Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0020] Based on the first aspect of this disclosure, please refer to Figure 1 A door lock device 100 is provided, which includes a child lock component 10 and a central locking component 30. The child lock component 10 is used to drive the central locking component 30 so that the door lock device 100 is in a central locking state.

[0021] Compared to related technologies where child locks and central locking are controlled separately, in this embodiment, the child lock component 10 can drive the central locking component 30, thereby putting the door lock device 100 in a central locking state. By controlling the child lock component 10, the central locking function is realized, thus integrating the child lock component 10 and the central locking component 30 and enriching the functions of the child lock component 10.

[0022] When the door lock device 100 is in the central locking state, the central locking component 30 is decoupled from the outward opening drive chain, thereby preventing the door from opening outward.

[0023] In some embodiments, the door lock device further includes a housing 70, in which the child lock assembly 10 and the central locking assembly 30 are all mounted. The housing 70 can be used to install the child lock assembly 10 and the central locking assembly 30 of the door lock device, thereby protecting the child lock assembly 10 and the central locking assembly 30.

[0024] In some embodiments, the central control assembly 30 includes a central control electrolytic rocker arm 35, which has a first state. The child lock assembly 10 can drive the central control electrolytic rocker arm 35 to the first state so that the door lock device is in a centrally locked state.

[0025] The first state is when the central control electrolytic rocker arm 35 is decoupled from the outward opening drive chain, and the door cannot be opened outward. Similarly, when the central control electrolytic rocker arm 35 is in the first state, it is decoupled from the outward opening drive chain, and the door cannot be opened outward.

[0026] In some examples, the door lock device 100 also has a centrally locked state. When the door lock device 100 is in the centrally locked state, the door cannot be opened outwards. When the door lock device 100 is in the centrally unlocked state, the door can be opened outwards.

[0027] Please combine Figure 6 In some embodiments, the central control component 30 further includes a first central control component 301, which is connected to the central control electrolytic rocker arm 35. The first central control component 301 is used to make the central control electrolytic rocker arm 35 in a first state under the action of the child lock component 10.

[0028] The child lock assembly 10 drives the first central control assembly 301, which in turn drives the central control electrolytic rocker arm 35 to the first state, thereby putting the door lock device into the central control locking state.

[0029] Please combine Figure 6 and Figure 7 In some embodiments, the door lock device further includes a first inward opening component 501, which is used to connect to the child lock component 10 and is connected to the first central control component 301.

[0030] Thus, the child lock assembly 10 drives the first inward opening assembly 501, the first inward opening assembly 501 drives the first central control assembly 301, and the first central control assembly 301 drives the central control electrolytic rocker arm 35 to the first state, thereby putting the door lock device into the central locking state. Please refer to... Figure 7 , Figure 7 The door lock device is in the central locking state. Figure 7 The diagram shows the central control electrolysis rocker arm 35 in its first state.

[0031] Please combine Figure 1 , Figure 6 as well as Figure 7 In some embodiments, the child lock assembly 10 includes a drive assembly 11 and a transmission assembly 13 connected together, the transmission assembly 13 being used to connect to the first inner opening assembly 501.

[0032] In these embodiments, the drive assembly 11 drives the transmission assembly 13, the transmission assembly 13 drives the first inner opening assembly 501, the first inner opening assembly 501 drives the first central control assembly 301, and the first central control assembly 301 drives the central control electrolytic rocker arm 35 to the first state, thereby putting the door lock device in the central control locking state.

[0033] In some embodiments, the drive component 11 may include a motor to provide a power source for the door lock device 100.

[0034] In some embodiments, the transmission assembly 13 includes a turbine 17 and a worm gear 19 connected together, the drive assembly 11 is connected to the worm gear 19, and the turbine 17 is used to connect to the first inward-opening assembly 501.

[0035] In these embodiments, the drive assembly 11 drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate, and the turbine 17 drives the first inward-opening assembly 501 to move.

[0036] In some embodiments, the worm 19 is connected to the motor of the drive assembly 11, and the worm 19 can rotate synchronously with the rotation of the motor shaft of the drive assembly 11. The worm 19 meshes with the worm gear 17, and the worm gear 17 can rotate with the movement of the worm 19.

