Abstract

Vertical frame portions provided at both side portions of a door frame are a light-metal casting, plural connecting frames, which are a light-meal hollow extrusion molding, connect the vertical frame portions, the vertical frame portions are provided with protrusion portions which engage with inward connecting frames in a longitudinal direction, plural attachment portions which attach the outward connecting frames and the vertical frame portion are provided at different points in the longitudinal direction, and an outward connecting frame is provided with an upper rib which engages with an engagement recess portion provided at an upper portion of a door outer panel formed in a non-planar shape.

First claim

What is claimed is:

1. A door structure of an automotive vehicle, comprising:
a door frame comprising a front-side vertical frame portion and a rear-side vertical frame portion which are respectively provided at front-and-rear side portions, in a vehicle longitudinal direction, of the door frame and plural connecting members which connect the front-side and rear-side vertical frame portions at a beltline position of a door, the front-side and rear-side vertical frame portions being a light-metal casting, the plural connecting members being a light metal hollow extrusion molding, wherein said light metal is aluminum, alloy of aluminum, magnesium, or alloy of magnesium; and
a door outer panel formed in a non-planar shape,
wherein said plural connecting members of the door frame comprise an inward-beltline connecting member which is positioned on an inward side, in a vehicle width direction, of the door frame and an outward-beltline connecting member which is positioned on an outward side, in the vehicle width direction, of the inward-beltline connecting member of the door frame,
said front-side and rear-side vertical frame portions of the door frame are provided with protrusion portions which respectively engage with said inward-beltline connecting member in a longitudinal direction of the inward-beltline connecting member,
plural attachment portions which attach said outward-beltline connecting member and said front-side and rear-side vertical frame portions are provided at different points in a longitudinal direction of the outward-beltline connecting member,
said outward-beltline connecting member is provided with a rib or flange which engages with an engagement portion provided at an upper portion of said door outer panel, and
said door outer panel is made of resin, and said engagement portion provided at the door outer panel comprises an engagement protrusion piece which protrudes downward and extends in the vehicle width direction at a lower face of the upper portion of the door outer panel and an engagement recess portion which is formed at the engagement protrusion piece so as to match said rib or flange provided at the outward-beltline connecting member for engaging therewith.

2. The door structure of the automotive vehicle of claim 1 , wherein said door frame further comprises a lower connecting frame which is provided at a lower level than said inward-beltline connecting member so as to connect the front-side and rear-side vertical frame portions.

3. The door structure of the automotive vehicle of claim 2 , wherein the upper portion of said door outer panel and one of a front edge side and a rear edge side of the door outer panel engage with said door frame, and a lower portion of the door outer panel and the other of the front edge side and the rear edge side of the door outer panel are fixedly joined to the door frame by using a fixing means.

4. The door structure of the automotive vehicle of claim 3 , wherein said inward-beltline connecting member and said protrusion portions of the front-side and rear-side vertical frame portions which engage with the inward-beltline connecting member are fixed by an adhesive agent and a pin.

5. The door structure of the automotive vehicle of claim 4 , wherein the door is a side door, and said front-side vertical frame portion of the door frame overlaps a hinge pillar when viewed from a vehicle side and said rear-side vertical frame portion of the door frame overlaps a pillar located in back of the door when viewed from the vehicle side.

6. The door structure of the automotive vehicle of claim 3 , wherein the door is a side door, and said front-side vertical frame portion of the door frame overlaps a hinge pillar when viewed from a vehicle side and said rear-side vertical frame portion of the door frame overlaps a pillar located in back of the door when viewed from the vehicle side.

7. The door structure of the automotive vehicle of claim 2 , wherein said inward-beltline connecting member and said protrusion portions of the front-side and rear-side vertical frame portions which engage with the inward-beltline connecting member are fixed by an adhesive agent and a pin.

8. The door structure of the automotive vehicle of claim 7 , wherein the door is a side door, and said front-side vertical frame portion of the door frame overlaps a hinge pillar when viewed from a vehicle side and said rear-side vertical frame portion of the door frame overlaps a pillar located in back of the door when viewed from the vehicle side.

9. The door structure of the automotive vehicle of claim 2 , wherein the door is a side door, and said front-side vertical frame portion of the door frame overlaps a hinge pillar when viewed from a vehicle side and said rear-side vertical frame portion of the door frame overlaps a pillar located in back of the door when viewed from the vehicle side.

10. The door structure of the automotive vehicle of claim 1 , wherein the upper portion of said door outer panel and one of a front edge side and a rear edge side of the door outer panel engage with said door frame, and a lower portion of the door outer panel and the other of the front edge side and the rear edge side of the door outer panel are fixedly joined to the door frame by using a fixing means.

11. The door structure of the automotive vehicle of claim 10 , wherein said inward-beltline connecting member and said protrusion portions of the front-side and rear-side vertical frame portions which engage with the inward-beltline connecting member are fixed by an adhesive agent and a pin.

12. The door structure of the automotive vehicle of claim 11 , wherein the door is a side door, and said front-side vertical frame portion of the door frame overlaps a hinge pillar when viewed from a vehicle side and said rear-side vertical frame portion of the door frame overlaps a pillar located in back of the door when viewed from the vehicle side.

13. The door structure of the automotive vehicle of claim 10 , wherein the door is a side door, and said front-side vertical frame portion of the door frame overlaps a hinge pillar when viewed from a vehicle side and said rear-side vertical frame portion of the door frame overlaps a pillar located in back of the door when viewed from the vehicle side.

14. The door structure of the automotive vehicle of claim 1 , wherein said inward-beltline connecting member and said protrusion portions of the front-side and rear-side vertical frame portions which engage with the inward-beltline connecting member are fixed by an adhesive agent and a pin.

15. The door structure of the automotive vehicle of claim 14 , wherein the door is a side door, and said front-side vertical frame portion of the door frame overlaps a hinge pillar when viewed from a vehicle side and said rear-side vertical frame portion of the door frame overlaps a pillar located in back of the door when viewed from the vehicle side.
