Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of nursing equipment, and particularly relates to a maglev rotating nursing bed. Background Art
[0002] With the aggravation of population aging, the proportion of the elderly population is rising continuously, and the social demand for elderly care is also increasing day by day. Since the elderly often suffer from various chronic diseases, such as cardiovascular diseases, cognitive impairments, etc., these diseases usually require professional nursing knowledge and nursing equipment to relieve the disease progression and improve the self-care ability of the elderly. Therefore, in both the medical and elderly care technical fields, in order to provide better nursing conditions for the elderly with inconvenient mobility and long-term bedridden, nursing beds are usually used for nursing to meet the various needs of the bedridden elderly in treatment, rehabilitation, and daily care, while reducing the work burden of nursing staff.
[0003] However, currently existing nursing beds can usually only adjust the height and angle of the bed body, but the angle of the bed body itself cannot be adjusted, which is not very convenient for users to get on and off the bed, making the operation relatively complex for some elderly people who do not need to be bedridden for a long time. And the internal mechanical structure of traditional nursing beds is very complex. Due to factors such as the friction of the mechanical structure or the operation of the motor, relatively large noises will be generated, which may cause problems such as irritability and sleep disorders for some users with poor sleep quality or neurasthenia. At the same time, traditional mechanical structure nursing beds are prone to mechanical failures during use, affecting the smoothness of the nursing bed, causing the nursing bed to shake or be unstable during use, and there are also certain safety hazards. Summary of the Invention
[0004] The present invention provides a maglev nursing bed, which can not only solve the problems in the background art, but also make the pressure distribution on each part of the user's body more uniform after lying down, reducing local pressure concentration on the body, especially for long-term bedridden patients, greatly improving the comfort of lying in bed.
[0005] The above technical object of the present invention is achieved through the following technical solutions: A maglev rotating nursing bed includes a bed body base and a maglev rotating body. An electromagnetic float is arranged inside the maglev rotating body. A fixed permanent magnet and an adjusting electromagnet are also arranged on the bed body base. By adjusting the real-time current of the adjusting electromagnet, dynamic control of the levitation force can be realized, so that the maglev rotating body can be electromagnetically levitated above the bed body base. A bed body support is arranged on the maglev rotating body, and the maglev rotating body can drive the bed body support to rotate together. A lifting and moving mechanism is also arranged on the bed body base, and the lifting and moving mechanism can adjust the overall height of the nursing bed.
[0006] Preferably, the maglev rotating body is of a groove structure, and a rotating body mounting portion is provided at the top. The bed body bracket is fixedly installed above the rotating body mounting portion. The electromagnetic floats on the maglev rotating body are arranged in a circumferential structure and are fixedly embedded inside the maglev rotating body. The maglev rotating body is fixedly installed with the bed body bracket, and the electromagnetic floats are installed inside the maglev rotating body by embedding. Therefore, the suspension of the maglev rotating body can drive the bed body to suspend together. When the user lies on the nursing bed, the pressure distribution on various parts of the body is relatively uniform, which can reduce the excessive concentration of local pressure on the body. Especially for long-term bedridden users, it can effectively prevent complications such as bedsores and greatly improve the comfort of lying in bed.
[0007] Preferably, a circular rotating guide rail is fixedly installed at the center position of the bottom of the maglev rotating body. Two arc-shaped rotating permanent magnets are symmetrically arranged on the inner wall of the rotating guide rail, and the magnetic poles of the two rotating permanent magnets are opposite. The maglev rotating body can not only drive the bed body bracket to suspend, but also drive it to rotate together. The rotating guide rail at the center of the maglev rotating body can ensure that the bed body rotates along a specified route during the rotation process. The two rotating permanent magnets with opposite magnetic poles symmetrically arranged on the inner wall of the rotating guide rail can rotate when the stator is energized. The nursing bed uses electromagnetic suspension rotation technology, avoiding the use of traditional mechanical rotation structures, reducing mechanical friction, making the noise generated during the use of the nursing bed extremely low, achieving non-contact, low-friction, and noiseless rotation, reducing the discomfort caused by mechanical vibration, providing a quieter and more comfortable rest environment for users, and being beneficial to the sleep and rehabilitation of patients.
