Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary equipment technology, specifically relating to a nursing bed. Background Technology

[0002] To facilitate patient care, various types of nursing beds exist in the current technology, designed to support patients' daily lives or to allow medical staff to position patients in specific lying positions according to medical needs. Existing nursing beds can be broadly categorized into two types: one uses a system where the entire bed frame can be raised or lowered to adjust its horizontal height for easy patient transport; the other adjusts the patient's lying position by changing the tilt angle of the bed board. In the current technology, adjusting the height and tilt angle of nursing beds requires different drive mechanisms. Utility Model Content

[0003] To solve the above-mentioned technical problems, it is necessary to provide a nursing bed that simplifies the drive mechanism and has the functions of adjusting the height of the bed frame and the overall tilt angle.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A nursing bed includes a bed frame base and a bed frame, further comprising a first drive mechanism and a second drive mechanism movably connected to the bed frame, a first leg assembly connected to the output end of the first drive mechanism, and a second leg assembly connected to the output end of the second drive mechanism; the first leg assembly includes a first support member supported between the bed frame and the bed frame base, the first support member being rotatably connected to the bed frame base and slidable on the bed frame to adjust the support angle; the second leg assembly includes a second support member supported between the bed frame and the bed frame base, the second support member being rotatably connected to the bed frame base and slidable on the bed frame. The first support leg assembly further includes a first connecting member whose one end is movably connected to the output end of the first drive mechanism and whose other end is movably connected to the first support member. The second support leg assembly further includes a second connecting member whose one end is movably connected to the output end of the second drive mechanism and whose other end is movably connected to the second support member. Of the output ends of the first drive mechanism and the second drive mechanism, one always faces the head of the bed and the other always faces the foot of the bed. The output end of the first drive mechanism extends and retracts to drive the first support member to adjust its support angle, and the output end of the second drive mechanism extends and retracts to drive the second support member to adjust its support angle.

[0006] In the nursing bed provided by this utility model, when the first drive mechanism and the second drive mechanism move synchronously, the tilt angle of the drive mechanism support remains unchanged. The first leg assembly and the second leg assembly move synchronously, and the first support member and the second support member slide on the bed frame, changing the support angle and thus adjusting the distance between the bed frame and the bed frame base. The bed frame is raised or lowered relative to the bed frame base as a whole. The first connector and the second connector provide movement space. This connection method allows the two drive mechanisms to move independently rather than synchronously. When the first drive mechanism and the second drive mechanism move asynchronously, the tilt angle of the bed frame relative to the bed frame base changes. The nursing bed provided by this utility model can adjust both the height of the bed frame horizontally and the overall tilt angle of the bed frame. By changing the overall tilt angle of the bed frame, the patient can be conveniently adjusted to a head-high-feet-low position or a head-low-feet-high position to meet medical needs.

[0007] Preferably, the first support member is bolted to the bed frame base, which further includes a support slide rail. The second leg assembly includes a support slider that cooperates with the support slide rail. The second support member is connected to the support slider and can slide along the support slide rail. In this structure, the end of the second support member that is rotatably connected to the bed frame base can also slide, increasing the range of motion of the second support member. The distance between the first and second support members connected to one end of the bed frame base can be shortened under the drive of the drive mechanism. That is, the maximum upright angle of the first and second support members increases, and the maximum height to which the bed frame can be raised relative to the bed frame base increases. This structure not only allows the bed frame to be raised to a higher height, but also ensures smooth and gentle movement due to sliding along the support rail. Furthermore, the horizontal displacement of the bed frame can be controlled by the position of the support rail. For example, the support rail is set near the head of the bed, and the first support is bolted near the foot of the bed. Since the bolting point of the first support is fixed, the bed frame will naturally be pulled towards the foot of the bed during the lifting process. However, nursing beds using other overall lifting schemes in the prior art may move towards the head of the bed when raised. The head of the bed is often set against the wall, which can easily cause damage to the wall. If space is reserved for movement in the direction of the head of the bed, it will affect the layout of the ward.

