A conforming plate 3 is also provided on the deflector body on the air intake side, and the conforming plate 3 is consistent in shape with the side enclosure of the cab. After assembly, the overall shape can be more coordinated and beautiful.

[0029] like Figure 1 , 2 As shown, the air intake windows 1 are arranged in an array in a staggered manner in the air intake area. Figure 4 As shown, the air intake window 1 is hexagonal, and each air intake window 1 is evenly provided with a number of grille holes 11. The grille holes 11 are specifically regular hexagons that are closely and evenly distributed. Adjacent grille holes 11 are separated by bars 12, and the width B of the bars 12 is 2-2.5 mm and the length L is 3.5-5 mm. The air intake window 1 and the bars 12 are both integrally injection molded on the deflector body. The overall structural strength of the deflector body can be improved, the amplitude of the deflector body caused by the vibration of the whole vehicle can be reduced, and the air intake performance can be ensured; the integral molding can also save assembly procedures, assembly costs and material costs. The hexagonal air intake windows 1 and grille holes 11 can make the structure more compact and the opening area larger, so as to obtain a larger air intake area and better air intake performance while having a neat and coordinated appearance.

[0030] like Figure 1 , 2 As shown, the blind windows 2 are arranged in an array in an interlaced manner in the upper air intake blind area, and have the same shape as the air intake windows 1. The blind windows 2 are closed windows that are not penetrated, and their purpose is not to pass the airflow, but to ensure the layout of the guide plate grille window is beautiful and coordinated with the overall effect after assembly with the side wall of the cab.
