Description
Technical Field
[0001] This disclosure relates to a front cover lock and a motor vehicle, belonging to the field of vehicle door lock technology. Background Technology
[0002] If the hood is improperly opened while the vehicle is in motion, such as by accidentally operating the hood lock handle, a serious accident could occur. Therefore, hood locks are typically opened by operating the handle twice.
[0003] Chinese invention patent publication CN104204387A provides a double pull latch for, for example, a hood closure plate. The double pull latch provided in this publication has a complex fit, which results in a low lifespan.
[0004] Therefore, it is necessary to develop a new front cover lock to solve the above-mentioned technical problems. Summary of the Invention
[0005] To solve one of the aforementioned technical problems, this disclosure provides a front cover lock and a motor vehicle.
[0006] According to one aspect of this disclosure, a front cover lock is provided, comprising:
[0007] A locking tongue component, the locking tongue component having a first rotation axis and including at least a first locking position and a second locking position;
[0008] A pawl component having a second axis of rotation, which holds a locking tongue component in a first locked position when the pawl component is in a first position, and holds a locking tongue component in a second locked position when the pawl component is in a second position.
[0009] A driving component, the driving component including an initial position and a driving position; and
[0010] A pushing assembly is provided, wherein the driving component drives the pawl component to rotate via the pushing assembly. The pushing assembly includes a first pushing component and a second pushing component. When the pawl component is in a first position, the driving component moves from an initial position to a driving position and pushes the pawl component to a second position via the first pushing component. When the pawl component is in the second position, the driving component moves from the initial position to the driving position and pushes the pawl component to a third position away from the second position via the second pushing component. When the pawl component is in the third position, the locking tongue component is released.

[0018] According to at least one embodiment of the front cover lock of the present disclosure, the first pushing member includes a limiting surface for engaging with a limiting member and limiting the first pushing member to a first pushing position, wherein, in the first pushing position, a first force-applying surface of the first pushing member can engage with a force-receiving surface of the pawl member.
[0019] According to at least one embodiment of the front cover lock of the present disclosure, the limiting member is disposed on the lock housing.
[0020] According to at least one embodiment of the front cover lock of the present disclosure, when the drive member leaves the initial position, the first push member separates from the limiting member to allow the first push member to move from the first push position to the second push position.
[0021] According to at least one embodiment of the front cover lock of the present disclosure, when the pawl component is in a first position, the pawl component cooperates with the first push component to prevent the first push component from moving from the first push position to a second push position.
[0022] According to at least one embodiment of the front cover lock of the present disclosure, when the pawl component is in the second position, the pawl component is separated from the first pushing component, and the first pushing component moves from the first pushing position to the second pushing position.
[0023] According to at least one embodiment of the front cover lock of the present disclosure, in the second push position, the first push member is disposed at the limiting position of the limiting block of the drive member.
[0024] According to at least one embodiment of the front cover lock of the present disclosure, the first pushing member is provided with a limiting protrusion, and the second pushing member includes a first pushing arm portion, which cooperates with the limiting protrusion of the first pushing member to make the first pushing member and the second pushing member fit tightly together.
[0025] According to at least one embodiment of the front cover lock of the present disclosure, the second pushing member includes a second pushing arm; when the first pushing arm is in a second pushing position, the second pushing arm is capable of pushing the pawl member.
[0026] According to at least one embodiment of the front cover lock of the present disclosure, the portion of the second push arm that contacts the pawl component extends outside the first push component.
[0027] The front cover lock according to at least one embodiment of the present disclosure further includes:
[0028] A support component, which is disposed on the lock housing.

[0073] 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.
[0074] 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.
[0075] 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.
[0076] 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.
[0077] 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.
[0078] 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.
[0079] 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.
[0080] Figures 1 to 3 This is a schematic diagram of the different states of the front cover lock according to one embodiment of the present disclosure.
[0081] like Figures 1 to 3 As shown, the hood lock of this disclosure can be fixed to the vehicle body during use to lock the hood to the vehicle body. The hood lock of this disclosure has a double-pull unlocking function; that is, when a handle (not shown in the figure) located inside the driver's compartment is pulled twice, the handle can actuate the drive component 400, further opening the hood lock. Of course, the hood lock of this disclosure can also be opened electrically, for example, by triggering a trigger switch or other component located inside the driver's compartment, which in turn actuates the drive component 400 through the rotation of a drive motor or other component. Furthermore, the hood lock of this disclosure can also be installed on the hood. This disclosure is not limited to this.
