Problems solved by technology

[0008] However, in this electric tailgate device, the tightening motor and the releasing motor are installed separately from each other, thus resulting in an increase in the manufacturing cost and weight of the device
In addition, due to the large number of components, the defect rate of the device increases

Abstract

A tailgate opening / closing device has a simplified tailgate opening / closing structure, reduced manufacturing cost, reduced weight, and improved quality. The device includes a release gear configured to be rotated forwards and backwards by a rotational force from a motor, a cinching gear engaged with the release gear, a linkage mechanism configured to receive force from the cinching gear to rotate toward a claw, the claw being caught by the linkage mechanism to rotate together therewith so as to be engaged with a striker, and a pawl unit configured to be caught by the claw in the state in which the claw is engaged with the striker so as to restrict rotation of the claw and configured to allow rotation of the claw in a release operation direction only when the release gear rotates in the release operation direction.

Description

technical field [0001] The present disclosure relates to a tailgate opening and closing device having a simplified tailgate opening and closing structure, reduced manufacturing cost, reduced weight, and improved quality. Background technique [0002] Generally, a sport utility vehicle (SUV) or a multi-purpose vehicle (MPV) has an opening formed in the rear thereof for a user to easily load items into the vehicle and a tailgate for opening and closing the opening. [0003] For example, a claw is mounted to a tailgate, and a striker is mounted to a vehicle body. When the tailgate is closed, the claw engages the striker so that the tailgate is locked. When the release lever is operated, the claw is disengaged from the striker, so that the tailgate is unlocked. [0004] Particularly, in the case of a power tailgate device that is locked and unlocked by an electrically driven claw and striker, a cinching motor that performs a locking operation and a release motor that performs ...
