Description

Technical Field

[0001] The present invention relates to the technical field of vehicle locks, and in particular to a hood lock and a vehicle. Background Art

[0002] Due to traffic regulations in different countries, vehicles are divided into left-hand drive and right-hand drive vehicles. When designing engine hood locks, differentiated designs are required for markets with different driving habits. Left-hand and right-hand drive vehicles cannot use the same hood lock, which undoubtedly increases the difficulty of common parts.

[0003] At the same time, in the field of after-sales maintenance, the situation that the opening cable fails due to vehicle collision or natural aging often occurs. Therefore, it is particularly important to reserve a backup opening mechanism, but the hood lock of the related art lacks a backup opening mechanism. Summary of the Invention

[0004] In view of this, the present invention provides a hood lock and a vehicle to solve the problem that left-hand and right-hand drive vehicles cannot use the same hood lock and that traditional hood locks lack a backup opening mechanism.

[0005] In a first aspect, the present invention provides a hood lock, comprising:

[0006] The lock housing is provided with a first pin shaft and a second pin shaft;

[0007] A lock hook, adapted to rotate about the first pin shaft to switch between a locked state and an unlocked state, the lock hook having a locking portion;

[0008] The stop plate is adapted to rotate about the second pin shaft to switch between a first state and a second state, and the stop plate has a limiting portion; the limiting portion is adapted to abut against the locking portion in the first state to maintain the lock hook in the locked state; and the limiting portion is further adapted to disengage from the locking portion in the second state to release the restriction on the lock hook;

[0009] A connecting rod assembly, comprising a push rod assembly and a pull rod assembly, and a guide portion for guiding a connection portion between the push rod assembly and the pull rod assembly, wherein the guide portion is adapted to move the connection portion along a preset direction to drive the stop plate to switch between a first state and a second state;

[0010] The push rod assembly and / or the stop plate is provided with a first cable interface, and the pull rod assembly is provided with a second cable interface; at least one of the first cable interface and the second cable interface is suitable for connecting with the cable.

[0011] Beneficial Effects: The hood lock provided by the embodiment of the present invention provides a connecting rod assembly, wherein the guide portion is adapted to move the connecting portion in a preset direction, so that the push rod group and the pull rod group are constrained by the guide portion and thus move along a preset movable path. Furthermore, by providing a first cable interface and a second cable interface, at least one of which is adapted to be connected to a cable, the hood lock can be unlocked in both directions, thereby accommodating the cable arrangement for both left-hand drive and right-hand drive vehicles, improving the degree of component commonality, and reducing development costs. The cable can include a first cable and a second cable, the first cable being connected to the first cable interface and the second cable being connected to the second cable interface. Furthermore, depending on the actual installation requirements of left-hand drive and right-hand drive vehicles, one of the first cable and the second cable can serve as the main cable, and the other as a backup opening cable, providing a backup opening possibility in the event of failure of the main cable. This improves maintenance convenience and reduces the occurrence of increased after-sales repair costs due to damage to parts caused by an inability to open the hood.

[0012] In an optional embodiment, the pull rod group includes a pull rod, the push rod group includes a push rod, the connecting part includes a first hinge shaft, and the guide part includes a guide groove; the pull rod and the push rod are hingedly connected via the first hinge shaft, and the first hinge shaft is at least partially slidably arranged in the guide groove.

[0013] In an optional embodiment, one end of the push rod away from the first hinge axis is hingedly connected to the stop plate via a second hinge axis.

[0014] In an optional embodiment, the second cable interface is provided at an end of the pull rod away from the first hinge axis; the cable includes a second cable, and the second cable is connected to the second cable interface.

[0015] Beneficial effect: A second cable interface is provided at one end of the pull rod away from the first hinge axis. By connecting the second cable to the second cable interface, the second cable can be pulled to drive the pull rod to move. Since the pull rod and the push rod are hingedly connected via the first hinge axis, and since the first hinge axis is slidably arranged in the guide groove, the pull of the second cable causes the end of the pull rod connected to the first hinge axis to drive the end of the push rod connected to the first hinge axis to move, and the movement path is the same as the extension direction of the guide groove. Since the stop plate is hinged to the second pin shaft, the stop plate can rotate relative to the second pin shaft under the push of the push rod. As the stop plate rotates, the limit portion and the locking portion can be disengaged to release the restriction on the lock hook, so that the lock hook can switch from the locked state to the unlocked state.

