step one, a user inputs an operation instruction for semi-lying at a user end, and a controller controls an electric rod on the bed body 8 to automatically adjust the angles of a back plate, a leg rest plate and/or a footrest, or the user manually adjusts the angles of the back plate, the leg rest plate and/or the footrest of the bed body 8;

secondly, a third sensor monitors the horizontal position of the backrest plate and transmits a detection signal to a controller, the controller controls a second clutch to be powered off, so that the rotary pipe 5 is separated from the lifting mechanism 1, and controls a first clutch to be powered on, so that the rotary pipe 5 and the movable mechanism 4 are fixedly attracted;

step three, the controller controls the drawing motor 71 to rotate reversely, the drawing motor 71 releases the tension of the trapezoidal lead screw 74 and the steel wire rope 75, the drawing guide post 77 is ejected out of the spring cavity by the pushing force of the spring 76 under the condition that the tension of the drawing motor 71 does not exist, and the drawing guide post 77 releases the locking of the one-way joint 6;

step four, the one-way joint 6 is subjected to angle steering along with the folding of the backrest plate, the leg rest plate and/or the footrest, and the movable mechanism 4 rises to drive the telescopic guide rail 41 to extend; the extension of the telescopic guide rail compensates the length shortage of the back plate, the leg rest plate and/or the foot rest plate caused by rising and inclining, and when the back plate, the leg rest plate and/or the foot rest plate fall down, the telescopic guide rail retracts, so that the patient can be better assisted to realize a half-lying state;

and step five, when the third sensor monitors that the backrest plate, the leg rest plate and/or the footrest are folded to a set angle, the controller controls the electric rod to stop running, or the user stops manually adjusting the angle of the backrest plate, the leg rest plate and/or the footrest of the bed body 8.

The horizontal position of back-up plate is judged to the third sensor, when back-up plate, leg back-up plate and/or footrest need rise angle of adjustment, back-up plate, leg back-up plate and/or footrest leave the third sensor this moment, and third sensor transmission signal gives the controller, can take place the operating instruction to first clutch, second clutch, pull motor, the electric pole on the bed body after the controller analysis, controls its operation step operation according to the action of partly lying.

The rotating mechanism and the one-way joint are connected together through the rotating pipe, namely the rotating angle of the rotating mechanism is the same as that of the one-way joint, when the first sensor identifies the rotating angle of the rotating motor and transmits the rotating angle to the controller, the controller can analyze the position angle of the one-way joint, the number of turns of the rotating motor in left and right rotation and the curling length of the bed sheet, so that the first clutch, the second clutch, the lifting mechanism, the drawing motor and the rotating motor are controlled to operate according to the operation steps of turning over.

The controller can be set by a program to control the auxiliary turning-over device to move according to the setting requirements, for example, the auxiliary turning-over device can regularly turn over in the daytime so as to prevent skin sores of long-term bedridden patients, and can be matched with detection equipment such as a heart rate cushion and the like at night to passively prevent snoring and the like by turning over.

The embodiment has the following beneficial effects:
