[0030] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0031] FIG1 is a schematic diagram of the structure of a vehicle door lock in one embodiment of the present application. FIG2 is a schematic diagram of the exploded perspective structure of the vehicle door lock in FIG1 . As shown in FIG1 and FIG2 , the present application provides a vehicle, comprising a vehicle door and a vehicle door lock 100, wherein the vehicle door lock 100 is mounted on the vehicle door and fastened to the vehicle door by bolts. The vehicle door lock 100 provided in an embodiment of the present application is applied to a vehicle, which may specifically be a fuel-powered vehicle or a new energy electric vehicle, and the vehicle door lock 100 can help the vehicle realize the functions of opening and locking the vehicle door.

[0032] The vehicle door lock 100 includes a connecting rod structure 11, a push rod 12, a locking arm, and a locking tongue. The connecting rod structure 11 pulls the push rod 12, which abuts the locking arm, which then engages the locking tongue. The connecting rod structure 11 has an unlocked position and a locked position. A user can switch the connecting rod structure 11 to the unlocked position or the locked position using a vehicle key, a remote control, or other suitable means. When the connecting rod structure 11 switches from the unlocked position to the locked position, the connecting rod structure 11 pulls the push rod 12 to move, releasing the abutment between the push rod 12 and the locking arm, and the locking arm engages the locking tongue. At this point, the user cannot open the vehicle door by actuating the inner or outer handle. When the connecting rod structure 11 switches from the locked position to the unlocked position, the connecting rod structure 11 pulls the push rod 12 in the opposite direction, abutting the locking arm, releasing the abutment between the locking arm and the locking tongue, and the user can open the vehicle door by actuating the inner or outer handle.

[0033] The vehicle door lock 100 also includes an outward opening rocker and a mating rocker arm 14. The outward opening rocker is connected to the vehicle's outward opening handle and is connected to the mating rocker arm 14 via a pin. When the linkage structure 11 is in the unlocked position, the user activates the outward opening handle, which rotates the outward opening rocker, which in turn rotates the mating rocker arm 14. The mating rocker arm 14 switches from a locked state to an unlocked state, and the mating rocker arm 14 rotates the push rod 12, which abuts the locking arm, releasing the locking arm and the lock tongue, and the vehicle door opens.

[0034] The vehicle door lock 100 further includes an inner opening rocker 35, a first rocker arm 21, a connecting arm 32, and a sliding member 31. The inner opening rocker 35 is connected to the vehicle's inner opening handle and abuts the first rocker arm 21. The first rocker arm 21 abuts the connecting arm 32 via the sliding member 31, and the connecting arm 32 abuts the inner opening rocker 35. When the connecting rod structure 11 is in the unlocked position, if the user actuates the inner opening handle, the inner opening rocker 35 rotates, which in turn drives the first rocker arm 21 to rotate. The first rocker arm 21 drives the connecting arm 32 to rotate via the sliding member 31. The connecting arm 32 rotates the mating rocker arm 14, switching the mating rocker arm 14 from a locked state to an unlocked state. The mating rocker arm 14 then rotates the push rod 12, which abuts the locking arm, releasing the engagement between the locking arm and the deadbolt, and the vehicle door opens.

[0035] For details, please refer to Figures 3 and 4 . Figure 3 is a partially enlarged view of the vehicle door lock in Figure 1 from another perspective, and Figure 4 is a schematic three-dimensional structural diagram of the first rocker arm of the vehicle door lock in Figure 1 . As shown in Figures 3 and 4 , the first rocker arm 21, the connecting arm 32, and the sliding member 31 are stacked in sequence, with the first rocker arm 21 and the connecting arm 32 connected by the sliding member 31. The first rocker arm 21 is provided with a first drive groove 211 and a first clearance groove 212. The connecting post 312 can be inserted into the first drive groove 211 and the first clearance groove 212. The first drive groove 211 and the first clearance groove 212 extend through the first rocker arm 21 and are connected to each other. The first drive groove 211 and the first clearance groove 212 are arranged in an L-shape, with the first drive groove 211 positioned above the first clearance groove 212. Of course, the first drive groove 211 can also be positioned below the first clearance groove 212, without limitation. The first drive groove 211 and the first escape groove 212 have a smooth transition at their interface, facilitating the smooth sliding of the connecting post 312 between the first drive groove 211 and the first escape groove 212. In other examples, the first drive groove 211 and the first escape groove 212 are formed on the surface of the first rocker arm 21 facing the connecting arm 32, and the first drive groove 211 and the first escape groove 212 do not penetrate the first rocker arm 21. This also allows the connecting post 312 to slide and connect with the first rocker arm 21.

