A front cover lock, vehicle, and control method

Abstract

The application relates to a front cover lock, a vehicle and a control method, and relates to the field of automobile bodies. The front cover lock comprises a base, a lock pin, a locking mechanism and a driving piece. During the switching of the locking mechanism from the locked state to the unlocked state, the driving piece applies opposite forces to the stop portions of the two locking pieces, so that the stop portions of the two locking pieces are away from the locking portions, and the locking mechanism is switched from the locked state to the unlocked state. When the vehicle is subjected to a biasing collision, the two locking pieces are subjected to lateral impact forces in the same direction, so that the stop portion of one of the locking pieces is away from the locking portion, and the stop portion of the other locking piece is still located on the side of the locking portion close to the front cover of the vehicle, so that the locking mechanism is still in the locked state. That is, when the vehicle is subjected to a biasing collision, the front cover of the vehicle can be kept in the closed state, so that the safety of the front cover lock of the vehicle is improved. Therefore, the application solves the technical problem of low safety of the front cover lock of the vehicle in the related art.

Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to the field of automotive body technology, specifically to a front hood lock, a vehicle, and a control method. Background Technology

[0002] The front hood lock is located at the front of the vehicle. By locking and unlocking the front hood lock, the vehicle's front hood can be locked and opened.

[0003] In related technologies, the front hood lock includes a locking pin, a ratchet, and a pawl. The locking pin is connected to the front hood of the vehicle, and the ratchet and pawl are rotatably connected to the vehicle body. When the front hood lock locks the front hood of the vehicle, the ratchet is rotated so that part of the ratchet is above the locking pin, thereby restricting the upward movement of the locking pin to prevent the front hood from opening. At this time, the pawl abuts against the ratchet, limiting the ratchet. When the front hood lock opens the front hood of the vehicle, the pawl releases its limitation on the ratchet. By rotating the ratchet, the ratchet is rotated to one side of the locking pin in the width direction of the vehicle, thereby releasing the restriction on the locking pin and facilitating the opening of the front hood of the vehicle.

[0004] When the front hood is locked using the aforementioned front hood lock, if an offset collision occurs (i.e., the front left or right side of the vehicle collides), the front hood lock will be subjected to a significant impact force. If this impact force is in the same direction as the force that the pawl should experience when releasing the ratchet, the pawl will rotate due to inertia, thus releasing the ratchet from its restraint. This will cause the ratchet to rotate to one side of the locking pin, releasing its restraint. This will cause the front hood lock to switch from the locked state to the unlocked state, allowing the front hood to open, potentially damaging the vehicle and increasing the risk of a traffic accident. Summary of the Invention

[0005] This application provides a front grille lock, a vehicle, and a control method to at least solve the technical problem of low security in vehicle front grille locks in related technologies. The technical solution of this application is as follows:

[0006] According to a first aspect of this application, a front hood lock is provided, including a base, a locking pin, a locking mechanism, and a driving member. The locking pin includes a connecting portion and a locking portion. The connecting portion is used to connect to the front hood of a vehicle, and the locking portion is located on the side of the connecting portion away from the front hood and is connected to the connecting portion. The locking mechanism has a locked state and an unlocked state, and the driving member is used to drive the locking mechanism to switch between the locked state and the unlocked state.

[0007] The locking mechanism includes two locking members connected to a base and movable relative to the base. The two locking members are spaced apart along a first direction, with a locking portion located between the two locking members. The first direction is perpendicular to the arrangement direction of the connecting portion and the locking portion. Each locking member includes a stop portion. When the locking mechanism is in the locked state, the stop portions of the two locking members are located on the side of the locking portion closer to the front hood. During the process of switching the locking mechanism from the locked state to the unlocked state, the driving member applies opposite forces to the stop portions of the two locking members to move the stop portions of the two locking members away from the locking portion.

[0008] According to the above technical means, since the connecting part of the locking pin is connected to the front cover, when the stop parts of both locking members move to the side of the locking part of the locking pin near the front cover, the stop parts of both locking members can restrict the movement of the locking part towards the front cover, thereby restricting the movement of the front cover away from the locking pin, thus locking the front cover. During the process of switching the locking mechanism from the locked state to the unlocked state, the driving member needs to apply opposite forces to the stop parts of the two locking members to make the stop parts of both locking members move away from the locking part, thereby releasing the restriction of the locking part by the stop parts of both locking members, thus switching the locking mechanism from the locked state to the unlocked state, so as to open the front cover.

[0009] In this way, when an offset collision occurs, the impact force acting on the vehicle is transmitted to the locking mechanism. The two locking members experience the same direction of impact force, ensuring that only one locking member receives the force in the same direction as the force it should experience during the transition from locked to unlocked state. Consequently, the stop portion of one locking member is moved away from the locking section, while the stop portion of the other locking member remains on the side of the locking section closest to the hood. This ensures that the stop portion of the other locking member continues to restrict the side of the locking section closest to the hood, keeping the locking mechanism locked. This design allows the hood to remain closed during an offset collision, thus improving the security of the hood lock.

[0010] In one possible implementation, the locking member further includes a rotating part, which is rotatably connected to the base. The rotation axis of the rotating part is perpendicular to the first direction and perpendicular to the arrangement direction of the connecting part and the locking part. The stop part is connected to the rotating part.

[0011] According to the above-mentioned technical means, this application provides a rotating part connected to the stop part, so that when the rotating part rotates along its rotation axis, it can drive the stop part to rotate along the rotation axis of the rotating part, thereby enabling the stop part to move from the side of the locking part near the front cover to the side away from the locking part, thereby realizing the switching of the locking mechanism between the locked state and the unlocked state.

[0012] In one possible implementation, the rotating parts of the two locking members rotate in opposite directions.

[0013] According to the above-mentioned technical means, the rotating parts of the two locking members in this application rotate in opposite directions, which can reduce the possibility of the locking members being accidentally unlocked due to other external forces. For example, when the front of the vehicle is subjected to an offset collision, both locking members will be subjected to a large lateral impact force in the same direction. If the rotating parts of the two locking members rotate in opposite directions, one of the two rotating parts will drive the corresponding stop part away from the locking part, while the other of the two rotating parts will not rotate, or will drive the corresponding stop part to rotate, but will not move away from the locking part, so that the locking mechanism remains in the locked state.

[0014] In this way, the rotating parts of the two locking components in this application rotate in opposite directions, which can prevent accidental unlocking, improve the stability of the front cover lock, and thus enhance vehicle safety.

[0015] In one possible implementation, the locking member further includes a first limiting part, and the locking mechanism further includes two limiting members connected to the base and capable of moving relative to the base. The two limiting members correspond one-to-one with the two locking members.

[0016] The limiting member includes a second limiting portion. When the locking mechanism is in the locked state, the second limiting portion of the limiting member abuts against the first limiting portion of the locking member to restrict the movement of the locking member. When the locking mechanism is in the unlocked state, the second limiting portion of the limiting member separates from the first limiting portion of the locking member.

[0017] According to the above-mentioned technical means, by setting a first limiting part and a second limiting part, when the first limiting part and the second limiting part are in a contact state, the movement of the locking member can be restricted, thereby making the locking mechanism in a locked state. When the first limiting part and the second limiting part are in a separated state, the stop part of the locking member can move away from the locking part, thereby making the locking mechanism in an unlocked state.

[0018] In one possible implementation, the driving component includes a first cable, a second cable, and a third cable. One end of the first cable is connected to a limiting member for moving the limiting member; one end of the second cable is connected to another limiting member for moving the other limiting member; and the third cable is connected to the other ends of both the first and second cables for moving both the first and second cables.

