Benefits of technology

The present patent provides a way to make vehicle interior materials that look better and make users feel more emotionally connected. It uses a foam-injection molding process that includes an EL sheet. The foam layer also contains something to prevent the sheet from being exposed when it's not emitting light. Overall, this method creates materials that are more visually appealing and offer a better user experience.

Problems solved by technology

However, in the case of using the illumination unit 12 as described above, there is a problem that the night view visibility is deteriorated as the user is affected by a glare phenomenon.
In addition, there is a problem that the beauty of the handle unit 10 is deteriorated against expectation due to complicatedness of the illumination unit 12.

Abstract

Provided is a structure of foam-injection molding including an EL sheet. The structure includes: a base material; an electro luminescence (EL) sheet which is able to emit a light, and which is disposed on an upper side of the base material; a foam layer disposed on an upper side of the EL sheet; and a skin layer disposed on an upper side of the foam layer.

Description

BACKGROUND OF THE INVENTIONField of the Invention[0001]The present disclosure relates to a structure and a method of foam-injection molding including an EL sheet, and more particularly, to a structure and a method of foam-injection molding including an EL sheet for maximizing the soft feeling of a vehicle interior material and enhancing an interior decoration effect.Description of the Related Art[0002]Generally, a vehicle interior material is a part used for interior decoration of a vehicle, which is integrally formed as a second member such as a resin is pressed onto a first member such as a fabric to be mounted on the vehicle.[0003]Conventional vehicles are regarded as merely a kind of transportation means, and the beauty or the feel of the vehicle interior material is not seriously considered. However, at present, vehicles are considered as an article that expresses the individuality of a user beyond the role of the vehicle as a means of transportation.[0004]In this trend, the in...
