DETAILED DESCRIPTION

[0032] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0034] The hood lock 100 according to an embodiment of the present application will be described in detail below with reference to FIG. 1 to FIG. 8 .

[0035] 1 and 4 , the hood lock 100 according to an embodiment of the present application includes a mounting plate 1 , a lock tongue 10 , a locking arm 7 , an attraction push arm 16 and an attraction arm 22 .

[0036] The lock tongue 10 is installed on the mounting plate 1, and the lock tongue 10 can pivot relative to the mounting plate 1; the locking arm 7 is installed on the mounting plate 1, and the locking arm 7 can pivot relative to the mounting plate 1; the suction push arm 16 is installed on the mounting plate 1, and the suction push arm 16 can pivot relative to the mounting plate 1; the suction arm 22 is installed on the suction push arm 16, and when the suction push arm 16 rotates, it can drive the suction arm 22 to move.

[0037] When the engaging arm 22 moves, the engaging arm 22 can push the lock tongue 10 to rotate, and the lock tongue 10 can lock with the locking arm 7, so that the lock tongue 10 is in the locked position and the hood lock 100 is locked. When the locking arm 7 separates from the lock tongue 10, the lock tongue 10 can rotate under the action of the lock tongue reset member 12, and the lock tongue 10 can rotate to the unlocked position under the action of the lock tongue reset member 12, and the hood lock 100 is unlocked. It should be noted that during the process of the lock tongue 10 rotating to the unlocked position, the engaging arm 22 separates from the lock tongue 10 to prevent the engaging arm 22 from obstructing the rotation of the lock tongue 10.

[0038] In the prior art, hood locks require the coordination of several components, including a pull-in connecting rod, a pull-in transition rod, a pull-in connecting rod, an eccentric spring, a transition rod torsion spring, and transition rod rivets, to achieve a locking function. In the present application, the locking function is achieved solely through the coordination of the lock tongue 10, the lock tongue reset member 12, the locking arm 7, and the pull-in arm 22, reducing the number of components and simplifying the internal structure of the hood lock 100.

[0039] According to the hood lock 100 of the embodiment of the present application, the rotation of the suction push arm 16 can drive the suction arm 22 to move. When the suction arm 22 moves, it pushes the lock tongue 10 to rotate, so that the lock tongue 10 and the locking arm 7 are locked and matched, thereby achieving the locking of the lock tongue 10 position, thereby achieving the locking of the hood lock 100; and through the separation of the lock tongue 10 and the locking arm 7 and the action of the lock tongue reset member 12, the position of the lock tongue 10 is unlocked, thereby achieving the unlocking of the hood lock 100. The hood lock 100 of the present application has a simple structure. Through the cooperation between the lock tongue 10, the lock tongue reset member 12, the suction push arm 16 and the suction arm 22, the hood lock 100 can be locked and unlocked, which simplifies the internal structure of the hood lock 100 and is easy to manufacture and assemble.

[0040] 4 , for example, the suction arm 22 includes a suction arm suction structure 24, and the lock tongue 10 includes a lock tongue suction structure 23. The suction arm 22 and the lock tongue 10 are suctioned, specifically, the suction arm suction structure 24 and the lock tongue suction structure 23 are suctioned.

[0041] Optionally, the attraction arm attraction structure 24 and the lock tongue attraction structure 23 may be magnetically attracted.

[0042] Optionally, the suction arm 22 can abut against the lock tongue 10 to push the lock tongue 10 to rotate when the suction arm 22 rotates. The area on the suction arm 22 that abuts against the lock tongue 10 is the suction arm suction structure 24, and the area on the lock tongue 10 that abuts against the suction arm 22 is the lock tongue suction structure 23.

[0043] As shown in Figures 1 and 2, for example, the front hood lock 100 includes a mounting plate 1 and a fixing plate 6. The fixing plate 6 can be covered on the mounting plate 1. There is an installation space between the fixing plate 6 and the mounting plate 1, and the lock tongue 10, the locking arm 7, and the suction arm 22 can be installed.

