Battery pack mounting architecture with shear plate for electric drive motor vehicles
First Claim
1. A shear plate for an electric vehicle with a chassis frame and a traction battery pack, the chassis frame including a front cradle with a cradle rail connected to a cradle cross member, and the traction battery pack including an electric battery module mounted on a support tray, the shear plate comprising:
- an elongated plate body with opposing fore and aft braces connected by opposing starboard and port braces, the fore brace being configured to mechanically couple to the cradle cross member of the front cradle, and the aft brace being configured to mechanically couple to the support tray of the traction battery pack, the elongated plate body further including a plurality of ribs disposed between the starboard and port braces and connecting the fore and aft braces,wherein the elongated plate body is configured to transmit load forces received from the front cradle via the fore brace, through the starboard and port braces, to the support tray via the aft brace.

Abstract
Disclosed are shear plates for structurally connecting vehicle chassis front cradles to battery pack support trays, methods for making and methods for using such shear plates, and electric vehicles with a chassis frame having a front cradle coupled to a battery pack support tray by a shear plate. A shear plate is disclosed for connecting a front cradle to a traction battery pack. The shear plate includes an elongated plate body with opposing fore and aft braces connected by opposing starboard and port braces. The fore brace directly mechanically couples to a cross member of the front cradle, whereas the aft brace directly mechanically couples to a support tray of the traction battery pack. The shear plate'"'"'s elongated body is designed to transmit in-plane and torsional forces received from the front cradle via the fore brace, through the starboard and port braces, to the support tray via the aft brace.

13. An electric vehicle, comprising:
-
a chassis frame with a front cradle having a pair of laterally spaced cradle rails connected by a transversely oriented cradle cross member; a traction battery pack anchored to the chassis frame and including a plurality of electric battery modules mounted on a support tray; an electric motor mounted above the front cradle and electrically connected to the traction battery pack; and a shear plate including an elongated plate body with opposing transversely oriented fore and aft braces connected by opposing laterally spaced starboard and port braces, the starboard and port braces being mechanically coupled to the chassis frame, the fore brace being directly mechanically coupled to the cradle cross member, and the aft brace being directly mechanically coupled to the support tray, the elongated plate body further including a plurality of ribs disposed between the starboard and port braces and connecting the fore and aft braces, wherein the elongated plate body is configured to transmit in-plane and torsional load forces received from the front cradle via the fore brace, through the ribs and the starboard and port braces, to the support tray via the aft brace.
