[0054] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0055] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0057] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0058] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0059] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, 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 drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0060] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, 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 rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0061] Figure 1 This is a schematic diagram of the front cover lock according to one embodiment of the present disclosure. Figure 2 This is a partial structural diagram of the front cover lock according to one embodiment of the present disclosure. Figure 3 This is a schematic diagram of the structure of an electrically unlocking assembly 600 for a front cover lock according to one embodiment of the present disclosure. Figure 4 This is a schematic diagram of a front cover lock according to one embodiment of the present disclosure.

[0062] The hood lock disclosed herein can be used to lock or release the hood of a vehicle, wherein the hood can be locked or released by one or two hood locks. Moreover, the hood lock of this disclosure has a double-pull opening function, that is, when the hood lock is opened for the first time, it can only be opened to a half-locked state, and when the hood lock is opened for the second time, it can be in an unlocked state.

[0063] Specifically, the front cover lock disclosed herein may include a lock body 100, a bolt component 200, a pawl component 300, an unlocking lever component 400, and a stop component 500, etc.

[0064] The lock body 100 disclosed herein can be fixed to the vehicle body, thereby realizing the installation of the hood lock. Accordingly, a latch can be provided on the hood of the vehicle; when the hood lock latch is tightened, the hood lock is locked. When the hood lock releases the latch, the hood lock is unlocked.

[0065] The latch component 200 is rotatably disposed on the lock body 100 and has a first axis of rotation. Positionally, the latch component 200 has a first locked position, a second locked position, and an unlocked position; Figure 4As shown in the direction, when the latch component 200 rotates clockwise, it can rotate from the first locked position to the second locked position. Correspondingly, when the latch component 200 rotates further clockwise, it can rotate from the second locked position to the unlocked position.

[0066] Conversely, during operation, when the latch component 200 rotates counterclockwise, it can move from the unlocked position to the second locked position; when the latch component 200 rotates further counterclockwise, it can move from the second locked position to the first locked position.

[0067] The front cover lock disclosed herein may include a latch return spring 210, which provides a return force to the latch component 200, causing the latch component 200 to tend to move toward the unlocked position. That is, when the latch component 200 is released, under the action of the return force of the latch return spring 210, the latch component 200 will rotate clockwise.

[0068] Structurally speaking, such as Figure 4 As shown, the latch component 200 has a first rotation axis, wherein the latch component 200 includes a first locking feature 201, a second locking feature 202 and an opening 203, and the first locking feature 201 and the second locking feature 202 are located on the same side of the opening 203.

[0069] The pawl component 300 has a second axis of rotation and is used to limit the position of the latch component 200. When the pawl component 300 engages with the first locking feature 201, the latch component 200 is in a first locked position, at which time the front cover lock is in a fully locked state. When the pawl component 300 engages with the second locking feature 202, the latch component 200 is in a second locked position, at which time the front cover lock is in a partially locked state.

[0070] The unlocking lever component 400 is driven to rotate, wherein, when the unlocking lever component 400 rotates, it can drive the pawl component 300 to rotate in a direction away from the latch component 200; in other words, when the front cover lock of this disclosure is manually or electrically unlocked, the unlocking lever component 400 can be subjected to external force and rotated, to Figure 4 In the direction shown, the unlocking lever component 400 will rotate clockwise, thereby causing the pawl component 300 to rotate clockwise and move from the first pawl position to the second pawl position.

[0071] In other words, the pawl component 300 includes a first pawl position and a second pawl position. When the pawl component 300 is in the first pawl position, the pawl component 300 can cooperate with the first locking feature 201 or the second locking feature 202 of the latch component 200. When the pawl component 300 is in the second pawl position, the pawl component 300 disengages from the latch component 200.

[0072] In a preferred embodiment, the rotation axis of the unlocking lever component 400 coincides with the second rotation axis of the pawl component 300, thereby making the structure of the front cover lock of this disclosure as simple and compact as possible, and correspondingly, the front cover lock is less prone to failure.

