Description

BACKGROUND

The present disclosure relates generally to vehicle components and, more particularly, to methods and systems for use in supporting a battery in a vehicle environment.

At least some known battery supports are fabricated primarily from sheet metal. As a result, known battery support configurations are limited to sheet metal-forming restrictions. As such, known battery supports fabricated from sheet metal generally have simple configurations and are locally reinforced using stamped-metal parts that are welded and/or coupled to the supports. Although the stamped-metal parts may increase an overall strength and/or durability of the battery support, such parts also increase the overall weight of the battery support, which may negatively impact the operational performance of a vehicle.

BRIEF DESCRIPTION

In one aspect, a battery support is provided. The battery support includes a base having an upper surface and a lower surface, a spine extending downwardly from and axially along the base such that at least a portion of the base is cantilevered from the spine, and at least one rib extending downwardly from the base and laterally from the spine. The upper surface is sized to support a battery thereon.

In another aspect, a method is provided for supporting a battery. The method includes coupling a spine to a rail generally along an axial direction. The spine extends generally axially downwardly from the a base such that at least a portion of the base is cantilevered from the spine. At least one rib extends generally downwardly from the base and generally laterally from the spine. The cantilevered portion of the base and the at least one rib extend generally laterally from the spine generally in a first direction. The cantilevered portion of the base extends generally laterally from the spine at a first elevation. A flange is coupled to the rail generally along the axial direction such that the flange extends generally laterally from the spine in a second direction opposite the first direction. The flange extends generally laterally from the spine at a second elevation different from the first elevation such that the cantilevered portion of the base and the flange are vertically offset.

As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural elements or steps unless such exclusion is explicitly recited. Furthermore, references to “one embodiment” of the present invention or the “exemplary embodiment” are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

FIG. 1 is a perspective view of an exemplary battery support system 100. In the exemplary embodiment, battery support system 100 includes a rail 110 that extends generally along an X-axis 120 (i.e., axially). In the exemplary embodiment, a battery support 130 is coupled to rail 110. More specifically, in the exemplary embodiment, battery support 130 extends outwardly from rail 110 generally along a Y-axis 140 that is substantially perpendicular to the X-axis 120 (i.e., laterally) such that battery support 130 is maintained in a cantilevered configuration. In the exemplary embodiment, a battery 150 is positioned on top of battery support 130 such that battery 150 induces a downward load generally along a Z-axis 160 that is substantially perpendicular to the X-axis 120 and/or the Y-axis 140 (i.e., vertically).

FIG. 2 is an end view (i.e., shows the Y-Z plane) of battery support 130. FIG. 3 is a side view (i.e., shows the X-Z plane) of battery support 130. FIG. 4 is a top view (i.e., shows the X-Y plane) of battery support 130. In the exemplary embodiment, battery support 130 includes a base 170 having an upper surface 180 (shown in FIGS. 2 and 3) and a lower surface 190 (shown in FIGS. 2 and 3). In the exemplary embodiment, upper surface 180 and/or lower surface 190 are oriented generally within the X-Y plane. Moreover, in the exemplary embodiment, upper surface 180 is sized and/or configured to receive and/or support at least a portion of battery 150. Alternatively, upper surface 180 and/or lower surface 190 may have any size, shape, and/or orientation that enables battery support 130 to function as described herein.

In the exemplary embodiment, base 170 includes a first outer edge portion 200 (shown in FIG. 4) and a second outer edge portion 210 (shown in FIG. 4) that each extend generally laterally. In the exemplary embodiment, first edge portion 200 and second edge portion 210 are spaced apart generally axially. Moreover, in the exemplary embodiment, base 170 includes a first wall 220 (shown in FIG. 4) and a second wall 230 (shown in FIG. 4) that extend within the Y-Z plane. More specifically, in the exemplary embodiment, first wall 220 extends generally upwardly from first outer edge portion 200, and second wall 230 extends generally upwardly from second outer edge portion 210. Accordingly, in the exemplary embodiment, first wall 220 and second wall 230 are spaced apart generally axially. Alternatively, first wall 220 and/or second wall 230 may be aligned in any orientation that enables battery support 130 to function as described herein.

