Description

Technical Field

[0001] This invention belongs to the field of nursing bed technology, specifically, it relates to a multifunctional integrated nursing bed for all scenarios. Background Technology

[0002] In existing technologies, nursing beds can achieve functions such as backrest lifting and leg bending, and are mainly used to assist disabled and semi-disabled people in carrying out daily activities. However, in actual care scenarios, there are still inconveniences. Specifically, when the person being cared for needs to leave the bed to move, such as to use the toilet, bathe, or engage in outdoor activities, caregivers must move them from the bed to a wheelchair. This transfer process usually requires multiple caregivers to work together to carry, lift, and move the person being cared for, which is not only extremely inconvenient but also extremely labor-intensive. At the same time, there are serious safety hazards such as the person being cared for falling, bumping, or tubes becoming detached during the transfer process. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-functional integrated nursing bed for all scenarios. By reusing the functions of functional components such as the legrests between the bed and wheelchair states, the wheelchair does not need to be equipped with an additional seat and backrest. With quick assembly and disassembly and detachable armrests, it achieves truly convenient use in all scenarios.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A multi-functional integrated nursing bed for all scenarios, comprising: The main bed frame is equipped with support legs at the bottom; The auxiliary bed frame is detachably installed at the rear of the main bed frame. It is equipped with wheels at the bottom and a rotating pedal on the lower side. In the combined state, the auxiliary bed frame and the main bed frame together form the main body of the nursing bed. In the disassembled state, the auxiliary bed frame can be used as an independent wheelchair. The first support frame is arranged along the length of the main bed frame and has a first fixed main frame and a first rotating frame rotatably connected to one end of the first fixed main frame; a buttock bed board is provided on the first fixed main frame and a back bed board is provided on the first rotating frame. The second support frame is arranged along the width direction of the sub-bed frame, and has a second fixed main frame and a second rotating frame rotatably connected to one end of the second fixed main frame; a fixed plate is provided on the second fixed main frame, and a movable plate is provided on the second rotating frame, and the fixed plate and the movable plate are arranged side by side to form a leg bed board; in the wheelchair state, the movable plate rotates upward relative to the second fixed main frame to form a backrest, and the fixed plate forms a seat board; A bed foot rail is installed at the end of the sub-bed frame. Its first side is connected to the main bed frame, and its opposite second side forms a passage between the sub-bed frame and the main bed frame for the sub-bed frame to be moved out. A guardrail, detachably installed between the second side of the foot rail and the main bed frame, is used to enclose the passageway; The adjustment mechanism includes a backrest adjustment module that drives the first rotating frame to rotate and a movable plate adjustment module that drives the second rotating frame to rotate.

[0005] Preferably, vertical rods integrally formed with the second support frame are provided on both sides of one end of the second support frame, and a bottom frame is connected between the two vertical rods. The lower end of the vertical rods and both sides of the rear end of the bottom frame are provided with the traveling wheels.

[0006] Preferably, it also includes detachable handrails, and the two sides of the second fixed main frame are provided with plug-in parts for connecting to the handrails, and the fixed plate is provided with clearance space parts corresponding to the plug-in parts.

[0007] Preferably, one end of the rotating pedal is rotatably connected to the two vertical rods.

[0008] Preferably, it further includes a locking mechanism for locking and securing the sub-bed frame to the main bed frame in the combined state.

[0009] Preferably, the first side of the foot rail is connected to the main bed frame via a connecting plate.

[0010] Preferably, the locking mechanism includes an electromagnet disposed on the connecting plate and an adsorption plate disposed at the end of the second bearing frame and used in conjunction with the electromagnet.

[0011] Preferably, the main bed frame and the second side of the footboard are provided with interlocking protrusions, and the two sides of the guardrail are provided with interlocking grooves that cooperate with the interlocking protrusions.

[0012] Preferably, the movable plate adjustment module includes an adjustment screw, a screw nut disposed on the second fixed main frame, a hand crank handle disposed at one end of the adjustment screw, and one end of the adjustment screw is rotatably connected to the second rotating frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention combines the main bed frame with a secondary bed frame that can be independently converted into a wheelchair, achieving an integrated design of nursing bed and wheelchair. When the person being cared for needs to move, no manual lifting is required; the secondary bed frame can be separated and used directly as a wheelchair. This not only fundamentally eliminates safety hazards during the transfer process and reduces the labor intensity of caregivers, but also enriches the applicable scenarios of the nursing bed.

[0014] This invention creatively reuses the fixed and movable plates of the leg bed board as a seat and backrest respectively in wheelchair mode, eliminating the need for additional seat cushions and backrest components in the sub-bed frame. While achieving the full functionality of a wheelchair, it greatly simplifies the overall structure and ensures a compact bed form.

[0015] In this invention, the first and second load-bearing frames, the backrest adjustment module and the movable plate adjustment module all adopt the same structural design. The only difference is in the arrangement direction due to functional requirements. The connection method of the two sets of frames and the drive is completely consistent, which greatly reduces the types of parts, reduces manufacturing costs, and facilitates assembly and maintenance.