[0008] Preferably, the first support member includes a left support leg and a right support leg spaced apart from each other, and a support link connecting the left support leg and the right support leg, wherein the first connector is rotatably connected to the support link.

[0009] Preferably, the bed frame further includes a left slide rail corresponding to the left support leg and a right slide rail corresponding to the right support leg. The left support leg includes a left slider that cooperates with the left slide rail, and the right support leg includes a right slider that cooperates with the right slide rail. The left slide rail and the right slide rail are parallel.

[0010] Preferably, the first support member further includes a support crossbar, the direction of which is parallel to the width direction of the bed frame, and both ends are rotatably connected to the bed frame base, and the left and right support legs are connected to the support crossbar.

[0011] Preferably, the first support member further includes a left reinforcing rod with one end bolted to the left support leg and the other end bolted to the bed frame, and a right reinforcing rod with one end bolted to the right support leg and the other end bolted to the bed frame. The use of reinforcing rods in this structure increases the stability of the support member.

[0012] Preferably, the bed frame includes two longitudinal bars facing each other end-to-end, and two transverse bars straddling the two longitudinal bars. The two transverse bars are spaced apart and located in the middle section of the two longitudinal bars. The bed frame also includes a drive mechanism support connected to the two transverse bars. The main bodies of the first drive mechanism and the second drive mechanism are rotatably connected to the drive mechanism support. The first drive mechanism and the second drive mechanism are connected to the same drive mechanism support, which facilitates installation and adjustment, and prevents deformation during movement.

[0013] Preferably, the nursing bed further includes an adjustable backrest assembly and a backrest drive mechanism connected to the bed frame. The adjustable backrest assembly is connected to the two crossbars and located on the side near the head of the bed. It includes a mattress support frame and a movable connector. One end of the movable connector is connected to the mattress support frame, and the other end is slidably connected to the bed frame. The main body of the backrest drive mechanism is rotatably connected to the bed frame, and its output end is rotatably connected to the adjustable backrest assembly. The output end of the backrest drive mechanism extends and retracts to cause the mattress support frame to stand up and slide towards the head of the bed, or return to its original position.

[0014] Preferably, the mattress support frame includes a bottom rod near the two crossbars, the bottom rod being connected to the movable connector. The adjustable back panel assembly further includes an intermediate connecting assembly, which includes a fixed rod, a rod support, and a rotating connector sleeved on the fixed rod. The rod support is connected to the bottom rod, the fixed rod is mounted on the rod support and the movable connector, and the output end of the back panel drive mechanism is rotatably connected to the rotating connector.

[0015] Preferably, the movable connectors include a left movable member and a right movable member. The adjustable back panel assembly further includes a left support rod with one end rotatably connected to the bed frame and the other end rotatably connected to the left movable member, and a right support rod with one end rotatably connected to the bed frame and the other end rotatably connected to the right movable member. The bed frame has a left sliding groove corresponding to the left movable member and a right sliding groove corresponding to the right movable member. One end of the fixed rod is connected to a rod support, and the other end is connected to either the left or right movable member. This structure features two sets of movable connectors and support rods symmetrically arranged, making the structure more stable.

[0016] Preferably, the drive mechanism support is located on the central axis of the bed frame, and the backrest drive mechanism is connected to the side of the drive mechanism support. In this structure, the drive mechanism support that supports the entire weight of the bed frame is located on the central axis of the bed frame, while the backrest drive mechanism for adjusting the backrest is connected to the side of the drive mechanism support. The layout is reasonable and the two mechanisms do not interfere with each other. Attached Figure Description

