[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] like Figure 1-9As shown, a nursing bed structure includes a bed frame 1, on which several movable support plates are arranged in a row. Adjacent movable support plates are hinged together, and all movable support plates together form a bed panel 2. An up-and-down turning structure 3 and a left-and-right turning structure 4 are installed under the bed panel inside the bed frame. In use, the up-and-down turning structure enables the bed to lift the rehabilitation personnel upward, while the left-and-right turning structure enables the bed to assist the rehabilitation personnel in turning to the side, thus enabling the rehabilitation personnel to move with the help of the bed.

[0022] In this embodiment, to enable rolling over and turning left and right, the lengths of the movable support plates from head to foot of the bed are different. Each movable support plate consists of an upper body board 5, a seat board 6, a leg board 7, and a tail board 8, arranged sequentially from head to foot. Each of these boards is composed of three transverse support plates 9: the upper body board consists of three upper body support plates 9-1 (from left to right), the seat board consists of three seat support plates 9-2 (from left to right), the leg board consists of three leg support plates 9-3 (from left to right), and the tail board consists of three tail board support plates 9-4 (from left to right). The support plates of the upper body board and the seat board are positioned as follows: The support plates of the leg bed board and the support plates of the tail bed board are all hinged. The hinges can be made by installing corresponding hinge pieces on adjacent support plates, and the corresponding hinge pieces are hinged together by a pivot. The support plates of the upper body bed board and the corresponding support plates of the seat bed board, the support plates of the seat bed board and the corresponding support plates of the leg bed board, and the support plates of the leg bed board and the corresponding support plates of the tail bed board are all hinged. The upper body bed board is the longest and is used to support the upper body of the rehabilitation personnel. When in use, the upper body bed board is flipped up to assist the rehabilitation personnel in turning upward. When it is necessary to turn to the left or right, the leftmost or rightmost support plate of the upper body bed board, seat bed board, leg bed board, and tail bed board is flipped to assist the rehabilitation personnel in turning to the side.

[0023] In this embodiment, to specifically achieve the upward tilting of the upper bed board around the hinge joint between the upper bed board and the seat bed board, the tilting structure includes an upward tilting mechanism 10, which includes an upward tilting frame 11. The upward tilting frame is movably connected to the bed frame and abuts against the underside of the upper bed board. A movable seat 12 structure connected to the upward tilting frame is installed in the middle of the bed frame. The bed frame is also provided with an upper drive mechanism 13 for driving the upward tilting frame to tilt. In use, the upward tilting is driven by the upper drive mechanism. The rotating frame is raised to achieve the flipping of the upper bed board. More specifically, the upper flipping frame is a rectangular frame, and the movable seat structure includes symmetrically arranged fixed seats 14. A horizontal slide groove 15 is installed on the fixed seat. Both the horizontal slide groove and the fixed seat are arranged along the length of the bed. The fixed seat is installed on the bed frame support and below the upper bed board on the side near the seat board. The two ends of the fixed seat are located below the upper bed board and below the seat board, respectively. A rocker arm 16 is symmetrically fixed to one side of the upper flipping frame. That is, the entire upper flipping frame... The body is located under the upper bed board. The side of the upper flip-up frame closest to the seat bed board is located below the edge of the upper bed board and slides under the upper bed board. The side of the upper flip-up frame away from the seat bed board is hinged under the upper bed board. The large projection of the rocker arm on the horizontal plane is perpendicular to the outer wall of the side of the upper flip-up frame closest to the seat bed board. A roller 17 is rotatably connected to one end of the rocker arm, and the roller slides in a horizontal groove. A swing arm 18 is hinged to the other end of the rocker arm, and the other end of the swing arm is rotatably connected to a fixed base. Specifically, the other end of the swing arm rotates... The rocker arm is connected to the fixed seat at one end located under the upper bed board. The outer wall of the rocker arm hinged to the rocker arm is fixed to the lower part of the upper flip frame. In use, when the upper drive mechanism drives the middle part of the upper flip frame to flip upward, the drive mechanism drives the side of the upper flip frame away from the bed board to flip. At the same time, the rocker arm and rocker arm smoothly assist the side of the upper flip frame closest to the bed board to slide down the upper flip frame, so that the entire upper flip frame gradually changes from a horizontal state to an inclined state, thereby driving the upper bed board to flip upward, so as to assist the rehabilitation personnel to get up.

