Abstract
Description
Technical Field
[0001] This application relates to the technical field of hospital beds, in particular to an intelligent transfer hospital bed system based on AGV navigation and its usage method. Background Art
[0002] A transfer hospital bed is a medical bed specifically designed for patient transfer. It has changed the traditional way of transferring patients, making the process of transferring patients convenient and fast, reducing the difficulties for doctors and nurses to transfer patients, and also alleviating the pain of patients during the transfer process.
[0003] However, due to the large number of emergency patients in clinical practice, various examinations are required, as well as transfers to the inpatient department. Currently, in the existing technology, patients themselves move from the hospital bed to the transfer bed, or family members help lift the patients to move to the transfer bed, and then the workers in the hospital sending department push the bed for examinations or hospitalization. This is very labor-intensive. Therefore, this application proposes an intelligent transfer hospital bed system based on AGV navigation and its usage method to make it more convenient for patients to move to the transfer bed. Summary of the Invention
[0004] Aiming at the deficiencies of the existing technology, the purpose of this application is to provide an intelligent transfer hospital bed system based on AGV navigation and its usage method to make it more convenient for patients to move to the transfer bed.
[0005] The above object of this application is achieved through the following technical solutions: An intelligent transfer hospital bed system based on AGV navigation includes a bottom plate, a support assembly installed on the bottom plate, a mounting plate installed at the upper end of the support assembly, a handling device installed on one side of the mounting plate for carrying the patient's mattress onto the mounting plate, and a transportation system installed on the bottom surface of the bottom plate for moving the bottom plate. The handling device includes a vertical plate installed on one side of the mounting plate, a driving electric cylinder installed on the side of the vertical plate away from the mounting plate and passing through the mounting plate, and a bearing plate installed on the output end of the driving electric cylinder for carrying the mattress.
[0006] By adopting the above technical solutions, when a patient needs an examination or transfer to the inpatient department, the patient can press the call bell beside the bed to call the nurse. The nurse and the worker in the sending department push the transfer hospital bed to the patient's bedside, aligning the side of the bearing plate away from the handling device with the gap between the patient's mattress and the bed board. Then, the driving electric cylinder is started to extend, so that the output end of the driving electric cylinder pushes the bearing plate into the gap between the mattress and the bed board, causing the mattress to move onto the bearing plate. Then, the worker in the sending department is on the side of the mattress away from the transfer hospital bed, and the nurse starts to contract the driving electric cylinder. At the same time, the worker in the sending department pushes the mattress towards the transfer hospital bed, causing the mattress to move onto the mounting plate along with the bearing plate. Then, the nurse and the worker in the sending department can push the transfer hospital bed with the patient for examination or transfer to the inpatient department, achieving the purpose of making it more convenient for patients to move to the transfer bed.
[0007] Furthermore, a connection assembly is provided at the connection between the mounting plate and the driving electric cylinder. The mounting plate is connected to the output end of the driving electric cylinder through the connection assembly. The connection assembly includes a connection plate fixedly arranged on the output end of the driving electric cylinder, a connection groove opened on the side of the connection plate away from the driving electric cylinder along the height direction of the connection plate, clamping grooves opened on both sides inside the connection groove along the height direction of the connection groove, a docking plate fixedly arranged on the side of the mounting plate close to the connection plate, and clamping pieces fixedly arranged on both sides of the docking plate and extending into the clamping grooves. One end of the docking plate away from the mounting plate extends into the connection groove. Both the clamping groove and the connection groove penetrate the bottom surface of the connection plate.
[0008] By adopting the above technical solution, although the setting of the handling device makes it more convenient for the patient to move onto the transfer bed, since the handling device needs to be used frequently, the bottom surface of the bearing plate will be worn after a period of use, resulting in a large gap between the bearing plate and the mounting plate. If the bearing plate is directly mounted on the output end of the driving electric cylinder, when the bearing plate transports the mattress, the weight of the mattress and the patient will act on the bearing plate, and the mounting plate will not provide support for the bearing plate, causing the connection between the bearing plate and the output end of the driving electric cylinder to be easily broken when the bearing plate is under pressure, resulting in the inoperability of the handling device. The setting of the connection assembly solves this technical problem. Through the setting of the connection assembly, when the bearing plate is worn, due to gravity, the bearing plate continues to fit with the mounting plate. At the same time, due to the cooperation of the clamping pieces and the clamping grooves, the output end of the driving electric cylinder can drive the bearing plate to move back and forth through the connection plate, improving the service life of the handling device without affecting the normal use of the handling device.
