Vehicle body structure
A vehicle body structure has: a front plate portion that faces in a vehicle front-rear direction; an inclined portion that obliquely descends rearward from a lower end of the front plate portion and is coupled to a floor panel making up a floor surface of a cabin; an arch-shaped portion located at outer end portions in a vehicle width direction of the front plate portion and the inclined portion and makes up a wheel arch-shaped rear portion of a tire house; a front side frame located inward of the arch-shaped portion in the vehicle width direction and extends from the front plate portion to the inclined portion in the vehicle front-rear direction; and a reinforcement panel placed over the arch-shaped portion. The reinforcement panel is disposed outward in the vehicle width direction of an innermost portion in the vehicle width direction in the arch-shaped portion.
1. A vehicle body structure comprising:
a front plate portion that faces in a vehicle front-rear direction;
an inclined portion that obliquely descends rearward from a lower end of the front plate portion and is coupled to a floor panel making up a floor surface of a cabin;
an arch-shaped portion that is located at outer end portions in a vehicle width direction of the front plate portion and the inclined portion and makes up a wheel arch-shaped rear portion of a tire house;
a front side frame that is located inward of the arch-shaped portion in the vehicle width direction and extends from the front plate portion to the inclined portion in the vehicle front-rear direction;
a reinforcement panel that is placed over the arch-shaped portion; and
a cross-member that is joined to an inner end portion of the reinforcement panel in the vehicle width direction, wherein
the reinforcement panel is disposed only in an area outward of an innermost portion of the arch-shaped portion in the vehicle width direction, and
the reinforcement panel is joined to the inclined portion with the cross-member via a ridge line joint portion that is set up along a ridge line between the arch-shaped portion and the inclined portion.
2. The vehicle body structure of claim 1 , further comprising an outrigger that is disposed on a surface on an opposite side from a surface on which the reinforcement panel is placed, in at least one of the arch-shaped portion and the inclined portion, which is rearward of the arch-shaped portion, and is joined thereto via the ridge line joint portion.
3. The vehicle body structure of claim 2 , wherein the ridge line joint portion joins the cross-member, the inclined portion, and the outrigger together.
4. The vehicle body structure of claim 1 , wherein the cross-member is joined to the front side frame.
5. A vehicle body structure comprising:
a front plate portion that faces in a vehicle front-rear direction;
an inclined portion that obliquely descends rearward from a lower end of the front plate portion and is coupled to a floor panel making up a floor surface of a cabin;
an arch-shaped portion that is located at outer end portions in a vehicle width direction of the front plate portion and the inclined portion and makes up a wheel arch-shaped rear portion of a tire house;
a front side frame that is located inward of the arch-shaped portion in the vehicle width direction and extends from the front plate portion to the inclined portion in the vehicle front-rear direction;
a reinforcement panel that is placed over the arch-shaped portion; and
an outrigger that is disposed on a surface on an opposite side from a surface on which the reinforcement panel is placed, in at least one of the arch-shaped portion and the inclined portion, which is rearward of the arch-shaped portion, and is joined thereto via a ridge line joint portion that is set up along a ridge line between the arch-shaped portion and the inclined portion,
wherein the reinforcement panel is disposed outward in the vehicle width direction of an innermost portion in the vehicle width direction in the arch-shaped portion, and wherein the reinforcement panel is laid across and over the arch-shaped portion to the inclined portion rearward of the arch-shaped portion while following shapes of the arch-shaped portion and the inclined portion, and is joined to the inclined portion via the ridge line joint portion.
6. The vehicle body structure according to claim 5 , further comprising:
a cross-member that is joined to an inner end portion of the reinforcement panel in the vehicle width direction, extends along the vehicle width direction, and is joined to the outrigger.
7. The vehicle body structure according to claim 6 , wherein
the reinforcement panel comprises:
a front-rear joint portion that is set up in a portion facing in a vehicle front-rear direction; and
a vehicle-width joint portion that is set up in a portion facing in the vehicle width direction, and
the reinforcement panel is joined to a vehicle structural body that makes up a vehicle body via the front-rear joint portion and the vehicle-width joint portion.
8. The vehicle body structure according to claim 7 , wherein
the vehicle structural body is a front pillar.
