Abstract

A door armrest structure of a vehicle includes: an armrest pivot including a first end portion rotatably coupled to the door internal panel, and a second end portion extending into the vehicle body through the door trim; an armrest including a first end portion connected to the second end portion of the armrest pivot and operating to be rotated according to rotation of the armrest pivot; a drive motor connected to the armrest pivot and operating to rotate the armrest pivot according to an opening signal or a closing signal of the door; and a supporting pin that supports the second end portion of the armrest to be fixed when the armrest rotates and forms an angle which is parallel to a bottom surface of the vehicle body.

First claim

What is claimed is:

1. A door armrest structure of a vehicle as a door armrest structure provided to a door internal panel configuring a door for opening or closing a door opening formed in a vehicle body and a door trim covering the door internal panel, the door armrest structure comprising:
an armrest pivot including a first end portion rotatably coupled to the door internal panel, and a second end portion extending into the vehicle body through the door trim;
an armrest including a first end portion connected to the second end portion of the armrest pivot and operating to be rotated according to rotation of the armrest pivot;
a drive motor connected to the armrest pivot and operating to rotate the armrest pivot according to an opening signal or a closing signal of the door; and
a supporting pin that supports the second end portion of the armrest to be fixed when the armrest rotates and forms an angle which is parallel to a bottom surface of the vehicle body.

2. The door armrest structure of claim 1 , wherein the supporting pin is provided on a rear luggage trim of the vehicle body.

3. The door armrest structure of claim 1 , wherein the second end portion of the armrest is provided with a fixing protrusion supported to the supporting pin.

4. The door armrest structure of claim 1 , wherein the first end portion of the armrest pivot is rotatably coupled to the door internal panel by an armrest pivot fixing pin.

5. The door armrest structure of claim 1 , wherein in an opening process or a closing process of the door, the armrest is rotated so that the second end portion of the armrest is disposed to be rotated in a direction away from the bottom surface of the vehicle body.

6. The door armrest structure of claim 5 , wherein the armrest is configured as a grip handle when the armrest is rotated and the second end portion of the armrest is disposed to be rotated in a direction away from the bottom surface of the vehicle body.

7. The door armrest structure of claim 1 , wherein the door trim has an armrest seating portion that provides a rotation space for the armrest at a connection point of the armrest pivot and the armrest.

8. The door armrest structure of claim 7 ,
wherein the armrest seating portion includes a cutting portion, and
wherein when the armrest rotates and the second end portion of the armrest rotates in a direction away from the bottom surface of the vehicle body, the cutting portion of the armrest seating portion limits rotation of the armrest.

9. The door armrest structure of claim 1 , wherein in a closing state of the door, the armrest rotates so that the second end portion of the armrest is supported to the supporting pin.

10. The door armrest structure of claim 9 , wherein when the armrest is rotated and the second end portion of the armrest is supported to the supporting pin, the armrest is configured for mounting an arm of an occupant.

11. The door armrest structure of claim 10 , wherein an upper surface of the armrest is disposed to be at a same surface as an external upper surface of an armrest seating portion of the door trim.

12. The door armrest structure of claim 11 , wherein the armrest seating portion provides a rotation space for the armrest at a connection point of the armrest pivot and the armrest.

13. The door armrest structure of claim 12 ,
wherein the armrest seating portion includes a cutting portion, and
wherein when the armrest rotates and the second end portion of the armrest rotates in a direction away from the bottom surface of the vehicle body, the cutting portion of the armrest seating portion limits rotation of the armrest.

14. The door armrest structure of claim 1 , wherein an end portion of the armrest is formed of a ‘L’ shape.

15. The door armrest structure of claim 1 , wherein the drive motor is a cinching motor that assists in a locking of the door and rotation of the armrest.

16. The door armrest structure of claim 15 , wherein the drive motor includes a latch driving cable and an armrest driving cable respectively connected to a latch provided on a hinge side of the door and the armrest pivot to transmit a driving torque to the latch and the armrest pivot.
