Description

Technical Field

[0001] The utility model relates to the technical field of patient transfer devices, and particularly relates to a foldable transfer machine. Background Art

[0002] A transfer machine is a tool for transferring patients. It can lift a patient from a seat, and a caregiver can push the patient to the toilet and gently place the patient on the toilet seat. It can also be used in scenarios such as transferring a patient from a seat to a dining chair where patient transfer is required. Such a device is usually driven by an electric push rod to drive a robotic arm, and the robotic arm lifts or lowers the patient.

[0003] At present, the transfer machines on the market generally mainly consist of a frame, a clamping mechanism or a forklift mechanism that can be lifted or lowered relative to the frame and is provided on the frame, and walking wheels provided at the bottom of the frame. On the one hand, during the transportation process of such transfer machines, due to the too large packaging volume, the logistics costs of dealers are relatively high, and the large volume directly leads to an increase in the warehousing costs of dealers, and it is not easy to carry the machine after-sales. On the other hand, most of such transfer machines are welded by steel pipes, and the structural form is relatively monotonous, only meeting the basic function of lifting and lowering patients, and there is no transfer machine that takes into account both function and aesthetics. For example, Chinese Patent Publication No. CN114452115A discloses an axillary support type transfer machine, including a frame, a pedal assembly, a foot stabilizing assembly, a forklift assembly and a driving assembly. The forklift assembly is hinged to the frame, and the output end of the driving assembly is hinged to the forklift assembly. The forklift assembly includes a connecting frame, a first support arm, a second support arm, a first armrest and a second armrest. The first support arm and the second support arm are respectively fixed to the connecting frame. The connecting frame is hinged to the frame, and the output end of the driving assembly is hinged to the connecting frame. The connecting frame includes a mounting plate, a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to the mounting plate and the other end is hinged to the frame. One end of the second connecting rod is hinged to the mounting plate and the other end is hinged to the first connecting rod. The driving assembly is hinged to the middle of the second connecting rod. The transfer machine of the above technical solution slowly lifts the upper limb of the patient from a sitting position through the forklift assembly, and after moving to the required position, the forklift assembly moves down to slowly lower the patient to complete the transfer operation. The patient does not need to exert force throughout the process and is not likely to cause secondary injury to the patient. However, the transfer machine of the above technical solution has multiple hinged positions. For example, both the upper and lower ends of the first connecting rod and the second connecting rod are respectively hinged to the mounting plate and the frame, and the output end of the driving assembly is hinged to the second connecting rod. Since a large gap needs to be reserved at the hinged position to ensure that the forklift assembly can rotate freely during the lifting and lowering process, and the hinged positions of the above technical solution are directly exposed, there is a risk of clamping the clothes or fingers of the caregiver during use, and it is also possible to enter foreign objects, resulting in inconvenient use and the need to clean at all times, which needs to be improved. For example, Chinese Patent Publication No. CN115944476A discloses a multi-functional folding intelligent medical electric transfer machine for loading, transporting and rehabilitation training, including a column, a leg, a universal wheel, a boom and a retracting and extending mechanism. The retracting and extending mechanism includes a sheath, a parallelogram adjustment assembly, a first electric push rod and a limit pull rod. The telescopic end of the first electric push rod is rotatably connected to the front side of the column. A second electric push rod is rotatably connected to the side of the column away from the first electric push rod. The telescopic end of the second electric push rod is rotatably connected to the lower side of the boom. That is to say, the transfer machine of the above technical solution also has the boom hinged to the column, one end of the second electric push rod is hinged to the boom and the other end is hinged to the column. That is to say, there are also multiple hinged positions and the hinged positions are also directly exposed, and there is also a risk of clamping clothes or pinching fingers during use, and it is also possible to enter foreign objects, resulting in inconvenient use and the need to clean at all times.Therefore, it is necessary to develop a new type of foldable transfer machine to solve the above problems.

