Description

  The present invention relates to a vehicle handle device, and more particularly to a vehicle handle device including a door panel that is opened and closed by manual operation of a door handle.

  As is well known, a vehicle handle device for opening and closing the door panel by locking or unlocking the door lock mechanism of the door panel is incorporated in a vehicle such as an automobile.

  In recent years, for the purpose of improving the operability of the vehicle, this type of vehicle handle device has electronically unlocked the door lock mechanism when the owner (driver) approaches the vehicle, and the driver Has been proposed which has a function (smart entry function) for electronically locking the door lock mechanism when the vehicle is away from the vehicle.

  Such a vehicle handle device is provided with a function of mechanically performing locking and unlocking on the assumption that electronic locking and unlocking becomes impossible.

  As a conventional vehicle handle device of this type, for example, there is one provided with a door lock actuator that performs locking / unlocking by switching the connection of an actuator link mechanism housed inside (Patent Document 1).

  The vehicle handle device includes a handle link mechanism that generates a rotational motion by a pulling (pivoting) operation of a door handle, a handle rod that generates a downward linear motion by a rotational motion of the handle link mechanism, and a handle rod And a connecting lever mechanism that transmits the linear motion to the actuator link mechanism.

  Further, the vehicle handle device includes a cylinder lock housed in a door handle having a key rotor that is rotated by a rotation operation by inserting (inserting) a regular key (match key) into a key insertion hole that is always open. The cylinder lock rod rotates by the rotation of the key rotor of the cylinder lock, and the key lever mechanism transmits the rotation of the cylinder lock rod to the above-described actuator link mechanism.

  In such a vehicle handle device, when the key rotor is rotated in one direction from the neutral position by inserting and rotating the match key into the cylinder lock, the rotation is transmitted to the key lever mechanism via the cylinder lock rod. The operation of the key lever mechanism switches the on / off state of the actuator link mechanism in the door lock actuator, and the door lock mechanism is changed from the locked state to the unlocked state.

  Thereafter, when the door handle is operated in the direction to open the door panel, the operation of pulling out (turning) the door handle is transmitted to the handle rod via the handle link mechanism. When the handle rod linearly moves downward by the turning operation of the door handle, the linear motion is transmitted to the actuator link mechanism via the connecting lever mechanism. When the actuator link mechanism operates, the door lock mechanism is unlocked, and the door panel is opened.

On the other hand, when the key rotor rotates in the other direction from the neutral position by inserting and rotating the match key into the cylinder lock in the unlocked state of the door lock mechanism, this rotation is transmitted to the key lever mechanism via the cylinder locking rod. Then, the actuator link mechanism is operated by the operation of the key lever mechanism, and the door lock mechanism is changed from the unlocked state to the locked state.
