-
The following describes the locking module 1 for the door lock mechanism according to the embodiment of the present disclosure with reference to the accompanying drawings.
-
As shown in FIG. 1 to FIG. 9, the locking module 1 for the door lock mechanism according to the embodiment of the present disclosure comprises a housing 10, a first movable arm 52, a fitting member 60, a driving assembly 70, and a second movable arm 51.
-
The door lock mechanism comprises a lock tongue assembly. The first movable arm 52 is rotatably arranged on the housing 10, and one end of the first movable arm 52 is suitable for cooperating with the lock tongue assembly, so that when the first movable arm 52 rotates and drives the lock tongue assembly to move, unlocking can be achieved. The fitting member 60 is arranged on the first movable arm 52 to drive the first movable arm 52 to rotate. The driving assembly 70 is arranged on the housing 10, and the driving assembly 70 cooperates with the fitting member 60 to drive the fitting member 60 to switch between an unlocked state and a locked state.
-
When the fitting member 60 is in the unlocked state, the fitting member 60 cooperates with the second movable arm 51. At this time, the second movable arm 51 drives the first movable arm 52 by means of the fitting member 60 to rotate, and the first movable arm 52 drives the lock tongue assembly to move, thereby achieving unlocking.
-
When the fitting member 60 is in the locked state, the fitting member 60 disengages from the second movable arm 51. At this time, when the second movable arm 51 is operated to move, the second movable arm 51 cannot drive the fitting member 60 to move, and thus cannot drive the first movable arm 52 to rotate through the fitting member 60. The first movable arm 52 cannot drive the lock tongue assembly to move, and unlocking cannot be achieved. In other words, when the fitting member 60 is in the locked state, the locking module 1 locks the door lock mechanism to prevent the door lock from being opened when the second movable arm 51 is accidentally touched, so as to provide better safety protection for children or other special users.
-
Specifically, when the door lock mechanism needs to be locked, the driving assembly 70 drives the fitting member 60 to move to the locked state. At this time, the fitting member 60 is disengaged from the second movable arm 51. When the second movable arm 51 is operated to move, the second movable arm 51 cannot drive the fitting member 60 to move, and thus cannot drive the first movable arm 52 to rotate through the fitting member 60, and further fails to drive the lock tongue assembly to move, making it impossible to open the door lock.
-
When the locking module 1 locks the door lock mechanism and the door lock needs to be opened, the driving assembly 70 should first be actuated to drive the fitting member 60 to move to the unlocked state. At this time, the fitting member 60 cooperates with the second movable arm 51. Then, when the second movable arm 51 is operated to move, the second movable arm 51 can drive the fitting member 60 to move, and further drive the first movable arm 52 to rotate through the fitting member 60, so that the first movable arm 52 can drive the lock tongue assembly to move to open the door lock.
-
In the extension direction of the pivot axis of the first movable arm 52, at least part of the second movable arm 51, at least part of the first movable arm 52, and at least part of the driving assembly 70 may be stacked, so as to reduce the space occupied by the first movable arm 52, the second movable arm 51, and the driving assembly 70, and facilitate the miniaturization design of the locking module 1.
-
For example, in the embodiment where the locking module 1 is applied to a vehicle, both the first movable arm 52 and the second movable arm 51 extend along the height direction of the vehicle. At least part of the first movable arm 52, the second movable arm 51, and the driving assembly 70 are stacked along the width direction or length direction of the vehicle. This makes it easy to reduce the overall space occupied by the locking module 1, so as to allow more space to be reserved for the vehicle and facilitate the layout of other components in the vehicle.
-
It will be understood here that the first movable arm 52 and the second movable arm 51 may also extend along the width direction, length direction, or other directions of the vehicle. At least part of the first movable arm 52, the second movable arm 51, and the driving assembly 70 may be stacked along the height direction or other directions of the vehicle, which is not further limited here.
-
Therefore, the locking module 1 for the door lock mechanism according to the embodiment of the present disclosure can lock the door lock mechanism to provide better safety protection for children or other special users. It has the advantages of occupying a small space and being able to allow more space to be reserved for the vehicle.
-
The following describes the locking module 1 for the door lock mechanism according to the embodiment of the present disclosure with reference to the accompanying drawings.
