Abstract

The object of the invention is a device for recharging with energy a piece of storage equipment loaded on-board a vehicle comprising at least one power supply device external to the vehicle, at least one power collector fixed on the vehicle, the power collector comprising a central portion provided with at least one friction strip, intended for powering the vehicle when the vehicle is moving, the central portion being laterally extended with at least one horn formed in one piece in a metal material and forming an upper surface. At least one portion of the upper surface of the horn forms a contact area capable of directly coming into contact with a corresponding contact surface of the power supply device when the vehicle is at a standstill in a stop station in order to ensure energy transfer between the power collector and the power supply device via the contact area.

Claims

1. A device for recharging with energy a piece of storage equipment loaded on-board a vehicle comprising at least one power supply device external to the vehicle, at least one power collector fixed on the vehicle, the power collector comprising a central portion provided with at least one friction strip intended for powering the vehicle when the vehicle is moving, the central portion being laterally extended with at least one horn formed in one piece in a metal material and forming an upper surface, characterized in that at least one portion of the upper surface of the horn forms a contact area capable of directly coming into contact with a corresponding contact surface of the power supply device when the vehicle is at a standstill in a stop station in order to ensure energy transfer between the power collector and the power supply device via the contact area.

2. The recharging device according to claim 1, characterized in that the upper surface of the horn is continuous at least in and in the vicinity of the contact area.

3. The recharging device according to claim 1, characterized in that the horn is made in a material having high heat and electric conductivities, such as aluminum, copper, gold or silver.

4. The recharging device according to claim 1, characterized in that the position of the contact area along the upper surface of the horn is variable, the contact area being defined, in each stop station, as the area of the upper surface facing the corresponding contact surface of the power supply device when the vehicle is at a standstill in the stop station.

5. The recharging device according to claim 1, characterized in that the horn comprises a horizontal area substantially in the alignment of the central portion and an inclined area.

6. The recharging device according to claim 5, characterized in that the contact area is formed by a portion of the upper surface of the horizontal area and/or by a portion of the upper surface of the inclined area.

7. The recharging device according to claim 1, characterized in that the horn is assembled to the central portion.

8. The recharging device according to claim 1, characterized in that the power collector is a pantograph comprising two bows.

9. The recharging device according to claim 8, characterized in that each bow comprises a central portion laterally extended with two horns positioned on either side of the central portion, each horn being capable of cooperating with a power supply device.

10. The recharging device according to claim 1, characterized in that the horn is formed by means for guiding a catenary during the displacement of the vehicle.
