Abstract: A battery casing includes a battery seat, a hinged cover and an ejector member. The hinged cover is mounted pivotally to the battery seat for pivoting about a horizontal pivot axis so as to be movable between open and closed positions. The ejector member has a first end portion extending into the battery chamber, and a second end portion opposite to the first end portion and extending out of the battery chamber. The second end portion of the ejector member engages the side wall of the hinged cover. When the hinged cover is moved to an open position, the second end portion of the ejector member moves with the side wall of the hinged cover so as to cause corresponding upward movement of the first end portion of the ejector member away from the base wall, thereby enabling the ejector member to eject the battery from the battery chamber.

Abstract: A battery casing includes a battery seat, a hinged cover and an ejector member. The battery seat has a base wall and a surrounding wall unit which cooperatively form a battery chamber with a top opening. The hinged cover has a top wall and a side wall extending downwardly from the top wall and having a lower hinge end portion which is disposed adjacent to the surrounding wall unit and externally of the battery chamber, and which is mounted pivotally to the battery seat for pivoting about a horizontal pivot axis so as to be movable between open and closed positions. The ejector member is disposed on the surrounding wall unit, and has a first end portion extending into the battery chamber, and a second end portion opposite to the first end portion and extending out of the battery chamber. The second end portion of the ejector member engages the side wall of the hinged cover.
