Referring to fig. 1-2, the present embodiment provides a multifunctional nursing bed 10. The nursing bed is used for leg nursing and rehabilitation. In the prior art, long-term bed rest is usually needed due to leg fracture or foot injury. The muscle atrophy of the leg is easy to cause by long-term bed rest, and the leg can be prevented from muscle atrophy by exercising before the fracture recovery or leg muscle can be exercised in advance to recover the leg on the premise of not influencing the fracture. The multifunctional nursing bed 10 comprises a bed board 100, bed legs 110, a backrest pad 120, a lower leg supporting pad 130 and a driving assembly 200. The bed plate 100 includes a first opening 101 and a second opening 102 arranged at an interval.

The bed legs 110 are disposed at the bottom of the bed board. The backrest pad 120 is rotatably disposed in the first opening 101. The back cushion can rotate around the edge of the first opening, and the purpose of rising and falling on the surface of the bed board is achieved. The backrest 120 is provided with a first protrusion 121 on a side thereof adjacent to the leg 110. The lower leg support pad 130 is movably disposed in the second opening 102. The lower leg support pad can be raised and lowered at the second opening. The driving assembly 200 is disposed below the top board 100. Wherein, the second opening is the rectangle opening, and the shape of shank supporting pad can match with second open-ended size, and the shank supporting pad can slide at the open-ended inner wall of second, therefore the second opening can restrict the shank supporting pad and move in vertical direction.

The driving assembly includes a base plate 210, a supporting bracket 220, a wheel 230, a driving device 240, a driving rod 310, a first link 320, a second link 330, a horizontal bar 340, and a control device 400. The supporting frame 220 is fixedly disposed on the bottom plate 210. The rotating wheel 230 is rotatably disposed on the supporting frame 220, and an eccentric shaft 232 is disposed at an edge of the rotating wheel 230. The driving device 240 is disposed on the supporting frame 220 and is used for driving the rotating wheel 230 to rotate. The eccentric shaft is driven to rotate when the rotating wheel rotates. One end of the driving rod 310 is rotatably disposed on the eccentric shaft, and the other end is rotatably connected to a rotating shaft 312. The driving rod 310 may be sleeved on the eccentric shaft through a bushing, and the bushing of the driving rod 310 may rotate relative to the eccentric shaft.

One end of the first link 320 is rotatably connected to the rotating shaft 312, and the other end is rotatably disposed on the bottom plate 210. One end of the first connecting rod can be rotatably sleeved on the rotating shaft 312 through the shaft sleeve. One end of the second connecting rod 330 is rotatably connected to the rotating shaft 312, and the other end is fixedly provided with a lower leg supporting pad 130. One end of the second link 330 may also be rotatably sleeved on the rotating shaft 312 through a shaft sleeve. I.e. the rotation axis 312 may have a certain length. The one end of first connecting rod, the one end of second connecting rod, the one end of actuating lever and the one end of horizon bar all can independently overlap respectively through a axle sleeve in proper order along the extending direction of axis of rotation and establish on axis of rotation 312, can independently rotate each other not influenced. The horizontal bar 340 is arranged parallel to the bed board 100. One end of the horizontal bar 340 is fixedly disposed on the rotation shaft 312, and the other end is provided with a second protrusion 342. An elastic support bar 41 is also included. One end of the elastic support rod 410 is fixed to the bottom plate 210, and the elastic support rod may be provided with a spring rod, which may be extended and retracted within a certain range under the action of a vertical force. The other end of the elastic support rod is provided with a fixed slideway 420, and the horizontal rod 340 is arranged in the fixed slideway 420 in a sliding way. The control device 400 is electrically connected to the driving device 240 for controlling the operating state of the driving device 240. The working state of the driving device comprises starting, stopping, accelerating rotation, decelerating rotation and the like.

When the control device 400 controls the driving device 240 to drive the rotating wheel 230 to rotate, the eccentric shaft 232 rotates around the center of the rotating wheel 230 and drives the end of the driving rod 310 to rotate, and the end of the driving rod 310 rotates to generate horizontal displacement. The horizontal component force at the other end of the driving rod drives the rotating shaft to generate a horizontal displacement, so that the rotating shaft 312 is close to or far away from the rotating wheel 230.

