Abstract

The application provides a left and right rudder integrated front hatch lock device, which comprises a bottom plate, a locking mechanism and an unlocking mechanism. The locking mechanism comprises a pawl and a ratchet wheel, and the pawl and the ratchet wheel have a fully open state, a half-lock state and a full-lock state. The unlocking mechanism comprises a release lever and a connecting rod. The rotating shaft of the release lever is arranged on the bottom plate. The two ends of the release lever are respectively provided with a first pulling part and a second pulling part. When the first pulling part and the second pulling part are pulled by external force to rotate the release lever in a first rotating direction, the pawl and the ratchet wheel are switched from the full-lock state to the half-lock state through the connecting rod, and then switched to the fully open state. The moving direction of the first pulling part is opposite to the moving direction of the second pulling part. The front hatch lock device can be applied to left-hand drive vehicles and right-hand drive vehicles at the same time, without the need for adjustment for left-hand drive vehicles and right-hand drive vehicles, thereby saving the material cost of preparing different front hatch lock devices for left-hand drive vehicles and right-hand drive vehicles.

Description

Technical Field

[0001] This invention relates to the field of automotive opening and closing components, specifically to a left and right rudder integrated hood locking device. Background Technology

[0002] Based on the position of the steering wheel on the vehicle, cars can be divided into left-hand drive cars and right-hand drive cars. Since traffic in China drives on the right, most cars on the Chinese market are left-hand drive.

[0003] However, with the development of China's automobile industry, more and more Chinese car brands have begun to go abroad and enter the world market. As a result, Chinese companies have also begun to produce right-hand drive cars in large quantities.

[0004] To facilitate unlocking the hood, the hood lock handle is usually located on the side closest to the driver's seat. To install the hood lock on a right-hand drive vehicle, the unlocking function is often achieved by mirroring the internal parts of the lock body, reversing the lock body, and adjusting the position of the unlocking cable. This not only results in high manufacturing costs but also poor compatibility with different vehicle models. Summary of the Invention

[0005] In view of this, the present invention aims to provide an integrated hood lock device for both left and right drive vehicles and an automobile, so as to solve the problems of high processing cost and poor adaptability to different vehicle models of the hood lock device on right-hand drive vehicles in the prior art.

[0006] This invention provides a left and right rudder integrated front hatch locking device, comprising:

[0007] Base plate;

[0008] A locking mechanism, comprising a pawl and a ratchet, wherein the pawl and the ratchet have a fully open state, a half-locked state, and a fully locked state;

[0009] The unlocking mechanism includes a release rod and a connecting rod. The rotation shaft of the release rod is disposed on the base plate. The two ends of the release rod are respectively provided with a first pulling part and a second pulling part. Both the first pulling part and the second pulling part are configured such that when the release rod is pulled by an external force to rotate in a first rotation direction, the pawl and the ratchet are switched from a fully locked state to a half-locked state, and then to a fully open state through the connecting rod. The direction of movement of the first pulling part controlled by the external force is opposite to the direction of movement of the second pulling part controlled by the external force.

[0010] In one embodiment of the present invention, the first pulling part and the second pulling part are configured to be in symmetrical positions relative to the rotation axis of the release rod.

[0011] In one embodiment of the present invention, the connecting rod is eccentrically disposed on one side of the release rod, and the first pulling part is disposed on the side of the release rod where the connecting rod is disposed, and the second pulling part is disposed on the side where the connecting rod is not disposed.

[0012] In one embodiment of the present invention, the connecting rod is provided with a first connecting rod mating part and a second connecting rod mating part; the pawl is provided with a pawl abutment part;

[0013] The release lever is configured such that when it is rotated from its initial position in a first rotation direction under the control of an external force, it drives the connecting rod to rotate from its initial position. In the fully locked state, the first mating part of the connecting rod abuts against the pawl abutting part, thereby pushing the pawl to a semi-locked state with the ratchet. In the semi-locked state, the second mating part of the connecting rod abuts against the pawl abutting part, thereby pushing the pawl to a fully open state with the ratchet.

[0014] In one embodiment of the present invention, the release lever is configured to be coaxial with the pawl and rotate freely relative to it;

[0015] The rotating shaft of the connecting rod is located on the release rod and can rotate freely. It is configured such that when the first mating part of the connecting rod abuts against the pawl abutting part, the relative angle between the connecting rod and the release rod is different from when the second mating part of the connecting rod abuts against the pawl abutting part.

[0016] In one embodiment of the present invention, in the fully locked state, as the release rod rotates from its initial position along the first rotation direction and drives the connecting rod to rotate together, the first mating part of the connecting rod and the pawl abutting part are opposite to each other in the first rotation direction, so that the first mating part of the connecting rod abuts against the pawl abutting part, pushing the pawl to be in a half-locked state with the ratchet.

[0017] In the semi-locked state, as the release lever rotates from its initial position along the first rotation direction and drives the connecting rod to rotate together, the second mating part of the connecting rod and the pawl abutting part are opposite to each other in the first rotation direction, so that the second mating part of the connecting rod abuts against the pawl abutting part, pushing the pawl to be in the fully open state with the ratchet.

[0018] In one embodiment of the invention, the second mating portion of the connecting rod is configured to protrude relative to the first mating portion of the connecting rod in a first rotational direction.

[0019] In one embodiment of the present invention, the unlocking mechanism further includes a connecting rod reset elastic element, which is configured to drive the connecting rod to rotate in a second rotation direction under its own elastic force, the second rotation direction being the opposite of the first rotation direction.

[0020] In one embodiment of the present invention, a first limiting part is provided on the base plate. The first limiting part is configured to limit the rotation angle of the connecting rod in the second rotation direction when the connecting rod is in the initial position, so as to ensure that in the fully locked state, during the process of the release rod rotating from the initial position along the first rotation direction and driving the connecting rod to rotate together, the first mating part of the connecting rod and the pawl abutting part are opposite to each other in the first rotation direction.

[0021] In one embodiment of the present invention, the connecting rod is provided with a connecting rod limiting part, which is configured to abut against the first limiting part when the connecting rod is in the initial position, so as to limit the rotation angle of the connecting rod in the second rotation direction.

[0022] In one embodiment of the present invention, the release rod is provided with a second limiting part, which is configured to limit the rotation angle of the connecting rod in the second rotation direction, so as to ensure that in the semi-locked state, when the release rod rotates from the initial position along the first rotation direction and drives the connecting rod to rotate together, the second mating part of the connecting rod and the pawl abutting part are opposite to each other in the first rotation direction.

[0023] In one embodiment of the present invention, the second limiting portion is configured to abut against the side of the first mating portion of the connecting rod to limit the rotation angle of the connecting rod in the second rotation direction.

[0024] In one embodiment of the present invention, the unlocking mechanism further includes a release rod reset elastic element, which is configured to drive the release rod to rotate in a second rotation direction under its own elastic force, the second rotation direction being the opposite direction to the first rotation direction.

