DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 As shown, a rehabilitation walking-aid wheelchair includes a frame 1, a backrest 2 is fixedly connected to the rear portion of the upper end of the frame 1, a seat cushion 3 is rotatably connected to the inner surface of the backrest 2, universal wheels 4 are symmetrically fixedly installed on the left and right ends of the frame 1, active and passive components 5 are commonly provided on the inner surface of the backrest 2, the rear end of the backrest 2 and the left and right ends of the frame 1, and a ventilation and massage component 6 is commonly provided on the inner cavity and the lower end of the seat cushion 3.

[0033] During the implementation of this embodiment, the user can perform active or passive exercises on his legs or hands through the active and passive components 5, and can use the wheelchair as a walking aid. When the user is exercising his legs or hands, the ventilation and massage components 6 can be used to ventilate the user's buttocks and massage the thighs.

[0034] Specifically, in order to achieve active or passive exercise of the user's legs and hands, refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the active and passive components 5 include rectangular holes 51 symmetrically arranged on the inner surface of the chair back 2, and the inner surfaces of the two rectangular holes 51 are both provided with a rotating lifting mechanism 52. Active mechanisms 53 are symmetrically arranged at the left and right ends of the frame 1, and the upper ends of the two active mechanisms 53 are both provided with a fixing mechanism 54. The rear end of the chair back 2 is symmetrically provided with a hand exercise mechanism 55, and the rear end of the chair back 2 is provided with a supporting mechanism 56.

[0035] For further information, see Figure 2 and Figure 3 In this embodiment, the rotating lifting mechanism 52 includes a gear 521 fixedly connected to both ends of the rotating shaft of the seat cushion 3, the rear parts of the inner surfaces of the two rectangular holes 51 are fixedly connected with a fixing block 522, the lower ends of the two fixing blocks 522 are fixedly installed with an electric telescopic rod 523, the lower ends of the two electric telescopic rods 523 are fixedly connected with a rack 524 meshing with the gear 521, the front parts of the inner surfaces of the two rectangular holes 51 are slidably connected with a rack 526 meshing with the gear 521, and the upper ends of the two racks 526 are fixedly connected with an armrest frame 525 slidably connected to the chair back 2.

[0036] During implementation, when the patient needs to assist walking, the electric telescopic rod 1 523 is powered by the relevant energy storage battery, and then the electric telescopic rod 1 523 is started to push the rack 1 524 to move downward. Since the rack 1 524, the gear 1 521 and the rack 2 526 are all meshingly connected, the rack 1 524 drives the gear 1 521 to rotate during the downward movement, and then drives the rack 2 526 to move upward, which can drive the armrest 525 to move upward. The rotation of the gear 1 521 will rotate the cushion 3 into the groove in the chair back 2, so that the cushion 3 can be completely stored. Then the user can face the front end of the chair back 2, hold the armrest 525 with his hands, and perform walking assistance movements to increase the support point for the user's walking. At the same time, when the user is sitting in the wheelchair, the above steps can be reversed to make the armrest 525 descend and limit the user.

[0037] For further information, see Figure 2 and Figure 4 In this embodiment, the active mechanism 53 includes a fixed block 2 531 fixedly connected to the right end of the frame 1, an electric telescopic rod 2 532 is fixedly installed at the front end of the fixed block 2 531, a spring telescopic rod 533 is fixedly connected to the front end of the electric telescopic rod 2 532, a rotating rod 535 is rotatably connected to the inner surface of the frame 1, a rack 3 534 is fixedly connected to the front end of the spring telescopic rod 533, a gear 2 536 meshing with the rack 3 534 is fixedly connected to the right end of the rotating rod 535, and a pedal 537 is rotatably connected to the inner surface of the rotating rod 535.

[0038] For further information, see Figure 2 , Figure 4 and Figure 5 In this embodiment, the fixing mechanism 54 includes a square hole block 541 fixedly connected to the left upper end of the footrest 537, and a fixing belt 542 is fixedly connected to the right upper end of the footrest 537. The outer surfaces of the fixing belt 542 are respectively fixedly connected with Velcro 1 543 and Velcro 2 544, and Velcro 1 543 and Velcro 2 544 are bonded to each other.

