Description

Technical Field

[0001] This invention relates to the field of emergency rescue equipment technology, and in particular to a rapid-deployment expandable container for emergency rescue. Background Technology

[0002] In emergency medical rescue, disaster relief command, and temporary resettlement operations, rapidly deployable modular units have become critical infrastructure. Traditional emergency rescue modular units are mostly fixed-size container structures with limited internal space, making it difficult to adapt to the dynamic needs of complex tasks in terms of work area, functional zoning, and personnel capacity. Therefore, some modular unit designs with expandable capabilities have emerged in existing technologies to improve their space utilization.

[0003] However, the aforementioned existing technical solutions still have significant drawbacks. Existing top-expansion solutions often have flimsy structures, poor wind resistance, and lack a precise and reliable locking mechanism with the main cabin, posing safety hazards. Lateral expansion solutions are mostly made of soft tarpaulins or lightweight platforms, failing to provide a robust working surface and lacking stable mechanical support from the main cabin. More importantly, the connections between multiple cabins are usually just simple passageways, failing to achieve rigid structural integration. This results in insufficient overall rigidity of the assembly, poor stability in harsh environments, and difficulty in forming a truly unified and reliable large-scale rescue base. Therefore, there is an urgent need for an emergency rescue cabin that can expand more rapidly, has a more robust structure, more reliable connections, and excellent clustering capabilities. Summary of the Invention

[0004] The purpose of this invention is to provide a rapidly deployable expandable container for emergency rescue, in order to solve the technical problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a rapid-deployment expandable modular shelter for emergency rescue, comprising a main cabin and a top expansion cabin mounted on the main cabin, and further comprising: The main cabin base located at the bottom of the main cabin container has an extended floor installed on its outer edge via a locking hinge. The extended floor is configured to support the ground in the unfolded state and be connected to the top of the side wall of the main cabin base via a support diagonal rod, so as to form a triangular support structure at the corner of the extended floor. The top structural frame is located on the top of the main cabin of the container, and the inner docking frame is installed on it; and the extension cabin docking frame is located on the bottom plate of the top extension cabin mounting frame, which is corresponding to the inner docking frame, and the frame is equipped with a load-bearing top frame. A lifting support mechanism located in the inner cavity of the inner docking frame has an adjustable support component installed on its top, configured to support the load-bearing top frame; The adjustable support assembly includes: a support base installed on the top of the lifting support mechanism; a rack and pinion drive installed on the support base; and a deployable side wing support plate installed on both sides of the rack and pinion drive. The side wing support plate is provided with a secondary adjustment mechanism, and the secondary adjustment mechanism is equipped with a combination buckle via a guide rail. The bracket mounting component installed in each load-bearing top frame has a main body as the mounting body. Both ends of the mounting body are provided with engaging parts, configured to be supported and clamped between corresponding combination buckles, and the engaging parts are engaged in the slots of the combination buckles. The inter-module docking mechanism located on the side of the main module of the modular container is configured to enable parallel connection between the main modules of the modular container.

[0006] As a further embodiment of the present invention, the extended floor is further configured to cover the outside of the folding hatch provided on the main cabin of the container before it is unfolded.

[0007] As a further aspect of the present invention: the inter-module docking mechanism includes: A fixed docking plate that is fixedly installed on the side edge of the top plate of the main cabin of the container; A movable connecting plate, which is connected to the side edge of the fixed docking plate via a connecting hinge, is configured to connect to the adjacent main cabin of the container. The fixed docking plate has a cavity in the middle and a linear driver is installed thereon, which is configured to push the movable connecting plate.

[0008] As a further aspect of the present invention: the frame of the fixed docking plate is provided with a plurality of insertion hole cylinders, configured to strengthen the connection between the main cabins of the container by inserting and installing reinforcing rods between adjacent insertion hole cylinders.

[0009] As a further aspect of the present invention: the lifting support mechanism includes: The lifting base, lifting platform and lifting top plate are arranged from bottom to top; Several lifting rods mounted on the lifting base; and A guide sleeve installed on the lifting platform and corresponding to the lifting rod; The lifting rod is inserted into a guide sleeve and its top is fixed to the lifting top plate. A hydraulic drive cylinder is installed at the center line of the guide sleeve, and its pushing end is installed on the lifting top plate through a push rod connector.