[0037] In these embodiments, the motor drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate, and the turbine 17 drives the first inward-opening assembly 501 to move. Different directions of rotation of the turbine 17 can be achieved by rotating the motor forward and backward. For example, rotating the motor forward causes the turbine 17 to rotate clockwise, and rotating the motor backward causes the turbine 17 to rotate counterclockwise. Alternatively, rotating the motor backward can cause the turbine 17 to rotate clockwise, and rotating the motor forward can cause the turbine 17 to rotate counterclockwise.

[0038] In some examples, turbine 17 may be mounted on housing 70.

[0039] Please combine Figure 1 , Figure 2 as well as Figure 3 In some embodiments, the first internally opening assembly 501 includes an internally opening connecting crank 55, which is used to drive the internally opening connecting crank 55 to couple with the first central control assembly 301 when the turbine 17 is driven to rotate in a first direction.

[0040] In these embodiments, the drive assembly 11 drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate in a first direction, the turbine 17 will press against the inner opening connecting crank 55, thereby driving the inner opening connecting crank 55 to rotate, so that the inner opening connecting crank 55 rotates to couple with the first central control assembly 301. In this way, the inner opening connecting crank 55 can drive the first central control assembly 301, the first central control assembly 301 can drive the central control electrolytic rocker arm 35 to the first state, thereby putting the door lock device in the central control locking state.

[0041] Please combine Figure 2 In some embodiments, the turbine 17 may be provided with a first cam surface 171, and the inner open connecting crank 55 may be provided with a second cam surface 551. The first cam surface 171 of the turbine 17 presses against the second cam surface 551 of the inner open connecting crank 55, thereby driving the inner open connecting crank 55 to rotate.

[0042] In some examples, please combine Figure 2 , Figure 2 When the door lock device is in the child lock released state, the inner opening connecting crank 55 is provided with a second cam surface 551. When the door lock device is in the child lock released state, the second cam surface 551 does not contact the first cam surface 171 of the turbine 17, the turbine 17 does not drive the inner opening connecting crank 55 to rotate, and the inner opening connecting crank 55 does not interact with the first central control component 301.

[0043] In some examples, please combine Figure 5 , Figure 5The door lock device is in the child lock state and not in the central control lock state. At this time, the second cam surface 551 does not contact the first cam surface 171 of the turbine 17 and does not interact with the first central control component 301.

[0044] In some examples, the first direction can be counterclockwise. Please refer to... Figure 2 , Figure 6 as well as Figure 7 When the door lock device is in the child lock released state, the drive turbine 17 continues to rotate in the first direction. The first cam surface 171 of the turbine 17 rotating in the first direction abuts against the second cam surface 551 of the inner opening connecting crank 55, thereby enabling the turbine 17 to drive the inner opening connecting crank 55 to rotate in the first direction. The inner opening connecting crank 55 drives the first central control component 301, and the first central control component 301 drives the central control electrolytic rocker arm 35 to the first state, thereby putting the door lock device in the central locking state. Please refer to... Figure 7 , Figure 7 The door lock device is in the central locking state. Figure 7 The diagram shows the central control electrolysis rocker arm 35 in its first state.

[0045] In some embodiments, the inwardly opening connecting crank 55 may be located on the housing 70.

[0046] Please combine Figure 1 In some embodiments, the first inner opening assembly 501 includes a third reset member 59, which is connected to the inner opening connecting crank 55.

[0047] In some embodiments, the third reset member 59 may include a torsion spring.

[0048] In some embodiments, the third reset member 59 may be located between the housing 70 and the inner open connecting crank 55 to provide a reset force to the inner open connecting crank 55.

[0049] Please combine Figure 6 as well as Figure 7 In some embodiments, the first central control assembly 301 includes a central control clutch linkage lever 31 and a central control turbine 33. When the turbine 17 is driven to rotate in a first direction, the turbine 17 drives the inner open connecting crank 55, so that the inner open connecting crank 55 drives the central control clutch linkage lever 31 and further drives the central control turbine 33, so that the central control turbine 33 drives the central control electrolytic rocker arm 35 to the first state.

[0050] In these embodiments, the central control turbine 33 can rotate around its rotation axis. When the drive assembly 11 drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate in a first direction. The turbine 17 will press against the inner open connecting crank 55, thereby driving the inner open connecting crank 55 to rotate. The inner open connecting crank 55 can push the central control clutch linkage lever 31, which drives the central control turbine 33 to rotate. When the central control turbine 33 rotates, it will drive the central control electrolytic rocker arm 35 to the first state.

