Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1

[0034] Reference Figure 1-Figure 4 As shown, this embodiment 1 provides a multi-purpose bed for the elderly, including a bed frame 1, a weighing module 8 is arranged on the top of the bed support 11 of the bed frame 1, and is used to weigh and obtain the weight of the user; a support plate 7 is arranged on the top of the weighing module 8, wherein the length of the support plate 7 is less than the length between the front and rear plates of the bed frame 1, so as to avoid interference between the support plate 7 and the bed support 11 during the weighing process of the weighing module 8; a lifting mechanism 5 is evenly installed on the top of the support plate 7, wherein a hanging platform (not shown in the figure) for matching bolts is arranged at the bottom of the lifting mechanism 5, and the lifting mechanism 5 is fixed to the top of the support plate 7 by bolts, so as to facilitate the disassembly and replacement of the damaged lifting mechanism 5; a control switch 3 and a controller 4 are respectively arranged on the side walls of the bottom frame 12 of the bed frame 1, wherein the control switch 3 is used to control the power on and off and mode switching of the multi-purpose bed for the elderly; the controller 4 is electrically connected to the control switch 3, the lifting mechanism 5 and the weighing module 8 respectively;

[0035] The lifting mechanism 5 includes a bottom frame 51, a weighing module 52, a bottom plate 53, a metal column 54, a coil 55, an outer barrel 58, a top plate 56, a lifting column 57, a latex pad 510, a magnet 512 and a limit ring 513, wherein the bottom frame 51 is a hollow shell, and exhaust ports are evenly arranged at the lower end of the side wall of the bottom frame 51. When the lifting column 57 is lifted or lowered, the gas in the bottom frame 51 can be sucked in and discharged through the exhaust ports to avoid the internal air pressure of the bottom frame 51 affecting the lifting of the lifting column 57; an opening is arranged at the top of the bottom frame 51, the weighing module 52 is fixed to the bottom of the inner cavity of the bottom frame 51, the top of the weighing module 52 is fixed with a bottom plate 53, and a metal column 54 is fixed on the top of the bottom plate 53, and the metal column 54 is made of an iron column; the coil 55 is wound around the outside of the metal column 54, and the outer barrel 58 is sleeved on the outside of the coil 55, and a top plate 56 is fixed on the top of the metal column 54, and the top plate 56 The lifting column 57 is coaxially arranged with the top opening of the bottom frame 51, wherein the lifting column 57 is a hollow column with an opening at the bottom and a sealing at the top; the lower end of the lifting column 57 passes through the matching gap between the top plate 56 and the top of the bottom frame 51, and an air outlet 571 is provided at the upper end of the side wall of the lifting column 57. When the lifting column 57 is lifted, the gas in the middle of the lifting column 57 is discharged and sucked from the air outlet 571 to avoid the internal air pressure of the lifting column 57 affecting the lifting of the lifting column 57; the limiting ring 513 is fixedly connected to the bottom of the lifting column 57, and the difference between the inner and outer diameters of the limiting ring 513 is greater than the matching gap between the top plate 56 and the top opening of the bottom frame 51, which is used to prevent the lifting column 57 from escaping from the bottom frame 51; the magnet 512 is fixed to the top of the inner cavity of the lifting column 57, and a latex pad 510 is provided on the top of the lifting column 57 to improve the comfort of use; the weighing module 52 and the coil 55 are both electrically connected to the controller 4. When the coil 55 is energized, it generates magnetism and repels the magnet 512.

[0036] During normal use, the coil 55 is energized to suspend the lifting column 57. The repulsive force between the coil 55 and the magnet 512 is controlled by controlling the current of the coil 55. The hardness of the bed can also be adjusted by adjusting the repulsive force.

[0037] Furthermore, balls 59 are evenly arranged on the inner wall of the top opening of the bottom frame 51 and the outer wall of the top plate 56, and the balls 59 abut against the side walls of the lifting column 57; this arrangement can play a vertical guiding role for the lifting column 57, which is beneficial to the vertical lifting of the lifting column 57.

