Abstract

A fuel cell vehicle is provided and includes a system frame on which a fuel cell is mounted and first and second side members extending in a first direction and facing each other in a second direction intersecting the first direction. A first fastening part fastens the system frame to each of the first and second side members. The system frame includes a first aperture formed therein in a horizontal direction. The first fastening part includes a first support bracket, including a second aperture, a first insertion hole, and a first tab portion extending from the first insertion hole in the horizontal direction, and a first bolt, including a first shank portion inserted into the first aperture, the second aperture, and the first insertion hole in the horizontal direction and a first threaded portion engaged with the first tab portion.

First claim

What is claimed is:

1. A fuel cell vehicle, comprising:
a system frame on which a fuel cell is mounted;
first and second side members extending in a first direction and facing each other in a second direction intersecting the first direction, the first direction being a traveling direction of the vehicle; and
a first fastening part configured to fasten the system frame to each of the first and second side members,
wherein the system frame includes a first aperture formed therein in a horizontal direction, and
wherein the first fastening part includes:
a first support bracket comprising a second aperture communicating with a first end portion, among two opposite end portions of the first aperture, in the horizontal direction, a first insertion hole communicating with a second end portion, among the two opposite end portions of the first aperture, in the horizontal direction, and a first tab portion extending from the first insertion hole in the horizontal direction; and
a first bolt including a first shank portion inserted into the first aperture, the second aperture, and the first insertion hole in the horizontal direction, and a first threaded portion extending from the first shank portion to be engaged with the first tab portion.

2. The fuel cell vehicle according to claim 1 , wherein the first shank portion of the first bolt overlaps a boundary between the first end portion of the first aperture and the second aperture in a vertical direction, and overlaps a boundary between the second end portion of the first aperture and the first insertion hole in the vertical direction, and wherein the vertical direction is a direction that intersects each of the first direction and the second direction.

3. The fuel cell vehicle according to claim 1 , wherein the first fastening part fastens a corner of the system frame to each of the first and second side members.

4. The fuel cell vehicle according to claim 1 , further comprising:
a first pipe nut embedded in the first support bracket, the first pipe nut having therein the first tab portion.

5. The fuel cell vehicle according to claim 1 , wherein a first one of the system frame and the first support bracket includes a first protruding portion having a convex shape and protruding toward a second one of the system frame and the first support bracket, and wherein the second one of the system frame and the first support bracket includes a recessed portion to receive the first protruding portion.

6. The fuel cell vehicle according to claim 5 , wherein the first protruding portion protrudes in the second direction.

7. The fuel cell vehicle according to claim 5 , wherein:
the system frame includes the first protruding portion,
the first support bracket includes the recessed portion,
the first aperture penetrates the first protruding portion in the horizontal direction,
the recessed portion includes:
a first inner surface facing a front surface of the first protruding portion;
a first side portion facing a first one of two opposite side surfaces of the first protruding portion and having therein a second aperture; and
a second side portion facing a second one of the two opposite side surfaces of the first protruding portion and having therein the first insertion hole and the first tab portion,
the first inner surface, the first side portion, and the second side portion form a space receiving the first protruding portion, and
the first protruding portion is disposed between the first side portion and the second side portion in the horizontal direction.

8. The fuel cell vehicle according to claim 1 , wherein the first shank portion and the first threaded portion of the first bolt have a height difference therebetween.

9. The fuel cell vehicle according to claim 8 , wherein a diameter of the first shank portion is greater than a diameter of the first threaded portion, and wherein a diameter of the first insertion hole is greater than a diameter of the first tab portion.

10. The fuel cell vehicle according to claim 9 , wherein the first bolt includes a head having a diameter greater than the diameter of the first shank portion, the head being in contact with an end portion of the second aperture.

11. A fuel cell vehicle, comprising:
a system frame on which a fuel cell is mounted;
first and second side members extending in a first direction and facing each other in a second direction intersecting the first direction, the first direction being a traveling direction of the vehicle; and
a second fastening part configured to fasten the system frame to each of the first and second side members,
wherein the system frame includes a second protruding portion protruding toward the second fastening part, and
wherein the second fastening part has a concave shape to receive at least a portion of the second protruding portion by holding a top surface and a bottom surface of the second protruding portion.

12. The fuel cell vehicle according to claim 11 , wherein the system frame includes:
a second insertion hole formed in the second protruding portion in a horizontal direction; and
a second tab portion extending from the second insertion hole in the horizontal direction, and
wherein the second fastening part includes:
a second support bracket having therein a third aperture communicating with the second insertion hole in the horizontal direction; and
a second bolt having a second shank portion, inserted into the third aperture and the second insertion hole in the horizontal direction, and a second threaded portion, engaged with the second tab portion.

13. The fuel cell vehicle according to claim 12 , further comprising:
a second pipe nut embedded in the system frame, the second pipe nut having therein the second tab portion.

14. The fuel cell vehicle according to claim 12 , wherein the second support bracket includes:
a second inner surface facing a front surface of the second protruding portion;
an upper end disposed on the second inner surface, the upper end being in contact with the top surface of the second protruding portion; and
a lower end disposed under the second inner surface, the lower end being in contact with the bottom surface of the second protruding portion,
wherein the second inner surface, the upper end, and the lower end form a space receiving the second protruding portion, and
wherein the second protruding portion is located between the upper end and the lower end in a vertical direction.

15. The fuel cell vehicle according to claim 14 , wherein:
the second inner surface of the second support bracket is in contact with a front surface of the second protruding portion,
a bottom surface of the upper end of the second support bracket is in contact with an entire area of the top surface of the second protruding portion, and