Detailed implementation manners

[0046] To make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0047] A foldable transfer machine according to an embodiment of the present utility model is shown in Figures 1 to 14, mainly including a chassis assembly 100, a flipping assembly 200, a swing arm assembly 300, and a clamping mechanism 400. The chassis assembly 100 includes a foot support 110 and universal wheels 120. The flipping assembly 200 is rotatably disposed above the foot support 110 and includes a frame 210 and an electric push rod 220. The swing arm assembly 300 is rotatably disposed at the upper end of the frame 210 and is rotatably connected to the driving end of the electric push rod 220. The clamping mechanism 400 is disposed at one end of the swing arm assembly 300 away from the frame 210, and the clamping mechanism 400 includes a mounting plate 410 connected to the swing arm assembly 300 and two clamping arm assemblies 420 disposed at both ends of the mounting plate 410. A clamping space for the patient to enter and be clamped is jointly defined between the mounting plate 410 and the two clamping arm assemblies 420. The foot support 110 is for the patient's feet to step on. The universal wheels 120 are disposed at the four corner positions of the bottom of the foot support 110 for driving the entire transfer machine to walk and move. The interior of the frame 210 is hollow and the bottom end is rotatably connected to the foot support 110. The lower end of the electric push rod 220 is hinged to the inner bottom of the frame 210, and the upper end of the electric push rod 220 extends towards the inner top of the frame 210 and is rotatably connected to the swing arm assembly 300. The frame 210 covers the rotating connection part between it and the swing arm assembly 300, improving the use safety and preventing particulate impurities such as dust from entering the interior of the frame 210 and affecting the normal operation of the rotating part and the driving end of the electric push rod 220. The mounting plate 410 is a vertically arranged quadrilateral plate with two opposite faces, one facing the swing arm assembly 300 (described as the back face), and the other facing the clamping space (described as the front face). The two clamping arm assemblies 420 are arranged oppositely for the patient's arms to rest on. In the embodiment of the present utility model, the flipping assembly 200 has a use state in which the frame 210 rotates around its rotation connection point with the foot support 110 to the vertical state and a folding state in which it rotates around its rotation connection point with the foot support 110 and lies flat on the foot support 110. For the transfer machine according to the embodiment of the present utility model, by the rotational connection between the flipping assembly 200 and the chassis assembly 100 and the rotational connection between the flipping assembly 200 and the swing arm assembly 300, the flipping assembly 200 can be flipped relative to the chassis to lie flat on the chassis assembly 100, and at the same time, the swing arm assembly 300 can rotate relative to the flipping assembly 200. On the one hand, during use, the clamping mechanism 400 connected to it can be rotated to achieve lifting, and on the other hand, when the flipping assembly 200 is flipped to the folding state, it also rotates so that the end of the swing arm assembly 300 is as flush with the lower end of the chassis assembly 100 as possible, reducing the overall size and significantly reducing the packaging size of the transfer machine.

[0048] According to some preferred embodiments of the present utility model, referring to Figure 4 and Figure 6 , at least one first connection hole 214 is opened at the bottom of the side surface of the frame 210 (that is, the left and right side surfaces as shown in Figure 1 )Figure 4 Preferably, two first connection holes 214 are provided on each side surface, and the two first connection holes 214 are not at the same horizontal height). Correspondingly, at least one second connection hole 1121 corresponding to the first connection hole 214 is formed on the foot support 110 (preferably, two second connection holes 1121 are provided on each side in the figure and the two second connection holes 1121 are not at the same horizontal height). In the embodiment of the present invention, the first connection hole 214 and the second connection hole 1121 serve as the rotation connection points between the frame 210 and the foot support 110. In the use state, the first connection hole 214 and the second connection hole 1121 are fixed by locking screws. In the folded state, first loosen the locking screws, and then turn the flipping assembly 200 over and lie flat on the chassis assembly 100.

