Abstract

A door structure of a vehicle, capable of reliably transmitting a load, is provided. A rear side door ( 1 ) includes an inner panel ( 2 ) and an elongated door beam ( 4 ) that is attached to an outer side of the inner panel ( 2 ) in a vehicle width direction of a vehicle body and arranged along a front-rear direction of the vehicle body. The door beam ( 4 ) includes a first plate portion ( 11 ) of a first bracket ( 10 ), which has a first surface intersecting an axis along the vehicle width direction, and a vehicle width direction plate portion ( 21 ) of a second bracket ( 20 ), which has a second surface intersecting an axis along the front-rear direction of the vehicle body. The door beam ( 4 ) is joined to the inner panel ( 2 ) via both the first plate portion ( 11 ) and a second plate portion ( 12 ).

First claim

What is claimed is:

1. A door structure of a vehicle, comprising a door for opening and closing an opening formed in a vehicle body, wherein:
the door comprises an inner panel and an elongated door beam that is attached to an outer side of the inner panel in a vehicle width direction of the vehicle body and arranged along a front-rear direction of the vehicle body,
the door beam comprises a first surface member and a second surface member, wherein the first surface member has a first surface that intersects an axis along the vehicle width direction and the second surface member has a second surface that intersects an axis along the front-rear direction of the vehicle body, and
the door beam is joined to the inner panel via both the first surface and the second surface,
wherein a patch member respectively joined to the first surface and the second surface is disposed on an inner side in the vehicle width direction with respect to the inner panel,
wherein a first bracket having the first surface and a second bracket having the second surface are respectively connected to the door beam,
wherein the first bracket, the second bracket, and the door beam are joined on a surface that intersects the axis along the vehicle width direction,
wherein a third bracket is disposed between the door beam and the inner panel, and
the door structure of the vehicle comprises:
a first joining member joining the door beam, the third bracket, and the inner panel; and
a second joining member joining the third bracket and the inner panel at a position extending from the first joining member along a longitudinal direction of the door beam.

2. The door structure of the vehicle according to claim 1 , wherein the inner panel has an inner panel first surface arranged substantially in parallel to the first surface, an inner panel second surface arranged substantially in parallel to the second surface, and an inner panel connecting portion connecting the inner panel first surface and the inner panel second surface,
the patch member has a patch first surface arranged substantially in parallel to the inner panel first surface, a patch second surface arranged substantially in parallel to the inner panel second surface, and a patch connecting portion connecting the patch first surface and the patch second surface,
the first surface, the inner panel first surface, and the patch first surface are joined,
the second surface, the inner panel second surface, and the patch second surface are joined, and
the patch connecting portion is disposed apart from the inner panel connecting portion.

3. The door structure of the vehicle according to claim 1 , wherein the door comprises an outer panel disposed on the outer side of the inner panel and a fourth bracket in contact with the outer panel between the inner panel and the outer panel, and
