[0028] Please refer to Figure 1-3 , Figure 1-3 Schematic diagram of the structure of a rehabilitation bed in a reset state from various viewing angles. The present application provides a rehabilitation bed, which includes a bed frame 10, a base assembly 20, a first turning board assembly 30, a second turning board assembly 40 and a turning mechanism 50.

[0030] The fixed plate base 22 is always fixed on the bed frame 10, and the back plate base 21 and the leg plate base 23 are arranged on the same side of the bed frame 10 as the fixed plate base 22. When the rehabilitation bed is in the reset state, the first turning state, the second turning state and the leg raising state, the back plate base 21 and the leg plate base 23 abut against the bed frame 10, and when in the back raising state and the back raising and leg raising state, the back plate base 21 and the leg plate base 23 are separated from the bed frame 10.

[0031] The first turning board assembly 30 includes a first backboard 31, a first fixing board 32 and a first leg board 33, and the second turning board assembly 40 includes a second backboard 41, a second fixing board 42 and a second leg board 43. The first backboard 31, the first fixing board 32 and the first leg board 33 are sequentially connected in a lateral direction, and the second backboard 41, the second fixing board 42 and the second leg board 43 are sequentially connected in a lateral direction. The first backboard 31 and the second backboard 41 are arranged on a side of the backboard base 21 away from the bed frame 10, the first fixing board 32 and the second fixing board 42 are arranged on a side of the fixing board base 22 away from the bed frame 10, and the first leg board 33 and the second leg board 43 are arranged on a side of the leg board base 23 away from the bed frame 10.

[0032] The first back plate 31 and the second back plate 41 both have a first end and a second end along the vertical direction, the first end of the first back plate 31 is arranged close to the first end of the second back plate 41, and the first end of the first back plate 31 and the first end of the second back plate 41 are both rotatably connected to the back plate base 21 with the transverse axis as the axis. The first fixed plate 32 and the second fixed plate 42 both have a first end and a second end along the vertical direction, the first end of the first fixed plate 32 is arranged close to the first end of the second fixed plate 42, and the first end of the first fixed plate 32 and the first end of the second fixed plate 42 are both rotatably connected to the fixed plate base 22 with the transverse axis as the axis. The first leg plate 33 and the second leg plate 43 both have a first end and a second end along the vertical direction, the first end of the first leg plate 33 is arranged close to the first end of the second leg plate 43, and the first end of the first leg plate 33 and the first end of the second leg plate 43 are both rotatably connected to the leg plate base 23 with the transverse axis as the axis.

[0033] like Figure 3 As shown, the turning mechanism 50 includes a first driving member 51, a first transmission assembly 52 and a turning member 53. The output end of the first driving member 51 is connected to the first transmission assembly 52, and the first transmission assembly 52 is connected to the turning member 53. The turning member 53 has a first end and a second end along the length direction of the turning member 53, the first end of the turning member 53 is arranged on a side of the first turning board assembly 30 close to the bed frame 10, and the second end of the turning member 53 is arranged on a side of the second turning board assembly 40 close to the bed frame 10.

[0034] In the first turning state, if Figure 4 , 5As shown, the first driving member 51 can drive the first transmission assembly 52 to move, so that the first transmission assembly 52 drives the first end of the turning member 53 to swing toward the end close to the first turning board assembly 30, so that the first end of the turning member 53 abuts against the side of the first turning board assembly 30 close to the bed frame 10, so that the first turning board assembly 30 is rotatably lifted relative to the base assembly 20. In one embodiment, a first turning frame 311 is provided on the side of the first turning board assembly 30 close to the bed frame 10, and in the first turning state, the first end of the turning member 53 abuts against the first turning frame 311, so that the first turning board assembly 30 is rotatably lifted relative to the base assembly 20. In order to ensure stability, the first end of the turning member 53 may include a first roller 531, and in the first turning state, the first roller 531 of the turning member 53 abuts against the first turning frame 311.

[0035] In the second turning state, if Figure 6 , 7 As shown, the first driving member 51 can drive the first transmission assembly 52 to move, so that the first transmission assembly 52 drives the second end of the turning member 53 to swing toward the end close to the second turning board assembly 40, so that the second end of the turning member 53 abuts against the side of the second turning board assembly 40 close to the bed frame 10, so that the second turning board assembly 40 is rotatably lifted relative to the base assembly 20. In one embodiment, a second turning frame 411 is provided on the side of the second turning board assembly 40 close to the bed frame 10, and in the second turning state, the second end of the turning member 53 abuts against the second turning frame 411, so that the second turning board assembly 40 is rotatably lifted relative to the base assembly 20. In order to ensure stability, the second end of the turning member 53 may include a second roller 532, and in the second turning state, the second roller 532 of the turning member 53 abuts against the second turning frame 411.

