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," above, "" upper, "" above, "" higher, "and" side (e.g., as in "sidewall") to describe one component's relationship to another (other) component as shown 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" may 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.

Fig. 1 to 3 are different state structure diagrams of a front cover lock according to an embodiment of the present disclosure.

As shown in fig. 1-3, the front cover lock of the present disclosure may be secured to a vehicle body to lock the front cover to the vehicle body when in use. The front cover lock of the present disclosure has a double-pull unlocking function, i.e., when a handle (not shown in the drawing) provided in a driver's compartment of a vehicle is pulled twice, the handle can cause the driving part 400 to act, further causing the front cover lock to be opened. Of course, the front cover lock in the present disclosure may be opened electrically, for example, by triggering a trigger switch or the like provided in the driver's cabin, and then by rotating a driving motor or the like, the driving member 400 is operated. In addition, the front cover lock of the present disclosure may also be provided to the front cover. The present disclosure is not limited in this regard.

Specifically, the front cover lock of FIG. 1 is shown in a fully locked condition with the pawl member 300 in the first position and holding the tongue member 200 in the first locked position, the front cover lock of FIG. 2 is shown in a semi-locked condition with the pawl member 300 in the second position and holding the tongue member 200 in the second locked position, and the front cover lock of FIG. 3 is shown in a fully unlocked condition, i.e., unlocked condition, with the pawl member 300 in the third position and the tongue member 200 in the open position.

In one particular embodiment, the front cover lock of the present disclosure may include a lock housing 100, a deadbolt assembly 200, a pawl assembly 300, a drive assembly 400, and a push assembly 500, among other components.

Fig. 4 is a schematic structural view of a lock case and a support member of a front cover lock according to one embodiment of the present disclosure.

The lock case 100 is formed substantially in a plate-like structure, and in use, the fixing of the front cover lock of the present disclosure can be achieved by fixing the lock case 100 to the vehicle body. In the present disclosure, the lock case 100 is formed as a part of a housing of a front cover lock, and for example, the front cover lock may further include an upper cover (not shown in the drawings), and the lock case 100 may be fixed to the upper cover and together form the housing of the front cover lock.

The lock case 100 is provided with a first shaft portion 110 and a second shaft portion 120, and preferably one end of the first shaft portion 110 may be fixed to the lock case 100 and the other end may be fixed to the upper cover, of course, the other end of the first shaft portion 110 may not be fixed to the upper cover, and similarly, one end of the second shaft portion 120 may be fixed to the lock case 100 and the other end may be fixed to the upper cover.

The central axis of the first shaft 110 is a first rotation axis, and the axis of the second shaft 120 is a second rotation axis. More preferably, the first axis of rotation is arranged parallel to the second axis of rotation.

The first shaft portion 110 and the second shaft portion 120 are provided with a support member 130. Specifically, the upper end of the first shaft portion 110 is provided to the support member 130, and is preferably fixed to the support member 130. Meanwhile, the support member 130 is provided with a through hole, and at least a portion of the second shaft portion 120 is located in the through hole of the support member 130, so that the position of the support member 130 can be limited by the second shaft portion 120, and the support member 130 can be fixedly connected with the lock case 100.

Fig. 5-7 are schematic views of different state structures of a tongue component and a pawl component according to one embodiment of the present disclosure.

As shown in fig. 5-7, the latch bolt assembly 200 has a first axis of rotation and includes a first latched position, a second latched position, and an open position. In other words, the latch bolt assembly 200 is rotatably disposed at the first shaft portion 110, and as the latch bolt assembly 200 is rotated counterclockwise (in the direction of fig. 5-7), the latch bolt assembly 200 may be sequentially in a first latched position, a second latched position, and an open position.

The first locking position may also be referred to as the full locking position, and the second locking position may also be referred to as the half locking position.

The pawl member 300 has a second axis of rotation and has a first position, a second position and a third position. In other words, the pawl member 300 is rotatably provided to the second shaft portion 120, and the pawl member 300 can be driven to move from the first position to the second position or from the second position to the third position.

Specifically, in the condition shown in fig. 5, the tongue component 200 is in the first latched position and the pawl component 300 is in the first position, with one of the pawl component 300 fingers being able to engage one of the peripheral surfaces of the tongue component 200 and retain the tongue component 200 in the first latched position.

