Abstract

A frame assembly for a vehicle can include a main frame assembly defining a passenger compartment, and a front frame assembly. The front frame assembly can include a pair of front frame members extending upwardly, and a pair of intermediate frame members spaced apart from each other in the transverse direction of the vehicle. Each of the intermediate frame members can be connected to a respective one of the front frame members. Each of the intermediate frame members also can be connected to a cross member of the main frame assembly, and can include a bend such that each of the intermediate frame members buckles in the longitudinal direction of the vehicle if a load or kinetic energy applied to each of the intermediate frame members in the longitudinal direction of the vehicle exceeds a predetermined threshold.

First claim

What is claimed is:

1. A frame assembly for a vehicle comprising:
a main frame assembly defining a passenger compartment, and including,
a pair of side frame members extending upwardly along a vertical direction of the vehicle, and
a cross frame member extending in the transverse direction from one of the side frame members to a different one of the side frame members; and

a front frame assembly including,
a pair of front frame members, and
a pair of intermediate frame members spaced apart from each other in the transverse direction of the vehicle, each of the intermediate frame members is connected to and extends from a respective one of the front frame members, each of the intermediate frame members is also connected to the cross member, and each of the pair of intermediate frame members includes a bend such that each of the intermediate frame members buckles in the longitudinal direction of the vehicle if a load or kinetic energy applied to each of the intermediate frame members in the longitudinal direction of the vehicle exceeds a predetermined threshold;
wherein the bend of each of the intermediate frame members is oriented to be convex toward a traveling surface on which the vehicle travels.

2. The frame assembly according to claim 1 , further comprising:
a front bumper assembly connected to the front frame assembly such that the front frame assembly is located between the front bumper assembly and the main frame assembly, the front bumper assembly is configured to collapse if a load or kinetic energy is input to the front bumper assembly that exceeds a second predetermined threshold,
wherein the intermediate frame members are configured to resist deformation when subjected to a load or kinetic energy input via the front bumper assembly until the front bumper assembly initially collapses in a direction toward the main frame assembly, and the intermediate frame members are further configured to collapse in the direction toward the main frame assembly if the load or the energy input continues to be applied to the front frame members via the front bumper assembly after the front bumper assembly initially collapses.

3. The frame assembly according to claim 1 , wherein
the front frame assembly further includes a pair of lower frame members connected to and extending from the main frame assembly in the longitudinal direction of the vehicle,
each of the front frame members is connected to and extends upwardly from a respective one of the lower frame members, and
the bend of each of the intermediate frame members is oriented to be convex toward a respective one of the lower frame members.

4. The frame assembly according to claim 1 , wherein the bend of each of the intermediate frame members includes a concave portion and a tuning hole in the concave portion.

5. The frame assembly according to claim 4 , wherein
the front frame assembly further includes a pair of lower frame members connected to and extending from the main frame assembly in the longitudinal direction of the vehicle,
each of the front frame members is connected to and extends upwardly from a respective one of the lower frame members, and
each of the intermediate frame members includes a bottom portion that is a portion of the intermediate frame member that is closest to a respective one of the lower frame members in the vertical direction of the vehicle, and a drain hole is located in the bottom portion.

6. The frame assembly according to claim 1 , wherein each of the intermediate frame members is a hollow tube.

7. The frame assembly according to claim 1 , wherein
the front frame assembly further includes:
a pair of lower frame members connected to and extending from the main frame assembly in the longitudinal direction of the vehicle, and
a pair of first front frame members, each of the first front frame members is connected to and extends upwardly from a respective one of the lower frame members,

each of the front frame members includes a first end connected to a respective one of the lower frame members and a second end connected to a respective one of the first front frame members such that each of the front frame members extends from the respective one of the lower frame members to the respective one of the first front frame members, and
each of the intermediate frame members is connected to a respective one of the front frame members at a location that is between the first end and the second end.

8. The frame assembly according to claim 7 , wherein the location on the respective one of the frame members is closer to the second end than to the first end.

9. The frame assembly according to claim 1 , wherein each of the intermediate frame members is welded to the cross member and the respective one of the front frame members.

10. The frame assembly according to claim 1 , wherein each of the intermediate frame members includes a pair of straight portions and the bend is located between the straight portions.

11. The frame assembly according to claim 1 , further comprising:
a wire harness extending from the cross member to the front frame members, and the wire harness is connected to at least one of the intermediate frame members.

12. The frame assembly according to claim 11 , wherein each of the intermediate frame members includes a clip hole adjacent to the bend, and the wire harness includes a clip that is mounted in the clip hole.

13. A vehicle comprising:
a main frame assembly defining a passenger compartment of the vehicle, and including,
a pair of main frame members extending in a longitudinal direction of the vehicle, and spaced apart in a transverse direction of the vehicle,
a pair of side frame members, each of the side frame members is connected to and extends upwardly along a vertical direction of the vehicle from a front end portion of a respective one of each of the main frame members, and
a cross frame member extending in the transverse direction of the vehicle from one of the side frame members to a different one of the side frame members;

a rear frame assembly connected to and extending from a rear end portion of the main frame members in a longitudinal direction of the vehicle, the rear frame assembly is configured to mount a rear suspension and wheel assembly; and
a front frame assembly connected to and extending from a front end portion of the main frame assembly of the vehicle such that the main frame assembly extends between the front frame assembly and the rear frame assembly in a longitudinal direction of the vehicle, the front frame assembly is configured to mount a front suspension and wheel assembly, the front frame assembly including,
a pair of lower frame members connected to the main frame assembly, the pair of lower frame members extending from the main frame assembly in the longitudinal direction of the vehicle, and the lower frame members are spaced apart from each other in the transverse direction of the vehicle,
a pair of front frame members, each of the front frame members is connected to and extends upwardly from a respective one of the lower frame members, and
a pair of intermediate frame members spaced apart from each other in the transverse direction of the vehicle, each of the intermediate frame members is connected to and extends from a respective one of the front frame members, each of the intermediate frame members is also connected to the cross member, and each of the pair of intermediate frame members includes a bend such that each of the intermediate frame members buckles in the longitudinal direction of the vehicle if a load or kinetic energy applied to each of the intermediate frame members in the longitudinal
