[0002] Car door locks are an important part of the car body. They are special parts that integrate safety, decoration and craftsmanship. With the development of the automobile industry, the functions and types of car door locks are becoming more and more diverse. Passengers have more and more knowledge about cars and have higher and higher requirements for car comfort. Among them, for car doors, humanized opening and closing has received more and more attention from customers and vehicle companies.

[0003] Most traditional car door locks are equipped with self-priming door locks. The so-called self-priming door locks can automatically lock the door to the fully locked position when the door is not completely closed (in a semi-locked state), thereby ensuring that the door is in a safely closed state. However, if the self-priming function is abnormal or in an emergency (such as when a child's finger is caught by the door), it is necessary to interrupt the self-priming process of the door lock. With regard to the current existing technology, some car doors do not have a self-priming interruption mechanism for outward opening, and most of the self-priming mechanisms have a complex structure, which not only easily leads to a larger door lock size and increases the occupancy of the car's interior space, but also has poor stability in interrupting the self-priming action and cannot meet the user's usage requirements.

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figures 1 to 4As shown, the utility model is a self-priming interruption mechanism of a car door lock, comprising: a base plate 1 for mounting parts, a lock tongue 2 and a self-priming push rod 3 are movably arranged on the base plate 1, and the self-priming push rod 3 is movably pressed against the lock tongue 2 to rotate the lock tongue 2 to reach a fully locked state; a transmission assembly 4 is arranged on the side of the base plate 1 away from the lock tongue 2, an outer opening arm 40 is rotatably arranged on one end of the transmission assembly 4, and an interruption arm 41 is rotatably arranged on the other end, and the interruption arm 41 is movably pressed against the self-priming push rod 3; an outer opening pull wire 5 is movably arranged on the base plate 1, one end of the outer opening pull wire 5 extends out of the base plate 1 and is connected to the car door, and the other end is movably connected to the outer opening arm 40; the outer opening arm 40 can drive the transmission assembly 4 to rotate when the outer opening pull wire 5 is pulled, so that the interruption arm 41 can push the self-priming push rod 3 away from the lock tongue 2 to interrupt the self-priming action of the car door.

[0035] refer to Figures 1 to 3 In the normal closing process of the door, the self-priming push rod 3 can move against the lock tongue 2, so that the lock tongue 2 rotates from the initial state (not shown in the figure) to Figure 1 The fully locked state shown in the figure can then be achieved, thereby realizing the closing of the vehicle door; and in this process, the present scheme provides an outer opening pull wire 5 connected to the vehicle door on the substrate 1, so that during the self-priming process of the vehicle door (that is, the self-priming push rod 3 is in the initial position at this time and has not yet abutted against the lock tongue 2), it only needs to pull the outer opening pull wire 5 to drive the outer opening arm 40 at one end of the transmission component 4 to rotate. As the transmission component 4 transmits the rotational torque, the interruption arm 41 finally pushes the self-priming push rod 3 away from the lock tongue 2 during the rotation process. That is to say, by changing the original moving trajectory of the self-priming push rod 3, the self-priming push rod 3 at this time can no longer apply the force to rotate the lock tongue 2 to reach the fully locked state, which has the effect of preventing pinching injuries in emergency situations. The overall structure of the self-priming interruption mechanism is relatively simple, and the rotational torque is stably transmitted through the transmission component 4, which saves the space occupied by the door lock, and also provides a guarantee for the stability of the interruption of the self-priming action, ensuring that it can meet the user's usage requirements.

[0036] Preferably, the present solution also has a self-priming push rod rivet shaft 30 connected to the self-priming push rod 3, and an arc-shaped raised surface 410 is formed on the interrupt arm 41. The arc-shaped raised surface 410 is movably pressed against the self-priming push rod rivet shaft 30, thereby ensuring that the interrupt arm 41 can smoothly push the self-priming push rod 3 away from the lock tongue 2 during the rotation process, thereby further improving the accuracy and stability of the interruption of the self-priming action of the car door.

