Description

Technical Field

[0001] This invention relates to the field of mobile hospital technology, specifically to the structure and method of doubling and rapidly deploying mobile hospital operating space, and to a mobile hospital system. Background Technology

[0002] With the increasing frequency of natural disasters, public health emergencies, and the growing complexity of regional security situations worldwide, rapid and efficient medical support capabilities have become a key indicator for measuring a nation's emergency management system and defense mobilization capabilities. Mobile hospitals, also known as makeshift hospitals, are widely used for emergency medical support due to their mobility, modularity, and environmental adaptability. However, existing mainstream makeshift hospitals still suffer from the following core challenges: 1. Direct Container Conversion: This method uses a large number of standard 20-foot containers (approximately 14 square meters of internal space) for conversion. The structure is simple, but the operating space per container is small. Setting up a complete system requires a large number of containers, resulting in a large storage area during normal operation and the need to deploy a large fleet of transport vehicles when needed, leading to high costs and slow response times.

[0003] 2. Single-vehicle single-compartment extended type: This type uses a dedicated vehicle chassis with a single expandable compartment. Although it improves the space of a single module, each vehicle can only carry one functional module, resulting in high investment costs and difficulty in utilizing the connecting space between compartments.

[0004] 3. Land-based expandable modular container type: Although it saves vehicle costs, it still follows the "one vehicle, one container" transportation model, and the transportation efficiency has not been fundamentally improved. The problem of space utilization between containers still exists.

[0005] 4. Lack of system design and difficulty in space utilization: The diversity of existing modular cabin structures and dimensions makes it difficult to accurately control the placement distance between cabins during on-site deployment, resulting in the inability to efficiently and reliably build and utilize the space between adjacent cabins.

[0006] Therefore, two major technical problems urgently need to be solved: first, to significantly increase the effective working space that can be provided by a single transport; and second, to quickly and reliably build and utilize the auxiliary working space between adjacent modular units when it is difficult to maintain consistent spacing between them during on-site deployment. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a structure and method for doubling and rapidly deploying the working space of a modular mobile hospital, as well as a mobile hospital system. Through the design of narrow-body modular units and an adaptive canopy connection system, the effective working space can be significantly increased under the same transport volume. Furthermore, it can quickly and reliably build auxiliary working spaces between adjacent modular units when there are errors in on-site deployment, thereby comprehensively improving the emergency response capability and on-site operating conditions of the mobile hospital system.

[0008] To achieve the above objectives, a structure for doubling and rapidly deploying the working space of a modular mobile hospital is designed, including at least two expandable double-wing modular units and a canopy system. Each expandable double-wing modular unit has a top panel, floor, side panels, and end panels that can be unfolded to form an expanded space. In the canopy system, the top joints on both sides are connected to the near-center ends of support rods, and the distal ends of the support rods are connected to side joints, together forming an A-frame support frame. A connecting horizontal tube is provided between two adjacent top joints. The top panel of the expandable modular unit is provided with multiple first and second connecting seats. The top and side joints of the A-frame support frame of the canopy system are adjustable in angle, and the side joints are provided with connectors that can be detachably connected to the first connecting seats. The two expandable double-wing modular units are arranged side-by-side, connected to the first connecting seats on the top panels of the two modular units via the connectors of the side joints. The connecting seats are used to erect the canopy system on top of the two structures, and after covering it with a tarpaulin, a basic expansion unit is formed. Four double-wing expandable cabins are arranged in two rows and two columns, forming a central area. Two retractable connecting tubes are arranged parallel to each other above the central area, forming the overall frame. The length of each retractable connecting tube is adjustable, and each end has a second connector, which is detachably connected to a second connecting seat on the top plate of the double-wing expandable cabin via the second connector. Several third connecting seats are provided on the body of each retractable connecting tube. Several side joint connectors on the canopy system are detachably connected to a first connecting seat on the edge of the top plate of the double-wing expandable cabin and to the third connecting seats on the retractable connecting tubes, respectively, achieving full coverage of the area above the four double-wing expandable cabins. This allows for covering with a tarpaulin or, after covering with a tarpaulin, installing a curtain to form a combined expansion unit.

[0009] Preferably, the present invention further includes: a cross support rod assembly is provided between two adjacent "A"-shaped support frames, the cross support rod assembly being hinged to the support rod, and forming an integrated unfolding or folding storage structure with the adjacent "A"-shaped support frames.

[0010] Preferably, the present invention further includes: the length of the support rod adopts a redundant design, that is, when the "A"-shaped support frame is fully extended to the set minimum drainage slope angle, the maximum total width between the connecting parts at both ends is greater than the deviation distance between adjacent cabins.

[0011] Preferably, the present invention further includes: the double-wing expandable container is a narrow-body container, the width of which in its non-expanded state is no greater than 1 / 2 of the width of a standard 20-foot container, and two or four of the narrow-body containers are arranged side by side on a 20-foot or 40-foot flatbed trailer for centralized transportation in the stowed state.

[0012] Preferably, the present invention further includes: in the non-expanded state of the narrow-body cabin, a medical equipment integration and arrangement area with a width of not less than 800mm is arranged longitudinally between the internal side panels.

[0013] Preferably, the present invention further includes: one end face of the narrow-body container is provided with an air conditioning unit, an operation panel, a power interface, an information interface, a sewage pipe connection port, a clean water pipe connection port, and a spare ladder from top to bottom; and door openings are provided on the other end face and the two side panels.

