Abstract
A vehicle latch includes a catch which restricts or releases a striker disposed in a vehicle body, a pawl which comes into contact with one side of the catch to restrict rotation of the catch, a motor which transmits power to a link part, a worm gear engaged with the motor and rotated by operation of the motor, a cinching gear that is engaged with the worm gear, rotates in a direction opposite to that of the worm gear, and includes a protrusion formed to protrude from a front surface, and the link part of which one side is in contact with the protrusion and the other side is in contact with the catch to allow the catch to be rotated by rotation of the protrusion.
Claims20
A vehicle latch comprising:
- a catch which restricts or releases a striker disposed in a vehicle body;
- a pawl which comes into contact with one side of the catch to restrict rotation of the catch;
- a motor which transmits power to a link part;
- a worm gear engaged with the motor and rotated by operation of the motor;
- and
- a cinching gear that is engaged with the worm gear, rotates in a direction opposite to that of the worm gear, and includes a protrusion formed to protrude from a front surface of the cinching gear;
- wherein the link part includes a first side that is in contact with the protrusion and another side that is in contact with the catch to allow the catch to be rotated by rotation of the protrusion;
- wherein, in a process in which the catch is rotated such that a locked state is changed to an open state, the link part is contact-supported by one side of the catch, the catch is rotated by movement of the link part, and tailgate opening noise generation is suppressed;
- and
- wherein the worm gear includes a release part which is formed such that a central portion of the worm gear protrudes in a forward direction, is disposed to radially protrude from a center of the worm gear, and is formed to protrude gradually away from the center of the worm gear, and of which an outer circumference comes into contact with the pawl.

A vehicle latch comprising:
- a catch configured to restrict or release a striker disposed in a vehicle body;
- a pawl configured to come into contact with one side of the catch to restrict rotation of the catch;
- a link part;
- a motor configured to transmit power to the link part;
- a worm gear engaged with the motor so as to be able to be rotated by operation of the motor;
- and
- a cinching gear that is engaged with the worm gear and is configured to rotate in a direction opposite to that of the worm gear, the cinching gear including a protrusion formed to protrude from a front surface of the cinching gear;
- wherein the link part includes one side that is in contact with the protrusion and another side that is in contact with the catch to allow the catch to be rotated by rotation of the protrusion;
- wherein, in a process in which the catch is rotated such that a locked state is changed to an open state, the link part is contact-supported by one side of the catch, the catch is rotated by movement of the link part, and tailgate opening noise generation is suppressed;
- and
- wherein the worm gear includes a release part which is formed such that a central portion of the worm gear protrudes in a forward direction, is disposed to radially protrude from a center of the worm gear, and is formed to protrude gradually away from the center of the worm gear.
