Description

Technical Field

[0001] The utility model belongs to the field of automobile door locks, and in particular relates to a multifunctional automobile door lock structure assembly. Background Art

[0002] With the continuous development and growth of the automobile industry, the position of the automobile industry in the development of the world economy has become more and more prominent. The automobile industry has a huge role and far-reaching impact on the development of the world economy and social progress; automobile door locks are an important component of the automobile body, and are a special component that integrates safety, decoration and craftsmanship.

[0003] Existing automobile door locks generally only have an inner opening interruption mechanism or an outer opening interruption mechanism. The interruption mechanism is a mechanism that quickly interrupts the self-closing action of the door through transmission between various components during the self-closing action of the door, so as to achieve an anti-pinch effect in an emergency situation. However, it is difficult to integrate both the inner opening and outer opening interruption mechanisms in the existing automobile door lock structure at the same time, and in the integrated automobile door lock structure, the installation of the locking pawl is often limited by the inner opening interruption mechanism and the outer opening interruption mechanism. Therefore, whether the door lock is in a locked state or an unlocked state, it is ultimately necessary to rely on the inner and outer conversion arms to push the interruption connecting rod to achieve the distance between the self-priming push rod and the lock tongue. Under the transmission of more components, not only the risk of component damage is increased, but also the output of a single component (i.e., the output of the inner and outer conversion arms) cannot effectively ensure the stable interruption function of the self-priming action.

[0049] 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.

[0050] like Figures 1 to 10 As shown, the utility model is a multifunctional automobile door lock structure assembly, including a self-priming push rod 10, a lock tongue 11 and a locking pawl 12 rotatably mounted on a housing 1, the self-priming push rod 10 is movably pressed against the lock tongue 11, so that the locking pawl 12 can lock the lock tongue 11 in a fully locked state, characterized in that: an outward opening self-priming interruption mechanism 2 and an inward opening self-priming interruption mechanism 3 are movably arranged in the housing 1, wherein the outward opening self-priming interruption mechanism 2 includes an interruption arm 20, an interruption connecting rod 21 and an outward opening arm 22, and the interruption arm 20 is movably arranged in the housing 1. The self-priming push rod 10 is pressed against the self-priming push rod 10; one end of the interrupting link 21 is movably connected to the interrupting arm 20, and the other end is movably pressed against the outer opening arm 22; the interrupting link 21 can be displaced relative to the housing 1 due to the rotation of the outer opening arm 22, so that when the interrupting arm 20 rotates, it can push the self-priming push rod 10 away from the lock tongue 11 to interrupt the self-priming action of the door; the inner opening self-priming interruption mechanism 3 includes an inner and outer conversion arm 30 and a clutch arm 31 rotatably mounted on the housing 1, and the inner and outer conversion arm 30, the clutch arm 31 and the outer opening arm 22 are coaxial with the rotation axis The inner and outer conversion arms 30 are centrally arranged, and when the inner and outer conversion arms 30 rotate, the interruption link 21 can be pushed to move, and the locking pawl 12 can unlock the lock tongue 11; the clutch arm 31 passes through the inner and outer conversion arms 30, so that one side wall of the clutch arm 31 movably abuts against the outer opening arm 22, and the other side wall abuts against the inner and outer conversion arms 30; a waist-shaped hole 310 is also formed on the clutch arm 31, and a locking link 13 is movably arranged in the housing 1, one side of the locking link 13 is movably connected to the inner opening self-absorbing interruption mechanism 3, and the other side movably abuts against the clutch arm 31, so that The locking link 13 can push the clutch arm 31 to displace relative to the inner and outer conversion arms 30 along the length direction of the waist-shaped hole 310, so that the door lock can realize the movable abutment and staggered placement between the clutch arm 31 and the outer opening arm 22 in the unlocked state and the locked state respectively; when the door lock is in the unlocked state, the clutch arm 31 can push the inner and outer conversion arms 30 to rotate due to the rotation of the outer opening arm 22; when the door lock is in the locked state, the outer opening arm 22 can directly push the interruption link 21 to move when rotating, so as to realize the interruption of the self-closing action of the car door.