[0014] Preferably, the present invention further includes: a solar cell assembly is provided on the top of the main body of the modular cabin.

[0015] Preferably, the present invention further includes: the bottom of the narrow-body container is provided with casters that can be raised and lowered; and the bottom frames on both sides of the narrow-body container are provided with support arms that can be extended 90 degrees.

[0016] Preferably, the present invention further includes: a water channel is provided on the outer edge of the top plate of the container for receiving and diverting rainwater flowing down from the top of the container and the surface of the tarpaulin, wherein the water channel is an integral channel formed by directly stretching and forming an aluminum profile on the outer frame of the top plate of the container; or it is formed by extending the outer edge of the tarpaulin downward to below the edge of the top plate of the container and then flipping it upward and fixing it.

[0017] Preferably, the present invention further includes: the connecting parts of the side joint and the second connecting parts at both ends of the telescopic connecting tube between the cabins adopt an insertion rod plus fixing part anti-detachment structure, or adopt a screw screwing structure; correspondingly, the first connecting seat, the second connecting seat and the third connecting seat adopt a plug hole structure or nut structure that matches the connecting parts.

[0018] This invention also provides a method for doubling and rapidly deploying the working space of a modular mobile hospital. Based on the aforementioned structure, the method includes the following steps: Step 1, transporting the expandable modular hospital to the target camp and arranging the modular hospitals in two rows and two columns according to their functions; Step 2, above the central area where four modular hospitals are grouped together, a frame is formed by detachably connecting the second connectors at both ends of two parallel telescopic connecting pipes between the modular hospitals to the second connecting seats at the corners of the roof panels of the four modular hospitals; Step 3, stretching and unfolding multiple A-frame support frames, connecting them to the first connecting seats at the edge of the roof panel and the third connecting seats on the telescopic connecting pipes between the modular hospitals through connectors at the bottom of their side joints, achieving full coverage of the area above the four modular hospitals, and combining them with a tarpaulin to form a complete combined expansion unit; Step 4, integrating and arranging several combined expansion units to form a modular mobile hospital system.

[0019] The present invention also provides a modular mobile hospital system, the system comprising at least one basic expansion unit formed by the aforementioned structure and / or at least one combined expansion unit formed by the aforementioned structure, and configured with corresponding functional modules according to the needs of the rescue mission, forming mobile hospital systems of different scales and treatment capabilities.

[0020] Compared with the prior art, the advantages of this invention are: 1. Modular Space Expansion Mode: It adopts a two-level modular structure of "basic expansion unit" and "combined expansion unit". It can be quickly connected to the pre-installed multi-point connecting seat on the top plate of the container and the angle-adjustable "V"-shaped support frame to realize the closed utilization of space between adjacent containers.

[0021] 2. Overcoming the contradiction between "rapid deployment" and "positioning error": Rapid on-site deployment requires a simplified setup process, but the placement of modular units inevitably involves positioning errors. This invention creatively employs a technical approach of "replacing precise alignment with adaptive adjustment," designing adjustable-angle tent frame joints, redundant support rods, and retractable connecting pipes. This allows the system to adapt to changes in spacing, enabling rapid deployment without precise alignment.

[0022] 3. Creative Breakthrough in Resolving the Contradiction Between "Transportation Efficiency" and "Operating Space": The conventional approach is to increase the number of vehicles or enlarge the size of individual vehicles. This invention takes a different approach, achieving a qualitative leap in transportation efficiency through a technical route of "narrow-body design + multi-compartment parallel transport + space combination." The combined expansion unit, consisting of four narrow-body containers, requires only one 40-foot flatbed trailer for transport, providing approximately 220 square meters of operating space (120 square meters of container expansion area and approximately 100 square meters of auxiliary space), which is more than 650% higher than the traditional container solution (approximately 28 square meters) and more than 175% higher than the single-vehicle, single-compartment solution (approximately 80 square meters).

[0023] 4. Collaborative innovation in structural design: The triangular stability of the "A"-shaped support frame, the wind resistance of the cross support rods, the drainage function of the water channel, the anti-tipping function of the support arm, the fine adjustment function of the casters, and the solar energy storage system are organically combined to form a complete technical solution. The various features support each other and work together to maintain structural stability and safety under extreme weather conditions and ensure power supply for important rescue operations.

[0024] 5. System integration flexibility: Through the modular combination of basic expansion units and combined expansion units, this system integration method can quickly build mobile hospitals of various sizes, ranging from tens of square meters to thousands of square meters, to meet the differentiated needs of different disaster scenarios.

Detailed Implementation

[0042] To make the purpose, principle and structure of the present invention clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0043] See Figures 1 to 16 The mobile hospital structure for increasing and rapidly deploying operational space provided by the present invention includes a two-wing expandable modular unit 100 and a canopy system 200.

[0044] Furthermore, in this specification, the following terms indicating direction, "front," "back," "ahead (front side)," "rear (back side)," "left," "right," "left side," "right side," "up," "down," "above," and "below," as well as any other similar terms indicating direction, are defined as follows. "Front" and "ahead (front side)" indicate proximity. Figure 1 The first direction is the first end face of the expandable container 100 that can be directly observed in the front view. "Rear" and "rear (rear side)" are directions opposite to the first direction, i.e., away from. Figure 1 The orientation of the first end face of the expandable container 100 that is directly observable in the front view. "Forward / backward direction" corresponds to the length direction of the expandable container 100. "Up" and "above" indicate a second direction near the top of the expandable container 100. "Down" and "below" indicate directions opposite to the second direction. "Left," "left side," "right," and "right side" are defined based on "up" and "down."