[0025] In one embodiment of the present invention, a pop-up mechanism is further included, the pop-up mechanism including a pop-up rod and a pop-up elastic element, the pop-up rod being provided with a lifting part, the pop-up rod being configured to be controlled by the elastic force of the pop-up elastic element, and the lifting part being used to lift the lock.

[0026] The integrated left and right rudder front hatch locking device of the present invention is used in conjunction with a pull rope. The pull rope is fixed to one of the first pull part or the second pull part. When the pull rope is pulled, it can drive the release rod to rotate in the first rotation direction. When the release rod rotates in the first rotation direction, it can switch the pawl and ratchet from a fully locked state to a half-locked state through the connecting rod, and then switch to a fully open state, thereby unlocking the integrated left and right rudder front hatch locking device of the present invention.

[0027] Whether the pull rope is fixed to the first pull part or the pull rope is fixed to the second pull part, it can be controlled by external force to drive the release rod to rotate in the first rotation direction, thereby unlocking the left and right rudder integrated front hatch lock device of the present invention. This makes it easier to flexibly set the extension direction of the pull rope and better meet the installation requirements.

[0028] When the integrated left and right hood locking device of the present invention is applied to a car to lock the latch on the hood, since cars are divided into left-hand drive and right-hand drive, that is, the driver's seat is located on the left side of the car body and the right side of the car body, and in order to facilitate the driver to unlock the hood, the hood handle is usually located near the outside of the driver.

[0029] Thus, when the handle is located on the right side of the diagram, the pull rope can be fixed to the first pull part. When the user pulls the handle, thereby pulling the pull rope to the right, the release lever will rotate in the first rotation direction, unlocking the integrated left and right rudder canopy lock device of this invention. When the handle is located on the left side of the diagram, the pull rope can be fixed to the second pull part. When the user pulls the handle, thereby pulling the pull rope to the left, the release lever will also rotate in the first rotation direction, unlocking the integrated left and right rudder canopy lock device of this invention.

[0030] As can be seen, when the integrated left-hand drive hood lock device of the present invention is applied to automobiles, regardless of whether the automobile is left-hand drive or right-hand drive, there is no need to adjust the setting direction of the integrated left-hand drive hood lock device of the present invention, nor is it necessary to prepare two sets of mirror images of each other for left-hand drive and right-hand drive automobiles. Furthermore, when the integrated left-hand drive hood lock device of the present invention is applied to left-hand drive and right-hand drive automobiles, it can maintain the same arrangement position and direction. Designers only need to adjust the fixing position of the pull rope on the release lever according to the setting position of the handle. This allows for the simultaneous unlocking function of both left-hand drive and right-hand drive automobiles using a single release lever, without requiring technicians to make other adjustments to the integrated left-hand drive hood lock device for left-hand drive and right-hand drive automobiles. This significantly reduces the development cost of changing a left-hand drive automobile to a right-hand drive version or a right-hand drive automobile to a left-hand drive version, and also saves the material cost of preparing different integrated left-hand drive hood lock devices for left-hand drive and right-hand drive automobiles respectively.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] This invention provides an integrated left- and right-hand drive hood lock device, including a base plate, a locking mechanism, and an unlocking mechanism. The base plate is used to install various components within the integrated left- and right-hand drive hood lock device and to fix the integrated left- and right-hand drive hood lock device of this invention in a location such as the front engine compartment of a vehicle.

[0044] The locking mechanism includes a pawl and a ratchet, which can be in a fully open, half-locked, and fully locked state. The unlocking mechanism includes a release rod and a connecting rod. The rotation shaft of the release rod is set on the base plate. The two ends of the release rod are respectively provided with a first pulling part and a second pulling part. Both the first pulling part and the second pulling part are configured such that when the release rod is pulled by an external force to rotate in a first rotation direction, the connecting rod switches the pawl and ratchet from a fully locked state to a half-locked state, and then to a fully open state. The direction of movement of the first pulling part controlled by the external force is opposite to the direction of movement of the second pulling part controlled by the external force.

[0045] The integrated left and right rudder front hatch locking device of the present invention is used in conjunction with a pull rope. The pull rope is fixed to one of the first pull part or the second pull part. When the pull rope is pulled, it can drive the release rod to rotate in the first rotation direction. When the release rod rotates in the first rotation direction, it can switch the pawl and ratchet from a fully locked state to a half-locked state through the connecting rod, and then switch to a fully open state, thereby unlocking the integrated left and right rudder front hatch locking device of the present invention.

[0046] Whether the pull rope is fixed to the first pull part or the pull rope is fixed to the second pull part, it can be controlled by external force to drive the release rod to rotate in the first rotation direction, thereby unlocking the left and right rudder integrated front hatch lock device of the present invention. This makes it easier to flexibly set the extension direction of the pull rope and better meet the installation requirements.

[0047] When the integrated left and right hood locking device of the present invention is applied to a car to lock the latch on the hood, since cars are divided into left-hand drive and right-hand drive, that is, the driver's seat is located on the left side of the car body and the right side of the car body, and in order to facilitate the driver to unlock the hood, the hood handle is usually located near the outside of the driver.

[0048] Thus, when the handle is located on the right side of the diagram, the pull rope can be fixed to the first pull part. When the user pulls the handle, thereby pulling the pull rope to the right, the release lever will rotate in the first rotation direction, unlocking the integrated left and right rudder canopy lock device of this invention. When the handle is located on the left side of the diagram, the pull rope can be fixed to the second pull part. When the user pulls the handle, thereby pulling the pull rope to the left, the release lever will also rotate in the first rotation direction, unlocking the integrated left and right rudder canopy lock device of this invention.

[0049] As can be seen, when the integrated left-hand drive hood lock device of the present invention is applied to automobiles, regardless of whether the automobile is left-hand drive or right-hand drive, there is no need to adjust the setting direction of the integrated left-hand drive hood lock device of the present invention, nor is it necessary to prepare two sets of mirror images of each other for left-hand drive and right-hand drive automobiles. Furthermore, when the integrated left-hand drive hood lock device of the present invention is applied to left-hand drive and right-hand drive automobiles, it can maintain the same arrangement position and direction. Designers only need to adjust the fixing position of the pull rope on the release lever according to the setting position of the handle. This allows for the simultaneous unlocking function of both left-hand drive and right-hand drive automobiles using a single release lever, without requiring technicians to make other adjustments to the integrated left-hand drive hood lock device for left-hand drive and right-hand drive automobiles. This significantly reduces the development cost of changing a left-hand drive automobile to a right-hand drive version or a right-hand drive automobile to a left-hand drive version, and also saves the material cost of preparing different integrated left-hand drive hood lock devices for left-hand drive and right-hand drive automobiles respectively.

[0050] For ease of understanding, please refer to the following: Figures 1 to 9 The present invention will be described in detail with reference to the embodiments of the integrated left and right rudder hood locking device and automobile of the present invention.