[0051] like Figures 1 to 7 As shown, during the normal closing process of the door, the self-priming push rod 10 can gradually approach the lock tongue 11, and finally press the lock tongue 11 to the Figure 2 The fully locked state is shown. At the same time, the locking pawl 12 located on one side of the lock tongue 11 can limit the lock tongue 11 to the fully locked state to ensure the stability of the door when it is locked. This structure is the same as the locking principle in the prior art and will not be described in detail here.

[0052] This solution mainly realizes the interruption function of the door lock's internal and external opening self-closing action in the unlocked state and the locked state. Specifically, when the door is self-closing and the door lock is in the unlocked state, the clutch arm 31 abuts against the external opening arm 22 and the internal and external conversion arm 30 respectively. Figure 4 When rotating in the counterclockwise direction, the clutch arm 31 can be pushed to rotate synchronously, so that the inner and outer conversion arm 30 can push the interruption link 21 along the rotation direction. Figure 4 That is to say, by changing the original movement trajectory of the self-priming push rod 10, the self-priming push rod 10 can no longer exert the force to rotate the lock tongue 11 to reach a fully locked state, thereby preventing pinching in an emergency.

[0053] Further, when the locking link 13 is Figure 4 When the clutch arm 31 is pushed to the left, the door lock is switched to the locked state, and the clutch arm 31 no longer abuts against the outer opening arm 22, so when the outer opening arm 22 moves along the Figure 4 When rotating in the counterclockwise direction, the clutch arm 31 and the inner and outer conversion arm 30 cannot continue to rotate synchronously, but directly interrupt the connecting rod 21 along the Figure 4 Similarly, with the driving of the inner opening self-suction interruption mechanism 3, whether the door lock is in a locked state or an unlocked state, the inner opening self-suction interruption function can be realized by directly driving the interruption link 21 to move through the force of the rotation of the inner and outer conversion arms 30, and at the same time, the locking pawl 12 can be pushed away from the lock tongue 11 to achieve the state of the door opening, which provides a double guarantee for realizing the anti-pinch function both outside and inside the vehicle in an emergency. It can be seen that by integrating the installation design of the inner opening arm 45, the clutch arm 31 and the outer opening arm 22, it not only saves the space occupied by the components, but also can use the tight contact mode between the three to cooperate with the waist-shaped hole 310, so that the door lock can realize the interruption of the self-suction action through different components in different states, which not only effectively avoids the risk of component damage, but also provides a guarantee for the stable interruption function of the self-suction action, and prolongs the service life of the automobile door lock; at the same time, combined with the inner opening self-suction interruption mechanism 3 to drive the rotation output of the inner opening arm 45, the locking pawl 12 is no longer restricted by the installation position, which improves the flexibility of installation.

[0054] A U-shaped groove 300 is formed on the inner and outer conversion arm 30, and a pushing portion 220 flush with one side wall of the U-shaped groove 300 is formed at the end of the outer opening arm 22. A receiving portion 311 is formed at the bottom of the clutch arm 31, and the receiving portion 311 passes through the U-shaped groove 300, so that one side of the receiving portion 311 is simultaneously pressed against the pushing portion 220 and one side wall of the U-shaped groove 300, and the other side is pressed against the other side wall of the U-shaped groove 300.

[0055] like Figure 4 and Figure 6 As shown, for the integrated installation method between the inner and outer conversion arm 30, the clutch arm 31 and the outer opening arm 22, the solution is provided with a U-shaped groove 300 on the inner and outer conversion arm 30. In the initial installation state, the outer opening arm 22, the inner and outer conversion arm 30 and the clutch arm 31 are in Figure 5 The U-shaped groove 300 is installed on the shell 1 from bottom to top. At the same time, one side of the U-shaped groove 300 is flush with the end of the pushing portion 220, and the other side is pressed against the receiving portion 311 of the clutch arm 31. 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. On the other hand, it is beneficial for the outer opening arm 22 to rotate. Through the close contact between the structures, it can ensure that the clutch arm 31 and the inner and outer conversion arm 30 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.

[0056] A track groove 14 is formed on the shell 1, and the end of the interrupting link 21 away from the interrupting arm 20 is connected to a guide rivet shaft 210. The inner and outer conversion arms 30 and the outer opening arm 22 are both movably pressed against the guide rivet shaft 210, and the guide rivet shaft 210 is movably engaged in the track groove 14 to guide the interrupting link 21 to push the interrupting arm 20 to rotate.