[0045] like Figure 1 and Figure 2 As shown, the twin-wing expandable container 100 has an upward-flipping top plate 110, side plates 120 and end plates 130, and a floor 140 at its bottom.

[0046] The twin-wing expandable cabin 100 adopts a highly symmetrical structural layout. The top plate 110, side plates 120, end plates 130, and floor 140 are all rotatably connected to the main frame of the twin-wing expandable cabin 100 through a hinge mechanism, forming a twin-wing expansion structure that can be quickly deployed to both sides. The top plate 110 is an integral plate located on the top of the side of the twin-wing expandable cabin 100. Its edge is provided with continuous hinges along the length of the twin-wing expandable cabin 100, and is firmly and rotatably connected to the corresponding edge of the top frame of the twin-wing expandable cabin 100. This allows the top plate 110 to be smoothly flipped upward around the hinge axis to a preset angle, forming a ceiling for the expansion space on both sides of the twin-wing expandable cabin 100. Furthermore, by folding the first connecting seat 111 on the outer periphery of the top plate 110 and the second connecting seats 112 at the four corners to the working surface facing upward, it provides a clear operating surface and a stable support foundation for the subsequent installation of the canopy system 200.

[0047] Floor 140 is one of the core components of the twin-wing structure. It is precisely and symmetrically arranged as two identical independent panels, left and right. The inner long edge of each floor 140 (adjacent to the centerline of the twin-wing expandable container 100) is rigidly connected to the left and right side edges of the bottom frame of the twin-wing expandable container 100 via heavy-duty hinges. The hinge axis is strictly parallel to the longitudinal centerline of the twin-wing expandable container 100 to ensure symmetry during the folding and unfolding process. In the transport state, the left and right floor panels 140 are folded upwards and pressed tightly against the left and right sides of the twin-wing expandable container 100 to maintain the overall compact shape. When unfolding, the operator simultaneously flips the left and right floor panels 140 horizontally to the sides and lowers them. The floor panels 140 rotate around the hinges to a working position parallel to the ground. During this process, the foldable support legs 141, pre-installed at the far end (outer edge) of each floor 140, automatically unfold under gravity or slight manual assistance. Their ends are firmly supported on the ground, forming a multi-point support system together with the bottom support structure of the container body, effectively ensuring the flatness, levelness and load-bearing capacity of the extended floor. The foldable support legs 141 are also connected to the floor 140 by small hinges. When not unfolded, they are completely folded and stored in the grooves on the floor 140 to avoid shaking or damage during transportation.

[0048] The side panels 120 strictly follow the principle of left-right symmetry and are independently set on the left and right sides of the body of the double-wing expandable container 100. The inner edge of each side panel 120 is connected to the corresponding outer edge of the floor 140 through continuous hinges. Furthermore, a folding angle limiting component is connected between the side panel 120 and the floor 140. The folding angle limiting component can be a flexible chain, which is used to limit the angle at which the side panel 120 folds outward relative to the floor 140. In the stowed state, the side panels 120 fit tightly against the inner side of the floor 140 and fold upwards with the floor 140, storing on both sides of the main body of the twin-wing expandable container 100. When unfolded, the left and right side panels 120 simultaneously flip outwards to a working position that is basically perpendicular to the floor 140 in the horizontal state, forming a symmetrical lateral enclosure structure for the expanded space. The upper edge of the side panels 120 naturally connects with the outer edge of the flipped top panel 110, and the lower edge of the side panels 120 is connected to the outer edge of the flipped floor 140 through a hinge, forming a continuous support profile that provides a reliable support for the expansion structure and tarpaulin covering frame of the twin-wing expandable container 100.

[0049] Several end plates 130 are symmetrically arranged at the front and rear ends of the twin-wing expandable container 100. Each end plate 130 is connected to the vertical side edge of the front and rear end frames of the twin-wing expandable container 100 via hinges, and can be opened laterally by flipping. In the folded state, the end plates 130 are stowed close to the two sides of the twin-wing expandable container 100. In the unfolded state, the upper, lower, and outer edges of the end plates 130 can respectively engage with the edges of the top plate 110, the floor 140, and the side plate 120, forming supports between the top plate 110 and the floor 140, and between the floor 120 and the side plate 120. The folding and unfolding action of the two sets of support relationships is fully unfolded to the working position through the rigid support of the end plate 130, forming a stable enclosed structure for the lateral unfolding space of the twin-wing expandable container 100, providing a large enclosed internal cavity within the expandable container 100.

[0050] Through the precise hinge connection and coordinated flipping action of the aforementioned panels and the main body of the expandable double-wing cabin 100, the expandable double-wing cabin 100 naturally forms a completely symmetrical "double-wing" shape after unfolding: the main body of the expandable double-wing cabin 100 serves as the central functional area, the left and right side panels 120 stand upright to form symmetrical side walls, the left and right floor panels 140 extend horizontally to form symmetrical working planes, the top panel 110 flips to provide a top interface platform, and the end panels 130 can be opened as needed to support several panels and optimize space functionality. This symmetrical double-wing structure not only significantly increases the effective usable area, but also ensures the mechanical balance and high stability of the overall configuration after unfolding due to the complete symmetry of the left and right sides in terms of structure, weight, and stress, which can evenly distribute the load of the canopy system 200 and the forces of the external environment. The symmetrical design also greatly simplifies on-site operation, as the left and right wings can be unfolded simultaneously, shortening deployment time and meeting the stringent requirements of rapid response in emergency medical care. The symmetrical deployment characteristics of the twin-wing structure lay a solid foundation for the symmetrical installation of the subsequent canopy system 200 on the insertion holes of the top plate 110 of the twin-wing expandable container 100, further enhancing the overall system's spatial expansion capability and environmental adaptability.

