Cell holding device, assembled battery, and vehicle

摘要

In a cell holding device, engaging members (224) are disposed in an insertion cavity (222) into which an end portion of each cell (400) is inserted, such that the engaging members (224) are movable in a direction of insertion in which the cell (400) is inserted. The cell holding device also has guides (225) that push the engaging members (224) toward the inner radius of the insertion cavity (222) as the engaging members (224) move in the direction of insertion. With this arrangement, when the end portion of the cell (400) is inserted into the insertion cavity (222), the engaging members (224) sandwiched between the guides (225) and a side circumferential surface (403) of the cell (400) hold the end portion of the cell (400).

主权项

1. A cell holding device for holding end portions of cells of a battery, comprising:
an insertion cavity into which the end portion of each of the cells is inserted; an engaging member disposed in the insertion cavity such that the engaging member is movable in a direction of insertion in which the end portion of the cell is inserted, wherein the engaging member includes an abutting portion that abuts on an end face of the cell; and a guide that pushes the engaging member toward an inner radius of the insertion cavity as the engaging member moves in the direction of insertion, wherein: the engaging member is fitted in a groove formed as a concave portion on an inner circumferential surface of the insertion cavity, and the guide includes a tapered face formed at the bottom of the groove, and when the end portion of the cell is inserted into the insertion cavity,
the engaging member that is sandwiched between the guide and a side circumferential surface of the cell holds the end portion of the cell, andthe abutting portion is pushed by the end face of the cell so that the engaging member moves to a bottom of the insertion cavity to be sandwiched between the tapered face and the side circumferential surface of the cell.
