Description

Technical Field

[0001] This utility model relates to the field of automotive electric door lock technology, and in particular to an automotive door lock with a super lock. Background Technology

[0002] As a crucial component of automotive safety systems, car door locks have evolved from traditional mechanical locks to electric locks, and now to complex systems integrating multiple intelligent functions. Currently, car door locks are mainly classified into three categories: mechanical locks, ordinary electric locks, and super locks.

[0003] Mechanical locks were the earliest form of door locks, requiring manual operation to lock and unlock, such as reed locks, hook locks, and latch locks. These locks have a simple structure, but they have poor longitudinal load-bearing capacity, low security, and are noisy and prone to wear during use.

[0004] Ordinary electric locks use electric controls to achieve locking, unlocking, and child lock functions, offering significant improvements in convenience and security compared to mechanical locks. A typical electric lock consists of a lock body, internal and external opening mechanisms, internal and external locking / unlocking mechanisms, and components such as lock pins / latches / stops. Its working principle involves an electric motor driving gears to rotate, thus opening and closing the lock.

[0005] Super locks add extra security features to ordinary electric locks, maintaining a locked state even without a key or remote control to prevent internal opening. Through a complex mechanical structure and electronic control system, super locks achieve enhanced security.

[0006] Despite significant progress in automotive door lock technology, some problems and shortcomings still exist, mainly in the following aspects:

[0007] 1. Low functional integration:

[0008] Existing automotive door lock systems often use multiple independent components to achieve different functions, such as electric unlocking, central locking and release, and superlock locking and unlocking. This design not only increases production costs and installation complexity, but also makes the system prone to failure points due to the coordinated operation of multiple components, affecting the system's reliability and stability.

[0009] 2. Complex operation:

[0010] Because the functions are distributed across multiple components, users need to control different switches or buttons separately when operating the door lock, making the operation cumbersome and unintuitive. This not only degrades the user experience but may also lead to safety hazards due to misoperation.

[0011] 3. Insufficient security and reliability:

[0012] While superlocks offer improved security, their complex designs increase the risk of malfunction. Furthermore, some superlocks may fail to unlock quickly in emergencies, hindering passenger escape and rescue efforts.

[0013] 4. Poor adaptability and flexibility:

[0014] Different car models and door structures have different requirements for door lock systems. Existing door lock systems are often unable to meet diverse needs, forcing automakers to customize different door lock systems during the design and production process, increasing costs and time investment.

[0015] Therefore, this application is hereby submitted. Utility Model Content

[0016] In view of this, this utility model proposes a car door lock with a super lock, aiming to solve the technical problems of existing car door lock systems in terms of functional integration, structural complexity, and reliability. Traditional car door locks are usually composed of multiple independent components, resulting in system complexity, high production costs, and difficult maintenance, while also increasing potential points of failure and affecting user experience.

[0017] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0018] A car door lock with a superlock, comprising:

[0019] The door lock mechanism includes an electrically operated release lever, an electrically operated release auxiliary lever, and a release lever, wherein the release lever can be driven by a drive device to rotate and open the door lock;

[0020] The central locking mechanism includes an external locking link, which, under the action of the driving device, engages or disengages the electrically operated release rod from the electrically operated release auxiliary rod.

[0021] The super lock mechanism includes a super lock link, which can be directly or indirectly driven to rotate by the drive device, thereby locking or unlocking the inner locking auxiliary rod. When the inner locking auxiliary rod is in the locked position, the inner release lever and the inner locking auxiliary rod pull-unlock function are disabled.

[0022] The driving device includes an electric opening gear, which, when rotating, can perform an electric opening function, a switching function between the central locking and unlocking states of the central locking mechanism, and a switching function between the locking and unlocking states of the super lock mechanism.

[0023] Furthermore, when the electrically operated gear rotates, it can drive the external locking linkage to slide or rotate, thereby engaging or disengaging the electrically operated release rod from the electrically operated release auxiliary rod.