[0051] In some examples, the first direction can be counterclockwise. Please refer to... Figure 2 , Figure 6 as well as Figure 7 The motor drives the worm gear 19 to rotate, which in turn drives the turbine 17 to rotate counterclockwise. The first cam surface 171 of the counterclockwise rotating turbine 17 presses against the second cam surface 551 of the inner-opening connecting crank 55, thereby causing the turbine 17 to drive the inner-opening connecting crank 55 to rotate counterclockwise. The inner-opening connecting crank 55 pushes the central control clutch linkage lever 31, which in turn drives the central control turbine 33. The central control turbine 33 drives the central control electrolytic rocker arm 35 to the first state, thus putting the door lock device in the central locking state. Please refer to... Figure 7 , Figure 7 The door lock device is in the central locking state. Figure 7 The diagram shows the central control electrolysis rocker arm 35 in its first state.

[0052] In some embodiments, the central control turbine 33 may be located on the housing 70.

[0053] In some embodiments, the central control electrolytic rocker arm 35, the central control turbine 33, and the inner opening rocker arm 53 can be coaxially arranged. Along the axial direction of the central control electrolytic rocker arm 35, the central control electrolytic rocker arm 35 can be located between the central control turbine 33 and the inner opening rocker arm 53, wherein the central control electrolytic rocker arm 35 is located on the side of the central control turbine 33 facing away from the housing 70. In some embodiments, the central control electrolytic rocker arm 35 can be pushed by the central control turbine 33 and the central control clutch linkage lever 31. When the central control electrolytic rocker arm 35 is pushed to a first state, the door lock device 100 is in a centrally locked state.

[0054] In some embodiments, the central clutch linkage lever 31 may be located above the inner rocker arm 53 and the central turbine 33.

[0055] Please combine Figure 7 In some embodiments, the central control turbine 33 is provided with a driving part 331, and the central control electrolysis rocker arm 35 is provided with a cooperating part 351 that cooperates with the driving part 331. When the central control turbine 33 rotates under the drive of the turbine 17, the driving part 331 drives the cooperating part 351 to drive the central control electrolysis rocker arm 35 to the first state.

[0056] The driving part 331 can be a protruding structure provided in the central control turbine 33, and the mating part 351 can be a groove provided in the central control electrolytic rocker arm 35. The protruding structure of the central control turbine 33 abuts against the groove of the central control electrolytic rocker arm 35, thereby rotating the central control turbine 33 and driving the central control electrolytic rocker arm 35 to rotate to the first state, so that the door lock device 100 is in the central locking state. In some examples, the first direction can be counterclockwise. Please refer to... Figure 2 , Figure 6 as well as Figure 7 The motor drives the worm gear 19 to rotate, which in turn drives the turbine 17 to rotate counterclockwise. The first cam surface 171 of the counterclockwise rotating turbine 17 abuts against the second cam surface 551 of the inner connecting crank 55, thus causing the turbine 17 to drive the inner connecting crank 55 to rotate counterclockwise. The inner connecting crank 55 pushes the central clutch linkage lever 31, which in turn drives the central control turbine 33. The protruding structure of the central control turbine 33 abuts against the groove of the central control electrolytic rocker arm 35, causing the central control electrolytic rocker arm 35 to rotate, bringing it to its first state. This puts the door lock device in the central locking state. Please refer to... Figure 7 , Figure 7 The door lock device is in the central locking state. Figure 7 The diagram shows the central control electrolysis rocker arm 35 in its first state.

[0057] Please combine Figure 1 as well as Figure 2 In some embodiments, the door lock device further includes a second inward opening component 503, and the child lock component 10 is used to couple the second inward opening component 503 with the central control electrolytic rocker arm 35, so that the door lock device is in the child lock state; or

[0058] The child lock assembly 10 is used to decouple the second inner opening assembly 503 from the central control electrolytic rocker arm 35, so that the door lock device is in the child lock released state.

[0059] In these embodiments, the door lock device has a child lock state and a child lock release state. When the door lock device is in the child lock release state, the inward pull is ineffective, meaning that the user cannot open the door by pulling the inner door handle. When the door lock device is in the child lock state, that is, the child lock is not released, the inward pull is active, meaning that the user can open the door by pulling the inner door handle. The child lock state is the opposite of the child lock release state. Please refer to... Figure 4 , Figure 4 The middle door lock is in the child lock released position. Please refer to... Figure 5 , Figure 5 The middle door lock is in the child lock position.

