Description

Technical Field

[0001] The present application relates to the technical field of flipping devices, and in particular to a flipping device. Background Art

[0002] As the elderly age, their immunity declines and they suffer from physical pain. Long-term bed rest is becoming increasingly common. Long periods of bed rest can cause back discomfort and ulcers. Turning the elderly every two hours not only helps them move their limbs but also minimizes the occurrence of bedsores. However, prolonged bed rest can weaken the elderly's limbs, making basic tasks like turning over impossible. This requires assistance from a caregiver using a turning aid. This device is placed on the elderly person, who then needs to be directly turned by the caregiver.

[0003] The traditional solution is to integrate a turning device into the turning nursing bed. While this approach can achieve basic turning functions, it has significant limitations. In multi-bed settings, such as nursing wards, each bed must be individually installed with a turning device. This not only significantly increases equipment procurement costs but also makes subsequent maintenance cumbersome. Because each turning device requires individual positioning, calibration, and maintenance, medical staff spend a significant amount of time on equipment maintenance, seriously affecting nursing efficiency.

[0004] To address these issues, related technologies have attempted to independently install the tilt drive assembly, adapting it to multiple beds. While this improvement reduces equipment procurement costs and maintenance workload, it also introduces new technical challenges. Because the independently installed tilt drive assembly lacks an effective locking mechanism, it cannot achieve stable locking when the drive is stopped, making it prone to accidental rotation. This instability not only affects the accuracy of the turning operation but also poses a serious safety hazard, potentially causing secondary injury to the patient.

[0005] In response to the above problems, relevant technologies need to be improved urgently. Summary of the Invention

[0054] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

For example, the steps described in this application can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of this application can be achieved. This is not limited herein.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0057] In the prior art, bedridden patients require turning devices to assist with position adjustment to prevent bedsores. Traditional solutions integrate turning devices into the nursing bed, resulting in high equipment costs and low maintenance efficiency in multi-bed facilities. While the independently installed turning drive assembly can accommodate multiple beds, it lacks an effective locking mechanism when the drive is stopped, posing a risk of accidental rotation and potentially causing secondary injury to the patient.

[0058] To address this issue, researchers discovered that existing independent flipping assemblies were unable to maintain stability when power was interrupted, necessitating the construction of a dual drive and locking mechanism. By analyzing the dynamic characteristics of mechanical transmission systems, they realized that relying solely on the drive assembly's braking mechanism would not completely eliminate inertial motion. Consequently, they proposed installing an independent locking device at the end of the motion execution, achieving rigid locking through physical engagement. Furthermore, they optimized the coordinated control logic of the drive and locking assemblies to ensure that the two mechanisms did not interfere with each other during motion.

[0059] Therefore, please combine Figure 1 and Figure 2 , Figure 1 This is a structural diagram of the flip device. Figure 2 It is a structural diagram of the flipping mechanism and the locking assembly. The present application proposes a flipping device including a transfer mechanism 11, a flipping mechanism 12 and a locking assembly 13. The flipping mechanism 12 includes a curved track 121, an actuator 122 and a driving assembly 123. The transfer mechanism 11 is connected to the curved track 121 and drives the curved track 121 to move. The actuator 122 is movably connected to the curved track 121. The driving assembly 123 is connected to the locking assembly 13 and engages with the curved track 121 to drive the actuator 122 to rotate around the central axis of the curved track 121. The locking assembly 13 is connected to the actuator 122 and engages with the curved track 121. The locking assembly 13 is used to lock the actuator 122, and the actuator 122 is used to perform a flipping action.

[0060] In the above-mentioned flipping device, the transfer mechanism 11 drives the flipping mechanism 12 to move to the operating area (for example, near the target bed position). The drive component 123 drives the actuator 122 to rotate smoothly along the trajectory of the curved track 121 by engaging with the curved track 121, thereby adjusting the patient's position. When the drive signal terminates, the locking component 13 immediately engages with the teeth and grooves of the curved track 121 to form a mechanical locking state. In this way, through the cooperation between the transfer mechanism 11 and the flipping mechanism 12, the drive component 123 is used to drive the actuator 122 to rotate around the curved track 121, and combined with the locking component 13 to achieve stable locking, which solves the problems of high cost of multi-bed configuration and unstable locking of independent flipping components, and has the advantages of reducing equipment costs, improving maintenance efficiency and ensuring operational safety.

