Abstract

A vehicle chassis is provided. The vehicle chassis may comprise one or more vehicle chassis modules or chassis substructures that are formed from a plurality of customized chassis nodes and connecting tubes. The customized chassis nodes and connecting tubes may be formed of one or more metal and/or non-metal materials. The customized chassis nodes may be formed with connecting features to which additional vehicle panels or structures may be permanently or removeably attached. The vehicle chassis modules or chassis substructures may be interchangeably and removeably connected to provide a vehicle chassis having a set of predetermined chassis safety or performance characteristics.

First claim

What is claimed is:

1. A vehicle chassis support component comprising:
at least one vehicle tube comprising:
an inner surface defining an interior of the vehicle tube; and
a 3-D printed internal structure within the interior and extending to contact the inner surface at multiple locations distributed about a perimeter thereof for at least a section of the at least one vehicle tube;

at least one 3-D printed node comprising one or more tube mounting features coupled to a first portion of the at least one vehicle tube;
wherein at least a second portion of the at least one vehicle tube is configured to connect with one or more other nodes coupled to other structural members of a vehicle, and

at least one panel connected to one of the at least one 3-D printed node, the one or more other nodes, or the at least one vehicle tube, the at least one panel comprising a 3-D printed internal structure sandwiched between a pair of sheets;
wherein the 3-D printed internal structure of the at least one panel is exposed through a portion of the at least one panel.

2. The vehicle chassis support component of claim 1 , wherein the inner surface encloses the 3-D printed internal structure of the vehicle tube to form the inner surface of the vehicle tube.

3. The vehicle chassis support component of claim 1 , wherein the one or more other nodes comprise at least a joint member having one or more connecting features to be mated with the vehicle chassis support component.

4. The vehicle chassis support component of claim 3 , wherein the at least one joint member comprises a 3-D printed joint member.