[0057] like Figure 4 and Figure 6 As shown, when the above-mentioned inner and outer conversion arm 30 pushes the interrupt link 21 to move during the rotation process, the active engagement between the guide rivet shaft 210 and the track groove 14 can be relied upon to guide and limit the movement of the interrupt link 21, thereby ensuring the smoothness and stability of the interrupt link 21 when pushing the interrupt arm 20 to rotate, thereby effectively ensuring that the interrupt arm 20 pushes the self-priming push rod 10 away from the lock tongue 11 during the rotation process to achieve a stable interruption effect of the self-priming action.

[0058] Preferably, the present solution further forms a protective groove 223 at one end of the outer opening arm 22 near the outer opening pull wire. When the outer opening pull wire is pulled to the outer opening arm 22 and rotated to a certain angle, the guide rivet shaft 210 can just fall into the protective groove 223. At this time, it can limit the interrupting link from pushing the interrupting arm to rotate, thereby protecting the interrupting arm from damage during rotation.

[0059] A clearance groove 221 is also formed between the pushing portion 220 and the outer opening arm 22. When the door lock is in a locked state, the receiving portion 311 can move along the U-shaped groove 300 to the open end of the clearance groove 221, so that the inner and outer conversion arm 30 does not rotate with the rotation of the outer opening arm 22.

[0060] It is worth noting that when the door lock is Figure 4 In the unlocked state shown in the figure, the receiving portion 311 at this time abuts against the inner wall of the pushing portion 220 and the U-shaped groove 300 respectively, so as to ensure that the outer opening arm 22 can instantly drive the clutch arm 31 and the inner and outer conversion arm 30 to rotate synchronously when rotating, effectively avoiding the generation of a rotation gap between the three and affecting the smoothness and stability of the self-suction interruption action; and when the locking link 13 pushes the clutch arm 31 along Figure 4 When moving to the left, the door lock can be switched to a locked state, so that the receiving portion 311 and the pushing portion 220 are placed alternately. In this way, as the outer opening arm 22 rotates, the giving way groove 221 is gradually sleeved on the receiving portion 311, and no rotational force is applied to the clutch arm 31 and the inner-outer conversion arm 30. Instead, the interruption link 21 is directly pushed to move during the rotation of the outer opening arm 22 to realize a self-suction interruption action. This structure can not only ensure that the door locks in different states can realize the self-suction interruption function, but also effectively avoid the inner-outer conversion arm 30 or the outer opening arm 22 from outputting a single rotational torque when the door lock is in a locked or unlocked state, thereby preventing damage to components due to frequent operation and extending the service life of the car door lock.

[0061] The outward opening self-closing interruption mechanism 2 also includes: an outward opening pull wire 23, which is arranged in the shell body 1, one end of the outward opening pull wire 23 extends out of the shell body 1 and is connected to the vehicle door, and the other end is connected to the end of the outward opening arm 22 away from the pushing portion 220; an installation rivet shaft 24, which is arranged in the shell body 1, and the outward opening arm 22, the inner and outer conversion arm 30 and the clutch arm 31 are rotatably connected to the installation rivet shaft 24 in sequence, and when the locking link 13 pushes the clutch arm 31 to move, the installation rivet shaft 24 can move relatively in the waist-shaped hole 310; a first torsion spring 240a and a second torsion spring 312a, the installation rivet shaft 24 and the clutch arm 31 are respectively formed with a first connecting column 240 and a second connecting column 312, a connecting block 211 is formed on the interruption link 21, and the first torsion spring 240a is arranged on the first connecting column 240 and one end is connected to the clutch arm 310. They are connected, and the other end is connected to the connecting block 211; the second torsion spring 312a is arranged on the second connecting column 312 and one end is connected thereto, and the other end of the second torsion spring 312a is connected to the second connecting column 312; the third torsion spring 150, the shell 1 is also provided with a mounting column 15 for fixing the mounting rivet shaft 24, and an extension block 222 is formed on the outer opening arm 22, the third torsion spring 150 is arranged on the mounting column 15, and one end is connected to the shell 1, and the other end is connected to the extension block 222; the fixed rivet shaft 16 is arranged on the shell 1, the interrupting arm 20 is rotatably connected to the fixed rivet shaft 16, and a connecting part 200 is formed on the interrupting arm 20, and a fourth torsion spring 160 is arranged on the fixed rivet shaft 16, one end of the fourth torsion spring 160 is connected to the shell 1, and the other end is connected to the connecting part 200.