[0026] To enable those skilled in the art to have a clearer understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described below are merely for illustrative purposes and to facilitate understanding. The technical solutions provided by the present invention are not limited to those provided in the following embodiments, nor should they limit the scope of protection of the present invention. Example

[0027] like Figures 1-9 As shown, this embodiment provides a multi-functional integrated nursing bed for all scenarios, which mainly includes a main bed frame 1 and a secondary bed frame 3. The main bed frame 1 is a fixed part, made of rectangular steel tubes or aluminum alloy profiles welded together. Four support legs 2 are fixed to the four corners of its bottom surface by bolts or directly welded. The bottom ends of the support legs 2 can be fitted with anti-slip pads. The two sides of the main bed frame 1 are side rails, which can be used as storage panels for placing food. The secondary bed frame 3 serves as a detachable wheelchair body, and its skeleton structure is also made of welded metal tubes. In the assembled state, the secondary bed frame 3 is detachably installed at the rear of the main bed frame 1, and the two are connected end to end. The bed board laid on them together forms a complete bed surface.

[0028] The bottom of the auxiliary bed frame 3 is equipped with four wheels 4, two of which are omnidirectional wheels at the front and two of which are fixed wheels with brakes at the rear. A rotating pedal 5 is rotatably connected to the lower side of the auxiliary bed frame 3. The rotating pedal 5 is used to support the user's feet in wheelchair mode and can be flipped up and stored at the bottom when in nursing bed mode.

[0029] In this embodiment, a first supporting frame 6 is provided on the main bed frame 1 along its length. The first supporting frame 6 consists of a first fixed main frame 7 and a first rotating frame 8. The first fixed main frame 7 is fixedly connected to the main bed frame 1 by bolts. One end of the first rotating frame 8 is hinged to one end of the first fixed main frame 7 by a horizontal pin, allowing the first rotating frame 8 to rotate upward around the pin. The buttocks bed board 9 and the back bed board 10 are both made of wood laminate or a combination of wood laminate and flexible padding (such as sponge pad). The buttocks bed board 9 is fixed to the first fixed main frame 7 and is provided with a toilet bowl opening, which can be used for defecation without the patient getting out of bed. The back bed board 10 is fixed to the first rotating frame 8 and moves with it.

[0030] In this embodiment, a second support frame 11 is provided on the sub-bed frame 3 along its width direction. It should be noted that the second support frame 11 and the first support frame 6 are substantially the same in mechanical structure, both consisting of a fixed main frame and a rotating frame hinged together, differing only in their arrangement direction on the bed. Specifically, the second support frame 11 consists of a second fixed main frame 12 and a second rotating frame 13. The second fixed main frame 12 is fixed to the sub-bed frame 3, and one end of the second rotating frame 13 is hinged to the second fixed main frame 12. A fixed plate 14 is fixed on the second fixed main frame 12, and a movable plate 15 is fixed on the second rotating frame 13. The two are arranged side by side, and together in the combined state, they form a leg bed board 16 that supports the user's thighs and calves. The leg bed board 16 is also made of wood laminate or a combination of wood laminate and a flexible padding layer (such as a sponge pad).

[0031] To enable the secondary bed frame 3 to be converted into a complete wheelchair after disassembly, the conversion mechanism of the present invention is as follows: when the secondary bed frame 3 is separated from the main bed frame 1 and used as a wheelchair independently, the second rotating frame 13 is driven to rotate upward around its hinge axis by the movable plate adjustment module, thereby causing the movable plate 15 to stand up and form the backrest of the wheelchair; while the fixed plate 14, which remains horizontal, naturally becomes the seat for the user to sit on.

[0032] In this embodiment, the movable plate adjustment module adopts an existing mature hand-cranked screw and nut structure, as shown in the following example: It includes an adjusting screw 30, the middle threaded section of which is screwed into a screw nut 31. The screw nut 31 is fixedly mounted on the second fixed main frame 12. One end (upper end) of the adjusting screw 30 is rotatably connected to the crossbeam of the second rotating frame 13 through a universal joint or ball joint, and the other end (lower end) is fixed with a hand crank 32. During operation, the caregiver cranks the hand crank 32, and the adjusting screw 30 rotates within the screw nut 31 and generates axial displacement, thereby pushing or pulling the second rotating frame 13 to make it rotate smoothly relative to the second fixed main frame 12. The screw and nut mechanism has a self-locking characteristic and can stop at any angle, ensuring that the backrest angle is adjustable and safe to use.

[0033] The backrest adjustment module and the movable board adjustment module have the same structure. One end of the adjustment screw is connected to the first rotating frame 8, and the screw nut seat is located on the first fixed main frame 7. By shaking the handle, the first rotating frame 8 is driven to flip upward, realizing the backrest lifting function, which will not be described in detail here.

[0034] It should be understood that although the drive mechanism in this embodiment is a hand-cranked screw and nut mechanism, in order to achieve electrification, the hand crank handle 32 can be replaced with a geared motor, that is, the motor output shaft drives the adjusting screw 30 to rotate. This is a simple replacement based on the core inventive concept of this invention and should be considered to fall within the protection scope of this invention.

