Description

[0001] Priority application This application claims priority to Chinese Invention Patent Application No. [202511394371.7] "A Mobile Emergency Medical Pod", filed on September 26, 2025, which is incorporated herein by reference in its entirety. Technical Field

[0002] This invention relates to the field of mobile operating rooms, and more specifically to a mobile emergency medical cabin. Background Technology

[0003] Mobile operating rooms represent a significant innovation in modern medicine, breaking the spatial limitations of traditional operating rooms and delivering high-level surgical capabilities directly to where they are needed. Currently, they primarily come in three forms: vehicle-mounted, container-type, and tent-type. These operating rooms, also known as emergency surgical units, are characterized by highly integrated, compact equipment packages that can be rapidly airdropped or carried on the back. They may include basic laminar flow devices and emphasize rapid deployment, making them the preferred choice for emergency scenarios such as war zones, disaster sites, and extremely remote areas where it is impossible to quickly establish fixed operating rooms.

[0004] Currently, the mainstream mobile operating rooms include vehicle-mounted medical pods and independently movable modular units. Vehicle-mounted medical pods are mainly designed for pre-hospital emergency care, rapid transport, and mobile medical services, thus emphasizing mobility and rapid response. Medical equipment is highly integrated into the vehicle platform, and space expansion is mainly achieved through lateral or overhead expansion. Independently movable modular units, on the other hand, are mainly used for setting up temporary hospitals, outdoor outposts, and other situations requiring a stable medical environment.

[0005] For example, patent application CN103330625A discloses an intelligent expandable vehicle-mounted mobile hospital to overcome the limitations of transport capacity and function in existing technologies, achieving the goal of providing timely and comprehensive medical support at disaster sites. When the mobile hospital is folded up for transport, its external cabin is a longitudinally expandable cabin, with an integrated air conditioning unit installed at the front. Four windows are provided on each of the left and right sides of the cabin, and a horizontal expansion synchronous drive mechanism is installed at the bottom. An upward expansion synchronous lifting mechanism is installed inside the cabin to drive the upward expansion. Spare parts, accessories, and toolboxes are located on the left and right sides of the chassis beam. A hydraulic tailgate is installed at the rear of the vehicle for loading and unloading equipment and supplies. A ramp and windows are provided at the rear of the cabin.

[0006] However, the aforementioned mobile hospital is primarily designed for simplified hospitals with multiple operating rooms. Therefore, it requires the construction of multiple operating cabins and relies on complex folding support structures for longitudinal or lateral expansion. In other words, although the mobile hospital adopts an integrated design of the cabin and vehicle body, resulting in good mobility, its complex structure cannot meet the need for independent and rapid deployment of medical cabins.

[0007] For example, patent application CN116537377A discloses a mobile, modular, multifunctional cabin, including a cabin base. The bottom wall of the cabin base is symmetrically provided with multiple moving wheels. The top of the cabin base is fixedly provided with a preoperative buffer area of ​​equal area. One side of the preoperative buffer area is pulled out and connected to a postoperative observation area, and the other side of the preoperative buffer area is pulled out and connected to a surgical area. The side wall of the preoperative buffer area located between the postoperative observation area and the surgical area is pulled out and connected to an examination area.

[0008] The aforementioned mobile hospital can only be moved short distances by traction equipment. When it needs to be moved to a more distant place, a separate transport vehicle is required. In other words, although it can be deployed quickly and independently, long-distance transport requires a separate vehicle, which has low mobility and cannot perform "pre-hospital emergency care" (such as surgery while transporting patients).

[0009] Therefore, there is an urgent need for a mobile operating room solution that combines high mobility and independent rapid deployment capabilities, enabling it to independently provide a stable endoscopic surgical operating space in complex field environments. Summary of the Invention

[0010] The purpose of this invention is to provide a mobile emergency medical cabin that partially solves or alleviates the above-mentioned shortcomings of the prior art, and has both mobility and independent rapid deployment capability, enabling the mobile medical cabin to be quickly deployed to places lacking the conditions for endoscopic surgery.

[0011] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution: A mobile emergency medical cabin includes a vehicle body and further includes: a first cabin detachably mounted on the vehicle body, and a second cabin connected to and coaxially mounted with the first cabin for performing surgical operations. The second cabin is located near the front of the vehicle body, and a third cabin is provided on one side of the second cabin, which is retractable in a direction perpendicular to the axial direction of the second cabin and connected to the second cabin. Both the first cabin and the second cabin are provided with multiple retractable support members and a retractable mobile roller mechanism. The first compartment includes: an unrestricted area for preparation space and a semi-restricted area for disinfection space, wherein the semi-restricted area is located between the unrestricted area and the second compartment; the length ratio of the unrestricted area to the semi-restricted area is 2:3; the length ratio of the third compartment to the second compartment is 15:23; and the width ratio of the third compartment to the second compartment is 2:5. When the third compartment is housed within the second compartment, the third compartment serves as a storage space for surgical equipment; the surgical equipment includes: a laparoscopic device; When the third compartment is deployed from one side of the second compartment, the third compartment serves as an extended space for surgical procedures.

