Description

Technical Field

[0001] The present invention relates to a patient care bed, and more particularly to a multifunctional toilet care bed. Background Art

[0002] With the accelerating aging of the population, an increasing number of patients require long-term bed rest for treatment and rehabilitation. Due to disability and other factors, bedridden patients often suffer from inability to urinate or defecate independently, which makes daily care difficult and inconvenient. With technological advancements, existing nursing beds have become increasingly versatile. Many beds not only provide back-lifting, leg-flexing, and turning functions, but also feature toilets. This increased functionality has led to increasingly complex and bulky structures, significantly increasing their cost and bulk, compromising their flexibility.

[0003] Therefore, how to ensure the multifunctionality of the nursing bed while ensuring that the nursing bed has a compact structure that is convenient for flexible turnover has become one of the research hotspots in this field. Summary of the Invention

[0004] 1. Technical problem to be solved by the invention

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of existing nursing beds and provide a multifunctional nursing bed with toilet to solve the problems of existing multifunctional nursing beds, such as complex and bulky structures and inconvenient turnover. The technical solution of the present invention is adopted, and the structure of functional mechanisms such as turning over and toileting is optimized through clever structural design, making the overall structure of the nursing bed more compact. While ensuring the functionality of the nursing bed, the nursing bed is made lighter and more convenient for flexible turnover. At the same time, its turning mechanism uses a single turning electric push rod to stably control the left and right flipping of the mattress support assembly. The structure is simple and compact, the space is small, and the turning movement is stable and reliable. The toilet mechanism adopts a linkage design of the toilet hole support assembly and the toilet bowl assembly, and the upward flipping action of the toilet bowl assembly lags behind the downward flipping action of the toilet hole support assembly, making the action switching of the toilet mechanism more stable and reliable. Only a single toilet flip electric push rod is required to complete the switching control. The overall structure is simple and compact.

DETAILED DESCRIPTION

[0044] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0045] [Example]

[0046] Combine Figure 1As shown, a multifunctional toilet care bed of this embodiment includes a bed frame 1, a turning mechanism 2, a mattress support assembly 3, a toilet mechanism 4, a back lifting mechanism 5 and a leg bending mechanism 6. The mattress support assembly 3 is supported on the bed frame 1, and the turning mechanism 2 is arranged on the bed frame 1 and is located below the mattress support assembly 3, and is used to drive the mattress support assembly 3 to flip sideways in the left and right directions; the toilet mechanism 4 is arranged in the middle of the bed frame 1, and the back lifting mechanism 5 and the leg bending mechanism 6 are respectively arranged at the front and rear of the bed frame 1.

[0047] in:

[0048] like Figures 2 to 4 As shown, the above-mentioned turning mechanism 2 includes a turning electric push rod 2-1, a turning shaft 2-2, a turning support rod 2-3, a push-up connecting rod 2-4 and a bracket hinge seat 2-5. The turning shaft 2-2 is arranged in the middle of the bed frame 1 and rotates along the front and rear directions of the nursing bed. One end of the turning electric push rod 2-1 is hinged to the bed frame 1, and the other end is hinged to the turning swing arm 2-2a on the turning shaft 2-2. The turning shaft 2-2 is driven to rotate by the telescopic movement of the turning electric push rod 2-1; a turning support rod 2-3 is provided on each side of the turning shaft 2-2, and Two turning struts 2-3, one end near the center of the nursing bed, are pivotally connected to the bed frame 1. The other ends of the turning struts 2-3 are hinged to the corresponding side of the mattress support assembly 3 via push-up links 2-4. An eccentric push plate 2-2b is also fixed to the turning shaft 2-2, positioned below the turning struts 2-3. When the turning electric push rod 2-1 rotates the turning shaft 2-2 to one side, the eccentric push plate 2-2b swings upward, pushing the turning strut 2-3 on the corresponding side, which in turn drives the mattress support assembly 3 to the opposite side via the corresponding push-up links 2-4. The turning mechanism 2 utilizes a single turning electric push rod 2-1 to stably control the left and right tilting of the mattress support assembly 3. This results in a simple and compact structure, small footprint, and stable and reliable turning motion. Specifically, the turning struts 2-3 are coaxially rotatably mounted on the turning shaft 2-2, and the eccentric push plate 2-2b is fixed to the turning shaft 2-2. When the patient rolls to one side, the turning shaft 2-2 rotates, driving the eccentric push plate 2-2b to rotate. The eccentric push plate 2-2b pushes the turning struts 2-3 on the corresponding side upward. The turning struts 2-3 push up the corresponding mattress support assembly 3 via the push-up connecting rod 2-4, thereby achieving the sideways movement of the mattress support assembly 3. At this time, the turning struts 2-3 on the other side are free, and the mattress support assembly 3 on the other side is in a horizontal position. Conversely, when the patient rolls to the other side, the eccentric push plate 2-2b pushes the turning struts 2-3 on the other side. The already raised turning struts 2-3 on the other side lose the thrust of the eccentric push plate 2-2b and return to a horizontal position under the action of the mattress support assembly 3 and the patient's weight.

