Abstract

The application provides a door handle assembly for a vehicle door. The vehicle door has a door surface, and the door handle assembly includes a handle base, a handle, a drive, a handle shaft, and a transmission. The handle has a retracted position and an extended position. When the handle is in the retracted position, the handle is flush with respect to the door surface. When the handle is in the deployed position, the handle protrudes outwardly relative to the door surface. The handle shaft is configured to rotate under the drive of the drive device. The transmission connects the handle shaft to the handle so that the handle is movable in parallel relative to the handle base between a retracted position and an extended position under the drive of the handle shaft. When the handle is in the retracted position or the deployed position, the drive device is activated to deploy or retract the handle or to trigger unlocking of the vehicle door in response to the handle shaft rotating a predetermined angle when the operator pushes the handle.