[0039] For further information, see Figure 2 and Figure 6 In this embodiment, the hand exercise mechanism 55 includes an L-shaped rod 551 fixedly connected to the right rear end of the chair back 2, a limiting rod 552 fixedly connected to the left inner surface of the frame 1, the front end of the limiting rod 552 passes through and extends to the front end of the L-shaped rod 551 and is slidably connected to a pull rope 554 fixedly connected to the rear end of the rotating rod 535, the outer surface of the pull rope 554 is fixedly connected to a square block 553 slidably connected to the inner surface of the L-shaped rod 551, and the upper end of the square block 553 is fixedly connected to a return spring 555 fixedly connected to the upper inner surface of the L-shaped rod 551.

[0040] During the implementation process, when the user needs to perform passive exercises on the hands and legs, the user can place the foot on the footrest 537, pass the fixing belt 542 through the square hole block 541, and then adhere the Velcro 1 543 and the Velcro 2 544 together to fix the user's foot. Then, the electric telescopic rod 2 532 is started to push the spring telescopic rod 533 to be compressed. When the spring telescopic rod 533 is compressed to the point where it cannot be compressed, the rack 3 534 is pushed to move forward. Since the rack 3 534 is meshed with the gear 2 536, the gear 2 536 drives the rotating rod 535 to rotate, so that the user's legs can perform passive exercises. At the same time, the forward and backward movement of the rotating rod 535 will pull the drawstring 554, so that the user's hand can perform corresponding passive movements with the leg while holding the draw ring on the drawstring 554.

[0041] Secondly, when the user needs to actively exercise the hands and legs, the user can push the rotating rod 535 to rotate through the legs, so that the gear two 536 drives the rack three 534 to move back and forth, and the spring telescopic rod 533 is in a compressed or stretched state, and at the same time, the hands can be driven to perform passive exercises. The user can also pull the pull rope 554 by hand to compress the reset spring 1 555, and pull the rotating rod 535 to rotate, thereby realizing active exercise of the user's hands and passive exercise of the legs or passive exercise of the hands and active exercise of the legs, which can effectively enhance muscle strength, improve joint flexibility, promote blood circulation, prevent muscle atrophy and joint stiffness, help to improve physical strength, improve cardiopulmonary function, promote self-motor ability, and reduce the risk of bedsores.

[0042] The electric telescopic rod 1 523 and the electric telescopic rod 2 532 mentioned above are both mature driving technology means and equipment in the prior art. In this solution, the electric telescopic rod 1 523 and the electric telescopic rod 2 532 can be powered by a relevant mobile power supply, and their internal structure, principle and connection method will not be elaborated again.

[0043] For further information, see Figure 2 and Figure 7 In this embodiment, the support mechanism 56 includes a support frame 561 fixedly connected to the rear end of the chair back 2, and a round rod 562 is rotatably connected to the inner surface of the support frame 561, and rollers 563 are symmetrically fixedly connected to the left and right ends of the round rod 562.

[0044] As can be seen from the above, when a user is sitting in a wheelchair and encounters a small uphill slope, the support frame 561 and the roller 563 can cooperate to prevent the user from falling backwards, thereby improving the user's safety.

[0045] Embodiment 2: Based on Embodiment 1, this embodiment adds a ventilation massage component 6 for massaging the user's legs and ventilating the buttocks, thereby achieving the purpose of massaging the user's legs and ventilating the buttocks.

[0046] Specifically, in order to massage the user's legs and ventilate the buttocks, refer to Figure 2 , Figure 8 , Fig. 9 and Fig.10 In this embodiment, the ventilation massage component 6 includes a plurality of ventilation holes 61 opened at the upper end of the seat cushion 3, a ventilation mechanism 62 is arranged at the lower end of the seat cushion 3, and a massage mechanism 63 is arranged at the front part of the inner cavity of the seat cushion 3.

[0047] For further information, see Figure 2 , Figure 8 and Fig. 9 In this embodiment, the ventilation mechanism 62 includes a partition 621 fixedly connected to the inner surface of the cushion 3, a rectangular box 622 is fixedly connected to the front of the lower end of the cushion 3, a motor 624 is fixedly connected to the lower inner surface of the rectangular box 622, a concave plate 623 fixedly connected to the inner surface of the rectangular box 622 is fixedly connected to the front end of the partition 621, a rotating rod 625 fixedly connected to the output end of the motor 624 through a coupling is rotatably connected to the lower end of the concave plate 623, a fan blade 626 is fixedly connected to the outer surface of the rotating rod 625, a heating tube 627 is symmetrically fixedly installed on the front end of the partition 621, a connecting tube 628 is fixedly connected to the rear of the inner surface of the rectangular box 622 symmetrically, and extends to the rear side of the lower inner surface of the cushion 3, and the upper ends of the two connecting tubes 628 are fixedly connected to conical blocks 629.

