Description

Technical Field

[0001] The utility model relates to the technical field of automobile door locks, in particular to an automobile door lock suction and interruption mechanism and an automobile door lock. Background Art

[0002] Cars are a means of transportation that people often use in daily life. Cars are gradually becoming intelligent and electronic, making them more comfortable and convenient to use. The sense of experience has greatly increased, and the security of electronic information technology has been continuously enhanced. Electronically controlled door opening is a new type of car door lock with a simple and compact mechanical structure and good development prospects.

[0003] With the development of science and technology, the requirements for automation in automobiles are getting higher and higher. Various parts are improving the automation of the movement of parts and mechanisms to meet people's needs for operability, comfort, speed and convenience. The application of self-priming side door locks in passenger cars is gradually increasing. Compared with ordinary door locks, self-priming door locks increase functionality and comfort while also putting forward higher requirements for safety. When the car door lock is electrically closed, in the semi-locked state, there will be a gap of 6 to 10 mm between the car door and the door frame. There is a risk of the car door pinching fingers and clothes during the self-priming process.

[0004] Therefore, in the design of the electric self-closing door lock mechanism, it is necessary to provide a car door lock closing interruption mechanism. Specifically, when the passenger or driver realizes the danger during the door closing process and quickly pulls the outer or inner opening handle, the door lock mechanism must be able to unconditionally and reliably interrupt the self-closing process and mechanically disengage the relevant structure so that the door can be opened and the danger is eliminated.

[0005] Chinese patent publication number CN112065185A discloses an emergency disengagement mechanism for a self-priming door lock, which realizes the emergency disengagement function of the self-priming door lock by setting relatively independent self-priming units and emergency disengagement units. However, the related scheme has a relatively complex structure, involves many parts, has a high cost, and is not easy to assemble and use. Utility Model Content

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0045] like Figures 1 to 8 As shown, the present application discloses a vehicle door lock signal triggering mechanism, comprising:

[0046] A pawl assembly 1, a ratchet assembly 2 and a first drive device 9 are installed in the housing 5. The pawl assembly 1 and the ratchet assembly 2 form a fully locked state, a half-locked state and a fully opened state of the door lock under the action of the first drive device 9;

[0047] The signal switch 4 is fixedly arranged on the housing 5 and connected to the vehicle body controller;

[0048] The signal trigger rod 3, under the action of the rotating shaft device 6, the torsion spring device 7, the pawl assembly 1 and the ratchet assembly 2, disengages from the signal switch 4 only when the door lock is in a fully locked state, and the signal switch 4 performs a signal jump, wherein the torsion spring device 7 is arranged on a side of the signal trigger rod 3 close to the signal switch 4 and causes the end to rotate along the rotating shaft device 6 toward a side away from the signal switch 4.

[0049] The automobile door lock signal trigger mechanism disclosed in the present application is an improvement on the signal feedback structure of whether the existing automobile self-priming door lock structure is completely in a fully locked state. By setting a signal switch 4, when the ratchet assembly 2 of the automobile door lock moves to the fully locked state under the action of the first drive device 9, the pressing force of the ratchet assembly 2 and the signal trigger rod 3 is disengaged, the pawl assembly 1 is reset, and the signal trigger rod 3 is disengaged from the signal switch 4 under the action of the torsion spring device 7, so as to realize the jump of the signal switch 4, thereby outputting a signal feedback that the automobile door lock is in a fully locked state to the vehicle body controller. If the pawl assembly 1 or the pawl assembly 1 is in a non-fully locked state or the pawl assembly 1 is not reset due to ice in the fully locked state, the signal trigger rod 3 can still be pressed onto the signal switch 4 under the action of the torsion spring device 7, so that the signal switch 4 is in a pressed state. As an example of the present application, the signal switch 4 is in a fully locked state when the signal trigger rod 3 is pressed. The signal trigger rod 3 is in a normally connected state, and jumps to a disconnected state when the signal trigger rod 3 is separated from the signal switch 4, so that a group of signal switches 4 can be used to realize the signal feedback of whether the pawl assembly 1 and the ratchet assembly 2 in the automobile door lock are in a completely closed state in the fully locked state. The torsion spring device 7 is arranged on the side of the signal trigger rod 3 close to the signal switch 4, and the end is rotated along the shaft device 6 toward the side away from the signal switch 4, so that the layout of the entire trigger mechanism is more compact, which helps to optimize the use of internal space, while reducing unnecessary supporting structures and connecting parts, better resisting the interference of environmental factors, optimizing the overall design, and improving the accuracy and reliability of the signal trigger mechanism. Through the elastic force of the torsion spring device 7, the precise movement of the signal trigger rod 3 in different states (fully locked, half locked, fully open) is guaranteed, and the jump of the signal switch 4 is ensured to be accurate, and the correct door lock state information is transmitted to the body controller.