[0049] The swing arm assembly 300 is provided to enable the clamping mechanism 400 installed at the end of the swing arm assembly 300 away from the flipping assembly 200 to be lifted and lowered vertically. When descending, it is convenient for patients, especially those with a lower height, to place their arms on the two clamping arm assemblies 420. When ascending, it enables the patient to switch from a knee-bent state to a standing state, making the patient switch to a more comfortable posture. According to some preferred embodiments of the present invention, the swing arm assembly 300 includes a swing rod 310, a swing shaft 320, and a first rotating connector 330. Among them, the swing rod 310 is a bent rod with multiple bends. More specifically, as Figure 5As shown, the swing rod 310 successively includes a vertical rod, an inclined rod, and a horizontal rod from bottom to top. The vertical rod is rotatably engaged with the frame 210, and one end of the horizontal rod away from the inclined rod is connected to the mounting plate 410 of the clamping mechanism 400. The swing shaft 320 is a cylindrical electric shaft horizontally installed at the bottom of the swing rod 310. The first rotating connector 330 is two first connecting pieces arranged in parallel and spaced apart on the side of the swing shaft 320 away from the swing rod 310, and the upper end of the electric push rod 220 is rotatably connected between the two first connecting pieces of the first rotating connector 330. The swing shaft 320 includes a shaft body 321 and T-shaped connecting shafts 322 fixed to the axial two ends of the shaft body 321 and having a diameter smaller than that of the shaft body 321. The two connecting shafts 322 are connected to the frame 210. Correspondingly, an avoidance hole 211 is opened on the outer side of the top end of the frame 210, and the avoidance hole 211 is matched with the swing shaft 320. More specifically, on both sides of the avoidance hole 211, there is a semi-circular connecting ear 212 protruding outward, and each connecting ear 212 is provided with a third connecting hole 215 for fixing the corresponding connecting shaft 322. A part of the shaft body 321 of the swing shaft 320 is exposed outside the avoidance hole 211, and the peripheral wall of the avoidance hole 211 is in rotational contact with the outer peripheral surface of the shaft body 321. That is to say, the swing shaft 320 and the frame 210 are in clearance-free (or the clearance is very small and can be ignored) fit. This solves the problem in the prior art that the articulated connection points are directly exposed, resulting in safety risks, and improves the use safety. It should be noted that the top end of the frame 210 in the embodiment of the present invention has two inclined surfaces forming an angle, and the two inclined surfaces correspond to the angles between the vertical rod and the inclined rod of the swing rod 310. When the swing rod 310 descends in place, the vertical rod and the inclined rod of the swing rod 310 respectively abut against the two inclined surfaces on the top surface of the frame 210. As Figure 1 and Figure 5 As shown, in order to realize the lifting of the clamping mechanism 400 driven by the swing arm assembly 300, an elevation control button 700 for controlling the rotation of the swing arm assembly 300 relative to the frame 210 to realize the lifting of the clamping mechanism 400 is further provided on the horizontal rod of the swing rod 310 of the clamping arm assembly 420 specifically. The elevation control button 700 is electrically connected to the swing shaft 320. It should be noted that the lifting of the swing arm assembly 300 in the embodiment of the present invention can also be controlled by a remote controller (not shown). Optionally, an emergency stop button (not shown) can also be provided on the swing rod 310 of the swing arm assembly 300.

[0050] According to some preferred embodiments of the present invention, a generally U-shaped handle 600 is further provided on the swing rod 310 of the swing arm assembly 300 specifically. The handle 600 is provided for the nursing workers and other personnel who push the transfer machine to hold.

