  • Publication number: 20210288363
    Abstract: A power supply device includes battery cells each having a rectangular external shape, a separator disposed between the battery cells, a pair of end plates that are disposed on respective ends of a battery assembly in which the separator and the battery cells are stacked, and a bind bar that binds the pair of end plates. The separator has insulating rib parts that protrude from both surfaces of the separator, and the insulating rib parts of the separator stacked on each surface of the battery cell are stacked on each other on a bottom surface of the battery cell. The insulating rib parts are stacked on each other on the bottom surface of the battery cell by inserting an insertion rib provided in one of the stacked insulating rib parts into an insertion groove provided in the other of the stacked insulating rib parts.

  • Patent number: 10658635
    Abstract: A battery pack including a lightweight and high-rigidity end plate is provided. The battery pack includes: cell stacked body including a plurality of stacked rectangular cells; first end plate disposed at one end of cell stacked body in the stacking direction of rectangular cells; second end plate disposed at the other end of cell stacked body; and connection member connected to first end plate and second end plate. At least one of first end plate and second end plate includes first member made of a first metal material and second member made of a second metal material different from the first metal material. First member and second member are stacked in the stacking direction of rectangular cells. The rigidity of the second metal material is higher than that of the first metal material. The specific gravity of the first metal material is lower than that of the second metal material.

  • Publication number: 20120142401
    Abstract: Disclosed is a portable terminal device, which has a reduced thickness, while ensuring a strength with which a display unit can be excellently held. In the device (100), the flat-board-like display unit (200) provided with a display drive section (213) that drives a liquid crystal display section (211) is attached to a first case (110) with a metal rear plate (160) therebetween. The rear plate (160) is provided with a reinforcing section (180), which is formed by folding back one plate end portion, which has a predetermined width, a plurality of times into a roll-shape on the rear surface side of the rear plate (160). The reinforcing section (180) is disposed at a position that includes the horizontal projection area of the display drive section (213), and prevents stress from concentrating on the display drive section (213) by reinforcing the display drive section (213).

  • Publication number: 20040095500
    Abstract: A mobile terminal device having a camera function and comprising a casing of reduced size, in which the arrangement of the functional components other than a camera unit is not restricted by the camera unit. The mobile terminal device (1) comprises a casing (2) having a liquid crystal display unit (15) on its surface (6) and camera unit (16) housed in a camera housing (17) provided on the right side face (7) of the terminal casing (2) in such a way that it can emerge/hide parallel with the casing surface (6) from/into the camera housing (17). The imaging lens section of the camera unit (16) is arranged on the side face of a rotary member (21) protruding from the camera housing (17). The rotary member (21) can rotate around the axis of protrusion with respect to a slide member (20) so as to adjust the imaging direction of the imaging lens unit of a camera body (53).
