Vehicle battery assembly
A vehicle includes a frame including a pair of spaced apart longitudinal members extending along a vehicle-longitudinal axis. Multiple cross-members extend transverse to the vehicle-longitudinal axis and are fastened at each end to a corresponding one of the pair of longitudinal members. A battery tray is positioned above the multiple cross-members and positioned between the longitudinal members.
1 . A vehicle, comprising:
a frame including a pair of spaced apart longitudinal members extending along a vehicle-longitudinal axis;
multiple cross-members extending transverse to the vehicle-longitudinal axis and fastened at each end to a corresponding one of the pair of longitudinal members; a battery tray positioned above the multiple cross-members and positioned between the longitudinal members; and
a fastening element attached to the battery tray and one of the multiple cross-members, the fastening element being frangible relative to the battery tray and the cross-member.
2 . The vehicle as set forth in claim 1 , wherein the battery tray has a bottom surface and channels in the bottom surface, the cross-members being in the channels, and the fastening element being in a corresponding one of the channels.
3 . The vehicle as set forth in claim 2 , wherein the fastening element is adhesive, and the adhesive is designed to separate from the battery tray and/or the cross-member when subjected to a shear-force in a cross-vehicle direction above a predetermined value.
4 . The vehicle as set forth in claim 3 , further comprising a cross-vehicle space between the longitudinal members and the battery tray.
5 . The vehicle as set forth in claim 1 , wherein the fastening element is adhesive.
6 . The vehicle as set forth in claim 5 , wherein the adhesive is designed to separate from the battery tray and/or the cross-member when subjected to a shear-force in a cross-vehicle direction above a predetermined value.
7 . The vehicle as set forth in claim 1 , wherein the battery tray has a bottom surface and channels in the bottom surface, the cross-members being in the channels.
8 . The vehicle as set forth in claim 7 , wherein the cross-members are below the longitudinal members.
9 . The vehicle as set forth in claim 8 , further comprising fasteners extending upwardly through the cross-members and into the longitudinal members.
10 . The vehicle as set forth in claim 9 , further comprising a cross-vehicle space between the longitudinal members and the battery tray.
11 . The vehicle as set forth in claim 1 , wherein the longitudinal members are spaced apart a frame distance and wherein the battery tray has a width less than the frame distance and further comprising a cross-vehicle space between the battery tray and each longitudinal member.
12 . The vehicle as set forth in claim 11 , wherein there are no structures positioned between the battery tray and the longitudinal members.
13 . The vehicle as set forth in claim 1 , wherein selected ones of the multiple cross-members are filled with expandable foam.
14 . The vehicle as set forth in claim 1 , wherein the frame comprises a unibody construction.
15 . A vehicle battery assembly comprising:
a battery tray having a longitudinal axis, a bottom surface, and multiple channels in the bottom surface;
multiple cross-members extending transverse to the longitudinal axis, each cross-member being positioned in a corresponding one of the multiple channels;
the battery tray is above the cross-members; and
adhesive attached to the battery tray and one of the multiple cross-members, the adhesive being frangible relative to the battery tray and the cross-member.
16 . The vehicle battery assembly as set forth in claim 15 , wherein the adhesive is designed to separate from the battery tray and/or the cross-member when subjected to a shear-force in a transverse direction above a predetermined value.
17 . The vehicle battery assembly as set forth in claim 15 , wherein the cross-members are tubular and include spacers positioned inside the cross-members at both ends of the cross-members.
18 . A vehicle, comprising:
a frame including a pair of spaced apart longitudinal members extending along a vehicle-longitudinal axis;
multiple cross-members extending transverse to the vehicle-longitudinal axis and fastened at each end to a corresponding one of the pair of longitudinal members;
a battery tray positioned above the multiple cross-members and positioned between the longitudinal members;
the battery tray having a bottom surface and channels in the bottom surface, the cross- members being in the channels;
the cross-members being below the longitudinal members; and
fasteners extending upwardly through the cross-members and into the longitudinal members.
19 . The vehicle as set forth in claim 18 , further comprising a fastening element attached to the battery tray and one of the multiple cross-members, the fastening element being frangible relative to the battery tray and the cross-member.
20 . The vehicle as set forth in claim 19 , wherein the battery tray has a bottom surface and channels in the bottom surface, the cross-members being in the channels, and the fastening element being in a corresponding one of the channels.
