1. A trailer coupling assembly (300) connecting a support structure (130) of a vehicle (100) or a support structure (210) of a trailer (200) to a tow bar (110) or a connection head/trailer hitch (211), said trailer coupling assembly (300) comprising:
an intermediate connection device (310) having a first end directly or indirectly coupled to the support structure (130, 210) and a second end;
a first additional intermediate connecting device (320) having a first end coupled to the second end of the intermediate connecting device (310) and a second end coupled to the tow bar (110) or connection head/trailer hitch (211), said first additional intermediate connecting device (320) being rotatable about a horizontal axis at the second end of the intermediate connecting device (310);
the intermediate connecting device (310) including a motor and drive controllable to move the first additional intermediate connecting device (320) and the tow bar (110) or connection head/trailer hitch (211) coupled thereto in a vertical direction relative to the vehicle (100) or trailer (200) by rotating the first end of the first additional intermediate connecting device (320) about the horizontal axis; and
the first additional intermediate connecting device (320) including a motor and drive controllable to move the tow bar (110) or connection head/trailer hitch (211) coupled thereto in a longitudinal direction relative to the vehicle (100) or trailer (200), said first additional intermediate connecting device (320) having an elongated body (321) configured to receive one end of the tow bar (110) or connection head/trailer hitch (211), and said drive is coupled to said motor such that rotation of said drive in a first direction extends the tow bar (110) or connection head/trailer hitch (211) from the elongated body (321) and rotation of the drive in a second direction opposite the first direction retracts the tow bar (110) or connection head/trailer hitch (211) toward the elongated body (321).