[0024] Furthermore, the electrically operated release rod is provided with a rotating shaft, and a release locking clutch spring is provided on the rotating shaft. The release locking clutch spring can connect the electrically operated release rod and the electrically operated release auxiliary rod as one unit. The outer locking link drives the extension end of the release locking clutch spring to move away from the electrically operated release auxiliary rod through horizontal movement or rotation, and separates the electrically operated release rod from the electrically operated release auxiliary rod.

[0025] Furthermore, a first limiting baffle is provided on the rotating shaft, and a second limiting baffle is provided on the electric switch release auxiliary rod. A clutch groove is formed between the first limiting baffle and the second limiting baffle, and a misalignment groove is formed between the second limiting baffle and the first limiting baffle in the inward and outward directions.

[0026] Furthermore, a first connecting part and a first limiting rod are provided on the outer locking link. The first connecting part and the first limiting rod are located on opposite sides of the rotating shaft. When the first limiting rod slides horizontally with the outer locking link, it can push outward to separate the electrically released rod from the electrically released auxiliary rod.

[0027] Furthermore, an external release auxiliary rod is hinged and fixed to the external locking link. The external release auxiliary rod can be driven to rotate by the external release pull rod. When the external locking link is driven to the central locking state by the electric opening gear, the external release auxiliary rod is pulled to one side by the external locking link. When the external release pull rod is driven to rotate, it disengages from the external release auxiliary rod. When the external locking link is driven to the central unlocking state by the electric opening gear, the external release pull rod can drive the external release auxiliary rod to rotate when it rotates, thereby driving the release rod to rotate and open the door lock.

[0028] Furthermore, a locking lever auxiliary rod is provided on the electric opening gear. The locking lever auxiliary rod includes a first transmission link and a second transmission link. When the second transmission link rotates with the electric opening gear, it can drive the outer locking link to slide. When the first transmission link rotates with the electric opening gear, it can drive the super lock link to rotate through the super lock release auxiliary rod.

[0029] Furthermore, the first transmission link and the second transmission link are connected at an angle and are located at the shaft of the electric gear. The first transmission link is located in the counterclockwise direction of the second transmission link, and the locking lever auxiliary rod is provided with a first return spring at its shaft.

[0030] Furthermore, a guide transmission flange is provided on the electric opening gear. When the guide transmission flange rotates counterclockwise with the electric opening gear, it can drive the locking lever auxiliary rod to rotate counterclockwise. When the guide transmission flange rotates clockwise with the electric opening gear, it can drive the second limiting flange provided on the cantilever end of the electric opening release rod to rotate clockwise, or it can drive the electric opening release rod and the locking lever auxiliary rod to rotate clockwise.

[0031] Furthermore, the super lock release auxiliary rod is hinged to the first transmission link, the super lock link is located diagonally above the locking lever auxiliary rod, and a third return spring for self-resetting is provided at the connection between the inner locking auxiliary rod and the electric release auxiliary rod.

[0032] Compared with existing technologies, the car door lock with super lock described in this utility model has the following advantages:

[0033] (1) The car door lock with super lock described in this utility model integrates the electric opening mechanism, central locking mechanism and super lock mechanism of the car door lock through a single drive device.

[0034] (2) The car door lock with super lock described in this utility model ensures the coordinated work between various components by introducing a locking lever auxiliary rod and a variety of spring mechanisms. The clutch mechanism design between the electric release lever and the electric release auxiliary rod enables the door lock to switch quickly and smoothly in different states, avoiding noise and wear caused by mechanical friction and improving the user's operating experience.

[0035] (3) The car door lock with super lock described in this utility model reduces the number of components, simplifies the structure, reduces production and maintenance costs, and improves the stability of the system, making the door lock operation more convenient and smooth, and meeting the needs of modern consumers for car safety and intelligence.