[0051] For the frame 210, as Figures 2 to 4As shown, since components such as a motor are provided at the lower end of the electric push rod 220, such that the motor and the push rod form an L shape, the bottom end of the fixed frame 210 is wider than the top end. On the inner side wall surface of the inner side of the frame 210, a second rotating connector 213 is provided. Similar to the first rotating connector 330, the second rotating connector 213 includes two relatively arranged and spaced second connecting pieces. A transfer ear (not labeled) that is rotationally engaged with the space between the two second connecting pieces is provided at the bottom end of the electric push rod 220. Optionally, a socket (not labeled) for connecting a remote control and a charging socket (not labeled) are further provided on the frame 210. Optionally, the frame 210 is a frame body with an open bottom and a hollow interior, which is formed by connecting five sheet metal parts through components such as screws.

[0052] According to some preferred embodiments of the present invention, the clamping mechanism 400 is detachably connected to the swing arm assembly 300, specifically at one end of the swing rod 310 away from the frame 210. In the folded state, as Figure 14 shown, the clamping mechanism 400 is removed from the swing arm assembly 300, more specifically the swing rod 310, and placed on the chassis assembly 100. The length of the entire transfer machine in the folded state can be reduced, thereby further reducing the packaging size of the transfer machine. Further preferably, a knee rest 500 is provided on the inner side surface of the frame 210. The knee rest 500 is provided to facilitate the patient's leg to lean against when the clamping mechanism 400 descends to the lowest point in a bent state, protecting the patient's knees from being in hard contact with the frame 210 and causing injury. More preferably, the knee rest 500 is detachably connected to the frame 210. In the folded state, the knee rest 500 also needs to be removed and then placed on the frame 210 to avoid interference between the knee rest 500 and the chassis assembly 100 in the folded state. For the knee rest 500, as Figure 13 shown, it includes a knee pad 510 made of a flexible material such as sponge and a clamping member 520 provided on the back surface of the knee pad 510. The clamping member 520 is a U-shaped sheet metal part, and an inverted L-shaped clamping groove 521 is respectively formed on both sides of the clamping member 520. Correspondingly, a clamping protrusion (not labeled, such as a fastening bolt connected to the side surface of the frame 210) is respectively provided on the left and right side surfaces of the frame 210.

