. The two lower folding beams are located at the lower part of the box body, connecting the bottom areas of the first frame 10 and the second frame 20, and supporting the bottom plate structure of the box body. The two upper folding beams are parallel to each other and spaced apart, and the two lower folding beams are also parallel to each other and spaced apart. Both the upper and lower folding beams extend along the depth direction of the box body, that is, along the direction from the first frame 10 to the second frame 20.

[0069] A prefabricated roof formwork 80 is installed between the two upper folding beams. The prefabricated roof formwork 80 is a pre-fabricated panel component manufactured in a factory, with its two edges fixedly connected to the two upper folding beams. The prefabricated roof formwork 80 and the two upper folding beams together form the roof structure of the box-shaped structure, providing shelter from rain and sunlight and enclosing the space. The prefabricated roof formwork 80 can be made of metal composite panels, color steel sandwich panels, or other suitable building materials, possessing good waterproof and thermal insulation properties. In the folded state of the box-shaped structure, the prefabricated roof formwork 80 folds and retracts along with the two upper folding beams; in the unfolded state of the box-shaped structure, the prefabricated roof formwork 80 unfolds to a horizontal position along with the two upper folding beams, forming a complete roof plane.

[0070] A prefabricated base plate template 90 is installed between the two lower folding beams. The prefabricated base plate template 90 is also a pre-fabricated plate-shaped component manufactured in the factory, with its two edges fixedly connected to the two lower folding beams. The prefabricated base plate template 90 and the two lower folding beams together form the base plate structure of the box-like structure, used to support personnel movement and the placement of goods, providing bottom support for the space. The prefabricated base plate template 90 can be made of sheet material with sufficient load-bearing capacity, and its surface can be treated with an anti-slip finish to ensure walking safety. In the folded state of the box-like structure, the prefabricated base plate template 90 folds and retracts along with the two lower folding beams; in the unfolded state of the box-like structure, the prefabricated base plate template 90 unfolds to a horizontal position along with the two lower folding beams, forming a flat ground surface.

[0071] Each upper folding beam and each lower folding beam is equipped with an unfolding drive assembly 70 on one side. That is, each of the two upper folding beams has one unfolding drive assembly 70, and each of the two lower folding beams also has one unfolding drive assembly 70, for a total of four unfolding drive assemblies 70 in the housing. The two ends of each unfolding drive assembly 70 are hinged to the first frame 10 and the corresponding folding beam 50, respectively, and are used to drive the folding beam 50 to continue rotating to the fully unfolded position after it has rotated to a preset angle. By configuring an unfolding drive assembly 70 for each folding beam 50 individually, each folding beam 50 can obtain independent driving force, ensuring that the upper and lower folding beams can complete the unfolding action synchronously and smoothly. At the same time, the multiple unfolding drive assemblies 70 work together to share the driving load, reducing the load on a single unfolding drive assembly 70 and improving the reliability of the unfolding process.

[0072] During the unfolding of the container, the operator lifts the second frame 20 relative to the first frame 10, and the two upper folding beams and two lower folding beams rotate outward synchronously under the drive of their respective connecting components 60. Once each folding beam 50 has rotated to a preset angle, the four unfolding drive components 70 drive the corresponding folding beam 50 to continue rotating until both the two upper folding beams and two lower folding beams have rotated to a position perpendicular to the first frame 10 and the second frame 20. At this point, the precast roof template 80 and the precast base template 90 unfold to a horizontal state, and the container forms a three-dimensional spatial structure with a complete roof and base.

[0073] By setting up two upper folding beams and two lower folding beams, and installing precast roof templates 80 and precast bottom templates 90 between them, the box-type structure has a complete top and bottom enclosure structure after unfolding, eliminating the need for on-site installation of the roof and floor, further shortening on-site construction time. Simultaneously, each folding beam 50 is equipped with an independent unfolding drive assembly 70, ensuring the synchronicity and stability of the unfolding actions of each folding beam 50, and improving the reliability and safety of the overall box-type structure unfolding process.

