[0035] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0036] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0037] Reference Figures 1-5 As shown, an exemplary embodiment of the present disclosure discloses a nursing bed including a bed frame 1 and a turning mechanism 4. The bed frame 1 supports a central frame 2 and two side frames 3. The two side frames 3 are respectively disposed on both sides of the central frame 2 and are both hinged to the central frame 2. The central frame 2 is rotatably disposed on the centerline of the bed frame 1 via a pivot. The turning mechanism 4 is connected to the central frame 2 and is used to drive the central frame 2 to rotate around the pivot and cause one of the side frames 3 to fold upward toward the bed frame 1.

[0038] In this embodiment, the two side frames 3 are respectively hinged to both sides of the central frame 2, allowing the side frames 3 to rotate flexibly relative to the central frame 2 at a certain angle. The central frame 2 is rotatably mounted on the centerline of the bed frame 1 via a pivot. The pivot is preferably positioned such that the central frame 2 can rotate around its own axis of symmetry, thereby driving the side frames 3 hinged to it to move. The turning mechanism 4 is connected to the central frame 2, and its main function is to drive the central frame 2 to rotate around its pivot. When the turning mechanism 4 is activated, the central frame 2 rotates around its pivot, thereby causing one of the side frames 3 to fold upwards towards the bed frame 1. Understandably, since the central frame 2 and the two side frames 3 are all supported on the bed frame 1 under normal conditions, the bed frame 1 has a limiting effect on the central frame 2 and the side frames 3. Especially for the side frames 3, the limitation of the bed frame 1 ensures that even if the central frame 2 rotates around the pivot, it will not cause the part of the side frame 3 supported on the bed frame 1 to fold downwards. It will only cause the side of the central frame 2 that rotates downwards on the bed frame 1 to move the hinge point between this side and the side frame 3 downwards. At the same time, the side of the side frame 3 away from the hinge point, that is, the side that was originally supported on the bed frame 1, will tilt upwards. The power for the turning mechanism 4 can come from an electric drive device, such as a motor, an electric push rod, or other drive methods. Based on the direction the patient is in when lying on the nursing bed, for example, the forward and reverse rotation of the motor can realize the forward and reverse rotation of the central frame 2, thereby realizing the patient's turning to the right or left. For example, when using an electric actuator, one end of the actuator is fixed to the bed frame 1, and the other end is connected to the central frame 2. The extension and retraction of the electric actuator pushes the central frame 2 to rotate around the pivot. In actual use, if the patient needs to turn to the left, the turning mechanism 4 is activated, driving the central frame 2 to rotate counterclockwise. The central frame 2 causes the right side frame 3 to fold upward, and the hinge point between the left side frame 3 and the central frame 2 moves downward, causing the left side edge of the left side frame 3 to tilt upward. If the patient needs to turn to the right, the turning mechanism 4 is activated, driving the central frame 2 to rotate clockwise. The central frame 2 causes the left side frame 3 to fold upward, and the hinge point between the right side frame 3 and the central frame 2 moves downward, causing the right side edge of the right side frame 3 to tilt upward.

[0039] In summary, the nursing bed disclosed herein, through the coordinated arrangement of the central frame 2, the two side frames 3, and the turning mechanism 4, eliminates the need for manual operation by nursing staff when turning patients, greatly reducing the workload of nursing staff and improving nursing efficiency. Through the reasonable frame structure design and the driving mechanism 4, the design of the central frame 2 increases the contact area between the patient's back and the frame structure during turning, enabling smooth and precise turning movements, reducing pulling and discomfort to the patient's body, improving the patient's comfort during the turning process, and conforming to ergonomics.

[0040] In one embodiment, the middle frame 2 has an initial state and a folded state. When the middle frame 2 is in the initial state, the middle frame 2 and the two side frames 3 are located in the same plane. When the middle frame 2 is in the folded state, the middle frame 2 and one of the two side frames 3 are located in the same plane, and the middle frame 2 and one of the two side frames 3 form an angle.