[0012] Furthermore, the moving roller mechanism of the second cabin includes: a second sliding guide rail extending from the side of the second cabin to the bottom surface, and a slider disposed on the second sliding guide rail; the moving roller mechanism of the first cabin includes a retractable roller disposed at the bottom of the first cabin. When the support is in the retracted state, and the moving roller mechanism of the first and second cabins is in the retracted state, the first and second cabins are locked to the vehicle body by the positioning mechanism, so that the first cabin, the second cabin and the third cabin and the vehicle body serve as a mobile medical cabin. When the first compartment and the second compartment are unlocked from the vehicle body by the positioning mechanism, the support is lowered, and the slider slides to the bottom of the second compartment, the second compartment is pushed into the first compartment for storage by the slider with the assistance of an external force. Furthermore, when the second cabin is housed within the first cabin and the retractable rollers are extended onto the vehicle body, the first cabin is separated from the vehicle body via an external traction mechanism, allowing the first cabin, the second cabin, and the third cabin to function as independently movable mobile medical cabins.

[0013] Furthermore, the first compartment can move along the axis of the second compartment for storage or unfolding; specifically, the top of the second compartment is provided with a first sliding guide rail, and the top of the first compartment is provided with a moving wheel that cooperates with the first sliding guide rail; or, the second compartment can move along the axis of the first compartment for storage or unfolding, the inner wall of the top of the first compartment is provided with a first sliding guide rail, and the outer wall of the top of the second compartment is provided with a moving wheel that cooperates with the first sliding guide rail; When it is necessary to separate the first compartment, the second compartment and the third compartment from the vehicle body, first unlock the first compartment and the second compartment from the vehicle body, then push the second compartment or the first compartment so that the second compartment is housed in the first compartment, and then use a traction tool to separate the first compartment from the vehicle body. After the first cabin is placed on the ground, the support member at the bottom is extended, and then the second cabin is pulled out from the first cabin, and the third cabin is pulled out from the second cabin.

[0014] Furthermore, a locking mechanism is provided between the first compartment and the second compartment, the locking mechanism comprising: The mechanical locking assembly includes at least two pairs of locking pins and locking holes respectively disposed on the inner wall of the first compartment and the outer wall of the second compartment, and a first driving device for driving the locking pins; When the second compartment is in the retracted state, the first drive device drives the lock stop pin to pop out and insert it into the first lock hole on the second compartment; When the second cabin is in the extended state, the first drive device drives the locking pin to pop out and insert it into the second lock hole on the second cabin.

[0015] Furthermore, a locking mechanism is provided between the third compartment and the second compartment, the locking mechanism comprising: The mechanical locking assembly includes at least two pairs of locking pins and locking holes respectively disposed on the inner wall of the second compartment and the outer wall of the third compartment, and a first driving device for driving the locking pins; When the third compartment is in the retracted state, the first drive device drives the lock stop pin to pop out and insert it into the first lock hole on the third compartment; When the third compartment is in the extended state, the first drive device drives the locking pin to pop out and insert it into the second lock hole on the third compartment.

[0016] Furthermore, a first sliding guide rail is provided on the top / bottom / side wall of the third compartment, and a slider that cooperates with the first sliding guide rail is provided on the second compartment; correspondingly, the locking mechanism further includes: The auxiliary locking assembly includes a plurality of wedge-shaped blocks disposed on a first sliding guide rail along the third hull, and an elastic element disposed between the wedge-shaped blocks and the first sliding guide rail; When the third compartment moves to the storage position, the wedge block abuts against both sides of the slider under the action of the elastic element.

[0017] Furthermore, the medical cabin also includes: a displacement sensor installed on the third cabin body, and the auxiliary locking assembly also includes: a pneumatic cylinder or a hydraulic cylinder electrically connected to the control module; When the third compartment moves to the deployed position and the displacement sensor detects that the third compartment has moved, the control module controls the push rod of the pneumatic cylinder or hydraulic cylinder to extend and abut against the wedge block, so that the wedge block cannot be compressed, thereby forming a limiting component when the third compartment retracts.

