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] A toothed driving member is formed with driving teeth, the stop plate is directly or indirectly connected with driven teeth, the driving teeth are meshed with the driven teeth, and the toothed driving member moves to drive the stop plate to switch between a first state and a second state;

[0010] The toothed drive member and / or the stop plate is provided with a first cable interface, and the toothed drive member is provided with a second cable interface, and 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 is provided with a toothed driving member, the active teeth of the toothed driving member are meshed with the driven teeth, so that the toothed driving member moves to drive the stop plate to switch between the first state and the second state; and by providing a first cable interface on the toothed driving member and / or the stop plate, and providing a second cable interface on the toothed driving member, 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 hood lock further comprises: a driven wheel, the driven wheel is fixedly connected to the stop plate, and the driven teeth are formed on the driven wheel;

[0013] The toothed driving member is adapted to rotate around the rotating shaft to drive the driven wheel to rotate synchronously.

[0014] Beneficial effect: Since the driving teeth of the toothed driving member are adapted to the driven teeth of the driven wheel, the toothed driving member always keeps meshing with the driven teeth during the rotation of the toothed driving member around the rotating shaft, thereby driving the driven wheel to rotate synchronously. Since the driven wheel is fixedly connected to the stop plate, the rotation of the toothed driving member can drive the stop plate to rotate, thereby switching the stop plate between the first state and the second state.

[0015] In an optional embodiment, the toothed drive member is coaxially arranged with the first pin shaft, and the locking hook and the toothed drive member rotate independently;

[0016] The driven wheel is coaxially arranged with the second pin shaft, and the stop plate rotates synchronously with the driven wheel.

[0017] Beneficial effect: By arranging the toothed driving member coaxially with the first pin shaft, and arranging the driven wheel coaxially with the second pin shaft, the toothed driving member and the driven wheel can be easily engaged, thereby reducing the difficulty of adapting the toothed driving member and the driven wheel.

[0018] In an optional embodiment, the cable includes 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;

[0019] When the first cable interface is disposed on the toothed driving member, the pulling force direction of the first cable is opposite to the pulling force direction of the second cable, and both do not coincide with the rotation axis of the toothed driving member.

[0020] 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 movement directions of the first cable and the second cable are opposite, 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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;

[0026] Along the axial direction of the first pin shaft, the toothed driving member partially penetrates to form a clearance portion, and the clearance portion is suitable for avoiding the movement of the locking rod.

[0027] Beneficial effect: The toothed driving member partially penetrates to form a clearance portion, and the clearance portion is suitable for avoiding the movement of the locking rod, so that the locking rod will not interfere with the toothed driving member during the movement process.

[0028] In an optional embodiment, 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, the lock rod groove and the yielding portion at least partially overlap to form a locking cavity, and the lock rod is located in the locking cavity.

[0030] 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.

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 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0055] According to an embodiment of the present invention, on the one hand, there is provided a hood lock, comprising:

[0056] The lock housing 1 is provided with a first pin shaft 22 and a second pin shaft 32;

[0057] 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;

[0058] 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;

[0059] The toothed driving member 4 is formed with a driving tooth 41, the stop plate 3 is directly or indirectly connected with a driven tooth 91, the driving tooth 41 is meshed with the driven tooth 91, and the toothed driving member 4 moves to drive the stop plate 3 to switch between the first state and the second state;

[0060] The toothed drive member 4 and / or the stop plate 3 are provided with a first cable interface 33 , and the toothed drive member 4 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.

[0061] 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.

[0062] 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 .

[0063] 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.

[0064] 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.

[0065] 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 toothed drive member 4, so that one of the first cable 51 and the second cable 52 is connected to the toothed drive member 4, and the other is connected to the toothed drive member 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.

[0066] Specifically in this embodiment, the first cable 51 is connected to the toothed driving member 4 , and the second cable 52 is connected to the stop plate 3 .

[0067] 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.

[0068] The hood lock provided by an embodiment of the present invention is provided with a toothed driving member 4, and the active teeth 41 of the toothed driving member 4 are meshed with the driven teeth 91, so that the toothed driving member 4 moves to drive the stop plate 3 to switch between the first state and the second state; and a first cable interface 33 is provided on the toothed driving member 4 and / or the stop plate 3, and a second cable interface 44 is provided on the toothed driving member 4, at least one of the first cable interface 33 and the second cable interface 44 is suitable for connection with the cable to facilitate the two-way unlocking of the hood lock, so as to achieve the cable arrangement that takes into account both left-hand drive and right-hand drive vehicles, improve the degree of commonality of parts, and reduce development costs. The cable may include a first cable 51 and a second cable 52, 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; 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 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 increase in after-sales maintenance costs due to damage to parts caused by the inability to open the hood.

[0069] 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.

[0070] 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.

[0071] The first cable 51 and the second cable 52 may be collectively referred to as cables 5 .

[0072] In some embodiments, in combination Figure 3 As shown, the hood lock further includes: a driven wheel 9, the driven wheel 9 is fixedly connected to the stop plate 3, and a driven tooth 91 is formed on the driven wheel 9;

[0073] The toothed driving member 4 is adapted to rotate around the rotating shaft to drive the driven wheel 9 to rotate synchronously.