[0082] Specifically Figure 1The front cover lock shown is in the fully locked state, at which time the pawl component 300 is in the first position and holds the bolt component 200 in the first locked position; Figure 2 The front cover lock shown is in a half-locked state, at which time the pawl component 300 is in the second position and holds the bolt component 200 in the second locked position; Figure 3 The front cover lock shown is in the fully open state, i.e., the unlocked state. At this time, the pawl component 300 is in the third position, and the bolt component 200 is in the open position.
[0083] In one specific embodiment, the front cover lock of this disclosure may include components such as a lock housing 100, a lock tongue component 200, a pawl component 300, a drive component 400, and a push assembly 500.
[0084] Figure 4 This is a structural schematic diagram of the lock housing and support components of a front cover lock according to one embodiment of the present disclosure.
[0085] The lock housing 100 is generally formed as a plate-like structure. In use, the front cover lock of this disclosure can be fixed by fixing the lock housing 100 to the vehicle body. In this disclosure, the lock housing 100 is formed as part of the housing of the front cover lock. For example, the front cover lock may also include a top cover (not shown in the figure). The lock housing 100 can be fixed to the top cover and together form the housing of the front cover lock.
[0086] The lock housing 100 is provided with a first shaft portion 110 and a second shaft portion 120; preferably, one end of the first shaft portion 110 can be fixed to the lock housing 100 and the other end can be fixed to the top cover; of course, the other end of the first shaft portion 110 may not be fixed to the top cover; similarly, one end of the second shaft portion 120 is also fixed to the lock housing 100 and the other end can also be fixed to the top cover.
[0087] The central axis of the first shaft portion 110 is the first rotation axis, and the axis of the second shaft portion 120 is the second rotation axis. More preferably, the first rotation axis and the second rotation axis are arranged parallel to each other.
[0088] A support member 130 is provided on the first shaft portion 110 and the second shaft portion 120. Specifically, the upper end of the first shaft portion 110 is disposed on the support member 130, and preferably is fixedly disposed on the support member 130. At the same time, the support member 130 has 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. Thus, the position of the support member 130 can be restricted by the second shaft portion 120, so that the support member 130 can be fixedly connected to the lock housing 100.
[0089] Figures 5 to 7 This is a schematic diagram showing the different states of the locking tongue component and the pawl component according to one embodiment of the present disclosure.
[0090] like Figures 5 to 7 As shown, the latch component 200 has a first axis of rotation and includes a first locked position, a second locked position, and an open position. In other words, the latch component 200 is rotatably disposed on the first shaft portion 110, and as the latch component 200 rotates counterclockwise (towards...), the latch component 200... Figures 5 to 7 (direction), the locking tongue component 200 can be in the first locked position, the second locked position and the open position in sequence.
[0091] The first locking position can also be called the fully locked position, and the second locking position can also be called the half-locked position.
[0092] The pawl component 300 has a second axis of rotation and has a first position, a second position, and a third position. In other words, the pawl component 300 is rotatably disposed on the second shaft portion 120, and the pawl component 300 can be driven to move from the first position to the second position, or can move from the second position to the third position.
[0093] Specifically, in Figure 5 In the state shown, the latch component 200 is in the first locking position, and the pawl component 300 is in the first position. At this time, one pawl of the pawl component 300 can engage with a feature on the circumferential surface of the latch component 200 and restrict the latch component 200 to the first locking position.
[0094] When the pawl component 300 is driven and rotates counterclockwise, it can move from the first position to the second position. Figure 6 In the indicated state, the pawl component 300 is in the second position, at which point the pawl component 300 can disengage from the latch component 200 (the latch component 200 in the first locking position), allowing the latch component 200 to rotate counterclockwise to... Figure 6 The device moves from the first locking position to the second locking position. Simultaneously, in the second locking position, one pawl of the pawl member 300 engages with another feature on the circumferential surface of the latch member 200, thus restricting the latch member 200 to the second locking position.
