[0035] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] This utility model provides a nursing bed, including a bed frame body and a control structure. The bed frame body includes multiple frames to meet the function switching of different forms. The control structure controls the operation of the drive structure to meet the automatic switching of various forms, such as backrest lifting, leg lifting, flipping, bedpan switching, one-button chair conversion, and other function switching.

[0037] The following description, in conjunction with the accompanying drawings, details the components of the nursing bed provided in the embodiments of this utility model, the positional relationships between the components, and the connection relationships.

[0038] like Figures 1 to 10 As shown in the embodiment of this utility model, the bed frame body 1 includes a position switching structure 11 and a drive structure 12. The drive structure 12 is connected to the position switching structure 11 and is used to drive the position switching structure 11 to perform form switching. The control structure 2 includes a control terminal 21 and a controller 22. The controller 22 is configured to receive control signals from the control terminal 21 and control the drive structure 12 to operate in a set mode.

[0039] For example, the controller 22 is located at the bottom of the bed frame body 1 and at one side end. The controller 22 includes a power interface 221 and a motor interface 222. The power interface 221 is connected to the power supply, and the motor structure is connected to the motor of each drive structure 12.

[0040] For example, the control terminal 21 communicates with the controller 22 via wired or wireless means. When using a wired connection, the controller 22 also includes a control terminal interface 223.

[0041] For example, the control terminal 21 is an independent remote control device, which includes control buttons 211. By pressing the control buttons 211, control signals are sent to the controller 22. The control buttons 211 may include backrest lifting buttons, leg lifting buttons, flipping control buttons, bedpan control buttons, automatic turning buttons, chair turning buttons, and reset buttons.

[0042] In this embodiment of the invention, the control signal is not limited to the sending method of the control button 211. For example, voice control can also be used, whereby the control terminal 21 receives voice control signals from the patient or caregiver and sends control signals to the controller 22 based on the voice signals. Alternatively, for example, the control terminal 21 can also be an existing mobile terminal, such as a mobile communication device, where control signals are sent to the controller 22 by performing button control or voice control on the mobile terminal.

[0043] The control terminal 21 and controller 22 can operate a single drive structure 12 or drive multiple drive structures 12. When a single drive structure 12 is running, it can switch between a single mode such as backrest lifting, leg lifting, or flipping. When multiple drive structures 12 are running, they can switch between multiple modes simultaneously, such as a chair mode, which includes backrest lifting and leg lowering.

[0044] Continue to refer to Figures 1 to 10As shown in the embodiment of this utility model, the position switching structure 11 includes a back frame 111, a leg frame 112, a toilet bowl support 113, and a flipping frame 115, etc. The driving structure 12 includes a first linear driving device 121, a second linear driving device 122, a third linear driving device 123, and a fourth linear driving device 124, etc., which can realize various functions through form switching. The following is a detailed description of each functional form.

[0045] In this embodiment of the present invention, the drive structure 12 includes a first linear drive device 121; the back frame 111 is rotatably connected to the bed frame body 1, the back frame 111 is fixedly connected to the first rotating frame 1111, and the telescopic structure of the first linear drive device 121 is rotatably connected to the first rotating frame 1111.

[0046] The telescopic structure of the first linear drive device 121 can extend or shorten, and in conjunction with the first rotating frame 1111, the tilting angle of the back frame 111 can be adjusted. For example, a lifting bracket 1112 is provided below the back frame 111. One end of the lifting bracket 1112 is provided with a roller 1113, and the other end is provided with a first shaft 1114. Both ends of the first shaft 1114 are rotatably connected to the bed frame body 1. The first rotating frame 1111 and the first shaft 1114 are rotatably connected. In the initial state, the lifting bracket 1112 is located below the back frame 111. As the telescopic structure of the first linear drive device 121 shortens, the first shaft 1114 is continuously subjected to a rotational force. Under the action of this force, the lifting bracket 1112 moves closer to the back frame 111 and gradually lifts the back frame 111. During the lifting process, the roller 1113 slides relative to the back of the back frame 111.

[0047] Once the back frame 111 has been raised to a certain height, the first linear drive device 121 stops operating, keeping the back frame 111 in its current position. When it is necessary for the back frame 111 to descend, the first linear drive device 121 moves in the opposite direction until it reaches the starting position.

