Description

Technical Field

[0001] This utility model relates to the field of electric nursing bed technology, specifically to a lifting device for an intelligent electric nursing bed. Background Technology

[0002] An electric nursing bed is a specialized bed that uses an electric device to adjust the height, angle, and posture of the bed surface. It is widely used in hospitals, nursing homes, and home care settings to improve patient comfort and the work efficiency of caregivers.

[0003] The existing technology has the following defects or problems: The existing technology disclosed in CN209790230U discloses a lifting device for an intelligent electric nursing bed. The base plate is provided with a lifting adjustment rod, a lifting adjustment cylinder, a locking device, a base, and a connector that are fixedly connected to the base plate. The top of the lifting adjustment rod is fixedly connected to the bed body. The lifting adjustment rod is sleeved inside the lifting adjustment cylinder. The connector is set on the outer wall of the lifting adjustment cylinder. The locking device includes a rotating shaft, a locking part, and a handle part. The locking device is fixedly installed on the connector and can rotate. The end of the locking part can pass through the through hole provided on the connector and contact the tooth groove. A cylinder is provided at the lower part of the lifting adjustment rod. Front guardrails and rear guardrails are provided on the front and rear sides of the bed body, respectively. Side guardrails and handles are provided on each side of the bed body. A controller is provided on the side of the bed body.

[0004] During use, the above-mentioned device achieves locking through the engagement of the locking part with the tooth groove. The locking part has a wedge-shaped structure, with the side of the locking part corresponding to the bottom of the lifting adjustment rod being an upward slope, and the side corresponding to the top of the lifting adjustment rod being a horizontal plane or an upward slope. The end of the locking part can pass through the through hole provided on the connector and contact the tooth groove, thereby achieving locking through the engagement of the locking part with the tooth groove. When unlocking, the interaction between the slope on the locking part and the lifting adjustment rod achieves unlocking, giving the nursing bed a locking function and improving the safety and stability of the nursing bed.

[0005] The lifting device of the aforementioned intelligent electric nursing bed has an overly rudimentary structure and lacks stability, posing certain safety hazards to patients during use. Furthermore, most nursing beds include a small table for eating, which caregivers place on the bed for convenience. However, the table is prone to wobbling or shifting due to collisions, leading to food spillage. Additionally, the bed cannot be adjusted to suit individual needs based on patient size, illness, or recovery progress, and it cannot accommodate various eating postures.

[0006] Therefore, a lifting device for an intelligent electric nursing bed is proposed to solve the problems mentioned above. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a lifting device for an intelligent electric nursing bed. This device solves the problem of insufficient stability, which poses certain safety hazards to patients during use. Furthermore, most nursing beds are equipped with a small table for eating, which nursing staff need to place on the bed to provide convenience for patients to eat. However, the table is prone to shaking or shifting due to collisions, resulting in food spillage. In addition, different patients have different body shapes, diseases, or recovery conditions, making it inconvenient to adjust the device according to individual needs and unable to accommodate various different eating postures.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a bed frame is included, with a first cylinder fixedly connected to the bottom of the bed frame, a first triangular rod fixedly connected to the output end of the first cylinder, a first connecting rod rotatably connected to the other end of the first triangular rod, a rotating plate rotatably connected to the other end of the first connecting rod, a rotating rod rotatably connected to the other end of the rotating plate, a support rod rotatably connected to the other end of the rotating rod, and a headboard rotatably connected to the bottom of the support rod. When the first cylinder extends or retracts, it pushes the first triangular rod to rotate around the connection point, thereby driving the first connecting rod to push and pull the rotating plate. The rotating plate then changes the tilt angle of the support rod through the rotating rod, ultimately realizing the lifting or flipping of the headboard.

[0009] A second cylinder is fixedly connected to the bottom of the bed frame. The output end of the second cylinder is rotatably connected to a second triangular rod. The other end of the second triangular rod is rotatably connected to a second connecting rod. The other end of the second connecting rod is rotatably connected to a tripod. A support frame is rotatably connected to the upper surface of the tripod. A bed end frame is fixedly connected to the upper surface of the support frame. When the second cylinder extends or retracts, it drives the second triangular rod to rotate, which in turn drives the tripod to move up and down via the second connecting rod. The tripod further supports and pushes the support frame, enabling the bed end frame to complete its lifting and lowering motion.

[0010] Preferably, at least two mounting rods are symmetrically fixedly connected to the upper surface of the bed frame. Each mounting rod has a symmetrically formed movable groove inside. A first spring is fixedly connected inside the movable groove. A pull rod is fixedly connected to the top of the first spring. A first concave block is fixedly connected to the outer surface of the pull rod. A first movable rod is rotatably connected inside the first concave block. The pull rod drives the first concave block to move upward, causing the first concave block to drive the first movable rod to rotate.

[0011] Preferably, a second spring is fixedly connected inside the movable groove, and a locking rod is fixedly connected to the other end of the second spring. A second concave block is fixedly connected to the upper surface of the locking rod. The interior of the second concave block is rotatably connected to the other end of the first movable rod. The second concave block and the locking rod slide out of the interior of the mounting plate. At this time, the nursing staff can remove the mounting plate and the table from the nursing bed. The resetting effect of the first spring and the second spring allows the pull rod and the locking rod to quickly reset.