[0095] When the latch member 200 is in the second locked position, the pawl member 300 can be further driven to move from the second position to a third position, in which the pawl member 300 can disengage from the latch member 200 (the latch member 200 in the second locked position) to allow the latch member 200 to rotate further counterclockwise to move from the second locked position to the open position; in the open position, the hood of the vehicle is released.
[0096] Structurally, the pawl component 300 of this disclosure may include: a first pawl portion 310, which is formed as an arm of the pawl component 300, and has a force-receiving surface. The push assembly 500 can apply a thrust to the force-receiving surface to drive the pawl component 300 to rotate. More preferably, a flange portion 320 is formed on the first pawl portion 310, and one surface of the flange portion 320 forms a force-receiving surface, thereby enabling the pawl component 300 to easily cooperate with the push assembly 500 described below to be driven by the push assembly 500.
[0097] Figure 8 This is a schematic diagram of the structure of a first spring according to one embodiment of the present disclosure.
[0098] In this disclosure, the power for the counterclockwise rotation of the latch component 200 can be provided by the first spring 600.
[0099] In this disclosure, the first spring 600 may be a torsion spring, one end of which may stop on the locking tongue member 200, and the other end of which may stop on the second shaft portion 120 or on the support member 130.
[0100] More preferably, such as Figure 8 As shown, the support member 130 may include a spring bracket 131, at least a portion of which is located within the winding space of the first spring 600, and the contact between the spring bracket 131 and the first spring 600 prevents the first spring 600 from generating excessive radial displacement.
[0101] In one specific embodiment, when the latch component 200 is in the first locked position, the connection between the first spring 600 and the latch component 200 and the connection between the first spring 600 and the second shaft portion 120 are arranged close to each other, while the spring bracket 131 is arranged away from the connection between the first spring 600 and the latch component 200 and the connection between the first spring 600 and the second shaft portion 120. Thus, the spring bracket 131 can more stably support the first spring 600.
[0102] Figure 9 This is a schematic diagram of the structure of a second spring according to one embodiment of the present disclosure.
[0103] In this disclosure, when the latch component 200 no longer stops the pawl component 300, for example, when the latch component 200 is driven by an external force, that is, during the process of closing the front cover, the latch mounted on the front cover will apply an external force to the latch component 200. At this time, the latch component 200 will move from the open position to the second locking position, or further, from the second locking position to the first locking position. At this time, the latch component 200 will no longer stop the pawl component 300. The pawl component 300 will move from the third position to the second position under the action of the second spring 700, or further, from the second position to the first position.
[0104] More preferably, the second spring 700 can be wound around the second shaft portion 120, and one end of the second spring 700 stops on the pawl member 300, and the other end stops on the support member 130.
[0105] Figure 10 This is a schematic diagram of the structure of a drive component according to one embodiment of the present disclosure.
[0106] In this disclosure, the drive member 400 is rotatably disposed on the second shaft portion 120, thereby giving the drive member 400 a second axis of rotation. Of course, the drive member 400 may also have a axis of rotation different from the second axis of rotation.
[0107] More specifically, the drive component 400 has a through hole in its middle, and at least a portion of the second shaft portion 120 is located within the through hole of the drive component 400, thereby allowing the drive component 400 to be pulled to the right when a pulling force is applied to one end (to... Figure 10 (in the direction shown), the drive component 400 is capable of producing counterclockwise rotation.
[0108] The middle part of the drive component 400 does not refer to the position of the geometric center of the drive component 400, but rather to the part between the two ends (i.e., one end and the other end) of the drive component 400.
[0109] In one specific embodiment, one end of the drive component 400 can be connected to a drive cable. When the handle is operated, a pulling force can be transmitted through the drive cable, causing the drive component 400 to rotate. Thus, the drive component 400 includes an initial position and a driven position. Figure 10 In the state shown, the drive unit 400 is in the initial position.
[0110] Furthermore, the support member 130 may include a limiting boss 132 for restricting the drive member 400 in the drive position. In other words, when the drive member 400 is driven to rotate, the drive member 400 can be restricted in position by the limiting boss 132 of the support member 130, thereby preventing further rotation and preventing the pawl member 400 from being placed in the third position in a single operation, thus causing the front cover lock of this disclosure to be in the open state.