[0049] Further, refer to Figure 3 and Figure 4As shown, in this embodiment, the mattress support assembly 3 includes a center bracket and lateral brackets hinged to the left and right sides of the center bracket. The outer ends of the lateral brackets are hingedly connected to connecting plates 2-8, which are equipped with sliders 2-7. Sliders 2-7 slide on guide rods 2-6, which are mounted horizontally on the bed frame 1 along the width of the nursing bed. The guide rods 2-6 are also sleeved with return springs 2-9, which compress against the sliders 2-7 on the corresponding sides. This design allows the outer ends of the lateral brackets to slide horizontally relative to the guide rods during turning, ensuring the overall stability of the mattress support assembly and improving safety. To reduce friction during turning, side rollers 3-6 are also installed on the outer ends of the lateral brackets, which can roll sideways on the bed frame 1. This reduces friction and noise between the lateral brackets and the bed frame during turning.

[0050] like Figures 5 to 7 As shown, in this embodiment, the toilet mechanism 4 includes a mounting frame 4-1, a toilet hole support assembly, a toilet bowl assembly, a toilet flip electric push rod 4-6 and a linkage rod 4-11. The mounting frame 4-1 is fixed to the middle part of the bed frame 1. The middle part of the mounting frame 4-1 has a toilet hole. The toilet hole support assembly is rotatably arranged on one side of the lower part of the mounting frame 4-1. The toilet bowl assembly is arranged on the other side of the lower part of the mounting frame 4-1 through a parallel four-bar linkage. One end of the toilet flip electric push rod 4-6 is hinged to the toilet hole support assembly, and the other end is hinged to the mounting frame 4-1, which is used to drive the toilet hole support assembly to flip and switch between the toilet hole position and the exit position; the linkage rod 4-11 connects the toilet hole support assembly and the toilet bowl assembly, and is used to pull the toilet bowl assembly to translate and flip into the toilet hole when the toilet hole support assembly switches from the toilet hole position to the exit position; the linkage rod 4-11 also has a hysteresis linkage structure, which is used to make the upward flipping action of the toilet bowl assembly lag behind the downward flipping action of the toilet hole support assembly. Thus, when the toilet is not in use, the toilet seat flip electric push rod 4-6 drives the toilet hole support assembly to flip toward the toilet hole, providing support for the toilet hole. When the toilet hole is needed, the toilet seat flip electric push rod 4-6 drives the toilet hole support assembly to flip downward. Due to the hysteresis linkage structure of the linkage pull rod 4-11, the toilet hole support assembly will not flip upward until it has flipped downward a certain angle. Since the toilet bowl assembly adopts a parallelogram linkage design, the toilet bowl can maintain horizontal movement into the toilet hole. The use of the above-mentioned toilet seat mechanism 4 makes the action switching of the toilet seat mechanism 4 more stable and reliable. Only one toilet seat flip electric push rod 4-6 is required to complete the switching control, and the overall structure is simple and compact.

[0051] catch Figures 5 to 7As shown, specifically in this embodiment, the above-mentioned toilet hole support assembly includes a rotating shaft 4-2, a support frame 4-3 and a toilet hole support block 4-5. The rotating shaft 4-2 is rotatably mounted on the mounting frame 4-1, the support frame 4-3 is fixed on the rotating shaft 4-2, the toilet hole support block 4-5 is fixed on the support frame 4-3, and the toilet flip electric push rod 4-6 is hinged to the hinge seat 4-2a on the rotating shaft 4-2; the toilet flip electric push rod 4-6 telescopic movement drives the rotating shaft 4-2 to rotate, and then drives the support frame 4-3 thereon to flip, so that the toilet hole is blocked by the toilet hole support block 4-5. The toilet assembly includes a first upward flip link 4-7, a second upward flip link 4-8, a toilet frame 4-9 and a toilet 4-10. One end of the first upward flip link 4-7 and the second upward flip link 4-8 are respectively hinged to the bottom of the mounting frame 4-1, and the other ends of the first upward flip link 4-7 and the second upward flip link 4-8 are respectively hinged to the toilet frame 4-9. The mounting frame 4-1, the first upward flip link 4-7, the toilet frame 4-9 and the second upward flip link 4-8 constitute a parallel four-bar linkage mechanism, and the toilet 4-10 is fixed on the toilet frame 4-9. The use of the parallel four-bar linkage mechanism can keep the toilet 4-10 in a horizontal state at all times. One end of the linkage rod 4-11 is hinged to the second upward link 4-8, and the other end of the linkage rod 4-11 has a hysteresis slot. The support frame 4-3 is provided with a sliding pin 4-4a that can slide in the above-mentioned hysteresis slot. The idle sliding stroke of the sliding pin 4-4a in the hysteresis slot constitutes the above-mentioned hysteresis linkage structure. The sliding pin 4-4a can be fixed to the connecting rod 4-4 of the support frame 4-3. Figure 5 As shown, when the toilet hole support block 4-5 flips downward from the toilet hole position, the sliding pin 4-4a also makes an arc motion around the rotating shaft 4-2, and the sliding pin 4-4a slides in the hysteresis chute. At this time, the linkage pull rod 4-11 does not generate a pulling force on the second upward turning link 4-8, and the toilet bowl 4-10 remains in the bottom position (as shown in FIG. Figure 6 When the sliding pin 4-4a moves to the end of the hysteresis chute, the sliding pin 4-4a generates a pulling force on the linkage rod 4-11, and the linkage rod 4-11 pulls the second upward link 4-8, causing the parallel four-bar linkage to flip upward, thereby moving the toilet bowl 4-10 to the toilet hole position, forming Figure 7 Similarly, when the toilet is not in use, the toilet flip electric push rod 4-6 drives the toilet hole support block 4-5 to flip upward, and at the same time the toilet 4-10 moves downward under the action of gravity. When the toilet 4-10 moves to the bottom, the toilet 4-10 no longer moves, and at this time the sliding pin 4-4a moves in the hysteresis chute.

