[0061] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for ease of description, only parts related to the present disclosure are shown in the drawings.

[0062] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0063] Unless otherwise specified, the exemplary embodiments / Examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various embodiments / Examples can be additionally combined, separated, interchanged, and / or rearranged.

[0064] In the drawings, cross-hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement for the specific material, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences may be performed in an order different from that described. For example, two consecutively described processes may be performed substantially simultaneously or in an order opposite to that described. Further, the same reference numerals denote the same components.

[0065] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there may be an intermediate component. However, when the component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there is no intermediate component. For this reason, the term "connected" can refer to a physical connection, an electrical connection, etc., and may or may not have an intermediate component.

[0066] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the figures. In addition to the orientation depicted in the figures, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the figures is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both "above" and "below" orientations. Further, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0067] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. Additionally, when the terms "comprises" and / or "comprising" and their variations are used in this specification, it is stated that the stated features, integers, steps, operations, components, assemblies, and / or groups thereof are present, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, and thus are used to account for the inherent deviations of measured, calculated, and / or provided values that would be recognized by a person of ordinary skill in the art.

[0120] Preferably, the vehicle lock 1000 is at least partially made of a metal material.

[0121] According to another aspect of the present disclosure, there is also provided a vehicle, including a hood and / or a door, and the hood and / or the door are provided with the above vehicle lock 1000.

[0122] The following refers to Figure 16 to describe in detail the unlocking process of the locking device of the vehicle lock 1000 of the present disclosure.

[0123] Initially, the second pawl 900 is locked by the first pawl 200 in the main locking position (the first locking position). When the second driving surface of the second pawl 900 is toggled by an unlocking mechanism (not shown), the second pawl drives the locking rod 100 to rotate counterclockwise, so that the locking rod 100 disengages from the limit block 750. Subsequently, the second pawl 900 continues to drive the locking rod to rotate clockwise, and the driving portion (which can be in the form of a driving surface) pushes the first pawl to rotate clockwise through the first driving surface, so that the first pawl disengages from the first locking surface 301, thereby unlocking the second pawl 900. Subsequently, the second pawl 900 rotates 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 rest on the second pawl 900 under the action of the second elastic portion 650 (acting as a return spring), and the locking rod 100 rests on the limit block 750 under the action of the second elastic portion 650, thereby achieving the unlocking of the vehicle lock.

[0124] The following refers to Figure 16 to describe in detail the locking process of the vehicle lock of the present disclosure.

[0125] When the locking device is in the fully open state, the first pawl 200 and the second pawl 900 rest on the second pawl 900.

[0126] When the second pawl 900 is pushed to rotate to the sub-locking position (the second locking position) towards the locking position, the second pawl 900 rotates clockwise and enters the sub-locking position, realizing the locking of the vehicle lock 1000 at the sub-locking position. Subsequently, when the second pawl 900 continues to rotate to reach the main locking position (the first locking position), the first pawl 200 enters the main locking position and locks the second pawl 900 at the main locking position. At the same time, under the action of the locking rod spring (elastic part), the locking rod 100 is inserted between the first pawl 200 and the limit block 750 to limit the first pawl 200 at the main locking position, so as to improve the reliability of the vehicle lock.

[0127] The vehicle lock 1000 of the present disclosure, for example Figure 16 As shown, by designing the locking rod 100, the second elastic part 650 (locking rod spring) and the limit block 750 on the outer side of the first pawl 200, the reliability of the locking between the first pawl 200 and the second pawl 900 is improved. Through the connection between the second pawl 900 and the locking rod 100, the release of the first pawl 200 is realized and the unlocking force is reduced.

[0128] The ice-breaking device of another embodiment of the present disclosure is as Figure 17 shown, which includes a first ice-breaking pull rod 400 and a second ice-breaking pull rod 410. The first ice-breaking pull rod 400 pushes the second ice-breaking pull rod 410 to rotate, and the second ice-breaking pull rod pushes the lock catch 420 to move. The lock catch 420 pushes the lock tongue to move from the fully locked position to the pre-locking position, realizing the ice-breaking function.
