Removable inductive power transfer pad
First Claim
1. An apparatus comprising:
- a frame comprising an opening in a top surface of the frame;
a removable pad with an inductive power transfer (“
IPT”
) pad embedded therein, the IPT pad shaped to transmit power to a receiver pad positioned above the removable pad, the removable pad sized to conform to the opening, wherein the opening of the frame is shaped to support the removable pad and the removable pad and the opening are sized so that a top surface of the removable pad is substantially level with the top surface of the frame; and
a locking ring positioned around a perimeter of the top surface of the removable pad and one or more coupling mechanisms that couple the locking ring to the frame, wherein the locking ring exerts a downward force on the removable pad to secure the removable pad in the opening when the coupling mechanisms couple the locking ring to the frame, wherein the frame and the removable pad are notched to accommodate the locking ring and a top surface of the locking ring flush with the top surface of the frame and the top surface of the pad,wherein, when the frame is located in a roadway, the top surface of the pad exposed to vehicular traffic, the frame, removable pad mounted in the opening of the frame and locking ring are rated for vehicular traffic to drive over one or more of the frame, the removable pad and locking ring without damaging the frame, the removable pad or locking ring.

Abstract
An apparatus for a removable inductive power pad is disclosed. The apparatus includes a frame with an opening in a top surface of the frame, and includes a removable pad with an inductive power transfer (“IPT”) pad embedded therein. The IPT pad is shaped to transmit power to a receiver pad positioned above the removable pad. The removable pad is sized to conform to the opening, where the opening of the frame is shaped to support the removable pad and the removable pad and the opening are sized so that a top surface of the removable pad is substantially level with the top surface of the frame. When the frame is located in a roadway, the frame and removable pad mounted in the opening of the frame are rated for vehicular traffic to drive over the frame and/or the removable pad without damaging the frame or the removable pad.

17. An apparatus comprising:
-
a frame comprising an opening in a top surface of the frame; a removable pad with an inductive power transfer (“
IPT”
) pad embedded therein, the IPT pad shaped to transmit power to a receiver pad positioned above the removable pad, the removable pad sized to conform to the opening, wherein the opening of the frame is shaped to support the removable pad and the removable pad and the opening are sized so that a top surface of the removable pad is substantially level with the top surface of the frame, wherein the removable pad comprises a polymeric matrix and the IPT pad is embedded in the polymeric matrix, wherein the removable pad comprises a bottom plate, a bottom surface of the bottom plate comprising a bottom of the removable pad wherein the IPT pad is positioned within the polymeric matrix and the bottom plate is between the IPT pad and the bottom of the removable pad;one or more wire vias extending from a bottom of the removable pad positioned within the opening to an exterior edge of the frame, the bottom of the removable pad distal to the top surface of the removable pad, the one or more wire vias sized for wiring extending from the removable pad to one or more of at least the exterior edge of the frame and electrical devices within the frame, wherein the bottom plate comprises one or more openings coincident with the one or more wire vias positioned in the frame, one or more o-rings mounted between the removable pad and the bottom of the opening in the frame, wherein at least one o-ring surrounds each of the one or more wire vias and inhibits liquid from the top surfaces of the frame and removable pad from reaching the one or more wire vias when the removable pad is mounted in the opening of the frame; a locking ring positioned around a perimeter of the top surface of the removable pad and one or more coupling mechanisms that couple the locking ring to the frame, wherein the locking ring exerts a downward force on the removable pad to secure the removable pad in the opening when the one or more coupling mechanisms couple the locking ring to the frame, wherein the frame and the removable pad are notched to accommodate the locking ring and a top surface of the locking ring flush with the top surface of the frame and the top surface of the pad; and a dielectric grease that fills a space surrounding wiring within each of the one or more wire vias, wherein, when the frame is located in a roadway, the top surface of the pad exposed to vehicular traffic, the frame, removable pad and locking ring mounted in the opening of the frame are rated for motor vehicular traffic to drive over the frame, the removable pad and the locking ring without damaging the frame, the removable pad or locking ring. - View Dependent Claims (18)