[0016] In an optional embodiment, the first cable interface is provided at an end of the push rod away from the first hinge axis, and / or the first cable interface is provided at the stop plate;

[0017] The cable includes a first cable connected to a first cable interface.

[0018] Beneficial Effect: The first cable interface is provided on the stop plate, and the first cable is connected to the first cable interface. Since the first cable and the second cable move in opposite directions, when the first cable is pulled, the stop plate can be driven to rotate counterclockwise around the second pin. As the stop plate rotates, the limit portion and the locking portion can be disengaged, thereby releasing the restriction on the lock hook, allowing the lock hook to switch from a locked state to an unlocked state.

[0019] In an optional embodiment, the hood lock further comprises: a first torsion spring connected to the lock hook and adapted to provide a reset force for the lock hook to maintain the lock hook in an unlocked state.

[0020] Beneficial effect: Since the first torsion spring is suitable for providing a reset force for the lock hook to maintain it in the unlocked state, when the lock hook is in the locked state, the first torsion spring is always in a compressed state. When the limiting portion of the stop plate is disengaged from the locking portion of the lock hook, the restriction on the lock hook can be released, and then under the action of the reset force of the first torsion spring, the lock hook is rotated to the unlocked state, thereby facilitating the disengagement of the lock rod.

[0021] In an optional embodiment, the hood lock further includes: a second torsion spring connected to the stop plate and adapted to provide a reset force for the stop plate to maintain the stop plate in the first state.

[0022] Advantageous Effect: Because the second torsion spring provides a restoring force to maintain the stop plate in the first state, pulling the first or second cable overcomes the elastic force of the second torsion spring. When the pulling force of the first or second cable disappears, the restoring force of the second torsion spring causes the stop plate to return to the first state.

[0023] In an optional embodiment, the bisector of the angle between the pull rod and the push rod is parallel to the extension direction of the guide groove.

[0024] Beneficial effect: This ensures that the force transmission effect from the pull rod to the push rod is maximized, and enables the first hinge shaft to move more smoothly along the guide groove.

[0025] In an optional embodiment, the first hinge shaft moves from the first end to the second end of the guide groove, and the angle between the pull rod and the push rod gradually increases; and when the first hinge shaft is located at the second end of the guide groove, the angle between the pull rod and the push rod is less than 180°.

[0026] Beneficial effect: When the first hinge shaft is located at the second end of the guide groove, the self-locking phenomenon is avoided by limiting the angle between the pull rod and the push rod to less than 180°. Under the action of the reset force of the second torsion spring, the first hinge shaft can be smoothly reset from the second end of the guide groove to the first end, and the stop plate returns to the position of the first state again.

[0027] In an optional embodiment, the lock housing is provided with a lock rod groove, which is adapted to guide the movement of the lock rod;

[0028] The lock hook is provided with a lock slot;

[0029] When the lock hook is in the locked state, along the axial direction of the first pin shaft, the lock groove and the lock rod groove at least partially overlap to form a locking cavity, and the lock rod is located in the locking cavity.

[0030] In an optional embodiment, the first hinge shaft moves from the first end of the guide groove to the second end, so that the push rod pushes the stop plate to rotate around the second pin shaft in the first direction, so that the stop plate switches from the first state to the second state.

[0031] In a second aspect, the present invention further provides a vehicle, comprising: a vehicle body, and the hood lock as described above, which is arranged on the vehicle body.

[0032] In an optional embodiment, the vehicle includes a left-hand drive vehicle or a right-hand drive vehicle.

[0033] Beneficial Effects: The vehicle provided by the embodiments of the present invention utilizes a first cable and a second cable, one of which is connected to the connecting rod assembly and the other to the connecting rod assembly and / or the stop plate, thereby achieving bidirectional unlocking of the hood lock. This arrangement accommodates both left-hand drive and right-hand drive vehicles, improves component commonality, and reduces development costs. Furthermore, depending on the actual installation requirements of left-hand drive and right-hand drive vehicles, one of the first cable and the second cable can serve as the primary cable, while the other can serve as a backup cable. This provides a backup opening mechanism in the event of a primary cable failure, improving maintenance convenience and reducing the risk of increased after-sales repair costs due to component damage caused by an inability to open the hood.