When the pawl member 300 is driven and rotated counterclockwise, it can move from the first position to the second position. In the condition shown in fig. 6, the pawl member 300 is in the second position, in which the pawl member 300 is capable of disengaging from the tongue member 200 (the tongue member 200 in the first latched position) to permit the tongue member 200 to rotate counterclockwise to move from the first latched position shown in fig. 6 to the second latched position. At the same time, in the second latched position, one pawl portion of the pawl member 300 is capable of engaging another feature of the peripheral surface of the tongue member 200 and restraining the tongue member 200 in the second latched position.

When the latch bolt assembly 200 is in the second latched position, the pawl assembly 300 can be further actuated to move from the second position to a third position in which the pawl assembly 300 can be disengaged from the latch bolt assembly 200 (the latch bolt assembly 200 in the second latched position) to allow the latch bolt assembly 200 to be rotated further counterclockwise to move from the second latched position to an open position in which the front cover of the vehicle is released.

Structurally, the pawl member 300 of the present disclosure may include a pawl first portion 310, the pawl first portion 310 being formed as one arm of the pawl member 300 and the pawl first portion 310 having a force-receiving surface thereon, the push assembly 500 being capable of applying a pushing force to the force-receiving surface to push the pawl member 300 to rotate, and more preferably, the pawl first portion 310 being formed with a burring portion 320, one surface of the burring portion 320 being formed as a force-receiving surface, thereby enabling the pawl member 300 to be easily engaged with the push assembly 500 to be described below to be driven by the push assembly 500.

Fig. 8 is a schematic structural view of a first spring according to one embodiment of the present disclosure.

In this disclosure, the power for the counterclockwise rotation of the latch bolt assembly 200 may be provided by the first spring 600.

In the present disclosure, the first spring 600 may be a torsion spring, one end of which may be stopped on the latch bolt member 200, and the other end of which may be stopped on the second shaft portion 120 or on the support member 130.

More preferably, as shown in fig. 8, the support member 130 may include a spring bracket 131, at least part of the spring bracket 131 being located in the winding space of the first spring 600, and preventing the first spring 600 from being excessively displaced in the radial direction by contact of the spring bracket 131 with the first spring 600.

In a specific embodiment, when the latch bolt assembly 200 is in the first latched position, the connection of the first spring 600 to the latch bolt assembly 200 and the connection of the first spring 600 to the second shaft portion 120 are disposed proximate to each other, while the spring bracket 131 is disposed away from the connection of the first spring 600 to the latch bolt assembly 200 and the connection of the first spring 600 to the second shaft portion 120, whereby the spring bracket 131 is capable of more stably supporting the first spring 600.

Fig. 9 is a schematic structural view of a second spring according to one embodiment of the present disclosure.

In this disclosure, when the latch bolt assembly 200 is no longer blocking the pawl assembly 300, for example, the latch bolt assembly 200 is actuated by an external force, i.e., during closing of the front cover, a shackle mounted to the front cover will apply an external force to the latch bolt assembly 200, at which time the latch bolt assembly 200 will move from the open position to the second latched position, or further, from the second latched position to the first latched position, at which time the latch bolt assembly 200 will no longer continue to block the pawl assembly 300, the pawl assembly 300 will move from the third position to the second position, or further, from the second position to the first position, under the influence of the second spring 700.

More preferably, the second spring 700 may be wound around the second shaft portion 120, and one end of the second spring 700 is stopped on the pawl member 300 and the other end thereof is stopped on the support member 130.

Fig. 10 is a schematic structural view of a driving part according to an embodiment of the present disclosure.

In the present disclosure, the driving part 400 is rotatably disposed at the second shaft portion 120, whereby the driving part 400 has a second rotation axis. Of course, the drive member 400 may also have a rotational axis that is different from the second rotational axis.

More specifically, a through hole is opened at the middle of the driving part 400, and at least part of the second shaft part 120 is positioned in the through hole of the driving part 400, whereby the driving part 400 can be rotated counterclockwise when a rightward pulling force is applied to one end of the driving part 400 (in the direction shown in fig. 10).

Wherein the middle of the driving part 400 does not refer to a position of the geometric center of the driving part 400, but refers to a portion between both ends (i.e., one end and the other end) of the driving part 400.

In a specific embodiment, one end of the driving part 400 may be connected to the driving wire, and when the handle is operated, the driving part 400 can be rotated by transmitting a pulling force through the driving wire, whereby the driving part 400 includes an initial position and a driving position, and in the state shown in fig. 10, the driving part 400 is in the initial position.