[0044] As shown in Figures 5 and 6, in some embodiments, the locking arm 7 is pivotally connected to the mounting plate 1 at the first pivot axis 8, and the suction push arm 16 is pivotally connected to the mounting plate 1 at the second pivot axis 17. One end of the suction arm 22 is connected to the third pivot axis 19, and the suction arm 22 can pivot relative to the third pivot axis 19. The suction arm 22 is connected to the suction push arm 16 at the third pivot axis 19, and the other end of the suction arm 22 is provided with a release pin 21. A limiting groove 25 is provided on the mounting plate 1 and / or the fixed plate 6. When the suction push arm 16 rotates in the second direction (counterclockwise as shown in Figure 5), the suction push arm 16 drives the suction arm 22 to rotate in the first direction (clockwise as shown in Figure 5), so that the release pin 21 can move along the limiting groove 25. By installing the suction arm 22 at the third pivot axis 19 and connecting it to the suction push arm 16, the suction arm 22 can move under the action of the suction push arm 16, and the suction arm 22 can pivot relative to the suction push arm 16, and can move when the suction push arm 16 pivots relative to the second pivot axis 17, so that the suction arm 22 can make planar motion; by setting the release pin 21 to move along the limit slot 25, the suction arm 22 can move along a predetermined route to avoid taking the wrong route, thereby improving the reliability of the front hood lock 100.

[0045] It is understood that one of the first direction and the second direction is clockwise and the other is counterclockwise. For example, the first direction is clockwise and the second direction is counterclockwise; for another example, the first direction is counterclockwise and the second direction is clockwise. In the examples of Figures 2-7, the first direction is clockwise and the second direction is counterclockwise.

[0046] As shown in FIG. 4 and FIG. 7 , for example, the locking arm 7 is connected to the first pivot shaft 8 via a locking arm pin, whereby the locking arm 7 can rotate around the locking arm pin.

[0047] Optionally, a limiting groove 25 can be provided on the mounting plate 1 , and the limiting groove 25 is constructed as a groove formed on the mounting plate 1 along the thickness direction, and the release pin 21 can partially extend into the groove, and the groove wall of the groove provides support force to the release pin 21, so that the release pin 21 can move along the limiting groove 25 .

[0048] As shown in Figures 1 and 2, for example, the limiting groove 25 can be set on the fixed plate 6. In other words, an opening is formed on the fixed plate 6 along the limiting groove 25 in the thickness direction, and the release pin 21 can partially extend into the opening. The hole wall of the opening forms the limiting groove 25, and the hole wall of the opening provides support force to the release pin 21, so that the release pin 21 can move along the limiting groove 25.

[0049] For example, the suction push arm 16 is connected to the second pivot axis 17 by a suction push arm pin, so that the suction push arm 16 can rotate around the suction push arm pin. The suction arm pin is arranged at the third pivot axis 19, and the suction arm pin is connected to the suction push arm 16, so that the suction arm 22 can rotate around the suction arm pin.

[0050] As shown in FIG5 and FIG6 , in some embodiments, the hood lock 100 further includes an engagement drive mechanism that can drive the engagement push arm 16 to rotate the engagement push arm 16 in a second direction. When the engagement push arm 16 rotates in the second direction, the engagement push arm 16 drives the engagement arm 22 to rotate in the first direction (i.e., clockwise), and the engagement push arm 16 causes the release pin 21 to move along the limiting groove 25. By providing the engagement drive mechanism to drive the engagement push arm 16, the hood lock 100 can be electrically engaged, thereby reducing manpower and improving the convenience of locking the hood lock 100.

[0051] As shown in Figures 4-6, in some embodiments, the hood lock 100 further includes a pull cable 4, through which the pull cable 4 connects the pull drive mechanism and the pull push arm 16. This design can streamline the structure while improving the stability of the connection between the electric pull drive mechanism and the pull push arm 16. Optionally, the pull drive mechanism can be an electric pull drive motor.

