Use method of the present invention in detail below in conjunction with accompanying drawing:

Before the operation of the equipment, the patient lies on the top of the equipment. As shown in FIG. After a controller 29 receives the command to transfer the patient, it sends a lift controller 26 to the first lifting controller 26 in the first walking frame 5, the second lifting controller 34 in the second walking frame 11, and the third lifting controller 34 in the third walking frame 16. The lifting controller 42 sends a lifting command. Taking the process of the first walking support 5 as an example, the first lifting controller 26 drives the first scissor jack 27 to move, and the first support plate 6, the second support plate 12 and the second support plate The three supporting plates 17 are jacked up, so that the first driving wheel 22 and the driven wheel 10 are stretched out, and stop moving after reaching a preset height, and at the same time, the first controller 29 sends a translation command to the first driving controller 21, and the first A drive controller 21 drives the drive motor 23 to run, and the small pulley on the motor reducer 24 drives the large pulley on the first drive wheel 22 through the synchronous belt 25, and then the first drive wheel 22 drives the first walking support 5 The other three driven wheels follow the movement to realize the translation of the whole equipment;

During the operation of the equipment, the first controller 29 completes the adjustment of the running direction of the equipment by sending different speed commands to the first driving controller 21 of the first walking frame 5 and the third driving controller 40 of the third walking frame After the patient is transferred to the target device, the first controller 29 sends an action command to stop the translation according to the feedback signal, and at the same time controls the device to descend according to the lifting process described above to complete the transfer of the patient. The operation process of the third transfer assembly 3 is the same as The same as the first transfer assembly 1, the second transfer assembly 2 moves along with the four driven wheels 10 during the translation process without driving;

In addition, this equipment is a three-section foldable structure, as shown in Figure 5, the two ends of the handrail rod 31 are connected with the first support plate 6 and the third support plate 17 through the pin shaft 4, and the two ends of the second support plate 12 are also connected. Connected with the first support plate 6 and the third support plate 17, the handrail bar 31, the first support plate 6, the second support plate 12, and the third support plate 17 jointly constitute a four-bar linkage mechanism. When folding the equipment such as the transfer vehicle, the lock core 33 in the armrest bar 31 is dialed to the inside of the switch lock 32, thereby releasing the restriction on the relative rotation of the armrest bar 31 and the third support plate 17, and the folding function of the transfer car drives this The first support plate 6 of the equipment is folded towards the direction close to the second support plate 12, which drives the movement of the armrest rod 31, and then drives the rotation of the third support plate 17 through the connection of the linkage mechanism to realize the folding function, thereby realizing the sitting and lying position of the patient. At the same time, according to the characteristics of the four-bar linkage mechanism, when the equipment changes to a sitting position, the armrest bars 31 on both sides will be higher than the original state of the equipment, limiting the position of the patient and playing the role of wheelchair armrests; when the patient When it is necessary to go to the toilet and there is a toilet opening below the device, as shown in Figure 6, the first controller 29 sends instructions to the small motor controller 47, and the small motor controller 47 drives the small motor 39 to run, driving the toilet rod 38 to rotate , the toilet rod 38 drives one end of the toilet board 37 to move, and the other end of the toilet board 37 moves away from the other toilet board 37 on the slideway in the second walking support 11, so that the toilet board 37 is moved from the original The state parallel to the equipment changes to a vertical state, and the toilet opening becomes open, and equipment such as bedpans or toilets can be placed below, and the patient can go to the toilet. After completion, close the toilet opening according to the opening process .

The specific implementation above is just an example, and it is for those skilled in the art to better understand this patent, and it should not be understood as a limitation on the scope of this patent, as long as it is any equivalent change or Decoration, all fall into the scope that this patent includes.
