Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a horizontal stepping rehabilitation training device. Background Technology

[0002] Lower limb rehabilitation training is a crucial pathway for patients with lower limb functional impairment to restore motor perception and ultimately achieve rehabilitation. Traditional lower limb rehabilitation training primarily relies on therapists manually assisting patients in joint exercises. This process is time-consuming and labor-intensive, often requiring multiple therapists, resulting in high training costs. Furthermore, the treatment effectiveness is unstable due to variations in therapist skill levels and physical condition. Therefore, the use of lower limb rehabilitation training equipment in patient care and rehabilitation training is becoming increasingly common. Currently, lower limb rehabilitation training devices on the market are either too simple in structure and limited in function, or too complex in structure, excessively large in size, and inconvenient to transport and move. Summary of the Invention

[0003] The purpose of this invention is to provide a recumbent stepping rehabilitation training device that is easy to transport and transfer, easy to adjust, and has a variety of functions.

[0004] The technical solution provided by this invention is as follows:

[0005] A supine stepping rehabilitation training device includes:

[0006] The base frame assembly includes a front bracket and a rear bracket, wherein the rear bracket is detachably connected to the front bracket;

[0007] Interactive components are mounted on the front support.

[0008] The bed adjustment assembly is mounted on the rear support.

[0009] The bed frame assembly is rotatably connected to the bed frame adjustment assembly;

[0010] Two leg training components are respectively located on both sides of the bed assembly along the width direction.

[0011] In some embodiments, the bed adjustment assembly includes a scissor lift mechanism and a lifting push rod. The bottom end of the scissor lift mechanism is connected to the rear support, and the top end is hinged to the bed assembly via a hinge seat and a hinge. One end of the lifting push rod is fixed to the top end of the scissor lift mechanism, and the other end is fixed to the bed assembly.

[0012] In this technical solution, the bed frame lifting mechanism adopts a scissor lift, which, compared with the quadrilateral linkage tilting lifting mechanism, can keep the front and rear positions of the bed frame unchanged and lift vertically, ensuring that the center of gravity of the bed frame does not shift, and making the load-bearing capacity safer and more reliable.

[0013] In some embodiments, the leg training assembly includes a leg support swing arm mechanism, which includes a drive component, a swing arm adjustment mechanism, a leg support adjustment mechanism, and a leg support. The drive component is disposed on the bed assembly, and the swing arm adjustment mechanism is connected to the drive component and located outside the bed assembly. The drive component drives the swing arm adjustment mechanism to rotate about the width of the bed assembly. One end of the leg support adjustment mechanism is connected to the swing arm adjustment mechanism, and the other end is connected to the leg support.

[0014] In this technical solution, the swing arm adjustment mechanism is located on the outside of the bed. Compared with the four-bar flipping mechanism built into the bottom of the bed, it has a larger effective training range and is applicable to a wider range of training postures. At the same time, the swing arm adjustment mechanism is located on the outside, making adjustment more convenient. The leg support can adapt to changes during the process of lifting the thigh and raising the leg, ensuring that the straps will not slip off.

[0015] In some embodiments, the swing arm adjustment mechanism includes an adapter, a mounting base, a knob plunger, a slider, and a first spring;

[0016] The adapter is fixedly connected to the output shaft of the drive component. The mounting base is provided with multiple adjustment holes along the length of the bed assembly. The knob plunger passes through the adapter and is fixed in any one of the adjustment holes on the mounting base to fix the mounting base and the adapter.

[0017] One end of the sliding member is slidably disposed on the mounting base along the length direction of the bed assembly, and the other end of the sliding member is connected to the leg support adjustment mechanism. One end of the first spring is connected to the sliding member, and the other end is connected to the mounting base.

[0018] In this technical solution, the swing arm adjustment mechanism uses springs for tension assistance, which can help users better complete the reciprocating motion within the stepping cycle. The leg support spacing can be quickly adjusted to adapt to the user's body shape, ensuring the safety and comfort of the user during training.

