[0048] Specifically, after the first positioning bolt 34 and the second positioning bolt 35 are respectively separated from the limiting holes in the positioning plate 23, the elastic backrest cover 5 is first pushed to make the two groups of armrest rods 31 rotate around the positioning pin 22, and the rotated elastic backrest cover 5 is fitted and connected to the top of the elastic seat cushion cover 4, and then the roller bracket 21 is pushed to make the roller body 25 rotate around the positioning pin 22, so as to fold the two groups of roller bodies 25 close to the universal self-locking wheel 14, completing the first step of folding and storage, and then the right-angled circular tube 11 or the two groups of curved handrails 63 are squeezed against each other to make the two groups of right-angled circular tubes 11, the roller bracket 21 and the handrail 31 close to each other, for the second step of folding and storage, by lifting the telescopic rod 61 or placing the two groups of curved handrails 63 at the level of the shoulders, for convenient operation after the wheelchair is folded and stored;

[0049] During the horizontal movement of the two groups of right-angled circular tubes 11, the guide rods 12 are driven, so that the guide rods 12 are slidably connected to different positions of the inner wall of the sleeve arm 17, so as to adjust the seat size according to the different buttocks of the user.

[0051] When the patient steps on the footrest 15, a leg exercise simulating "riding" is performed to relieve the blockage of blood circulation in the legs caused by long-term sitting in a wheelchair. In the process of reciprocating stepping on the footrests 15 on both sides, the linkage rod 16, the driving bevel gear 712, the driven bevel gear 710, the positioning rod 79, the driving gear 78 and the rack belt 71 are driven to transmit synchronously, so that the driven gear 72 moves back and forth between the two sets of driving gears 78, which is used to synchronously drive the multiple groups of first massage balls 75 to move in the elastic seat cushion cover 4 and the multiple groups of second massage balls 77 to move in the elastic backrest cover 5. In the process of continuous operation of the first motor 74 and the second motor 76, the multiple groups of first massage balls 75 and the second massage balls 77 rotate in a reciprocating state, which is used to relieve the local muscle pressure of the user sitting on the elastic seat cushion cover 4 or leaning on the elastic backrest cover 5. The continuous operation of the micro motors on the top of the two sets of positioning rods 79 can also be used to drive the driving gear 78 to rotate, forming a dual-drive mode to meet the dual-drive mode of intelligent electric and manual operation of the wheelchair user.

[0052] The working principle of the intelligent diagnosis and treatment convenient wheelchair proposed in the embodiment of the present invention is as follows:

[0053] Through the interactive touch screen 8, the patient conducts a video diagnosis and treatment with the online doctor. The patient steps on the pedal 15 according to the online doctor's instructions. The cadence meter detects the patient's pedaling frequency within a time range and diagnoses the flexibility of the knee joint. If the patient's knee joint flexibility is limited and the pedaling frequency is not reached, the electric heating belt 117 performs local heating treatment on the patient's knee joint.

[0054] After the first positioning bolt 34 and the second positioning bolt 35 are separated from the limiting holes in the positioning plate 23 respectively, the elastic backrest cover 5 is first pushed to make the two groups of armrest rods 31 rotate around the positioning pin 22, and the rotated elastic backrest cover 5 is fitted and connected to the top of the elastic seat cushion cover 4, and then the roller bracket 21 is pushed to make the roller body 25 rotate around the positioning pin 22, so as to fold the two groups of roller bodies 25 close to the universal self-locking wheel 14, completing the first step of folding and storage, and then the right-angled circular tube 11 or the two groups of curved handrails 63 are squeezed against each other to make the two groups of right-angled circular tubes 11, the roller bracket 21 and the handrail 31 close to each other, for the second step of folding and storage, by lifting the telescopic rod 61 or placing the two groups of curved handrails 63 at the level of the shoulders, for convenient operation after the wheelchair is folded and stored;

[0055] The guide rods 12 are driven by the horizontal movement of the two groups of right-angled circular tubes 11, so that the guide rods 12 are slidably connected to different positions of the inner wall of the sleeve arm 17, so as to adjust the seat size according to the different buttocks of the user. The adjusted seat utilizes the scalability and wrapping characteristics of the elastic seat cushion cover 4, so that the elastic seat cushion cover 4 can be compatible with the adjusted spacing between the right-angled circular tubes 11 and the sleeve arm 17. When the user sits on top of the elastic seat cushion cover 4, the two ends of the elastic seat cushion cover 4 adaptively pull the right-angled circular tubes 11 on both sides close to the user's buttocks, thereby improving the safety and comfort of the user in the wheelchair;

[0056] After the first positioning bolt 34 is separated from the limiting hole in the positioning plate 23, the roller bracket 21 can be rotated clockwise or counterclockwise. During the process of the roller bracket 21 rotating around the positioning pin 22, the first positioning hole 24 is matched with the limiting holes at different positions in the positioning plate 23, so that the roller bracket 21 after the angle adjustment drives the roller body 25, so as to adjust the roller body 25 to different positions on both sides of the user, so that users with different heights and arm lengths can push the roller body 25 for use;

[0057] When the patient steps on the foot pedals 15, a leg exercise simulating "riding" is performed to relieve the blockage of blood circulation in the legs caused by long-term sitting in a wheelchair. In the process of reciprocating stepping on the foot pedals 15 on both sides, the linkage rod 16, the driving bevel gear 712, the driven bevel gear 710, the positioning rod 79, the driving gear 78 and the rack belt 71 are driven to transmit synchronously, so that the driven gear 72 moves back and forth between the two sets of driving gears 78, which is used to synchronously drive the multiple groups of first massage balls 75 to move in the elastic seat cushion cover 4 and the multiple groups of second massage balls 77 to move in the elastic backrest cover 5. In the process of continuous operation of the first motor 74 and the second motor 76, the multiple groups of first massage balls 75 and the second massage balls 77 rotate in a reciprocating state, which is used to relieve the local muscle pressure of the user sitting on the elastic seat cushion cover 4 or leaning on the elastic backrest cover 5. The continuous operation of the micro motors on the top of the two sets of positioning rods 79 can also be used to drive the driving gear 78 to rotate, forming a dual-drive mode to meet the needs of the wheelchair user's intelligent electric and manual dual-drive modes.
