[0029] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.
[0030] Example 1
[0031] Please refer to Figures 1 to 10. The present invention preferably provides the following technical solution: a wheeled exoskeleton rehabilitation support device, comprising: a movable frame structure; a seat cushion 2 disposed on the movable frame structure for supporting the patient's buttocks; and a leg support mechanism disposed on the front side of the movable frame structure for supporting the patient's legs; and further comprising a gait simulation mechanism disposed on the front and rear sides of the movable frame structure for simulating human walking gait. When the gait simulation mechanism imitates human walking, the leg support mechanism synchronously drives the patient's legs to move forward alternately to perform rehabilitation training on the patient's legs.
[0032] In this embodiment, as shown in Figures 1-4, the leg support mechanism located on the front side of the movable frame structure, in conjunction with the gait simulation mechanisms located on the front and rear sides of the movable frame structure, allows the patient to perform passive leg training when both are powered on. When the leg support mechanism is not powered on, the patient can perform active leg training, thus achieving both active and passive rehabilitation training for the patient's legs. Furthermore, if the patient's leg stability is insufficient, the patient can sit on the cushion 2 located on the upper surface of the movable frame structure to achieve leg mobility training in a seated position. This design can also serve as a walking wheelchair for the patient's daily mobility at home, thereby achieving leg rehabilitation training while reducing inconvenience in the patient's daily life.
[0033] Furthermore, the movable frame mechanism includes a support base 1, a cushion 2 disposed on the upper surface of the horizontal section of the support base 1, and mounting frames 3 respectively disposed on both sides of the vertical section of the support base 1. Two mounting plates 4 are respectively disposed on the opposite side of the mounting frames 3 and the support base 1. Each mounting plate 4 is equipped with a support wheel structure at its bottom for supporting the operation of the movable frame mechanism. Each support wheel structure includes a second electric telescopic rod 20 fixed to the bottom of the mounting plate 4, and a universal wheel 21 disposed at the telescopic end of the second electric telescopic rod 20.
[0034] As shown in Figure 1, the movable frame structure can be used when the gait simulation mechanism retracts and the second electric telescopic rod 20 extends, so that the device can be used as a wheelchair. The universal wheel 21 is equipped with a braking system, which is existing technology. During daily leg training, it can be adjusted according to the patient's condition. When it is extended and flush with the bottom of the gait simulation mechanism, it can serve as a support structure to increase the stability of the patient during training.
[0035] Example 2
[0036] In another embodiment of the present invention, the gait simulation mechanism is provided in two sets, which are respectively placed on the front and rear sides of the two sets of mounting plates 4 distributed in front and behind; each set of gait simulation mechanism includes two sets of sliding block assemblies and a support rod structure provided on each set of sliding block assemblies; it also includes a transmission rod structure provided on each set of sliding block assemblies, and the transmission rod structure is used to drive the support rod structure to run horizontally and vertically on the sliding block assemblies to simulate the support phase and swing phase of the human body.
[0037] In this embodiment, two sets of gait simulation mechanisms are provided and distributed on the front and rear sides of the movable frame structure, as shown in Figures 1 and 2. Each set of gait simulation mechanisms includes two sets of sliding block assemblies and a support rod structure set on each set of sliding block assemblies. The support rod structure is used as a walking leg. When the transmission rod structure set on the sliding block assembly is running, it can drive the support rod structure to move vertically or horizontally. The support rod structure on the same side moves forward alternately, and the two sets of support rod structures on the oblique side move synchronously to simulate the support phase and swing phase of human leg walking, thereby realizing the forward stride, support, and backward lift movements.
[0038] Furthermore, the slide block assembly includes a mounting bracket 5 fixed to the outer wall of the mounting plate 4, a connecting bracket 6 fixed to the side wall of the mounting bracket 5, and a first slide block 22 opened on the outer side of the connecting bracket 6, as well as a movable plate 8 disposed inside the first slide block 22. It also includes a second slide block 16 opened at the lower part of the movable plate 8, and the second slide block 16 is perpendicular to the first slide block 22. A slider body 17 is also disposed inside the second slide block 16. It also includes a limiting frame 19 fixed to the side wall of the slider body 17, and the support rod structure can move up and down inside the limiting frame 19.
[0039] As shown in Figures 5 and 6, since the movable plate 8 is slidably installed inside the first slide groove 22, and the slider body 17 is slidably installed inside the second slide groove 16, and the second slide groove 16 is perpendicular to the first slide groove 22, and the support rod structure is connected to the slider body 17 through the limiting frame 19, when the transmission rod structure drives the support rod structure to run, the slider body 17 can move horizontally inside the second slide groove 16, and the movable plate 8 can move vertically inside the first slide groove 22, further enabling the support rod structure to move horizontally and vertically.
[0040] Furthermore, the support rod structure includes a support rod body 13, which is slidably installed inside the limiting frame 19, and two first electric telescopic rods 14 fixed to the bottom of the support rod body 13, with a support plate 15 fixed to the telescopic end of each first electric telescopic rod 14.
[0041] As shown in Figure 5, the two first electric telescopic rods 14 set at the bottom of the support rod body 13, together with the support plate 15 fixed at the bottom, can extend the first electric telescopic rods 14 when leg training is required, and stop the first electric telescopic rods 14 without using them. The first electric telescopic rods 14 can be used as a fixed frame, and when the movable frame structure is used, the first electric telescopic rods 14 retract.