[0037] The transmission assembly 4 also includes: an inner-outer conversion arm 42 and an interruption link 43. The inner-outer conversion arm 42 is rotatably arranged on the base plate 1, one end of the inner-outer conversion arm 42 is connected to the external electric release device, and the other end is movably pressed against the interruption link 43; one end of the interruption link 43 is movably clamped on the base plate 1, and the other end is away from the inner-outer conversion arm 42 and connected to the interruption arm 41; a clutch arm 44 is rotatably arranged on the base plate 1, and the clutch arm 44 passes through the inner-outer conversion arm 42, so that one side of the clutch arm 44 is movably pressed against the external opening arm 40, and the other side is movably pressed against the inner-outer conversion arm 42.

[0038] like Figures 2 to 4 As shown, when the outer opening wire 5 is pulled, the outer opening arm 40 can be driven to rotate around Figure 3 The clutch arm 44 passes through the inner-outer conversion arm 42 and is pressed against the outer opening arm 40, so that the outer opening arm 40 can push the clutch arm 44 to rotate at the first time during the rotation process, thereby pushing the inner-outer conversion arm 42 to rotate synchronously. It is also because the inner-outer conversion arm 42 is pressed against the interruption link 43 that the interruption link 43 can be pushed along the inner-outer conversion arm 42. Figure 3 Move to the left, thereby pushing the interruption arm 41 along Figure 3 During the clockwise rotation, the self-priming push rod 3 is moved away from the lock tongue 2 to prevent the self-priming push rod 3 from pushing the lock tongue 2 to the fully locked state during the movement. At the same time, this also realizes the interruption function of the self-priming action of the car door.

[0039] It should be noted that the present solution integrates the inner and outer conversion arms 42, the clutch arm 44 and the outer opening arm 40 for installation design, which not only saves the space occupied by the door lock, but also can utilize the inner and outer conversion arms 42 to be connected with an external electric release device (not shown in the figure, the electric release structure of the traditional technology can be adopted, the working principle is the same, and it will not be repeated here), so that the inner and outer conversion arms 42 can also be driven to rotate by electric release inside the vehicle, and then the self-closing action can be interrupted when the interruption link 43 is pushed to move, which provides double protection for realizing the anti-pinch function both inside and outside the vehicle in emergency situations. The overall structure is simple, and the stability of the interruption of the self-closing action is effectively guaranteed through the transmission of the rotational torque.

[0040] A U-shaped groove 420 is formed on the inner and outer conversion arm 42, and a driving portion 400 flush with one side wall of the U-shaped groove 420 is formed at the end of the outer opening arm 40, and a pushing portion 440 is formed at the bottom of the clutch arm 44. The pushing portion 440 passes through the U-shaped groove 420, so that one end of the pushing portion 440 is synchronously pressed against the driving portion 400 and one side wall of the U-shaped groove 420, and the other end is pressed against the other side wall of the U-shaped groove 420.

[0041] like Figure 3 and Figure 4As shown, for the integrated installation method between the inner and outer conversion arm 42, the clutch arm 44 and the outer opening arm 40, the solution is provided with a U-shaped groove 420 on the inner and outer conversion arm 42. In the initial installation state, the outer opening arm 40, the inner and outer conversion arm 42 and the clutch arm 44 are in Figure 4 The U-shaped groove 420 is installed on the base plate 1 from bottom to top. At the same time, one side of the U-shaped groove 420 is flush with the end of the driving part 400, and the other side is pressed against the pushing part 440 of the clutch arm 44. On the one hand, this structural design is conducive to the installation and disassembly of parts and components, and also provides convenience for the subsequent maintenance and replacement of parts and components. On the other hand, when the above-mentioned outer opening pull wire 5 is pulled to drive the outer opening arm 40 to rotate, the close contact between the structures can ensure that the clutch arm 44 and the inner and outer conversion arm 42 can rotate at the first time, effectively avoiding the phenomenon of working delay and the like during the operation of the self-priming interruption mechanism, and greatly ensuring the smoothness and stability of the interruption of the self-priming action.

