Latch assembly for opening and closing luggage room of vehicle

A latch assembly for opening and closing a luggage room of a vehicle, the latch assembly comprising:

• a base installed on an end portion of an opening and closing member configured to open and close the luggage room of the vehicle, and having a striker fixed to a vehicle body of the vehicle;
• a power conversion mechanism configured to convert a rotational force of a drive motor into at least one linear motion;
• a claw configured to grip and restrain the striker when the opening and closing member closes the luggage room;
• a pawl configured to inhibit rotation of the claw so that the claw maintains a state of having the striker restrained;
• an error lever installed to rotate with the pawl and configured to rotate so that the pawl is separated from the claw when the power conversion mechanism converts the rotational force of the drive motor into the at least one linear motion;
• and
• a link mechanism configured to rotate the claw so that the claw grips the striker, when the power conversion mechanism converts the rotational force of the drive motor into the at least one linear motion,
• wherein the power conversion mechanism comprises:
• a screw shaft configured to be rotated by the drive motor;
• and
• a holder which is screw-coupled to the screw shaft and configured to rotate the error lever while moving along an axial direction of the screw shaft,
• wherein the holder is formed with a cinching-release pin, and the cinching-release pin is configured to:
• contact the error lever to push the error lever to be spaced apart from the claw for releasing the striker, and
• push and rotate a first link of the link mechanism so that the claw reaches a full lock state, where the claw fully restrains the striker, from a half lock state, and
• wherein the error lever is formed with a claw restraint pin guide groove that accommodates a claw restraint pin, wherein when the claw restraint pin is disposed within the claw restraint pin guide groove, the claw restraint pin is disposed outside of the claw or contacts the claw to rotate the claw to grip the striker.
