  • Patent number: 11939799
    Abstract: A door handle device for a vehicle includes a handle base, an operation handle, first and second link members disposed at an interval and rotatably pin-connected to the handle base respectively, and an electric actuator configured to rotatably drive the first link member. The operation handle is connected to the handle base so as to be able to protrude from an initial position to a use position. The operation handle is rotatably connected to end portions of the first and second link members. The handle base, the first and second link members, and the operation handle form a link mechanism in which the operation handle at the use position maintains a posture parallel to the initial position.

  • Publication number: 20240093536
    Abstract: A door handle device for a vehicle includes a handle base fixed to a door of a vehicle, and an operation handle rotatably coupled to the handle base. The operation handle includes a coupling protruding portion that is provided at an end portion on a rotation center side of the operation handle. The handle base includes an elastically deformable elastic piece that is adjacent to the coupling protruding portion. Movement of the operation handle toward a rotation tip end is restricted by elastically engaging a stopper protruding portion formed on any one of the coupling protruding portion and the elastic piece with a stopper fitting portion formed on the other by using elastic deformation of the elastic piece. Movement of the elastic piece in a disengagement direction of the stopper protruding portion is restricted by a clip mounted on the handle base.

  • Patent number: 11926196
    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.

  • Publication number: 20220195763
    Abstract: A vehicular handle device includes a handle body, a handle base, a door latch device, an electric actuator and a pushing member. The handle body is driven by the electric actuator from an initial position to a pop-up position, and manually operated to a latch operation position, thereby unlocking the door latch device. The handle body has a first end and a second end and power from the electric actuator is transmitted to the handle body from the first end. The pushing member is driven by the electric actuator and push the first end in a protruding direction in which the handle body protrudes from the handle base. The pushing member pushes the first end by an operation force in which an amount of change in a pushing amount of the first end gradually increases as the operation by the pushing member to push the first end proceeds further.

  • Publication number: 20220195762
    Abstract: A handle device for a vehicle includes a handle body, a latch release lever, a door latch device, an electric actuator and a lever push member. The handle body is driven from an initial position to a pop-up position by the electric actuator and is manually operated to a latch operation position. A latch of the door latch device is released by the latch release lever being driven to a latch release position. The lever push member rotates from an initial corresponding position and pushes the latch release lever toward the latch release position with an operation of the handle body. The lever push member is set with a moment of inertia to cancel an inertia force generated when a collision impact load is applied to the vehicle and to move the lever push member toward the latch release position.