[0062] When the car door is in the self-priming process (that is, the self-priming push rod 10 is in the initial position at this time and has not yet abutted against the lock tongue 11), you only need to pull the outer opening pull wire to drive the outer opening arm 22 to rotate. The structure is simple and the operation is convenient and quick. In order to facilitate the installation of the inner and outer conversion arms 30, the outer opening arm 22 and the clutch arm 31, the present scheme is provided with an installation rivet shaft 24 on the shell 1. The installation rivet shaft 24 is used to realize that the above-mentioned components all rotate around it, ensuring the smoothness and stability of each component during the connection and rotation steps. At the same time, the first torsion spring 240a and the second torsion spring 312a are respectively installed on the first connecting column 240 and the second connecting column 312, so that after the above-mentioned interruption self-priming action is completed, it is effectively guaranteed that the interruption connecting rod 21 and the clutch arm 31 can be reset to the initial position for the normal use of the subsequent self-priming interruption action. It is worth noting that since the receiving portion 311 on the clutch arm 31 passes through the U-shaped groove 300 of the internal and external conversion arm 30 and movably abuts against the pushing portion 220 on the external opening arm 22, during the resetting process of the clutch arm 31 through the above-mentioned second torsion spring 312a, it can also push the internal and external conversion arm 30 and the external opening arm 22 to realize the resetting function, effectively reducing the number of torsion springs used and saving the space occupied by the door lock.

[0063] Preferably, the present solution further forms a mounting column 15 on the housing 1 for fixing and mounting the riveting shaft 24, such as Figure 5 As shown, by arranging a third torsion spring 150 outside the mounting column 15, and utilizing the extension block 222 formed at the bottom of the outer opening arm 22, one end of the third torsion spring 150 is connected to the housing 1, and the other end is movably connected to the extension block 222, so that the outer opening arm 22 can be driven to realize the automatic reset function under the elastic release of the third torsion spring 150. It is worth noting that, since the reset of the inner-outer conversion arm 30 and the outer opening arm 22 can be realized by relying on the second torsion spring 312a, the dual reset action of the third torsion spring 150 and the second torsion spring 312a further provides a guarantee for the stability of each component when automatically resetting after the interruption of the self-suction action is completed.

[0064] like Figure 4 As shown, in the same principle as above, the fixed rivet shaft 16 provided on the housing 1 is used so that the interruption arm 20 can always rotate around the fixed rivet shaft 16 relative to the housing 1, thereby stably pushing the self-priming push rod 10 away from the lock tongue 11 to realize the interruption function of the self-priming action. Similarly, in order to realize the automatic reset of the interruption arm 20, this solution uses a fourth torsion spring 160 connected to the housing 1 at one end and connected to the interruption link 21 at the other end. After the automatic reset of the internal and external conversion arm 30 is realized under the cooperation of the first torsion spring 240a and the second torsion spring 312a, the internal and external conversion arm 30 no longer pushes the guide rivet shaft 210, and then in the process of the elastic release of the fourth torsion spring 160, the interruption link 21 is pushed along Figure 4 The track groove 14 shown moves rightward to automatically reset, and finally drives the interruption arm 20 to reset to the initial position.

[0065] The inner opening self-closing interruption mechanism 3 also includes: a driving member 32 and a worm wheel 34, which are arranged in the housing 1, and the driving end of the driving member 32 is coaxially connected to the worm 33; the worm wheel 34 is rotatably arranged in the housing 1 and is movably engaged with the worm 33; an electric release swing arm 35, which is rotatably arranged in the housing 1, and the electric release swing arm 35 is formed with an active arm 350 and a driven arm 351 arranged at an angle, and a cam 340 is formed on the worm wheel 34, and the cam 340 can be movably pressed against the active arm 350 when the worm wheel 34 rotates; a first protrusion 351a and a second protrusion 351a are formed on the driven arm 351 351b, the side of the locking pawl 12 facing away from the shell 1 is coaxially connected with a rotating block 120 and a release arm 121, the rotating block 120 is connected to the locking pawl 12, and the first protrusion 351a movably abuts against the rotating block 120 to drive the locking pawl 12 to disengage from the lock tongue 11; the end of the inner and outer conversion arm 30 away from the interrupt link 21 is formed with a bending portion 301, and the end of the release arm 121 is pressed against the bending portion 301, so that when the second protrusion 351b pushes the release arm 121 to rotate, it can drive the inner and outer conversion arm 30 to rotate and push the interrupt link 21 to move relative to the shell 1.

