Description

Lighting System and Lighting Method for Charging Port of Electric Vehicle The present disclosure relates to an electric vehicle, and more specifically, to a system and method for illuminating a charging port of an electric vehicle. Generally, electric vehicles are charged by plugging a charger into a charging port. It is desirable to provide a lighting system that illuminates the charging port so that the charger can be easily plugged into the charging port at night. Previously, the lighting position was located very close to the charging port, such as above the charging port, which resulted in disadvantages such as a narrow lighting range or difficulty in replacing the lamp fixture. Therefore, if an electric vehicle charging port lighting system that illuminates a wider area and is easy to maintain is provided, it is expected that the usability of electric vehicles will be improved. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs. FIG. 1 is a drawing illustrating the external configuration of a charging port lighting system of an electric vehicle according to an embodiment of the present disclosure. FIG. 2 is a partially exploded perspective view of the exterior configuration of a charging port lighting system of an electric vehicle according to an embodiment of the present disclosure. FIG. 3 is an exploded perspective view of a charging port lighting system of an electric vehicle according to an embodiment of the present disclosure. FIG. 4a illustrates a hinge body and a first arm of a hinge mechanism according to an embodiment of the present disclosure, according to direction A of FIG. 3. FIG. 4b illustrates a second arm of a hinge mechanism according to an embodiment of the present disclosure, according to direction B of FIG. 3. FIGS. 5a and 5b are perspective views of a hinge mechanism of an electric vehicle according to an embodiment of the present disclosure, viewed from the inside of the vehicle. FIG. 6a is a perspective view illustrating the sliding coupling of a first arm and a first cover in a hinge mechanism according to an embodiment of the present disclosure. FIG. 6b is a side view illustrating the sliding coupling of a second arm and a second cover in a hinge mechanism according to an embodiment of the present disclosure. FIG. 7 is a block diagram illustrating the control configuration of a charging port lighting system of an electric vehicle according to an embodiment of the present disclosure.
