Description

Technical Field

[0001] This application relates to the field of axillary transposition machine technology, and more particularly to a buttock lifting device used in axillary transposition machines. Background Technology

[0002] For people with disabilities or lower limb disabilities, the most common basic activity in daily life is moving between beds, toilets, wheelchairs, dining tables, and sofas. Without the assistance of caregivers and transfer devices, such transfers are extremely difficult. Existing technologies often use axillary support transfer devices to facilitate the movement of disabled patients in daily life. A human support device and transfer device for a transfer machine, published in CN111631881A, can be referenced. This device supports the user through the axillary support, with the user's feet resting on foot pedals. During the overall movement of the transfer machine, the user must maintain a standing posture. The weight of the body is entirely applied to the axillary support, which can cause discomfort in the armpit area. Furthermore, some patients cannot stand for long periods or are even unable to stand at all. This type of transfer machine cannot meet the actual needs of these patients.

[0003] This application proposes a hip lift device for use on an axillary support transfer machine, which is suitable for providing seating functionality for disabled patients. Summary of the Invention

[0004] In view of this, this application proposes a hip lifting device for use in an axillary support type transfer machine.

[0005] According to one aspect of this application, a hip lifting device for use in an axillary support type transfer machine is provided, comprising: a base, a seat cushion, a connecting assembly, a connecting shaft, a mounting bracket, and a drive device; The base is suitable for installation on the mobile chassis of the axillary support transfer machine, and the mounting bracket is fixedly set on the top of the base; The connecting shaft is mounted on the mounting bracket, the seat cushion is mounted on the connecting assembly, and the connecting assembly is sleeved on the connecting shaft so that the seat cushion swings around the connecting shaft as an axis when the connecting assembly rotates on the connecting shaft. The drive unit is mounted on the base and the drive end of the drive unit is connected to the seat cushion, which is suitable for driving the seat cushion to swing, thereby raising or lowering the seat cushion.

[0006] In one possible implementation, the mounting bracket includes two parallel mounting plates and connecting rods, with two or more connecting rods between the two mounting plates.

[0007] In one possible implementation, the drive unit is located between two mounting plates, and the drive end of the drive unit is hinged to the connecting assembly.

[0008] In one possible implementation, the connecting assembly includes: two connecting plates arranged parallel to each other, one end of the two connecting plates having a through hole for the connecting shaft to pass through, and a seat cushion being disposed on the side of the two connecting plates opposite to the drive device.

[0009] In one possible implementation, a first pin is provided between the two connecting plates, and the driving end of the driving device is hinged to the first pin.

[0010] In one possible implementation, the connecting assembly has a limiting plate at the top, and the limiting plate is located above the mounting bracket. The length of the limiting plate is greater than the distance between the two mounting plates, so that the limiting plate rests on top of the mounting bracket when the seat is in the retracted state.

[0011] In one possible implementation, the main body of the limiting plate is a rectangular plate-like structure.

[0012] In one possible implementation, a seat cushion plate is provided between the seat cushion and the connecting assembly.

[0013] In one possible implementation, the mounting bracket also includes a stop bar, which is vertically positioned between the two mounting plates to facilitate contact with the back of the connecting assembly.

[0014] In one possible implementation, the drive device is an electric actuator.

[0015] Effectiveness: The base is designed to mount the entire device onto the chassis of the axillary transposition machine, allowing the entire structure to move during chassis movement. The seat cushion supports the user's buttocks, providing a reclining function. The connecting component acts as a bridge between the drive unit and the seat cushion, supporting and lifting the cushion, while the drive unit provides power for its movement. When the axillary support lifts the user from their original position, the user's buttocks rest on the seat cushion. The drive end of the drive unit then extends and pushes the connecting component to rotate around its connecting shaft. This causes the seat cushion to lift upwards and extend into the horizontal plane, allowing the user to sit comfortably. The swingable seat structure allows disabled patients to maintain a seated posture during transfer, effectively reducing pressure on the axillary weight-bearing area, avoiding discomfort from prolonged standing, and ensuring patient safety and comfort during transfer. This application can be integrated into the existing chassis of axillary transposition machines, offering convenient operation and significantly improving the machine's adaptability to patients with different physical conditions.

Those skilled in the art should understand that this utility model can be implemented even without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail, in order to highlight the main points of this utility model.

