Abstract
Provided is a soft upper trim of a vehicle door, in which an upper substrate, foam, and a transparent skin are laminated, and particularly, to a soft upper trim for switch assembly of a vehicle door, in which a switch, which is configured to preserve continuity of a transparent skin and display lock and unlock symbols on the transparent skin, is easily assembled to an upper substrate, and a method of manufacturing the same.
Claims3
A method of manufacturing a soft upper trim fora switch assembly of a vehicle door in which a molding layer and a transparent layer are formed in a state in which a light guide plate is assembled to an upper substrate, the method comprising:
- (a) injection-molding the upper substrate such that a lower recessed groove and an upper recessed groove communicate with each other, wherein a switch module is inserted into the lower recessed groove in a lower side of the upper substrate and a light guide plate engraved with a symbol is inserted into the upper recessed groove in an upper side of the upper substrate;
- (b) assembling the light guide plate in the upper recessed groove, wherein the light guide plate is assembled such that an upper surface of the light guide plate is placed at a higher level than an upper surface of the upper substrate;
- (c) forming the molding layer by injection-molding a transparent resin on upper surfaces of the upper substrate and the light guide plate in a state in which the upper substrate assembled with the light guide plate is inserted;
- and
- (d) forming the transparent layer by ejecting a transparent paint on an upper surface of the transparent resin.
A soft upper trim for switch assembly of a vehicle door, the soft upper trim comprising an upper substrate, a molding layer, and a transparent layer, which are laminated, wherein:
- an upper recessed groove and a lower recessed groove are formed in the upper substrate so as to communicate with each other, wherein a switch module is inserted into the lower recessed groove;
- a light guide plate is assembled in the upper recessed groove and has a symbol engraved in an upper side thereof;
- the molding layer includes a transparent resin which is injection-molded on upper surfaces of the upper substrate and the light guide plate;
- and
- the transparent layer includes a transparent paint which is applied on an upper surface of the transparent resin,
- wherein the transparent resin includes a thermoplastic elastomer (TPE) material;
- the transparent paint includes a urethane material;
- the upper substrate includes polypropylene (PP);
- and the light guide plate includes polycarbonate (PC), and
- wherein the light guide plate includes side plates and an upper plate, which connects upper surfaces of the side plates and has the symbol engraved therein;
- an accommodation groove, in which an upper side of the switch module is inserted and accommodated, is further formed inside a lower side of the light guide plate;
- and an upper surface of the light guide plate is placed at a higher level as an upper surface of the upper substrate.
