[0034] Referring to Figures 1 to 5 , the embodiment of the present utility model provides a wheelchair for Parkinson's patients, which includes a seat board 120 and a support frame 110, and further includes a backrest adjustment assembly 200 and a sitting posture adjustment assembly 300.

[0035] The backrest adjustment assembly 200 includes a backrest plate 210, a first rotating shaft 220, and a connecting bracket 230. The first rotating shafts 220 are provided on both sides of the seat plate 120. Connecting brackets 230 are provided at both ends of the backrest plate 210. The connecting brackets 230 are rotationally engaged with the first rotating shafts 220 so that the angle between the backrest plate 210 and the seat plate 120 can be adjusted. The backrest adjustment assembly 200 is used to adjust the angle between the patient's body and legs; the sitting posture adjustment assembly 300 includes a connecting arm 310, a second rotating shaft 320, and a footrest 330. One end of the connecting arm is connected to the seat plate 120, and the other end is connected to the second rotating shaft 320. The second rotating shaft 320 is rotationally engaged with the footrest 330.

[0036] It should be noted that the first rotating shafts 220 are symmetrically arranged on both sides of the seat plate 120. The connecting brackets 230 are rotationally engaged with the first rotating shafts 220, and the backrest plate 210 is connected to the connecting brackets 230 so that when the connecting brackets 230 rotate, the backrest plate 210 can rotate accordingly, thereby adjusting the angle between the backrest and the seat plate 120. Furthermore, when a Parkinson's patient sits on the seat plate 120, with the spine leaning against the backrest plate 210, the angle between the backrest and the seat plate 120 can be adjusted to find a suitable sitting posture to relieve the patient's fatigue.

[0037] In addition, the sitting posture adjustment assembly 300 is used for the patient to place the feet and legs. The front end of the connecting arm 310 is connected to the bottom end of the seat plate 120, and the rear end bends downward. The second rotating shaft 320 is provided inside the connecting arm 310. The second rotating shaft 320 is rotationally engaged with the footrest 330 so that the footrest 330 can rotate around the second rotating shaft 320. This rotation mode can drive the patient's ankles to rotate back and forth. The reason is that the feet of most Parkinson's patients will tremble to varying degrees. The rotation of the footrest 330 around the second rotating shaft 320 can make the patient's feet always fit with the soles of the feet, and the footrest 330 can also enable the patient's ankles to move moderately to ensure their flexibility, which helps with recovery.

[0038] As an example, the front end of the connecting arm 310 is arranged along the length direction of the seat plate 120, and the connecting arm 310 is fixed to the bottom of the seat plate 120. In some other embodiments, the front end of the connecting arm 310 is slidably engaged with the seat plate 120 to adjust the distance between the footrest 330 and the seat plate 120, so as to adapt to patients of different body types to sit on the seat plate 120 in a comfortable sitting posture.

[0039] According to the wheelchair for Parkinson's patients provided by the embodiments of the present utility model, the backrest adjustment assembly 200 includes a first sliding block 240, a second sliding block 250, an extension rod 260, and a support rod 270. The extension rod 260 is vertically disposed on the seat board 120. A chute 211 is formed on the backrest board 210. The first sliding block 240 is slidably disposed in the chute 211. The second sliding block 250 is slidably disposed on the extension rod 260. One end of the support rod 270 is rotatably connected to the first sliding block 240, and the other end is rotatably connected to the second sliding block 250.

[0040] It should be noted that the first sliding block 240 slides in the chute 211. The second sliding block 250 is sleeved outside the extension rod 260, and the second sliding block 250 is slidably engaged with the extension rod 260. A support rod 270 is disposed between the second sliding block 250 and the first sliding block 240, and the support rod 270 is rotatably connected to both the first sliding block 240 and the second sliding block 250.

[0041] As an example, the length of the support rod 270 remains unchanged. Therefore, when the first sliding block 240 slides, it can drive the corresponding sliding of the second sliding block 250 to change the angle between the backrest board 210 and the seat board 120, so that the patient can adjust his own sitting posture. The support rod 270 can also support the backrest board 210, thereby supporting the patient's back, so that the backrest adjustment assembly 200 can have sufficient stability and sufficient adjustment space at the same time.

[0042] It should be noted that in some other embodiments, the support rod 270 can be an electric telescopic rod. If the length of the support rod 270 can be changed, when one of the first sliding block 240 and the second sliding block 250 slides, it will not drive the other to slide. If the second sliding block 250 and the first sliding block 240 slide simultaneously, the length of the support rod 270 will increase or decrease accordingly. Such an embodiment can also maintain the normal operation of the backrest adjustment assembly 200.

[0043] According to the wheelchair for Parkinson's patients provided by the embodiments of the present utility model, the backrest adjustment assembly 200 includes a driving member 280 and a threaded rod 290.

The threaded rod 290 is rotatably engaged with the wall surface of the chute 211, and the first sliding block 240 is rotatably and slidably engaged with the threaded rod 290.

[0044] The threaded rod 290 is rotationally fitted with the wall surface of the sliding groove 211. After the driving member 280 is turned on, the driving member 280 can drive the threaded rod 290 to rotate. The first sliding block 240 is rotationally and slidably fitted with the threaded rod 290, so that the first sliding block 240 can slide bidirectionally along the threaded rod 290. After adjusting to a suitable angle, the driving member 280 can be turned off, and thus the adjustment method of the angle between the backrest plate 210 and the seat plate 120 can be convenient and fast.

[0045] According to the wheelchair for Parkinson's patients provided by the embodiment of the present invention, the backrest adjustment assembly 200 includes a plug pin 251. A stable groove 261 is formed on the extension rod 260.

[0046] It should be understood that a stable groove 261 is formed on the extension rod 260, and the plug pin 251 can penetrate through the side of the second sliding block 250 that cooperates with the stable groove 261. When the plug pin 251 is inserted tightly against the bottom wall of the stable groove 261, the second sliding block 250 can be fixed on the extension rod 260. When the plug pin 251 is pulled out, the second sliding block 250 can slide on the extension rod 260. Therefore, the plug pin 251 and the stable groove 261 are used in cooperation to limit and fix the second sliding block 250, avoid safety accidents during use, and at the same time make the support of the backrest plate 210 on the patient's back stable and strong.

[0047] According to the wheelchair for Parkinson's patients provided by the embodiment of the present invention, the sitting posture adjustment assembly 300 includes a seat cushion 340, a lumbar cushion 350, and a headrest 360.