[0036] Since the first turning board assembly 30 of the rehabilitation bed can be turned up relative to the second turning board assembly 40, or the second turning board assembly 40 can be turned up relative to the first turning board assembly 30, it can help the patient to turn over to the left or to the right, and when turning over, only half of the bed board is lifted up, and the other half of the bed board is still in a flat state, and there is no need to tilt the entire bed surface. Compared with the prior art in which the entire bed surface is tilted, the angle of lifting half of the bed board can be set to be larger, and the bed board can be tilted at a larger angle, which saves time and effort for medical staff during operation and can reduce the nursing intensity of medical staff.

[0037] In one embodiment, if Figure 4-7As shown, the first driving member 51 includes a first motor, and the first transmission assembly 52 includes a first connecting rod 521 and a first rotating rod 522. The first connecting rod 521 has a first end and a second end along the length direction of the first connecting rod 521. The output shaft of the first motor is connected to the first end of the first connecting rod 521. The second end of the first connecting rod 521 is sleeved and fixed on the first rotating rod 522. The turning member 53 is sleeved and fixed on the first rotating rod 522. The telescopic movement of the output shaft of the first motor can drive the first connecting rod 521 to swing, so as to drive the first rotating rod 522 to rotate around the axis of the first rotating rod 522, so as to drive the turning member 53 to swing.

[0038] like Figure 3 As shown, Figure 3 The turning mechanism 50 is in the reset state. In the reset state, the turning member 53 is arranged parallel to the first turning frame 311, and the turning frame is arranged parallel to the second turning frame 411. Figure 5 As shown, Figure 5 In the first turning state of the turning mechanism 50, the output shaft of the first motor moves toward the side close to the first turning board assembly 30, driving the first end of the first connecting rod 521 to swing toward the side close to the first turning board assembly 30, so that the second end of the first connecting rod 521 drives the first rotating rod 522 to rotate in a first direction with the axis of the first rotating rod 522 as the axis. The first direction can be clockwise or counterclockwise, so as to drive the turning member 53 to rotate in the first direction with the axis of the first rotating rod 522 as the axis, so that the first end of the turning member 53 swings toward the end close to the first turning board assembly 30. Figure 7 As shown, Figure 7 In the second turning state of the turning mechanism 50, the output shaft of the first motor moves toward the side close to the second turning plate assembly 40, driving the first end of the first connecting rod 521 to swing toward the side close to the second turning plate assembly 40, so that the second end of the first connecting rod 521 drives the second rotating rod 622 to rotate in the opposite direction of the first direction with the axis of the first rotating rod 522 as the axial direction, so as to drive the turning member 53 to rotate in the opposite direction of the first direction with the axis of the first rotating rod 522 as the axial direction, so that the second end of the turning member 53 swings toward one end close to the second turning plate assembly 40. The turning mechanism 50 has a simple structure, low cost and stable transmission.

[0039] In a specific embodiment, Figure 5 and Figure 7 As shown, the output shaft of the first motor is perpendicular to the axis of the first rotating rod 522, the axis of the first rotating rod 522 is parallel to the horizontal direction, the turning piece 53 has a first end and a second end along the length extension direction of the turning piece 53, the first rotating rod 522 is connected to the position between the first end and the second end of the turning piece 53, and the axis of the first rotating rod 522 is perpendicular to the length extension direction of the turning piece 53.

[0040] Furthermore, the turning mechanism 50 can be arranged on the side of the first back plate 31 and the second back plate 41 close to the bed frame 10, the first turning frame 311 is arranged on the surface of the first back plate 31 close to the bed frame 10, and the second turning frame 411 is arranged on the surface of the second back plate 41 close to the bed frame 10. Since the space below the first back plate 31 and the second back plate 41 is large, the turning mechanism 50 is arranged below the first back plate 31 and the second back plate 41, and more space can be reserved for arranging other mechanisms at other positions. Of course, in other embodiments, the turning mechanism 50 can also be arranged at other positions, and the number of the turning mechanisms 50 can also be set to multiple.

[0041] In one embodiment, if Figure 1 As shown, the first back panel 31 and the second back panel 41 are arranged vertically side by side on the back panel base 21, the first fixed panel 32 and the second fixed panel 42 are arranged vertically side by side on the fixed panel base 22, and the first leg panel 33 and the second leg panel 43 are arranged vertically side by side on the leg panel base 23.