[0066] like Figure 6 to Figure 7 As shown, when the inner opening self-closing action needs to be interrupted, when the driving member 32 rotates forward to drive the worm 33 to rotate, the worm wheel 34 can be driven to rotate and drive the electric release swing arm 35 along the Figure 7 The locking pawl 12 rotates counterclockwise, thereby pushing the release arm 121 coaxially arranged on the side away from the housing 1 to rotate, and finally, under the bent portion 301 of the inner-outer conversion arm 30, the force of the interruption connecting rod 21 is applied during the rotation of the inner-outer conversion arm 30, and finally, when the interruption arm 20 pushes the self-priming push rod 10 away from the lock tongue 11, the interruption function of the inner opening self-priming action is completed. In this process, since the worm gear 34 and the release arm 121 are not on the same plane of the housing 1, the movable abutment between the cam 340 and the active arm 350 effectively avoids the large instantaneous rotation torque applied by the worm gear 34, which causes the electric release swing arm 35 to drive the release arm 121 to cause a jam or misalignment phenomenon, and effectively improves the smoothness and stability of the driven arm 351 when pushing the release arm 121 to rotate.

[0067] Furthermore, in order to ensure that the locking pawl 12 can unlock the lock tongue 11 when the inner opening self-closing is interrupted, the locking pawl 12 is connected to the rotating block 120. As the cam 340 applies the rotational force of the active arm 350, the first protrusion 351a on the driven arm 351 pushes the rotating block 120, and the second protrusion 351b can be used to push the release arm 121 to rotate. In other words, the structure can realize the interruption of the inner opening self-closing action under the unified rotation of the driven arm 351, and can also realize the unlocking of the lock tongue 11 by the locking pawl 12. The two action processes do not interfere with each other, and effectively ensure that the car door can smoothly switch to a half-open or fully open state after the self-closing action is interrupted. It is also because of the design of this structure, combined with the waist-shaped hole 310 on the clutch arm 31, that the installation position of the locking pawl 12 is no longer restricted by the inner and outer conversion arm 30, and the installation flexibility is high, while ensuring the smooth realization of the inner and outer opening self-closing interruption function.

[0068] A locking arm 17 is also rotatably provided on the housing 1, and a first engaging block 170 and a second engaging block 171 are formed on the locking arm 17 and are arranged at an angle. A driving groove 341 is formed on the side wall of the worm gear 34, and an engaging groove 130 is formed in the locking link 13. The first engaging block 170 is movably engaged in the driving groove 341, and the second engaging block 171 is movably engaged in the engaging groove 130, so that when the worm gear 34 rotates, the locking link 13 can be pushed to move in the housing 1 through the locking arm 17.

[0069] like Figure 4 and Figure 6As shown, the width of the driving groove 341 is greater than the width of the first engaging block 170. That is to say, as the driving member 32 is turned on and drives the worm wheel 34 to rotate, when the inner wall of one side of the driving groove 341 is close to the first engaging block 170, the locking arm 17 can be driven along the Figure 4 The locking link 13 is rotated clockwise, and the second engaging block 171 cooperates with the engaging groove 130 to finally drive the locking link 13 to rotate along the Figure 4 Move straight to the left, thereby pushing the clutch arm 31 against which it moves. Figure 4 The waist-shaped hole 310 is synchronously displaced to the left (i.e., along the length direction of the waist-shaped hole 310), thereby realizing the movement of the waist-shaped hole 310 relative to the installation rivet shaft 24 (i.e., the door lock is in a locked state at this time), Figure 4 It can be seen from the structure shown that, due to the overall S-shaped design of the outer opening arm 22, there is no relative displacement between the outer opening arm 22 and the inner and outer conversion arm 30 in the original state, but the pushing part 2204 and the driving part are staggered, so that when the outer opening arm 22 rotates, it cannot apply the force of the clutch arm 31 to rotate, and during the rotation of the outer opening arm 22, it can produce a rotational displacement relative to the inner and outer conversion arm 30, thereby pushing the above-mentioned guide rivet shaft 210 to move along the track groove 14, and finally realizing the self-suction action of interrupting the door. It is also because of the design of the waist-shaped hole 310 and the locking link 13 that the structure can stably realize the self-suction interruption function of the door when the door lock is in different states.