[0050] The automobile door lock signal triggering mechanism disclosed in the present application optimizes the structural design, simplifies the component assembly structure, reduces the cost, and improves the accuracy and reliability of signal feedback.

[0051] As a preferred example of the present application, the signal trigger rod 3 includes a ratchet crimping portion 301, a pawl crimping portion 302 and a first pin shaft hole 303, the first pin shaft hole 303 is sleeved on the rotating shaft device 6, the ratchet crimping portion 301 and the pawl crimping portion 302 are arranged on opposite sides of the first pin shaft hole 303, the ratchet crimping portion 301 is used for crimping and limiting the ratchet assembly 2 when the work position is changed, and the pawl crimping portion 302 is used for crimping and limiting the pawl assembly 1 when the work position is changed. In the fully locked state, the ratchet crimping portion 301 and the pawl crimping portion 302 are relatively disengaged from the pawl assembly 1 and the ratchet assembly 2 and rotate in a direction away from the signal switch 4. This design discloses a specific structure of a signal trigger rod 3, including a ratchet crimping portion 301, a pawl crimping portion 302 and a first pin shaft hole 303, which realizes precise limiting and signal feedback of the ratchet assembly 2 and the pawl assembly 1. The ratchet crimping portion 301 and the pawl crimping portion 302 interact with the ratchet assembly 2 and the pawl assembly 1 respectively, so as to establish a set of signal switches 4 to realize accurate detection of whether the ratchet assembly 2 and the pawl assembly 1 are in a fully locked state when the door lock is fully locked. At the same time, the signal trigger rod 3 is fixed to the rotating shaft device 6 through the first pin shaft hole 303, so that the ratchet crimping portion 301 and the pawl crimping portion 302 can move stably and accurately during operation, reducing errors caused by loose or misaligned parts. The entire assembly structure is relatively compact, reducing the number and complexity of parts, and helping to optimize the overall design of the door lock mechanism. In the semi-locked or fully open state, the ratchet crimping portion 3 01 and the pawl crimping part 302 will keep in contact with the ratchet assembly 2 and the pawl assembly 1 respectively, the signal trigger rod 3 is always in a state of non-rotation, and the signal switch 4 remains in a normal connected state until in the full-lock state, the ratchet crimping part 301 and the pawl crimping part 302 are relatively disengaged from the pawl assembly 1 and the ratchet assembly 2, and the signal trigger rod 3 rotates and moves away from the signal switch 4, triggering the signal jump, ensuring that the signal switch 4 timely and accurately feeds back the signal of the full-lock state, has strong anti-interference ability, can maintain a stable working state under various environmental conditions (such as vibration, icing, etc.), provides accurate signal feedback, and is convenient for maintenance personnel to inspect, repair and replace, reducing maintenance time and cost.

[0052] Through the precise design of the signal trigger rod 3, the automobile door lock signal trigger mechanism described in the present application simplifies the design, optimizes the structure, improves the accuracy of signal feedback and the environmental adaptability of the system, and facilitates maintenance and adjustment, thereby significantly improving the overall performance and user experience of the automobile door lock system.

