The transmission gear 16, the drive gear 14, the transmission gear 16, and the translation gear 15 are all rotatably mounted on the outside of the conveyor frame 23.

[0028] The drive motor 13 drives the drive gear 14 to rotate, the transmission gear 16 rotates with the drive gear 14, and the translation gear 15 rotates coaxially. Therefore, the conveyor belt 3 translates along the translation rack 17. At the same time, the transmission gear 18 meshing on the upper side of the transmission gear 16 also rotates, driving the transmission belt 3 to rotate around the two transmission rollers, thereby transferring the patient to the hospital bed or operating table.

[0029] To ensure stable translation of the conveyor belt 3, a guide assembly is provided between the conveyor frame 23 and the bed plate 4. The guide assembly includes a linear guide rail 19 and a sliding block 20.

When the conveyor belt 3 translates, the sliding block 20 restricts the conveyor belt 3 to translate only along the linear guide rail 19.

[0030] like Figures 4-6 As shown, the transmission belt 3 is wound around two conveyor rollers. When the patient lies on the transmission belt 3, gravity will press the transmission belt 3 downward, which may affect the translation and operation of the transmission belt 3. Therefore, the transmission belt 3 is equipped with a tensioning component to adjust the tension of the transmission belt 3.

[0031] Specifically, a tension roller 21 is provided on one side of any conveyor roller, and two elongated holes 24 are provided on both sides of the conveyor frame 23. The two elongated holes 24 are inclined, and the side of the elongated hole 24 closer to the tension roller 21 is set higher.

After the patient is on the conveyor belt 3, the tensioning bolt 22 is rotated to lift the tension roller 21, and the tension roller 21 pushes the conveyor belt 3 to be tightened.

[0032] In the embodiment, two driving motors 13 are arranged on both sides of the conveying belt 3, two sets of translation gears 15, translation racks 17 and transmission assemblies are symmetrically arranged on both sides of the conveying belt 3, a synchronous shaft 25 is connected between the translation gears 15 on both sides of the conveying belt 3, the two translation gears 15 and the synchronous shaft 25 are coaxially arranged, the two driving motors 13 work synchronously, the synchronous shaft 25 ensures that the two translation gears 15 rotate synchronously, and the two driving motors 13 are forced to work synchronously, so that the conveying belt 3 runs stably.

[0033] In the embodiment, a booster wheel 10 is arranged at the central position of the lower side of the chassis 8, and the booster wheel 10 is swingably installed on the lower side of the chassis 8. Specifically, the wheel frame of the booster wheel 10 is installed on a swing frame, the swing frame is swingably installed on a mounting frame, the mounting frame is installed on the lower side of the chassis 8, the swing frame is connected with a linear motor, the linear motor drives the swing frame to realize the folding and unfolding of the booster wheel 10, and the specific structure of the booster wheel 10 can refer to the Chinese utility model patent with the application number 202321888691.4, which will not be repeated here.

[0034] One end of the bed plate 4 is provided with a fixed handrail 1, and the other end is provided with a driving handrail 11. A shift switch 12 for switching the rotating direction of the booster wheel 10 is arranged on the surface of the driving handrail 11. One end of the driving handrail 11 is a handle for driving the booster wheel 10 to rotate.

[0035] A guardrail is arranged on both sides of the bed plate 4. An infusion stand 5 is arranged on the bed plate 4. A switch panel 6 is arranged on the side plate of the bed plate 4. A control system of the medical automatic transfer vehicle is arranged in the bed plate 4.

The switch panel 6 includes a main switch, a charging port for connecting an external charger and a display screen for displaying the battery capacity. The display screen is connected with the main controller. The medical automatic transfer vehicle uses a battery as power. The battery can be placed at any position of the automatic transfer bed, such as the chassis 8.

[0036] In use, when the patient lies on the conveying belt 3, the tension of the conveying belt 3 is adjusted through the tensioning bolt 22. The medical staff pushes the handrail to transfer the patient to one side of the hospital bed or operating bed. The driving motor 13 works to drive the translation gear 15 to move along the translation rack 17, so that the conveying belt 3 translates to the hospital bed or operating bed. At the same time, the transmission gear 18 drives the transmission roller to rotate, so that the conveying belt 3 itself rotates around the two transmission rollers, and the patient is transferred from the conveying belt 3 to the hospital bed or operating bed. The driving motor 13 works to drive the translation and transmission of the conveying belt 3, which is more convenient, saves power resources, reduces labor intensity and waste of human resources, and improves the reliability of use.
