Description

Technical Field

[0001] The present invention belongs to the technical field of automotive parts, and particularly relates to an automotive door lock actuator mechanism with self - suction and interruption functions. Background Art

[0002] Automotive door locks are an important part of the vehicle body, mainly responsible for controlling the opening, closing, and locking of the doors.

[0003] Traditional automotive door locks generally use mechanical locking mechanisms. However, with the increasing demand of consumers for the intelligence, convenience, and safety of automotive door lock systems, electric door lock systems have gradually become the mainstream. Electric door lock systems generally use motors to drive the locking tongues and achieve door lock locking and unlocking by controlling the on - off of the motors. However, in actual use, there are also some problems with electric door lock systems.

[0004] For example, during the self - suction locking process, if the motor fails or jams, or the door system anti - pinch function fails, the self - suction process needs to be stopped in a timely manner. However, the existing self - suction structures of door locks are complex, requiring additional unlocking tools or arranging separate emergency unlocking mechanisms and cables on the lock body, resulting in problems such as high cost, poor weight reduction effect, and troublesome assembly and operation of the door lock system. In addition, after the self - suction is interrupted in some door locks, the locking tongue is blocked by the interruption mechanism and cannot be reset, so that the door lock system cannot be closed, which may pose potential safety hazards during the maintenance process.

[0005] The Chinese patent application with the publication number CN113175280A discloses an automotive door lock with a self - suction function. The self - suction interruption mechanism of this door lock is through the cooperation of a safety lever, a release arm, and a clutch arm. When in use, the release arm is driven to rotate by the outer opening arm or the inner opening arm. The release arm drives the safety lever to rotate, and the first stop column of the safety lever pushes aside the self - suction rod to interrupt the self - suction function. At the same time, the release arm drives the stop claw to rotate through the cooperation of the first protrusion and the second protrusion, so that the stop claw disengages from the second engaging part to open the door lock. Although the above - mentioned automotive door lock can interrupt the self - suction locking process, its structure is complex and it is difficult to reduce the production cost. Summary of the Invention

[0006] The purpose of the present invention is to provide an automotive door lock actuator mechanism with self - suction and interruption functions and a simple structure to solve the problems raised in the above background art.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0031] Embodiment 1:

[0032] As Figures 1 - 3 shown, this embodiment provides an automotive door lock actuator mechanism with self - suction and interruption, including:

[0033] An unlocking lever 100, rotatably arranged;

[0034] A first locking lever 200, rotatably arranged;

[0035] A self - suction assembly for automatically controlling the rotation of the unlocking lever 100 and for automatically controlling the rotation of the first locking lever 200;

[0036] And an interruption assembly for manually controlling the rotation of the unlocking lever 100 and the first locking lever 200, and at the same time being able to control the interruption of the self - suction assembly's rotation of the first locking lever 200.

[0037] In this technical solution, for the automotive door lock system, the unlocking lever 100 is used to open the door lock, and the first locking lever 200 is used to close the door lock. To achieve automatic control of the opening or closing of the door lock, a self - suction assembly is provided. The self - suction assembly automatically controls the rotation of the unlocking lever 100 to achieve the opening of the door lock, and automatically controls the rotation of the first locking lever 200 to achieve the closing of the door lock.

[0038] Among them, for some special situations, such as when the self - suction assembly fails or when a finger is pinched in the case of the tailgate strut anti - pinch failure or other situations where the self - suction process needs to be interrupted, an interruption assembly is required to unlock the door lock. Therefore, an interruption assembly is also provided. The interruption assembly can be manually controlled when necessary to meet the usage requirements of the door lock in special situations.

[0039] Specifically, a first card slot 210 is provided on the first locking lever 200; the interruption assembly includes:

[0040] The movable column 410 is movably arranged on the first card slot 210 along the length direction of the first card slot 210;

[0041] The second locking lever 420 is rotatably arranged. A second card slot 421 facing the first card slot 210 and a third card slot 422 communicating with the second card slot 421 are formed on the second locking lever 420. The movable column 410 also extends into the second card slot 421;

[0042] Wherein, when the extended end of the movable column 410 is located in the second card slot 421 and the second locking lever 420 rotates, the second locking lever 420 drives the movable column 410 and the first locking lever 200 to rotate;

[0043] When the movable column 410 moves so that its extended end moves from the second card slot 421 to the third card slot 422, and when the second locking lever 420 rotates, the movable column 410 and the first locking lever 200 remain stationary.

