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. Summary of the invention

[0003] 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.

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

[0005] A lock housing, in which a first pin shaft and a second pin shaft are installed in parallel;

[0006] 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;

[0007] 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;

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

[0009] The cable is located at a first arrangement position and connected to the bidirectional rotating wheel to drive the bidirectional rotating wheel to rotate along a first rotation direction; and / or is located at a second arrangement position and connected to the bidirectional rotating wheel to drive the bidirectional rotating wheel to rotate along a second rotation direction.

[0010] Beneficial effect: The hood lock provided by the embodiment of the present invention is provided with a two-way rotating wheel, and is connected to the two-way rotating wheel by at least one cable. When the cable is located at the first arrangement position, the two-way rotating wheel can be driven to rotate along the first rotation direction by pulling the cable; when the cable is located at the second arrangement position, the two-way rotating wheel can be driven to rotate along the second rotation direction by pulling the cable. It is convenient to pull from two directions to realize 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, reduce development costs, and realize the commonality of left-hand drive vehicles and right-hand drive vehicles. In addition, the hood lock structure design of this embodiment is relatively simple, the number of parts is less, and the manufacturing cost is reduced.

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

[0012] Rotating shaft;

[0013] The wheel body is adapted to rotate around the rotation axis, and the outer peripheral surface of the wheel body surrounding the rotation axis is formed with a first driving profile and a second driving profile;

[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 with the outer peripheral surface of the rotating wheel body surrounding the rotating shaft, and the guide portion is adapted to move relative to the first driving profile surface or the second driving profile surface.

[0018] Beneficial effect: the starting end of the first driving surface and the starting end of the second driving surface are arranged close to each other; when the stop plate is in the first state, the guide part is located between the starting end of the first driving surface and the starting end of the second driving surface, so that when the wheel body rotates around the rotating shaft, whether the guide part moves along the first driving surface or along the second driving surface, the guide part can gradually move away from the axis of the rotating shaft, thereby making the stop plate rotate around the second pin shaft to switch from the first state to the second state.

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

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

[0021] Beneficial effect: By gradually increasing the minimum distance between the first driving profile and the axis of the rotating shaft, the first driving profile can guide the guide part more smoothly and avoid jamming. Similarly, when the guide part moves along the second driving profile, the minimum distance between the second driving profile and the axis of the rotating shaft gradually increases, so that the second driving profile can guide the guide part more smoothly and avoid jamming.

[0022] In an optional embodiment, a positioning portion is further formed on the outer circumferential surface of the wheel body surrounding the rotating shaft, and the positioning portion is located between the starting end of the first driving profile and the starting end of the second driving profile.

[0023] In an optional embodiment, the positioning portion is formed by a local depression of the outer circumference of the rotating wheel body surrounding the rotating shaft.

[0024] Beneficial effect: By forming the positioning portion, the stop plate can be quickly positioned to the positioning portion when it is in the first state, avoiding the guide portion from being still on the first driving surface or the second driving surface after resetting, thereby reducing the unlocking tendency of the stop plate and ensuring that the stop plate can limit the lock hook well.

[0025] In an optional embodiment, the bidirectional rotating wheel further includes: a rotating wheel reset torsion spring, which is suitable for providing a reset force for the rotating wheel body to maintain the rotating wheel body in the first preset position; when the rotating wheel body is in the first preset position, the guide portion is in contact with the positioning portion.

[0026] Beneficial effect: By setting the wheel reset torsion spring, the wheel body can be easily reset to the first preset position after the force of the cable disappears. When the wheel body is in the first preset position, the guide part fits with the positioning part, thereby avoiding the guide part from being still on the first driving surface or the second driving surface after resetting, preventing the stop plate from having an unlocking tendency, and ensuring that the stop plate can limit the lock hook well.

[0027] In an optional embodiment, at least one cable interface portion is provided on the rotating wheel body;

[0028] The cable interface portion is suitable for being connected to the cable, and the pulling direction of the cable does not coincide with the axis of the rotating shaft.

