Soft upper trim for switch assembly of vehicle door and method of manufacturing the same
Provided is a soft upper trim of a vehicle door, in which an upper substrate, a 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.
1. A soft upper trim for switch assembly of a vehicle door, the soft upper trim comprising an upper substrate, a foam, and a transparent skin, which are laminated, wherein:
the upper substrate has a through-hole vertically formed therein, in which a switch module is inserted;
an upper surface of the upper substrate is formed as an inclined surface which is gradually inclined upward toward the through-hole;
the foam includes an inclined foam pressed on the inclined surface and a horizontal foam disposed in the through-hole and having a hole vertically formed therein; and
a light guide plate is inserted into the through-hole such that a symbol is disposed at a position corresponding to the hole.
2. The soft upper trim according to claim 1 , wherein the light guide plate includes side plates, an upper plate which connects upper surfaces of the side plates and has the symbol engraved therein, and flanges which are formed at lower sides of the side plates and are caught on a latch stepped portion of the first through-hole, wherein an accommodation groove, in which a upper side of the switch module is inserted and accommodated, is formed inside a lower side of the light guide plate.
3. A soft upper trim for switch assembly of a vehicle door, the soft upper trim comprising an upper substrate, a foam, and a transparent skin, which are laminated, wherein:
the upper substrate has a first through-hole vertically formed therein, in which a switch module is disposed;
an upper surface of the upper substrate is formed as an inclined surface which is gradually inclined upward toward the through-hole;
the foam includes an inclined foam pressed on the inclined surface and a horizontal foam disposed in the through-hole;
a foam recessed groove at least further recessed upward compared to the foam on the inclined surface of the upper substrate formed in a lower surface of the horizontal foam; and
a light guide plate having an upper surface engraved with a symbol inserted into the through-hole and the foam recessed groove.
4. The soft upper trim according to claim 3 , wherein the light guide plate includes side plates, an upper plate which connects upper surfaces of the side plates and has the symbol engraved therein, and flanges which are formed at lower sides of the side plates and are caught on a latch stepped portion of the first through-hole, wherein an accommodation groove, in which a upper side of the switch module is inserted and accommodated, is formed inside a lower side of the light guide plate.
