Vehicle body structure
A vehicle body structure includes a dashboard extending in a vehicle width direction and defining a cabin and a power compartment in front of the cabin; a power unit arranged in the power compartment; a floor panel extending rearward in the cabin from the dashboard; and a dash crossmember projected forward from the dashboard and extending in the vehicle width direction. The dash crossmember has a first portion at least partially overlapping the power unit in a front view; and a second portion extending outward in the vehicle width direction from the first portion. A compressive strength of the first portion is lower than a compressive strength of the second portion.
1. A vehicle body structure comprising:
a dashboard that extends in a vehicle width direction and defines a cabin and a power compartment in front of the cabin;
a power unit arranged in the power compartment;
a floor panel that extends rearward in the cabin from the dashboard; and
a dash crossmember that extends forward from a front side of the dashboard to the power compartment and extends in the vehicle width direction,
wherein the dash crossmember has a first portion that at least partially overlaps the power unit in a front view when a vehicle is seen from the front and a second portion that extends outward in the vehicle width direction from the first portion, and
wherein a compressive strength of the first portion is lower than a compressive strength of the second portion.
2. The vehicle body structure according to claim 1 ,
wherein the floor panel includes a floor tunnel that extends in a front-rear direction of the vehicle and is projected upward, and
the vehicle body structure has, in the cabin of the dashboard, a backbone structure that is joined to the dashboard and the floor tunnel, and the backbone structure has a front-end joint section that is joined to the dashboard at an overlapping position with the second portion in the front view.
3. The vehicle body structure according to claim 2 ,
wherein the backbone structure has a vulnerable section at a position corresponding to a coupled portion between a front end portion of the floor tunnel and the dashboard.
4. The vehicle body structure according to claim 3 ,
wherein the backbone structure has an upper backbone frame that at least partially overlaps the dash crossmember in the front view.
5. The vehicle body structure according to claim 2 ,
wherein the backbone structure has an upper backbone frame that at least partially overlaps the dash crossmember in the front view.
6. The vehicle body structure according to claim 1 , wherein a length in the vehicle width direction of the second portion is greater than a length in the vehicle width direction of the power unit located in front of the second portion.
7. The vehicle body structure according to claim 6 , wherein in the front view, a lateral width of the power unit fits into a lateral width area of the second portion.
