Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a turning device and a nursing bed. Background Technology

[0002] In medical and home care settings, nursing beds with turning functions have become crucial equipment for long-term bedridden paralyzed patients, postoperative rehabilitation patients, and elderly disabled individuals. These nursing beds achieve automated or semi-automated turning of patients through turning components, effectively reducing the intensity of manual turning and lowering the risk of health problems such as pressure sores and muscle atrophy caused by prolonged fixed positions, significantly improving care convenience and patient comfort.

[0003] However, in existing nursing beds with turning function, the movement trajectory of the turning component during the patient turning process depends entirely on the power output control of the drive mechanism. It lacks effective positioning and trajectory constraints, resulting in insufficient stability of the turning component during operation. During the turning process, the flip-over bed board is prone to lateral displacement, up-and-down shaking or local jamming. Summary of the Invention

[0004] This utility model provides a turning device and a nursing bed to solve the problems of insufficient stability of the turning component during operation, and the easy occurrence of lateral displacement, up-and-down shaking or partial jamming of the flip-up bed board during the turning process.

[0005] Firstly, this utility model provides a turning-over device, comprising: A bed board having a first board group, a second board group, and a third board group, wherein the first board group and the third board group are respectively disposed on both sides of the second board group, and the second board group is hinged to the first board group and the third board group respectively; The drive assembly includes a first swing arm and a second swing arm. One end of the first swing arm is hinged to one side of the second plate group, and the other end of the first swing arm is rotatably disposed below the bed board. One end of the second swing arm is hinged to the other side of the second plate group, and the other end of the second swing arm is rotatably disposed below the bed board. A guide assembly is disposed at the bottom of the first plate group and the third plate group respectively, and the guide assembly is connected to the first plate group and the third plate group respectively to provide guidance when the first plate group or the third plate group moves.

[0006] Beneficial effects: The precise guidance of the guide components effectively prevents lateral shifts, vertical swaying, or localized jamming of the first and third plate groups during movement, greatly improving the stability of the turning device. In practical applications, when the first or second swing arm drives the second plate group to rise, causing the first or third plate group to move, the guide components ensure that the first or third plate group moves smoothly along a predetermined trajectory. This makes the patient's turning process smoother and more comfortable, effectively reducing discomfort and potential injury caused by unstable turning movements, and further improving the reliability and safety of the nursing bed.

[0007] In one alternative embodiment, the guide assembly includes a groove and a slider disposed within the groove, wherein both the first plate group and the third plate group are connected to the slider, and the slider is adapted to move relative to the groove along the guide direction.

[0008] Beneficial effects: The sliding groove and sliding component have a simple and reliable structure, are easy to manufacture and install, reduce production costs and maintenance difficulty, and at the same time provide a stable guiding effect to ensure that the first and third plate groups always maintain the correct trajectory during movement without deviation or shaking, further enhancing the stability and reliability of the turning device.

[0009] In one optional embodiment, the guide assembly includes a guide structure having a U-shaped groove, which is the slide groove, and the slider is slidably disposed within the U-shaped groove.

[0010] Beneficial effects: The guide structure makes the sliding of the slider in the U-shaped groove smoother and less prone to jamming. At the same time, the upper and lower sidewalls of the U-shaped groove can limit the slider to a certain extent, preventing the slider from falling out of the groove during sliding, further enhancing the guiding stability of the guide assembly.

[0011] In one alternative embodiment, the guide structure is inclined, with the side of the guide structure facing the third plate group being higher than the other side.

[0012] Beneficial effects: The inclined guide structure allows the sliding parts to better adapt to the movement trajectory of the bed board when the first or third board group moves during the turning process, further reducing the possibility of jamming and shaking.

[0013] In one alternative implementation, the slider may be a slider or a pulley.

[0014] Beneficial effects: When the slider is a block, the contact surface between the block and the U-shaped groove is flat, which can provide relatively stable support and guidance. During the movement of the first or third plate group, the block slides smoothly along the U-shaped groove, ensuring the accuracy of the bed board's movement trajectory. When the slider is a pulley, the contact between the pulley and the U-shaped groove is rolling friction, which has less friction, making the movement of the first or third plate group smoother, reducing energy loss, and also effectively reducing the noise generated during the movement.