[0024] Figure 1 This diagram shows the main structure of a hip lift device applied to an axillary transposition machine according to an embodiment of this application; Figure 2 This diagram shows a partial structural view of a hip lifting device applied to an axillary transposition machine according to an embodiment of this application; Figure 3 This illustration shows a partial structural diagram of a hip lift device applied to an axillary transposition machine according to an embodiment of this application; as shown. Figure 1 As shown, this buttock lifting device for use on an axillary transposition machine is suitable for installation on the mobile chassis of the axillary transposition machine. It includes: a base 100, a seat cushion 500, a connecting assembly, a connecting shaft 400, a mounting frame, and a drive device 600. The mounting frame is fixedly mounted on the top of the base 100, which is suitable for connection to the mobile chassis of the axillary transposition machine. The connecting shaft 400 is mounted on the mounting frame, and the seat cushion 500 is mounted on the connecting assembly. The connecting assembly is sleeved on the connecting shaft 400, so that when the connecting assembly rotates on the connecting shaft 400, the seat cushion 500 swings about the connecting shaft 400 as an axis. The drive device 600 is mounted on the base 100, and the drive end of the drive device 600 is connected to the seat cushion 500, suitable for driving the seat cushion 500 to swing, thereby lifting or retracting the seat cushion 500.

[0025] It should be noted here that the base 100 is suitable for mounting the entire device on the chassis of the armpit-support type transfer machine, thereby driving the overall structure of this application to move during the movement of the chassis. The seat cushion 500 is suitable for supporting the user's buttocks and providing a reclining function. The connecting component acts as a connecting bridge between the drive device 600 and the seat cushion 500, and is suitable for supporting and lifting the seat cushion 500. The drive device 600 is suitable for providing power for the movement of the seat cushion 500. The connecting component can rotate on the connecting shaft 400. When the armpit support of the armpit-support type transfer machine lifts the user from the original position, the user... The user's buttocks rest against the seat cushion 500. Then, the drive end of the drive device 600 extends and pushes the connecting component to rotate around the connecting shaft 400. The connecting component causes the seat cushion 500 to lift upward and extend into the horizontal plane, allowing the user's buttocks to sit on the seat cushion 500. When the user needs to leave the armpit-support type transfer machine, the armpit support of the armpit-support type transfer machine lifts the user off the seat cushion 500. Then, the drive end of the drive device 600 retracts and pulls the connecting component to rotate in the opposite direction around the connecting shaft 400. The connecting component causes the seat cushion 500 to retract downward to the initial position, allowing the user to leave the seat cushion 500.

[0026] In summary, this application offers the following advantages: By incorporating a swingable seat cushion 500, disabled patients can maintain a seated posture during transfer, effectively reducing pressure on the underarm weight-bearing area and avoiding discomfort from prolonged standing. It is particularly suitable for patients unable to stand independently or with weak lower limbs, allowing the buttocks to fully rest on the seat cushion 500 while the armpit supports the upper body, achieving a reasonable distribution of body weight. The drive device 600 precisely controls the rotation angle of the connecting components, ensuring smooth operation of the seat cushion 500 during lifting and retraction, guaranteeing patient safety and comfort during transfer. This device can be seamlessly integrated into the mobile chassis of existing armpit-supported transfer machines, offering convenient operation and significantly improving the adaptability of the transfer machine to patients with different physical conditions, especially suitable for daily care scenarios such as bed-chair transfers and toilet assistance. The overall structure is compact, lightweight, and has a strong load-bearing capacity, ensuring the overall device remains stable and does not wobble during transfer.

[0027] In one possible implementation, the base 100 is a grid-like rectangular frame structure formed by splicing multiple horizontal and vertical beams. This design effectively reduces the overall weight of the device, while the grid structure enhances the rigidity and deformation resistance of the base 100, ensuring stability when bearing the user's weight and preventing swaying during relocation. This grid-like rectangular frame structure facilitates the use of standardized horizontal and vertical beams during manufacturing, reducing production costs and allowing for flexible adjustments based on the specific dimensions of the mobile chassis. Furthermore, the gaps in the grid structure reduce the risk of corrosion due to material accumulation and provide space for wiring channels, thereby improving the overall durability and functionality of the equipment.

