[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present invention provides an upper and lower limb rehabilitation training vehicle, which has the following beneficial effects:

[0015] The upper and lower limb rehabilitation training vehicle, through the above, if the patient needs to perform rehabilitation training for the lower limbs, first rotate the knob to the left, the rotating knob drives the eccentric wheel to rotate, the toggle block on the eccentric wheel makes the self-locking disk move to the left, when the self-locking disk moves to the left, the self-locking disk squeezes the spring, and then starts the driving motor, the driving motor makes the first rotating rod rotate at a uniform speed through the commutator, during the rotation of the first rotating rod, the first rotating disk drives the second rotating disk through the transmission belt, the second rotating disk idles on the second rotating rod, and the foot pedal is driven separately;

[0016] If the patient needs to perform rehabilitation training for his limbs, the knob is rotated to the right so that the toggle rod on the eccentric wheel releases the restriction on the self-locking disk. The self-locking disk limits the moving trajectory through the spline, and the spring moves the self-locking disk to the right through its own elastic force. During the movement of the self-locking disk, the plug-in rod is inserted into the plug-in hole to achieve connection. When the transmission belt drives the second rotating disk to rotate, if the plug-in rod is not aligned with the plug-in hole, the second rotating disk rotates idly at a uniform speed. During the idling of the second rotating disk, the plug-in rod is always in contact with the side wall of the second rotating disk. When the plug-in rod is aligned with the plug-in hole, the plug-in rod is inserted into the plug-in hole. At this time, the second rotating disk drives the second rotating rod to rotate through the self-locking disk, the spline and the plug-in rod, and then the second rotating rod drives the handle to rotate;

[0017] If the patient only needs rehabilitation training for the upper limbs, the knob is rotated to the left. The rotating knob drives the eccentric wheel to rotate, and the toggle block on the eccentric wheel causes the self-locking disk to move to the left. When the self-locking disk moves to the left, the self-locking disk squeezes the spring, and then the patient holds the two handles for manual drive, thereby achieving independent upper limb movement, independent lower limb movement and four limb movement, reducing the inconvenience brought by traditional rehabilitation training vehicles, and can also adapt to the rehabilitation training needs of multiple patients, thereby improving overall practicality.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-6, the present invention provides a technical solution: an upper and lower limb rehabilitation training vehicle, including a chassis 1, a top end of the chassis 1 is fixedly provided with an outer protective shell 2, a top end of the outer protective shell 2 is fixedly provided with a column 3, a front side wall of the column 3 is provided with a rotatable knob 4, an inner protective shell 5 is fixedly arranged in a cavity of the column 3, a bottom of the inner protective shell 5 is located in a cavity of the outer protective shell 2, an eccentric wheel 6 is arranged inside the inner protective shell 5, and a rear end of the knob 4 is connected to the eccentric wheel 6, a commutator 7 is arranged at a bottom of the inner protective shell 5, and a driving motor is arranged on the commutator 7, a rotatable first rotating rod 8 is arranged on the commutator 7, and a first rotating disk 9 is fixedly arranged on the first rotating rod 8, left and right ends of the first rotating rod 8 pass through side walls of the inner protective shell 5 and the outer protective shell 2, mounting brackets 10 are symmetrically arranged inside a top of the outer protective shell 2, a rotatable second rotating rod 11 is arranged on the mounting bracket 10, a rotatable second rotating disk 12 is arranged on the second rotating rod 11, circular array insertion holes are arranged on a left side wall of the second rotating disk 12, a self-locking disk 13 is slidably arranged on the second rotating rod 11, a spline 14 cooperating with the self-locking disk 13 is arranged on an outer side wall of the second rotating rod 11, circular array insertion rods 15 are arranged on a right end of the self-locking disk 13, and the insertion rods 15 can be inserted into the insertion holes, the eccentric wheel 6 is composed of a turntable and a toggle rod, and the toggle rod is located in a gap between the second rotating disk 12 and the self-locking disk 13, connecting rods 16 are fixedly arranged on left and right ends of the first rotating rod 8, and a foot pedal 17 is arranged on the connecting rod 16, handles 18 are arranged on left and right ends of the second rotating rod 11, a spring 19 is sleeved on the second rotating rod 11, and left and right ends of the spring 19 respectively abut against the inner protective shell 5 and the self-locking disk 13, a transmission belt 20 is sleeved on the first rotating disk 9 and the second rotating disk 12, a damping component is arranged on the knob 4. Through the above, if a patient needs to perform rehabilitation training on the lower limbs, first rotate the knob 4 to the left. The rotated knob 4 drives the eccentric wheel 6 to rotate. A toggle block on the eccentric wheel 6 moves the self-locking disk 13 to the left. When the self-locking disk 13 moves to the left, the self-locking disk 13 squeezes the spring 19. Then start the driving motor. The driving motor drives the first rotating rod 8 to rotate at a constant speed through the commutator 7. During the rotation of the first rotating rod 8, the first rotating disk 9 drives the second rotating disk 12 through the transmission belt 20. The second rotating disk 12 idles on the second rotating rod 11 to realize the independent driving of the foot pedal 17;