[0051] Multiple first connecting seats 111 are evenly arranged along the outer periphery of the top plate 110, and second connecting seats 112 are arranged at the four corners of the top plate 110. For example... Figure 14 As shown, the bottom four corners of the expandable double-wing container 100 are equipped with liftable casters 170. Each caster 170 consists of an upper telescopic rod and lower rollers, facilitating precise short-distance movement and position adjustment on-site. Simultaneously, support arms 160 that can extend 90 degrees are installed on the two side bottom frames of the expandable double-wing container 100. After the container 100 is transported to the designated location, the support arms 160 are rotated out and placed on the ground, effectively preventing the container from overturning under wind or accidental collisions, ensuring system stability and safety.

[0052] The canopy system 200 is composed of modular components such as the top joint 210, support rod 220, side joint 230, connecting horizontal tube 240, telescopic connecting tube 260, and cross support rod assembly 270.

[0053] The top joint 210 adopts a symmetrical structural design, consisting of two identical molded parts joined by a central hinge shaft. It is a wide-angle structure with an adjustable angle, and the molded parts are the first molded part and the second molded part. The upper outer contour of the molded part is machined into a smooth cylindrical surface, effectively preventing the tarpaulin 300 from being snagged or worn by sharp edges during the covering process. A connecting horizontal tube 240 is inserted through the central axis of the upper end face of the first and second molded parts. The first and second connecting parts are hinged by rotating around the connecting horizontal tube 240 as the hinge axis. The included angle between the two molded parts can be steplessly adjusted within the range of 0° to 360°.

[0054] Preferably, the lower part of the first molded part and the second molded part is a sleeve structure, which is used to be sleeved and fixed to the upper end of the support rod 220 respectively.

[0055] The side joint 230 is also an adjustable wide-angle structure. It has a third molded part with a sleeve structure at the top and a first connecting part 232 at the bottom. The third molded part and the first connecting part 232 are hinged together by a pin. The first connecting part 232 is a cylindrical plug-in connector. The outer diameter of the first connecting part 232 precisely matches the first connecting seat 111 on the roof plate 110 and the third connecting seat 261 on the telescopic connecting pipe 260. The first connecting part 232, inserted into the first connecting seat 111, passes through the first connecting seat 111, and its end extends out of the first connecting seat 111. A through hole is opened at the end of the extended portion of the first connecting part 232. The first fixing part 233 is a pin. The first fixing part 233 is inserted into the through hole at the end of the first connecting part 232, forming a limiting and blocking relationship with the through hole of the first connecting seat 111, achieving anti-detachment locking and preventing the first connecting part 232 from coming off the first connecting seat 111.

[0056] Preferably, see Figure 6The first connecting member 232 at the lower part of the side joint 230 can also be a multi-segment bent foot plate structure. Specifically, the upper part of the first connecting member 232 is hinged to the third molded sleeve structure at the upper part of the side joint 230. The lower part of the first connecting member 232 undergoes a torsional change of direction. The lower part of the first connecting member 232 is vertically perpendicular to the upper part, and the lower part of the first connecting member 232 is a horizontally inclined plate structure. The lower surface of the plate structure is attached to the upper surface of the top plate 110, and the plate structure is also provided with a through hole. The first connecting seat 111 is a threaded countersunk hole provided on the upper surface of the top plate 110. The first fixing member 233 is a bolt. The first fixing member 233 passes through the lower through hole of the first connecting member 232, is threadedly engaged with the first connecting seat 111, and the first connecting member 232 is pressed against the top plate 110 by the nut of the bolt.

[0057] The side of the first connector 232 in the side joint 230 is provided with a through-type binding hole 231, which facilitates the passing of binding straps to fix the edge of the tarpaulin 300 or auxiliary ropes. The two ends of the support rod 220 are respectively connected to the first or second forming part of the top joint 210 sleeve structure and the third forming part of the side joint 230 sleeve structure to form a stable "V"-shaped support frame 250 main structure. The length of the "V"-shaped support frame 250 and the support rod 220 is redundantly designed, and its total length is greater than the distance between adjacent cabins 100. During installation, since the two ends of the "V"-shaped support frame 250 need to be connected with the cabins 100, the top joint 210 and the side joint 230 are used to achieve a certain angle of folding and retraction between adjacent support rods 220, so that the support rods 220 form a certain angle of inclination relative to the horizontal plane. This angle of inclination provides a support frame with a drainage tilt angle for the tarpaulin 300, ensuring that a certain roof drainage slope can still be maintained under the maximum allowable distance between adjacent cabins 100. The connecting horizontal tube 240 is inserted into the pre-drilled mounting holes on the side of the adjacent top joint 210, connecting multiple A-frame supports 250 laterally into an integral frame, significantly improving torsional stiffness and overall stability. The tarpaulin 300 covers the integral frame formed by the multiple A-frame supports 250, and connecting straps are provided at the edges of the tarpaulin 300, which are fixedly connected to the A-frame supports 250 by binding straps threaded through the binding holes 231.