[0036] The connecting arm 32 is provided with a first waist-shaped hole 321, which passes through the connecting arm 32. The first driving groove 211 and at least part of the first clearance groove 212 are aligned with the first waist-shaped hole 321. The connecting post 312 is inserted into the first waist-shaped hole 321 and can move along the long axis of the first waist-shaped hole 321.

[0037] The sliding member 31 includes a connecting piece 311 and a connecting column 312 connected to the connecting piece 311. The connecting piece 311 has a sheet-like structure, and the connecting column 312 has a columnar structure. The connecting column 312 is connected to a side wall of the connecting piece 311 facing the connecting arm 32 along the thickness direction of the connecting piece 311. The connecting column 312 is passed through the first driving groove 211 (or the first avoidance groove 212) of the first rocker arm 21 and the first waist-shaped hole 321 of the connecting arm 32.

[0038] When the connecting column 312 is passed through the first driving groove 211 and the first waist-shaped hole 321, the first rocker arm 21 is driven to rotate. The first rocker arm 21 is fixedly connected to the connecting arm 32 through the connecting column 312. The first rocker arm 21 drives the connecting arm 32 to rotate. The connecting arm 32 abuts against the rotating rocker arm 14. The rocker arm 14 switches from a locked state to an unlocked state. The rocker arm 14 abuts against the push rod 12 to rotate. The push rod 12 abuts against the locking arm to rotate, so that the lock tongue disengages from the locking arm and the car door is unlocked.

[0039] When the connecting column 312 passes through the first avoidance groove 212 and the first waist-shaped hole 321, the first rocker arm 21 is driven to rotate, the first rocker arm 21 and the connecting arm 32 are released from the fixed connection, the first rocker arm 21 and the connecting arm 32 move independently, the connecting arm 32 does not rotate relative to the first rocker arm 21, the cooperating rocker arm 14 remains in a locked state, the cooperating rocker arm 14 does not rotate, and the vehicle door remains locked.

[0040] In some embodiments, referring to Figures 1 and 2 , the vehicle door lock 100 further comprises a toggle 34 , which is a sheet-like structure and is disposed on a side of the slider 31 away from the connecting arm 32 . The toggle 34 is slidably and rotationally connected to the slider 31 , and the toggle 34 drives the slider 31 to move, thereby moving the connecting post 312 to the first driving slot 211 or the first escape slot 212 .

[0041] Specifically, one of the sliding member 31 and the dial knob 34 is provided with a sliding groove 313, and the other is provided with a sliding post 341. The sliding post 341 is disposed through the sliding groove 313 and is capable of sliding within the sliding groove 313. The dial knob 34 drives the sliding member 31 to move, so that the connecting post 312 of the sliding member 31 moves to the first driving groove 211 or the first avoiding groove 212. In this example, the sliding groove 313 is opened in the sliding member 31 and passes through the sliding member 31. The sliding post 341 is provided on the dial knob 34. The sliding post 341 is disposed through the sliding groove 313 and is capable of sliding within the sliding groove 313. The sliding post 341 drives the sliding member 31 to move, so that the connecting post 312 of the sliding member 31 moves to the first driving groove 211 or the first avoiding groove 212. The sliding groove 313 can also be formed on the surface of the sliding member 31 facing the toggle knob 34. The sliding groove 313 does not pass through the sliding member 31. Alternatively, the sliding post 341 can be inserted into the sliding groove 313 and slide within the sliding groove 313. In other embodiments, the sliding groove 313 can be formed on the sliding member 31 or pass through the sliding member 31 to achieve the same effect.

[0042] The vehicle door lock 100 provided herein can also be used as a child lock for the rear door. When the user toggles the dial 34, the dial 34 drives the slider 31 to move, causing the connecting post 312 to move to the first clearance slot 212, thereby activating the child lock. When the connecting post 312 moves to the first drive slot 211, the child lock is deactivated.

[0043] When the child lock is enabled, the user drives the inner opening handle to rotate, and the inner opening handle drives the inner opening rocker 35 to rotate. The inner opening rocker 35 abuts the first rocker arm 21 and drives the first rocker arm 21 to rotate. The movements of the first rocker arm 21 and the connecting arm 32 are relatively independent. The connecting arm 32 does not rotate relative to the first rocker arm 21, and the matching rocker arm 14 does not rotate. The matching rocker arm 14 remains in a locked state, and the user cannot open the car door by driving the inner opening handle.

