A door handle assembly of a motor vehicle, having: a carrier able to be fastened on the inner side on a door or flap of the motor vehicle and constructed in a frame-like manner, a handle able to be arranged externally on the door or flap of the motor vehicle, which handle is able to be gripped behind by a user, a door lock of the door or flap of the motor vehicle, which can be actuated and opened both mechanically and also electrically, and a sensor electronics for the detection of an actuation of the handle brought about by a user, wherein a first longitudinal end of the handle is mounted pivotably on the carrier and a second longitudinal end of the handle is coupled to the carrier so as to be deflectable away from the carrier, wherein a mechanical retaining element, secured on the carrier, exerts onto the second longitudinal end of the handle a predetermined retaining force in the direction of the carrier and holds the handle in a non-deflected normal actuation position, wherein the sensor electronics on detection of an actuation of the handle by a user with a normal actuation force directed away from the carrier, which force is smaller than the predetermined restoring force, opens the door or flap electrically, and in so doing the handle remains arranged in its normal actuation position, and wherein the handle on an actuation of the handle with an emergency actuation force directed away from the carrier, which force is greater than the predetermined restoring force, is able to be deflected into an emergency actuation position, in which the deflection movement of the handle opens the door or flap mechanically, characterized in that a clamp element is displaceably mounted on the carrier and fixes on the carrier a lock cylinder or a lock cylinder dummy for the mechanical unlocking of a door lock of the door, wherein the handle in the non-deflected normal actuation position forms a cover for the lock cylinder or the lock cylinder dummy, and wherein the clamp element is movable between a mounting position, in which the clamp element is out of engagement with the lock cylinder or with the lock cylinder dummy, and an operating position, in which the clamp element fixes the lock cylinder or the lock cylinder dummy on the carrier. a carrier able to be fastened on the inner side on a door or flap of the motor vehicle and constructed in a frame-like manner, a handle able to be arranged externally on the door or flap of the motor vehicle, which handle is able to be gripped behind by a user, a door lock of the door or flap of the motor vehicle, which can be actuated and opened both mechanically and also electrically, and a sensor electronics for the detection of an actuation of the handle brought about by a user, wherein a first longitudinal end of the handle is mounted pivotably on the carrier and a second longitudinal end of the handle is coupled to the carrier so as to be deflectable away from the carrier, wherein a mechanical retaining element, secured on the carrier, exerts onto the second longitudinal end of the handle a predetermined retaining force in the direction of the carrier and holds the handle in a non-deflected normal actuation position, wherein the sensor electronics on detection of an actuation of the handle by a user with a normal actuation force directed away from the carrier, which force is smaller than the predetermined restoring force, opens the door or flap electrically, and in so doing the handle remains arranged in its normal actuation position, and wherein the handle on an actuation of the handle with an emergency actuation force directed away from the carrier, which force is greater than the predetermined restoring force, is able to be deflected into an emergency actuation position, in which the deflection movement of the handle opens the door or flap mechanically, characterized in that a clamp element is displaceably mounted on the carrier and fixes on the carrier a lock cylinder or a lock cylinder dummy for the mechanical unlocking of a door lock of the door, wherein the handle in the non-deflected normal actuation position forms a cover for the lock cylinder or the lock cylinder dummy, and wherein the clamp element is movable between a mounting position, in which the clamp element is out of engagement with the lock cylinder or with the lock cylinder dummy, and an operating position, in which the clamp element fixes the lock cylinder or the lock cylinder dummy on the carrier.
