[0025] The present invention provides a nursing bed, the overall structure of which is as follows Figure 1 As shown, it includes a bed body 1, a lifting assembly 2, a translation assembly and a folding guardrail 21. The bed body 1 serves as the basic structure of the entire nursing bed, and is provided with slide rails 11 on both sides thereof. The slide rails 11 are used to install the sliders 12 of the translation assembly. The lifting assembly 2 is located in the middle area of the bed body 1 and is connected to the bed body 1 through a scissor-type connecting rod group 4. The translation assembly is arranged on both sides of the lifting assembly 2 and is used in conjunction with the slide rail 11. The folding guardrail 21 is installed on the two side frames of the bed body 1 through a hinge. One end of the support rod 22 is fixed to the bottom of the folding guardrail 21, and the other end is provided with a magnetic block 23. The magnetic block 23 is adsorbed and matched with the metal sheet 24 on the side frame of the bed body 1.
[0026] The specific structure of the lifting component 2 is as follows Figure 2As shown, it includes a base plate 3, a scissor-type connecting rod group 4 and a flexible support member 5. The base plate 3 is the core load-bearing component of the lifting assembly 2, and two symmetrically distributed scissor-type connecting rod groups 4 are provided at the bottom thereof. The upper and lower ends of the scissor-type connecting rod groups 4 are respectively connected to the base plate 3 and the nut through hinge points. Both ends of the bidirectional screw 9 are mounted on the side frames of the bed body 1 through bearings, and one end extends to the outside of the bed body 1 and is connected to the handwheel 10. A plurality of preset sockets are provided on the top of the base plate 3 for installing the connecting buckle 19. A pin is provided at the bottom of each connecting buckle 19, which is inserted into the socket of the base plate 3. A slot is provided at the top, and the end of the arc support bar 6 is embedded in the slot and fixed by a locking bolt 20. The arc support bars 6 are connected by an elastic connecting piece 7. The top of the arc support bar 6 is covered with an anti-slip layer 8. The surface of the anti-slip layer 8 is provided with a raised portion to increase friction.
[0027] The structure of the translation component is as follows Figure 3 As shown, it includes two parallel slide rails 11, a slider 12, and a meshing mechanism of a gear 13 and a rack 14. The slide rail 11 is fixedly mounted on the two side frames of the bed body 1, and a rack 14 is provided inside the slide rail 11. A gear 13 is provided at the bottom of the slider 12, and the gear 13 meshes with the rack 14. The side walls of the slider 12 are fixedly connected to the two sides of the lifting assembly 2. A drive motor 15 is installed on one side of the slider 12, and the output shaft of the drive motor 15 is coaxially connected to the gear 13. A guide column 16 is also provided on the outside of the slider 12, and the two ends of the guide column 16 are respectively fixedly connected to the slider 12 and the side frames of the bed body 1. A buffer sleeve 17 is provided on the outer side of the guide column 16, and a rubber ring 18 is provided on the outer wall of the buffer sleeve 17.
[0028] The cross-sectional structure of the flexible support member 5 is as follows: Figure 4 As shown, the curved support strips 6 comprise multiple curved support strips 6, elastic connecting strips 7, and an anti-slip layer 8. The curved support strips 6 are made of a flexible material, with their ends inserted into the slots of the connecting clips 19 and secured by locking bolts 20. The curved support strips 6 are connected by elastic connecting strips 7, which can adaptively adjust their curvature to the body's shape. The tops of the curved support strips 6 are covered with an anti-slip layer 8, which has raised surfaces to increase friction when in contact with the body.
[0029] The unfolded state of the folding guardrail 21 is as follows: Figure 5 As shown, the foldable guardrail 21 is hingedly mounted on the side frame of the bed 1. One end of a support rod 22 is fixed to the bottom of the foldable guardrail 21, and the other end is provided with a magnetic block 23. A metal sheet 24 corresponding to the magnetic block 23 is provided on the side frame of the bed 1. When the foldable guardrail 21 is unfolded, the magnetic block 23 is attracted to the metal sheet 24, maintaining the stability of the foldable guardrail 21.
[0030] The pressure detection system of the lifting assembly 2 includes a pressure sensor 25 and a control panel. The pressure sensor 25 is installed below the flexible support 5 and is connected to the control panel via a signal line. The control panel is installed on one side of the bed 1 and is used to display the pressure value detected by the pressure sensor 25.
[0031] During operation, the caregiver first rotates handwheel 10, which drives the bidirectional screw 9. This rotation causes the scissor linkage 4 to extend or retract, thereby raising or lowering the lifting assembly 2. Once the lifting assembly 2 reaches the desired height, the drive motor 15 is activated. The output shaft of the drive motor 15 rotates the gear 13, which rolls along the rack 14, thereby moving the slider 12 along the slide rail 11. The movement of the slider 12 causes the lifting assembly 2 to translate between the two sides of the bed 1, completing the patient transfer. During the movement of the slider 12, the cushioning sleeves 17 on the guide posts 16 contact the side frames of the bed 1. The rubber rings 18 within the cushioning sleeves 17 act as shock absorbers and position limiters. The flexible support member 5 is secured to the base plate 3 via a connecting clip 19 and a locking bolt 20, facilitating disassembly and cleaning. When deployed, the folding guardrail 21 maintains stability through the adsorption of the magnetic block 23 and the metal sheet 24, ensuring patient safety. The pressure sensor 25 detects the pressure distribution on the flexible support member 5 in real time and transmits the data to the control panel. Nursing staff can adjust the height and operating parameters of the lifting assembly 2 based on the pressure value to accommodate patients of different body types. To better enable those skilled in the art to fully understand and implement the present invention, the following supplementary explanation of the operating principles and implementation steps of the nursing bed is provided in conjunction with specific application scenarios.
