Actuating drive for a motor vehicle

An actuator, comprising

• a locking bar that can be retracted and extended by means of a spindle,
• an electric drive unit for retracting and extending the locking bar,
• a dust-tight and moisture-tight inner space in which the drive unit is located,
• with a manually actuatable emergency release device comprising a lever and an extension arm connected with the locking bar, and
• a guide channel for the lever disposed outside of the inner space,
• the lever comprising a bolt which can be partially pushed through a stationarily disposed sealing ring in order to then arrive in an inner space sealed in a dust-tight and moisture-tight manner,
• with a sealing ring, which is disposed in a groove and extends peripherally around the locking bar, for a tight connection between the actuator and the component connected to the actuator,
• the sealing ring being inserted into a peripherally extending groove of the housing of the actuator,
• with a dust-tight and moisture-tight housing,
• a single-walled wall portion of the housing being formed by a membrane consisting of a flexible material,
• the membrane being configured in a wavy manner for pressure and/or volume equalization,
• with a stationarily disposed sealing ring that extends peripherally around the locking bar and adjoins the locking bar tightly, for a tight connection between the locking bar and the housing,
• the actuator being attached to a car body member for an electric vehicle which comprises:
• a charging socket for charging a battery of an electric vehicle,
• a first lid for covering an opening of the housing of the charging socket, and
• a second lid for covering the first lid,
• the actuator being attached in such a way that the second lid can be locked by means of the actuator,
• the first lid being smaller than the second lid.
