Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a molding structure for an automobile,
In particular, the present invention relates to glitter molding suitable for guard molding.

When a car is parked on the street at night, the driver of another car may miss the parked car and cause a collision. For this reason, in the past, as shown in FIGS. 1 and 2, a guard molding A fixed to the outer panel of the vehicle body is provided with light reflection measures to prevent collisions when parking at night. That is, in FIG. 2, a reflective tape 3 that reflects light toward the light source is attached to the surface of a guard molding body 2 fixed to a vehicle body outer panel B with a double-sided adhesive tape 1. The presence of a parked car is notified by the reflected light from 3. However, this reflective tape 3
The contact accident prevention measures based on the assumption that the vehicle is illuminated by a light source, so when the car is driving with the lights turned off or when parking near a bend, the light from the headlights should not reach the reflective tape 3 sufficiently. This was insufficient as a measure to prevent accidents when parking at night, as sufficient reflected light could not be obtained. (Jitsukai 55-176846
The present invention proposes a molding structure that can reliably recognize the existence of a parked car even from a distance, in order to prevent the above-mentioned conventional accidents during night parking. The present invention incorporates a surface illuminant inside the molding body, and makes the illuminant shine when the vehicle is parked at night, thereby recognizing the presence of a parked car, and preventing the surface illuminant from being exposed to external forces. We propose a structure that can provide sufficient protection.

Embodiments of the present invention will now be described in detail with reference to FIGS. 3 to 6.

3 to 6 show embodiments of the present invention,
The molding body 2, which is resin-molded to have a "C"-shaped cross section, is fixed to the vehicle body outer panel B using double-sided adhesive tape 1, as in the conventional case. In the internal space of the molding body 2, there is a transparent cover 4 molded in an inverted "C" shape from a rigid transparent material such as acrylic resin, and the open ends 4a and 4b of this transparent cover 4 are liquid-tight. It incorporates a surface emitter or electroluminescent element 6 surrounded by a reinforcing plate 5 which is fixed to the surface. As can be understood from FIG. 5, which shows an enlarged cross-section in the thickness direction, the electroluminescent element 6 made in the shape of an elongated flat plate is made of laminated transparent electrode layers housed in a transparent moisture-proof enclosure 7. 6a, light emitter layer 6b, reinforcing layer 6c,
A lead wire 8 formed of the back electrode layer 6d and connected to the transparent electrode layer 6a and the back electrode layer 6d runs from the end 7a of the moisture-proof enclosure 7 to the molding body 2.
It penetrates the bottom wall 2a of the vehicle body outer panel B and is led out into the interior of the vehicle body outer panel B. Needless to say, this electroluminescent element 6 is housed between the transparent cover 4 and the reinforcing plate 5 with the transparent electrode layer 6a side facing the transparent cover 4.

Further, in order to attach the assembly consisting of the transparent cover 4, the electroluminescent element 6, and the reinforcing plate 5, a cut groove 9 extending in the length direction is formed in the bottom wall 2a of the molding body 2. Therefore, as shown by the imaginary line in FIG.
By pushing open the bottom wall 2a, the aforementioned assembly can be loaded into the interior of the molding body 2. Of course, when the molding main body 2 is attached to the vehicle body outer panel B, the double-sided adhesive tape 1 is attached to the bottom surface of the molding main body 2, so that rainwater etc. can pass through the cut grooves 9 onto the molding main body 2. There will be no intrusion inside.

Since the embodiment has the above configuration,
As shown in FIG. 6, an alternating current voltage may be applied to the electroluminescent element 6 in response to a lighting signal from a night light switch S. That is, the control circuit C to which the output signal of the night light switch S is inputted has an inverter built into it that converts the DC power supply voltage installed in the vehicle into the AC voltage necessary for driving, and the output voltage of this inverter is The electroluminescent element 6 will be driven.

In the above embodiments, an electroluminescent element was illustrated as an example of a surface light emitter, but in the present invention, other surface light emitters may be used, and the present invention also applies to guard moles. It may also be applied to other decorative moldings without limitation.

As is clear from the above description, according to the present invention, by making the surface illuminant shine when parking at night, the light emission can be reliably recognized even from a distance, so collision accidents can be prevented. Furthermore, since the surface light emitter in the molding of the present invention is incorporated inside the rigid transparent cover, it is sufficiently protected from the pressure applied to the molding body, so that a part of the surface light emitter may be locally folded. As shown in the illustrated embodiment, the bottom wall of the molding body is fixed to the vehicle body outer panel in a liquid-tight manner using double-sided adhesive tape, so rainwater, etc. does not pass through the cut grooves. can be prevented from entering the inside of the molding body. moreover,
With the molding of the present invention, the surface light emitting element completely packed in the moisture-proof enclosure can be incorporated into the transparent cover later, so that the manufacturing process can be easily streamlined.
