Description
Technical Field
[0001] The present invention belongs to the technical field of automotive door locks, and particularly relates to an automotive door lock system 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 lock tongues and achieve the locking and unlocking of the door locks 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 anti - pinch function of the door system 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 lock 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 engagement part to open the door lock. Although the above - mentioned automotive door lock can achieve the interruption during self - suction locking, its structure is complex and it is difficult to reduce the production cost.

[0060] Embodiment 1:
[0061] As Figures 1 - 6 shown, this embodiment provides an automotive door lock system with self - suction and interruption, including:
[0062] A locking tongue 100, rotatably arranged, having a first engaging portion 110 and a second engaging portion 120 thereon, which forms an unlocked state, a semi - locked state, and a fully - locked state according to its own position change;
[0063] A pawl 200, rotatably arranged, which, when rotating, disengages from the locking tongue 100 or presses against the locking tongue 100 according to the rotation direction;
[0064] A first locking lever 300, rotatably arranged, which drives the locking tongue 100 to rotate or disengages from the locking tongue 100 according to the rotation direction when rotating;
[0065] An unlocking lever 400, rotatably arranged, which is used to drive the pawl 200 to rotate when rotating, so that the pawl 200 disengages from the first engaging portion 110 and the second engaging portion 120 of the locking tongue 100;
[0066] Among them, when the locking tongue 100 rotates to make the first engaging portion 110 thereon engage with the pawl 200, the locking tongue 100 is in the fully - locked state; when the locking tongue 100 rotates to make the second engaging portion 120 thereon engage with the pawl 200; when the locking tongue 100 rotates to disengage the pawl 200 from the first engaging portion 110 and the second engaging portion 120, the locking tongue 100 is in the unlocked state; the door lock system further includes:
[0067] An actuator mechanism, the actuator mechanism includes:
[0068] The self - suction component is used to automatically control the rotation of the unlocking lever 400 to make the pawl 200 rotate; and is used to automatically control the rotation of the first locking lever 300 to drive the locking tongue 100 to rotate in the fully locked direction;
[0069] And the interruption component is used to manually control the rotation of the unlocking lever 400 and the first locking lever 300, and at the same time can control the self - suction component to interrupt the rotation of the first locking lever 300 so that the locking tongue 100 can rotate to the unlocking state.
[0070] In this technical solution, the locking tongue 100 is used to realize the unlocking and locking of the car tailgate. Under the action of the self - suction component, by rotating the first locking lever 300, the locking tongue 100 is locked, and by rotating the unlocking lever 400, the locking tongue 100 is unlocked. When the self - suction component fails, or in some external emergency situations during the self - suction of the door lock, such as when the finger is pinched when the tailgate strut anti - pinch fails or other situations where the self - suction process needs to be interrupted, the interruption component is required to realize the unlocking of the locking tongue 100.
[0071] Through the combination of the self - suction component and the interruption component, the automatic and manual control of the door lock system is realized. The self - suction component can automatically control the rotation of the unlocking lever 400 and the first locking lever 300, improving the convenience of unlocking and locking. The interruption component can be manually controlled when necessary to meet the usage requirements of the door lock in special situations.
[0072] Specifically, a first card slot 310 is opened on the first locking lever 300; the interruption component includes:
[0073] The movable column 521 is movably arranged on the first card slot 310 along the length direction of the first card slot 310;
[0074] The second locking lever 522 is rotatably arranged. A second card slot 5221 facing the first card slot 310 and a third card slot 5222 communicating with the second card slot 5221 are opened on the second locking lever 522. The movable column 521 also extends into the second card slot 5221;
[0075] And the manual release lever 523 is rotatably arranged and has two driving ends and one stress end;
[0076] Wherein, when the extended end of the movable column 521 is located in the second card slot 5221 and the self - suction component automatically drives the second locking lever 522 to rotate, the second locking lever 522 drives the movable column 521 and the first locking lever 300 to rotate;
[0077] When the manual release lever 523 rotates, one driving end of the manual release lever 523 is used to drive the unlocking lever 400 to rotate. At the same time, the other driving end of the manual release lever 523 is used to drive the movable column 521 to move, so that it moves from the second card slot 5221 to the third card slot 5222. When the movable column 521 slides in the third card slot 5222, it drives the first locking lever 300 to rotate at the same time, so that it moves in the direction away from the lock tongue 100.
[0078] In this technical solution, the first card slot 310 opened on the first locking lever 300, the second card slot 5221 opened on the second locking lever 522 opposite to the first card slot 310, and the third card slot 5222 communicated with the second card slot 5221. The movable column 521 extends into the second card slot 5221. These structures enable the movable column 521, the first locking lever 300 and the second locking lever 522 to cooperate with each other to realize the automatic and manual control of the door lock system.