[0053] As a preferred example of the present application, the pawl assembly 1 includes a pawl connecting rod pushing mechanism 105, and the ratchet assembly 2 includes a ratchet connecting rod pushing mechanism 205. The pawl connecting rod pushing mechanism 105 always acts on the pawl crimping portion 302 and crimps it to the signal switch 4 in a non-fully locked state, and the ratchet connecting rod pushing mechanism 205 always acts on the ratchet crimping portion 301 in a non-fully locked state and drives the pawl crimping portion 302 to be crimped to the signal switch 4. In the example of the present application, in the fully locked state, the pawl crimping portion 302 and the ratchet crimping portion 301 on the signal trigger rod 3 are disengaged from the pawl connecting rod pushing mechanism 105 and the ratchet connecting rod pushing mechanism 205, and the signal trigger rod 3 is disengaged from the signal switch 4 under the action of the rotating shaft device 6 and the torsion spring device 7. As a specific example of the present application, a ratchet connecting rod pushing mechanism 205 is provided on the ratchet assembly 2, so that when the ratchet assembly 2 moves from a fully open state or a semi-locked state to a fully locked state under the action of the first driving device 9, the ratchet connecting rod pushing mechanism 205 is always pressed against the ratchet pressing portion 301 of the signal trigger rod 3 under the rotation of the ratchet assembly 2, and the signal trigger rod 3 is pressed against the signal switch 4 to overcome the force of the torsion spring device 7, until the ratchet assembly 2 moves to the fully locked state, and the ratchet connecting rod pushing mechanism 205 is not pressed against the ratchet pressing portion 301 is relatively disengaged, and at this time, if the pawl assembly 1 is reset, the pawl connecting rod pushing mechanism 105 on the pawl assembly 1 is disengaged from the pawl crimping portion 302 of the signal trigger rod 3, and the signal trigger rod 3 and the pawl connecting rod pushing mechanism 105 and the ratchet connecting rod pushing mechanism 205 are all in the disengaged state, the pawl crimping portion 302 can be rotated to the side away from the signal switch 4 under the action of the rotating shaft device 6 and the torsion spring device 7, and then with the signal switch 4, otherwise, the pawl crimping portion 302 is always in a state of being pressed on the signal switch 4, and no signal jump occurs.

[0054] The above-mentioned setting realizes precise control and signal feedback of the signal trigger rod 3 by respectively arranging the pawl connecting rod pushing mechanism 105 and the ratchet connecting rod pushing mechanism 205 on the pawl assembly 1 and the ratchet assembly 2, thereby avoiding the risk of false alarm of the full lock state, improving the reliability and safety of the system, and optimizing the structural design, improving the user experience and maintenance convenience.

[0055] As a preferred example of the present application, a limit device 8 is provided on the housing 5, and the limit device 8 is used to limit the position of the pawl crimping portion 302 on the signal trigger rod 3 when it rotates toward the side away from the signal switch 4 under the action of the torsion spring device 7. As an example of the present application, the limit device 8 is a boss structure provided on the housing 5, one side of the torsion spring device 7 is fixed to the limit device 8, and the other end is fixed to the pawl crimping portion 302, which is used to limit the rotation position of the pawl crimping portion 302 in the fully locked state, prevent the signal trigger rod 3 from causing signal feedback errors due to excessive or insufficient rotation, avoid damage to the signal switch 4 or other components, and improve the reliability and durability of the entire door lock signal trigger mechanism.

[0056] Through this structural design, the accuracy and stability of signal feedback are guaranteed, the design and installation process are simplified, the torsion spring device works more effectively, the system's anti-interference ability is enhanced, the performance and user experience of the car door lock signal trigger mechanism are effectively improved, and accurate and reliable signal feedback is ensured under various working conditions.

