Door handle assembly for vehicle

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 mechanism that rotates the handle cover to uncover or cover the opening,

wherein the driving mechanism comprises:

an actuator that generates a driving force for rotating the handle cover;

a rotation shaft that rotates about a first rotation axis in response to the 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; and

a revolution shaft, in which a second gear is provided at one end to mesh with the first gear, that rotates about a second rotation axis and revolves around the rotation shaft,

wherein the driving mechanism allows the handle cover to be rotated with respect to the first rotation axis, and at the same time, the 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 mechanism further comprises:

a link member, a first side of which is coupled to a distal end of the rotation shaft such that the rotation shaft and the link member rotate simultaneously.

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 mechanism is disposed on one side or both sides of the handle cover.

5 . The door handle assembly of claim 1 , 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 a state in which power to the driving mechanism is cut off, a user is allowed to forcibly rotate the handle cover to expose the opening and reach the manual opening module.

9 . The door handle assembly of claim 8 , wherein the manual opening module comprises:

a button portion to allow the 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 mechanism further comprises:

an elastic member that is coupled to the rotation shaft and provides an elastic restoring force to the link member.