[0010] As a further embodiment of the present invention: the bracket mounting component further includes: a lateral connecting edge provided on the side edge of the mounting body, which is fixedly mounted on the support plate of the top frame by a fastening mounting seat; and an extension attachment extended onto the engaging part, the extension attachment being provided with a locking hole; The side wing support plate has end mounting seats installed at both ends, and locking pins are installed on the end mounting seats through elastic buffer cylinders, configured to be locked in the locking holes.

[0011] As a further aspect of the present invention, it also includes: An air conditioning unit base located on the side edge of the main cabin of the modular container, connected to an airflow duct leading into the interior cavity of the main cabin; and Several ventilation openings are located on the outer wall of the top extension compartment.

[0012] As a further embodiment of the present invention: the two ends of the supporting diagonal rod are respectively hinged or detachably fixedly connected to the top of the side wall of the main cabin base and the corner of the extended floor plate.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects: The emergency rescue rapid-deployment expandable cabin provided by this invention achieves rapid and stable spatial expansion of the cabin in both vertical and horizontal directions through an integrated and modular mechanical structure design. After the bottom expansion floor unfolds via hinges, it forms a stable triangular support with the main cabin sidewall via diagonal braces, instantly creating an external working platform. The top expansion cabin is raised by a built-in precision lifting support mechanism, and automatically aligns, engages, and locks at multiple points using adjustable support components and mounting parts on the load-bearing frame, thereby safely increasing vertical space. Furthermore, the cabin's side is equipped with a modular inter-cabin docking mechanism, which, through a drive-type connecting plate and plug-in reinforcing rods, enables multiple cabins to be quickly and rigidly connected in parallel, combining into a large rescue unit.

[0014] The entire system integrates three major characteristics: rapid deployment, structural stability, and flexible networking. This significantly shortens the on-site deployment time of rescue equipment and improves emergency response speed. It also significantly improves the space utilization and functional adaptability of each compartment, meeting the work area and volume requirements of complex rescue missions. The triangular support, multi-point locking, and rigid docking design ensure the overall stability and safety of the expanded structure, enabling it to withstand harsh environmental loads. Finally, the highly modular and standardized design gives the container excellent cluster expansion capabilities, allowing for flexible configuration according to mission requirements to form a large-scale, integrated field emergency rescue base, greatly enhancing the efficiency and reliability of rescue operations.

[0025] The present invention will be further explained below with reference to specific embodiments.

[0026] Example 1; like Figure 1-2 As shown, this embodiment provides a basic form of a rapidly deployable expandable modular shelter for emergency rescue. The shelter includes a main cabin 1 as its main structure and a top expandable cabin 2 that can be mounted on it. The main cabin 1 is a rectangular box structure, with a main cabin base 11 fixedly connected to its bottom. This base supports the entire cabin and serves as the foundation for contact with the ground. Expandable floor panels 13 are hinged to the four outer edges of the main cabin base 11 via locking hinges 12. In the undeployed transport or storage state, the four expandable floor panels 13 fold upwards and fit tightly against the four outer facades of the main cabin 1. The foremost expandable floor panel 13 precisely covers the exterior of the hatch opening 16 on the front facade of the main cabin 1, where a foldable hatch door 15 is installed. After the extended floor 13 is fully extended and placed horizontally on the ground, an adjustable-length support rod 14 is diagonally connected between the mounting point at the top of the side wall of the main cabin base 11 and the outer corner of the extended floor 13, thus forming a stable triangular support structure between the main cabin side wall, the extended floor, and the support rod.

[0027] A top structural frame 31, made of robust welded profiles, is fixedly installed on the top of the main cabin 1 of the modular shelter. An inner docking frame 32 is formed in the central area of ​​this frame. The top extension cabin 2 consists of three layers from bottom to top: the mounting frame 21, the extension cabin body 22, and the top cover plate 23. Extension cabin docking frames 33 extend downwards from the four corners of the base plate of the mounting frame 21, their dimensions matching the inner docking frame 32 for initial alignment. A grid-shaped load-bearing top frame 34 is fixedly installed within the area enclosed by the extension cabin docking frames 33. A lifting support mechanism 4 is centrally installed within the cavity of the inner docking frame 32 of the main cabin 1. The top of this mechanism extends upwards and ultimately achieves precise docking and locking with the bracket mounting parts 7 within the load-bearing top frame 34 via adjustable support components 6 at its top, thereby stably raising and supporting the top extension cabin 2 on top of the main cabin 1. In addition, an air conditioner base 18 is provided on one side wall of the main cabin 1 for installing an external air conditioning unit. The air conditioner base 18 is connected to the cabin space through a flexible or rigid airflow duct 17. Several ventilation openings 24 with insect screens are evenly distributed on the four walls of the extension cabin 22 of the top extension cabin.