[0032] In actual use, a caregiver first places the patient on the flexible support member 5. The flexible support member 5 is secured to the base plate 3 via connecting clips 19 and locking bolts 20. Its multiple curved support strips 6 are connected by elastic connectors 7. When the patient lies down, the curved support strips 6 adapt to the body's curves. Meanwhile, the raised surfaces of the anti-slip layer 8 increase friction when in contact with the body, preventing the patient from slipping during lifting or translation. This design ensures a smooth and comfortable lifting process.
[0033] Next, the caregiver rotates handwheel 10 to drive the bidirectional screw 9. The bidirectional screw 9 passes through the threaded hole at the intersection of the scissor linkage 4 and, through threaded transmission, drives the scissor linkage 4 to extend or retract. The upper and lower ends of the scissor linkage 4 are hinged to the base plate 3 and the bed frame 1, respectively. Therefore, the extension or retraction of the scissor linkage 4 causes the base plate 3 and the flexible support member 5 above it to rise and fall as a whole. This lifting operation allows the lifting assembly 2 to be adjusted to the appropriate height according to the care needs, thereby reducing the operating burden on the caregiver.
[0034] When the lifting assembly 2 is raised and lowered to the target height, the caregiver starts the drive motor 15, and the output shaft of the drive motor 15 drives the gear 13 to rotate. The gear 13 meshes with the rack 14, which is fixedly mounted inside the slide rail 11. Therefore, when the gear 13 rolls along the rack 14, the slider 12 moves along the slide rail 11. The slider 12 is fixedly connected to both sides of the lifting assembly 2 through a connecting plate, so the movement of the slider 12 can drive the lifting assembly 2 as a whole to move horizontally between the two sides of the bed 1. This process realizes the transfer of patients from one side of the bed to the other, without the need for the caregiver to perform too much auxiliary operations, significantly reducing labor intensity.
[0035] As slider 12 moves along rail 11, cushioning sleeve 17 on guide post 16 contacts the side frame of bed 1. A rubber ring 18 is embedded within the inner wall of cushioning sleeve 17, providing shock absorption and position limiting, effectively reducing vibration and noise during slider 12 movement and enhancing operational stability. Furthermore, the design of the sliding guide ensures that slider 12 maintains a precise, straight trajectory during movement, preventing any jamming or instability caused by misalignment.
[0036] During the lifting and translation process, the pressure sensor 25 monitors the pressure distribution beneath the flexible support member 5 in real time and transmits this data to the control panel. Caregivers can use the pressure values displayed on the control panel to determine the patient's body type and force distribution, and subsequently adjust the height or operating parameters of the lifting assembly 2. For example, for larger patients, the lifting height can be appropriately lowered to enhance stability; for smaller patients, the lifting height can be increased to facilitate transfer. This dynamic adjustment mechanism based on pressure feedback enhances the adaptability of the nursing bed to patients of varying body types.
[0037] Furthermore, after the patient is transferred, the caregiver can use the foldable guardrail 21 to ensure the patient's safety. The foldable guardrail 21 is hingedly mounted on the two side frames of the bed 1. One end of the support rod 22 is fixed to the bottom of the foldable guardrail 21, and the other end is equipped with a magnetic block 23. When the foldable guardrail 21 is unfolded, the magnetic block 23 attaches to the metal sheet 24 on the side frame of the bed 1, keeping the foldable guardrail 21 stable. This design not only enhances the safety of the bed but also allows caregivers to quickly deploy or retract the guardrail, improving operational convenience.
[0038] In summary, the present invention achieves a complete process of patient lifting, translation, and safety assurance through the coordinated operation of the lifting assembly 2, translation assembly, and folding guardrail 21. The design of each component is centered around the goals of simplifying the structure, improving adaptability, and enhancing ease of operation. This addresses the complex structure, insufficient adaptability, and large operating space requirements of existing nursing beds in practical applications. The combination of the above-mentioned specific implementation steps and principles will enable those skilled in the art to clearly understand and implement the technical solutions of the present invention.
[0039] The four corners of the bottom of the bed body (1) are provided with universal drive wheels with encoders, the hub motor and electromagnetic brake are integrated in the universal drive wheels, and a liftable hydraulic support foot is provided in the middle. The universal drive wheels realize the plane movement of the entire bed through differential control, and the movement trajectory is generated by the fusion calculation of laser radar and encoder data. The hydraulic support foot is retracted during movement and extended to bear weight during positioning, forming a collaborative load-bearing system with the drive wheel group.
[0040] A distributed pressure sensing grid is provided under the flexible support member, and data is input into the AI decision module to generate body adaptation parameters; the AI decision module integrates a path planning algorithm to dynamically generate the optimal energy transfer path based on obstacle data.
[0041] When automatic transfer is required: 1. The nurse gives the voice command "prepare for transfer", the AI system executes it, and the lidar scans the room to locate the destination; 2. The hydraulic support feet descend, lifting the bed 5 cm off the ground, reducing the load on the drive wheels, while the pressure sensor grid verifies that the patient's position is stable; 3. The four-wheel differential drive moves along the planned path and monitors in real time: the encoder feeds back the posture to correct the path deviation; the ultrasonic wave monitors obstacles within 10 cm to effectively ensure the emergency stop response time; 4. After arriving at the destination, if the destination is the location of the wheelchair, the lifting component will automatically descend to the height corresponding to the wheelchair seat cushion.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
