The working principle of the transfer mechanism is as follows: when the sitting-lying patient transfer machine of the present invention is in the form of a stretcher, the four transfer mechanisms are responsible for the transfer of the patient. During the entire transfer process, the patient is lifted, transferred to the push plate assembly and retracted by the cooperation of the movement of the transport belt 119 and the push plate assembly. The process of transferring the patient from the hospital bed to the transfer vehicle is divided into three stages. The first stage is the rapid push stage. The first motor 102 drives the lead screw 104 to rotate clockwise quickly through the belt drive, and then drives the push plate assembly to move quickly to the left. At the same time, the carrier belt 119 wound on the tail drive roller 118 is unwound, and this stage ends when the push plate assembly arrives at the patient's body side; the second stage is the stage of lifting the patient, and the first motor 102 drives the leading screw 104 clockwise at a slow speed Rotate, drive the push plate assembly to move slowly to the left, and slowly stretch under the patient's body, while the third motor 116 drives the belt tail drive roller 118 to rotate clockwise. Slowly transfer to the push plate assembly, this stage ends when the whole body of the patient is transferred to the push plate assembly; the third stage is the slow reload stage, the first motor 102 drives the lead screw 104 to rotate slowly counterclockwise, driving The push plate assembly slowly retracts to the right, and at the same time, the second motor 115 drives the tape head drive roller 117 to rotate clockwise, causing the tape head drive roller 117 to wind up, and the tape tail drive roller 118 does not rotate. At this stage, the push plate assembly is completely retracted to the end End on the seat 101, so far the patient is successfully transferred from the hospital bed to the transfer vehicle. Transferring the patient from the transfer vehicle to the hospital bed is also divided into three stages: the first stage is the slow-speed loading stage, the first motor 102 drives the screw 104 to rotate slowly clockwise, driving the push plate assembly to slowly push to the left, At the same time, the tail drive roller 118 puts the belt, and this stage ends after the push plate assembly is completely sent out; the second stage is the stage of putting down the patient, and the first motor 102 drives the lead screw 104 to rotate slowly counterclockwise, driving the push plate assembly to the right at a slow speed Retract, at the same time the second motor 115 drives the tape head drive roller 117 to rotate clockwise to take in the tape, this stage ends when the patient's whole body is put down; the third stage is the fast return stage, the first motor 102 drives the lead screw 104 to rotate counterclockwise quickly , to drive the push plate assembly to quickly retract, and at the same time, the first drive roller 117 is retracted. At this stage, the push plate assembly is completely retracted. So far, the patient is successfully transferred from the transfer machine to the hospital bed.

Specifically, the bed frame is responsible for changing the shape of the transfer machine, which can switch the transfer car into a stretcher car form and a wheelchair form; the transfer mechanism is responsible for transferring the patient from the bed to the stretcher car or from the stretcher car to the bed; the height adjustment mechanism is responsible for transferring The height of the cart is adjusted to adapt to the height of the hospital bed and meet the patient's requirements; the walking mechanism is responsible for the movement requirements and position adjustment of the transfer cart; the handle assembly is only used in the form of a wheelchair, providing compulsory control means for the guardian to deal with various emergencies. In the form of a stretcher vehicle, firstly adjust the position of the transfer vehicle through the walking mechanism, then adjust the height through the height adjustment mechanism to match the height of the bed surface, and finally transport the patient through the transfer mechanism; in the wheelchair mode, the walking mechanism controls the wheelchair to walk freely, adjust the height The mechanism adjusts the height of the wheelchair to meet the requirements of the patient or guardian, and the handle assembly provides the guardian with a means of intervention.

The above-mentioned ideal embodiment according to the present invention is an inspiration. Through the above-mentioned description, relevant workers can make various changes and modifications within the scope of not departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, but must be determined according to the scope of the claims.
