Figure 1 As shown, it includes a chassis assembly 1, a lifting cabin 2, a lifting mechanism 3, and a communication control unit;

[0037] The chassis assembly 1 carries the lifting cabin 2, the lifting mechanism 3 and the communication control unit, and includes a compartment 101 located on the upper part of the chassis assembly 1 for automatic driving during the evacuation and transfer of the wounded.

[0038] The unmanned vehicle for transporting the wounded has a folded state and an unfolded state; in the folded state, the lifting mechanism 3 is folded and the lifting cabin 2 is located inside the vehicle body 101; in the unfolded state, the lifting mechanism 3 is unfolded and the lifting cabin 2 is located on one side of the chassis assembly 1.

[0039] The lifting cabin 2 is a cabin-type structure used to carry the wounded; the lifting mechanism 3 is located at both ends of the lifting cabin 2 and is used to drive the lifting cabin 2 to switch between the unfolded state and the retracted state.

[0040] The communication control unit (not shown in the figure) is located inside the carriage 101 and is electrically connected to the chassis assembly 1, the lifting cabin 2 and the lifting mechanism 3 respectively. It is used to receive commands from the control center, communicate with the control center in real time, and control the actions of the chassis assembly 1, the lifting cabin 2 and the lifting mechanism 3.

[0041] It should be noted that the chassis assembly 1 adopts the existing wheeled or tracked off-road unmanned vehicle structure. By configuring the corresponding existing unmanned driving equipment and communication control unit, it has, but is not limited to, autonomous navigation, path planning, machine recognition, automatic driving, remote control and communication functions. Under the control of the communication control unit, it can cooperate with search and rescue drones (existing search and rescue drones) to achieve the functions of targeted rescue of the wounded, assisting the wounded to enter the lifting cabin 2, automatically lifting the wounded into the vehicle 101, and automatically returning to the rescue base or hospital gate. Here, the composition, structure and function of the chassis assembly 1 are not limited.

[0042] It should be noted that the communication control unit includes a communication module and a control module; the communication module uses existing communication equipment to achieve real-time communication with the control center; the control module preferably uses a PLC (PLC is an abbreviation for Programmable Logic Controller), but it can also be a circuit including at least one processor, a circuit including at least one microcontroller, or a combination of multiple circuits or chips, as long as it can achieve the corresponding function; it is understood that for those skilled in the art, the control circuit can also be a common circuit composed of amplifiers, comparators, transistors, MOSFETs, etc., to implement the corresponding function in a purely hardware manner.

[0043] It should be noted that the control center can be understood as a general term; it may include, but is not limited to, a rescue base, rescue headquarters, rescue vehicle, or hospital; it can remotely communicate with the unmanned vehicle to perform, but is not limited to, control actions, send command signals, and receive signals (real-time images, videos, audio, and positioning).

[0044] It should be noted that the carriage 101 is a box-type structure with open sides, preferably made of metal material with sufficient strength, to provide a carrying platform for this unmanned vehicle to carry the wounded, lift the cabin 2 and the lifting mechanism 3.

[0045] It should be noted that the lifting cabin 2 can be made of high-strength, lightweight materials such as carbon fiber and aluminum alloy.

[0046] In its specific implementation, this utility model provides a chassis assembly 1 that serves as a platform for the unmanned vehicle, facilitating unmanned patient evacuation and transfer. It also provides a lifting cabin 2, offering a safe, reliable, comfortable, and convenient transfer space for the injured, further enhancing patient evacuation and transfer capabilities. A lifting mechanism 3 automates and unmanned operations during the transfer of the injured from the ground to the vehicle, facilitating patient transfer. Finally, a communication control unit enables real-time communication with the control center, receiving instructions and controlling the unmanned vehicle's movements, further supporting unmanned patient evacuation and transfer. This utility model addresses the problems of low levels of intelligence and automation in existing patient evacuation methods, and the risk of secondary injury to the injured during the transfer process. It reduces the workload of rescue personnel and improves patient transfer efficiency during patient transfer.

[0047] In the embodiments provided by this utility model, such as Figure 2As shown, the lifting cabin 2 includes a cabin body 201, and the outer side wall of the cabin body 201 is a door 202; the two ends of the door 202 are movably connected to the outer side of the end walls of the cabin body 201 at both ends through a rotating mechanism 203, and can rotate relative to the cabin body 201 with the end of the rotating mechanism 203 away from the door 202 as the center;

[0048] The rotating mechanism 203 is provided with a rotating drive unit (not shown in the figure) at one end away from the hatch 202; the rotating drive unit is electrically connected to the control unit and can drive the rotating mechanism 203 to rotate.