[0012] Preferably, an installation plate is inserted inside the installation rod, and the two sides of the installation plate are engaged with the locking rod.

[0013] Preferably, a motor is fixedly connected to the outer surface of the mounting plate, a bidirectional lead screw is fixedly connected to the output end of the motor, a movable plate is symmetrically threaded to the outer surface of the bidirectional lead screw, a first connecting block is fixedly connected to the upper surface of the movable plate, and a second movable rod is rotatably connected inside the first connecting block. The motor drives the bidirectional lead screw to rotate, causing the symmetrical movable plates to slide in opposite directions along the limiting rod. The movable plates drive the second movable rod to rotate through the first connecting block.

[0014] Preferably, a fixing plate is fixedly connected to the inner side of the mounting plate, and a support plate is fixedly connected to the other side of the fixing plate. A telescopic rod is fixedly connected to the upper surface of the support plate, and a table body is fixedly connected to the output end of the telescopic rod. A second connecting block is symmetrically fixedly connected to the lower surface of the table body. The interior of the second connecting block is rotatably connected to the other end of the second movable rod. The second movable rod rotates in the second connecting block, and together with the extension and retraction of the telescopic rod, it pushes the table body to rise and fall smoothly.

[0015] Preferably, a limiting rod is fixedly connected between the mounting plates, the outer surface of the limiting rod is slidably connected to the movable plate, the limiting rod is fixedly connected to the support plate, and the interior of the support plate is rotatably connected to the bidirectional lead screw.

[0016] Compared with the prior art, this utility model provides a lifting device for an intelligent electric nursing bed, which has the following beneficial effects:

[0017] 1. By setting two cylinders, which drive multiple connecting rods to operate, the support rods and support frame drive the headboard and footboard to achieve lifting and lowering movements. This helps nursing staff adjust the bed height, avoids back injuries caused by frequent bending or moving patients, improves work efficiency, and makes it easier to perform cleaning, dressing changes, examinations and other operations on patients, reducing patient discomfort.

[0018] 2. By incorporating a mounting rod, the table used for patient meals can be fixed to the bed and quickly disassembled, preventing the table from shifting during use, thus enhancing the usability and convenience of the nursing bed.

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please see Figure 1 - Figure 4 The lifting device of an intelligent electric nursing bed in this embodiment includes a bed frame 1. A first cylinder 2 is fixedly connected to the bottom of the bed frame 1. A first triangular rod 3 is fixedly connected to the output end of the first cylinder 2. A first connecting rod 4 is rotatably connected to the other end of the first triangular rod 3. A rotating plate 5 is rotatably connected to the other end of the first connecting rod 4. A rotating rod 6 is rotatably connected to the other end of the rotating plate 5. A support rod 7 is rotatably connected to the other end of the rotating rod 6. A headboard 35 is rotatably connected to the bottom of the support rod 7.

[0030] A second cylinder 8 is fixedly connected to the bottom of the bed frame 1. A second triangular rod 9 is rotatably connected to the output end of the second cylinder 8. A second connecting rod 10 is rotatably connected to the other end of the second triangular rod 9. A triangular frame 11 is rotatably connected to the other end of the second connecting rod 10. A support frame 12 is rotatably connected to the upper surface of the triangular frame 11. A bed footrest 13 is fixedly connected to the upper surface of the support frame 12.

[0031] When the first cylinder 2 extends or retracts, it pushes the first triangular rod 3 to rotate around the connection point, which in turn drives the first connecting rod 4 to push and pull the rotating plate 5. The rotating plate 5 then changes the tilt angle of the support rod 7 through the rotating rod 6, ultimately realizing the lifting or flipping of the headboard 35.

[0032] At this point, the second cylinder 8 can be activated. When the second cylinder 8 extends or retracts, it drives the second triangular rod 9 to rotate, which in turn drives the triangular frame 11 to move up and down via the second connecting rod 10. The triangular frame 11 further supports and pushes the support frame 12, enabling the bed end frame 13 to complete the lifting and lowering action, thereby facilitating the adjustment of the bed height by nursing staff.

[0033] At least two mounting rods 14 are symmetrically fixedly connected to the upper surface of the bed frame 1. Each mounting rod 14 has a movable groove 15 symmetrically opened inside. A first spring 16 is fixedly connected inside the movable groove 15. A pull rod 17 is fixedly connected to the top of the first spring 16. A first concave block 18 is fixedly connected to the outer surface of the pull rod 17. A first movable rod 19 is rotatably connected inside the first concave block 18. A second spring 20 is fixedly connected inside the movable groove 15. A locking rod 21 is fixedly connected to the other end of the second spring 20. A second concave block 22 is fixedly connected to the upper surface of the locking rod 21. The interior of the second concave block 22 is rotatably connected to the other end of the first movable rod 19. A mounting plate 23 is inserted inside the mounting rod 14. The two sides of the mounting plate 23 are interlocked with the locking rod 21.

