Abstract
A dual unlocking hood latch system allows a user to open a hood of the automobile vehicle while staying in the vehicle. The dual unlocking hood latch system includes a base fixed to a main body. The base includes a moving groove portion to guide the movement of a striker. A latch gear, which includes a plurality of locking portions, is pivotably attached to a front side of the base to retain the striker when the striker is entered through the moving groove portion to a locking position. A pawl, pivotably attached to the base, controls the movement of the latch gear by transmitting rotational motion when in contact. And a stopper portion, pivotably attached to the base, is elastically biased to move toward the pawl such that the stopper portion is pushed by the pawl to restrain pivoting movement of the latch gear.
Claims8
A dual unlocking hood latch system, comprising:
- a base comprising a moving groove portion for guiding a movement of a striker, the base attached to a main body;
- a latch gear comprising a first locking portion, a second locking portion and a third locking portion, the latch gear pivotably attached to a front side of the base for directly restraining the striker in a mounting groove portion between the first locking portion and the second locking portion when the striker is entered through the moving groove portion to a locking position and for directly restraining the striker from further unlocking when the dual unlocking hood latch system transitions from the locking position to a first unlocking position, the latch gear comprising a plurality of locking portions;
- a pawl pivotably attached to the base, the pawl comprising a single locking protrusion for directly restraining the latch gear from rotating by directly abutting against the second locking portion of the latch gear when the dual unlocking hood latch system is in the locking position and by abutting against the third locking portion of the latch gear the first unlocking position;
- and
- a stopper portion comprising a stopper protrusion and pivotably attached to the base and elastically pressured to a direction of the pawl such that the stopper portion is in constant direct contact with the pawl during both the locking position and the first unlocking position, wherein the stopper portion is pushed by the pawl to restrain the movement of the latch gear such that the pawl abuts the stopper portion when the dual unlocking hood latch system transitions from the locking position to the first unlocking position, and while the dual unlocking hood latch system transitions from the locking position to the first unlocking position, the stopper is pushed by the pawl to temporarily restrain the latch gear from rotating by causing the stopper protrusion to directly abut against the a second locking portion of the latch gear.
