Description

Technical Field

[0001] This invention relates to the field of emergency rescue equipment technology, specifically to a rapidly deployable double-chamber extended container for emergency rescue. Background Technology

[0002] In emergency rescue operations following earthquakes, floods, or public health emergencies, modular vehicles capable of rapid deployment and providing large-capacity operational space are among the core equipment. To balance road transport accessibility with the space requirements for parking operations, modular vehicles with a two-sided stretchable structure have become the mainstream technical solution. These modular vehicles are folded up during transport to comply with road regulations on width, and then unfold to the sides upon arrival at the scene to obtain additional medical or command space.

[0003] However, existing expandable modular hospital technologies present an irreconcilable contradiction between structural layout and actual user experience. Because the bottom of the modular hospital must retain the walking mechanism (axles, tires) and chassis beams, to ensure that the expandable cabin does not interfere with the chassis structure during retraction and extension, current designs typically have to position the floor of the expandable cabin significantly higher than the floor of the main cabin, or employ a high-mounted sliding rail solution. This structural compromise to avoid chassis interference directly results in an inherent step height difference between the main cabin and the expandable cabin after deployment. In emergency rescue scenarios where every second counts, this step severely hinders the rapid and unimpeded passage of medical stretchers, wheeled medical equipment, and emergency personnel, often requiring the installation of heavy transition ramps, which not only increases the workload of deployment and retrieval but also poses a tripping hazard.

[0004] Furthermore, traditional extendable modular units (MMUs) exhibit insufficient adaptability to harsh outdoor environments. On one hand, large-span cantilevered structures, lacking effective bottom rigid support, are prone to downward deflection, leading to difficulties in floor alignment or jamming during retrieval after prolonged use. On the other hand, existing sealing designs primarily focus on static water sealing, lacking dynamic protection mechanisms for the expansion and contraction process. Rainwater, mud, or snow adhering to the outer surface of the MMU can easily be carried into the main cabin during retrieval, compromising the cleanliness or sterility of the interior. Simultaneously, relying solely on onboard generators or mains power is insufficient to meet the energy self-sufficiency requirements for extended off-grid operations under extreme conditions.

[0005] Therefore, the purpose of this invention is to provide a rapidly deployable double-chamber extended container for emergency rescue, in order to overcome the shortcomings of the prior art. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a rapidly deployable dual-chamber extended cabin for emergency rescue, which solves the problem that existing extended cabins have steps (height differences) between the extended floor and the main cabin floor due to the need to avoid the chassis walking mechanism, thus hindering the unimpeded and rapid passage of emergency stretchers and wheeled equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rapidly deployable dual-compartment expandable container for emergency rescue, comprising a main compartment with a main compartment floor at its bottom and a hydraulic support mechanism installed below the bottom of the main compartment. Expandable compartments are symmetrically arranged on both sides of the main compartment, each with an expansion floor at its bottom. Guide mechanisms are located on both sides of the bottom of the main compartment to support and guide the expandable compartments in linear reciprocating motion relative to the main compartment. A drive mechanism connects the main compartment and the expandable compartments, driving the expandable compartments to switch between a retracted state and an expanded state. In the retracted state, the expandable compartments are housed within the main compartment; in the expanded state, the expandable compartments extend outward along the guide mechanisms.

[0008] Preferably, the guiding mechanism includes electric slide rails, which are laterally arranged on both sides of the main cabin, and one side of the movable seat of each of the two electric slide rails is fixedly connected to both sides of the extended cabin.

[0009] Preferably, the drive mechanism includes: A linear actuator is arranged at an angle inside the extended compartment. One end of the linear actuator is hinged to the column or beam of the main body, and the other end is hinged to the bottom or side wall frame of the extended body. The linear actuator pushes the extended cabin outward along the guide mechanism through a telescopic motion.

[0010] Preferably, a support platform is provided above the towing frame at the front end of the main body, a solar panel is provided on the upper part of the support platform, and multiple solar panels are laid on the top of the main body.

[0011] Preferably, the solar panel mounted on the support platform is connected to the support platform via a flip bracket; The flip-up bracket allows the solar panel to be angled between a storage position that fits against the surface of the support platform and a tilted, unfolded working position.

[0012] Preferably, the dual-cabin extended container further includes: A sealing system is vertically installed at the edge of the opening in the side wall of the main body; The sealing system includes an elastic sealing strip. When the extended cabin is fully extended, the inner column of the extended cabin presses against the sealing system to seal the gap at the connection.