[0074] In one embodiment, the functional panel is provided on the inner side of the second frame 20. The functional panel includes a photovoltaic power generation curtain wall module 41, a folding and opening window module 42, and a light-shielding curtain wall module 43. The photovoltaic power generation curtain wall module 41 includes an outer light-transmitting plate, a flexible photovoltaic thin film layer, and an inner light-transmitting plate arranged in sequence.

[0075] In this embodiment, a functional panel is provided on the inner side of the second frame 20. The second frame 20 serves as the end frame of the box away from the main building, and its inner facade constitutes the exterior facade of the space. By placing the functional panel on the inner side of the second frame 20, the exterior facade of the box has multiple functions such as lighting, ventilation, and power generation. At the same time, one side of the first frame 10 can serve as an interface for connection with the main building, facilitating the docking and installation between the box and the main building.

[0076] The functional panels include a photovoltaic power generation curtain wall module 41, a folding and opening window module 42, and a light-shielding curtain wall module 43. These three functional modules are installed on the inner side of the second frame 20 according to a specific layout, based on the usage requirements of the enclosure and the facade design requirements. The photovoltaic power generation curtain wall module 41 converts solar energy into electrical energy to provide power to the electrical equipment inside the enclosure; the folding and opening window module 42 can be opened outwards for natural ventilation; and the light-shielding curtain wall module 43 is used to block sunlight or protect privacy, and can be made of materials with different light transmittance as needed. The three functional modules can be arranged in zones according to the height and width of the facade. For example, the photovoltaic power generation curtain wall module 41 can be placed in the upper area of ​​the facade to obtain more sunlight, the folding and opening window module 42 can be placed in the middle area of ​​the facade for easy opening, and the light-shielding curtain wall module 43 can be placed in the lower area of ​​the facade to provide visual obstruction.

[0077] The photovoltaic power generation curtain wall module 41 includes an outer light-transmitting panel, a flexible photovoltaic thin film layer, and an inner light-transmitting panel arranged in sequence. The outer light-transmitting panel is located on the outermost side of the photovoltaic power generation curtain wall module 41, directly facing the outdoor environment, and is used to protect the inner flexible photovoltaic thin film layer from wind and rain erosion and external impact.

[0078] The flexible photovoltaic thin film layer, located between the outer and inner light-transmitting panels, is the power generation component of the photovoltaic power generation curtain wall module 41. Under sunlight, the flexible photovoltaic thin film layer generates a photovoltaic effect, converting solar energy into direct current (DC) electricity. Simultaneously, the flexible photovoltaic thin film layer has a certain degree of light transmittance, allowing some natural light to pass through while generating electricity, thus providing lighting for the space.

[0079] The inner light-transmitting panel is located on the innermost side of the photovoltaic power generation curtain wall module 41, facing the interior space. The outer light-transmitting panel, the flexible photovoltaic film layer, and the inner light-transmitting panel are stacked in sequence and bonded together by adhesive bonding or mechanical fixing to form a composite curtain wall panel with photovoltaic power generation function.

[0080] By integrating the photovoltaic power generation curtain wall module 41, the folding and opening window module 42, and the shading curtain wall module 43 into the inner side of the second frame 20, the exterior facade of the enclosure simultaneously possesses multiple functions such as power generation, ventilation, and shading, meeting the building's dual requirements for energy conservation, environmental protection, and comfortable use. The photovoltaic power generation curtain wall module 41 adopts a sandwich structure with an outer light-transmitting panel, a flexible photovoltaic thin film layer, and an inner light-transmitting panel distributed in sequence. This ensures both the power generation efficiency and lifespan of the photovoltaic modules and takes into account the light transmittance of the curtain wall, achieving the integration of building functions and photovoltaic power generation.