[0015] In one alternative embodiment, the guide assembly further includes a connector, wherein the first plate group or the third plate group is respectively connected to one end of the connector, and the other end of the connector is connected to the slider.

[0016] Beneficial effects: The connectors serve to transmit motion and force, and can also withstand a certain amount of force, ensuring that they will not break or deform during movement, thus guaranteeing the stability and reliability of the turning device.

[0017] In one alternative embodiment, the slider is a pulley, which is rotatably disposed at the other end of the connector.

[0018] Beneficial effects: When the pulleys roll within the U-shaped groove, they can more flexibly adapt to changes in the movement of the bed board. Whether rising or falling, the pulleys can maintain smooth rolling, thereby further reducing friction and resistance and improving the overall operating efficiency of the turning device. At the same time, the rolling characteristics of the pulleys also make the entire device generate less noise during operation, providing patients with a quieter and more comfortable nursing environment.

[0019] In one optional embodiment, the other end of the connector is provided with a connecting shaft, and the pulley is sleeved on the connecting shaft and rotatably connected to the connector.

[0020] Beneficial effects: The connecting shaft has a simple structure and is easy to install. It can ensure that the pulley rolls stably in the U-shaped groove. At the same time, the connecting shaft can also withstand the radial and axial forces generated by the pulley during rolling, preventing the pulley from shifting or falling off, and further enhancing the reliability and stability of the guide assembly.

[0021] In one optional embodiment, the connector consists of a horizontal part and a vertical part, the horizontal part being fixedly connected to the bottom of the first plate group or the third plate group, and the vertical part being rotatably connected to the pulley.

[0022] Beneficial effects: The connecting component, consisting of a horizontal and a vertical section, effectively transmits the movement of the first or third plate group to the pulley. The horizontal section is securely connected to the bottom of the plate group, ensuring accurate force transmission at the start of the plate group's movement. The connecting shaft is located on the horizontal section and fixed, further guaranteeing the stability of the pulley's rotation. This allows the entire guide assembly to function continuously and reliably during the operation of the turning device, effectively improving the overall performance and service life of the turning device.

[0023] Secondly, this utility model also provides a nursing bed, including the turning device described in any of the above embodiments.

[0024] Beneficial effects: Since the nursing bed includes a turning device, which has the same effect as a turning device, it will not be described in detail here. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, 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.

[0029] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, a turning device is provided, comprising: a bed board 1, a drive assembly, and a guide assembly 4. The bed board 1 has a first plate group 11, a second plate group 12, and a third plate group 13. The first plate group 11 and the third plate group 13 are respectively disposed on both sides of the second plate group 12, and the second plate group 12 is hinged to both the first plate group 11 and the third plate group 13. The drive assembly includes a first swing arm 2 and a second swing arm 3. One end of the first swing arm 2 is hinged to one side of the second plate group 12, and the other end of the first swing arm 2 is rotatably disposed below the bed board 1. One end of the second swing arm 3 is hinged to the other side of the second plate group 12, and the other end of the second swing arm 3 is rotatably disposed below the bed board 1. The guide assembly 4 is respectively disposed at the bottom of the first plate group 11 and the third plate group 13, and is connected to both the first plate group 11 and the third plate group 13 to provide guidance when either the first plate group 11 or the third plate group 13 moves.

[0031] Specifically, the bed board 1 has a first board assembly 11, a second board assembly 12, and a third board assembly 13. The second board assembly 12 is hinged to both the first board assembly 11 and the third board assembly 13. One end of the first swing arm 2 is hinged to one side of the second board assembly 12. When the first swing arm 2 is driven to rotate, it applies a driving force to one side of the second board assembly 12, causing one side of the second board assembly 12 to rise. Simultaneously, the rising of the second board assembly 12 also causes the side of the first board assembly 11 hinged to the second board assembly 12 to rise. The first swing arm 2 drives the second board assembly 12 to rotate. When the plate assembly 12 rises, it causes the patient to turn towards the third plate assembly 13. One end of the second swing arm 3 is hinged to the other side of the second plate assembly 12. When the second swing arm 3 is driven to rotate, it applies a driving force to the other side of the second plate assembly 12, causing the other side of the second plate assembly 12 to rise. As the second plate assembly 12 rises, it also causes the side of the third plate assembly 13 that is hinged to the second plate assembly 12 to rise. When the second swing arm 3 drives the second plate assembly 12 to rise, it causes the patient to turn towards the first plate assembly 11. The guide assembly 4 is located at the bottom of the first plate assembly 11 and the third plate assembly 13. When the side of the first plate assembly 11 or the third plate assembly 13 that is hinged to the second plate assembly 12 rises, the other side of the first plate assembly 11 or the third plate assembly 13 will move relative to it along the guide direction of the guide assembly 4.