[0018] Furthermore, the positioning mechanism includes: a plurality of locking pins disposed on the vehicle body, a second driving device for driving the locking pins, and a third locking hole correspondingly disposed at the bottom of the first compartment and the second compartment; and a control module electrically connected to the second driving device, and a human-machine interaction module for data communication with the control module; When the user selects the vehicle mode through the human-machine interaction module, the control module controls all the second drive devices to drive all the locking pins to cooperate with the third lock hole for locking; When the user selects to deactivate the vehicle mode through the human-machine interaction module, the control module controls all the second drive devices to drive all the locking pins to disengage from the third lock hole to unlock; Furthermore, when the third compartment is in the storage state, the support member is controlled to lift the first compartment and the second compartment away from the vehicle body by a first height. Then, the retractable roller is controlled to extend onto the vehicle body, and at the same time, the sliding member is controlled to slide along the second sliding guide rail to the bottom of the second compartment, so that the second compartment can be stored into the first compartment through the sliding member. Furthermore, when the second cabin is in the retracted state, the support component is retracted, and the first cabin is towed away from the vehicle body by an external traction device and pulled to the target location. Once the first cabin is towed to the target position, the second and third cabins are extended, and then the support is extended to lift the cabins off the ground and retract the retractable rollers.

[0019] Furthermore, a solar panel is installed on the top of the first cabin, and a power supply device that can be connected to an external power source is installed on one side of the first cabin.

[0020] Furthermore, the first cabin and the second cabin are provided with a lighting system, which includes: a linear light source disposed at the top of the second cabin, and / or a surface light source disposed at the top of the second cabin, and / or a point light source disposed at the top of the first cabin.

[0021] Beneficial effects: In this invention, by setting up a cabin that can be detached from the vehicle body and can be retracted and extended, the medical cabin can be used as a vehicle-mounted mobile medical cabin, or it can be independently deployed at the destination as a mobile cabin for a single surgical operation space (such as laparoscopic surgery and similar surgical operation spaces), thus simultaneously satisfying mobility and rapid deployment.

[0022] Based on the minimum operating radius and equipment size required for laparoscopic surgery, this invention sets the width ratio of the third compartment to the second compartment at 2:5. This ensures that, after deployment, it can accommodate at least two medical assistants performing side-lying operations, thus avoiding unnecessary excessive expansion of the space and resulting in an increase in the overall volume and weight of the medical cabin. Furthermore, it is precisely because the third compartment provides expandable surgical space that the first compartment 1 can be divided into two zones. This allows the semi-restricted area within the first compartment to focus on disinfection and sterilization, enabling the entire unit to continue operating as an independent, high-standard operating room even after detaching from the vehicle body.

[0023] To prevent significant slippage between the cabins during transport, especially in complex terrain such as uneven and bumpy areas, the medical cabin of this invention employs a locking mechanism between the relatively sliding second and third cabins (similarly, this locking mechanism can also be used between the first and second cabins). This prevents relative slippage between the cabins during transport (e.g., relative slippage between the second and first cabins in the folded state, or between the third and second cabins in the folded state, or between the third and second cabins in the unfolded state). Furthermore, sensors are used to detect the magnitude of relative slippage, triggering corresponding auxiliary locking components based on the detected slippage distance. This further ensures stability between the cabins. For example, in pre-hospital emergency care (i.e., transporting while performing surgery), once the sensors detect relative movement between the cabins and the movement distance reaches a certain threshold, the auxiliary locking components can be controlled to prevent relative slippage, thus ensuring the smooth progress of the surgery.

[0024] The medical cabin of the present invention uses two combined cabins in a movable and retractable manner. The second cabin is pulled out from the first cabin, and the combined cabin space is extended to expand the surgical operation space. Furthermore, a movable slide rail assembly is provided on the side of the second cabin. In use, the retracted slide rail assembly is moved from the side to the bottom, so that the entire medical cabin (the first cabin and the second cabin) can be moved at any time.

[0025] The medical cabin of the present invention is equipped with a ventilation device and a lighting system. The ventilation device includes two side vents located opposite the first cabin and the second cabin, which allow air to circulate on both sides. A top vent is also provided on the second cabin near the top of the first cabin. The lighting system meets the lighting requirements for surgical operations. The cabin is also equipped with a surgical tool storage cabinet and a washbasin, etc., to meet the needs of surgical operations.

[0026] The medical cabin of the present invention is not only movable and expandable in terms of surgical operation space, but also equipped with equipment to meet the needs of surgical operation. This surgical operation medical cabin provides convenience for areas lacking a surgical operation environment. Attached Figure Description

[0036] The emergency medical cabin described in this application incorporates a modular structure in its design to adapt to diverse and complex rescue and medical environments. Its core consists of three functional units (e.g., the second cabin serves as a surgical operating area, while the first and second cabins provide storage space for various surgical instruments and facilities). These modules can be combined and expanded to enhance adaptability to different scenarios. The entire system emphasizes convenient transportation and rapid deployment, meeting the needs of various environments such as disaster areas and resource-constrained hospitals.

