ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a vehicle body structure, more particularly to a vehicle body with U-shaped strip portions.
2. Description of the Related Art
Referring to
FIGS. 1 and 2
, a conventional car door
100
is shown to include an outer wall
11
, an inner wall

SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a vehicle body structure that has improved resistance to external forces.
According to the present invention, a vehicle body structure comprises:
an outer wall;
an inner wall; and
a reinforcing unit disposed between the outer and inner walls, the reinforcing unit including
an intermediate plate disposed between the outer and inner walls, and
a plurality of reinforcing members, each of which has a first U-shaped strip portion mounted fixedly between the inner wall and the intermediate plate, and a second U-shaped strip portion mounted fixedly between the outer wall and the intermediate plate, each of the first U-shaped strip portions having two ends connected fixedly to the intermediate plate, and a bent portion connected fixedly to the inner wall, each of the second U-shaped strip portions having two ends connected fixedly to the intermediate plate, and a bent portion connected fixedly to the outer wall.