[0044] The interruption component further includes:

[0045] The manual release lever 430 is rotatably arranged and has two driving ends and one stress end;

[0046] Wherein, when the manual release lever 430 rotates, one driving end of the manual release lever 430 is used to drive the unlocking lever 100 to rotate, and at the same time, the other driving end of the manual release lever 430 is used to drive the movable column 410 to move so that it moves from the second card slot 421 into the third card slot 422. When the movable column 410 slides in the third card slot 422, it drives the first locking lever 200 to rotate at the same time.

[0047] In this technical solution, the first card slot 210 formed on the first locking lever 200, the second card slot 421 formed on the second locking lever 420 facing the first card slot 210, and the third card slot 422 communicating with the second card slot 421, and the movable column 410 extending into the second card slot 421. These structures enable the movable column 410, the first locking lever 200 and the second locking lever 420 to cooperate with each other to realize the automatic and manual control of the door lock system.

[0048] During the automatic control process, the self - suction component applies an external force to the second locking lever 420 and makes it rotate. The second locking lever 420 then drives the movable column 410 and the first locking lever 200 to rotate, and then the first locking lever 200 rotates, and finally closes the door lock.

[0049] The self - suction component applies an external force to the unlocking lever 100 and makes it rotate, so as to realize unlocking the door lock.

[0050] For the structural setting of the interruption component, an important design point is the second locking lever 420. By opening a second card slot 421 and a third card slot 422 on the second locking lever 420, the third card slot 422 is set as an arc slot, and the center of the arc slot is located on the rotation axis of the second locking lever 420. The first locking lever 200 is rotatably arranged coaxially with the second locking lever 420. The external force applied by the manual release lever 430 to the movable column 410 will cause the movable column 410 to move downward by a certain displacement, that is, from the second card slot 421 to the third card slot 422. Then, when the external force is continuously applied, while the movable column 410 moves, it can drive the first locking lever 200 to rotate (clockwise). At this time, even if the self-suction component drives the second locking lever 420 to rotate, under the action of the third card slot 422, the second locking lever cannot apply an external force to the movable column 410, and thus cannot drive the second locking lever to rotate (counterclockwise). At this time, the manual release lever 430 applies an external force to the unlocking lever 100 again to make the unlocking lever 100 rotate, and then the complete unlocking of the door lock can be realized. This manual control method can quickly interrupt the rotation of the self-suction component to the first locking lever 200, enable the lock tongue to rotate to the unlocking state, and improve the operation convenience of the door lock system.

[0051] The above structure enables the self-suction component and the interruption component to not interfere with each other at all. That is to say, when the self-suction actuator fails, separate mechanical locking and unlocking can be realized, which further ensures the safety during the maintenance process.

[0052] Embodiment 2:

[0053] This embodiment provides an automotive door lock actuator mechanism with self-suction and interruption. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0054] As Figure 1 and Figure 2 shown, in this embodiment, it further includes:

[0055] A first reset member 500, arranged on the movable column 410, for providing a reset thrust for the first locking lever 200.

[0056] In this technical solution, the first reset member 500 is specifically a torsion spring. After the manual release lever 430 pushes the first locking lever 200 to rotate and the self-suction component pushes the first locking lever 200 to rotate, the first reset member 500 can enable it to quickly rotate to the initial position to facilitate the next operation.

[0057] Embodiment 3:

[0058] This embodiment provides an automotive door lock actuator mechanism with self - suction and interruption. In addition to including the technical solutions of the above - mentioned embodiment, it also has the following technical features.

[0059] As Figure 1 and Figure 2 shown, in this embodiment, the self - suction component includes: a rod portion 360, a sliding seat 370, and a power portion (not shown in the figure).

[0060] The rod portion 360 is provided with a thread along its length direction. The sliding seat 370 is arranged on the threaded section of the rod portion 360. The power portion is used to drive the rod portion to rotate, thereby driving the sliding seat 370 to perform a linear motion on the threaded section. By moving the sliding seat 370 left and right, the unlocking lever 100 and the first locking lever 200 are driven to rotate. For the specific structure of the power portion, there are many ways in the prior art to achieve it. Since the focus of the invention of this application is the interruption component, the self - suction component will not be described in too much detail here as long as it can be achieved.

[0061] The embodiments of the present application have been described above with reference to the accompanying drawings. Without conflict, the embodiments and the features in the embodiments in the present application can be combined with each other. The present application is not limited to the above - mentioned specific embodiments. The above - mentioned specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