[0052] In order to facilitate the length adjustment of the linkage rod 4-11, the linkage rod 4-11 includes a fixed rod 4-11a, an adjustable rod 4-11b and a slide rod 4-11c. The fixed rod 4-11a is connected to the slide rod 4-11c through the adjustable rod 4-11b. The adjustable rod 4-11b can be used to adjust the overall length of the linkage rod 4-11, that is, to change the distance between the end of the lagging slide of the slide rod 4-11c and the end of the fixed rod 4-11a, which can facilitate the adjustment of the matching relationship between the toilet bowl 4-10 and the toilet hole support block 4-5.

[0053] like Figure 8 and Figure 9 As shown, in this embodiment, the back-lifting mechanism 5 includes a back-lifting and flipping frame 5-1, a back-lifting shaft 5-2, and a back-lifting electric push rod 5-3. The back-lifting and flipping frame 5-1 is fixed to the back-lifting shaft 5-2, and the two ends of the back-lifting shaft 5-2 are respectively rotatably mounted on the bed frame 1. One end of the back-lifting electric push rod 5-3 is hinged to the bed frame 1, and the other end is hinged to the back-lifting swing arm 5-2a on the back-lifting shaft 5-2. By controlling the telescopic movement of the back-lifting electric push rod 5-3, the back-lifting and flipping frame 5-1 can be controlled to flip around the back-lifting shaft 5-2. The mattress support assembly 3 also has a back support and a hip support hinged together. The back-lifting and flipping frame 5-1 is located below the back support. The lower side of the back support also has a mattress support roller 3-5 that can roll relative to the back-lifting and flipping frame 5-1. The back-lifting action is stable and reliable, and the friction and noise generated by the back-lifting action are small. Specifically, in this embodiment, the mattress support assembly 3 includes a middle back support 3-1, back side supports 3-2, a middle hip support 3-3, and hip side supports 3-4. The middle back support 3-1 is hingedly connected to the back side supports 3-2 on either side, and the middle hip support 3-3 is hingedly connected to the hip side supports 3-4 on either side. The middle back support 3-1 is hingedly connected to the middle hip support 3-3, and the back side supports 3-2 are hingedly connected to the corresponding hip side supports 3-4. Mattress support rollers 3-5 are located at the bottom of the middle back support 3-1 and the back side supports 3-2, respectively. Side rollers 3-6 are located on the back side supports 3-2 and the hip side supports 3-4, respectively. The mattress support rollers 3-5 roll in the front-to-back direction of the nursing bed, while the side rollers 3-6 roll in the left-to-right direction.

[0056] The multifunctional nursing bed with toilet seat, designed with clever structural design to optimize the structures of its turning and toilet functions, makes the overall structure of the bed more compact. While ensuring its functionality, the bed is also lighter and more flexible for use. Furthermore, its turning mechanism utilizes a single electric push rod to stably control the left and right tilting of the mattress support assembly, resulting in a simple and compact structure, small footprint, and stable and reliable turning motion. The toilet seat utilizes a linkage design between the toilet hole support assembly and the commode assembly, with the upward tilt of the commode assembly lagging behind the downward tilt of the toilet hole support assembly. This makes the toilet seat mechanism's switching more stable and reliable, requiring only a single electric push rod to complete the switching control. The overall structure is simple and compact.