[0050] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0051] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0053] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] With the accelerated globalization of my country's automotive industry, an increasing number of vehicles are being exported to overseas markets. Vehicles are now classified as left-hand drive or right-hand drive vehicles, depending on the traffic regulations of different countries. The engine hood lock typically requires a hood cable to open, and the hood cable's handle is often located on the driver's side, requiring adjustments to suit left-hand and right-hand drive vehicles. Consequently, the design of the engine hood lock requires differentiation for markets with different driving habits. Due to the different cable pull directions, left-hand and right-hand drive vehicles often cannot use the same hood lock, which undoubtedly increases the difficulty of standardizing parts and increases development costs.

[0055] Furthermore, in the aftermarket repair industry, failure of the opening cable due to vehicle collisions or natural aging often occurs, rendering the hood handle inoperable. Traditional solutions sometimes require damaging surrounding components. Once the lock body is accessible, the hood lock is manually pried open with specialized tools. This method is cumbersome and difficult to open without specialized tools. Therefore, it is crucial to have a backup opening mechanism to reduce the difficulty of unlocking and minimize the need for specialized tools.

[0056] The following combination Figures 1 to 8 , describing embodiments of the present invention.

[0057] According to an embodiment of the present invention, in one aspect, a hood lock is provided, comprising:

[0058] Lock case 1;

[0059] The lock hook 2 is adapted to rotate about a first pin 22 to switch between a locked state and an unlocked state, and the lock hook 2 has a locking portion 21;

[0060] The stop plate 3 is adapted to rotate about the second pin 32 to switch between a first state and a second state. The stop plate 3 has a limiting portion 31. The limiting portion 31 is adapted to abut against the locking portion 21 in the first state to maintain the lock hook 2 in the locked state. The limiting portion 31 is also adapted to disengage from the locking portion 21 in the second state to release the restriction on the lock hook 2.

[0061] The connecting rod assembly 4 includes a push rod group and a pull rod group, and a guide portion for guiding the connection portion between the push rod group and the pull rod group, the guide portion being adapted to move the connection portion along a preset direction to drive the stop plate 3 to switch between the first state and the second state;

[0062] The push rod assembly and / or the stop plate 3 is provided with a first cable interface 33 , and the pull rod assembly is provided with a second cable interface 44 ; at least one of the first cable interface 33 and the second cable interface 44 is suitable for connecting with a cable.

[0063] The lock hook 2 of this embodiment is used to limit the lock rod 8 in the locked state, and the lock rod 8 is connected to the hood of the vehicle, that is, the hood is locked. The lock hook 2 can release the limit on the lock rod 8 in the unlocked state, thereby facilitating the opening of the hood.

[0064] The lock housing 1 serves as the outer shell of the hood lock, and all structural components are suitable for being installed inside the lock housing 1 .

[0065] By installing the first pin 22 on the lock housing 1, the lock hook 2 can be ensured to rotate around the first pin 22, thereby achieving movement of the lock hook 2 relative to the lock housing 1. Similarly, by installing the second pin 32 on the lock housing 1, the stop plate 3 can be ensured to rotate around the second pin 32, thereby achieving movement of the stop plate 3 relative to the lock housing 1.

[0066] In this embodiment, the guide portion may be a guide groove 15 formed in the lock housing 1 or a plurality of guide posts formed inside the lock housing 1 , which enclose a guide space suitable for guiding the connecting portion.

[0067] The limiting portion 31 of the stop plate 3 and the locking portion 21 of the lock hook 2 are adapted to abut and cooperate with each other. When the stop plate 3 is in the first state, the limiting portion 31 abuts against the locking portion 21 to maintain the lock hook 2 in the locked state. At this time, the lock hook 2 cannot be disengaged from the locking portion 21 when subjected to an external force, thereby ensuring that the lock hook 2 remains in the locked state. Only when the stop plate 3 rotates, causing the stop plate 3 to switch from the first state to the second state, can the limiting portion 31 be disengaged from the locking portion 21, and the limiting portion 31 will release the restriction on the locking portion 21, thereby releasing the restriction on the lock hook 2, allowing the lock hook 2 to switch from the locked state to the unlocked state.