[0073] In this disclosure, the stop member 500 has a third rotation axis, wherein when the unlocking lever member 400 rotates, the stop member 500 can be driven to rotate toward the direction of approaching the latch member 200, and the stop member 500 can cooperate with the first locking feature 201 of the latch member 200 to restrict the latch member 200 to a position between the first locking position and the second locking position.

[0074] Specifically, when the unlocking lever component 400 drives the pawl component 300 to move from the first pawl position to the second pawl position, it simultaneously drives the stop component 500 from the second stop position to the first stop position. When the stop component 500 is in the first stop position, it can cooperate with the first locking feature 201 of the latch component 200. When the stop component 500 is in the second stop position, it disengages from the latch component 200.

[0075] Taking the front cover lock in the fully locked state as an example, when the unlocking lever component 400 rotates clockwise, the pawl component 300 also moves clockwise in sync. At the same time, the stop component 500 will move counterclockwise and move from the second stop position to the first stop position. At this time, since the latch component 200 is released, the latch component 200 will rotate clockwise and leave the first locking position.

[0076] However, before the locking tongue component 200 reaches the second locking position, the locking tongue component 200 will be restricted in position by the stop component 500, preventing the locking tongue component 200 from rotating further. At this time, the locking tongue component 200 will remain in a position between the first locking position and the second locking position.

[0077] When the external force applied to the unlocking lever component 400 disappears, that is, after the first opening of the front cover lock is completed, the stop component 500 will move from the first stop position to the second stop position; and release the latch component 200, at which time the latch component 200 will continue to rotate clockwise.

[0078] During the clockwise rotation of the stop component 500 and its movement from the first stop position to the second stop position, the unlocking lever component 400 and the pawl component 300 will rotate counterclockwise, causing the pawl component 300 to be located within the clockwise rotational motion envelope of the latch component 200. At this time, the second locking feature 202 of the latch component 200 will cooperate with the pawl component 300, and the pawl component 300 will restrict the latch component 200 to the second locking position. In this second locking position, the latch cannot disengage from the opening 203 of the latch component 200. At this time, the front cover lock needs to be opened a second time to unlock the front cover lock.

[0079] Similar to the first time the front cover lock is opened, when the front cover lock is opened for the second time, the unlocking lever component 400 is driven and rotates clockwise, the pawl component 300 also moves clockwise in sync, and at the same time, the stop component 500 will move counterclockwise and move from the second stop position to the first stop position. At this time, since the latch component 200 is released, the latch component 200 will rotate clockwise and leave the second locking position.

[0080] At this point, the latch component 200 can rotate directly to the unlocked position without engaging with the stop component 500 again (e.g., Figure 4 (as shown in the diagram). That is to say, during the second opening of the front cover lock, regardless of the position of the stop component 500, the latch component 200 can move to the unlocked position.

[0081] In the opposite manner of operation, when the front cover lock of this disclosure is locked, the latch component 200 can rotate counterclockwise under the push of the latch, and can rotate from the unlocked position to the second locked position and stay in the second locked position. At this time, when the latch applies a push force to the latch component 200 again and causes the latch component 200 to rotate counterclockwise, the latch component 200 will move to the first locked position and be held in the first locked position.

[0082] Those skilled in the art should know that when the latch applies a large force to the bolt member 200, the bolt member 200 will move directly from the unlocked position to the first locked position, and will not stay in the second locked position.

[0083] See again Figure 4The unlocking lever component 400 disclosed herein includes a first unlocking lever feature 401 and a second unlocking lever feature 402. The first unlocking lever feature 401 is formed as an arc-shaped bend, and is used to engage with and pressurize a stop component 500. Specifically, the unlocking lever component 400 can drive the stop component 500 from a second stop position to a first stop position, and during the movement of the stop component 500 from the first stop position to the second stop position, it can drive the unlocking lever component 400 to rotate counterclockwise.