[0028] In one possible implementation, the mounting bracket includes two parallel mounting plates 200 and connecting rods 210. The two mounting plates 200 are vertically mounted on the top surface of the base 100, and two or more connecting rods 210 are provided between the two mounting plates 200. Figure 3 As shown, the main body of the mounting plate 200 is an irregularly shaped plate structure (the specific shape can be designed according to the structure of different types of armpit support transfer machines), which must ensure that the seat cushion 500 can be stably installed; multiple cylindrical connecting rods 210 are vertically arranged between the two mounting plates 200, which are suitable for stably connecting the two mounting plates 200 and ensuring that the two mounting plates 200 remain parallel to each other to securely install the two ends of the connecting shaft 400.

[0029] Furthermore, there are two connecting rods 210.

[0030] Furthermore, such as Figure 9 As shown, a preset angle a is provided between the side of the mounting plate 200 facing the seat cushion 500 and the side of the mounting plate 200 connecting the base 100, and a preset angle b is provided between the side of the mounting plate 200 facing the limiting plate 310 and the side of the mounting plate 200 facing the seat cushion 500.

[0031] Preferably, the preset angle 'a' is 77°; angle 'a' also determines the range of motion of the seat cushion 500 from 0° to 77°. The larger the angle 'a', the better, so that the connecting plate 300 can retract more, giving the user more room to move their feet during the transfer process. However, due to the limitations of the electric push rod's stroke and size, the current optimal angle 'a' of 77° is already the best.

[0032] Preferably, the preset angle b is in the range of 103°-138°.

[0033] In one possible implementation, the mounting plate 200 has multiple weight-reducing holes 230 to reduce the overall weight of the device.

[0034] In one possible implementation, the drive unit 600 is located between two mounting plates 200, and the drive end of the drive unit 600 is hinged to the connecting assembly. This arrangement ensures the central transmission of driving force, reduces the generation of lateral torque to avoid structural deformation, and achieves smooth force transfer through the hinged connection, ensuring smooth movement of the cushion 500 during lifting and retraction. This layout optimizes space configuration, allowing the drive unit 600 to be tightly integrated with the mounting frame and connecting assembly, reducing the risk of external interference, and enabling efficient operation even in confined nursing environments, ensuring the safety and comfort of patients during transfer.

[0035] In one possible implementation, such as Figure 6As shown, the connecting assembly includes two parallel connecting plates 300. One end of each connecting plate 300 has a through hole 330 for a connecting shaft 400 to pass through. A seat cushion 500 is disposed on the side of the two connecting plates 300 facing away from the drive device 600. Furthermore, the main body of each connecting plate 300 is a long, narrow plate structure. One end of each connecting plate 300 has a circular through hole 330 for the connecting shaft 400 to pass through, and the middle of each connecting plate 300 has a circular through hole for a first pin 340 to pass through. The sides of both connecting plates 300 facing away from the drive device 600 are fixedly connected to the seat cushion 500.

[0036] Furthermore, three connecting plates 320 are provided between the two connecting plates 300. The planes of the three connecting plates 320 are perpendicular to the planes of the connecting plates 300. The three connecting plates 320 are suitable for connecting the two connecting plates 300 into one unit by welding, thereby improving the overall structural strength of the connecting assembly. A trigger plate 820 is installed on the uppermost connecting plate 320.

[0037] In one possible implementation, a first pin 340 is provided between the two connecting plates 300, and the driving end of the driving device 600 is hinged to the first pin 340. For example... Figure 5 As shown, the first pin 340 passes through the through holes of the two connecting plates 300, and the other end of the first pin 340 is vertically inserted with a rod to limit the position of the first pin 340 and prevent the first pin 340 from disengaging from the connecting plate 300. The drive rod of the drive device 600 is sleeved on the first pin 340.

[0038] In one possible implementation, such as Figure 6 As shown, the connecting assembly also includes two or more support members 350. The two or more support members 350 are respectively disposed on the opposite sides of the two connecting plates 300 and arranged sequentially along the length of the connecting plates 300. The main body of the support member 350 is a trapezoidal plate structure. The plane of the support member 350 is perpendicular to the plane of the connecting plate 300, and its long side faces the seat cushion 500 to support the seat cushion 500, thereby dispersing the pressure applied by the seat cushion 500 to the connecting plate 300.

