Transportation vehicle part and panel member therefor
View Patent ↗A transportation vehicle part that includes: a patch member constructed of a plate-like metal patch panel, and a vibration attenuating resin layer provided along a surface of the patch panel; and a metal base plate closely adhered with the vibration attenuating resin layer of the patch member and affixed with the patch member; according to this configuration, the transportation vehicle part which has a superior vibration characteristic without greatly increasing the thickness and the weight of the transportation vehicle part is provided.
1. A transportation vehicle part comprising:
a patch member constructed of
a plate-like metal patch panel, and
a vibration attenuating resin layer provided along a surface of the patch panel; and
a metal base plate closely adhered with the vibration attenuating resin layer of the patch member and affixed with the patch member,
wherein the patch panel and the base plate include a ridged portion, and the patch panel and the base plate are welded together at at least one part of a bent portion of the ridged portion, and
wherein a reinforcing member is provided on the surface of the base plate opposite to the surface on which the patch member is provided and the reinforcing member is provided at a position that faces the patch member.
2. A panel member comprising:
a patch member constructed of
a plate-like metal patch panel, and
a vibration attenuating resin layer provided along a surface of the patch panel; and
a metal base plate closely adhered with the vibration attenuating resin layer of the patch member and affixed with the patch member,
wherein the patch panel and the base plate include a ridged portion, and the patch panel and the base plate are welded together at least one part of a bent portion of the ridged portion.
3. The panel member according to claim 2 ,
wherein the transportation vehicle part is provided with a rigidity reinforced portion which has an uneven shape.
4. The panel member according to claim 2 ,
wherein the vibration attenuating resin layer is an electrically conductive.
5. The panel member part according to claim 2 ,
wherein the patch panel has a thickness of not less than 0.3 mm and not greater than a thickness of the base plate.
6. The panel member according to claim 2 ,
wherein the vibration attenuating resin layer has a thickness of not less than 10 μm and not greater than 1000 μm.
7. The panel member according to claim 2 ,
wherein the vibration attenuating resin layer is constructed of multiple layers which have different temperature characteristics with each other.
8. The panel member according to claim 7 ,
wherein a panel is inserted between the multiple layers.
9. The panel member according to claim 2 ,
wherein an uneven surface processing is performed on a surface of the patch panel or a surface of the base plate, which contacts the vibration attenuating resin layer.
