[0036] The working principle and use process of the present invention are as follows: when in use, the wheelchair realizes flexible conversion of the seat through the split design of the backrest 1, seat 2 and bracket 3, and the symmetrical arrangement of the first rotating plate 4 and the second rotating plate 5. When the wheelchair needs to be converted into a stretcher or a simple bed, first, the backrest 1, seat 2 and the rotating plate can be flexibly rotated through the rotation connection of the first rotating shaft 6 and the second rotating shaft 7. Then, the first electric push rod 17 and the second electric push rod 18 are driven to retract, so that the backrest 1 and the bracket 3 are connected to the first rotating seat 15 and the second rotating seat 16 respectively, thereby realizing the expansion of the backrest and the bracket. At the same time, the seat 2 is connected to the top of the bracket 9 by sliding, and cooperates with the expansion plate 8 so that the seat can be folded horizontally and vertically to meet the needs of the user. In order to meet the demand for a fast stretcher, the control panel 12 is located on the top of the backrest 1, which is convenient for operating the electric push rod. The distribution box 11 is fixed inside the bracket to provide power for the electric push rod. In addition, the leg support 19 can improve the comfort of the patient when stepping on the foot pedal 20. The third rotating seat 21, the support leg 22 and the second roller 23 in the supporting moving mechanism work together to enable the wheelchair to move stably during the conversion process. The locking ring 24 is used to fix the support leg 22 to ensure safety. The design of the armrest 25 and the guardrail 26, on the one hand, is convenient for the patient to support, and on the other hand, it plays a limiting role when lying down to prevent falls. In summary, the utility model realizes the fast and safe conversion between the wheelchair and the stretcher through a series of ingenious designs, which provides great convenience for people with mobility difficulties.

[0037] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the various technical features in any other appropriate manner. These simple variations and combinations should also be considered as disclosed in the present invention and fall within the scope of protection of the present invention.