[0048] In this embodiment of the utility model, the position switching structure 11 includes a leg frame 112, and the driving structure 12 includes a second linear driving device 122; the leg frame 112 is rotatably connected to the bed frame body 1, the leg frame 112 is fixedly connected to the second rotating frame 1123, and the telescopic structure of the second linear driving device 122 is rotatably connected to the second rotating frame 1123.

[0049] The leg frame 112 may include one frame structure or two frame structures. The driving method of one frame structure may be the same as that of the back frame 111, which will not be described in detail here.

[0050] When the leg frame 112 includes two frame structures, namely, the leg frame 112 includes a first leg frame 1121 and a second leg frame 1122, the first leg frame 1121 and the second leg frame 1122 are rotatably connected, and the side of the first leg frame 1121 away from the second leg frame 1122 is rotatably connected to the bed frame body 1; the second rotating frame 1123 includes a connecting rod 11231, a connecting frame 11232 and a support frame 11233, one end of the connecting rod 11231 is rotatably connected to the bed frame body 1, and the other end is rotatably connected to the support frame 11233, the connecting frame 11232 is fixedly mounted on the connecting rod 11231 and is rotatably connected to the telescopic structure of the second linear drive device 122; the support frame 11233 is fixedly connected to the bottom of the second leg frame 1122 and is used to support the second leg frame 1122.

[0051] The first leg support 1121 and the second leg support initially remain flush with the bed frame body 1. When it is necessary to raise the height of the first leg support 1121 and the second leg support 1122, the telescopic structure of the second linear drive device 122 extends, the drive link 11231 is gradually raised, and the support frame 11233 is raised simultaneously, thereby raising the first leg support 1121 and the second leg support 1122. In this state, when the patient is lying flat, the lower legs can be partially supported. When it is necessary to lower the height of the first leg support 1121 and the second leg support 1122, the telescopic structure of the second linear drive device 122 shortens from the initial position, the drive link 11231 is gradually lowered, and the support frame 11233 is lowered simultaneously, thereby lowering the first leg support 1121 and the second leg support 1122. In this state, when the patient is sitting, the lower legs and feet can be supported.

[0052] In this embodiment of the utility model, the position switching structure 11 includes a bedpan support 113, and the driving structure 12 includes a third linear drive device 123; the bedpan support 113 includes a bedpan frame body 1131, a support frame body 1132, and a driven link 1133, the bedpan frame body 1131 and the support frame body 1132 are connected by the driven link 1133, and the bedpan frame body 1131 and the support frame body 1132 are respectively rotatably connected to the bed frame body 1; the support frame body 1132 is fixedly connected to a third rotating frame 1134, and the telescopic structure of the third linear drive device 123 is rotatably connected to the second rotating frame 1123;

[0053] A second shaft 1135 is fixedly connected to one side of the bed frame body 1131. The two sides of the second shaft 1135 are rotatably connected to the bed frame body 1. A third rotating frame 1134 is fixedly connected to the second shaft 1135. The two sides of the support frame body 1132 each include at least two movable rods 1136. One end of the movable rod 1136 is rotatably connected to the bed frame body 1, and the other end is rotatably connected to the support frame body 1132. The bed frame bracket 113 includes two driven connecting rods 1133. The two driven connecting rods 1133 are rotatably connected to one of the movable rods 1136 on the same side.

[0054] The bed frame body 1 includes a toilet hole 114. When the toilet hole 114 is not in use, the support frame body 1132 needs to fill the toilet hole 114 to prevent it from collapsing. When in use, the support frame body 1132 needs to be removed and the bedpan holder body 1131 moved to a designated position below the toilet hole 114. This designated position is such that the bedpan is directly opposite the toilet hole 114, and the end of the bedpan is fitted against the bottom of the toilet hole 114 to prevent excrement from splashing. Specifically:

[0055] In the initial state, the support frame body 1132 is filled into the urinal hole 114 (the urinal hole 114 is in a non-use state by default). The telescopic structure of the third linear drive device 123 extends, simultaneously causing the third rotating frame 1134 to drive the second shaft 1135 to rotate. The support frame body 1132 rotates synchronously with the second shaft 1135, thereby withdrawing the support frame body 1132 from the urinal hole 114. At the same time, as the support frame body 1132 rotates, the driven connecting rod 1133 pulls the movable rod 1136 to move, raising the bedpan frame body 1131 to a certain height and below the urinal hole 114. After the patient finishes urinating, the telescopic structure of the third linear drive device 123 moves in the opposite direction, i.e., it retracts and resets. The support frame body 1132 fills into the urinal hole 114, and the bedpan frame body 1131 descends to the initial position, allowing the caregiver to pick up and put down the bedpan.