[0061] It is understandable that in order to better illustrate the technical principles, the medical care field is used as a specific application scenario in this application; however, the flipping device in this application is not limited to the medical care field, but can also be used in the mechanical processing field, or other technical fields with flipping application scenarios.

[0062] In some embodiments, please combine Figure 2, the driving component 123 and the locking component 13 are alternately engaged with the arc track 121; when the flipping action is performed, the driving component 123 is engaged with the arc track 121, and the locking component 13 is separated from the arc track 121 to drive the actuator 122 to rotate around the central axis of the arc track 121; when the locking action is performed, the driving component 123 is separated from the arc track 121, and the locking component 13 is engaged with the arc track 121 to lock the actuator 122.

[0063] In this way, the safe switching between the flipping action and the locking state is achieved through the alternating engagement control of the drive component 123 and the locking component 13. The engagement design of the drive component 123 and the arc track 121 ensures that the power is effectively transmitted to the actuator 122 during the flipping process, while the engagement and separation of the locking component 13 avoids interference in power transmission. When locking is required, the disengagement of the drive component 123 can eliminate the influence of residual power, and the engagement of the locking component 13 with the arc track 121 forms a rigid constraint to prevent the actuator 122 from rotating freely. The alternating engagement mechanism of the drive component 123 and the locking component 13 not only ensures the effectiveness of the driving of the flipping action, but also realizes the self-locking of the actuator 122 through mechanical locking, fundamentally solving the defect of the independent drive component 123 lacking stable locking. Among them, the design of the drive component 123 engaging only in the working state reduces the wear of the transmission system, and the structure of the locking component 13 engaging in the non-driving state improves safety redundancy through physical limiting.

[0064] For ease of explanation, Figure 1 A three-dimensional rectangular coordinate system is added, where the direction of the X-axis is the first direction, i.e., the setting direction of the first guide rail 1211 and the second guide rail 1212; the direction of the Y-axis is the second direction, i.e., the setting direction of the two sets of lifting components 111; and the direction of the Z-axis is the third direction, i.e., the direction in which the lifting component 111 drives the beam 112 to rise and fall, i.e., the direction of gravity; wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0065] In some embodiments, please combine Figure 1 The flipping device includes a transfer mechanism 11 and a flipping mechanism 12. The flipping mechanism 12 includes an arc track 121, an actuator 122, a driving component 123 and a locking component 13. Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the first track. Figure 4This is a structural schematic diagram of the second track. The arc track 121 includes a first guide rail 1211 and a second guide rail 1212. A first arc groove 1214 is provided on the inner side of the first guide rail 1211. The second guide rail 1212 and the first guide rail 1211 are spaced apart along the first direction, and a second arc groove 1215 is provided on the inner side of the second guide rail 1212. The central axes of the first arc groove 1214 and the second arc groove 1215 are coaxial. The actuator 122 is rollably connected to the first guide rail 1211 at one end in the first direction through the first arc groove 1214, and is rollably connected to the second guide rail 1212 at the other end in the first direction through the second arc groove 1215.

[0066] In this way, when the driving component 123 drives the actuator 122 to move along the arc track 121, the two ends of the actuator 122 in the first direction can be rolled into the first arc groove 1214 and the second arc groove 1215 respectively to form rolling friction, which not only reduces the driving energy consumption but also avoids the vibration caused by sliding friction; the first guide rail 1211 and the second guide rail 1212 are arranged at intervals to form a symmetrical support frame, so that the actuator 122 is always in a bilaterally constrained state during the flipping process, so as to improve the stability of the actuator 122 during movement; moreover, the synergistic action of the first guide rail 1211 and the second guide rail 1212 evenly distributes the flipping torque to the support frames on both sides, effectively suppressing the deformation of the arc track 121 caused by unilateral force, thereby extending the service life of the flipping device.