[0111] In a preferred embodiment, the drive component 400 is provided with an extension 410 that extends from the plane of the drive component 400 along the second rotation axis. Thus, when the support component 130 and the drive component 400 are mounted on different planes, the extension 410 can engage with the limiting boss 132 of the support component 130 and be positioned by the support component 130. Preferably, the extension 410 can be integrally formed with the drive component 400.
[0112] Figure 11 This is a schematic diagram of the structure of a third spring according to one embodiment of the present disclosure.
[0113] More preferably, the drive component 400 is reset by the reset force provided by the third spring 800. Preferably, the third spring 800 is a torsion spring, and under the action of the reset force of the third spring 800, the drive component 400 can move from the drive position to the initial position. Accordingly, during the process of the drive component 400 moving from the drive position to the initial position, no tension force is provided to the drive component 400 through the drive cable.
[0114] In this disclosure, the third spring 800 can be wound around the second shaft portion 120, and one end of it can be stopped on the extension portion 410 of the drive member 400, and the other end of it can be stopped on the support member 130, thereby enabling the third spring 800 to apply a restoring force to the drive member 400.
[0115] In this disclosure, the support member 130 may also include a blocking portion 133, on which the other end of the second spring 700 and / or the other end of the third spring 800 can be stopped.
[0116] The drive component 400 drives the pawl component 300 to rotate by pushing component 500, wherein the pushing component 500 is disposed at the other end of the drive component 400.
[0117] Figures 12 to 14 This is a schematic diagram of the structure of a driving component according to one embodiment of the present disclosure.
[0118] like Figures 12 to 14As shown, the pushing assembly 500 includes a first pushing component 510 and a second pushing component 520; wherein the first pushing component 510 and the second pushing component 520 are rotatably disposed on the driving component 400, thereby facilitating the installation of the first pushing component 510 and the second pushing component 520.
[0119] More preferably, the first pushing member 510 and the second pushing member 520 have the same axis of rotation, that is, the first pushing member 510 and the second pushing member 520 can be mounted on the drive member 400 using the same shaft component. As a result, the front cover lock of this disclosure has fewer parts and correspondingly higher reliability.
[0120] Structurally, both the first pushing member 510 and the second pushing member 520 of this disclosure are generally V-shaped, that is, both have two arms.
[0121] The first pushing component 510 includes a first force-applying surface 511, which can be formed as the end face of an arm of the first pushing component 510.
[0122] When the pawl component 300 is in the first position, the drive component 400 is in the initial position, and the first force-applying surface 511 of the first push component 510 is in contact with or adjacent to the force-receiving surface of the pawl component 300. When the drive component 400 is driven, the first force-applying surface 511 can apply a thrust to the force-receiving surface.
[0123] In other words, when the drive component 400 of this disclosure rotates for the first time, the drive component 400 moves from the initial position to the drive position, and drives the pawl component 300 from the first position to the second position through the first push component 510.
[0124] Meanwhile, because the first pushing component 510 maintains pressure contact with the pawl component 300 during the movement of the pawl component 300, the first pushing component 510 will not perform clockwise or counterclockwise movements (in order to...). Figure 10 (in the direction shown), and disengage from the pawl component 300.
[0125] More preferably, a step is formed on one arm of the first pushing member 510, and correspondingly, the first force-applying surface 511 is formed as a surface of the step. In this case, the flange 320 of the pawl member 300 can be locked in the step, which also prevents the clockwise rotation of the first pushing member 510.
[0126] Meanwhile, a limiting member 140 is provided on the lock housing 100; preferably, the limiting member 140 can be integrally formed with the lock housing 100. Correspondingly, the first pushing member 510 includes a limiting surface 512, which is used to cooperate with the limiting member 140 and restrict the first pushing member 510 to a first pushing position. When the first pushing member 510 is in the first pushing position and the pawl member 300 is in the first position, the first force-applying surface 511 of the first pushing member 510 can cooperate (contact or be adjacent to) the force-receiving surface of the pawl member 300. Meanwhile, when the pawl member 300 leaves the first position, for example, when the pawl member 300 is in the second position and the first pushing member 510 is in the first pushing position, the first force-applying surface 511 of the first pushing member 510 and the force-receiving surface of the pawl member 300 are spaced apart.