[0060] In some embodiments, when the door lock device is in the central locking state, it can be opened by pulling the inside door handle once. When the door lock device is in the child lock released state, it cannot be opened by pulling the inside door handle once.

[0061] In the embodiments of this application, the door lock device 100 has a central locking state, a child lock state, and a child lock release state. In other words, the door lock device 100 integrates three functions: central locking, child lock locking, and child lock release. By controlling the movement of the child lock component 10, the central locking state, child lock locking state, and child lock release state of the door lock device 100 can be switched, allowing the door lock device 100 to be in different states. Thus, the door lock device structurally meets the design requirements for realizing multiple functions.

[0062] It should be noted that in some examples, the door lock device 100 also has a central locking state and a central unlocking state. When the door lock device 100 is in the central unlocking state, the central locking component 30 is coupled with the outward opening drive chain, allowing the door to open outward. When the door lock device 100 is in the central locking state, the central locking component 30 is decoupled from the outward opening drive chain, thus preventing the door from opening outward.

[0063] Central locking and unlocking control the doors to prevent or allow them to open outwards. Child lock locking and unlocking control the doors to allow or prevent them to open inwards. Specifically:

[0064] When the door lock device 100 is in the central locking state and the child lock state, the inward pull is activated, meaning the child lock is not released. At this time, the door cannot be opened outward, but can be opened inward.

[0065] When the door lock device 100 is in the central locking state and the child lock is in the released state, that is, the child lock is released and the inward pull is ineffective, the door cannot be opened outward or inward.

[0066] When the door lock device 100 is in the central unlock state and the door lock device 100 is in the child lock state, the inward pull is activated, that is, the child lock is not released, the door can be opened outward and the door can be opened inward.

[0067] When the door lock device 100 is in the central locking unlock state and the child lock is in the child lock released state, the inward pull is ineffective, the door cannot be opened inward, but the door can be opened outward.

[0068] In the embodiments of this application, please refer to Figure 5 , Figure 5When the central door lock is in the child lock state, and the inward opening cable 505 is pulled, it pulls the inward opening rocker arm 53, causing it to rotate. This rotation drives the first connecting end 511, which in turn drives the central control electrolytic rocker arm 35 coupled to the first connecting end 511, thus opening the door inward. Furthermore, when the door lock is in the child lock state, the drive turbine 17 rotates counterclockwise, for example, it can... Figure 5 Rotate the position counterclockwise to Figure 4 The position shown releases the limiting relationship between the first connecting end 511 and the central control electrolytic rocker arm 35. When the inward opening cable 505 is pulled, although it causes the inward opening rocker arm 53 to rotate, it cannot drive the central control electrolytic rocker arm 35 to move, thus preventing the door from opening inward. At this time, the door lock device is in the child lock released state. Furthermore, when the door lock device is in the child lock released state, it further drives the turbine 17 to rotate counterclockwise, for example, it can automatically... Figure 4 Rotate the position counterclockwise to Figure 7 As shown in the figure, when the door lock device is in the child lock released state, the turbine 17 is further driven to rotate counterclockwise, so that the door lock device is in the central locking state.

[0069] In some embodiments, the child lock assembly 10 includes a drive assembly 11 and a transmission assembly 13 connected together, the transmission assembly 13 being used to connect to the second inner opening assembly 503.

[0070] In these embodiments, the drive assembly 11 drives the transmission assembly 13, which in turn drives the second inner opening assembly 503, thereby coupling the second inner opening assembly 503 with the central control electrolytic rocker arm 35 to put the door lock device in the child lock state; or decoupling the second inner opening assembly 503 from the central control electrolytic rocker arm 35 to put the door lock device in the child lock released state.

[0071] In some embodiments, the transmission assembly 13 includes a turbine 17 and a worm gear 19 connected together, the drive assembly 11 is connected to the worm gear 19, and the turbine 17 is used to connect to the second inward-opening assembly 503.

[0072] In these embodiments, the drive assembly 11 drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate, and the turbine 17 drives the second inward-opening assembly 503 to move.

[0073] In some embodiments, the worm 19 is connected to the motor of the drive assembly 11, and the worm 19 can rotate synchronously with the rotation of the motor shaft of the drive assembly 11. The worm 19 meshes with the worm gear 17, and the worm gear 17 can rotate with the movement of the worm 19.

[0074] In some examples, the motor drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate, and the turbine 17 drives the second inward-opening assembly 503 to move.

