[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] Example 1

[0041] Please refer to Figure 1 , Figure 2 and Figure 3 A rehabilitation training wheelchair includes a control box 1. The control box 1 contains two sets of batteries. When electrical energy is recovered through a generator in a training component 4, one set of batteries is charged, while the other set provides power to a geared motor 22, enabling it to operate. A drive component 2 is located outside the control box 1. A driven component 3 is located at the front end of the drive component 2. A training component 4 is located between the drive component 2 and the driven component 3. During rehabilitation training, the user's legs step on a transmission component 5 to perform the training, and power is recovered through the training component 4. The transmission component 5 is located inside the training component 4. A conversion component 6 is located at the top of the drive component 2. A support component 7 is located at the top of the conversion component 6. An auxiliary suspension component 8 is located above the support component 7 to support the user's body, enabling the user to stand. A pressure relief component 9 is located at the top of the control box 1 to prevent the batteries or controller inside the control box 1 from exploding.

[0042] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, the drive assembly 2 includes two primary support rods 21, with the front ends of the two primary support rods 21 tilting upwards. The control box 1 is fixed between the two primary support rods 21. A reduction motor 22 is fixedly installed at the rear end of the primary support rod 21. The reduction motor 22 includes, but is not limited to, a gear reduction motor and a planetary gear reduction motor. The reduction motor 22 is electrically connected to the battery inside the control box 1 through a controller. A drive wheel 23 is fixedly installed at the output end of the reduction motor 22. When the reduction motor 22 starts, it causes the drive wheel 23 to rotate, driving the drive assembly 2 and the driven assembly 3 to move. An auxiliary frame 24 is provided at the bottom end of the reduction motor 22. The rear end of the auxiliary frame 24 tilts downwards. An auxiliary wheel 25 is rotatably installed at the rear end of the auxiliary frame 24. The auxiliary frame 24 contacts the ground support through the auxiliary wheel 25, thereby increasing the fulcrum and preventing the wheelchair from tipping over. A secondary support rod 26 is fixedly installed at the top end of the primary support rod 21.

[0043] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the driven component 3 includes a third support rod 31. Both ends of the third support rod 31 are fixedly provided with a fixed seat 32. The bottom end of the fixed seat 32 is provided with a universal wheel 33, which is used to support the front part. The rear end of the fixed seat 32 is inclinedly fixedly provided with a first fixed rod 34. The rear end of the first fixed rod 34 is fixedly connected to the bottom end of the first support rod 21. The two first fixed rods 34 are hinged to opposite sides with a placement plate 35. The hinge point between the placement plate 35 and the first fixed rod 34 has a certain friction force, so the placement plate 35 can be used to control whether it is upright and folded up or laid flat. When laid flat, it can be used to place the user's feet.

[0044] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the training component 4 includes a fourth fixed rod 44, which is fixed between two reduction motors 22. Two second fixed rods 41 are fixed to the bottom of the fourth fixed rod 44. A fifth fixed rod 45 is fixed in front of the two second fixed rods 41. The fifth fixed rod 45 is fixedly connected to the bottom of the third support rod 31. Two third fixed rods 42 are fixed behind the four fixed rods 44. A transmission wheel 43 is rotatably mounted behind the two second fixed rods 41. The transmission wheel 43 is located between the two third fixed rods 42. A generator is fixedly connected to the second fixed rod 41 on one side of the transmission wheel 43. The generator is a dual-shaft generator. The generator is electrically connected to the battery inside the control box 1 through a controller. When the transmission wheel 43 rotates, it recovers electrical energy through the generator and transmits it to the battery pack inside the control box 1 to charge the battery.

[0045] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the transmission assembly 5 includes two transmission rods 51, which are located on both sides of the transmission wheel 43. The transmission rod 51 located on the side of the transmission wheel 43 away from the generator passes through the second fixed rod 41 through a shaft and is fixedly connected to the transmission wheel 43. The transmission rod 51 on the same side as the generator is fixedly connected to another output shaft of the generator. When the transmission assembly 5 is used to drive the transmission wheel 43 to rotate, the generator recovers electrical energy.

[0046] An adjusting rod 52 is rotatably provided on the side of the transmission rod 51 away from the transmission wheel 43. That is, the two ends of the transmission rod 51 on the side of the transmission wheel 43 away from the generator are respectively connected to the transmission wheel 43 and the adjusting rod 52. The two ends of the transmission rod 51 on the same side as the generator are respectively connected to the generator output end and the adjusting rod 52 on the same side. The two output ends of the generator are respectively fixedly connected to the transmission wheel 43 and the transmission rod 51 on the same side. The generator is located between the transmission wheel 43 and one of the transmission rods 51. A connecting cylinder 53 is slidably provided on the outside of the adjusting rod 52.