[0037] This invention aims to address the pain points faced by most cities and remote areas, such as insufficient surgical resources, weak medical infrastructure, and slow emergency response. In reality, grassroots hospitals often struggle to perform complex surgeries due to equipment shortages, limited doctor capabilities, and insufficient funding, severely restricting the timeliness and quality of treatment for local patients. In extreme situations such as sudden disasters, existing medical resources are even more difficult to mobilize and respond quickly, leading to missed treatment windows and worsening conditions. Furthermore, most current medical equipment lacks mobile deployment capabilities, limiting its practicality in changing environments. Traditional mobile medical cabins are either vehicle-mounted integrated mobile medical cabins for single surgeries or large-volume modular cabins integrating multiple surgical procedures; that is, there is currently no dual-purpose medical cabin that can be deployed both vehicle-mounted and independently mobile for a single surgical operation space. In view of this, this application proposes a mobile emergency medical cabin for a single endoscopic surgery (such as laparoscopic surgery), which can not only be installed on a vehicle as a vehicle-mounted mobile medical cabin (i.e., highly mobile) but can also be moved independently from the vehicle to its destination for deployment (i.e., independent and rapid deployment).

[0038] Example 1: As Figures 1-3 As shown, this embodiment provides a mobile emergency medical cabin, including: a first cabin 1 detachably mounted on a vehicle body (e.g., the body of an existing vehicle-mounted mobile medical cabin), and a second cabin 2 connected to and coaxially arranged with the first cabin 1 for performing surgical operations (preferably, when the medical cabin is installed on the vehicle body, the second cabin 2 is close to the front of the vehicle body), wherein a third cabin 3 is provided on one side of the second cabin 2, which can extend and retract in a direction perpendicular to the axial direction of the second cabin 2 and is connected to the second cabin 2; both the first cabin 1 and the second cabin 2 are provided with a plurality of retractable support members 403 and a retractable mobile roller mechanism.

[0039] See Figure 2B The first cabin 1 includes: an unrestricted area for preparation space and a semi-restricted area for disinfection space, the semi-restricted area being located between the unrestricted area and the second cabin 2; the length ratio of the unrestricted area to the semi-restricted area is 2:3; the length ratio of the third cabin 3 to the length of the second cabin 2 is 15:23; the width ratio of the third cabin 3 to the width of the second cabin 2 is 2:5. When the third compartment 3 is housed within the second compartment 2, the third compartment 3 serves as a storage space for surgical equipment (such as laparoscopic surgical equipment, or other endoscopic surgical equipment). See [link to relevant documentation]. Figure 2A .

[0040] When the third compartment 3 is deployed from one side of the second compartment 2, the third compartment 3 serves as an extended space for surgical procedures. (See also...) Figure 1 .

[0041] To enable independent use both in vehicles and outdoors, and to facilitate rapid outdoor deployment, in some embodiments, the first compartment 1 can move along the axial direction of the second compartment 2 for storage or deployment, or the second compartment 2 can move along the axial direction of the first compartment 1 for storage or deployment. That is, the second compartment 2 is stored inside the first compartment 1, or pulled out and deployed from the first compartment 1.

[0042] Specifically, the top of the second cabin 2 is provided with a first sliding guide rail 5, and the top of the first cabin 1 is provided with a moving wheel or slider that cooperates with the first sliding guide rail 5 (that is, the moving wheel or slider can reciprocate along the extension direction of the first sliding guide rail 5); the top inner wall of the first cabin 1 is provided with the first sliding guide rail 5, and the top outer wall of the second cabin is provided with a moving wheel or slider that cooperates with the first sliding guide rail 5.

[0043] When it is necessary to separate the first compartment 1, the second compartment 2 and the third compartment 3 from the vehicle body, first unlock the first compartment 1 and the second compartment 2 from the vehicle body, then push the second compartment 2 or the first compartment so that the second compartment 2 is housed in the first compartment 1, and then use a traction tool to separate the first compartment 1 from the vehicle body. After the first cabin 1 is placed on the ground, the bottom support member 403 extends out, and then the second cabin 2 is pulled out from the first cabin 1, and the third cabin 3 is pulled out from the second cabin 2; similarly, the bottom support member 403 of the second cabin 2 extends out, thereby enabling rapid deployment of the medical cabin outdoors.

[0044] In some embodiments, the movable roller mechanism of the second cabin 2 includes a slide rail assembly 4. Specifically, the slide rail assembly 4 includes an L-shaped protective housing, an L-shaped second sliding guide rail 401 disposed within the protective housing and extending from the side of the second cabin 2 (the side near the front of the vehicle) to the bottom surface, and a slider 402 disposed on the second sliding guide rail 401, the slider 402 being provided with rollers. See [reference needed] Figure 4 .

