Specifically, as shown in fig. 6, the suction port 3222 extends in the front-rear direction on the suction surface 321.

In other embodiments, the suction ports 3222 are multiple and spaced along the length of the track 21, and each suction port 3222 may cover 4 to 8 suction through grooves 211. Specifically, each suction port 3222 can simultaneously correspond to 4-8 suction through grooves 211, i.e., cover 4-8 suction through grooves 211. For example, each suction port 3222 can communicate with 4, 5, 6, 7, or 8 suction through slots 211. Therefore, the adsorption through grooves 211 are communicated with the suction cavity 322, so that the adsorption area of the crawler belt 21 is increased, and the adsorption force of the automobile cleaning robot on the surface to be cleaned is improved.

In some embodiments, the adsorption apparatus further includes a suction box fixing part 33, the suction box fixing part 33 is fixed on the machine body 1, a suction passage 331 is provided in the suction box fixing part 33, the suction passage 331 has a suction inlet 3311 and a suction outlet 3312, the suction blower communicates with the suction outlet 3312, the suction box fixing part 33 is provided with a slide groove in which the suction inlet 3311 is provided, the suction box 32 has a slide rail 323, and the slide rail 323 is slidably fitted.

The suction device cooperates with the caterpillar 21 so that the automobile cleaning robot can be sucked on the surface to be cleaned, and in order to improve the traveling performance of the automobile cleaning robot, a crank mechanism 5 is added between the suction box 32 and the driving assembly 22.

Specifically, the suction inlet 3311 of the suction box fixing member 33 is elongated, and the outlet 3221 of the suction box 32 is also elongated, so that the suction inlet 3311 and the outlet 3221 slide relative to each other while the suction box 32 and the suction box fixing member 33 slide relative to each other, but are always in communication with each other. For example, the suction inlet 3311 is configured as a plurality of small holes arranged at intervals so as to be always in communication with a part of the plurality of small holes when the suction box 32 is moved. Thus, the suction box fixing part 33 can always communicate the suction box 32 and the vacuum source 31 through the suction passage 331 during the operation of the automobile cleaning robot, that is, the vacuum source 31 can communicate the suction through groove 211 through the suction box 32.