[0019] Based on the aforementioned technical means, this application, by setting a first cable, a second cable, and a third cable, ensures that pulling the third cable causes the first and second cables to move simultaneously, thus guaranteeing the synchronicity of unlocking. Furthermore, the structure is simple and the cost is low.

[0020] In one possible implementation, the drive unit further includes a junction box and a slider. The junction box has a receiving cavity, the slider is disposed within the receiving cavity and is capable of sliding within the cavity. Along the sliding direction of the slider, one end of the slider is connected to the other end of the first cable and the other end of the second cable, and the other end of the slider is connected to a third cable.

[0021] Based on the above technical means, this application sets up a junction box and a slider, so that while the third cable pulls the slider, it can simultaneously pull the first cable and the second cable. In addition, the receiving cavity has a guiding function, which can ensure that the slider slides along a determined path, thereby improving the reliability of the drive component.

[0022] In one possible implementation, the limiting member further includes a rotating part, which is rotatably connected to the base. The rotation axis of the rotating part is perpendicular to the first direction and perpendicular to the arrangement direction of the connecting part and the locking part. The second limiting part is connected to the rotating part.

[0023] According to the above-mentioned technical means, this application provides a rotating part, which, when the rotating part rotates along its rotation axis, can drive the second limiting part to rotate along the rotation axis of the rotating part. This allows the second limiting part to drive the first limiting part to rotate along the rotation axis of the rotating part, thereby switching the second limiting part and the first limiting part from a contact state to a separation state, and thus realizing the switching of the locking mechanism between the locked state and the unlocked state.

[0024] In one possible implementation, the locking mechanism further includes a reset member connected to the base plate. The reset member is connected to at least one of the two limiting members, and after the second limiting portion separates from the first limiting portion, the reset member is used to reset the limiting member. And / or, the reset member is connected to at least one of the two locking members, and during the switching of the locking mechanism from a locked state to an unlocked state, the reset member is used to move the stop away from the locking portion.

[0025] According to the above technical means, this application sets a reset member connected to a limiting member, so that the limiting member can return to its original position after the second limiting part is separated from the first limiting part, ensuring that when the locking mechanism is in the locking state again, the second limiting part can abut against the first limiting part to restrict the movement of the locking member.

[0026] This application connects a reset member to a locking member, so that the stop portion of the locking member can move away from the locking member during the process of the second limiting member and the first limiting member switching from an abutting state to a separating state, thereby switching the locking mechanism from a locked state to an unlocked state.

[0027] In this way, when the front cover needs to be opened, the reset component helps to quickly release the lock, making operation more convenient. When the front cover is closed, the reset component can automatically reset the limit component, ensuring that the front cover is locked again. By setting a reset component, this application can improve the security, convenience, and reliability of the front cover lock, helping to ensure the normal operation of the front cover lock and the safety of the user.

[0028] In one possible implementation, the reset member includes two elastic members connected to the substrate. One elastic member is connected to a limiting member and a locking member, and the other elastic member is connected to another limiting member and another locking member.

[0029] According to the above technical means, by connecting an elastic element to a limiting element and a locking element respectively, the limiting element and the corresponding locking element can move relative to each other within a certain range, thereby adjusting the relative position between the limiting element and the corresponding locking element to a certain extent, so that the second limiting part abuts or separates from the first limiting part, thereby realizing the switching of the locking mechanism between the locking state and the unlocking state.

[0030] In addition, using only one elastic element can simplify the structure, save space, and reduce assembly complexity.

[0031] In one possible implementation, the stop portion includes a first sub-stop portion and a second sub-stop portion. When the locking mechanism is in the unlocked state, for any one of the locking members, the first sub-stop portion is located on the side of the second sub-stop portion closer to the locking portion. When the locking mechanism is in the locked state, the locking portion abuts against the second sub-stop portions of both locking members. The locking mechanism also has a semi-locked state, in which the locking portion abuts against the first sub-stop portions of both locking members.

[0032] Based on the aforementioned technical means, this application, by setting a first sub-stop and a second sub-stop, enables the locking mechanism to have a locked state and a semi-locked state, which can prevent the front cover from being unlocked prematurely due to misoperation, thereby improving the reliability and security of the front cover lock.

[0033] In one possible implementation, the locking member further includes a third limiting portion, wherein when the locking mechanism is in a semi-locked state, the second limiting portion of one limiting member abuts against the third limiting portion of the locking member to restrict the movement of the locking member.

[0034] According to the above-mentioned technical means, this application provides a third limiting part, which restricts the movement of the locking member when the third limiting part abuts against the second limiting part, so that the locking mechanism is in a semi-locked state.

[0035] In one possible implementation, the base includes a substrate, with one locking member located on one side of the substrate and another locking member located on the other side of the substrate along the thickness direction of the substrate. The thickness direction of the substrate is perpendicular to the first direction and perpendicular to the arrangement direction of the connecting portion and the locking portion.

[0036] According to the above technical means, by setting two locking members at intervals in the thickness direction of the substrate, the swaying and shaking of the substrate in its thickness direction can be effectively prevented, thereby improving the structural stability and reliability of the front cover lock.

[0037] In one possible implementation, the substrate has a receiving groove on the surface near the front cover, the locking part is received in the receiving groove, and can move along the depth direction of the receiving groove.

[0038] Based on the above technical means, this application provides a receiving groove on the substrate, which can effectively position and guide the movement direction of the locking pin, thereby ensuring that the locking pin always moves along the depth direction of the receiving groove during the movement process, without deviating from the predetermined trajectory, thus improving the stability and reliability of the locking pin, and thus ensuring the reliability of the front cover lock.

[0039] According to a second aspect provided in this application, a vehicle is provided that includes the aforementioned front hood lock.

[0040] Based on the aforementioned technical means, this application uses the aforementioned front hood lock in the vehicle, so that when the vehicle is subjected to an offset collision, the locking mechanism remains locked, thereby keeping the front hood closed and improving the safety of the vehicle and the user.

[0041] According to a third aspect provided in this application, a control method for a front cover lock is provided, applied to the aforementioned front cover lock, the control method comprising:

[0042] When a command to unlock the front cover is received, the control drive applies opposite forces to the stops of the two locking parts, so that the stops of the two locking parts move away from the locking parts, thereby switching the locking mechanism from the locked state to the unlocked state.

[0043] The control pin moves away from the locking mechanism along the front cover to separate the lock pin from the locking mechanism.

[0044] And / or, upon receiving a command to close the front hood lock, the control lock pin moves along the front hood toward the locking mechanism, so that the locking part moves between the two locking elements.

[0045] Move the stop portions of the two locking parts to the side of the locking part closer to the front cover, so that the locking mechanism switches from the unlocked state to the locked state.

[0046] Based on the above technical means, this application can accurately control the opening and closing of the vehicle's front hood lock through the above control method. The vehicle's front hood lock will not be accidentally opened due to a lateral collision, thereby enhancing the safety of the vehicle during driving and avoiding safety accidents.

[0047] Meanwhile, the locking mechanism of this application has a simple structure and is stable. Although the driver and passengers can control the front hood lock with simple operation, the front hood lock needs to be opened by applying force in two directions during the control process, which has extremely high stability.

[0048] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0049] (1) When the vehicle is involved in an offset collision, both locking parts in the front cover lock of this application will be subjected to lateral impact force in the same direction, causing the stop part of one locking part to move away from the locking part, while the stop part of the other locking part remains on the side of the locking part close to the front cover, so that the locking mechanism remains locked and the front cover remains closed, thereby improving the safety of the vehicle front cover lock.

