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] According to the traffic regulations of different countries, vehicles are divided into left-hand drive and right-hand drive. When designing the engine hood lock, it is necessary to carry out differentiated designs 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 commonality of parts.

[0003] Meanwhile, in the after-sales maintenance field, the failure of the opening cable 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 the traditional hood lock lacks 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 a 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 around the second pin shaft to switch between the first state and the 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; the limiting portion is also adapted to be disengaged from the locking portion in the second state to release the restriction on the lock hook;

[0009] The connecting rod assembly includes a push rod group and a pull rod group, and a guide part for guiding the connection part between the push rod group and the pull rod group, wherein the guide part is suitable for moving the connection part 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 being connected to the cable.

[0011] Beneficial effects: The hood lock provided by the embodiment of the present invention, by setting a connecting rod assembly, the guide part is suitable for moving the connecting part along a preset direction, so that the push rod group and the pull rod group are constrained by the guide part, and then move along the preset active path; and by setting a first cable interface and a second cable interface, at least one of the first cable interface and the second cable interface is suitable for connecting with the cable, so as to facilitate the two-way unlocking of the hood lock, so as to achieve the cable arrangement of both left-hand drive and right-hand drive vehicles, improve the degree of commonality of parts, and reduce development costs. The cable can include a first cable and a second cable, the first cable is connected to the first cable interface, and the second cable is connected to the second cable interface; and according to the actual installation requirements of left-hand drive vehicles and right-hand drive vehicles, one of the first cable and the second cable can be used as a main cable, and the other can be used as a backup opening cable, so as to provide a backup opening possibility when the main cable fails, thereby improving the maintenance convenience and reducing the occurrence of increased after-sales maintenance costs caused by damage to parts due to the 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 axis, and the guide part includes a guide groove; the pull rod and the push rod are hingedly connected via the first hinge axis, and the first hinge axis is at least partially slidably disposed 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 arranged 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 shaft. 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 shaft, and since the first hinge shaft is slidably arranged in the guide groove, under the pulling of the second cable, the end of the pull rod connected to the first hinge shaft drives the end of the push rod connected to the first hinge shaft to move, and the moving path is the same as the extension direction of the guide groove. Since the stop plate is hinged to the second pin shaft, under the pushing action of the push rod, the stop plate can rotate relative to the second pin shaft. With the rotation of the stop plate, the limit part and the locking part 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 arranged at an end of the push rod away from the first hinge axis, and / or the first cable interface is arranged 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 arranged 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 shaft, and as the stop plate rotates, the limiting part and the locking part can be disengaged to release the restriction on the lock hook, so that the lock hook can be switched from the locked state to the unlocked state.

[0019] In an optional embodiment, the hood lock further comprises: a first torsion spring, the first torsion spring is connected to the lock hook and is suitable for providing 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 an unlocked state, when the lock hook is in a 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 removal of the lock rod.

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

[0022] Beneficial effect: Since the second torsion spring is suitable for providing a restoring force for the stop plate to maintain the first state, when the first cable or the second cable is pulled, the elastic force of the second torsion spring needs to be overcome. When the pulling force of the first cable or the second cable disappears, the stop plate will return to the position of the first state again under the action of the restoring force of the second torsion spring.

[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 along the guide groove more smoothly.

[0025] In an optional embodiment, the first hinge axis 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 axis 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 be 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, and the lock rod groove is suitable for guiding the movement of the lock rod;

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

[0029] When the lock hook is in a 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 a 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 embodiment of the present invention realizes two-way unlocking of the hood lock by setting a first cable and a second cable, so that one of the first cable and the second cable is connected to the connecting rod assembly, and the other is connected to the connecting rod assembly and / or the stop plate, thereby achieving the cable arrangement of both left-hand drive and right-hand drive vehicles, improving the degree of commonality of parts, and reducing development costs. In addition, according to the actual installation requirements of left-hand drive vehicles and right-hand drive vehicles, one of the first cable and the second cable can be used as the main cable, and the other can be used as a backup opening cable, so as to provide a backup opening possibility when the main cable fails, thereby improving the convenience of maintenance and reducing the occurrence of increased after-sales maintenance costs caused by damage to parts due to the inability to open the hood.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the 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 creative work are 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", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to 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] As the globalization of my country's automobile industry accelerates, more and more vehicles need to be exported to overseas markets. According to the traffic rules and regulations of different countries, vehicles are also divided into left-hand drive vehicles and right-hand drive vehicles. The engine hood lock usually needs to be pulled open by the hood cable, and the opening handle of the hood cable is often set on the driver's side, so the direction needs to be adjusted according to the difference between left-hand drive and right-hand drive vehicles. Therefore, when designing the engine hood lock, it is necessary to carry out differentiated designs for markets with different driving habits. Due to the different pulling wire directions, left-hand and right-hand drive models often cannot use the same hood lock, which undoubtedly increases the difficulty of generalization of parts and increases development costs.