[0029] Beneficial effect: When two cable interfaces are provided on the wheel body, two cables are provided correspondingly, the two cables extend in opposite directions and are respectively connected to a cable interface, so that one of the cables can drive the two-way wheel to rotate in the first rotation direction, and the other cable can drive the two-way wheel to rotate in the second rotation direction. At this time, according to the actual installation requirements of left-hand drive vehicles and right-hand drive vehicles, one of the cables can be used as the main cable and extend into the cab to be connected to the opening handle of the hood cover; the other cable can be used as a spare opening cable, and the opening position of the spare opening cable is arranged in a hidden and easily accessible position, so as to provide a backup opening possibility when the main cable fails, and reduce the occurrence of increased after-sales maintenance costs due to damage to parts caused by the inability to open the hood. By reserving a spare opening mechanism, not only the convenience of maintenance is improved, but also the damage to parts is effectively reduced.

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

[0031] And / or, 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 stop plate in the first state.

[0032] Beneficial effect: Since the first torsion spring is suitable for providing a reset force for the lock hook to maintain the unlocked state, when the lock hook is in the locked state, the first torsion spring is always in a compressed state. When the limiting portion of the stop plate is disengaged from the locking portion of the lock hook, the restriction on the lock hook can be released, and then under the action of the reset force of the first torsion spring, the lock hook is rotated to the unlocked state, thereby facilitating the release of the lock rod. Since the second torsion spring is suitable for providing a reset force for the stop plate to maintain the first state, when the cable is pulled, the elastic force of the second torsion spring needs to be overcome. When the pulling force of the cable disappears, under the action of the reset force of the second torsion spring, the stop plate will return to the position of the first state again.

[0033] 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.

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

[0035] Beneficial effects: The vehicle provided by the embodiment of the present invention is provided with a two-way rotating wheel, and is connected to the two-way rotating wheel by at least one cable. When the cable is located at the first arrangement position, the two-way rotating wheel can be driven to rotate along the first rotation direction by pulling the cable; when the cable is located at the second arrangement position, the two-way rotating wheel can be driven to rotate along the second rotation direction by pulling the cable. It is convenient to pull from two directions to realize 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, reduce development costs, and realize the commonality of left-hand drive vehicles and right-hand drive vehicles. In addition, the hood lock structure design of this embodiment is relatively simple, the number of parts is less, and the production and manufacturing costs are reduced.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[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] The lock housing 1 has a first pin 22 and a second pin 32 installed in parallel therein;

[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 bidirectional rotating wheel 4 is adapted to rotate along a first rotating direction or a second rotating direction around a rotating shaft 42; when the bidirectional rotating wheel 4 rotates along the first rotating direction or the second rotating direction, it is adapted to drive the stop plate 3 to switch between the first state and the second state;

[0062] The cable 5 is located at a first arrangement position and connected to the bidirectional rotating wheel 4 to drive the bidirectional rotating wheel 4 to rotate along a first rotation direction; and / or is located at a second arrangement position and connected to the bidirectional rotating wheel 4 to drive the bidirectional rotating wheel 4 to rotate along a second rotation direction.

[0063] The lock hook 2 of this embodiment is used to limit the lock rod in the locked state, and the lock rod 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 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] 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.

[0067] The rotation of the stop plate 3 around the second pin 32 can be achieved by pulling the cable. 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 sets a two-way rotating wheel 4 and connects the two-way rotating wheel 4 through at least one cable 5. The cable 5 can be arranged in a first arrangement position or a second arrangement position. The arrangement directions of the first arrangement position and the second arrangement position are opposite. When the cable 5 is in the first arrangement position, by pulling the cable 5, the two-way rotating wheel 4 can be driven to rotate in the first rotation direction; when the cable 5 is in the second arrangement position, by pulling the cable 5, the two-way rotating wheel 4 can be driven to rotate in the second rotation direction. This makes it convenient to pull from two directions, which facilitates the commonality of left-hand drive vehicles and right-hand drive vehicles.

[0068] The hood lock provided by the embodiment of the present invention is provided with a two-way rotating wheel 4, and is connected to the two-way rotating wheel 4 by at least one cable 5. When the cable 5 is located at the first arrangement position, the two-way rotating wheel 4 can be driven to rotate along the first rotation direction by pulling the cable 5; when the cable 5 is located at the second arrangement position, the two-way rotating wheel 4 can be driven to rotate along the second rotation direction by pulling the cable 5. It is convenient to pull from two directions to realize 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, reduce development costs, and realize the commonality of left-hand drive vehicles and right-hand drive vehicles. In addition, the hood lock structure design of this embodiment is relatively simple, the number of parts is less, and the production and manufacturing costs are reduced.

