FIG. 5 is a shade diagram illustrating the state of the shaded line 4 appearing on the surface of the vehicle body 1. FIG. 5 is a view of the vehicle body 1 in which the fusing portion 3 is formed when the reflecting tool is fixed to the vehicle body 1 and then emits light. Each shaded diagram illustrating the state of the shaded line 4 appearing on the surface is shown.

As shown in the drawings, the reflection tool for the restoration of the vehicle body depression according to the present invention, the main body portion (R) is built-in electro-luminescent lamp (EL lamp) of the thin film type, and It consists of a close fitting fixture 40 for attaching and detaching the main body portion (R) at any position on the surface of the vehicle body (1).

The main body part R may apply power to the substrate 10 having a predetermined thickness and to the outside from each of the aluminum electrodes 24 and 25 deposited on and in contact with the substrate 10. And a thin film type electroluminescent lamp 20 in which the wire 26 is drawn out, and is disposed on the front surface of the electroluminescent lamp 20 to be closely fixed to the substrate 10 in the form of a laminate and extend in the longitudinal direction on the front surface thereof. A plurality of shading tape lines 31 are formed at predetermined intervals, and are formed of a transparent plate 30 for selectively transmitting the light emitted from the electroluminescent lamp 20.

Here, electroluminescence (EL) refers to a phenomenon in which light is emitted when a strong electric field is applied to a solid. The cause of light emission is that free electrons accelerated by an electric field exist in a light emitting material. This is because an electron of a specific impurity (active agent), which is a light emitting center, is excited and emits energy when it returns to the original state. The use of such a light emitting principle is an EL element, and is used for a display such as a computer screen, an optical amplifier, and the like, and other researches on the application in the television field have been conducted.

The EL element is a light emitting body using an electroluminescence principle, and is made by attaching electrodes to both surfaces of a plate-shaped light emitting layer (fluorescent layer). The light emitting layer is a solidified light emitting material such as powdered zinc sulfide (ZnS), and has a plastic type and a ceramic type. One of the electrodes may be a metal, but the other uses a transparent electrode to emit light to the outside.

The EL lamp 20 applied to the present invention is formed by forming a thin film of about 10 μm by mixing the fluorescent layer 21 with a dielectric and placing it between a transparent electrode and a capacitor. The EL lamp 20 emits fluorescent light when an AC voltage is applied. .

That is, the electroluminescent lamp 20 applied to the present invention is formed by depositing on the back surface of the fluorescent layer 21 and the fluorescent layer 21 coated with a special phosphor of zinc sulfide-based insulator 23 A pair of anodized aluminum electrodes 24 and 25 with a gap between them and drawn out from each of the aluminum electrodes 24 and 25 so that a voltage can be applied between the aluminum electrodes 24 and 25. The transparent protective film 22 formed in close contact with the entire surface of the fluorescent layer 21 to allow the electric wire 26 and the light emitted from the fluorescent layer 21 to pass through and to protect the fluorescent layer 21. It is composed of.

On the other hand, the substrate 10 is made of a semi-transparent material so that the light of the electroluminescent lamp 20 can be reflected to the front side without scattering, it can be made of glass or acrylic plate.

In addition, the shading taping line 31 formed on the transparent plate 30 is formed by attaching a detachable adhesive tape. FIGS. 2 and 3 show the shading taping line 31 maintaining a line width of a predetermined width. It is arranged at equal intervals.

In addition, the coupling structure between the substrate 10 and the transparent plate 30 adopts a method of fastening with a fastening screw 32 after forming a hole at each corresponding position. However, in addition to the screw fastening method, it is also possible to bond using an adhesive, and any other bonding method may be used.

On the other hand, the tight fixture 40 is a flexible wire that can be bent freely to be installed in a direction that is easy to work on the surface of the vehicle body 1, etc. to hold the main body portion (R) and to observe the surface curvature A gooseneck 41 is provided, and the close fixture 40 is coupled to an end of the flexible wire 41 so as to be fixed to the surface of the vehicle body 1.

In the support of the main body portion R of the present invention, the main body portion R is reduced in weight, so that only one fastening fixture 40 including the flexible wire 41 is sufficient. Therefore, since the operator can be adjusted to various angles by bending only one flexible wire 41 in any desired direction, work convenience can be significantly improved.

Here, although the various embodiments are possible as the close fixture 40, it is preferable to apply a permanent magnet or adsorption plate, etc. because it is a simple structure.

A method of determining the degree of curvature of the surface of the vehicle body 1 by the shaded line 4 which appears when the reflective tool of the present invention having the structure as described above is applied will be described with reference to FIGS. 4 and 5. Is as follows.

As mentioned above, FIG. 4 shows the state of the shaded line 4 appearing on the surface of the vehicle body 1 in which the depression 2 is formed when the reflective tool is fixed to the vehicle body 1 and then emits light. That is, since the shape of the shaded line 4 is projected convexly deformed upward and downward at the position according to the change in the surface curvature of the depression 2 position, the sheet metal can be easily beaten by tapping it from the inside of the vehicle body 1. Restoration can be done.

On the contrary, FIG. 5 shows the state of the shaded line 4 appearing on the surface of the vehicle body 1 in which the fusing portion 3 is formed when the reflective tool is fixed to the vehicle body 1 and then emits light. That is, in this case, the shape of the shaded line 4 is concave and deformed upwards and downwards at the position according to the change in the surface curvature at the position of the fusion part 3, so that this part is knocked out from the outside of the vehicle body 1. If you unfold it, you can easily restore the sheet metal.

Meanwhile, FIGS. 6 and 7 illustrate a structure of a transparent plate 30 according to another embodiment applied to a reflective tool for restoring and repairing a vehicle body recess of the present invention. FIG. 6 is a front view of the transparent plate 30. FIG. 7 shows shades appearing on the surface of the vehicle body 1 in which the recess 2 and the protrusion 3 are formed when the reflective tool to which the transparent plate 30 of FIG. 6 is fixed to the vehicle body 1 and then emits light. Each shaded diagram shows the state of a line.

As shown in the figure, the transparent plate 30 according to another embodiment of the present invention, even if the observation angle of the operator makes a small acute angle from the surface of the vehicle body 1 or the like, the shadow is projected on the surface In order to easily measure the line 5, the thickness of each line is formed differently, and each shaping taping line 33 having a differential width has a structure arranged at equal intervals.

The present invention illustrates a structure in which the line thickness of the shading taping line 33 is gradually tapered downward, and the change of the shading line 5 according to the surface shape of the depression 2 and the fusion unit 3 is previously described. As described.

The present invention can be applied to the sheet metal work as well as the body of the door, bonnet, and the like will be more useful.

As described above, the reflective tool for restoring and repairing the body recessed part of the present invention is light and installed by accommodating a very thin sheet-type electroluminescent lamp inside to form a thin-film lightweight type structure having an integrated lighting device. It is very easy to use and economical as it has semi-permanent life compared to previous separate lighting devices that use fluorescent lamps with short lifespan. The shading tape line formed on the front face clearly shows the change in the shade line projected on the surface of the vehicle body, so that it is possible to quickly and accurately determine whether the surface is warped. By forming the shaping tape line on the transparent plate on the front face using adhesive tape, The gaps and widths can be freely shaped for easy operator identification There are various advantages that can be arranged.

In particular, the reflection tool for restoring and repairing the vehicle body recessed part of the present invention may be provided with only one fastening tool including a flexible wire, since the body part itself is light in weight in supporting the main body part. Since various angles can be adjusted simply by bending one flexible wire freely, the convenience of work can be remarkably improved.
