1. A vehicular exterior door handle assembly, the vehicular exterior door handle assembly comprising:
a base portion disposed at a door handle region of a vehicle door of a vehicle;
a handle portion including a base end, a swing end, and a grasping portion disposed between the base end and the swing end, wherein the handle portion is movable relative to the base portion between a recessed position, where the handle portion is recessed at the base portion so as to be not graspable by a user, and a deployed position, where the handle portion protrudes outward from the base portion to be graspable by the user;
a crank that pivotally connects the base end of the handle portion to the base portion;
a bellcrank that is pivotally mounted at the base portion and that is coupled with a door latch of the vehicle;
a bellcrank link that pivotally connects the swing end of the handle portion to the bellcrank;
an actuator including a motor that is electrically operable in response to an input signal;
wherein, responsive to the input signal, the motor operates and the actuator engages a portion of the crank to impart pivotal movement of the crank to cause the crank to pivot relative to the base portion and move the handle portion from the recessed position toward the deployed position, and wherein, as the crank pivots to move the base end of the handle portion, the bellcrank link pivots relative to the bellcrank and the base portion to move the swing end of the handle portion;
wherein, when the handle portion is at the deployed position, the swing end of the handle portion is manually movable further outward from the base portion to move the bellcrank link outward from the base portion to impart pivotal movement of the bellcrank relative to the base portion to actuate the door latch;
wherein, when the handle portion is at the recessed position, the base end of the handle portion is manually movable inward to cause the swing end of the handle portion to move outward from the base portion to move the handle portion toward a manually deployed position without operation of the motor;
a crank locking mechanism that limits pivotal movement of the crank when the handle portion is in the manually deployed position;
wherein the crank locking mechanism comprises at least one protruding structure at the base end of the handle portion and at least one receiving structure at the base portion, and wherein the at least one receiving structure is configured to receive the at least one protruding structure when the base end of the handle portion is manually moved inward to cause the swing end of the handle portion to move outward toward the manually deployed position; and
wherein, when the handle portion is in the manually deployed position and is pulled by the user to open the vehicle door, the at least one protruding structure at the base end of the handle portion engages a portion of the at least one receiving structure at the base portion, and wherein engagement of the at least one protruding structure at the base end of the handle portion with the portion of the at least one receiving structure at the base portion precludes outward movement of the base end of the handle portion and pivotal movement of the crank.