[0045] When the slider 402 is located on top of the second sliding guide rail 401 on the side of the second cabin 2, the moving roller mechanism is in a retracted state; when the slider 402 is located near one end of the second sliding guide rail 401 at the bottom of the second cabin 2, the moving roller mechanism is in an extended state. At this time, the support 403 is in a retracted state, and the second cabin 2 can move on the vehicle body or the ground through the rollers on the slider 402.

[0046] Preferably, by providing this protective shell, when the first and second compartments are installed on the vehicle body, the bottom plane of the first compartment is flush with the bottom plane of the protective shell, thereby preventing any slight tilting between the first and second compartments. Of course, this protective shell has very high rigidity, thus ensuring support.

[0047] In some embodiments, the moving roller mechanism of the first compartment 1 includes: a retractable roller 404 disposed at the bottom of the first compartment 1. Specifically, a storage compartment can be provided at the bottom of the first compartment 1, and a retractable column (e.g., an electrically driven retractable column, not shown in the figure) can be provided inside the storage compartment, so that when the first compartment 11 needs to move, the retractable column can be controlled to extend downward and protrude outside the storage compartment, see [reference]. Figure 5 This allows the first compartment 11 to move on the vehicle body or the ground via retractable rollers 404 mounted on mounting bases at the bottom of the retractable column. When movement is not required, the retractable column can be retracted into the storage compartment.

[0048] Of course, in some other embodiments, in order not to occupy too much space within the first compartment 1, the aforementioned vertically retractable column is not used. Instead, a pivot (not shown in the figure) is set near an inner wall inside the storage compartment, so that the roller mounting base is rotatably installed inside the storage compartment via this pivot. When the roller is needed, the pivot is controlled to rotate, thereby causing the roller to extend and protrude outside the storage compartment. See [reference needed]. Figure 5 When the rollers are not needed, the shaft is controlled to rotate in the opposite direction, thereby causing the rollers to be stored in the storage compartment.

[0049] When the retractable support 403 (which can be a retractable support or support foot driven by a motor or cylinder at the bottom of an existing vehicle-mounted medical cabin) is in the retracted state, and the moving roller mechanism of the first cabin 1 and the second cabin 2 is in the retracted state, the first cabin 1 and the second cabin 2 are locked to the vehicle body by the positioning mechanism (at this time, it is in vehicle mode), so that the first cabin 1, the second cabin 2 and the third cabin 3 together with the vehicle body form a vehicle-mounted mobile medical cabin.

[0050] When the first cabin 1 and the second cabin 2 are unlocked from the vehicle body by the positioning mechanism, the support member 403 is lowered, and the sliding member 402 slides to the bottom of the second cabin 2, the second cabin 2 is pushed into the first cabin 1 for storage under the assistance of external force; and when the second cabin 2 is stored in the first cabin 1 and the retractable rollers at the bottom of the first cabin 1 are extended on the vehicle body, the first cabin 1 is separated from the vehicle body by an external traction mechanism, so that the first cabin 1, the second cabin 2 and the third cabin 3 can be used as independently movable mobile medical cabins.

[0051] In this application, the purpose of first storing the second compartment inside the first compartment is twofold: firstly, it simplifies the separation of the first, second, and third compartments from the vehicle body (for example, during separation, the support member 403 is retracted, but the rollers remain extended, allowing the first compartment 1 to move on the vehicle body, facilitating separation); secondly, it reduces the size after storage, making it easier to drag to complex terrain for rapid deployment. For instance, after the first compartment 1 is moved to the ground, the second and third compartments are unfolded, and the support member 403 is lowered again, while the retractable rollers 404 and the sliding member 402 are retracted, thus achieving rapid deployment.

[0052] When the second compartment 2 is stored inside the first compartment 1 and then towed to its destination, due to complex terrain, such as numerous potholes or steep slopes, the compartments may vibrate during towing, causing slippage between them and affecting towing efficiency. For example, the second compartment may need to be pushed back into the first compartment periodically, increasing both the difficulty of transportation and reducing efficiency. Alternatively, a separate mechanism such as binding ropes could be used to lock the second compartment inside the first compartment to prevent relative slippage, but this requires additional auxiliary tools, which also need to be stored separately. Therefore, this application provides a locking mechanism between the first compartment 1 and the second compartment 2. Specifically, the locking mechanism includes: The mechanical locking assembly includes at least two pairs of locking pins and locking holes respectively disposed on the inner wall of the first compartment and the outer wall of the second compartment, and a first driving device disposed on the inner wall of the first compartment for driving the locking pins. When the second compartment 2 is in the retracted state, the first drive device drives the lock stop pin to pop out and insert it into the first lock hole on the second compartment 2. When the second cabin 2 is in the extended state, the first drive device drives the locking pin to pop out and insert it into the second lock hole on the second cabin 2.