[0041] In this embodiment, when the central frame 2 is in its initial state, the central frame 2 and the two side frames 3 are located in the same plane, forming a complete and flat bed surface. This state is suitable for scenarios such as normal lying down and resting, and receiving general nursing care, providing stable and comfortable support for the patient. When the central frame 2 is in the folded state, the central frame 2 and one of the two side frames 3 are located in the same plane, while the central frame 2 and the other of the two side frames 3 form an angle. In practical applications, when it is necessary to help the patient turn to one side, such as to the left, the turning mechanism 4 is activated, causing the central frame 2 to rotate counterclockwise around the axis. As the central frame 2 rotates, the right side frame 3 will be raised accordingly, always remaining in the same plane as the central frame 2, while the left side frame 3 forms an angle with the central frame 2. This angle can effectively guide the patient's body to move in the direction of turning, while providing lateral support for the patient's movement, preventing the patient from accidentally slipping during the turning process. Therefore, in the folded state, the central frame 2 and the side frames 3 form an angled and plane-aligned structure, which better conforms to the patient's body curves, providing stable support during turning and effectively reducing the risk of slippage, thus greatly improving the safety of turning the patient. During turning, the patient's body can move naturally with the changes in the frame structure, enhancing patient comfort.

[0042] In one embodiment, the turning mechanism 4 includes a first driving component 41 and a support rod 42. The support rod 42 is arranged along the width direction of the bed frame 1 and is mounted on the bed frame 1 via a rotating shaft 43. The support rod 42 is connected to the middle frame 2. One end of the first driving component 41 is rotatably connected to the bed frame 1, and the other end is rotatably connected to the support rod 42. The first driving component 41 is used to drive the middle frame 2 to rotate around the rotating shaft.

[0043] In this embodiment, the first driving component 41 can specifically be an electric actuator or a motor, and its driving end is connected to the support rod 42 via a rotating structure. The support rod 42 is arranged along the width direction of the bed frame 1 and is mounted on the bed frame 1 via a rotating shaft 43, which provides a stable support point for the rotation of the support rod 42. The rotating shaft 43 and the rotating shaft of the middle frame 2 can be coaxial or non-coaxial. When they are coaxial, the rotation axis of the rotating shaft 43 of the support rod 42 coincides with the rotating shaft of the middle frame 2, which can achieve more direct torque transmission. If a non-coaxial design is adopted, the force is transmitted to the middle frame 2 through the support rod 42, and the support rod 42 and the middle frame 2 rotate around their respective axes. One end of the first driving component 41 is rotatably connected to the support rod 42. This method ensures that the first driving component 41 can effectively drive the support rod 42, while also allowing the support rod 42 to rotate flexibly within a certain range. When the first drive component 41 is working, the extension or rotation of its drive end will cause the support rod 42, which is hinged to it, to rotate around the rotation axis 43. Since the first drive component 41 is connected to the middle frame 2 through the support rod 42, the middle frame 2 can be supported on the support rod 42 and in contact with the support rod 42. Therefore, the rotation of the support rod 42 will be further transmitted to the middle frame 2, thereby causing the middle frame 2 to rotate around the rotation axis. The support rod 42 and the middle frame 2 can also be connected in a fixed manner. In this case, the support rod 42 directly serves as the supporting skeleton of the middle frame 2, and its rotational movement will be transmitted to the middle frame 2 completely synchronously. During the rotation of the middle frame 2, the two side frames 3 hinged to the middle frame 2 will fold upwards towards the bed frame 1 according to the movement of the middle frame 2, realizing the patient's turning function. Understandably, the support rod 42 is also connected to a long rod 44 that is set along the length of the bed frame 1. The long rod 44 can rotate with the rotation of the support rod 42. The long rod 44 contacts the side frame 3 to support the side frame 3 along the length of the bed frame 1, providing more stable support for the side frame 3.

[0044] Reference Figure 4 and Figure 6 As shown, in one embodiment, side support portions 11 are provided on both sides of the bed frame 1. The side support portions 11 are used to support the side frame 3 and restrict the side of the side support portion 11 away from the middle frame 2 from folding down towards the bed frame 1.

