Abstract

A door handle assembly for a vehicle includes a housing having an opening formed therein; a handle cover configured to be rotated inside the housing in a first direction to uncover the opening, or rotates in a second direction to cover the opening; a switch provided adjacent to the opening of the housing to allow a door of the vehicle to be opened in a state where the handle cover uncovers the opening; and a driving member that rotates the handle cover to uncover or cover the opening. In particular, the driving member allows the handle cover to be rotated with respect to a first rotation axis, and at the same time, a second rotation axis, which is spaced apart from the first rotation axis and revolves around the first rotation axis, such that the handle cover is moved by both a translational motion and a rotational motion.

First claim

What is claimed is:

1 . A door handle assembly for a vehicle comprising:
a housing having an opening formed on one side; a handle cover configured to be rotated inside the housing in a first direction to uncover the opening, or to be rotated in a second direction, which is opposite from the first direction, to cover the opening; a switch provided adjacent to the opening of the housing, the switch being configured to cause a door of the vehicle to be opened in a state where the handle cover uncovers the opening; and a driving member that rotates the handle cover to uncover or cover the opening, wherein the driving member allows the handle cover to be rotated with respect to a first rotation axis, and at the same time, a second rotation axis, which is spaced apart from the first rotation axis and revolves around the first rotation axis, such that the handle cover is moved by both a translational motion and a rotational motion.

2 . The door handle assembly of claim 1 , wherein the driving member comprises:
a rotation shaft that rotates about the first rotation axis in response to a driving force transmitted to a proximate end thereof; a guide gear fixed inside the housing and having a first gear formed on an outer peripheral surface thereof; a link member, a first side of which is coupled to a distal end of the rotation shaft and such that the rotation shaft and the link member rotate simultaneously; and a revolution shaft, in which a second gear is provided at one end to mesh with the first gear, that rotates about the second rotation axis and revolves around the rotation shaft.

3 . The door handle assembly of claim 1 , wherein a rotation angle of the revolution shaft is formed to be greater than a rotation angle of the rotation shaft.

4 . The door handle assembly of claim 1 , wherein the driving member is disposed on one side or both sides of the handle cover.

5 . The door handle assembly of claim 2 , wherein the handle cover comprises:
a cover portion formed to correspond to a shape of the opening and configured to cover the opening; and an extension portion provided at rear of the cover portion to allow an interior space of the housing to be communicated with the opening in response to the cover portion being rotated away from the opening.

6 . The door handle assembly of claim 5 , wherein the handle cover further comprises:
a reflective cover made of a transparent or translucent material and provided to connect the cover portion and the extension portion, wherein the reflective cover is configured to be visible through the opening as a curved surface; and a lighting portion that is disposed at an inside space between the cover portion and the reflective cover and irradiates light to be transmitted through the reflective cover when the opening is opened.

7 . The door handle assembly of claim 6 , wherein the switch is disposed in an upper region of the opening within the housing, and
wherein, when the opening is opened, the light is irradiated from the lighting portion to illuminate an operating region of the switch.

8 . The door handle assembly of claim 1 , further comprising:
a manual opening module provided on one side of the opening inside the housing, wherein, in response to power to the driving member being cut off, the manual opening module allows the opening to be manually opened.

9 . The door handle assembly of claim 8 , wherein the manual opening module comprises:
a button portion to allow a user to press it; and a linkage arm that rotates to unlock a door latch in response to the button portion being pressed.

10 . The door handle assembly of claim 2 , wherein the driving member further comprises:
an elastic member that is coupled to the rotation shaft and provides an elastic restoring force to the link member.