[0048] During implementation, when the user sits on the cushion 3 for a long time in summer or winter, the user can start the motor 624 so that the output end of the motor 624 drives the fan blade 626 on the rotating rod 625 to rotate through the coupling, and the air is sucked into the space formed by the concave plate 623 and the rectangular box 622 through the air inlet at the lower end of the rectangular box 622, and then enters the left and right spaces in the inner cavity of the rectangular box 622 through the holes on the concave plate 623. The air can be heated by the heating tube 627, and the wind is evenly blown out through the ventilation hole 61 by the cooperation of the connecting tube 628 and the conical block 629. In summer, the heating tube 627 can be closed, which can effectively improve air circulation and reduce skin problems caused by friction and moisture when the patient sits for a long time. Good ventilation can keep the skin dry and reduce the growth of bacteria and fungi, thereby effectively preventing the formation of bedsores. In addition, air circulation can promote local blood circulation, relieve blood stagnation caused by long-term compression, improve the oxygen supply to the skin, enhance the skin's self-repair ability, and further reduce the risk of skin damage.

[0049] The heating tube 627 mentioned above is a mature heating technology means and equipment in the prior art. In this solution, its heating function is utilized, and its internal structure, principle and connection method are not further explained.

[0050] For further information, see Figure 2 and Fig.10 In this embodiment, the massage mechanism 63 includes a reciprocating rod 632 that is rotatably connected to the front end of the partition 621 and the front part of the inner surface of the rectangular box 622. The outer surface of the reciprocating rod 632 is symmetrically slidably connected with a slider 633. The upper ends of the two sliders 633 are symmetrically fixedly connected with a plurality of semicircular blocks 634. The upper end of the seat cushion 3 is provided with a plurality of connecting holes 631. The upper inner surface of the seat cushion 3 is located below the connecting holes 631 and is fixedly connected with a plurality of fixing plates 635. The inner surfaces of the plurality of fixing plates 635 are slidably connected with sliding rods 636. The upper and lower ends of the plurality of sliding rods 636 are symmetrically fixedly connected with semicircular blocks 637. The outer surfaces of the plurality of sliding rods 636 are sleeved with return springs 638. The two ends of the return springs 638 are respectively fixedly connected with the upper end of the fixing plate 635 and the lower end of the upper semicircular block 637. The upper end of the rotating rod 625 and the middle of the outer surface of the reciprocating rod 632 are fixedly connected with a transmission mechanism 639.

[0051] During the implementation process, since the rotating rod 625 will drive the reciprocating rod 632 to rotate through the transmission mechanism 639 during the rotation process, since the reciprocating rod 632 and the slider 633 are slidably connected, and the lower end of the slider 633 is in close contact with the lower part of the inner surface of the seat cushion 3, the reciprocating rod 632 drives the two sliders 633 to reciprocate back and forth during the rotation, so that the semicircular block 1 634 can squeeze the semicircular block 2 637 located at the bottom, push the slide bar 636 to slide upward on the inner surface of the fixed plate 635, and compress the return spring 2 638, and push the semicircular block 2 637 located at the upper part out of the connecting hole 631 to massage the patient's legs. When the semicircular block 1 634 is away from the semicircular block 2 637 located at the bottom, the semicircular block 2 637 located at the bottom will be reset under the compression reaction force of the return spring 2 638. Massaging the patient's thigh helps to promote blood circulation, relieve muscle tension and pain, and reduce muscle stiffness and atrophy caused by long-term sitting or limited movement. Massage can also improve joint flexibility, promote lymphatic drainage, and reduce edema, while enhancing the patient's comfort and relaxation, helping to improve overall health and prevent health problems caused by lack of exercise.

[0052] The transmission mechanism 639 mentioned above is composed of two bevel gears in the prior art.

[0053] The reciprocating rod 632 and the sliding block 633 described above constitute a mature ball screw mechanism in the prior art, and the reciprocating grooves on the outer surface of the reciprocating rod 632 are symmetrically distributed.

[0054] Working process: When in use, the user can sit on the seat cushion 3 or the seat cushion 3 can be stored in the chair back 2 by rotating the lifting mechanism 52, so that the user can use a wheelchair to assist walking. The user's hands and legs can be actively or passively exercised with the cooperation of the active mechanism 53, the fixing mechanism 54 and the hand exercise mechanism 55. The user's buttocks can be ventilated and the legs can be massaged with the cooperation of the ventilation mechanism 62 and the massage mechanism 63.
