Vehicle body structure
A vehicle body structure includes: a pair of front side frames disposed on a front side of a vehicle to be in parallel with each other along a vehicle front-rear direction; lower members and gussets (load receiving portions) disposed at front ends in the vehicle front-rear direction of the front side frames so as to extend outward in a vehicle width direction; front wheels disposed outward in the vehicle width direction of the front side frames; and right and left side sills extending in the vehicle front-rear direction. Vehicle-width-direction outer end portions of the load receiving portions are positioned outward in the vehicle width direction of vehicle-width-direction inner end portions of the front wheels, and vehicle-width-direction outer end portions of the front wheels are positioned outward in the vehicle width direction of vehicle-width-direction inner end portions of front ends in the vehicle front-rear direction of the side sills.
1. A vehicle body structure comprising:
a pair of front side frames disposed on a front side of a vehicle to be in parallel with each other along a vehicle front-rear direction;
load receiving portions disposed at front ends in the vehicle front-rear direction of the respective front side frames so as to extend outward in a vehicle width direction;
front wheels disposed outward in the vehicle width direction of the respective front side frames; and
a pair of right and left side sills disposed rearward in the vehicle front-rear direction of the respective front wheels so as to extend in the vehicle front-rear direction, wherein
vehicle-width-direction outer end portions of the load receiving portions are positioned outward in the vehicle width direction of vehicle-width-direction inner end portions of the respective front wheels,
vehicle-width-direction outer end portions of the front wheels are positioned outward in the vehicle width direction of vehicle-width-direction inner end portions of front ends in the vehicle front-rear direction of the respective side sills,
the load receiving portions are a pair of right and left lower members, and
each lower member has an L shape in front view, extends upward from a front end in the vehicle front-rear direction of the corresponding front side frame and then outward in the vehicle width direction, and is bonded to a front end in the vehicle front-rear direction of an upper member extending forward from a front pillar.
2. The vehicle body structure according to claim 1 , wherein
the load receiving portions are the pair of right and left lower members and gussets bonded to inner walls of the respective front side frames.
3. The vehicle body structure according to claim 1 , further comprising:
a tunnel cross member extending linearly along the vehicle width direction;
a pair of right and left second outriggers extending obliquely rearward linearly from rear end portions in the vehicle front-rear direction of the respective front side frames to inner sides in the vehicle width direction of the respective side sills; and
a pair of right and left first outriggers disposed forward in the vehicle front-rear direction of the second outriggers, wherein
front end portions in the vehicle front-rear direction of the second outriggers are coupled to the rear end portions in the vehicle front-rear direction of the front side frames, and rear end portions in the vehicle front-rear direction of the second outriggers are coupled to inner walls in the vehicle width direction of the side sills, and
the tunnel cross member, the pair of right and left second outriggers, and the pair of right and left first outriggers are disposed between, along the vehicle width direction, front end portions in the vehicle front-rear direction of the pair of right and left side sills, and connect the front end portions in the vehicle front-rear direction of the pair of right and left side sills.
4. The vehicle body structure according to claim 3 , wherein
a pair of right and left tunnel frames extending linearly are disposed at connecting portions between a floor tunnel extending in the vehicle front-rear direction and floor panels extending in the vehicle front-rear direction, and
front end portions in the vehicle front-rear direction of the tunnel frames are positioned on top of the tunnel cross member and fixed to the tunnel cross member.
5. The vehicle body structure according to claim 4 , wherein
the tunnel cross member has a hat-shaped cross section perpendicular to an axis of the tunnel cross member,
the tunnel frames each have an L-shaped cross section perpendicular to an axis of the tunnel frame,
a front flange in the vehicle front-rear direction of the tunnel cross member extends obliquely upward along a dash lower panel and is fixed to the tunnel frames, and
a rear flange in the vehicle front-rear direction of the tunnel cross member is fixed to the tunnel frames.
6. The vehicle body structure according to claim 3 , wherein
dash cross members extending in parallel in a vehicle up-down direction with the second outriggers are disposed above the second outriggers in the vehicle up-down direction, and
the dash cross members are fixed to a dash lower panel.
7. The vehicle body structure according to claim 6 , wherein
an outer flange in the vehicle width direction of each second outrigger and a lower flange in the vehicle up-down direction of a corresponding one of the dash cross members are overlapped in the vehicle width direction via the dash lower panel, and both the outer flange in the vehicle width direction of the second outrigger and the lower flange in the vehicle up-down direction of the dash cross member are fixed to the dash lower panel.
8. The vehicle body structure according to claim 5 , wherein
the floor panels each have beads extending in the vehicle front-rear direction, and
the dash lower panel has beads extending radially from the rear end portions in the vehicle front-rear direction of the front side frames toward front end portions in the vehicle front-rear direction of the floor panels.
