The operating principle of the dish delivery vehicle 20 is as follows: the battery 231 supplies power to the third motor 233 through the control box 232. When the third motor 233 is operated, the first driving wheel 2341 is driven to rotate, and the first driving wheel 2341 drives the second driving wheel 2342 to rotate in a gear transmission manner, so that the dish conveying vehicle 20 is driven to travel on the conveying track 10. The driven roller 2343, the first auxiliary roller 2344 and the second auxiliary roller 2345 play a role in keeping balance, so that the dish conveying vehicle 20 can stably walk.

In another embodiment of the present invention, as shown in fig. 5, the first transfer device 31 of the unmanned restaurant includes a fourth frame 311, a fourth motor 312, a third screw 313, a third nut 314, a third slide rail 315, a fifth slide bracket 316, a fifth connection rail 317, and a sixth connection rail 318. The fourth motor 312 is disposed on the fourth frame 311, the third lead screw 313 is connected to an output shaft of the fourth motor 312, and the third nut 314 is screwed to the third lead screw 313. The third slide rail 315 is fixedly disposed on the fourth frame 311, and the fifth sliding bracket 316 is slidably connected to the third slide rail 315. The fifth connection rail 317 and the sixth connection rail 318 are respectively and fixedly disposed at two ends of the fifth sliding support 316. The conveying track 10 is provided with a third gap 13. When the first transfer device 31 receives the dish conveying vehicle 20 from the conveying rail 10, the fifth docking rail 317 is fitted into the third notch 13, and the dish conveying vehicle 20 travels from the conveying rail 10 to the fifth docking rail 317 and stops. The fourth motor 312 drives the dish conveying vehicle 20 on the fifth docking track 317 to move to a position where the dish conveying vehicle cooperates with the first door opener 32. The sixth docking rail 318 is embedded in the third notch 13. The purpose of the above arrangement is that when the fifth docking rail 317 leaves the third notch 13, the sixth docking rail 318 replaces the fifth docking rail 317 to be embedded into the third notch 13, and the other dish conveying vehicles 20 can continue to travel on the conveying rail 10 through the sixth docking rail 318, which has the advantages of improving the dish conveying efficiency and shortening the dish conveying time.

The first transfer device 31 returns the food conveying vehicle 20 to the conveying track 10, the fourth motor 312 drives the fifth docking track 317 to reset and be embedded in the third notch 13, and the food conveying vehicle 20 travels from the fifth docking track 317 to the conveying track 10.

As shown in fig. 5, the first door opener 32 includes a cylinder 321 and a hook 322. The air cylinder 321 is fixedly arranged on the fourth frame 311, and the air cylinder 321 drives the hook 322 to move up and down. When the dish transferring cart 20 moves to one side of the first door opener 32, the hook 322 hooks the door 222, and specifically, the hook 322 hooks the door 222 through the second stopper 2221. The air cylinder 321 drives the hook 322 to move upwards to open the box door 222. When the door 222 is closed, the cylinder 321 drives the hook 322 to move downward to close the door 222.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