[0049] It should be noted that the rotating mechanism 203 is preferably a rod-shaped structure, with one end fixedly connected to the middle of both ends of the hatch 202 via a shaft or pin structure, and the other end connected to the outer side of the end wall of the cabin 201 via a shaft or pin structure, passing through the end wall and entering the interior of the lifting cabin 2; the rotating mechanism 203 allows the hatch 202 to rotate relative to the cabin 201 with the other end of the rotating mechanism 203 as the center.

[0050] It should be noted that the rotary drive unit is preferably a stepper motor structure, which is located on the inner side of the end wall of the cabin 201. Its power output shaft and the shaft or pin structure that enters the inner side of the end wall of the cabin 201 are preferably driven by a pair of meshing gears (not shown in the figure) so as to drive the rotary mechanism 203 to rotate and thus drive the cabin door 202 to rotate.

[0051] In practice, an automatically rotating hatch 202 is installed, which enables automated control of the opening and closing of the hatch 202, further providing favorable conditions for unmanned casualty evacuation and transfer.

[0052] In one implementation, such as Figure 3 As shown, the lifting cabin 2 also includes a protective cover 204; the protective cover 204 is made of flexible material, with one edge fixed to the upper edge of the inner side wall of the cabin body 201, and the other edge fixed to the upper edge of the cabin door 202.

[0053] It should be noted that the protective cover 204 is preferably made of canvas, flexible PVC or other materials with functions such as foldability, rollability, rainproof and windproof; during the opening of the hatch 202, the protective cover 204 can be retracted to the inside of the lifting car together with the rotation of the hatch 202; during the closing of the hatch 202, the protective cover 204 can be laid flat above the lifting car under the action of the rotation of the hatch 202 to provide protection for the injured.

[0054] In practice, the protective cover 204 can provide the injured with a transfer space that shelters them from wind and rain and prevents external interference. The protective cover 204 is designed to be linked with the hatch 202 to extend and retract, enabling unmanned operation and further providing favorable conditions for the unmanned evacuation and transfer of the injured.

[0055] In the embodiments provided by this utility model, such as Figure 2 As shown, the lifting cabin 2 also includes seat belts 205; several of the seat belts 205 are all elastic strip structures, with one end set at the lower edge of the side wall inside the lifting cabin 2, and the other end set at the lower edge of the cabin door 202.

[0056] It should be noted that the seat belt 205 is preferably made of two cross-arranged elastic straps, rubber bands or other flexible materials with elasticity and sufficient strength; the connection between the two ends of the seat belt 205 and the lifting cabin 2 is preferably a buckle, hook or other detachable structure.

[0057] It should be noted that the end of the seat belt 205 connected to the hatch 202 can move when the hatch 202 is opened, or it can be fastened to the injured person's body when the hatch 202 is closed.

[0058] In practice, the safety belt 205 can provide bump protection for the injured and prevent them from being injured due to the bumps of the unmanned vehicle during the transfer. The safety belt 205 is designed to extend and retract in conjunction with the hatch 202 to achieve unmanned operation and further provide favorable conditions for the unmanned evacuation and transfer of the injured.

[0059] In one implementation, such as Figure 1 As shown, the lifting cabin 2 also includes a suspension support mechanism 206; the suspension support mechanism 206 is disposed on the lower end face of the lifting cabin 2 and includes at least four retractable suspension legs 2061; the suspension legs 2061 have elastic components inside, which can adjust their length and support force according to pressure changes.

[0060] It should be noted that the unmanned vehicle preferably has four suspension legs 2061 installed at the four corners of the lifting cabin. The upper end of each suspension leg 2061 is preferably fixed to the lower end of the floor plate of the lifting cabin 2 by riveting or threaded connection. Each suspension leg 2061 is equipped with a helical spring (elastic component) inside, which can adjust its own length and support force according to the pressure change, that is, the suspension leg 2061 can elastically extend and retract.

[0061] It should be noted that after the lifting cabin 2 is deployed, it is placed on the ground on one side of the unmanned vehicle by the lifting mechanism 3 (the lifting mechanism 3 exerts a certain downward pressure on the lifting cabin 2 when placing it). Due to the frequent outdoor environment, the ground may have undulations. When the lifting mechanism 3 places the lifting cabin 2 and presses it down, the contact time of each suspension leg 2061 with the ground will be different. The suspension leg 2061 on higher ground will contact the ground before the suspension leg 2061 on lower ground. The compression of each suspension leg 2061 will also be different due to the terrain. This can ensure that each suspension leg 2061 can contact the ground and provide support. It can also prevent a suspension leg 2061 from being suspended in the air and causing the vehicle to tilt when the injured person enters the lifting cabin 2.