[0084] The second feature 402 of the unlocking lever is formed as a flange, which is used to limit the position of the pawl component 300. In a preferred embodiment, the pawl component 300 is rotatable relative to the unlocking lever component 400; that is, the pawl component 300 is not always stationary with respect to the unlocking lever component 400. Specifically, when the pawl component 300 is in the first pawl position, it will be limited by the locking tongue component 200 and cannot rotate further counterclockwise (towards...). Figure 4 (As shown in the direction), however, the unlocking lever component 400 will continue to rotate counterclockwise under the drive of the stop component 500. At this time, the unlocking lever component 400 will rotate relative to the pawl component 200, resulting in a preset distance between the pawl component 300 and the second feature 402 of the unlocking lever. In a specific embodiment, this preset distance can be 0.5mm, and then the unlocking lever component 400 will be positioned by components such as the limiting boss.

[0085] In some embodiments, the front cover lock further includes a stop return spring 510, which provides a return force to the stop member 500 so that the stop member 500 has a tendency to move toward the second stop position. That is, at least part of the force during the movement of the stop member 500 from the first stop position to the second stop position is provided by the stop return spring 510.

[0086] See again Figure 4 The front cover lock of this disclosure further includes a pawl return spring 310, which provides a return force to the pawl component 300 so that the pawl component 300 has a tendency to move toward the first pawl position. That is, at least part of the force of the pawl component 300 during its movement toward the first pawl position is provided by the pawl return spring 310, and at least part of the force is provided by the stop return spring 510.

[0087] In other words, when the pawl return spring 310 drives the pawl component 300 to move from the second pawl position to the first pawl position, the pawl component 300 drives the unlocking lever component 400 to rotate. Simultaneously, the return force provided by the pawl return spring 310 ensures that the pawl component 300 and the unlocking lever component 400 are in pressurized contact. Consequently, when the unlocking lever component 400 rotates clockwise, the pawl component 300 will rotate simultaneously with the unlocking lever component 400.

[0088] like Figures 1 to 4 As shown, the front cover lock of this disclosure also includes an electric unlocking assembly 600, which is used to drive the unlocking lever assembly 400 to rotate so that the pawl assembly 300 can move from the first pawl position to the second pawl position.

[0089] In other words, the front cover lock of this disclosure can be unlocked not only manually (at which time one end of the unlocking lever component 400 can be connected to an unlocking cable) but also electrically. Similarly, when the front cover lock of this disclosure is electrically unlocked, the unlocking lever component 400 needs to be triggered twice to unlock the front cover lock.

[0090] In one specific embodiment, the electric unlocking assembly 600 may include components such as an unlocking motor 610, an unlocking worm gear 620, and an unlocking cam 630.

[0091] The unlocking motor 610 is used to provide unlocking power, wherein a worm gear is mounted on the drive shaft of the unlocking motor 610; the worm gear cooperates with the unlocking worm wheel 620 to drive the unlocking worm wheel 620 to rotate.

[0092] The unlocking cam 630 is driven and rotated by the unlocking worm gear 620, wherein the unlocking cam 630 cooperates with the unlocking lever component 400 to push the unlocking lever component 400 to rotate. In a preferred embodiment, the unlocking worm gear 620 and the unlocking cam 630 are integrally formed.

[0093] In this disclosure, when the locking tongue component 200 engages with the stop component 500, the locking tongue component 200 applies a pushing force to the stop component 500. This pushing force causes the stop component 500 to tend to move towards the second stop position. As a result, after the external force applied to the unlocking lever component 400 disappears, the locking tongue component 200 will not jam with the stop component 500, and the stop component 500 will not move from the first stop position to the second stop position.

[0094] According to another aspect of this disclosure, a motor vehicle is provided, which includes the aforementioned hood lock.
