Abstract

A battery case for a vehicle includes a tray member (22) made of resin and configured to hold a battery (38), one or more beam members (30) arranged so as to extend in at least one of width and longitudinal directions of the tray member, the one or more beam members supporting the tray member and having a recess (50) formed therein, and a bottom wall (58) interposed between the tray member and the one or more beam members and closing an aperture plane of the recess of the one or more beam members to form a closed cross-section, the bottom wall being constituted by a continuous metal plate underlying a bottom plate of the tray member.

Claims

1. A battery case for containing a battery for driving a vehicle, comprising:

a tray member made of a resin and configured to hold the battery;

one or more beam members arranged so as to extend in at least one of width and longitudinal directions of the tray member, the one or more beam members supporting the tray member and having a recess formed therein; and

a bottom wall interposed between the tray member and the one or more beam members and closing an aperture plane of the recess of the one or more beam members to form a closed cross-section, the bottom wall being constituted by a continuous metal plate underlying a bottom plate of the tray member.

2. The battery case according to claim 1, wherein:

the one or more beam members include a first beam member extending in the width direction of the tray member, and a second beam member extending in the longitudinal direction of the tray member, and

the first and second beam members have respective aperture planes substantially flush with each other and closed by the bottom wall.

3. The battery case according to claim 1, further comprising a frame member constituted by a metal plate covering an outer periphery of the tray member,

wherein the bottom wall is fixed to the frame member.