[0044] When the child lock is closed, the user rotates the inner opening handle, which in turn rotates the inner opening rocker 35. The inner opening rocker 35 abuts the first rocker arm 21, driving the first rocker arm 21 to rotate. The first rocker arm 21, via the connecting post 312 of the slider 31, drives the connecting arm 32 to rotate. The connecting arm 32 abuts the mating rocker arm 14, switching the mating rocker arm 14 from locked to unlocked, and the door opens. While the vehicle is in motion, the child lock prevents passengers from accidentally opening the door, protecting their safety.

[0045] Figure 5 is a schematic exploded perspective view of the vehicle door lock according to an embodiment of the present application. In some embodiments, as shown in Figures 2 and 5 , the vehicle door lock 100 further includes a second rocker arm 22, a locking pin 23, and a locking link 24. The second rocker arm 22 is disposed on a side of the first rocker arm 21 away from the connecting arm 32, and the locking pin 23 is rotatably and slidably connected between the first rocker arm 21 and the second rocker arm 22.

[0046] The first rocker arm 21 also includes a second drive slot 214 and a second escape slot 215. The second drive slot 214 and the second escape slot 215 are spaced apart from the first drive slot 211 and the first escape slot 212. The first locking portion 231 of the locking pin 23 can be inserted into the second drive slot 214 and the second escape slot 215. The second drive slot 214 and the second escape slot 215 extend through the first rocker arm 21 and are interconnected. The second drive slot 214 and the second escape slot 215 are arranged in an L-shape, with the second drive slot 214 positioned below the second drive slot 214. Alternatively, the second drive slot 214 can be positioned above the second drive slot 214, without limitation. The edges of the second drive slot 214 and the second escape slot 215 are smoothly connected, facilitating smooth sliding of the first locking portion 231 between the second drive slot 214 and the second escape slot 215. In other examples, the second drive groove 214 and the second avoidance groove 215 are opened on the side wall of the first rocker arm 21 facing the second rocker arm 22. The second drive groove 214 and the second avoidance groove 215 do not pass through the first rocker arm 21, and the locking pin 23 can also be slidably connected to the first rocker arm 21.

[0047] The second rocker arm 22 is provided with a second waist-shaped hole 221 , which passes through the second rocker arm 22 . The second locking portion 232 of the locking pin 23 can be passed through the second waist-shaped hole 221 , and the locking pin 23 can move along the long axis of the second waist-shaped hole 221 .

[0048] The locking pin 23 includes a first locking portion 231 and a second locking portion 232 disposed at opposite ends thereof, and a connecting portion 234 connected between the first locking portion 231 and the second locking portion 232. The first locking portion 231, the second locking portion 232, and the connecting portion 234 are integrally formed. The connecting portion 234 is clamped between the first rocker arm 21 and the second rocker arm 22. The first locking portion 231, the second locking portion 232, and the connecting portion 234 are cylindrical in shape. The radial dimension of the connecting portion 234 is greater than the radial dimension of the first locking portion 231 and the second locking portion 232. The locking pin 23 can slide in a direction perpendicular to the thickness of the first rocker arm 21 and the second rocker arm 22, but cannot move in the thickness direction of the first rocker arm 21 and the second rocker arm 22.

[0049] The locking link 24 includes a first link 241 and a second link 242. The first link 241 and the second link 242 are fixedly connected. The first link 241 is used to abut against the second rocker arm 22. The second link 242 is provided with a connecting groove 240. The connecting rod structure 11 is passed through the connecting groove 240. The second link 242 is used to drive the connecting rod structure 11 to rotate so as to switch the connecting rod structure 11 to an unlocked position or a locked position.

[0050] When the first locking portion 231 of the locking pin 23 is inserted into the second driving slot 214, the first rocker arm 21 and the second rocker arm 22 are fixedly connected. The first rocker arm 21 drives the second rocker arm 22 to rotate via the locking pin 23. The second rocker arm 22 abuts against the first link 241 of the locking link 24, and the locking link 24 is rotated, and the locking link 24 is in the unlocked position. The first rocker arm 21 is then driven again, which drives the connecting arm 32 to rotate. The connecting arm 32 abuts against the mating rocker arm 14, driving the mating rocker arm 14 to rotate, and the door opens.

