Abstract

A power latch apparatus is provided. The apparatus includes a rotary cam that is rotatably connected to a cam shaft and includes a cam groove, a transmission rod that is slidably connected to the camgroove and pressed and moved as the rotary cam rotates, and a claw to which the transmission rod is rotatably connected and that is pressed by the movement of the transmission rod to rotate about a claw shaft. The claw includes a claw recess that limits a striker movement that fits into the claw recess during a cinching operation, and a pawl to prevent the claw from rotating in a release directionin which a release operation of separating the striker from the claw recess is performed, or rotates about a pawl shaft while being pressed by the rotary cam, the pawl to allow the claw to rotate inthe release direction.

Description

[0001] Cross-references to related applications [0002] This application claims priority from Korean Patent Application No. 10-2018-0131650 filed on October 31, 2018, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to a powered latch device for use in a vehicle power system, and more particularly, to a powered latch device that utilizes a single drive device to perform a release operation and a tightening operation. Background technique [0004] Latch devices used in powertrain systems of vehicles (eg, doors, hoods, tailgates, trunks, etc.) include release motors and retraction motors to automatically perform opening (release) and closing (tighten) operations. The latch device performs these operations separately in such a way that for the release operation the release motor is used and the take-up motor is stopped, and for the take-up operation the take-up motor is used and the release motor is stop...