[0058] The four-compartment combined expansion unit 600 consists of four biplane expandable cabins 100 arranged symmetrically in two rows and two columns. The top plates 110 of the four biplane expandable cabins 100 enclose a centrally empty rectangular area. This central area is an open space without cabin coverage, and its size is determined by the distance between the outer edges of adjacent biplane expandable cabins 100. It is the core component of the expanded working space. To construct a stable canopy foundation covering this central area, two retractable connecting pipes 260 are erected parallel to each other above the central area. The telescopic connecting tube 260 is composed of a telescopic tube 262 including an inner tube and an outer tube. The inner tube and the outer tube are nested together to slide and extend relative to each other. The telescopic connecting tube 260 is connected to two second connecting members 263 with the same structure as the first connecting member 232 of the side joint. The second connecting members 263 at both ends of the telescopic connecting tube 260 are precisely inserted into the four pre-set second connecting seats 112 at the four corners of the top plate 110 of the four double-wing expandable cabin 100. The second connecting seat 112 can be a through hole penetrating the top plate 110 and is limited and fixed by the second fixing member 264 set at the end. The second fixing member 264 has the same structure as the first fixing member 233 and is a pin inserted into the countersunk hole at the end of the second connecting member 263 to block and limit the through hole of the second connecting seat 112, preventing the second connecting member 263 from coming out of the second connecting seat 112, thereby forming a closed rectangular support frame above the middle area.

[0059] The retractable connecting tube 260 has multiple third connecting seats 261 evenly distributed axially on its outer wall. These seats are used to insert additional side joints 230 and first connecting pieces 232 in the lateral span direction of the middle area, allowing the support rod 220 to form continuous support points above the middle area. The A-frame support frame 250 can be inserted and fitted onto the retractable connecting tube 260 above the middle area. This structural design allows the retractable connecting tube 260 to adapt to minor spacing deviations caused by uneven ground or positioning errors when the double-wing expandable container 100 is placed, ensuring the reliability of the tent frame installation in the middle area and the geometric stability of the overall structure. After being supported by this frame, the middle area can be installed in conjunction with the first connecting seats 111 at the edge of the double-wing expandable container 100 to form a complete A-frame support frame 250 array, ultimately covering the tarpaulin 300 to form a seamless continuous working space, effectively eliminating the common problems of central collapse or weak support in traditional multi-component splicing.

[0060] The cross support rod assembly 270 consists of two high-strength, lightweight rods connected at the center by a hinge axis to form an X-shaped structure. The rods are preferably made of aerospace-grade aluminum alloy or carbon fiber composite material. Each rod has standardized joints at both ends, allowing for quick hinged connections to pre-set cross support rod seats 251 or cross support rod sliding seats 252 on the support rods 220 of adjacent A-frame support frames 250. In operation, the cross support rod assembly 270 unfolds and connects to two adjacent A-frame support frames 250, forming a spatial truss structure. This significantly enhances the overall resistance to lateral deformation through the principle of triangular stability. Under wind loads, the cross rods alternately bear tensile and compressive stresses, effectively distributing the load and improving the wind resistance of the canopy system 200. When stored, the cross support rod assembly 270 can be folded around the central hinge axis. Figure 11-1 The structure shown has a cross-bracing rod sliding seat 252, which allows the rod end to slide on the support rod 220 with limited sliding to accommodate different spacing; Figure 11-2 Showing the fully folded state, the whole thing is flat; Figure 11 —Three examples demonstrate the basic connection method of the non-sliding seat 252, suitable for standard spacing. Two configurations can be flexibly selected according to the spacing of the site shelter 100, ensuring that the tent frame system 200 maintains structural integrity under various environmental conditions while retaining its core advantage of rapid deployment. Preferably, a cross support rod assembly 270 for a tent frame provided in Chinese Patent Application No. 202211130595.3 can be used.

[0061] The canopy system 200 achieves a rigid connection with the insertion holes of the roof panel of the shelter through the precise cooperation of the above components. The joint angle adjustment and the redundant design of the rods together ensure the adaptive capability to the on-site spacing error. The modular interface allows a single person to complete the erection of a single "A" shaped support frame 250 in a short time, fully meeting the dual requirements of deployment efficiency and structural stability in emergency medical scenarios.

[0062] When two expandable wing-shaped cabins 100 need to be arranged side-by-side to form a passageway or auxiliary space, the operator first uses casters 170 to fine-tune the cabin position, then unfolds the support arm 160 to support it on the ground, and then unfolds the expandable wing-shaped cabin 100. During the unfolding process, the floor 140 is flipped down to both sides, and at the same time, the foldable support legs 141 located at the far end of the floor 140 also unfold. Because the spacing between the expandable panels on both sides is limited after unfolding, the foldable support legs 141 are folded and stored on the wall of the panel when the cabin is in the non-unfolded (transportation) state; when the expandable wing-shaped cabin 100 is placed on the ground and the floor 140 begins to unfold, the foldable support legs 141 rotate and fall down, and finally their ends support the ground, providing stable far-end support for the expanded floor and ensuring the load-bearing capacity and levelness of the floor plane. After the position of the expandable wing-shaped cabin 100 is adjusted and unfolded, the operator sets up multiple A-frame support frames 250 of the canopy system 200 between the two cabins in sequence. Specifically, the first connector 232 at the bottom of the side joint 230 is aligned and inserted into the first connecting seats 111 corresponding to the edges of the two container roof panels 110, and locked in place by the first fastener 233. Then, the tarpaulin 300 is covered above or below the entire tent frame, and a curtain 400 is installed at the passageway entrance, thereby connecting the two adjacent containers and the space between them to form a closed or semi-closed basic work unit 500. This basic work unit 500 can be used as a passageway, waiting area, or temporary treatment area.

