Description

multifunctional nursing bed

technical field

Background technique

Automatic nursing bed products have entered the field of medical care and have been practiced for quite a long time, and have a very high usage rate in the field of advanced medical care and elderly care. At present, most of the nursing bed equipment has the function of automatically helping the user turn sideways and lift the back, and some equipment also has the function of transforming into a wheelchair. However, many nursing beds cannot realize rollover and back support at the same time, or in the process of switching between sideways and back up states, they need to go through the process of lying flat, which cannot make a smooth transition, which affects the user experience. Furthermore, when some nursing beds are transformed into wheelchairs, their lateral width does not change, so it is difficult to pass through narrow areas such as ordinary doorways and elevators in reality, which reduces the value of outdoor activities expected to be achieved by deformed wheelchairs. In order to solve this problem, the nursing bed simply reduces the lateral width of the bed, which reduces the sleeping area and affects the user experience.

The left middle bed board mechanism and the right middle bed board mechanism installed at the left and right ends of the middle middle bed board mechanism rotate around the X axis. The X axis rotates the right front bed board mechanism installed in the front end of the right middle bed board mechanism, and rotates the middle front bed board mechanism installed in the front end of the middle bed board mechanism around the X axis.

The left rear deck mechanism, the middle rear deck mechanism, the right rear deck mechanism, the left middle deck mechanism, the middle middle deck mechanism, the right middle deck mechanism, the left front deck mechanism, the middle front deck mechanism, and the right front deck mechanism. pattern arrangement. The structure of the left rear bed board mechanism and the right rear board board mechanism are the same and are symmetrically arranged at the left and right ends of the nursing bed. The structure of the right front bed plate mechanism is identical and symmetrically arranged at the left and right ends of the nursing bed.

The bed boards of the right rear bed board mechanism, the bed boards of the right middle bed board mechanism, the bed boards of the left rear bed board mechanism and the bed boards of the left middle bed board mechanism are all provided with longitudinal telescopic components. The end of the longitudinal telescopic assembly is provided with a rotating assembly that rotates around the Y axis. The rotating assembly at the right rear bed board mechanism and the rotating assembly at the right middle bed board mechanism are installed together to rotate around the X axis. The rotation at the left rear bed board mechanism The assembly and the rotating assembly at the left middle bed board mechanism are installed together in a rotational manner around the X axis. Take the right rear bed board mechanism and the right middle bed board mechanism as a column for illustration: the bed board of the right rear bed board mechanism is provided with a longitudinal telescopic assembly, and the front end of the longitudinal telescopic assembly is provided with a rotating assembly, and the rotating assembly can take the axis in the Y-axis direction as Center line, do spin movement; the bed plate of the right middle bed plate mechanism is provided with a longitudinal telescopic assembly, and the rear end of the longitudinal telescopic assembly is provided with a rotating assembly. Rotary movement; the rotating assembly at the right rear bed board mechanism can rotate relative to the rotating assembly at the right middle bed board mechanism with the axis in the X-axis direction as the center line.

As shown in Fig. 3 and Fig. 4, the longitudinal telescopic assembly includes a telescopic device and a slider; the bed boards of the right rear bed board mechanism, the bed boards of the right middle bed board mechanism, the bed boards of the left rear bed board mechanism and the bed boards of the left middle bed board mechanism are all provided with The chute, the slider is slidably installed on the chute, that is, the slider is placed in the chute, and the slider can slide in the chute, one end of the expander is connected to the bed board, and the other end of the expander is connected to the slide On the block, when the retractor is extended or retracted, it can drive the slider to move in a straight line in the chute. Multiple chutes can be set on the bed board, and the same number of longitudinal telescopic components can be set accordingly. In theory, a bed board mechanism can only be provided with one chute, and one longitudinal telescopic component can be set correspondingly, for example: the bed board of the right rear bed board mechanism and the right middle The bed boards of the bed board mechanism all have only one chute, and are also provided with a longitudinal telescopic assembly. A bed board mechanism of the nursing bed is provided with a plurality of chutes and a plurality of longitudinal telescopic components. As shown in Figure 10 and Figure 11, when the left rear bed mechanism, the middle rear bed mechanism, and the right rear bed mechanism rotate around the X-axis together (turn up), the telescopic device of the longitudinal telescopic component will push the slider to slide on the chute , so as to ensure the smooth realization of the flipping action. As shown in Figure 12, when the left rear deck mechanism, the middle rear deck mechanism, and the right rear deck mechanism are turned up to the vertical state together, as shown in Figure 15 and Figure 16, the right middle deck mechanism rotates around the Y axis (downward Flip), when the right rear bed board mechanism rotates around the Z axis (flip backward), the distance that the telescopic device of the longitudinal telescopic component pushes the slider moves varies from long to short, and close to the edge of the nursing bed, the slider stretches the longest, that is, the sliding The block moves the maximum distance. The structure of the longitudinal telescopic assembly is simple, but it can realize the left rear bed mechanism, the middle rear bed mechanism and the right rear bed mechanism to turn up together, and can realize the left middle bed mechanism and the right middle bed mechanism to turn down, and the left rear bed mechanism and the right The rear deck mechanism flips backwards.

The shapes of the two hinged blocks are not exactly the same. It is only necessary to ensure that the two hinged blocks can rotate around the X axis, so that the left rear bed mechanism, the middle rear bed mechanism, and the right rear bed mechanism are turned upward together. Simultaneously when the left rear deck mechanism, the middle rear deck mechanism and the right rear deck mechanism are turned up to the vertical state together, the hinge block of the right rear deck mechanism is in a vertical state, and the hinge block of the right middle deck mechanism is in a horizontal state. During the process of turning the right middle bed board mechanism downward and the right rear bed board mechanism backward, the hinge block of the right rear bed board mechanism and the hinge block of the right middle bed board mechanism will not rotate. When the hinge block rotates, the slider will rotate (non-spin) around the axis in the Z-axis direction.
