Embodiment Construction

[0038] Below, based on Figure 1 to Figure 7 , the embodiment of the present invention will be described. In addition, the front-rear direction, the left-right direction (vehicle width direction), and the up-down direction in this specification are defined based on the occupant sitting on the driver's seat.

[0039] Such as figure 1 with figure 2 As shown, a pair of left and right side beams 11, 11 extend forward and rearward along the both sides of the floor of the compartment in the vehicle width direction, and a pair of left and right front pillars stand upright from the front ends of the pair of left and right side beams 11, 11. Bottom 12,12, from the upper end of a left and right pair of front pillar bottoms 12,12, extend back upwards with a left and right pair of front pillar tops 13,13, the upper ends of this left and right pair of front pillar tops 13,13 are aligned with the left and right sides. The front ends of the pair of roof side rails 14, 14 are connected. ...

Abstract

A front side frame has a closed section through coupling between a frame main body having a U-shaped section that opens to the outboard side and a back plate that closes the opening of the frame main body. A reinforcing frame having a U-shaped section that opens to the outboard side in a frame widened section of the front side frame is fitted to the inside of the frame main body. A vehicle-width-direction inboard wall of the reinforcing frame is coupled to a vehicle-width-direction inboard wall of the frame main body at a branch point. A portion of the vehicle-width-direction inboard wall in front of the branch point separates from the vehicle-width-direction inboard wall of the frame main body to the outboard side. The opening of the reinforcing frame is closed by the back plate in the front section of the frame widened section.

Description

technical field [0001] The present invention relates to an automobile body structure in which left and right front side frames arranged in a front-rear direction at a front portion of a vehicle body have: a frame bottom extending in a front-rear direction along a lower surface of a floor; a frame inclined portion, It extends obliquely forward from the third bending point at the front end of the frame bottom while bending outward in the vehicle width direction; the frame straight portion extends forward from the second bending point at the front end of the frame inclined portion, At the first bending point in the middle of the front-rear direction, the outer edge in the vehicle width direction is recessed toward the inner side in the vehicle width direction; Stretch forward while expanding outward. Background technique [0002] The following Patent Document 1 discloses an automobile body structure in which branch frames are extended forward and obliquely outward in the vehic...
