Description

Technical Field

[0001] This utility model relates to the field of nursing bed technology, specifically a smart home-controlled multifunctional nursing bed. Background Technology

[0002] With the aging population and increasing demand for home care, addressing issues such as positioning, safety, and improved care efficiency for patients with limited mobility has become a key focus of medical device research and development. Smart home care beds, by integrating automation functions, can effectively reduce the burden on caregivers, and are particularly suitable for scenarios involving prolonged bed rest or postoperative rehabilitation.

[0003] While existing nursing beds have achieved basic functions such as electric turning and guardrail height adjustment, they generally suffer from disjointed operation and safety vulnerabilities: when the bed board is tilted to assist in turning the patient, the guardrail height needs to be manually adjusted to match the change in body position; failure to adjust in time can easily lead to the patient slipping. Furthermore, in daily care, if temporary adjustments to the guardrail height are needed (such as when transferring patients or cleaning), traditional manual adjustment requires repeated operation of the locking mechanism, a cumbersome process prone to accidental activation and potential safety hazards. The root cause of these problems lies in the fact that existing technology has not integrated the turning drive, guardrail linkage, and manual release mechanism into an efficient interactive system, resulting in safety blind spots and operational redundancy in the nursing process. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a smart home-controlled multifunctional nursing bed to solve the technical problem that existing nursing beds lack an efficient linkage mechanism between the height adjustment of the guardrail and the tilting action of the bed board when assisting patients to turn over, which leads to the risk of patients slipping due to the lag in guardrail adjustment or untimely manual operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a smart home control multifunctional nursing bed, including a nursing bed frame, a liftable support base at the bottom of the nursing bed frame, an adjustable backrest on the nursing bed frame, a control panel on the nursing bed frame, a nursing bed board for nursing care on the nursing bed frame, and a shelf for placing items that is slidably arranged on the nursing bed frame.

[0006] The nursing bed includes a first bed board and two adjustable second bed boards, which are symmetrically arranged on both sides of the first bed board. The nursing bed is equipped with guardrails whose height can be adjusted as the second bed boards are tilted.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please refer to Example 1 Figures 1-5This utility model provides a technical solution: a smart home-controlled multifunctional nursing bed, including a nursing bed body 1, a liftable support base 11 at the bottom of the nursing bed body 1, an adjustable backrest 12 on the nursing bed body 1, a control panel 13 on the nursing bed body 1, a nursing bed board 2 for nursing care on the nursing bed body 1, and a shelf 14 for placing items that slides on the nursing bed body 1. The integration of the liftable support base 11, the adjustable backrest 12, and the control panel 13 forms a multi-dimensional adjustment base to meet different body position needs; the sliding design of the shelf 14 facilitates quick access to nursing supplies, improving operational convenience.

[0022] The nursing bed 2 includes a first bed board 21 and two adjustable second bed boards 22, which are symmetrically arranged on both sides of the first bed board 21. The nursing bed frame 1 is equipped with guardrails 23 whose height adjusts with the tilt of the second bed boards 22. The symmetrical distribution of the second bed boards 22 and their adjustable angle accommodate the patient's turning needs; the height of the guardrails 23 automatically changes with the tilt of the bed boards, forming a dynamic anti-fall protection and reducing nursing risks.

[0023] Furthermore, the nursing bed frame 1 is equipped with two mounting plates 31, each mounting plate 31 having a second mounting bracket 36. A first connecting plate 37 rotates within the second mounting bracket 36, and a second connecting plate 38 is fixed to the top of the first connecting plate 37. The top of the second connecting plate 38 is fixedly connected to the bottom of the second bed board 22. When the first connecting plate 37 rotates within the second mounting bracket 36, it drives the second bed board 22 on one side to rotate. The rotation of the first connecting plate 37 and the second connecting plate 38 enables precise tilting of the second bed board 22, replacing manual assistance in turning over and reducing the need for nursing manpower.

[0024] Furthermore, a first mounting bracket 32 ​​is provided on the mounting plate 31. A threaded rod 33 rotates within the first mounting bracket 32. A movable block 34 is externally threaded onto the threaded rod 33. A connecting bracket 35 is rotatably connected to the movable block 34. The top end of the connecting bracket 35 is rotatably connected to the first connecting plate 37. A connecting groove is provided on the threaded rod 33 for transmission to the output shaft of the power supply. The threaded rod 33 is driven to rotate by a motor, which drives the movable block 34 to move linearly. This movement is converted into tilting power for the second bed board 22 via the connecting bracket 35, thereby achieving automated control of the turning action.