[0051] When the first locking portion 231 of the locking pin 23 is inserted into the second clearance groove 215, the fixed connection between the first rocker arm 21 and the second rocker arm 22 is released, that is, the first rocker arm 21 and the second rocker arm 22 move relatively independently. When the first rocker arm 21 is actuated, the second rocker arm 22 does not rotate, and the locking link 24 is not driven by external forces. The locking link 24 remains in the locked position, and the door cannot be opened when the user actuates the inner or outer handle.

[0052] The vehicle door lock 100 provided in this application can also be used as a child lock and central lock for the rear door.

[0053] With the central locking system and child lock activated, the user first rotates the interior opening handle. This rotates the interior opening rocker 35, which then abuts the first rocker arm 21 and rotates it. This in turn rotates the second rocker arm 22, which in turn rotates the locking link 24, placing the locking link 24 in the unlocked position. The movement of the first rocker arm 21 and the connecting arm 32 is relatively independent, and the connecting arm 32 does not transmit power to the mating rocker arm 14, which remains locked. The user cannot open the door by operating the interior opening handle. At this point, the locking link 24 is in the unlocked position, allowing the user to operate the exterior opening handle to open the door.

[0054] With the central locking system activated and the child lock in the off position, the user rotates the interior opening handle for the first time. This handle drives the interior opening rocker 35 to rotate. The interior opening rocker 35 abuts the first rocker arm 21 and drives the first rocker arm 21 to rotate. The first rocker arm 21 drives the second rocker arm 22 to rotate. The second rocker arm 22 drives the locking link 24 to rotate, and the locking link 24 is in the unlocked position. Simultaneously, the first rocker arm 21 drives the connecting arm 32 to rotate via the connecting post 312 of the slider 31. The connecting arm 32 abuts the mating rocker arm 14, switching the mating rocker arm 14 from the locked state to the unlocked state, and the door opens.

[0055] While the vehicle is in motion, the child lock is engaged and the inner handle cannot be used to open the door, thereby protecting children. If the vehicle loses power due to a traffic accident, the inner handle can be used to unlock the locking link 24, allowing the user to open the door by operating the outer handle, allowing the occupants to quickly exit the vehicle.

[0056] In some embodiments, the vehicle door lock 100 further includes a first driving assembly 40 , which is configured to drive the locking pin 23 to move to the second driving groove 214 or the second escape groove 215 .

[0057] The first drive assembly 40 includes a first drive member 41, a first transmission member 42, and a lock body slider 43. The first transmission member 42 is rotatably connected between the first drive member 41 and the lock body slider 43. The lock body slider 43 rotates and slidably connects to the locking pin 23, which can be inserted into the lock body slider 43. The output end of the first drive member 41 is rotatably connected to the input end of the first transmission member 42, which is also rotatably connected to the input end of the lock body slider 43. The locking pin 23 is inserted into the lock body slider 43. When the first drive member 41 is activated, the first drive member 41 drives the first transmission member 42 to rotate, which in turn drives the lock body slider 43 to move. The lock body slider 43 drives the locking pin 23 to move to the second drive groove 214 or the second clearance groove 215.

[0058] Among them, the first driving member 41 includes a first motor 411 and a first worm 412, the first worm 412 is passed through the rotating shaft of the first motor 411, the first transmission member 42 includes a first rack portion 421, the first rack portion 421 is geared to the first worm 412, the first rack portion 421 is provided on at least part of the outer peripheral wall of the first transmission member 42, the first rack portion 421 includes a plurality of circumferentially arranged helical teeth, and the plurality of helical teeth are geared to the first worm 412.

[0059] The first transmission member 42 is provided with a positioning slot, and the lock body slider 43 is provided with a positioning post, which is inserted into the positioning slot so that the first transmission member 42 can be rotatably connected to the lock body slider 43. Of course, the first transmission member 42 can also be provided with a positioning post, and the lock body slider 43 can be provided with a positioning slot, and the positioning post is inserted into the positioning slot so that the first transmission member 42 can be rotatably connected to the lock body slider 43.

[0060] The lock slider 43 has multiple limiting ridges on its side facing away from the second rocker arm 22. These ridges are slidably connected to the vehicle door or external housing. These ridges limit the rotation of the lock slider 43, allowing the lock slider 43 to move freely along the long axis of the waist-shaped hole 221. The lock slider 43 has a guide slot 431 extending through it. The second locking portion 232 of the locking pin 23 can be inserted into the guide slot 431. Sliding the lock slider 43 upward or downward can drive the locking pin 23. Alternatively, a guide slot 431 could be provided on the side of the lock slider 43 facing the first rocker arm 21, but not extending through it, to achieve the same effect.