[0019] In some embodiments, the leg rest adjustment mechanism includes an L-shaped bracket, an adjustment rod, and a rotary plunger. The L-shaped bracket is connected to the sliding member and is perpendicular to the sliding direction of the sliding member. The adjustment rod has multiple adjustment holes along the width direction of the bed assembly. The rotary plunger passes through the L-shaped bracket and is fixed in any one of the adjustment holes of the adjustment rod. The leg rest is connected to the adjustment rod; or;

[0020] The leg support adjustment mechanism includes an L-shaped bracket, an adjusting rod, a lead screw assembly, and a limiting member. The L-shaped bracket is connected to the sliding member and is arranged perpendicular to the sliding direction of the sliding member. One end of the adjusting rod is connected to the L-shaped bracket through the lead screw assembly, and the leg support is connected to the other end of the adjusting rod. The limiting member is disposed on the lead screw of the lead screw assembly.

[0021] In some embodiments, the leg training assembly further includes a leg extension mechanism and a pedal mechanism. The leg extension mechanism is disposed on the bed assembly and is extendable along the length of the bed assembly. The pedal mechanism is connected to the leg extension mechanism.

[0022] In some embodiments, the leg extension mechanism includes a connector, a second spring, a follower slide, and a tension sensor connected sequentially along the length of the bed assembly. The connector is fixed to the bed assembly, the follower slide is movably disposed on the bed assembly along the length of the bed assembly, the pedal mechanism is connected to the follower slide, one end of the tension sensor is fixed to the bed assembly, and the other end is fixedly connected to the second spring; and / or;

[0023] The pedal mechanism includes a pedal adjustment mechanism, a connecting bracket, and pedals. The pedal adjustment mechanism includes a plunger plate, an adjustment block, a knob plunger, a clamping plate, and a ball joint. The plunger plate is connected to the follower slide plate. The adjustment block has multiple adjustment holes along the width direction of the bed assembly. The adjustment block is disposed on the plunger plate. The knob plunger passes through any one of the adjustment holes of the plunger plate and the adjustment block to adjust the distance between the left and right pedals.

[0024] The clamp is fixed on the adjusting block, the ball head of the ball joint is located between the adjusting block and the clamp, one end of the connecting bracket is connected to the ball joint, and the other end is connected to the pedal.

[0025] In some embodiments, the bed assembly includes a main bed and a backrest mechanism, the main bed being rotatably connected to the bed adjustment assembly, and the backrest mechanism being rotatably connected to the main bed.

[0026] In some embodiments, the main bed body includes a main bed frame, leg supports, and an electric push rod, wherein the leg supports are connected to and retractable relative to the main bed frame, and one end of the electric push rod is connected to the main bed frame and the other end is connected to the leg supports; and / or;

[0027] The backplate mechanism includes a pitch push rod, a backplate, a suspension frame, and suspension straps. One end of the pitch push rod is hinged to the main bed body, and the other end is hinged to the backplate. The suspension straps are fixed to the upper end of the backplate by the suspension frame.

[0028] In some embodiments, the back panel mechanism further includes two arm support mechanisms, which are disposed on both sides of the back panel along the width direction. Each arm support mechanism includes a stop bar, a rear bracket, a middle bracket, a front bracket, and an arm support. The stop bar is disposed on the back panel and has multiple adjustment holes along the length direction of the back panel. The front bracket, the middle bracket, and the rear bracket are connected in series and hinged. The rear bracket is fixed in any one of the adjustment holes of the stop bar, and the arm support is fixedly connected to the front bracket.

[0029] In this technical solution, users can optionally equip the armrest component. The three-bar linkage structure allows adjustment of the armrest's distance from the bed frame in all directions, accommodating users with different back thicknesses and shoulder widths. Locking mechanisms can be added at the linkage hinges to prevent the armrest from shifting. Compared to the small table on a typical standing bed, the open structure provides more chest space, making it easier for users to get off. The armrest can be made of soft materials such as foam for added comfort.