[0051] like Figures 1 to 3 As shown, the present invention provides a left-right rudder integrated hood locking device 100, including a base plate 30, a locking mechanism 10, and an unlocking mechanism 20. The base plate 30 is used to install various components inside the left-right rudder integrated hood locking device 100, and to fix the left-right rudder integrated hood locking device 100 of the present invention in a position such as the front engine compartment of an automobile.

[0052] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the locking mechanism 10 includes a pawl 11 and a ratchet 13. The pawl 11 and the ratchet 13 have a fully open state, a half-locked state, and a fully locked state. When the pawl 11 and the ratchet 13 are in the half-locked state or the fully locked state, the latch 200 can be locked onto the left and right rudder integrated front hatch locking device 100 to achieve the locking purpose. When the pawl 11 and the ratchet 13 are in the fully open state, the latch 200 can be released to achieve the unlocking purpose.

[0053] Specifically, such as Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the rotation shaft of the pawl 11 is disposed on the base plate 30 and includes a pawl engagement portion 112; the rotation shaft of the ratchet 13 is disposed on the base plate 30, including a ratchet first engagement portion 131 and a ratchet second engagement portion 132, and is configured such that when the ratchet 13 is in the fully open state, as it rotates along the second rotation direction N under external force, the pawl engagement portion 112 moves to abut against the ratchet first engagement portion 131 to enter a half-locked state; when the ratchet 13 is in the half-locked state, as it rotates along the second rotation direction N under external force, the pawl engagement portion 112 moves to abut against the ratchet second engagement portion 132 to enter a fully locked state.

[0054] That is, Figures 8A to 8C As shown, before the integrated left and right rudder front canopy locking device 100 of the present invention is locked, the pawl 11 and the ratchet 13 are in a fully open state. During the locking process of the integrated left and right rudder front canopy locking device 100 of the present invention, the latch 200 can push the ratchet 13 to rotate in the second rotation direction N, thereby driving the pawl engagement portion 112 to move to abut against the first engagement portion 131 of the ratchet, so as to enter a half-lock state; then, the latch 200 can continue to push the ratchet 13 to rotate in the second rotation direction N, driving the pawl engagement portion 112 to move to abut against the second engagement portion 132 of the ratchet, so as to enter a fully locked state, thereby realizing the locking of the latch 200.

[0055] As can be seen, during the locking process of the integrated left and right rudder front hatch locking device 100 of the present invention, the user can press the latch 200 continuously once to realize the transformation of the integrated left and right rudder front hatch locking device 100 from the fully open state to the half-locked state and then to the fully locked state, without the user having to press the latch 200 twice, which effectively simplifies the locking process and improves the user experience.

[0056] like Figure 3 and Figure 6 As shown, the rotation shaft of the release rod 21 is set on the base plate 30. The two ends of the release rod 21 are respectively provided with a first pulling part 211 and a second pulling part 212. The first pulling part 211 and the second pulling part 212 are both configured so that when the release rod 21 is pulled by an external force to rotate in the first rotation direction M, the pawl 11 and the ratchet 13 are switched from a fully locked state to a half-locked state through the connecting rod 23, and then switched to a fully open state. The direction of movement of the first pulling part 211 under the control of the external force is opposite to the direction of movement of the second pulling part 212 under the control of the external force.

[0057] The left and right rudder integrated front hatch locking device 100 of the present invention is used in conjunction with a pull rope. The pull rope is fixed to one of the first pull part 211 or the second pull part 212. When the pull rope is pulled, it can drive the release rod 21 to rotate in the first rotation direction M. When the release rod 21 rotates in the first rotation direction M, it can switch the pawl 11 and the ratchet 13 from a fully locked state to a half-locked state through the connecting rod 23, and then switch to a fully open state, thereby unlocking the left and right rudder integrated front hatch locking device 100 of the present invention.

[0058] Whether the tow rope is fixed to the first tow section 211 or the tow rope is fixed to the second tow section 212, it can be controlled by external force to drive the release rod 21 to rotate in the first rotation direction M, thereby unlocking the left and right rudder integrated front hatch locking device 100 of the present invention, which makes it easier to flexibly set the extension direction of the tow rope and better meet the installation requirements.

[0059] Specifically, such as Figure 6 As shown, the direction of movement Q of the pull rope under the control of external force when it is fixed to the first pull part 211 is opposite to the direction of movement R of the pull rope under the control of external force when it is fixed to the second pull part 212. Figure 6 Taking the direction in the middle as a reference, when the pulling rope is fixed to the first pulling part 211, when it is controlled by an external force to move to the right, it can drive the release rod 21 to rotate along the first rotation direction M; when the pulling rope is fixed to the second pulling part 212, when it is controlled by an external force to move to the left, it can also drive the release rod 21 to rotate along the first rotation direction M.

[0060] When the left and right hood integrated locking device 100 of the present invention is applied to a car to lock the latch 200 on the hood, since cars are divided into left-hand drive and right-hand drive, that is, the driver's seat is located on the left side of the car body and the right side of the car body, and in order to facilitate the driver to unlock the hood, the hood handle is usually located on the outside of the driver.

[0061] Thus, when the handle is in Figure 1 When the handle is on the right side, the pull rope can be fixed to the first pull part 211. Thus, when the user pulls the handle, thereby pulling the pull rope to the right, the release lever 21 will rotate along the first rotation direction M, unlocking the left and right rudder integrated front hatch locking device 100 of this invention. When the handle is in the right position... Figure 1 When the handle is on the left side, the pull rope can be fixed to the second pull part 212. In this way, when the user pulls the handle and pulls the pull rope to move to the left, the release lever 21 can also be rotated along the first rotation direction M, thereby unlocking the left and right rudder integrated front hatch locking device 100 of the present invention.

[0062] As can be seen, when the integrated left and right hood locking device 100 of the present invention is applied to a car, regardless of whether the car is left-hand drive or right-hand drive, there is no need to adjust the setting direction of the integrated left and right hood locking device 100 of the present invention, nor is it necessary to prepare two sets of mirror images of the integrated left and right hood locking devices 100 for left-hand drive and right-hand drive cars. Furthermore, when the integrated left and right hood locking device 100 of the present invention is applied to left-hand drive and right-hand drive cars, it can maintain the same arrangement position and direction. Designers only need to adjust the fixed position of the pull rope on the release lever 21 according to the setting position of the handle. This allows for the simultaneous unlocking function of both left-hand drive and right-hand drive cars using a single release lever 21, without requiring technicians to make other adjustments to the integrated left and right hood locking device 100 for left-hand drive and right-hand drive cars. This significantly reduces the development cost of changing a left-hand drive car to a right-hand drive version or a right-hand drive car to a left-hand drive version, and also saves material costs associated with preparing different integrated left and right hood locking devices 100 for left-hand drive and right-hand drive cars respectively.

[0063] It is understood that, in one embodiment of the present invention, the first pulling part 211 and the second pulling part 212 are configured to be in symmetrical positions relative to the rotation axis O of the release lever 21. When the first pulling part 211 and the second pulling part 212 are in symmetrical positions relative to the rotation axis O of the release lever 21, it can be ensured that the operating stroke of the left and right hood locking device 100 of the present invention is the same in both left-hand drive and right-hand drive vehicles, thereby improving the user experience.