[0047] like Figures 1-4 As shown, this application discloses a car door lock with a super lock, comprising:

[0048] The door lock mechanism includes an electrically operated release lever 2, an electrically operated release auxiliary lever 3, and a release lever 14, wherein the release lever 14 can be driven by a drive device to rotate and open the door lock.

[0049] The central locking mechanism includes an external locking link 1, which, under the action of the driving device, engages or disengages the electrically operated release rod 2 and the electrically operated release auxiliary rod 3.

[0050] The super lock mechanism includes a super lock link 21, which can be directly or indirectly driven to rotate by the drive device, thereby locking or unlocking the inner locking auxiliary rod 22. When the inner locking auxiliary rod 22 is in the locked position, the inner release lever 23 and the inner locking auxiliary rod 22 are ineffective in their pull-unlocking function.

[0051] The driving device includes an electric opening gear 12, which, when rotating, can perform the electric opening function, the switching function between the central locking and unlocking states of the central locking mechanism, and the switching function between the locking and unlocking states of the super lock mechanism.

[0052] This application discloses a car door lock with a super lock, the core of which lies in realizing multiple functions of the car door lock through a drive device including an electric opening gear 12. First: When the electric opening gear 12 receives a command to rotate, it can perform the electric opening function. In this condition, the electric opening gear 12 can drive the electric opening release rod 2 and the electric opening release auxiliary rod 3 to rotate synchronously, thereby pushing the release rod 14 to rotate and open the door lock. Second: When the electric opening gear 12 receives a command to rotate, it can perform the central locking or unlocking function of the central locking mechanism. Preferably, when the electric opening gear 12 rotates, it can drive the outer locking linkage 1 to slide or rotate, disengaging or reconnecting the electric opening release rod 2 and the electric opening release auxiliary rod 3. In this condition... The electrically operated gear 12 can drive the outer locking link 1 to slide or rotate. When the outer locking link 1 slides or rotates, if the electrically operated release rod 2 and the electrically operated release auxiliary rod 3 are disengaged, the central locking mechanism is in a central locking state. When the electrically operated gear 12 drives the electrically operated release rod 2 to rotate, the electrically operated release auxiliary rod 3 no longer rotates, that is, the release rod 14 will not work, and the door will not be opened, thus achieving central locking. When the outer locking link 1 slides or rotates, if the electrically operated release rod 2 and the electrically operated release auxiliary rod 3 are disengaged... When connected, the central locking mechanism is in the central locking / unlocking state. When the electric unlocking gear 12 drives the electric unlocking release rod 2 to rotate, it can also drive the electric unlocking release auxiliary rod 3 to rotate, thereby pushing the release rod 14 to rotate and open the door lock, thus switching to central locking / unlocking. Third: When the electric unlocking gear 12 receives a command to rotate, it can execute the locking and unlocking functions of the super lock mechanism. In this condition, the electric unlocking gear 12 can directly or indirectly drive the super lock connecting rod 21 to rotate, thereby locking or unlocking the inner locking auxiliary rod 22 connected to the electric unlocking release auxiliary rod 3. When the inner lock is engaged... When the inner locking auxiliary rod 22 is in the locked position, the inner locking auxiliary rod 22 is limited by the super lock linkage 21, and the inner release lever 23 connected to it will lose the function of pulling the inner locking auxiliary rod 22 to unlock, ensuring the high security of the door lock in the super lock state. When the electric opening gear 12 drives the super lock linkage 21 to rotate to the unlock position, the inner locking auxiliary rod 22 is relatively disengaged from the super lock linkage 21. At this time, pulling the inner release lever 23 will drive the inner locking auxiliary rod 22 and the electric opening release auxiliary rod 3 to rotate together, thereby pushing the release lever 14 to rotate and open the door lock.