[0030] The technical advantages of this invention are as follows: the base frame assembly adopts a modular design, and the equipment can be separated into front and rear parts after the front and rear supports are disassembled, greatly reducing the volume and ensuring that it can be used in ordinary elevators, avoiding the limitations of the equipment's usage site, and facilitating transfer and transportation; the bed assembly is rotatably connected to the bed adjustment assembly, which can adjust the tilt angle of the bed assembly to help patients overcome gravity and gradually carry out lower limb training, with a wide range of application scenarios; the leg training assembly can realize the patient's lower limb stepping rehabilitation training, with rich functions.

[0053] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0054] To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of components with the same structure or function is shown schematically, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one".

[0055] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0056] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0057] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0058] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, a supine stepping rehabilitation training device includes a base frame assembly 10, an interactive component 20, a bed adjustment component 30, a bed assembly, and two leg training components. The base frame assembly 10 includes a front support 11 and a rear support 12, with the rear support 12 detachably connected to the front support 11. The interactive component 20 is mounted on the front support 11. The bed adjustment component 30 is mounted on the rear support 12. The bed assembly and the bed adjustment component 30 are rotatably connected, and the bed assembly can support the user. The bed adjustment component 30 adjusts the height and tilt angle of the bed assembly. The two leg training components are respectively located on both sides of the bed assembly along its width, driving the user to perform reciprocating leg-raising movements.

[0059] Specifically, the base frame assembly 10 includes a front support 11 and a rear support 12. The front support 11 and the rear support 12 are detachably connected. A portion of the components of the horizontal stepping rehabilitation training device are mounted on the front support 11, and another portion is mounted on the rear support 12. During transfer and transportation, the front support 11 and the rear support 12 can be separated into front and rear parts, ensuring that the device can enter and exit ordinary elevators and avoiding limitations on the usage site of the device. Universal casters are installed under the base frame assembly 10 to ensure convenient equipment transfer.

[0060] Interactive component 20 is mounted on the front support 11. It allows interaction with the patient during training, providing visual feedback and enhancing the training's enjoyment and experience. Dual displays enable visual interaction, including quick settings by the therapist within the software interface and interactive games, further increasing training engagement. Interactive component 20 includes a support column 21, an interactive screen 22, and an interactive panel 23. One end of the support column 21 is connected to the front support 11, while the interactive screen 22 and interactive panel 23 are located at the other end. When the bed assembly is in a standing position, the interactive screen 22 faces the backrest mechanism 50, and the interactive panel 23 is positioned below it. The interactive screen 22 can be a touchscreen or a keyboard-operated display. The patient can use the touchscreen or display for visual interaction, and the therapist or patient can use the interactive screen 22 for interface settings. The interactive panel 23 can be a control panel with buttons, and may also include a handheld controller with buttons for quick equipment adjustments. Furthermore, the interactive component 20 also includes an emergency stop component, which includes a press-to-stop and a handheld-to-stop mechanism, providing dual protection for the safety of device use.

[0061] The bed adjustment component 30 can adjust the height of the bed component, making it easier for patients to transfer to the machine in a low position and to train in a high position. The bed adjustment component 30 can also adjust the pitch angle of the bed component, so that the bed component can be adjusted from a lying position to a standing position. The pitch angle of the bed component can also be adjusted according to the patient's lower limb muscle strength, helping the patient overcome gravity and gradually carry out lower limb training.

[0062] The bed assembly includes a main bed frame 40 and a backrest mechanism 50. The main bed frame 40 is rotatably connected to a bed adjustment assembly 30 to support the user's lower body. The bed adjustment assembly 30 is used to adjust the height and tilt angle of the main bed frame 40. The backrest mechanism 50 is rotatably connected to the main bed frame 40, making the tilt angle of the backrest mechanism 50 relative to the main bed frame 40 adjustable. The backrest mechanism 50 stabilizes the patient's upper body, allowing them to stand for lower limb training.