[0070] Preferably, if Figure 4 As shown, the interrupt link 21 and the interrupt arm 20 of the present solution are movably connected via the interrupt arm rivet shaft 36, and the interrupt arm rivet shaft 36 is located at the periphery of the fixed rivet shaft 16, that is, the active connection between the interrupt link 21 and the interrupt arm 20 is realized by the interrupt arm rivet shaft 36, and the installation method of the interrupt arm rivet shaft 36 close to the fixed rivet shaft 16 can reduce the moving stroke required for the interrupt link 21 to push the interrupt arm 20 to rotate, indirectly saving the space required for the car lock in the vehicle space, and also ensuring that the interrupt link 21 can smoothly push the interrupt arm 20 to realize the rotation function during the movement, effectively improving the stability of the mechanism during operation.

[0071] Preferably, the present solution also has a self-priming push rod rivet shaft 100 connected to the self-priming push rod 10, and an arc-shaped raised surface 201 is formed on the interrupting arm 20. The arc-shaped raised surface 201 is movably pressed against the self-priming push rod rivet shaft 100, thereby ensuring that the interrupting arm 20 can smoothly push the self-priming push rod 10 away from the lock tongue 11 during the rotation process, thereby further improving the accuracy and stability of the interruption of the self-priming action process of the car door.

[0072] The present scheme also includes: a driving motor 40 and an arc gear 41, which are arranged in the shell 1, and the driving end of the driving motor 40 is coaxially connected with a transmission rod 42, and the transmission rod 42 is movably meshed with the arc gear 41; a swing arm 43 and an inner clutch arm 44, which are arranged in the shell 1, and the swing arm 43 is connected to the arc gear 41, and a traction groove 430 is provided on the swing arm 43, one end of the inner clutch arm 44 is movably engaged with the traction groove 430, and the other end is movably abutted against the electric release swing arm 35; an inner opening arm 45 connected to the inner opening pull wire, the inner opening arm 45 and the electric release swing arm 35 are arranged with the same rotation axis, and a guide groove 450 is formed on the inner opening arm 45, and the inner clutch arm 44 is movably engaged with the guide groove 450, and can be switched between the unlocking position and the locking position of the guide groove 450.

[0073] In order to ensure the safety of children when riding in a car, the present solution also combines a child lock structure in the car door lock, specifically, Figure 3 , Figures 8 to 10 As shown, when the driving motor 40 is turned on and drives the coaxially connected worm 33 transmission rod 42 (i.e., the worm 33 structure) to rotate, the transmission rod 42 can drive the arc gear 41 that is movably meshed with it to rotate during the rotation process, thereby Figure 3 The swing arm 43 is shown to move to Figure 8 At the position shown, the inner opening clutch arm 44 connected to the end of the swing arm 43 is finally moved from the unlocking position relative to the inner opening arm 45 to Figure 8 In the locked position shown, it should be noted that when the inner clutch arm 44 is in Figure 3 When the electric release swing arm 35 is in the position shown, the inner opening pull wire can be pulled to drive the inner opening arm 45 and the inner opening clutch arm 44 to move synchronously around the rotation axis of the electric release swing arm 35. Figure 3 When the inner opening clutch arm 44 rotates counterclockwise, the inner opening clutch arm 44 can push the electric release swing arm 35 to rotate, and the above inner opening self-suction interruption action is repeated to realize the normal opening of the door; Figure 8 When the user pulls the door handle again, the inner opening arm 45 will still drive the inner opening clutch arm 44 along the Figure 3 The inner clutch arm 44 rotates counterclockwise, but at this time, the inner clutch arm 44 is in an idling state (that is, the inner clutch arm 44 is at the periphery of the electric release swing arm, and the two cannot contact each other during rotation). If the rotation force of the electric release swing arm 35 cannot be applied, the door opening function cannot be realized. The overall structure is relatively simple, which reduces the use of parts and effectively ensures the smoothness and stability of the inner clutch arm 44 when switching between the unlocking position and the locking position. At the same time, the structure utilizes the self-locking characteristics of the arc gear 41 and the transmission rod 42 to provide a guarantee for the stability of the inner clutch arm 44 when it is in the unlocking position and the locking position.