[0042] A track groove 10 is formed on the base plate 1, and the end of the interruption link 43 away from the interruption arm 41 is connected to a locking column 430, the inner and outer conversion arm 42 movably abuts against the locking column 430, and the locking column 430 movably engages in the track groove 10 to guide the interruption link 43 to push the interruption arm 41 to rotate.

[0043] like Figure 2 and Figure 3 As shown, when the above-mentioned inner and outer conversion arms 42 push the interrupt link 43 to move during the rotation process, the active engagement between the locking column 430 and the track groove 10 can be relied upon to guide and limit the movement of the interrupt link 43, thereby ensuring the smoothness and stability of the interrupt link 43 when driving the interrupt arm 41 to rotate, and effectively ensuring that the interrupt arm 41 pushes the self-priming push rod 3 away from the lock tongue 2 during the rotation process to achieve a stable interruption effect of the self-priming action.

[0044] A first rivet shaft 11 is installed on the base plate 1, and the inner and outer conversion arm 42, the outer opening arm 40 and the clutch arm 44 are rotatably connected to the first rivet shaft 11, and a first torsion spring 110 is arranged on the first rivet shaft 11, an extension column 441 is formed on the clutch arm 44, and a limiting portion 431 is formed on the interrupt link 43, one end of the first torsion spring 110 is tightly pressed against the limiting portion 431, and the other end is connected to the extension column 441.

[0045] like Figures 2 to 4As shown, in order to facilitate the installation of the internal and external conversion arm 42, the external opening arm 40 and the clutch arm 44, the present solution is provided with a first rivet shaft 11 on the base plate 1, and the first rivet shaft 11 is used to realize that the above-mentioned parts all rotate relative to the base plate 1 around the first rivet shaft 11, ensuring the smoothness and stability of the various parts when connecting the rotation steps, and at the same time, the first torsion spring 110 on the first rivet shaft 11 is used, so that after the above-mentioned interruption self-suction action is completed, the first torsion spring 110 can effectively ensure that the clutch arm 44 can be reset to the initial position, so as to be used for the normal use of the subsequent self-suction interruption action. It is worth noting that since the pushing portion 440 on the clutch arm 44 passes through the U-shaped groove 420 of the internal and external conversion arm 42 and movably abuts against the driving portion 400 on the external opening arm 40, during the resetting process of the clutch arm 44 through the above-mentioned first torsion spring 110, it can also push the internal and external conversion arm 42 and the external opening arm 40 to realize the resetting function.

[0046] A second rivet shaft 13 is also installed on the base plate 1, and the interrupter arm 41 is rotatably connected to the second rivet shaft 13, and a second torsion spring 130 is arranged on the second rivet shaft 13, one end of the second torsion spring 130 is connected to the base plate 1, and the other end is connected to the end of the interrupter link 43 away from the inner and outer conversion arm 42.

[0047] like Figure 2 As shown, in the same principle as above, the second rivet shaft 13 provided on the base plate 1 is used so that the interruption arm 41 can always rotate around the second rivet shaft 13 relative to the base plate 1, thereby stably pushing the self-priming push rod 3 away from the lock tongue 2 to realize the interruption function of the self-priming action. Similarly, in order to realize the automatic reset of the interruption arm 41, this solution uses a second torsion spring 130 connected to the base plate 1 at one end and connected to the interruption link 43 at the other end. After the automatic reset of the internal and external conversion arm 42 is realized by the first torsion spring 110, the internal and external conversion arm 42 at this time no longer pushes the above-mentioned locking column 430, and then in the process of the elastic release of the second torsion spring 130, the interruption link 43 is pushed to automatically reset along the direction of the track groove 10, and finally drives the interruption arm 41 to reset to the initial position.