[0025] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0026] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] refer to Figure 1 and Figure 3The present invention discloses a nursing bed, comprising a bed frame base 1 and a bed frame 2, and further comprising a first drive mechanism 31 and a second drive mechanism 32 movably connected to the bed frame 2, a first support leg assembly 4 connected to the output end of the first drive mechanism 31, and a second support leg assembly 5 connected to the output end of the second drive mechanism 32. The first support leg assembly 4 includes a first support member 41 supported between the bed frame 2 and the bed frame base 3, the first support member 41 being rotatably connected to the bed frame base 1 and slidable on the bed frame 2 to adjust the support angle. The second support leg assembly 5 includes a second support member 51 supported between the bed frame 2 and the bed frame base 1, the second support member 51 being rotatably connected to the bed frame base 1 and slidable on the bed frame 2 to adjust the support angle. The bed frame 2 slides to adjust the support angle; the first leg assembly 4 further includes a first connector 42 with one end movably connected to the output end of the first drive mechanism 31 and the other end movably connected to the first support member 41; the second leg assembly 5 further includes a second connector 52 with one end movably connected to the output end of the second drive mechanism 32 and the other end movably connected to the second support member 51; of the output ends of the first drive mechanism 31 and the second drive mechanism 31, one always faces the head of the bed and the other always faces the foot of the bed; the output end of the first drive mechanism 31 extends and retracts to drive the first support member 41 to adjust the support angle, and the output end of the second drive mechanism 32 extends and retracts to drive the second support member to adjust the support angle.

[0029] In the nursing bed provided by this utility model, when the first drive mechanism 31 and the second drive mechanism 32 move synchronously, the first leg assembly 4 and the second leg assembly 5 move synchronously, and the first support member 41 and the second support member 51 slide on the bed frame 2, changing the support angle and thus adjusting the distance between the bed frame 2 and the bed frame base 1. The bed frame 2 is raised or lowered relative to the bed frame base 1 as a whole. The first connecting member 42 and the second connecting member 52 provide movement space. This connection method allows the two drive mechanisms to move independently rather than being limited to synchronous movement. When the first drive mechanism 31 and the second drive mechanism move asynchronously, the tilt angle of the bed frame 2 relative to the bed frame base 1 changes. The nursing bed provided by this utility model can adjust the height of the bed frame 2 horizontally and also adjust the overall tilt angle of the bed frame 2. By changing the overall tilt angle of the bed frame 2, the patient can be conveniently adjusted to a head-high-feet-low position or a head-low-feet-high position to meet medical needs.

[0030] In the preferred embodiment, the bed frame base 1 comprises a square frame, and casters are provided at the corners of the bed frame base 1 for easy pushing. The bed frame 2 is longer and narrower than the bed frame base 1, and is supported by the bed frame base 1 when the bed frame 2 is lowered to its lowest position. In other embodiments, the bed frame base 1 and the bed frame 2 can be any other shape, as long as the bed frame 2 can move relative to the bed frame base 1. In the preferred embodiment, the drive mechanism support 3 is connected to the bed frame 2 near the center, is elongated, and parallel to the length direction of the bed frame 2. The main bodies of the first drive mechanism 31 and the second drive mechanism 32 are connected close to one end of the drive mechanism support 3. In other embodiments, the drive mechanism support 3 can also be of other shapes, and its position can be not at the center of the bed frame 2, as long as it can drive the bed frame 2 to tilt as a whole. The first drive mechanism 31 and the second drive mechanism 32 can also be connected to the drive mechanism support 3 without being close to each other, and the bed frame 2 can be moved relative to the bed frame base 1 by the extension and retraction of the output end. In the preferred embodiment, the first support member 41 and the second support member 51 are respectively provided with sliders, and the bed frame 2 is provided with slide rails. The first support member 41 and the second support member 51 slide on the bed frame 2 through the cooperation of the sliders and the slide rails. In other embodiments, there may be no sliders and slide rails. For example, the first support member 41 and the second support member 51 may each have only one support leg, and the top of the leg is provided with a pulley, which can slide on the bottom surface of the bed frame 2. The first support member 41 and the second support member 51 may also be any other structure.

