The step unit includes a pedal and a baffle, one end of the baffle is rotatably connected to the chassis part, and the other end of the baffle is rotatably connected to the pedal through a rotating shaft;

The underframe part is provided with a two-link assembly that limits the position of the pedal; the two-link assembly includes a bent link connected to the pedal at one end, the other end of the bent link is connected to one end of the straight link, and the straight link The other end is rotatably connected to the chassis part, and the straight connecting rod is parallel to the baffle plate, and the middle part of the straight connecting rod is connected with a driving connecting rod that drives the straight connecting rod to turn outward, and the driving connecting rod passes through a middle The connecting rod is connected with the push rod;

The armrest on at least one side is detachable from the vehicle frame.

In a preferred embodiment of the present utility model, the push rod is an electric push rod.

In a preferred embodiment of the present invention, the wheels include four universal wheels.

When the drive rod drives the push rod to turn inwards, and at the same time controls the push rod to shrink, the backrest unit turns backward around a rotation axis, and the push rod drives the middle link, the drive link, and the second link assembly to move, so that they are connected to the second link assembly The pedals and baffles flip over to be on the same plane as the cushion unit. After the armrest is disassembled so that it is side by side with the specific half medical bed, the wheelchair bed and the half medical bed are fixed together by buckles.

The utility model can lie flat and can be used in combination with a specific medical bed. The utility model has the advantages of simple structure and convenient and fast folding process.

The features of the utility model can be clearly understood by referring to the drawings of this case and the detailed description of the following preferred embodiments.