Also, the support member 130 may include a limit boss 132, the limit boss 132 for limiting the driving member 400 to the driving position. In other words, when the driving part 400 is driven to rotate, the driving part 400 can be limited in position by the limiting boss 132 of the supporting part 130, so that it cannot be rotated further, to prevent the pawl part 400 from being in the third position and the front cover lock of the present disclosure from being in the open state by one operation.

In a preferred embodiment, the driving part 400 is provided with an extension 410, which extension 410 extends in the second rotation axis direction from the plane in which the driving part 400 is located, whereby the extension 410 can be engaged with the limit boss 132 of the supporting part 130 and is limited in position by the supporting part 130 when the supporting part 130 is mounted on a different plane than the driving part 400. Preferably, the extension 410 can be integrally formed with the driving part 400.

Fig. 11 is a schematic structural view of a third spring according to one embodiment of the present disclosure.

More preferably, the driving part 400 is restored by a restoring force provided by the third spring 800, and preferably, the third spring 800 is provided as a torsion spring, and the driving part 400 is movable from the driving position to the initial position by the restoring force of the third spring 800. Accordingly, during the movement of the driving part 400 from the driving position to the initial position, the driving part 400 is not provided with a pulling force by the driving pulling wire.

In the present disclosure, the third spring 800 can be wound on the second shaft portion 120, and one end thereof can be stopped on the extension portion 410 of the driving part 400, and the other end thereof can be stopped on the supporting part 130, thereby enabling the third spring 800 to apply a restoring force to the driving part 400.

In the present disclosure, the support member 130 may further include a blocking portion 133, and the other end of the second spring 700 and/or the other end of the third spring 800 may be stopped against the blocking portion 133.

The driving part 400 drives the pawl part 300 to rotate by the push assembly 500, wherein the push assembly 500 is provided at the other end of the driving part 400.

Fig. 12 to 14 are schematic structural views of a pushing assembly according to an embodiment of the present disclosure.

As shown in fig. 12 to 14, the push assembly 500 includes a first push member 510 and a second push member 520, wherein the first push member 510 and the second push member 520 are rotatably provided to the driving member 400, thereby facilitating the installation of the first push member 510 and the second push member 520.

More preferably, the first pushing member 510 and the second pushing member 520 have the same rotation axis, i.e., the first pushing member 510 and the second pushing member 520 may be mounted to the driving member 400 using the same shaft member, whereby the front cover lock of the present disclosure has fewer parts and accordingly higher reliability.

Structurally, the first pushing member 510 and the second pushing member 520 of the present disclosure are each generally V-shaped, i.e., each have two arms.

Wherein the first pushing member 510 includes a first force application surface 511, the first force application surface 511 may be formed as an end surface of one arm portion of the first pushing member 510.

When the pawl member 300 is in the first position, the drive member 400 is in the initial position and the first urging member 510 has a first urging surface 511 in contact with or adjacent to the force receiving surface of the pawl member 300, the first urging surface 511 being capable of urging force against the force receiving surface when the drive member 400 is driven.

That is, upon the first rotation of the driving member 400 of the present disclosure, the driving member 400 moves from the initial position to the driving position, and the pawl member 300 is driven from the first position to the second position by the first pushing member 510.

Meanwhile, since the first pushing member 510 can be kept in pressure contact with the pawl member 300 during the movement of pushing the pawl member 300, accordingly, the first pushing member 510 does not generate a clockwise or counterclockwise motion (in the direction shown in fig. 10) and is disengaged from the pawl member 300.

More preferably, a stepped portion is formed on one arm portion of the first pushing member 510, and accordingly, the first urging surface 511 is formed as one surface of the stepped portion, at which time the burring 320 of the pawl member 300 can be caught in the stepped portion, and accordingly, clockwise rotation of the first pushing member 510 is also prevented.

Meanwhile, the lock case 100 is provided with a limiting member 140, and preferably, the limiting member 140 may be integrally formed with the lock case 100. Accordingly, the first push member 510 includes a stop surface 512, the stop surface 512 being adapted to engage the stop member 140 and to limit the first push member 510 to a first push position, wherein the first force application surface 511 of the first push member 510 is adapted to engage (contact or be adjacent to) the force application surface of the pawl member 300 when the first push member 510 is in the first push position and the pawl member 300 is in the first position. Meanwhile, when the pawl member 300 is moved away from the first position, such as when the pawl member 300 is in the second position and the first urging member 510 is in the first urging position, the first urging surface 511 of the first urging member 510 is spaced apart from the urging surface of the pawl member 300.

