[0030] See also Figure 1-Figure 3 As shown, this embodiment provides an integrated actuator for a car door lock, comprising a base, an active member arranged on the base, a driven member, and a return assembly for driving the active member to return;

[0031] The active member is hinged to the base, the driven member is hinged to the base, and the driving shafts of the active member and the driven member are arranged in parallel, the active member and the driven member are in pressing contact, and one of the driven members is a locking tongue;

[0032] The active member includes an input member, a plurality of output members, and a locking mechanism for controlling the combination and separation of the input member and the output member. The input member and the output member are sleeved on the same rotating shaft. The input member has a power input end, and the output member and the driven member are correspondingly arranged.

[0033] The input part includes an external opening active part, the output part includes a secondary lock transmission part and a main lock transmission part, the driven part includes a secondary lock driving part and a main lock lock tongue 7, the external opening active part is connected to the external opening pull wire, the main lock transmission part is in pressure contact with the main lock lock tongue 7, the secondary lock transmission part is in pressure contact with the secondary lock driving part, and the secondary lock driving part is connected to the secondary lock through the secondary lock pull wire.

[0034] It can be seen that the integrated actuator for a car door lock provided in this embodiment includes a base, an active member, a driven member and a return assembly; the active member and the driven member are hinged to the base, which allows the active member and the driven member to achieve flexible rotation on the base, thereby executing the opening and closing functions of the door lock; the driving shafts of the active member and the driven member are arranged in parallel to ensure the synchronization and accuracy of the action; the active member and the driven member are in pressing contact, so that the action of the active member can be directly transmitted to the driven member, thereby realizing the corresponding operation of the door lock.

[0035] It can be seen that the active part includes an input part, multiple output parts and a locking mechanism, which enables the active part to control the actions of multiple output parts at the same time, thereby realizing synchronous operation of different parts of the door lock; the input part and the output part are mounted on the same rotating axis, ensuring the stability and reliability of the movement relationship between them; the power input end on the input part can be connected to an external operating device, such as a door handle or a remote control key, so as to receive instructions to open or close the door lock.

[0036] It can be seen that the input part includes an outward opening active part, and the output part includes a secondary lock transmission part and a main lock transmission part, so that the door lock can simultaneously drive the main lock and the secondary lock to perform corresponding actions when performing an opening or closing action; the follower includes a secondary lock driving part and a main lock lock tongue 7, and the secondary lock driving part and the main lock lock tongue 7 are respectively pressed and contacted with the secondary lock transmission part and the main lock transmission part, ensuring the transmission and execution of the action; the secondary lock driving part is connected to the secondary lock through a secondary lock pull wire, which can make the operation of the secondary lock more convenient and reliable.

[0037] It can be seen that the return assembly can drive the active part to return, so that the door lock can automatically return to its initial state after completing the opening or closing action, ready for the next operation. This not only improves the convenience of using the door lock, but also extends its service life.

[0038] Specifically, the power input end includes a motor 1 arranged on the base, the output shaft of the motor 1 is connected to a worm 2, the worm 2 is meshed with a bevel gear 3, the bevel gear 3 is sleeved on a rotating shaft on the base, and the rotating shaft is also sleeved with a gear 4, and the gear 4 realizes the locking and unlocking of the locking mechanism through a locking rod 5.

[0039] It can be seen that a complete power transmission system is formed by the motor 1 arranged on the base, the worm 2 connected to the output shaft of the motor 1, the bevel gear 3 meshing with the worm 2, and the gear 4 on the rotating shaft, thereby driving the active part to perform the opening and closing actions of the door lock, which makes the action of the door lock more precise and reliable and improves the use effect; the meshing method of the bevel gear 3 and the worm 2 can effectively reduce the noise and vibration in the transmission process and improve the comfort of using the door lock.

[0040] It can be seen that the setting of the locking rod 5 enables the locking mechanism to realize the functions of locking and unlocking, thereby controlling the combination and separation of the input member and the output member. When the door lock action needs to be executed, the locking mechanism is unlocked, and the power of the input member can be transmitted to the output member through the gear 4, driving the driven member to perform the corresponding action; and when the door lock is in the locked state, the locking mechanism is locked, which can effectively prevent the influence of external interference or misoperation on the door lock, thereby improving the safety performance of the door lock.

[0041] Specifically, the return assembly includes a torsion spring 6 sleeved on the rotating shaft, one end of the torsion spring 6 is connected to the base, and the other end of the torsion spring 6 is connected to the active member.

[0042] It can be seen that the return assembly includes a torsion spring 6 sleeved on the rotating shaft, and the torsion spring 6 can use its own elastic potential energy to drive the active member to return. When the active member completes the opening or closing action of the door lock, the elastic potential energy of the torsion spring 6 will push the active member to return to the initial position, so that the door lock remains in a stable state, providing convenience for the next operation; the use of the torsion spring 6 also makes the structure of the return assembly simple and reliable, reducing the maintenance cost of the door lock.

[0043] It can be seen that one end of the torsion spring 6 is connected to the base, and the other end is connected to the active member, which can ensure that the elastic potential energy of the torsion spring 6 can directly act on the active member, thereby effectively driving the active member to return.

[0044] Specifically, the pressing contact between the active member and the driven member is driven by a gear 4, a cam or a ratchet.