[0045] Specifically, in one embodiment, there are multiple side support portions 11, which are spaced apart along the length of the bed frame 1.

[0046] In this embodiment, the positions of these side support portions 11 are designed to match the side frame 3, enabling precise support of the side frame 3. The function of the side support portions 11 is to provide stable support for the side frame 3 during use of the nursing bed, especially when the patient turns over. The side support portions 11 effectively restrict the side of the side frame 3 away from the central frame 2 from folding downwards towards the bed frame 1, ensuring that this side can tilt upwards, forming an angle between the side frame 3 and the central frame 2. The side support portions 11 can adopt various structural forms. For example, they can be metal support frames fixed to both sides of the bed frame 1, effectively preventing excessive folding of the side frame 3 without affecting normal patient use; they can also be elastic support structures, such as rubber support pads, which provide support and, to some extent, cushion the pressure on the side frame 3, reducing noise and vibration; rollers can also be installed at the contact points between the side frame 3 and the side support portions 11, also serving a cushioning function. It is understood that the side support portions 11 can be optionally placed at locations corresponding to the back, buttocks, etc., of the patient to enhance support.

[0047] Reference Figure 7 As shown, in one embodiment, the middle frame 2 includes an upper limb main frame 21, a hip main frame 22, a thigh main frame 23, and a lower leg main frame 24 that are hinged to each other and arranged along the length of the bed frame 1. The side frame 3 includes an upper limb side frame 31, a hip side frame 32, a thigh side frame 33, and a lower leg side frame 34 that are hinged to each other and arranged along the length of the bed frame 1. The two upper limb side frames 31 are respectively arranged on both sides of the upper limb main frame 21 along the width of the bed frame 1 and are connected to the upper limb main frame 21. The upper limb frame assembly is formed by hinges. Two buttock side frames 32 are located on either side of the main buttock frame 22 along the width of the bed frame 1 and are hinged to the main buttock frame 22 to form a buttock frame assembly. Two thigh side frames 33 are located on either side of the main thigh frame 23 along the width of the bed frame 1 and are hinged to the main thigh frame 23 to form a thigh frame assembly. Two lower leg side frames 34 are located on either side of the main lower leg frame 24 along the width of the bed frame 1 and are hinged to the main lower leg frame 24 to form a lower leg frame assembly. A commode opening 221 is provided in the middle of the main buttock frame 22.

[0048] In this embodiment, the central frame 2 consists of an upper limb main frame 21, a hip main frame 22, a thigh main frame 23, and a lower leg main frame 24, which are hinged to each other and arranged along the length of the bed frame 1. This allows the central frame 2 to rotate relatively flexibly under the drive of the turning mechanism 4, thereby better conforming to the changes in the patient's body curves during movements such as turning over and sitting up. For example, when the patient needs to turn over, the upper limb main frame 21, hip main frame 22, thigh main frame 23, and lower leg main frame 24 can rotate in coordination to ensure a natural transition for the patient's body and reduce discomfort caused by an unreasonable frame structure. The various parts of the side frame 3 are closely integrated with the central frame 2, providing stable lateral support when the patient turns over, preventing the patient from slipping off the bed, and also ensuring the integrity and comfort of the bed surface when the patient is lying down normally. The components of the central frame 2 and side frames 3 work together, and with the coordinated action of the turning mechanism 4, bed frame 1, and other parts, they enable the nursing bed to perform multiple functions. When the turning mechanism 4 is activated, it drives the central frame 2 to rotate around its axis, which in turn drives the side frames 3 to move accordingly through the hinge structure, thus enabling the patient to turn over. During daily use, all frame assemblies work together to provide stable and comfortable support for the patient, meeting their different lying posture needs.

[0049] Reference Figure 6 As shown, in one embodiment, at least one central support frame 12 is provided on the center line of the bed frame 1, and the pivot is provided on the central support frame 12.

[0050] Furthermore, in one embodiment, the bed frame 1 is also provided with a support part 13 for supporting one end of the middle frame 2 corresponding to the human head. There are two sets of middle support frames 12, and the support part 13 is coaxially arranged with the two rotating shafts.