[0063] Two leg training components are located on either side of the bed frame and serve as the power transmission structure for lower limb stepping, enabling patients to perform reciprocating leg-raising movements for leg-raising training. The leg training components include a leg support swing arm mechanism 60 and a pedal mechanism 70. The leg support swing arm mechanism 60 is used to stabilize the user's thighs to drive the user in reciprocating leg-raising movements, while the pedal mechanism 70 is used to stabilize the user's feet.

[0064] When patients are training, the height of the bed assembly can be lowered first to facilitate the transfer of the patient onto the bed assembly. Then, the patient's upper body is fixed by the backrest mechanism 50, the patient's thighs are fixed by the leg support swing arm mechanism 60, and the patient's feet are fixed by the pedal mechanism 70. Next, the bed assembly is raised and tilted so that the bed assembly changes from a lying position to a tilted or standing position. Then, the leg training assembly helps the patient to perform leg raising exercises to achieve the patient's lower limb rehabilitation training.

[0065] In this embodiment, the base frame assembly 10 adopts a modular design. After the front support 11 and the rear support 12 are disassembled, the equipment can be separated into front and rear parts, greatly reducing its volume and ensuring that it can be used in ordinary elevators. This avoids the limitation of the equipment's usage space and facilitates transfer and transportation. The bed adjustment assembly 30 can lower the bed assembly to a lower position, making it easier for patients to transfer from wheelchairs to the machine. The bed adjustment assembly 30 can also adjust the bed assembly from a lying position to a standing position. It can adjust the tilt angle of the bed and the pitch angle of the backrest according to the patient's lower limb muscle strength, helping the patient overcome gravity and gradually carry out lower limb training. It has a wide range of usage scenarios. The leg training assembly can realize the patient's lower limb stepping rehabilitation training, with rich functions.

[0066] In some embodiments, such as Figure 3 and Figure 4As shown, the bed adjustment assembly 30 includes a scissor lift mechanism 31 and a lifting push rod 35. The bottom end of the scissor lift mechanism 31 is connected to the rear support 12, and the top end of the scissor lift mechanism 31 is connected to the upper support 32 for driving the upper support 32 to rise and fall. The upper support 32 is hinged to the main bed 40 through a hinge seat 33 and a hinge 34. One end of the lifting push rod 35 is fixed to the upper support 32, and the other end is fixed to the main bed 40 for adjusting the pitch angle of the main bed 40.

[0067] The scissor lift mechanism 31 includes four intersecting rods symmetrically arranged on both sides of the upper support 32 and the rear support 12. One side of each intersecting rod is hinged to the rear support 12 and the upper support 32, respectively, while the other side slides on the upper support 32 and the rear support 12 via a guide rail slider to form the scissor lift mechanism 31. The height of the upper support 32 is adjusted by moving the slider through a linear actuator, such as an electric push rod. Compared with the quadrilateral linkage tilting lift mechanism, the scissor lift mechanism 31 can maintain the front-to-back position of the bed while lifting vertically, ensuring that the center of gravity of the bed does not shift, and making the load-bearing capacity safer and more reliable.

[0068] The main bed 40 and the upper support 32 are hinged together by the hinge seat 33 and the hinge 34. One end of the lifting push rod 35 is fixed on the upper support and the other end is fixed on the main bed 40. Using the lever principle, the main bed 40 can be rotated within a 90-degree range from horizontal to standing.

[0069] To ensure safety, prevent shearing hazards, optimize appearance, and improve the overall integrity of the equipment, the bed adjustment assembly 30 also includes a protective cover over the scissor lift mechanism 31, such as... Figure 5 As shown, the protective cover includes a bottom shell 36, a middle shell 37, and an upper shell 38 connected in sequence. The opening sizes of the bottom shell 36, the middle shell 37, and the upper shell 38 decrease sequentially, so that the bottom shell 36 can accommodate the middle shell 37, and the middle shell 37 can accommodate the upper shell 38. The bottom shell 36 is mounted on the rear support 12, and the upper shell 38 is connected to the upper support 32. When the scissor lift mechanism 31 lifts and lowers, it drives the protective cover to lift and lower together.