[0079] In the process of automatic control, the self-suction component applies an external force to the second locking lever 522 and makes it rotate. The second locking lever 522 drives the movable column 521 and the first locking lever 300 to rotate. Then the first locking lever 300 drives the lock tongue 100 to rotate, that is, rotate clockwise. Among them, the pawl 200 gradually moves on the second engaging portion 120 until the pawl 200 engages on the first engaging portion 110, and finally realizes the full locking of the lock tongue 100.
[0080] The self-suction component applies an external force to the unlocking lever 400 and makes it rotate. The unlocking lever 400 drives the pawl 200 to rotate, so that the pawl 200 disengages from the lock tongue 100. At this time, the lock tongue 100 can rotate counterclockwise. When other external forces are used, after the lock tongue 100 rotates counterclockwise, the lock tongue 100 can be unlocked.
[0081] Regarding the structural setting of the interruption component, an important design point is the second locking lever 522. By opening a second card slot 5221 and a third card slot 5222 on the second locking lever 522, the third card slot 5222 is set as an arc slot, and the center of the arc slot is located on the rotation axis of the second locking lever 522. The first locking lever 300 is rotatably arranged coaxially with the second locking lever 522. The external force applied by the manual release lever 523 to the movable column 521 will cause the movable column 521 to move downward by a certain displacement, that is, from the second card slot 5221 to the third card slot 5222. Then, when the external force is continuously applied, while the movable column 521 moves, it drives the first locking lever 300 to rotate (clockwise). After the first locking lever rotates clockwise, it will no longer drive the lock tongue 100 to rotate clockwise. At this time, even if the self-suction component drives the second locking lever 522 to rotate, under the action of the third card slot 5222, the second locking lever cannot apply an external force to the movable column 521, and thus cannot drive the second locking lever to rotate (counterclockwise). At this time, applying an external force to the unlocking lever 400 by the manual release lever 523 to disengage the pawl 200 from the lock tongue 100 can achieve the complete unlocking of the lock tongue 100. This manual control method can quickly interrupt the rotation of the self-suction component on the first locking lever 300, enable the lock tongue 100 to rotate to the unlocking state, and improve the operation convenience of the door lock system.
[0082] 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 a failure occurs in the self-suction actuator, separate mechanical locking and unlocking can be achieved, further ensuring safety during the maintenance process.
[0083] As Figures 1 - 2 shown, in this embodiment, optimally, it further includes:
[0084] The first housing 600, and the lock tongue 100 and the pawl 200 are both arranged inside the first housing 600;
[0085] The second housing (700), and the first locking lever (300), the unlocking lever 400, and the actuator mechanism are all arranged inside the second housing;
[0086] Among them, the first housing 600 and the second housing 700 are of a split type, and the two are connected through a connection structure, and the included angle between the two after connection is adjustable.
[0087] In this technical solution, by setting the first housing 600 and the second housing 700, the entire door lock system can achieve dust and waterproof effects. For the angles of the first housing 600 and the second housing 700, adjust the installation angles according to the actual situation.
[0088] Embodiment 2:
[0089] This embodiment provides an automotive door lock system with self - suction and interruption. In addition to the technical solutions of the above - mentioned embodiment, it also has the following technical features.
[0090] In this embodiment, the actuator mechanism further includes:
[0091] A first reset member 530, disposed on the latch 100, for providing a reset thrust to the latch 100, and this thrust enables the latch 100 to move towards its unlocking - state position;
[0092] A second reset member 540, disposed on the pawl 200, for providing a reset thrust to the pawl 200, and this thrust can enable the pawl 200 to be pressed tightly against the latch 100;
[0093] A third reset member (not shown in the figure), disposed on the unlocking lever 400, for providing a reset thrust to the unlocking lever 400;
[0094] And a fourth reset member 550, disposed on the movable column 521, for providing a reset thrust to the first locking lever 300, and this thrust enables the first locking lever 300 to move in the direction away from the latch 100.
[0095] In this technical solution, the actuator mechanism further includes a first reset member 530, a second reset member 540, a third reset member, and a fourth reset member 550. The function of these reset members is to provide a reset thrust so that the latch 100, the pawl 200, the unlocking lever 400, and the first locking lever 300 can move towards their original states or unlocking states.