[0025] Furthermore, a limiting groove is provided on the mounting plate 31, and the movable block 34 is slidably disposed within the limiting groove. The limiting groove constrains the movement trajectory of the movable block 34, preventing transmission deviation, ensuring smooth adjustment of the second bed plate 22, and improving the reliability of equipment operation.

[0026] Please refer to Example 2 Figures 6-7Furthermore, in conjunction with Embodiment 1, it is further found that both sides of the nursing bed body 1 are provided with mounting frames 41, and adjusting frames 42 are slidably disposed in the mounting frames 41. The top end of the adjusting frame 42 is fixedly connected to the bottom end of the guardrail 23. A connecting rack 43 is fixedly fixed to the inner wall of the adjusting frame 42. The adjusting frame 42 and the mounting frame 41 slide together to provide a vertical lifting channel for the guardrail 23; the connecting rack 43 serves as a transmission medium to realize the linkage control of the height of the guardrail 23 and the tilt of the second bed board 22.

[0027] Furthermore, a connecting rod 44 is fixed to one end of each threaded rod 33. The connecting rod 44 passes through the mounting frame 41 and is set inside an adjusting frame 42. A gear 45 is slidably mounted on the outside of the connecting rod 44, and the gear 45 meshes with the connecting rack 43. The connecting rod 44 transmits the rotational power of the threaded rod 33 to the gear 45. Through the meshing of the gear 45 and the connecting rack 43, the adjusting frame 42 is driven to slide, so as to realize the automatic synchronous adjustment of the height of the guardrail 23 as the second bed board 22 tilts.

[0028] Furthermore, a connecting plate 46 is fixedly attached to the outside of the connecting rod 44. A first spring 47 is provided between the connecting plate 46 and the gear 45, and the first spring 47 is sleeved on the outside of the connecting rod 44. A push tube 48 is slidably arranged in the mounting frame 41, and one end of the push tube 48 is fixedly connected to the outside of the first spring 47. When the push tube 48 slides, the gear 45 slides outside the connecting rod 44, the first spring 47 is in a compressed state, and the gear 45 is disengaged from the connecting rack 43. The first spring 47 and the push tube 48 constitute a manual release mechanism. Pressing the push tube 48 can release the engagement between the gear 45 and the connecting rack 43, allowing the guardrail 23 to be adjusted manually and independently, thus meeting the dual requirements of automatic linkage and flexible adjustment.

[0029] The workflow for controlling the multi-functional nursing bed via smart home technology is as follows: After the patient's turning over is activated via the control panel 13, the motor output shaft engages with the connecting groove of the threaded rod 33 on the target side, driving the threaded rod 33 to rotate within the first mounting frame 32. The movable block 34 slides along the limiting groove of the mounting plate 31, pulling the first connecting plate 37 to rotate within the second mounting frame 36 via the connecting frame 35. Simultaneously, the second connecting plate 38 at the top of the first connecting plate 37 drives the corresponding second bed board 22 to tilt upward, thus enabling the patient to turn over. During this process, the connecting rod 44 at the end of the threaded rod 33 drives the gear 45 to rotate. The gear 45 meshes with the connecting rack 43 within the adjusting frame 42, pushing the other adjusting frame 42 to slide upward along the mounting frame 41, causing the corresponding guardrail 23 to automatically rise, forming a fall protection system.

[0030] When the automatic adjustment of the guardrail 23 is not required, the user can press the push tube 48 to compress the first spring 47, causing the gear 45 to disengage from the connecting rack 43. At this time, the guardrail 23 can be manually pulled to slide within the mounting frame 41 via the adjustment frame 42 to adjust to a suitable height. For daily use, a massage cushion can be added to the nursing bed board 2, activated via the control panel 13, providing auxiliary nursing functions. When items need to be placed, the storage board 14 can be directly pulled out for use, and the adjustable support seat 11 and adjustable backrest 12 can meet different nursing needs. The entire process is centrally controlled via the control panel 13, achieving intelligent integration of turning care, guardrail linkage, massage assistance, and storage functions, improving nursing safety and operational convenience.
