Split back plate type waist support smart home bed

Abstract

A split-backboard lumbar support smart home bed, belonging to the home bed field, aims to solve problems such as poor lumbar support, discomfort when getting up, and unstable leg bending function in existing smart beds. The bed frame features a hip board, with one end hinged to the first and second backboards, and the other end hinged to the thigh and calf boards. A base frame is located within a notch in the first backboard, with a height-adjustable upper frame on top. When getting up, an electric backrest actuator rotates the backrest pivot, causing the second backboard to rise first, followed by the first. To adjust the lumbar support height, an electric lumbar support actuator pushes a sliding beam, deforming the X-shaped support arm and raising or lowering the upper frame. When bending the legs, an electric leg bending actuator pushes the calf board, working in conjunction with a pull rod to bend the legs. This bed alleviates lumbar discomfort, improves backrest comfort, and provides flexible and stable leg bending, meeting the needs of different rest or activity states.

Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization technology, and in particular to a split-back panel type smart home bed with lumbar support. Background Technology

[0002] As living standards continue to improve, people are increasingly pursuing comfort, leading to the emergence of smart furniture beds and home-based elderly care beds. Currently, most smart beds on the market offer only basic functions and fail to meet people's demands for a high-quality life: First, most have relatively soft mattresses, which can easily cause back pain with prolonged use; second, the downward force when raising the back creates discomfort, requiring manual adjustment and causing significant abdominal compression; third, ordinary smart bed mattresses are thick and soft, creating a large gap between the mattress and the bed surface when raising the back beyond 50 degrees, resulting in unsupported lower back pain after prolonged sitting.

[0003] To address the aforementioned issues, this utility model document proposes a split-back panel type lumbar support smart home bed. Utility Model Content

[0004] This utility model provides a split-back panel lumbar support smart home bed, which solves the problems of existing smart beds on the market, which are mostly functionally basic and do not meet people's requirements for a high-quality life: First, most of them have soft mattresses, which can easily cause back pain after prolonged use; second, when raising the back, there is a downward pushing force, which is uncomfortable and requires manual movement, and the abdomen is severely compressed; third, ordinary smart bed mattresses are too thick and soft, and when the back is raised more than 50 degrees, a large gap is formed between the mattress and the bed surface at the waist position, causing the waist to be suspended and easily causing back pain after sitting for a long time.

[0005] This utility model provides the following technical solution:

[0006] A split-back panel lumbar support smart home bed includes:

[0007] A bed frame, wherein a buttock board is fixedly installed in the center of the inner wall of the bed frame, a first back panel is hinged to one end of the buttock board, a second back panel is hinged to the other end of the first back panel, a thigh panel is hinged to the other end of the buttock board, and a calf panel is hinged to the other end of the thigh panel. A base frame is fixedly installed in the notch in the center of the first back panel, and a height-adjustable upper frame is installed directly above the base frame.

[0008] In one possible design, a backrest shaft is rotatably mounted on the inner wall of the bed frame via bearings, and two backrest arms are symmetrically fixed on the backrest shaft. Rollers are rotatably mounted on the inner wall of the backrest arms via pins, and a first slide rail for sliding connection of the corresponding rollers is fixedly provided at the bottom of the second back plate.

[0009] In one possible design, a backrest lifting electric push rod is hinged to the inner wall of the bed frame, a connecting plate is fixedly mounted on the backrest lifting shaft, and the other end of the backrest lifting electric push rod is hinged to the connecting plate.

[0010] In one possible design, a linear guide rail is fixedly installed on the top of the base frame, and a matching sliding beam is slidably installed on the top of the linear guide rail. The base frame and the upper frame are connected by two sets of hinged X-shaped support arms. One end of the top of the X-shaped support arm is hinged to the bottom of the upper frame and the other end is slidably connected to the second slide rail corresponding to the bottom of the upper frame. One end of the bottom of the X-shaped support arm is hinged to the top of the base frame and the other end is hinged to the side wall of the sliding beam.

[0011] In one possible design, a lumbar support electric push rod is installed on one side of the base frame, and the other end of the lumbar support electric push rod is connected to one side of the sliding beam.

[0012] In one possible design, two tie rods are symmetrically hinged to the bottom of the lower leg plate, and the other end of the tie rods is hinged to the inner wall of the bed frame. A leg-bending electric push rod is hinged to the inner wall of the bed frame, and the other end of the leg-bending electric push rod is hinged to the edge of the lower leg plate.

