Abstract: A power storage device is provided with an upper cover, a cell module and a lower cover. A tab joint portion is locally formed at each of two sides of the cell module to be welded and assembled with a tab. When welded with the tab joint portion, the tab merely needs to be placed horizontally or be slightly at an inclination angle, and one-time bending is performed on an electrical connection part on the tab, so as to be electrically connected to an electrode of the upper cover. Therefore, the situation that a plasticized metal protective film wrapped on the outer edge of the tab or the cell module is easy to crack caused of many times of bending in the prior art can be improved.

Abstract: A latch assembly for a door includes a housing composed of a base and a cover. A drive knob, two links, two hooks, two adjusting members, and two torsion springs are connected between the base and the cover. The drive knob includes a drive surface that is engaged with a straight inside portion of a through hole of the links. One of the two links is pivotably connected to an adjusting portion of the other link and retaining slot of one of the two hooks. The other link has a positioning portion that is pivotably connected to the retaining slot of the other hook. When the drive knob is rotated in a particular direction (typically counterclockwise), the two links are pivoted in opposite directions and the two hooks are pivoted in two opposite directions and extend through apertures in the first outer surface of the base to hook a keeper structure and secure the door.
