Description

Technical Field

[0001] The present disclosure relates to the technical field of nursing equipment, and in particular to a turning nursing bed. Background Art

[0002] A turning nursing bed is a nursing bed, which comprises a bed frame and a bed surface placed on the bed frame, wherein a mattress is laid on the bed surface for patients to lie down, but it is difficult for patients to turn over sideways. Therefore, in order to meet the needs of patients, a nursing bed that can assist in turning over is needed. Existing nursing beds that can assist in turning over are usually two-fold turning beds, that is, the bed surface is designed to be a left bed surface and a right bed surface that are hinged to each other, the left bed surface and the right bed surface are of the same size, and two sets of electric push rods are used to respectively control the left bed surface and the right bed surface, so as to assist patients in turning over to the left side and the right side.

[0003] However, when this kind of two-fold turning bed assists in turning over, the left bed surface or the right bed surface usually forms a turning axis in the middle of the patient's body, which can only drive half of the body to turn over. The part that can be driven to turn over is small, resulting in poor comfort when turning over, which reduces the user experience. In addition, the existing turning drive parts require two sets of drive parts to drive the two left bed surfaces and the right bed surfaces to turn over respectively, which makes the production cost of the turning nursing bed high; moreover, in order to ensure the stability of the bed surface, it is usually necessary to lock and fix the bed surface. When driving the bed surface to turn over, the patient is required to first operate the locking part to perform the unlocking action, and then operate the drive part to perform the turning action, which makes the operation of the turning bed more complicated.

For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of this disclosure can be achieved, and this document is not limited here.

[0058] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0059] The following describes in detail the various embodiments of the present application in conjunction with the accompanying drawings.

[0060] For ease of explanation, Figure 1 and Figure 2 A three-dimensional coordinate system is added, the direction of the X-axis is the first direction, that is, the setting direction of the first bed surface 1211, the second bed surface 1212 and the third bed surface 1213, the direction of the Z-axis is the second direction, that is, the arched direction of the second bed surface 1212, and the direction of the Y-axis is the third direction, that is, the direction in which the axis extends, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0061] Please also read Figure 1 and Figure 2The present embodiment provides a turning nursing bed, which includes a bed frame assembly 11, a bed surface assembly 12 and a driving mechanism 13. The bed surface assembly 12 includes a folding bed surface 121 carried on the bed frame assembly 11, the folding bed surface 121 is used to support the patient's waist, the folding bed surface 121 includes a first bed surface 1211, a second bed surface 1212 and a third bed surface 1213 arranged in sequence along a first direction, the second bed surface 1212 is rotatably connected to the third bed surface 1213 and the first bed surface 1211, specifically, the first bed surface 1211 and the third bed surface 1213 are both rotatably connected to the second bed surface 1212 through a pin shaft, the driving mechanism 13 includes a driving assembly 131 and a locking assembly 132, the driving assembly 131 is connected to the bed frame assembly 11 and the second bed surface 1212, the driving Component 131 is used to drive the locking component 132 to unlock the first connection end of the second bed surface 1212 and drive the second bed surface 1212 to arch at one end in the first direction along the second direction. Specifically, the first connection end is the pin shaft at the connection between the first bed surface 1211 and the second bed surface 1212, or / and, the driving component 131 is used to drive the locking component 132 to unlock the second connection end of the second bed surface 1212 and drive the second bed surface 1212 to arch at the other end in the first direction along the second direction. Specifically, the second connection end is the pin shaft at the connection between the third bed surface 1213 and the second bed surface 1212. When the locking component 132 unlocks the first connection end, the locking component 132 locks the second connection end. When the locking component 132 unlocks the second connection end, the locking component 132 locks the first connection end.

[0062] In the above-mentioned turning nursing bed, after the locking assembly 132 at the first connection end of the second bed surface 1212 is unlocked by the driving assembly 131, one end of the second bed surface 1212 is driven to arch upward in the first direction (i.e., in the direction from the bed frame assembly 11 to the bed surface assembly 12 in the second direction), so as to drive the patient to turn around the other end of the second bed surface 1212 to the third bed surface 1213. After the driving assembly 131 unlocks the locking assembly 132 at the first connection end of the second bed surface 1212, the other end of the second bed surface 1212 is driven to arch upward in the first direction (i.e., in the direction from the bed frame assembly 11 to the bed surface assembly 12 in the second direction), so as to drive the patient to turn around one end of the second bed surface 1212. The bed surface 1211 is turned to the first bed surface 1211 to assist the patient in turning over to the left or right side; in this way, the patient is pushed to turn over by the second bed surface 1212 which has a larger contact area with the patient's body and bears a larger weight, and the second bed surface 1212 turns over around the edge of the patient's body, thereby improving the comfort of the patient's turning over and improving the user experience. At the same time, only one set of driving components 131 is used to provide the patient with turning over in two directions, either to the left or to the right, thereby reducing the production cost of the turning nursing bed, and the unlocking and turning over of the folding bed surface can be performed by the patient at one time, thereby achieving the turning nursing bed with reduced production costs and more convenient operation on the basis of improving the user experience.