[0050] (2) This application sets up a first cable, a second cable, and a third cable, so that when the third cable is pulled, the first and second cables can move simultaneously, ensuring the synchronicity of unlocking. In addition, the structure is simple and the cost is low.

[0051] (3) The rotating parts of the two locking parts in this application rotate in opposite directions, which can prevent accidental unlocking, improve the stability of the front cover lock, and thus enhance the safety of the vehicle.

[0052] It should be noted that the technical effects of any of the implementation methods in the second and third aspects can be found in the technical effects of the corresponding implementation methods in the first aspect, and will not be repeated here.

Detailed Implementation

[0086] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0087] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0088] For ease of understanding, the front cover lock and the vehicle provided in this application will be described in detail below with reference to the accompanying drawings.

[0089] Vehicle collision safety requirements are becoming increasingly stringent, especially offset collisions, which place higher demands on the reliability of the front hood lock. For example... Figure 1 As shown, there is an obstacle A in front of the right side of the vehicle. Due to other reasons, the front right side of the vehicle collides with obstacle A. This is called an offset collision.

[0090] In related technologies, the front hood lock includes a locking pin, a ratchet, and a pawl. The locking pin is connected to the vehicle's front hood, while the ratchet and pawl are rotatably connected to the vehicle body. By rotating the ratchet, a portion of the ratchet is positioned above the locking pin, restricting the pin's upward movement and thus locking the vehicle's front hood. At this time, the pawl abuts against the ratchet, limiting its movement. By rotating the ratchet, it rotates to one side of the locking pin, releasing the restriction on the locking pin and unlocking the vehicle's front hood.

[0091] When a vehicle is involved in an offset collision, the hood lock will be subjected to significant impact forces and moments in both the vertical and lateral directions. This may cause the ratchet and pawl to rotate due to inertia, thereby unlocking the hood lock and opening the hood. If the hood is open while the car is in motion, it will obstruct the driver's view, preventing the driver from clearly seeing the road ahead and other vehicles, increasing the risk of a traffic accident.

[0092] refer to Figure 2 This application provides a front cover lock for use in a vehicle. The front cover lock includes a locking pin 20 and a locking mechanism 30, which is used to lock and unlock the locking pin 20.

[0093] Among them, reference Figure 3 The locking pin 20 includes a connecting portion 21 and a locking portion 22. The connecting portion 21 is used to connect to the front cover (not shown in the figure), and the locking portion 22 is located on the side of the connecting portion 21 away from the front cover and is connected to the connecting portion 21. The locking pin 20 extends along... Figure 2 As shown, the connecting part 21 and the locking part 22 of the locking pin 20 are arranged along the movement direction of the locking pin 20, which moves in the up and down direction.

[0094] For example, the connecting part 21 and the locking part 22 can be an integral structure, which can improve the structural stability of the locking pin 20. Of course, the connecting part 21 and the locking part 22 can also be separate structures, and the connecting part 21 can be fixedly connected to the locking part 22 by means of threaded connection, welding or other methods.

[0095] The front cover lock also includes a drive unit (not shown in the figure). The locking mechanism 30 has a locked state and an unlocked state, and the drive unit is used to provide driving force to the locking mechanism 30, thereby driving the locking mechanism 30 to switch between the locked state and the unlocked state.

[0096] For example, the driving component can be a pull rope, a rotating wheel, a driving rod, etc. During the collision between the vehicle and the obstacle A, the impact force generated by the obstacle A on the vehicle can also serve as the driving force for switching the locking mechanism 30 between the locked state and the unlocked state.

[0097] refer to Figure 4 and combined Figure 3 The locking mechanism 30 includes two locking members 31, which are spaced apart along a first direction. The locking part 22 is located between the two locking members 31. The first direction is perpendicular to the arrangement direction of the connecting part 21 and the locking part 22.

[0098] For example, the first direction can be Figure 4 The left and right directions shown are shown, but of course, the first direction can also be perpendicular to... Figure 4 The direction shown is left-right and perpendicular to the arrangement direction of the connecting part 21 and the locking part 22.

[0099] refer to Figures 5 to 7 and combined Figure 3 The locking member 31 includes a stop portion 311. When the locking mechanism 30 is in the locked state, the stop portions 311 of the two locking members 31 are located on the side of the locking portion 22 near the front cover.

[0100] refer to Figure 8 and combined Figures 5 to 7 During the process of switching the locking mechanism 30 from the locked state to the unlocked state, the driving member applies opposite forces to the stop portions 311 of the two locking members 31, so that the stop portions 311 of the two locking members 31 move away from the locking portion 22 (see...). Figure 3 This causes the locking mechanism 30 to be in the unlocked state.

[0101] When the locking mechanism 30 is in the unlocked state, the stop portions 311 of the two locking members 31 are located on the side of the locking portion 22 in the first direction. That is, the stop portions 311 of the two locking members 31 can be located on opposite sides of the locking portion 22 in the first direction, or they can be located on the same side of the locking portion 22 in the first direction. At this time, neither of the stop portions 311 of the two locking members 31 limits the locking portion 22 on the side near the front cover, thereby allowing the locking pin 20 to move toward the front cover to open the front cover.

[0102] Based on this, when an offset collision occurs, the impact force acting on the vehicle is transmitted to the locking mechanism 30. The lateral impact forces on the two locking members 31 are in the same direction. That is, the direction of the impact force on one locking member 31 is the same as the direction of the force it should receive during the transition from the locked to the unlocked state. This causes the stop portion 311 of one locking member 31 to move away from the locking part 22. The direction of the impact force on the other locking member 31 is opposite to the direction of the force it should receive during the transition from the locked to the unlocked state. At this time, the stop portion 311 of the other locking member 31 does not move away from the locking part 22; that is, the stop portion 311 of the other locking member 31 remains located on the side of the locking part 22 closest to the front hood, thus keeping the locking mechanism 30 in the locked state. With this configuration, the front hood can remain closed during an offset collision, thereby improving the safety of the vehicle's front hood lock.

[0103] Continue to refer to Figure 6 and Figure 7 For example, the stop 311 can be a hook-shaped structure. When the locking mechanism 30 is in the locked state, the inner side of the hook-shaped structure is located above the locking part 22 and abuts against the locking part 22, thereby restricting the movement of the locking part 22. After the driving member applies a force to the stop 311, the inner side of the hook-shaped structure separates from the locking part 22, so that the locking part 22 can move up and down, thereby unlocking the front cover lock.

[0104] Continue to refer to Figure 4 The front cover lock also includes a base 10, with two locking members 31 connected to the base 10 and movable relative to the base 10.

[0105] In some embodiments, both locking members 31 may be slidably connected to the base 10; of course, both locking members 31 may also be rotatably connected to the base 10.

[0106] In other possible embodiments, one of the two locking members 31 is slidably connected to the base 10, and the other of the two locking members 31 is rotatably connected to the base 10, as long as it is ensured that when the driving member applies opposite forces to the stop portions 311 of the two locking members 31, the stop portions 311 can move away from the locking portion 22, thereby enabling the locking mechanism 30 to switch from the locked state to the unlocked state.

[0107] refer to Figure 9 and combined Figure 4 The base 10 includes a substrate 11.

[0108] When the first direction is Figure 4 In the left-right direction shown, along the thickness direction of the substrate 11, the two locking members 31 can both be located on the same side of the substrate 11.

[0109] Of course, for reference Figure 10 The two locking members 31 can also be located on opposite sides of the substrate 11. In this case, the thickness direction of the substrate 11 is perpendicular to the first direction and perpendicular to the arrangement direction of the connecting part 21 and the locking part 22.