[0064] like Figure 6 As shown, in one embodiment of the present invention, the connecting rod 23 is eccentrically disposed on one side of the release rod 21, and a first pulling part 211 is provided on the side of the release rod 21 where the connecting rod 23 is disposed, and a second pulling part 212 is provided on the side where the connecting rod 23 is not disposed.

[0065] Whether the tow rope is fixed to the first tow section 211 or the tow rope is fixed to the second tow section 212, it can be controlled by external force to drive the release rod 21 to rotate in the first rotation direction M, thereby unlocking the left and right rudder integrated front hatch locking device 100 of the present invention, which makes it easier to flexibly set the extension direction of the tow rope and better meet the installation requirements.

[0066] It is understandable that, such as Figure 5As shown, to ensure that the pawl engagement portion 112 can sequentially abut against the first engagement portion 131 and the second engagement portion 132 of the ratchet during the rotation of the ratchet 13, and to maintain both a fully locked and a partially locked state, the first engagement portion 131 and the second engagement portion 132 of the ratchet can be stepped as a whole to ensure that the pawl engagement portion 112 can maintain a stable engagement with the first engagement portion 131 and the second engagement portion 132 of the ratchet. Furthermore, an arc-shaped or straight guide surface is provided between the first engagement portion 131 and the second engagement portion 132 of the ratchet to ensure that the pawl engagement portion 112 can switch from abutting against the first engagement portion 131 to abutting against the second engagement portion 132 of the ratchet. The specific shapes of the first engagement portion 131 and the second engagement portion 132 of the ratchet, and the shape of the guide surface, can be practically set and are not limited here.

[0067] Furthermore, such as Figure 1 As shown, in one embodiment of the present invention, the locking mechanism 10 further includes a pawl reset elastic member 12 and a ratchet reset elastic member 14; the pawl reset elastic member 12 is configured to drive the pawl 11 to rotate along the second rotation direction N under its own elastic force; the ratchet reset elastic member 14 is configured to drive the ratchet 13 to rotate along the first rotation direction M under its own elastic force.

[0068] It can be seen that by setting the pawl reset elastic element 12 and the ratchet reset elastic element 14, and making the rotation direction of the pawl 11 driven by the pawl reset elastic element 12 opposite to the rotation direction of the ratchet 13 driven by the ratchet reset elastic element 14, it is convenient for the pawl 11 and the ratchet 13 to abut and engage with each other using the pawl engaging part 112 and the first engaging part 131 or the second engaging part 132 of the ratchet. This allows the left and right rudder integrated front hatch locking device 100 of the present invention to be maintained in a half-locked or fully locked state, avoiding dangerous situations such as unlocking.

[0069] like Figures 1 to 3 , Figure 6 and Figure 7 As shown, the unlocking mechanism 20 includes a release rod 21 and a connecting rod 23. The rotation shaft of the release rod 21 is set on the base plate 30, and the connecting rod 23 is set on the release rod 21. It is provided with a first connecting rod mating part 231 and a second connecting rod mating part 232. The pawl 11 is provided with a pawl abutment part 111.

[0070] Specifically, the release lever 21 is configured such that when it is rotated from its initial position along the first rotation direction M under the control of an external force, it drives the connecting lever 23 to rotate from its initial position. In the fully locked state, the first mating part 231 of the connecting lever abuts against the pawl abutting part 111, thereby pushing the pawl 11 to a semi-locked state with the ratchet 13. In the semi-locked state, the second mating part 232 of the connecting lever abuts against the pawl abutting part 111, thereby pushing the pawl 11 to a fully open state with the ratchet 13.

[0071] That is, Figure 9A As shown, during the use of the integrated left and right rudder front hatch locking device 100 of the present invention, the pawl 11 and the ratchet 13 are usually in a fully locked state, thereby locking the latch 200 onto the integrated left and right rudder front hatch locking device 100. Figures 9B to 9E As shown, when a user needs to unlock the integrated left and right rudder front hatch locking device 100 of the present invention, by directly or indirectly pulling the release lever 21, the release lever 21 can rotate from its initial position along the first rotation direction M, thereby driving the connecting rod 23 to rotate from its initial position. The first mating part 231 of the connecting rod 23 can then abut against the pawl abutment part 111, pushing the pawl 11 to a semi-locked state with the ratchet 13. Figure 9F As shown, after switching to the half-lock state, the user releases the release lever 21, and both the release lever 21 and the connecting lever 23 return to their initial positions.

[0072] Then, as Figure 9G , Figure 9H and Figure 9I As shown, in the half-locked state, when the user pulls the release lever 21 again, causing it to rotate again from its initial position along the first rotation direction M, the connecting lever 23 rotates from its initial position again. At this time, the second mating part 232 of the connecting lever 23 abuts against the pawl abutting part 111, pushing the pawl 11 to be fully open with the ratchet 13, thereby releasing the lock 200. Figure 9J As shown, when the device is in the fully open state, if the user releases the release lever 21 again, both the release lever 21 and the connecting lever 23 will return to their initial positions in preparation for the next unlocking.

[0073] As can be seen, during the unlocking process of the integrated left and right hood lock device 100 of the present invention, the user can achieve the unlocking purpose by pulling the release lever 21 twice in succession. When the integrated left and right hood lock device 100 of the present invention is installed on the hood of a car, the user only needs to pull the handle corresponding to the integrated left and right hood lock device 100 of the present invention twice to unlock the hood of the car; there is no need for the user to unlock the integrated left and right hood lock device 100 inside the car and then go outside the car to unlock the safety hook to open the hood, providing the user with a convenient and quick operating experience.

[0074] Furthermore, compared to the existing left and right rudder integrated front hatch locking device 100, the left and right rudder integrated front hatch locking device 100 of the present invention utilizes two different mating parts of a single connecting rod 23 to abut against the pawl abutment part 111 respectively during the two-stage unlocking process, which effectively simplifies the corresponding unlocking mechanism 20, not only making assembly simple, but also reducing the parts cost of the left and right rudder integrated front hatch locking device 100 of the present invention.

[0075] Specifically, such as Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the base plate 30 is provided with a locking port 311 that opens to the outside of the integrated left and right rudder front hatch locking device 100 along the third direction P. The ratchet 13 includes a ratchet locking part and is configured such that when it is in a fully locked state and a half locked state, the ratchet locking part closes the locking port 311 so that the latch 200 is locked in the locking port 311, and when it is in a fully open state, the locking port 311 is opened so that the latch 200 can be moved out of the locking port 311.

[0076] When the ratchet 13 is in the fully locked or partially locked state, the ratchet locking part can close the locking port 311, so that the latch 200 is locked inside the locking port 311, preventing the latch 200 from coming out of the locking port 311 and ensuring effective locking. When the ratchet 13 is in the fully open state, the locking port 311 is opened, so that the latch 200 can be moved out of the locking port 311, realizing the unlocking function.