[0056] In this embodiment of the present invention, the position switching structure 11 includes a flipping frame 115, and the driving structure 12 includes a fourth linear driving device 124; the flipping frame 115 is rotatably connected to the bed frame body 1, the flipping frame 115 is fixedly connected to the fourth rotating frame 1154, and the telescopic structure of the fourth linear driving device 124 is rotatably connected to the fourth rotating frame 1154.

[0057] The flip frame 115 may include one frame structure or two frame structures. The driving method of one frame structure may be the same as that of the back frame 111, which will not be described in detail here.

[0058] When the flip frame 115 includes two frame structures, namely, the flip frame 115 includes a first flip frame 1151, a second flip frame 1152 and a drive rod 1153, the first flip frame 1151 and the second flip frame 1152 are rotatably connected, the middle part of the drive rod 1153 is fixedly connected to a third shaft 1355, the two ends of the third shaft 1355 are rotatably connected to the bed frame body 1, and the rods on both sides of the middle part of the drive rod 1153 are respectively connected to the first flip frame 1151 and the second flip frame 1152; one end of the fourth rotating frame 1154 is fixedly connected to the third shaft 1355, and the other end is rotatably connected to the telescopic structure of the fourth linear drive device 124.

[0059] In the initial state, both the first and second tilting frames 1151 and 1152 are flush with the bed frame body 1. When the first tilting frame 1151 needs to be lifted, the telescopic structure of the fourth linear drive device 124 extends, driving the third shaft 1355 to rotate. Simultaneously, the drive rod 1153 is tilted, causing one end of the drive rod 1153 to be lifted. This end simultaneously lifts the first tilting frame 1151 to a certain angle, thereby enabling the patient to be turned over. Similarly, to tilt the second tilting frame 1152, the telescopic structure of the fourth linear drive device 124 is shortened, causing the other end of the drive rod 1153 to be lifted.

[0060] In this embodiment of the invention, multiple frame structures can be stacked on the bed frame body 1, or they can be shared to achieve corresponding functions. For example, the back frame 111 and part of the flip frame 115 are shared. The flip angles of the back frame 111 and the flip frame 115 are different, so they do not affect each other when performing the corresponding flipping action. However, for the stacked or shared structures, they cannot simultaneously perform both functions. For example, because the back frame 111 and part of the flip frame 115 are shared, the nursing bed cannot perform the back lifting function and the flipping function at the same time. By adopting the above-mentioned frame structure arrangement, a more reasonable control of the structural space of the bed frame body 1 can be achieved.

[0061] In this embodiment of the present invention, the first linear drive device 121, the second linear drive device 122, the third linear drive device 123, and the fourth linear drive device 124 can be linear screw structures, and the extension or shortening of the linear drive device can be adjusted by controlling the forward or reverse rotation of the linear screw; wherein, the first linear drive device 121, the second linear drive device 122, the third linear drive device 123, and the fourth linear drive device 124 can also be other linear drive forms, such as cylinder structures, etc. In this embodiment of the present invention, the drive form of the linear drive device is not limited.

[0062] In this embodiment of the utility model, the rotating connection structure includes a rotating shaft connected to the connected structure via an ear plate or a support plate, thereby enabling the two structures to rotate relative to each other.

[0063] Continue to refer to Figures 1 to 10 As shown in the embodiment of this utility model, the "one-click chair conversion" function can be realized, that is, the first linear drive device 121 and the second linear drive device 122 operate synchronously, the first linear drive device 121 raises the back frame and the second linear drive device 122 lowers the leg frame 112, thereby completing the switch from the nursing bed to the chair form; similarly, the "one-click restore" function can also be realized, the first linear drive device 121 and the second linear drive device 122 operate in opposite directions to restore to the original position, and switch from the chair form to the nursing bed form.

[0064] This utility model provides a nursing bed in which the position-changing structure 11 of the drive structure 12 can be changed during use, thereby completing the form switching (functional mode switching) of the nursing bed, such as adjusting the back height, leg height, or tilting. The drive structure 12 can be controlled by a control terminal 21. The control terminal 21 sends control signals, and the controller 22 controls the drive structure 12 to perform actions such as rotation direction and start / stop time according to the type of control signal. This utility model's technical solution, while meeting the multi-functionality requirements of the nursing bed, also provides a simpler and faster control method, facilitating operation by patients or caregivers.
