Abstract

An embodiment is a vehicle body structure including a front body comprising a first cooling module, a middle body having a center floor panel, the center floor panel being connected to the front body, and a rear body comprising a second cooling module and a third cooling module, the second cooling module being on each of two sides of a rear portion of the rear body in a vehicle width direction, the rear body being connected to the middle body, the third cooling module being in the rear portion of the rear body.

First claim

What is claimed is:

1. A vehicle body structure comprising:
a front body comprising a first cooling module, wherein the front body includes a front side member on each of two sides of the front body in a vehicle width direction, the front side member being disposed in a vehicle body front-rear direction and the first cooling module being on a front portion of the front side member;
a middle body having a center floor panel, the center floor panel being connected to the front body; and
a rear body comprising a second cooling module and a third cooling module, the second cooling module being on each of two sides of a rear portion of the rear body in the vehicle width direction, the rear body being connected to the middle body, the third cooling module being in the rear portion of the rear body.

2. The vehicle body structure of claim 1 , further comprising a fuel cell stack disposed between both the front side members.

3. The vehicle body structure of claim 1 , wherein
the middle body includes a middle side member on each of two sides of the middle body in the vehicle width direction, the middle side member being disposed in a vehicle front-rear direction, and
the center floor panel is coupled to the middle side member, and a tunnel portion is on the center floor panel in the vehicle front-rear direction.

4. The vehicle body structure of claim 3 , wherein the rear body includes:
a rear side member on each of two sides of the rear body in the vehicle width direction, the rear side member being disposed in the vehicle front-rear direction,
a dome-shaped rear floor structure coupled to the front portion of the rear side member and connected to the center floor panel, and
a rear cross member coupled to the rear side member at the rear of the dome-shaped rear floor structure.

5. The vehicle body structure of claim 4 , wherein a partition panel is coupled to an upper portion of the dome-shaped rear floor structure to partition the middle body and the rear body from each other.

6. The vehicle body structure of claim 5 , wherein the second cooling module is on each of two sides of the dome-shaped rear floor structure in the vehicle width direction.

7. The vehicle body structure of claim 5 , wherein
the partition panel includes a bent portion bent toward the middle body from each of two sides of the rear body in the vehicle width direction, and
an air flow passage is disposed between the bent portion and a side structure, the side structure being on each of two sides of the rear body in the vehicle width direction.

8. The vehicle body structure of claim 7 , wherein
the second cooling module is in the air flow passage, and
air inlet holes connected to the air flow passage are respectively in a first rear side panel and a second rear side panel of the side structure.

9. The vehicle body structure of claim 5 , wherein the third cooling module is below the rear side member at the rear of the dome-shaped rear floor structure.

10. The vehicle body structure of claim 5 , further comprising:
at least one hydrogen tank between the partition panel and the rear cross member, and
a driving motor and an inverter below the at least one hydrogen tank.

11. The vehicle body structure of claim 5 , wherein the rear body further includes:
a part mounting unit coupled to the dome-shaped rear floor structure and the partition panel; and
at least one hydrogen tank and the second cooling module in the rear body.

12. The vehicle body structure of claim 11 , wherein the part mounting unit includes:
a lower mounting cross member coupled to the upper portion of the dome-shaped rear floor structure in the vehicle width direction and a lower portion of the partition panel, and
an upper mounting cross member coupled to an upper portion of the partition panel in the vehicle width direction.

13. The vehicle body structure of claim 4 , further comprising:
a high-voltage battery under the dome-shaped rear floor structure and under the tunnel portion on the center floor panel in the vehicle front-rear direction.

14. The vehicle body structure of claim 13 , wherein the high-voltage battery has a ‘T’ shape and is under the dome-shaped rear floor structure and the tunnel portion.

15. A vehicle body structure comprising:
a front body comprising a first cooling module;
a middle body having a center floor panel, the center floor panel being connected to the front body; and
a rear body comprising a second cooling module and a third cooling module, the second cooling module being on each of two sides of a rear portion of the rear body in a vehicle width direction, the rear body being connected to the middle body, the third cooling module being in the rear portion of the rear body;
a hydrogen charging port in a first rear side panel of a side structure on each of two sides of the rear body in the vehicle width direction; and
an electric charging port in a second rear side panel of the side structure.

16. A vehicle body structure comprising:
a front body comprising a first cooling module, a fuel cell stack, and front side members, the front side members being on each of two sides of the front body in a vehicle width direction, the front side member extending in a vehicle body front-rear direction, the vehicle body front-rear direction being perpendicular to the vehicle width direction, the first cooling module being on a front portion of the front side member, the fuel cell stack being between the front side members;
a middle body having a center floor panel, middle side members, and a tunnel portion, the middle side members being on each of two sides of the middle body in the vehicle width direction, the middle side members extending in a vehicle front-rear direction and being connected to the front side members, the center floor panel being coupled to the middle side members, the tunnel portion being on the center floor panel in the vehicle front-rear direction, the center floor panel being connected to the front body; and
a rear body comprising a second cooling module, a third cooling module, and rear side members, the rear side members being on each of two sides of the rear body in the vehicle width direction, the rear side member extending in the vehicle front-rear direction and being connected to the middle side members, the second cooling module being on each of two sides of a rear portion of the rear body in the vehicle width direction, the rear body being connected to the middle body, the third cooling module being in the rear portion of the rear body.

17. The vehicle body structure of claim 16 , wherein the rear body further comprises:
a dome-shaped rear floor structure coupled to front portions of the rear side members and connected to the center floor panel, and
a rear cross member coupled to the rear side members at the rear of the dome-shaped rear floor structure.

18. The vehicle body structure of claim 17 , wherein a partition panel is coupled to an upper portion of the dome-shaped rear floor structure.