[0096] Specifically, each reset member is a torsion spring. Among them, when the pawl 200 disengages from the latch 100, the function of the first reset member 530 is to push the latch 100 towards the unlocking - state position and achieve unlocking. After the self - suction assembly is reset, the unlocking lever 400 no longer applies an external rotational force to the pawl 200. Subsequently, the second reset member 540 drives the pawl 200 to rotate clockwise, so that the pawl 200 is pressed tightly against the latch 100. After the self - suction assembly is reset, the unlocking lever 400 loses the external force. At this time, the third reset member drives the unlocking lever 400 to rotate and reset, so as to facilitate the next application of an external force to the unlocking lever 400 by the self - suction assembly. After the self - suction assembly is reset, the function of the fourth reset member 550 is to push the first locking lever 300 in the direction away from the latch 100, so as to facilitate the next application of an external force to the second locking lever 522 by the self - suction assembly.
[0097] Embodiment 3:
[0098] This embodiment provides an automotive door lock system with self - suction and interruption. In addition to the technical solutions of the above - mentioned embodiment, it also has the following technical features.
[0099] In this embodiment, the self - suction component includes:
[0100] A rod portion 5142, on which a threaded section is provided along its length direction;
[0101] A sliding nut seat 515, arranged on the threaded section of the rod portion 5142. When the rod portion 5142 rotates, the sliding nut seat 515 makes a linear motion on the threaded section;
[0102] And a power unit (not shown in the figure), used to drive the rotation of the rod portion 5142;
[0103] Wherein, the sliding nut seat 515 is located between the unlocking lever 400 and the second locking lever 522. When the sliding nut seat 515 makes a linear motion, it is used to drive the unlocking lever 400 or the second locking lever 522 to rotate.
[0104] In this technical solution, for the specific structure of the power unit, 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 as long as it can be achieved.
[0105] Embodiment 4:
[0106] This embodiment provides an automobile door lock system with self - suction and interruption. In addition to including the technical solution of the above - mentioned embodiment, it also has the following technical features.
[0107] In this embodiment, the actuator mechanism further includes: a control unit; the control unit includes:
[0108] A signal detection unit, used to detect signals and send the signals to the control unit;
[0109] And a control unit, according to the received signals, controls the operating state of the power unit, so that the sliding nut seat 515 moves towards the unlocking lever 400 or the second locking lever 522 or stops.
[0110] In this technical solution, specifically, the signal detection unit includes:
[0111] A micro - switch, which sends a signal to the control unit when it is turned on. There are two micro - switches, namely the first micro - switch 5171 and the second micro - switch 5172 respectively;
[0112] A pawl 518 lever, arranged on the pawl 200. When the pawl 200 rotates, the pawl 518 lever is used to control the opening or closing of the first micro - switch 5171;
[0113] And a latch lever 519, arranged on the latch 100. When the latch 100 rotates, the latch lever 519 is used to control the opening or closing of the second micro - switch 5172;
[0114] Wherein, when the lock tongue 100 rotates to the unlocked state, the position of the pawl 200 causes the pawl 518 lever to turn on the first micro switch 5171, and the lock tongue lever 519 pushes the second micro switch 5172 to turn on;
[0115] When the lock tongue 100 rotates to the half-locked state, the first micro switch 5171 is turned off and the second micro switch 5172 is turned on;
[0116] When the lock tongue 100 rotates to the fully locked state, the first micro switch 5171 is turned off and the second micro switch 5172 is turned off.
[0117] The unlocking and locking conditions of the vehicle tailgate are as follows.
[0118] When the vehicle tailgate is opened, the lock tongue 100 is in the unlocked state. When the operator manually closes the vehicle tailgate, if the hook lock on the vehicle tailgate directly hits the lock tongue 100 and causes the lock tongue 100 to rotate by a large angle, and the pawl 200 engages with the first engaging portion 110 of the lock tongue 100, it indicates that the lock tongue 100 fully locks the vehicle tailgate. At this time, the self-suction component will not be triggered to start. If the hook lock of the vehicle tailgate hits the lock tongue 100 and causes it to rotate until the pawl 200 engages with the second engaging portion 120, at this time, the lock tongue 100 is in the half-locked state, or the drive unit controls the vehicle tailgate to automatically close the door and makes the lock tongue 100 in the half-locked state. Then, the control unit, according to the signal of the second micro switch 5172, makes the power unit drive the sliding nut seat 515 to move to the right, and then applies a thrust to the second locking lever 522 through the sliding nut seat 515 to achieve automatic locking of the vehicle tailgate. After the lock tongue 100 rotates to the fully locked state, at this time, the control unit controls the power unit to stop, and then delays to start the power unit to make the sliding nut seat move to the left, so that the sliding nut seat 515 is reset. When releasing the unlocking signal to the control unit, the control unit controls the power unit to start, and drives the unlocking lever 400 to rotate through the sliding nut seat 515. The lock tongue 100 rotates to the unlocked state under the action of the first return spring.