[0077] like Figure 2 As shown, in one embodiment of the present invention, the pawl 11 is configured to be coaxial with the release rod 21 and rotate freely relative to it; the rotation axis of the connecting rod 23 is provided on the release rod 21, and is configured such that when the first mating part 231 of the connecting rod abuts against the pawl abutting part 111, the relative angle between the connecting rod and the release rod 21 is different from when the second mating part 232 of the connecting rod abuts against the pawl abutting part 111.

[0078] It is understandable that, since the pawl 11 and the release lever 21 share the same rotation axis O, when the connecting rod 23 is fixed to the release lever 21, it can only abut against the pawl abutment part 111 at the same position.

[0079] Therefore, in the left and right rudder integrated front hatch locking device 100 of the present invention, the rotation axis of the connecting rod 23 is provided on the release rod 21, and is configured such that when the first mating part 231 of the connecting rod abuts against the pawl abutting part 111, the relative angle between the connecting rod and the release rod 21 is different from that when the second mating part 232 of the connecting rod abuts against the pawl abutting part 111. This ensures that the connecting rod 23 can rotate relative to the release rod 21, so that in the fully locked state or the half-locked state, the first mating part 231 or the second mating part 232 of the connecting rod abuts against the pawl abutting part 111, respectively, to push the pawl 11 to rotate.

[0080] Specifically, such as Figures 9A to 9J As shown, in one embodiment of the present invention, in the fully locked state, as the release lever 21 rotates from its initial position along the first rotation direction M and drives the connecting lever 23 to rotate together, the first mating part 231 of the connecting lever and the pawl abutting part 111 are opposite each other in the first rotation direction M, so that the first mating part 231 of the connecting lever and the pawl abutting part 111 abut against each other, pushing the pawl 11 to be in a half-locked state with the ratchet 13;

[0081] In the semi-locked state, as the release lever 21 rotates from its initial position along the first rotation direction M and drives the connecting lever 23 to rotate together, the second mating part 232 of the connecting lever and the pawl abutting part 111 are opposite each other in the first rotation direction M, so that the second mating part 232 of the connecting lever and the pawl abutting part 111 abut against each other, pushing the pawl 11 to be in the fully open state with the ratchet 13.

[0082] In the fully locked state, as the release lever 21 drives the connecting lever 23 to rotate, the first mating part 231 of the connecting lever and the pawl abutment part 111 are aligned in the first rotation direction M. This allows the first mating part 231 of the connecting lever to move under the influence of the release lever 21 until it abuts against the pawl abutment part 111, thereby pushing the pawl 11 to a semi-locked state with the ratchet 13. After pushing the pawl 11 to a semi-locked state with the ratchet 13, both the release lever 21 and the connecting lever 23 return to their initial positions.

[0083] In the semi-locked state, as the release lever 21 drives the connecting rod 23 to rotate, the second mating part 232 of the connecting rod and the pawl abutment part 111 are opposite each other in the first rotation direction M, so that the second mating part 232 of the connecting rod can move under the drive of the release lever 21 to abut against the pawl abutment part 111, thereby pushing the pawl 11 to be in the fully open state with the ratchet 13.

[0084] It is understandable that, such as Figure 9D and Figure 9HAs shown, in the fully locked state, the release lever 21 rotates from its initial position along the first rotation direction M, causing the connecting lever 23 to rotate together. In the half-locked state, the release lever 21 rotates from its initial position along the first rotation direction M, causing the connecting lever 23 to rotate together. In at least one of these two processes, the connecting lever 23 rotates relative to the release lever 21. This allows the relative angle between the connecting lever 23 and the release lever 21 to differ when the first mating part 231 of the connecting lever abuts against the pawl abutting part 111, and when the second mating part 232 of the connecting lever abuts against the pawl abutting part 111. Therefore, in both unlocking processes, the first mating part 231 or the second mating part 232 of the connecting lever is positioned opposite the pawl abutting part 111, thereby utilizing the contact between the first mating part 231 or the second mating part 232 of the connecting lever and the pawl abutting part 111 to push the pawl 11 to rotate.

[0085] Of course, such as Figure 9A , Figure 9D and Figure 9H As shown in this embodiment, in the fully locked state, the process of the release rod 21 rotating from its initial position along the first rotation direction M and causing the connecting rod 23 to rotate together, and in the half-locked state, the process of the release rod 21 rotating from its initial position along the first rotation direction M and causing the connecting rod 23 to rotate together, both involve the connecting rod 23 rotating relative to the release rod 21, but the rotation angles are different.

[0086] Furthermore, such as Figure 3 As shown, in one embodiment of the present invention, the second mating portion 232 of the connecting rod is configured to protrude relative to the first mating portion 231 of the connecting rod in a first rotational direction M;

[0087] The pawl abutment portion 111 is configured to abut against the first mating portion 231 of the connecting rod and, during the rotation controlled by the first mating portion 231 of the connecting rod, to fit against the side of the second mating portion 232 of the connecting rod, thereby restricting the rotation of the connecting rod 23 and maintaining abutment against the first mating portion 231 of the connecting rod.

[0088] Since the second mating part 232 of the connecting rod protrudes relative to the first mating part 231 of the connecting rod in the first rotation direction M, in the fully locked state, during the process of the release rod 21 driving the connecting rod 23 to rotate, the pawl abutting part 111 not only abuts against the first mating part 231 of the connecting rod and is controlled by the rotation of the first mating part 231 of the connecting rod, but also fits against the side of the second mating part 232 of the connecting rod. In this way, the side of the second mating part 232 of the connecting rod can restrict the rotation of the connecting rod 23, so that the pawl abutting part 111 remains in the abutting state with the first mating part 231 of the connecting rod until the pawl 11 moves to the half-locked state.

[0089] It is understandable that, such as Figure 3As shown, the first mating part 231 and the second mating part 232 of the connecting rod can be Figure 3 The stepped shape can also be other shapes, as long as the above requirements are met.

[0090] like Figure 9A , Figure 9E and Figure 9I As shown, in one embodiment of the present invention, the rotation axis of the pawl 11 is disposed on the base plate 30 and is configured to rotate and switch between the fully locked pawl position in the fully locked state, the half-locked pawl position in the half-locked state, and the fully open pawl position in the fully open state under the control of external force. The fully locked pawl position, the half-locked pawl position, and the fully open pawl position are successively moved away from the initial position of the connecting rod 23 in the first rotation direction M.

[0091] In the fully locked state, when the release lever rotates from its initial position along the first rotation direction M, it drives the connecting rod 23 to rotate from its initial position. The first mating part 231 of the connecting rod 23 then abuts against the pawl abutment part 111, pushing the pawl 11 from the fully locked pawl position to the half-locked pawl position, thus switching the pawl 11 and ratchet 13 to the half-locked state. After switching to the half-locked state, both the release lever 21 and the connecting rod 23 return to their initial positions.