[0042] In one embodiment, if Figure 1 As shown, the rotation axis of the first back plate 31 and the back plate base 21 is the first rotation axis, the rotation axis of the second back plate 41 and the back plate base 21 is the second rotation axis, and the first rotation axis coincides with the second rotation axis. The rotation axis of the first fixed plate 32 and the fixed plate base 22 is the third rotation axis, the rotation axis of the second fixed plate 42 and the fixed plate base 22 is the fourth rotation axis, and the third rotation axis coincides with the fourth rotation axis. The rotation axis of the first leg plate 33 and the leg plate base 23 is the fifth rotation axis, the rotation axis of the second leg plate 43 and the leg plate base 23 is the sixth rotation axis, and the fifth rotation axis coincides with the sixth rotation axis. Furthermore, the first rotation axis, the second rotation axis, the third rotation axis, the fourth rotation axis, the fifth rotation axis, and the sixth rotation axis are arranged along the same straight line and are all parallel to the transverse direction to make the overall structure more compact.

[0043] In one embodiment, if Figure 2 , Figure 8 As shown, the back plate base 21 and the fixed plate base 22 are rotatably connected with the vertical axis, the first back plate 31 and the first fixed plate 32 are rotatably connected with the vertical axis, and the second back plate 41 and the second fixed plate 42 are rotatably connected with the vertical axis.

[0044] The rehabilitation bed also includes a backboard lifting mechanism 60, which includes a second driving member 61, a second transmission assembly 62 and a backboard lifting member 63. The output end of the second driving member 61 is connected to the second transmission assembly 62, the first end of the backboard lifting member 63 is connected to the backboard base 21, and the second end of the backboard lifting member 63 is connected to the second transmission assembly 62. In the back-lifting state or the back-lifting and leg-lifting state, the second driving member 61 can drive the second transmission assembly 62 to move, so that the second transmission assembly 62 drives the backboard lifting member 63 to swing toward the side away from the bed frame 10, so that the backboard base 21, the first backboard 31, and the second backboard 41 are rotationally lifted relative to the bed frame 10, and the second driving member 61 can drive the second transmission assembly 62 to move, so that the second transmission assembly 62 drives the backboard lifting member 63 to swing toward the side close to the bed frame 10, so that the backboard base 21, the first backboard 31, and the second backboard 41 are rotationally dropped relative to the bed frame 10 until they return to the reset state.

[0045] Due to the requirement of turning over, the first back panel 31 and the second back panel 41 are rotatably connected to the back panel base 21, and the first back panel 31 and the second back panel 41 cannot be completely separated from the back panel base 21 to lift the patient's back. Therefore, the back panel lifting member 63 of the back panel lifting mechanism 60 is connected to the back panel base 21 to lift the entire back panel base 21, so that the back panel base 21 can drive the first back panel 31 and the second back panel 41 to lift, thereby preventing the back lifting state and the turning over state from interfering with each other, so that the bed can have the functions of back lifting and turning over at the same time.

[0046] In one embodiment, the second driving member 61 includes a second motor, the second transmission assembly 62 includes a second connecting rod 621 and a second rotating rod 622, the second connecting rod 621 has a first end and a second end along the length direction of the second connecting rod 621, the output shaft of the second motor is connected to the first end of the second connecting rod 621, the second end of the second connecting rod 621 is sleeved and fixed on the second rotating rod 622, and the second end of the back plate lifting member 63 is sleeved and fixed on the second rotating rod 622. The telescopic movement of the output shaft of the second motor can drive the second connecting rod 621 to swing, so as to drive the second rotating rod 622 to rotate around the axis of the second rotating rod 622, so as to drive the back plate lifting member 63 to swing.

[0047] like Figure 2 As shown, Figure 2 is the reset state of the back plate lifting mechanism 60, such as Figure 8 As shown, Figure 8It is the back-lifting state of the backboard lifting mechanism 60. When lifting the back, the output shaft of the second motor moves toward the side close to the backboard base 21, driving the first end of the second connecting rod 621 to swing toward the side close to the backboard base 21, so that the second end of the second connecting rod 621 drives the second rotating rod 622 to rotate in the second direction with the axis of the second rotating rod 622 as the axis, and the second direction can be clockwise or counterclockwise, so as to drive the backboard lifting member 63 to rotate in the second direction with the axis of the second rotating rod 622 as the axis, so that the first end of the backboard lifting member 63 swings toward the end away from the bed frame 10. During resetting, the output shaft of the second motor moves toward the side away from the backboard base 21, driving the first end of the second connecting rod 621 to swing toward the side away from the backboard base 21, so that the second end of the second connecting rod 621 drives the second rotating rod 622 to rotate in the opposite direction of the second direction with the axis of the second rotating rod 622 as the axial direction, so as to drive the backboard lifting member 63 to rotate in the opposite direction of the second direction with the axis of the second rotating rod 622 as the axial direction, so that the first end of the backboard lifting member 63 swings toward the end close to the bed frame 10 until it reaches the resetting state.