[0067] Specifically, the first guide rail 1211 refers to an arc-shaped support member with a preset curvature radius, and the semicircular groove opened on the inner side forms a first arc-shaped groove 1214; the second guide rail 1212 refers to an arc-shaped support member with a preset curvature radius, and the semicircular groove opened on the inner side forms a second arc-shaped groove 1215.

[0068] In some embodiments, combined Figure 5 , Figure 5 The diagram below shows the structure of the actuator, drive assembly, and locking assembly. The actuator 122 includes an actuator body 1221, a first roller 1222, and a second roller 1223. The actuator body 1221 is disposed between the first guide rail 1211 and the second guide rail 1212. The first roller 1222 is rotatably connected to one end of the actuator body 1221 in the first direction and rollably abuts against the top wall of the second arcuate slot 1215. The second roller 1223 is rotatably connected to one end of the actuator body 1221 in the first direction and rollably abuts against the bottom wall of the second arcuate slot 1215.

[0069] In this way, the actuator 1221 straddles the two parallel first conductors and second guide rails 1212, forming a stable spatial support structure. As the actuator 122 moves along the curved track 121, the first roller 1222 maintains rolling contact with the top wall of the second curved groove 1215, while the second roller 1223 maintains rolling contact with the bottom wall. This symmetrical dual-roller arrangement constrains the actuator 122 radially along the curved track 121 during movement, preventing radial oscillation of the actuator 122 during operation and improving its stability. Furthermore, the rolling contact of the rollers converts sliding friction into rolling friction, reducing resistance to movement.

[0070] Specifically, the first roller 1222 and the second roller 1223 are both rotatably connected to the execution body 1221 through a roller bracket.

[0071] In some optional embodiments, during the flipping operation, the executing body 1221 can be a flipping board, and the patient can lie directly on the flipping board. The flipping board supports the patient's hips, back and neck area, and the patient can achieve the flipping action under the push of the flipping board.

[0072] In other optional embodiments, the execution body 1221 can also be a connector, and is detachably connected to the wearable device worn by the patient to achieve the turning action. The wearable device worn by the patient is a prior art. Before turning over, the medical staff first wears the wearable device on the patient's body, and uses the wearable device to support the patient's hips, back and neck, and then connects it to the connector. When the turning device is started, it can drive the patient to turn over.

[0073] It should be noted that the structure of the execution entity 1221 disclosed above is only an example, and this application does not limit the specific structure of the execution entity 1221.

[0074] In some embodiments, combined Figure 2 and Figure 3 The arcuate track 121 further includes an arcuate rack 1213, to which the top wall of the first arcuate groove 1214 is connected. The drive assembly 123 includes a driver 1231 and a gear 1232. The driver 1231 is fixedly connected to the locking assembly 13. The gear 1232 is connected to the output end of the driver 1231 and meshes with the arcuate rack 1213. For example, the driver 1231 may be a motor.

[0075] In this way, when the driving member 1231 drives the gear 1232 to rotate through the output shaft, the meshing action of the gear 1232 and the arc-shaped rack 1213 converts the rotational motion into a curved displacement along the arc-shaped track 121, thereby driving the actuator 122 to rotate around the central axis of the arc-shaped track 121. The fixed connection between the driving member 1231 and the locking assembly 13 allows the driving mechanism and the locking mechanism to form a physical integration. During the driving process, the gear 1232 and the arc-shaped rack 1213 always maintain rigid contact, ensuring stable output of the transmission torque. The design of the arc-shaped rack 1213 set on the top wall of the first arc groove 1214 enables the gear 1232 to only bear the driving torque, and the gravity load of the actuator 122 is shared by the first roller 1222 and the second roller 1223, avoiding abnormal wear on the tooth surface of the gear 1232 due to the vertical load.