[0051] In this embodiment, the number of central support frames 12 can be flexibly adjusted according to the length, width, and load-bearing requirements of the bed frame 1. For example, for a longer or wider bed frame 1, multiple central support frames 12 can be provided to ensure uniform support. Preferably, a load-bearing portion 13 is provided on the bed frame 1, which is specifically designed to support the end of the central frame 2 corresponding to the human head. The design of the load-bearing portion 13 fully considers the weight distribution and force characteristics of the human head, providing comfortable and stable support for the patient's upper limbs, especially the head. The surface of the load-bearing portion 13 can be made of a material with a certain degree of elasticity, such as rubber or sponge, which can both buffer head pressure and ensure the stability of the support, effectively relieving neck pressure on the patient. There are two sets of central support frames 12, which are distributed along the length of the bed frame 1 and jointly support the central frame 2. One of the two sets of central support frames 12 is set on the central frame 2 at a position corresponding to the waist of the human body, and the other of the two sets of central support frames 12 is set on the central frame 2 at a position corresponding to the buttocks of the human body. Thus, the three points of the bearing part 13 and the two rotating shafts correspondingly set on the two central support frames 12 are collinear to form a central axis, providing stable support for the central frame 2.

[0052] Reference Figures 8-10 As shown, in one embodiment, the nursing bed further includes a backrest lifting mechanism, a leg lifting mechanism, and a bed-moving mechanism 5. One end of the backrest lifting mechanism is connected to the upper limb frame assembly and is used to drive the upper limb frame assembly to rotate about its hinge point with the hip frame assembly toward the top of the bed frame 1. The leg lifting mechanism is connected to the thigh frame assembly and is used to drive the thigh frame assembly to rotate about its hinge point with the hip frame assembly toward the top or bottom of the bed frame 1. The bed-moving mechanism 5 is located below the bed frame 1 and includes a first drive assembly, a bedpan, a linkage assembly, and a cover. The first drive assembly is used to drive the linkage assembly to rotate so that the bedpan and the cover are alternately positioned below the bed opening 221.

[0053] In this embodiment, the back-lifting mechanism can employ power devices such as electric push rods or hydraulic rods. Taking an electric push rod as an example, the extension and retraction of the electric push rod can precisely control the rotation angle of the upper limb frame assembly, thereby meeting the patient's different back-lifting needs, such as semi-reclining or sitting positions. The leg-lifting mechanism can also be equipped with electric push rods or hydraulic devices. By controlling the leg-lifting mechanism, the height and angle of the patient's legs can be adjusted, helping the patient relieve leg fatigue and reduce swelling. When the patient needs to defecate, the first drive assembly drives the linkage assembly to move the bedpan below the urinal hole 221 for the patient's convenience. When the bedpan is no longer needed, the first drive assembly drives the linkage assembly again to move the bedpan away, and at the same time, the cover moves below the urinal hole 221 to provide cover and maintain hygiene.

[0054] In one embodiment, the nursing bed further includes a guardrail mechanism 6, which includes a first railing, a second railing, and a plurality of support rods. One end of each support rod is hinged to the first railing, and the other end is hinged to the second railing, so that the guardrail mechanism 6 can switch between an unfolded state and a folded state.

[0055] In this embodiment, the first and second railings are arranged in parallel. The first railing, the second railing, and multiple support rods together define the protective area in the unfolded state of the guardrail mechanism 6, enabling the guardrail mechanism 6 to fold and unfold. Each support rod is hinged at both ends to the first and second railings, allowing the guardrail mechanism 6 to flexibly switch between the unfolded and folded states. Simultaneously, the distance between adjacent support rods is equal to or greater than the length of each support rod, ensuring that in the folded state, the second railing can engage with the support rods, and the support rods can engage with the first railing. This makes the folded guardrail mechanism 6 more compact, reducing space occupation, and also increases the stability of the guardrail in the folded state, preventing the support rods from swaying unnecessarily.
