Abstract

A back beam for a vehicle having a charge and discharge function utilizing carbon fiber used as a reinforcing material in a back beam of a vehicle, may include a reinforced negative electrode portion formed of carbon fiber and formed to extend in the width direction of the vehicle, a positive electrode portion disposed opposite to at least a portion of the reinforced negative electrode portion, a solid electrolyte portion disposed between the reinforced negative electrode portion and the positive electrode portion to be in contact with the reinforced negative electrode portion and the positive electrode portion, and a molding portion formed of resin and surrounding the reinforced negative electrode portion, the positive electrode portion and the solid electrolyte portion.

First claim

What is claimed is:

1. A back beam for a vehicle having a charge and discharge function, the back beam comprising:
a reinforced negative electrode portion formed of carbon fiber, the reinforced negative electrode portion being formed to extend in a width direction of the vehicle;
a positive electrode portion disposed opposite to at least a portion of the reinforced negative electrode portion;
a solid electrolyte portion disposed between the reinforced negative electrode portion and the positive electrode portion and being in contact with the reinforced negative electrode portion and the positive electrode portion; and
a molding portion formed of resin, the molding portion surrounding the reinforced negative electrode portion, the positive electrode portion and the solid electrolyte portion.

2. The back beam according to claim 1 , wherein the reinforced negative electrode portion is implemented by manufacturing a multi-sheet such that reinforced fiber sheets, each including carbon fibers disposed in a direction different from directions in which the carbon fibers of other reinforced fiber sheets are disposed, are alternately and continuously disposed in a longitudinal direction thereof and are connected to each other, and by rolling the multi-sheet in a shape of a pipe having a multi-layer structure.

3. The back beam according to claim 2 , wherein a first distal end of the multi-sheet is rolled in a first direction and a second distal end of the multi-sheet is rolled in a second direction which is opposite to the first direction such that the first and second distal ends of the multi-sheet are rolled toward a center of the multi-sheet, respectively.

4. The back beam according to claim 1 , wherein the reinforced negative electrode portion includes a hollow hole formed therein in the width direction of the vehicle.

5. The back beam according to claim 1 , wherein the reinforced negative electrode portion and the positive electrode portion connected to a switch in which an alternator and an electronic device are connected to the switch in parallel, are selectively electrically-connectable by the switch to the alternator or the electronic device of the vehicle.

6. The back beam according to claim 5 ,
wherein, while the reinforced negative electrode portion and the positive electrode portion are electrically connected to the alternator, a charging operation is performed through the solid electrolyte portion, and
wherein, while the reinforced negative electrode portion and the positive electrode portion are electrically connected to the electronic device, power generated by a discharging operation performed through the solid electrolyte portion is supplied to the electronic device.

7. The back beam according to claim 1 , further including:
a resistive sensor connected to the reinforced negative electrode and the positive electrode to detect a resistance caused by the reinforced negative electrode portion, the positive electrode portion and the solid electrolyte portion,
wherein a collision of the vehicle is determined to occur based on a change in the resistance detected by the resistive sensor.