[0024] In this embodiment, to enable the upper drive mechanism to drive the upper tilting frame to tilt, the upper drive mechanism includes symmetrically arranged swing drive rods 19. The two swing drive rods are connected in the middle by a synchronous rod. A first swing seat 20 is provided on the bed frame next to the fixed seat, corresponding to the two swing drive rods. The two fixed seats can be located between the two first swing seats. One end of each swing drive rod is rotatably connected to the corresponding first swing seat, and the other end is hinged to the same side of the upper tilting frame. Specifically, the swing drive rod is a downwardly convex arc-shaped rod. The projection of the arc-shaped rod on the horizontal plane is parallel to the left and right sides of the upper tilting frame. The arc-shaped rod is located below both sides of the upper tilting frame. One end of the arc-shaped rod is hinged to the middle of the side of the upper tilting frame on the same side, and the other end is hinged to the corresponding first swing seat. The bed frame is hinged to the first swing seat. An upper drive electric actuator 21 is provided to drive one of its swing drive rods to swing. The upper drive electric actuator is located below the hinge of the bed seat. The non-telescopic end of the upper drive electric actuator is hinged to the bed frame. The end of one of its swing drive rods extends out of the first swing seat to form an extended end 22. The extended end can be Y-shaped. At the same time, the Y-shaped opening of the extended end extends downward. The extended end is hinged to the telescopic end of the upper drive electric actuator, that is, the telescopic end of the upper drive electric actuator is hinged between the Y-shaped opening of the extended end. When the telescopic end of the upper drive electric actuator can drive the extended end to rotate around the corresponding first swing seat, it will drive the swing drive rod on that side to rotate around the corresponding first swing seat. Through the synchronizing rod, it will drive the swing drive rod on the other side to rotate around the corresponding first swing seat. This will enable the other ends of the two swing drive rods to jointly drive the middle of the left and right sides of the upper tilting frame to lift upward, thereby driving the upper tilting frame to tilt.

[0025] In this embodiment, to enable flexion movements of the thighs and calves of the rehabilitation personnel, the over-and-under structure includes a down-turning mechanism 41. The down-turning mechanism includes a rotating rod 23, which is positioned along the width of the bed. The rotating rod is rotatably connected to the bed frame and located below the hinge point between the seat and leg panels. Symmetrical abutment rods 24 are installed on the outer wall of the rotating rod, with the ends of the abutment rods abutting against the lower part of the leg panel, located below the side of the leg panel closest to the seat. A bearing support rod 25 is hinged to the outer wall of the rotating rod between the two abutment rods. An existing gas spring rod 42, which supports the bearing support rod, is hinged to the bed frame. The bearing support rod abuts against the leg panel and the tail panel. In the combined structure, a rotating rocker seat 26 is provided on the outer periphery of the rotating rod, and a lower drive electric push rod 27 is hinged to the bed frame. The telescopic end of the lower drive electric push rod is rotatably connected to the rotating rocker seat. By extending or retracting the telescopic end of the lower drive electric push rod, the outer end of the rotating rocker seat is rotated, which in turn drives the rotating rod to rotate, ultimately realizing the rotation of the abutment rod. This, in turn, causes the end of the abutment rod to lift the leg bed board close to the seat bed board, causing the leg bed board and the seat bed board to form an upward protrusion, which facilitates the bending movement between the thigh and lower leg of the rehabilitation personnel. At the same time, because the gas spring rod presses against the support rod, the tail bed board can be adaptively flipped. In this embodiment, turning over refers to the bending movement between the thigh and lower leg.

[0026] In this embodiment, the supporting rod is a bent rod with an obtuse angle, with the horizontal part on top and the inclined part on the bottom. A support rod seat is provided on the rotating rod body corresponding to the supporting rod. The end of the inclined part of the supporting rod is rotatably connected to the support rod seat. The inclined part of the supporting rod and the support rod seat are hinged via a rotating shaft. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixed to the support rod seat, and the other end is fixed to the end of the inclined part of the supporting rod. The gas spring rod is located below the horizontal part of the supporting rod. The lower end of the gas spring rod is hinged to the bed frame, and the upper end is hinged to the horizontal part of the corresponding supporting rod. The horizontal part of the supporting rod abuts against the side support plate on the same side of the leg bed board and the tail bed board. Under normal conditions, the horizontal part of the supporting rod is used to abut against the leg bed board and the tail bed board. When the end of the abutting rod pushes up the leg bed board, the tail bed board is supported by the torsion spring, the supporting rod, and the gas spring rod.

