It should be further noted that, for the convenience of description, only the portions relevant to the present disclosure are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. Technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Unless otherwise indicated, the illustrated exemplary embodiments/examples 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. Accordingly, unless otherwise indicated, features of the various embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concept of the present disclosure.

The use of cross-hatching and/or shading in the drawings is generally used to clarify the boundaries between adjacent components. As such, unless otherwise noted, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, size, proportion, commonality between the illustrated components and/or any other characteristic, attribute, property, etc., of a component. Further, in the drawings, the size and relative sizes of components may be exaggerated for clarity and/or descriptive purposes. While example embodiments may be practiced differently, the specific process sequence may be performed in a different order than that described. For example, two processes described consecutively may be performed substantially simultaneously or in reverse order to that described. In addition, like reference numerals denote like parts.

When an element is referred to as being "on" or "on," "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 purposes of this disclosure, the term "connected" may refer to physically, electrically, etc., and may or may not have intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "below … …," below … …, "" below … …, "" below, "" above … …, "" above, "" … …, "" higher, "and" side (e.g., as in "side wall") to describe one component's relationship to another (other) component as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below … …" can encompass both an orientation of "above" and "below". Further, the devices 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 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.

The unlocking process of the locking device of the motor vehicle lock 1000 of the present disclosure is explained in detail below with reference to fig. 16.

Initially, the second pawl 900 is locked in the primary locking position (first locking position) by the first pawl 200. When the second driving surface of the second pawl 900 is shifted by the unlocking mechanism (not shown), the second pawl drives the blocking lever 100 to rotate counterclockwise, so that the blocking lever 100 is disengaged from the stopper 750. As the second pawl 900 continues to rotate the blocking lever clockwise, the driving portion (which may be in the form of a driving surface) pushes the first pawl to rotate clockwise via the first driving surface, so that the first pawl is disengaged from the first locking surface 301, and the second pawl 900 is unlocked. The second pawl 900 is then rotated clockwise to the fully open position. When the second driving surface of the second pawl 900 is released, the first pawl 200 and the second pawl 900 stop on the second pawl 900 under the action of the second elastic part 650 (acting as a return spring), and the locking rod 100 stops on the limit block 750 under the action of the second elastic part 650, so that the unlocking of the motor vehicle lock is realized.

The locking process of the motor vehicle lock of the present disclosure is explained in detail below with reference to fig. 16.

With the locking mechanism in the fully open position, the first pawl 200 and the second pawl 900 rest on the second pawl 900.

When the second pawl 900 is pushed to rotate to the secondary lock position (second lock position) toward the lock position, the second pawl 900 rotates clockwise to enter the secondary lock position, and the motor vehicle lock 1000 is locked at the secondary lock position. When the second pawl 900 continues to rotate to reach the main locking position (first locking position), the first pawl 200 enters the main locking position, the second pawl 900 is locked at the main locking position, and meanwhile, the locking rod 100 is inserted between the first pawl 200 and the limiting block 750 under the action of a locking rod spring (elastic part), so that the first pawl 200 is limited at the main locking position, and the reliability of the motor vehicle lock is improved.

In the motor vehicle lock 1000 of the present disclosure, as shown in fig. 16, for example, by designing the dead lock lever 100, the second elastic portion 650 (dead lock lever spring), and the stopper 750 on the outer side of the first pawl 200, the reliability of locking the first pawl 200 and the second pawl 900 is improved, and by connecting the second pawl 900 and the dead lock lever 100, the release of the first pawl 200 is realized, and the unlocking force is reduced.

Fig. 17 shows an ice breaking device according to yet another embodiment of the present disclosure, which includes a first ice breaking pull rod 400 and a second ice breaking pull rod 410, wherein the first ice breaking pull rod 400 pushes the second ice breaking pull rod 410 to rotate, the second ice breaking pull rod pushes a lock catch 420 to move, and the lock catch 420 pushes a lock tongue to move away from a full lock position to a pre-lock position, so as to achieve an ice breaking function.