[0013] Preferably, the hydraulic support mechanism includes multiple independently controlled hydraulic outriggers, which are respectively arranged in the four corner areas of the bottom of the main body, and hydraulic outriggers are also arranged at the bottom of the two extended bodies. Each of the hydraulic outriggers is equipped with an enlarged landing plate at its bottom for leveling the main cabin floor on uneven ground and bearing the overall weight of the container, thereby suspending or unloading the guiding mechanism and tires.

[0014] Preferably, the extended floor is movably installed at the bottom of the extended compartment; In the unfolded state, the upper surface of the extended floor and the upper surface of the main cabin floor are on the same horizontal plane, forming a connected space; During the retracted state and the unfolding process, the extended floor is kept at a horizontal height higher than the main cabin floor to avoid the chassis structure of the main cabin.

[0015] Preferably, the sealing system further includes horizontal wiper strips fixedly disposed at the top and bottom edges of the main body; The horizontal wiper strip remains in contact with the top and bottom surfaces of the extended compartment during its extension and retraction, preventing external rainwater and dust from entering the interior of the main compartment.

[0016] Preferably, the bottom of the main body is also integrated with a tire assembly, and the support platform is located at the front end of the main body in the direction of travel; the drive mechanism, the hydraulic support mechanism and the solar panel are all electrically connected to a central control unit located inside the support platform or inside the main body.

[0017] This invention provides a rapidly deployable double-chamber expandable container for emergency rescue. It has the following advantages: 1. This invention employs symmetrically fitted extended cabins on both sides in conjunction with a multi-stage telescopic guide mechanism. In the retracted state, the cabins on both sides can be completely housed within the outline of the main cabin, strictly complying with the width and height limits of standard road transport. In the extended state, inclined linear actuators drive the cabins to extend synchronously or independently to both sides, expanding the effective usable area to three times that of the transport state. This maximizes the working space at the emergency rescue site without sacrificing mobility and passability.

[0018] 2. This invention relies on the lifting and linkage mechanism of the extended floor to solve the problem of floor steps that are inevitable in traditional extended cabins due to chassis structure limitations. During the movement, the extended floor maintains a high position to avoid the wheels and frame. After being deployed, it automatically descends and docks with the main cabin floor with zero height difference, creating a continuous and barrier-free internal floor. This directly meets the tactical and technical requirements for the rapid pushing of emergency stretchers, the movement of wheeled medical equipment, and the high-frequency entry and exit of personnel.

[0019] 3. The integrated hydraulic support mechanism of this invention, combined with a large-area foot plate, enables the container to quickly and automatically level itself and completely unload its chassis on unhardened or uneven ground, eliminating the reliance on a pre-set foundation. Combined with a dynamic sealing system with horizontal wipers and an adjustable-angle solar power supply system integrated into the support platform, it can actively maintain a sealed and clean environment inside the container and ensure the energy self-sufficiency of the basic control system in disaster areas where there is no mains power supply, such as in wind, rain, sandstorms, or disaster areas. This improves the reliability of independent operation of a single unit. Attached Figure Description

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 4This invention provides a rapidly deployable dual-compartment expandable container for emergency rescue, comprising a main compartment 1, a main compartment floor 2 at the bottom of the main compartment 1, a hydraulic support mechanism 10 installed below the bottom of the main compartment 1, and expandable compartments 3 symmetrically arranged on both sides of the main compartment 1. Each expandable compartment 3 has an expandable floor 4 at its bottom. Guide mechanisms 5 are located on both sides of the bottom of the main compartment 1, which are used to support and guide the expandable compartments 3 to perform linear reciprocating motion relative to the main compartment 1. A drive mechanism 6 connects the main compartment 1 and the expandable compartments 3, which is used to drive the expandable compartments 3 to switch between a retracted state and an expanded state. In the retracted state, the expandable compartments 3 are housed within the main compartment 1; in the expanded state, the expandable compartments 3 extend outward along the guide mechanisms 5. Specifically, this embodiment proposes a rapidly deployable dual-compartment extended container for emergency rescue. Physically, the device consists of a main compartment 1 as the basic load-bearing unit, with the main compartment floor 2 fixedly laid on the bottom plane of the main compartment frame. A hydraulic support mechanism 10 is rigidly installed under the main beam of the main compartment 1 chassis, used to replace tires in bearing the load during operation. Two extended compartments 3 are axially symmetrically distributed on the left and right sides of the main compartment 1, each with an independent frame structure and an extended floor 4. A guide mechanism 5 is arranged laterally on the chassis, and through the cooperation of a slider and a slide rail, restricts the extended compartment 3 to linear reciprocating motion with only one degree of freedom along a direction perpendicular to the longitudinal axis of the main compartment 1. A drive mechanism 6 provides mechanical energy, converting electrical or hydraulic energy into thrust. In the retracted state, the two extended compartments 3 are completely retracted within the outline of the main compartment 1. At this time, the extended floor 4 is located above the main compartment floor 2, forming a stacked structure to meet the road transport clearance requirements. In the extended state, the drive mechanism 6 pushes the extended compartments 3 to move outward along the guide mechanism 5 until the predetermined stroke is reached.