[0057] As a preferred example of the present application, the ratchet crimping portion 301 includes a rotating crimping portion 3011 and a first avoidance groove 3012. The rotating crimping portion 3011 is arranged in an arc shape, and the first avoidance groove 3012 is an avoidance portion recessed along the tangent direction of the rotating crimping portion 3011 toward the center of the arc. When the door lock is in a fully locked state, the ratchet connecting rod pushing mechanism 205 slides into the first avoidance groove 3012 and disengages from the signal trigger rod 3. The above-mentioned setting discloses a specific structure of a ratchet crimping part 301, including a rotating crimping part 3011 and a first avoidance groove 3012. The rotating crimping part 3011 is arranged in an arc shape, so that the ratchet link pushing mechanism 205 always maintains crimping contact with the rotating crimping part 3011 in a non-fully locked state, ensuring that the signal trigger rod 3 is crimped on the signal switch 4 in a non-fully locked state, ensuring the smooth movement of the signal trigger rod 3 during rotation, reducing friction and wear, and improving the durability and stability of the component. The first avoidance groove 3012, which is recessed along the tangent direction of the rotating crimping part 3011 toward the center of the arc, realizes the avoidance of the ratchet link pushing mechanism 205 when the ratchet component 2 moves to the fully locked state of the door lock, realizes the relative separation of the ratchet link pushing mechanism 205 and the signal trigger rod 3, prevents false triggering due to vibration or other interference in the fully locked state, improves the reliability and anti-interference ability of the system, and ensures accurate and reliable signal feedback.

[0058] As a preferred example of the present application, the ratchet crimping portion 302 includes a first mounting plate 3021 and a crimping boss 3022, the first mounting plate 3021 and the crimping boss 3022 are arranged in a step shape, the first mounting plate 3021 is used to install and fix the torsion spring device 7, the signal switch 4 and the ratchet connecting rod pushing mechanism 105 can respectively abut against the opposite sides of the crimping boss 3022 along the rotation direction of the ratchet crimping portion 302. The above-mentioned setting discloses a specific structure of a ratchet crimping portion 302, by designing a ratchet crimping portion 302 including a first mounting plate 3021 and a crimping boss 3022 arranged in a step shape, the first mounting plate 3021 is used to fix the torsion spring device 7, and provides a stable mounting base, ensuring that the torsion spring device 7 can stably apply force during operation, maintain the normal operation of the signal trigger rod 3, and avoid unstable operation caused by loosening or displacement of the torsion spring device 7; the crimping boss 3022 and the first mounting plate 3021 are arranged in a step shape, so that the ratchet connecting rod pushing mechanism 105 and the signal switch 4 can respectively abut against the opposite sides of the crimping boss 3022 along the rotation direction of the ratchet crimping portion 302, thereby making the force transmission path clearer and more concentrated, ensuring that the signal trigger rod 3 can accurately rotate and position when subjected to force, thereby improving the working accuracy of the signal trigger rod 3, further simplifying the overall design, and reducing the complexity of manufacturing and assembly. As an example of the present application, the ratchet crimping portion 302 is roughly rhombus-shaped, and a transition arc is provided at the connection between the abutting edges on both sides.

[0059] As a preferred example of the present application, the pawl assembly 1 further includes a pawl 101, a first torsion spring 102, a first pin 103 and a pawl link 104. The pawl 101 and the pawl link 104 are connected as a whole through the first torsion spring 102 and the first pin 103. The pawl link pushing mechanism 105 is integrally arranged on the pawl link 104 at the end close to the pawl crimping portion 302. This design integrates the pawl 101 and the pawl link 104 through the first torsion spring 102 and the first pin 103 to form a complete mechanism, thereby enhancing the overall rigidity and reliability of the assembly, reducing the number of independent components, and reducing the failure rate of the system. The pawl link pushing mechanism 105 is integrally arranged on the pawl link 104 to ensure that the pawl link pushing mechanism 105 can accurately act on the pawl crimping portion 302 of the signal trigger rod 3 when the pawl assembly 1 is in the working state, providing a clear crimping or disengagement action, and ensuring the accuracy of the signal feedback.