[0076] Furthermore, the arc-shaped rack 1213 can be disposed inside the first arc-shaped groove 1214 , or can be disposed outside the first arc-shaped groove 1214 .

[0077] Preferably, the arc track 121 , the first arc groove 1214 and the second arc groove 1215 have the same shape, and their central axes are collinear.

[0078] In an optional embodiment, the arc-shaped rack 1213 and the first guide rail 1211 are an integrated structure, so as to improve the firmness between the arc-shaped rack 1213 and the first guide rail 1211, thereby increasing the service life of the arc-shaped rail 121.

[0079] In another optional embodiment, the arc-shaped rack 1213 and the first guide rail 1211 are split structures, wherein the arc-shaped rack 1213 and the first guide rail 1211 can be fixed by welding or screws.

[0080] Preferably, the arc-shaped rack 1213 can be realized by using a segmented arc-shaped steel rack, and the segmented structure is easy to process.

[0081] In some embodiments, combined Figure 5 The actuator 122 further includes a third roller 1224 . The third roller 1224 is disposed at the other end of the actuator body 1221 in the first direction and can be rolled against the bottom wall of the first arc-shaped groove 1214 .

[0082] In this way, the rolling contact between the third roller 1224 and the bottom wall of the first arc-shaped groove 1214 enables the executive body 1221 to contact the top wall and the bottom wall respectively at the second arc-shaped groove 1215 through the first roller 1222 and the second roller 1223, while forming a third contact point at the bottom wall of the first arc-shaped groove 1214, and the gear 1232 forms a fourth contact point with the top wall of the first arc-shaped groove 1214. These four contact points constitute a stable support structure, which is conducive to the stable movement of the executive member 122.

[0083] Preferably, there are two third rollers 1224 , and the two third rollers 1224 are spaced apart from each other, so as to further improve the support stability of the actuator 122 .

[0084] Furthermore, the actuator 122 further includes a fourth roller and a fifth roller. The fourth roller is rotatably connected to one end of the actuator body 1221 in the first direction and can roll against the side wall of the first arcuate groove 1214. The fifth roller is rotatably connected to the other end of the actuator body 1221 in the first direction and can roll against the side wall of the second arcuate groove 1215.

[0085] In this way, the fourth roller and the fifth roller can be used to limit the second direction to prevent the actuator 122 from shaking in the second direction, thereby further improving the stability of the actuator 122 during movement.

[0086] In some optional embodiments, the first arc-shaped groove 1214 and the second arc-shaped groove 1215 are both of the same semicircular structure.

[0087] In some other optional embodiments, the first arc-shaped groove 1214 and the second arc-shaped groove 1215 are both of the same semi-elliptical structure.

[0088] In this way, the semicircular arc structure and the semi-elliptical arc structure are both regular arc structures. Compared with the irregular arc structure, the processing technology is relatively simple, which is conducive to improving the processing efficiency of the first arc groove 1214 and the second arc groove 1215; at the same time, the semicircular structure and the semi-elliptical structure can achieve flipping at any angle within 180°, so that the flipping device has a larger flipping angle and will not be interfered with by the nursing bed.

[0089] It should be noted that the structures of the first arc-shaped groove 1214 and the second arc-shaped groove 1215 disclosed above are merely examples, and the present application does not limit the specific structures of the first arc-shaped groove 1214 and the second arc-shaped groove 1215 .

[0090] In some embodiments, combined Figure 2 and Figure 5The locking assembly 13 includes a movable member 131, a locking member 132, and a power member 133. The middle portion of the movable member 131 is rotatably connected to the actuator 122. The driving assembly 123 is mounted on one end of the movable member 131 in the second direction and engages with the arcuate track 121. The locking member 132 is connected to the other end of the movable member 131 in the second direction. The locking member 132 is used to engage with the arcuate track 121 to lock the actuator 122. The power member 133 is connected to the actuator 122 and the movable member 131. The power member 133 is used to drive the movable member 131 to rotate so that the locking member 132 and the driving assembly 123 alternately engage with the arcuate track 121. The rotation axis of the movable member 131 extends along the first direction. Exemplarily, the locking member 132 can be a gear.