[0068] The rotation of the stop plate 3 about the second pin 32 can be achieved by pulling a cable. In this embodiment, the cable may specifically include a first cable 51 and a second cable 52, wherein the first cable 51 is connected to the first cable interface 33, and the second cable 52 is connected to the second cable interface 44. Because the cable directions differ between left-hand drive and right-hand drive vehicles, to facilitate universal application of both left-hand and right-hand drive vehicles, this embodiment employs a connecting rod assembly 4, such that one of the first and second cables 51, 52 is connected to the connecting rod assembly 4, while the other is connected to the connecting rod assembly 4 and / or the stop plate 3. This facilitates pulling from two directions, facilitating universal application of both left-hand and right-hand drive vehicles.

[0069] Among them, according to the actual installation requirements of left-hand drive vehicles and right-hand drive vehicles, one of the first cable 51 and the second cable 52 can be used as the main cable, and extended into the cab, and connected to the opening handle of the hood cover; the other of the first cable 51 and the second cable 52 can be used as a backup opening cable, and the opening position of the backup opening cable is arranged in a hidden and easily accessible position, so as to provide a backup opening possibility when the main cable fails, thereby reducing the occurrence of increased after-sales maintenance costs due to damage to parts caused by the inability to open the hood.

[0070] In this embodiment, since the lock housing 1 is formed with a guide groove 15, the connecting rod assembly 4 is suitable for sliding relative to the guide groove 15, so that the connecting rod assembly 4 is constrained by the guide groove 15 and then moves along a preset active path. When the connecting rod assembly 4 is actuated, it can drive the stop plate 3 to switch between the first state and the second state.

[0071] Specifically in this embodiment, the first cable 51 is connected to the connecting rod assembly 4 , and the second cable 52 is connected to the stop plate 3 .

[0072] The hood lock provided by an embodiment of the present invention comprises a connecting rod assembly 4 adapted to slide relative to a guide groove 15, constrained by the guide groove 15 and thereby moving along a predetermined path. Furthermore, a first cable interface 33 is provided on the push rod assembly and / or the stop plate 3, and a second cable interface 44 is provided on the pull rod assembly. Alternatively, a first cable 51 can be connected to the first cable interface 33, or a second cable 52 can be connected to the second cable interface 44, as required. This allows for bidirectional unlocking of the hood lock, accommodating both left-hand drive and right-hand drive vehicle cable layouts, improving component commonality, and reducing development costs. Furthermore, depending on the actual installation requirements of left-hand drive and right-hand drive vehicles, one of the first cable 51 and the second cable 52 can serve as the primary release cable, while the other can serve as a backup release cable. This provides a backup release mechanism in the event of a primary cable failure, improving maintenance convenience and reducing the risk of component damage and increased after-sales repair costs due to an inability to open the hood.

[0073] In addition, the hood lock of this embodiment is driven by a connecting rod connected by a pin shaft, and the implementation principle of two-way unlocking is different. Therefore, the pulling action of the first cable 51 and the second cable 52 does not require the provision of a reverse driving member as an intermediate force transmission structure. Since there is no need to provide a reverse driving member, the wear caused by the relative movement between the reverse driving members is reduced, the structural design is relatively simple, and the number of parts is smaller.

[0074] like Figure 1 As shown, the lock housing 1 is provided with a lock housing fixing hole 13. The lock housing 1 can be fixed to the vehicle body by inserting a bolt into the lock housing fixing hole 13. The lock housing 1 is provided with a first lock sleeve connecting position 11 and a second lock sleeve connecting position 12. The first cable 51 and the second cable 52 are respectively installed in the first lock sleeve connecting position 11 and the second lock sleeve connecting position 12, thereby achieving a clamping connection between the first cable 51 and the second cable 52 to prevent them from falling off.

[0075] The first cable 51 and the second cable 52 may be collectively referred to as cables 5 .

[0076] In some embodiments, combined Figure 2 、 Figure 4 As shown, the pull rod group includes a pull rod 41, the push rod group includes a push rod 43, the connecting portion includes a first hinge shaft 42, and the guide portion includes a guide groove 15; the pull rod 41 and the push rod 43 are hingedly connected via the first hinge shaft 42, and the first hinge shaft 42 is at least partially slidably disposed in the guide groove 15;

[0077] One end of the push rod 43 away from the first hinge shaft 42 is hingedly connected to the stop plate 3 via the second hinge shaft 45 .

[0078] In some embodiments, the second cable interface 44 is disposed at an end of the pull rod 41 away from the first hinge shaft 42 , and the second cable 52 is connected to the second cable interface 44 .

