  • Patent number: 10513296
    Abstract: Structure including joint structure of dissimilar materials comprises a roof panel and a skeletal body. The roof panel has a bent portion at its end and is a panel member made of an aluminum alloy. The skeletal body has a support portion for supporting the first member and is made of steel. The roof panel and the skeletal body are joined by continuous welding of a vicinity of an apex of the bent portion of the roof panel and the support portion of the skeletal body, a reinforcing plate is joined to the roof panel at least partially along the joining portion with the skeletal body.

  • Publication number: 20190374994
    Abstract: In a joining method for members, a tube body having a center axis L, a wall surface body having a hole portion through which the tube body can be inserted, and an elastic body that can be inserted in the tube body are prepared. The tube body has an inner rib extending in a direction of the center axis so as to partition an inside thereof, and the inner rib has notches cut from a lower end of the inner rib in the direction of the center axis. Next, the tube body is inserted through the hole portion in the wall surface body, and the elastic body is inserted into internal spaces partitioned by the inner rib of the tube body. Furthermore, the elastic body is compressed in the direction of the center axis of the tube body and expanded outward in a radial direction with respect to the center axis, whereby an end of the tube body is expanded and deformed to be joined to the wall surface body by press-fitting.

  • Publication number: 20180306221
    Abstract: A side member (example of second member) having a hollow shape is inserted into holes formed in a cross member (example of first member) (member insertion step). The cross member and the side member are joined by caulking by expanding an insertion portion of the side member from the inside of the insertion portion (caulked junction step). The insertion portion of the side member is a portion inserted into the cross member.

  • Publication number: 20180272411
    Abstract: A method of bonding a first frame member and a second frame member includes: a protrusion formation step of forming a protrusion in a predetermined region of a plate by press fabrication; a stacking step of producing such a stack body of flanges and the plate that a leading end of the protrusion of the plate contacts with the flange and the flange is disposed between the flange and the plate; and a welding step of welding the protrusion to the flange by applying welding current between a pair of electrodes while the stack body is sandwiched between the pair of electrodes so that the protrusion is pressed against the flange.
