[0036] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0038] Please refer to Figure 1 The present embodiment provides a nursing bed 001, which can be used as a medical bed for patients and can also be used as a home bed. When using the nursing bed 001, it is convenient for patients to get on and off the bed.

[0039] See also Figure 1 and Figure 2 The nursing bed 001 provided in this embodiment includes a bed frame 100, a bed board assembly 200 and a guardrail 300. The bed board assembly 200 has a support portion for supporting a patient. The bed board assembly 200 is movably connected to the bed frame 100 to adjust the posture of the patient on the support portion; the guardrail 300 is rotatably connected to the bed frame 100, and the guardrail 300 has a first position and a second position. When the guardrail 300 is located at the first position, the guardrail 300 protrudes from the support portion in the height direction of the bed frame 100 to prevent the patient from falling from the side of the bed board assembly 200 in its width direction; when the guardrail 300 is located at the second position, the guardrail 300 does not protrude from the support portion.

[0040] The nursing bed 001 provided in this embodiment, when the initial state is set, the guardrail 300 is located in the first position, and the guardrail 300 protrudes the support part. When the patient needs to get on or off the bed, the guardrail 300 is first rotated relative to the bed frame 100 to a set angle so that the guardrail 300 moves from the first position to the second position. At this time, the guardrail 300 does not protrude the support part for supporting the patient, and the guardrail 300 will not hinder the patient from getting on or off the bed, and the patient is convenient to get on and off the bed. After the patient gets on the bed, the guardrail 300 can be rotated from the second position to the first position again, and the guardrail 300 protrudes the support part in the height direction of the bed frame 100, which can prevent the patient from falling from the side of the bed frame 100 in its width direction, thereby improving safety. At the same time, the nursing bed 001 includes a bed board assembly 200 installed on the bed frame 100, and the bed board assembly 200 can move relative to the bed frame 100 to adjust the position relative to the bed frame 100, thereby adjusting the patient's posture, and can adapt to the different needs of the patient, improve comfort, and facilitate the patient's rehabilitation.

[0041] It should be noted that when the guardrail 300 is rotated from the first position to the second position, the guardrail 300 can be in a horizontal state, thereby increasing the width of the support portion and increasing the available area of ​​the nursing bed 001. Obviously, the guardrail 300 can continue to rotate so that the guardrail 300 is located below the bed frame 100, and the guardrail 300 has no part protruding from the side wall of the bed frame 100, which is not easy to block the patient from getting on and off the bed, and the patient is more convenient to get on and off the bed. It should be understood that during use, the rotation angle of the guardrail 300 is selected as needed and is not specifically limited here.

[0042] In this embodiment, the bed board assembly 200 includes a plurality of support members, which are arranged along the length direction of the bed frame 100. At least one of the plurality of support members is movably connected to the bed frame 100 to adjust the posture of the patient on the support portion. When in use, after one of the plurality of support members rotates relative to the bed frame 100, the shape of the support portion can be adjusted to enable the patient to perform actions such as bending legs, lifting back or bending waist, which is convenient for the patient to use.

[0043] Optionally, the nursing bed 001 further comprises a mattress, which is supported by a support part. In other words, the mattress is laid on the bed board assembly 200 and is supported by a plurality of support sub-parts, so that the patient can use the bed more comfortably. By adjusting the relative positions of the plurality of support sub-parts to adjust the shape of the mattress, the mattress can be folded to accommodate the patient's movements such as bending legs, raising the back, and turning over.

The first support 210 and the second support 220 are rotatably connected, and the second support 220 and the bed frame 100 are rotatably connected. The first support 210 can rotate relative to the second support 220 to achieve an elevation angle or a depression angle relative to the horizontal plane, and at the same time, it can drive the second support 220 to rotate relative to the bed frame 100 so that the second support 220 has an elevation angle or a depression angle. The third support 230 is rotatably connected to the bed frame 100, and the angle between the third support 230 and the bed frame 100 can be adjusted. A support sub-section is provided on each support, and a plurality of support sub-sections on a plurality of support members together form a support portion for supporting a patient. Since the multiple supporting sub-sections are independently arranged, the position of each supporting sub-section can be adjusted, so that the entire supporting section may not be located on the same plane, so as to enable the patient to maintain different postures when supporting the patient. The first driving assembly 400 is connected to the bed frame 100, and the first driving assembly 400 is used to drive the first supporting member 210 to rotate relative to the second supporting member 220. The second driving assembly 500 is connected to the bed frame 100, and the second driving assembly 500 is used to drive the third supporting member 230 to rotate relative to the bed frame 100.