[0081] In one embodiment, the system further includes a photovoltaic-storage-lighting electrical system 100; the photovoltaic-storage-lighting electrical system 100 includes an MPPT voltage regulator module 101, an energy storage battery unit 102, a DC bus 103, and a lighting module 104; the photovoltaic power generation curtain wall module 41 is electrically connected to the MPPT voltage regulator module 101 through a pre-embedded line 105, the output terminal of the MPPT voltage regulator module 101 is connected to the DC bus 103, and the DC bus 103 is electrically connected to the energy storage battery unit 102 and the lighting module 104 respectively.

[0082] In this embodiment, the photovoltaic energy storage driven foldable modular enclosure also includes a photovoltaic energy storage lighting electrical system 100. The photovoltaic energy storage lighting electrical system 100 is used to manage, store, and utilize the electrical energy generated by the photovoltaic power generation curtain wall module 41, achieving self-sufficiency in enclosure lighting. The photovoltaic energy storage lighting electrical system 100 includes an MPPT voltage regulator module 101, an energy storage battery unit 102, a DC bus 103, and a lighting module 104.

[0083] The photovoltaic power generation curtain wall module 41 is electrically connected to the MPPT voltage regulator module 101 via a pre-embedded wiring 105. The pre-embedded wiring 105 is pre-laid inside the second frame 20 to transmit the DC power generated by the photovoltaic power generation curtain wall module 41 to the MPPT voltage regulator module 101. The MPPT voltage regulator module 101 is a maximum power point tracking controller, which can track the maximum power output point of the photovoltaic power generation curtain wall module 41 in real time, so that the photovoltaic module always works in the optimal power generation state, while converting the input voltage into a stable DC output voltage.

[0084] The output of the MPPT voltage regulator module 101 is connected to the DC bus 103. The DC bus 103 serves as the power collection and distribution channel for the photovoltaic-storage-lighting electrical system 100, transmitting the power output from the MPPT voltage regulator module 101 to each power-consuming unit. The DC bus 103 is electrically connected to the energy storage battery unit 102 and the lighting module 104. The energy storage battery unit 102 stores excess power generated by the photovoltaic power generation curtain wall module 41 and releases power to the DC bus 103 when there is insufficient sunlight or at night, ensuring continuous power supply to the lighting module 104. The lighting module 104 obtains power from the DC bus 103 to provide lighting for the space.

[0085] By setting up a photovoltaic, energy storage, lighting, and electrical system 100, photovoltaic power generation, energy storage, and lighting functions are integrated into the enclosure, giving the enclosure an independent power supply capability.

[0086] In one embodiment, the light storage lighting electrical system 100 further includes a power line carrier communication module 106 coupled to the DC bus 103; the power line carrier communication module 106 is configured to modulate and load control signals onto the DC bus 103, and the lighting module 104 has a demodulation module 107 for receiving the control signals from the DC bus 103 to adjust the switching state or brightness.

[0087] In this embodiment, the photovoltaic energy storage lighting electrical system 100 also includes a power line carrier communication module 106. The power line carrier communication module 106 is coupled to the DC bus 103, using the DC bus 103 as the transmission medium for communication signals, eliminating the need to lay dedicated communication cables separately.

[0088] The power line carrier communication module 106 is configured to modulate and load control signals onto the DC bus 103. Specifically, the power line carrier communication module 106 modulates control commands into high-frequency signals, which are then superimposed on the DC voltage of the DC bus 103 for transmission. This control signal shares the same transmission line as the power supply to the DC bus 103, thus achieving the integration of power transmission and signal transmission.

[0089] The lighting module 104 includes a demodulation module 107. The demodulation module 107 receives control signals from the DC bus 103 and demodulates and restores these signals. The lighting module 104 adjusts its on / off state or brightness according to the demodulated control signal. By sending different control signals through the power line carrier communication module 106, remote on / off and brightness adjustment functions of the lighting module 104 can be achieved.

[0090] By adopting power line carrier communication technology, the DC bus 103 can simultaneously carry power transmission and signal transmission functions, simplifying the wiring inside the enclosure, reducing wiring complexity, and enabling flexible control of the lighting module 104.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
