[0036] The rotating driving unit 3 is arranged between the bed frame 1 and the mattress frame 2 to drive the mattress frame 2 to rotate relative to the bed frame 1.

[0037] In the hinged structure of each support plate of the mattress frame 2, the adjacent support plates are hinged by connecting ears and a hinge pin. Specifically, the side surfaces of the hip support plate 23 and the back support plate 21 are provided with L-shaped connecting ears, connecting holes are formed in the connecting ears, the connecting holes of the two connecting ears are butted and then the hinge pin is inserted, so that the hip support plate 23 and the back support plate 21 are hinged, and the side of the back support plate 21 away from the hip support plate 23 can be flipped up and down.

[0038] In the structure of the mounting frame 27, two main beams extending in the same direction as the mattress frame 2 and a positioning rod arranged between the two main beams for positioning the two main beams are included. The length of the main beam in the mounting frame 27 is greater than the length of the hip support plate 23, so the two ends of the main beam extend to the outside of the hip support plate 23, respectively, for supporting the back support plate 21 and the thigh support plate 24 in the horizontal state, so as to ensure the stability of the entire mattress frame 2 in the lying position.

[0039] In the mounting frame 27, the main beam only extends to the lower side of the thigh support plate 24 and does not interfere with the flipping of the calf support plate 25. Therefore, when the mattress frame 2 is switched to the off-bed position, the side of the calf support plate 25 away from the thigh support plate 24 can be flipped to the inside of the bed frame 1 as shown in Figure 6 , which facilitates the patient to get off the bed.

[0040] In order to further improve the stability of the mattress frame 2 in the lying position, the bed head and the bed tail of the bed frame 1 are respectively provided with a first cross beam 12 for supporting the back support plate 21 and a second cross beam 11 for supporting the calf support plate 25.