[0027] If the patient needs to perform rehabilitation training for his limbs, the knob 4 is rotated to the right, so that the toggle rod on the eccentric wheel 6 releases the restriction on the self-locking disk 13. The self-locking disk 13 limits the moving trajectory through the spline 14, and the spring 19 causes the self-locking disk 13 to move to the right through its own elastic force. During the movement of the self-locking disk 13, the plug-in rod 15 is inserted into the plug-in hole to achieve connection. When the transmission belt 20 drives the second rotating disk 12 to rotate, if the plug-in rod 15 is not aligned with the plug-in hole, the second rotating disk 12 rotates at a uniform speed. During the idling of the second rotating disk 12, the plug-in rod 15 is always in contact with the side wall of the second rotating disk 12. When the plug-in rod 15 is aligned with the plug-in hole, the plug-in rod 15 is inserted into the plug-in hole. At this time, the second rotating disk 12 drives the second rotating rod 11 to rotate through the self-locking disk 13, the spline 14 and the plug-in rod 15, and then the second rotating rod 11 drives the handle 18 to rotate;

[0028] If the patient only needs rehabilitation training for the upper limbs, the knob 4 is rotated to the left. The rotating knob 4 drives the eccentric wheel 6 to rotate, and the toggle block on the eccentric wheel 6 causes the self-locking disk 13 to move to the left. When the self-locking disk 13 moves to the left, the self-locking disk 13 squeezes the spring 19, and then the patient holds the two handles 18 for manual drive, thereby achieving independent upper limb exercise, independent lower limb exercise and four limb exercise, reducing the inconvenience brought by traditional rehabilitation training vehicles. Compared with the single rehabilitation exercise of traditional rehabilitation training vehicles, it can also adapt to the rehabilitation training needs of multiple patients, thereby improving the overall practicality.

[0029] If the patient's grip strength is weak, the handle 18 is prone to slipping when holding it. In the present invention, the handle 18 is provided with a plastic grip cover for anti-slipping. Through the above, since the handle 18 is provided with a plastic grip cover for anti-slipping, the patient's hand slipping when holding the handle 18 can be reduced, thereby improving the practicality of the handle 18.

[0030] When the sole of the foot steps on the foot pedal 17, it is easy to slip, and the foot pedal 17 is easy to cause bumps on the legs when sliding. In the present invention, the foot pedal 17 is provided with a plastic grid for increasing friction. Through the above, since the foot pedal 17 is provided with a plastic grid for increasing friction, the friction of the foot pedal 17 can be effectively increased, and the part where the sole of the foot and the foot pedal 17 are in contact can be avoided from slipping, thereby improving the practicality of the foot pedal 17.

[0031] When using the foot pedal 17, it is difficult to fix the soles of feet of different sizes. In the present invention, a detachable limiting plate 21 is provided at the left and right ends of the two foot pedals 17, and a detachable binding belt 22 is provided on the limiting plate 21, and the binding belt 22 has through holes arranged in a horizontal array, and the limiting plate 21 passes through the through holes of the binding belt 22. Through the above-mentioned limiting plate 21 and binding belt 22, the limiting plate 21 and the binding belt 22 can be adjusted and bound according to the soles of feet of different sizes, thereby achieving the fixation of the feet and improving the practicality of the foot pedal 17.

[0032] When using the binding belt 22, the binding belt 22 is prone to breakage due to its own low toughness. In the present invention, the binding belt 22 is made of a plastic material with good toughness as a whole. As described above, since the binding belt 22 is made of a plastic material with good toughness as a whole, the plastic material itself has good toughness, thereby reducing the occurrence of breakage and improving the practicality of the binding belt 22.

