DETAILED DESCRIPTION
-
The embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, but should not be construed as limiting the present disclosure.
-
The central control mechanism 1 of the door lock assembly according to an embodiment of the present disclosure is described below with reference to the accompanying drawings.
-
As shown in FIG. 1 to FIG. 10, the central control mechanism 1 for the door lock assembly according to an embodiment of the present disclosure includes a housing 10, a locking linkage 41, an opening assembly 30 and a driving assembly 42.
-
The locking linkage 41 is rotatably arranged on the housing 10, and the locking linkage 41 is arranged with a first engagement portion. The opening assembly 30 is movably arranged in the housing 10, and the opening assembly 30 can switch between an engaged state and a disengaged state. When the opening assembly 30 is in the engaged state, the opening assembly 30 is adapted to engage with the bolt assembly 20. For example, when the opening assembly 30 moves, it can drive the bolt assembly 20 to rotate to open the door lock. When the opening assembly 30 is in the disengaged state, the opening assembly 30 is adapted to disengage from the bolt assembly 20, and at this time, the opening assembly 30 cannot drive the bolt assembly 20 to move, so that the door lock cannot be opened by moving the opening assembly 30.
-
The opening assembly 30 is arranged with a second engagement portion, and the driving assembly 42 is arranged on the housing 10. The driving assembly 42 engages with the locking linkage 41 to drive the locking linkage 41 to reciprocate. Further, when the locking linkage 41 reciprocates and drives the first engagement portion to rotate, the first engagement portion and the second engagement portion can be engaged or disengaged.
-
When the first engagement portion is engaged with the second engagement portion and the driving assembly 42 drives the locking linkage 41 to rotate, the locking linkage 41 can push the opening assembly 30 to switch between the engaged state and the disengaged state.
-
Specifically, when the first engagement portion is engaged with the second engagement portion, the driving assembly 42 can drive the locking linkage to rotate, and the locking linkage drives the opening assembly 30 to move through the first engagement portion and the second engagement portion, so that the opening assembly 30 switches between the engaged state and the disengaged state.
-
When the opening assembly 30 is in the engaged state, operating the opening assembly 30 to move at this time enables the opening assembly 30 to drive the bolt assembly 20 to rotate, thereby opening the door lock, and the door lock can be opened normally at this time. When the opening assembly 30 is in the disengaged state, operating the opening assembly 30 to move at this time will not enable the opening assembly 30 to drive the bolt assembly 20 to move. At this time, the door lock can be secured to prevent the door lock from being opened when the opening assembly 30 is accidentally touched, thereby providing better safety protection for children or other special users.
-
In other words, the driving assembly 42 directly drives the locking linkage 41 to rotate, and uses the locking linkage 41 to directly control the opening assembly 30 to switch between the engaged state and the disengaged state. Such an arrangement allows the switching of the opening assembly 30 between the engaged state and the disengaged state without excessive transmission mechanisms, which is convenient for simplifying the structure and improving the stability of transmission.
-
Therefore, the central control mechanism 1 of the door lock assembly according to an embodiment of the present disclosure can secure the door lock to provide better safety protection for children or other special users, and has the advantages of simple structure, stable transmission, etc.
-
The central control mechanism 1 of the door lock assembly according to specific embodiments of the present disclosure is described below with reference to the accompanying drawings.
-
As shown in FIG. 1 to FIG. 10, the central control mechanism 1 for the door lock assembly according to an embodiment of the present disclosure includes a housing 10, a locking linkage 41, an opening assembly 30 and a driving assembly 42.
-
In some embodiments of the present disclosure, as shown in FIG. 4, the central control mechanism 1 further includes an elastic member 82, which is respectively connected to the locking linkage 41 and the housing 10. When the opening assembly 30 is switched to the engaged state or the disengaged state, the elastic member 82 positions the locking linkage 41 at the current position, so that when the locking linkage 41 drives the opening assembly 30 to move, the opening assembly 30 can be positioned in the engaged state or the disengaged state, preventing the opening assembly 30 from moving when subjected to unintended force, which affects the state of the opening assembly 30.
