DETAILED DESCRIPTION
The present disclosure is further described in detail below with reference to the accompanying drawings and implementations. It can be understood that the specific implementations described herein are only used to explain related content, but are not intended to limit the present disclosure. It should be further noted that, for ease of description, only a part related to the present disclosure is shown in the accompany drawings.
It should be noted that, on the premise of no conflict, the implementations in the present disclosure and features in the implementations may be combined with each other. Technical solutions of the present disclosure are described in detail below with reference to the accompanying drawings in conjunction with the implementations.
Unless otherwise specified, the illustrated exemplary implementations/embodiments are understood as providing exemplary features of various details of some ways in which technical concepts of the present disclosure may be implemented in practice. Therefore, unless otherwise specified, the features of 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 crosshatch and/or shade in the accompanying drawings is generally used to make a boundary between adjacent parts clear. In this case, unless otherwise specified, the presence or absence of the crosshatch or shade does not express or indicate any preference or requirement for a specific material, material property, size, proportion of a part, commonality between illustrated parts, and/or any other characteristic, attribute, property, and the like of the part. In addition, in the accompanying drawings, a size and a relative size of a part may be exaggerated for clarity and/or a purpose of description. When exemplary embodiments may be implemented differently, a specific process sequence may be performed in an order different from an order described. For example, two consecutively described processes may be performed substantially simultaneously or in an order reverse to an order described. In addition, the same reference numerals denote the same part.
When a part is referred to as being "on" or "over", "connected to", or "coupled to" another part, this part may be directly on, connected to, or coupled to the another part, or an intermediate part may exist. However, when a part is referred to as being "directly on", "directly connected to", or "directly coupled to" another part, an intermediate part does not exist. Therefore, the term "connected" may refer to physically connected, electrically connected, and the like, and an intermediate part exists or does not exist.
For a purpose of description, the present disclosure may use spatially relative terms such as "beneath...", "below...", "under...", "lower", "above...", "upper", "on...", "higher", and "side (for example, in a "sidewall")" to describe a relationship between one part and another (other) part as shown in the accompanying drawings. The spatially relative terms are intended to include different orientations of a device in use, operation, and/or manufacturing in addition to the orientations depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, a part that is described as "below" or "beneath" another part or feature is then located "above" the other part or feature. Therefore, the exemplary term "below..." may include two orientations: "above" and "below". In addition, the device may be further located (for example, the device is rotated 90 degrees or at another orientation). In this case, the spatially relative terms used herein are explained accordingly.
The terms used herein are for a purpose of describing specific embodiments and are not intended to put a limit. As used herein, unless otherwise clearly specified in the context, singular forms "one" ("a" and "an") and "said (the)" are intended to include plural forms as well. In addition, when used in this specification, the terms "comprise" and/or "include" and variations thereof indicate presence of the described features, entireties, steps, operations, parts, assemblies and/or a combination thereof, but does not exclude presence or addition of one or more other features, entireties, steps, operations, parts, assemblies and/or a combination thereof. It should be further noted that, as used herein, the terms "substantially" and "about", and other similar terms are used as approximate terms rather than degree terms, and therefore, they are used to explain an inherent deviation that is of a measured value, a calculated value, and/or a provided value and that will be recognized by those of ordinary skill in the art.

400 separates from the limit block 600, as shown in FIG. 11. Then, the second pawl 300 continues to drive the
control rod
control member
400 to rotate clockwise, and the drive part 403 (which may be in a form of a drive surface) pushes, through the first drive surface 203, the first pawl 200 to rotate clockwise, so that the first pawl 200 is separated from the first locking surface 101, and the lock tongue 100 is unlocked, as shown in FIG. 12. After that, the lock tongue 100 rotates clockwise to a full open position, as shown in FIG. 13. After the second drive surface 303 of the second pawl 300 is released, the first pawl 200 and the second pawl 300 stop against the lock tongue 100 under the action of the elastic part 500 (which functions as a return spring), and the
control rod
control member
400 stops against the limit block 600 under the action of the elastic part 500, so that the lock device implements unlocking. As shown in FIG. 14 and FIG. 15, FIG. 14 and FIG. 15 show an unlocked state of the lock device from different perspectives.
A locking process of the lock device of the present disclosure is described in detail below with reference to FIG. 16 to FIG. 21.

[[at ]]
in
the full open position and the first pawl 200 and the second pawl 300 stopping against the lock tongue 100.
In an event that the lock tongue 100 is pushed to rotate to the secondary locking position (the second locking position), the second pawl 300 rotates clockwise (in FIG. 16) to enter the secondary locking position, so that the lock device 1000 implements locking at the secondary locking position, as shown in FIG. 18. Then, in an event that the lock tongue 100 continues to rotate to the primary locking position (the first locking position), the first pawl 200 enters the primary locking position to lock the lock tongue 100
[[at ]]
in
the primary locking position, and meanwhile, the
control rod
control member
400 is inserted between the first pawl 200 and the limit block 600 under the action of a
control rod
control member
spring (the elastic part 500), so that the first pawl 200 is limited
[[at ]]
in
the primary locking position, to improve reliability of the lock device, as shown in FIG. 19 to FIG. 21.
According to the lock device of the present disclosure, for example, locking reliability of the first pawl and the lock tongue is improved by designing the
control rod
control member
, the elastic part (the
control rod
control member
spring), and the limit block on the outer side of the first pawl, and the first pawl is released through a connection between the second pawl and the
control rod
control member
