Wheelchair bed and deformation method thereof

The invention provides a wheelchair bed and a deformation method thereof, and relates to the technical field of medical instruments. The wheelchair bed comprises a bed body and a transmission mechanism. The bed body comprises a pedal, and the pedal is connected to the transmission mechanism. When the wheelchair bed is in a wheelchair form, the pedal is treaded, and the transmission mechanism transmits treading force, so that the wheelchair bed is deformed into a bed form. The deformation method of the wheelchair bed comprises the steps that: when the wheelchair bed is in a wheelchair form, thepedal is treaded, the transmission mechanism transmits treading force, and the wheelchair bed is deformed into a bed form. The wheelchair bed is transformed from the wheelchair form to the bed form,only the pedal needs to be treaded to provide power, deformation can be completed through transmission of the transmission mechanism, a motor and a mobile power source do not need to be additionally installed, the cost is low, and the mass is small. According to the deformation method of the wheelchair bed, the wheelchair bed can be conveniently deformed into the bed form from the wheelchair form.