[0092] Then, in the half-locked state, when the release lever rotates again from its initial position along the first rotation direction M, it drives the connecting rod 23 to rotate from its initial position again. At this time, the second mating part 232 of the connecting rod 23 abuts against the pawl abutting part 111, pushing the pawl 11 from the half-locked pawl position to the fully open pawl position, thereby switching the pawl 11 and the ratchet 13 to the fully open state. That is, in the above two unlocking processes, the connecting rod always pushes the pawl 11 to rotate in the same direction, namely the first rotation direction M, but the part of the connecting rod that pushes the pawl abutting part 111 is different in the two unlocking processes.

[0093] Because the fully locked, half-locked, and fully open pawl positions are successively moved away from the initial position of the connecting rod 23 in the first rotation direction M, and the second mating part 232 of the connecting rod protrudes relative to the first mating part 231 of the connecting rod in the first rotation direction M, it can be ensured that during the first unlocking process, when the release rod 21 is pulled to rotate a preset angle, the first mating part 231 of the connecting rod can only push the pawl 11 from the fully locked pawl position to the half-locked pawl position, and cannot continue to push it to the fully open pawl position, thus avoiding the situation where the first unlocking process directly switches to the fully open state. When the integrated left and right rudder hood lock device 100 of the present invention is applied to the front hood of a car, the user cannot unlock the hood directly by pulling the handle once, thus ensuring safety. During the second unlocking process, when the release lever 21 is pulled again to rotate the preset angle, since the second mating part 232 of the connecting rod is more prominent than the first mating part 231 of the connecting rod in the first rotation direction M, the second mating part 232 of the connecting rod can push the pawl 11 from the half-locked pawl position to the fully open pawl position, so as to unlock the integrated left and right rudder hood lock device 100.

[0094] It is understandable that the protruding length of the second mating part 232 of the connecting rod relative to the first mating part 231 of the connecting rod can be set according to the corresponding rotational stroke of the fully locked pawl position, the half-locked pawl position, and the fully open pawl position to meet the above requirements.

[0095] like Figure 3 As shown, in one embodiment of the present invention, the second mating part 232 of the connecting rod is configured such that, when in the initial position, the front end protrudes along the first rotation direction M relative to the abutment surface of the pawl abutment part 111 when in the fully locked pawl position.

[0096] That is, Figure 9A As shown, since the front end of the second mating part 232 of the connecting rod protrudes along the first rotation direction M relative to the abutment surface of the pawl abutment part 111 when it is in the fully locked pawl position when it is in the initial position, it can be ensured that in the fully locked state, when the release rod 21 drives the connecting rod 23 to move, the front end of the second mating part 232 of the connecting rod is located in front of the abutment surface of the pawl abutment part 111 in the first rotation direction M. Only the first mating part 231 of the connecting rod and the abutment surface of the pawl abutment part 111 can be opposite each other. The front end of the second mating part 232 of the connecting rod cannot be opposite to the abutment surface of the pawl abutment part 111. This ensures that during the first unlocking process, the first mating part 231 of the connecting rod abuts against the pawl abutment part 111 and pushes the pawl 11 to rotate, avoiding the situation where the front end of the second mating part 232 of the connecting rod abuts against the pawl abutment part 111, and preventing the situation where the first unlocking process directly switches to the fully open state.

[0097] It is understandable that whether the second mating part 232 of the connecting rod needs to be located on the side of the first mating part 231 of the connecting rod adjacent to the rotation axis O of the release rod 21, or on the side of the first mating part 231 of the connecting rod away from the rotation axis O of the release rod 21, depends on the position of the pawl abutment part 111 in the fully locked pawl position and the pawl abutment part 111 in the half-locked pawl position.

[0098] like Figure 3 As shown, in one embodiment of the present invention, the second mating part 232 of the connecting rod is disposed on the side of the first mating part 231 of the connecting rod adjacent to the rotation axis O of the release rod 21; while in another embodiment of the present invention, the second mating part 232 of the connecting rod may also be disposed on the side of the first mating part 231 of the connecting rod away from the rotation axis O of the release rod 21.

[0099] It is understandable that, such as Figure 1 As shown, in one embodiment of the present invention, when the second mating part 232 of the connecting rod is disposed on the side of the first mating part 231 of the connecting rod adjacent to the rotation axis O of the release rod 21, the unlocking mechanism 20 further includes a connecting rod reset elastic member 24. The connecting rod reset elastic member 24 is configured to drive the connecting rod 23 to rotate along the second rotation direction N under its own elastic force. The second rotation direction N is the opposite direction to the first rotation direction M.

[0100] By setting the connecting rod reset elastic element 24, in the fully locked state, when the release rod 21 drives the connecting rod 23 to rotate together, the connecting rod 23 is rotated by the connecting rod reset elastic element 24 in the second rotation direction N by a first angle r1, so that the first mating part 231 of the connecting rod and the pawl abutting part 111 are opposite each other in the first rotation direction M. The first mating part 231 of the connecting rod and the pawl abutting part 111 abut against each other and push the pawl 11 to rotate. In the half-locked state, when the release rod 21 drives the connecting rod 23 to rotate together, the connecting rod 23 is rotated by the connecting rod reset elastic element 24 in the second rotation direction N by a second angle r2, so that the second mating part 232 of the connecting rod and the pawl abutting part 111 are opposite each other in the first rotation direction M. The second mating part 232 of the connecting rod and the pawl abutting part 111 abut against each other and push the pawl 11 to rotate. It can also be realized that after the connecting rod 23 and the pawl 11 are separated, it can return to the initial position.

[0101] It is understandable that, as mentioned above, during the first unlocking process, the side of the second mating part 232 of the connecting rod can restrict the rotation of the connecting rod 23, so that the pawl abutment part 111 remains in contact with the first mating part 231 of the connecting rod. Therefore, during the first unlocking process, the connecting rod 23 is rotated by the connecting rod reset elastic member 24 in the second rotation direction N by a first angle r1, which is related to the side setting position of the second mating part 232 of the connecting rod.

[0102] Furthermore, such as Figure 9A As shown, in one embodiment of the present invention, a first limiting part 32 is provided on the base plate 30. The first limiting part 32 is configured to limit the rotation angle of the connecting rod 23 in the second rotation direction N when the connecting rod is in the initial position, so as to ensure that in the fully locked state, when the release rod 21 rotates from the initial position along the first rotation direction M and drives the connecting rod 23 to rotate together, the first mating part 231 of the connecting rod and the pawl abutment part 111 are opposite to each other in the first rotation direction M.

[0103] By setting a first limiting part 32 at a specific position on the base plate 30, the first limiting part 32 can limit the rotation angle of the connecting rod 23 in the second rotation direction N when the connecting rod is in the initial position, ensuring that the first mating part 231 of the connecting rod and the pawl abutment part 111 are opposite to each other in the first rotation direction M, and avoiding the situation where the connecting rod 23 is rotated too much in the second rotation direction N by the connecting rod reset elastic member 24, resulting in the first mating part 231 of the connecting rod and the pawl abutment part 111 being unable to be opposite to each other in the first rotation direction M.