[0024] The guiding mechanism 5 includes electric slide rails, which are laterally arranged on both sides of the main cabin 1. The movable seats of the two electric slide rails are fixedly connected to both sides of the extended cabin 3 respectively. Specifically, the guide mechanism 5 employs a heavy-duty electric slide rail assembly. This electric slide rail runs transversely through the main cabin 1 and is fixed to the chassis crossbeam. The electric slide rail includes a fixed rail and a moving rail base, wherein the mounting surface of the moving rail is rigidly connected to the bottom frame side beam of the extension cabin 3 via high-strength bolts. Rolling elements are integrated inside the electric slide rail to reduce the coefficient of friction. During operation, the electric slide rail not only constrains the movement trajectory but also bears the bending moment and shear force when the extension cabin 3 cantilever extends, ensuring the smoothness of the extension and retraction process and preventing the cabin from tilting or jamming.

[0025] The drive mechanism 6 includes: a linear actuator, which is arranged at an inclined angle in the internal space of the extended cabin 3; one end of the linear actuator is hinged to the column or beam of the main cabin 1, and the other end is hinged to the bottom or side wall frame of the extended cabin 3; the linear actuator pushes the extended cabin 3 to slide outward along the guide mechanism 5 through telescopic movement. Specifically, the drive mechanism 6 employs a linear actuator (such as an electric push rod or hydraulic cylinder) arranged in an oblique support structure. The fixed end of the linear actuator is hinged to the high point of the vertical column or top beam of the main body 1, and the movable end is hinged to the low point of the bottom or outer wall frame of the extension body 3. This triangular connection provides oblique thrust during the deployment of the extension body 3. Let the initial length of the linear actuator be... The extension amount is The angle between the actuator and the horizontal plane is The horizontal thrust obtained by the extended hull 3 Axial thrust of the actuator The relationship can be represented as: ; As the unfolding process progresses, the angle... The thrust gradually decreases while the horizontal thrust component gradually increases until it is fully deployed. This structure not only drives the displacement of the cabin but also forms diagonal braces after deployment, enhancing the structural rigidity of the extended section.

[0026] A support platform 7 is installed above the towing frame at the front end of the main body 1, and a solar panel 8 is installed on the upper part of the support platform 7. Multiple solar panels 8 are laid on the top of the main body 1. Specifically, at the leading edge of the main cabin 1 in the direction of travel, i.e., the traction end, a box-shaped support platform 7 is welded or bolted to it. The support platform 7 houses battery packs and inverters, among other electrical equipment. The solar panels 8 are arranged in two parts: the first part is laid flat and fixed to the top outer skin of the main cabin 1 and the extended cabin 3 to receive vertical sunlight; the second part is installed on the upper surface of the support platform 7. This layout utilizes the unused surface area outside the cabin to establish a distributed photovoltaic power generation system, providing power for the cabin's lighting, medical equipment, and drive mechanism 6.

[0027] The solar panel 8 installed on the support platform 7 is connected to the support platform 7 via a flip bracket; the flip bracket allows the solar panel 8 to be angled between a storage position that is in contact with the surface of the support platform 7 and a tilted and unfolded working position. Specifically, the solar panel 8 located on the support platform 7 is not directly fixed, but is connected to the platform via a flip-up bracket. The flip-up bracket includes a pivot and a locking mechanism. When the vehicle is in motion or stowed, the solar panel 8 is parallel and flush with the surface of the support platform 7 to reduce wind resistance and prevent damage from gravel. In the parked and unfolded state, the operator or a servo mechanism drives the flip-up bracket to rotate around the pivot, causing the solar panel 8 to form an angle with the horizontal plane. The included angle The latitude can be adjusted to ensure that the photovoltaic panel is as perpendicular as possible to the incident sunlight, thereby improving the photoelectric conversion efficiency.