[0063] It can be understood that the first bed surface 1211, the second bed surface 1212 and the third bed surface 1213 are arranged in sequence along the first direction, so that the second bed surface 1212 is located between the first bed surface 1211 and the third bed surface 1213. When the patient lies on the folding bed surface 121, the second bed surface 1212 has a larger contact area with the patient and bears more of the patient's weight. Moreover, the turning axis of the second bed surface 1212 when pushing the patient to turn over is close to the edge of the human body, which makes the patient more comfortable and has a better experience when turning over.

[0064] Please also read Figure 3 and Figure 4In some embodiments, the driving assembly 131 includes a rotating shaft 1311, a first connecting rod 1312, a second connecting rod 1313, a toggle member 1314 and a driving member 1315. The rotating shaft 1311 extends along the third direction, and one end of the rotating shaft 1311 is rotatably connected to the bed frame assembly 11. The first connecting rod 1312 is movably arranged in the bed frame assembly 11, and one end of the first connecting rod 1312 is rotatably connected to one end of the second bed surface 1212 in the first direction, one end of the second connecting rod 1313 is rotatably connected to the other end of the first connecting rod 1312, and the other end of the second connecting rod 1313 is rotatably connected to the rotating shaft. 1311, the toggle member 1314 is connected to the rotating shaft 1311 and is used to toggle the second connecting rod 1313 to rotate around the rotating shaft 1311, the driving member 1315 is connected to the rotating shaft 1311 and the bed frame assembly 11, the driving member 1315 is used to drive the rotating shaft 1311 to rotate so as to drive the toggle member 1314 to toggle the second connecting rod 1313 to rotate around the rotating shaft 1311, and the connection between the first connecting rod 1312 and the second connecting rod 1313 is located on the side of the bed frame assembly 11 away from the bed surface assembly 12, so that the first connecting rod 1312 flips over and drives one end of the second bed surface 1212 in the first direction to arch along the second direction.

[0065] In this way, the rotating shaft 1311 is driven to rotate by the driving member 1315, and the toggle member 1314 rotates synchronously with the rotating shaft 1311 and drives the second connecting rod 1313 to rotate around the rotating shaft 1311, and the second connecting rod 1313 drives the first connecting rod 1312 to perform a flipping movement, so that one end of the first connecting rod 1312 pushes one end of the second bed surface 1212 in the first direction to arch along the second direction, thereby assisting the patient to turn over to one side. At the same time, the connecting rod structure formed by the first connecting rod 1312 and the second connecting rod 1313 is simple and easy to process, so as to reduce the cost of the turning nursing bed.

[0066] Please refer to the figure. In this embodiment, the driving member 1315 includes a linear driving body 1315a and a connecting body 1315b. One end of the connecting body 1315b is connected to the rotating shaft 1311. The other end of the connecting body 1315b is rotatably connected to one end of the linear driving body 1315a. The other end of the linear driving body 1315a is rotatably connected to the bed frame assembly 11. The linear driving body 1315a is used to drive the connecting body 1315b to drive the rotating shaft 1311 to rotate, so that the linear motion of the linear driving body 1315a is converted into the rotational motion of the rotating shaft 1311, so as to reduce the rotation speed of the rotating shaft 1311 and increase the torque of the rotating shaft 1311, so as to achieve the effect of deceleration and torque increase. Exemplarily, the linear driving body 1315a can be an electric push rod, a cylinder, or a hydraulic cylinder.

[0067] See also Figure 4In this embodiment, the driving assembly 131 also includes a third connecting rod 1316 and a fourth connecting rod 1317. The third connecting rod 1316 is movably arranged in the bed frame assembly 11. One end of the third connecting rod 1316 is rotatably connected to the other end of the second bed surface 1212 in the first direction. One end of the fourth connecting rod 1317 is rotatably connected to the other end of the third connecting rod 1316. The other end of the fourth connecting rod 1317 is rotatably connected to the rotating shaft 1311. The connection between the third connecting rod 1316 and the fourth connecting rod 1317 is located on the side of the bed frame assembly 11 away from the bed surface assembly 12. The toggle member 1314 is located between the second connecting rod 1313 and the fourth connecting rod 1317. The driving member 1315 is used to drive the rotating shaft 1311 to rotate so as to drive the toggle member 1314 to toggle the fourth connecting rod 1317 to rotate around the rotating shaft 1311, so that the third connecting rod 1316 drives the other end of the second bed surface 1212 in the first direction to arch along the second direction.