-
In some embodiments, the driving assembly 42 can drive the locking linkage 41 to rotate between a first position and a second position. When the locking linkage 41 rotates to the first position, the opening assembly 30 is switched to the engaged state; when the locking linkage 41 rotates to the second position, the opening assembly 30 is switched to the disengaged state. The elastic member 82 can position the locking linkage 41 at the first position or the second position, thereby positioning the opening assembly 30 in the engaged state or the disengaged state.
-
As shown in FIG. 4, in the embodiment, when the first engagement portion is engaged with the second engagement portion and the driving assembly 42 drives the locking linkage 41 to rotate counterclockwise, the locking linkage 41 gradually rotates from the first position to the second position. When the locking linkage 41 rotates to a specified position close to the second position, the elastic member exerts a driving force on the locking linkage 41 to approach the second position, so that the locking linkage 41 can smoothly rotate to the second position and be positioned there, thereby positioning the opening assembly 30 in the disengaged state.
-
When the driving assembly 42 drives the locking linkage 41 to rotate clockwise, the locking linkage 41 gradually rotates from the second position to the first position. When the locking linkage 41 rotates to a specified position close to the first position, the elastic member exerts a driving force on the locking linkage 41 to approach the first position, so that the locking linkage 41 can smoothly rotate to the first position and be positioned there, thereby positioning the opening assembly 30 in the engaged state.
-
In some embodiments, the elastic member 82 includes a linkage spring 821, one end of which is connected to the locking linkage 41 and the other end is connected to the housing 10, so that the linkage spring 821 is connected between the locking linkage 41 and the housing 10, and the housing 10, the linkage spring 821 and the locking linkage 41 can be distributed in sequence. The linkage spring 821 is arranged such that its elastic potential energy is maximum when the locking linkage 41 rotates between the first position and the second position, and minimum when the locking linkage 41 rotates to the first position or the second position, so that the linkage spring 821 can position the locking linkage 41 at the first position or the second position, ensuring that the opening assembly 30 can be in the engaged state or the disengaged state, and preventing the central control mechanism 1 from malfunctioning.
-
In some embodiments, the elastic member 82 further includes a buffer block 822. The locking linkage 41 has a clearance groove 419. The buffer block 822 is connected to the housing 10 and located in the clearance groove 419. When the locking linkage 41 rotates, the side wall of the clearance groove 419 is adapted to contact the buffer block 822 to limit the rotation range of the locking linkage 41.
-
The buffer block 822 is made of elastic materials such as rubber, and is connected to the side of the housing 10 facing the locking linkage 41. The buffer block 822 is arranged opposite to the clearance groove 419 so as to extend into the clearance groove 419. During the process that the locking linkage 41 drives the opening assembly 30 to switch to the engaged state or the disengaged state, the buffer block 822 can abut against the side wall of the clearance groove 419 to achieve buffer energy absorption, making the movement of the locking linkage 41 and the opening assembly 30 smooth and reliable. Moreover, the buffer block 822 can be used to limit the locking linkage 41, thereby limiting the rotation range of the locking linkage 41. Therefore, it is conducive to improving the movement stability of the locking linkage 41 and the reliability of the central control mechanism 1.
-
In some embodiments of the present disclosure, as shown in FIG. 4, the first engagement portion is a notch 413 arranged on the locking linkage 41, and the second engagement portion is a boss 311 extending into the notch 413. The boss 311 extends into the notch 413. When the driving assembly 42 drives the locking linkage 41 to rotate, the inner wall of the notch 413 abuts against the boss 311, so as to drive the opening assembly 30 to switch between the engaged state and the disengaged state through the boss 311.
-
As shown in FIG. 1, FIG. 2, FIG. 6, and FIG. 7, in the embodiment, when the driving assembly 42 drives the locking linkage 41 to rotate clockwise, and the locking linkage 41 rotates from the second position to the first position, the notch 413 rotates in a direction away from the boss 311. When the first engagement portion is about to disengage from or has disengaged from the second engagement portion, the opening assembly 30 is in the engaged state.