[0060] As a preferred example of the present application, the ratchet assembly 2 includes a ratchet 201, a second torsion spring 202, a second pin 203 and a ratchet link 204. The ratchet 201 and the ratchet link 204 are connected as a whole through the second torsion spring 202 and the second pin 203. The ratchet link pushing mechanism 205 is integrally arranged on the end of the ratchet link 204 close to the ratchet crimping portion 301. The design discloses a specific structure of a ratchet assembly 2, which improves the overall rigidity and reliability of the ratchet assembly 2. The modular integrated design reduces the number of independent components and the complexity of installation, making the system design more concise and efficient. The ratchet link pushing mechanism 205 is arranged on the side close to the signal switch 4, so that it can always apply force to the ratchet crimping portion 301 of the signal trigger rod 3 in a non-fully locked state, preventing the signal from being triggered by mistake, ensuring that it will only be disengaged in a fully locked state, and achieving accurate signal feedback.

[0061] The automobile door lock signal trigger mechanism disclosed in the present application mainly includes a ratchet assembly 2, a pawl assembly 1, a signal trigger rod 3 and a signal switch 4. The pawl assembly 1 includes a pawl connecting rod pushing mechanism 105, and the ratchet assembly 2 includes a ratchet connecting rod pushing mechanism 205. In the fully locked state, the signal trigger rod 3 is disengaged from the pawl connecting rod pushing mechanism 105 and the ratchet connecting rod pushing mechanism 205, and the signal trigger rod 3 is disengaged from the signal switch 4 under the action of the torsion spring device 7 and the limit device 8.

[0062] When the door lock is in the fully locked state, the ratchet connecting rod pushing mechanism 205 in the ratchet assembly 2 slides into the first avoidance groove 3012 in the signal trigger rod 3, the pawl connecting rod pushing mechanism 105 in the pawl assembly 1 rotates counterclockwise, and the signal trigger rod 3 rotates counterclockwise under the action of the torsion spring device 7 to disengage from the signal switch 4.

[0063] When the door lock is self-priming from the semi-locked state to the fully locked state, if the pawl connecting rod pushing mechanism 105 in the pawl assembly 1 does not move to the locked working position, the pawl connecting rod pushing mechanism 105 in the pawl assembly 1 is pressed on the signal trigger rod 3 and the pawl pressing part 302 of the signal trigger rod 3 is pressed on the signal switch 4, such as Figure 5 The structure shown.

[0064] The automobile door lock signal trigger mechanism described in the present application can accurately and reliably provide feedback on whether the automobile door lock is in a fully closed (fully locked) state: the ratchet assembly 2 will continue to push the signal trigger rod 3 to compress the signal switch 4 before full locking; only when the ratchet assembly 2 is in the fully locked position and the pawl assembly 1 is in a position to prevent the pawl from opening, the signal switch 4 will jump; otherwise, it has been pressed before (the ratchet assembly 2 is acting or the pawl assembly 1 is acting).

[0065] When the ratchet assembly 2 is in the open or semi-locked position, the ratchet crimping portion 301 of the signal trigger rod 3 can be pressed by the ratchet link pushing mechanism 205, thereby pressing the signal switch 4; in the process of the ratchet assembly 2 going from semi-locked to fully locked, the ratchet link pushing mechanism 205 no longer presses the signal trigger rod 3 after the ratchet 201 reaches the fully locked position.

[0066] Only when the pawl link pushing mechanism 105 is in the position to prevent the ratchet wheel 201 from opening, the signal switch 4 is not pressed and the signal jumps, that is, the feedback indicates that the vehicle door has been reliably closed.

[0067] The automobile door lock signal trigger mechanism disclosed in the present application optimizes the structure of the ratchet assembly 2, the pawl assembly 1 and the signal trigger rod 3. Through a set of signal switches, when the ratchet assembly 2 and the pawl assembly 1 move normally to the locked state, a locking signal is fed back to the entire vehicle structure. It can accurately and reliably feedback whether the automobile door is in a completely closed state. It has a compact structure and can determine the full lock state signal in a relatively small stroke. It has high accuracy, improves the stability, reliability and user experience of the system, and provides effective protection for the safety and comfort of the vehicle.

