Abstract

An embodiment swing door mounting structure for a vehicle includes a roof side reinforcement member coupled to an inner side of a cross section of a roof side of a side structure in a vehicle body front and rear direction and a door mounting member coupled to the roof side reinforcement member to define an open cross section for mounting a swing door on the roof side.

First claim

What is claimed is:

1 . A swing door mounting structure for a vehicle, the structure comprising:
a roof side reinforcement member coupled to an inner side of a cross section of a roof side of a side structure in a vehicle body front and rear direction, wherein the roof side reinforcement member has a downwardly concave cross section shape and is coupled to a lower portion of a roof side upper member to define a center closed section in the vehicle body front and rear direction; and a door mounting member coupled to the roof side reinforcement member to define an open cross section for mounting a swing door on the roof side.

2 . The structure of claim 1 , wherein the door mounting member is coupled to a lower portion of the roof side reinforcement member to define the open cross section of a ‘⊏’ shape in a vehicle width direction and is coupled to a roof side inner panel.

3 . The structure of claim 1 , further comprising a center bulk head coupled to a center portion of the roof side reinforcement member.

4 . The structure of claim 3 , further comprising a center roof rail extending to the inner side of the cross section of the roof side and coupled to the center bulk head in a vehicle width direction.

5 . The structure of claim 1 , further comprising a front side reinforcement member disposed in an inner side of a cross section of a front side of the side structure and coupled to the roof side reinforcement member through a first gusset in the vehicle body front and rear direction.

6 . The structure of claim 5 , wherein a front closed section connected to a center closed section between the roof side upper member and the roof side reinforcement member is defined between a front side upper member and the front side reinforcement member.

7 . The structure of claim 5 , further comprising:
a first front roof rail extending to the inner side of the cross section of the front side and coupled to a second gusset on the front side reinforcement member in a vehicle width direction at a position corresponding to a front pillar of the front side; and a second front roof rail extending to the inner side of the cross section of the front side and coupled to the first gusset in the vehicle width direction at a position corresponding to a first door support pillar of the front side.

8 . The structure of claim 1 , further comprising a rear side reinforcement member disposed in an inner side of a cross section of a rear side of the side structure and coupled to the roof side reinforcement member through a third gusset in the vehicle body front and rear direction.

9 . The structure of claim 8 , wherein a rear closed section connected to a center closed section between the roof side upper member and the roof side reinforcement member is defined between a rear side upper member and the rear side reinforcement member.

10 . The structure of claim 8 , further comprising:
a first rear roof rail extending to the inner side of the cross section of the rear side and coupled to a fourth gusset in the rear side reinforcement member in a vehicle width direction at a position corresponding to a rear pillar of the rear side; and a second rear roof rail extending to the inner side of the cross section of the rear side and coupled to the third gusset in the vehicle width direction at a position corresponding to a second door support pillar of the rear side.

11 . A swing door mounting structure for a vehicle, the structure comprising:
a roof side reinforcement member coupled to an inner side of a cross section of a roof side of a side structure in a vehicle body front and rear direction, wherein the roof side reinforcement member has a downwardly concave cross-section shape and is coupled to a lower portion of a roof side upper member to define a center closed section in the vehicle body front and rear direction; a door mounting member coupled to the roof side reinforcement member to define an open cross section for mounting a swing door on the roof side; and a pipe nut coupled to the roof side upper member and the roof side reinforcement member in an up and down direction in a center closed section between the roof side upper member and the roof side reinforcement member.

12 . The structure of claim 11 , further comprising a fastening bolt fastened to the pipe nut and to which a link arm coupled to the swing door is rotatably coupled.

13 . The structure of claim 12 , wherein the fastening bolt is coupled to a roof side inner panel and the door mounting member through a head portion.

14 . The structure of claim 12 , wherein the link arm comprises a boss portion rotatably coupled to the fastening bolt between the roof side reinforcement member and the door mounting member.

15 . The structure of claim 12 , wherein a reinforcement plate is coupled to the door mounting member to support a head portion of the fastening bolt.

16 . A vehicle comprising:
a vehicle body comprising a side structure extending in a longitudinal direction of the vehicle body, wherein each of the side structures comprises a front side, a roof side, and a rear side; a roof side upper member; a roof side reinforcement member coupled to an inner side of a cross section of the roof side of the side structure in the longitudinal direction of the vehicle body, wherein the roof side reinforcement member has a downwardly concave cross-section shape and is coupled to a lower portion of the roof side upper member to define a center closed section in the longitudinal direction of the vehicle body; and a door mounting member coupled to the roof side reinforcement member to define an open cross section; and a swing door mounted to the door mounting member on the roof side.

17 . The vehicle of claim 16 , further comprising:
a center bulk head coupled to a center portion of the roof side reinforcement member; and a center roof rail extending to the inner side of the cross section of the roof side and coupled to the center bulk head in a vehicle width direction.

18 . The vehicle of claim 16 , further comprising:
a front side reinforcement member disposed in an inner side of a cross section of the front side of the side structure and coupled to the roof side reinforcement member through a first gusset in the longitudinal direction of the vehicle body; a first front roof rail extending to the inner side of the cross section of the front side and coupled to a second gusset on the front side reinforcement member in a vehicle width direction at a position corresponding to a front pillar of the front side; and a second front roof rail extending to the inner side of the cross section of the front side and coupled to the first gusset in the vehicle width direction at a position corresponding to a first door support pillar of the front side.

19 . The structure of claim 11 , wherein the door mounting member is coupled to a lower portion of the roof side reinforcement member to define the open cross section of a ‘⊏’ shape in a vehicle width direction and is coupled to a roof side inner panel.

20 . The structure of claim 11 , further comprising a center bulk head coupled to a center portion of the roof side reinforcement member.
