Abstract

A door handle assembly for a vehicle may include a door handle, a handle housing configured to provide an accommodation space for the door handle, a drive lever rotatably coupled to the handle housing and rotatably coupled to the door handle, and an actuator configured to transmit a driving force to the drive lever to deploy the door handle from the handle housing. In particular, the door handle is deployed from the handle housing as the drive lever is rotated with respect to the handle housing by the driving force of the actuator, and the door handle is rotated with respect to the drive lever.

First claim

What is claimed is:

1. A door handle assembly for a vehicle, comprising:
a door handle;
a handle housing configured to provide an accommodation space for the door handle;
a drive lever rotatably coupled to the handle housing and rotatably coupled to the door handle;
an actuator configured to transmit a driving force to the drive lever to deploy the door handle from the handle housing;
a support rod configured to move horizontally with respect to the drive lever and support an end of the door handle; and
a link configured to move the support rod while rotating with respect to the handle housing by the rotation of the drive lever,
wherein the door handle is deployed from the handle housing as the drive lever is rotated with respect to the handle housing by the driving force of the actuator, and the door handle is rotated with respect to the drive lever.

2. The door handle assembly of claim 1 , wherein when the door handle is accommodated in the handle housing, the door handle is disposed parallel to a vehicle door, and
wherein during deployment by the driving force of the actuator, the door handle becomes inclined with respect to the vehicle door, and upon completion of the deployment, the door handle is disposed parallel to the vehicle door.

3. The door handle assembly of claim 1 , wherein as the door handle is disposed inclined with respect to a vehicle door, a part of the door handle is discharged to exterior of the handle housing.

4. The door handle assembly of claim 1 , further comprising:
a first elastic member configured to generate an elastic force between the handle housing and the drive lever; and
a second elastic member configured to generate an elastic force between the drive lever and the door handle,
wherein in response to the driving force of the actuator being removed, the door handle is accommodated in the handle housing by the elastic force of the first elastic member, and
wherein in response to the drive lever being rotated by the driving force of the actuator, the door handle may be rotated with respect to the drive lever by the elastic force of the second elastic member.

5. The door handle assembly of claim 1 , wherein a vehicle door is unlocked in response to a force being exerted on the door handle in a direction away from the handle housing in a state where the door handle is deployed from the handle housing.

6. The door handle assembly of claim 5 , further comprising:
an unlocking unit connected to the drive lever and configured to unlock the vehicle door based on the rotation of the drive lever.

7. The door handle assembly of claim 1 , wherein in response to a force being exerted on the door handle in a direction away from the handle housing in a state where the door handle is supported by the support rod, the door handle is prevented from rotating with respect to the driving lever, and the force to the door handle is transmitted to the drive lever.

8. The door handle assembly of claim 1 , wherein in response to a force being exerted on one side of the door handle, a part of the door handle is deployed from the handle housing as the door handle is rotated with respect to the drive lever.

9. The door handle assembly of claim 1 , A door handle assembly for a vehicle, comprising:
a door handle;
a handle housing configured to provide an accommodation space for the door handle;
a drive lever rotatably coupled to the handle housing and rotatably coupled to the door handle; and
an actuator configured to transmit a driving force to the drive lever to deploy the door handle from the handle housing,
wherein the door handle is deployed from the handle housing as the drive lever is rotated with respect to the handle housing by the driving force of the actuator, and the door handle is rotated with respect to the drive lever, and
wherein the actuator comprises:
a drive motor configured to generate the driving force by rotation;
an output shaft configured to move axially by the driving force and press the drive lever;
an actuator housing configured to accommodate the drive motor and the output shaft; and
a position provision unit configured to provide a position of the output shaft with respect to the actuator housing.

10. The door handle assembly of claim 9 , wherein the position provision unit comprises:
a common electrode pin;
a first position electrode pin configured to indicate that the output shaft is in a position that does not press the drive lever in response to the first position electrode pin being electrically connected to the common electrode pin;
a second position electrode pin configured to indicate that the output shaft is in a position that presses the driving lever in response to the second position electrode pin being electrically connected to the common electrode pin; and
a connection pin included in the output shaft and configured to connect the first position electrode pin or the second position electrode pin to the common electrode pin.

11. A door handle assembly for a vehicle, comprising:
a door handle;
a handle housing configured to provide an accommodation space for the door handle;
a drive lever rotatably coupled to the handle housing and rotatably coupled to the door handle; and
an actuator configured to transmit a driving force to the drive lever to deploy the door handle from the handle housing,
wherein the door handle is deployed from the handle housing as the drive lever is rotated with respect to the handle housing by the driving force of the actuator, and the door handle is rotated with respect to the drive lever, and
wherein the door handle comprises:
a signal receiver configured to receive a signal associated with deployment of the door handle;
a weight body; and
a handle body configured to accommodate the signal receiver on one side thereof and the weight body on the other side thereof with respect to a rotation axis of the drive lever.

12. The door handle assembly of claim 11 , wherein the weight body decreases a moment of inertia of the door handle with respect to the rotation axis.

13. A door handle assembly for a vehicle, comprising:
a door handle;
a handle housing configured to provide an accommodation space for the door handle;
a drive lever rotatably coupled to the handle housing and rotatably coupled to the door handle; and
an actuator configured to transmit a driving force to the drive lever to deploy the door handle from the handle housing,
wherein the door handle is deployed from the handle housing as the drive lever is rotated with respect to the handle housing by the driving force of the actuator, and the door handle is rotated with respect to the drive lever,
wherein the door handle includes an optical device configured to emit light that corresponds to a vehicle signal received from the vehicle, wherein the optical device comprises:
a light source configured to irradiate the light;
a light guide configured to guide the light irradiated from the light source and emit the light to the handle cover;
a substrate configured to support the light source; and
a controller configured to control an operation of the light source,

wherein the light guide comprises:
a light incident part configured to receive the light from the light source, and
a light emission part configured to emit the light incident on the light incident part, and

wherein the light emission part comprises:
a light emission surface disposed towards the handle cover and configured to emit the light incident on the light incident part to the handle cover; and
a light diffusion surface provided on an opposite side of the light emission surface and configured to di