[0009] Furthermore, a limiting device for facilitating the bearing plate to pull the mattress is provided on the side of the bearing plate away from the driving electric cylinder. The limiting device includes a storage groove opened on the side of the bearing plate away from the driving electric cylinder, a storage plate inserted into the storage groove, a limiting plate rotatably arranged at one end of the storage plate close to the outlet of the storage groove, a support bending spring arranged between the storage plate and the limiting plate for keeping the limiting plate in a vertical state, and a limiting electric cylinder arranged on the side of the bearing plate close to the driving electric cylinder and with its output end extending into the storage groove. An installation groove is opened on the upper surface of the storage plate. One end of the support bending spring is located in the installation groove and fixedly connected to the storage plate, and the other end is fixedly connected to the limiting plate. The output end of the limiting electric cylinder is connected to the storage plate.
[0010] By adopting the above technical solution, although the setting of the handling device makes it more convenient for the patient to move onto the transfer bed, when the handling device transports the mattress onto the bearing plate, the worker in the sending part still needs to push the mattress on the side away from the transfer hospital bed, which is very inconvenient. The limiting device solves this technical problem. Through the setting of the limiting device, the storage plate and the limiting plate are in a folded state under normal conditions. After the mattress moves onto the bearing plate, the limiting electric cylinder is started to extend, and the limiting electric cylinder pushes the storage plate out of the storage groove. After the storage plate extends out, the supporting bending spring pushes the limiting plate to maintain a vertical state. Then the limiting electric cylinder is started to contract, so that the storage plate retracts into the storage groove, and at the same time drives the limiting plate to attach to the side of the mattress. At this time, when the handling device is started again, there is no need for manual pushing of the mattress on the side away from the transfer hospital bed, making the use of the handling device more convenient.
[0011] Further, the transportation system is an automatic guided vehicle based on AGV navigation, and the bottom plate is installed on the top surface of the automatic guided vehicle.
[0012] By adopting the above technical solution, the automatic guided vehicle is a driverless and computer-controlled mobile transportation device, belonging to mobile robots. AGV refers to a transport vehicle equipped with automatic guiding devices such as electromagnetic or optical ones, which can travel along the specified guiding path and has safety protection and various loading and unloading functions. It usually uses a rechargeable battery as the power source and controls its traveling route and behavior through a computer or an electromagnetic track. By setting the transportation system as an automatic guided vehicle based on AGV navigation, the nurse can input the target position on the automatic guided vehicle according to the patient's condition, and the transfer bed can be automatically controlled by the automatic guided vehicle to move to the target position. The nurse only needs to follow the transfer bed, further saving manpower.
[0013] Further, there are two groups of the support components, which are respectively arranged on the left and right sides of the bottom plate. Each group of the support components includes two support electric cylinders, which are respectively arranged on the front and rear sides of the bottom plate. A bearing device for carrying the replaced mattress is arranged between the two support electric cylinders of the group of the support components closer to the driving electric cylinder.
[0014] Further, the bearing device includes a driving motor and a fixing plate respectively installed on the opposite sides of the output ends of the two support electric cylinders, a rotating shaft arranged between the driving motor and the fixing plate, a supporting plate fixedly arranged on the axial surface of the rotating shaft for supporting the mattress, and a supporting device with the bottom surface of one end away from the rotating shaft of the supporting plate installed on the bottom plate.
[0015] Further, the supporting device includes a receiving sleeve fixedly arranged on the bottom plate and opening upward, a connecting rod inserted into the receiving sleeve, a tooth groove formed on one side of the receiving sleeve along the height direction of the receiving sleeve, and a rack meshing with the tooth groove on one side of the connecting rod. The end of the connecting rod away from the receiving sleeve is rotatably connected to the bottom surface of the supporting plate.
[0016] By adopting the above technical solution, although the setting of the handling device makes it more convenient for the patient to move onto the transfer bed, when the patient is transferred to the target bed, there may be a mattress on the target bed, which results in the nurse having to remove the mattress on the target bed before moving the mattress on the bearing plate to the target bed, which is very troublesome. The setting of the bearing device solves this technical problem. Through the setting of the bearing device, when the patient is transferred to the target bed, first start the supporting electric cylinder to rise, so that the mounting plate is higher than the mattress on the target bed, while the supporting plate is lower than the mattress on the target bed. Then start the driving motor to rotate upward until the end of the supporting plate away from the rotating shaft abuts against the bottom surface of the mattress on the target bed. At this time, the nurse can push the mattress on the target bed towards the supporting plate, so that the mattress moves onto the supporting plate. Then start the supporting electric cylinder to contract, so that the bearing plate moves above the bed board of the target bed. Then start the handling device to move the mattress with the patient lying on it to the target bed.
