Abstract

A structural frame for a vehicle chassis includes transversely-oriented unitary structural members interconnecting at least three longitudinally-oriented elongated members. The use of unitary structural members and elongated members provides flexibility in assembling structural frames of differing configurations. Correspondingly, a method of assembling structural frames having transversely-oriented unitary structural members interconnecting at least three longitudinally-oriented elongated members is provided.

Claims

1. A vehicle chassis comprising:

a structural frame having

at least three longitudinally-oriented elongated members, at least one of said elongated members being vertically spaced from the other elongated members; and

a unitary structural member extending transversely and vertically between the at least three longitudinally-oriented elongated members, and attached to, and thereby interconnecting, the at least three longitudinally-oriented members; and

a body attachment interface having body connection components including at least one load-bearing body-retention coupling mounted with respect to the structural frame.

2. The vehicle chassis of claim 1, wherein the unitary structural member includes at least three cavities configured to at least partially locate the at least three longitudinally-oriented elongated members for attachment to the unitary structural member.

3. The vehicle chassis of claim 1, wherein the unitary structural member defines an open space.

4. The vehicle chassis of claim 1, further comprising at least four elongated members, and wherein the unitary structural member is attached to, and thereby interconnects, the at least four longitudinally-oriented elongated members.

5. The vehicle chassis of claim 4, further comprising:

a suspension system;

at least three wheels rotatably mounted with respect to the suspension system;

a braking system;

a steering system;

an energy conversion system; and

an energy storage system operably connected to the energy conversion system.

6. A vehicle chassis comprising:

a structural frame having

at least four longitudinally-oriented elongated members, at least one of said elongated members being vertically spaced from the other elongated members; and

a unitary structural member extending transversely and vertically between the at least four longitudinally-oriented elongated members, and attached to, and thereby interconnecting, the at least four longitudinally-oriented members;

a body attachment interface having body connection components including at least one load-bearing body-retention coupling mounted with respect to the structural frame;

a suspension system;

at least three wheels rotatably mounted with respect to the suspension system;

a braking system;

a steering system;

an energy conversion system; and

an energy storage system operably connected to the energy conversion system;

wherein the braking system, steering system, and energy conversion system are each operably connected to at least one wheel and configured to respond to non-mechanical control signals;

wherein the body connection components further include at least one control signal receiver connector mounted with respect to the structural frame and configured to convey control signals in non-mechanical form; and

wherein each of the steering system, braking system, and energy conversion system are operably connected to a control signal receiver connector.

7. The vehicle chassis of claim 6, wherein the body connection components are in a predetermined spatial relationship with one another, and sufficiently positioned, arranged, and unobstructed such that when a vehicle body having complementary components in the same predetermined spatial relationship as the body connection components is sufficiently positioned relative to the body attachment interface, each of the body connection components is adjacent to a complementary component.

8. The vehicle chassis of claim 6, wherein the structural frame includes at least eight elongated members, and wherein the unitary structural member is attached to, and thereby interconnects, the at least eight longitudinally-oriented elongated members.

9. A vehicle chassis comprising:

a structural frame having

four elongated members positioned longitudinally; and

at least two unitary structural members, each of the at least two unitary structural members having an upper cross-member portion and a lower cross-member portion, the upper and lower cross member portions connected by two vertically-oriented portions spaced a distance apart, the upper-cross member portion, lower cross member portion, and two vertically-oriented portions defining an open space configured to contain vehicle chassis hardware, and each of the at least two unitary structural members formed to have at least four cavities configured to at least partially retain the four elongated members in a rectangular arrangement relative to one another;

a body attachment interface having body connection components including at least one load-bearing body-retention coupling mounted with respect to the structural frame, and at least one control signal receiver connector configured to convey control signals in non-mechanical form;

a suspension system;

at least three wheels rotatably mounted with respect to the suspension system;

a braking system;

a steering system;

an energy conversion system; and

an energy storage system operably connected to the energy conversion system;

wherein the braking system, steering system, and energy conversion system are operably connected to at least one wheel, each operably connected to a control signal receiver connector, and each configured to respond to non-mechanical control signals.