[0052] As shown in Figure 4, in some embodiments, the locking arm 7 includes a locking arm body and a latching structure 13, which is connected to the locking arm body. The locking arm body is pivotally mounted to the mounting plate 1. The lock tongue 10 includes a lock tongue body and a latching structure 14, which is pivotally mounted to the mounting plate 1. The latching structure 14 is disposed on the lock tongue body and can engage or disengage with the latching structure 13. This allows the hood lock 100 to be locked and unlocked, simplifying the structure of the hood lock 100.

[0053] In some embodiments, the lock tongue 10 includes a lock tongue body and a lock tongue suction structure 23. The lock tongue body is pivotally mounted on the mounting plate 1. The lock tongue suction structure 23 is disposed on the lock tongue body. The suction arm 22 can be attracted to or separated from the lock tongue suction structure 23. Specifically, the suction arm suction structure 24 of the suction arm 22 can be attracted to or separated from the lock tongue suction structure 23. As shown in Figures 3 and 4, specifically, when the suction arm suction structure 24 is attracted to the lock tongue suction structure 23, the lock tongue 10 rotates under the push of the suction arm 22, and the lock tongue 10 can rotate counterclockwise until the tongue structure 14 and the locking structure 13 are locked. When the suction arm suction structure 24 and the lock tongue suction structure 23 are separated, the lock tongue 10 can rotate under the action of the lock tongue reset member 12, and the lock tongue 10 rotates clockwise to an unlocked position where the tongue structure 14 and the locking structure 13 are separated.

[0054] As shown in FIG. 4 , for example, the lock tongue 10 is mounted on the mounting plate 1 via a lock tongue pin 11 , and the lock tongue 10 can rotate around the axis of the lock tongue pin 11 .

[0055] As shown in Figures 3 and 4, in some embodiments, the tongue structure 14 includes a first tongue structure 141 and a second tongue structure 142, which are spaced apart along the rotation direction of the lock tongue 10. The hood lock 100 has a semi-locked state and a fully locked state. When the hood lock 100 is in the semi-locked state, the locking structure 13 is locked with the second tongue structure 142; when the hood lock is in the fully locked state, the locking structure 13 is locked with the first tongue structure 141. When the locking arm 7 and the lock tongue 10 are unlocked, the lock tongue 10 rotates clockwise as the locking arm 7 rotates clockwise, and the latch structure 13 sequentially unlocks the first latch structure 141 and the second latch structure 142. When the engagement arm 22 and the lock tongue 10 are engaged, the engagement arm 22 rotates clockwise as the lock tongue 10 rotates counterclockwise, and the latch structure 13 sequentially locks with the second latch structure 142 and the first latch structure 141, thereby changing the hood lock 100 from a partially locked state to a fully locked state. By providing the first latch structure 141 and the second latch structure 142, the multiple latch structures 14 can improve the reliability of the hood lock 100, thereby enhancing the anti-theft and safety performance of the vehicle 200. As shown in FIG4 , in some embodiments, the hood lock 100 further includes an unlocking drive mechanism for driving the locking arm 7 to rotate in a first direction (i.e., clockwise) to separate the latch structure 13 from the latch structure 14. By providing the unlocking drive mechanism, the front hood lock 100 can be electrically unlocked, which reduces manpower and improves the convenience of unlocking.

[0056] As shown in Figure 4, in some embodiments, the hood lock 100 further includes an unlocking cable 3, through which the unlocking drive mechanism and the locking arm 7 are connected. This design can streamline the structure while improving the stability of the connection between the electrolytic drive mechanism and the locking arm 7. Optionally, the unlocking drive mechanism is an electrolytic drive motor.

[0057] As shown in Figure 4 , for example, the unlocking cable 3 includes an unlocking cable structure 15, which connects the locking arm 7 and the unlocking cable 3, improving the stability of the connection. The unlocking cable structure 15 can be connected to the unlocking cable 3 and embedded in the locking arm 7. Optionally, the unlocking cable structure 15 can be configured as a straight segment or a ball head structure.