[0110] When the first direction is Figure 4 In the front-back direction shown, along the thickness direction of the substrate 11, the two locking members 31 are located on opposite sides of the substrate 11.

[0111] Based on this, by providing two locking members 31 at intervals in the thickness direction of the substrate 11, the swaying and shaking of the substrate 11 in its thickness direction can be effectively prevented, thereby improving the structural stability and reliability of the front cover lock.

[0112] Continue to refer to Figure 6 and Figure 7 In some embodiments, the two locking elements 31 can be identical, thus simplifying the assembly of the two locking elements 31 and making them easier to control.

[0113] Of course, the two locking members 31 can also be different, as long as it is ensured that when the driving member applies opposite forces to the stop portions 311 of the two locking members 31, the stop portions 311 can move away from the locking portion 22, thereby allowing the locking mechanism 30 to switch from the locked state to the unlocked state.

[0114] Continue to refer to Figure 3 and Figure 9 In some embodiments, the substrate 11 has a receiving groove 111 on the surface near the front cover, the locking part 22 is received in the receiving groove 111 and can move along the depth direction of the receiving groove 111.

[0115] Based on this, this application provides a receiving groove 111 on the substrate 11, which enables the receiving groove 111 to effectively position and guide the moving direction of the locking pin 20, thereby ensuring that the locking pin 20 always moves along the depth direction of the receiving groove 111 during the movement process, without deviating from the predetermined trajectory. While making full use of the structure of the substrate 11, it improves the stability and reliability of the locking pin 20, thereby ensuring the reliability of the front cover lock.

[0116] Continue to refer to Figure 5 and Figure 6 In some embodiments, the locking member 31 further includes a rotating part 312, which is rotatably connected to the base 10. The rotation axis of the rotating part 312 is perpendicular to the first direction and perpendicular to the connecting part 21 (see...). Figure 3 ) and locking part 22 (see Figure 3 The arrangement direction of the rotating part 312, that is, the rotation axis of the rotating part 312 and the substrate 11 (see Figure 8The thickness direction of the parts is parallel, and the stop part 311 is connected to the rotating part 312.

[0117] Based on this, when the rotating part 312 rotates along its rotation axis, it can drive the stop part 311 to rotate along the rotation axis of the rotating part 312, so that the stop part 311 can move closer to or away from the locking part 22 in the first direction from the side of the locking part 22 near the front cover, thereby realizing the switching of the locking mechanism 30 between the locked state and the unlocked state.

[0118] In some embodiments, the rotating portions 312 of the two locking members 31 rotate in opposite directions.

[0119] Based on this, the rotating parts 312 of the two locking members 31 in this application rotate in opposite directions, which can reduce the possibility of the locking members 31 being accidentally unlocked due to other external forces.

[0120] For example, continue to refer to Figures 5 to 8 When the driving member applies a force to the left to one of the two locking members 31, the rotating part 312 of the locking member 31 can rotate clockwise, causing the stop part 311 of the locking member 31 to move away from the locking part 22, and finally rotate to one side of the locking part 22 in the first direction; when the driving member applies a force to the right to the other of the two locking members 31, the rotating part 312 of the locking member 31 can rotate counterclockwise, and finally rotate to the other side of the locking part 22 in the first direction, causing the stop part 311 of the locking member 31 to move away from the locking part 22.

[0121] When the front of the vehicle is subjected to an offset collision, both locking parts 31 will be subjected to a large lateral impact force in the same direction, such as to the left. If the rotation directions of the rotating parts 312 of the two locking parts 31 are opposite, one of the two rotating parts 312 will drive the corresponding stop part 311 to rotate clockwise to move away from the locking part 22, while the other of the two rotating parts 312 will not rotate. Alternatively, the other of the two rotating parts 312 will drive the corresponding stop part 311 to rotate clockwise (i.e., move closer to the locking part 22). In this case, the stop part 311 of the other of the two rotating parts 312 will be blocked by the locking part 22 and will not move away from the locking part 22, thus keeping the locking mechanism 30 in the locked state.

[0122] In this way, by setting the rotation directions of the two rotating parts 312 of the two locking members 31 to opposite directions, accidental unlocking can be prevented, the stability of the front cover lock can be improved, and thus the safety of the vehicle can be enhanced.

[0123] Of course, in some other possible embodiments, the rotating parts 312 of the two locking members 31 rotate in the same direction.

[0124] For example, when the driving member applies a leftward force to one of the two locking members 31, the rotating part 312 of the locking member 31 can rotate clockwise, causing the stop part 311 of the locking member 31 to move away from the locking part 22; when the driving member applies a rightward force to the other of the two locking members 31, the rotating part 312 of the locking member 31 can also rotate clockwise, causing the stop part 311 of the locking member 31 to move away from the locking part 22.

[0125] When the front of the vehicle is subjected to an offset collision, both locking parts 31 will be subjected to a large lateral impact force in the same direction, such as to the left. If the rotation directions of the rotating parts 312 of the two locking parts 31 are the same, then one of the two rotating parts 312 will drive the corresponding stop part 311 to rotate clockwise to move away from the locking part 22, while the other of the two rotating parts 312 will not rotate, or will drive the corresponding stop part 311 to rotate counterclockwise, but will not move away from the locking part 22, so that the locking mechanism 30 remains in the locked state.

[0126] Continue to refer to Figure 4 The locking mechanism 30 also includes two limiting members 32, which are connected to the base 10 and can move relative to the base 10. The two limiting members 32 correspond one-to-one with the two locking members 31.

[0127] For example, the two limiting members 32 can be slidably connected to the base 10. Of course, the two limiting members 32 can also be rotatably connected to the base 10. Alternatively, one limiting member 32 can be slidably connected to the base 10, and the other limiting member 32 can be rotatably connected to the base 10, as long as the limiting member 32 can drive the stop portion 311 of the locking member 31 to move from the side of the locking portion 22 near the front cover to the direction away from the locking portion 22.

[0128] Continue to refer to Figure 5 In some embodiments, the locking member 31 further includes a first limiting part 313, and the limiting member 32 includes a second limiting part 321.

[0129] Continue to refer to Figure 5 and Figure 8 When the locking mechanism 30 is in the locked state, the second limiting part 321 of the limiting member 32 abuts against the first limiting part 313 of the locking member 31 to restrict the movement of the locking member 31; when the locking mechanism 30 is in the unlocked state, the second limiting part 321 of the limiting member 32 separates from the first limiting part 313 of the locking member 31.

[0130] Based on this, this application provides a first limiting part 313 and a second limiting part 321, so that when the first limiting part 313 and the second limiting part 321 are in abutting state, the movement of the locking member 31 can be restricted, thereby making the locking mechanism 30 in a locked state. When the first limiting part 313 and the second limiting part 321 are in a separated state, the stop part 311 of the locking member 31 can move away from the locking part 22, thereby making the locking mechanism 30 in an unlocked state.

[0131] refer to Figure 11 and Figure 12 and combined Figure 5 In some embodiments, the limiting member 32 further includes a rotating part 322, which is rotatably connected to the base 10. The rotation axis of the rotating part 322 is perpendicular to the first direction and perpendicular to the connecting part 21 (see...). Figure 3 ) and locking part 22 (see Figure 3 The second limiting part 321 is connected to the rotating part 322 in the arrangement direction of the ) .

[0132] Based on this, this application provides a rotating part 322. During the process of switching the locking mechanism 30 from the locked state to the unlocked state, when the rotating part 322 rotates along its rotation axis, it can drive the second limiting part 321 to rotate along the rotation axis of the rotating part 322. This allows the second limiting part 321 to drive the first limiting part 313 to rotate along the rotation axis of the rotating part 312, so that the second limiting part 321 and the first limiting part 313 switch from the contact state to the separation state, thereby realizing the switching of the locking mechanism 30 between the locked state and the unlocked state.

