## 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; and where the second door module is made of a relatively lightweight material as compared to the first door module and a reinforcement member is coupled along external edge portions of the first door module and the second door module, reducing weight and cost of the door of the vehicle.

## Claims

### Claim 1

A door of a vehicle, the door comprising:
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 is made of a relatively lightweight material as compared to the first door module,
wherein a reinforcement member is coupled along external edge portions of the first door module and the second door module,
wherein the first door module includes:
a door external panel disposed toward an outside of a passenger compartment;
a door internal panel disposed toward an internal to the passenger compartment;
a door frame connected to an upper portion of the door internal panel; and
an impact beam connected to the door internal panel, and
wherein the door frame includes two pillar portions extending in a height direction of the vehicle at a front side and a rear side of the vehicle along a longitudinal direction of the vehicle.

### Claim 2 (depends on 1)

The door of the vehicle of claim 1,
wherein the first door module is formed of metal material, and
wherein the second door module is formed of plastic material.

### Claim 3 (depends on 1)

The door of the vehicle of claim 1,
wherein a door trim is coupled with the second door module.

### Claim 4 (depends on 1)

The door of the vehicle of claim 1,
wherein the door internal panel is provided with an opening portion at a center thereof.

### Claim 5 (depends on 4)

The door of the vehicle of claim 4,
wherein a reinforcing beam is integrally coupled with the door internal panel to cross a part of the opening portion of the door internal panel.

### Claim 6 (depends on 1)

The door of the vehicle of claim 1,
wherein the reinforcement member forms a closed loop.

### Claim 7 (depends on 1)

The door of the vehicle of claim 1,
wherein the reinforcement member has a pipe shape.

### Claim 8 (depends on 1)

The door of the vehicle of claim 1,
wherein the reinforcement member is formed of steel material having a rigidity higher than a rigidity of the second door module.

### Claim 9 (depends on 1)

The door of the vehicle of claim 1,
Wherein the door internal panel includes a protruding portion which is formed to protrude from a portion of the door internal panel toward the passenger compartment to form a predetermined space, and
wherein the reinforcement member is fastened to the protruding portion in the determined space of the protruding portion.

### Claim 10 (depends on 9)

The door of the vehicle of claim 9,
wherein an end of the protruding portion and an end of the door external panel are connected to form the predetermined space therebetween, and
wherein the reinforcement member is positioned in the predetermined space.

### Claim 11 (depends on 9)

The door of the vehicle of claim 9,
wherein a nut is connected to the reinforcement member via welding, and
wherein a bolt is configured to penetrate the protruding portion to be fastened to the nut.

### Claim 12 (depends on 9)