[0032] Preferably, the bottom of the first plate group 11 and the third plate group 13 are provided with two guide components 4, which are spaced apart.

[0033] It should be noted that the first swing arm 2 and the second swing arm 3 can be driven to rotate by a rotary motor.

[0034] The precise guidance of the guide component 4 effectively prevents lateral shifts, vertical swaying, or localized jamming of the first and third plate groups 11 during movement, greatly improving the stability of the turning device. In practical applications, when the first swing arm 2 or the second swing arm 3 drives the second plate group 12 to rise, causing the first or third plate group 13 to move, the guide component 4 ensures that the first or third plate group 11 moves smoothly along a predetermined trajectory, making the patient's turning process smoother and more comfortable. This effectively reduces discomfort and potential harm to patients caused by unstable turning movements, further improving the reliability and safety of the nursing bed.

[0035] In one embodiment, the guide assembly 4 includes a groove 41 and a slider 42 disposed in the groove 41. The first plate group 11 and the third plate group 13 are both connected to the slider 42, and the slider 42 is adapted to move relative to the guide direction of the groove 41.

[0036] Specifically, such as Figure 2 As shown, a slide groove 41 is disposed at the bottom of the first plate group 11 and the third plate group 13. A sliding member 42 is slidably disposed in the slide groove 41. The side of the first plate group 11 and the third plate group 13 away from the second plate group 12 is connected to the sliding member 42. Thus, when the side of the first plate group 11 or the third plate group 13 that is hinged to the second plate group 12 is raised, the first plate group 11 or the third plate group 13 can move relative to each other along the guide direction of the slide groove 41 through the sliding member 42. Or when the first plate group 11 or the third plate group 13 is reset, it can also move relative to each other along the guide direction of the slide groove 41.

[0037] The sliding groove 41 and the sliding component 42 have a simple and reliable structure, are easy to manufacture and install, reduce production costs and maintenance difficulty, and at the same time, can provide a stable guiding effect to ensure that the first plate group 11 and the third plate group 13 always maintain the correct trajectory during the movement without deviation or shaking, further enhancing the stability and reliability of the turning device.

[0038] In one embodiment, the guide component 4 includes a guide structure 43, which has a U-shaped groove, also known as a sliding groove 41, and a slider 42 is slidably disposed within the U-shaped groove.

[0039] Specifically, such as Figure 2 As shown, the opening direction of the U-shaped groove of the guide structure 43 is towards another guide structure 43 located in the same plate group. The U-shaped groove is the slide groove 41, and the sliding member 42 is slidably disposed in the U-shaped groove.

[0040] The guide structure 43 makes the sliding member 42 slide more smoothly in the U-shaped groove and is less prone to jamming. At the same time, the upper and lower side walls of the U-shaped groove can limit the sliding member 42 to a certain extent, preventing the sliding member 42 from falling out of the groove 41 during the sliding process, and further enhancing the guiding stability of the guide assembly 4.

[0041] In one embodiment, the guide structure 43 is inclined, and the height of the side of the guide structure 43 facing the second plate group 12 is higher than that of the other side.

[0042] Specifically, such as Figure 2 As shown, the guide structure 43 is inclined, with the side facing the second plate group 12 being higher than the other side. The inclined guide structure 43 allows the sliding member 42 to better adapt to the movement trajectory of the bed board 1 when the first plate group 11 or the third plate group 13 moves during the turning process, further reducing the possibility of jamming and shaking.

[0043] In one embodiment, the slider 42 may be a slider or a pulley.

[0044] Specifically, when the slider 42 is a slider, the contact surface between the slider and the U-shaped groove is a plane, which can provide relatively stable support and guidance. During the movement of the first plate group 11 or the third plate group 13, the slider slides smoothly along the U-shaped groove to ensure the accuracy of the movement trajectory of the bed board 1. When the slider 42 is a pulley, the contact between the pulley and the U-shaped groove is rolling friction, which has a small friction force, making the movement of the first plate group 11 or the third plate group 13 smoother, reducing energy loss, and also effectively reducing the noise generated during the movement.