[0058] Optionally, a mechanical cable 2 may be provided on the locking arm 7 , and the mechanical cable 2 is integrated with the unlocking cable 3 , so that both manual unlocking and electric unlocking functions can be realized through the locking arm 7 .

[0059] As shown in Figures 2 to 7, in some embodiments, the locking arm 7 is pre-tightened and fixed to the mounting plate 1 by the locking arm spring 9, the suction arm 22 is pre-tightened and fixed to the suction push arm 16 by the suction arm spring 20, and the suction push arm 16 is pre-tightened and fixed to the mounting plate 1 by the suction push arm spring 18. As a result, the locking arm 7 can automatically return to the locked position under the action of the locking arm spring 9, thereby achieving the fixation of the locking arm 7 in the locked state and improving the locking stability. The same applies to the suction arm spring 20 and the suction push arm spring 18.

[0060] As shown in FIG. 2 to FIG. 7 , for example, the locking arm spring 9 may be provided on the locking arm pin, the attracting arm spring 20 may be provided on the attracting arm pin, and the attracting push arm spring 18 may be provided on the attracting push arm pin.

[0061] In some embodiments, the limiting groove 25 is a full-circle annular groove formed on the mounting plate 1 and / or the fixed plate 6. For example, the limiting groove 25 is a full-circle annular groove formed on the mounting plate 1, or the limiting groove 25 is a full-circle annular groove formed on the fixed plate 6, or the limiting groove 25 is a full-circle annular groove formed on the mounting plate 1 and the fixed plate 6. By providing an opening on the mounting plate 1 and / or the fixed plate 6 that matches the motion trajectory of the release pin 21, the motion range of the suction arm 22 is limited by the cooperation between the opening and the release pin 21. By providing the opening as a full-circle annular groove structure, the reliability of the unlocking cable and the suction cable can be improved.

[0062] 1 to 8 , a front hood lock 100 according to a specific embodiment of the present application will be described below.

[0063] The front hood lock 100 includes a mounting plate 1 , a fixing plate 6 , an unlocking cable 3 , and a closing cable 4 .

[0064] The suction cable 4 is installed inside the front cabin of the vehicle body through the mounting plate 1. Referring to Figures 1 and 4, the locking arm pin is riveted to the first pivot shaft 8 of the mounting plate 1 by riveting, and the lock tongue pin 11 is riveted on the mounting plate 1. The locking arm 7 is fixed by the shoulder of the locking arm pin, and the lock tongue 10 is fixed by the shoulder of the lock tongue pin 11. The locking arm spring 9 pre-tightens the locking arm 7, and the lock tongue spring 12 pre-tightens the lock tongue 10.

[0065] When the front hood lock 100 needs to be electrically unlocked, the electrolytic drive structure moves to the left by pulling the unlocking cable 3, and the unlocking cable 3 and the locking arm 7 are fixed by the unlocking cable structure 15. The unlocking cable 3 drives the locking arm 7 to rotate clockwise, that is, the locking structure 13 rotates clockwise. When it rotates to a certain angle, the locking structure 13 and the tongue structure 14 are disengaged, and the lock tongue 10 rotates clockwise to the unlocking position under the action of the lock tongue reset member 12, thereby completing the electric unlocking function.

[0066] The electric engagement of the hood lock 100 is shown in Figures 4, 5, and 6. An engagement structure is added to the previously described electric unlocking structure. As shown in Figures 4 and 5, the engagement push arm pin is riveted to the second pivot axis 17 of the mounting plate 1. The engagement push arm 16 is secured via the engagement push arm pin shoulder. The engagement push arm 16 and the engagement arm 22 are riveted together via the engagement arm pin, which is located at the third pivot axis 19. The engagement push arm spring 18 pre-tightens the engagement push arm 16, while the engagement arm spring 20 pre-tightens the engagement arm 22. The release pin 21 is pre-tightened against the limit slot 25 of the fixed plate 6 by the engagement arm spring 20.