[0013] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0014] The working principle and usage process of this technical solution are as follows:

[0015] In practical use, the same soft pad is installed on the top of the second back panel, the first back panel, the buttocks panel, the thigh panel, and the calf panel. When it is necessary to adjust the height of the lumbar support, the electric lumbar support push rod can be activated wirelessly. The electric lumbar support push rod pushes the sliding beam to slide on the linear guide rail. Since the sliding beam is hinged to one end of the bottom of the X-shaped support arm, the other end of the bottom of the X-shaped support arm is hinged to the top of the base frame, one end of the top of the X-shaped support arm is hinged to the bottom of the upper frame, and the other end is slidably connected to the second slide rail corresponding to the bottom of the upper frame, the sliding of the sliding beam will cause the X-shaped support arm to deform. The deformation of the X-shaped support arm pushes the upper frame to rise or fall, thereby realizing the adjustment of the lumbar support height and supporting the waist.

[0016] During the lifting process, the electric lifting rod is activated wirelessly. The electric lifting rod pushes the connecting plate, which is fixed on the lifting shaft, thus causing the lifting shaft to rotate. Two lifting arms are symmetrically fixed on the lifting shaft. Rollers are rotatably mounted on the inner wall of the lifting arms via pins. The bottom of the second back panel is fixedly provided with a first slide rail. The rotation of the lifting shaft causes the rollers to slide in the first slide rail. The rollers first lift the second back panel at a certain angle (e.g., 30°). At this time, the second back panel, which is farther from the buttocks, rises first. The electric lifting rod continues to be pushed. As the lifting shaft rotates further, the rollers lift the second back panel and the first back panel together. The first back panel, which is closer to the buttocks, rises then, realizing the change of the back curvature and reducing the downward force generated during the lifting process.

[0017] During the leg bending process, the electric leg bending actuator is activated via wireless remote control. The electric leg bending actuator pushes the edge of the lower leg plate. Since there are two pull rods symmetrically hinged at the bottom of the lower leg plate, and the other end of the pull rod is hinged to the inner wall of the bed frame, and the upper leg plate is hinged to the lower leg plate, the push of the electric leg bending actuator causes the lower leg plate to rotate around the hinge point. At the same time, through the linkage of the pull rod, the lower leg plate is tilted and raised, ultimately realizing the leg bending function.

[0018] This utility model has the following beneficial effects:

[0019] This invention can alleviate lower back discomfort by providing lumbar support. The height of the lumbar support can be precisely controlled electronically, and the height can be flexibly adjusted according to the user's lower back condition and personal comfort preferences. This effectively supports the lower back, ensuring good support during long periods of sleep and preventing back pain caused by unsupported or uneven pressure. It also effectively reduces and releases spinal pressure, relieves lumbar pain, and improves sleep quality.

[0020] This invention improves backrest comfort. The product's backrest consists of two panels (a first backrest and a second backrest). When raising the back, the second backrest, which is farther from the buttocks, rises first, followed by the first backrest, which is closer to the buttocks. This combination makes the backrest's curvature more in line with the physiological curve of the human body when raising the back, greatly reducing the downward force generated during the raising process. This makes raising the back feel more natural and comfortable, avoiding the discomfort of being pushed downwards when raising the back in ordinary smart beds, as well as the problem of users having to move upwards themselves. It also reduces abdominal compression. Furthermore, when the backrest angle is large, the lumbar support can be controlled to rise upwards, supporting the lower back with the mattress and filling the gap between the mattress and the bed surface that causes the lower back to feel unsupported. This prevents lower back pain caused by prolonged backrest raising and provides users with more comprehensive lumbar support and protection.

[0021] In this invention, the leg-bending section is driven by a leg-bending motor to raise and lower the lower leg plate. The lower leg plate is connected to the bed frame by a pull rod, and the thigh plate is hinged to the lower leg plate. This achieves flexibility and stability of the leg-bending function, allowing users to easily adjust their leg posture according to their own needs to meet different rest or activity states, thereby improving the overall comfort and functionality of the bed.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0032] In one embodiment: Please refer to Figure 1-6 A type of home bed includes a bed frame 2, a backrest assembly, a hip board 9, a thigh board 10, a calf board 11, a backrest lifting mechanism, a lumbar support mechanism, and a leg bending mechanism, etc.

