Description

Multifunctional nursing bed and control method thereof Technical Field The invention relates to the technical field of nursing beds, in particular to a multifunctional nursing bed and a control method thereof. Background The nursing bed is a product for assisting the nursing-grade patients to lie up and defecation, and mainly aims at the problems that the crowd comprises nursing-grade patients with inflexible actions, postoperative nursing, muscle weakness, moderately severe disability, long-term bedridden, high-position paralysis and the like, and the patients can cause muscle degeneration and the like due to long-term bedridden patients. With the development of medical instruments, the existing nursing bed can be folded basically, for example, a back leaning plate can be lifted upwards, so that a patient can lean on the nursing bed conveniently, and the posture of the nursing bed can be adjusted to be more comfortable. The structure of the existing nursing bed is like a nursing bed for urology department disclosed in 10 and 15 days of 2021 in Chinese patent publication No. CN112426299B, but the upper bed frame of the existing nursing bed can not rotate horizontally, so that patients with difficult bed taking out can not conveniently take out the nursing bed, certain difficulty is brought to the patient taking out the nursing bed, the legs of the patient can not be automatically lifted, and the lying posture of the patient can not be automatically adjusted. Therefore, the applicant provides a new technical scheme for consumers to select to use by improving and perfecting the structure and combining the prior art. Disclosure of Invention A first object of the present invention is to provide a multifunctional nursing bed which is converted into a back rest chair, has a leg lifting function, and is convenient for a patient to get on and off the bed. The first eyesight of the invention is realized in the following way: The utility model provides a multifunctional nursing bed, including the head of a bed, the bed tail, go up the bedstead, lower bedstead, rotary drive device and end bedstead, go up and be equipped with the mattress on the bedstead, go up the top of bedstead level locating lower bedstead, go up the bedstead and use the vertical line to rotate as the pivot and locate the top of bedstead down, the one end of bedstead is located down to the head of a bed, the other end of bedstead is located down, lower bedstead is located on the end bedstead, rotary drive device locates down on the bedstead, and drive and go up bedstead horizontal rotation, go up the bedstead and include the back frame, the waist frame, lift leg rest, back upset drive device and lift leg drive device, back frame, the waist frame, lift leg rest sets gradually the level on lower bedstead, back frame, waist frame, lift leg rest and lift leg frame and on the horizontal direction parallel and level, back frame, waist frame, lift leg frame horizontal rotation locates down on the bedstead, back upset drive device locates on the waist frame, and drive lift leg frame and overturn from top to bottom. The invention uses the rotary driving device to drive the upper bed frame to horizontally rotate, and simultaneously uses the backrest overturning driving device to drive the backrest frame to overturn up and down, thereby facilitating the patient to get on or off the bed or changing the rest posture of the patient. The upper bed frame is controlled to rotate through the rotary driving device, and the force arm of the rotary driving device is longer and saves more labor. In addition, the back rest and the leg lifting frame are driven by the back rest overturning driving device and the leg lifting driving device respectively, so that the back and the legs of a patient can be lifted, a doctor or a nurse can conveniently treat the patient, the posture of the patient on a nursing bed can be changed, and the body of the patient can be quickly recovered. Therefore, the upper bedstead can be changed into a backrest chair and can be flattened, so that the functions of sitting, sleeping and leg lifting are realized. The present invention can be further improved as follows. The fixed end of the rotary driving device is rotationally connected with the lower bedstead, the telescopic end of the rotary driving device is rotationally connected with the upper bedstead, and the telescopic end of the rotary driving device is eccentrically arranged with the rotating shaft of the upper bedstead. The leg lifting frame comprises a lower leg frame, a leg lifting connecting rod and a foot supporting frame, the waist frame, the lower leg frame and the foot supporting frame are sequentially hinged, the leg lifting connecting rod is rotationally arranged at the bottom of the waist frame, the telescopic end of the leg lifting driving device is rotationally connected with one end of the leg lifting connecting rod, the other end of the leg lifting connecting rod is slidingly
