The lifting column 1301 penetrates through the top of the back plate 5 to form a sliding pair, the upper end of the lifting column 1301 is fixed on the suspension bracket 1302 through a screw, and the suspension bracket 1302 is a U-shaped bracket with adjustable extension length. One end of the linear driving device 1303 is fixed in the middle of the saddle-shaped back plate 5 through a bolt, and the other end of the linear driving device 1303 is fixed on the suspension bracket 1302. The linear actuator 1303 has a moving pair direction parallel to the bed direction, and the linear actuator 1303 in the lifting suspension frame 13 may be an electric push rod, a hydraulic cylinder, or a screw device.
Preferably, the lifting column 1301 of the lifting suspension 13 is guided by a guide block fixed inside the back plate, and a slide rail and a slider may be used.
Furthermore, the bottom of the base 1 is provided with casters, two sides of the base 1 are provided with movable doorframe 14, the sliding blocks at the bottom of the doorframe 14 are connected to the sliding rails at two sides of the base to form a sliding pair, and the sliding pair is perpendicular to the bottom surface.
As shown in fig. 6, the rehabilitation bed can realize sitting posture rehabilitation, and the lifting column jacking device 4 lifts the inverted L-shaped lifting column 3. The back plate driving device 6 pushes the saddle-shaped back plate 5 to rotate to the vertical position around the first rotating pair, and the leg plate linear driving device 10 retracts to drive the leg plate driving rod 1003 to rotate the leg plate 9 to the retracted position around the seat plate 7. At the moment, the rehabilitation bed is in a chair shape to carry out sitting posture rehabilitation training.
As shown in fig. 7, the rehabilitation bed can realize standing posture rehabilitation. The lifting column jacking device 4 lifts the inverted L-shaped lifting column 3; the back plate driving device 6 pushes the saddle-shaped back plate 5 to rotate to a vertical position around the first rotating pair; the linear driving device 801 retracts to drive the first connecting rod 802 and the second connecting rod 803 to rotate, so that the seat plate 7 rotates to the retracted position around the first rotating pair, and the leg plate linear driving device 10 extends to drive the leg plate driving rod 1003 to rotate the leg plate 9 to the extended position around the seat plate 7. At the moment, the rehabilitation bed is in a state that the seat plate and the leg plate are retracted backwards so as to carry out standing posture rehabilitation training.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope defined by the claims of the present invention.