[0033] The bed frame 2 serves as the supporting frame for the entire bed, providing a base for the installation of other components. A hip board 9 is fixedly installed in the center of the inner wall of the bed frame 2. One end of the hip board 9 is hinged to the first back panel 7, and the other end of the first back panel 7 is hinged to the second back panel 6. The other end of the hip board 9 is hinged to the thigh panel 10, and the other end of the thigh panel 10 is hinged to the calf panel 11. The first back panel 7 has a notch in the center, and a base frame 17 is fixedly installed in the notch. A height-adjustable upper frame 8 is installed directly above the base frame 17. The second back panel 6, the first back panel 7, the hip board 9, the thigh panel 10, and the calf panel 11 are all covered with the same soft cushion, providing a comfortable sleeping surface for the user.

[0034] A backrest lifting mechanism is installed on the inner wall of the bed frame 2 to achieve the backrest lifting function. A backrest lifting shaft 3 is rotatably mounted on the inner wall of the bed frame 2 via bearings. Two backrest lifting arms 14 are symmetrically fixed on the backrest lifting shaft 3. Rollers 16 are rotatably mounted on the inner wall of the backrest lifting arms 14 via pins 5. A first slide rail 4 for sliding connection to the corresponding rollers 16 is fixedly provided at the bottom of the second backrest 6. A backrest lifting electric push rod 1 is hinged to the inner wall of the bed frame 2. A connecting plate 15 is fixedly mounted on the backrest lifting shaft 3. The other end of the backrest lifting electric push rod 1 is hinged to the connecting plate 15. During the backrest lifting process, the backrest lifting electric push rod is activated by wireless remote control. After push rod 1, the electric backrest push rod 1 pushes the connecting plate 15. Since the connecting plate 15 is fixed on the backrest shaft 3, it drives the backrest shaft 3 to rotate. The rotation of the backrest shaft 3 causes the roller 16 to slide in the first slide rail 4. The roller 16 first drives the second back plate 6 to rise at a certain angle. At this time, the second back plate 6, which is farther from the buttocks, rises first. Continue to push the electric backrest push rod 1. As the backrest shaft 3 rotates further, the roller 16 drives the second back plate 6 and the first back plate 7 to rise together. The first back plate 7, which is closer to the buttocks, rises again, realizing the change of the back curvature and reducing the downward pushing force generated during the backrest process.

[0035] A lumbar support mechanism is installed between the base frame 17 and the upper frame 8 to adjust the lumbar support height. A linear guide rail 18 is fixedly installed on the top of the base frame 17, and a matching sliding beam 19 is slidably installed on the top of the linear guide rail 18. The base frame 17 and the upper frame 8 are connected by two sets of hinged X-shaped support arms 21. One end of the top of the X-shaped support arm 21 is hinged to the bottom of the upper frame 8, and the other end is slidably connected to the second slide rail 22 corresponding to the bottom of the upper frame 8. One end of the bottom of the X-shaped support arm 21 is hinged to the top of the base frame 17, and the other end is connected to the sliding beam 19. The side wall is hinged, and a lumbar support electric push rod 20 is installed on one side of the base frame 17. The other end of the lumbar support electric push rod 20 is connected to one side of the sliding beam 19. When it is necessary to adjust the height of the lumbar support, the lumbar support electric push rod 20 is started by wireless remote control. The lumbar support electric push rod 20 pushes the sliding beam 19 to slide on the linear guide rail 18. The sliding of the sliding beam 19 causes the X-shaped support arm 21 to deform. The deformation of the X-shaped support arm 21 pushes the upper frame 8 to rise or fall, thereby realizing the adjustment of the lumbar position protrusion height and supporting the lumbar region.

[0036] This application can be used for split-back panel type home beds, or for other fields applicable to this application.

[0037] In another embodiment: a split-backboard lumbar support smart home bed, used in the field of home beds; please refer to... Figure 1-2 The leg-bending mechanism is used to realize the leg-bending function of the calf plate 11. Two pull rods 13 are symmetrically hinged to the bottom of the calf plate 11. The other end of the pull rod 13 is hinged to the inner wall of the bed frame 2. The leg-bending electric push rod 12 is hinged to the inner wall of the bed frame 2. The other end of the leg-bending electric push rod 12 is hinged to the edge of the calf plate 11. During the leg-bending process, after the leg-bending electric push rod 12 is started by wireless remote control, the leg-bending electric push rod 12 pushes the edge of the calf plate 11. The push of the leg-bending electric push rod 12 causes the calf plate 11 to rotate around the hinge point. At the same time, through the linkage of the pull rod 13, the calf plate 11 is tilted and raised, and finally the leg-bending function is realized. Users can easily adjust the leg posture according to their own needs to meet different rest or activity states.
