Vehicle floor structure

A vehicle floor structure, comprising:

• a center floor panel;
• a tunnel extending along a central longitudinal axis of the center floor panel, and having a tunnel cavity;
• a pair of first lower crossmembers attached to a bottom surface of the center floor panel, being symmetrical to each other with respect to the tunnel, and being adjacent to a front of the tunnel;
• a pair of second lower crossmembers attached to the bottom surface of the center floor panel, being symmetrical to each other with respect to the tunnel, and being adjacent to a rear of the tunnel;
• and
• a pair of lower longitudinal members attached to the bottom surface of the center floor panel, and disposed on both edges of the tunnel, respectively;
• a hydrogen tank located in the tunnel cavity of the tunnel;
• a tank support frame configured to support the hydrogen tank so that the hydrogen tank is held in the tunnel cavity, wherein the tank support frame comprises:
• a plurality of tank-side transversal members extending in a width direction of the hydrogen tank and extending in a width direction of the tunnel to connect the pair of lower longitudinal members, wherein at least one tank-side transversal member among the plurality of tank-side transversal members is aligned with and connected to the pair of first lower crossmembers along a width direction of a vehicle;
• and
• a tank-side longitudinal member extending in a longitudinal direction of the hydrogen tank;
• wherein the pair of first lower crossmembers, the pair of second lower crossmembers, and the pair of lower longitudinal members define a pair of cavities;
• and
• wherein the pair of cavities are symmetrical to each other with respect to the tunnel.

A vehicle comprising:

• a vehicle body;
• a center floor panel disposed at a bottom of the vehicle body;
• a rear floor panel disposed at the bottom the vehicle body and behind the center floor panel in a front-to-back direction of the vehicle body;
• a tunnel extending along a central longitudinal axis of the center floor panel, and having a tunnel cavity;
• a hydrogen tank located in the tunnel cavity of the tunnel;
• a tank support frame configured to support the hydrogen tank so that the hydrogen tank is held in the tunnel cavity;
• and
• a pair of lower longitudinal members attached to a bottom surface of the center floor panel, and disposed on both edges of the tunnel, respectively,
• wherein the tank support frame includes a plurality of tank-side transversal members extending in a width direction of the hydrogen tank, and a tank-side longitudinal member extending in a longitudinal direction of the hydrogen tank, and
• wherein the plurality of tank-side transversal members extend in a width direction of the tunnel to connect the pair of lower longitudinal members.