[0062] In practice, the suspension support mechanism 206 can ensure that each suspension outrigger 2061 can contact the ground under the pressure of the lifting mechanism 3, thereby providing stable support for the lifting cabin 2 and preventing tilting when the injured person enters the lifting cabin 2.

[0063] In the embodiments provided by this utility model, such as Figure 2 As shown, an extension plate 207 is provided on the outer edge of the bottom plate of the lifting cabin 2; the bottom edge of the extension plate 207 is hinged to the outer edge of the bottom plate of the lifting cabin 2, and includes a tilting drive part 2071 and a tilting transmission part 2072.

[0064] The flipping drive unit 2071 is electrically connected to the control unit, and its power output end is connected to the power input end of the flipping transmission unit 2072; the flipping transmission unit 2072 is located at the connection between the extension plate 207 and the bottom plate of the lifting cabin 2, and its power output end can drive the extension plate 207 to rotate.

[0065] It should be noted that the tilting drive unit 2071 preferably has a structure of two stepper motors, which are set at both ends of the connection between the extension plate 207 and the bottom plate of the lifting cabin 2, and the power output end (i.e. the output shaft) is directly connected to the tilting transmission unit 2072.

[0066] It should be noted that the flipping transmission unit 2072 is preferably a shaft structure, which is movably fitted into the through hole on the edge of the base plate at the connection between the extension plate 207 and the base plate of the lifting cabin 2. Both ends are fixedly connected to the extension plate 207 and are driven to rotate by the flipping drive unit 2071.

[0067] It should be noted that the bottom edge of the extension plate 207 is hinged to the outer edge of the bottom plate of the lifting cabin 2 via a hinge structure.

[0068] It should be noted that the flip transmission unit 2072 receives the command action of the control module, drives the flip transmission unit 2072 to rotate, and then drives the extension plate 207 to swing outward around the hinge structure until the upper edge of the extension plate 207 contacts the ground, forming a transition slope between the ground and the bottom plate of the lifting cabin 2.

[0069] It should be noted that the upper surface of the extended plate 207 after it is unfolded is provided with several horizontally arranged rollers 2073, which can convert the sliding friction between the body and the extended plate 207 into rolling friction when the wounded person enters the lifting cabin 2.

[0070] In practice, the extension plate 207 can form a gentle slope between the ground and the bottom plate of the lifting cabin 2, avoiding steps between the lifting cabin 2 and the ground, making it easier for the injured to enter the lifting cabin 2 (the injured sometimes crawl to enter the lifting cabin 2 due to their injuries); the roller 2073 can reduce friction and save the injured's energy; the extension plate 207 adopts an automatic extension and retraction structure to realize unmanned operation, further providing favorable conditions for unmanned evacuation and transfer of the injured.

[0071] In one embodiment, a first camera (not shown) is installed inside the lifting cabin 2; the first camera is electrically connected to the control unit.

[0072] It should be noted that the first camera, preferably an existing high-definition camera, is used to capture images of the injured person entering the lifting cabin 2 and transmit the image information to the control module. The control module analyzes and determines whether the injured person has fully entered the lifting cabin 2 and adjusted their body and whether the seat belt 205 is in place, so as to send instructions for the next action.

[0073] In practice, the first camera works in conjunction with the control module to automatically identify and ensure that the injured are in a safe state, further providing favorable conditions for unmanned evacuation and transfer of the injured.

[0074] In the embodiments provided by this utility model, such as Figure 1 As shown, the lifting cabin 2 also includes a shock-absorbing unit 208; the shock-absorbing unit 208 is disposed on the lower end surface of the lifting cabin 2, and its bottom is in contact with the floor plate of the carriage 101 in the retracted state, which is used to reduce the impact of the ground on the injured and attenuate the vibration during the rear transport process.

[0075] It should be noted that the shock absorption unit 208 includes several buffer helical springs evenly arranged on the lower end face of the lifting car 2, and several shock dampers for attenuating the vibration generated by the helical springs. The shock dampers are preferably hydraulic dampers or metal friction dampers in the prior art, as long as they can attenuate the vibration and the overall height is within the allowable installation range, there are no restrictions here.

[0076] In one implementation, such as Figure 3 As shown, the lifting mechanism 3 includes a lifting bracket 301, a lifting drive unit 302, and a lifting transmission unit 303; one end of the lifting bracket 301 is fixed inside the carriage 101, and the other end is hinged to one end of the lifting drive unit 302; the other end of the lifting drive unit 302 is a power output end connected to the power input end of the lifting transmission unit 303, and is electrically connected to the control unit; the power output end of the lifting transmission unit 303 is connected to the outer end face of the end wall of the lifting cabin 2.

