Abstract

In one embodiment, the invention is a frame for a ride-on vehicle having at least one front wheel, at least one rear wheel, and a plurality of substantially similar battery packs. The frame defines a central plane and includes a front end located adjacent to the front wheel(s), a rear end located adjacent to the rear wheel(s), and a lattice structure that extends substantially between the front end and the rear end. The lattice structure includes a first portion that includes battery pack mounts that secure a first subset of the battery packs arranged in two layers, and includes a second portion that includes battery pack mounts that secure a second subset of the batter packs arranged in a single layer. The lattice structure also defines a truss that mechanically couples the front wheel(s) to the rear wheel(s).

Claims

1. A frame for a ride-on vehicle having at least one front wheel, at least one rear wheel, and a plurality of substantially similar battery packs, comprising:

a frame defining a central plane and including a front end located adjacent to the front wheel(s), a rear end located adjacent to the rear wheel(s), and a lattice structure that extends substantially between the front end and the rear end, wherein the lattice structure includes a first portion that includes battery pack mounts that secure a first subset of the battery packs arranged in two layers, wherein the lattice structure includes a second portion that includes battery pack mounts that secure a second subset of the batter packs arranged in a single layer, and wherein the lattice structure defines a truss that mechanically couples the front wheel(s) to the rear wheel(s).

2. The frame of claim 1, wherein the plurality of battery mounts each align and secure a battery pack transversely relative to the central plane and parallel to the ground.

3. The frame of claim 1, wherein the first portion includes opposing battery pack mounts that align and secure two layers of battery packs transversely relative to the central plane and parallel to the ground in opposing directions.

4. The frame of claim 1, wherein the lattice structure includes a primary lattice structure and a secondary lattice structure that is coupled to the primary lattice structure at the first portion of the lattice structure, wherein the primary lattice structure and the secondary lattice structure cooperate to align and secure two layers of battery packs.

5. The frame of claim 4, wherein the secondary lattice structure includes two segments, wherein one segment is coupled to the primary lattice structure on one side of the central plane and the other segment is coupled to the primary lattice structure on the opposite side of the central plane.

6. The frame of claim 5, wherein the two segments of the secondary lattice structure are substantially identical.

7. The frame of claim 1, wherein the frame is symmetric about the central plane.

8. The frame of claim 1, wherein the lattice structure defines a volume within the frame, and wherein the plurality of battery packs aligned and secured by the battery pack mounts occupy at least half of the volume defined by the lattice structure.

9. The frame of claim 8, wherein the battery packs aligned and secured by the battery pack mounts occupy at least 75% of the volume defined by the lattice structure.

10. The frame of claim 1, wherein the plurality of battery pack mounts defined by the lattice structure are each of a prismatic shape.

11. The frame of claim 10, wherein the plurality of battery pack mounts defined by the lattice structure are each of a triangular prismatic shape.

12. The frame of claim 1, wherein the lattice structure is composed of sheet metal.

13. The frame of claim 1, wherein the lattice structure includes fastening features to couple the plurality of battery packs to the plurality of battery pack mounts.

14. The frame of claim 13, wherein the fastening features include alignment features to align each of the plurality of battery packs to one of the plurality of battery pack mounts.

15. The frame of claim 1, further comprising a casing that envelops a substantial portion of the lattice structure.

16. The frame of claim 15, wherein the casing includes a first and second end cap, wherein the first end cap envelops the lattice structure on one side of the central plane and the second end cap envelops the lattice structure on the opposite side of the central plane.

17. The frame of claim 15, wherein the casing forms a hermetic seal around the plurality of battery packs.

18. The frame of claim 17, further comprising a pressure sensor contained within the casing that detects a pressure increase from a battery pack undergoing catastrophic failure.

19. The frame of claim 18, further comprising a processor that electrically decouples the battery pack undergoing catastrophic failure from the motorcycle.

20. A power source for a ride-on vehicle having at least one front wheel, and at least one rear wheel, comprising:

a plurality of battery packs; and

a frame defining a central plane and including a front end located adjacent to the front wheel(s), a rear end located adjacent to the rear wheel(s), and a lattice structure that extends substantially between the front end and the rear end and that defines a plurality of battery pack mounts, wherein the lattice structure includes a first portion that includes battery pack mounts that align and secure two layers of battery packs, wherein the lattice structure includes a second portion that includes battery pack mounts that align and secure a single layer of battery packs, and wherein the lattice structure defines a truss that mechanically couples the front wheel(s) to the rear wheel(s) and substantially maintains the relative position between the front wheel(s) and the rear wheel(s).