[0063] like Figure 3 As shown, the actual distance between the two shelters may change due to site terrain or positioning errors. In this case, since both the top joint 210 and the side joints 230 are wide-angle adjustable structures, the operator only needs to adjust the angle between the support rod 220 and the joint to adapt the span of the A-frame support frame 250 to the actual distance, and then relock the joint. The support rod 220 has a redundant length design, meaning the maximum distance between its two end connectors is greater than the maximum allowable distance of the system. Therefore, even at the maximum distance, the roof can form an effective drainage slope to prevent water accumulation.

[0064] Specifically, see Figure 1 and Figure 3 Comparison between the two. Support rod 220 always has a constant length A. Figure 1 In this configuration, the distance between adjacent modular units 100 is B1. The total length of the two support rods 220, 2×A, is greater than B1. To form a "V"-shaped support frame 250 covering the area above B1, the angles of the top joint 210 and the side joint 230 are adjusted to C1, so that the "V"-shaped support frame 250 spans the distance B1 between the adjacent modular units 100. Figure 3In the middle, the support rod 220 remains at a constant length A, while the distance between the adjacent container 100 is B2. The total length of the two support rods 220, 2×A, is greater than B,2. In order to form a "V"-shaped support frame 250 covering the area above B2, the angle of the top joint 210 and the side joint 230 is adjusted to C2, so that the "V"-shaped support frame 250 spans the distance B2 between the adjacent container 100.

[0065] To obtain a larger operating space, the four biplane expandable 100 units can be arranged in two rows and two columns, such as... Figure 9 , Figure 10 As shown. First, two parallel, retractable connecting tubes 260, which can adaptively adjust to dimensional differences caused by variations in the spacing between the modular units or manufacturing tolerances, are erected above the central area of ​​the four-unit assembly. Second connecting pieces 263 are inserted into and fixed into the second connecting seats 112 at the corners of the four modular unit roof panels, forming a stable rectangular frame. The telescopic tubes 262 of the retractable connecting tubes 260 can be adjusted in length according to the actual spacing to adapt to minor changes in the distance between the modular units. Subsequently, the first connecting pieces 232 of the side joints of multiple A-frame support frames 250 are inserted into the first connecting seats 111 at the edge of the modular unit roof panel and the third connecting seats 261 on the retractable connecting tubes 260, covering the entire area above the four-unit assembly. Furthermore, X-shaped cross support rod assemblies 270 can be installed between adjacent A-frame support frames 250 to enhance the integrity and pressure resistance of the canopy structure. Finally, a large tarpaulin is placed over the tarpaulin to form a complete combined expansion unit 600 capable of accommodating multiple functional zones. Preferably, a spare tent 900 can also be set between the combined expansion units 600 to adapt to the expansion needs of multiple functional areas.

[0066] like Figure 13 As shown, the dual-wing expandable container 100 of the present invention preferably adopts a narrow-body design, and its external width in its non-expanded state is no more than half the width of a standard 20-foot container (i.e., approximately 1.2 meters). Thus, a 40-foot flatbed trailer can load four narrow-body dual-wing expandable containers 100 side-by-side, precisely forming all the container modules of a combined expansion unit 600, achieving efficient transportation of "four containers in one vehicle." If a 20-foot trailer is used, two containers can be loaded side-by-side. This design greatly reduces the number of transport vehicles and improves emergency delivery efficiency. For ease of sea transport, the external width of the dual-wing expandable container 100 is no more than 1 / 2 the internal width of a standard high-roof container, approximately 1.14 meters. Since the narrow-body container leaves less width for the container panels after retaining at least 800mm of equipment integration area, although it can be manufactured using various materials, high-strength, high-insulation carbon fiber sandwich composite panels are preferred when economically feasible.

[0067] like Figure 14As shown, one end face of the narrow-body, twin-wing expandable container 100 can selectively accommodate, from top to bottom, an air conditioning unit 151, an operation control panel 152, a power information configuration area 153 including a power interface, a sewage inlet 156, and a clean water inlet 155, facilitating centralized connection to external facilities. This end face can also be equipped with a ladder 150, which facilitates construction and maintenance while also protecting the aforementioned facilities. Doorways can be opened on the other end face and two side panels as needed.

[0068] As mentioned earlier, the bottom of the modular container is equipped with liftable casters 170, which can be lowered and moved and adjusted in a short distance on site; the bottom frames on both sides are equipped with support arms 160 that can be extended 90 degrees, which can be extended to support the ground and prevent the modular container from tipping over under the action of wind or other external forces.

[0069] Because it is intended for medical use, the interior needs to be used to integrate various medical devices, and a width of no less than 800mm is required to accommodate most medical devices, as well as standard enclosures with a width or length of 800mm.

[0070] like Figure 15 , Figure 16 As shown, depending on the scale of the rescue mission, multiple of the above-mentioned combined expansion units 600 can be arranged and combined to form mobile hospital systems of different sizes.