[0104] Furthermore, such as Figure 9A As shown, a connecting rod limiting part 233 is provided on the connecting rod 23. The connecting rod limiting part 233 is configured to abut against the first limiting part 32 when the connecting rod is in the initial position, thereby limiting the rotation angle of the connecting rod 23 in the second rotation direction N. By providing the connecting rod limiting part 233 on the connecting rod 23, the connecting rod limiting part 233 can abut against the first limiting part 32 when the connecting rod is in the initial position, thereby limiting the rotation angle of the connecting rod 23 in the second rotation direction N, ensuring that the first mating part 231 of the connecting rod and the pawl abutting part 111 are opposite each other in the first rotation direction M.

[0105] Understandably, in order to... Figure 9A The first limiting part 32 on the base plate 30 abuts against the connecting rod, and the connecting rod limiting part 233 is disposed on the side of the connecting rod 23 away from the first mating part 231 and the second mating part 232 of the connecting rod; in another embodiment of the present invention, the connecting rod limiting part 233 can be determined according to the specific setting position and angle restriction requirements of the first limiting part 32, and is not limited here.

[0106] like Figure 9G As shown, in one embodiment of the present invention, a second limiting part 213 is provided on the release rod 21. The second limiting part 213 is configured to limit the rotation angle of the connecting rod 23 in the second rotation direction N, so as to ensure that in the half-locked state, when the release rod 21 rotates from the initial position along the first rotation direction M and drives the connecting rod 23 to rotate together, the second mating part 232 of the connecting rod and the pawl abutment part 111 are opposite to each other in the first rotation direction M.

[0107] By setting a second limiting part 213 at a specific position of the release rod 21, the second limiting part 213 can limit the rotation angle of the connecting rod 23 in the second rotation direction N, so as to ensure that in the semi-locked state, the second mating part 232 of the connecting rod and the pawl abutment part 111 are opposite to each other in the first rotation direction M, and avoid the connecting rod 23 being rotated too much in the second rotation direction N by the connecting rod reset elastic member 24, which would cause the second mating part 232 of the connecting rod and the pawl abutment part 111 to be unable to be opposite to each other in the first rotation direction M.

[0108] like Figure 9G As shown, in one embodiment of the present invention, the second limiting part 213 is configured to abut against the side of the first engaging part 231 of the connecting rod to limit the rotation angle of the connecting rod 23 in the second rotation direction N. Since the second limiting part 213 abuts against the side of the first engaging part 231 of the connecting rod, it can not only limit the rotation angle of the connecting rod 23 in the second rotation direction N, but also not limit the connecting rod 23 from rotating with the release rod 21 as a whole in the first rotation direction M, ensuring that the second engaging part 232 of the connecting rod can push the pawl 11 from the half-locked pawl position to the fully open pawl position, so as to unlock the left and right rudder integrated front hatch locking device 100.

[0109] It is understandable that, since the rotation axis of the connecting rod 23 is set on the release rod 21, such as Figure 1 As shown, in one embodiment of the present invention, one end of the connecting rod reset elastic member 24 is engaged with the connecting rod 23, and the other end is engaged with the release rod 21. This enables the connecting rod reset elastic member 24 to drive the connecting rod 23 to rotate along the second rotation direction N under its own elastic force.

[0110] like Figure 1 As shown, in one embodiment of the present invention, the unlocking mechanism 20 further includes a release rod reset elastic element 22. The release rod reset elastic element 22 is configured to drive the release rod 21 to rotate along a second rotation direction N under its own elastic force. The second rotation direction N is the opposite direction to the first rotation direction M. By providing the release rod reset elastic element 22, it can be ensured that after the tension of the traction rope is removed, the release rod reset elastic element 22 can drive the release rod 21 to rotate along the second rotation direction N under its own elastic force, thereby restoring the release rod 21 to its initial position.

[0111] It is understandable that, since the rotation axis of the release rod 21 is set on the base plate 30, one end of the release rod reset elastic member 22 is engaged with the release rod 21 and the other end is engaged with the base plate 30, so as to ensure that the release rod reset elastic member 22 can drive the release rod 21 to rotate along the second rotation direction N under its own elastic force, thereby restoring the release rod 21 to its initial position.

[0112] It is understandable that, since the pawl 11 and the release lever 21 rotate coaxially, the pawl reset elastic element 12 and the release lever reset elastic element 22 can use the same set of reset elastic elements that cooperate with the base plate 30, so as to save related parts.

[0113] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the left and right rudder integrated front hatch locking device 100 of the present invention further includes a pop-up mechanism 40. The pop-up mechanism 40 includes a pop-up rod 41 and a pop-up elastic element 42. A lifting part 411 is provided on the pop-up rod 41. The pop-up rod 41 is configured to be controlled by the elastic force of the pop-up elastic element 42, and the lifting part 411 lifts the latch 200 along the third direction P.

[0114] In the use of the integrated left and right rudder hood locking device 100 of the present invention, after the device is unlocked, the latch 200 on the hood moves out of the locking slot 311, and the pop-up lever 41 is controlled by the elastic force of the pop-up elastic member 42. The lifting part 411 lifts the latch 200, thereby creating a gap between the hood and the engine compartment, making it easier for the user to lift the hood. During the process of the user lowering the hood and pressing it down, the integrated left and right rudder hood locking device 100 switches from a half-lock state to a half-lock state, and then to a fully locked state. The lifting part of the pop-up lever 41 moves downward continuously under the user's downward pressure.

[0115] It is understood that any one of the aforementioned ratchet reset elastic element 14, pawl reset elastic element 12, release rod reset elastic element 22, connecting rod reset elastic element 24, and spring-loaded elastic element 42 may be a torsion spring or other type of elastic element, and no restriction is imposed here.

[0116] like Figure 1 As shown, in one embodiment of the present invention, the left and right rudder integrated front hatch locking device 100 of the present invention further includes a detection sensor 50, which is configured to cooperate with the ratchet 13 to output a corresponding signal when the ratchet 13 is disengaged from the fully locked position.

[0117] Specifically, such as Figure 1 As shown, in this embodiment, the detection sensor 50 includes a micro switch 51. When the ratchet 13 is in a fully locked state, it contacts the micro switch 51. When the ratchet 13 disengages from the fully locked state and disengages from the micro switch 51, the micro switch 51 outputs a corresponding signal, allowing the device or user of the integrated left and right rudder front canopy locking device 100 to determine whether the device is in a fully locked state. In other embodiments of the present invention, the specific form and operating state of the detection sensor 50 can be set as needed and are not limited here.