[0017] Further, a pressing device for enhancing the supporting force of the connecting rod is arranged on the side of the receiving sleeve away from the tooth groove.
[0018] Further, the pressing device includes a pressing plate attached to the surface of the connecting rod away from the rack and a pressing spring arranged on the surface of the pressing plate away from the connecting plate for pushing the pressing plate to press the connecting rod.
[0019] By adopting the above technical solution, through the setting of the pressing device, the connecting rod supports the supporting plate more firmly.
[0020] The usage method of an intelligent transfer hospital bed system based on AGV navigation applied to the above technical solution includes the following steps:
[0021] S1. Start the automatic guided vehicle to drive the transfer bed to move to the side of the patient;
[0022] S2. Start the supporting electric cylinder to align the side of the bearing plate away from the handling device with the gap between the mattress and the bed board of the patient. Then start the driving electric cylinder to extend, so that the output end of the driving electric cylinder pushes the bearing plate into the gap between the mattress and the bed board, so that the mattress moves onto the bearing plate;
[0023] S3. Start the limit cylinder to extend, so that the limit cylinder pushes the storage plate out of the storage groove. After waiting for the storage plate to extend, the supporting bending spring pushes the limit plate to maintain a vertical state. Then start the limit cylinder to contract, so that the storage plate retracts into the storage groove, and at the same time drives the limit plate to attach to the side of the mattress;
[0024] S4. Then start the driving cylinder to contract so that the mattress moves to the mounting plate along with the bearing plate;
[0025] S5. Then start the supporting cylinder to rise, so that the supporting plate is located above the bed board. Then start the driving motor to rotate downward, so that one end of the supporting plate away from the rotating shaft is butted against the bed board. At the same time, the mattress on the supporting plate slides onto the bed board along with the inclined supporting plate;
[0026] S6. Then start the supporting cylinder to descend, and then start the automatic guided vehicle to drive the transfer bed to move to the target position.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:
[0028] 1. Through the setting of the handling device, when a patient needs to be examined or transferred to the hospital, the nurse can be called by pressing the call bell beside the bed. The nurse and the worker in the sending department push the transfer hospital bed to the side of the patient, so that the side of the bearing plate away from the handling device is aligned with the gap between the patient's mattress and the bed board. Then start the driving cylinder to extend, so that the output end of the driving cylinder pushes the bearing plate into the gap between the mattress and the bed board, so that the mattress moves onto the bearing plate. Then the worker in the sending department is on the side of the mattress away from the transfer hospital bed. The nurse starts the driving cylinder to contract, and at the same time the worker in the sending department pushes the mattress towards the transfer hospital bed, so that the mattress moves to the mounting plate along with the bearing plate. Then the nurse and the worker in the sending department can push the transfer hospital bed with the patient to be examined or transferred to the hospital, achieving the purpose of making it more convenient for the patient to move onto the transfer bed.

Detailed implementation manners
[0038] The following further describes the present application in detail with reference to the drawings.
[0039] In an embodiment, referring to Figure 1 , an intelligent transfer hospital bed system based on AGV navigation mainly has a bottom plate 1 as a base to support the entire system; a support component is installed above the bottom plate 1 to provide necessary stability and support for the upper structure; further, a mounting plate 10 is installed at the top of the support component as an installation platform for various functional components. And a transportation system for driving the transfer hospital bed to move is installed on the bottom surface of the bottom plate 1, and more importantly, a handling device 2 is provided on one side of the mounting plate 10, and the handling device 2 is specially set up to smoothly and efficiently carry the mattress used by the patient onto the mounting plate 10.
[0040] The handling device 2 includes a vertical plate 20 vertically installed on one side of the mounting plate 10, and a driving electric cylinder 21 installed on the side of the vertical plate 20 away from the mounting plate 10 and whose piston rod can pass through the mounting plate 10. The output end of the driving electric cylinder 21 is connected to a bearing plate 22 specially used for bearing the mattress, and the design of the bearing plate 22 fully considers the size, weight of the mattress and the stability requirements during the handling process.
