Detailed Description

The present disclosure is described in further detail below with reference to the drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant content and not limiting of the present disclosure. It should be further noted that, for convenience of description, only a portion relevant to the present disclosure is shown in the drawings.

In addition, embodiments of the present disclosure and features of the embodiments may be combined with each other without conflict. The technical aspects of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Unless otherwise indicated, the exemplary implementations/embodiments shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure may be practiced. Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present disclosure.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" higher "and" side (e.g., in "sidewall") to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below" … … can encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when the terms "comprises" and/or "comprising," and variations thereof, are used in the present specification, the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof is described, but the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof is not precluded. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximation terms and not as degree terms, and as such, are used to explain the inherent deviations of measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.

Referring to fig. 1, preferably, the second pawl 6 drives the sliding pawl 8 out of sliding from the first position and simultaneously drives the first pawl 4 to rotate in a direction away from the first locking position of the locking bolt 2 based on the second feature 602, or the second pawl 6 drives the sliding pawl 8 and the first pawl 4 in sequence such that the sliding pawl 8 out of sliding from the first position and the first pawl 4 rotates in a direction away from the first locking position of the locking bolt 2.

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

an unlocking torque (which may be provided by a shackle, not shown) received by the locking 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 a first locking position, out of the locking bolt 2.

The shape of the first locking position 201 and/or the shape of the first locking surface 401 can be used to enable an unlocking torque received by the locking bolt 2 to be introduced into the first pawl 4.

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

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

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

The second operating lever may be, for example, an emergency lock lever, which may be a manually operated drive lever.

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

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 slide pawl 8 to slide out from the first position, thereby enabling the first pawl 4 to be disengaged from the first locking position 201, thereby achieving electric unlocking of the locking device 1000.

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

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 lever or the lock tongue 2 to drive the lock tongue 2 to move from the half-lock position to the full-lock position, thereby realizing the electric attraction of the locking device 1000.

According to a 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 lever (not shown) or the latch bolt 2, and the fourth operating lever can drive the latch bolt 2 or a shackle engaged with the latch bolt 2, so that the latch bolt 2 moves from the full lock position to the half lock position, and 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.

The various components of the locking device 1000 of this embodiment may be those described above, and will not be described again.

The operation of the locking device 1000 of the present disclosure is described in detail below with reference to fig. 8-13.

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

As shown in fig. 9, the second pawl 6 rotates counterclockwise upon actuation of an unlocking actuator (e.g., the first electric actuator described above), and the second pawl 6 slides the sliding pawl 8 out of between the first pawl 4 and the limiting portion 10 via the slot feature 603.

As shown in fig. 10, since the first locking position 201 of the locking bolt 2 is designed such that the locking bolt 2 can introduce an unlocking torque into the first pawl 4 via the first locking position 201, and the unlocking torque can cause the first pawl 4 to have a tendency to move in the opening direction (unlocking direction, counterclockwise direction in the drawing), the first pawl 4 will simultaneously move in the opening direction, while the second pawl 6 will, via the second feature 602, completely disengage the first locking surface 401 of the first pawl 4 from the first locking position 201 of the locking bolt 2 by pushing the first feature 402 of the first pawl 4.

As shown in fig. 11, the latch tongue 2 is moved to the fully opened position by the latch tongue spring 3, thereby fully releasing the shackle (not shown).

As shown in fig. 12, when the latch tongue 2 moves to the half-locking position under the pushing of the shackle, the second pawl 6 is rotated clockwise under the driving of the second pawl spring 7, so that the second locking surface 601 of the second pawl 6 is locked into the second locking position 202 of the latch tongue 2, thereby locking the latch tongue 2 in the half-locking position. At this point, the sliding pawl first shaft feature 802 of the sliding pawl 8 can slide within 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 lock tongue 2 continues to rotate clockwise to the full locking position, the first pawl 4 rotates clockwise under the drive of the first pawl spring 5, so that the first locking surface 401 of the first pawl 4 locks into the first locking position 201 of the lock tongue 2 to lock the lock tongue 2 in the half locking position, and meanwhile, the sliding pawl 8 wedges between the first pawl 4 and the limiting part 10 under the drive of the sliding pawl spring 9, thereby locking the first pawl 4 in the locking position, and realizing reliable locking of the lock tongue 2.

A motor vehicle lock according to one embodiment of the present disclosure includes: the locking device 1000 of any of the embodiments of the present disclosure; and a shackle that cooperates with the tongue 2 of the locking device 1000 to perform a locking function.

A motor vehicle according to one embodiment of the present disclosure includes: the motor vehicle lock of any of the embodiments of the present disclosure is disposed on a door and/or a cover of a motor vehicle.