[0045] Optionally, the first support member 210 and the second support member 220 cooperate to support the patient's legs and assist the patient in bending his legs.

[0046] Optionally, the first support member 210 includes three support blocks 250, which are arranged along the width direction of the bed frame 100, and adjacent support blocks 250 are rotatably connected. The first driving assembly 400 abuts against the middle support block 250 to drive the middle support block 250 to rotate relative to the second support member 220.

[0047] Optionally, the second support member 220 includes three support blocks 250, which are arranged along the width direction of the bed frame 100, and adjacent support blocks 250 are rotatably connected. The three support blocks 250 of the first support member 210 correspond one-to-one to the three support blocks 250 of the second support member 220 and are rotatably connected.

[0048] See also Figure 3 Optionally, the first driving assembly 400 includes a first driving member and a transmission member 410, the first driving member is disposed on the bed frame 100, the first driving member is connected to the transmission member 410, the transmission member 410 is connected to the first support member 210, and the first driving member drives the transmission member 410 to move to drive the first support member 210 to rotate. The first driving member can be a cylinder, a hydraulic cylinder or a screw transmission structure.

[0049] Optionally, the intermediate support member 240 is provided with a drain port 241. The drain port 241 can be opened or closed.

[0050] Optionally, the third support member 230 includes a plurality of support blocks 250, the plurality of support blocks 250 include side support blocks 250 located on both sides of the bed frame 100 in the width direction and a back support block 250 and a head support block 250 located between the two side support blocks 250, the back support block 250 and the head support block 250 are rotatably connected, and the two side support blocks 250 are rotatably connected to the back support block 250 and the head support block 250 at the same time.

[0051] It should be noted that each support block 250 is an independent structure. Each support block 250 includes a base plate and a cushion. The cushion is connected to the base plate to improve the flexibility of the bed board assembly 200 and make it more comfortable to use.

[0052] Optionally, the second driving assembly 500 is connected to the bed frame 100 and is used to drive the back support block 250 to rise and fall relative to the bed frame 100 to lift the patient's back.

[0053] Optionally, the nursing bed 001 also includes a support frame 700 and a third drive assembly 600. The support frame 700 is rotatably connected to the bed frame 100, and the rotation axis of the support frame 700 and the bed frame 100 extends along the length direction of the bed frame 100. The bed board assembly 200 is connected to the support frame 700. In other words, the first support member 210, the second support member 220, the intermediate support member 240, and the third support member 230 are all connected to the support frame 700, and the support frame 700 is rotatably connected to the bed frame 100. The rotation axis of the support frame 700 and the bed frame 100 is perpendicular to the rotation axis of the third support member 230. Obviously, in other embodiments, the rotation axes of the two can be at other angles. After the support frame 700 rotates, the height of the support frame 700 on both sides of the bed frame 100 in the width direction can be adjusted, thereby adjusting the inclination state of the support portion to adapt to the patient's turning over. The third drive assembly 600 is connected to the bed frame 100 and is used to drive the support frame 700 to rotate relative to the bed frame 100. The second driving assembly 500 is connected to the support frame 700 and is used to drive the third support member 230 to rotate relative to the support frame 700 .

[0054] Optionally, the second drive assembly 500 includes a cylinder, a hydraulic cylinder or a screw transmission structure. The third drive assembly 600 includes a cylinder, a hydraulic cylinder or a screw transmission structure.

[0055] Optionally, the support frame 700 is provided with a plurality of connecting lugs arranged at intervals along its length direction, and the number of connecting lugs may be two, and the two connecting lugs are simultaneously rotatably connected to the bed frame 100. By rotating the support frame 700, the entire bed board assembly 200 can be driven to rotate, thereby driving the mattress to fold and adapt to the patient's turning over.