[0008] Preferably, the fixed permanent magnet on the bed base is designed in a ring structure. The ring size of the fixed permanent magnet is similar to the circumferential size of the circumferential arrangement of the electromagnetic floats, and the magnetic poles of the fixed permanent magnet are the same as those of the electromagnetic floats. The adjustable electromagnets are arranged in a circular array inside the ring of the fixed permanent magnet. Each adjustable electromagnet is a wound coil. By adjusting the magnitude and direction of the current in the adjustable electromagnet, the height position of the electromagnetic float can be adjusted in real time. A suspension Hall sensor is also arranged inside the ring of the fixed permanent magnet. The magnetic poles of the ring-shaped fixed permanent magnet on the bed base are the same as those of the electromagnetic floats on the magnetic levitation rotating body. The fixed permanent magnet can provide an upward repulsive force to the electromagnetic floats. A number of adjustable electromagnets are also arranged in a circular array inside the ring of the fixed permanent magnet. The magnitude of the current in the coil of the adjustable electromagnet is adjustable. By adjusting the magnitude of the current, the magnitude of the magnetic force provided by the adjustable electromagnet can be controlled. The repulsive forces provided by the fixed permanent magnet and the adjustable electromagnets enable the electromagnetic floats to drive the magnetic levitation rotating body and the bed support above it to levitate together. A suspension Hall sensor is also arranged on the bed base, which can detect the position of the electromagnetic float in real time. The magnitude of the current can be adjusted in real time according to the pressure of the user of the nursing bed to adjust the height position of the electromagnetic float, so that the magnetic levitation can always provide a stable supporting force.
[0009] Preferably, a stator shaft is fixedly installed at the center position of the bed base. Three groups of electromagnetic stators are arranged on the stator shaft. Each group of electromagnetic stators is wound with a coil. By changing the current direction of each group of coils, the magnetic poles of each group of electromagnetic stators can be adjusted. A rotation Hall sensor is also arranged at the position of the bed base corresponding to the electromagnetic stator. The stator shaft at the center of the bed base is fixedly installed, and each group of electromagnetic stators on the stator shaft is wound with a coil. When the coils of the electromagnetic stators are energized, each group of electromagnetic stators can be regarded as an electromagnet with two magnetic poles. Due to the principle of opposite poles attracting and like poles repelling, the rotating permanent magnet on the magnetic levitation rotating body will be attracted to the opposite pole position of the electromagnetic stator. At this time, the current in the coil of the current group of electromagnetic stators is cut off, and the coil of the next group of electromagnetic stators is energized. The rotating permanent magnet on the magnetic levitation rotating body will continue to be attracted and rotate. Then, the current in the second group of coils is cut off, and the coil of the third group of coils is energized. The rotating permanent magnet will continue to rotate to the position of the third group of coils. When the current in the third group of coils is cut off, the coil of the first group of coils is energized again. However, since the polarity of the magnetic poles of the rotating permanent magnet is different after one rotation, the current direction of the first group of coils is changed, and the rotating permanent magnet can continue to be attracted to rotate, realizing the electromagnetic rotation of the magnetic levitation rotating body. Since only one group of coils is energized at a time, the rotation speed can be adjusted by controlling the magnitude of the current, making the rotation smoother. A rotation Hall sensor is arranged at the position of the bed base corresponding to the electromagnetic stator, which can detect the precise position of the magnetic poles of the rotating permanent magnet in real time, so as to adjust the on-off and current direction of the coil in real time to ensure smooth rotation.
[0010] Preferably, the bed body support includes a back support, a waist support, a thigh support, a calf support and a foot support. The foot support is fixedly installed on the bed body base.

Bed body armrests are provided on both sides of the back support close to the human arm. A lifting mechanism is also fixedly provided at the bottom of the waist support; the bed body support is composed of multiple support hinges. The lifting mechanism below the bed body support can adjust the bed body support at different angles. Long-term bedridden users are prone to physical fatigue and discomfort. The lifting mechanism can help users easily change their lying postures, such as lifting to a supine position, a semi-recumbent position or a sitting position, so that different parts of the body bear pressure in turn, reducing the over-concentration of local pressure, improving the comfort of users lying in bed, and at the same time enabling users to interact with the surrounding environment more conveniently, increasing the autonomy and comfort of users' lives, and enhancing the psychological state and quality of life of users.
[0011] Preferably, the lifting mechanism is installed on the maglev rotating body and includes a back lifting mechanism and a leg lifting mechanism. A back electric push rod is provided on the back lifting mechanism and is hinged to a back lifting shaft. A back lifting arm is fixedly connected to the back lifting shaft and is hinged to the back support. A leg electric push rod is provided on the leg lifting mechanism and is hinged to a leg lifting shaft. A leg lifting arm is fixedly connected to the leg lifting shaft and is hinged to the calf support. The supine angle of the bed body can be changed through the lifting mechanism. The back lifting mechanism drives the back lifting arm on the back lifting shaft to rotate through the back electric push rod, so that the back support is lifted upward, allowing users to achieve a semi-recumbent or sitting posture. The leg lifting mechanism drives the leg lifting arm on the leg lifting shaft to rotate through the leg electric push rod, causing the leg support to be lifted upward, realizing the movement of the user's legs, contributing to the blood circulation of the user's legs, and can cooperate well with rehabilitation training.