[0133] In some possible embodiments, when the locking mechanism 30 is in the unlocked state, the second limiting portion 321 of a limiting member 32 and the first limiting portion 313 of a locking member 31 are still in contact.

[0134] refer to Figure 13 The limiting member 32 and the locking member 31 can slide in the left and right directions, and the first limiting part 313 has a tendency to slide to the right. When the locking mechanism 30 is in the locked state, the second limiting part 321 can abut against the first limiting part 313 to restrict the first limiting part 313 from sliding to the right, so that the stop part 311 of the locking member 31 is located on the side of the locking part 22 closer to the front cover; during the process of the locking mechanism 30 switching from the locked state to the unlocked state, the second limiting part 321 slides to the right, and the first limiting part 313 slides to the right accordingly, so that the stop part 311 of the locking member 31 moves away from the locking part 22 (see Figure 3 This allows the locking mechanism 30 to switch from the locked state to the unlocked state.

[0135] As the first limiting part 313 slides to the right along with the second limiting part 321, the first limiting part 313 can always abut against the second limiting part 321, thereby improving the stability of the limiting member 32 and the locking member 31 during the movement.

[0136] The following embodiments are all illustrated using the locking mechanism 30, which includes two limiting members 32 and two locking members 31.

[0137] Continue to refer to Figure 4 and Figure 5 In some embodiments, the locking mechanism 30 further includes a reset member 33, which is connected to the substrate 11.

[0138] The reset member 33 is connected to at least one of the two limiting members 32, that is, the reset member 33 can be connected to either one of the two limiting members 32 or to both limiting members 32. After the second limiting part 321 separates from the first limiting part 313, the reset member 33 is used to reset the limiting member 32.

[0139] Based on this, this application connects the reset member 33 with the limiting member 32, so that the limiting member 32 can return to its original position after the second limiting part 321 separates from the first limiting part 313, ensuring that when the locking mechanism 30 is in the locking state again, the second limiting part 321 can abut against the first limiting part 313 again to restrict the movement of the locking member 31.

[0140] Continue to refer to Figure 4 , Figure 5 and Figure 8 In other embodiments, the reset member 33 is connected to at least one of the two locking members 31; that is, the reset member 33 may be connected to either one of the two locking members 31 or to both of them. During the switching process of the locking mechanism 30 from the locked state to the unlocked state, the reset member 33 is used to move the stop portion 311 away from the locking portion 22.

[0141] Based on this, this application connects the reset member 33 to the locking member 31, so that the stop part 311 of the locking member 31 can move away from the locking part 22 during the process of the second limit part 321 and the first limit part 313 switching from the contact state to the separation state, so that the locking mechanism 30 switches from the locked state to the unlocked state.

[0142] In this way, when the front cover needs to be opened, the reset member 33 can help to quickly release the lock, making the operation more convenient. When the front cover is closed, the reset member 33 can automatically reset the limit member 32, ensuring that the front cover is locked again. By setting the reset member 33, this application can improve the security, convenience and reliability of the front cover lock, and help ensure the normal operation of the front cover lock and the safety of the user.

[0143] In some other possible embodiments, the reset member 33 may include two sets of motors (not shown in the figure). The output shaft of one set of motors is connected to the limiting member 32, and the rotation axis of the output shaft of this set of motors coincides with the rotation axis of the limiting member 32. When the motor is working, the output shaft will generate rotational motion, thereby driving the limiting member 32 to rotate along its rotation axis, so that the limiting member 32 is reset.

[0144] The output shaft of another set of motors is connected to the locking member 31, and the rotation axis of the output shaft of this set of motors is the same as the rotation axis of the locking member 31. When the motor is working, the output shaft will generate rotational motion, thereby driving the locking member 31 to move along its rotation axis, so that during the process of the locking mechanism 30 switching from the locked state to the unlocked state, the stop part 311 of the locking member 31 moves away from the locking part 22.

[0145] In some other possible embodiments, the reset member 33 may also include a cylinder (not shown in the figure), which may be a linear cylinder or a rotary cylinder, etc. The linear cylinder uses air or hydraulic pressure to push the piston to produce linear motion. When the linear cylinder is connected to the limiting member 32, the limiting member 32 can be slidably reset; when the linear cylinder is connected to the locking member 31, the stop portion 311 of the locking member 31 can slide away from the locking portion 22.

[0146] The rotary cylinder is used to generate rotational motion. When the rotary cylinder is connected to the limiting member 32, the rotary cylinder can drive the limiting member 32 to rotate along its rotation axis so that the limiting member 32 is reset. When the rotary cylinder is connected to the locking member 31, the rotary cylinder can drive the locking member 31 to move along its rotation axis so that during the process of the locking mechanism 30 switching from the locked state to the unlocked state, the stop part 311 of the locking member 31 moves away from the locking part 22.

[0147] Continue to refer to Figure 4 and Figure 10 In some possible embodiments, the reset member 33 may also include two elastic members 331 connected to the substrate 11. One elastic member 331 is connected to a limiting member 32 and a locking member 31, and the other elastic member 331 is connected to another limiting member 32 and another locking member 31.

[0148] Based on this, by connecting an elastic member 331 to a limiting member 32 and a locking member 31 respectively, the limiting member 32 and the corresponding locking member 31 can move relative to each other within a certain range, thereby adjusting the relative position between the limiting member 32 and the corresponding locking member 31 to a certain extent, so that the second limiting part 321 abuts or separates from the first limiting part 313, thereby realizing the switching of the locking mechanism 30 between the locked state and the unlocked state.

[0149] In addition, the elastic element 331 has a certain degree of elasticity and can deform when subjected to external force, thereby playing a role in shock absorption and buffering. Furthermore, using only one elastic element 331 can simplify the structure, save space, and reduce the complexity of assembly.

[0150] For example, the elastic element 331 can be a torsion spring.

[0151] Of course, the reset member 33 may also include four elastic members, two of which are connected to two limiting members 32 respectively, and the other two elastic members are connected to two locking members 31 respectively.

[0152] For example, the elastic element can be a tension spring.

[0153] Continue to refer to Figure 4 and Figure 9 In some embodiments, the locking mechanism 30 further includes a first rotating shaft 341 and a second rotating shaft 342. The substrate 11 is provided with a first positioning hole 1121 and a second positioning hole 1122. Both the first positioning hole 1121 and the second positioning hole 1122 extend along the thickness direction of the substrate 11 and in a direction perpendicular to the thickness direction of the substrate 11 and perpendicular to the arrangement direction of the connecting portion 21 and the locking portion 22 (i.e.,...). Figure 4 The left and right direction (as shown in the figure) are set for the interval.

[0154] The first rotating shaft 341 passes through the first positioning hole 1121, and the second rotating shaft 342 passes through the second positioning hole 1122. The portion of the first rotating shaft 341 located on one side of the substrate 11 is rotatably connected to one of the two limiting members 32, and the portion of the first rotating shaft 341 located on the other side of the substrate 11 is rotatably connected to one of the two locking members 31. The portion of the second rotating shaft 342 located on one side of the substrate 11 is rotatably connected to the other of the two locking members 31, and the portion of the second rotating shaft 342 located on the other side of the substrate 11 is rotatably connected to the other of the two limiting members 32.

