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 rebounds out of the spring cavity by the pushing force of the spring 76 under the condition that the tension of the drawing motor 71 is not applied, 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 ascends 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 footrest caused by rising and inclining, and when the back plate, the leg rest plate and/or the footrest 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 bedstead body 8.

The third sensor judges the horizontal position of the backrest plate, when the backrest plate, the leg rest plate and/or the footrest need to be lifted to adjust the angle, the backrest plate, the leg rest plate and/or the footrest leave the third sensor at the moment, the third sensor transmits a signal to the controller, and the controller analyzes the signal and then generates an operation instruction to the electric rod on the first clutch, the second clutch, the drawing motor and the bedstead body to control the operation of the operation step according to the half-lying action.

The rotating mechanism and the one-way joint are connected together through the rotating pipe, namely the rotating mechanism and the one-way joint have the same rotating angle, 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 actions.

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:

(1) the whole device adopts 4 independent lifting mechanisms and rotating mechanisms to be matched with a bed sheet wound on a rotating pipe, so that a person with mobility disability can be assisted to turn over, bedsores caused by long-term bed rest of the person with mobility disability are avoided, the structure is simple, the bed frame is suitable for different bed frame bodies, and the installation is simple and convenient;

(2) the nursing bed with the height of the backrest plate adjusted by adopting the one-way joint and the movable mechanism in a matching way can assist people who have inconvenient actions to lie on the bed for eating, reading, watching TV and the like; the one-way section is locked through the drawable rotating mechanism, and the turning-over and half-lying functions are realized simultaneously;

(3) the modular design is adopted, the occupied space is small, and the transportation is convenient;

(4) the bed body is suitable for bed bodies with different sizes and structures, can be assembled and spliced on site, and is simple and convenient to install;

(5) the structure is simple, the design is ingenious, and the effect is obvious;

(6) according to the type of the adopted nursing bed and the actual requirements, if a back rest plate, a leg rest plate and/or a footrest are required to be arranged, one-way sections can be correspondingly added, the nursing bed is flexible and changeable, various use requirements are met, and the practicability is high;

(7) the manufacturing is simple, the processing and the assembly are easy, the cost is low, the practicability is high, and the method is suitable for large-scale popularization.

The foregoing description of the specific embodiments of the invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes and modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