[0028] The double-hull extended container also includes: a sealing system 9, which is vertically installed at the edge of the opening on the side wall of the main hull 1; the sealing system 9 includes an elastic sealing strip, which presses against the sealing system 9 when the extended hull 3 is fully extended into place, sealing the gap at the joint. Specifically, the sealing system 9 is vertically installed on the surrounding frame beams of the side wall opening of the main cabin 1. The core component of this system is a hollow or lip-shaped elastic sealing strip, typically made of EPDM rubber. When the extended cabin 3 moves outward to its maximum stroke under the action of the drive mechanism 6, the vertical columns inside the extended cabin 3 exert a lateral compressive force on the sealing system 9. This pressure causes the elastic sealing strip to deform elastically, filling the physical gap between the columns and the frame beams. This contact pressure must meet the following requirements: ; in, To ensure sealing contact pressure, The high infiltration pressure of external rainwater blocks the flow path of rainwater and air, thus achieving airtightness and watertightness of the cabin environment.

[0029] The hydraulic support mechanism 10 includes multiple independently controlled hydraulic outriggers, which are respectively arranged in the four corner areas of the bottom of the main cabin 1, and hydraulic outriggers are also arranged at the bottom of the two extended cabins 3; each hydraulic outrigger is provided with an enlarged landing plate at the bottom, which is used to level the main cabin floor 2 on uneven ground and bear the overall weight of the cabin, so that the guide mechanism 5 and the tires are suspended or unloaded. Specifically, the hydraulic support mechanism 10 consists of four main outriggers located at the bottom corners of the main cabin 1 and auxiliary outriggers located at the bottom outer sides of the two extended cabins 3. All outriggers are connected to a central hydraulic pump station. The ground contact plate at the bottom of each hydraulic outrigger increases the contact area with the ground and reduces the ground pressure. Before deployment, the four main outriggers extend downwards simultaneously to lift the tires off the ground, eliminating the effect of elastic deformation of the suspension system. Subsequently, the hydraulic outriggers located at the bottom of the extended cabins 3 extend downwards to support the ground after the cabins are deployed, preventing the extended cabins 3 from sagging due to torque. The system uses tilt sensor feedback data to independently adjust the extension and retraction of each outrigger cylinder until the overall platform's levelness error is controlled within the allowable range.

[0030] The extended floor 4 is movably installed at the bottom of the extended cabin 3; in the extended state, the upper surface of the extended floor 4 is at the same level as the upper surface of the main cabin floor 2, forming a connected space; in the retracted state and during the extension movement, the extended floor 4 is kept at a horizontal height higher than the main cabin floor 2, avoiding the chassis structure of the main cabin 1. Specifically, the extendable floor 4 is mounted on the base frame of the extendable cabin 3 via a multi-link hinge mechanism or a scissor lift mechanism. During retraction and sliding, this mechanism is in a raised state, locking the extendable floor 4 in a high position. , making ;in, The height is set at the highest point of the main cabin chassis and walking mechanism to avoid interference. Once the extended cabin 3 is fully deployed, this mechanism unlocks and drives the extended floor 4 to descend vertically to its lowest position. At this point, the height of the upper surface of the extended floor 4 is equal to the height of the upper surface of the main cabin floor 2. The gap between the two is extremely small, forming a continuous plane without steps, which facilitates the pushing of the stretcher and the movement of personnel.

[0031] The sealing system 9 also includes horizontal wiper strips fixedly installed at the top and bottom edges of the main body 1; the horizontal wiper strips always adhere to the top and bottom surfaces of the extended body 3 during the extension and retraction of the extended body 3, preventing external rainwater and dust from entering the interior of the main body 1; Specifically, the sealing system 9 adds horizontal wiper strips at the upper and lower horizontal edges of the opening in the main compartment 1. These wiper strips are made of highly abrasion-resistant rubber or polyurethane material, and their lip design incorporates pre-tightening force. During the dynamic process of the extended compartment 3 extending outwards or retracting inwards, the horizontal wiper strips remain in close contact with the upper surface of the top plate and the lower surface of the bottom plate of the extended compartment 3, sliding relative to each other. This structure functions similarly to a windshield wiper, mechanically removing rainwater, snow, dust, or leaves adhering to the surface of the extended compartment 3, preventing these external contaminants from being carried into the internal structure of the main compartment 1 during the compartment's recovery.

