[0002] After a stroke, many patients suffer from varying degrees of limb dysfunction, with walking impairment being a significant proportion. Walking is one of the most basic daily activities and a function that patients most urgently hope to regain. A walking aid is an assistive device that helps the body support weight, maintain balance, and walk. A suitable walking aid can help those with limited leg mobility or who have lost the ability to walk regain some walking ability, and even go for walks like normal people. Common walking aids include walking canes, frame walkers, wheelchairs, and orthotics.

[0003] For example, the adjustable rehabilitation walking aid disclosed in the authorization announcement number CN214550186U includes a fixed base, an adjustable extension seat is movably installed on the right side of the fixed base, an adjustment plate corresponding to the adjustable extension seat is movably installed on the top of the fixed base, universal rollers are fixedly installed at the bottom of both the fixed base and the adjustable extension seat, and a brake pad is movably installed on one side of the universal roller at the bottom of the fixed base.

[0024] A fourth electric push rod 27 is movably installed on the outer wall of the walking frame 26 below the main arm 29. The fourth electric push rod 27 plays the role of power drive. A sixth shaft 30 is provided at the top of the fourth electric push rod 27, and the fourth electric push rod 27 is movably connected to the main arm 29 through the sixth shaft 30.

[0025] The top of the walking frame 26 on one side of the main arm 29 is movably mounted with a second electric push rod 7. The second electric push rod 7 plays the role of power drive. The top of the second electric push rod 7 is mounted with an eighth shaft 23. The second electric push rod 7 is movably connected to the support cylinder 33 through the eighth shaft 23. The inner wall of the support cylinder 33 is mounted with a handrail 32, and the handrail 32 is fixedly connected to the support cylinder 33.

[0026] With the patient seated on the surface of the rotating disc 8, the front wheels 25 and rear wheels 24 facilitate movement. When the patient needs to stand, the curved belt 35 is placed on the patient's back, and the patient grips the handrails 32 with both hands. The control panel 9 is then activated to open the second electric push rod 7. With the support of the walking frame 26, the second electric push rod 7 drives the support cylinder 33 via the eighth axis 23 to rotate around the seventh axis 31, thereby driving the telescopic rod 34, the curved belt 35, and the patient to move. The control panel 9 is then activated to open the fourth electric push rod 27, and the walking frame 26... The main arm 29 is supported by the fifth axis 28.

[0028] A leg guard 14 is provided on the side wall of the wheelchair 1 near the walking frame 26. A third shaft 13 is provided at the top of the leg guard 14, and the leg guard 14 is movably connected to the wheelchair 1 through the third shaft 13. A third electric push rod 22 is movably installed inside the wheelchair 1 on the side of the leg guard 14. The third electric push rod 22 plays a power driving role. A fourth shaft 15 is provided at the top of the third electric push rod 22, and the third electric push rod 22 is movably connected to the leg guard 14 through the fourth shaft 15.

[0029] When the patient is sitting on the surface of the rotating disc 8, and when the patient needs to lie supine, the control panel 9 opens the first electric lever 3. The first electric lever 3 drives the backrest 2 to rotate around the first axis 4 via the second axis 6, so that the backrest 2 can be tilted to make it easier for the patient to lie supine. The control panel 9 opens the third electric push rod 22. The third electric push rod 22 drives the leg guard 14 to rotate around the third axis 13 via the fourth axis 15, so that the leg guard 14 can support the patient's legs. This realizes the convenient support of the rehabilitation patient walking aid for the patient to use when lying supine, facilitates the adjustable support of the patient's legs when lying supine, and improves the patient's comfort when lying supine.

[0030] A rotating box 20 is installed inside the wheelchair 1 below the rotating disk 8. A rotating column 19 is set at the center of the rotating box 20 and is fixedly connected to the rotating disk 8. Ball bearings 21 are symmetrically installed on the top of the rotating box 20 on one side of the rotating column 19 and are slidably connected to the rotating disk 8.

[0031] A worm gear 18 is installed at the bottom of the rotating column 19. A worm 17 is installed inside the rotating box 20 on one side of the worm gear 18. A servo motor 16 is installed inside the rotating box 20 on one side of the worm 17. The output end of the servo motor 16 is connected to the worm 17. The servo motor 16 plays the role of power transmission. A control panel 9 is installed on the outer wall of the walking frame 26. The output end of the control panel 9 is electrically connected to the input end of the fourth electric push rod 27, the second electric push rod 7, the third electric push rod 22, the servo motor 16, and the first electric rod 3. Rear wheels 24 are symmetrically installed at the bottom of the wheelchair 1. Front wheels 25 are symmetrically installed at the bottom of the walking frame 26. A guardrail 5 is symmetrically set at the top of the wheelchair 1. A sliding rod 11 is symmetrically installed at the bottom of each guardrail 5. A sliding sleeve 10 is slidably installed at the bottom of each sliding rod 11. A locking bolt 12 is installed on the outer wall of each sliding sleeve 10. The locking bolt 12 extends to the surface of the sliding rod 11.

[0032] By pressing the barrier 5, the barrier 5 moves the slide rod 11, which then enters the sliding sleeve 10. The locking bolt 12 fixes the slide rod 11 and the sliding sleeve 10, thus lowering the height of the barrier 5. The control panel 9 turns on the servo motor 16, which drives the worm gear 17 to rotate. Under the meshing action of the worm gear 17 and the worm wheel 18, the worm wheel 18 rotates. Supported by the rotating box 20, the worm wheel 18 drives the rotating column 19 to rotate, which in turn drives the rotating disk 8 to rotate. The rotating disk 8 then rotates the patient, facilitating the adjustment of the patient's position. This allows for convenient adjustment of the patient's position in the rehabilitation department, making it easier for patients to get on and off the equipment.

[0033] In this embodiment, the patient first sits on the surface of the rotating disc 8, and is easily moved by the cooperation of the front wheel 25 and the rear wheel 24. When the patient needs to stand, the arc-shaped belt 35 is placed on the patient's back, and the patient grips the handrail 32 with both hands. The second electric push rod 7 drives the support cylinder 33 to rotate around the seventh axis 31 via the eighth axis 23, thereby driving the telescopic rod 34, the arc-shaped belt 35, and the patient to move. The fourth electric push rod 27 drives the main arm 29 to rotate around the fifth axis 28 via the sixth axis 30. Under the control of the second electric push rod 7 and the fourth electric push rod 27, and with the assistance of the patient's hands, the patient can stand and walk more easily, thus reducing the workload of caregivers. When the patient needs to lie down, the first electric rod 3 is driven by the second axis 6. The backrest 2 rotates around the first axis 4 to allow the backrest 2 to tilt to a more comfortable supine position for the patient. The third electric push rod 22 drives the leg guard 14 to rotate around the third axis 13 via the fourth axis 15, allowing the leg guard 14 to support the patient's legs. By pressing the guardrail 5, the guardrail 5 moves the sliding rod 11, which enters the sliding sleeve 10. The locking bolt 12 fixes the sliding rod 11 and the sliding sleeve 10, thus lowering the height of the guardrail 5. The servo motor 16 drives the worm gear 17 to rotate, and the worm gear 17 and worm wheel 18 mesh to drive the worm wheel 18 to rotate. The worm wheel 18 drives the rotating column 19 to rotate, which in turn drives the rotating disk 8 to rotate. The rotating disk 8 then rotates the patient, allowing for easy adjustment of the patient's position to complete the use of the walking aid.