[0053] The car door lock with superlock disclosed in this application integrates the electric opening mechanism, central locking mechanism and superlock mechanism of the car door lock into a single drive device. It realizes three key functions—electric opening, central locking and release, and superlock locking and unlocking—with only one electric opening gear 12. This greatly reduces production costs and installation complexity, improves the reliability and stability of the door lock system, reduces potential failure points caused by the collaborative work of multiple components, optimizes the user experience, makes the operation of the door lock simpler and faster, and enhances the intelligence and security level of the entire vehicle.

[0054] As a preferred example of this application, an external release auxiliary rod 25 is hinged and fixed to the external locking link 1. The external release auxiliary rod 25 can be driven to rotate by the external release pull rod 24 and can be pulled to one side by the external locking link 1. When the external locking link 1 is driven to the central locking state by the electric opening gear 12, the external release auxiliary rod 25 is pulled to one side by the external locking link 1. When the external release pull rod 24 is driven to rotate, it disengages from the external release auxiliary rod 25. When the external locking link 1 is driven to the central unlocking state by the electric opening gear 12, the external release pull rod 24 can drive the external release auxiliary rod 25 to rotate when rotating, thereby driving the release rod 14 to rotate and open the door lock. This invention discloses a specific method for the failure of the external locking mechanism when a car door lock is in a centrally locked state. In the example of this application, the external locking linkage 1 can be driven to slide to the right in the centrally locked state. The external release auxiliary rod 25 is located at the left end of the external locking linkage 1. When the external locking linkage 1 slides to the right, it simultaneously drives the external release auxiliary rod 25 to slide to the right as a whole, thereby causing the external release auxiliary rod 25 to disengage from the external release lever 24. At this time, even if the external release lever 24 is pulled to rotate, it cannot drive the external release auxiliary rod 25 to rotate, and thus cannot drive the release lever 14 to rotate and open the door lock. However, when the external locking linkage 1 is located on the left side in the centrally locked state, the external release lever 24 and the external release auxiliary rod 25 are connected to each other. When the external release lever 24 is pulled to rotate, it drives the external release auxiliary rod 25 to rotate, and thus drives the release lever 14 to rotate and open the car door lock as a whole.

[0055] This setup, through precise mechanical linkage design, effectively prevents external interference in the central locking state, simplifies the door lock structure, reduces potential failure points, improves system reliability and stability, thereby reducing production and maintenance costs, enhancing the overall vehicle intelligence level, and meeting modern consumers' dual needs for automotive safety and convenience.

[0056] As a preferred example of this application, a locking lever auxiliary rod 13 is provided on the electrically operated gear 12. The locking lever auxiliary rod 13 includes a first transmission link 17 and a second transmission link 18. When the second transmission link 18 rotates with the electrically operated gear 12, it can drive the outer locking link 1 to slide. When the first transmission link 17 rotates with the electrically operated gear 12, it can drive the super lock link 21 to rotate through the super lock release auxiliary rod 20. This setup incorporates a locking lever auxiliary rod 13, including a first transmission link 17 and a second transmission link 18, onto the electric opening gear 12. When the electric opening gear 12 rotates, the second transmission link 18 drives the outer locking link 1 to slide during the rotation of the electric opening gear, thereby realizing the locking or releasing function of the central locking system. Simultaneously, the first transmission link 17 drives the super lock link 21 to rotate through the super lock release auxiliary rod 20. This linkage mechanism enables the electric opening gear 12 not only to control the opening and closing of the door lock but also to effectively switch the state of the super lock, ensuring that all parts of the door lock system can work in coordination under different operating modes, thereby improving the overall performance and security of the system.

[0057] By introducing the design of the locking lever auxiliary rod 13, the electric opening gear 12 becomes more versatile and flexible, enabling dual control of the external locking linkage 1 and the super lock linkage 21 within a single device. This simplifies the structure of the door lock system, reduces the number of components, thereby lowering production and maintenance costs. It also improves system reliability, reduces potential failure points, and optimizes the user experience.