[0048] In one embodiment, if Figure 8 As shown, in order to ensure stability, the backboard lifting member 63 may include a first lifting rod 631, a second lifting rod 632 and a third lifting rod 633.

The first lifting rod 631, the third lifting rod 633, the second lifting rod 632 and the backboard lifting member 63 are roughly parallelogram-shaped, which can improve the stability when lifting the back.

[0049] In one embodiment, if Figure 2 , Fig. 9 As shown, the leg plate base 23 is rotatably connected to the fixed plate base 22 with the vertical axis as the axis, the first fixed plate 32 and the first leg plate 33 are rotatably connected with the vertical axis as the axis, and the second fixed plate 42 and the second leg plate 43 are rotatably connected with the vertical axis as the axis.

[0050] The rehabilitation bed also includes a leg lifting mechanism 70, which includes a third driving member 71, a third transmission assembly 72 and a leg lifting member 73. The output end of the third driving member 71 is connected to the third transmission assembly 72, the first end of the leg lifting member 73 is connected to the leg base 23, and the second end of the leg lifting member 73 is connected to the third transmission assembly 72. In the leg lifting state or the back lifting and leg lifting state, the third driving member 71 can drive the third transmission assembly 72 to move, so that the third transmission assembly 72 drives the leg lifting member 73 to swing toward the side away from the bed frame 10, so that the leg base 23, the first leg board 33, and the second leg board 43 are rotationally lifted relative to the bed frame 10, and the third driving member 71 can drive the third transmission assembly 72 to move, so that the third transmission assembly 72 drives the leg lifting member 73 to swing toward the side close to the bed frame 10, so that the leg base 23, the first leg board 33, and the second leg board 43 are rotationally dropped relative to the bed frame 10 until they return to the reset state.

Therefore, the leg board lifting member 73 of the leg board lifting mechanism 70 is connected to the leg board base 23 to lift the entire leg board base 23, so that the leg board base 23 can drive the first leg board 33 and the second leg board 43 to lift, thereby preventing mutual interference between the leg lifting state and the turning over state, so that the bed can have the functions of leg lifting and turning over at the same time.

The telescopic movement of the output shaft of the third motor can drive the third connecting rod 721 to swing, so as to drive the third rotating rod 722 to rotate around the axis of the third rotating rod 722, so as to drive the leg lifting member 73 to swing.

[0053] like Figure 2 As shown, Figure 2 The leg lifting mechanism 70 is in the reset state, such as Fig. 9 As shown, Figure 8It is the leg lifting state of the leg board lifting mechanism 70. When lifting the leg, the output shaft of the third motor moves toward the side close to the leg board base 23, driving the first end of the third connecting rod 721 to swing toward the side close to the leg board base 23, so that the second end of the third connecting rod 721 drives the third rotating rod 722 to rotate in the third direction with the axis of the third rotating rod 722 as the axial direction, and the third direction can be clockwise or counterclockwise, so as to drive the leg board lifting member 73 to rotate in the third direction with the axis of the third rotating rod 722 as the axial direction, so that the first end of the leg board lifting member 73 swings toward the end away from the bed frame 10. During resetting, the output shaft of the third motor moves toward the side away from the leg board base 23, driving the first end of the third connecting rod 721 to swing toward the side away from the leg board base 23, so that the second end of the third connecting rod 721 drives the third rotating rod 722 to rotate in the opposite direction of the third direction with the axis of the third rotating rod 722 as the axial direction, so as to drive the leg board lifting member 73 to rotate in the opposite direction of the third direction with the axis of the third rotating rod 722 as the axial direction, so that the first end of the leg board lifting member 73 swings toward the end close to the bed frame 10 until it reaches the reset state.

[0054] Preferably, if Figure 2 As shown, the second motor is roughly fixed on the bed frame 10 below the backboard base 21, and the second motor can also be roughly fixed on the bed frame 10 below the leg board base 23. The second motor and the third motor are roughly fixed on the bed frame 10 below the fixed plate base 22, and the first motor and the second motor are staggered in the vertical direction. This arrangement can reasonably arrange the space under the bed board and prevent the movements of various mechanisms from interfering with each other.