[0069] like Figure 1As 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 when the cable 5 is located at the first arrangement position, the cable 5 can be installed at the first lock sleeve connecting position 11; when the cable 5 is located at the second arrangement position, the cable 5 can be installed at the second lock sleeve connecting position 12, thereby realizing the clamping of the cable 5 to prevent it from falling off.

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

[0071] Rotating shaft 42;

[0072] The wheel body 41 is adapted to rotate around the rotating shaft 42. The outer peripheral surface of the wheel body 41 surrounding the rotating shaft 42 is formed with a first driving surface 411 and a second driving surface 412.

[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 suitable for being in contact with the outer circumference of the rotating wheel body 41 around the rotating shaft 42 . The guide portion 33 is suitable for moving relative to the first driving profile 411 or the second driving profile 412 .

[0077] In this 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 outer circumference of the rotating wheel body 41 surrounding the rotating shaft 42 is formed with a first driving surface 411 and a second driving surface 412 ; the first driving surface 411 and the second driving surface 412 are both sections of the outer circumference of the rotating wheel body 41 surrounding the rotating shaft 42 .

[0079] The guide portion 33 is suitable for moving relative to the first driving surface 411 or the second driving surface 412. Specifically, the guide portion 33 can be in sliding contact with the first driving surface 411 or the second driving surface 412. As a deformation, the guide portion 33 can also be a roller or ball structure installed on the stop plate 3, so that the guide portion 33 can be in rolling contact with the first driving surface 411 or the second driving surface 412 to reduce friction and avoid jamming.

[0080] The minimum distance between the starting end of the first driving surface 411 and the axis of the rotating shaft 42 is smaller than the minimum distance between the ending end of the first driving surface 411 and the axis of the rotating shaft 42; thereby, when the guide portion 33 moves from the starting end of the first driving surface 411 to the ending end of the first driving surface 411, the guide portion 33 can gradually move away from the axis of the rotating shaft 42, thereby causing the stop plate 3 to rotate around the second pin shaft 32.

[0081] Similarly, the minimum distance between the starting end of the second driving surface 412 and the axis of the rotating shaft 42 is smaller than the minimum distance between the ending end of the second driving surface 412 and the axis of the rotating shaft 42; thereby, when the guide portion 33 moves from the starting end of the second driving surface 412 to the ending end of the second driving surface 412, the guide portion 33 can gradually move away from the axis of the rotating shaft 42, thereby causing the stop plate 3 to rotate around the second pin shaft 32.

[0082] In this embodiment, the starting end of the first driving surface 411 and the starting end of the second driving surface 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 surface 411 and the starting end of the second driving surface 412, so that when the wheel body 41 rotates around the rotating shaft 42, whether the guide portion 33 moves along the first driving surface 411 or the second driving surface 412, the guide portion 33 can gradually move away from the axis of the rotating shaft 42, thereby causing the stop plate 3 to rotate 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 a guide portion 33 suitable for fitting with the outer circumference of the rotating wheel body 41 around the rotating shaft 42, and the guide portion 33 is suitable for moving relative to the first driving surface 411 or the second driving surface 412; thus, under the pushing action of the rotating wheel body 41, the stop plate 3 can rotate relative to the second pin shaft 32. In this embodiment, combined with Figures 5 to 8 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.

[0084] The outer peripheral surface of the rotating wheel body 41 of this embodiment is designed to be a bidirectionally symmetrical profile, and can equivalently drive the stop plate to unlock regardless of clockwise or counterclockwise rotation.

[0085] In some embodiments, in combination 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 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 of the rotating shaft 42 gradually increases.

[0087] By gradually increasing the minimum distance between the first driving profile 411 and the axis of the rotating shaft 42, the first driving profile 411 can guide the guide portion 33 more smoothly and avoid jamming. Similarly, when the guide portion 33 moves along the second driving profile 412, the minimum distance between the second driving profile 412 and the axis of the rotating shaft 42 can be gradually increased, so that the second driving profile 412 can guide the guide portion 33 more smoothly and avoid jamming.

