TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle lock, in particular to a hood lock and a vehicle. BACKGROUND

[0002] According to the traffic rules of different countries, vehicles are also divided into left-hand drive vehicles and right-hand drive vehicles. When designing the hood lock of the engine, it is necessary to design differently for markets with different driving habits. Left-hand drive vehicles and right-hand drive vehicles cannot use the same hood lock, which undoubtedly increases the difficulty of part generalization. SUMMARY

[0003] Therefore, the present application provides a hood lock and a vehicle to solve the problem that left-hand drive vehicles and right-hand drive vehicles cannot use the same hood lock.

[0004] In a first aspect, the present application provides a hood lock, comprising:

[0005] a lock shell, wherein a first pin shaft and a second pin shaft are installed in parallel inside the lock shell;

[0006] a lock hook adapted to rotate around the first pin shaft to switch between a locked state and an unlocked state, the lock hook having a locking portion;

[0007] a stop plate adapted to rotate around the second pin shaft to switch between a first state and a second state, the stop plate having 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 disengage from the locking portion in the second state to release the restriction on the lock hook;

[0008] a bidirectional rotating wheel adapted to rotate in a first rotating direction or a second rotating direction around a rotating shaft; the bidirectional rotating wheel is adapted to drive the stop plate to switch between the first state and the second state when rotating in the first rotating direction or the second rotating direction;

[0009] a cable located in a first arrangement position and connected to the bidirectional rotating wheel to drive the bidirectional rotating wheel to rotate in the first rotating direction; and / or, a cable located in a second arrangement position and connected to the bidirectional rotating wheel to drive the bidirectional rotating wheel to rotate in the second rotating direction.

[0010] Beneficial effects: The hood lock provided by the embodiment of the present application is provided with a bidirectional rotating wheel, and at least one cable is connected with the bidirectional rotating wheel. When the cable is located at a first arrangement position, the bidirectional rotating wheel can be driven to rotate in a first rotating direction by pulling the cable. When the cable is located at a second arrangement position, the bidirectional rotating wheel can be driven to rotate in a second rotating direction by pulling the cable. Thus, the cable can be pulled from two directions, the hood lock can be unlocked in two directions, the cable arrangement of the left-hand drive vehicle and the right-hand drive vehicle can be simultaneously considered, the degree of generalization of the parts is improved, the development cost is reduced, and the left-hand drive vehicle and the right-hand drive vehicle are generalized. Moreover, the structure of the hood lock of the embodiment is relatively simple, the number of parts is smaller, and the production manufacturing cost is reduced.

[0011] In an alternative embodiment, the bidirectional rotating wheel comprises:

[0012] a rotating shaft;

[0013] a rotating wheel body adapted to rotate around the rotating shaft, the rotating wheel body being formed with a first driving profile and a second driving profile around the outer circumferential surface of the rotating shaft;

[0014] In a plane perpendicular to the axis of the rotating shaft, the minimum distance between the starting end of the first driving profile and the axis of the rotating shaft is smaller than the minimum distance between the ending end of the first driving profile and the axis of the rotating shaft;

[0015] the minimum distance between the starting end of the second driving profile and the axis of the rotating shaft is smaller than the minimum distance between the ending end of the second driving profile and the axis of the rotating shaft;

[0016] the starting end of the first driving profile and the starting end of the second driving profile are arranged close to each other;

[0017] the stop plate is formed with a guide portion adapted to fit the outer circumferential surface of the rotating wheel body around the rotating shaft, and the guide portion is adapted to move relative to the first driving profile or the second driving profile.

[0018] Beneficial effects: The starting end of the first driving profile and the starting end of the second driving profile are arranged close to each other. When the stop plate is in the first state, the guide portion is located between the starting end of the first driving profile and the starting end of the second driving profile. Thus, when the rotating wheel body rotates around the rotating shaft, the guide portion gradually moves away from the axis of the rotating shaft whether it moves along the first driving profile or the second driving profile, so that the stop plate rotates around the second pin shaft to convert from the first state to the second state.