-
When the driving assembly 42 drives the locking linkage 41 to rotate counterclockwise, and the locking linkage 41 rotates from the first position to the second position, the notch 413 moves in a direction close to the boss 311. At this time, the first engagement portion is engaged with the second engagement portion. When the driving assembly 42 continues to drive the locking linkage 41 to rotate counterclockwise, the inner wall of the notch 413 abuts against the boss 311 and drives the boss 311 to move, so as to drive the opening assembly 30 to move through the boss 311, making the opening assembly 30 switch to the disengaged state.
-
In some embodiments, as shown in FIG. 4, the central control mechanism 1 further has a first reset member 841, which is arranged on the opening assembly 30 and the housing 10. The first reset member 841 has a driving force for driving the opening assembly 30 to switch to the engaged state. When the driving assembly 42 drives the locking linkage 41 to rotate clockwise, and the locking linkage 41 rotates from the second position to the first position, the first reset member 841 can drive the opening assembly 30 to switch to the engaged state, so that the opening assembly 30 can smoothly switch to the engaged state to unlock the door lock's security.
-
In some embodiments of the present disclosure, as shown in FIG. 6 to FIG 8, a hook 312 is arranged on the side of the opening assembly 30 away from the boss 311. When the opening assembly 30 is in the engaged state, the hook 312 is engaged with the bolt assembly 20, and at this time, the opening assembly 30 can drive the bolt assembly 20 to rotate, thereby opening the door lock. When the opening assembly 30 is in the disengaged state, the hook 312 is disengaged from the bolt assembly 20, and at this time, the opening assembly 30 cannot drive the bolt assembly 20 to move, so the door lock cannot be opened by moving the opening assembly 30.
-
In some specific embodiments of the present disclosure, the locking linkage 41 is configured such that when rotating toward a position where it can push the opening assembly 30 to rotate, the boss 311 is in sliding fit with one of the side walls of the notch 413 to slide toward the corner of the notch 413, so that the notch 413 and the boss 311 can maintain engagement, thereby limiting the position of the boss 311. Further, when the locking linkage 41 rotates, the locking linkage 41 can drive the opening assembly 30 to rotate through the boss 311, preventing the boss 311 from sliding to other positions along the inner wall of the notch 413 when the opening assembly 30 switches between the engaged state and the disengaged state, which affects the engagement between the boss 311 and the notch 413.
-
In some embodiments, the boss 311 is formed as a cylinder, so that when the boss 311 is engaged with the notch 413 and the inner wall of the notch 413 pushes the boss 311 to rotate, the friction between the boss 311 and the inner wall of the notch 413 can be reduced, so that the locking linkage 41 can smoothly drive the boss 311 to rotate, enabling the opening assembly 30 to smoothly switch between the engaged state and the disengaged state.
-
In some embodiments of the present disclosure, as shown in FIG. 3, the driving assembly 42 includes a first motor 421 and a driving gear 422. The first motor 421 engages with the driving gear 422 to drive it to rotate, and the driving gear 422 meshes with the locking linkage 41. When the first motor 421 drives the driving gear 422 to rotate, the driving gear 422 can drive the locking linkage 41 to rotate, so that the locking linkage 41 can push the opening assembly 30 to switch between the engaged state and the disengaged state, so as to secure or unsecure the door lock as needed.
-
By controlling the rotation direction of the output shaft of the first motor 421, the rotation direction of the driving gear 422 can be controlled, thereby controlling the rotation direction of the locking linkage 41, so that the locking linkage 41 can push the opening assembly 30 to switch between the engaged state and the disengaged state, and further secure or unsecure the door lock as needed.
