  • Patent number: 9950748
    Abstract: In a battery frame, an upper panel is made of carbon fiber reinforced plastic, and first reinforcements are made of sheet metal. Head portions of rivets are disposed at the upper panel side, and a diameter dimension of the head portions is set larger than that of caulking portions of the rivets. This enables a contact surface area between the rivets and the upper panel to be larger than in cases in which the caulking portions are disposed at the upper panel side. This enables peripheral edge portions of first joint holes in the upper panel to be supported by the head portions of the rivets over a large surface area. The peripheral edge portions of the first joint holes in the upper panel are thereby suppressed from breaking and the like.

  • Patent number: 9533631
    Abstract: A corrugated plate portion of a core panel is sandwiched between an upper panel and a lower panel, and is formed in a shape in which upwardly-facing concave portions, that open toward a side of the upper panel and extend in a vehicle transverse direction, and downwardly-facing concave portions, that open toward a side of the lower panel and extend in the vehicle transverse direction, are lined-up alternately. A sum of contact surface areas of the upper panel and bottom wall portion sides of the downwardly-facing concave portions at the corrugated plate portion is smaller than a sum of contact surface areas of the lower panel and bottom wall portion sides of the upwardly-facing concave portions at the corrugated plate portion.
