The information provided in this section is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
The present disclosure relates to a vehicle frame with an integrated battery enclosure.
Current industry battery frame designs rely on a battery pack that have a separate battery enclosure that is loaded to a traditional vehicle frame. The pack requires internal load clearance to build the module and internal components. The battery pack requires load clearance to the frame in general assembly. The combination of the clearances reduces a volume for cells, which reduces pack energy.
This present disclosure integrates the frame and battery enclosure as one to provide additional volume for battery energy. This present disclosure reduces the internal clearance required to build the pack and uses the space to eliminate general assembly load clearances. It reduces clearances allocated for draft angles of the cover and provides additional space for pack energy
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
A vehicle frame includes a first vehicle frame side rail and a second vehicle frame side rail spaced laterally from the first vehicle frame side rail. An upper battery enclosure having an upper wall and a pair of side walls. A cross beam extends through a respective pair of apertures in the pair of side walls of the battery enclosure and through an aperture in the first vehicle frame side rail and an aperture in the second vehicle frame side rail. A battery tray is secured below the pair of side walls of the upper battery enclosure.
A vehicle frame includes a first vehicle frame side rail and a second vehicle frame side rail spaced laterally from the first vehicle frame side rail. A pair of enclosure panels extend between the first vehicle frame side rail and the second vehicle frame side rail. A shear panel is welded and sealed to a respective top surface of each of the first vehicle frame side rail and the second vehicle frame side rail and to the pair of enclosure panels. A battery tray is secured to the first vehicle frame side rail and the second vehicle frame side rail.

An enclosure panel extends between the first vehicle frame side rail and the second vehicle frame side rail. A battery tray is secured to the first vehicle frame side rail and the second vehicle frame side rail. A seal is disposed between the battery tray and each of the first vehicle frame side rail, the second vehicle frame side rail and the at least one enclosure panel.
Further areas of applicability of the present disclosure will become apparent from the detailed description, the claims and the drawings. The detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.
The present disclosure will become more fully understood from the detailed description and the accompanying drawings, wherein:
In the drawings, reference numbers may be reused to identify similar and/or identical elements.
Example embodiments will now be described more fully with reference to the accompanying drawings.

The upper battery enclosure 18 further includes a rear wall 42 and an outwardly extending flange 44 extending from the pair of sidewalls 22, 24 and the rear wall 42. An additional enclosure panel 45 can be used to enclose a forward end of the upper battery enclosure 18. As best shown in

A plurality of battery cells 52 are supported on the battery tray 40 and disposed within the battery enclosure 12. By integrating the battery enclosure 12 into the vehicle frame 10 and further eliminating additional cross beams, a volume of the battery enclosure 12 can be maximized. The maximization of the volume of the battery enclosure 12 allows for a larger number of battery cells 52 to be packaged within the battery enclosure 12 and thus provides an increased energy density for the pack and provides additional vehicle range. The enclosure 12 is part of the frame structure 10 and provides sealing for the battery back. By integrating the enclosure 12 into the vehicle frame can also result in mass reduction without sacrificing frame strength.

The foregoing description is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. The broad teachings of the disclosure can be implemented in a variety of forms. Therefore, while this disclosure includes particular examples, the true scope of the disclosure should not be so limited since other modifications will become apparent upon a study of the drawings, the specification, and the following claims. It should be understood that one or more steps within a method may be executed in different order (or concurrently) without altering the principles of the present disclosure. Further, although each of the embodiments is described above as having certain features, any one or more of those features described with respect to any embodiment of the disclosure can be implemented in and/or combined with features of any of the other embodiments, even if that combination is not explicitly described. In other words, the described embodiments are not mutually exclusive, and permutations of one or more embodiments with one another remain within the scope of this disclosure.
Spatial and functional relationships between elements (for example, between modules, circuit elements, semiconductor layers, etc.) are described using various terms, including “connected,” “engaged,” “coupled,” “adjacent,” “next to,” “on top of,” “above,” “below,” and “disposed.” Unless explicitly described as being “direct,” when a relationship between first and second elements is described in the above disclosure, that relationship can be a direct relationship where no other intervening elements are present between the first and second elements, but can also be an indirect relationship where one or more intervening elements are present (either spatially or functionally) between the first and second elements. As used herein, the phrase at least one of A, B, and C should be construed to mean a logical (A OR B OR C), using a non-exclusive logical OR, and should not be construed to mean “at least one of A, at least one of B, and at least one of C.”
