Battery accommodation tray
The purpose of the present disclosure is to provide a battery accommodation tray in which the amount of material used is readily reduced and of which the strength is readily improved. The battery accommodation tray comprises a plurality of accommodation parts that respectively accommodate batteries and that are positioned at intervals from each other. The accommodation parts have insertion openings demarcated by insertion-side circular parts that have a circular shape when viewed from the insertion side of the batteries in the height direction (Z direction). The battery accommodation tray has insertion-side connection parts by which the outer peripheral surfaces of the insertion-side circular parts are connected to the outer peripheral surfaces of adjacent insertion-side circular parts. The plurality of insertion-side circular parts are connected by the plurality of insertion-side connection parts to form an integrated whole.
1 . A battery housing tray comprising a battery housing structure, wherein the battery housing structure comprises:
a plurality of housing parts that each house a battery and are disposed spaced apart from each other, each of the housing parts including
an insertion opening demarcated by an insertion-side annular part having an annular shape when seen from an insertion side of the battery in a height direction, and
a receiving-side annular part that has an annular shape and supports the battery housed in the housing part, on an opposite side to the insertion opening side in the height direction;
an insertion-side joining part for joining an outer peripheral surface of the insertion-side annular part to an outer peripheral surface of another insertion-side annular part next to the insertion-side annular part; and
a receiving-side joining part for joining an outer peripheral surface of the receiving-side annular part to an outer peripheral surface of another receiving-side annular part next to the receiving-side annular part,
wherein
a plurality of the insertion-side annular parts are joined and integrated by a plurality of the insertion-side joining parts,
a plurality of the receiving-side annular parts are joined and integrated by a plurality of the receiving-side joining parts, and
an extending direction of the receiving-side joining part is inclined with respect to an extending direction of the insertion-side joining part.
2 . The battery housing tray according to claim 1 , wherein
the plurality of insertion-side joining parts are disposed in a grid pattern, and
each of the insertion-side joining parts is positioned on a line segment connecting a center of the insertion-side annular part and a center of another insertion-side annular part next to the insertion-side annular part when seen from the insertion side of the battery in the height direction.
3 . The battery housing tray according to claim 1 , wherein, in each of the housing parts, a side wall covering a side surface of the battery housed in the housing part has a notch for communicating an inner space of the housing part with an outer space of the housing part.