[0027] In this embodiment, to achieve left and right turning, the left and right turning structure includes symmetrically arranged side turning mechanisms 40. Each side turning mechanism includes a support plate 28, which is arranged along the length of the bed frame. The support plate is located under the support plate on the side of the upper bed board and the seat bed board. That is, the support plates of the two side turning mechanisms are respectively located under the outer edge of the support plate on the same side of the upper bed board and the seat bed board. By raising and lowering the support plate, the support plates on both sides of the upper bed board and the seat bed board are driven to turn around the hinge point between the side support plates and the middle support plate, so as to achieve turning to either the left or right side. The headboard side of the bed frame is symmetrically rotatably connected to auxiliary connecting rods 29. That is, the bed frame is symmetrically rotatably connected to the auxiliary connecting rods on the inside of the headboard side. One end of the auxiliary connecting rod is rotatably connected to the bed frame, and the other end is rotatably connected to one end of the support plate. The other end of the support plate is hinged to a side drive mechanism 30. The side drive mechanism drives the support plate to rise, and the auxiliary connecting rod plays an auxiliary role in raising the plate.

[0028] In this embodiment, in order to realize the side drive mechanism to drive the bearing plate to lift, the specific structure of the side drive mechanism is as follows: the side drive mechanism includes a side electric push rod 31, the side electric push rod is oriented in the direction of the bed width, that is, the side electric push rod is projected in the direction of the bed width on the horizontal plane, the non-telescopic end of the side electric push rod is hinged to the bed frame and located under the seat board, the bed frame is symmetrically hinged with vertically arranged L-shaped brackets 32, the rotation surface of the L-shaped bracket is located in the direction of the bed width, the corner end of the L-shaped bracket is rotatably connected to the bed frame, and the two ends of the L-shaped bracket are respectively rotatably connected to the telescopic end of the side electric push rod and the hinged end of the non-auxiliary connecting rod of the bearing plate, that is, when the side electric push rod is extended or retracted, it drives one end of the L-shaped bracket to rotate around the corner end, thereby driving the other end to lift or lower the bearing plate.

[0029] In this embodiment, to prevent the tailboard from folding downwards when not assisting in the bending motion of the thighs and calves, tailboard limiting mechanisms 33 are installed under the left and right support plates of the leg bed board. The tailboard limiting mechanism includes a horizontally arranged U-shaped plate 34. The two ends of the U-shaped plate are bent upwards and fixed under the support plate of the leg bed board. The U-shaped area of ​​the U-shaped plate is located under the support plate of the tail bed board, that is, except for the area where the two ends of the U-shaped plate are bent upwards, the other area of ​​the U-shaped plate is located under the support plate of the tail bed board. A top wheel 35 is rotatably connected to the U-shaped area of ​​the U-shaped plate. The top wheel abuts against the support plate of the tail bed board, and the tail bed board is prevented from folding downwards by the top wheel pressing against the support plate of the tail bed board.

[0030] In this embodiment, for the sake of reasonable design, the bed frame includes a bottom support frame 36, with wheels 37 at the four corners of the bottom support frame, and a top support frame 38 above the bottom support frame. A steel frame structure 39 is provided inside the top support frame, inside the bottom support frame, and between the top and bottom support frames. The up-and-down turning structure and the left-and-right turning structure are installed on the steel frame structure, and the entire bed panel abuts against the top support frame.

[0031] In this embodiment, upper bed board hinge seats 43 are symmetrically arranged on the side of the upper flip frame away from the seat bed board. The upper bed board support plate located in the middle of the upper bed board is hinged between the two upper bed board hinge seats. The tail bed board support rod is connected between the horizontal ends of the two bearing support rods. The tail bed board support rod is symmetrically arranged on the tail bed board support rod. The tail bed board support plate located in the middle of the tail bed board is hinged between the two tail bed board hinge seats. The two upper bed board hinge seats and the two tail bed board hinge seats together limit the position of the overall bed board.

[0032] In this embodiment, a safety bar 45 is horizontally placed below the two support rods on the bed frame. The safety bar is used to prevent damage to the gas spring rod and torsion spring, which could cause the support rods to fall and consequently cause the seat and tailboard to tilt excessively downwards.