[0071] Figure 15 The demonstration showcased a small-scale hospital consisting of 7 combined expansion units 600, utilizing 28 functional modules, a dual-wing expandable modular unit 100, and integrated medical equipment and supplies within the modular unit. It was transported using only 7 flatbed trailers and could be quickly deployed to a working area of ​​approximately 1,600 square meters.

[0072] Figure 16 The exhibition showcased a larger-scale hospital, consisting of 48 functional modular units and integrated medical equipment and supplies, which were transported using only 12 flatbed trailers and could be quickly deployed to cover an area of ​​approximately 3,000 square meters.

[0073] Each 600-unit expansion module, when unfolded, provides approximately 220 square meters of working space. Compared to ordinary containerized shelters, the effective working area per transport is significantly expanded to 220 square meters, improving transport efficiency; compared to existing single-vehicle, single-expansion-module solutions, space efficiency is also improved. This greatly reduces the number of transport vehicles required and the standby storage area, significantly improving emergency response speed and system mobility. Utilizing pre-installed holes in the shelter's roof and quick docking with tent frame connectors, combined with modular tarpaulins, rapid construction of passageways and auxiliary working spaces is achieved, fully meeting the urgent requirements of emergency response. The stepless adjustment of the tent frame joints and the redundant length design of the tent poles allow the system to adapt to changes in site layout spacing within a certain range, fundamentally solving the problem of passageway construction caused by on-site positioning errors, and improving the system's spatial expansion and environmental applicability. The rigid plug-in connection method ensures the stability of the supporting structure. The redundant length and slope design ensure effective drainage of the tent roof under any permissible spacing, preventing water accumulation. After the joints are locked, a stable triangular support structure is formed. Optional X-shaped connecting rods and telescopic connecting tubes further enhance the rigidity and wind resistance of the overall frame. This invention is deeply integrated with the modular shelter system, with standardized interfaces. Components such as the tent frame and tarpaulin can be modularly produced, stored, transported, and managed, greatly facilitating system maintenance, rapid deployment, and large-scale application. The above description is merely a preferred embodiment of the invention and is not intended to limit the invention. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and principles of the invention, and these improvements and modifications should also be considered within the scope of protection of this invention.

[0074] To prevent rainwater from entering the expansion channel, the present invention provides a water inlet trough 800 on the outer edge of the roof of the container.

[0075] like Figure 4 In one preferred embodiment, the outer edge of the tarpaulin 300 is extended downward to below the edge of the roof of the container, and then the end of the outer edge of the tarpaulin 300 is flipped upward and fixed, so that the outer edge of the tarpaulin 300 hangs down naturally, forming a flexible water channel.

[0076] like Figure 5 In one preferred embodiment, a one-piece channel is directly stretched and formed by a technician on the aluminum profile of the outer frame of the roof panel 110 of the container as a permanent water channel, and rainwater falling from the edge of the tarpaulin 300 will be naturally guided into the one-piece channel.

[0077] Example 1: Construction of the modular shelter and canopy system. (Refer to...) Figures 1 to 14 This embodiment provides a structure that doubles the working space and allows for rapid deployment of a modular mobile hospital.

[0078] The core of the structure includes at least two biplane expandable modular units 100, a canopy system 200, and a retractable connecting pipe 260 between the modular units.

[0079] like Figure 1 , Figure 13 , Figure 14 As shown, the expandable double-wing container 100 features a narrow-body design. Its width in its non-expanded state is no more than half the width of a standard 20-foot container, approximately 1200 mm, facilitating the integration and transport of two or four containers side-by-side. For easy loading into shipping containers, the width in its non-expanded state is no more than half the width of a standard container's inner wall, approximately 1150 mm. The container includes a top plate 110 that flips upwards along the hinge point of the upper frame of the main body, a floor 140 that flips downwards along the hinge point of the lower frame of the main body, foldable support legs 141 located on the bottom surface of the floor 140, side plates 120 pivotally connected to the far end of the floor 140 and capable of flipping upwards to connect with the top plate, and end plates 130 pivotally connected to both ends of the main body of the container. When the container is expanded, these components together enclose the expanded interior space of the container. To reduce weight while ensuring structural strength and thermal insulation, the main body of the modular unit can be constructed using a welded frame made of high-strength steel or aluminum alloy profiles. The expandable panels can be made of aluminum alloy, fiberglass composite materials, or corrosion-resistant steel plates; carbon fiber composite panels are preferred for medical modular units. For easy on-site adjustments, the unit is equipped with adjustable casters 170 at the bottom; to prevent tipping, support arms 160 on both sides of the bottom frame can extend 90 degrees.

[0080] like Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, to construct the compartment space, the outer periphery of the roof plate 110 of the container is provided with multiple first connecting seats 111, and the four corners of the roof plate 110 are provided with second connecting seats 112. These connecting seats are preferably made of cast stainless steel or high-strength engineering plastics to ensure connection reliability and weather resistance.

[0081] like Figure 1 , Figure 7 As shown, the canopy system 200 includes multiple top joints 210, support rods 220, and side joints 230. The top joints 210 are connected to the near-center ends of the support rods 220 on both sides, and the far ends of the support rods 220 are connected to the side joints 230, together forming a stable A-frame support 250. To enhance overall integrity, a connecting cross tube 240 is provided between two adjacent top joints 210. The support rods 220 can be made of lightweight, high-strength aluminum alloy tubing or carbon fiber tubing, and the joint components can be made of reinforced nylon or die-cast aluminum alloy to achieve overall lightweighting and quick assembly / disassembly.

