Intelligent electric nursing bed with adjustable slope

Abstract

The present invention provides an intelligent electric nursing bed with adjustable slope, which belongs to the technical field of medical equipment. A modular steel wire array solution is adopted to divide the entire mattress into several independently controllable areas. Through the combined action of multiple motors in the horizontal and vertical directions, the softness of different blocks of the mattress can be arbitrarily controlled. When the user lies on the mattress, under the action of gravity, the mattress has low flexibility in places where the steel wire tension is large, and high softness in places where the steel wire tension is small. In this way, a horizontal or vertical slope will be formed in the places with high softness relative to the places with low softness. The horizontal slope helps the user to complete the action of getting up, and the vertical slope helps the user to complete the action of turning over. At the same time, the legs of the bed body are set to a telescopic mode, and the linear motor provides power for the lifting of the bed body. In the case of adding a split bed body, the switching between the bed mode and the chair mode can be completed by controlling the lifting height of the motors at the head and tail ends.

Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an intelligent electric nursing bed with adjustable slope. Background Art

[0002] The traditional design of nursing beds integrates the required multiple nursing functions into one. This method is barely acceptable for nursing beds with simpler functions, but it has great disadvantages for nursing beds that need to realize multiple complex functions. It not only increases the complexity of product structure design, but also has a large number of possible interferences between multiple mechanisms. The assembly process is relatively complicated, which has a direct impact on installation, maintenance, and function expansion. The cost of processing, manufacturing, assembly, debugging, and later maintenance has also increased significantly. The traditional overall design concept is a great obstacle to product development. Summary of the invention

[0003] The technical task of the present invention is to solve the deficiencies of the prior art and provide an intelligent electric nursing bed with adjustable slope.

[0004] The core idea of ​​the present invention is: adopting a modular steel wire array solution to divide the entire mattress into several independently controllable areas. Through the combined action of one or more motors in the horizontal and vertical directions, the softness of different areas of the mattress can be arbitrarily controlled. When the user lies on the mattress, under the action of gravity, the mattress has low flexibility where the steel wire tension is large, and high softness where the steel wire tension is small. In this way, a horizontal or vertical slope can be formed in the soft area relative to the soft area. The horizontal slope helps the user to get up, and the vertical slope helps the user to turn over. At the same time, the legs of the bed are set to a telescopic mode, and the linear motor provides power for the lifting of the bed. By controlling the lifting height of the motors at the head and tail ends, the split bed can be folded and deformed, and the switching between bed mode and chair mode can be completed.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A smart electric nursing bed with adjustable slope, comprising a transverse active roller group and a longitudinal active roller group, wherein the transverse active roller group comprises a first transverse roller, a second transverse roller and a third transverse roller, and the longitudinal active roller group comprises a first longitudinal roller, a second longitudinal roller and a third longitudinal roller, a transverse steel wire is installed on the transverse active roller group, and the transverse active roller group is connected to a transverse driven roller group through the transverse steel wire, a longitudinal steel wire is installed on the longitudinal active roller group, and the longitudinal active roller group is connected to a longitudinal driven roller group through the longitudinal steel wire, and the transverse active roller group, the longitudinal active roller group, the longitudinal driven roller group and the transverse driven roller group are connected. The center of the movable roller group passes through the fixed shaft and is installed on the push rod through the fixed shaft. The push rod is installed on the weight sensor. The weight sensor is installed on the motor mover through the base. The motor mover is a linear motor mover. The linear motor mover is composed of an iron core and a coil formed by stacking silicon steel sheets. The motor mover is installed on the side of the guide column through a guide rail and a slider. The motor stator is installed at the bottom of the motor mover. The motor stator is a permanent magnet composed of a set polarity and pole pitch. A motor shield is installed on the guide column; both ends of the fixed shaft are fixed on the push rod.

[0007] Bearings are installed between the transverse active roller group and the longitudinal active roller group and the fixed shaft, a driven pulley is installed at one end of the first transverse roller and the first longitudinal roller, and a transverse clutch and a longitudinal clutch are installed at the other end of the first transverse roller and the first longitudinal roller respectively; wire grooves are opened on the transverse active roller group and the longitudinal active roller group, and a wire tube passes through the fixed shaft.

[0008] The transverse clutch and the longitudinal clutch include an electromagnet, a clutch stator and a clutch mover. The clutch stator is fixed to one end of the first transverse roller and the first longitudinal roller. The clutch mover is fixed to one end of the second transverse roller and the second longitudinal roller. The clutch mover is installed in a guide sleeve. The electromagnet is fixed on a fixed shaft. A spring is installed between the electromagnet and the clutch mover.

[0009] There are rubber pads on the transverse steel wire and the longitudinal steel wire, and the rubber pads are fixed on the top rod through a pull ring.

[0010] The driven pulley is connected with the driving pulley through a synchronous toothed belt. The driving pulley is installed on the output shaft of the transverse motor and the longitudinal motor. The transverse motor and the longitudinal motor are installed on a mandrel, and a pulley guard is installed on the mandrel.

[0011] The intelligent electric nursing bed with adjustable slope of the present invention has the following beneficial effects compared with the prior art:

[0012] Compared with the traditional hard mattress, the flexible tensioning and contracting mechanism designed in the present invention can give the user a comfortable covering feeling. Patients with spinal injuries or lumbar injuries can lie on their backs directly on the rubber pad, avoiding the painful experience caused by lying on the bed for a long time.

[0013] The designed split control module divides the entire mattress into several independently controllable areas. Through the combined action of one or more motors in the horizontal and vertical directions, the softness of different areas of the mattress can be arbitrarily controlled, thereby helping the user to turn over and get up. Since flexible steel wires and rollers are used as action execution parts, no impact damage to the user's body will be caused during the operation.

[0014] When a traditional nursing bed switches from a lying position to a sitting position, the back of the human body will slide relative to the backboard surface from bottom to top. Conversely, when the backboard changes from a sitting position to a lying position, the back of the human body will slide relative to the backboard surface from top to bottom. The mechanism designed in the present invention can ensure that the bed body is tightly supported and fits the human body movement by controlling the longitudinal steel wire of the user's upper limbs to remain unchanged and the longitudinal steel wire of the lower limbs to extend under the premise of the transverse steel wire extension.