-
In some embodiments of the present disclosure, as shown in FIG. 1 to FIG. 4, the driving assembly 42 includes a first transmission arm 51, which is rotatably arranged on the housing 10. The locking linkage 41 has a guide portion 414, and the first end of the first transmission arm 51 is in abutting fit with the guide portion 414. When the first transmission arm 51 rotates, it can drive the locking linkage 41 to rotate, and further, when the first engagement portion is engaged with the second engagement portion, the first transmission arm 51 can drive the opening assembly 30 to switch between the engaged state and the disengaged state.
-
In some specific embodiments of the present disclosure, the guide portion 414 includes a guide slope and/or a guide arc surface, and the first transmission arm 51 is arranged with an arc surface 511 in sliding contact with the guide portion 414. When the first transmission arm 51 is operated to rotate, the arc surface 511 abuts against the guide slope and/or the guide arc surface, so as to drive the locking linkage 41 to rotate through the guide slope and/or the guide arc surface.
-
As shown in FIG. 4, in the embodiment, the guide portion 414 has a guide slope, which extends toward the direction close to the arc surface 511. When the first transmission arm 51 rotates clockwise, the arc surface 511 exerts a pushing force on the guide slope to push the locking linkage 41 to rotate clockwise, so that the locking linkage 41 rotates from the second position to the first position, and at this time, the locking linkage 41 can drive the opening assembly 30 to switch from the disengaged state to the engaged state.
-
In some embodiments, the main control mechanism for the door lock assembly further has a second reset member, which is arranged on the locking linkage 41 and the housing 10, and has a driving force for driving the locking linkage 41 to rotate toward the second position. So that when the first transmission arm 51 is released and the arc surface 511 no longer exerts a pushing force on the guide slope and/or the guide arc surface, the locking linkage 41 can automatically rotate from the first position to the second position under the drive of the second reset member, and at the same time, the locking linkage 41 can drive the opening assembly 30 to switch from the engaged state to the disengaged state.
-
In some specific embodiments of the present disclosure, as shown in FIG. 1, the central control mechanism 1 further includes a cable device 90. One end of the cable device 90 is connected to the second end of the first transmission arm 51. Pulling the cable device 90 can drive the first transmission arm 51 to rotate, and further drive the locking linkage 41 to rotate through the first transmission arm 51. Thus, when the first engagement portion is engaged with the second engagement portion, the first transmission member can drive the locking linkage 41 to rotate, enabling the locking linkage 41 to drive the opening assembly 30 to switch between the engaged state and the disengaged state, so as to secure or unsecure the door lock as needed.
-
As shown in FIG. 1, in some embodiments, the cable device 90 includes a handle 91 and a cable portion 92. One end of the cable portion 92 is connected to the handle 91, and the other end is connected to the first transmission arm 51. The connection position of the first transmission arm 51 and the cable portion 92 is at a certain distance from the rotation center of the first transmission arm 51. An operator can operate the cable portion 92 to move along its extending direction through the handle 91, thereby pulling the first transmission arm 51 to rotate.
-
To sum up, the driving assembly 42 can drive the locking linkage 41 to rotate in two ways. One way is that the first motor 421 drives the driving gear 422 to rotate, and the driving gear 422 can drive the locking linkage 41 to rotate, enabling the locking linkage 41 to drive the opening assembly 30 to rotate, so that the opening assembly 30 can switch between the engaged state and the disengaged state.
-
The other way is that the handle 91 drives the first transmission arm 51 to rotate, and the first transmission arm 51 can drive the locking linkage 41 to rotate, enabling the locking linkage 41 to drive the opening assembly 30 to rotate, so that the opening assembly 30 can switch between the engaged state and the disengaged state. When controlling the opening assembly 30 to be in the engaged state or the disengaged state, only one of these two ways is needed.
-
In some embodiments of the present disclosure, as shown in FIG. 4, the locking linkage 41 includes a first extending portion 411 and a second extending portion 412 with an included angle. The first extending portion 411 is arranged with the first engagement portion, and the driving assembly 42 is engaged with the second extending portion 412. When the driving assembly 42 drives the locking linkage 41 to rotate through the second extending portion 412, through the engagement between the first engagement portion and the second engagement portion, the first extending portion 411 can drive the opening assembly 30 to switch between the engaged state and the disengaged state.
