Detailed Description
As shown in fig. 1 and 3, an automobile front body structure for improving a front offset collision performance includes a front impact beam 1, a front longitudinal beam assembly 3, and a front wheel house reinforcing beam assembly 5, where the front longitudinal beam assembly 3 is located at the rear of the front impact beam 1, and the front wheel house reinforcing beam assembly 5 is located at the outer side of the front longitudinal beam assembly 3, which is the prior art. A triangular connecting plate 2 is connected between the front anti-collision beam 1 and the front end of the front longitudinal beam assembly 3, and an oblique angle is formed between the triangular connecting plate 2 and the front longitudinal beam assembly 3. The triangular connecting plate 2 is connected with the front longitudinal beam assembly 3 through welding at the side edge face on the inner side of the vehicle. And a front wheel casing extension plate assembly 4 is connected between the triangular connecting plate 2 and the front wheel casing reinforcing beam assembly 5, and the front wheel casing extension plate assembly 4 is arc-shaped.