[0039] In one possible implementation, such as Figure 4 As shown, a limiting plate 310 is provided at the top of the connecting assembly, and the limiting plate 310 is located above the mounting frame. The length of the limiting plate 310 is greater than the distance between the two mounting plates 200, so that the limiting plate 310 rests on the top of the mounting frame when the cushion 500 is in the retracted state. It should be noted that when the cushion 500 is retracted to the initial position, the contact design between the limiting plate 310 and the mounting frame can effectively prevent excessive swinging. Furthermore, the limiting plate 310 is fixed to the two connecting plates 300 by welding.

[0040] Furthermore, the main body of the limiting plate 310 has a rectangular plate-like structure.

[0041] In one possible implementation, the connecting shaft 400 includes a main shaft and an outer cylinder 410. The two ends of the main shaft pass through through holes in two mounting plates 200 and through holes 330 in two connecting plates 300. The outer cylinder 410 is sleeved on the outside of the main shaft. Limiting rings 430 are fixedly provided at both ends of the main shaft, and the two limiting rings 430 respectively contact the end faces of the outer cylinder 410 to limit its position. Bushings 420 are provided between the two mounting plates 200 and the main shaft, and the bushings 420 sleeve the main shaft. Two threaded caps 440 are threadedly connected to both ends of the main shaft to limit its movement and prevent it from detaching from the mounting bracket. It should be noted that the outer cylinder 410 is fixed to the connecting plates 300 by welding, and the connecting shaft 400 can rotate with the connecting assembly when it rotates.

[0042] In one possible implementation, such as Figure 4 As shown, a seat cushion plate 510 is provided between the seat cushion 500 and the connecting assembly. The main body of the seat cushion plate 510 is adapted to the main body of the seat cushion 500 and has an isosceles trapezoidal plate structure. Bolt holes 511 for connecting the seat cushion 500 are provided at the four corners. The side of the seat cushion plate 510 facing away from the seat cushion 500 is fixedly connected to the connecting assembly by welding. The seat cushion plate 510 and the seat cushion 500 are fixedly connected by bolts.

[0043] Preferably, the seat cushion is filled with high-density self-rebound polyurethane foam sponge, and the surface is wrapped and shaped with artificial leather.

[0044] In one possible implementation, the mounting bracket further includes two stops 220, both vertically positioned between the two mounting plates 200. This allows both stops 220 to contact the back of the connecting assembly when the seat cushion 500 is in the retracted state. The stops 220 limit the backward tilt of the connecting assembly, providing double protection for the stability of the device in its reset state.

[0045] In one possible implementation, it also includes: a first limit switch 700, such as... Figure 3 As shown, the first limit switch 700 is mounted on the top surface of the bottom stop bar 220 via the riser bracket 710, and the trigger end of the first limit switch 700 faces the side where the seat cushion 510 is located. When the seat cushion 510 is retracted into place, the first limit switch 700 is triggered, the first limit switch 700 is turned on, and a signal is sent to the main control board. The main control board controls the drive device 600 to stop driving immediately.

[0046] In one possible implementation, a second limit switch 800 is also included, such as... Figure 2As shown, the second limit switch 800 is mounted on the side wall of the top stop bar 220 via a fixing plate 810, and the trigger end of the second limit switch 800 faces upward. When the seat cushion 510 is unfolded into place, the trigger plate 820 triggers the second limit switch 800, the second limit switch 800 is turned on, and a signal is sent to the main control board. The main control board then controls the drive device 600 to stop immediately.

[0047] like Figure 1 As shown, the trigger plate 820 protrudes from the top of the connecting assembly and can rotate with the connecting assembly. Furthermore, the main body of the trigger plate 820 has a U-shaped plate structure, and one end of the trigger plate 820 is fixedly connected to the connecting assembly by bolts.

[0048] In one possible implementation, a pad 830 is provided on the top surface of the stop lever 220 on which the second limit switch 800 is installed to protect the stop lever 200 and prevent the connecting components from impacting the stop lever 220.

[0049] In one possible implementation, the base 100 is provided with a hinge seat 610, on which a second pin 611 is provided, and the housing of the drive device 600 is hinged to the hinge seat 610. Figure 4 As shown, the main body of the hinge seat 610 has a Π-shaped structure, with the closed end welded to the base 100 and the open end provided with a second pin 611.

[0050] Furthermore, the drive unit 600 uses an electric actuator with model number DHLA8000-A1-300MM, with a thrust of 8000N and a stroke of 300mm.
