The present invention relates to a fixing device for an electric vehicle advertising panel, and more particularly, to a fixing device for an electric vehicle advertising panel that can facilitate the wiring and repair of the inside of the advertising panel installed in the electric vehicle.

In general, the conventional advertising panel for electric vehicles was only a frame form for posting an advertisement sheet, but recently, various types of advertisement panels with improved visibility by using LCD (LCD) billboard, fluorescent lamp or cold cathode fluorescent lamp (CCFL) as a light source. The advertising panel of the frame type has low visibility and low advertising effect.When the LCD panel or fluorescent lamp is used as a light source, it is thick and has high power consumption. In the case of using a cold cathode fluorescent lamp (CCFL) as a light source, power consumption is small, but a high voltage power supply is required.

In order to solve the above problems, it is possible to turn on the light with low voltage by using light emitting diode (LED) and minimize the power consumption, and the brightness is very excellent. It is disclosed in Utility Model No. 20-0420932.

As shown in Registration Utility Model No. 20-0420932, an electric vehicle advertising panel 10 using a light emitting diode (LED) is fixed to the inner wall 11 of the electric vehicle by a fastening member (not shown), as shown in FIG. A light emitting diode having a rectangular frame 12, a light guide plate 13 fixed inside the frame 12, and a plurality of light emitting diodes emitting light, and fixed to a side surface of the light guide plate 13; A module 14, a reflective sheet 15 laminated on the rear surface of the light guide plate 13 and reflecting light diffused through the light guide plate 13 forward; and the light guide plate as a sheet printed with required characters and images. Advertisement sheet 16 laminated on the front portion of the 13 and the power supply unit 17 for supplying power to the LED module 14 is provided. The power supply unit 17 is a converter for converting AC power to DC power.

2 shows a state in which the electric vehicle advertising panel 10 configured as described above is installed above the door D inside the electric vehicle.

However, in the conventional electric vehicle advertising panel configured as described above, since the frame 12 is directly fixed to the inner wall 11 of the electric vehicle by a fastening member, when wiring or rewiring inside the advertising panel or the power supply unit. In the case of repairing, there is a problem in that it is inconvenient to work because the fastening member must be released to release the entire frame 12.