[0047] The adjusting rod 52 has several control holes equidistantly arranged on it. The control holes are used to adjust the length of the combination of the adjusting rod 52 and the connecting cylinder 53. A bolt 57 is provided at the rear of the top of the connecting cylinder 53. The end of the bolt 57 passes through one of the control holes on the connecting cylinder 53 and the adjusting rod 52 and is threadedly connected to the connecting cylinder 53. When it is necessary to adjust the length of the connecting cylinder 53 and the adjusting rod 52, the adjusting rod 52 is pulled to make it slide inside the connecting cylinder 53. After adjusting to the required length, the corresponding control hole is aligned with the hole on the connecting cylinder 53 for the bolt 57 to pass through. Then the bolt 57 is rotated to pass through the connecting cylinder 53 and the corresponding control hole through the thread and tightened to complete the positioning.

[0048] Below the second fixing rod 41, there is a first connecting seat 54. The first connecting seat 54 is used to prevent the pulley 55 from completely disengaging from the second fixing rod 41. Inside the first connecting seat 54, there is a pulley 55 located above the second fixing rod 41. The second fixing rod 41 contacts the pulley 55. When the user steps on the transmission component 5, the connecting cylinder 53 will move back and forth, and the pulley 55 will contact the second fixing rod 41 and roll, reducing friction. Outside the first connecting seat 54, there is a second connecting seat 56. The second connecting seat 56 is fixedly connected to the connecting cylinder 53. The top of the connecting cylinder 53 is fixedly equipped with a pedal 58 in front of the first bolt 57.

[0049] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the conversion component 6 includes a seat plate 65. Connecting blocks 63 are rotatably provided on the upper sides of both sides of the seat plate 65. The lower side of the connecting blocks 63 is rotatably connected to the seat plate 65. A first mounting rod 62 is rotatably provided on the side of the connecting blocks 63 away from the seat plate 65. The middle part of one side of the connecting blocks 63 is rotatably connected to the first mounting rod 62. The end of the first mounting rod 62 is rotatably connected to the front end of the first support rod 21. The rotatable connection with the first support rod 21 adapts to the angle change brought about by the extension and retraction of the drive telescopic rod 61 and provides a certain support force. The drive telescopic rod 61 is specifically an electric telescopic rod.

[0050] The lower sides of both sides of the seat 65 are provided with second mounting rods 64. The ends of the second mounting rods 64 are rotatably connected to the second support rods 26. The two first support rods 21 are rotatably provided with drive telescopic rods 61 on opposite sides. The drive telescopic rods 61 are activated to extend and retract, and cooperate with the support assembly 7 to change shape. The output end of the drive telescopic rods 61 is rotatably connected to the upper side of the connecting block 63. The same third mounting rod 66 is fixedly provided below the rear end of the two connecting blocks 63. The third mounting rod 66 is used to connect with the support assembly 7.

[0051] Furthermore, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the support assembly 7 includes a back plate 71, which is rotatably connected between two connecting blocks 63. The middle of the side of the connecting block 63 is rotatably connected to the back plate 71. Two fixing plates 72 are fixedly provided on both sides of the rear end of the back plate 71. A fourth mounting rod 73 is fixedly provided between the two fixing plates 72. A transmission telescopic rod 74 is hinged to the top of the third mounting rod 66. The transmission telescopic rod 74 is specifically an electric telescopic rod.

[0052] When the transmission telescopic rod 74 is activated to shorten it, the two connecting blocks 63 are pulled downwards and flipped backwards by the third mounting rod 66, causing the seat 65 to move backwards. However, due to the connection between the second mounting rod 64 and the second support rod 26, the bottom of the seat 65 flips forward. In conjunction with the extension and retraction of the drive telescopic rod 61, the seat 65 is flipped forward, transforming it into a seat cushion for the user to sit on. The output end of the transmission telescopic rod 74 is hinged to the fourth mounting rod 73. Armrests 75 are fixed on both sides of the backrest 71. The rear ends of the two fixed plates 72 are fixed with the same handle 76. By grasping the handle 76 and pushing, the user sitting on the seat 65 is propelled.

[0053] Example 2

[0054] The rehabilitation training wheelchair provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the auxiliary lifting assembly 8 includes two L-shaped rods 81, which are used to support the user. The two L-shaped rods 81 are located on opposite sides of the two fixed plates 72. Several through holes 83 are equidistantly opened above the L-shaped rods 81. A cloth strip or rope is passed through the through holes 83 and the two ends of the cloth strip or rope are tied to form a loop. The user's two hands are passed through the loop cloth strip or rope on both sides and supported under the armpits to help the user stand. Several adjustment holes 82 are equidistantly opened below the through holes 83. The adjustment holes 82 are used to adjust the height of the through holes 83 with the help of bolt No. 2 84.