[0032] The bottom of the main body 1 is also integrated with a tire assembly, and the support platform 7 is located at the front of the main body 1 in the direction of travel; the drive mechanism 6, the hydraulic support mechanism 10 and the solar panel 8 are all electrically connected to the central control unit located inside the support platform 7 or inside the main body 1. Specifically, the bottom of the main cabin 1 integrates the axle, leaf spring suspension, and tire assembly, enabling it to tow. The support platform 7, serving as the front equipment compartment, is located above the tow bar. The central control unit (MCU / PLC) is located within the main cabin 1 or the support platform 7, connected to each actuator via wiring harnesses. Upon issuance of an operation command, the central control unit outputs control signals according to a preset timing logic: first, it controls the hydraulic support mechanism 10 to achieve leveling; second, it controls the drive mechanism 6 and guide mechanism 5 to unfold the cabin; and finally, it controls the extension floor 4 to descend into place. Simultaneously, the electrical energy collected by the solar panels 8 is electrically fed to the battery and distributed to the aforementioned electrical loads via the power distribution unit, achieving self-sufficiency of the energy system and integrated electromechanical-hydraulic control.

[0033] Working Principle: In transport mode, the two extended compartments 3 are completely housed within the interior space of the main compartment 1. The extended floor 4 remains vertically above the main compartment floor 2 to avoid obstructing the chassis structure. The hydraulic support mechanism 10 retracts, and the entire vehicle weight is borne by the tires. Upon arrival at the designated location, the hydraulic support mechanism 10 is activated first. The hydraulic outriggers located at the four corners of the main compartment 1 extend downwards until the footplates contact the ground. Subsequently, the hydraulic cylinders continue to apply thrust, lifting the main compartment 1 as a whole until the tires are unloaded or off the ground. At this point, the guide mechanism 5 disengages from the ground. The system independently adjusts the extension and retraction of the four hydraulic outriggers to correct the levelness of the main compartment 1, ensuring that the main compartment floor 2 is on a horizontal reference plane. Then, the deployment process begins. The central control unit commands the drive mechanism 6 to operate. Linear actuators, such as electric push rods or hydraulic cylinders, arranged at an angle within the compartment walls, extend, generating thrust that acts on the frame of the extended compartment 3. Under the thrust, the extended compartment 3 slides laterally outwards. At this point, the guide mechanism 5, fixed to the bottom of the main cabin 1, comes into play. Its multi-stage telescopic beams are pulled out step by step as the extended cabin 3 moves, forming a cantilever beam structure that provides rigid support to the extended cabin 3 from the bottom, bearing the cabin's own weight and torque. Throughout the outward displacement of the extended cabin 3, the horizontal wiper strips in the sealing system 9, located at the edge of the opening of the main cabin 1, continuously adhere to the top and bottom surfaces of the extended cabin 3, mechanically scraping away any attached rainwater or debris. When the drive mechanism 6 pushes the extended cabin 3 to its maximum stroke position, the inner columns of the extended cabin 3 press against the vertical sealing strips of the sealing system 9, completing the lateral sealing. Immediately afterwards, the extended floor 4 performs a lowering action. Through internal linkages or lifting components, the extended floor 4 descends from a high position to a low position until its upper surface is flush with the upper surface of the main cabin floor 2, eliminating the height difference and forming a continuous internal plane. In terms of power supply, in addition to the fixed solar panels 8 on the top of the main cabin 1 and the extended cabin 3, operators or mechanical devices will deploy the front-mounted solar panels 8 located on the support platform 7 above the forward towing frame. By adjusting the tilting bracket, this part of the solar panels 8 changes from a vertical state that is attached to the surface of the support platform 7 to an inclined state to obtain sunlight. The obtained electrical energy is stored and supplied to the power control equipment and drive mechanism 6 inside the support platform 7. The retraction process is performed in reverse order: the extended floor 4 is raised and reset first, the drive mechanism 6 retracts in the opposite direction to pull back the extended cabin 3, the guide mechanism 5 retracts into the chassis, and finally the hydraulic support mechanism 10 is retracted, and the cabin falls back onto the tires for towing.
