In addition, the dash panel 201 , the door sill reinforcement beam 244 and the front longitudinal beam 203 can also be connected to form a whole nearby through reinforcement, which is beneficial to the cooperative deformation of the formed whole and improves the strength of the vehicle.

According to some optional embodiments of the present invention, the density of the reinforcing member 1 is lower than that of the A-pillar inner panel 243, and the density of the reinforcing member 1 is smaller than that of the partition plate 240, which is beneficial to reduce the weight of the vehicle and realize the lightweight. For example, the reinforcement 1 may be foam, the A-pillar inner panel 243 may be an aluminum profile, and the partition plate 240 may be a foam cover whose density is greater than that of the reinforcement 1 .

In a word, the vehicle provided by the utility model is beneficial to improve the strength of the A-pillar, avoid the damage to the passenger compartment caused by the instability of the A-pillar, thereby enhancing the ability of the vehicle to withstand the frontal impact load and improving the safety of the vehicle. A part of the cavity can also be formed as a cavity, which is beneficial to realize the weight reduction of the vehicle.

Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, rather than limiting the scope of the present invention. It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the invention is defined by the appended claims.