[0041] In practical applications, when a patient needs to undergo an examination or be transferred to another ward, they can simply press the call bell beside the bed to quickly contact the nurse. Subsequently, the nurse and the worker in the sending department will cooperate to move this intelligent transfer hospital bed system to the patient's bedside, ensuring that the side of the bearing plate 22 away from the handling device 2 can be accurately aligned with the gap between the patient's mattress and the bed board.
[0042] Next, by activating the extension function of the driving electric cylinder 21, its output end will smoothly push the bearing plate 22 to slowly insert into the gap between the mattress and the bed board until the mattress is steadily lifted and placed on the bearing plate 22. At this time, the worker in the sending department on the side of the mattress away from the transfer hospital bed will intervene in a timely manner and cooperate with the nurse: the nurse activates the contraction function of the driving electric cylinder 21, while the worker in the sending department gently pushes the mattress from the rear. The two work together to make the mattress smoothly slide onto the mounting plate 10 as the bearing plate 22 moves.
[0043] At this point, the entire handling process is completed. The nurse and the worker in the sending department only need to easily push the transfer hospital bed to take the patient to the destination for examination or transfer to the hospital for treatment. This innovative design not only greatly simplifies the process of patient transfer but also significantly improves the operation convenience and patient comfort, truly achieving the goal of making the movement process of the patient from the hospital bed to the transfer bed easier and more efficient.
[0044] Although the setting of the handling device 2 significantly improves the convenience of transferring the patient to the transfer bed, however, due to the frequent use of the handling device 2 in daily medical work, the bottom surface of the bearing plate 22 will inevitably experience a certain degree of wear. This wear gradually leads to a large gap between the bearing plate 22 and the mounting plate 10, which poses a potential risk to the handling process. Especially when the bearing plate 22 is directly installed at the output end of the driving electric cylinder 21, the weight of the mattress and the patient will be completely applied to the bearing plate 22, and the mounting plate 10 cannot provide the necessary support for the bearing plate 22. This stress situation is likely to cause the bearing plate 22 to deform under pressure, and then excessive stress will be generated at the connection between the bearing plate 22 and the output end of the driving electric cylinder 21, ultimately resulting in the fracture of the connection and making the entire handling device 2 unable to continue working.
[0045] To solve this technical problem, referring to Figure 2 shown in this embodiment, a set of connection components 3 is provided at the connection between the mounting plate 10 and the driving electric cylinder 21. This set of connection components 3 not only ensures the stable connection between the output end of the driving electric cylinder 21 and the mounting plate 10 but also improves the overall durability of the handling device 2. Specifically, the connection components 3 include the following key parts:
[0046] The connecting plate 30 is fixedly arranged at the output end of the driving electric cylinder 21. As the core component of the connecting assembly 3, it plays the role of transmitting the driving force and supporting the bearing plate 22.
[0047] The connecting groove 31 is located on the side of the connecting plate 30 away from the driving electric cylinder 21 and is opened along the height direction of the connecting plate 30.
[0048] The clamping grooves 32 are located on both inner sides of the connecting groove 31 and are opened along the height direction of the connecting groove 31.
[0049] The docking plate 33 is fixedly arranged on the side of the mounting plate 10 close to the connecting plate 30. As another key component of the connecting assembly 3, its design enables it to closely cooperate with the connecting plate 30 through the connecting groove 31.
[0050] The clamping pieces 34 are fixedly arranged on both sides of the docking plate 33 and extend into the clamping grooves 32, forming a tight fit with the clamping grooves 32, thereby enhancing the connection strength between the connecting plate 30 and the docking plate 33.
[0051] It should be noted that one end of the docking plate 33 away from the mounting plate 10 extends into the connecting groove 31, and both the clamping grooves 32 and the connecting groove 31 penetrate the bottom surface of the connecting plate 30. Such a design makes the installation and disassembly of the connecting assembly 3 more convenient.
[0052] Through the setting of this connecting assembly 3, even if the bearing plate 22 is worn due to long-term use, resulting in an increase in the gap between it and the mounting plate 10, however, due to the action of gravity, the bearing plate 22 can still closely fit on the mounting plate 10. At the same time, due to the tight fit between the clamping pieces 34 and the clamping grooves 32, the output end of the driving electric cylinder 21 can stably drive the bearing plate 22 to move back and forth through the connecting plate 30. This setting not only significantly improves the service life of the handling device 2 but also ensures the stability and reliability of the handling device 2 during long-term use, thus not affecting its normal use.