[0075] In some embodiments, when the turbine 17 is driven to rotate in the second direction, the turbine 17 is used to drive the second inner opening assembly 503 to couple with the central control electrolytic rocker arm 35.

[0076] Please combine Figure 6 as well as Figure 7 In these embodiments, the first direction and the second direction are different directions. In some examples, when the door lock device is in the child lock released state, the door lock device can be locked in the child lock state by driving the turbine 17 to rotate in the second direction. When the door lock device is in the child lock locked state, the door lock device can be locked in the child lock released state by driving the turbine 17 to rotate in the first direction. When the door lock device is in the child lock released state, the door lock device can be locked in the child lock released state and simultaneously locked in the central locking state by further driving the turbine 17 to rotate in the first direction.

[0077] In some examples, when the turbine 17 is driven to rotate in the first direction, the turbine 17 presses against the inner opening connecting crank 55, thereby driving the inner opening connecting crank 55 to rotate. The inner opening connecting crank 55 drives the first central control component 301, which in turn drives the central control electrolytic rocker arm 35 to the first state, thus putting the door lock device in the central control locking state. In some examples, when the turbine 17 is driven to rotate in the second direction, the turbine 17 drives the second inner opening component 503 to couple with the central control electrolytic rocker arm 35, thereby putting the door lock device in the child lock state. In this way, by driving the rotation of the turbine 17, the door lock device can be in both the central control locking state and the child lock state. When the door lock device 100 is in the child lock state, the door lock device can be switched from the child lock state to the child lock release state by driving the turbine 17 to rotate counterclockwise. The door lock device can be switched from the child lock release state to the central control locking state by driving the turbine 17 to rotate counterclockwise further.

[0078] In some examples, the first direction can be counterclockwise and the second direction can be clockwise.

[0079] In some embodiments, the second inward-opening assembly 503 includes an inward-opening rocker arm 53, which is used to couple the inward-opening rocker arm 53 to the central control electrolytic rocker arm 35 when the turbine 17 is driven to rotate in the second direction.

[0080] In these embodiments, the drive assembly 11 drives the worm gear 19 to rotate, and the worm gear 19 drives the turbine 17 to rotate in the second direction, so that the inner opening rocker arm 53 is coupled with the central control electrolytic rocker arm 35, thereby enabling the door lock device to be in the child lock state.

[0081] In some examples, the inward-opening rocker arm 53 may be located on the housing 70.

[0082] In some embodiments, the second inward opening assembly 503 further includes an inward opening pull wire 505, which is used to connect to the door handle and the inward opening rocker arm 53, respectively.

[0083] In these embodiments, one end of the inward-opening cable 505 can be connected to the interior door handle, and the other end can be connected to one end of the inward-opening rocker arm 53. The user can operate the interior door handle by pulling it, causing the inward-opening cable 505 to move, which in turn causes one end of the inward-opening rocker arm 53 to rotate around an axis. When the door lock device 100 is in the child lock state, pulling the inward-opening cable 505 can further rotate the inward-opening rocker arm 53. The rotating inward-opening rocker arm 53 can further drive the central control electrolytic rocker arm 35, thereby unlocking the door from the inside and realizing inward opening of the door.

[0084] In some examples, the inner opening pull wire 505 is pulled, which can drive the inner opening rocker arm 53 to rotate counterclockwise.

[0085] In these embodiments, the door lock device has a child lock engaged state and a child lock disengaged state. When the door lock device is in the child lock disengaged state, the inward pull is disabled, meaning that the user cannot open the door by pulling the inside door handle. When the door lock device is in the child lock engaged state, the inward pull is engaged, meaning that the user can open the door by pulling the inside door handle.

[0086] In some examples, the turbine 17 can be rotated in a second direction by a motor, further driving the second inward opening assembly 503, which couples with the central control electrolytic rocker arm 35, thereby putting the door lock device in the child lock state. At this time, pulling the inward opening cable 505 can drive the inward opening rocker arm 53 of the second inward opening assembly 503 to rotate, and the inward opening rocker arm 53 drives the central control electrolytic rocker arm 35, thereby unlocking the door from the inside.

[0087] In some examples, the turbine 17 can be controlled by a motor to rotate counterclockwise, which in turn drives the second inner opening component 503, thereby decoupling the second inner opening component 503 from the central control electrolytic rocker arm 35, thus putting the door lock device in the child lock released state.

