Abstract

A modular platform for a vehicle includes a scalable frame structure. The scalable frame structure includes a front frame portion configured to receive a front vehicle suspension, a rear frame portion configured to receive a rear vehicle suspension, and a pair of rails extending between the front frame portion and the rear frame portion along opposing sides of the frame structure. A length of the pair of rails is scalable to adjust a wheelbase of the vehicle between the front vehicle suspension and the rear vehicle suspension. A battery pack is supported on the frame structure.

First claim

What is claimed is:

1 . A modular platform for a vehicle, the modular platform comprising:
a scalable frame structure, the frame structure comprising:
a front frame portion configured to receive a front vehicle suspension, the front frame portion comprising a front frame cross-member that extends between respective first ends of the pair of rails, the front frame cross member comprising:
a first flange that extends along the length of the front frame cross-member and that is configured to support a floor panel of the vehicle at a first floor height relative to the pair of rails; and
a second flange that extends along the length of the front frame cross-member and above the first flange and that is configured to support the floor panel at a second floor height relative to the pair of rails that is above the first floor height;

a rear frame portion configured to receive a rear vehicle suspension; and
a pair of rails extending between the front frame portion and the rear frame portion along opposing sides of the frame structure, wherein each rail in the pair of rails comprises a length that is scalable to adjust a wheelbase of the vehicle between the front vehicle suspension and the rear vehicle suspension; and
a battery pack supported on the frame structure, wherein a length of the front frame cross-member is scalable to adjust a wheel track of the vehicle between a pair of wheels coupled to the front vehicle suspension.

2 . The modular platform of claim 1 , wherein:
each rail of the pair of rails comprises an extruded rail; and the extruded rail is trimmed to one of:
a first length to adjust the wheelbase of the vehicle to a first wheelbase; or
a second length that is less than the first length to adjust the wheelbase of the vehicle to a second wheelbase that is less than the first wheelbase.

3 . The modular platform of claim 2 , wherein the extruded rail comprises:
a first mounting position configured to receive one of the front frame portion or the rear frame portion when the extruded rail is trimmed to the first length; a second mounting position configured to receive the one of the front frame portion or the rear frame portion when the extruded rail is trimmed to the second length; and one or more third mounting positions configured to receive the other one of the front frame portion or the rear frame portion.

4 . The modular platform of claim 3 , wherein, when the extruded rail is trimmed to the second length, the extruded rail is trimmed between the first mounting position and the second mounting position and the first mounting position is removed from the extruded rail.

5 . The modular platform of claim 1 , wherein:
the front frame cross-member comprises an extruded cross-member; and the extruded cross-member is trimmed to one of:
a first length to adjust the wheel track to a first wheel track; or
a second length that is less than the first length to adjust the wheel track to a second wheel track that is less than the first wheel track.

6 . The modular platform of claim 1 , wherein:
the vehicle comprises a sedan or a coupe and the first flange of the front frame cross-member supports the floor panel; or the vehicle comprises an SUV and the second flange of the front frame cross-member supports the floor panel.

7 . The modular platform of claim 1 , wherein the floor panel, when supported at the front frame cross-member, extends above and along the battery pack supported on the frame structure.

8 . The modular platform of claim 1 , wherein respective lengths of the front vehicle suspension and the rear vehicle suspension are scalable to adjust a ground clearance of the vehicle between the frame structure and a ground surface.

9 . The modular platform of claim 1 , wherein the pair of rails extend along and mount to opposing sides of the battery pack to support the battery pack on the frame structure.

10 . The modular platform of claim 1 , wherein the frame structure is configured to support a body of the vehicle.

11 . The modular platform of claim 1 , wherein the battery pack is operable to electrically power a drivetrain of the vehicle.

12 . A vehicle comprising:
a scalable frame structure, the frame structure comprising:
a front frame portion configured to receive a front vehicle suspension, the front frame portion comprising a front frame cross-member that extends between respective first ends of the pair of rails, the front frame cross member comprising:
a first flange that extends along the length of the front frame cross-member and that is configured to support a floor panel of the vehicle at a first floor height relative to the pair of rails; and
a second flange that extends along the length of the front frame cross-member and above the first flange and that is configured to support the floor panel at a second floor height relative to the pair of rails that is above the first floor height;

a rear frame portion configured to receive a rear vehicle suspension; and
a pair of rails extending between the front frame portion and the rear frame portion along opposing sides of the frame structure, wherein each rail of the pair of rails comprises a length that is scalable to adjust a wheelbase of the vehicle between the front vehicle suspension and the rear vehicle suspension; and
a battery pack supported on the frame structure, the battery pack operable to electrically power a drivetrain of the vehicle, wherein a length of the front frame cross-member is scalable to adjust a wheel track of the vehicle between a pair of wheels coupled to the front vehicle suspension.

13 . The vehicle of claim 12 , wherein:
each rail of the pair of rails comprises an extruded rail; and the extruded rail is trimmed to one of:
a first length to adjust the wheelbase of the vehicle to a first wheelbase; or
a second length that is less than the first length to adjust the wheelbase of the vehicle to a second wheelbase that is less than the first wheelbase.

14 . The vehicle of claim 13 , wherein the extruded rail comprises:
a first mounting position configured to receive one of the front frame portion or the rear frame portion when the extruded rail is trimmed to the first length; a second mounting position configured to receive the one of the front frame portion or the rear frame portion when the extruded rail is trimmed to the second length; and one or more third mounting positions configured to receive the other of the front frame portion or the rear frame portion.

15 . The vehicle of claim 14 , wherein, when the extruded rail is trimmed to the second length, the extruded rail is trimmed between the first mounting position and the second mounting position and the first mounting position is removed from the extruded rail.

16 . The vehicle of claim 12 , wherein:
the front frame cross-member comprises an extruded cross-member; and the extruded cross-member is trimmed to one of:
a first length to adjust the wheel track to a first wheel track; or
a second length that is less than the first length to adjust the wheel track to a second wheel track that is less than the first wheel track.

17 . The vehicle of claim 12 , wherein:
the vehicle comprises a sedan or a coupe and the first flange of the front frame cross-member supports the floor panel; or the vehicle comprises an SUV and the second flange of the front frame cross-member supports the floor panel.

18 . The vehicle of claim 12 , wherein the floor panel, when supported on the front frame cross-member, extends above and alo
