Abstract

The utility model relates to a vehicle part, in particular to an outer handle with a locking mechanism for a vehicle door. The outer handle comprises a first pin shaft (2) fixed on a vehicle body (1), and an outer handle mechanism rotationally arranged on the first pin shaft (2) and used for opening the vehicle door, wherein the locking mechanism is arranged on the vehicle body (1); and when the outer handle mechanism is about to rotate relative to the first pin shaft (2) to open the vehicle door under the action of inertia force produced by vehicle side collision, the locking mechanism provides a limiting force for limiting the rotation of the outer handle mechanism for the outer handle mechanism through being propped against the outer handle mechanism under the action of the inertia force produced through vehicle side collision. By adopting the technical scheme, when vehicle side collision occurs, the outer handle mechanism tends to open the vehicle door under the action of the inertia force produced through the collision, but the rotation of the outer handle mechanism is restrained by the locking mechanism, thereby effectively preventing the vehicle door from being opened during the side collision; and due to the structural design, the torque of a torsion spring does not need to be increased, so that the hand feeling on opening the vehicle door is cannot be damaged.