[0088] In some examples, the turbine 17 can be further rotated counterclockwise by the motor until the turbine 17 drives the inner opening connecting crank 55 to rotate counterclockwise. The inner opening connecting crank 55 drives the first central control component 301, and the first central control component 301 drives the central control electrolytic rocker arm 35 to the first state, thereby putting the door lock device in the central control locking state.

[0089] Please combine Figure 1 , Figure 3 In some embodiments, the transmission assembly 13 further includes a first reset member 12, which is connected to the turbine 17.

[0090] The first reset element 12 may include a reset torsion spring, which may be disposed between the housing 70 and the turbine 17. The reset torsion spring is connected to the turbine 17 to provide a reset force to the turbine 17. In some examples, when the turbine 17 is in a state of... Figure 2 When in position, the first reset member 12 does not generate a reset force.

[0091] In some examples, when the door lock device is in the child lock released state, please combine Figure 2 as well as Figure 4 At this time, the worm gear 19 and the turbine 17 are engaged, the first reset member 12 does not generate a reset force, and the second connecting end 513 of the inner unlocking release member 51 abuts against one side of the second movable groove 172 on the turbine 17. Please combine Figure 4 , Figure 4 The second connecting end 513 abuts against the right side wall of the second movable groove 172 on the turbine 17, and the first connecting end 511 of the inner unlocking release member 51 is engaged in the first movable groove 531. Figure 4 The first connecting end 511 is located in the middle of the first movable groove 531, and the first connecting end 511 does not abut against the right or left side wall of the second movable groove 172. At this time, there is no transmission relationship between the inner opening connecting crank 55 and the turbine 17, the turbine 17 does not drive the inner opening connecting crank 55 to rotate, and the inner opening connecting crank 55 does not interact with the first central control component 301. At this time, the door lock device is in the child lock released state, the inner pull mechanical structure fails, and pulling the inner opening pull cable 505 cannot open the door inward.

[0092] In some embodiments, the second inner opening component 503 includes an inner opening release member 51. When the inner opening release member 51 is driven to couple with the central control electrolytic rocker arm 35, the door lock device is in a child lock state.

[0093] In these embodiments, the drive assembly 11 drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate, and the turbine 17 drives the inner unlocking release member 51, thereby coupling or decoupling the inner unlocking release member 51 with the central control electrolytic rocker arm 35. When the inner unlocking release member 51 is coupled with the central control electrolytic rocker arm 35, the door lock device is in the child lock state, that is, the child lock is not released. At this time, by pulling the inner opening pull cable 505, the inner opening pull cable 505 drives the inner opening rocker arm 53, which can drive the inner unlocking release member 51 and drive the central control electrolytic rocker arm 35 to move, thereby enabling the door to open inward.

[0094] When the inner unlock release component 51 is decoupled from the central control electrolytic rocker arm 35, the inner opening pull cable 505 is pulled, and the inner opening pull cable 505 drives the inner opening rocker arm 53. The inner opening rocker arm 53 cannot drive the central control electrolytic rocker arm 35 to move, so the door cannot be prevented from opening inward.

[0095] In some examples, the internal unlocking release 51 may be located below the turbine 17.

[0096] Please combine Figure 2 In some embodiments, the internal unlocking release member 51 includes a first connecting end 511, and the internal unlocking rocker arm 53 is provided with a first movable groove 531. At least part of the first connecting end 511 is located in the first movable groove 531. When the turbine 17 is driven to rotate in the second direction, the turbine 17 is used to drive the first connecting end 511 of the internal unlocking release member 51 to move along the first movable groove 531 to couple with the central control electrolytic rocker arm 35.

[0097] In these embodiments, the drive assembly 11 drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate in the second direction, the turbine 17 drives the inner unlocking release member 51 to move, and the first connecting end 511 of the inner unlocking release member 51 moves along the first movable groove 531 of the inner opening rocker arm 53 to couple with the central control electrolytic rocker arm 35.

[0098] In some examples, please combine Figure 4 as well as Figure 5 It can be that the motor drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate clockwise, and the clockwise rotating turbine 17 drives the inner unlocking release component 51 to... Figure 4 The left side of the movement causes the first connecting end 511 of the inner unlocking release member 51 to move to the left side of the first movable groove 531 of the inner unlocking rocker arm 53 (please refer to...). Figure 5 , Figure 5 When the first connecting end 511 is located to the left of the first movable slot 531 of the inner opening rocker arm 53, the central control electrolytic rocker arm 35 can limit the first connecting end 511, thereby realizing the coupling between the central control electrolytic rocker arm 35 and the first connecting end 511, and thus the inner opening rocker arm 53 and the central control electrolytic rocker arm 35 are coupled.