[0034] A motor 24 is fixedly connected to the outer surface of the mounting plate 23. A bidirectional lead screw 25 is fixedly connected to the output end of the motor 24. A movable plate 26 is symmetrically threaded to the outer surface of the bidirectional lead screw 25. A first connecting block 27 is fixedly connected to the upper surface of the movable plate 26. A second movable rod 28 is rotatably connected to the inside of the first connecting block 27. A fixed plate 29 is fixedly connected to the inner side of the mounting plate 23. A support plate 30 is fixedly connected to the other side of the fixed plate 29. A telescopic rod 31 is fixedly connected to the upper surface of the support plate 30. A table body 32 is fixedly connected to the output end of the telescopic rod 31. A second connecting block 33 is symmetrically fixedly connected to the lower surface of the table body 32. The inside of the second connecting block 33 is rotatably connected to the other end of the second movable rod 28. A limit rod 34 is fixedly connected between the mounting plates 23. The outer surface of the limit rod 34 is slidably connected to the movable plate 26. The limit rod 34 is fixedly connected to the support plate 30. The inside of the support plate 30 is rotatably connected to the bidirectional lead screw 25.

[0035] When the table body 32 needs to be installed, the mounting plate 23 can be directly inserted into the mounting rod 14, so that the mounting plate 23 abuts against the locking rod 21. The locking rod 21 retracts into the movable groove 15 through the second spring 20 inside the movable groove 15, and then quickly rebounds into the interior of the mounting plate 23 to complete the installation of the table body 32. After use, the caregiver can pull the pull rod 17, which drives the first concave block 18 to move upward, so that the first concave block 18 drives the first movable rod 19 to rotate inside the second concave block 22, thereby causing the second concave block 22 and the locking rod 21 to slide out of the interior of the mounting plate 23. At this time, the caregiver can remove the mounting plate 23 and the table body 32 from the nursing bed. The first spring 16 and the second spring 20 reset the pull rod 17 and the locking rod 21 quickly.

[0036] Motor 24 drives bidirectional lead screw 25 to rotate, causing symmetrical movable plates 26 to slide in opposite directions along limit rod 34. Movable plates 26 drive second movable rod 28 to rotate in second connecting block 33 through first connecting block 27. Together with the extension and retraction of telescopic rod 31, they push table body 32 to rise and fall smoothly.

[0037] The working principle of the above embodiment is as follows: During use, the first cylinder 2 is activated. When the first cylinder 2 extends or retracts, it pushes the first triangular rod 3 to rotate around the connection point, thereby driving the first connecting rod 4 to push and pull the rotating plate 5. The rotating plate 5 then changes the tilt angle of the support rod 7 via the rotating rod 6, ultimately achieving the lifting or tilting of the headboard 35. Simultaneously, the second cylinder 8 can be activated. When the second cylinder 8 extends or retracts, it drives the second triangular rod 9 to rotate, which in turn drives the triangular frame 11 to move up and down via the second connecting rod 10. The triangular frame 11 further supports and pushes the support frame 12, enabling the footboard 13 to complete the lifting and lowering action. This facilitates the adjustment of the bed height by nursing staff, avoids back injuries caused by frequent bending or moving of patients, improves work efficiency, and makes it easier to perform cleaning, dressing changes, and examinations for patients, reducing patient discomfort.

[0038] When it is necessary to install the table body 32, the mounting plate 23 can be directly inserted into the mounting rod 14, so that the mounting plate 23 abuts against the locking rod 21. The locking rod 21 retracts into the movable groove 15 through the second spring 20 inside the movable groove 15, and then quickly rebounds into the interior of the mounting plate 23 to complete the installation of the table body 32.

[0039] When the height of the table 32 needs to be adjusted, the motor 24 is started, which drives the bidirectional lead screw 25 to rotate, causing the symmetrical movable plate 26 to slide in opposite directions along the limit rod 34. The movable plate 26 drives the second movable rod 28 to rotate in the second connecting block 33 through the first connecting block 27. Together with the extension and retraction of the telescopic rod 31, the table 32 is pushed up and down smoothly to meet the needs of patients for dining, reading and other activities.

[0040] After use, the nurse can pull the lever 17, which will move the first recess 18 upward. This will cause the first recess 18 to rotate the first movable rod 19 inside the second recess 22, thereby causing the second recess 22 and the locking rod 21 to slide out of the mounting plate 23. At this time, the nurse can remove the mounting plate 23 and the table 32 from the nursing bed. The lever 17 and the locking rod 21 will quickly return to their original positions due to the reset effect of the first spring 16 and the second spring 20.

[0041] The entire device uses a multi-link mechanism driven by a first cylinder 2 and a second cylinder 8 to achieve bed lifting and posture adjustment. At the same time, it uses a locking structure of a first spring 16 and a second spring 20 and a transmission of a motor 24 and a two-way lead screw 25 to complete the installation and adjustment of auxiliary components, thus realizing automated nursing functions. The first cylinder 2 and the second cylinder 8 are fixed by the bed frame 1, and the support plate 30 is fixed by the fixing plate 29.

[0042] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
