In addition, a plurality of annular slots 802d are densely arranged on the inner wall of the inner cylinder 802 a. When the magnetic latch mechanism 811 is powered on, the spring 811b is compressed by the attraction between the magnetic field generated by the electromagnetic coil 811a and the permanent magnet 811c, and the latch 811d is retracted from the annular notch 811d, thereby releasing the restriction on the movement of the inner cylinder 802 a; when the magnetic latch 811 is powered off, the spring 811b pushes the latch 811d into the annular slot 802d by its restoring force, so as to block or support the inner cylinder 802a in time and effectively prevent the falling risk caused by power failure.
The levitating magnet 807 is located at the center of the bottom of the inner cylinder 802a, and four positioning through holes 807a are uniformly formed in the levitating magnet 807 at equal intervals, wherein a circumferential angle obtained after any two adjacent positioning through holes 807a are connected with the center of the levitating magnet 807 is a right angle.

A guide rope 806 passes through the positioning through hole 807a, one end of the guide rope 806 is connected to the lower edge of the bed support rod 2, and the other end of the guide rope 806 vertically passes through the smooth positioning through hole 807a, enters the interior of the first support spring 804 and is fixed on the bottom of the upper space 801a of the base. The guide action of the guide cable 806 prevents the inner cylinder 802a from shifting vertically and rotating horizontally during the up-and-down movement.
Preferably, a magnetic induction force is generated between the levitation magnet 807 and the energized electromagnetic coil 808 to drive the levitation magnet 807 to move upward, at this time, the pressure borne by the levitation supporting device 8 is borne by the elastic force of the first supporting spring 804, the elastic force of the second supporting spring 805 and the magnetic induction force, and the first supporting spring 804 and the second supporting spring 805 provide supporting force, and the magnetic induction force is smaller and plays a role in assisting lifting and controlling, so that the magnetic levitation device can be realized without using a large current and a large magnetic field intensity, and has the advantages of energy saving, consumption reduction, small radiation and the like.
As shown in fig. 5, the elastic support 803 has a dome shape, the bottom of which is connected to the upper end of the inner cylinder 802a, and the dome surface of which is covered with an elastic insulator 803a for buffering and preventing electric leakage. In addition, a vibration massage device 803b is further disposed inside the elastic support 803, and positioning cushions 803c for positioning and cushioning are disposed at upper and lower portions of the vibration massage device 803b to prevent the vibration massage device 803b from moving and having too strong impact force during vibration, so that a user can feel a more comfortable massage effect.
Preferably, a pressure sensor 809 is further arranged inside the end part of the elastic supporting body 803, so as to monitor the pressure on the current suspended supporting device 8 in real time; the device also comprises a distance sensor 810 arranged right below the vertical intersection point of any two bed surface support rod pieces 2, and the distance sensor is used for monitoring the distance from the vertical intersection point of any two bed surface support rod pieces 2 to the central point of the suspended magnet 807 below in real time, and meanwhile, the distance is also equal to the first support spring 804 (the elastic coefficient K)1) And a second supporting spring 805 (K)2) Further, the pressures to which the first supporting spring 804 and the second supporting spring 805 are respectively subjected can be calculated under the condition that the elastic coefficients are known.
As can be seen from the above, the pressure F applied to the end of the elastic support 803 can be fully calculated according to the spring deformation Δ X detected by the distance sensor 810, and the specific calculation formula is as follows:
F＝K1ΔX+K2ΔX；
further, it can be obtained that the pressure F' detected by the pressure sensor 809 is ideally equal to the F, but actually has a deviation, but if the deviation is large, a corresponding problem occurs, and specifically, by comparing the magnitudes of the F and F, the following can be concluded: when F' > 1.2F indicates that the first supporting spring 804 and/or the second supporting spring 805 have serious fatigue phenomena to cause insufficient elasticity, the first supporting spring 804 and/or the second supporting spring 805 which have fatigue phenomena need to be replaced in time; when F' < 0.8F, the value measured by the pressure sensor 809 is cheap, and the pressure sensor 809 needs to be repaired or replaced in time. In summary, the defective components (the first supporting spring 804, the second supporting spring 805, and the pressure sensor 809) can be indirectly known by comparing the magnitude of the F value and the F' value.
As shown in fig. 4, preferably, the bed support bar 2 is provided with a hoop 814 at the strip-shaped opening 802c, the left and right sides of the hoop 814 are provided with cylindrical rollers 815, and two shallow grooves 813 with smooth surfaces are further formed on two inner sides in the vertical direction of the strip-shaped opening 802c, so as to further realize that the cylindrical rollers 815 roll up and down in the shallow grooves 813. More preferably, the surface layers of the cylindrical rollers 815 and the shallow grooves 813 are made of smooth ceramic materials, so that the rolling resistance is reduced to the maximum extent.
More preferably, the sleeve 802, the first partition plate 3 and the second partition plate 9 are preferably made of a non-metallic material that does not affect the magnetic field, such as a wooden material, a bamboo material, a ceramic material or an ABS engineering plastic, etc.
The touch screen control unit 7 is used for realizing accurate control over the plurality of suspension supporting devices 8, when a user lies on a bed surface formed by the plurality of suspension supporting devices 8, the user can further realize accurate adjustment of the sleeping posture by controlling the touch screen control unit 7, and meanwhile, the user can also set the sleeping posture information in a self-defined manner and store the information in the memory storage module so as to be directly called next time. The touch screen control unit 7 is fixed by using the telescopic folding rod 6 which can be freely turned, so that a user can conveniently operate at any position of the head of the bed. The touch screen control unit 7 comprises a control module, a data transmission module, a memory storage module and a power supply module.
As described above, the user can also operate the touch screen control unit 7 to control the power supply module 4 to supply power to the specific suspension support device 8, supply current, and set the lifting height, and the electromagnet 808 and the suspension magnet 807 generate magnetic induction force and drive the inner cylinder 802a to move upward, and during this lifting process, the inner cylinder 802a and the electromagnet 808, etc. are in a suspension state. The reduced value of the support force experienced by the first support spring 804 and the second support spring 805 during lifting is overcome by the magnetically induced force.
In addition, the distance sensor 810 senses the lifting height value in real time in the lifting process and feeds the lifting height value back to the touch screen control unit 7, and when the lifting height value set by a user is reached, the size of the current is gradually reduced, so that the magnetic induction force is reduced, and finally, the upward movement is stopped and the lifting height requirement set by the user is just met; subsequently, if the distance sensor 810 senses that the height is changed, the magnitude of the applied current can be automatically adjusted, so that the lifting height set by the user is always maintained.
Meanwhile, in order to achieve the purpose of saving electricity, a user can select to disconnect the power supply of the magnetic bolt mechanism 811, then the bolt 811d pushes the annular clamping groove 802d in time to clamp or support the inner cylinder 802a, and at the moment, the power supply of the electromagnet 808 can be disconnected, so that the purposes of accurately improving the supporting height and saving energy and reducing consumption are finally achieved.
In addition, the magnetic suspension-based nursing bed for the aged further comprises a wearable intelligent bracelet 10, wherein the intelligent bracelet 10 comprises a bracelet body 101, a heart rate sensor 102, a sound sensor 103, a display screen 104 and a Bluetooth module 105.
