Describe one use process of the present invention below in conjunction with accompanying drawing:

Taking a patient in a lying state as an example, when the patient needs to turn over sideways, he only needs to activate the electric push rod 11 for turning over, so that the electric push rod 11 for turning over is extended, and then pushes the turning plate 9 to turn up, so as to pass the upward turning push rod 11 . The turning board 9 is used to assist the patient to complete the lateral turning action. After the patient is turned over, the electric push rod 11 for turning over is controlled to reset, so that the turning plate 9 also returns to the initial state.

When the patient needs to get up and sit up, he only needs to activate the back lift electric push rod 5 to extend the back lift electric push rod 5, and then push the back plate 3 to turn up, so as to assist the patient to get up through the raised back plate 3 Sitting action. However, only with the assistance of the back plate 3, the patient's body position will be lower, which will cause a certain gap between the patient's waist and the back plate 3, which will cause the patient's waist to hang in the air, thereby causing stress concentration in the waist. If the sitting position is maintained for a long time, it will inevitably cause damage to the patient's waist. In order to solve the above problems, the body position of the patient can be fine-tuned through the hip plate adjustment mechanism to eliminate the gap between the patient's waist and the back plate 3 .

Taking the fine adjustment of the horizontal position of the hip plate 17 as an example, the electric push rod 21 for adjusting the height of the hip plate needs to be locked first, so that the freedom of linear movement of the moving series shaft 22 is limited, so that the first hip plate slider 23 is locked. The relative position of the second hip plate slider 24 on the hip plate slide rail 25 is limited. At this time, adjust the level of the hip plate to adjust the telescopic amount of the electric push rod 20. Under the reaction force, the hip plate slide rail 25 and the first hip plate slide rail 25 The plate slider 23 and the second hip plate slider 24 will produce relative horizontal displacement, so that the hip plate 17 is synchronously displaced horizontally, and finally the fine adjustment of the horizontal position of the hip plate 17 is realized.

Taking the fine adjustment of the height position of the hip plate 17 as an example, the electric push rod 20 for horizontal adjustment of the hip plate needs to be locked first, so that the position of the second hip plate slider 24 on the hip plate slide rail 25 is limited. Adjusting the height of the hip plate and adjusting the telescopic amount of the electric push rod 21 can simultaneously realize the horizontal linear movement of the moving serial axis 22 and the first buttock plate slider 23, thereby making the first hip plate link 18 and the second hip plate link 19. When the cross angle is changed, the height of the first hip plate slider 23 is changed in a horizontal straight line, so that the height position of the hip plate 17 is changed, and finally the fine adjustment of the horizontal position of the hip plate 17 is realized.

Due to the physical differences between patients, it is necessary to adjust the position of the leg plate 27 to ensure the comfort of the patient. Specifically, by adjusting the telescopic amount of the electric push rod 29 of the leg plate, the leg plate link 28 can be oscillated. The linkage between the leg plate 27 and the foot plate 30 is realized by the swinging of the leg plate link 28 until the leg plate 27 is adjusted to a comfortable position for the patient.

The solutions in the embodiments are not intended to limit the scope of the patent protection of the present invention, and all equivalent implementations or modifications that do not depart from the present invention are included in the scope of the patent of this case.