[0068] like Figures 8 to 12 As shown, the present application discloses a vehicle door lock suction interruption mechanism, comprising:

[0069] The pawl assembly 1 is rotatably arranged, and when it rotates, it is separated from the lock tongue, or pressed against the lock tongue according to the rotation direction, forming an unlocked state, a semi-locked state, and a fully locked state;

[0070] The ratchet assembly 2 is rotatably arranged, and when rotating, it can push the pawl assembly 1 and the lock tongue to self-absorb and lock;

[0071] A self-priming push rod 14, which, under the driving action of the first driving device 9, can push the ratchet assembly 2 to rotate to perform the self-priming locking function;

[0072] Releasing the associated rod 11 can drive the self-priming interruption connecting rod 13 to slide under the action of the interruption assembly. The self-priming interruption connecting rod 13 disengages the self-priming push rod 14 from the ratchet assembly 2 during the sliding process, thereby realizing self-priming interruption.

[0073] In the present application, a pawl assembly 1 and a ratchet assembly 2 are provided which can rotate relative to each other. According to different rotation directions, the pawl assembly 1 and the ratchet assembly 2 can be separated from the lock tongue (forming an unlocked state), pressed against the lock tongue (forming a fully locked state), or between the two (forming a semi-locked state). The above functions and implementation methods have already belonged to the prior art of the automobile door lock structure with a self-priming function, and will not be described in detail here. The automobile door lock suction interruption mechanism described in the present application is optimized and improved for the above structure. By setting a release-related rod 11 in the housing 5 of the automobile door lock, when it is necessary to interrupt the self-priming lock (such as when the passenger or driver realizes the danger during the door closing process), the interruption assembly (such as an emergency release handle or sensor or door handle, etc.) will act, so that the release-related rod 11 drives the self-priming interruption link 13 to slide horizontally and / or in an arc shape under the action of the interruption assembly. During the sliding process, the self-priming interruption link 13 separates the self-priming push rod 14 from the ratchet assembly 2, so that the ratchet assembly 2 no longer pushes the pawl assembly 1 and the lock tongue to self-prime and lock, thereby realizing the self-priming interruption function.

[0074] The automobile door lock suction and interruption mechanism disclosed in the present application realizes the automatic closing and locking of the door and the self-suction interruption function in emergency situations through a simple mechanical structure. It has a compact structure and reliable operation, thereby improving the safety, reliability and convenience of the automobile door lock.

[0075] As a preferred example of the present application, the release-associated rod 11 is arranged on the side of the ratchet assembly 2 away from the first drive device 9, and an arc-shaped abutment portion 1302 is arranged on the self-priming interruption connecting rod 13, and a self-priming interruption rivet 15 is arranged on the self-priming push rod 14. The arc-shaped abutment portion 1302 can push the self-priming interruption rivet 15 to rotate toward the side away from the ratchet assembly 2 under the driving action of the release-associated rod 11. By arranging the release-associated rod 11 on the side of the ratchet assembly 2 away from the first drive device 9, the reliability of the self-priming function and the self-priming interruption function is guaranteed, so that when the self-priming lock needs to be interrupted, the release-associated rod 11 can directly and effectively interact with the self-priming interruption link 13 without being interfered by the first drive device 9, so that during the pushing process, the resistance can be reduced while ensuring the accuracy and reliability of the pushing, and at the same time, the spatial structure layout inside the car door lock is optimized. The structural design between the release-associated rod 11, the self-priming interruption link 13 and the self-priming push rod 14 is compact and reasonable, which not only ensures the realization of the function, but also saves space, making the entire door lock system more compact and lightweight.

[0076] The above settings achieve the effects of efficient interruption, compact structure and good stability through reasonable layout and sophisticated design, providing a strong guarantee for the safety of car door locks.