In the exemplary embodiment, a spine 240 (shown in FIGS. 2 and 3) extends generally within the X-Z plane. More specifically, in the exemplary embodiment, spine 240 extends generally downwardly from lower surface 190 and is positioned such that at least a portion of base 170 is cantilevered from spine 240 and/or rail 110. In the exemplary embodiment, spine 240 is coupled to a side face 250 (shown in FIG. 1) of rail 110, generally along the X-axis 120. More specifically, in the exemplary embodiment, spine 240 includes a plurality of openings 260 (shown in FIG. 3) that extend generally laterally therethrough. In the exemplary embodiment, each opening 260 is sized, shaped, and/or oriented to receive a respective coupling mechanism 270 (shown in FIG. 1) therethrough for use in coupling battery support 130 to rail 110. Accordingly, in the exemplary embodiment, coupling mechanism 270 facilitates maintaining a relative lateral position of battery support 130. In the exemplary embodiment, coupling mechanism 270 is a bolt. Alternatively, any coupling mechanism 270 may be used that enables battery support 130 to function as described herein.

In the exemplary embodiment, spine 240 includes at least one mechanism that enables spine 240 to “fail” generally in the X-axis 120.

For example, in the exemplary embodiment, spine 240 includes at least one line of weakness 280 (shown in FIG. 3) that extends generally axially between openings 260 and base 170. Accordingly, in the exemplary embodiment, base 170 is positioned on a first side 290 (shown in FIG. 3) of line of weakness 280, and openings 260 are positioned on an opposite second side 300 (shown in FIG. 3) of line of weakness 280. In the exemplary embodiment, spine 240 is pre-configured to divide along line of weakness 280 such that first side 290 separates from second side 300 when battery support 130 sustains an axial load that is greater than a predetermined threshold. Moreover, in the exemplary embodiment, spine 240 includes at least one outer edge 310 (shown in FIG. 3) that at least partially defines a recess 320 (shown in FIG. 3) positioned on second side 300, generally between openings 260. Accordingly, in the exemplary embodiment, the size and/or relative positioning of recess 320 facilitates decreasing a size and/or length of line of weakness 280. Alternatively, line of weakness 280 and/or recess 320 may have any size, shape, and/or length that enables spine 240 to function as described herein.

In the exemplary embodiment, at least one rib 330 (shown in FIGS. 2 and 3) extends generally within the Y-Z plane. More specifically, in the exemplary embodiment, rib 330 extends generally downwardly from lower surface 190 and is positioned to provide vertical support to base 170. In the exemplary embodiment, rib 330 extends generally laterally from spine 240 generally in the same direction as the cantilevered portion of base 170. In the exemplary embodiment, rib 330 is substantially positioned between first wall 220 and second wall 230. More specifically, in the exemplary embodiment, rib 330 is substantially parallel to first wall 220 and/or second wall 230. Alternatively, rib 330 may be aligned in any orientation that enables battery support 130 to function as described herein.

In the exemplary embodiment, at least one flange 340 (shown in FIGS. 2 and 4) extends generally within the X-Y plane. More specifically, in the exemplary embodiment, flange 340 extends generally laterally from spine 240 in a direction opposite rib 330 and/or the cantilevered portion of base 170. In the exemplary embodiment, flange 340 is coupled to an upper face 350 (shown in FIG. 1) of rail 110 generally along the X-axis 120. More specifically, in the exemplary embodiment, flange 340 includes at least one opening 360 (shown in FIG. 4) extending generally vertically therethrough. In the exemplary embodiment, each opening 360 is sized, shaped, and/or oriented to receive a respective coupling mechanism 370 (shown in FIG. 1) therethrough for use in coupling battery support 130 to rail 110. Accordingly, in the exemplary embodiment, coupling mechanism 370 facilitates maintaining a relative vertical position of battery support 130. In the exemplary embodiment, coupling mechanism 370 is a bolt. Alternatively, any coupling mechanism 370 may be used that enables battery support 130 to function as described herein.

In the exemplary embodiment, flange 340 includes at least one mechanism that enables flange 340 to “fail” generally in the X-axis 120. More specifically, in the exemplary embodiment, flange 340 is configured and/or designed to address axial loading issues. For example, in the exemplary embodiment, flange 340 includes at least one line of weakness 380 (shown in FIG. 4) that extends between openings 360 and base 170. Accordingly, in the exemplary embodiment, base 170 is positioned on a first side 390 (shown in FIG. 4) of line of weakness 380, and openings 360 are positioned on an opposite second side 395 (shown in FIG. 4) of line of weakness 380. In the exemplary embodiment, flange 340 is pre-configured to divide along line of weakness 380 such that first side 390 separates from second side 395 when battery support 130 sustains an axial load that is greater than a predetermined threshold. Alternatively, line of weakness 380 may have any size, shape, and/or length that enables flange 340 to function as described herein.