[0035] Two vertical rods 20 are integrally formed or welded on both sides of the front end of the auxiliary bed frame 3 (i.e. the side closer to the legs after conversion into a wheelchair). A horizontal bottom frame 21 is welded between the two vertical rods 20 to form a stable support structure.

[0036] The bottom of the vertical bar 20 and both sides of the rear end of the bottom frame 21 are equipped with walking wheels 4. One end of the rotating pedal 5 is rotatably connected to the inner side of the lower part of the vertical bar 20 on both sides through a hinge shaft. When the sub-bed frame 3 is in the state of a nursing bed, the rotating pedal 5 flips up and folds up. When the sub-bed frame 3 is converted into a wheelchair, the rotating pedal 5 flips down and unfolds, allowing the user to step on it.

[0037] To provide lateral support and protection, this nursing bed is also equipped with detachable armrests 22. Specifically, hollow insertion parts 23 are welded to both sides of the second fixed main frame 12. The lower end of the vertical rod of the armrest 22 can be inserted into the insertion part 23. To provide space for the insertion part 23, clearance spaces 24, i.e., side notches, are provided on both sides of the fixed plate 14. To better facilitate the use of wheelchairs, this embodiment also provides push handles 33 on both sides of the back of the second rotating frame 13 for easy pushing of the wheelchair after the auxiliary bed frame is converted into a wheelchair.

[0038] The secondary bed frame 3 is provided with a foot rail 17 at the end away from the main bed frame 1 (i.e., the tail end). The foot rail 17 includes a footboard 34 that is installed on the ground and a guardrail 35 at the upper end of the footboard 35. The first side of the footboard 34 (right side in the figure) is connected to the end of the frame of the main bed frame 1 through a connecting plate 25. Specifically, one end of the connecting plate 25 is fixed to the footboard 34 with bolts, and the other end is connected to the main bed frame 1 with bolts.

[0039] To achieve rigid locking in the combined state, this embodiment employs an electromagnetic locking mechanism. An electromagnet 26 is embedded in the connecting plate 25, and an adsorption plate 27 is fixed at the corresponding position at the end of the second supporting frame 11 near the connecting plate 25. When the secondary bed frame 3 is pushed into place, the electromagnet 26 is energized, generating a magnetic force that firmly attracts the adsorption plate 27, thereby locking the secondary bed frame 3 to the main bed frame 1. After de-energizing, the magnetic force disappears, and the secondary bed frame 3 can be separated. It should be noted that the electromagnetic locking method used in this embodiment can also be replaced by mechanical locking methods such as manual pins or buckles. All such simple substitutions based on the core inventive concept of this invention should be considered to fall within the protection scope of this invention.

[0040] There is a certain gap between the second side of the foot rail 17 (left side in the figure) and the edge of the main bed frame 1. This gap is the passage 18 for the secondary bed frame 3 to be moved out laterally. The passage 18 is normally closed by a guard plate 19. For easy assembly and disassembly, a vertical insertion protrusion 28 is provided on the side of the main bed frame 1 and the second side of the foot rail 17. The two sides of the guard plate 19 are provided with corresponding insertion slots 29. When in use, the insertion slots 29 of the guard plate 19 are aligned with the insertion protrusions 28 and inserted from top to bottom to close the passage. When the secondary bed frame 3 needs to be moved out, the guard plate 19 is pulled up and pulled out.

[0041] The process of using this invention is as follows: When the nursing bed is in its normal state, the auxiliary bed frame 3 is combined with the main bed frame 1, the guard plate 19 closes the passage 18, and the electromagnet 26 is energized and locked, making the entire bed stable; the caregiver can adjust the angle of the back bed board 10 through the back bed board adjustment module to get up; and the leg support is obtained through the leg bed board 16.

[0042] When converting to a wheelchair, first de-energize the electromagnet 26, pull out the guard plate 19 upwards, and then push the auxiliary bed frame 3 out from the side of the passage 18, completely separating it from the main bed frame 1; then drive the movable plate 15 upwards to a suitable angle to form a backrest by cranking the handle 32, and then unfold the rotating footboard 5 downwards. At this point, the auxiliary bed frame 3 has been completely transformed into a wheelchair, and the user can move freely in it.

[0043] The electrical components in the nursing bed are battery-powered, comprising two independently powered batteries: a main bed frame battery and a secondary bed frame battery. The main bed frame battery is fixedly installed inside the bottom or side frame of the main bed frame 1, supplying power to the electrical components on the main bed frame 1. The secondary bed frame battery is fixedly installed on the bottom frame 21 of the secondary bed frame 3, supplying power to the electrical components on the secondary bed frame 3, including but not limited to the electromagnet 26 and the geared motor of the movable plate adjustment module. Preferably, both batteries are rechargeable and can be charged via wired or wireless means. The separate power supply design ensures that the secondary bed frame 3, when detached from the main bed frame 1 and used independently as a wheelchair, still has a complete power supply, and all electrical components can operate normally without being affected by the separation.

[0044] The above description represents the preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements without departing from the design principles and technical solutions of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
