The other end of the first backboard hinge 6 is provided with a ninth connection hole 62. The other end of the first backboard hinge 8 is provided with a tenth connection hole 82. The third hinge rotating shaft 10 sequentially passes through the ninth connection hole 62, the spherical hole of the spherical bearing 11, and the tenth connection hole 82.

[0051] In this way, after the first hinge rotating shaft 7 sequentially passes through the fourth connection hole, the sixth connection hole 61, and the fifth connection hole 322, the fixation of the first backboard hinge 6 and the hip plate connecting member 3 can be realized. After the second hinge rotating shaft 9 passes through the seventh connection hole 52 and the eighth connection hole 81, the fixation of the first backboard hinge 8 and the backboard adapter block 5 can be realized. After the third hinge rotating shaft 10 sequentially passes through the ninth connection hole 62, the spherical hole of the spherical bearing 11, and the tenth connection hole 82, the fixation of the first backboard hinge 6, the first backboard hinge 8, and the oil cylinder unit can be realized. Thus, the movement of the first oil cylinder can drive the movement of the first backboard hinge 6 and the first backboard hinge 8, so as to drive the rotation of the first backboard assembly relative to the seat plate rotating shaft 4 through the movement of the first backboard hinge 6 and the first backboard hinge 8, and further realize the rotation and morphological transformation of the first backboard 1 relative to the second backboard 2.

One end of each sub-hinge is provided with an eighth connection hole 81, and the two eighth connection holes 81 are located on both sides of the seventh connection hole 52. The other end of each sub-hinge is provided with a tenth connection hole 82, and the two tenth connection holes 82 are located on one side of the two ninth connection holes 62 away from the spherical bearing 11.

[0054] Of course, the present utility model does not specifically limit the number of sub-hinges of the first backrest hinge 6 and the first backrest hinge 8. Those skilled in the art can choose that the number of sub-hinges of the first backrest hinge 6 and the first backrest hinge 8 is greater than 2 to ensure the reliability of the hinge connection, thereby ensuring the safety performance and service life of the medical bed.

[0055] Optionally, the first backrest assembly further includes a backrest adapter. The oil cylinder unit further includes a backrest oil cylinder 12 and a backrest oil cylinder shaft 13.

The backrest oil cylinder 12 is fixed to one end of the first backrest 1 away from the second backrest 2 through the backrest adapter.

[0056] Thus, the backrest oil cylinder 12 is fixed through the backrest adapter and the spherical bearing 11 and can slide relative to the backrest oil cylinder shaft 13. Therefore, the oil cylinder unit can drive the activities of the first backrest hinge 6 and the first backrest hinge 8, thereby driving the rotation of the backrest assembly relative to the seat plate rotating shaft 4 through the activities of the first backrest hinge 6 and the first backrest hinge 8, and further realizing the rotation and morphological transformation of the first backrest 1 relative to the second backrest 2.

Optionally, the second backrest assembly is configured to have the same structure as the first backrest assembly, and the proximal end of the second backrest assembly close to the first backrest 1 is configured to have the same structure as the distal end of the first backrest assembly away from the second backrest 2.

[0060] That is to say, the installation directions of the oil cylinders and the oil cylinder shafts of the first backrest assembly and the second backrest assembly are the same, and the second backrest 2 and the leg plate are also connected through the hinge structure of the present utility model described above.

[0061] Optionally, there are two groups of the hinge structures provided by the present utility model. The two groups of hinge structures are located on both sides in the width direction of the bed board and are symmetrically arranged to improve the safety performance and reliability of the medical bed.

[0062] The working principle of the present utility model is as follows:

[0063] After the first backboard assembly extends through the backboard oil cylinder 12, it rotates around the first hinge rotating shaft 7 through the first backboard hinge 6, and the first backboard hinge 8 rotates around the second backboard hinge rotating shaft. The backboard assembly rotates upward through the third hinge rotating shaft 10 by the first backboard hinge 8 and the first backboard hinge 6; conversely, after the first backboard assembly contracts through the backboard oil cylinder 12, it rotates around the first hinge rotating shaft 7 through the first backboard hinge 8, and the first backboard hinge 8 rotates around the second hinge rotating shaft 9. The first backboard assembly rotates downward through the third hinge rotating shaft 10 by the first backboard hinge 6 and the first backboard hinge 8. Thus, the activities of the first backboard hinge 6 and the first backboard hinge 8 drive the rotation of the first backboard assembly relative to the seat plate rotating shaft 4, and further realize the rotation and morphological transformation of the first backboard 1 relative to the second backboard 2.

[0064] The working principle of the second backboard assembly is the same as that of the first backboard assembly.
