Abstract

A vehicle door armrest apparatus is a door armrest provided on a luggage trim connected to a rear side of a door trim of a door of a vehicle, the vehicle door armrest apparatus including a housing portion on which an arm of a passenger is placed and which is provided on an internal side of the luggage trim and configured to rotate along an internal surface of the door trim, and a housing magnet operating to fix or release the housing portion to or from the door trim by generating or releasing a magnetic force depending on whether power is applied to the housing magnet with the door trim located between the housing magnet and a door magnet.

First claim

What is claimed is:

1 . A vehicle door armrest apparatus provided on a luggage trim connected to a rear side of a door trim in a door of a vehicle, the vehicle door armrest apparatus comprising:
a housing portion on which an arm of a passenger is to be placed and which is provided on an internal side of the luggage trim and configured to rotate along an internal surface of the door trim; and a housing magnet operating to fix or release the housing portion to or from the door trim by generating or releasing a magnetic force depending on whether power is applied to the housing magnet with the door trim located between the housing magnet and a door magnet.

2 . The vehicle door armrest apparatus of claim 1 , further including:
a return bracket portion housed in the housing portion, including a first portion fixed to the housing magnet, and rotating when the magnetic force is released to release the housing portion from the door trim; a button portion provided in the housing portion and coming into contact with a second portion of the return bracket portion to rotate the return bracket portion; and a rotation portion including one end portion rotatably coupled to the luggage trim, provided to cross the housing portion, and rotating so that the housing portion is positioned in a vertical direction of a vehicle body when the housing magnet is released from the door trim.

3 . The vehicle door armrest apparatus of claim 2 , wherein the housing portion includes:
an upper housing on which the arm of the passenger is to be directly placed, and a lower housing coupled to the upper housing and housing the housing magnet, the return bracket portion, the button portion, and the rotation portion therein.

4 . The vehicle door armrest apparatus of claim 2 , wherein the housing magnet faces the door magnet fixed on the door trim and is connected or disconnected to or from the door magnet by the magnetic force applied to or released from the door magnet.

5 . The vehicle door armrest apparatus of claim 2 , wherein the housing magnet is provided on an external cover guide that covers the housing magnet and is in contact with the return bracket portion to move forwards and backwards with respect to the door trim according to an operation of the return bracket portion.

6 . The vehicle door armrest apparatus of claim 5 ,
wherein a guide cap that moves forwards and backwards with respect to the door trim according to the operation of the return bracket portion, an internal cover guide that covers the guide cap, and a magnet cap that houses the housing magnet and passes through an opening of the housing portion, are provided on the external cover guide.

7 . The vehicle door armrest apparatus of claim 6 ,
wherein an internal spring is located between the housing magnet and the guide cap, and wherein an external spring is located between the lower housing and the internal cover guide.

8 . The vehicle door armrest apparatus of claim 4 , wherein the door magnet is provided on a fixing bracket fixed on the door trim.

9 . The vehicle door armrest apparatus of claim 4 ,
wherein the return bracket portion rotates in a horizontal direction of the housing portion around a rotation shaft inside the housing portion, wherein the return bracket portion includes a return bracket including a first portion which is in contact with the external cover guide and a second portion which is in contact with the button portion, and wherein a return spring that provides an elastic force to release an attractive force between the housing magnet and the door magnet when the magnetic force applied to the door magnet is released.

10 . The vehicle door armrest apparatus of claim 2 , wherein the button portion includes:
a push button which is provided to penetrate through one side portion of the housing portion, a button cover which is provided inside the housing portion and guides the push button, and a cap button which is provided on a side opposite to the push button and comes into contact with or is separated from the second portion of the return bracket portion.

11 . The vehicle door armrest apparatus of claim 10 , wherein a button spring that provides an elastic rebound force between the push button and the cap button is provided on an external circumferential surface of the push button.

12 . The vehicle door armrest apparatus of claim 11 , wherein a button socket which is in contact with the button spring while supporting the push button is located between the external circumferential surface of the push button and the button spring.

13 . The vehicle door armrest apparatus of claim 4 , wherein the rotation portion includes:
a rotation pin penetrating through a side portion of the housing portion, and a rotation spring provided on an external circumferential surface of the rotation pin to provide a rotation force to the rotation pin.

14 . The vehicle door armrest apparatus of claim 13 , wherein when a door opening signal is generated, the magnetic force applied to the door magnet is released, the return bracket portion rotates to release an attractive force between the door magnet and the housing magnet, and the rotation portion rotates so that the housing portion rotates to be positioned in the vertical direction of the vehicle body.

15 . The vehicle door armrest apparatus of claim 4 , wherein in response that the passenger pushes the button portion, the button portion pushes the second portion of the return bracket portion, and the return bracket portion rotates to release an attractive force between the housing magnet provided at the one portion of the return bracket portion, and the door magnet.

16 . A vehicle door armrest apparatus provided on a luggage trim connected to a rear side of a door trim in a door of a vehicle, the vehicle door armrest apparatus comprising:
a housing portion on which an arm of a passenger is to be placed and which is provided on an internal side of the luggage trim and configured to rotate along an internal surface of the door trim; a motor housed in the housing portion and driven when a door opening signal is generated to rotate the housing portion; and a rotation shaft including a first end portion rotatably coupled to the luggage trim, provided to cross the housing portion, and rotating so that the housing portion is positioned in a vertical direction of a vehicle body when the motor is driven.

17 . The vehicle door armrest apparatus of claim 16 , wherein the housing portion includes:
an upper housing on which the arm of the passenger is to be directly placed, and a lower housing coupled to the upper housing to form a space inside the housing portion.

18 . The vehicle door armrest apparatus of claim 16 ,
wherein a rotation gear is provided at a second end portion of the rotation shaft, and wherein the rotation gear gear-meshed with a motor gear provided on a shaft of the motor rotates together with the motor gear.

19 . The vehicle door armrest apparatus of claim 16 , wherein the motor is fixed inside the housing portion by a motor bracket in the housing portion.

20 . The vehicle door armrest apparatus of claim 16 ,
wherein position sensors that detect a position of the housing portion, and an electronic control unit which is configured to control rotation of the housing portion, are provided on an external side of the luggage trim.