[0074] Since the driving teeth 41 of the toothed driving member 4 are adapted to the driven teeth 91 of the driven wheel 9, the toothed driving member 4 always keeps meshing with the driven teeth 91 during the rotation of the toothed driving member 4 around the rotating shaft, thereby driving the driven wheel 9 to rotate synchronously. Since the driven wheel 9 is fixedly connected to the stop plate 3, the rotation of the toothed driving member 4 can drive the stop plate 3 to rotate, thereby switching the stop plate 3 between the first state and the second state.

[0075] As one implementation form, the toothed drive member 4 may be a gear structure. As a modified implementation form, the toothed drive member 4 may also be a rack structure. In this case, the toothed drive member 4 may move along a straight line or along an arc. Regardless of the toothed structure of the toothed drive member 4, as long as the toothed drive member 4 can always be meshed with the driven teeth 91, thereby driving the driven wheel 9 to rotate synchronously, the stop plate 3 can be switched between the first state and the second state.

[0076] In some embodiments, in combination Figure 4 As shown, the toothed drive member 4 is coaxially arranged with the first pin shaft 22, and the lock hook 2 and the toothed drive member 4 rotate independently;

[0077] The driven wheel 9 is coaxially arranged with the second pin shaft 32 , and the stop plate 3 and the driven wheel 9 rotate synchronously.

[0078] By arranging the toothed driving member 4 and the first pin shaft 22 coaxially, and the driven wheel 9 and the second pin shaft 32 coaxially, the toothed driving member 4 and the driven wheel 9 can be easily engaged, thereby reducing the difficulty of adapting the toothed driving member 4 and the driven wheel 9.

[0079] Additionally, the stop plate 3 and the driven wheel 9 rotate synchronously, which can ensure that the driven wheel 9 drives the stop plate 3 .

[0080] In some embodiments, in combination Figure 3 As shown, the cable includes a first cable 51 and a second cable 52, the first cable 51 is connected to the first cable interface 33; the second cable 52 is connected to the second cable interface 44;

[0081] When the first cable interface 33 is disposed on the toothed driving member 4 , the pulling direction of the first cable 51 is opposite to the pulling direction of the second cable 52 , and both do not coincide with the rotation axis of the toothed driving member 4 .

[0082] 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. Figures 5 to 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.

[0083] Pulling the first cable 51 can directly drive the stop plate 3 to rotate and unlock; pulling the second cable 52 can drive the stop plate 3 to rotate and unlock through the mechanical transmission of the toothed drive member 4.

[0084] 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.

[0085] In some embodiments, in combination Figure 2 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 restoring force for the lock hook 2 to maintain the lock hook 2 in an unlocked state.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] In addition, combined Figure 5 As shown, when the lock hook 2 is in the locked state, under the action of the reset 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 due to the pulling effect of the second cable 52 on the stop plate 3, the stop plate 3 cannot rotate clockwise; or, due to the pulling force of the first cable 51, the toothed driving member 4 cannot rotate counterclockwise, and then through the engagement of the toothed driving member 4 with the driven tooth 91, the stop plate 3 cannot rotate clockwise; and then the lock hook 2 cannot be freely disengaged, thereby ensuring the reliability of the lock hook 2 when it is in the locked state.

[0090] 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.

[0091] In some embodiments, in combination Figure 1 , Figure 2 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 movement of the lock rod 8;

[0092] Along the axial direction of the first pin shaft 22 , the toothed driving member 4 partially penetrates to form a clearance portion 43 , and the clearance portion 43 is suitable for avoiding the movement of the locking rod 8 .

[0093] The toothed driving member 4 is partially penetrated to form a clearance portion 43 , which is suitable for avoiding the movement of the locking rod 8 , so that the locking rod 8 will not interfere with the toothed driving member 4 during the movement.

[0094] 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.

[0095] 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.

[0096] In some embodiments, in combination Figure 3 As shown, the lock hook 2 is provided with a lock slot 23;

[0097] When the lock hook 2 is in the locked state, along the axial direction of the first pin shaft 22 , the lock groove 23 , the lock rod groove 14 and the yielding portion 43 at least partially overlap to form a locking cavity, and the lock rod 8 is located in the locking cavity.

[0098] Combination Figure 2 As shown, along the axial direction of the first pin shaft 22 , the lock groove 23 , the lock rod groove 14 and the evacuation portion 43 at least partially overlap, thereby accommodating the lock rod 8 .

[0099] 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.

[0100] 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.

[0101] In some embodiments, the vehicle comprises a left-hand drive vehicle or a right-hand drive vehicle.

[0102] The vehicle provided by the embodiment of the present invention is provided with a toothed driving member 4, and the active teeth 41 of the toothed driving member 4 are meshed with the driven teeth 91, so that the toothed driving member 4 moves to drive the stop plate 3 to switch between the first state and the second state; and by providing a first cable 51 and a second cable 52, one of the first cable 51 and the second cable 52 is connected to the toothed driving member 4, and the other is connected to the toothed driving member 4 and / or the stop plate 3, so as to realize the two-way unlocking of the hood lock, so as to achieve the cable arrangement of both the left-hand drive vehicle and the right-hand drive vehicle, improve the degree of commonality of parts, and reduce the development cost. And according to the actual installation requirements of the left-hand drive vehicle and the right-hand drive vehicle, 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 the 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 the situation where the damage of parts caused by the inability to open the hood leads to an increase in after-sales maintenance costs.

[0103] 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.
