[0018] Compared with the prior art, the beneficial effects of the present invention are:

The macro-flow guiding structures 14 capture surface water, so that the water is discharged from the first flow channel 141 to the liquid discharge structure 4 and then discharged outside the vehicle, which can prevent water accumulation inside. The first flow channel 141 adopts a top opening design, which is convenient for cleaning with a high-pressure water gun.

[0042] Multiple liquid discharge structures 4 are fixedly connected to the top surface of the lower plate 2 at the position directly below the ends of multiple macroscopic flow guiding structures 14.

[0054] The drainage method of this invention is as follows: Liquid falls onto the surface of the upper plate structure 1, such as rainwater, washing water, and water carried by the goods. Then, the liquid is quickly captured by the depressions of the micro-guiding texture 132 and the micro-gathering texture 144. The liquid is initially gathered by the surface tension. Through the micro-network connected in the micro-gathering texture 144, a small stream of water is guided to the first guide channel 141. Under the action of gravity or the guiding action of the piezoelectric fan 46, the liquid flows towards the liquid discharge structure 4 and finally enters the drainage chamber 41. Meanwhile, some water at the joint of the sheet metal plate 131 and the joint between the sheet metal unit 13 and the macro-guiding structure 14 seeps into the joint guide structure 15. Similarly, these seeping liquids enter the drainage chamber 41 under the guiding action of gravity or the piezoelectric fan 46. Finally, these liquids are discharged outside the vehicle through the discharge bend 44. This invention uses a macroscopic flow guiding structure 14 to capture surface water, and microscopic flow guiding textures 132 and microscopic gathering textures 144 to capture liquid. Surface tension is used to gather the liquid, and the interconnected microscopic network in the textures allows the water to drain from the first flow guiding channel 141 into the liquid discharge structure 4, and then out of the vehicle, thus preventing internal water accumulation. A joint flow guiding structure 15 is also provided to address water seepage at joints. The second flow guiding channel 151 is located at the joint between the sheet metal unit 13 and the macroscopic flow guiding structure 14, while the branch flow guiding chamber 152 is located at the joint of the sheet metal plate 131. This allows water seepage at the joint to directly enter the second flow guiding channel 151 or the branch flow guiding chamber 152, ultimately converging at the second flow guiding channel 151 and draining from the liquid discharge structure 4, preventing internal frame corrosion caused by water seepage.