[0118] In summary, as Figure 8A As shown, before the left and right rudder integrated front hatch locking device 100 of the present invention is locked, the pawl 11 and the ratchet 13 are in a fully open state. Figure 8B As shown, during the first locking process of the left and right rudder integrated front hatch locking device 100 of the present invention, the latch 200 can push the ratchet 13 to rotate in the second rotation direction N, thereby driving the pawl engagement part 112 to move to abut against the first engagement part 131 of the ratchet to enter a semi-locked state, while simultaneously pressing down the pop-up lever 41. Figure 8C As shown, during the second locking process of the integrated left and right rudder front canopy locking device 100 of the present invention, the latch 200 can continue to push the ratchet 13 to rotate in the second rotation direction N, causing the pawl engagement part 112 to move to abut against the second engagement part 132 of the ratchet, so as to enter the fully locked state, thereby realizing the locking of the latch 200. At the same time, the pop-up lever 41 is further pressed down. It can be understood that during the locking process of the integrated left and right rudder front canopy locking device 100 of the present invention, the release lever 21 and the connecting lever 23 do not move at all.

[0119] like Figure 9A As shown, before the left and right rudder integrated front hatch locking device 100 of the present invention is unlocked, the pawl 11 and the ratchet 13 are in a fully locked state, thereby locking the latch 200 onto the left and right rudder integrated front hatch locking device 100; the release rod 21 and the connecting rod 23 are both in their initial positions, and the connecting rod limiting part 233 abuts against the first limiting part 32 on the bottom plate 30.

[0120] like Figure 9B As shown, when the user needs to unlock the integrated left and right rudder front hatch locking device 100 of the present invention, by directly or indirectly pulling the release lever 21, the release lever 21 can rotate from its initial position along the first rotation direction M, thereby driving the connecting rod 23 to rotate from its initial position. At this time, the connecting rod 23 is controlled by the connecting rod reset elasticity to rotate a certain angle along the second rotation direction N, until... Figure 9C As shown, the second mating part 232 of the connecting rod is in contact with the pawl abutment part 111.

[0121] At this time, as Figure 9D As shown, the release lever 21 can continue to drive the connecting rod 23 to rotate as a whole in the first rotation direction M. The first mating part 231 of the connecting rod 23 can then abut against the pawl abutment part 111, thereby pushing the pawl locking part 112 to separate from the ratchet second mating part 132, as shown. Figure 9E As shown, ratchet 13 rotates in the first direction under the action of ratchet reset elastic element 14, and the first mating part 131 of the ratchet abuts against the pawl engaging part 112, so that the pawl 11 and ratchet 13 are in a semi-locked state. After switching to the semi-locked state, the user releases the release lever 21, as shown. Figure 9FAs shown, both the release lever 21 and the connecting lever 23 return to their initial positions.

[0122] Then, as Figure 9G As shown, in the half-locked state, when the user pulls the release lever 21 again, causing it to rotate again from its initial position along the first rotation direction M, the connecting rod 23 rotates from its initial position again. At this time, the side of the first mating part 231 of the connecting rod abuts against the second limiting part 213 on the release lever 21, and then... Figure 9H As shown, the connecting rod 23 is driven by the release rod 21, causing the second mating part 232 of the connecting rod to abut against the pawl abutment part 111. Further, as... Figure 9I As shown, the second mating part 232 of the connecting rod pushes the pawl engaging part 112 to separate from the first mating part 131 of the ratchet, and the pawl 11 and the ratchet 13 are in the fully open state, thereby releasing the lock 200. And as... Figure 9J As shown, when the device is in the fully open state, if the user releases the release lever 21 again, both the release lever 21 and the connecting lever 23 will return to their initial positions in preparation for the next unlocking.

[0123] Throughout the unlocking process, the pop-up lever 41 is always controlled by the elastic force of the pop-up elastic element 42, and the lifting part 411 lifts the lock 200.

[0124] When the aforementioned left and right rudder integrated hood locking device 100 is applied to a car, it is installed in the front engine compartment of the car and is configured to be locked with the latch 200 on the hood in a fully locked or half-locked state, and to release the latch 200 on the hood in a fully open state.

[0125] When the hood needs to be unlocked, the user only needs to pull the handle corresponding to the left and right hood integrated locking device 100 of the present invention twice to unlock the hood of the car. This eliminates the need for the user to unlock the hood from inside the car and then go outside to unlock the safety hook, providing a convenient and quick operating experience. During the process of the user lowering and pressing down on the hood, the left and right hood integrated locking device 100 switches from a half-locked state to a half-locked state, and then to a fully locked state, thereby locking the latch 200 on the hood into the locking stop 311 of the left and right hood integrated locking device 100 of the present invention, thus locking the hood of the car.

[0126] Furthermore, in one embodiment of the present invention, a handle is provided on the left or right side of the vehicle. The handle is configured to be connected to the pull rope of the left and right hood locking device 100. When the handle is provided on the left side of the vehicle, the pull rope is fixed to one of the first pull part 211 and the second pull part 212. When the handle is provided on the right side of the vehicle, the pull rope is fixed to the other of the first pull part 211 and the second pull part 212.

[0127] Understandably, since cars are divided into left-hand drive and right-hand drive, meaning the driver's seat is located on the left and right sides of the vehicle, the hood handle is usually located near the driver's side to facilitate unlocking the hood.

[0128] Thus, when the handle is in Figure 1 When the handle is on the right side, the pull rope can be fixed to the first pull part 211. Thus, when the user pulls the handle, thereby pulling the pull rope to the right, the release lever 21 will rotate along the first rotation direction M, unlocking the left and right rudder integrated front hatch locking device 100 of this invention. When the handle is in the right position... Figure 1 When the handle is on the left side, the pull rope can be fixed to the second pull part 212. In this way, when the user pulls the handle and pulls the pull rope to move to the left, the release lever 21 can also be rotated along the first rotation direction M, thereby unlocking the left and right rudder integrated front hatch locking device 100 of the present invention.

[0129] It can be seen that regardless of whether the car is left-hand drive or right-hand drive, there is no need to adjust the setting direction of the integrated left-hand drive hood lock device 100, nor is it necessary to prepare two sets of mirror images of the integrated left-hand drive hood lock devices 100 for left-hand drive and right-hand drive cars. Furthermore, when the integrated left-hand drive hood lock device 100 of this invention is applied to left-hand drive and right-hand drive cars, it can maintain the same arrangement position and direction. Designers only need to adjust the fixed position of the pull rope on the release lever 21 according to the handle's setting position. This allows for the simultaneous unlocking function of both left-hand drive and right-hand drive cars using a single release lever 21, without requiring technicians to make other adjustments to the integrated left-hand drive hood lock device 100 for left-hand drive and right-hand drive cars. This significantly reduces the development cost of changing a left-hand drive car to a right-hand drive version or vice versa, and also saves material costs associated with preparing different integrated left-hand drive hood lock devices 100 for left-hand drive and right-hand drive cars respectively.

[0130] It is understood that when the first pulling part 211 and the second pulling part 212 are in symmetrical positions relative to the rotation axis O of the release lever, it can be ensured that the operating stroke of the left and right rudder integrated hood lock device 100 of the present invention is the same in both left-hand drive and right-hand drive vehicles, thereby improving the user experience.

[0131] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
