[0008] The right mounting seat is fixed on the outer side surface of the front end of the right longitudinal beam, and the connection between the two forms an L-shaped structure;

[0009] The main bumper is fitted and fixed together with the front side surfaces of the left and right longitudinal beams to form a T-shaped structure in which the middle section of the main bumper protrudes forward and the left and right mounting seats are positioned backward, thereby increasing the power system installation space between the left and right longitudinal beams.

[0010] In some implementations, the main bumper includes:

[0011] A vertical plate, the rear side of which is fixed to the front side of the left longitudinal beam and the right longitudinal beam;

[0012] A C-shaped plate fixed to the front side of the vertical plate, the two forming a box-shaped structure;

[0013] At least one air intake pipe is embedded in the vertical plate and the C-shaped plate to increase the air intake area of ​​the power system.

[0014] In some implementations, both ends of the vertical plate extend to the front plates on the left mounting seat and the right mounting seat respectively, and the two end faces are butted and welded together; the rear side surfaces at both ends of the vertical plate are also welded to the top plate and bottom plate of the left mounting seat and the right mounting seat.

[0015] In some implementations, both ends of the C-shaped plate are gradual transition structures and extend to the front of the left mounting seat and the right mounting seat to form supporting ribs for the left mounting seat and the right mounting seat.

[0016] In some implementations, at least one inner rib plate is fixed between each end of the C-shaped plate and the vertical plate.

[0017] In some embodiments, the left and right mounting seats are integrally a box-type structure, and at least one mounting plate structure is fixed to the top surface of the left and right mounting seats for placing the cover and the cab on the left and right mounting seats behind the main bumper.

[0018] In some implementations, a gap is left between the front plates of the left mounting seat and the right mounting seat and the outer side surfaces of the corresponding longitudinal beams, and the gap is used to mount the main bumper.

[0019] In some implementations, the left mounting seat and the right mounting seat are provided with protruding structures for increasing welding points on the inner side surfaces contacting the outer side surfaces of the longitudinal beam.