[0019] In an alternative embodiment, the minimum distance between the first driving profile and the axis of the rotating shaft gradually increases from the starting end of the first driving profile to the ending end of the first driving profile;

[0020] And / or, from the start end of the second driving profile to the end end of the second driving profile, the minimum distance between the second driving profile and the axis centerline of the rotating shaft gradually increases.

[0021] Beneficial effect: by gradually increasing the minimum distance between the first driving profile and the axis centerline of the rotating shaft, the first driving profile can be more smoothly guided by the guide part, avoiding jamming. Similarly, the minimum distance between the second driving profile and the axis centerline of the rotating shaft gradually increases, which can make the guide part move along the second driving profile, making the second driving profile more smoothly guided by the guide part, avoiding jamming.

[0022] In an optional embodiment, the rotating body further forms a positioning part around the outer circumferential surface of the rotating shaft, and the positioning part is located between the start end of the first driving profile and the start end of the second driving profile.

[0023] In an optional embodiment, the positioning part is formed by locally recessing the rotating body around the outer circumferential surface of the rotating shaft.

[0024] Beneficial effect: by forming the positioning part, the stop plate can be quickly positioned to the positioning part when it is in the first state, avoiding the guide part being in the first driving profile or the second driving profile after resetting, thereby reducing the unlocking tendency of the stop plate and ensuring that the stop plate can well limit the locking hook.

[0025] In an optional embodiment, the bidirectional rotating wheel further comprises: a rotating body reset torsional spring adapted to provide a reset force for maintaining the rotating body in a first preset position; and when the rotating body is in the first preset position, the guide part is in contact with the positioning part.

[0026] Beneficial effect: by setting the rotating body reset torsional spring, the rotating body can be conveniently reset to the first preset position after the force of the cable disappears, and when the rotating body is in the first preset position, the guide part is in contact with the positioning part, thereby avoiding the guide part being in the first driving profile or the second driving profile after resetting, preventing the stop plate from having an unlocking tendency, and ensuring that the stop plate can well limit the locking hook.

[0027] In an optional embodiment, the at least one cable interface part is arranged on the rotating body.

[0028] The cable interface part is adapted to be connected with the cable, and the pulling direction of the cable is not coincident with the axis centerline of the rotating shaft.

[0029] Beneficial effects: When two cable interface parts are arranged on the rotating body, and two cables are arranged correspondingly, the two cables extend in opposite directions and are connected with one cable interface part respectively, so that one cable can drive the bidirectional rotating wheel to rotate in the first rotating direction, and the other cable can drive the bidirectional rotating wheel to rotate in the second rotating direction. At this time, according to the actual installation requirements of the left-hand drive vehicle and the right-hand drive vehicle, one cable can be used as a main cable and extended into the cab to be connected with the opening handle of the hood cover; the other cable can be used as a backup opening cable, and the opening position of the backup opening cable is arranged at a hidden and easily accessible position, so as to provide a backup opening possibility when the main cable fails, and reduce the situation that the after-sales maintenance cost increases due to the damage of parts caused by the failure to open the hood. By reserving the backup opening mechanism, the maintenance convenience is improved, and the damage to the parts is effectively reduced.

[0030] In an optional embodiment, the hood lock further comprises: a first torsional spring connected with the lock hook and adapted to provide a reset force for the lock hook to maintain the lock hook in the unlocked state.

[0031] And / or, the hood lock further comprises: a second torsional spring connected with the stop plate and adapted to provide a reset force for the stop plate to maintain the stop plate in the first state.

[0032] Beneficial effects: Since the first torsional spring is adapted to provide a reset force for the lock hook to maintain the lock hook in the unlocked state, when the lock hook is in the locked state, the first torsional spring is always in the compressed state, and when the limiting part of the stop plate is disengaged from the locking part of the lock hook, the restriction on the lock hook is released, and then the lock hook is rotated to the unlocked state under the action of the reset force of the first torsional spring, thereby facilitating the disengagement of the lock rod. Since the second torsional spring is adapted to provide a reset force for the stop plate to maintain the stop plate in the first state, when the cable is pulled, the elastic force of the second torsional spring needs to be overcome. When the pulling force of the cable disappears, the stop plate will be reset to the position of the first state under the action of the reset force of the second torsional spring.