[0091] When the drive assembly 123 needs to drive the actuator 122 to rotate along the curved track 121, the power member 133 drives the movable member 131 to rotate about an axis extending in the first direction, causing the gear 1232 of the drive assembly 123 to engage with the curved rack 1213, while the locking member 132 disengages from the curved rack 1213. At this point, the drive assembly 123 can drive the actuator 122 to rotate freely along the curved track 121. When the actuator 122 reaches the target position and needs to be locked, the power member 133 drives the movable member 131 to move in the opposite direction. The movable member 131 rotates, causing the gear 1232 of the drive assembly 123 to disengage from the curved rack 1213, while the locking member 132 engages with the curved rack 1213, thereby achieving mechanical locking and fixation.

[0092] Thus, by designing movable member 131 as a lever-type structure, active switching between drive assembly 123 and locking member 132 is achieved, achieving mechanical interlocking at the moment of stopping. In the prior art, locking mechanisms are often attached devices independent of the drive system. However, this application integrates the driving and locking functions into the same movable member 131, controlling the switching between the two operating states through a single power source. This simplifies the structure and eliminates the time difference between the driving and locking actions in traditional devices.

[0093] In some optional embodiments, the power member 133 is an electric telescopic rod, and is obliquely arranged between the actuator 122 and the movable member 131. The electric telescopic rod is rotatably mounted on the actuator 122, and the telescopic end of the electric telescopic rod is hinged to the other end of the movable member 131 in the second direction; the power member 133 is used to drive the movable member 131 to rotate, so that the locking member 132 and the driving assembly 123 are alternately engaged with the arc track 121.

[0094] In this way, by integrating the telescopic motion of the electric telescopic rod with the articulated structure, the disengagement of the drive assembly 123 from the locking member 132 is integrated into the same power source, achieving automated and synchronized state switching. Compared to traditional manual locking methods, this design eliminates operational delays and ensures that the locking action is executed immediately when the drive stops.

[0095] It should be noted that, since the movable member 131 is a movable component, the second direction of the movable member 131 is the position state presented when the movable member 131 moves to a horizontal state.

[0096] Preferably, the number of movable parts is two.

[0097] In other optional embodiments, the power member 133 includes a permanent magnet, an electromagnet, and an elastic member. The permanent magnet is connected to one end of the movable member 131 in the second direction. The electromagnet is arranged corresponding to the permanent magnet and is connected to the actuator 122. The permanent magnet and the electromagnet are used to generate a magnetic repulsive force to cause the gear of the drive assembly 123 to engage with the arc-shaped rack 1213. One end of the elastic member is connected to the other end of the movable member 131 in the second direction, and the other end of the elastic member is connected to the actuator 122. The elastic force released by the elastic member is used to drive the movable member 131 to rotate, thereby driving the locking member 132 to engage with the arc-shaped rack 1213. Exemplarily, the elastic member can be a spring.

[0098] In this way, the magnetic repulsion force is generated between the permanent magnet and the electromagnet, so that the gear of the driving component 123 is engaged with the arc-shaped rack 1213; when the power is off, the magnetic repulsion force between the permanent magnet and the electromagnet disappears, and the elastic part can automatically push the movable part 131 to rotate, so as to drive the locking part 132 to be clamped on the arc-shaped rack 1213, and disengage the gear 1232 of the driving component 123 from the arc-shaped rack 1213, thereby realizing automatic locking when the power is off, thereby further improving the safety performance of the flipping device.

[0099] It should be noted that the structure of the power component 133 disclosed above is only an example, and this application does not limit the specific structure of the power component 133.

[0100] In some embodiments, the locking assembly 13 further includes a detector and a controller. The detector is electrically connected to the drive assembly 123 and is used to detect the current signal of the drive assembly 123. The controller is electrically connected to the detector and the power member 133. The controller is used to obtain the current signal detected by the detector and determine whether the current signal is abnormal. When the detected current signal is abnormal, the controller controls the power member 133 to drive the movable member 131 to rotate, thereby separating the drive assembly 123 from the curved track 121 and engaging the locking member 132 with the curved track 121 to lock the actuator 122.