[0058] As a preferred example of this application, the electrically operated release rod 2 is provided with a rotating shaft 11, and a release locking clutch spring 4 is provided on the rotating shaft 11. The release locking clutch spring 4 can connect the electrically operated release rod 2 and the electrically operated release auxiliary rod 3 into one unit. The outer locking link 1 drives the extension end of the release locking clutch spring 4 to move away from the electrically operated release auxiliary rod 3 through horizontal movement or rotation, and separates the electrically operated release rod 2 from the electrically operated release auxiliary rod 3. This design, by incorporating a rotating shaft 11 and a release lock clutch spring 4 on the electrically operated release rod 2, effectively connects and separates the electrically operated release rod 2 from the electrically operated release auxiliary rod 3. The working principle is as follows: the release lock clutch spring 4 on the rotating shaft 11 connects the electrically operated release rod 2 and the electrically operated release auxiliary rod 3 as a single unit. When the outer locking link 1 moves horizontally or rotates, the extension end of the release lock clutch spring 4 moves away from the electrically operated release auxiliary rod 3, thus separating the electrically operated release rod 2 from the electrically operated release auxiliary rod 3. When the outer locking link 1 resets under the action of the electrically operated gear 12 and the second transmission link 18, the release lock clutch spring 4 resets and connects the electrically operated release rod 2 and the electrically operated release auxiliary rod 3 as a single unit, thereby enabling the switching between the central locking and unlocking states of the central locking mechanism, ensuring efficient response and convenient operation of the door lock system.

[0059] By cleverly designing the aforementioned spring clutch locking mechanism, the internal structure of the car door lock is simplified, reducing manufacturing and maintenance costs. This also enhances the lock's durability and reliability. The synergistic effect of the external locking linkage and the release locking clutch spring makes the switching between central locking and release smoother, improving the user experience. Users can quickly unlock or lock the door when needed, thus improving the overall security and stability of the car door lock. Furthermore, this design can adapt to the needs of different car models and door structures, providing automakers with a flexible and efficient door lock solution, thereby gaining a more advantageous position in market competition.

[0060] As a preferred example of this application, a first limiting baffle 8 is provided on the rotating shaft portion 11, and a second limiting baffle 10 is provided on the electrically operated release auxiliary rod 3. A clutch groove 9 is formed between the first limiting baffle 8 and the second limiting baffle 10. The second limiting baffle 10 and the first limiting baffle 8 form a misalignment groove in the inward and outward directions, which is used to separate the electrically operated release rod 2 from the electrically operated release auxiliary rod 3 when the release locking clutch spring 4 is pushed outward by the first limiting rod 7. Preferably, the length of the second limiting baffle 10 in the inward and outward directions is less than the length of the first limiting baffle 8 in the inward and outward directions. By setting a first limiting baffle 8 and a second limiting baffle 10 on the rotating shaft 11 and the electrically operated release auxiliary rod 3 respectively, a clutch groove 9 is formed between them to accommodate the extension end of the limiting release locking clutch spring 4. When the extension end of the release locking clutch spring 4 is inside the clutch groove 9, the electrically operated release rod 2 and the electrically operated release auxiliary rod 3 are connected as one unit; when the extension end of the release locking clutch spring 4 is outside the clutch groove 9, the electrically operated release rod 2 is disengaged from the electrically operated release auxiliary rod 3. By designing the length of the second limiting baffle 10 in the inward and outward directions to be less than the length of the first limiting baffle 8, when the release locking clutch spring 4 is pushed outward, the second limiting baffle 10 can more easily disengage from the clutch groove 9 due to the length difference, thereby achieving rapid and smooth disengagement of the electrically operated release rod 2 from the electrically operated release auxiliary rod 3.

[0061] This design further enables precise control of the clutch mechanism, making the disengagement of the electric release lever 2 and the electric release auxiliary lever 3 more stable and reliable, providing users with a smoother and more efficient user experience. At the same time, the length difference design makes the clutch mechanism easier to align and adjust during manufacturing and assembly, reducing production costs and difficulties.

