According to a preferred embodiment of the present disclosure, the first pawl 4 and the latch tongue 2 of the locking device 1000 of the present disclosure are configured as:

an unlocking torque (which may be provided by a catch, not shown) received by the bolt 2 can be introduced into the first pawl 4, which unlocking torque can cause the first pawl 4 to have a tendency to rotate towards the first locking position out of the bolt 2.

The shape of the first locking position 201 and/or the shape of the first locking surface 401 can be designed such that an unlocking torque received by the locking tongue 2 can be introduced into the first pawl 4.

According to a preferred embodiment of the present disclosure, the second locking position 202 of the latch bolt 2 of the locking device 1000 of the present disclosure is designed such that the latch bolt 2 can introduce an unlocking torque to the second pawl 6 through the second locking position 202.

The unlocking torque described above preferably passes through the center of rotation of the second pawl 6, or causes the second pawl 6 to have a tendency to move in the locking direction (clockwise in fig. 1).

In some embodiments of the present disclosure, the first pawl 4 can be driven by the second operating lever to rotate toward the first locking position 201 of the latch bolt 2 or driven by the second operating lever to disengage from the first locking position 201 of the latch bolt 2.

The second operating lever may be, for example, an emergency locking lever, which may be a drive lever based on manual operation.

In some embodiments of the present disclosure, the locking device 1000 of the present disclosure further comprises:

a first electric actuator (not shown) including at least a motor;

the driving force of the motor of the first electric actuator can be transmitted to the first operating lever or the second pawl 6 described above, so that the first operating lever or the second pawl 6 drives the sliding pawl 8 to slide out from the first position, and further the first pawl 4 can be disengaged from the first locking position 201, thereby realizing the electric unlocking of the locking device 1000.

In further embodiments of the present disclosure, the locking device 1000 of the present disclosure further comprises:

a second electric actuator (not shown) including at least a motor;

the driving force of the motor of the second electric actuator can be transmitted to the third operating rod or the bolt 2 to drive the bolt 2 to move from the half-locking position to the full-locking position, so that the electric suction of the locking device 1000 is realized.

According to the preferred embodiment of the present disclosure, the driving force of the motor of the second electric actuator can also be transmitted to a fourth operating rod (not shown) or the latch 2, and the fourth operating rod can drive the latch 2 or a lock catch matched with the latch 2, so that the latch 2 moves from the full-lock position to the half-lock position, and thus the electric ice breaking of the locking device 1000 is realized.

According to a preferred embodiment of the present disclosure, the locking device 1000 includes:

a pawl holding portion 11, the pawl holding portion 11 including a first shaft portion 1101 and a second shaft portion 1102, the first pawl 4 being rotatable about the first shaft portion 1101, the second pawl 6 being rotatable about the second shaft portion 1102;

wherein the axis of the first shaft portion 1101 is parallel to but not collinear with the axis of the second shaft portion 1102.

Each component of the locking device 1000 of this embodiment may be the above-described component, and is not described again.

The operation of the locking device 1000 of the present disclosure will be described in detail with reference to fig. 8 to 13.

As shown in fig. 8, the locking device 1000 is in the full lock state, and the latch bolt 2 is in the full lock position.

As shown in fig. 9, the second pawl 6 is driven by an unlocking actuator (e.g., the first electric actuator described above) to rotate counterclockwise, and the second pawl 6 drives the sliding pawl 8 to slide out from between the first pawl 4 and the limiting portion 10 through the slot feature 603.

As shown in fig. 10, since the first locking position 201 of the locking bolt 2 is designed to enable the locking bolt 2 to introduce an unlocking torque into the first pawl 4 through the first locking position 201, and the unlocking torque enables the first pawl 4 to have a tendency to move toward an opening direction (unlocking direction, counterclockwise in the drawing), the first pawl 4 will move toward the opening direction at the same time, and the second pawl 6 enables the first locking surface 401 of the first pawl 4 to be completely disengaged from the first locking position 201 of the locking bolt 2 by pushing the first feature 402 of the first pawl 4 through the second feature 602, so as to unlock the locking bolt 2.

As shown in fig. 11, the latch 2 is moved toward the fully open position by the latch spring 3, thereby completely releasing the latch (not shown).

As shown in fig. 12, when the latch bolt 2 moves to the half-locked position under the pushing of the lock catch, the second pawl 6 is driven by the second pawl spring 7 to rotate clockwise, so that the second locking surface 601 of the second pawl 6 is locked into the second locking position 202 of the latch bolt 2, thereby locking the latch bolt 2 at the half-locked position. At this point, the sliding pawl first shaft feature 802 of the sliding pawl 8 can slide in the slot feature 603 of the second pawl 6 without affecting the locking action of the second pawl 6.

As shown in fig. 13, as the latch bolt 2 continues to rotate clockwise to the full-locking position, the first pawl 4 rotates clockwise under the driving of the first pawl spring 5, so that the first locking surface 401 of the first pawl 4 is locked into the first locking position 201 of the latch bolt 2, and the latch bolt 2 is locked at the half-locking position, and meanwhile, the sliding pawl 8 is wedged between the first pawl 4 and the limiting part 10 under the driving of the sliding pawl spring 9, so that the first pawl 4 is locked at the locking position, and the reliable locking of the latch bolt 2 is realized.