[0067] When electric suction is required, as shown in Figures 5 and 6, the suction drive mechanism pulls the suction cable 4 to make the suction push arm 16 move counterclockwise, and drives the suction arm 22 to move upward through the suction arm pin located on the third pivot shaft 19. Figure 6 shows the movement to the initial engagement position. The suction cable 4 is continued to be pulled to make the suction arm 22 continue to move upward along the limit groove 25 (on the fixed plate 6). The lock tongue suction structure 23 and the suction arm suction structure 24 are abutted to make the lock tongue 10 rotate counterclockwise until locking is completed, completing the electric suction function.

[0068] As shown in Figures 6 and 7, the hood lock 100 according to an embodiment of the present application further includes an emergency release arm and a mechanical cable 2. The emergency release arm is mounted on the mounting plate 1 and is pivotable relative to the mounting plate 1. The mechanical cable 2 is connected to the emergency release arm and can pull the emergency release arm, causing it to rotate. This allows the emergency release arm to push the engagement arm 22 away from the lock tongue 10, and the emergency release arm to push the locking arm 7 away from the lock tongue 10. The lock tongue 10 can then rotate under the action of the lock tongue reset member 12, rotating to the unlocked position to achieve emergency release. The emergency release arm includes a control arm 27 and an emergency release arm 28. The control arm 27 is mounted on the mounting plate 1 and is pivotable relative to the mounting plate 1; the emergency release arm 28 is mounted on the mounting plate 1 and is pivotable relative to the mounting plate 1. The mechanical cable 2 is connected to the control arm 27. The mechanical cable 2 can pull the control arm 27 to rotate in a first direction, where the first direction is the clockwise direction as shown in Figures 2 and 7. When the control arm 27 rotates in the clockwise direction, the control arm 27 can drive the emergency release arm 28 to rotate in the clockwise direction, so that the emergency release arm 28 pushes the suction arm 22 to rotate clockwise, so that the suction arm 22 is separated from the lock tongue 10. The control arm 27 can drive the locking arm 7 to rotate in the clockwise direction, and the control arm 27 drives the locking arm 7 to separate from the lock tongue 10. The mechanical cable 2 is connected to the control arm 27 through the emergency release cable structure 32. Thus, the mechanical cable 2 can pull the control arm 27 to rotate. The emergency release cable structure 32 can be connected to the mechanical cable 2 and embedded in the control arm 27.

[0069] The locking arm 7 is pivotally connected to the mounting plate 1 at the first pivot axis 8, and the control arm 27 is also pivotally connected to the mounting plate 1 at the first pivot axis 8. During emergency unlocking, the control arm 27 rotates clockwise along the emergency unlocking path of the control arm 27, and the locking arm 7 is located along the emergency unlocking path of the control arm 27. Therefore, when the mechanical cable 2 pulls the control arm 27 clockwise, the control arm 27 rotates along the emergency unlocking path, that is, the control arm 27 can drive the locking arm 7 to rotate clockwise.

[0070] As shown in Figures 4 and 7, the locking arm pin and the control arm pin are both mounted on the first pivot shaft 8. Optionally, the locking arm pin and the control arm pin can be integrated into the same pin structure.

[0071] 4 and 7 , specifically, the emergency unlocking path of the control arm 27 is a path in which the control arm 27 rotates clockwise around the control arm pin.

[0072] As shown in FIG7 , in some embodiments, a guide slot 33 is provided on the emergency release arm 28, and a guide pin 29 is provided on the control arm 27. The guide pin 29 is disposed within the guide slot 33 and is movable along the walls of the guide slot 33. Thus, when the control arm 27 rotates clockwise, the guide pin 29 on the control arm 27 also rotates clockwise, abutting against the walls of the guide slot 33. The control arm 27 is connected via the guide pin 29 and pushes the emergency release arm 28 to move, i.e., the emergency release arm 28 can be linked to the control arm 27. For example, when the mechanical cable 2 is pulled outward, the control arm 27 rotates clockwise, driving the guide pin 29 to slide within the guide slot 33, thereby driving the emergency release arm 28 to rotate clockwise.