[0062] As a preferred example of this application, a first connecting part 5 and a first limiting rod 7 are provided on the outer locking link 1, and the first connecting part 5 and the first limiting rod 7 are provided on opposite sides of the rotating shaft part 11.

[0063] Preferably, a first connecting groove 6 is provided on the first connecting part 5, and the electric release rod 2 can be driven to rotate by the electric opening gear 12. When the electric opening gear 12 rotates, it drives the locking lever auxiliary rod 13 to rotate. The locking lever auxiliary rod 13 extends into the first connecting groove 6 and drives the outer locking link 1 to slide horizontally to the left and right sides when the electric opening gear 12 rotates forward and backward. This configuration further defines the drive structure for the external locking linkage 1 to drive the release locking clutch spring 4 to switch between clutch engagement and disengagement. When the electrically operated release lever 2 is driven to rotate by the electrically operated gear 12, the electrically operated gear simultaneously drives the locking lever auxiliary lever 13 to rotate. One end of the locking lever auxiliary lever 13 extends into the first connecting groove 6 on the first connecting part 5. As the electrically operated gear 12 rotates forward and backward, the locking lever auxiliary lever 13 slides in the first connecting groove 6, and drives the external locking linkage 1 to slide horizontally to the left and right sides, thereby driving the release locking clutch spring 4 to switch between the central control locking state and the central control unlocking state, realizing the connection and separation of the electrically operated release lever 2 and the electrically operated release auxiliary lever 3.

[0064] This design enables precise control of the external locking linkage 1, improving the reliability and stability of the door lock. It also makes the locking and disengaging actions smoother and more fluid, reducing noise and wear caused by mechanical friction and extending the lock's lifespan. Furthermore, the coordinated use of the electric opening gear 12 and the locking lever auxiliary rod 13 drives the horizontal sliding of the external locking linkage 1, reducing the number of components and lowering the lock's production cost.

[0065] As a preferred example of this application, a guide transmission flange 16 is provided on the electrically operated gear 12. When the guide transmission flange 16 rotates counterclockwise with the electrically operated gear 12, it can drive the locking lever auxiliary rod 13 to rotate counterclockwise. When the guide transmission flange 16 rotates clockwise with the electrically operated gear 12, it can drive the second limiting flange 15 provided at the cantilever end of the electrically operated release rod 2 to rotate clockwise, or it can drive the electrically operated release rod 2 and the locking lever auxiliary rod 13 to rotate clockwise. In the example of this application, the first transmission link 17 and the second transmission link 18 are integrally connected at an angle and disposed at the shaft of the electrically operated gear 12. The first transmission link 17 is disposed in the counterclockwise direction of the second transmission link 18. When the guide transmission flange 16 rotates counterclockwise with the electrically operated gear 12, the guide transmission flange 16 pushes the first transmission link 17 to rotate counterclockwise, thereby driving the second transmission link 18 integrally connected with it to rotate counterclockwise, thereby driving the outer locking link 1 to slide to the right, thus performing the central locking operation; and when the central unlocking operation needs to be performed, When the electric unlocking gear 12 rotates clockwise, the locking lever auxiliary rod 13 resets under the action of a first return spring at its pivot. When the electric unlocking function needs to be executed, the guide transmission flange 16 rotates clockwise with the electric unlocking gear 12, pushing against the second limiting flange 15 and rotating clockwise, thereby driving the electric unlocking release rod 2 to rotate clockwise. At this time, the electric unlocking release rod 2 and the electric unlocking release auxiliary rod 3 are connected as one unit through a release locking clutch spring. The electric unlocking release auxiliary rod 3 rotates as one unit with the electric unlocking release rod 2, thereby driving the release rod 14 to rotate and unlock the door. When the electric unlocking gear 12 resets after unlocking, the guide transmission flange 16 on the electric unlocking gear 12 disengages from the second limiting flange 15, and the release rod 14 can be reset by the return torsion spring 19. The electric unlocking release auxiliary rod 3 and the electric unlocking release rod 2 rotate counterclockwise to return to the initial state, waiting for the next unlocking or central locking operation. Preferably, a second reset spring for resetting is provided at the pivot portion 11 of the electrically operated release lever 2, and a fourth reset spring for resetting is provided at the pivot portion of the electrically operated gear 12.