[0070] Furthermore, to improve the uniformity of the lifting and lowering of the bottom shell 36, the middle shell 37, and the upper shell 38, such as... Figure 5 As shown, the protective cover also includes a telescopic mechanism 39. The telescopic mechanism 39 comprises two linkage groups. Each linkage group includes a lower linkage 391, a middle linkage 392, and an upper linkage 393, which are hinged sequentially. The bottoms of the two lower linkages 391 are hinged to a lower hinge, which is fixed to the rear support 12 or the bottom shell 36. The middle sections of the two middle linkages 392 are hinged to a middle hinge, which is fixed to the middle shell 37. The tops of the two upper linkages 393 are hinged to an upper hinge, which is fixed to the upper shell 38. When the scissor lift mechanism 31 lifts and lowers, it drives the middle shell 37 and the upper shell 38 to lift and lower the bottom shell 36 evenly.

[0071] In some embodiments, such as Figure 6 and Figure 7 As shown, the leg rest swing arm mechanism 60 includes a drive component 61, a swing arm adjustment mechanism 62, a leg rest adjustment mechanism 63, and a leg rest 64. The drive component 61 is disposed on the main bed body 40. The swing arm adjustment mechanism 62 is connected to the drive component 61 and located outside the main bed body 40. It is used to adjust the distance between the leg rest 64 and the drive component 61. The drive component 61 drives the swing arm adjustment mechanism 62 to rotate around the width direction of the main bed body 40 to realize the reciprocating motion of raising the thigh. One end of the leg rest adjustment mechanism 63 is connected to the swing arm adjustment mechanism 62, and the other end is connected to the leg rest 64. It is used to adjust the distance between the two leg rests 64.

[0072] The drive component 61 includes a motor and a reducer. The motor amplifies the torque through the reducer and uses it as a power source to drive the swing arm adjustment mechanism 62 to reciprocate. The swing arm adjustment mechanism 62 drives the leg support adjustment mechanism 63 and the leg support 64 to rotate together. The leg support 64 is tied to the middle of the patient's thigh with straps, which drives the thigh to lift and move back and forth to realize the lower limb stepping training.

[0073] The swing arm adjustment mechanism 62 is used to adjust the distance between the leg rest 64 and the drive component 61. By moving the swing arm adjustment mechanism 62 forward and backward according to the patient's body shape, the position of the leg rest 64 connected to the swing arm adjustment mechanism 62 relative to the patient's thigh can be adjusted. This position adjustment allows for matching different body types, ensuring correct training posture, effective training angle, and comfortable training process. The leg rest adjustment mechanism 63 can adjust the leg rest 64 left and right along the width of the main bed 40 to adjust the distance between the two leg rests 64.

[0074] like Figure 7 As shown, the swing arm adjustment mechanism 62 includes an adapter 621, a mounting base 622, a knob plunger 623, a slider 624, and a first spring 625. The adapter 621 is fixedly connected to the output shaft of the drive component 61. The mounting base 622 has multiple adjustment holes along the length of the main bed 40. The knob plunger 623 passes through the adapter 621 and is fixed in any one of the adjustment holes on the mounting base 622 to fix the mounting base 622 and the adapter 621 and adjust the position of the mounting base 622 along the length of the main bed 40. One end of the slider 624 is slidably disposed on the mounting base 622 along the length of the main bed 40. One end of the first spring 625 is connected to the slider 624, and the other end is connected to the mounting base 622 to reset the slider 624. The other end of the slider 624 is connected to the leg rest adjustment mechanism 63. In this embodiment, the first spring 625 can be a compression spring or a tension spring.