-
As shown in FIG. 1 to FIG. 9, the locking module 1 for the door lock mechanism according to the embodiment of the present disclosure comprises a housing 10, a first movable arm 52, a fitting member 60, a driving assembly 70, and a second movable arm 51.
-
In some embodiments of the present disclosure, as shown in FIG. 1, the rotation centers of the first movable arm 52 and the second movable arm 51 are located on the same straight line, so that when the fitting member 60 is in the unlocked state and the fitting member 60 cooperates with the second movable arm 51, operating the second movable arm 51 to rotate enables the second movable arm 51 to smoothly drive the first movable arm 52 to rotate through the fitting member 60, allowing the first movable arm 52 to drive the lock tongue assembly to move so as to open the door lock.
-
In some embodiments of the present disclosure, as shown in FIG. 3 and FIG. 7, the fitting member 60 comprises a main body 61, a rotating portion 65, and a locking portion 64. The rotating portion 65 and the locking portion 64 are spaced apart on the main body. The rotating portion 65 is rotatably arranged on the first movable arm 52. The driving assembly 70 cooperates with the locking portion 64 to drive the fitting member 60 to rotate, thereby driving the locking portion 64 to move between the unlocked state and the locked state, so that the locking portion 64 cooperates with or disengages from the second movable arm 51 to lock the door lock mechanism as required.
-
Specifically, as shown in FIG. 3 and FIG. 4, the rotating portion 65 is rotatably arranged on the first movable arm 52, and the locking portion 64 is configured to rotate around the rotation center of the rotating portion 65. When the driving assembly 70 drives the fitting member 60 to rotate to the unlocked state, the locking portion 64 rotates around the rotation center of the rotating portion 65 to a position where it cooperates with the second movable arm 51. Thus, when the second movable arm 51 is operated to rotate, the second movable arm 51 can drive the locking portion 64 to rotate around the rotation center of the second movable arm 51, thereby driving the fitting member 60 to rotate around the rotation center of the second movable arm 51. At this time, the rotating portion 65 on the fitting member 60 can drive the first movable arm 52 to rotate. As the first movable arm 52 rotates, the first movable arm 52 drives the lock tongue assembly to move to open the door lock.
-
As shown in FIG. 5 and FIG. 6, when the driving assembly 70 drives the fitting member 60 to rotate to the locked state, the locking portion 64 rotates around the rotation center of the rotating portion 65 to a position where it disengages from the second movable arm 51. At this time, when the second movable arm 51 is operated to rotate, the second movable arm 51 cannot drive the locking portion 64 to rotate, and thus cannot drive the first movable arm 52 to rotate through the rotating portion 65. At this time, the lock tongue assembly cannot be driven to move, and the door lock cannot be opened.
-
In some optional embodiments of the present disclosure, as shown in FIG. 3, the driving assembly 70 comprises a driving member 72 and a main rotating member 71. The driving member 72 is arranged on the housing 10, and the driving member 72 cooperates with the main rotating member 71 to drive the main rotating member 71 to reciprocally rotate. The main rotating member 71 cooperates with the locking portion 64. When the driving member 72 drives the main rotating member 71 to reciprocally rotate, the main rotating member 71 can drive the fitting member 60 to rotate through the locking portion 64, thereby enabling the fitting member 60 to switch between the unlocked state and the locked state, and allowing the cooperation and disengagement between the locking portion 64 and the second movable arm 51.
-
In some embodiments, as shown in FIG. 3, when the fitting member 60 is in the unlocked state and the locking portion 64 cooperates with the second movable arm 51, and it is needed to switch the fitting member 60 to the locked state, the driving member 72 drives the main rotating member 71 to rotate in the counterclockwise direction. At this time, the main rotating member 71 drives the locking portion 64 to rotate in a first direction around the rotation center of the rotating portion 65, so that the locking portion 64 rotates to a position where it is disengaged from the second movable arm 51. At this time, the fitting member 60 is switched to the locked state. When the second movable arm 51 is operated to rotate, the second movable arm 51 cannot drive the first movable arm 52 to rotate, and the first movable arm 52 cannot drive the lock tongue assembly to move.
