Abstract
A door structure of a vehicle includes: an outer panel (4); an inner member (5, 11A) arranged on an inner side of the outer panel in a vehicle width direction; a rigid member (9) arranged between the inner member (5, 11A) and the outer panel (4); and a vibration suppression member (22) arranged between the outer panel (4) and the rigid member (9). The outer panel (4) includes a hem section (10f, 10r, 10u) disposed on a periphery thereof and connected to the inner member (5, 11A) by swaging. The vibration suppression member (22) includes a damping material (22A to 22C) located adjacent to the hem section (10f, 10r, 10u) and being in contact with the outer panel (4) and the rigid member (9).
Claims18
A door structure of a vehicle, comprising:
- an outer panel;
- an inner member arranged on an inner side of the outer panel in a vehicle width direction;
- a rigid member arranged between the inner member and the outer panel;
- and
- a vibration suppression member arranged between the outer panel and the rigid member, wherein
- the outer panel includes a hem section disposed on a periphery thereof and connected to the inner member by swaging, and
- the vibration suppression member includes a plurality of damping materials arrayed in two upper and lower rows in a longitudinal direction of the rigid member, and
- at least a part of the damping materials is located adjacent to the hem section and in contact with the outer panel and the rigid member.
A door structure of a vehicle, comprising:
- an outer panel;
- an inner panel arranged on an inner side of the outer panel in a vehicle width direction;
- a door impact bar arranged between the inner panel and the outer panel, and extending from a front end to a rear end of the inner panel;
- and
- a vibration suppression member arranged between the outer panel and the door impact bar, wherein
- the outer panel includes a hem section disposed on a periphery thereof and connected to the inner panel by swaging,
- the vibration suppression member includes a plurality of damping materials arrayed in a front-rear direction and in contact with the outer panel and the door impact bar, and
- a pitch of the damping materials on a front end and a rear end of the impact bar adjacent to the hem section is smaller than a pitch of the damping materials in an intermediate portion of the impact bar in the front-rear direction.
