Abstract

A vehicle having an exoskeleton exterior panel that provides crash resistance is described. The exterior panel may be formed from a monolithic metal sheet and attached to an exterior portion of the vehicle frame, and the exterior panel does not comprise an additional support structure. At least one component may be directly attached to the exterior panel, and the exterior panel may bear the load of the at least one component. Methods of manufacturing the vehicle are also described.

First claim

What is claimed is:

1. A vehicle, comprising:
an internal structural vehicle framework comprising an exterior portion;
an exterior panel formed from a monolithic metal sheet and mounted to the exterior portion of the internal structural vehicle framework directly through a joint, wherein the exterior panel acts as a support structure for at least one component; and
the at least one component directly attached to the exterior panel,
wherein the exterior panel is a passenger door panel,
wherein the exterior panel bears the load of the at least one component, and
wherein the exterior panel does not consist of an additional support structure selected from the group consisting of an additional metal panel, a support beam, a reinforcement, an anti-intrusion bar, and combinations thereof.

2. The vehicle of claim 1 , wherein the monolithic metal sheet comprises a metal selected from the group consisting of steel and aluminum.

3. The vehicle of claim 1 , wherein the at least one component is selected from the group consisting of a motor, an interior trim panel, and combinations thereof.

4. The vehicle of claim 1 , wherein the exterior panel provides side impact protection for the vehicle.

5. The vehicle of claim 1 , wherein an exterior surface of the exterior panel does not comprise paint.

6. The vehicle of claim 1 , further comprising an electric motor.

7. A method of manufacturing an automotive vehicle, comprising:
providing a monolithic metal sheet, wherein the monolithic metal sheet is manufactured comprising the steps of:
providing an initial monolithic metal sheet;
cutting the initial monolithic metal sheet to form a cut monolithic metal sheet; and
shaping the cut monolithic metal sheet to form the monolithic metal sheet;

attaching at least one component directly to the monolithic metal sheet to form an exterior panel, wherein the monolithic metal sheet bears the load of the at least one component thereby acting as a support structure; and
mounting the exterior panel to an exterior portion of an internal structural vehicle framework directly through a joint;
wherein the method does not consist of attaching an additional support structure to the exterior panel, the additional support structure selected from the group consisting of an additional metal panel, a support beam, a reinforcement, an anti-intrusion bar, and combinations thereof, and
wherein the exterior panel is configured to define a passenger compartment of the vehicle.

8. The method of claim 7 , wherein the initial monolithic metal sheet is a rolled metal sheet.

9. The method of claim 7 , wherein the method does not comprise heat treating the monolithic metal sheet.

10. The method of claim 7 , wherein the method does not consist of joining the exterior panel to another metal panel.

11. The method of claim 7 , wherein cutting is performed by laser cutting.

12. The vehicle of claim 1 , wherein the joint comprises a hinge, a latch, or a bolt.

13. The vehicle of claim 1 , wherein the exterior panel is mounted to a pillar of the exterior portion of the internal structural vehicle framework at one end, such that the exterior panel is configured to rotate about the pillar.

14. The vehicle of claim 1 , wherein the internal structural vehicle framework comprises a pillar assembly, and wherein the pillar assembly consists essentially of an interior support structure and a pillar of the exterior portion of the internal structural vehicle framework.

15. The vehicle of claim 1 , wherein the internal structural vehicle framework is a unibody internal structural vehicle framework.

16. The method of claim 7 , wherein the joint comprises a hinge, a latch or a bolt.

17. The method of claim 7 , wherein mounting the exterior panel comprises mounting one end of the exterior panel to a pillar of the exterior portion of the internal structural vehicle framework, such that the exterior panel is configured to rotate about the pillar.

18. A vehicle, comprising:
an internal structural vehicle framework comprising an exterior portion;
an exterior panel formed from a monolithic metal sheet and mounted to the exterior portion of the internal structural vehicle framework directly through a joint, wherein the exterior panel acts as a support structure for at least one component; and
the at least one component directly attached to the exterior panel,
wherein the exterior panel bears the load of the at least one component,
wherein the exterior panel does not consist of an additional support structure selected from the group consisting of an additional metal panel, a support beam, a reinforcement, an anti-intrusion bar, and combinations thereof, and
wherein the internal structural vehicle framework is a unibody internal structural vehicle framework.

19. The vehicle of claim 18 , wherein the exterior panel is a door panel.

20. The vehicle of claim 18 , wherein the exterior panel is configured to define a passenger compartment of the vehicle.
