  • Patent number: 12009538
    Abstract: A battery system includes: a battery stack including a plurality of rectangular battery cells that are stacked; end plate placed at both ends of the battery stack; and a binding bar that connects the end plates to fix the battery stack in a compressed state. End plate includes plates placed on both surfaces and plate-shaped block laminated between plates; plates include outer plate and inner plate; plate-shaped block includes dual-side blocks placed on both sides so as to be separated from each other and intermediate block placed in tapered groove between dual-side blocks; the tapered groove has a taper shape that gradually increases in width from an outside to an inside of the end plate. The intermediate block is placed in facing surfaces of the tapered groove in a slidable manner; the dual-side blocks are fixed to the plates; and intermediate block pressed by battery stack is press-fitted into tapered groove and end plate applies tensile stress to outer plate and inner plate via dual-side blocks.

  • Patent number: 11660951
    Abstract: A power supply device includes: a battery stack body that includes a plurality of secondary battery cells that are stacked; a pair of end plates disposed on both end surfaces of the battery stack body, respectively; and binding bars that are disposed on both the end surfaces of the battery stack body, respectively, and bind the pair of end plates. Each of the binding bars includes engaging steps that are opposite the pair of end plates, respectively. Each of the engaging steps extends in a direction intersecting with a stack direction of the battery stack body. Each of the pair of end plates includes engaging protrusions that are opposite the binding bars, respectively. The engaging protrusions engage with engaging steps. Consequently, rigidity that binds the battery stack body together is increased without changing a material and a thickness of the binding bars.

  • Patent number: 6435603
    Abstract: A structure for a front part of an automotive vehicle body having front side frames 2 extending longitudinal directions above a front axle 1, intermediate frames 5 connecting rear ends of the side frames 2 to front ends of floor frames 4 extending longitudinal directions underneath a floor of a passenger compartment and a dash panel 7 separating an engine compartment 6 from the passenger compartment, wherein the dash panel extends upwardly from longitudinally intermediate portions of the intermediate frames. With this construction, since the connecting points between the front side frames and the intermediate frames, i.e., the part that is to be bent by virtue of a crash load, are located forward of he dash panel, the effect on the deformation of the passenger compartment by the deformation of the frames can be alleviated.

  • Patent number: 5475376
    Abstract: In a safety-deposit box system including a safety-deposit box, a system controller, and a safety-deposit box controller, a multi-function key is used. The safety-deposit box has a lock and the multi-function key has a metal portion and an electronic memory. Information electronically stored on the electronic memory is read by a reception device and sent to a determination device in the system controller. The determination device compares the sent information with information prerecorded in an electronic memory in the system controller. When the two sets of information agree, the system controller outputs a signal to the safety-deposit box controller. After receiving the signal, the safety-deposit box controller checks mechanical appropriateness of the metal key portion and, if mechanically appropriate, unlocks the lock.
