Abstract

A handle device for a vehicle includes a handle body, a latch release lever, a door latch device, an electric actuator and a push portion forming member. The handle body moves between an initial position, a pop-up position and to a latch operation position. The door latch device is released by the latch release lever rotating to a latch release position. The push portion forming member moves from an initial corresponding position to a latch operation corresponding position and has a lever push portion to, when the push portion forming member is at the latch operation corresponding position, rotate the latch release lever to the latch release position. The push portion forming member has a restriction wall to prevent, when the push portion forming member is between the initial corresponding position and a pop-up corresponding position, the latch release lever from rotating toward the latch release position.

First claim

What is claimed is:

1. A handle device for a vehicle, comprising:
a handle body;
a latch release lever;
a door latch device configured to be provided in a door of the vehicle;
an electric actuator; and
a push portion forming member,
wherein the handle body is configured to be driven from an initial position to a pop-up position by the electric actuator and is manually operated further to a latch operation position beyond the pop-up position,
wherein the door latch device is configured such that a latch of the door latch device is released by the latch release lever rotating to a latch release position,
wherein the push portion forming member is configured to move from an initial corresponding position to a latch operation corresponding position in accordance with an operation of the handle body, the initial corresponding position corresponding to the initial position of the handle body and the latch operation corresponding position corresponding to the latch operation position of the handle body,
wherein the push portion forming member has a lever push portion configured to, when the push portion forming member is located at the latch operation corresponding position, push and rotate the latch release lever to the latch release position,
wherein the push portion forming member has a restriction wall,
wherein the restriction wall prevents, when the push portion forming member is located at a position between the initial corresponding position and a pop-up corresponding position corresponding to the pop-up position of the handle body, the latch release lever from rotating toward the latch release position, and
wherein the push portion forming member further comprises a weight portion disposed proximal the lever push portion configured to set a magnitude of the moment of inertia of the push portion forming member such that, when an impact force due to a collision is applied to the vehicle, an inertia force generated in the push portion forming member toward an operation direction of the latch release lever is canceled and rotation of the latch release lever in the operation direction is not generated.

2. The handle device according to claim 1 , further comprising:
a handle base;
a drive arm; and
an operation link,
wherein the drive arm is configured such that one end of the drive arm is rotatably connected to one end of the handle body, the other end of the drive arm is rotatably connected to the handle base, and the drive arm is driven by the electric actuator,
wherein the operation link forms a link mechanism together with the handle body, the drive arm, and the handle base,
wherein one end of the operation link is rotatably connected to the other end of the handle body, and the other end of the operation link is rotatably connected to the handle base, and
wherein the operation link includes the push portion forming member.

3. The handle device according to claim 2 ,
wherein a connection portion between the operation link and the handle body has a sliding pair, and
wherein the handle body is configured to move from the pop-up position to the latch operation position by a rotation operation of the handle body about a rotation center of the handle body with respect to the drive arm.

4. The handle device according to claim 1 ,
wherein the lever push portion does not contact the latch release lever when the push portion forming member is located at the position between the initial corresponding position and the pop-up corresponding position.

5. The handle device according to claim 1 , further comprising:
an inertia stopper,
wherein the inertia stopper is configured to, when a collision impact load is applied, rotate to a stop position and prevent the push portion forming member from moving toward the latch operation corresponding position.