[0048] Preferably, the present solution further forms a mounting column 14 on the substrate 1 for mounting the first riveting shaft 11, such as Figure 4As shown, by arranging a third torsion spring 140 outside the mounting column 14, and utilizing the connecting portion 401 formed at the bottom of the outer opening arm 40, one end of the third torsion spring 140 is connected to the base plate 1, and the other end is movably connected to the connecting portion 401, so that the outer opening arm 40 can be driven to realize the automatic reset function under the elastic release of the third torsion spring 140. It is worth noting that, since the reset of the inner and outer conversion arm 42 and the outer opening arm 40 can be realized by relying on the first torsion spring 110, the double reset action of the third torsion spring 140 and the first torsion spring 110 further provides a guarantee for the stability of the automatic reset after the interruption of the self-suction action.

[0049] Preferably, if Figure 2 As shown, the interrupting link 43 of this solution is movably connected to the interrupting arm 41 through the interrupting arm rivet shaft 45, and the interrupting arm rivet shaft 45 is located at the periphery of the second rivet shaft 13, that is, the interrupting link 43 and the interrupting arm 41 are movably connected through the interrupting arm rivet shaft 45. The installation method of the interrupting arm rivet shaft 45 close to the second rivet shaft 13 can reduce the movement stroke required for the interrupting link 43 to push the interrupting arm 41 to rotate, indirectly saving the space required for the car lock in the vehicle space, and at the same time ensuring that the interrupting link 43 can smoothly push the interrupting arm 41 to realize the rotation function during the movement, effectively improving the stability of the mechanism during operation. A protective groove 402 is also formed at one end of the outer opening arm close to the outer opening pull wire. When the outer opening pull wire 5 is pulled to the outer opening arm to rotate a certain angle, the engaging column can just fall into the protective groove 402, which can limit the interrupting link from pushing the interrupting arm to rotate, thereby protecting the interrupting arm from damage when rotating.

[0050] The clutch arm 44 is also provided with a waist-shaped hole 442 movably mounted on the first rivet shaft 11 , and a locking link 12 connected to the motor is movably arranged on the base plate 1 , and the locking link 12 movably presses against the clutch arm 44 , so that the waist-shaped hole 442 on the clutch arm 44 can be displaced relative to the first rivet shaft 11 .

[0051] refer to Figures 2 to 4 The lock in this solution has an unlocked state and a locked state. When the clutch arm 44 is in Figure 2 and Figure 3 In the unlocked state shown in the figure, the outer opening arm 40 can be rotated to realize the function of the pusher 440 on the clutch arm 44 driving the inner and outer conversion arm 42 to rotate, and finally realize the interruption function of the self-closing action. Figure 3 When moving to the left, the locking link 12 can push the clutch arm 44 to move to the left synchronously (i.e., along the length direction of the waist-shaped hole 442), thereby realizing the movement of the waist-shaped hole 442 relative to the base plate 1 (i.e., the lock is in a locked state at this time), Figure 4 It can be seen from the structure shown that, since the outer opening arm 40 is designed in an S shape as a whole, there is no relative displacement between the outer opening arm 40 and the inner-outer conversion arm 42 in the original state, but the pushing part 440 and the driving part 400 are staggered with each other at this time, so that when the outer opening arm 40 rotates, it cannot apply the force of the clutch arm 44 to rotate, and can produce displacement relative to the inner-outer conversion arm 42 during the rotation of the outer opening arm 40, thereby realizing that the end of the outer opening arm 40 close to the outer opening wire 5 pushes the above-mentioned locking column 430 to move along the track groove 10, and finally realizes the self-closing action of interrupting the car door. It is also because of the design of the waist-shaped hole 442 and the locking link 12 that the structure can stably realize the self-closing interruption function of the car door when the lock is in different states.