[0061] The first worm gear 412 of the first driving member 41 engages the first rack portion 421 of the first transmission member 42. The positioning post of the first transmission member 42 extends through the positioning slot of the lock body slider 43. The first transmission member 42 rotates to connect with the lock body slider 43, and the second locking portion 232 of the locking pin 23 extends through the slide slot 431 of the lock body slider 43. When the first motor 411 is activated, the first worm gear 412 rotates, which in turn drives the first rack portion 421 of the first driving member 42 to rotate. The first transmission member 42 moves the lock body slider 43, which in turn drives the locking pin 23 to move. Therefore, by controlling the forward and reverse rotation of the first motor 411, the locking pin 23 moves to the second driving slot 214 or the second clearance slot 215.

[0062] In other embodiments, the lock body slider 43 can be omitted, and the locking pin 23 can be directly locked in the first transmission member 42. That is, the rotation of the first transmission member 42 directly drives the locking pin 23 to move. Alternatively, the lock body slider 43 and the first transmission member 42 can be omitted. That is, the first drive member 41 is connected to the locking pin 23, and the locking pin 23 is driven to move by the first drive member 41.

[0063] In some embodiments, the vehicle door lock 100 further includes a second drive assembly 50, which is configured to drive the locking link 24 from the unlocked position to the locked position. The second drive assembly 50 further includes a second drive member 51 and a second transmission member 52. The second drive member 51 and the second transmission member 52 are rotationally connected, and the second transmission member 52 and the locking link 24 are fixedly connected. The second transmission member 52 and the locking link 24 are integrally designed. The output end of the second drive member 51 is rotationally connected to the input end of the second transmission member 52. The second drive member 51 drives the second transmission member 52 and the locking link 24 to rotate together, switching the locking link 24 between the unlocked position and the locked position.

[0064] Among them, the second driving member 51 includes a second motor 511 and a second worm 512, the second worm 512 is passed through the rotating shaft of the second motor 511, the second transmission member 52 includes a second rack portion 521, the second rack portion 521 is geared to the second worm 512, the second rack portion 521 is arranged on at least part of the outer peripheral wall of the second transmission member 52, the second rack portion 521 includes a plurality of circumferentially arranged helical teeth, and the plurality of helical teeth are geared to the second worm 512.

[0065] The second motor 511 of the second drive member 51 drives the second worm 512 to rotate, which in turn drives the second transmission member 52 and the locking link 24 to rotate. By controlling the forward and reverse rotation of the second motor 511, the locking pin 23 moves to the second drive slot 214 or the second clearance slot 215. When the second transmission member 52 drives the locking link 24 and the second transmission member 52 to rotate clockwise, the locking link 24 is in the locked position. When the locking link 24 and the second transmission member 52 rotate counterclockwise, the locking link 24 is in the unlocked position.

[0066] In other embodiments, the second transmission member 52 may be omitted, that is, the second driving member 51 directly drives the locking link 24 to move.

[0070] The following describes the complete operation of the vehicle door lock 100 in detail. It should be understood that the vehicle key includes an unlock button and a lock button. Pressing the lock button once activates the central locking system, while pressing the lock button a second time activates the super lock. Pressing the unlock button disengages both the super lock and the central locking system. The vehicle's rear door is equipped with a child lock button connected to the dial 34.

[0071] The process for closing the central locking system is as follows: Pressing the unlock button on the vehicle key activates the second motor 511, which in turn drives the second worm gear 512. As the second worm gear 512 drives the second transmission member 52 and the locking link 24 counterclockwise, the locking link 24 drives the linkage 11 to the right, placing the locking link 24 in the unlocked position and closing the central locking system.

[0072] When the central locking system is closed, the door opening process is as follows: the inner opening handle drives the inner opening rocker 35 to rotate counterclockwise, the inner opening rocker 35 abuts the first rocker arm 21, and the inner opening rocker 35 drives the first rocker arm 21 to rotate clockwise, and the second rocker arm 22 abuts the matching rocker arm 14 to open the door.

[0073] The central locking system activates as follows: Pressing the vehicle key's lock button activates the second motor 511, which in turn drives the second worm gear 512. When the second worm gear 512 drives the second transmission member 52 and the locking link 24 clockwise, the locking link 24 enters the locked position, and the central locking system is activated.