[0074] An arc-shaped guide portion 352 is formed by protruding outward at the periphery of the electric release swing arm 35, and an extension portion 440 and a snap portion 441 are formed at the end of the inner opening clutch arm 44, and the snap directions of the extension portion 440 and the snap portion 441 are opposite, and the extension portion 440 can press against the bottom wall of the inner opening arm 45 while making the snap portion 441 press against the top wall of the inner opening and movably press against the arc-shaped guide portion 352.

[0075] Preferably, if Figures 8 to 10 As shown, the buckle portion 441 in the present scheme consists of a guide portion 441a and an anti-slip portion 441b, wherein the guide portion 441a can pass through the above-mentioned traction groove 430 or the guide groove 450, so that the anti-slip portion 441b located at the end of the guide portion 441a can be pressed against the outer wall of the inner opening arm 45 or the swing arm 43, effectively avoiding the inner opening clutch arm 44 from getting stuck when it rotates with the inner opening arm 45, ensuring that the inner opening clutch arm 44 in the unlocked position can smoothly push the electric release swing arm 35 through the buckle portion 441 to realize the door opening function, in addition, the guide portion 441a guides and limits the movement of the inner opening clutch arm 44, and at the same time can use the anti-slip portion 441b to effectively avoid the inner opening clutch arm 44 from falling off during the movement, thereby improving the stability of the structure during operation.

[0076] Further, if Figures 8 to 10 As shown, the snap portion 441 of the inner opening clutch arm 44 in the unlocked position is located at the end of the arc-shaped guide portion 352. Since the electric release swing arm 35 and the inner opening arm 45 are arranged with the same rotation axis, the extension portion 440 at the end of the inner opening clutch arm 44 is used to cooperate with the anti-detachment portion 441b of the snap portion 441, which effectively ensures the stability of the snap portion 441 and the inner opening arm 45 when they are movably engaged. It should be noted that the extension portion 440 and the anti-slip portion 441b are oriented in opposite directions, and are distributed on both sides of the length direction of the guide groove 450 during the clamping process, which has a certain limiting effect. At this time, the guide portion 441a also happens to be movable and pressed against the end of the arc-shaped guide portion 352, ensuring the stability of the arc-shaped guide portion 352 when the inner-opening clutch arm 44 rotates and pushes the arc-shaped guide portion 352 to rotate synchronously. The design of the guide portion 441a being movable and pressed against the raised arc-shaped guide portion 352 also effectively avoids the stability of the inner-opening device being affected when the electric release swing arm 35 drives the transmission.

[0077] like Fig.10As shown, with respect to the connection between the arc gear 41 and the swing arm 43, an extension plate 410 is formed on the arc gear 41 in the present solution, and a positioning block 410a and a limit block 410b connected to each other are provided on the extension plate 410, and a positioning hole 431 and a limit hole 432 connected to each other are formed at the end of the swing arm 43 away from the inner clutch arm 44. During the installation process, the worker can align the positioning block 410a with the positioning hole 431. Similarly, after the limit hole 432 and the limit block 410b are aligned and placed, the positioning block 410a can be extended into the positioning hole 431, and the limit block 410b can also be extended into the limit hole 432 at this time, so as to realize the positioning installation of the swing arm 43 and the arc gear 41, effectively ensure the stability between the swing arm 43 and the arc gear 41, and provide a guarantee for the accuracy and stability of the inner clutch arm 44 when switching between the unlocking position and the locking position. It should be added that when the above-mentioned arc gear 41 and the swing arm 43 are movably connected, the present solution can utilize the limiting structure (not shown in the figure) inside the shell 1 to ensure the stability of the two after the connection, thus achieving a certain limiting effect.

[0078] It should be noted that the driving member 32 in the present embodiment can be replaced by other driving devices such as a stepping motor and a servo motor, and for the resetting of the above-mentioned swing arm 43, the inner clutch arm 44 and the inner opening arm 45, the automatic and accurate resetting function can also be achieved by installing a torsion spring. The working principle is the same as above and will not be described in detail here.

[0079] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0081] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
