Description

  The present invention relates to a vehicle door handle device having a lever-shaped handle body on the outside of a door outer plate, and in particular, due to a side collision or the like at a vehicle door having such a vehicle door handle device. The present invention relates to a vehicle door handle device having a door opening suppression mechanism that operates to suppress opening of a vehicle door when a predetermined impact force (acceleration) is applied.

  In general, when an impact load (acceleration) is input to a vehicle door having a door handle device due to, for example, a side collision, the input load of the input load is applied to the handle body attached to the vehicle door. By the reaction, a force (acceleration) that opens the vehicle door, that is, pushes the handle body to the outside of the door acts. In response to such an action of force that opens the vehicle door, the handle body is engaged with the hook portion of the handle body in the conventional one, for example, as described in JP-A-2008-127888. There is a crank arm that controls the operation of the lock arm, and a lock pin is engaged with a crankshaft serving as a rotational fulcrum of the crank arm according to the input of the impact load. The operation of the lock pin, specifically, the engagement (fitting) of the lock pin with the crankshaft suppresses the rotational movement of the crankshaft, and the movement of the hook portion, specifically, the outside of the door of the handle body. On the other hand, movement to the opposite side is prevented. In this way, the door body is prevented from being opened in response to the input of the impact load on the side surface of the door. That is, the emergency lock function is exhibited with respect to the impact load input to the door side surface.

By moving in the opposite direction, it engages with a protruding stopper provided on the side surface of the crank arm. In particular, in the present invention, since the slider having a predetermined inertial mass slides in a direction perpendicular to the door valgus surface, the direction of the reaction force with respect to the impact load can be changed. Matches the direction of slide movement. As a result, the slider reacts sensitively to the impact load, reacts immediately to the input of the impact load (acceleration), operates the stopper mechanism, and performs the lock function well. Will be able to. The engaging action between the stopper and the slider prevents the crank arm from rotating, and the engaging action between one end of the crank arm and the hook portion formed on the handle body is maintained. It becomes. In this way, the emergency lock function of the door handle device is exhibited with respect to the input of the impact load. In addition, since the mechanism that exhibits such an emergency lock function is not formed by a notch or the like provided in a part of the crank arm as in the conventional one, an emergency lock mechanism, There is no problem such as insufficient strength of the door handle device. Furthermore, the operation position of the emergency lock function can be set freely by positioning the protruding stopper formed on the side of the crank arm, so that the operation position for the emergency lock function can be set freely. The degree will be increased. As a result, the degree of design freedom for setting the emergency lock mechanism is increased.

  Next, in the second invention which is the invention described in claim 2, in addition to the first invention, the following effects are further exhibited. That is, in this device, the slider has a cylindrical shape and a spring for controlling the operation of the slider is installed in the slider. It is cut off from dust and the like, and foreign matter is prevented from entering between the spring coils. As a result, malfunction of the emergency lock mechanism can be prevented.