[0028] When the mobile shelter arrives at the rescue site and needs to be quickly deployed, the operator first releases the locking mechanism on the extension floor 13, grasps the outer edge of the floor and pulls it outward and downward, causing it to rotate around the axis of the locking hinge 12 until it is fully horizontally deployed and in contact with the ground. Then, the two ends of the support diagonal rod 14 are quickly connected and locked to the connection points on the side wall of the main cabin base 11 and the corner of the extension floor 13, forming a stable triangular support. Next, the lifting support mechanism 4 is activated, and its internal hydraulic drive cylinder 46 pushes the lifting top plate 43 upward, causing the adjustable support assembly 6 on it to move upward synchronously. The operator controls the rack and pinion drive 62 to drive the side wing support plates 63 on both sides to unfold outward, and adjusts the secondary adjustment mechanism 64 to move the combination buckle 66 to the predetermined engagement position. The lifting top plate 43 continues to rise until the combination buckle 66 contacts and surrounds the mounting body 71 of the bracket mounting component 7. At this point, the engaging parts 74 at both ends of the mounting body 71 are precisely embedded in the slots of the combination buckle 66. Furthermore, the operator can insert the locking pins 67 at both ends of the side support plate 63 into the locking holes 76 of the extension attachment 75 to complete the final mechanical locking. At this point, the top extension compartment 2 is securely raised and supported, and the vertical usable space of the container is expanded. Finally, by opening the folding hatch 15, personnel and supplies can smoothly enter and exit the container through the unfolded extension floor 13.

[0029] This embodiment utilizes a modular, articulated, and deployable design to enable rapid conversion between transport and operational states of the shelter space. The bottom extension floor 13 rotates and unfolds via hinges, expanding the original shelter's footprint and providing an external working platform and buffer space. The triangular structure formed by the supporting diagonal brace 14, the main cabin, and the floor is a classic stable mechanical structure that effectively transfers the load borne by the extension floor to the robust side walls and base of the main cabin, preventing excessive bending moments on the hinges. The lifting support mechanism 4 provides the main vertical lifting force, while the adjustable support assembly 6 and the bracket mounting parts 7 work together to achieve precise positioning and all-around horizontal restraint, ensuring that the top extension cabin 2 does not shift or sway after being lifted, resulting in high overall structural rigidity.

[0030] This embodiment provides a rapid and reliable modular shelter expansion solution. Through bidirectional expansion of the bottom floor and the top compartment, the actual usable area and volume of the shelter are significantly increased without substantially increasing transport volume or difficulty, thus improving the space utilization efficiency of rescue equipment. The deployment process is mechanized and step-by-step, simple and quick to operate, requiring no large amount of manual labor or heavy machinery assistance, making it ideal for rapid deployment in emergency situations. The expanded structure, through triangular supports and a precise top locking mechanism, ensures the overall stability and safety of the shelter, enabling it to adapt to uneven terrain and wind loads encountered in the field, ensuring the safety of personnel and equipment inside.

[0031] Example 2; as Figure 1 and Figure 3 As shown, this embodiment elaborates and optimizes the lateral parallel connection function between the main cabins 1 of the container based on the basic extended structure described in Embodiment 1.

[0032] On the top of the main cabin 1 of the modular shelter, inter-cabin docking mechanisms 5 are symmetrically installed on both sides (i.e., both sides along the length). The core of this mechanism includes a long, fixed docking plate 51 and a movable connecting plate 52. The fixed docking plate 51 is firmly fixed to the edge of the top plate of the main cabin 1 by bolts, and its inner side (facing inward) is connected to the top structural frame 31. On the outer long edge of the fixed docking plate 51, multiple connecting hinges 53 are hinged to one long edge of the movable connecting plate 52, allowing the movable connecting plate 52 to rotate outward or fold inward like a door panel, fitting against the outside of the fixed docking plate 51. Inside the fixed docking plate 51, a cavity is machined along its length, and a linear actuator 54, such as an electric push rod or hydraulic cylinder, is installed within the cavity. The end of its telescopic end is hinged to the inner side of the movable connecting plate 52, driving the expansion and folding of the movable connecting plate 52.

