As shown in fig. 7 and fig. 8, the execution flow of the present invention includes two types of pushing and pulling, the pushing is the position of the patient outside the hospital bed, the medical shift cart pushes the patient to the middle of the hospital bed, the patient is close to the middle of the hospital bed, the shift position is set to about 10cm, the shift time of the shift position can be controlled by the control motor, the pulling is opposite to the pushing, the position of the patient inside the hospital bed, the shift cart moves the patient to the outside of the hospital bed, and the patient is close to the outside of the hospital bed. Both push-in and pull-out require a process involving extension and retraction of the translational plate, and first require the medical cart to remain in its initial state. The initial state means that the moving bed plate mechanism is stopped on a frame of the vehicle body, and the right side of the medical shift vehicle is an operating bed or a sickbed; the locking strip of the moving bed plate mechanism is locked at the receiving and sending side of the upper moving plate, namely the initial position Z of the locking strip.

As shown in fig. 7, the specific inward pushing flow is as follows:

(1) the medical shift trolley is in an initial state before the patient is delivered;

(2) receiving the execution action of the patient: before the moving plate extends for the first time, the locking strip driving motor rotates reversely for 2 seconds, the locking strip retreats for a preset distance (in the embodiment, the patient is corrected for deviation by 10cm, so that the locking strip is set to retreat by about 10cm), and then the locking strip driving motor is self-locked; at the moment, the movable plate driving motor rotates forwards, the upper movable plate and the lower movable plate move forwards and transversely at the same time, the movable plate is inserted between a patient and a sickbed, the patient lies on the movable plate of the shift trolley, the movable plate driving motor continues to rotate forwards until the first limiting stopper is triggered, the locking strip driving motor rotates forwards for 0.25 second, and the first limiting stopper is triggered to fail;

(3) performing actions to correct the patient position: after a patient is connected to the moving plate of the shifting vehicle, the locking strip driving motor and the moving plate driving motor rotate forwards, the locking strip and the moving plate synchronously extend out horizontally rightwards until the second limiter and the fourth limiter are triggered, and the locking strip driving motor and the moving plate driving motor stop rotating; at the moment, the locking strip and the moving plate synchronously move for 10cm, so that the patient is pushed to the middle of the medical sickbed, the patient is close to the middle of the medical sickbed, and the moving position is about 10 cm;

(4) the medical shift trolley resets and executes the following actions: after the position of the patient is corrected, the locking strip driving motor is self-locked, namely the locking strip driving motor does not rotate, the locking strip is fixed at the initial position and does not move, at the moment, the movable plate driving motor rotates reversely, the movable plate transversely retracts leftwards until the fifth limiting stopper is triggered, the movable plate driving motor stops rotating, the medical shift trolley is reset, the patient is left on a sickbed, and the whole pushing-in process is completed.

As shown in fig. 8, the specific pull-out process is as follows:

(1) the medical shift trolley is in an initial state before the patient is delivered;

(2) receiving the execution action of the patient: the locking strip driving motor is self-locked (the locking strip motor does not rotate), the movable plate driving motor rotates forwards, the upper movable plate and the lower movable plate simultaneously move forwards and transversely until the fourth limiter is triggered, the movable plate driving motor stops rotating, and the movable plate extends into a space between a patient and a sickbed;

(3) performing actions to correct the patient position: after a patient is connected to the moving plate of the shifting vehicle, the locking strip driving motor and the moving plate driving motor rotate reversely, the locking strip and the moving plate synchronously and transversely retract leftwards, and the locking strip driving motor and the moving plate driving motor stop rotating after working for 2 s; at the moment, the locking strip and the moving plate synchronously move for 10cm, so that the patient moves towards the outer side of the medical sickbed, the patient approaches to the outer side of the medical sickbed, and the moving position is about 10 cm;

(4) the medical shift trolley resets and executes the following actions: after the position of the patient is corrected, the locking strip driving motor is self-locked, namely the locking strip driving motor does not rotate, the locking strip is fixed, at the moment, the moving plate driving motor rotates reversely, the moving plate transversely retracts leftwards until the fifth limiting stopper is triggered, the moving plate driving motor stops rotating, and the moving plate finishes resetting; then, the locking strip drives the motor to rotate forwards until the second limiting stopper is triggered, the locking strip drives the motor to stop rotating, the locking strip moves rightwards by about 10cm, and the locking strip is reset; finally, the patient is left on the sickbed, and the whole outward pulling process is completed.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