[0155] Based on this, by setting the first rotating shaft 341 and the second rotating shaft 342, the limiting member 32 on one side of the substrate 11 and the locking member 31 on the other side of the substrate 11 are coaxially arranged, and the locking member 31 on one side of the substrate 11 and the limiting member 32 on the other side of the substrate 11 are coaxially arranged. This simplifies the structure and also helps to improve space utilization.

[0156] refer to Figure 14 and Figure 15 and combined Figure 4In some embodiments, the reset member 33 includes two torsion springs. One torsion spring has two fixed ends 3311 and two free ends 3312. One fixed end 3311 is sleeved on the portion of the first rotating shaft 341 located on one side of the substrate 11, and the other fixed end 3311 is sleeved on the portion of the second rotating shaft 342 located on one side of the substrate 11. One free end 3312 abuts against the limiting member 32 to reset the limiting member 32, and the other free end 3312 abuts against the locking member 31 to move the stop portion 311 of the locking member 31 away from the locking portion 22.

[0157] Continue to refer to Figure 14 and Figure 15 and combined Figure 9 In some embodiments, the substrate 11 is also provided with a clearance hole 113, so that the free end 3312 of the torsion spring can move in the clearance hole 113, preventing the free end 3312 of the torsion spring from interfering with the substrate 11 during the movement, thereby improving the stability and reliability of the structure.

[0158] For example, the clearance hole 113 is an arc-shaped hole, and the extension direction of the arc-shaped hole is consistent with the movement trajectory of the free end 3312 of the torsion spring, which can effectively prevent the torsion spring from deviating and ensure the accuracy and stability of the movement.

[0159] refer to Figure 16 In some embodiments, the locking mechanism 30 further includes a plurality of snap rings 351.

[0160] Multiple slots 343 are provided at intervals along the axial direction of the first rotating shaft 341. A retaining spring 351 can be inserted into a slot 343. The limiting member 32 and the locking member 31 are respectively located between two adjacent retaining springs 351. The retaining spring 351 is used to restrict the fixed end 3311 of the corresponding limiting member 32, locking member 31 and torsion spring from moving along the axial direction of the first rotating shaft 341.

[0161] Multiple slots 343 are also provided at axial intervals along the second rotating shaft 342. A snap ring 351 can be snapped into a slot 343. The limiting member 32 and the locking member 31 are respectively located between two adjacent snap rings 351. The snap ring 351 is used to restrict the fixed end 3311 of the corresponding limiting member 32, locking member 31 and torsion spring from moving axially along the second rotating shaft 342.

[0162] Based on this, it can be ensured that the limiting member 32 and the locking member 31 can only rotate around the first rotating shaft 341 and the second rotating shaft 342 respectively, thereby realizing the locking and unlocking of the locking mechanism 30.

[0163] Continue to refer to Figure 4In some embodiments, the locking mechanism 30 further includes four reset stops 361 connected to the base 10, wherein two reset stops 361 correspond to two limiters 32 respectively, and the other two reset stops 361 correspond to two locking members 31 respectively.

[0164] After the reset member 33 resets the limiting member 32, the limiting member 32 still has a tendency to move. When the limiting member 32 reaches the reset position, the reset stop member 361 can abut against the limiting member 32 to restrict the movement of the limiting member 32, so that the limiting member 32 remains in the reset state.

[0165] After the reset member 33 moves the stop portion 311 of the locking member 31 away from the locking portion 22, the stop portion 311 of the locking member 31 still has a tendency to move away from the locking portion 22. When the stop portion 311 reaches a certain position, the reset stop member 361 can abut against the locking member 31 to restrict the locking member 31 from continuing to move, so that the locking mechanism 30 can lock again.

[0166] refer to Figure 17 For example, the reset stop 361 may include a first stop shaft 3611 and a second stop shaft 3612.

[0167] Continue to refer to Figure 9 The substrate 11 is provided with a first stop shaft hole 1141 and a second stop shaft hole 1142. Both the first stop shaft hole 1141 and the second stop shaft hole 1142 extend along the thickness direction of the substrate 11 and are spaced apart in a direction perpendicular to the thickness direction of the substrate 11 and perpendicular to the arrangement direction of the connecting part 21 and the locking part 22. The first stop shaft hole 1141 is located on the side of the limiting member 32 away from the locking member 31, and the second stop shaft hole 1142 is located on the side of the locking member 31 away from the limiting member 32.

[0168] Continue to refer to Figure 9 and Figure 17 and combined Figure 4 The first stop shaft 3611 passes through the first stop shaft hole 1141, and the second stop shaft 3612 passes through the second stop shaft hole 1142. The portion of the first stop shaft 3611 located on one side of the substrate 11 is used to abut against a limiting member 32, and the portion of the first stop shaft 3611 located on the other side of the substrate 11 is used to abut against a locking member 31. The portion of the second stop shaft 3612 located on one side of the substrate 11 is used to abut against another locking member 31, and the portion of the second stop shaft 3612 located on the other side of the substrate 11 is used to abut against another limiting member 32.

[0169] Continue to refer to Figure 17 In some embodiments, the reset stop 361 further includes a buffer sleeve 3613 sleeved on the stop shaft.

[0170] Based on this, the buffer bushing 3613 has a buffering effect. When the reset stop 361 abuts against the limiting member 32 or the locking member 31, it can reduce vibration transmission, absorb the impact force of the limiting member 32 or the locking member 31 on the reset stop 361, reduce the noise generated during system operation, and extend the service life.

[0171] For example, the material of the buffer bushing 3613 can be rubber, sponge, etc.

[0172] refer to Figure 18 and Figure 19 In some embodiments, the drive element includes a first cable 41, a second cable 42, and a third cable 43.

[0173] One end of the first cable 41 is connected to a limiting member 32 for pulling the limiting member 32 to move; one end of the second cable 42 is connected to another limiting member 32 for pulling the other limiting member 32 to move; and the third cable 43 is connected to the other ends of both the first cable 41 and the second cable 42 for pulling the first cable 41 and the second cable 42 to move.

[0174] Based on this, this application sets up a first cable 41, a second cable 42, and a third cable 43, so that pulling the third cable 43 can drive the first cable 41 and the second cable 42 to move simultaneously, ensuring the synchronicity of unlocking. In addition, the structure is simple and the cost is low.

[0175] It should be noted that, since the first cable 41 and the second cable 42 are relatively flexible, guide structures, such as guide tubes, can be provided for each of them. The first cable 41 and the second cable 42 each pass through a guide tube to guide their movement, preventing them from bending or getting stuck during movement, which would affect the unlocking of the vehicle's front cover.

[0176] Continue to refer to Figure 4 and combined Figure 18 In some possible embodiments, each limiting member 32 further includes a first mounting portion 323, wherein the first mounting portion 323 of one limiting member 32 is used to mount the first cable 41, and the first mounting portion 323 of the other limiting member 32 is used to mount the second cable 42.

[0177] Based on this, by setting the first mounting part 323, the connection stability between the limiting member 32 and the cable structure can be improved.

[0178] Continue to refer to Figure 4 and combined Figure 18In some possible embodiments, the base 10 edge is also provided with two through holes 115, one through hole 115 for passing through the first cable 41 and the other through hole 115 for passing through the second cable 42.

[0179] Based on this, when the first cable 41 and the second cable 42 are pulled, the portion of the first cable 41 located on the base 10 and the portion of the second cable 42 located on the base 10 can move between the first mounting part 323 and the through hole 115, thereby limiting the deviation of the first cable 41 and the second cable 42 from the movement trajectory to a certain extent and ensuring the stability of the cable structure during movement.

