DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 A wheelchair with adjustable sitting posture for orthopedic rehabilitation includes a wheelchair frame 1, wheels 12 are rotatably connected to the left and right sides of the wheelchair frame 1, a cushion 5 is fixedly connected to the top of the wheelchair frame 1, a support leg 4 is fixedly connected to the front side of the bottom of the wheelchair frame 1, a pulley 2 is installed at the bottom of the support leg 4, and a foot support mechanism 3 is sleeved on the surface of the support leg 4.

[0024] Furthermore, a connecting cloth 6 is connected to the rear side of the seat cushion 5, a backrest 8 is connected to the top of the connecting cloth 6, a silicone pad 7 is fixedly installed on the front of the backrest 8, the front side of the silicone pad 7 is arc-shaped, and support plates 14 are fixedly connected to the left and right sides of the rear side of the wheelchair frame 1, a rotating part 17 fixed to the rear side of the backrest 8 is rotatably connected inside the support plate 14, a connecting part 18 is fixedly connected to the rear side of the backrest 8, an electric telescopic rod 16 is rotatably connected to the top of the connecting part 18, and a fixing frame 15 is rotatably connected to the bottom of the electric telescopic rod 16, and the fixing frame 15 is fixedly connected to the support plate 14.

[0025] Furthermore, a hand wheel 11 is fixedly connected to a side of the wheel 12 away from the wheelchair frame 1 .

[0026] Furthermore, armrests 10 and push handles 9 are fixedly connected to the left and right sides of the top of the wheelchair frame 1.

[0027] The user sits on the seat cushion 5 and leans on the backrest 8. The backrest 8 supports the patient's back. The silicone pad 7 arranged on the backrest 8 can increase the comfort of the user's back. The medical staff can push the wheelchair frame 1 to move by the push handle 9 to help the patient move. During the movement of the wheelchair frame 1, the wheels 12 and the pulley 2 roll on the ground. The patient can also rotate the wheels 12 by the handwheel 11 to achieve movement on the ground. The patient's hands can be placed on the armrests 10 to avoid the arms being suspended in the air.

[0028] By providing a backrest 8 with an adjustable angle, the most comfortable posture can be found according to personal needs and current activity status. Changing the sitting posture can avoid the concentration of bone and muscle pressure caused by a single posture for a long time, reduce pain and discomfort, especially the pressure on the spine and buttocks, and by adjusting the angle of the backrest 8, the user can maintain the best participation in different scenarios. For example, the user can sit upright when performing desktop activities, and can choose a more relaxed tilted position when resting or moving long distances.

[0029] When the angle of the backrest 8 needs to be adjusted, the electric telescopic rod 16 is controlled by the controller 20. During the extension and retraction of the electric telescopic rod 16, the fixed frame 15 and the support plate 14 support the bottom of the electric telescopic rod 16. The piston rod of the electric telescopic rod 16 drives the connecting member 18 to move, and the connecting member 18 drives the backrest 8 and the rotating member 17 to rotate. The rotating member 17 rotates inside the support plate 14, thereby realizing the adjustment of the angle of the backrest 8. During the adjustment of the backrest 8, the connecting cloth 6 connected to its bottom is driven to bend synchronously, thereby realizing a flexible connection between the seat cushion 5 and the backrest 8.

[0030] Furthermore, a battery 19 is fixedly mounted on the bottom of the wheelchair frame 1 , and a controller 20 is fixedly mounted on the surface of the battery 19 .

[0031] The storage battery 19 supplies power to the electrical equipment, and the controller 20 controls the electrical equipment.

[0032] Furthermore, the foot support mechanism 3 includes an adjustment sleeve 304 sleeved on the surface of the leg 4, a mounting hole 303 adapted to the diameter of the leg 4 is opened inside the adjustment sleeve 304, a manual bolt 302 is installed on the adjustment sleeve 304, and a plurality of threaded holes 13 threadedly connected to the manual bolt 302 are opened on the leg 4.

[0033] Furthermore, the surface of the adjustment sleeve 304 is fixedly connected to the rotating frame 301, and the rotating frame 301 is movably connected inside with a limiting bolt 307. The surface of the limiting bolt 307 is sleeved with an adjusting piece 306, and the top of the adjusting piece 306 is provided with a nut 308. The nut 308 is threadedly sleeved on the surface of the limiting bolt 307 to limit the adjusting piece 306, and the top of the adjusting piece 306 is fixedly connected with a pedal 305.

[0034] Furthermore, a sliding groove 309 movably connected to the limiting bolt 307 is provided on the rotating frame 301 .

[0035] By providing the foot support mechanism 3, it is possible to facilitate the placement of the patient's feet, and the foot support mechanism 3 can be adjusted on the support legs 4 to adapt to the differences between different patients, ensuring that the feet receive the most appropriate support and avoiding discomfort or injury caused by excessive extension or compression. Correct foot alignment is essential for maintaining the normal position of the bone structure, especially during the healing period of fractures. By adjusting the height of the foot support mechanism 3, blood circulation in the lower limbs can be promoted, the risk of swelling and deep vein thrombosis can be reduced, and the discomfort caused by suspended or compressed feet can be reduced, allowing patients to sit in the wheelchair longer without feeling tired, thereby improving the comfort of use.

[0036] When it is necessary to adjust the height of the foot support mechanism 3, the adjustment sleeve 304 is slid on the surface of the leg 4 through the mounting hole 303 to change the use height of the adjustment sleeve 304, thereby driving the height of the footrest 305 to change. After the adjustment is completed, the manual bolt 302 is screwed into the threaded hole 13 on the leg 4 to fix the adjustment sleeve 304 and the rotating frame 301. When it is necessary to adjust the extension length of the footrest 305, the nut 308 is screwed out of the surface of the limit bolt 307 to change the position of the limit bolt 307 inside the slide groove 309. When the slide groove 309 and the footrest 305 are adjusted to the appropriate position, the nut 308 is reset. The nut 308 and the limit bolt 307 clamp the adjustment member 306 on the top of the rotating frame 301, thereby fixing the adjustment member 306 and the footrest 305.

[0037] When the foot support mechanism 3 is not needed, the manual bolt 302 is unscrewed out of the threaded hole 13, and the adjustment sleeve 304 is rotated inward ninety degrees on the surface of the leg 4, so as to retract the two foot support mechanisms 3. After the retraction is completed, the manual bolt 302 is screwed into the threaded hole 13 on the front side to fix the adjustment sleeve 304. The threaded hole 13 is located on the front side and the left and right sides of the surface of the leg 4.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