-
As shown in FIG. 2, in the embodiment, the housing 10 includes a first side wall 11 and a second side wall 12. The first side wall 11 extends in the horizontal direction, and the second side wall 12 extends in the vertical direction. The opening assembly 30 is arranged on the first side wall 11, and the driving assembly 42 is arranged on the second side wall 12. The included angle between the first extending portion 411 and the second extending portion 412 is 90 degrees. The first extending portion 411 extends in the horizontal direction, so that it can smoothly engage with the opening assembly 30 on the first side wall 11, enabling the locking linkage 41 to drive the opening assembly 30 to switch between the engaged state and the disengaged state when rotating. The second extending portion 412 extends in the vertical direction, so that it can smoothly engage with the driving assembly 42 on the second side wall 12, enabling the driving assembly 42 to smoothly drive the locking linkage 41 to rotate through the first extending portion 411.
-
In addition, by engaging the first extending portion 411 with the opening assembly 30 and the second extending portion 412 with the driving assembly 42, it adapts to the arrangement positions of the opening assembly 30 and the driving assembly 42 on the housing 10, which is conducive to reducing the volume occupied by the locking linkage 41, the driving assembly 42 and the opening assembly 30 in the housing 10, and facilitating the miniaturized design of the door lock assembly.
-
In some embodiments of the present disclosure, as shown in FIG. 5 to FIG. 7, the central control mechanism 1 further includes a detection device 83, which is used to detect the current position of the locking linkage 41. It should be noted that the detection device 83 can be electrically connected to the control center of the vehicle, so that the detection device 83 can transmit the detection result to the control center of the vehicle.
-
With the above arrangement, the detection device 83 can detect the current position of the locking linkage 41, so that the control center can determine whether the opening assembly 30 is in the engaged state or the disengaged state, and thus determine whether the door is secured. The control center can display the detection result through a display device to prompt the driver, which is conducive to improving driving safety.
-
In some embodiments of the present disclosure, as shown in FIG. 7, the detection device 83 is a microswitch, which is mounted on the housing 10. The locking linkage 41 is arranged with a first detection surface 416 and a second detection surface 417, and the heights of the first detection surface 416 and the second detection surface 417 are different. When the opening assembly 30 is switched to the engaged state, the first detection surface 416 is in contact with the microswitch to make the microswitch send information; when the opening assembly 30 is switched to the disengaged state, the second detection surface 417 is directly opposite to the microswitch.
-
As shown in FIG. 3, in the embodiment, the microswitch is mounted on the housing 10 and is arranged above the locking linkage 41. The upper side wall of the locking linkage 41 corresponds to the microswitch, and the upper side wall of the locking linkage 41 is arranged with the first detection surface 416 and the second detection surface 417 with different heights. For example, the height of the first detection surface 416 can be set to be greater than that of the second detection surface 417. The lower end of the microswitch is arranged with a contact head 831, which is used to contact the first detection surface 416 or the second detection surface 417.
-
Specifically, when the locking linkage 41 rotates to drive the opening assembly 30 to switch to the engaged state, the first detection surface 416 is directly opposite to the microswitch, and the contact head 831 can be in contact with the first detection surface 416. At this time, the microswitch is triggered to continuously send information to the control center, and it can be determined that the door lock is no longer secured. When the locking linkage 41 drives the opening assembly 30 to switch to the disengaged state, the second detection surface 417 is directly opposite to the microswitch, and the contact head 831 is opposite to the second detection surface 417 without contact (of course, contact is also possible, which is not limited in the present disclosure). At this time, the microswitch is not triggered and does not send information to the control center, and it can be determined that the door is secured. With the above arrangement, the detection accuracy of the microswitch can be improved, and the reliability of the central control mechanism 1 can be enhanced.

In some embodiments of the present disclosure, the first detection surface 416 is connected to the second detection surface 417 through a connecting slope 418, and the included angle between the connecting slope 418 and the horizontal plane is set as 'a', which satisfies: 40°≤a≤60°.