[0042] Furthermore, the transmission rod structure includes a first mounting block 10 and a second mounting block 9 fixed to the top of the movable plate 8, with the first mounting block 10 and the second mounting block 9 distributed internally and externally; and a first transmission rod 11 and a second transmission rod 12 respectively rotatably connected to the first mounting block 10 and the second mounting block 9 via a first pin, with the two sets of transmission rod structures located on the first transmission rod 11 being centrally symmetrically distributed; it also includes a third transmission rod 18 rotatably connected to the second transmission rod 12 via a second pin away from the end of the second mounting block 9, with the middle of the second transmission rod 12 and the third transmission rod 18 connected; the two ends of the third transmission rod 18 are respectively rotatably connected to the ends of the first transmission rod 11 and the support rod body 13 via a third pin; it also includes a drive mechanism disposed between the two sets of slide block assemblies for driving the two first transmission rods 11 to rotate.
[0043] As shown in Figures 1, 5, and 6, since one end of the third transmission rod 18 is rotatably connected to the support rod body 13, and the other end is rotatably connected to the first transmission rod 11, and the middle part is rotatably connected to the second transmission rod 12, when the first transmission rod 11 rotates, the second transmission rod 12, the support rod body 13, and the third transmission rod 18 will deflect accordingly. The support rod body 13 can move horizontally and vertically through the limiting frame 19, thereby completing the gait simulation process.
[0044] Furthermore, the drive mechanism includes a mounting base 24 fixed to the bottom of one of the movable plates 8, a servo motor 25 mounted on the mounting base 24, and a first transmission wheel 27 fixed to the output end of the servo motor 25; and a drive rod 23 rotatably connected to the opposite sides of the two first mounting blocks 10, with both ends of the drive rod 23 passing through the first mounting blocks 10 and fixedly connected to the first transmission rod 11; it also includes second transmission wheels 26 fixed to both ends of the drive rod 23, and a transmission belt 28 is sleeved between the second transmission wheel 26 near the servo motor 25 and the first transmission wheel 27. When the servo motor 25 is running, it can drive the drive rod 23 to rotate, thereby causing the first transmission rod 11 to rotate.
[0045] Since the two ends of the drive rod 23 pass through the first mounting block 10 and are fixedly connected to the first transmission rod 11, and the two first transmission rods 11 are centrally symmetrically distributed as shown in Figure 1, the two support rod structures on one side move forward alternately, while the oblique support rod structures distributed in front and behind move forward synchronously to realize the process of moving forward and backward. The support rod structure can also move vertically and horizontally, which can simulate the actions of stepping, supporting, and lifting backward, and further realize the gait simulation process.
[0046] In addition, a transmission belt 28 is sleeved between the second transmission wheel 26 fixed at the end of the drive rod 23 and the first transmission wheel 27 fixed at the output end of the servo motor 25, as shown in Figure 6. Therefore, the gait simulation mechanism can be made to run by the power provided by the servo motor 25.
[0047] Example 3

It also includes a support pad 29 fixed to the upper part of the support shaft 41, and the support pad 29 is used to support the patient's groin. It further includes two connecting members 38, each with a connecting shaft at its upper and lower outer ends, and two sets of support bars 34 rotatably connected to the two sets of connecting shafts. The end of the support bar 34 at the upper end of the connecting member 38 away from it is rotatably connected to the mounting shaft on the mounting member 32. The end of the support bar 34 at the lower end of the connecting member 38 away from it passes through… The system includes a connecting rod 40; a first support plate 37 and a second support plate 39 fixed to the front of the two sets of support bars 34, with the first support plate 37 and the second support plate 39 distributed vertically and used to support the patient's thigh and calf respectively; a meshing transmission assembly disposed between the two sets of support bars 34 for adjusting the deflection angle of the first support plate 37 and the second support plate 39; a second motor 33 disposed on the side of the mounting member 32 away from the support bar 34, with the output shaft of the second motor 33 passing through the mounting member 32 and fixed to the support bar 34 to provide power for the rotation of the upper support bar 34; and a first motor 31 disposed on the outer wall of the connecting block 30 to provide power for the rotation of the support shaft 41.
[0049] In this embodiment, the second motor 33 and the first motor 31 are preferably ordinary DC geared motors, which are driven when powered on and rotate freely when powered off, as shown in Figures 7-10. The support pad 29 fixed to the upper part of the support shaft 41 provides auxiliary support to the patient's leg root. The first support plate 37 and the second support plate 39 fixed to the two upper and lower support bars 34 respectively provide auxiliary support to the patient's thigh and calf. The two support bars 34 are connected by a connector 38. The upper support bar 34 is rotatably connected to the mounting piece 32 at the bottom of the support shaft 41, and a connecting rod 40 is connected between the bottom ends of the lower support bars 34. The meshing transmission assembly between the strips 34 can adjust the rotation angle of the first support plate 37 and the second support plate 39, thereby adjusting the range of motion of the patient's knee. In conjunction with the support pad 29, it can realize rehabilitation training of hip and knee extension and flexion, and walk training in conjunction with the gait simulation mechanism. This design can provide auxiliary support for the patient's hip, thigh and calf through the set support pad 29, the first support plate 37 and the second support plate 39. Furthermore, through the rotatable support pad 29 and the set meshing transmission assembly, the angle of the patient's hip and knee can be adjusted, further conducting active and passive training of leg range of motion and walking. This design has a simple structure and high flexibility.
[0050] Furthermore, the meshing transmission assembly includes two incomplete gears 36, which are respectively fixed on the upper and lower distributed front support bars 34, and the two incomplete gears 36 mesh.
[0051] Since the two incomplete gears 36 are fixed on the two support bars 34 distributed above and below, as shown in Figure 10, and the two incomplete gears 36 are placed on the two support bars 34 on the front side, through the meshing of the incomplete gears 36, when the upper support bar 34 deflects, the lower support bar 34 moves in the opposite direction to realize the knee extension and knee flexion movements.
[0052] Furthermore, the first support plate 37 and the second support plate 39 are respectively provided with hook and loop fasteners 35 for limiting and fixing the patient's legs.
