The parts of the top of the bed body frame 4 except the side turning mechanism 6 are covered with fixed bed boards 7.

The side-turning mechanism 6 comprises two side-turning units which are arranged on the bed body frame 4 in a centering way. The two side turning units are arranged at intervals, and the distance between the two side turning units is smaller than the width of the wheelchair abdicating notch 4-1, so that the side turning units can drive the side turning plates 13 on the wheelchair module 2 to turn over together. The side-turning unit comprises a side-turning bracket 6-1, a side-turning bed plate 6-2 and a side-turning power element. The inner side edge of the side-turning bracket 6-1 is hinged with the bed body frame 4. The side-turning bed plate 6-2 is fixed on the upper side of the side-turning bracket 6-1; in a flat state, the edge of the inner side of the side-turning bed plate 6-2 is aligned with the side of the wheelchair abdicating notch 4-1. The side-turning power element adopts a side-turning electric push rod 6-3. One end of the side-turning electric push rod 6-3 is hinged with one side of the bottom of the bed body frame 4, and the other end is hinged with the outer edge of the bottom surface of the side-turning support 6-1. The side-turning bracket 6-1 can be driven to turn inwards by the stretching of the side-turning electric push rod 6-3, so that a user is driven to turn to the middle position of the bed, and the user is ensured to move to the wheelchair module 2 completely.

The two sides of the chair frame 8 are provided with guide sliding blocks 19. The rear end of the guide slider 19 is provided with a chamfer. Under the state that the wheelchair module 2 and the bedstead module 1 are combined together, the two guide sliders 19 and the two guide rails 18 on the wheelchair abdicating notch 4-1 respectively form a sliding pair, so that the stable and reliable splicing of the wheelchair module 2 and the bedstead module 1 is ensured. Two power wheels 9 are arranged at the rear side of the bottom of the chair frame 8 and are respectively driven by two motors. Two universal wheels 10 are mounted on the front side of the bottom of the chair frame 8. The width of the chair frame 8 corresponds to the width of the wheelchair abdicating gap 4-1 on the bed body frame 4, so that the wheelchair module 2 can be clamped into the wheelchair abdicating gap 4-1.

The cushion plate 11 is fixed to the top surface of the seat frame 8. The backrest assembly includes a backrest plate 12, a side tilt plate 13 and a backrest tilt power member.

The inner side edges of the two side turning plates 13 are respectively hinged with the inner side edges of the two side abdicating notches on the backrest plate 12. The limit position of the side turning plate 13 is limited by a limit block; when the side flaps 13 are aligned with the back rest 12, a limit position is reached, in which the side flaps 13 can only be tilted to the front side of the back rest 12.

As an alternative solution, the side flipper 13 is attracted by magnets fixed to the back rest 12 when aligned with the back rest 12, thereby ensuring that the position of the side flipper 13 remains stable during use of the wheelchair module 2.

As an optional technical solution, a torsion spring or a spring is arranged between the side turning plate 13 and the backrest plate 12. The spring or the elasticity of the spring to the side flap 13 tends to drive the side flap 13 to flip over towards the back of the back plate 12, thereby ensuring that the position of the side flap 13 remains stable during use of the wheelchair module 2.

The foot rest assembly comprises a leg plate 15 and a foot rest tilt power element. The inner edge of the foot plate is hinged with the front side of the top of the chair frame 8. The foot rest overturning power element is a foot rest electric push rod 16; one end of a foot rest electric push rod 16 is hinged with the front side of the chair frame 8, and the other end is hinged with the bottom of the foot plate to turn over the leg plate 15.

As an optional technical solution, the foot rest assembly further comprises a foot rest 17; the inside edge of the footrest 17 is connected to the outside edge of the leg plate 15.

Further, a footrest 17 is hinged to the leg plate 15, the footrest 17 being turned over under the drive of the motor to provide support when a user sits on the wheelchair module 2.

The present embodiment also provides another implementation scheme: the hinge shaft of the leg plate 15 and the chair frame 8 serves as a first hinge shaft; the hinge axis of the footrest 17 and the leg plate 15 serves as a second hinge axis. The first articulated shaft is fixed with the chair frame 8; the second articulated shaft is fixed with the footrest 17; the first articulated shaft and the second articulated shaft are linked in a gear and belt wheel mode, and constant-speed reverse rotation is achieved. The first articulated shaft and the second articulated shaft rotate reversely at a constant speed by taking the leg plate 15 as a reference system; thereby, the footrest 17 is kept parallel to the cushion plate 11, i.e. the footrest 17 is kept horizontal during the turning over of the leg plate 15.

As shown in fig. 3 and 4, the armrest assembly 3 includes two armrest bodies. The two armrest bodies are respectively arranged at two sides of the cushion plate 11 in a lifting way. When the armrest body is at the lower limit position, the top surface is flush with the cushion plate 11 and is used as a part of the mattress; when the armrest main body is at the upper limit position, the user can put the arm and can bear pressure; the lifting of the armrest main body is realized in a manual mode or an automatic mode; the automatic mode adopts a mode of matching a motor with a gear rack or a mode of driving an electric push rod.

The cushion plate 11, the top surface of the handrail main body, the backrest plate 12, the side-turning plate 13, the leg plate 15, the fixed bed plate 7 and the side-turning bed plate 6-2 are all covered with elastic layers, so that a user can lie on the upper surface more comfortably. The elastic layer is made of sponge wrapped by leather sleeves.

In an initial state, the wheelchair module 2 is positioned in the wheelchair abdicating notch 4-1 of the bed body frame 4, the wheelchair module 2 is in a flat state, and the cushion plate 11, the backrest plate 12 and the push plate are parallel and level with each other and are parallel and level with the fixed bed plate 7 on the bed body module 1. The seat cushion plate 11, the top surface of the handrail main body, the backrest plate 12, the side turning plate 13, the leg plate 15, the fixed bed plate 7 and the side turning bed plate 6-2 form a complete bed plate together.

Two side turning plates 13 on the backrest plate 12 are respectively placed on the two side turning supports 6-1 of the bedstead module 1. When the side turning bracket 6-1 is turned over, the corresponding side turning plate 13 is driven to rotate together.

firstly, two side-turning power elements in the side-turning mechanism 6 respectively drive two side-turning brackets 6-1 to turn upwards; the side-turning bracket 6-1 drives the side-turning bed board 6-2 on the corresponding bedstead module 1 and the side-turning board 13 in the wheelchair module 2 to turn upwards. Thereby pushing the user from different positions of the bed board to the middle position, the hip of the user is positioned on the cushion board 11, the back and the head are positioned on the backrest board 12, and the leg is positioned on the leg board 15.

Secondly, two side-turning power elements in the side-turning mechanism 6 respectively drive the two side-turning brackets 6-1 to reset downwards; the two armrest bodies of the wheelchair module 2 are raised to provide side protection and hand support for the user.

Thirdly, the backrest overturning power element drives the cushion plate 11 to overturn upwards; the leg plate 15 is driven by the foot rest turning power element to turn downwards, so that the user can be adjusted from the lying posture to the sitting posture.

And step four, the wheelchair module 2 leaves the bedstead module 1 under the driving of the power wheels 9.

The method for returning the wheelchair module 2 to the bed frame module 1 is opposite to the above process, and is not described herein.