[0055] At the same time, in the field of after-sales maintenance, the opening wire often fails due to vehicle collision or natural aging, resulting in the inability to open the hood through the handle. Traditional solutions sometimes require the destruction of peripheral parts. After the lock body is accessible, the lock body is manually pried directly with special tools to open the hood lock. This operation method is relatively cumbersome, and it is difficult to open the hood lock when special tools are missing. For this reason, it is particularly important to reserve a backup opening mechanism, reduce the difficulty of unlocking, and reduce the use of special tools.

[0056] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

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

[0058] Lock housing 1;

[0059] The lock hook 2 is adapted to rotate around a first pin shaft 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 around the second pin shaft 32 to switch between the first state and the second state, and 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 be disengaged 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, wherein the guide portion is suitable for moving 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 each structural component is suitable for being installed inside the lock housing 1 .

[0065] By installing the first pin shaft 22 on the lock housing 1, it is possible to ensure that the lock hook 2 rotates around the first pin shaft 22, so that the lock hook 2 moves relative to the lock housing 1. Similarly, by installing the second pin shaft 32 on the lock housing 1, it is possible to ensure that the stop plate 3 rotates around the second pin shaft 32, so that the stop plate 3 moves 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 may be a plurality of guide columns formed inside the lock housing 1, wherein the plurality of guide columns 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 against 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, so as to ensure that the lock hook 2 is in the locked state. Only when the stop plate 3 rotates, so that the stop plate 3 switches 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, and then release the restriction on the lock hook 2, so that the lock hook 2 switches from the locked state to the unlocked state.

[0068] The rotation of the stop plate 3 around the second pin 32 can be achieved by pulling the cable. In this embodiment, the cable can 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. Since the cable directions of left-hand drive vehicles and right-hand drive vehicles are different, in order to facilitate the commonality of left-hand drive vehicles and right-hand drive vehicles, this embodiment provides a connecting rod assembly 4, so that one of the first cable 51 and the second cable 52 is connected to the connecting rod assembly 4, and the other is connected to the connecting rod assembly 4 and / or the stop plate 3. This facilitates pulling from two directions, and facilitates the commonality of left-hand drive vehicles 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 increase in after-sales maintenance costs caused by damage to parts due to 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 the embodiment of the present invention is provided with a connecting rod assembly 4, which 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 the preset active path; and a first cable interface 33 is provided on the push rod group and / or the stop plate 3, and a second cable interface 44 is provided on the pull rod group, and a first cable 51 can be provided to be connected with the first cable interface 33 as required, and a second cable 52 can also be provided to be connected with the second cable interface 44. Thus, the hood lock can be unlocked in both directions, and the cable arrangement of both left-hand drive and right-hand drive vehicles can be taken into account, the degree of commonality of parts can be improved, and the development cost can be reduced. And 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 the other can be used as a spare opening cable, so as to provide a spare opening possibility when the main cable fails, thereby improving the maintenance convenience and reducing the occurrence of the situation where the damage of parts caused by the inability to open the hood leads to an increase in after-sales maintenance costs.

[0073] In addition, the hood lock of the present embodiment is driven by a connecting rod connected by a pin shaft, and the implementation principle of the 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 component as an intermediate force transmission structure. Since there is no need to provide a reverse driving component, the wear caused by the relative movement between the reverse driving components 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, and 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, and the first cable 51 and the second cable 52 are respectively installed at the first lock sleeve connecting position 11 and the second lock sleeve connecting position 12, so as to realize the clamping connection of 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, in combination 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 disposed 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 with 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 slidably 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 shaft 32, the stop plate 3 can rotate relative to the second pin shaft 32 under the pushing action of the push rod 43. Figure 6 to Figure 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 It is a schematic diagram showing that the hood lock is in a locked state, at which time the first hinge shaft 42 is located at the first end of the guide groove 15 . Figure 7 It is a schematic diagram of the hood lock in the unlocking process, at which time the first hinge shaft 42 moves from the first end of the guide groove 15 to the second end. Figure 8 1 is a schematic diagram of the hood lock being in an unlocked state, at which 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 installation state, the extension direction of the guide groove 15 can be the vertical direction, wherein the first end of the guide groove 15 can be the upper end in the vertical direction, and the second end of the guide groove 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, thereby driving the second hinge shaft 45 connected to the push rod 43 and the stop plate 3 to move horizontally, pushing the stop plate 3 to rotate, thereby achieving unlocking.