[0077] It should be noted that the lifting bracket 301 is preferably made of two metal materials welded together. The lower end is fixed to the floor plate of the carriage 101 by welding or threaded structure, and the upper end is connected to one end of the lifting drive unit 302 by ball joint hinge.

[0078] It should be noted that the lifting drive unit 302, preferably the electric cylinder structure in the prior art, includes a cylinder body 3021 and a push rod 3022. The end that is hinged to the lifting bracket 301 is the cylinder body 3021, and the end that is connected to the power input end of the lifting transmission unit 303 (hinged through a ball joint hinge) is the push rod 3022 (i.e., the power output end).

[0079] It should be noted that the lifting transmission unit 303 (which is a multi-link structure made of metal) includes:

[0080] The upper end of the drive rod 3031 (i.e. the power input end of the lifting transmission unit 303) is hinged to the power output end of the lifting drive unit 302.

[0081] One end of the drive shaft 3032 is fixedly connected to the lower end of the drive rod 3031;

[0082] The lower end of the lifting swing rod 3033 is fixedly connected to the other end of the drive shaft 3032, and the upper end (the power output end of the lifting transmission part 303) is hinged to the outer end face of the end wall of the lifting cabin 2.

[0083] It should be noted that after the lifting drive unit 302 receives the unfolding command from the control module, the electric cylinder push rod 3022 extends along the direction of the cylinder body 3021, pushing the drive rod 3031 to swing; the drive rod 3031 drives the transmission shaft 3032 to rotate, which in turn drives the lifting swing rod 3033 to swing; the upper end of the lifting swing rod 3033 drives the lifting cabin 2 to move outward of the carriage 101 until the lifting cabin 2 is lifted to the ground; when retracting, the action of the lifting mechanism 3 is the opposite of the above process.

[0084] In practical implementation, the lifting mechanism 3 adopts a lightweight structural design, and by optimizing the motion trajectory, it can effectively shorten the extension and retraction time of the lifting cabin 2. The lifting mechanism 3 utilizes the simple and stable characteristics of the multi-link structure, and through the drive rod 3031, the lifting swing rod 3033, and the transmission shaft 3032, the power of the lifting drive unit 302 can be transmitted to the lifting cabin 2. The mechanism connection is simple, with few moving joints, and the extension and retraction operation of the lifting cabin 2 can be completed in a single action. It abandons the structure of traditional rescue devices and solves the problems of many moving joints and complex operation of traditional rescue devices. It makes the rescue process labor-saving and fast, and can significantly reduce the volume and weight of each part of the lifting mechanism 3, achieving the purpose of lightweighting.

[0085] In the embodiment provided by this utility model, a second camera (not shown in the figure) is installed inside the carriage 101; the second camera is electrically connected to the control unit; as... Figure 1 As shown, there are two sets of lifting cabin 2 and lifting mechanism 3, respectively, which are installed on both sides of the carriage 101.

[0086] It should be noted that the second camera, preferably a high-definition camera from the existing technology (this is not a limitation), is used to collect images during the evacuation and transfer of the wounded and transmit the image information to the control module to provide image evidence for the evacuation and transfer of the wounded.

[0087] It should be noted that the lifting cabins 2 are arranged symmetrically on the left and right sides inside the carriage 101, which can rescue two injured people. Due to the arrangement of two lifting cabins 2, the lifting mechanisms 3 of the left and right lifting cabins 2 are arranged slightly differently to avoid mutual interference. This is reflected in the different lengths of the drive shafts 3032 on both sides. One drive shaft 3032 is longer, which provides space for the lifting mechanism 3 on the other side.

[0088] It should be noted that the process of this unmanned vehicle's transport is as follows: the search and rescue drone locates the injured person and sends location information to the unmanned vehicle, which then drives autonomously to the injured person's location; the control module controls the hatch 202 to open, and the injured person enters the lifting cabin 2 and adjusts their posture; the first camera transmits images to the control module, which determines that the injured person is lying down and closes the hatch 202; at the same time, the seat belt 205 is fastened to the injured person, and the protective cover 204 is automatically laid flat on top of the cabin 201 under the action of the hatch 202; the control module determines that the equipment and the injured person are in place based on the images transmitted by the first camera, sends instructions to the chassis assembly 1, returns to the control center, and completes the transport.

[0089] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0090] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