[0068] In this way, the rotating shaft 1311 is driven to rotate in the opposite direction through the driving member 1315, and the toggle member 1314 is driven to rotate synchronously to toggle the fourth connecting rod 1317 to rotate around the rotating shaft 1311. The fourth connecting rod 1317 drives the third connecting rod 1316 to perform a flipping motion and pushes the other end of the second bed surface 1212 in the first direction to arch along the second direction to assist the patient to turn over to the other side. At the same time, the connecting rod structure formed by the third connecting rod 1316 and the fourth connecting rod 1317 is simple and easy to process, so as to reduce the cost of the turning nursing bed.

[0069] In this embodiment, the driving assembly 131 also includes a reset torsion spring, which is sleeved on the rotating shaft 1311, and one end of the reset torsion spring abuts against the second connecting rod 1313, and the other end of the reset torsion spring abuts against the fourth connecting rod 1317. The elastic force released by the reset torsion spring is used to drive the second connecting rod 1313 to reset, and to drive the fourth connecting rod 1317 to reset.

[0070] See also Figure 3 In some embodiments, the bed frame assembly 11 includes a bed frame body 111, a diagonal support rod 112 and a supporting frame 113. The supporting frame 113 is connected to the bed frame body 111 and is used to support the bed surface assembly 12. A gap is formed between the bed surface assembly 12 and the bed frame assembly 11. The diagonal support rod 112 is arranged between the bed surface assembly 12 and the bed frame assembly 11, and one end of the diagonal support rod 112 is rotatably connected to the bed frame assembly 11, and the other end of the diagonal support rod 112 is rotatably connected to the bed frame body 111.

[0071] In this way, by arranging the supporting frame 113 between the bed frame body 111 and the bed surface assembly 12, a suspended state is formed between the bed frame body 111 and the bed surface assembly 12, which is beneficial to provide installation space when the bedding on the bed surface assembly 12 is fixed to the bed surface, thereby ensuring the beauty of the bed body. At the same time, by arranging the diagonal support rod 112, the bed surface assembly 12 is stably supported to avoid being pressed down and causing secondary injuries to the patient.

[0072] It is understandable that the edge position of the bedding laid on the bed surface assembly 12 needs to be fixed to the bed surface assembly 12 to prevent the bedding from falling off the bed surface assembly 12 when the bed surface assembly 12 is turned over. Therefore, by arranging the bed frame body 111 and the bed surface assembly 12 at intervals and forming a suspended space, it is beneficial to provide a fixed space for the bedding on the bed surface assembly 12.

[0073] In this embodiment, there are two groups of diagonal support rods 112, and the number of diagonal support rods 112 in each group is multiple. One group of diagonal support rods 112 is arranged between the first bed surface 1211 and the bed frame body 111, and the two ends of each diagonal support rod 112 are respectively rotatably connected to the first bed surface 1211 and the bed frame body 111; the other group of diagonal support rods 112 is arranged between the third bed surface 1213 and the bed frame body 111, and the two ends of each diagonal support rod 112 are respectively rotatably connected between the third bed surface 1213 and the bed frame body 111.

[0074] Please also read Figure 5 and Figure 6 In some embodiments, the bed surface assembly 12 further includes a positioning member 124, which is connected to the folding bed surface 121. The positioning member 124 is used to guide the folding bed surface 121 to return to the bed frame assembly 11, so that the folding bed surface 121 can be flipped back to its original position after the folding bed surface 121 performs the auxiliary turning action.

[0075] In this embodiment, a positioning groove is formed on the positioning member 124 , and the positioning groove is matched with the supporting frame 113 . When the supporting frame 113 enters into the positioning groove, the bed surface assembly 12 and the bed frame body 111 are positioned with each other.

[0076] Furthermore, the structure of the opening of the positioning groove is roughly V-shaped, so that the positioning groove can correct the position of the bed surface assembly 12, thereby improving the accuracy of resetting the folded bed surface 121 to the bed frame assembly 11.

[0077] In this embodiment, there are multiple positioning members 124, and the first bed surface 1211, the second bed surface 1212 and the third bed surface 1213 are all connected with positioning members 124. The multiple positioning members 124 are used to guide the first bed surface 1211, the second bed surface 1212 and the third bed surface 1213 to be positioned on the bed frame assembly 11, so as to achieve accurate resetting of the first bed surface 1211, the second bed surface 1212 and the third bed surface 1213.
