Abstract

An advertising panel for an electric vehicle is provided to facilitate advertising panel inserting and separating processes by rotatably holding a frame of the advertising panel around an upper bar of a holding member. An advertising panel for an electric vehicle includes a rectangular frame(30), an advertising panel member(40), and an LED(Light Emitting Diode) module(42). The frame is surrounded by upper and lower horizontal members and left and right vertical members. The upper and lower horizontal members include a front flange unit(31a), a wave unit(31b), and a support bracket unit(31c). The front flange unit restricts an external surface of the advertising panel member. The LED module, installed on a side end of a waveguide plate, is attached to the wave unit. The support bracket unit is arranged between the wave unit and the advertising panel member. The support bracket unit is protruded in a width direction of the advertising panel member and temporarily supports the advertising panel member during implementation. Plural planar springs are inserted into a space, formed inside the support bracket unit, along the length direction of the upper and lower horizontal members.

The present invention relates to an electric vehicle advertising panel, and more particularly to an electric vehicle advertising panel that facilitates the insertion and removal of the advertising panel body including the advertising sheet.

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, there is a problem in that the advertisement panel body composed of the light guide plate, the reflective sheet, and the advertisement sheet is not easy to be detached and not easily fixed, and thus easily detached.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide an advertisement panel for an electric vehicle that facilitates the insertion and detachment of the advertising panel body and prevents the separation of the inserted advertising panel body.

Advertisement panel for an electric vehicle according to the present invention for achieving the above object is provided with a rectangular frame coupled to the interior of the electric vehicle, the reflective sheet laminated to the rear portion of the light guide plate and the advertisement sheet laminated to the front portion of the light guide plate In the advertising panel for the electric vehicle having a panel fixed to the inside of the frame and a light emitting diode module having a plurality of light emitting diodes for emitting light and fixed to the side surface of the light guide plate, the frame is horizontally upper and lower A rectangular frame woven in a square by the member and the left and right vertical members, wherein the upper and lower horizontal members are in close contact with the front flange portion for restraining the outer surface of the advertising panel body, and the light emitting diode module installed on the side end of the light guide plate. The advertisement has a space between the web portion is constrained and the end back of the advertising panel body Protruding in the width direction of the panel body is made of a support bracket portion for temporarily supporting the installation of the advertising panel body, the space formed inside the support bracket portion to press the advertising panel body toward the front flange portion to apply an elastic force A plurality of leaf springs are inserted along the longitudinal direction of the upper and lower horizontal members.

The leaf spring is composed of a flat contact portion in close contact with the advertisement panel body, and a foot formed by bending at both ends of the flat contact portion.

The left and right vertical members are made of a fixing unit that is hinged to the seating plate so that the bottom of the advertising panel body is seated, and the advertising panel body is easily fitted into and fixed to the inside of the frame. The bottom surface of the seating plate is provided with a third protrusion with a rod of a circular cross section along the lengthwise direction of the left and right vertical members, and the bottom surface of the fixing table has a locking groove that is pivotally fitted to the rod of the third protrusion.