[0033] In a second aspect, the present application also provides a vehicle comprising: a vehicle body, and a hood lock arranged on the vehicle body and as described above.

[0034] In an optional embodiment, the vehicle comprises a left-hand drive vehicle or a right-hand drive vehicle.

[0035] Beneficial effects: the vehicle provided by the embodiment of the present application is provided with a bidirectional rotating wheel, and at least one cable is connected with the bidirectional rotating wheel, when the cable is located at a first arrangement position, the bidirectional rotating wheel can be driven to rotate in a first rotating direction by pulling the cable, and when the cable is located at a second arrangement position, the bidirectional rotating wheel can be driven to rotate in a second rotating direction by pulling the cable. Thus, the cable can be pulled from two directions, the hood lock is unlocked in two directions, the cable arrangement of the left-hand drive vehicle and the right-hand drive vehicle is considered at the same time, the degree of generalization of the parts is improved, the development cost is reduced, and the generalization of the left-hand drive vehicle and the right-hand drive vehicle is realized. Moreover, the hood lock structure of the embodiment is relatively simple, the number of parts is less, and the production manufacturing cost is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0051] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0054] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0055] With the globalization of China's automobile industry accelerating, more and more vehicles need to be exported to overseas markets. According to the traffic rules of different countries, vehicles are also divided into left-hand drive vehicles and right-hand drive vehicles. The hood lock of the engine usually needs to be opened by the hood cable, and the opening handle of the hood cable is often arranged on the driver's side, so it needs to be adjusted in different directions for left-hand drive vehicles and right-hand drive vehicles. Therefore, when designing the hood lock of the engine, it is necessary to design differently for markets with different driving habits. Due to the different directions of the pull lines, left-hand drive vehicles and right-hand drive vehicles often cannot use the same hood lock, which undoubtedly increases the difficulty of part generalization and development cost.

[0056] The embodiments of the present application will be described below in combination with Figures 1 to 8

[0057] According to the embodiments of the present application, on the one hand, a hood lock is provided, comprising:

[0058] a lock housing 1, in which a first pin shaft 22 and a second pin shaft 32 are installed in parallel;

[0059] a lock hook 2 adapted to rotate around the first pin shaft 22 to switch between a locked state and an unlocked state, the lock hook 2 having a locking portion 21;

[0060] a stop plate 3 adapted to rotate around the second pin shaft 32 to switch between a first state and a second state, the stop plate 3 having 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] a bidirectional rotating wheel 4 adapted to rotate in a first rotating direction or a second rotating direction around a rotating shaft 42; the bidirectional rotating wheel 4 is adapted to drive the stop plate 3 to switch between the first state and the second state when rotating in the first rotating direction or the second rotating direction;

[0062] a cable 5 located in a first arrangement position and connected to the bidirectional rotating wheel 4 to drive the bidirectional rotating wheel 4 to rotate in the first rotating direction; and / or, located in a second arrangement position and connected to the bidirectional rotating wheel 4 to drive the bidirectional rotating wheel 4 to rotate in the second rotating direction.

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

[0064] The lock housing 1 serves as the shell of the hood lock, and each structural component is adapted to be installed inside the lock housing 1.

[0065] ​By mounting the first pin shaft 22 to the lock shell 1, the rotation of the lock hook 2 around the first pin shaft 22 can be ensured, and the movement of the lock hook 2 relative to the lock shell 1 can be realized. Similarly, by mounting the second pin shaft 32 to the lock shell 1, the rotation of the stop plate 3 around the second pin shaft 32 can be ensured, and the movement of the stop plate 3 relative to the lock shell 1 can be realized.

[0066] The limiting portion 31 of the stop plate 3 and the locking portion 21 of the lock hook 2 are adapted to abut each other, and 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 pulled out of 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 is rotated to switch the stop plate 3 from the first state to the second state, the limiting portion 31 can be separated from the locking portion 21, and the limiting portion 31 can be released from the limitation of the locking portion 21, so as to release the limitation of the lock hook 2, so that the lock hook 2 can be switched from the locked state to the unlocked state.