[0082] like Figure 11As shown, in order to further enhance wind resistance, a cross support rod assembly 270 is provided between two adjacent A-frame support frames 250. This assembly is hinged to the cross support rod seat 251 or cross support rod sliding seat 252 on the support rod 220, so that the entire canopy system 200 can be unfolded or folded and stored in one piece.

[0083] like Figure 1 , Figure 3 , Figure 8 As shown, to accommodate spacing errors in the placement of modular shelters on site, both the top joint 210 and the side joint 230 are designed with adaptive wide angles, allowing their connection angles to adjust with varying spacing. Simultaneously, the support rod 220 employs a redundant length design to ensure that, under the set minimum drainage slope angle, the total width between its two connecting parts still covers the maximum permissible spacing between modular shelters. Furthermore, as... Figure 8 As shown, the retractable connecting pipe 260 between the modular shelters has a sliding telescopic pipe 262 inside its cavity, making its length adjustable. Second connecting parts 263 for connecting the modular shelters are provided at both ends, and a third connecting seat 261 for connecting the canopy frame is also provided on the pipe body. This connecting pipe can adopt an aluminum alloy square tube sleeve structure and is equipped with a locking device to ensure stability after adjustment.

[0084] Example 2: Construction of the basic expansion unit 500, referring to... Figures 1 to 3 This embodiment describes the specific implementation method of the basic expansion unit 500.

[0085] Two expandable, biplane-shaped shelters 100 are arranged side-by-side and deployed according to functional requirements. Then, the pre-assembled A-frame support frame 250 is lifted, and by adjusting the angle of its side joints 230, the bottom connector 232 is aligned and fixed with the first connecting seats 111 corresponding to the edges of the two shelter roof panels 110. The connection method can be as follows: Figure 4 The insertion rod shown is designed with a first fixing element 233 to prevent it from falling off. Alternatively, it can be as follows: Figure 6 The screws are screwed in as shown. Finally, the tarpaulin 300 is placed over the frame consisting of multiple A-frame supports 250, and a curtain 400 is hung at the passageway entrance, thereby enclosing the two adjacent cabins and the space between them, forming a basic extension unit 500. The tarpaulin 300 is preferably made of high-strength polyester yarn coated with PVC or TPU on both sides, which has waterproof, flame-retardant, and tear-resistant properties. In this process, the joint angles of the tarpaulin system adaptively compensate for the deviation between the actual placement distance and the theoretical distance between the two cabins, achieving rapid construction.

[0086] Example 3: Construction of the Combined Expansion Unit 600 Reference Figure 9 , Figure 10 , Figure 12This embodiment describes a specific implementation method of the combined expansion unit 600.

[0087] Four expandable, two-winged modular shelters 100 are arranged in two rows and two columns. First, two parallel telescopic connecting pipes 260 are installed above the central area of ​​the four shelters. The length of the telescopic connecting pipes 260 is adjusted so that the second connectors 263 at both ends are aligned with and fixed to the second connecting seats 112 at the corners of the roof panels of the four shelters, thus forming a stable rectangular frame. This step, through the telescopic function of the connecting pipes, eliminates positioning errors in the row and column spacing of the four shelters.

[0088] Subsequently, multiple A-frame support frames 250 with cross-bracing rod assemblies 270 are sequentially deployed. A portion of the connector 232 at the bottom of its side joints is connected to the first connecting seat 111 at the edge of the container roof, and another portion is connected to the third connecting seat 261 on the retractable connecting pipe 260 between the containers. In this way, the canopy system completely covers the combined area between the four containers. Finally, the tarpaulin 300 is covered and the door curtain 400 is installed, thus forming a complete combined extension unit 600.

[0089] Example 4: Function Expansion and System Integration Reference Figure 14 , Figure 15 , Figure 16 This embodiment describes the functional expansion and integration of the system.

[0090] like Figure 14 As shown, one end face of the narrow-body container can integrate an air conditioning unit 151, a control operation area 152 with an operation panel, a power information configuration area 153 with a power interface and information interface, a sewage interface 156 connected to a sewage pipe, a water inlet 155 connected to a clean water pipe, and a ladder 150 for construction and maintenance. Doorways can be opened on the other end face and side panels to facilitate functional zoning and the organization of personnel and logistics. Preferably, a tool and accessory configuration area 154 is also provided in the lower part of the container to accommodate tools and accessories. To improve self-sufficiency in the field, such as... Figure 9 As shown, 700 solar panels can be installed on the top of the modular hospital, and the electricity from multiple modular hospitals can be stored in the grid to power critical equipment such as surgical and ICU facilities.

[0091] During on-site deployment, such as Figure 15 and Figure 16As shown, multiple basic expansion units 500 and / or combined expansion units 600 can be arranged and combined according to the needs of the rescue mission, and equipped with corresponding functional modules such as surgery, X-ray, ICU, or additional tents, to quickly form mobile hospital systems of different sizes and treatment capabilities. Between adjacent combined expansion units, a canopy system can also be erected using the methods of Embodiments 2 and 3 to form connecting passages and achieve connectivity of the internal spaces.

[0092] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the invention, based on the technical solution and concept of the invention, should be covered within the scope of protection of the invention.