[0053] According to some preferred embodiments of the present invention, the clamping mechanism 400 is movable. More specifically, the arm assembly 420 can be subjected to a downward pressure force such as the patient's weight and rotate around its connection with the mounting plate 410 toward the direction of the other arm assembly 420. In other words, the arm assembly 420 can move downward and rotate to clamp the patient, thereby improving the patient's safety. As for the clamping mechanism 400, more specifically, the clamping mechanism 400 includes two arm assemblies 420 for the patient's left and right arms. The two arm assemblies 420 have the same structure, so one of the arm assemblies 420 is taken as an example for description. Specifically, Figures 7 to 12 As shown, any arm assembly 420 includes a guide shaft 421, an arm 422 and a fixed block 430. The guide shaft 421 is fixed vertically and tilted on the side of the mounting plate 410. More specifically, the upper ends of the two guide shafts 421 of the two arm assemblies 420 are wider than the lower ends. There is no limitation on the tilt angle of the guide shaft 421, and it can be selected and designed according to actual needs, such as 5°, 10°, etc. The arm 422 is slidably and rotatably arranged on the guide shaft 421. That is, the two arms 422 move downward under the downward pressure and rotate inwardly toward each other. The fixed block 430 is arranged on the outer side surface of the mounting plate 410, that is, on the back side, and the outer side surface of the fixed block 430 extends outwardly from top to bottom, so for the convenience of description this time, the outer side surface of the fixed block 430 is described as a driving inclined surface 431, that is, the upper end of the driving inclined surface 431 is closer to the back side of the mounting plate 410 than the lower end. The arm 422 is in sliding cooperation with the driving inclined surface 431. Since the driving inclined surface 431 is an inclined surface that slopes outward from top to bottom, the arm 422 will be deflected inward by the driving inclined surface 431 during the downward movement, thereby reducing the size of the clamping space to clamp the patient in the clamping space. There is no limitation on the angle of the driving inclined surface 431, and those skilled in the art can design it according to actual needs, such as 30° to the back of the mounting plate 410. In order to enable the arm 422 to always be in sliding cooperation with the driving inclined surface 431, a biasing member 440 needs to be provided between the arm 422 and the mounting plate 410. The purpose of the biasing member 440 is to apply a biasing force to the swing arm so that it always slides against the outer side surface of the fixed block 430. For the biasing member 440, it is preferably as follows Figure 11 The spring shown has its upper end mounted on the back side of the adjustment plate 450 and its lower end mounted on the back side of the mounting plate 410, and the spring is inclined. More specifically, the upper end of the two springs is wider than the lower end. More specifically, as Figure 12 As shown, the arm 422 is a substantially L-shaped plate, including a Figure 9The first plate 4221 extending from front to rear and the second plate 4222 located on the outside of the back of the mounting plate 410 and the sleeve or linear bearing 4223 arranged on the inner side of the bending part of the first plate 4221 and the second plate 4222, the linear bearing 4223 or the sleeve is slidably sleeved with the guide shaft 421, and the arm pad is sleeved on the first plate 4221. In order to realize the sliding cooperation between the arm 422 and the fixed block 430, a rotating cooperation component such as a protruding and extending toward the fixed block 430 is provided on the second plate 4222. Figure 8 or Figure 11 The bull's eye bearing 432 is shown. Further preferably, since the widest position between the two arms 422 is fixed, the applicability may need to be further improved for some patients with wider body widths. When the body width exceeds the widest position between the two arms 422, the patient cannot enter the clamping space, which makes the use uncomfortable or even impossible. Specifically, Figure 9 and Figure 10 As shown, the clamping mechanism 400 also includes two adjustment plates 450 that are slidably connected to both sides of the inner side surface of the mounting plate 410, and the two arm assemblies 420 are installed one by one at the ends of the two adjustment plates 450 that are away from each other. In the embodiment of the utility model, the two adjustment plates 450 can be adjusted directly by manually pulling them apart or pushing them together. Preferably, the adjustment of the two adjustment plates 450 is driven by a driving member. Specifically, the driving member is disposed on the mounting plate 410 and connected to the two adjustment plates 450, and is used for the user to operate to drive the two adjustment plates 450 to make horizontal movements closer to or away from each other.

Preferably, guide rails 480 extending along the moving direction of the two adjustment plates 450 are respectively provided on the upper and lower sides of the front of the mounting plate 410, and the upper and lower ends of the two adjustment plates 450 are respectively slidably matched with the two guide rails 480.

[0054] For the chassis assembly 100, the foot support 110 is not one or two flat plates. Figure 6 As shown, the foot support 110 includes two foot pedals 111 and an electrical box 112. The two foot pedals 111 are located on both sides of the electrical box 112. The middle part of each foot pedal 1110 is recessed downward to form a foot pedal portion 1110. The foot pedal portion 1110 is located lower than the ground, which is convenient for patients, especially those with limited mobility, to step on. It helps to reduce the workload of caregivers. Caregivers only need to slightly lift the patient's feet to place the patient's feet on the foot pedals 111. At the same time, the foot pedal portion 1110 can also be used as a place to place the clamping mechanism 400 in a folded state. The second connecting holes 1121 on the foot support 110 are provided on both side surfaces of the electrical box 112. The length of the electrical box 112 is smaller than the length of the two foot pedals 111 so that a U-shaped inwardly recessed opening is formed between the two foot pedals 111 and the rear end of the electrical box 112. The setting of the opening allows the transfer machine to be directly docked with the toilet, making it convenient for patients to go to the toilet. Figure 2 As shown, a battery 800 (exemplarily, a lithium battery 800 ) and a circuit board (exemplarily, a PCB circuit board, not shown) are also provided inside the electrical box 112 . The battery 800 is used to power electrical components such as the electric push rod 220 . The battery 800 can be charged through the charging socket on the frame 210 .