[0075] The adapter 621 has a C-shaped structure. It engages with the mounting base 622 and is secured by a rotary plunger 623. The mounting base 622 has multiple adjustment holes. The rotary plunger 623 connects to and locks with different adjustment holes to adjust the front-to-back position of the mounting base 622, thereby adjusting the position of the leg rest 64 along the length of the main bed 40. The sliding member 624 slides on the mounting base 622, allowing the entire swing arm adjustment mechanism 62 to extend and retract, compensating for positional changes during the leg-raising and lowering process. The sliding member 624 utilizes a first spring 625 to ensure its return to its original position, and simultaneously overcomes the weight of the structural components in a standing posture, preventing the leg rest 64 from sagging.

[0076] like Figure 7 As shown, the mounting base 622 includes an adjusting plate 6221, a base plate 6222, a front side plate 6223, and a rear side plate 6224. The swing arm adjusting mechanism 62 also includes a slider 626 and a guide post 627. The adjusting plate 6221 has multiple adjusting holes along the length of the main bed 40. The knob plunger 623 passes through the adapter 621 and is fixed in any one of the adjusting holes on the adjusting plate 6221. The base plate 6222 is fixedly connected to the adjusting plate 6221, and the front side plate 6223 is disposed on the base plate 6224. The front and rear side plates 6224 of the 222 are located on the rear side of the base plate 6222. A slider 626 is slidably mounted on the base plate 6222 along its length, and the slider 624 passes through the rear side plate 6224 and is connected to the slider 626. One end of a guide post 627 is connected to the front side plate 6223, and the other end is connected to the rear side plate 6224. A first spring 625 is sleeved on the guide post 627, with one end connected to the slider 624 and the other end connected to the rear side plate 6224. Different lengths of the slider 624 extending beyond the rear side plate 6224 allow for variations in the overall length of the swing arm adjustment mechanism 62.

[0077] It should be noted that the forward and backward position compensation of the swing arm adjustment mechanism 62 is not limited to the above-mentioned one implementation method, such as... Figure 8 As shown, sliding structures such as guide rails and optical axes can also be used to achieve forward and backward position compensation. The first spring 625 can also be a constant force spring 6251. Using a constant force spring 6251 can make the spring auxiliary force more stable. The leg support can also be made of a soft, covering material to prevent slippage and adapt to changes.

[0078] Preferably, such as Figure 7 As shown, the swing arm adjustment mechanism 62 also includes a limiting plate 628, which is installed at the output end of the drive component 61 and is used to limit the rotation angle of the drive component 61. The limiting plate 628 is installed at the power output end of the drive component 61 to limit the rotation range of the swing arm adjustment mechanism 62, ensuring the safety of hip joint movement and preventing muscle and joint damage.

[0079] like Figure 7As shown, the leg support adjustment mechanism 63 includes an L-shaped bracket 631, an adjusting rod 632, and a rotary plunger. The L-shaped bracket 631 is connected to the sliding member 624 and is perpendicular to the sliding direction of the sliding member 624. The adjusting rod 632 has multiple adjusting holes along the width direction of the main bed body 40. The rotary plunger passes through the L-shaped bracket 631 and is fixed in any one of the adjusting holes of the adjusting rod 632. The leg support 64 is connected to the adjusting rod 632. The relative distance between the adjusting rod 632 and the L-shaped bracket 631 is positioned and locked using the rotary plunger and the adjusting holes on the adjusting rod 632. The leg support 64 is connected to the adjusting rod 632, and the leg support 64 can rotate at a small angle relative to the adjusting rod 632 to ensure that the leg support 64 adapts to changes in the rotation angle during the process of lifting the thigh and leg, ensuring that the straps will not slip.

