Vehicle door outer handle structure

摘要

A door opening prevention mechanism includes a lever member rotatable relative to a base member and swingable in a vehicle inside-and-outside direction, and an urging member to bias the lever member toward a set position. The lever member is held in the set position when an outer handle is located in a door closing position when a given inertial force does not act in a vehicle outside direction during a vehicle collision, and swings in the vehicle outside direction from the set position to be moved to a locked position against an urging force of the urging member when the inertial force acts. When the lever member is in the set position, movement of a connection lever in a door opening direction is allowed. When the lever member is located in the locked position, movement of the connection lever in the door opening direction is restricted.

主权项

1. A door outer handle structure for a vehicle, comprising:
a base member adapted to be fixed to a door of said vehicle; an outer handle provided to said base member so as to be swingable in a vehicle inside-and-outside direction and operable between a door closing position and a door opening position being away from said door closing position in a vehicle outside direction; a link mechanism adapted to be capable of transmitting a door opening operation of said outer handle as an unlatching operation of a door latch mechanism; and a door opening prevention mechanism configured to restrict actuation of a component of said link mechanism in a door opening direction due to a given first inertial force acting in said vehicle outside direction for said door in an event of collision of said vehicle, wherein: said link mechanism comprises:
a bell crank comprising an input arm portion and an output arm portion each being rotatably assembled to said base member so as to be swingable, said bell crank being engaged with a swinging portion of said outer handle at said input arm portion;a spring interposed between said bell crank and said base member, said spring being configured to bias said bell crank toward said door closing position; anda connection lever rotatably assembled to said output arm portion through intermediation of a connection shaft extending in a front-and-rear direction of said vehicle so as to be swingable under a state in which said door is closed, said connection lever being configured to enable an unlatching operation of said door latch mechanism through movement in said door opening direction; said door opening prevention mechanism comprises:
a lever member rotatably assembled to said base member so as to be swingable in said vehicle inside-and-outside direction; andan urging member configured to urge said lever member toward a set position; said lever member is set to be held in said set position when said outer handle is located in said door closing position under a state in which said first inertial force does not act, and to swing in said vehicle outside direction from said set position to be moved to a locked position against an urging force of said urging member when said first inertial force acts; an extended portion of said connection shaft is set to be movable relative to said lever member to allow said movement of said connection lever in said door opening direction when said lever member is located in said set position; and said extended portion of said connection shaft is set to come into contact with said lever member so that said relative movement of said extended portion is restricted when said lever member is located in said locked position, to thereby restrict said movement of said connection lever in said door opening direction, wherein, when said outer handle is operated between said door closing position and said door opening position under a state in which said first inertial force does not act, said lever member is set to come into slidable engagement with said extended portion of said connection shaft to be turned against said urging member, to thereby rotate by a predetermined amount with respect to said base member.
