[0038] In the embodiment, the front lower panel 100 can be divided into three regions along the interval direction X, which can be an outer edge panel region 110, a middle panel region 120 and an outer edge panel region 110 in sequence. The thickness of one outer edge panel region 110 can be greater than the thickness of the middle panel region 120. Alternatively, the thickness of both outer edge panel regions 110 can be greater than the thickness of the middle panel region 120. Alternatively, the thickness of one outer edge panel region 110 can be less than or equal to the thickness of the middle panel region 120, and the thickness of the other outer edge panel region 110 can be greater than the thickness of the middle panel region 120. The thickness of the outer edge panel region 110 being greater than the thickness of the middle panel region 120 can be understood as the thinnest part of the outer edge panel region 110 being greater than the thickest part of the middle panel region 120, or the average thickness of the outer edge panel region 110 being greater than the average thickness of the middle panel region 120.

[0039] Through the above embodiment, the front upper panel 200 and the front lower panel 100 are separately provided, which can be easily designed and formed, and the size precision of the front upper panel 200 and the front lower panel 100 can be easily controlled. The middle panel region 120 of the front lower panel 100 is located between the two outer edge panel regions 110 along the interval direction X of the two vehicle longitudinal beams 12, and the thickness of at least one of the two outer edge panel regions 110 is greater than the thickness of the middle panel region 120, which can meet the performance requirements of the vehicle body assembly 10, reduce the production cost, and improve the size precision of each region.

That is, each outer panel region 110 has a length in the spacing direction X that is greater than a length of the middle panel region 120 in the spacing direction X. For example, each outer panel region 110 can occupy two-fifths of the total length of the front underbody panel 100 in the spacing direction X, and the middle panel region 120 can occupy one-fifth of the total length of the front underbody panel 100 in the spacing direction X.