[0101] In this way, when the drive assembly 123 is operating normally, the detector continuously collects the real-time working current of the drive member 1231 and transmits the current signal to the controller. The controller has preset upper and lower current threshold values. When the current value exceeds the upper limit, it is determined to be an overload abnormality, and when it is lower than the lower limit, it is determined to be a stall abnormality. Once an abnormal signal is identified, the controller immediately sends a pulse instruction to the power member 133. After receiving the instruction, the power member 133 drives the movable member 131 to rotate around its rotation axis by a specific angle, so that the gear 1232 of the drive assembly 123 that was originally engaged with the arc-shaped rack 1213 is disengaged, and at the same time drives the pawl of the locking member 132 to be embedded in the tooth groove of the arc-shaped rack 1213. At this time, the actuator 122 is completely fixed by the mechanical locking mechanism to avoid accidental rotation due to motor failure or sudden load change, thereby further improving the safety of the flipping device.

[0102] Furthermore, the detection body refers to a current detection device for detecting the operating status of the driving component 123, which can be implemented specifically by a current transformer or a Hall current sensor, and its function is to capture the operating current changes of the driving motor in real time.

[0103] Furthermore, the controller refers to a control unit with signal processing capabilities, which can be implemented using a PLC or an embedded microcontroller, and determines whether the device is in an abnormal operating condition through a preset current threshold range.

[0104] Furthermore, the abnormal current signal refers to a sudden change in current generated when the drive motor is overloaded, stalled or short-circuited, which is specifically manifested as the current value exceeding the preset safety range. This abnormal state is judged as an equipment operation risk, where the preset safety range is the current range when the drive component 1231 is working stably.

[0105] In some embodiments, combined Figure 1 The transfer mechanism 11 includes two sets of lifting assemblies 111, a crossbeam 112, and two sets of running wheels 113. The two sets of lifting assemblies 111 are spaced apart along the second direction, and the crossbeam 112 is disposed between the two sets of lifting assemblies 111. The ends of the crossbeam 112 are respectively connected to the top ends of the lifting assemblies 111. Each set of lifting assemblies 111 is used to drive the crossbeam 112 to move along the third direction. The arc-shaped track 121 is slidably connected to the crossbeam 112 in the second direction; each set of running wheels 113 is connected to the bottom end of the corresponding lifting assembly 111.

[0106] In this way, the two sets of lifting components 111 are arranged at intervals along the lateral direction to form a stable support structure, and the height adjustment is achieved by driving the crossbeam 112 to move in the vertical direction through synchronous lifting actions. The crossbeam 112 is connected to the curved track 121 through a lateral sliding pair, so that the flipping mechanism 12 can be positioned in a lateral translation. The running wheels 113 are installed at the bottom of the lifting component 111, so that the entire device has the ability to move in a plane. When it is necessary to adapt to different beds, the running wheels 113 move the entire device to the target position, the lifting component 111 adjusts the height of the crossbeam 112, and the crossbeam 112 drives the curved track 121 to slide laterally, forming a precise positioning in three-dimensional space. After positioning, the lifting component 111 replaces the running wheels 113 with rigid supports to bear the weight, ensuring the structural stability in the working state.

[0107] Furthermore, the lifting assembly 111 refers to an execution unit for realizing vertical displacement, which can be realized by an electric push rod or a hydraulic cylinder. The height of the beam 112 can be synchronously adjusted through two symmetrically distributed sets of lifting assemblies 111.

[0108] Furthermore, the crossbeam 112 refers to a rigid load-bearing structure connecting the two sets of lifting components 111, and can be specifically implemented by an I-beam or a box beam.

[0109] Furthermore, the arc track 121 and the crossbeam 112 are slidably connected via a sliding block.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
