Abstract

A power supply apparatus for a door glass for a vehicle that includes the door glass installed on a door of the vehicle and configured to be movable in an upward and downward direction is provided, wherein an operation module is installed on the door glass to use power, and a power source part is installed on the door. The power supply apparatus includes a rail installed on the door and provided with a rail terminal to electrically conduct with the power source part, and a slider provided with a contactor slidably contacting the rail terminal and electrically conduct with the operation module, while moving in the upward and downward direction integrally with the door glass, wherein the contactor and the rail terminal maintain an electrically conductible state at all times regardless of a change in a position of the door glass.

First claim

What is claimed is:

1. A power supply apparatus for a door glass for a vehicle that comprises the door glass installed on a door of the vehicle, the door glass being configured to be movable in an upward and downward direction, wherein an operation module is installed on the door glass and configured to use power, and a power source part is installed on the door, the power supply apparatus comprising:
a rail installed on the door in the upward and downward direction of the door glass and provided with a rail terminal configured to electrically conduct with the power source part; and
a slider provided with a contactor slidably contacting the rail terminal and configured to electrically conduct with the operation module, while moving in the upward and downward direction integrally with the door glass,
wherein the contactor and the rail terminal are configured to maintain an electrically conductible state at all times regardless of a change in a position of the door glass.

2. The power supply apparatus of claim 1 , wherein:
the rail is installed on a door inner panel of the door in the upward and downward direction of the door glass; and
a part of the slider is installed inside the rail to be movable upward and downward.

3. The power supply apparatus of claim 1 , wherein:
the rail terminal is installed inside the rail in a longitudinal direction of the rail and is configured to electrically conduct with the power source part;
the contactor is configured to be electrically conductible with a slider terminal installed inside the slider; and
a portion adjacent to an end of the contactor is convex in shape and faces toward the rail terminal and elastically supported toward the rail terminal, such that the contactor is in contact with the rail terminal in a slidable state.

4. The power supply apparatus of claim 1 , wherein:
the rail has a part of an upper surface opened in a cross sectional view; and
the slider comprises a connector connected to the operation module and configured to be electrically conductible, a sliding part accommodated inside the rail, and a neck part connecting the connector to the sliding part and penetrating the upper surface of the rail.

5. The power supply apparatus of claim 4 , wherein:
the rail terminal is provided on an inner upper surface of the rail in a longitudinal direction of the rail; and
the contactor is installed on an upper surface of the sliding part.

6. The power supply apparatus of claim 4 , further comprising:
a slider cover covering the upper surface of the rail; and
a rubber made of an elastic material provided in a space between the slider cover and the upper surface of the rail in a longitudinal direction of the rail and installed to be in close contact with the neck part from the slider.

7. The power supply apparatus of claim 6 , further comprising a pair of rubbers facing each other in close contact with both side surfaces of the neck part, wherein a portion in which the slider is located is in close contact with both side surfaces of the neck part according to a sliding of the slider and in a portion in which the slider is not located, ends of the pair of rubbers are in close contact with each other to be watertight.

8. The power supply apparatus of claim 1 , further comprising a cable drawn out from the power source part to electrically conduct with the rail terminal, wherein a portion where the cable is drawn out from the power source part is surrounded by a grommet for watertightness.

9. The power supply apparatus of claim 1 , wherein the power source part is an inverter.

10. A power supply apparatus for a door glass for a vehicle, the vehicle comprising the door glass installed on a door of the vehicle and configured to be movable in an upward and downward direction, an operation module installed on the door glass and configured to use power, and a power source part installed on the door, the power supply apparatus comprising:
a rail installed on the door in the upward and downward direction of the door glass and provided with a rail terminal configured to electrically conduct with the power source part;
a slider provided with a contactor slidably contacting the rail terminal and configured to electrically conduct with the operation module, while moving in the upward and downward direction integrally with the door glass;
an upper rail cover installed above an inner panel of the door and coupled to an upper end of the rail; and
a lower rail cover installed below the upper rail cover in the inner panel of the door and coupled to a lower end of the rail,
wherein the contactor and the rail terminal are configured to maintain an electrically conductible state at all times regardless of a change in a position of the door glass.

11. The power supply apparatus of claim 10 , wherein the upper rail cover or the lower rail cover has a rail cover terminal inserted therein, the rail cover terminal configured to connect the power source part to the rail to be electrically conductible.

12. The power supply apparatus of claim 10 , wherein the lower rail cover has a rail cover terminal inserted therein, the rail cover terminal configured to connect the power source part to the rail to be electrically conductible and to electrically conduct the power source part and the rail terminal.

13. The power supply apparatus of claim 10 , wherein each of the upper rail cover and the lower rail cover is provided with a damper on one side thereof.

14. A power supply apparatus for a door glass for a vehicle, the vehicle comprising the door glass installed on a door of the vehicle and configured to be movable in an upward and downward direction, an operation module installed on the door glass and configured to use power, and a power source part installed on the door, the power supply apparatus comprising:
a rail installed on the door in the upward and downward direction of the door glass and provided with a rail terminal configured to electrically conduct with the power source part;
a slider provided with a contactor slidably contacting the rail terminal and configured to electrically conduct with the operation module, while moving in the upward and downward direction integrally with the door glass;
a holder accommodating a lower end of the door glass; and
a cursor fastened to the holder having a connector of the slider fitted therein, the cursor connected to the holder to be electrically conductible;
wherein the operation module is configured to electrically conduct with the holder, and the slider is configured to electrically conduct with the cursor; and
wherein the contactor and the rail terminal are configured to maintain an electrically conductible state at all times regardless of a change in a position of the door glass.

15. The power supply apparatus of claim 14 , wherein the holder comprises:
a glass accommodating part accommodating the lower end of the door glass; and
a holder terminal inserted into the holder and configured to electrically conduct with the operation module.

16. The power supply apparatus of claim 15 , wherein the cursor includes a socket into which the connector of the slider is inserted on one side thereof, the power supply apparatus further comprising a slider terminal installed inside the slider and a cursor terminal configured to electrically conduct the holder terminal inserted therein.