-
In other words, as shown in FIG. 5, when the fitting member 60 is in the locked state and the locking portion 64 is disengaged from the second movable arm 51, and it is needed to switch the fitting member 60 to the unlocked state, the driving member 72 should drive the main rotating member 71 to rotate in the clockwise direction. At this time, the main rotating member 71 drives the locking portion 64 to rotate around the rotation center of the rotating portion 65 in a direction opposite to the first direction, so that the locking portion 64 rotates to a position where it cooperates with the second movable arm 51. At this time, the fitting member 60 is switched to the unlocked state. When the second movable arm 51 is operated to rotate, the second movable arm 51 can drive the fitting member 60 to rotate through the locking portion 64, and further drive the first movable arm 52 to rotate through the rotating portion 65, so that the first movable arm 52 can drive the lock tongue assembly to move to open the door lock.
-
In some optional embodiments of the present disclosure, as shown in FIG. 7, the locking module 1 further comprises a first torsion spring 81. The first torsion spring 81 is sleeved on the rotating portion 65, and both ends of the first torsion spring 81 are connected to the first movable arm 52 and the locking portion 64 respectively. The first torsion spring 81 has a driving force to drive the fitting member 60 to move toward the locked state.
-
As shown in FIG. 7, in this embodiment, the first torsion spring 81 is sleeved on the rotating portion 65, and the rotating portion 65 is rotatably arranged on the first movable arm 52. The first end of the first torsion spring 81 is connected to the first movable arm 52, and the second end of the first torsion spring 81 extends toward the locking portion 64. The locking portion 64 is provided with a limit hook 641, and the limit hook 641 and the surface of the locking portion 64 form an insertion hole 642. The second end of the first torsion spring 81 is inserted into the insertion hole 642, and the limit hook 641 can limit the position of the second end of the first torsion spring 81. The second end of the first torsion spring 81 has a driving force to drive the fitting member 60 to move toward the locked state.
-
The locking portion 64 may be in sliding contact with the main rotating member 71, so that when the driving member 72 drives the main rotating member 71 to rotate within a certain range, the main rotating member 71 is in sliding contact engagement with the locking portion 64 to overcome the driving force of the first torsion spring 81 on the locking portion 64, thereby enabling the locking portion 64 to remain in a state of cooperating with the second movable arm 51 and keeping the fitting member 60 in the unlocked state.
-
When the driving member 72 drives the main rotating member 71 to rotate to a specified position, the first torsion spring 81 can drive the locking portion 64 to rotate around the rotation center of the rotating portion 65, so that the locking portion 64 rotates to a position where it is disengaged from the second movable arm 51, enabling the fitting member 60 to switch to the locked state so as to lock the door lock mechanism.
-
In some specific embodiments of the present disclosure, as shown in FIG. 9, the main rotating member 71 is arranged with a guide protrusion 710, and the outer peripheral wall of the guide protrusion 710 is arranged with an arc-shaped guide surface 711. The locking portion 64 is in abutting engagement with the guide surface 711. When the locking portion 64 abuts against the guide surface 711, the guide surface 711 exerts a force on the locking portion 64, enabling the locking portion 64 to overcome the driving force of the first torsion spring 81. Further, during the abutting engagement between the guide surface 711 and the locking portion 64, the locking portion 64 can remain in a position cooperating with the second movable arm 51, thereby maintaining the fitting member 60 in the unlocked state.
-
When the locking portion 64 disengages from the guide surface 711, the guide surface 711 no longer exerts a force on the locking portion 64. At this time, the first torsion spring 81 drives the locking portion 64 to rotate to a position where it is disengaged from the second movable arm 51, thereby enabling the fitting member 60 to switch to the locked state. At this time, when the second movable arm 51 is operated to rotate, the second movable arm 51 cannot drive the locking portion 64 to rotate, and further cannot drive the first movable arm 52 to rotate through the fitting member 60. The first movable arm 52 cannot drive the lock tongue assembly to move, and the lock cannot be opened at this time.
-
When the driving member 72 drives the main rotating member 71 to rotate, the locking portion 64 is in sliding engagement with the guide surface 711, the guide surface 711 is arc-shaped so that when the locking portion 64 slides relative to the guide surface 711, the distance between the locking portion 64 and the center of the main rotating member 71 remains unchanged, so that the locking portion 64 may be maintained in a position cooperating with the second movable arm 51.
