Abstract

A battery case for a vehicle includes a tray member of resin, configured to hold batteries and having a plurality of projections formed on a bottom thereof, and a tray reinforcing member arranged so as to face the outer surface of the tray member and having at least one reinforcing member constituted by a metal plate, the reinforcing member being arranged on one side of the tray reinforcing member facing the tray member and raised from the one side of the tray reinforcing member. A recess is formed at least in the outer surface of one of the projections so as to correspond in position to the reinforcing member, and the reinforcing member is received in the recess.

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, the tray member having a plurality of projections formed on a bottom thereof; and

a tray reinforcing member arranged so as to face an outer surface of the tray member and having at least one reinforcing member constituted by a metal plate, the at least one reinforcing member being arranged on one side of the tray reinforcing member facing the tray member and raised from the one side of the tray reinforcing member, wherein;

a recess is formed at least in an outer surface of one of the projections so as to correspond in position to the reinforcing member, and

the reinforcing members are received in the respective recesses.

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

the tray member is configured to contain a plurality of batteries, and the projections are arranged such that the plurality of batteries are arrayed with the projections located therebetween.

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

the tray reinforcing member has a bottom wall covering a bottom plate of the tray member, and

the reinforcing member is fixed to the bottom wall of the tray reinforcing member.

4. The battery case according to claim 3, wherein the reinforcing member is a cut-and-raised portion obtained by cutting a portion of the bottom wall and raising the cut portion.

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

the tray reinforcing member has a frame member constituted by a metal plate covering an outer periphery of the tray member, and

the reinforcing member is fixed to an inner peripheral wall of the frame member.