[0077] As a preferred example of the present application, the release-associated rod 11 is rotatably arranged and can be reset under the action of a reset device, and the self-priming interruption link 13 is fixedly connected at one end thereof, and a first guide slot 1301 is arranged on the self-priming interruption link 13, and the first guide slot 1301 can slide along the guide boss 16. As a specific example of the present application, the release-associated rod 11 is hingedly fixed on the housing 5 and a reset torsion spring is arranged on its hinge shaft, and the release-associated rod 11 rotates and moves under the action of the interruption component and drives the self-priming interruption link 13 to rotate and slide to one side, combined with the guide boss 16 arranged on the housing 5, the first guide slot 1301 arranged on the self-priming interruption link 13 is sleeved on the guide boss 16, so that it is limited and guided by the guide boss 16 when rotating and sliding, and after the self-priming interruption function ends, the interruption component stops working, and the release-associated rod 11 returns to its original position under the action of the reset torsion spring. Through the above-mentioned structural setting, the linkage function of the release-related rod 11 and the self-priming interruption link 13 is realized, and the guide sliding setting of the self-priming interruption link 13 ensures that it can move along a predetermined path when rotating and sliding, thereby increasing the stability and accuracy of the mechanism, the structure is ingenious, and the use is reliable.

[0078] As a preferred example of the present application, the interruption assembly includes a second drive device 10, and the second drive device 10 can electrically drive the release-associated rod 11 to rotate. As a specific example of the present application, the second drive device 10 includes a second drive motor 1001, a second transmission mechanism 1002, and an electric release link 1003, and the electric release link 1003 is driven to rotate by the second drive motor 1001 through the second transmission mechanism 1002, and the electric release link 1003 is engaged with the release-associated rod 11. Specifically, when the self-priming interruption function is executed, the release-associated rod 11 rotates counterclockwise under the driving action of the second drive motor 1001 and the second transmission mechanism 1002, and the self-priming interruption link 13 is connected to the meshing end of the release-associated rod 11 away from the electric release link 1003, so that the self-priming interruption link 13 moves to the right, thereby pushing the self-priming interruption rivet 15 on the self-priming push rod 14 to move to the right, and the first limiting groove 1401 on the self-priming push rod 14 is relatively disengaged from the first boss 206 on the ratchet assembly 2, realizing the self-priming interruption and ending the self-priming function. This setting discloses an electrically driven interruption component structure, which can ensure the precise movement of the self-priming interruption link 13 and the self-priming push rod 14 through the precise control of the motor and the transmission mechanism, thereby improving the accuracy and reliability of the interruption. At the same time, the structure can quickly respond to the control signal, realize the rapid interruption of the self-priming function, and improve the automation level of the system.

[0079] As a preferred example of the present application, the interruption assembly includes an outer opening link 12, the outer opening link 12 is connected to the inner handle and / or the outer handle, and the inner handle or the outer handle can drive the release-related rod 11 to rotate through the outer opening link 12. In the example of the present application, the inner handle or the outer handle can drive the outer opening link 12 to rotate counterclockwise, and the outer opening link 12 drives the release-related rod 11 to rotate counterclockwise, so that the self-priming interruption link 13 moves to the right, thereby pushing the self-priming interruption rivet 15 on the self-priming push rod 14 to move to the right, and the first limiting groove 1401 on the self-priming push rod 14 is relatively disengaged from the first boss 206 on the ratchet assembly 2. This setting discloses a mechanical structure and an interruption assembly associated with a door handle. In an emergency, the user can manually control the self-priming interruption function by directly operating the inner handle or the outer handle. It can be reliable and practical in harsh environments or when the electric function fails, and has the advantages of rapid response, high reliability and good safety.

[0080] As a preferred example of the present application, the outer opening connecting rod 12 is connected to the release-related rod 11 as a whole through the boss. The outer opening connecting rod 12 and the release-related rod 11 are connected by the boss to form an integrated structure, which makes the entire mechanism more compact in structure and reduces unnecessary space occupation. At the same time, the boss connection method can ensure that the connection between the two components is firm and not prone to loosening or misalignment, thereby improving the stability of the entire mechanism. In addition, this design helps the outer opening connecting rod 12 to be operated (such as manually operating the inner handle or outer handle) when its movement can be quickly and accurately transmitted to the release-related rod 11, reducing the transmission loss in the intermediate link, improving the transmission efficiency, and making the entire mechanism respond faster and able to respond quickly to operating instructions.