-
In some embodiments, as shown in FIG. 9, the guide protrusion 710 further comprises a guiding surface 712. One end of the guiding surface 712 is connected to the guide surface 711, and the other end of the guiding surface 712 extends toward the inside of the main rotating member 71. The driving member 72 can drive the main rotating member 71 to rotate between a first position and a second position. When the main rotating member 71 is in the first position or rotating between the first position and the second position, the locking portion 64 is in abutting engagement with the guide surface 711. At this time, the guide surface 711 exerts a force on the locking portion 64 to overcome the first torsion spring 81, so that the locking portion 64 can be maintained in a position cooperating with the second movable arm 51, thereby maintaining the fitting member 60 in the unlocked state.
-
When the main rotating member 71 rotates between the first position and the second position, the locking portion 64 slides relative to the guide surface 711 to one end where the guide surface 711 is connected to the guiding surface 712. When the main rotating member 71 rotates to the second position, the locking portion 64 disengages from the guide surface 711. At this time, the first torsion spring 81 can drive the locking portion 64 to rotate counterclockwise toward the inside of the main rotating member 71, so that the locking portion 64 rotates to a position where it is disengaged from the second movable arm 51. At this time, the guiding surface 712 is in contact engagement with the locking portion 64 to limit the range of rotation of the locking portion 64 driven by the first torsion spring 81.
-
When the main rotating member 71 rotates from the second position to the first position, the locking portion 64 can slide relative to the guiding surface 712. At this time, the guiding surface 712 exerts a force on the locking portion 64, enabling the locking portion 64 to overcome the driving force of the first torsion spring 81, so that the locking portion 64 can rotate toward the outside of the main rotating member 71 along the guiding surface 712. When the locking portion 64 slides along the guiding surface 712 to the guide surface 711, the locking portion 64 cooperates with the second movable arm 51, and the fitting member 60 switches to the unlocked state at this time.
-
It will be understood that the terms "inside" and "outside" mentioned herein are relative to the center of the main rotating member 71: the position close to the center of the main rotating member 71 is "inside", and the position far from the center of the main rotating member 71 is "outside".
-
In some specific embodiments of the present disclosure, as shown in FIG. 1, the driving member 72 is in meshing engagement with the main rotating member 71, so that the driving member 72 can drive the main rotating member 71 to reciprocally rotate, thereby driving the locking portion 64 to move. This enables the locking portion 64 to engage with or disengage from the second movable arm 51, allowing the fitting member 60 to switch between the unlocked state and the locked state, and thus selectively locking the door lock mechanism as required.
-
Wherein, the driving member 72 is configured to control the rotation direction of the main rotating member 71, so as to enable clockwise or counterclockwise rotation of the main rotating member 71. This further controls the locking portion 64 to engage with or disengage from the second movable arm 51, and allows the fitting member 60 to switch between the unlocked state and the locked state, thereby selectively locking the door lock mechanism as required.
-
For example, when the driving member 72 drives the main rotating member 71 to rotate counterclockwise, the main rotating member 71 gradually rotates from the first position to the second position. At this time, the locking portion 64 rotates from a position engaging with the second movable arm 51 to a position disengaging from the second movable arm 51, and the fitting member 60 switches from the unlocked state to the locked state.
-
When the driving member 72 drives the main rotating member 71 to rotate clockwise, the main rotating member 71 gradually rotates from the second position to the first position. At this time, the locking portion 64 rotates from a position disengaging from the second movable arm 51 to a position engaging with the second movable arm 51, and the fitting member 60 switches from the locked state to the unlocked state.
-
In some embodiments, as shown in FIG. 1, the driving member 72 comprises a driving motor 722 and a worm 721. The driving motor 722 cooperates with the worm 721 to drive the worm 721 to rotate, and the worm 721 is in meshing engagement with the main rotating member 71. When the driving motor 722 drives the worm 721 to rotate, the worm 721 can drive the main rotating member 71 to rotate, thereby realizing the reciprocal rotation of the main rotating member 71.