[0053] In some embodiments, the aforementioned locking pin and first drive device may employ an existing electronic lock structure, wherein the first drive device may be controlled by its independent controller or a pre-integrated control module.

[0054] Preferably, the first lock hole is located at the end of the top / bottom / side wall of the second compartment 2 near the front of the vehicle, while the second lock hole is located at the end of the top / bottom / side wall of the second compartment 2 away from the front of the vehicle.

[0055] Furthermore, corresponding sensors (e.g., infrared sensors or radio frequency sensors) can be set around the first and second keyholes respectively. When both the sensors at the first and second keyholes detect the first compartment (because the second compartment is housed inside the first compartment, the sensors at both keyholes will detect the first compartment), the control module is triggered to control the first drive device on the first compartment to drive the lock stop pin to pop out and insert it into the first keyhole on the second compartment. When only the sensor at the second keyhole detects the first compartment (because the second compartment is pulled out of the first compartment, the sensor at the second keyhole will detect the first compartment), the control module is triggered to control the first drive device to drive the lock stop pin to pop out and insert it into the second keyhole.

[0056] Similarly, a corresponding sliding guide rail and a moving wheel / slider are also provided between the third compartment 3 and the second compartment 2 (for example, a first sliding guide rail 5 is provided on the outer wall of the third compartment 3, and a moving wheel or slider that cooperates with the first sliding guide rail 5 is provided on the second compartment 2), so that the third compartment 3 can slide relative to the second compartment 2; and a locking mechanism is also provided between the third compartment 3 and the second compartment 2, the locking mechanism including: The mechanical locking assembly includes at least two pairs of locking pins and locking holes respectively disposed on the inner wall of the second compartment and the outer wall of the third compartment, and a first driving device disposed on the inner wall of the second compartment to drive the locking pins. When the third compartment is in the retracted state, the first drive device drives the lock stop pin to pop out and insert it into the first lock hole on the third compartment. When the third compartment is in the extended state, the first drive device drives the locking pin to pop out and insert it into the second lock hole on the third compartment.

[0057] Preferably, the first keyhole is located at the bottom, top, or side walls of the third compartment 3 near the external space, while the second keyhole is located at the bottom, top, or side walls of the third compartment 3 away from the external space. Furthermore, corresponding sensors can be installed around the first and second keyholes respectively. When both sensors at the first and second keyholes detect the second compartment (because the third compartment is housed within the second compartment, sensors at both keyholes will detect the second compartment), the control module is triggered to control the first drive device on the second compartment to eject the lock stop pin and insert it into the first keyhole on the third compartment. Conversely, when the sensor near the second keyhole detects the second compartment (because the third compartment is pulled out of the first compartment, only the sensor at the second keyhole detects the second compartment), the control module is triggered to control the first drive device to eject the lock stop pin and insert it into the second keyhole.

[0058] Example 2: Although a locking pin and locking hole are provided between the second and third compartments, with increased usage time, malfunctions, or poor road conditions, they may inevitably loosen or fail, causing the third compartment to slip relative to the second compartment. Furthermore, in vehicle mode, with the third compartment deployed, the stability requirements for the third compartment are even higher during surgical procedures while the vehicle is in motion (such as pre-hospital emergency procedures), because even slight slippage of the third compartment during surgery poses a threat to the surgical space. In view of this, this application also provides another medical compartment, which includes the components of the above embodiments. The difference is that this medical compartment also provides an auxiliary locking assembly between the third and second compartments. Specifically, the auxiliary locking assembly includes: Multiple wedge-shaped blocks 301 are provided along the extension direction of the first sliding guide rail 5 on the third hull 3, see [reference]. Figure 6A and Figure 6B An elastic element 302 is provided between the wedge block 301 and the first sliding guide rail 5 (specifically, one end of the elastic element 302 is fixed to the wedge block 301, and the other end is mounted on the first sliding guide rail 5 through the elastic element mounting seat 303), see [link to relevant documentation]. Figure 7 ; When the third compartment 3 moves to the storage position, the wedge block 301 abuts against both sides of the slider on the second compartment 2 under the action of the elastic member 302.

[0059] Furthermore, in other embodiments, the medical cabin further includes: at least one displacement sensor disposed on the third cabin (in some embodiments, the displacement sensor may be the sensor disposed at the first lock hole and / or the second lock hole as described above, or a displacement sensor disposed at other locations to detect the relative sliding of the third cabin relative to the second cabin may be used alone). The auxiliary locking assembly further includes: a plurality of third driving devices electrically connected to the control module, such as pneumatic cylinders or hydraulic cylinders. For example, pneumatic cylinders or hydraulic cylinders are respectively disposed on both sides of the first sliding guide rail 5 corresponding to the positions of the wedge blocks. Normally, the push rod of the pneumatic cylinder or hydraulic rod is in a retracted state. When it is necessary to intervene in the wedge block, the free end of the push rod can pass through the pre-set through hole on the first sliding guide rail 5 (and the through hole on the elastic element mounting seat 303, not shown in the figure), and then push out the wedge block, so that the two wedge blocks of the slider clamp the slider.

