Alternatively, the outer reinforcement plate overlaps the air chamber lower plate 3, and the outer reinforcement plate overlaps the outer reinforcement beam plate 1. The upper side edge part of the external reinforcing plate is lapped on the air chamber lower plate 3, the lower side edge part of the external reinforcing plate is lapped on the external reinforcing beam plate 1, the external reinforcing plate can be connected with the air chamber lower plate 3 and the external reinforcing beam plate 1 in a welding mode, and of course, in other embodiments, modes such as bonding, buckling connection and screwing can also be adopted.

Wherein the air chamber lower plate 3 includes a horizontal portion, and the external reinforcement plate is lapped on a lower side of the horizontal portion of the air chamber lower plate 3. Referring to fig. 2 and 3, the air chamber lower plate 3 horizontally protrudes outward with respect to the dash panel 5, and the external reinforcement plate is attached to the lower surface of the horizontal portion, wherein the attachment means may be a welding connection, but of course, in other embodiments, an adhesive means, a snap connection, a screw connection, or the like may be used.

Specifically, the outer surface of the outer reinforcement panel is lapped on the inner surface of the outer reinforcing beam panel 1, and the outer reinforcement panel is sandwiched between the outer reinforcing beam panel 1 and the dash panel 5. Referring to fig. 2 and 3, the outer reinforcement plates (i.e., the first and second outer reinforcement plates 2 and 6) are sandwiched between the cowl panel 5 and the outer reinforcement beam panel 1, the lower edge portions of the outer reinforcement plates overlapping on the outer surface of the cowl panel 5, and the outer reinforcement beam panel 1 overlapping on the outer surface of the lower edge portions of the outer reinforcement plates.
