Abstract

A door of a vehicle may include a first door module forming a door skeleton; and a second door module coupled with the first door module and forming a door window; wherein the second door module includes a relatively lightweight material as compared to the first door module; a reinforcement member is inserted along an edge portion forming the door window of the second door module; and a stepped portion is formed at the reinforcement member, reducing weight and cost of the door of the vehicle.

First claim

What is claimed is:

1. A door of a vehicle, the door comprising:
a first door module forming a door skeleton;
a second door module coupled with the first door module and forming a door window;
a reinforcement member inserted into and integrally molded with the second door module along an edge portion forming the door window of the second door module; and
a stepped portion formed on the reinforcing member,
wherein the second door module includes:
a module body formed in a panel shape; and
a door window portion forming the door window and being integrally formed with the module body,

wherein the door window portion includes:
a roof portion corresponding to a roof profile of a vehicle body;
a center pillar portion corresponding to a center pillar of the vehicle body when the door is closed to the vehicle body; and
a first belt line portion for forming a belt line of the door,
wherein the reinforcement member is formed in a profile corresponding to the roof portion and the center pillar portion of the door window and the first belt line portion of the module body and inserted thereto,
wherein each of the roof portion, the center pillar portion and a body of the first belt line portion of the second door module is provided with a boss having a closed cross section which includes a hollow inner space into which the reinforcement member is inserted, and wherein the stepped portion is positioned on the first belt line portion of the module body.

2. The door of claim 1 , wherein the first door module includes a metal material and the second door module includes a plastic material, and the second door module is made of a relatively lightweight material as compared to the first door module.

3. The door of claim 1 , wherein a door trim is coupled to the second door module.

4. The door of claim 1 , wherein the first door module includes:
a door external panel disposed outside a passenger compartment;
a door internal panel disposed inside the passenger compartment and mounted to the door external panel;
a door frame coupled to a top portion of the door internal panel; and
an impact beam coupled to the door internal panel.

5. The door of claim 4 , wherein an opening portion is provided at a center portion of the door internal panel.

6. The door of claim 5 , wherein a reinforcing beam is coupled to the door internal panel in a form that traverses a portion of the opening portion of the door internal panel.

7. The door of claim 4 , wherein the door frame includes:
a second belt line portion formed to extend in a longitudinal direction of the vehicle; and
a first pillar portion extending at a first end portion of the second belt line portion in a height direction of the vehicle and a second pillar portion extending at a second end portion of the second belt line portion in the height direction of the vehicle,
wherein the first and second pillar portions are disposed forwards and rearwards of the second belt line portion along the longitudinal direction of the vehicle.

8. The door of claim 1 , wherein an internal space is formed between the first door module and the second door module when the second door module is coupled with the first door module and a door glass for opening or closing the door window is inserted into the internal space to be movable.

9. The door of claim 1 , wherein at least one door checker mounting boss for mounting a door checker is integrally formed to protrude toward an outside of a passenger compartment at an external surface of the second door module facing the outside of the passenger compartment.

10. The door of claim 9 , wherein at least one assemble protrusion inserted and assembled into an assemble hole formed in a door internal panel, is integrally formed to protrude toward the outside of the passenger compartment adjacent to the belt line of the external surface of the second door module.

11. The door of claim 10 , wherein an assemble boss for engaging with the door internal panel is integrally formed to protrude toward the outside of the passenger compartment at a lower portion of the external surface.

12. The door of claim 11 ,
wherein a protruding portion is formed at a lower portion of the door internal panel;
wherein the protruding portion is engaged with the assemble boss for assembling the door internal panel with the second door module; and
wherein an extending section is formed between the protruding portion and the door external panel.

13. The door of claim 9 , wherein at least one reinforcing rib is provided adjacent to the center pillar portion and the belt line position of the second door module;
the reinforcing rib includes a first reinforcing rib extending in a longitudinal direction of the vehicle and a second reinforcing rib extending in a height direction of the vehicle; and
the first and second reinforcing ribs are disposed to form a lattice pattern together.

14. The door of claim 13 , wherein at least one reinforcing portion is formed at the roof portion; and
the at least one reinforcing portion includes bosses, a third reinforcing rib extending radially from the bosses and a first reinforcing rib connecting the bosses.

15. The door of claim 9 ,
wherein an external surface of the center pillar portion is joined with a garnish;
wherein a receiving groove is formed between the garnish and the center pillar portion; and
wherein a door glass run is inserted into the receiving groove.

16. The door of claim 1 , wherein the reinforcement member includes a metal pipe or carbon fiber reinforced plastic core.