[0073] The emergency release arm 28 is pivotally connected to the mounting plate 1 at the second pivot axis 17. The emergency release arm 28 includes an emergency release arm disengagement structure 31. The emergency release arm disengagement structure 31 can abut and cooperate with the release pin 21. When the emergency release arm 28 rotates in the first direction, the emergency release arm disengagement structure 31 can push the release pin 21 to move, thereby driving the suction arm 22 to move. The suction push arm pin and the emergency release arm pin can be integrated into a single pin structure.

[0074] The emergency release arm 28 is preloaded and secured to the mounting plate 1 by an emergency release arm spring 30. Consequently, the emergency release arm 28 automatically returns to the locked position under the action of the emergency release arm spring 30, securing the emergency release arm 28 in the locked state. The control arm spring 26 can be mounted on the control arm pin, while the emergency release arm spring 30 is mounted on the emergency release arm pin.

[0075] When emergency opening of the front hood lock 100 is required, as shown in Figures 6 and 7, an electric engagement emergency disengagement structure is added to the aforementioned electric unlocking and electric engagement structures. As shown in Figure 7, the control arm 27 is fixed by the shoulder of the locking arm pin. The control arm 7 is also installed at the first pivot axis 8, and the locking arm pin is riveted to the fixed plate 6. One end of the guide pin 29 is fixed to the control arm 27 by riveting, and the other end of the guide pin 29 is inserted into the guide groove 33, allowing the guide pin 29 to slide within the guide groove 33. The emergency disengagement arm 28 is fixed by the shoulder of the engagement push arm pin. The engagement push arm pin is set at the second pivot axis 17, and the engagement push arm pin is riveted to the fixed plate 6. The control arm spring 26 pre-tightens the control arm 27, and the emergency disengagement arm spring 30 pre-tightens the emergency disengagement arm 28.

[0076] The mechanical cable 2 is fixed by the emergency release cable structure 32. The control arm 27 is required to be on the right side of the locking arm 7 at the emergency release cable structure 32. Such an arrangement can achieve: when mechanical unlocking or emergency release is performed, the control arm 27 drives the locking arm 7 to move, and when electrical unlocking is performed, only the unlocking cable 3 drives the locking arm 7 to move while the control arm 27 does not move.

[0077] When an abnormality occurs during the electric suction process, for example, the suction arm 22 cannot return to its position, such as the position shown in Figure 6, the mechanical cable 2 is pulled to make the locking arm 7 and the control arm 27 move clockwise together, driving the guide pin 29 to slide in the guide groove 33, thereby driving the emergency disengagement arm 28 to move clockwise. The emergency disengagement arm 28 moves clockwise so that the emergency disengagement arm disengagement structure 31 on the emergency disengagement arm 28 pushes the disengagement pin 21 to the right to move right, thereby causing the suction arm 22 to rotate clockwise. When it rotates to a certain angle, the suction arm suction structure 24 engages and separates with the lock tongue suction structure 23, thereby allowing the lock tongue 10 to move, that is, the suction arm 22 is disengaged, completing the emergency disengagement function of the electric suction.

[0078] The front hood lock 100 of the present application can realize emergency unlocking to deal with the situation where the front hood lock 100 cannot be unlocked due to a failure of the suction arm 22, thereby improving the reliability of the front hood lock 100. At the same time, the front hood lock 100 of the present application has a simple structure and is easy to manufacture and assemble.

[0079] A vehicle 200 according to another embodiment of the present application includes the hood lock 100 of the above embodiment.

[0080] According to the vehicle 200 of the embodiment of the present application, its hood lock 100 can lock the hood in the closed position, thereby preventing the hood of the vehicle 200 from lifting during driving, which is beneficial to improving the safety of the vehicle 200 during driving. In addition, the hood is locked in the closed position, which can also play an anti-theft role. The hood lock 100 can realize electric unlocking and electric unlocking of the hood. By realizing functions such as electric unlocking and electric suction, the functions integrated in the hood lock 100 are greatly improved, and the convenience is improved.