[0180] For example, the shape and size of the perforation 115 can be set as needed. The shape of the perforation 115 can be circular, elliptical, arc-shaped or irregular, etc. The radial dimension of the perforation 115 can be greater than or equal to the radial dimension of the cable. The axial dimension of the perforation 115 can be any size, as long as it ensures that the first cable 41 and the second cable 42 can move smoothly along the axial direction of the perforation 115.

[0181] Continue to refer to Figure 18 In some embodiments, the drive unit also includes a junction box 44 and a slider 45.

[0182] Among them, reference Figure 20 and combined Figure 18 The junction box 44 has a receiving cavity 4411. The slider 45 is located in the receiving cavity 4411 and can slide in the receiving cavity 4411. Along the sliding direction of the slider 45, one end of the slider 45 is connected to the other end of the first cable 41 and the other end of the second cable 42, and the other end of the slider 45 is connected to the third cable 43.

[0183] Based on this, this application sets up a junction box 44 and a slider 45, so that while the third cable 43 pulls the slider 45, it can simultaneously pull the first cable 41 and the second cable 42. Furthermore, the receiving cavity 4411 has a guiding function, which can ensure that the slider 45 slides along a defined path, thereby improving the reliability of the drive component.

[0184] refer to Figure 21 In some embodiments, the junction box 44 includes a box body 441 and a cover (not shown in the figure). The box body 441 includes a receiving cavity 4411 and an opening communicating with the receiving cavity 4411. The cover is used to open and close the opening.

[0185] Based on this, the cover can protect the box 441 and the slider 45 inside the box 441, preventing other components from falling into the box 441 due to other external forces and hindering the movement of the slider 45, thereby ensuring the normal operation of the drive component.

[0186] Continue to refer to Figure 21 In some possible embodiments, at least one of the two sidewalls D of the slider 45 abuts against the two sidewalls E of the receiving cavity 4411 in a direction perpendicular to the sliding direction of the slider 45, so that when the slider 45 slides, at least one sidewall D of the slider 45 can slide along the corresponding sidewall E of the receiving cavity 4411, thereby ensuring that the slider 45 can slide along a specific trajectory and improving the stability of the slider 45 during the sliding process.

[0187] In some other possible embodiments, one of the receiving cavity 4411 of the junction box 44 and the slider 45 is provided with a groove (not shown in the figure), and the other is provided with a slide rail (not shown in the figure). The slide rail can slide along the groove, so that the slider 45 can move in the receiving cavity 4411.

[0188] Based on this, the slide rail can effectively prevent deviation when moving in the slide groove, ensuring the accuracy and stability of the movement.

[0189] Continue to refer to Figure 18 and Figure 21 The slider 45 is provided with a first through hole 451, a second through hole 452 and a third through hole 453. The first through hole 451 and the second through hole 452 are located on the side of the slider 45 closer to the first cable 41 and the second cable 42, and the third through hole 453 is located on the side of the slider 45 away from the first cable 41 and the second cable 42.

[0190] The junction box 44 is provided with a first wire hole 4412, a second wire hole 4413, and a third wire hole 4414. The first wire hole 4412 and the second wire hole 4413 are located on the side of the junction box 44 closer to the first cable 41 and the second cable 42, and the third wire hole 4414 is located on the side of the junction box 44 away from the first cable 41 and the second cable 42.

[0191] refer to Figure 22 In some possible embodiments, the first cable 41 includes a first core wire 411 and a first sheath 412 sleeved on the first core wire 411. The first sheath 412 is used to protect the first core wire 411, and the first core wire 411 can move within the first sheath 412.

[0192] One end of the first core wire 411 is installed in the first mounting part 323 of the corresponding limiting member 32, and the other end is installed in the first through hole 451. One end of the first sheath 412 is installed in the corresponding through hole 115, and the other end is installed in the first wire hole 4412.

[0193] Continue to refer to Figure 22In some possible embodiments, the second cable 42 includes a second core wire 421 and a second sheath 422 sleeved on the second core wire 421. The second sheath 422 is used to protect the second core wire 421, and the second core wire 421 can move within the second sheath 422.

[0194] One end of the second core wire 421 is installed in the first mounting part 323 of the corresponding limiting member 32, and the other end is installed in the second through hole 452. One end of the second sheath 422 is installed in the corresponding through hole 115, and the other end is installed in the second wire hole 4413.

[0195] Continue to refer to Figure 22 In some possible embodiments, the third cable 43 includes a third core wire 431 and a third sheath 432 sleeved on the third core wire 431. The third sheath 432 is used to protect the third core wire 431, and the third core wire 431 can move within the third sheath 432.

[0196] Among them, one end of the third core wire 431 is installed in the third through hole 453, and the other end is the pull end; one end of the third sheath 432 is installed in the third wire hole 4414.

[0197] Based on this, when the pulling end of the third core wire 431 is pulled in a certain direction, the third core wire 431 will slide along the receiving cavity 4411 with the slider 45, thereby driving the first core wire 411 and the second core wire 421 to move. The first core wire 411 and the second core wire 421 can simultaneously provide opposite forces to the corresponding limiting member 32, thereby realizing the switching of the locking mechanism 30 from the locked state to the unlocked state.

[0198] Continue to refer to Figure 9 In some embodiments, the two edge sides of the base 10 are also provided with limiting surfaces 116, and the two limiting surfaces 116 correspond to the two through holes 115 respectively.

[0199] Continue to refer to Figure 11 and Figure 12 The limiting member 32 also includes a limiting end 324, which is connected to the rotating part 312.

[0200] Continue to refer to Figure 5 , Figure 11 and Figure 18 When the first cable 41 is pulled, the limiting end 324 on the corresponding limiting member 32 can rotate along its rotation axis with the rotating part 312 until the limiting end 324 abuts against the corresponding limiting surface 116. At this time, the second limiting part 321 of the limiting member 32 separates from the corresponding first limiting part 313, and the stop part 311 of the corresponding locking member 31 (see...) Figure 6 ) can be moved away from the locking part 22 (see Figure 3 ).

[0201] Continue to refer to Figure 5 , Figure 12 and Figure 18 When the second cable 42 is pulled, the limiting end 324 on the corresponding limiting member 32 can rotate along its rotation axis with the rotating part 312 until the limiting end 324 abuts against the corresponding limiting surface 116. At this time, the second limiting part 321 of the limiting member 32 separates from the corresponding first limiting part 313, and the stop part 311 of the corresponding locking member 31 (see...) Figure 7 ) can be moved away from the locking part 22 (see Figure 3 ).

[0202] Based on this, the limiting end 324 is limited by the limiting surface 116 provided on the edge side of the base 10, so that the limiting surface 116 and the limiting end 324 are in surface contact, which is beneficial to improving the stability of the limiting member 32 during the movement.

[0203] In related technologies, the free end 3312 of the torsion spring is limited by the two ends of the clearance hole 113 along its extension direction. When the outer wall of the torsion spring contacts the two ends of the clearance hole 113, frictional noise or abnormal sound may be generated due to the frictional force, thereby affecting the normal operation of the equipment.

[0204] This application limits the limiting end 324 by setting the limiting surface 116, which can improve the stability of the limiting part 32 during the movement process, and also prevent the outer wall of the torsion spring from contacting the two ends of the clearance hole 113, thereby helping to reduce wear and noise.

[0205] Continue to refer to Figures 5 to 7 In some embodiments, the stop portion 311 includes a first sub-stop portion 3111 and a second sub-stop portion 3112. When the locking mechanism 30 is in the unlocked state, for any one of the locking members 31, the first sub-stop portion 3111 is located on the side of the second sub-stop portion 3112 closer to the locking portion 22.