-
Wherein, the driving motor 722 drives the main rotating member 71 to rotate through the worm 721, which facilitates the reasonable arrangement of the positions of the driving motor 722, the worm 721 and the main rotating member 71, and reduces the space occupied by the driving assembly 70.
-
As shown in FIG. 1, by arranging the worm 721, the rotation of the driving motor 722 is transmitted to the main rotating member 71 through the worm 721, so that the length direction of the driving motor 722 can be consistent with the length direction of the main rotating member 71, the first movable arm 52, or the second movable arm 51. This makes it easy to reduce the space occupied by the driving motor 722 in other planes, facilitates the reasonable arrangement of the driving assembly 70, and reduces the space occupied by the driving assembly 70.
-
In some examples, as shown in FIG. 2, the locking module 1 further comprises a second torsion spring 82. The second torsion spring 82 is respectively connected to the housing 10 and the main rotating member 71. When the main rotating member 71 rotates, the second torsion spring 82 provides assistance for the fitting member 60 to switch to the unlocked state, so that when the driving member 72 drives the main rotating member 71 to rotate and the fitting member 60 switches to the unlocked state, the main rotating member 71 can be smoothly rotated to the specified position, and the fitting member 60 can be smoothly switched to the unlocked state.

In some optional embodiments of the present disclosure, as shown in FIG. 3, FIG. 7, and FIG. 8, the locking portion 64 is a locking protrusion protruding from the main body 61. The second movable arm 51 is provided with a locking slot 511. When the locking portion 64 is in the unlocked state, the locking protrusion cooperates with the inner wall of the locking slot 511, so that when the second movable arm 51 is operated to rotate, the second movable arm 51 can drive the locking protrusion in the locking slot 511 to rotate, and further drive the first movable arm 52 to rotate through the fitting member 60, so that the first movable arm 52 can drive the lock tongue assembly to move to open the door lock.
-
As shown in FIG. 5, when the locking portion 64 is in the locked state, the locking protrusion is disengaged from the inner wall of the locking slot 511, and at this time, the locking protrusion is spaced from the inner wall of the locking slot 511. When the second movable arm 51 is operated to rotate, the second movable arm 51 cannot drive the locking protrusion to rotate, and thus cannot drive the first movable arm 52 to rotate. At this time, the lock tongue assembly will not move, and the door lock cannot be opened.
-
In some embodiments, as shown in FIG. 7, the second movable arm 51 is provided with a clearance slot 512. One end of the clearance slot 512 communicates with the locking slot 511. When the locking portion 64 is in the locked state, the locking portion 64 is located within the clearance slot 512. At this time, when the second movable arm 51 is operated to rotate, the clearance slot 512 avoids the locking portion 64, and the second movable arm 51 cannot drive the locking portion 64 to rotate.
-
In other embodiments, the second movable arm 51 is arranged with a clearance protrusion that protrudes away from the locking protrusion, so that when the locking portion 64 is in the locked state, the locking portion 64 is positioned corresponding to the clearance protrusion. At this time, when the second movable arm 51 is operated to rotate, the clearance protrusion avoids the locking portion 64, and the second movable arm 51 cannot drive the locking portion 64 to rotate.
-
In some embodiments of the present disclosure, as shown in FIG. 1, the locking module 1 further comprises a cable mechanism 90. One end of the cable mechanism 90 is connected to one end of the second movable arm 51. Pulling the cable mechanism 90 can drive the second movable arm 51 to rotate. When the fitting member 60 is in the unlocked state, the second movable arm 51 can drive the fitting member 60 to rotate, which in turn drives the first movable arm 52 to rotate through the fitting member 60, enabling the first movable arm 52 to drive the lock tongue assembly to move and open the door lock.
-
As shown in FIG. 1, in the embodiment, the cable mechanism 90 comprises a handle 91 and a cable pull portion 92. One end of the cable pull portion 92 is connected to the handle 91, and the other end of the cable pull portion 92 is connected to the second movable arm 51. The connection point of the second movable arm 51 to the cable pull portion 92 is at a certain distance from the rotation center of the second movable arm 51. An operator can operate the handle 91 to move the cable portion 92 along its extension direction, thereby pulling the second movable arm 51 to rotate.