[0080] As a variation, a linear screw mechanism can also be used to adjust the position of the leg support 64. Specifically, for example... Figure 9 As shown, the leg support adjustment mechanism 63 includes an L-shaped bracket 631, an adjusting rod 632, a lead screw assembly, and a limiting member 633. The lead screw assembly includes a lead screw 634 and a lead screw nut 635. The L-shaped bracket 631 is connected to the sliding member 624 and is perpendicular to the sliding direction of the sliding member 624. One end of the adjusting rod 632 is connected to the L-shaped bracket 631 through the lead screw assembly, and the leg support 64 is connected to the other end of the adjusting rod 632. The limiting member 633 is provided on the lead screw 634 of the lead screw assembly to limit the position of the adjusting rod 632 and prevent the adjusting rod 632 from coming off the lead screw 634.

[0081] Existing technologies often employ a lead screw linear drive unit push-pull four-bar linkage mechanism for tilting, raising, and lowering the leg rest 64. The power mechanism is built into the bed frame, and the tilting angle and compensating stroke are limited by the linkage, making it difficult to achieve a wide range of leg-raising angles. Furthermore, because the mechanism is located under the user's legs, adjustment is inconvenient. In this embodiment, the swing arm adjustment mechanism 62 is located on the outside of the main bed frame 40. The tilting angle and compensating stroke are not limited, allowing for a wide range of leg-raising angles, and adjustment is convenient.

[0082] Furthermore, such as Figure 10 As shown, the leg training component also includes a leg extension mechanism 80 corresponding to the pedal mechanism 70. The two leg extension mechanisms 80 are respectively mounted on the main bed 40 and are movable along the length of the main bed 40, used to adjust the position of the pedal mechanism 70 along the length of the main bed 40. The leg extension mechanism 80 can adjust the pedal position to match the different heights and leg lengths of patients, ensuring that the patient is in an effective leg-raising training position.

[0083] The leg extension mechanism 80 includes a connector 81, a second spring 82, a follower slide 83, and a tension sensor 84, which are sequentially connected along the length of the main bed 40. The connector 81 is fixed to the main bed 40, and the follower slide 83 is movably mounted on the main bed 40 along its length. The pedal mechanism 70 is connected to the follower slide 83. One end of the tension sensor 84 is fixed to the main bed 40, and the other end is fixedly connected to the second spring 82. It is used to measure the force exerted by the user's lower limbs on the pedal. During training, the patient is in a standing position, and the patient's foot exerts a force on the pedal. The tension sensor 84 can measure the force between the patient's foot and the pedal to assess the patient's muscle strength and the symmetrical recovery of the left and right legs.

[0084] like Figure 11 As shown, the pedal mechanism 70 includes a pedal adjustment mechanism 71, a connecting bracket 72, and pedals 73. One end of the pedal adjustment mechanism 71 is connected to the follow-up slide plate 83, and the other end is connected to the pedals 73 through the connecting bracket 72. It is used to adjust the distance between the two pedals 73 to accommodate the foot spacing of users of different body types, ensuring training safety and comfort.

[0085] like Figure 11 As shown, the pedal adjustment mechanism 71 includes a plunger plate 711, an adjustment block 712, a knob plunger, a clamping plate 713, and a ball head component 714. The plunger plate 711 is connected to the follower slide plate 83. The adjustment block 712 has multiple adjustment holes along the width direction of the main bed 40. The adjustment block 712 is set on the plunger plate 711. The knob plunger passes through any one of the adjustment holes of the plunger plate 711 and the adjustment block 712 to adjust the distance between the left and right pedals 73. The clamping plate 713 is fixed on the adjustment block 712. The ball head of the ball head component 714 is set between the adjustment block 712 and the clamping plate 713. One end of the connecting bracket 72 is connected to the ball head component 714, and the other end is connected to the pedal 73.