[0031] refer to Figure 1In a preferred embodiment, the first support member 41 is bolted to the bed frame base 1, and the bed frame base 1 further includes a support slide rail 11. The second leg assembly 5 includes a support slider 50 that cooperates with the support slide rail 11. The second support member 51 is connected to the support slider 50 and can slide along the support slide rail 11. In this structure, the end of the second support member 51 that is rotatably connected to the bed frame base 1 can also slide, increasing the range of motion of the second support member 51. The distance between the first support member 41 and the second support member 51 connected to one end of the bed frame base 1 can be shortened under the drive of the drive mechanism. That is, the maximum upright angle of the first support member 41 and the second support member 51 increases, and the maximum height at which the bed frame 2 can be raised relative to the bed frame base 1 increases. This structure not only allows the bed frame 1 to be raised to a higher height, but also ensures a smooth and gentle movement process due to sliding along the support track 11. Furthermore, the horizontal displacement of the bed frame 2 can be controlled by the setting position of the support track 11. For example, the support rail 11 is set near the head of the bed, and the first support member 41 is bolted near the foot of the bed. Since the bolting point of the first support member 41 is fixed, the bed frame 2 will be naturally pulled towards the foot of the bed during the lifting process. However, nursing beds using other overall lifting schemes in the prior art may move towards the head of the bed when raised. The head of the bed is often set against the wall, which can easily cause damage to the wall. If space is reserved for movement in the direction of the head of the bed, it will affect the layout of the ward.

[0032] refer to Figure 4 In a preferred embodiment, the first support member 41 includes a left support leg 411 and a right support leg 412 spaced apart from each other, and a support connecting rod 413 connecting the left support leg 411 and the right support leg 412. The first connecting member 42 is rotatably connected to the support connecting rod 413. In the preferred embodiment, one end of the first connecting member 42 is sleeved on the support connecting rod 413, and the other end is bolted to the output end of the first drive mechanism 31. In other embodiments, the first connecting member 42 may also be a straight rod with both ends bolted to the support connecting rod 413 and the first drive mechanism 31, respectively.

[0033] refer to Figure 1 and Figure 2In a preferred embodiment, the bed frame 2 further includes a left slide rail 211 corresponding to the left support leg 411 and a right slide rail 212 corresponding to the right support leg 412. The left support leg 411 includes a left slider 4110 that cooperates with the left slide rail 211, and the right support leg 412 includes a right slider 4120 that cooperates with the right slide rail 212. The left slide rail 211 and the right slide rail 212 are parallel. In the preferred embodiment, the left slide rail 211 and the right slide rail 212 are respectively connected to the middle section of the main body of the bed frame 2. The sliders are located on the sides of the support legs. The first support member 41 and the second support member 51 have the same structure and share the left and right slide rails 212. In other embodiments, the first support member 41 and the second support member 51 may correspond to different left and right slide rails 212, and the sliders and slide rails may also be located in other positions.

[0034] refer to Figure 5 In a preferred embodiment, the first support member 41 further includes a support crossbar 414, the direction of which is parallel to the width direction of the bed frame 2, and both ends are rotatably connected to the bed frame base 1. The left support leg 411 and the right support leg 412 are connected to the support crossbar 414.

[0035] refer to Figure 5 In a preferred embodiment, the first support member 41 further includes a left reinforcing rod 415, one end of which is bolted to the left support leg 411 and the other end of which is bolted to the bed frame 2, and a right reinforcing rod 416, one end of which is bolted to the right support leg 412 and the other end of which is bolted to the bed frame 2. The use of reinforcing rods in this structure increases the stability of the support member and does not affect the raising and lowering of the bed frame 2 relative to the bed frame base 1. In the preferred embodiment, the end of the reinforcing rod bolted to the support leg is approximately located in the middle of the support leg, and the end of the reinforcing rod bolted to the bed frame 2 and the end of the support crossbar 414 bolted to the bed frame base 1 are horizontally similar in position.

