The working principle of the present invention is as follows: when the new type of fast steering and smooth moving nursing bed transfers patients, due to the complex terrain environment of the hospital, such as entering an elevator, entering a landslide, etc., due to the limitation of the turning radius, the nursing bed cannot be smoothly steered and moved. , in order to achieve the smooth transfer of patients, and the bottom surface of different areas of the hospital fluctuates greatly, causing severe vibration during the transfer process, which is not conducive to the recovery of the patient's condition. In order to solve the above problems, by rotating the nursing bed, because the limit steering wheel The function of the frame 4 and the supporting steering shaft 7 enables the nursing bed to achieve the purpose of in-situ steering, and the main damping spring 8 provided between the supporting steering shaft 7 and the supporting steering bearing sleeve 9 can compensate for the uneven transition of terrain in time. In order to further reduce the vibration during transfer, a small amount of vibration is offset by the secondary shock-absorbing spring column 22 set at the upper end of the shock-absorbing mounting plate 2, which ensures the treatment of the patient to the greatest extent. The transfer process is simple and efficient, and the patient can change the bed smoothly by synchronizing the electronically controlled lifting module and the hinge deformation bed turning module, so that the lifting motor 11 is powered to drive the driving gear 10, and the driving gear 10 drives the lifting gear 12. The lifting slider 15 on the worm 14 can only move up and down under the restriction of the lifting movable groove 16, which drives the upper bed plate 26 and the lower bed plate 25 to rise together, and then the fixed buckle 28 is uncovered. The upper bed plate 26 can be lifted up along the rotating drum 24, which is convenient for the patient to be transferred to the hospital bed in the ward. After the transfer is completed, the fixed buckle 28 is fastened to complete the purpose of smooth and efficient transfer, which overcomes the traditional mobile nursing bed. The imperfect design and poor tolerance of the hospital terrain result in obvious vibration during the patient transfer process, and the reversing operation cannot be realized in a narrow space, causing unnecessary obstacles to patients and medical staff, and solving the problem of traditional nursing care. When the bed is transferred to the patient, due to the level of the bed board, the transfer is difficult, and it is very easy to damage the patient and cause unnecessary damage. By integrating the functions of multi-level shock absorption, arbitrary steering and turning plate transfer, the present invention has novel structure and perfect function. Comprehensive, efficient transmission, convenient, fast and stable mobile steering, suitable for large-scale promotion and use.
