Abstract
The present invention relates to an electric vehicle body capable of minimizing the intrusion of a collision load into a passenger space and a battery space during a front-end or rear-end collision, and comprises: a front side member having one side coupled to a front bumper beam, and the other side branching off to include a first branch part and a second branch part; a first front cross member coupled to the first branch part and the second branch part; a side seal coupled to the second branch part; a front subframe coupled to the front side member; and a battery case, which includes a reinforcing member extended in the longitudinal direction of the vehicle body and is coupled to the side seal and the first front cross member.
Claims20
An electric vehicle body, comprising:
- a front side member having one side coupled to a front bumper beam, and the other side branching off to include a first branch portion and a second branch portion;
- a first front cross member extended in a width direction of a vehicle body, and coupled to the first branch portion and the second branch portion;
- a side sill extended in a longitudinal direction of the vehicle body, and coupled to the second branch portion;
- a front subframe coupled to the front side member;
- and
- a battery case, which includes a reinforcing member extended in the longitudinal direction of the vehicle body, and is coupled to the first front cross member and the side sill,
- wherein a coupling position P of the first branch portion and the first front cross member and a first coupling position of the first branch portion and the front subframe overlaps with an imaginary cross-section formed by extending a cross-section of the reinforcing member in the longitudinal direction of the vehicle body.
An electric vehicle body, comprising:
- a rear side member having one side coupled to a rear bumper beam;
- a first rear cross member extended in a width direction of a vehicle body, and coupled to the rear side member;
- a side sill extended in a longitudinal direction of the vehicle body, and coupled to the rear side member;
- a rear subframe having one side coupled to the rear side member and the other side coupled to the first rear cross member;
- and
- a battery case, which includes a reinforcing member extended in the longitudinal direction of the vehicle body, and is coupled to the first rear cross member and the side sill,
- wherein a fourth coupling position of the rear subframe and the first rear cross member overlaps with an imaginary cross-section formed by extending a cross-section of the reinforcing member in the longitudinal direction of the vehicle body.
