Abstract

A framework structure of a body-on-frame vehicle, the framework structure comprises a first framework, a second framework, and a battery. The first framework includes: a pair of left and right side rails extending in a vehicle body front-and-rear direction, a first cross-member and a second cross-member, both extending in a vehicle body left-and-right direction and linking the side rails. The second framework is structured in a rectangular shape in plan view and includes: a front cross portion and a rear cross portion that are formed in chamber shapes and extend in the vehicle body left-and-right direction, and a left side cross portion and a right side cross portion that are formed in chamber shapes and extend in the vehicle body front-and-rear direction. The battery is disposed in a cavity surrounded by the first framework and the second framework.

First claim

What is claimed is:

1. A framework structure of a body-on-frame vehicle, the framework structure comprising:
a first framework, a second framework, a battery, and a floor panel,
the first framework including:
a pair of left and right side rails extending in a vehicle body front-and-rear direction,
a first cross-member extending in a vehicle body left-and-right direction and linking the side rails, and
a second cross-member extending in the vehicle body left-and-right direction at a vehicle body rear side of the first cross-member and linking the side rails;

the second framework being structured in a rectangular shape in plan view and including:
a front cross portion and a rear cross portion that are formed in chamber shapes and extend in the vehicle body left-and-right direction, and
a left side cross portion and a right side cross portion that are formed in chamber shapes and extend in the vehicle body front-and-rear direction;
the floor panel disposed at a vehicle body upper side of the first cross-member and the second cross-member, the floor panel including an aperture portion and the second framework surrounds the aperture portion in plan view,

the battery being disposed in a cavity surrounded by the first framework and the second framework; and
the battery is accommodated in an accommodation portion that is inserted in the aperture portion, the accommodation portion including a flange that is attached to the second framework.

2. The framework structure of a body-on-frame vehicle according to claim 1 ,
wherein the front cross portion, the rear cross portion, the left side cross portion, and the right side cross portion are formed into the chamber shapes by each being joined to the floor panel.

3. A framework structure of a body-on-frame vehicle, the framework structure comprising:
a first framework, a second framework, and a battery,
the first framework including:
a pair of left and right side rails extending in a vehicle body front-and-rear direction,
a first cross-member extending in a vehicle body left-and-right direction and linking the side rails, and
a second cross-member extending in the vehicle body left-and-right direction at a vehicle body rear side of the first cross-member and linking the side rails;

the second framework being structured in a rectangular shape in plan view and including:
a front cross portion and a rear cross portion that are formed in chamber shapes and extend in the vehicle body left-and-right direction, and
a left side cross portion and a right side cross portion that are formed in chamber shapes and extend in the vehicle body front-and-rear direction;

the battery being disposed in a cavity surrounded by the first framework and the second framework,
the front cross portion and the rear cross portion are linked together, at vehicle body left-and-right direction inner sides relative to the left side cross portion and the right side cross portion, by a pair of left and right braces that extend in the vehicle body front-and-rear direction, and
a gutter portion that extends in the vehicle body front-and-rear direction is formed at each of the left and right braces.

4. The framework structure of a body-on-frame vehicle according to claim 3 , wherein seat mounting portions that are configured to mount a seat are provided at the pair of left and right braces.

5. The framework structure of a body-on-frame vehicle according to claim 4 , wherein:
the gutter portions of the left and right braces are each formed by a floor face and side faces, and
position regulation portions that regulate positions of the seat mounting portions in the vehicle body front-and-rear direction are formed at the side faces.