[0099] The central control electrolytic rocker arm 35 limits the first connecting end 511. Specifically, the limiting method can be: the central control electrolytic rocker arm 35 is limited by the first connecting part and the second connecting part 515 of the inner unlocking release member 51. Please refer to... Figure 1 and Figure 7 The first connecting portion may include a protrusion 353 and a groove 355, and the second connecting portion 515 may be a part of the first connecting end 511. When the first connecting end 511 moves to the point of connection... Figure 5As shown, when it is on the left side of the first movable groove 531 of the inward-opening rocker arm 53, at least part of the second connecting portion 515 is located in the groove 355 and abuts against the protrusion 353. Due to the provision of the third reset member 59, under the action of the third reset member 59, the first connecting end 511 moves to the position indicated by the connection. Figure 5 When the position shown is to the left of the first movable groove 531 of the inward-opening rocker arm 53, the first connecting end 511 can always be kept in this position, so that the second connecting part 515 always has a limiting relationship with the second connecting part 515 of the first connecting end 511. In this way, when the inward-opening pull cable 505 is pulled, the inward-opening pull cable 505 can pull the inward-opening rocker arm 53, causing the inward-opening rocker arm 53 to rotate. When the inward-opening rocker arm 53 rotates, it will drive the first connecting end 511, and further drive the central control electrolytic rocker arm 35 coupled with the first connecting end 511 to move, so as to realize the inward opening of the door.

[0100] In some embodiments, the turbine 17 is provided with a second movable groove 172, and the internal unlocking release member 51 includes a second connecting end 513, at least a portion of which is located within the second movable groove 172 and is movable within the second movable groove 172.

[0101] The second movable groove 172 can form a mating relationship with the second connecting end 513. As the turbine 17 rotates, the side wall of the second movable groove 172 of the turbine 17 can drive the second connecting end 513 of the inner unlocking release member 51 to move. The first connecting end 511 of the inner unlocking release member 51 forms a mating relationship with the first movable groove 531 of the inner opening rocker arm 53.

[0102] In some examples, the movement of the inner unlocking release member 51 can be controlled by the second movable groove 172 of the turbine 17. The second connecting end 513 of the inner unlocking release member 51 can move along the second movable groove 172, which can keep the door lock device in the child lock released state.

[0103] Please combine Figure 6 In some embodiments, the second movable groove 172 includes a first limiting wall 173, which is used to drive the second connecting end 513 to move when the turbine 17 is driven to rotate in the second direction.

[0104] In these embodiments, the drive assembly 11 drives the worm gear 19 to rotate, the worm gear 19 drives the turbine 17 to rotate in the second direction, and when the first limiting wall 173 of the second movable groove 172 of the turbine 17 rotates to abut against the second connecting end 513, the turbine 17 rotating in the second direction will drive the second connecting end 513 to move.

[0105] In some embodiments, the second movable groove 172 further includes a second limiting wall 175, which is spaced apart from the first limiting wall 173. When the turbine 17 rotates in the first direction, the second limiting wall 175 is used to drive the second connecting end 513 to move.

[0106] The second movable groove 172 cooperates with the inner unlocking release component 51. When the turbine 17 rotates, it drives the inner unlocking release component 51 so that the door lock device is in the child lock state or the child lock release state.

[0107] In some examples, the drive assembly 11 drives the worm gear 19 to rotate, and the worm gear 19 drives the turbine 17 to rotate in the second direction. When the first limiting wall 173 of the second movable groove 172 of the turbine 17 rotates in the second direction to abut against the second connecting end 513, it will drive the second connecting end 513 toward the second direction. Figure 4 The movement to the left side causes the inner unlocking release element 51 to move towards... Figure 4 The left side of the movement allows the first connecting end 511 to move along the first movable groove 531. Figure 4 The left side moves within. It should be noted that when the turbine 17 rotates in the second direction, the first reset member 12 generates a reset force. When the first connecting end 511 moves towards... Figure 4 The left side moves until it abuts against the side wall of the first movable groove 531. Please combine... Figure 5 , Figure 5 The first connecting end 511 abuts against the first movable groove 531 of the inner rocker arm 53. When the first connecting end 511 moves towards... Figure 4 When the left side of the door moves to abut against the side wall of the first movable groove 531, the first connecting end 511 couples with the central control electrolytic rocker arm 35. At this time, the door lock device is in the child lock state, and pulling the inward opening cable 505 can complete the inward opening door action. When the first connecting end 511 moves to the left side, the door lock device is in the child lock state. Pulling the inward opening cable 505 can complete the inward opening door action. Figure 4 When the left side of the turbine moves to abut against the side wall of the first movable groove 531, the reset force of the first reset member 12 can be applied. Driven by the first reset member 12, the turbine 17 rotates along the first direction to return to the initial position, thereby causing the second limiting wall 175 to abut against the second connecting end 513.