[0067] The rotation of the stop plate 3 around the second pin shaft 32 can be realized by the traction of the pull cable. Since the directions of the pull cables of the left-hand drive vehicle and the right-hand drive vehicle are different, in order to facilitate the universalization of the left-hand drive vehicle and the right-hand drive vehicle, the embodiment is provided with the bidirectional rotating wheel 4, and at least one pull cable 5 is connected with the bidirectional rotating wheel 4. The pull cable 5 can be arranged in the first arrangement position or the second arrangement position, and the arrangement directions of the first arrangement position and the second arrangement position are opposite. When the pull cable 5 is located in the first arrangement position, the bidirectional rotating wheel 4 can be driven to rotate in the first rotation direction by pulling the pull cable 5; when the pull cable 5 is located in the second arrangement position, the bidirectional rotating wheel 4 can be driven to rotate in the second rotation direction by pulling the pull cable 5. Thus, it is convenient to pull from two directions, and the universalization of the left-hand drive vehicle and the right-hand drive vehicle is facilitated.

[0068] The embodiment of the present application provides the hood lock, the bidirectional rotating wheel 4 is arranged, and at least one pull cable 5 is connected with the bidirectional rotating wheel 4. When the pull cable 5 is located in the first arrangement position, the bidirectional rotating wheel 4 can be driven to rotate in the first rotation direction by pulling the pull cable 5; when the pull cable 5 is located in the second arrangement position, the bidirectional rotating wheel 4 can be driven to rotate in the second rotation direction by pulling the pull cable 5. Thus, it is convenient to pull from two directions, the bidirectional unlocking of the hood lock is realized, the layout of the pull cable of the left-hand drive vehicle and the right-hand drive vehicle is simultaneously considered, the universalization degree of parts is improved, the development cost is reduced, and the universalization of the left-hand drive vehicle and the right-hand drive vehicle is realized. Moreover, the structure design of the hood lock of the embodiment is relatively simple, the number of parts is less, and the production manufacturing cost is reduced.

[0069] As Figure 1As shown, the lock shell 1 is provided with a lock shell fixing hole 13, and the lock shell 1 can be fixed with the vehicle body by inserting a bolt into the lock shell fixing hole 13. The lock shell 1 is provided with a first lock sleeve connecting position 11 and a second lock sleeve connecting position 12. When the pull cable 5 is located at the first arrangement position, the pull cable 5 can be installed at the first lock sleeve connecting position 11; when the pull cable 5 is located at the second arrangement position, the pull cable 5 can be installed at the second lock sleeve connecting position 12, so as to realize clamping of the pull cable 5 and avoid falling off.

[0070] In some embodiments, in combination with Figure 3 As shown, the bidirectional rotating wheel 4 comprises:

[0071] a rotating shaft 42;

[0072] a rotating wheel body 41 adapted to rotate around the rotating shaft 42, and the rotating wheel body 41 is formed with a first driving profile 411 and a second driving profile 412 around the outer circumferential surface of the rotating shaft 42;

[0073] In a plane perpendicular to the axis of the rotating shaft 42, the minimum distance between the starting end of the first driving profile 411 and the axis of the rotating shaft 42 is smaller than the minimum distance between the ending end of the first driving profile 411 and the axis of the rotating shaft 42;

[0074] the minimum distance between the starting end of the second driving profile 412 and the axis of the rotating shaft 42 is smaller than the minimum distance between the ending end of the second driving profile 412 and the axis of the rotating shaft 42;

[0075] the starting end of the first driving profile 411 and the starting end of the second driving profile 412 are arranged close to each other;

[0076] The stop plate 3 is formed with a guide portion 33 adapted to be fitted with the outer circumferential surface of the rotating wheel body 41 around the rotating shaft 42, and the guide portion 33 is adapted to move relative to the first driving profile 411 or the second driving profile 412.

[0077] In the embodiment, the axis of the rotating shaft 42 is parallel to the axis of the first pin shaft 22 and the axis of the second pin shaft 32.