[0066] This design, by setting a guide transmission flange 16 on the electric opening gear 12, further optimizes the working mechanism of the car door lock, enabling the rotation of the electric opening gear to effectively control the movement of the locking lever auxiliary lever and the electric opening release lever, achieving efficient linkage of the door lock system, ensuring flexible switching of the door lock system in different states, and improving the smoothness and security of operation.

[0067] As a preferred example of this application, the super lock release auxiliary rod 20 is hinged to the first transmission link 17, the super lock link 21 is disposed diagonally above the locking lever auxiliary rod 13, preferably to the upper left, and a third return spring is provided at the connection between the inner locking auxiliary rod 22 and the electric opening release auxiliary rod 3.

[0068] When the superlock mechanism is locked, the first transmission link 17 is driven to rotate clockwise by the electric opening gear 12, the superlock release auxiliary rod 20 drives the superlock link 21 to rotate counterclockwise, and the superlock link 21 drives the inner locking auxiliary rod 22 to rotate clockwise when rotating counterclockwise, driving the inner locking auxiliary rod 22 and the electric opening release auxiliary rod 3 to the superlock locking position, and the inner release pull rod 23 disengages from the inner locking auxiliary rod 22 when it is pulled and rotated.

[0069] When the super lock mechanism is unlocked, the inner locking auxiliary rod 22 returns to the state of being connected to the inner release rod 23 under the action of the third return spring. When the inner release rod 23 is pulled, the inner locking auxiliary rod 22 and the electric release auxiliary rod 3 can rotate together, thereby pushing the release rod 14 to rotate and open the door lock.

[0070] This configuration defines the superlock mechanism of the car door lock with superlock described in this application. When the superlock mechanism is in the locked state, the electric opening gear 12 drives the first transmission linkage 17 to rotate clockwise, thereby driving the superlock release auxiliary rod 20 to move upward. The superlock linkage 21 then rotates counterclockwise, causing the inner locking auxiliary rod 22 to rotate clockwise. This drives the inner locking auxiliary rod 22 and the electric opening release auxiliary rod 3 together to the superlock locked position. At this time, the inner release lever 23 disengages from the inner locking auxiliary rod 22 when it is pulled and rotated, ensuring that the door lock is in the locked state. In the unlocked state, the third return spring causes the inner locking auxiliary rod 22 to return to the state of being connected to the inner release lever 23. Pulling the inner release lever 23 can drive the inner locking auxiliary rod 22 and the electric opening release auxiliary rod 3 to rotate together, ultimately pushing the release lever 14 to rotate and open the door lock. This series of actions ensures the efficiency and reliability of the superlock mechanism in the locking and unlocking process, and improves the security and flexibility of the door lock.

[0071] The car door lock with a superlock disclosed in this application is based on an integrated drive device via an electric opening gear 12, which enables efficient switching between multiple functions such as electric opening, central locking and release, and superlock locking and unlocking. The design incorporates a locking lever auxiliary rod 13 and various spring mechanisms to ensure coordinated operation between components, thereby enhancing the lock's security and reliability. This car door lock with a superlock reduces the number of components, simplifies the structure, lowers production and maintenance costs, improves system stability, avoids potential failure points caused by the coordinated operation of multiple components, optimizes the user experience, and makes door lock operation more convenient and smooth, meeting the modern consumer demand for automotive safety and intelligence.

[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