[0056] See also Figure 4-Figure 7 Optionally, the nursing bed 001 further includes a limit assembly 800, which is connected to the third support member 230 and the support frame 700 at the same time, and is used to lock the third support member 230 after the third support member 230 rotates to a set position along the first direction under the drive of the second drive assembly 500, thereby preventing the third support member 230 from rotating in a second direction opposite to the first direction. After adjusting the position of the third support member 230, the locking effect of the limit assembly 800 can reduce the pressure applied to the second drive assembly 500, and the second drive assembly 500 is not easily damaged, which prolongs the service life of the second drive assembly 500, and also avoids the third support member 230 from returning to the initial position after the supporting force of the second drive assembly 500 fails, thereby improving safety.

[0057] Furthermore, the limiting assembly 800 includes a first clamping member 810, a second clamping member 820 and a limiting member 830. The second driving assembly 500 is connected to the support frame 700 and is used to drive the third support member 230 to rotate relative to the support frame 700. The first clamping member 810 is rotatably connected to the third support member 230. The first clamping member 810 is provided with a first clamping port 811 and a second clamping port 812 that are connected. The first clamping port 811 and the second clamping port 812 have an angle. The second clamping member 820 includes a connected plug-in portion 821 and The connecting portion 822, the plug-in portion 821 and the connecting portion 822 are rotatably connected to the support frame 700 at the connection position through the first rotating shaft 840, the plug-in portion 821 is slidably matched with the first clamping member 810, and can slide back and forth between the first clamping port 811 and the second clamping port 812; the limiting member 830 is rotatably connected to the support frame 700 through the second rotating shaft 850, the support frame 700 has a supporting portion for abutting against the limiting member 830 to limit the limiting member 830 from rotating close thereto, and the connecting portion 822 is rotatably matched with the limiting member 830. Optionally, the limiting member 830 is provided with a limiting clamping port 831, and the connecting portion 822 is rotatably matched with the limiting clamping port 831.

[0058] The third support member 230 is set to be horizontal in the initial state. When the patient needs to sit, the second driving assembly 500 is started to drive the third support member 230 to rotate along the first direction, thereby driving the first clamping member 810 to rotate along the first direction, so that the plug-in portion 821 slides from the first clamping member 811 to the second clamping member 812. When the third support member 230 has a tendency to rotate along a second direction opposite to the first direction, the first clamping member 810 drives the connecting portion 822 to have a tendency to rotate along the first direction, so that the limiting member 830 has a tendency to rotate along the second direction opposite to the first direction, thereby causing the limiting member 830 to abut against the abutting portion to limit the rotation of the third support member 230 along the second direction and lock the third support member 230. Because the angled third support member 230 has a tendency to return to a horizontal state under the action of gravity, the third support member 230 is supported by the limiting assembly 800 and the second drive assembly 500 at the same time. The load of the third support member 230 acting on the second drive assembly 500 is partially shared by the limiting assembly 800, which reduces the load acting on the second drive assembly 500. The second drive assembly 500 is not easily damaged, thereby extending the service life of the second drive assembly 500 and improving safety. When it is necessary to unlock the third support member 230, the third support member 230 continues to rotate in the first direction under the drive of the second drive assembly 500 to drive the first clamping member 810 to rotate in the first direction. Since the rotation of the second clamping member 820 in the second direction is not restricted, the first clamping member 810 can drive the second clamping member 820 to rotate in the second direction, so that the plug-in portion 821 is unlocked from the second bayonet 812 and slides into the first bayonet 811, thereby releasing the restriction on the rotation of the first clamping member 810 in the second direction, so that the third support member 230 can rotate in the second direction.

[0059] In this embodiment, optionally, the nursing bed 001 also includes a toilet, which is installed on the bed frame 100 and is located below the bed board assembly 200, and the inlet of the toilet corresponds to the discharge port 241 on the middle support member 240 to better collect excrement.

[0060] In this embodiment, the nursing bed 001 may further include a table top 900, which is detachably connected to the guardrail 300. Optionally, guardrails 300 are provided on both sides of the width direction of the bed frame 100 assembly, and two opposing guardrails 300 form a group, and a group of guardrails 300 may jointly support a table top 900. Optionally, a through slot is provided on the table top 900, and the through slot on the table top 900 is detachably engaged with the guardrail 300.

[0061] Optionally, brakeable wheels are installed at the bottom of the bed frame 100.

[0062] The nursing bed 001 provided in this embodiment can adjust the state of the mattress as needed to accommodate the patient's movements such as bending legs, raising the back or turning over, and can facilitate patients getting on and off the bed by changing the position of the guardrail 300.

[0063] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
