Battery storage tray
This battery storage tray is provided with: a bottom plate which supports a plurality of batteries; a side wall which extends from the outer peripheral part of an upper surface of the bottom plate in the thickness direction of the bottom plate so as to surround a stage surface for the plurality of batteries in the upper surface, thereby defining a battery storage space, in which the plurality of batteries are contained, together with the bottom plate; and a plate-like permanent magnet which is affixed to at least a part of a bottom surface of the bottom plate.
1 . A battery housing tray, comprising:
a bottom plate that supports a plurality of batteries, wherein
a plurality of battery housing trays can be stacked in a plurality of stages, and
the plurality of battery housing trays includes the battery housing tray;
a side wall that defines a battery housing space for housing the plurality of batteries together with the bottom plate, the side wall extending in a thickness direction of the bottom plate from an outer edge of an upper surface of the bottom plate so as to surround a mounting surface of the plurality of batteries; and
a plate-shaped permanent magnet fixed to at least part of a bottom surface of the bottom plate, wherein
the plate-shaped permanent magnet has a magnetic force that does not attracts the plurality of batteries housed in the battery housing tray of a stage below of the plurality of stages, and
the magnetic force attracts one or more batteries of the plurality of batteries that jumped upward out of the battery housing tray of the stage below due to ignition.
2 . The battery housing tray according to claim 1 , comprising insulating resin coating at least part of the bottom surface of the permanent magnet.
3 . The battery housing tray according to claim 1 , wherein the battery housing space comprises a plurality of housing parts configured to house the batteries, respectively, and spaced from each other.
4 . The battery housing tray according to claim 3 , wherein the permanent magnet has a housing overlap part that overlaps at least part of the housing part as viewed in the thickness direction with respect to each of the plurality of housing parts.
5 . The battery housing tray according to claim 4 , wherein
the permanent magnet is fixed to a region on the bottom surface including all portions overlapped with the plurality of housing parts in the thickness direction, and
the battery housing tray comprises insulating resin that coats all of the bottom surface of the permanent magnet.