[0084] In some embodiments, in combination Figure 3As shown, the first cable interface 33 is disposed at one end of the push rod 43 away from the first hinge shaft 42 , and / or the first cable interface 33 is disposed 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 arranged 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. Figure 6 to Figure 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 can switch 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 can convert 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 cable 51 and the second cable 52 move in opposite directions, they can achieve the same unlocking function. Therefore, 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 the other can be used as a backup opening cable, so as to provide a backup opening possibility when the main cable fails, thereby improving the maintenance convenience and reducing the occurrence of increased after-sales maintenance costs caused by damage to parts due to the inability to open the hood. In addition, both the first cable 51 and the second cable 52 can be directly pulled to achieve unlocking, and the pulling action does not require the provision of a reverse drive member as an intermediate force transmission structure.

[0088] In some embodiments, in combination 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 an 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 suitable for providing a reset force for the stop plate 3 to maintain the first state.

[0090] Since the first torsion spring 6 is suitable for providing a restoring 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 restoring 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] Since the second torsion spring 7 is suitable for providing 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, it is necessary to overcome the elastic force of the second torsion spring 7. When the pulling force of the first cable 51 or the second cable 52 disappears, the stop plate 3 will return to the position of the first state again under the action of 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 be freely disengaged, 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 automobile body, the lock hook 2 is fixedly connected to the housing through the first pin shaft 22, and the first torsion spring 6 is sleeved on the first pin shaft 22 and connected to the lock hook 2. Under the action of external force, usually when the engine cover is closed downward, the downward pressure of the lock rod 8 on the lock hook 2 can make the lock hook 2 rotate around the first pin shaft 22, so that the locking portion 21 presses the limiting portion 31 of the stop plate 3, and the locking portion 21 moves from the upper side of the limiting portion 31 to the lower side of 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 the first hinge shaft 42 can move along the guide slot 15 more smoothly.

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

[0096] In some embodiments, in combination 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 can be 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, in combination Figure 3 As shown, the lock housing 1 is provided with a lock rod groove 14, and the lock rod groove 14 is suitable for guiding the lock rod 8 to move;

[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 rod 8 in this embodiment is as follows: a locking portion 21 is provided on the lock hook 2, and the locking portion 21 extends into the lock rod groove 14, so that when the lock rod 8 moves along the moving path, it can hit the locking portion 21, thereby driving the lock hook 2 to rotate, and when the lock hook 2 rotates toward the locking direction, it squeezes the limiting portion 31, thereby driving the stop plate 3 to rotate, and when the lock hook 2 is in the locked position, the locking portion 21 is stuck by the limiting portion 31 of the stop plate 3 to maintain the locked position. At this time, the opening direction of the lock groove 23 is opposite to the opening direction of the lock rod groove 14, and the lock rod 8 is located in the locking cavity and cannot escape by itself.

[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, so that the limiting part 31 can be disengaged from the locking part 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 escape 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 described here.

[0106] Combination 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, Figure 6 to Figure 7 The change 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. Under the action of the reset force of the first torsion spring 6, the lock hook 2 switches from the locked state to the unlocked state.

[0108] Combination 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 set 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; because the stop plate 3 is hinged to the second pin shaft 32, under the pushing action of the push rod 43, the stop plate 3 can rotate relative to the second pin shaft 32. Figure 6 to Figure 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. Under the action of the reset force of the first torsion spring 6, the lock hook 2 switches from the locked state to the unlocked state.

[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 an embodiment of the present invention, in another aspect, a vehicle is provided, comprising: a vehicle body, and a hood lock as described above and 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 is provided with a first cable 51 and a second cable 52, so that one of the first cable 51 and the second cable 52 is connected to the connecting rod assembly 4, and the other is connected to the connecting rod assembly 4 and / or the stop plate 3, thereby realizing two-way unlocking of the hood lock, achieving the cable arrangement of both left-hand drive and right-hand drive vehicles, improving the degree of commonality of parts, and reducing development costs. And 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 the other can be used as a backup opening cable, so as to provide a backup opening possibility when the main cable fails, thereby improving the maintenance convenience and reducing the occurrence of increased after-sales maintenance costs caused by damage to parts due to the inability to open the hood.

[0114] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. Although the embodiments of the present invention are described in conjunction with 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 all fall within the scope defined by the present invention.
