Abstract
A protective arrangement for an electric vehicle charging system includes a floor unit forming a recess and a linkage disposed in the recess. The linkage is extendable from the recess from a stowed position to an extended position. A cleaning device is disposed to discourage accumulation of debris into the recess and on the linkage when the linkage is in the stowed position.
Claims7
A protective arrangement for an electric vehicle charging system, comprising:
- a floor unit forming a recess;
- a linkage disposed in the recess, the linkage being extendable from the recess from a stowed position to an extended position;
- a cleaning device disposed to discourage accumulation of debris into the recess and on the linkage when the linkage is in the stowed position;
- a connector disposed at an end of the linkage, the connector having sockets formed therethrough along opposite faces;
- wherein the cleaning device includes:
- a cleaning head disposed in the recess, the cleaning head including a plurality of cleaning brushes arranged on the cleaning head in a pattern that matches a pattern of the sockets in the connector;
- wherein the linkage is configured to bring the connector in close proximity with the cleaning head such that the sockets are aligned with the plurality of cleaning brushes;
- and
- actuators arranged to move the cleaning brushes within the sockets such that the cleaning brushes scrub each socket internally.

A method for protecting a charging arrangement for an electric vehicle, comprising:
- providing a floor unit forming a recess;
- providing a linkage disposed in the recess, the linkage being extendable from the recess from a stowed position to an extended position;
- and
- providing a cleaning device disposed to discourage accumulation of debris within the recess and onto the linkage when the linkage is in the stowed position;
- providing a connector disposed at an end of the linkage, the connector having sockets formed therethrough along opposite faces wherein the cleaning device includes:
- a cleaning head disposed in the recess, the cleaning head including a plurality of cleaning brushes arranged on the cleaning head in a pattern that matches a pattern of the sockets in the connector;
- and
- wherein discouraging accumulation of debris is accomplished by:
- bringing the connector in close proximity with the cleaning head using the linkage by moving the linkage from the stowed position to the extended position such that the sockets are aligned with the plurality of cleaning brushes;
- and
- moving the cleaning brushes into the sockets such that the cleaning brushes scrub each socket internally.