[0079] In this embodiment, the guide groove 15 is provided on the lock housing 1 , and specifically, the setting direction of the guide groove 15 may be perpendicular to the pulling direction of the cable 5 .

[0080] A second cable interface 44 is provided at one end of the pull rod 41 away from the first hinge shaft 42. By connecting the second cable 52 to the second cable interface 44, the second cable 52 can be pulled to drive the pull rod 41 to move. Since the pull rod 41 and the push rod 43 are hingedly connected via the first hinge shaft 42, and since the first hinge shaft 42 is slidingly arranged in the guide groove 15, under the pulling of the second cable 52, the end of the pull rod 41 connected to the first hinge shaft 42 drives the end of the push rod 43 connected to the first hinge shaft 42 to move, and the moving path is the same as the extension direction of the guide groove 15; for example, in this embodiment, it can move from the first end of the guide groove 15 to the second end.

[0081] Since the stop plate 3 is hinged to the second pin 32, the stop plate 3 can rotate relative to the second pin 32 under the pushing action of the push rod 43. Figures 6 and 7 During the change process, the stop plate 3 rotates counterclockwise around the second pin shaft 32. As the stop plate 3 rotates, the limiting portion 31 can be disengaged from the locking portion 21 to release the restriction on the lock hook 2, so that the lock hook 2 switches from the locked state to the unlocked state.

[0082] Figure 6 This is a schematic diagram showing the hood lock in a locked state, where the first hinge shaft 42 is located at the first end of the guide slot 15 . Figure 7 FIG. 4 is a schematic diagram of the hood lock in the unlocking process, at which the first hinge shaft 42 moves from the first end to the second end of the guide groove 15 . Figure 8 1 is a schematic diagram of the hood lock in the unlocked state, at which time the first hinge shaft 42 is reset from the second end to the first end of the guide groove 15. The reset of the first hinge shaft 42 relies on the reset force of the torsion spring of the stop plate 3.

[0083] In this embodiment, when the hood lock is in the installed state, the guide slot 15 can extend in a vertical direction, wherein the first end of the guide slot 15 can be the upper end in the vertical direction, and the second end of the guide slot 15 can be the lower end in the vertical direction. When the second cable 52 is pulled, the pull rod 41 drives the first hinge shaft 42 to move vertically downward, which in turn drives the push rod 43 to move laterally with the second hinge shaft 45 connected to the stop plate 3, pushing the stop plate 3 to rotate, thereby achieving unlocking.

[0084] In some embodiments, combined Figure 3As shown, the first cable interface 33 is provided at one end of the push rod 43 away from the first hinge shaft 42 , and / or the first cable interface 33 is provided on the stop plate 3 , and the first cable 51 is connected to the first cable interface 33 .

[0085] In this embodiment, the first cable interface 33 is provided on the stop plate 3, and the first cable 51 is connected to the first cable interface 33. Since the moving directions of the first cable 51 and the second cable 52 are opposite, when the first cable 51 is pulled, the first cable 51 is connected to the stop plate 3. Figures 6 and 7 The changing process can drive the stop plate 3 to rotate counterclockwise around the second pin shaft 32. As the stop plate 3 rotates, the limiting portion 31 can be disengaged from the locking portion 21 to release the restriction on the lock hook 2, so that the lock hook 2 is switched from the locked state to the unlocked state.

[0086] Pulling the first cable 51 can directly drive the stop plate 3 to rotate and unlock; pulling the second cable 52 converts the pulling force into a thrust in the opposite direction through the mechanical transmission of the connecting rod assembly 4, thereby driving the stop plate 3 to rotate and unlock.

[0087] Although the first and second cables 51, 52 move in opposite directions, they both achieve the same unlocking function. Therefore, depending on the actual installation requirements of left-hand drive or right-hand drive vehicles, one of the first and second cables 51, 52 can serve as the primary cable, while the other can serve as a backup opening cable. This provides a backup opening mechanism in the event of a primary cable failure, improving maintenance convenience and reducing the risk of component damage and increased after-sales repair costs caused by an inability to open the hood. Furthermore, both the first and second cables 51, 52 can be directly pulled to unlock the hood, eliminating the need for a reverse drive as an intermediate force transmission mechanism.