[0036] refer to Figure 2 In a preferred embodiment, the bed frame 2 includes two longitudinal bars 201 facing end-to-end, and two transverse bars 202 straddling the two longitudinal bars 201. The two transverse bars 202 are spaced apart and located in the middle section of the two longitudinal bars 201. The bed frame 2 also includes a drive mechanism support 3 connected to the two transverse bars 202. The main bodies of the first drive mechanism 31 and the second drive mechanism 32 are rotatably connected to the drive mechanism support 3. The first drive mechanism 31 and the second drive mechanism 32 are connected to the same drive mechanism support 3, which facilitates installation and adjustment, and prevents deformation during movement.

[0037] The drive mechanism support 3 is connected to the two crossbars 202. The drive mechanism support 3 is connected to the two crossbars 202 located in the middle section of the bed frame 2, and acts as a lever arm, making it easier for the first drive mechanism 31 and the second drive mechanism 32 connected to the drive mechanism support 3 to drive the bed frame 2 as a whole to move, and the movement process is relatively stable.

[0038] refer to Figure 6 In a preferred embodiment, the nursing bed further includes an adjustable backrest assembly 6 and a backrest drive mechanism 7 connected to the bed frame 2. The adjustable backrest assembly 6 is connected to the two crossbars 202, located on the side near the head of the bed, and includes a mattress support frame 61 and a movable connector. One end of the movable connector is connected to the mattress support frame 61, and the other end is slidably connected to the bed frame 2. The main body of the backrest drive mechanism 7 is rotatably connected to the bed frame 2, and its output end is rotatably connected to the adjustable backrest assembly 6. The output end of the backrest drive mechanism 7 extends and retracts, causing the mattress support frame to stand up and slide towards the head of the bed, or return to its original position. In this structure, the mattress support frame 61 slides towards the head of the bed while standing up, counteracting the tendency of the user's waist and abdomen to be compressed, thus improving the user's experience.

[0039] refer to Figure 6 In a preferred embodiment, the mattress support frame 61 includes a bottom rod 610 near the two crossbars 202, which is connected to the movable connector. The adjustable backrest assembly 6 further includes an intermediate connecting assembly 62, which includes a fixed rod 621, a rod support 622, and a rotating connector 623 sleeved on the fixed rod 621. The rod support 622 is connected to the bottom rod 610, and the fixed rod 621 is mounted on the rod support 622 and the movable connector. The output end of the backrest drive mechanism 7 is rotatably connected to the rotating connector 623. When using the backrest adjustment function, the user may accidentally get caught in the gap between the mattress support frame 61 and the bed frame 2. The structure of the movable connector provides additional space for movement, allowing the mattress support frame 61 to be manually lifted to release the trapped part in the event of a sudden power outage or malfunction of the backrest drive mechanism 7, thus improving safety.

[0040] refer to Figure 6In a preferred embodiment, the movable connectors include a left movable member 63 and a right movable member 64. The adjustable back panel assembly 6 further includes a left support rod 65, one end of which is rotatably connected to the bed frame 2 and the other end of which is rotatably connected to the left movable member; and a right support rod 66, one end of which is rotatably connected to the bed frame 2 and the other end of which is rotatably connected to the right movable member. The bed frame 2 has a left sliding groove 221 corresponding to the left movable member 63 and a right sliding groove 222 corresponding to the right movable member 64. One end of the fixed rod 621 is connected to the rod support 622, and the other end is connected to either the left movable member 63 or the right movable member 64. The use of support rods 413 to support the mattress support frame 61 increases the load-bearing capacity and structural stability of the mattress support frame 61. Furthermore, the symmetrical arrangement of two sets of movable connectors and support rods 413 in this structure provides better balance.

[0041] refer to Figure 1 and Figure 3 In a preferred embodiment, the drive mechanism support 3 is located on the central axis of the bed frame 2, and the backrest drive mechanism 7 is connected to the side of the drive mechanism support 3. In this structure, the drive mechanism support 3, which bears the weight of the entire bed frame 2, is located on the central axis of the bed frame 2, while the backrest drive mechanism 7, used for adjusting the backrest, is connected to the side of the drive mechanism support 3. The layout is reasonable and the two mechanisms do not interfere with each other.