[0060] For example, in vehicle mode, after the third compartment moves to the deployed position, when the displacement sensor detects that the third compartment has shifted (i.e., the third compartment may retract), the control module controls the push rod of the pneumatic or hydraulic cylinder to extend and abut against the wedge block (or push out the wedge block, thereby stretching the elastic element), making the wedge block 301 incompressible, thus forming a limiting element when the third compartment retracts. Specifically, when the third compartment retracts, the first sliding guide rail 5 also moves along... Figure 6B The first sliding guide rail 5 moves in the direction indicated by the middle arrow, causing the A end of the first sliding guide rail 5 near the second compartment to gradually move away from the slider. When it moves a certain distance, the slider is clamped by the pushed-out wedge block, thereby locking the third compartment.

[0061] Preferably, the contact surface of the wedge block 301 that contacts the slider is provided with anti-slip texture made of flexible material (such as silicone or rubber) to increase friction.

[0062] In some embodiments, the positioning mechanism includes: a plurality of locking pins disposed on the vehicle body, a second driving device for driving the locking pins, and a third locking hole disposed at the bottom of the first compartment 1 and the second compartment 2 respectively; and a control module electrically connected to the second driving device and a human-machine interaction module for data communication with the control module; When the user selects the vehicle mode through the human-machine interaction module, the control module controls all the second drive devices to drive all the locking pins to cooperate with the third lock hole to lock; When the user selects to deactivate the vehicle mode through the human-machine interaction module, the control module controls all the second drive devices to drive all the locking pins to disengage from the third lock hole to unlock the vehicle. Furthermore, when the third compartment 3 is in the retracted state, the support member 403 is controlled to lift the first compartment 1 and the second compartment 2 away from the vehicle body by a first height. Then, the retractable roller is controlled to extend onto the vehicle body, and at the same time, the sliding member 402 is controlled to slide along the second sliding guide rail 401 to the bottom of the second compartment 2, so that the sliding member 402 can retract the second compartment 2 into the first compartment 1. Furthermore, when the second cabin 2 is in the retracted state, the support member 403 is retracted, and the first cabin is towed away from the vehicle body and pulled to the target location by an external traction device.

[0063] After the first cabin 1 is towed to the target position, the second cabin 2 and the third cabin 3 are extended, and then the support member 403 is extended to lift the cabin so that the retractable rollers are off the ground, and then the retractable rollers are retracted.

[0064] Example 3: This application also provides another mobile emergency medical cabin, which includes the components of any of the above embodiments. The difference is that in this embodiment, the control module controls the operation of the above auxiliary locking component based on the displacement Δd of the third cabin relative to the second cabin (that is, the displacement of the first sliding guide rail 5 relative to the slider on the second cabin) monitored in real time by the displacement sensor. Specifically, in this embodiment, multiple sets (for example, at least 4 sets, with two symmetrically arranged on the left and right as one set, and the specific number of sets can be set according to the actual size of the third cabin) of pneumatic cylinders or hydraulic cylinders are evenly arranged along the length direction of the first sliding guide rail 5 on the third cabin. When |Δd| < the first preset threshold Δd1 (e.g., 2mm), the control module determines it as a minor vibration, which is tolerable, and only monitors and records it without triggering active locking. Typically, if the road is a continuous gravel road, rough asphalt road, or a section with high-frequency, low-amplitude vibration, the vehicle body and cabin will undergo elastic deformation under continuous high-frequency vibration, which may cause a minute slippage between the track and the locking pin, which will be captured by the displacement sensor. Therefore, in this situation, to avoid unnecessary intervention, the hydraulic cylinder or pneumatic cylinder is not activated to push the wedge block, saving power while improving system adaptability and lifespan.

[0065] When Δd1≤|Δd|<second preset threshold Δd2 (e.g., 5mm), the control module determines it as a potential slippage risk and triggers one or two sets of pneumatic / hydraulic cylinders closest to the slider to push their corresponding wedges, thereby performing a "pre-warning" local locking to prevent displacement from escalating. Typically, when passing over large speed bumps, potholes, single obstacles on unpaved roads, or parking / driving on gentle slopes, the vehicle body and cabin experience upward acceleration the instant the wheels pass over the obstacle. This may cause the locking mechanism to experience instantaneous unloading. If there is a tolerance between the locking pin and the hole, slippage may occur, resulting in a slight slippage between the cabins. This slippage exceeds the normal tolerable range, thus posing a slippage risk. Furthermore, without intervention, the risk of further increase exists. Therefore, triggering the corresponding pneumatic or hydraulic cylinders to push the corresponding wedges strengthens the locking, aiming to nip the problem in the bud.