[0055] Two No. 2 bolts 84 are provided on opposite sides of the two L-shaped rods 81. The ends of the No. 2 bolts 84 pass through one of the adjustment holes 82 on the L-shaped rod 81 and the fixing plate 72 and are threadedly connected to the fixing plate 72. When it is necessary to adjust the height of the L-shaped rods 81, the two L-shaped rods 81 are moved up and down to adjust to the required height, and the adjustment holes 82 at the corresponding positions are aligned with the holes on the side of the fixing plate 72 for threaded connection with the No. 2 bolts 84. Then, the two bolts are passed through two of the adjustment holes 82 on the through hole 83 and rotated to engage with the fixing plate 72, thereby locking the position of the L-shaped rods 81.

[0056] Example 3

[0057] The rehabilitation training wheelchairs provided in Examples 1 and 2 have been further optimized, such as... Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the top of the control box 1 has an opening that communicates with the interior of the control box 1. The pressure relief assembly 9 includes a mounting box 91 fixed to the top of the control box 1 on one side of the opening. Several springs 93 are fixed inside the mounting box 91. The elastic force of the springs 93 causes the limiting block 97 at the end of the slider 92 to contact the limiting groove 96 on the limiting plate 95 and prevents the limiting plate 95 from opening. The slider 92, which is fixedly connected to several springs 93, is slidably mounted inside the mounting box 91. The top of the control box 1 is fixedly mounted on the other side of the opening. The limiting plate 95 is rotatably mounted inside the mounting seat 94.

[0058] When the pressure inside the control box 1 increases, it will push open the limiting plate 95. Several limiting grooves 96 are provided on the side of the limiting plate 95 near the slider 92. The limiting grooves 96 provide a certain resistance to the opening and closing of the limiting plate 95 through the elastic force of the spring 93. The limiting plate 95 will only be pushed open when the pressure inside the control box 1 reaches a certain level. The limiting groove 96 is provided with a limiting block 97 fixedly connected to the slider 92. The limiting block 97 is arc-shaped, and the shape inside the limiting groove 96 matches the limiting block 97.

[0059] When the battery or controller inside the control box 1 catches fire, the pressure inside the control box 1 will increase, causing it to explode. At this time, the pressure inside the control box 1 will push the limiting plate 95 outward and break through the elastic force of the spring 93, causing the slider 92 to retract into the mounting box 91. The limiting groove 96 on the limiting plate 95 will separate from the limiting block 97, and the limiting plate 95 can be opened to release pressure and prevent an explosion.

[0060] Furthermore, such as Figure 7 and Figure 8 As shown, a connecting frame 98 is fixedly provided inside the opening, and a contact pad 99 is fixedly connected to the limiting plate 95 at the top of the connecting frame 98. The connecting frame 98 contacts the contact pad 99, and the contact pad 99 includes, but is not limited to, a rubber pad, for providing a certain degree of sealing.

[0061] The rehabilitation training wheelchair provided by this utility model is used as follows:

[0062] When rehabilitation training is required using training component 4 and transmission component 5, the cloth strip or rope is passed through the through hole 83 and the two ends of the cloth strip or rope are tied together to form a loop. The user's two hands are passed through the loop cloth strip or rope on both sides, and the armpit support is used to support and assist the user in standing. The user's legs are placed in the two pedals 58 respectively. Then the user steps on the pedals 58 to make a pedal-like movement, which drives the connecting cylinder 53 and the adjusting rod 52 to move back and forth. The pulley 55 contacts the second fixed rod 41 to reduce friction, and the transmission rod 51 drives the transmission wheel 43 to rotate. In conjunction with starting the reduction motor 22, the wheelchair is moved, which greatly reduces the resistance when the user steps on the pedals 58, thereby enabling rehabilitation training.

[0063] During the rotation of the transmission wheel 43, electricity is recovered by a generator on one side and stored in the battery inside the control box 1. The two sets of batteries inside the control box 1 are used to store the electrical energy recovered by the generator and to power the geared motor 22. When the battery that powers the geared motor 22 is depleted, the two sets of batteries switch their functions. The battery that originally powered the geared motor 22 stores the electrical energy recovered by the generator, and the battery that originally stored the electrical energy generated by the generator powers the geared motor 22. This avoids the problem of the battery overheating due to charging while in use and improves the battery's lifespan.

[0064] When the seat 65 needs to be flipped forward and used as a cushion by changing component 6 and support component 7, activate the transmission telescopic rod 74 to shorten it, causing the connecting block 63 to flip backward, causing the seat 65 to flip around the second mounting rod 64 as the fulcrum. Then activate the drive telescopic rod 61 to extend it, causing the connecting block 63 and backrest 71 to move upward, making the seat 65 vertical. At this time, manually push the bottom of the seat 65 forward, so that the bottom of the seat 65 is in front. With the drive telescopic rod 61 shortened and the transmission telescopic rod 74 extended, the bottom of the seat 65 will gradually flip forward until it is close to a right angle with the backrest 71, and the user can sit on the seat 65.