[0078] The rotating wheel body 41 is formed with the first driving profile 411 and the second driving profile 412 around the outer circumferential surface of the rotating shaft 42; the first driving profile 411 and the second driving profile 412 are each a section of the outer circumferential surface of the rotating wheel body 41 around the rotating shaft 42.

[0079] The guide portion 33 is adapted to move relative to the first driving profile 411 or the second driving profile 412, in particular, the guide portion 33 can be in sliding contact with the first driving profile 411 or the second driving profile 412, alternatively, the guide portion 33 can be in rolling contact with the first driving profile 411 or the second driving profile 412, such as a roller or a ball structure, so as to reduce the friction and avoid jamming.

[0080] The minimum distance between the starting end of the first driving profile 411 and the axis of the rotating shaft 42 is smaller than the minimum distance between the ending end of the first driving profile 411 and the axis of the rotating shaft 42, so that when the guide portion 33 moves from the starting end of the first driving profile 411 to the ending end of the first driving profile 411, the guide portion 33 gradually moves away from the axis of the rotating shaft 42, and the stop plate 3 rotates around the second pin shaft 32.

[0081] Similarly, the minimum distance between the starting end of the second driving profile 412 and the axis of the rotating shaft 42 is smaller than the minimum distance between the ending end of the second driving profile 412 and the axis of the rotating shaft 42, so that when the guide portion 33 moves from the starting end of the second driving profile 412 to the ending end of the second driving profile 412, the guide portion 33 gradually moves away from the axis of the rotating shaft 42, and the stop plate 3 rotates around the second pin shaft 32.

[0082] In the embodiment, the starting end of the first driving profile 411 and the starting end of the second driving profile 412 are arranged close to each other, when the stop plate 3 is in the first state, the guide portion 33 is located between the starting end of the first driving profile 411 and the starting end of the second driving profile 412, so that when the rotating body 41 rotates around the rotating shaft 42, the guide portion 33 moves along the first driving profile 411 or the second driving profile 412, and the guide portion 33 gradually moves away from the axis of the rotating shaft 42, and the stop plate 3 rotates around the second pin shaft 32, so as to switch from the first state to the second state.

[0083] Since the stop plate 3 is hinged to the second pin shaft 32, the stop plate 3 is formed with the guide portion 33 adapted to fit the outer circumferential surface of the rotating body 41 around the rotating shaft 42, and the guide portion 33 is adapted to move relative to the first driving profile 411 or the second driving profile 412; so that under the pushing action of the rotating body 41, the stop plate 3 can rotate relative to the second pin shaft 32, in the embodiment, in combination with the change process of the stop plate 3, the stop plate 3 rotates around the second pin shaft 32 in the counterclockwise direction, and with the rotation of the stop plate 3, the limiting portion 31 can be separated from the locking portion 21, so as to release the limitation of the locking hook 2, so as to switch the locking hook 2 from the locked state to the unlocked state. Figures 5 to 8

[0084] ​The outer circumferential surface of the rotating body 41 of the embodiment is designed as a bidirectional symmetrical profile, which can equivalently drive the stop plate to be unlocked whether rotating clockwise or counterclockwise.

[0085] In some embodiments, in combination with Figure 5 As shown, from the starting end of the first driving profile 411 to the ending end of the first driving profile 411, the minimum distance between the first driving profile 411 and the axis center line of the rotating shaft 42 gradually increases.

[0086] And / or, from the starting end of the second driving profile 412 to the ending end of the second driving profile 412, the minimum distance between the second driving profile 412 and the axis center line of the rotating shaft 42 gradually increases.

[0087] By gradually increasing the minimum distance between the first driving profile 411 and the axis center line of the rotating shaft 42, the first driving profile 411 can more smoothly drive the guide part 33, avoiding jamming. Similarly, by gradually increasing the minimum distance between the second driving profile 412 and the axis center line of the rotating shaft 42, the second driving profile 412 can also more smoothly drive the guide part 33 when moving along the second driving profile 412, avoiding jamming.