[0053] Although the design of the handling device 2 has greatly facilitated the transfer process of the patient from the hospital bed to the transfer bed, in actual operation, it is still necessary for the workers in the sending department to assist in pushing on the side of the mattress away from the transfer hospital bed, which undoubtedly increases the complexity of the operation and the labor cost. To solve this technical problem, referring to Figure 3 and Figure 4 as shown in this embodiment, a set of limiting devices 4 is arranged on the side of the bearing plate 22 away from the driving electric cylinder 21, aiming to realize the function of the bearing plate 22 to autonomously pull the mattress, thereby further improving the convenience and efficiency of the handling device 2.
[0054] This set of limiting device 4 is composed of multiple components that cooperate together to achieve its functions. First, a receiving groove 40 is opened on the side of the bearing plate 22 away from the driving electric cylinder 21, which is used to accommodate and hide the main components of the limiting device 4, while keeping the appearance of the handling device 2 neat and the functions concealed. Then, a receiving plate 41 inserted into the receiving groove 40 is arranged in the receiving groove 40. As the main part of the limiting device 4, the receiving plate 41 can extend out of the receiving groove 40 when needed to perform its limiting function.
[0055] At one end of the receiving plate 41 close to the outlet of the receiving groove 40, a limiting plate 42 is rotatably arranged. This limiting plate 42 can, after the receiving plate 41 extends out, attach to the side of the mattress in its vertical state, thereby playing a role in restricting the movement of the mattress. To ensure that the limiting plate 42 can maintain a vertical state when needed, in this embodiment, a supporting bending spring 43 is arranged between the receiving plate 41 and the limiting plate 42, and an installation groove is opened on the upper surface of the receiving plate 41. One end of the supporting bending spring 43 is located in the installation groove on the upper surface of the receiving plate 41 and is fixedly connected to the receiving plate 41, and the other end is fixedly connected to the limiting plate 42. In this way, when the receiving plate 41 extends out of the receiving groove 40, the supporting bending spring 43 can push the limiting plate 42 to automatically unfold to a vertical state.
[0056] In addition, to control the extension and retraction of the receiving plate 41, in this embodiment, a limiting electric cylinder 44 is arranged on the side of the bearing plate 22 close to the driving electric cylinder 21. Its output end extends into the receiving groove 40 and is connected to the receiving plate 41. By controlling the extension and contraction of the limiting electric cylinder 44, the extension and retraction actions of the receiving plate 41 can be precisely controlled.
[0057] In actual operation, after the mattress is transported onto the bearing plate 22, first start the limiting electric cylinder 44 to extend, pushing the receiving plate 41 to extend out of the receiving groove 40. As the receiving plate 41 extends out, the supporting bending spring 43 starts to function, pushing the limiting plate 42 to maintain a vertical state. Then, start the limiting electric cylinder 44 to contract again, so that during the process of the receiving plate 41 retracting into the receiving groove 40, the limiting plate 42 is simultaneously driven to attach to the side of the mattress. At this time, the limiting plate 42 has firmly clamped the mattress, enabling the handling device 2 to achieve smooth movement of the mattress without the need for manual pushing on the side of the mattress away from the transfer hospital bed after starting.
[0058] Through the design of this set of limiting device 4, this embodiment has successfully solved the problem of the need for manual assistance in pushing during the use of the handling device 2, making the use of the handling device 2 more convenient and efficient.
[0059] In this embodiment, the transportation system is an automated guided vehicle 11 based on AGV navigation. The bottom plate 1 is installed on the top surface of the automated guided vehicle 11. The automated guided vehicle 11 is a driverless and computer-controlled mobile transportation device, belonging to mobile robots. AGV refers to a transport vehicle equipped with automatic guiding devices such as electromagnetic or optical ones, capable of traveling along a specified guiding path, having safety protection and various transfer functions. It usually uses a rechargeable battery as the power source and controls its traveling route and behavior through a computer or an electromagnetic track. By setting the transportation system as the automated guided vehicle 11 based on AGV navigation, nurses can input the target position on the automated guided vehicle 11 according to the patient's condition, and the transfer bed can be automatically controlled by the automated guided vehicle 11 to move to the target position. Nurses only need to follow the movement of the transfer bed, further saving manpower.
