[0067] The working principle of this embodiment is as follows:

[0068] The sofa joint hinge 8 is provided with a plurality of gears, each gear corresponding to a different turning angle. The seat 1 is switched to a folded state (the angle between the hip pad 5 and the back pad 6 is close to 90 degrees, and the angle between the hip pad 5 and the leg pad 7 is close to 100 degrees) with the cooperation of its sofa joint hinge 8, and is fixedly installed on the seat support seat 2 which is also in the folded state by means of a clevis bolt assembly. In addition, by adjusting the corresponding spiral locking structure, the angle between the first handle 4 located at the top of the seat 1 and the seat 1 is adjusted to be close to 90 degrees, which is convenient for family members, caregivers or medical staff to push the wheelbarrow; and the first handle 4 located at the bottom end of the seat 1 is rotated to be close to the bottom end of the seat 1; the armrest 13 is limited by the limiting part on the side of the back pad 6; at this time, the multifunctional wheelchair is used as an ordinary wheelchair, which is suitable for disabled persons who can sit, as shown in the following example. Figure 1 shown.

[0069] When the multifunctional wheelchair is used to transport disabled persons who can only lie down on flat ground, the seat cushion and the cushion seat are adjusted to a horizontally extended state, and the armrest 13 is limited by the limit seat 15 on the back of the back cushion seat 10. Figures 2 to 4 shown.

[0070] When the multifunctional wheelchair is used to transport disabled persons who can only lie down when going up and down stairs, not only the seat cushion and the cushion seat are adjusted to a horizontally extended state, the armrest 13 is limited by the limit seat 15 on the back of the back cushion seat 10, but also the seat support seat 2 is adjusted to an extended state, and the second handle 24 is rotated and pulled out, such as Figure 5 As shown. The seat support 2 is adjusted to the extended state, specifically: rotate the component A in the corresponding spiral locking structure, unlock the locking state of the first support rod 21 and the second support rod 22, and give the hip pad 5 a downward pressure, so that the first support rod 21 rotates relative to the second support rod 22, and the extension frame 19 moves along the slide rail 18 in the direction away from the axis of the second pulley 3. After the seat support 2 is fully extended, rotate component A in the opposite direction, lock the locking state of the first support rod 21 and the second support rod 22, so that the seat support 2 remains in the extended state. When the stairs are finished and it is necessary to continue to be transported on the flat ground, the seat support 2 is transformed into the folded state.

[0071] In addition to the above state, depending on the specific situation, if only a short distance is needed or the ground is not flat, the seat 1 can be separated from the seat support base 2 by adjusting the clevis bolt assembly, such as Figure 6 As shown, when the seat 1 is in the extended state and is used alone, the first handle 4 at the top of the seat 1 and the first handle 4 at the bottom of the seat 1 are both 180 degrees apart from the seat 1. At this time, the seat 1 and the first handles 4 at both ends cooperate to form a stretcher shape.

[0072] When the multifunctional wheelchair needs to be folded, the seat 1 and the seat support 2 are both transformed into the extended state. The multifunctional wheelchair in this state can be stacked together for storage, occupying less space.

[0073] The embodiments described above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made based on the shape and principle of the present invention should be included in the protection scope of the present invention.