When axis of rotation 312 kept away from runner 230, the contained angle grow of first connecting rod 320 and second connecting rod 330 and horizontal plane, and first connecting rod and second connecting rod tend to vertically under the joint support of axis of rotation promptly, and first connecting rod can jack-up the axis of rotation at the in-process that tends to vertically, and the axis of rotation can drive the second connecting rod and have the displacement of vertical direction. At this time, the second link 330 is lifted to drive the shank support pad 130 to extend out of the surface of the bed plate 100. Since the rotation shaft moves horizontally away from the rotating wheel, the horizontal component force of the rotation shaft to the horizontal rod 340 causes the horizontal rod to move horizontally away from the rotating wheel 230 due to the horizontal rod being limited by the fixed slide way, and at this time, the second protrusion 342 pushes up the first protrusion 121, so that the back cushion 120 is lifted up from the surface of the bed plate 100. When a person lies on the bed body, the back cushion can enable the abdomen and the back of the person to be in a sitting state from a lying state. Meanwhile, if the shanks of the person are placed on the shank supporting pads, the shank supporting pads can drive the shanks of the person to rise horizontally, and at the moment, a doctor can observe the state of an illness, change medicines and the like conveniently. The discomfort caused by the tight position of the leg part due to the lifting of the rope is avoided. If the lower legs of the person are not placed on the lower leg supporting pads, the lower leg supporting pads can play the role of a small-sized table, and the patient can conveniently eat and read books and the like.

When the rotating shaft 312 is close to the rotating wheel 230, the included angle between the first connecting rod 320 and the second connecting rod 330 and the horizontal plane increases, that is, the included angle between the first connecting rod and the second connecting rod and the horizontal direction gradually decreases. The first connecting rod can drive the rotating shaft to move towards the gravity direction within a certain range when descending, the horizontal rod can tend to move towards the gravity direction under the driving of the rotating shaft, the horizontal rod can compress the elastic supporting rod to a certain degree under the action of the elastic supporting rod, and the elastic supporting rod can still support the horizontal rod to tend to be horizontal. At this time, the included angle between the second connecting rod 330 and the horizontal plane gradually decreases, and the lower leg supporting pad 130 is driven to return to the second opening 102 under the driving of the downward movement trend of the rotating shaft, the second protrusion 342 is far away from the first protrusion 121, and the backrest pad 120 returns to the first opening 101. At this time, the bed body is restored to the original horizontal state. The patient can lie flat for rest.

If the drive means drives the wheels to rotate continuously, the backrest cushion and the calf support cushion are raised and then retracted simultaneously. When a patient lies on the bed and the lower legs are supported on the lower leg supporting pads, the purpose of continuously moving the joints of the abdomen, the back and the legs can be achieved. The rotating speed of the rotating wheel can be adjusted by adjusting the working frequency of the driving device.

Referring to fig. 3-4, in one embodiment, the deck further includes a recess 103 and a thigh support pad 140. The recess 103 is disposed between the first opening 101 and the second opening 102. The thigh support pad 140 is rotatably disposed in the recess 103. A pressure sensor 142 is disposed within the thigh support pad 140. The pressure sensor 142 is electrically connected to the control device 400. When the patient's calf may not need to be supported for a short time and the thigh muscles need to be exercised, the thigh support pad 140 may be screwed out of the surface of the bed plate 100. Meanwhile, the thigh will be pressed on the thigh supporting pad, and when the pressure value sensed by the pressure sensor 142 is greater than a predetermined value, for example, 5N, the control device 400 controls the driving device 240 to rotate, so that the rotating shaft 312 is far away from the rotating wheel 230, and the second connecting rod 330 drives the shank supporting pad 130 to extend out of the surface of the bed plate 100 to rapidly support the shank about to fall down. Therefore, the condition that the leg of the patient falls down to injure the lower leg again because the thigh muscle cannot insist can be avoided.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-described examples merely represent several embodiments of the present application and are not to be construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