[0088] In some embodiments, combined Figure 5 As shown, the hood lock further includes: a first torsion spring 6, which is connected to the lock hook 2 and is suitable for providing a reset force for the lock hook 2 to maintain it in the unlocked state;

[0089] And / or, the hood lock further includes: a second torsion spring 7 , the second torsion spring 7 is connected to the stop plate 3 , and is adapted to provide a restoring force for the stop plate 3 to maintain the stop plate 3 in the first state.

[0090] Since the first torsion spring 6 is suitable for providing a reset force for the lock hook 2 to maintain it in the unlocked state, when the lock hook 2 is in the locked state, the first torsion spring 6 is always in a compressed state. When the limiting portion 31 of the stop plate 3 is disengaged from the locking portion 21 of the lock hook 2, the restriction on the lock hook 2 can be released, and then under the action of the reset force of the first torsion spring 6, the lock hook 2 is rotated to the unlocked state, thereby facilitating the disengagement of the lock rod 8.

[0091] Because the second torsion spring 7 is adapted to provide a restoring force for the stop plate 3 to maintain the first state, when the first cable 51 or the second cable 52 is pulled, the elastic force of the second torsion spring 7 must be overcome. When the pulling force of the first cable 51 or the second cable 52 disappears, the stop plate 3 returns to the first state under the restoring force of the second torsion spring 7.

[0092] In addition, combined Figure 6 As shown, when the lock hook 2 is in the locked state, under the action of the restoring force of the first torsion spring 6, the locking portion 21 of the lock hook 2 will apply a force to the limiting portion 31 of the stop plate 3, but because the first hinge shaft 42 is pressed against the first end of the guide groove 15, the stop plate 3 cannot rotate clockwise; or, due to the tension of the first cable 51, the stop plate 3 cannot rotate clockwise; and thus the lock hook 2 cannot escape freely, thereby ensuring the reliability of the lock hook 2 when it is in the locked state.

[0093] In this embodiment, the lock housing 1 is fixedly mounted on the vehicle body, the lock hook 2 is fixedly connected to the housing via a first pin 22, and the first torsion spring 6 is sleeved around the first pin 22 and engaged with the lock hook 2. Under the action of an external force, typically when the hood is closed downward, the downward pressure exerted by the lock rod 8 on the lock hook 2 causes the lock hook 2 to rotate about the first pin 22, causing the locking portion 21 to press against the limiting portion 31 of the stop plate 3, and the locking portion 21 to move from above the limiting portion 31 to below the limiting portion 31, thereby achieving locking.

[0094] In some embodiments, the bisector of the angle between the pull rod 41 and the push rod 43 is parallel to the extension direction of the guide slot 15 , thereby ensuring that the force transmission effect of the pull rod 41 to the push rod 43 is maximized and enabling the first hinge shaft 42 to move along the guide slot 15 more smoothly.

[0095] In some embodiments, the connecting line between the first pin shaft 22 and the second pin shaft 32 is perpendicular to the extending direction of the guide groove 15 .

[0096] In some embodiments, combined Figure 7 As shown, the first hinge shaft 42 moves from the first end to the second end of the guide groove 15, and the angle between the pull rod 41 and the push rod 43 gradually increases; and when the first hinge shaft 42 is located at the second end of the guide groove 15, the angle between the pull rod 41 and the push rod 43 is less than 180°.

[0097] When the first hinge shaft 42 is located at the second end of the guide groove 15, the self-locking phenomenon is avoided by limiting the angle between the pull rod 41 and the push rod 43 to be less than 180°. Under the action of the reset force of the second torsion spring 7, the first hinge shaft 42 is ensured to be able to smoothly reset from the second end of the guide groove 15 to the first end, and the stop plate 3 returns to the position of the first state again.

[0098] In some embodiments, combined Figure 3 As shown, the lock housing 1 is provided with a lock rod groove 14, which is suitable for guiding the movement of the lock rod 8;

[0099] The lock hook 2 is provided with a lock slot 23;

[0100] When the lock hook 2 is in the locked state, along the axial direction of the first pin shaft 22 , the lock groove 23 and the lock rod groove 14 at least partially overlap to form a locking cavity, and the lock rod 8 is located in the locking cavity.

[0101] Figure 3 The movement path of the locking bar 8 is shown.