[0038] Furthermore, the inner and outer diameters of the limiting ring 513 respectively match the clearance between the outer barrel 58 and the inner cavity of the bottom frame 51; wherein the matching clearance between the inner and outer diameters of the limiting ring 513 and the inner cavity of the outer barrel 58 and the bottom frame 51 is 0.5-2mm, preferably 0.5-1mm.

[0039] Furthermore, a solenoid valve 511 is installed in the exhaust port at the lower end of the side wall of the bottom frame 51. The solenoid valve 511 is electrically connected to the controller 4. The solenoid valve 511 is in an open state during normal use and in a closed state when the power is off. When the power is off, the magnetic force of the coil 55 disappears, and the solenoid valve 511 closes automatically. A closed space is formed at the lower end of the bottom frame 51. Under the action of the air pressure in the bottom frame 51, the lifting column 57 slowly descends to avoid the lifting column 57 falling instantly when the power is off, which may cause harm to the user.

[0040] Furthermore, the top of the lifting mechanism 5 is covered with a cotton cushion 6 to improve the user's comfort.

[0041] As a further improvement, universal wheels are installed at the foot of the bed to facilitate the movement of the bed.

[0042] Furthermore, a backup battery 2 for powering the multi-purpose bed for the elderly is installed on the bed frame 1, so as to facilitate the mobile use of the multi-purpose bed for the elderly and the use in a power outage state.

[0043] This embodiment further provides a control method for the multi-purpose bed for the elderly as described above, comprising the following steps:

[0044] 1) The controller 4 controls the coils 55 in each lifting mechanism 5 to be energized, and after the coils 55 are energized, the lifting column 57 is lifted upward through the magnet 512;

[0045] 2) The weighing module 8 collects the user's weight data M in real time and sends the collected weight information M to the controller 4;

[0046] 3) The weighing module 52 in each lifting mechanism 5 collects the pressure information in real time and sends it to the controller 4, and the controller 4 counts the number T of the lifting mechanisms 5 that are under pressure;

[0047] 4) The controller 4 adjusts the current of the coil 55 in each pressurized lifting mechanism 5 in real time, so that the lifting column 57 can be adaptively raised and lowered, and the pressure detected by the weighing module 52 in each pressurized lifting mechanism 5 is the user's weight M divided by the number of pressurized lifting mechanisms 5 T, so that the downward parts of the user's body can be evenly stressed (similar to the human body floating on the water), so that the suspended cervical and lumbar vertebrae can be effectively supported, thereby improving the user's comfort.

[0048] When the user rolls over or performs any activity, the lifting mechanism 5 can be adjusted in real time so that the side of the user's body that is in contact with the bed can be evenly stressed.

[0050] This embodiment is basically the same as the first embodiment, and the only difference is that a solenoid valve 511 is installed in the air outlet 571, and the solenoid valve 511 is electrically connected to the controller 4. The solenoid valve 511 is in an open state during normal use and is in a closed state when the power is off; when the power is off, the magnetic force of the coil 55 disappears, the solenoid valve 511 will automatically close, and a closed space is formed at the upper end of the lifting column 57. Under the action of the air pressure in the lifting column 57, the lifting column 57 slowly descends, so as to avoid the lifting column 57 falling instantly when the power is off and causing harm to the user.

[0051] Embodiment 3

[0052] This embodiment is basically the same as the second embodiment, and the only difference is that the exhaust port and the air outlet 571 at the lower end of the side wall of the bottom frame 51 are both equipped with a solenoid valve 511, and the solenoid valve 511 is electrically connected to the controller 4. The solenoid valve 511 is in an open state during normal use and in a closed state when the power is off; when the power is off, the magnetic force of the coil 55 disappears, and the solenoid valve 511 is automatically closed, and a closed space is formed at the upper end of the lifting column 57 and the lower end of the bottom frame 51. Under the action of the air pressure in the bottom frame 51 and the lifting column 57, the lifting column 57 slowly descends to avoid the lifting column 57 falling instantly when the power is off to cause harm to the user.