[0033] On the fixed docking plate 51, multiple pairs of through-hole cylinders 55 are spaced apart along its length. When the two main cabins 1 are brought side by side, their inter-cabin docking mechanisms 5 are positioned opposite each other. At this time, the movable connecting plates 52 of the two cabins extend outward to a horizontal state and may be temporarily connected at their ends by simple pins or fasteners, forming a continuous connecting bridge between the two cabins. To further enhance the integrity between the two cabins, the operator can insert the ends of multiple reinforcing rods into the corresponding through-hole cylinders 55 on the two fixed docking plates 51, thereby forming a rigid connection at multiple points. Other basic structures in this embodiment, such as the extended floor 13, the top extended cabin 2 and its lifting support mechanism 4, are the same as or similar to those in Embodiment 1.

[0034] When a large workstation or medical area consisting of multiple modular units needs to be set up at a rescue site, the main modules 1 are first transported to their designated locations according to the predetermined layout. Each module independently completes the deployment and lifting of the bottom extension floor 13 and the top extension module 2 as described in Example 1. Then, the inter-module docking operation is performed. The operator controls the linear actuator 54 on the side of the first main module 1 to push its movable connecting plate 52 to rotate and unfold outward until it reaches a horizontal position. Subsequently, the adjacent second main module 1 is operated, and its movable connecting plate 52 is also unfolded. The relative positions of the two modules are then finely adjusted so that the adjacent edges of the two unfolded movable connecting plates 52 are aligned, in contact, or slightly overlapped. The edges of the two movable connecting plates 52 can be connected and fixed by manual or automatic docking locks. Next, the operator inserts prefabricated reinforcing rods (which can be solid round rods or square tubes) into the aligned insertion holes 55 on the two fixed docking plates 51 in sequence, and fixes them at both ends with locking pins or nuts, thereby forming a strong transverse truss connection at the top of the module. This process can be carried out simultaneously on the other side of the modular container. After docking, the extended floor 13 of the adjacent modular containers will be almost on the same plane, forming a wider platform together. Personnel inside the containers can move freely on the extended platform through their respective folding hatches 15, or, as needed, open and connect passageways on the side walls of adjacent containers.

[0035] This embodiment significantly enhances the modular networking capability of a single extended modular unit, enabling rapid and reliable lateral connection of multiple modular units. It allows for flexible combination into clustered rescue camps of varying sizes and functional layouts, meeting the complex needs of large-scale emergency rescue. The drive-type movable connecting plate simplifies docking operations, improves efficiency, and provides a safe and flat top passage after docking, facilitating personnel inspections and cross-module equipment and pipeline laying. Multi-point rigid connections achieved through plug-in reinforcing rods ensure the integrated stability of the connected modules, enabling the assembly to withstand external loads as a whole.

[0036] Example 3; like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment illustrates the details of the cooperation and locking between the lifting support mechanism 4, the adjustable support component 6, and the bracket mounting component 7.

[0037] The lifting support mechanism 4 consists of three rigid platforms: a lifting base 41, a lifting platform 42, and a lifting top plate 43, arranged in parallel from bottom to top. The lifting base 41 is bolted to the base plate of the inner connecting frame 32. The lifting platform 42 is connected to the lifting base 41 via guide structures at its four corners, allowing for precise vertical guidance. At each of the four corners of the lifting base 41, a lifting rod 45 is vertically installed. Correspondingly, at each of the four corners of the lifting platform 42, four guide sleeves 44 are fixed, with the inner hole of each guide sleeve 44 precisely fitted onto the corresponding lifting rod 45, allowing the lifting rod 45 to slide freely within it. The tops of the four lifting rods 45 are connected to and support the lifting top plate 43. At the central axis position of each guide sleeve 44, a hydraulic drive cylinder 46 is also installed. The cylinder body of the hydraulic drive cylinder 46 is fixed on the lifting platform 42 or the inner docking frame 32, and its piston rod extends upward and is connected to the center area of ​​the bottom surface of the upper lifting top plate 43 through a push rod connector 47.