[0012] Preferably, a support frame is provided at a position on the bed body base close to the foot support, and the foot support is fixedly installed on the support frame; a second buffer pad is installed at a position on the support frame corresponding to the calf support, and a first buffer pad is installed at a position on the bed body base corresponding to the back support; a first buffer pad and a second buffer pad are provided on the bed body base. When the nursing bed encounters a circuit failure or a power outage, the buffer pads can well cope with the situation of suspension failure and prevent users from being bumped due to suspension failure.
[0013] Preferably, a mattress is provided on the bed body support. Among them, the mattresses corresponding to the positions of the calf support and the foot support are independent, and the mattresses in the remaining parts are integral. Massage airbags are provided inside the mattress. The massage airbags are communicated with an air pump through air pipes, and a control motor is also provided on the air pump. The control motor outputs signals to control the gas in the air pump to enter or exit the massage airbags through the air pipes, enabling the massage airbags to perform a massage function on the body. For long-term bedridden users, the blood circulation of the body is relatively slow. The massage airbags can perform periodic pressing and relaxation on the human body, promoting the acceleration of blood circulation, reducing the risk of blood circulation disorder diseases. At the same time, it can also relax the muscles, help the user slowly recover the muscle state, and can also change the pressure between the body and the mattress, avoiding excessive pressure on the body for a long time, thus effectively reducing the incidence rate of bedsore and other diseases, and at the same time assisting in regulating the body function and helping the user recover better health.
[0014] Preferably, the lifting and moving mechanism is arranged under the bed body base, including two symmetrically arranged telescopic connecting rods. The telescopic connecting rods are hinged to the bed body base and arranged on the lifting brackets. The lifting and moving mechanism is provided with a lifting electric cylinder to provide lifting force. Moving wheels for moving the nursing bed are also provided at the four corners of the lifting brackets. The lifting and moving mechanism can adjust the height of the bed body to meet the needs of users for the height of the sleeping bed. At the same time, it can also make it more convenient for medical staff to carry out medical care work on the bedridden users, without excessive movement of the body of the bedridden person, reducing the pain or inconvenience caused by the body movement of the bedridden person, and also improving the work efficiency of medical staff.

Those skilled in the art can make modifications to these embodiments without creative contributions after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
[0019] The present invention will be described in detail below with reference to the accompanying drawings in embodiments.
[0020] Embodiment
[0021] According to Figures 1 to 4 As shown, a maglev rotating nursing bed includes a bed base 1 and a maglev rotating body 2. An electromagnetic float 21 is arranged inside the maglev rotating body 2. A fixed permanent magnet 111 and an adjustable electromagnet 112 are also arranged on the bed base 1. By adjusting the real-time current of the adjustable electromagnet 112, dynamic control of the suspension force can be achieved, so that the maglev rotating body 2 can be electromagnetically suspended above the bed base 1; a bed support 3 is arranged on the maglev rotating body 2, and the maglev rotating body 2 can drive the bed support 3 to rotate together. A lifting and moving mechanism 4 is also arranged on the bed base 1, and the lifting and moving mechanism 4 can adjust the overall height and position of the nursing bed.
[0022] According to Figure 2 、 Figure 3As shown, the maglev rotating body 2 has a groove structure, and a rotating body mounting part 24 is provided at the top. The bed body support 3 is fixedly installed on the rotating body mounting part 24. The electromagnetic floats 21 on the maglev rotating body 2 are arranged in a circumferential pattern and are fixedly embedded inside the maglev rotating body 2. The maglev rotating body 2 is fixedly installed with the bed body support 3, and the electromagnetic floats 21 are installed by embedding inside the maglev rotating body 2. Therefore, the suspension of the maglev rotating body 2 can drive the bed body support 3 to suspend together. When the user lies on the nursing bed, the pressure distribution on various parts of the body is relatively uniform, which can reduce the excessive concentration of local pressure on the body. Especially for long-term bedridden users, it can effectively prevent complications such as bedsores and greatly improve the comfort of lying in bed.