[0066] When Δd2 ≤ |Δd| < the third preset threshold Δd3 (e.g., 10mm), the control module determines it as a slippage fault and sequentially locks three sets of wedge blocks (i.e., the three sets closest to the slider) in the opposite direction of slippage, forming a "locking barrier" to provide greater anti-slip resistance. For example, during emergency avoidance, or in some special situations involving violent bouncing or side collisions, or after prolonged turbulence, the springs of the locking pins may become less effective, potentially leading to significant slippage between the cabins, which constitutes a clear fault or safety threat.

[0067] When |Δd|≥Δd3, the control module determines it as a severe displacement, issues the highest-level alarm (e.g., a warning via an integrated audible and visual module), and controls all available pneumatic / hydraulic cylinders to push all wedges into the maximum clamping state for global hard locking. When the displacement is extremely large (≥10mm), it means the lock may have failed, and global hard locking must be activated as a last line of defense, immediately triggering an alarm to request manual intervention.

[0068] In this embodiment, by equipping each or several sets of wedge blocks along the track with independently controlled pneumatic or hydraulic cylinders, and controlling them individually or in groups by the control module, precise spatial locking capability of "locking wherever you point" is achieved. That is, through closed-loop control of "sensing, multi-threshold decision-making, and distributed execution," different levels of locking methods are applied according to different sliding levels, thereby avoiding the increased power consumption caused by all devices locking simultaneously, especially for vehicle-mounted medical pods where sufficient power is required.

[0069] Furthermore, this embodiment also includes a vibration sensor that communicates with the control module. When the vibration sensor detects continuous turbulence, for example, when the amplitude or frequency of the control module signal exceeds a preset value, it triggers the motion sensor, which is normally in a dormant state, to enter the working state. The motion sensor compares the displacement Δd of the third cabin relative to the second cabin detected by the motion sensor with the above three preset thresholds, thereby triggering a corresponding number of pneumatic or hydraulic cylinders to push the corresponding wedge blocks to lock.

[0070] Of course, in some other embodiments, the aforementioned mechanical locking assembly may not be provided between the second and third compartments; only the aforementioned auxiliary locking assembly may be provided. The working principle is the same, and will not be repeated here. However, the difference is that, in order to ensure the stability of the third compartment, see [reference needed]. Figure 6C The control module treats two adjacent sets of wedge blocks as a whole. When Δd1≤|Δd|<second preset threshold Δd2, the control module triggers the two sets of pneumatic / hydraulic cylinders closest to the slider to push their corresponding two sets of wedge blocks as limiters on the third cabin retraction path. When Δd2≤|Δd|<third preset threshold Δd3, the control module controls the four sets of pneumatic / hydraulic cylinders closest to the slider to push their corresponding four sets of wedge blocks as limiters on the third cabin retraction path. When |Δd|≥Δd3, all cylinders are activated to push their corresponding wedge blocks.

[0071] Example 4: This application also provides another mobile emergency medical cabin, which includes all the components of any of the above embodiments. The difference is that, in this embodiment, the top of the first cabin is equipped with a solar panel 6, a power supply is provided on one side of the first cabin, and an energy storage device is also provided inside the first cabin. The solar panel powers various surgical instruments and other devices inside the cabin; in addition, an external power source can be connected to the outside of the cabin; the energy storage device is an alternative, used to power the medical cabin when neither of the above two methods can provide power.

[0072] In some embodiments, the first compartment and the second compartment are provided with multiple ventilation devices. The ventilation device on the left side of the second compartment forms a convection with the inlet of the first compartment, thereby forming a ventilation system, and the second compartment is provided with a ventilation device near the top of the first compartment. These three ventilation openings can form a stable ventilation circulation system.

[0073] In some embodiments, the first cabin and the second cabin are provided with a lighting system, the lighting system comprising: a linear lighting source disposed at the corner of the top of the second cabin, a surface light source (or point light source, i.e., the light emitted by the surface source has a large illumination area) disposed at the top of the second cabin, and a point light source (or point light source) disposed at the top of the first cabin.

[0074] In some embodiments, a display device is also provided on the outer surface of the first cabin 1.

[0075] Based on the above-mentioned medical cabin, this application also provides another medical cabin, which includes a vehicle body and a medical cabin of any one of the above embodiments one to four. The working principle and the connection relationship and cooperation method between the vehicle body and each component are as described in the above embodiments, and will not be repeated here.