[0038] An adjustable support assembly 6 has a support base 61 mounted at the center of its upper surface. A rack and pinion drive 62 is mounted on the support base 61, and its output ends are connected to two large side support plates 63 on the left and right sides respectively via a rack and pinion mechanism. The side support plates 63 can move synchronously towards or away from each other in a direction perpendicular to the axis of the rack and pinion drive 62, realizing "expansion" and "retraction". Each side support plate 63 is equipped with a secondary adjustment mechanism 64, which may include another set of small linear modules. A combination buckle 66 is mounted on the slider of the secondary adjustment mechanism 64 via a guide rail 65. The combination buckle 66 has a "U" or "C" shaped cross-section, with the opening facing inward. At each of the two ends of the side wing support plate 63 away from the rack and pinion drive 62, there is an end mounting seat 68, on which a locking pin 67 that can be manually or electrically controlled is mounted via an elastic buffer cylinder 69 with a built-in spring. The axis of the locking pin 67 is perpendicular to the surface of the side wing support plate 63.

[0039] Within the support frame 34 of the top extension compartment 2, a bracket mounting piece 7 is installed corresponding to the position of each adjustable support assembly 6. The main body of the bracket mounting piece 7 is a thick mounting body 71, with downwardly bent lateral connecting edges 72 on its left and right sides, which are firmly fixed to the upper surface of the crossbeam of the support frame 34 by fastening mounting seats 73 and bolts. At both ends of the mounting body 71, hook-shaped engaging portions 74 extend downwards. On the outside of the engaging portions 74, an extension attachment 75 can also be attached by bolts, and the extension attachment 75 has a through locking hole 76 drilled on it. The width of the mounting body 71 is slightly smaller than the inner distance between the two side wing support plates 63 in the fully retracted state, and its length is parallel to the side wing support plates 63.

[0040] During the precision docking phase of lifting the top extension compartment 2, first ensure that the adjustable support assembly 6 is in the retracted state, i.e., the distance between the two side wing support plates 63 is minimal, the combination buckle 66 is in the inner starting position, and the locking pin 67 is in the retracted state. The lifting support mechanism 4 begins to lift, and the hydraulic drive cylinder 46 pushes the lifting top plate 43 upward, driving the entire adjustable support assembly 6 through the inner docking frame 32, gradually approaching the upper load-bearing top frame 34. When the upper surface of the combination buckle 66 approaches the lower surface of the mounting body 71, the lifting pauses. At this time, operate the rack and pinion drive 62 to drive the two side wing support plates 63 to simultaneously unfold outward until their inner guide rails 65 are roughly aligned with the two side edges of the mounting body 71. Then, the secondary adjustment mechanism 64 is activated, driving the combination buckle 66 to slide inward along the guide rail 65 (i.e. towards the mounting body 71) until the "U"-shaped groove of the combination buckle 66 supports and partially surrounds the side and bottom of the mounting body 71 from below. At the same time, the engaging part 74 at the end of the mounting body 71 is also embedded in the corresponding groove at the end of the combination buckle 66, completing the initial engaging and bearing.

[0041] After engagement, the hydraulic drive cylinder 46 of the lifting support mechanism 4 actuates again for final fine-tuning and lifting, completely detaching the supporting top frame 34 from its initial transport support. The weight of the entire top extension compartment 2 is then shared by multiple lifting support mechanisms 4. Finally, final locking is performed: the operator pushes or controls the locking pins 67 at both ends of the side wing support plate 63, causing them to extend forward with the assistance of the elastic buffer cylinder 69 and precisely insert into the locking holes 76 on the extension attachment 75. The elastic buffer cylinder 69 absorbs minor alignment errors and ensures that the pins maintain a certain preload within the holes, preventing accidental dislodgement. At this point, the top extension compartment 2 is lifted and supported vertically, constrained horizontally by the combined buckles 66, and redundantly locked at the ends by the locking pins 67, achieving a comprehensive and highly reliable connection.

[0042] This embodiment achieves automated and high-precision docking of the top extension compartment. The docking process is smooth and controllable, reducing the requirements for operator experience and physical strength, and avoiding structural damage from docking impacts. The multi-level adjustable support component design offers strong fault tolerance, compensating for minor dimensional errors caused by manufacturing, installation, or deformation, ensuring reliable docking under various working conditions. This significantly improves the reliability and safety of the connection. The snap-fit ​​mechanism bears the main load and provides multi-directional constraints, while the pin serves as the final guarantee against loosening and detachment, enabling the connection to withstand strong vibrations or impacts. This compact mechanism is integrated within the top frame of the main cabin, occupying no additional transport space, and is powerful yet discreetly efficient.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