[0088] In some embodiments, in combination with Figure 5 As shown, the outer circumferential surface of the rotating body 41 around the rotating shaft 42 further forms a positioning part 413, which is located between the starting end of the first driving profile 411 and the starting end of the second driving profile 412.

[0089] In some embodiments, the positioning part 413 is locally recessed from the outer circumferential surface of the rotating body 41 around the rotating shaft 42.

[0090] By forming the positioning part 413, when the stop plate 3 is in the first state, it can be quickly positioned to the positioning part 413, avoiding the guide part 33 being still in the first driving profile 411 or the second driving profile 412 after resetting, thereby reducing the unlocking tendency of the stop plate 3 and ensuring that the stop plate 3 can well limit the locking hook 2.

[0091] In some embodiments, in combination with Figure 3 As shown, the bidirectional rotating wheel 4 further comprises a rotating wheel reset torsional spring 44 adapted to provide a reset force for maintaining the rotating body 41 in a first preset position; when the rotating body 41 is in the first preset position, the guide part 33 is in close contact with the positioning part 413.

[0092] By setting the rotating wheel reset torsion spring 44, the rotating wheel body 41 can be conveniently reset to the first preset position after the force of the cable 5 disappears. When the rotating wheel body 41 is in the first preset position, the guide part 33 is in contact with the positioning part 413, thereby avoiding the guide part 33 being still in the first driving profile 411 or the second driving profile 412 after resetting, preventing the stop plate 3 from having an unlocking trend, and ensuring that the stop plate 3 can well limit the locking hook 2.

[0093] In some embodiments, in combination Figure 3 As shown, the at least one cable interface part 43 is arranged on the rotating wheel body 41.

[0094] The cable interface part 43 is adapted to be connected with the cable 5, and the tension direction of the cable 5 is not coincident with the axis of the rotating shaft 42.

[0095] As an optional implementation form, the rotating wheel body 41 is provided with one cable interface part 43, which can be connected with the cable 5 regardless of whether the cable 5 is located in the first arrangement position or the second arrangement position, thereby driving the bidirectional rotating wheel 4 to rotate in the first rotating direction or the second rotating direction.

[0096] As another optional implementation form, the rotating wheel body 41 is provided with two cable interface parts 43, and two cables 5 are correspondingly arranged, the two cables 5 extend in opposite directions and are respectively connected with one cable interface part 43, so that one of the cables 5 can drive the bidirectional rotating wheel 4 to rotate in the first rotating direction, and the other cable 5 can drive the bidirectional rotating wheel 4 to rotate in the second rotating direction. At this time, according to the actual installation requirement of the left-hand drive vehicle and the right-hand drive vehicle, one of the cables 5 can be used as a main cable and extend into the cab to be connected with the opening handle of the hood cover; the other cable 5 can be used as a backup opening cable, and the opening position of the backup opening cable is arranged at a hidden and easily accessible position, so as to provide a backup opening possibility when the main cable fails, and reduce the situation that the after-sales maintenance cost increases due to the damage of parts caused by the failure to open the hood. By reserving the backup opening mechanism, the maintenance convenience is improved, and the damage to the parts is effectively reduced.

[0097] In some embodiments, in combination Figure 4 As shown, the hood lock further includes a first torsion spring 6 connected with the locking hook 2 and adapted to provide a reset force for maintaining the locking hook 2 in the unlocked state.

[0098] And / or, the hood lock further includes a second torsion spring 7 connected with the stop plate 3 and adapted to provide a reset force for maintaining the stop plate 3 in the first state.

[0099] Since the first torsion spring 6 is adapted to provide a reset force for maintaining the locking hook 2 in the unlocked state, when the locking 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 locking hook 2, the limitation of the locking hook 2 is released, and then under the action of the reset force of the first torsion spring 6, the locking hook 2 is rotated to the unlocked state, and then the lock rod is conveniently pulled out.

[0100] Since the second torsion spring 7 is adapted to provide a reset force for maintaining the stop plate 3 in the first state, when the pull cable 5 is pulled, the elastic force of the second torsion spring 7 needs to be overcome. When the pulling force of the pull cable 5 disappears, under the action of the reset force of the second torsion spring 7, the stop plate 3 will be reset to the position of the first state again.