[0045] In one embodiment, the guide assembly 4 further includes a connector 44, with the first plate group 11 or the third plate group 13 respectively connected to one end of the connector 44, and the other end of the connector 44 connected to the slider 42.

[0046] Specifically, such as Figure 2 As shown, the connector 44 serves as the connection structure between the first plate group 11 or the third plate group 13 and the slider 42. When the first plate group 11 or the third plate group 13 moves under the action of the drive assembly, the connector 44 transmits this movement to the slider 42, causing the slider 42 to slide within the slide groove 41 along a predetermined trajectory. The design of the connector 44 can be flexibly adjusted according to actual needs, such as changing its length, shape, or material, to adapt to different specifications and requirements of the turning device.

[0047] The connector 44 plays a role in transmitting motion and force, and can also withstand a certain force to ensure that it will not break or deform during the movement, thereby ensuring the stability and reliability of the turning device.

[0048] In one embodiment, the slider 42 is a pulley, which is rotatably disposed at the other end of the connector 44.

[0049] Specifically, such as Figure 3 As shown, when a pulley is used as the sliding element 42, the pulley is rotatably mounted on the other end of the connecting element 44 via a bearing or similar structure. The pulley can be made of wear-resistant and corrosion-resistant materials to ensure its stability and durability during long-term use.

[0050] When the pulley rolls within the U-shaped groove, it can more flexibly adapt to the movement changes of the bed board 1. Whether rising or falling, the pulley can maintain smooth rolling, thereby further reducing friction and resistance and improving the overall operating efficiency of the turning device. At the same time, the rolling characteristics of the pulley also make the noise generated by the entire device lower during operation, providing patients with a quieter and more comfortable nursing environment.

[0051] In one embodiment, the other end of the connector 44 is provided with a connecting shaft 5, and a pulley is sleeved on the connecting shaft 5 and rotatably connected to the connector 44.

[0052] Specifically, such as Figure 2 As shown, the connecting shaft 5 is fixedly installed at the other end of the connecting piece 44, and its axial direction is perpendicular to the guiding direction of the slide groove 41. A through hole adapted to the connecting shaft 5 is provided at the center of the pulley. The pulley is sleeved on the connecting shaft 5 through this through hole and can rotate freely around the connecting shaft 5. The connecting shaft 5 can be made of high-strength, wear-resistant metal materials, such as stainless steel, to improve its service life and load-bearing capacity.

[0053] The connecting shaft 5 has a simple connection structure and is easy to install. It can ensure that the pulley rolls stably in the U-shaped groove. At the same time, the connecting shaft 5 can also withstand the radial and axial forces generated by the pulley during the rolling process, preventing the pulley from shifting or falling off, and further enhancing the reliability and stability of the guide assembly 4.

[0054] In one embodiment, the connector 44 consists of a horizontal part 441 and a vertical part 442. The horizontal part 441 is fixedly connected to the bottom of the first plate group 11 or the third plate group 13, and the vertical part 442 is rotatably connected to the pulley.

[0055] Specifically, such as Figure 3 As shown, one side of the horizontal portion 441 is fixedly connected to the upper side of the vertical portion 442, and the horizontal portion 441 and the vertical portion 442 form an L-shaped structure. Preferably, the horizontal portion 441 and the vertical portion 442 are integrally formed. The upper end face of the horizontal portion 441 is fixedly connected to the bottom of the first plate group 11 or the third plate group 13. The fixing method can be fasteners such as bolts, or welding. One end of the connecting shaft 5 passes through the horizontal portion 441 and is fixedly connected to the horizontal portion 441.

[0056] The connector 44, composed of the horizontal part 441 and the vertical part 442, can efficiently transmit the movement of the first plate group 11 or the third plate group 13 to the pulley. The horizontal part 441 is firmly connected to the bottom of the plate group, ensuring accurate force transmission at the beginning of the plate group's movement. The one-piece molding design enhances the overall strength of the connector 44 and reduces the risk of failure due to loose connections. The connecting shaft 5 passes through and is fixed to the horizontal part 441, further ensuring the stability of the pulley's rotation. This allows the entire guide assembly 4 to function continuously and reliably during the operation of the turning device, effectively improving the overall performance and service life of the turning device.