[0081] As a preferred example of the present application, the self-priming interrupting rivet 15 is arranged on the end of the self-priming push rod 14 away from its rotating hinge axis. As a specific example of the present application, the self-priming interrupting rivet 15 is arranged at the end of the self-priming push rod 14, and a first limiting groove 1401 is arranged near the end for abutting and connecting with the first boss 206 on the ratchet assembly 2 when performing the self-priming function. This setting realizes a direct and effective self-priming interrupting mechanism by optimizing the position and layout of the self-priming interrupting rivet 15 and the first limiting groove 1401, improves the stability of the self-priming function, simplifies the structure and operation, optimizes space utilization, and improves the response speed and sensitivity, thereby improving the performance and user experience of the entire mechanism.

[0082] In the example of the present application, the first driving device 9 includes a first driving motor 91, a first transmission mechanism 92 and a sector transmission gear 93, the self-priming push rod 14 is hingedly fixed on the side of the sector transmission gear 93 away from the sector meshing, and the sector transmission gear 93 rotates under the driving action of the first driving motor 91 and the first transmission mechanism 92. This setting realizes precise control and efficient power transmission of the self-priming push rod 14 through the coordinated use of the first driving motor 91, the first transmission mechanism 92 and the sector transmission gear 93, simplifies the structure and has good stability.

[0083] The automobile door lock pushes the self-priming push rod 14 under the action of the first driving device 9. The first driving device 9 includes a first driving motor 91 (self-priming motor). When the first driving motor 91 is working, the self-priming push rod 14 is pushed through the first transmission mechanism 92 (self-priming gear set) and the fan-shaped transmission gear 93. The self-priming push rod 14 pushes the ratchet 201 from half-lock to full-lock. The process of the ratchet 201 from half-lock to full-lock corresponds to the process of the car door from slightly open to completely closed. If a finger is caught by the car door when it is slightly open, there will be risks.

[0084] The automobile door lock closing interruption mechanism disclosed in this application is an optimization and improvement made for the clamping problem that occurs when the door is slightly opened to fully closed. This mechanism interrupts the automatic closing in two ways to avoid the risk of pinching the hand:

[0085] 1. Electric opening drives self-priming interruption: The second driving motor 1001 drives the second transmission mechanism 1002, the electric release link 1003 and the release associated rod 11, thereby pushing the self-priming interruption link 13 to drive the self-priming interruption rivet 15 on the self-priming push rod 14 to move to the side away from the ratchet 201, and then pushes the self-priming push rod 14 away to interrupt the suction process.

[0086] 2. Mechanical emergency handle self-priming interruption: the inner handle or outer handle is connected to the outer opening connecting rod 12. Pulling the outer opening connecting rod 12 can drive the release of the associated rod 11, push the self-priming interruption connecting rod 13 through the self-priming interruption rivet 15 to push the self-priming push rod 14 open, and interrupt the suction process.

[0087] The automobile door lock closing and interrupting mechanism described in the present application effectively avoids the risk of hand pinching during the automatic closing process of the car door from slightly open to fully closed through two innovative methods: electric opening driven self-priming interruption and mechanical emergency handle self-priming interruption. Whether it is the electric opening method driven by the second drive motor or the mechanical method of pulling the inside and outside handles, the self-priming interruption connecting rod can be quickly pushed to drive the self-priming interruption rivet on the self-priming push rod to move to the side away from the ratchet, thereby pushing the self-priming push rod open and interrupting the automatic closing process, ensuring the safety of the car door during the closing process and the convenience of user operation. It has a compact structure and is reliable to use, which not only improves the safety performance of the automobile door lock, but also improves the user experience.

[0088] like Figures 1 to 13 As shown, the utility model discloses a car door lock, including a shell 5 formed by a base 501, an upper cover 503 and a side cover 502 that are detachably connected, and the car door lock suction and interruption mechanism as described in Example 2 and / or the car door lock signal triggering mechanism as described in Example 1 are installed inside and outside the shell 5.

[0089] The automobile door lock disclosed in the present application is an improvement on the existing suction door lock, and the structure of the automobile door lock suction interruption mechanism is mainly integrated inside the door lock, which has a compact structure and reduces the number of parts.