[0101] In addition, in combination with Figure 5 As shown in the figure, when the locking 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 locking hook 2 will act on the limiting portion 31 of the stop plate 3, but because the guide portion 33 abuts against the positioning portion 413, the stop plate 3 cannot rotate clockwise; or because of the pulling force of the pull cable 5, the stop plate 3 cannot rotate clockwise; and then the locking hook 2 cannot be freely pulled out, thereby ensuring the reliability of the locking hook 2 in the locked state.

[0102] In the embodiment, the lock shell 1 is fixedly installed on the vehicle body, the locking hook 2 is fixedly connected with the shell through the first pin shaft 22, and the first torsion spring 6 is sleeved on the first pin shaft 22 and connected with the locking hook 2. Under the action of external force, usually when the engine hood is closed downward, the downward pressure of the lock rod on the locking hook 2 can make the locking 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 above the limiting portion 31 to below the limiting portion 31, thereby realizing locking.

[0103] In some embodiments, the lock shell 1 is provided with a lock rod slot 14, and the lock rod slot 14 is adapted to guide the movement of the lock rod;

[0104] The locking hook 2 is provided with a lock slot 23.

[0105] When the locking hook 2 is in the locked state, the lock slot 23 and the lock rod slot 14 at least partially overlap in the axial direction of the first pin shaft 22 to form a locking cavity, and the lock rod is located in the locking cavity.

[0106] The locking principle of the locking rod in the embodiment is as follows: the locking hook 2 is provided with a locking portion 21 extending into the locking rod slot 14, so that when the locking rod moves along the moving path, the locking portion 21 can be hit to drive the locking hook 2 to rotate, when the locking hook 2 rotates towards the locking direction, the limiting portion 31 is pressed to drive the stop plate 3 to rotate, when the locking hook 2 is in the locking position, the locking portion 21 is clamped by the limiting portion 31 of the stop plate 3 to keep in the locking position. At this time, the opening direction of the locking slot 23 is opposite to the opening direction of the locking rod slot 14, and the locking rod is located in the locking cavity and cannot be pulled out by itself.

[0107] The unlocking principle of the locking rod in the embodiment is as follows: the cable 5 drives the stop plate 3 to rotate, so that the limiting portion 31 is separated from the locking portion 21 to release the restriction on the locking hook 2, so that the locking hook 2 is switched from the locking state to the unlocking state; at this time, the opening directions of the locking slot 23 and the locking rod slot 14 are both upwards, and the locking rod can be pulled out along the locking rod slot 14.

[0108] According to the embodiment of the present application, on the other hand, a vehicle is also provided, comprising: a vehicle body, and a hood lock as described above arranged on the vehicle body.

[0109] In some embodiments, the vehicle comprises a left-hand drive vehicle or a right-hand drive vehicle.

[0110] The vehicle provided by the embodiment of the present application is provided with a bidirectional rotating wheel 4, and the bidirectional rotating wheel 4 is connected with at least one cable 5, when the cable 5 is in the first arrangement position, the bidirectional rotating wheel 4 can be driven to rotate in the first rotating direction by pulling the cable 5, and when the cable 5 is in the second arrangement position, the bidirectional rotating wheel 4 can be driven to rotate in the second rotating direction by pulling the cable 5. Thus, it is convenient to pull from two directions, the bidirectional unlocking of the hood lock is realized, the layout of the pull cable for the left-hand drive vehicle and the right-hand drive vehicle is simultaneously considered, the degree of generalization of the parts is improved, the development cost is reduced, and the generalization of the left-hand drive vehicle and the right-hand drive vehicle is realized. Moreover, the structure of the hood lock in the embodiment is relatively simple, and the number of parts is less, so that the production manufacturing cost is reduced.

[0111] Obviously, the above embodiments are only examples for clearly illustrating, and are not limitation on the embodiments. Although the embodiments of the present application are described in combination with the drawings, various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope defined by the present application.