-
For example, as shown in FIG. 4, the first detection surface 416 and the second detection surface 417 can be connected through the connecting slope 418, so that the contact head 831 can stably switch between the first detection surface 416 and the second detection surface 417, which can reduce the impact on the contact head 831 during movement and improve the service life of the microswitch.
-
Furthermore, the included angle a between the connecting slope 418 and the horizontal plane can be set to satisfy: 40°≤a≤60°. In other words, the included angle a between the connecting slope 418 and the horizontal plane can be 45°, 50° or 55°, which is not limited in the present disclosure. Therefore, not only the movement smoothness of the contact head 831 can be ensured, but also the situation that the height difference between the first detection surface 416 and the second detection surface 417 is too small can be avoided, the possibility of misjudgment is reduced, and the reliability of the central control mechanism 1 is improved.

The door lock assembly according to an embodiment of the present disclosure is described below. The door lock assembly according to an embodiment of the present disclosure includes a bolt assembly 20 and the central control mechanism 1 of the door lock assembly according to the above embodiment of the present disclosure.
-
The bolt assembly 20 is rotatably arranged on the housing 10, and when the opening assembly 30 drives the bolt assembly 20 to rotate, the door can be opened.
-
The door lock assembly according to an embodiment of the present disclosure can secure the door lock by using the central control mechanism 1 of the door lock assembly according to the above embodiment of the present disclosure, so as to provide better safety protection for children or other special users, and has the advantages of simple structure, stable transmission, etc.
-
The vehicle according to an embodiment of the present disclosure is described below. The vehicle according to an embodiment of the present disclosure includes a door and the door lock assembly according to the above embodiment of the present disclosure.
-
The housing 10 is arranged on the door, and the vehicle body is arranged with a bolt engaging portion engaged with the bolt assembly 20. When the bolt assembly 20 moves, the bolt assembly 20 is disengaged from the bolt engaging portion to open the door.
-
As shown in FIG. 9 and FIG. 10, in the embodiment, the bolt assembly 20 includes a locking member 22 and an engaging member 21, which are spaced apart. Both the engaging member 21 and the locking member 22 are arranged to be rotatable relative to the housing 10, and the engaging member 21 is used to selectively limit the locking member 22, so that the locking member 22 can be engaged with or disengaged from the bolt engaging portion of the vehicle body. Specifically, when the engaging member 21 rotates to the position shown in FIG. 9, the engaging member 21 can limit the locking member 22, so that the locking member 22 can be engaged with the bolt engaging portion of the vehicle body to lock the door; when the engaging member 21 rotates to the position shown in FIG. 10, the engaging member 21 can avoid the locking member 22, and the locking member 22 can rotate and be disengaged from the bolt engaging portion of the vehicle body to open the door.
-
Specifically, when there is no need to secure the door, the locking linkage 41 can drive the opening assembly 30 to switch to the engaged state, and at this time, the opening assembly 30 can be engaged with the bolt assembly 20, that is, the opening assembly 30 is engaged with the engaging member 21. At this time, if an external force is applied to the opening assembly 30 (for example, by a motor or a handle), the opening assembly 30 can drive the engaging member 21 to move, so that the engaging member 21 avoids the locking member 22, enabling the locking member 22 to rotate and be disengaged from the bolt engaging portion of the vehicle body to open the door.
-
When it is necessary to secure the door, the locking linkage 41 can drive the opening assembly 30 to switch to the disengaged state, and the opening assembly 30 is separated from the bolt assembly 20, that is, the opening assembly 30 is separated from the engaging member 21. At this time, if an external force is applied to the opening assembly 30, the opening assembly 30 cannot drive the engaging member 21 to move, and the door remains locked. Therefore, the security of the door is achieved.
-
The vehicle according to an embodiment of the present disclosure can secure the door by using the door lock assembly according to the above embodiment of the present disclosure, so as to provide better safety protection for children or other special users, and has the advantages of simple structure, stable transmission, etc.