[0023] According to Figure 2 、 Figure 4 As shown, a ring-shaped rotating guide rail 22 is also fixedly installed at the central position of the bottom of the maglev rotating body 2. Two arc-shaped rotating permanent magnets 23 are symmetrically arranged on the inner wall of the rotating guide rail 22, and the magnetic poles of the two rotating permanent magnets 23 are opposite. The maglev rotating body 2 can not only drive the bed body support 3 to suspend, but also drive it to rotate together. The rotating guide rail 22 at the center of the maglev rotating body 2 can ensure that the bed body rotates along a specified route during the rotation process. The two rotating permanent magnets 23 with opposite magnetic poles symmetrically arranged on the inner wall of the rotating guide rail 22 can rotate when the stator is energized. The nursing bed uses electromagnetic suspension rotation technology, avoiding the use of traditional mechanical rotation structures, reducing mechanical friction, making the noise generated during the use of the nursing bed extremely low, achieving contactless, low-friction, and noise-free rotation, reducing the discomfort caused by mechanical vibration, providing a quieter and more comfortable rest environment for users, and being beneficial to the sleep and rehabilitation of patients.
[0024] According to Figure 2 、 Figure 3As shown, the fixed permanent magnet 111 on the bed base 1 is designed in a ring structure. The ring size of the fixed permanent magnet 111 is similar to the circumferential size of the circumferential arrangement of the electromagnetic floats 21. The magnetic poles of the fixed permanent magnet 111 are the same as those of the electromagnetic floats 21. The adjusting electromagnets 112 are arranged in a circumferential array inside the ring of the fixed permanent magnet 111. Each adjusting electromagnet 112 is a wound coil. By adjusting the magnitude and direction of the current in the adjusting electromagnet 112, the height position of the electromagnetic float 21 can be adjusted in real time. A suspension Hall sensor 113 is also arranged inside the ring of the fixed permanent magnet 111. The magnetic poles of the ring-shaped fixed permanent magnet 111 on the bed base 1 are the same as those of the electromagnetic floats 21 on the magnetic levitation rotating body 2. The fixed permanent magnet 111 can provide an upward repulsive force to the electromagnetic float 21. A number of adjusting electromagnets 112 are also arranged in a circumferential array inside the ring of the fixed permanent magnet 111. The magnitude of the current in the coil on the adjusting electromagnet 112 is adjustable. By adjusting the magnitude of the current, the magnitude of the magnetic force provided by the adjusting electromagnet 112 can be controlled. The repulsive forces provided by the fixed permanent magnet 111 and the adjusting electromagnets 112 enable the electromagnetic float 21 to drive the magnetic levitation rotating body 2 and the bed support 3 above it to float together. A suspension Hall sensor 113 is also arranged on the bed base 1, which can detect the position of the electromagnetic float 21 in real time. The magnitude of the current can be adjusted in real time according to the pressure of the user of the nursing bed to adjust the height position of the electromagnetic float 21, so that the magnetic levitation can always provide a stable supporting force.
[0025] According to Figure 2 、 Figure 4As shown, a stator shaft 121 is fixedly installed at the central position of the bed base 1. There are three groups of electromagnetic stators 122 arranged on the stator shaft 121. Each group of electromagnetic stators 122 is wound with a coil. By changing the current direction of each group of coils, the magnetic poles of each group of electromagnetic stators 122 can be adjusted. A rotary Hall sensor 123 is also arranged at the position of the bed base 1 corresponding to the electromagnetic stator 122; the stator shaft 121 at the center of the bed base 1 is fixedly installed, and each group of electromagnetic stators 122 on the stator shaft 121 is wound with a coil. When the coils of the electromagnetic stators 122 are energized, each group of electromagnetic stators 122 can be regarded as an electromagnet with two magnetic poles. Due to the principle of opposite poles attracting and like poles repelling, the rotary permanent magnet 23 on the magnetic levitation rotating body 2 will be attracted to the opposite pole position of the electromagnetic stator 122. At this time, the current in the coil of the current group of electromagnetic stators 122 is cut off, and the coil of the next group of electromagnetic stators 122 is energized. The rotary permanent magnet 23 on the magnetic levitation rotating body 2 will continue to be attracted and rotate. Then, the current of the second group of coils is continuously cut off, and the third group of coils is energized. The rotary permanent magnet 23 will continue to rotate to the position of the third group of coils. When the current of the third group of coils is cut off, the first group of coils is energized again. However, due to the different polarities of the magnetic poles of the rotary permanent magnet 23 after rotating one circle, the current direction of the first group of coils is changed, and the rotary permanent magnet 23 can be continuously attracted to rotate, realizing the electromagnetic rotation of the magnetic levitation rotating body 2. Since only one group of coils is energized at a time, the rotation speed can be adjusted by controlling the current magnitude, making the rotation smoother; a rotary Hall sensor 123 is arranged at the position of the bed base 1 corresponding to the electromagnetic stator 122, which can detect the precise position of the magnetic pole of the rotary permanent magnet 23 in real time, so as to adjust the on / off of the coil and the current direction in real time to ensure smooth rotation.
