Emblem-unified trunk opening and closing device

An emblem-unified trunk opening and closing device, comprising:

• a housing including an outer case and an inner case, wherein the outer case is attached to a stationary member and includes a guide hole and the inner case includes a guide passage;
• a knob attached to the outer case of the housing, wherein the knob includes an emblem configured to be movable through the guide hole of the outer case;
• a connector provided in the guide passage of the inner case and to which a terminal electrically contacting an outer electric source is set;
• a printed circuit board (“PCB”) disposed inside the guide passage of the inner case and configured to electrically contact the terminal;
• and
• a contact unit arranged in the inner case, the contact unit being selectively in contact with the PCB by actuation force of the emblem so as to apply an electric current to the terminal of the connector;
• wherein the contact unit comprises:
• an upper guide slidably coupled to the emblem;
• an elastic member, a lower portion of which being coupled to an upper portion of the connector and an upper portion of which being elastically engaged with the upper guide;
• a lower guide coupled to the elastic member via an upper portion thereof;
• and
• a switch including an electricity applying portion being in contact with a lower portion of the lower guide to be elastically pushed by the lower guide to contact the printed circuit board;
• wherein the upper guide and the lower guide are reciprocated in the inner case by external force applied to the upper guide and elastic force of the elastic member;
• and
• wherein the lower portion of the lower guide has a cone shape, and the electricity applying portion of the switch is co-axially disposed with the cone shaped lower portion of the lower guide to allow pushing force to be concentrated onto the electivity applying portion.