[0045] It can be seen that the gear 4 transmission can achieve a precise rotation ratio and rotation direction between the input and output parts, and is suitable for situations where the door lock action needs to be precisely controlled. The gear 4 transmission has a compact structure and high transmission efficiency, and can meet the performance and reliability requirements of the door lock; the cam transmission can achieve complex motion trajectories and action sequences, and is suitable for situations where specific actions need to be achieved in the door lock. By reasonably designing the profile of the cam and the shape of the follower, a smooth transition and precise positioning can be achieved during the opening and closing of the door lock. The cam transmission also has the advantages of simple structure, easy processing and maintenance, which reduces the manufacturing cost and maintenance difficulty of the door lock; the ratchet transmission is suitable for door lock systems that need to achieve unidirectional transmission or intermittent transmission. The ratchet transmission can ensure that the active part drives the driven part to move in a specific direction, but cannot transmit power in the opposite direction, thereby realizing the unidirectional locking function of the door lock. The ratchet transmission also has the characteristics of simple structure, easy operation and maintenance, making the use of the door lock more convenient and safe.

[0046] It can be understood that the form of pressing contact between the active member and the driven member can be flexibly selected according to the specific needs and design of the door lock to achieve optimal performance and reliability. Whether it is gear 4 transmission, cam transmission or ratchet transmission, it can provide the door lock with a stable and reliable power transmission and action execution mechanism to ensure the normal operation and use effect of the door lock.

[0047] Specifically, the locking mechanism includes a locking rod 5, a first matching hole located on the outward opening active part, a through hole located on the secondary lock transmission part, and a second matching hole located on the main lock transmission part. One end of the locking rod 5 is hinged to the rotating shaft, and the other end of the locking rod 5 matches with the first matching hole, the second matching hole, and the through hole.

[0048] It can be seen that the locking mechanism realizes precise control of the combination and separation between the input member and the output member through the cooperation of the locking rod 5 with different matching holes. When the locking rod 5 cooperates with the first matching hole, the second matching hole, and the through hole, the locking structure is in an unlocked state; when the locking rod 5 is disengaged from the first matching hole, the locking mechanism is in a locked state.

[0049] It can be understood that through the above design, it can be ensured that when the door lock is opening or closing, the power of the input part can be smoothly transmitted to the output part, thereby driving the driven part to complete the corresponding action; and when the door lock is in a locked state, the locking mechanism can effectively prevent the power transmission between the input part and the output part, and prevent external interference or misoperation from affecting the door lock, which not only improves the safety performance of the door lock, but also ensures the stability and reliability of the door lock.

[0050] Specifically, the main lock transmission component includes a pawl transmission arm, a pawl 8 fixedly connected to the pawl transmission arm and having the same rotation axis, the pawl transmission arm, the outward opening active component, the auxiliary lock transmission component, and the auxiliary lock driving component are located on one side of the base, and the pawl 8 is located on the other side of the base, and the pawl 8 is pressed and contacted with the main lock tongue 7.

[0051] It is understandable that the design of the main lock transmission element fully considers the practicality and safety of the door lock. The fixed connection between the pawl transmission arm and the pawl 8 ensures the synchronization of the two during the action process, thereby realizing the precise control of the main lock tongue 7; the pressing contact between the pawl 8 and the main lock tongue 7 ensures the stability of the door lock in the closed state, preventing the door lock from being accidentally opened due to external factors.

[0052] It can be seen that the pawl transmission arm, the external opening active component, the auxiliary lock transmission component and the auxiliary lock driving component are located on one side of the base, while the pawl 8 is located on the other side, which makes the structural layout of the door lock more compact and also facilitates the assembly and maintenance of parts.

[0053] Specifically, the integrated actuator for the automobile door lock also includes a left tailgate outside opening handle, a right tailgate outside opening handle, a secondary lock driving mechanism connected to the left tailgate outside opening handle, a main lock connected to the right tailgate outside opening handle, a secondary lock connected to the main lock, and two secondary locks connected to the secondary lock driving structure.

[0054] It can be seen that the integrated actuator for the automobile door lock provided in this embodiment is convenient and safe to operate. The provision of the left tailgate outer opening handle and the right tailgate outer opening handle allows the user to conveniently control the opening of the tailgate from both sides, thus improving the convenience of use; the auxiliary lock driving mechanism realizes the precise control of the auxiliary lock, thus ensuring the stability and safety of the tailgate in the closed state; the coordinated use of the main lock and the auxiliary lock enhances the anti-theft performance of the door lock, thus preventing unauthorized opening.

[0055] Specifically, the integrated actuator for the automobile door lock also includes a main lock, which is used to connect the left tailgate and the right tailgate, and a secondary lock which is used to connect the tailgate and the vehicle body.

[0056] Specifically, the integrated actuator for the automobile door lock also includes a right tailgate inner opening handle, and the right tailgate inner opening handle is connected to the active component of the main lock.

[0057] It can be seen that the right tailgate inner opening handle is connected to the active part of the main lock. The user can drive the active part of the main lock to move by pulling the right tailgate inner opening handle, thereby realizing the opening action of the tailgate. This is not only easy to operate, but also can effectively reduce the user's operating steps and time, and improve the convenience of use.

[0058] Specifically, the integrated actuator for the automobile door lock also includes a shell located on the outside of the base and wrapping the base, and a silencer component is arranged in the shell, and the silencer component includes a honeycomb silencer tube and sound-absorbing material.

[0059] It can be seen that the setting of the shell can protect the internal components and enhance the overall structural stability of the door lock; the silencer component effectively reduces the noise generated by the door lock during operation and improves the user experience; the combination of honeycomb silencer and sound-absorbing material makes the silencer effect more significant and also makes the door lock's silent performance more outstanding.

[0060] In summary, the integrated actuator for automobile door locks provided in this embodiment has the characteristics of compact structure, convenient operation, safety and reliability, and excellent quiet performance. The integrated actuator for automobile door locks provided in this embodiment realizes the integration and simplification of door lock functions through integrated design, reduces manufacturing costs and maintenance difficulties; by accurately controlling the combination and separation between the input and output parts, and adopting advanced transmission methods and silencer technologies, it ensures the stability and reliability of the door lock when performing opening or closing actions, and improves the user experience.