[0074] When the central locking system is activated, the door opening process proceeds as follows. There are two ways to open the door. First, the interior opening handle is actuated. This first rotates the interior opening rocker 35 counterclockwise, which in turn rotates the first rocker arm 21 clockwise. The first rocker arm 21, via the locking pin 23, rotates the second rocker arm 22 clockwise. The second rocker arm 22 then rotates the locking link 24 counterclockwise, placing the locking link 24 in the unlocked position. Then, the interior opening handle is actuated a second time, rotating the interior opening rocker 35 counterclockwise. The interior opening rocker 35 abuts the first rocker arm 21, which then rotates the first rocker arm 21 counterclockwise. The first rocker arm 21 abuts the mating rocker arm 14, opening the door. In other words, the door can be opened by pulling the interior opening handle twice. Second, pressing the unlock button on the vehicle key drives the second actuator 51 in reverse, placing the locking link 24 in the unlocked position. The door can then be opened directly by actuating either the interior opening handle or the exterior opening handle.

[0075] The movement process of closing the child lock is as follows: the child lock button is driven, and the child lock button drives the knob 34 to rotate counterclockwise, and the knob 34 drives the sliding member 31 to move upward, and the connecting column 312 moves to the first driving groove 211, and the child lock is closed.

[0076] When the child lock is off, the door opening process is as follows: the inner opening handle is actuated, which drives the inner opening rocker 35 to rotate counterclockwise. The inner opening rocker 35 abuts the first rocker arm 21 and drives the first rocker arm 21 to rotate clockwise. The first rocker arm 21 drives the connecting arm 32 to rotate clockwise via the connecting post 312 of the slider 31. The connecting arm 32 drives the mating rocker arm 14 to rotate, and the door opens.

[0077] The motion process of activating the child lock is as follows: the child lock button is driven, and the child lock button drives the knob 34 to rotate clockwise, and the knob 34 drives the sliding member 31 to move downward, and the connecting column 312 moves to the first escape groove 212, and the child lock is activated.

[0078] When the child lock is activated, the movement process for opening the door is as follows. The inner opening handle is driven, which drives the inner opening rocker 35 counterclockwise. The inner opening rocker 35 drives the first rocker arm 21 clockwise. The first rocker arm 21 drives the second rocker arm 22 clockwise via the locking pin 23. The second rocker arm 22 drives the locking link 24 counterclockwise. The locking link 24 is in the unlocked position, and the central locking system is closed. The inner opening handle is driven again, which drives the inner opening rocker 35 counterclockwise. The inner opening rocker 35 contacts and drives the first rocker arm 21 clockwise. The movement of the first rocker arm 21 and the connecting arm 32 is relatively independent, and the connecting arm 32 moves away from the mating rocker arm 14. The user cannot open the door by driving the inner opening handle. However, at this point, the central locking system is closed, and driving the outer opening handle can open the door.

[0079] The process of closing the super lock is as follows: When the unlock button of the vehicle key is pressed for the first time, the unlock button activates the first motor 411, which drives the first worm 412 to rotate. The first worm 412 drives the first transmission member 42 to move counterclockwise. The first transmission member 42 drives the lock body slider 43 to slide downward. The lock body slider 43 drives the locking pin 23 to slide downward. The locking pin 23 is inserted into the second drive slot 214, and the super lock is closed.

[0080] When the central locking system and the Super Lock are activated, the door cannot be opened by operating the inner or outer handles, regardless of whether the child lock is on or off. The Super Lock can be used after the vehicle is parked and the occupant has left the vehicle. The user presses the lock button on the vehicle key to activate the central locking system, and then presses the lock button on the vehicle key again to activate the Super Lock.

[0081] When the central locking system is activated, the super lock is deactivated, and the child lock is activated, the inner opening handle is actuated. The inner opening handle drives the inner opening rocker 35 counterclockwise, which in turn drives the first rocker arm 21 clockwise. The first rocker arm 21 drives the second rocker arm 22 clockwise via the locking pin 23. The second rocker arm 22 drives the locking link 24 counterclockwise, and the locking link 24 is in the unlocked position, closing the central locking system. The inner opening handle is actuated again. The inner opening handle drives the inner opening rocker 35 counterclockwise, which abuts and drives the first rocker arm 21 clockwise. The first rocker arm 21 and the connecting arm 32 move independently, with the connecting arm 32 moving away from the mating rocker arm 14. The user cannot open the door by actuating the inner opening handle. However, at this point, the central locking system is deactivated, allowing the outer opening handle to be actuated. The child lock can be used while driving. The user actuates the dial 34 clockwise to activate the child lock, preventing passengers from accidentally opening the door.
