[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-6The leg rehabilitation assistive exercise equipment includes: a flat lying platform 1 and two U-shaped supports 2 fixedly installed at the bottom of the flat lying platform 1. Two casters are fixedly installed at the bottom of each U-shaped support 2 to facilitate movement of the flat lying platform 1. An opening 3 is provided on the flat lying platform 1. A common support plate 4 is provided between the two U-shaped supports 2, and multiple lifting screws 5 are rotatably mounted on the top of the plate. Rectangular frame sleeves 6 are threaded onto each of the lifting screws 5. Concave connecting seats 7 are fixedly installed on the top of each of the rectangular frame sleeves 6, and the tops of the concave connecting seats 7 extend to the opening. The inner wall of the movable opening 3 is movably connected to the inner wall of the movable opening 3, and a contact roller 8 is rotatably installed in each concave connecting seat 7. The top of the multiple contact rollers 8 is tangent to the top end face of the flat platform 1. Multiple massage heads 9 are embedded in the multiple contact rollers 8. The massage heads 9 can form a squeezing massage effect on the patient's calf area. In addition, multiple third servo motors are fixedly installed at the bottom of the support plate 4. The output shafts of the multiple third servo motors are respectively fixedly connected to the bottom ends of multiple lifting screws 5. By controlling the third servo motors to rotate forward or backward, an upward massage effect can be formed on the patient's legs. During the rehabilitation exercise process involving raising or lowering the load, a connecting frame 10 is fixedly installed at the bottom of the support plate 4, and a support box 13 is provided below the connecting frame 10. Two toothed posts 14 are fixedly installed at the bottom of the connecting frame 10. The bottom of each toothed post 14 extends into the support box 13 and is movably connected to the top of the support box 13. Two first connecting shafts 15 are rotatably installed inside the support box 13. Lifting gears 16 are fixedly sleeved on each of the two first connecting shafts 15. The two lifting gears 16 mesh with the two toothed posts 14 respectively. In addition, on one side of the support box 13... A second servo motor is fixedly installed on the outer side wall. Its output shaft is fixedly connected to one end of one of the first connecting shafts 15. Both first connecting shafts 15 are fitted with synchronous pulleys, and the same synchronous belt is fitted on the two synchronous pulleys. By starting the second servo motor, the toothed column 14 can lift the support plate 4, and then the patient's legs can be slightly lifted by multiple contact rollers 8. A reciprocating pulling mechanism is provided under the flat platform 1 to drive the support box 13 to move back and forth horizontally. In this way, the patient's legs can be massaged and rehabilitated horizontally.

[0024] The reciprocating pulling mechanism mentioned above includes a backrest plate 18, which is fixedly installed at the bottom of the flat platform 1. A second connecting shaft 19 is rotatably installed on the backrest plate 18. A disc 20 is fixedly sleeved on the second connecting shaft 19. A pull rod 17 is fixedly installed on the outer wall of the bearing box 13 near the disc 20. A hinge arm 22 is hinged to the pull rod 17 away from the bearing box 13. An eccentric shaft 21 is fixedly installed on the disc 20. The eccentric shaft 21 passes through the hinge arm 22 and is rotatably connected to the hinge arm 22. A first servo motor is fixedly installed on one side of the backrest plate 18, and its output shaft is fixedly connected to one end of the second connecting shaft 19.

[0025] In this method, in order to provide a supporting sliding effect for the carrier box 13 and ensure its linear horizontal movement, the same supporting slide rail 11 is fixedly installed on the side of the two U-shaped brackets 2 that are close to each other. The supporting slide rail 11 is located below the carrier box 13, and two connecting sliders 12 are slidably installed on the supporting slide rail 11. The tops of the two connecting sliders 12 are fixedly connected to the carrier box 13.

[0026] In this method, in order to ensure that the rectangular frame sleeve 6 can only move in a straight line, a limit frame is fixedly installed on the top of the bearing plate 4. Multiple rectangular frame sleeves 6 pass through the top of the limit frame and are slidably connected to the top of the limit frame. A stop protrusion is fixedly installed at the bottom of each rectangular frame sleeve 6 to prevent the rectangular frame sleeve 6 from separating from the limit frame.

[0027] The working principle of the leg rehabilitation assistive exercise device provided by this utility model is as follows:

[0028] When rehabilitation exercises are needed for a patient's injured leg, the patient is first laid on the flat platform 1. Then, the lifting position is determined according to the length of the patient's leg. After determining the lifting position, the corresponding contact roller 8 is selected, and the corresponding third servo motor is started in the forward direction. Its output shaft drives the corresponding lifting screw 5 to rotate. At this time, through the threaded engagement between the lifting screw 5 and the rectangular frame sleeve 6, the corresponding rectangular frame sleeve 6 carries the corresponding contact roller 8 to rise. During the process of the contact roller 8 rising, the patient's leg will be gradually lifted by the contact roller 8. After being lifted to a certain height, the third servo motor is started in the reverse direction to lower the patient's leg. Then, the third servo motor is started in the forward direction again to lift the patient's leg again. Then, the third servo motor is started in the reverse direction again, and so on, thereby realizing the reciprocating lifting and lowering of the patient's leg, and thus realizing the lifting rehabilitation exercise.

[0029] In the later stages of rehabilitation, when massage is needed on the patient's legs, the second servo motor is started first, its output shaft drives the corresponding first connecting shaft 15 to rotate. Simultaneously, under the transmission of the synchronous pulley and synchronous belt, the two first connecting shafts 15 rotate synchronously, causing the two lifting gears 16 to rotate together. During rotation, through the meshing between the lifting gears 16 and the toothed column 14, the two toothed columns 14 rise against the connecting frame 10, causing multiple contact rollers 8 to rise together until the toothed column 14 rises to the highest position. At this point, the patient's leg is slightly lifted. Then, the first servo motor is started, its output shaft drives the second connecting shaft 19 to rotate. Through the rotation of the eccentric shaft 21 on it, and with the connection of the hinge arm 22, the pull rod 17 moves the carrier box 13 in a reciprocating horizontal motion. In this way, the massage head 9 can be used to massage the patient's calf area while moving, thereby promoting blood circulation and achieving a good rehabilitation effect.

[0030] Compared with related technologies, the leg rehabilitation assistive exercise device provided by this utility model has the following beneficial effects:

[0031] This utility model provides a leg rehabilitation auxiliary exercise device. Through the set lifting screw 5 and rectangular frame sleeve 6, the contact roller 8 can be raised or lowered, thereby enabling the patient's leg to be lifted for rehabilitation exercises. Furthermore, the setting of multiple contact rollers 8 allows people to select and use them according to the length of the patient's legs, improving the flexibility of use. In addition, through the cooperation between the lifting gear 16 and the toothed column 14, the patient's leg can be slightly lifted by multiple contact rollers 8. Then, by rotating the disc 20, a moving massage rehabilitation work can be achieved for the patient's calf, so as to realize a variety of rehabilitation exercise methods.
