[0042] like Figures 1-5 As shown, the present invention provides an auxiliary device for getting on and off a wheelchair. The extension and retraction of the first telescopic rod 7 drives the T-shaped connecting rod 9 to move through the second hinge ring 12 in the hollow part of the connecting seat 10, thereby driving the left bottom rod 14. The ramp box 15 is raised by moving the T-shaped connecting rod 9, which in turn drives the second telescopic rod 16 and the vertical hinge rod 17 to rotate on the connecting seat 10 via the fourth hinge ring 18. This causes the bottom rod 20 to rise, which in turn causes the ramp box 15 to rise and fall, thus achieving the beneficial effect of adjusting the height. When the ramp box 15 is raised, the second telescopic rod 16 is retracted, causing the right end of the ramp box 15 to fall, thus creating a slope. Then, the telescopic cylinder 21 is extended and retracted, causing the first ramp connecting plate 23 to extend. By opening the second ramp connecting plate 24 and the third ramp connecting plate 25, the third ramp connecting plate 25 comes into contact with the upper raising block 27. The telescopic cylinder 21 controls the movement of the first ramp connecting plate 23, thus achieving the beneficial effect of adjusting the distance and height of the ramp.

[0043] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