In the present disclosure, when the driving part 400 is moved away from the initial position, the first pushing part 510 is separated from the limiting part 140 to allow the first pushing part 510 to move from the first pushing position to the second pushing position, or, in other words, the first pushing part 510 is allowed to move from the first pushing position to the second pushing position. The "allowing the first push member 510 to move from the first push position to the second push position" of the present disclosure does not necessarily mean that the first push member 510 must move from the first push position to the second push position, but the first push member 510 may move from the first push position to the second push position, and whether the first push member 510 moves from the first push position to the second push position depends on the position of the pawl member 300.

Specifically, when the pawl member 300 is in the first position, the first push member 510 will not move (rotate) from the first push position to the second push position at this time, i.e., when the pawl member 300 is in the first position, the pawl member 300 cooperates with the first push member 510 to disallow movement of the first push member 510 from the first push position to the second push position.

Accordingly, when the pawl member 300 is in the second position, the first push member 510 will move to (rotate to) the second push position where the second push member 520 can push the pawl member 300 from the second position to the third position. In other words, when the pawl member 300 is in the second position, the first push member 510 can move from the first push position to the second push position at this time because the pawl member 300 is separated from the first push member 510.

In the present disclosure, the second urging member 520 includes a second urging surface 521, and when the pawl member 300 is in the second position and the driving member 400 is moved away from the initial position, the urging assembly 500 changes position with respect to the driving member 400 and brings the second urging surface 521 of the second urging member 520 into contact with the urging surface of the pawl member 300 to apply urging force to the urging surface.

Specifically, when the driving member 400 is driven a second time, the second pushing member 520 pushes the pawl member 300 to move, and at this time, the first pushing member 510 is not in contact with or in transmission with the pawl member 300.

In the second pushing position, the first pushing member 510 is disposed at the stopper 420 of the driving member 400 at a restricting position, i.e., the position shown in fig. 10.

Specifically, in the direction shown in fig. 10, when the first pushing member 510 is away from the limiting member 140 and the pawl member 300 is located at the second position, the first pushing member 510 is rotated clockwise and the first pushing member 510 is abutted against the limiting block 420 of the driving member 400, whereby the first pushing member 510 can be stably maintained at the second pushing position.

In the present disclosure, the first push member 510 is provided with a limit projection 513, and the second push member 520 includes a first push arm 522, and the first push arm 522 is engaged with the limit projection 513 of the first push member 510, so that the first push member 510 is closely attached to the second push member 520.

Specifically, the shaft member is sleeved with a fourth spring 900, one end of the fourth spring 900 is stopped on the first pushing arm 522, the other end of the fourth spring 900 is stopped on the driving member 400, for example, on the stopper 420 of the driving member 400, and at this time, the other end of the fourth spring 900 and the first pushing member 510 are respectively located at two sides of the stopper 420.

The second pushing member 520 includes a second pushing arm 523, and the second pushing arm 523 is capable of pushing the pawl member 300 when the first pushing arm 522 is located at the second pushing position. Preferably, the reaction force applied by the pawl member 300 to the second push member 520 can cause the second push member 520 to rotate clockwise, at which time the first push arm 522 of the second push member 520 can apply an external force to the limit projection 513 and cause the first push member 510 to also have a clockwise movement tendency, whereby the first push member 510 can more closely abut the limit block 420 without disengaging from the limit block 420.

The portion of the second push arm 523 in contact with the pawl member 300 protrudes outside the first push member 510, that is, the second push arm 523 is longer than one arm of the first push member 510, so that only the second push arm 523 is used for driving at the time of the second driving.

In general, when the pawl member 300 is in the first position, the driving member 400 moves from the initial position to the driving position, and the pawl member 300 can be pushed to the second position by the first pushing member 510, when the pawl member 300 is in the second position, the driving member 400 moves from the initial position to the driving position, and the pawl member 300 is pushed to the third position away from the second position by the second pushing member 520, and when the pawl member 300 is in the third position, the tongue member 200 is released, thereby achieving double-pull unlocking of the front cover lock.

The front cover lock of the present disclosure may also include a deadbolt position switch 150, the deadbolt position switch 150 being triggered by the deadbolt assembly 200 when the deadbolt assembly 200 is in the first locked position.

According to another aspect of the present disclosure, there is provided a motor vehicle comprising the front cover lock as described above.