[0060] Although the setting of the handling device 2 makes it more convenient for the patient to move onto the transfer bed, when the patient is transferred to the target bed, there may be a mattress on the target bed. This results in the nurse still having to remove the mattress on the target bed before moving the mattress on the carrier plate 22 to the target bed, which is very troublesome. To solve this technical problem, refer to Figure 5 、 Figure 6 and Figure 7In this embodiment, there are two sets of support components, which are respectively arranged on the left and right sides of the bottom plate 1. Each set of support components includes two support electric cylinders 12, which are respectively arranged on the front and rear sides of the bottom plate 1. A carrying device 5 for carrying the replaced mattress is arranged between the two support electric cylinders 12 of the set closer to the driving electric cylinder 21 among the two sets of support components. The carrying device 5 includes a driving motor 50 and a fixing plate 51 respectively installed on the opposite sides of the output ends of the two support electric cylinders 12, a rotating shaft 52 arranged between the driving motor 50 and the fixing plate 51, a supporting plate 53 fixedly arranged on the axial surface of the rotating shaft 52 for supporting the mattress, and a supporting device 6 whose bottom surface at the end of the supporting plate 53 away from the rotating shaft 52 is installed on the bottom plate 1. The supporting device 6 includes a receiving sleeve 60 fixedly arranged on the bottom plate 1 and opening upward, a connecting rod 61 inserted into the receiving sleeve 60, a tooth groove 62 arranged on one side of the receiving sleeve 60 along the height direction of the receiving sleeve 60, and a rack 63 meshing with the tooth groove 62 on one side of the connecting rod 61. The end of the connecting rod 61 away from the receiving sleeve 60 is rotatably connected to the bottom surface of the supporting plate 53. When the patient is transferred to the target bed, first start the support electric cylinder 12 to rise, so that the mounting plate 10 is higher than the mattress of the target bed, while the supporting plate 53 is lower than the mattress of the target bed. Then start the driving motor 50 to rotate upward until the end of the supporting plate 53 away from the rotating shaft 52 is butted against the bottom surface of the mattress of the target bed. At this time, the nurse can push the mattress of the target bed towards the supporting plate 53, so that the mattress moves onto the supporting plate 53. Then start the support electric cylinder 12 to contract, so that the bearing plate 22 moves above the bed board of the target bed. Then start the handling device 2 to move the mattress with the patient lying on it to the target bed.
[0061] In this embodiment, an extrusion device 7 for enhancing the supporting force of the connecting rod 61 is arranged on the side of the receiving sleeve 60 away from the tooth groove 62. The extrusion device 7 includes an extrusion plate 70 attached to the side of the connecting rod 61 away from the rack 63 and an extrusion spring 71 arranged on the side of the extrusion plate 70 away from the connecting plate 30 for pushing the extrusion plate 70 to extrude the connecting rod 61. Through the arrangement of the extrusion device 7, the connecting rod 61 supports the supporting plate 53 more firmly.
[0062] Such as Figure 8As shown, the specific implementation process is as follows: First, start the automatic guided vehicle 11 to drive the transfer bed to move to the patient's bedside. Then, start the support electric cylinder 12 so that the side of the bearing plate 22 away from the handling device 2 is aligned with the gap between the patient's mattress and the bed board. Then, start the driving electric cylinder 21 to extend, so that the output end of the driving electric cylinder 21 pushes the bearing plate 22 into the gap between the mattress and the bed board, causing the mattress to move onto the bearing plate 22. Then, start the limit electric cylinder 44 to extend, so that the limit electric cylinder 44 pushes the storage plate 41 out of the storage groove 40. After the storage plate 41 extends, the support bending spring 43 pushes the limit plate 42 to maintain a vertical state. Then, start the limit electric cylinder 44 to contract, so that the storage plate 41 retracts into the storage groove 40, and at the same time drives the limit plate 42 to attach to the side of the mattress. Then, start the driving electric cylinder 21 to contract so that the mattress moves to the mounting plate 10 with the bearing plate 22. Then, start the support electric cylinder 12 to rise, so that the supporting plate 53 is located above the bed board. Then, start the driving motor 50 to rotate downward, so that the end of the supporting plate 53 away from the rotating shaft 52 is butted against the bed board. At the same time, the mattress on the supporting plate 53 slides onto the bed board along the inclined supporting plate 53. Then, start the support electric cylinder 12 to descend, and then start the automatic guided vehicle 11 to drive the transfer bed to move to the target position.
[0063] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