[0088] In some embodiments, in combination Figure 5 As shown, a positioning portion 413 is further formed on the outer circumferential surface of the rotating wheel body 41 surrounding the rotating shaft 42 , and the positioning portion 413 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 portion 413 is formed by a partial depression of the outer circumference of the rotating wheel body 41 surrounding the rotating shaft 42 .

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

[0091] In some embodiments, in combination Figure 3 As shown, the bidirectional rotating wheel 4 further includes: a rotating wheel reset torsion spring 44, which is suitable for providing a reset force for the rotating wheel body 41 to maintain the rotating wheel body 41 at the first preset position; when the rotating wheel body 41 is at the first preset position, the guide portion 33 fits the positioning portion 413.

[0092] By setting the wheel reset torsion spring 44, the wheel body 41 can be easily reset to the first preset position after the force of the cable 5 disappears. When the wheel body 41 is in the first preset position, the guide portion 33 fits with the positioning portion 413, thereby preventing the guide portion 33 from being still on the first driving surface 411 or the second driving surface 412 after resetting, preventing the stop plate 3 from having an unlocking tendency, and ensuring that the stop plate 3 can limit the lock hook 2 well.

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

[0094] The cable interface portion 43 is suitable for connecting with the cable 5 , and the pulling direction of the cable 5 does not coincide with the axis of the rotating shaft 42 .

[0095] As an optional implementation form, a cable interface portion 43 is provided on the wheel body 41. No matter the cable 5 is located in the first arrangement position or the second arrangement position, it can be connected to the cable interface portion 43, thereby driving the bidirectional wheel 4 to rotate along the first rotation direction or the second rotation direction.

[0096] As another optional implementation form, two cable interface parts 43 are provided on the wheel body 41, and two cables 5 are correspondingly provided. The two cables 5 extend in opposite directions and are respectively connected to a cable interface part 43, so that one of the cables 5 can drive the two-way wheel 4 to rotate in the first rotation direction, and the other cable 5 can drive the two-way wheel 4 to rotate in the second rotation direction. At this time, according to the actual installation requirements of left-hand drive vehicles and right-hand drive vehicles, one of the cables 5 can be used as the main cable and extend into the cab to be connected to the opening handle of the hood cover; the other cable 5 can be used as a spare opening cable, and the opening position of the spare opening cable is arranged in a hidden and easily accessible position, so as to provide a backup opening possibility when the main cable fails, and reduce the occurrence of increased after-sales maintenance costs caused by damage to parts due to the inability to open the hood. By reserving a spare opening mechanism, not only the convenience of maintenance is improved, but also the damage to parts is effectively reduced.

[0097] In some embodiments, in combination Figure 4 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;

[0098] 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.

[0099] 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 removal of the lock rod.

[0100] 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 cable 5 is pulled, the elastic force of the second torsion spring 7 needs to be overcome. When the pulling force of the cable 5 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.

[0101] 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 exert a force on the limiting portion 31 of the stop plate 3, but since the guide portion 33 is pressed against the positioning portion 413, the stop plate 3 cannot rotate clockwise; or, due to the tension of the cable 5, 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.

[0102] 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 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.

[0103] In some embodiments, the lock housing 1 is provided with a lock rod slot 14, and the lock rod slot 14 is suitable for guiding the movement of the lock rod;

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

[0105] 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 is located in the locking cavity.

[0106] The locking principle of the lock rod 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 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 is located in the locking cavity and cannot be removed by itself.

[0107] The unlocking principle of the locking rod 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 can be disengaged along the lock rod groove 14.

[0108] 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.

[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 invention is provided with a two-way rotating wheel 4, and is connected to the two-way rotating wheel 4 by at least one cable 5. When the cable 5 is located at the first arrangement position, the two-way rotating wheel 4 can be driven to rotate along the first rotation direction by pulling the cable 5; when the cable 5 is located at the second arrangement position, the two-way rotating wheel 4 can be driven to rotate along the second rotation direction by pulling the cable 5. It is convenient to pull from two directions to realize 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, reduce development costs, and realize the commonality of left-hand drive vehicles and right-hand drive vehicles. In addition, the hood lock structure design of this embodiment is relatively simple, the number of parts is less, and the production and manufacturing costs are reduced.

[0111] 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.