[0086] In this embodiment, the left and right positions of the pedal 73 are locked using the knob plunger on the plunger plate 711 and the adjustment hole on the adjustment block 712. A ball joint structure is formed between the clamping plate 713 and the adjustment block 712, allowing the upper pedal component to flexibly adapt to the user's foot joints. A handle 715 is connected to the clamping plate 713, and the handle 715 is clamped and fixed to avoid joint and muscle damage. The pedal 73 is connected to the adjustment block 712 through the connecting bracket 72 and the ball joint 714. The pedal 73 can rotate freely relative to the adjustment block 712, and the spatial position of the pedal 73 can be adjusted using the ball joint 714 to adapt to the patient's foot joint deformity. The pedal 73 adopts an open buckle design at the front and rear, allowing the front and rear straps to be quickly wrapped and unwrapped, avoiding the inconvenience of traditional buckle-type operation.

[0087] Furthermore, such as Figure 11As shown, the pedal mechanism 70 also includes a buffer pad 74, which is mounted on the connecting bracket 72. The pedal 73 is mounted on the buffer pad 74 and its front end is hinged to the end of the connecting bracket 72 away from the adjusting block 712. The front end of the pedal 73 is hinged to the connecting bracket 72. When the lower limb lifts its leg to form a tiptoe stepping motion, the pedal 73 can be lifted and lowered simultaneously to complete the follow-up support. The buffer pad 74 can play a buffering role when the pedal 73 returns to its original position.

[0088] In some embodiments, such as Figure 10 As shown, the main bed body 40 includes a main bed frame 41, a leg support 42, and an electric push rod 43. The leg support 42 is connected to the main bed frame 41 and is retractable relative to the main bed frame 41. One end of the electric push rod 43 is connected to the main bed frame 41, and the other end is connected to the leg support 42, used to adjust the length of the leg support 42 extending out of the main bed frame 41. The leg support 42 slides retractably relative to the main bed frame 41 via a guide rail slider, with the electric push rod 43 used for adjustment. In actual use, the force between the patient's feet and the footrest 73 can also be adjusted by adjusting the length of the leg support 42 extending out of the main bed frame 41.

[0089] The lower part of the leg frame 42 is equipped with a guide rail slider structure. The follower slide 83 is movably mounted on the leg frame 42 through the guide rail slider structure, and the second spring 82 is used to improve the restoring force, so that the pedal mechanism 70 can move up and down back and forth when the patient's lower limbs push off.

[0090] In one embodiment, the backrest mechanism 50 includes a pitch lever 51, a backrest 52, a suspension frame 53, and suspension straps 54. One end of the pitch lever 51 is hinged to the main bed body 40, and the other end is hinged to the backrest 52, used to adjust the pitch angle of the backrest 52. The suspension straps 54 are fixed to the upper end of the backrest 52 via the suspension frame 53. The suspension straps 54 can fix the patient, ensuring the patient's safety, while also assisting the patient in overcoming gravity and standing to perform lower limb training.

[0091] In some embodiments, such as Figure 2 As shown, the backplate mechanism 50 also includes two arm support mechanisms 55, such as... Figure 12 As shown, two arm support mechanisms 55 are located on both sides of the back plate 52 along the width direction. The arm support mechanisms 55 can provide upper limb support for patients undergoing standing training, assist patients in maintaining balance and ensuring safety, while avoiding joint and muscle damage caused by poor upper limb posture.

[0092] The arm support mechanism 55 includes a stop bar 551, a rear bracket 552, a middle bracket 553, a front bracket 554, and an arm support 555. The stop bar 551 is mounted on the back panel 52 and has multiple adjustment holes along the length of the back panel 52. The front bracket 554, middle bracket 553, and rear bracket 552 are connected in series and hinged together. The rear bracket 552 is fixed in any one of the adjustment holes of the stop bar 551. The arm support 555 is fixedly connected to the front bracket 554. The front, middle, and rear brackets 552 are connected in series and hinged together to form a three-bar linkage, which can adjust the distance of the arm support 555 relative to the bed frame in all directions to accommodate users with different back thicknesses and shoulder widths. A locking mechanism can be added at the hinge joints of the linkage to prevent the arm support 555 from shifting. The groove of the rear bracket 552 is engaged with the stop bar 551 and locked in place using a screw handwheel.

[0093] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