[0127] In this disclosure, after the drive component 400 leaves the initial position, the first push component 510 separates from the limiting component 140 to allow the first push component 510 to move from the first push position to the second push position, or in other words, the first push component 510 is allowed to move from the first push position to the second push position. The statement "allowing the first push component 510 to move from the first push position to the second push position" does not necessarily mean that the first push component 510 will definitely move from the first push position to the second push position. Rather, it means that the first push component 510 can move from the first push position to the second push position, and whether the first push component 510 moves from the first push position to the second push position depends on the position of the pawl component 300.
[0128] Specifically, when the pawl component 300 is in the first position, the first push component 510 will not move from the first push position to (rotate to) the second push position; that is, when the pawl component 300 is in the first position, the pawl component 300 cooperates with the first push component 510 to prevent the first push component 510 from moving from the first push position to the second push position.
[0129] Accordingly, when the pawl component 300 is in the second position, the first pushing component 510 will move to (rotate to) the second pushing position. In this second pushing position, the second pushing component 520 can push the pawl component 300 from the second position to the third position. In other words, when the pawl component 300 is in the second position, since the pawl component 300 is separated from the first pushing component 510, the first pushing component 510 can move from the first pushing position to the second pushing position.
[0130] In this disclosure, the second pushing component 520 includes a second force-applying surface 521. When the pawl component 300 is in the second position and the driving component 400 leaves the initial position, the pushing component 500 undergoes a positional change relative to the driving component 400, causing the second force-applying surface 521 of the second pushing component 520 to contact the force-receiving surface of the pawl component 300, so as to apply a thrust to the force-receiving surface.
[0131] Specifically, when the drive component 400 is driven for the second time, the second push component 520 pushes the pawl component 300 to move. At this time, the first push component 510 does not contact or transmit power with the pawl component 300.
[0132] In the second pushing position, the first pushing component 510 is positioned at the limiting position of the limiting block 420 of the driving component 400; this second pushing position is... Figure 10 The location shown.
[0133] Specifically, with Figure 10 As shown, when the first pushing member 510 leaves the limiting member 140 and the pawl member 300 is in the second position, the first pushing member 510 will rotate clockwise and press against the limiting block 420 of the driving member 400, thereby the first pushing member 510 can be stably held in the second pushing position.
[0134] In this disclosure, the first pushing component 510 is provided with a limiting protrusion 513, and the second pushing component 520 includes a first pushing arm 522. The first pushing arm 522 cooperates with the limiting protrusion 513 of the first pushing component 510 so that the first pushing component 510 and the second pushing component 520 are in close contact.
[0135] Specifically, a fourth spring 900 is sleeved on the shaft component. One end of the fourth spring 900 stops at the first push arm 522, and the other end of the fourth spring 900 stops at the drive component 400, for example, at the limiting block 420 of the drive component 400. At this time, the other end of the fourth spring 900 and the first push component 510 are respectively located on both sides of the limiting block 420.
[0136] The second pushing component 520 includes a second pushing arm 523; when the first pushing arm 522 is in the second pushing position, the second pushing arm 523 can push the pawl component 300. Preferably, the reaction force applied by the pawl component 300 to the second pushing component 520 can cause the second pushing component 520 to rotate clockwise. At this time, the first pushing arm 522 of the second pushing component 520 can apply an external force to the limiting protrusion 513, and cause the first pushing component 510 to also have a clockwise movement tendency. Thus, the first pushing component 510 can fit more tightly against the limiting block 420 without disengaging from the limiting block 420.
[0137] The portion of the second push arm 523 that contacts the pawl member 300 extends beyond the first push member 510. In other words, 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 during the second drive.
[0138] Overall, when the pawl component 300 is in the first position, the drive component 400 moves from the initial position to the drive position, and the pawl component 300 can be pushed to the second position by the first push component 510; when the pawl component 300 is in the second position, the drive component 400 moves from the initial position to the drive position, and the pawl component 300 is pushed to the third position away from the second position by the second push component 520, and when the pawl component 300 is in the third position, the latch component 200 is released, thereby realizing the double pull unlocking of the front cover lock.
[0139] The front cover lock disclosed herein may further include: a latch position switch 150, which is triggered by the latch component 200 when the latch component 200 is in the first locking position.
[0140] According to another aspect of this disclosure, a motor vehicle is provided, which includes the aforementioned hood lock.
