door handle assembly

Abstract

The invention relates to a coupling device for a vehicle door handle (1) having a handle lever (3) which can be moved in its flush position flush with the outer surface of the door panel (100) by means of an electric motor (7) between a ready position extended and graspable by the user, and an inward click position in which the preloaded push-push unit (13) is released to place the handle lever in the ready position without actuating the motor, The coupling device comprises: a central shaft (31) connecting the handle lever (3); rotationally coupled with the central shaft and via a push-push lever (45) and a push-push lever when the handle lever is pushed inwards to the click position The unit interacts to release the preloaded push-push unit and pushes the lever to the push-push lever cylinder (29) in the ready position; is rotationally coupled with the central shaft and interacts with the motor to make the handle when the motor is actuated Coupling gear (27) for moving the lever from the flush position to the ready position, wherein one of the coupling gear and the push-push lever cylinder comprises an axial protrusion (41) and the other comprises a circular arc-shaped recess (43) , the axial protrusion engages in the arc-shaped recess to allow the coupling gear and the push-push lever cylinder to freely face each other within an angular range corresponding at least to the angular distance between the ready position and the click position of the handle lever rotate.

Description

technical field [0001] The present invention relates to a vehicle door assembly, particularly of the type having a flush door handle lever. Background technique [0002] Such vehicle door handle assemblies include an electric motor that, when actuated, moves a handle lever between a flush position and a ready position. In the flush position, the handle lever is flush with the outer surface of the door body. In the ready position, the handle lever protrudes from said outer surface so as to be graspable by a user. [0003] Once the user has grasped the handle lever in its ready position, he can unlock the door by pulling the lever to a further protruding unlocking position, where the door handle lever interacts with the latch mechanism (via Bowden cables, Rotate the pin or gear mechanism) and unlock the door. [0004] When the user releases the handle lever, the handle lever spring brings the handle lever back to its ready position. The motor also moves the handle lever fr...

Problems solved by technology

[0008] In the case of irreversibility due to increased friction due to temperature, the resulting reverse actuation may lead to damage or even rupture of the reduction mechanism, making it possible during manual back-up opening as well as when normal electric actuation is resumed (e.g. in After recharging the battery or removing the motor fault) endangers the operation of the entire door handle