[0033] It is inconvenient for the staff to disassemble the outer protective shell 2 as a whole. They need to disassemble other parts first, and then disassemble and remove the outer protective shell 2. In the present invention, the outer protective shell 2 is composed of two shells, and the two shells are connected to each other by bolts. Through the above, since the outer protective shell 2 is composed of two shells, and the two shells are connected to each other by bolts, the maintenance personnel only need to unscrew the bolts during disassembly to realize the disassembly of the outer protective shell 2, so as to facilitate the staff to disassemble the outer protective shell 2 and improve the practicality of the outer protective shell 2.

[0034] In summary, the upper and lower limb rehabilitation training vehicle, through the above, if the patient needs to perform rehabilitation training for the lower limbs, first rotate the knob 4 to the left, the rotating knob 4 drives the eccentric wheel 6 to rotate, and the toggle block on the eccentric wheel 6 causes the self-locking disk 13 to move to the left. When the self-locking disk 13 moves to the left, the self-locking disk 13 squeezes the spring 19, and then starts the driving motor, and the driving motor causes the first rotating rod 8 to rotate at a constant speed through the commutator 7. During the rotation of the first rotating rod 8, the first rotating disk 9 drives the second rotating disk 12 through the transmission belt 20, and the second rotating disk 12 idles on the second rotating rod 11, thereby realizing the separate driving of the foot pedal 17;

[0035] When the patient needs to perform rehabilitation training on the limbs, rotate the knob 4 to the right, so that the toggle rod on the eccentric wheel 6 releases the restriction on the self-locking disc 13. The self-locking disc 13 restricts the movement track through the spline 14, and the spring 19 moves the self-locking disc 13 to the right through its own elastic force. During the movement of the self-locking disc 13, the insertion rod 15 is inserted into the insertion hole to achieve connection. The transmission belt 20 drives the second rotating disc 12 to rotate. If the insertion rod 15 is not aligned with the insertion hole, the second rotating disc 12 rotates at a constant speed idly. During the idle rotation of the second rotating disc 12, the insertion rod 15 always fits against the side wall of the second rotating disc 12. When the insertion rod 15 is aligned with the insertion hole, the insertion rod 15 is inserted into the insertion hole. At this time, the second rotating disc 12 drives the second rotating rod 11 to rotate through the self-locking disc 13, the spline 14 and the insertion rod 15, and then the second rotating rod 11 drives the handle 18 to rotate;

[0036] When the patient only needs to perform rehabilitation training on the upper limbs, rotate the knob 4 to the left. The rotating knob 4 drives the eccentric wheel 6 to rotate, and the toggle block on the eccentric wheel 6 moves the self-locking disc 13 to the left. When the self-locking disc 13 moves to the left, the self-locking disc 13 squeezes the spring 19, and then the patient holds the two handles 18 for manual driving, so as to realize single upper limb movement, single lower limb movement and limb movement, reduce the inconvenience brought by the traditional rehabilitation training vehicle, and can also meet the rehabilitation training needs of multiple patients, improving the overall practicality. Through the above, since the handle 18 is provided with a plastic grip for anti-slip, the situation of slipping off when the patient holds the handle 18 can be reduced, improving the practicality of the handle 18. Through the above, since the foot pedal 17 is provided with a plastic grid for increasing friction, the friction of the foot pedal 17 can be effectively increased, avoiding the situation of slipping between the part where the sole fits against the foot pedal 17, improving the practicality of the foot pedal 17. Through the above limiting plate 21 and binding belt 22, the limiting plate 21 and the binding belt 22 can be adjusted and tied according to the feet of different sizes, so as to realize the fixation of the feet, improving the practicality of the foot pedal 17. Through the above, since the binding belt 22 is made of a plastic material with good toughness as a whole, the plastic material itself has good toughness, thus reducing the occurrence of breakage and improving the practicality of the binding belt 22. Through the above, since the outer protective shell 2 is composed of two shells, and the two shells are connected to each other by bolts, the maintenance personnel only need to unscrew the bolts during disassembly to realize the disassembly of the outer protective shell 2, facilitating the staff to disassemble and improving the practicality of the outer protective shell 2.