[0206] refer to Figure 23 and combined Figure 5 When the locking mechanism 30 is in the locked state, the locking part 22 abuts against the second sub-stops 3112 of the two locking members 31.

[0207] refer to Figure 24 and Figure 25 The locking mechanism 30 also has a semi-locked state. When the locking mechanism 30 is in the semi-locked state, the locking part 22 abuts against the first sub-stop part 3111 of the two locking members 31.

[0208] Based on this, this application sets a first sub-stop 3111 and a second sub-stop 3112, so that the locking mechanism 30 has a locked state and a semi-locked state, which can prevent the front cover from being unlocked prematurely due to misoperation, thereby improving the reliability and security of the front cover lock.

[0209] Continue to refer to Figure 24 In some embodiments, the locking member 31 further includes a third limiting portion 314. When the locking mechanism 30 is in a semi-locked state, the second limiting portion 321 of one limiting member 32 abuts against the third limiting portion 314 of one locking member 31 to restrict the movement of one locking member 31; the second limiting portion 321 of another limiting member 32 abuts against the third limiting portion 314 of another locking member 31 to restrict the movement of the other locking member 31.

[0210] Based on this, this application provides a third limiting part 314, which restricts the movement of the locking member 31 when the third limiting part 314 abuts against the second limiting part 321, so that the locking mechanism 30 is in a semi-locked state.

[0211] The following section uses the locking mechanism 30 located on one side of the base 10 as an example to introduce the movement principle of the front cover lock, starting with the unlocking principle.

[0212] Continue to refer to Figure 5 , Figures 23 to 25 When the locking mechanism 30 is in the locked state, the second limiting part 321 of the limiting member 32 abuts against the first limiting part 313 of the locking member 31; pulling the first cable 41 to the left causes the limiting member 32 to rotate clockwise, and the second limiting part 321 and the first limiting part 313 move from the abutting state to the separated state. During this process, the locking member 31 rotates counterclockwise until the second limiting part 321 and the first limiting part 313 are completely separated, and the locking member 31 is reset by the reset member 33. Under the action of the locking member 31, the second sub-stop 3112 of the locking member 31 and the locking part 22 of the locking pin 20 are switched from the contact state to the separation state. At the same time, the first sub-stop 3111 and the locking part 22 are in contact, and the third limiting part 314 of the locking member 31 is in contact with the second limiting part 321. Thus, the locking mechanism 30 is switched from the locked state to the semi-locked state. After the second limiting part 321 and the first limiting part 313 are separated, the limiting member 32 is reset under the action of the reset member 33.

[0213] Continue to refer to Figure 8 , Figures 24 to 26When the locking mechanism 30 is in a semi-locked state, the first cable 41 is pulled to the left again, thereby causing the limiting member 32 to rotate clockwise. The second limiting part 321 and the third limiting part 314 move from the contact state to the separation state. During this process, the locking member 31 rotates counterclockwise until the second limiting part 321 and the third limiting part 314 are completely separated. Under the action of the reset member 33, the locking member 31 rotates clockwise, so that the first sub-stop part 3111 of the locking member 31 and the locking part 22 of the locking pin 20 switch from the contact state to the separation state. Thus, the locking mechanism 30 switches from the semi-locked state to the unlocked state. After the second limiting part 321 and the third limiting part 314 separate, the limiting member 32 is reset under the action of the reset member 33.

[0214] The unlocking principle of the portion of the locking mechanism 30 located on the other side of the base 10 is the same as the unlocking principle described above, and will not be repeated here. It should be noted that when unlocking the portion of the locking mechanism 30 located on the other side of the base 10, the second cable 42 needs to be pulled to the right to achieve bidirectional engagement and unlocking, thereby improving the security and reliability of the front cover lock.

[0215] Secondly, regarding the locking principle, pressing down on the front cover allows the front cover's own weight and the pressure acting on it to overcome the torque of the front cover lock's reset component 33, enabling the locking mechanism 30 to automatically enter the locking state. The locking process is existing technology and will not be described in detail here.

[0216] refer to Figure 27 and combined Figure 24 In some embodiments, the front cover lock also includes a trigger warning element 50 connected to the base 10 for alerting the user that the front cover is in the open state.

[0217] Continue to refer to Figures 25 to 27 The trigger warning element 50 includes a trigger spring 51, and the front hood lock also includes a controller (not shown) and a warning element (not shown). The controller is electrically connected to both the warning element and the trigger spring 51. The locking element 31 also includes a trigger part 315. When the locking mechanism 30 is in a semi-locked or unlocked state, the trigger part 315 abuts against the trigger spring 51, causing the controller to receive a signal and send it to the warning element. The warning element then alerts the user that the front hood is currently open and poses a certain risk.

[0218] For example, the triggering alarm element 50 can be a proximity switch.

[0219] For example, the prompting device can be an indicator light, a vehicle display screen, a terminal device, etc.

[0220] refer to Figure 28 and combined Figure 9The triggering alarm element 50 also includes a second mounting part 52, and the base 10 also includes a third mounting part 117. The second mounting part 52 can be mounted on the third mounting part 117 so that the triggering alarm element 50 is mounted on the base 10.

[0221] For example, the second mounting part 52 can be the first connecting hole, and the third mounting part 117 can be the second connecting hole. Fasteners are used to pass through the first connecting hole and the second connecting hole to fix the second mounting part 52 and the third mounting part 117.

[0222] Continue to refer to Figure 9 and Figure 28 For example, the second mounting part 52 can be a mounting boss, and the third mounting part 117 can be a mounting hole. The mounting boss can be inserted into the mounting hole to mount the second mounting part 52 onto the third mounting part 117.

[0223] This application also provides a vehicle that includes the aforementioned front hood lock.

[0224] Based on this, this application uses the aforementioned front hood lock in the vehicle so that the locking mechanism 30 remains locked when the vehicle is subjected to an offset collision, thereby keeping the front hood closed and improving the safety of the vehicle and the user.

[0225] This application also provides a control method for a front cover lock, applied to the aforementioned front cover lock, the control method comprising:

[0226] refer to Figure 29 When a command to unlock the front cover is received, the control drive applies opposite forces to the stop portions 311 of the two locking members 31, so that the stop portions 311 of the two locking members 31 move away from the locking portion 22, thereby switching the locking mechanism 30 from the locked state to the unlocked state.

[0227] The control pin 20 moves away from the locking mechanism 30 along the front cover of the vehicle so as to separate the locking pin 20 from the locking mechanism 30.

[0228] Based on this, drivers and passengers only need to control the drive components to unlock the vehicle's front hood, and the front hood lock will not be opened due to external forces on the vehicle, thus improving the vehicle's reliability.

[0229] In some embodiments, the control method further includes:

[0230] refer to Figure 30 When a command to close the front hood lock is received, the control lock pin 20 moves along the front hood toward the locking mechanism 30, so that the locking part 22 moves between the two locking parts 31.

[0231] The stop portion 311 of the two locking parts 31 is moved to the side of the locking part 22 near the front cover, so that the locking mechanism 30 is switched from the unlocked state to the locked state.

[0232] Based on this, drivers and passengers only need to control the drive components to open and close the vehicle's front hood lock, which improves the comfort of driving and passenger use through simplified operation.

[0233] Furthermore, when the vehicle is involved in a misaligned collision, no opening or closing command is generated. The force exerted on the vehicle by the misaligned collision is a unidirectional force, which will not exert opposite forces on the stop portions 311 of the two locking parts 31. This prevents the front hood lock from accidentally opening when the vehicle is involved in a misaligned collision, improves the reliability of the front hood lock structure, and further enhances the safety and stability of the vehicle.

[0234] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