[0102] The locking principle of the lock bar 8 in this embodiment is as follows: the lock hook 2 is provided with a locking portion 21, which extends into the lock bar slot 14. Therefore, when the lock bar 8 moves along the movement path, it can strike the locking portion 21, thereby driving the lock hook 2 to rotate. When the lock hook 2 rotates in the locking direction, it presses the limit portion 31, thereby driving the stop plate 3 to rotate. When the lock hook 2 is in the locked position, the locking portion 21 is clamped by the limit portion 31 of the stop plate 3, maintaining the locked position. At this time, the opening direction of the lock slot 23 is opposite to the opening direction of the lock bar slot 14. The lock bar 8 is located in the locking cavity and cannot escape on its own.

[0103] The unlocking principle of the locking rod 8 in this embodiment is as follows: the cable 5 drives the stop plate 3 to rotate, which can disengage the limiting portion 31 from the locking portion 21 to release the restriction on the lock hook 2, so that the lock hook 2 can switch from the locked state to the unlocked state; at this time, the opening direction of the lock groove 23 and the opening direction of the lock rod groove 14 are both upward, and the lock rod 8 can disengage along the lock rod groove 14.

[0104] In some embodiments, the first hinge shaft 42 moves from the first end of the guide groove 15 to the second end, so that the push rod 43 pushes the stop plate 3 to rotate along the first direction around the second pin shaft 32, so that the stop plate 3 switches from the first state to the second state.

[0105] Whether the vehicle is a left-hand drive model or a right-hand drive model, the locking principle is the same and will not be repeated here.

[0106] Combine Figure 6 As shown in the figure, when the vehicle is a left-hand drive model, the unlocking principle is as follows:

[0107] When the first cable 51 is pulled, Figures 6 and 7 The changing process can drive the stop plate 3 to rotate counterclockwise around the second pin shaft 32. As the stop plate 3 rotates, the limiting portion 31 is disengaged from the locking portion 21 to release the restriction on the lock hook 2. The lock hook 2 is switched from the locked state to the unlocked state under the reset force of the first torsion spring 6.

[0108] Combine Figure 6As shown in the figure, when the vehicle is a right-hand drive model, the unlocking principle is as follows:

[0109] Pull the second cable 52, and then drive the pull rod 41 to move. Since the pull rod 41 and the push rod 43 are hingedly connected via the first hinge shaft 42, and since the first hinge shaft 42 is slidably arranged in the guide groove 15, the second cable 52 pulls, so that the end of the pull rod 41 connected to the first hinge shaft 42 drives the end of the push rod 43 connected to the first hinge shaft 42 to move, and the moving path is the same as the extension direction of the guide groove 15; since the stop plate 3 is hinged to the second pin shaft 32, under the push of the push rod 43, the stop plate 3 can rotate relative to the second pin shaft 32. Figures 6 and 7 During the change process, the stop plate 3 rotates counterclockwise around the second pin shaft 32. As the stop plate 3 rotates, the limiting portion 31 can be disengaged from the locking portion 21 to release the restriction on the lock hook 2. The lock hook 2 is switched from the locked state to the unlocked state under the reset force of the first torsion spring 6.

[0110] After the main cable is arranged for left-hand drive or right-hand drive vehicles, one end of the cable interface is vacant. The vacant cable interface can be used to arrange a spare opening cable to provide a backup opening possibility when the main cable fails.

[0111] According to another aspect of an embodiment of the present invention, a vehicle is provided, including: a vehicle body, and the hood lock as described above, which is arranged on the vehicle body.

[0112] In some embodiments, the vehicle comprises a left-hand drive vehicle or a right-hand drive vehicle.

[0113] The vehicle provided by the embodiment of the present invention utilizes a first cable 51 and a second cable 52, wherein one of the first cable 51 and the second cable 52 is connected to the connecting rod assembly 4, while the other is connected to the connecting rod assembly 4 and / or the stop plate 3, thereby achieving bidirectional unlocking of the hood lock. This arrangement accommodates both left-hand drive and right-hand drive vehicle cable arrangements, improves component commonality, and reduces development costs. Furthermore, depending on the actual installation requirements of left-hand drive and right-hand drive vehicles, one of the first cable 51 and the second cable 52 can serve as the primary cable, while the other can serve as a backup opening cable. This provides a backup opening mechanism in the event of a primary cable failure, improving maintenance convenience and reducing the risk of increased after-sales repair costs due to component damage caused by an inability to open the hood.

[0114] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present invention.