[0108] When it is necessary to switch the door lock device from the child lock state to the child lock release state, the drive turbine 17 rotates in the first direction. At this time, the second limiting wall 175 can drive the second connecting end 513 to rotate in the first direction, thereby driving the first connecting end 511 to move along the first movable groove 531, specifically along the first movable groove 531 towards... Figure 5The right side of the mechanism moves, thus decoupling the second connecting end 513 from the central control electrolytic rocker arm 35. This causes the inner pull mechanical structure to fail, and pulling the inner opening cable 505 cannot complete the inner door opening action. At this time, the door lock device switches to the child lock release state. At this time, the turbine 17 can still maintain a certain distance from the inner opening connecting crank 55, so it will not drive the inner opening connecting crank 55 to move.

[0109] When the door lock device is in the child lock released state, the drive turbine 17 continues to rotate in the first direction, which further enables the door lock device to be in the central locking state simultaneously with the child lock released state. Please refer to... Figure 6 and Figure 7 The central locking signal can be input to the motor of the drive assembly 11. The motor of the drive assembly 11 starts, and the output shaft of the motor rotates, causing the worm gear 19 to rotate passively, which drives the worm gear 17 meshing with it to rotate counterclockwise. During the rotation, the first reset member 12 generates a reset force. At this time, the second cam surface 551 of the inner open connecting crank 55 contacts the first cam surface 171 of the worm gear 17. The worm gear 17 rotates in the first direction, which drives the inner open connecting crank 55 to rotate counterclockwise, thereby pushing the central control clutch linkage lever 31. At this time, the central control worm gear 33 rotates in the first direction. The driving part 331 of the central control worm gear 33 can drive the cooperating part 351 of the central control electrolytic rocker arm 35, thereby driving the central control electrolytic rocker arm 35 to rotate counterclockwise, so that the door lock device 100 is in the central control locking state.

[0110] In some embodiments, the second inner opening component 503 includes a switching element 57 connected to the inner opening release element 51.

[0111] The switching element 57 may include a spring and may be located between the housing 70 and the inner unlocking release element 51, thereby enabling the inner unlocking release element 51 to be provided with a reset force.

[0112] In some examples, please refer to Figure 5 When the first connecting end 511 of the internal unlocking release component 51 is in Figure 5 When the first connecting end 511 is in the middle position, it abuts against the left side wall of the first movable groove 531. The first connecting end 511 of the inner unlocking release member 51 is coupled with the central control electrolytic rocker arm 35. At this time, the switching member 57 can keep the first connecting end 511 always in the position coupled with the central control electrolytic rocker arm 35. Please refer to Figure 5The switching element 57 can keep the first connecting end 511 always abutting against the left side wall of the first movable groove 531, thereby maintaining coupling with the central control electrolytic rocker arm 35. In some examples, the switching element 57 can be a spring. When the first connecting end 511 is in the middle position of the first movable groove 531, the switching element 57 is not subjected to torque. When the first connecting end 511 is on the left or right side of the first movable groove 531, the first connecting end 511 can be kept abutting against the left or right side wall of the first movable groove 531 under the action of the switching element 57. Please refer to... Figure 5 , Figure 5 The first connecting end 511 is driven to abut against the left side wall of the first movable groove 531. Under the action of the switching member 57, the switching member 57 can keep the first connecting end 511 abutting against the left side wall of the first movable groove 531, so that the first connecting end 511 is always coupled with the central control electrolytic rocker arm 35.

[0113] In some examples, the internal unlocking release 51 and the turbine 17 can be connected via a switch 57.

[0114] Firstly, in related technologies, existing electronic child locks have long locking and releasing transmission paths, and require numerous parts such as rivets, fixed gears, and internal connecting parts to achieve transmission. The complex coordination between these parts leads to low production efficiency and high manufacturing costs. Furthermore, the functional areas are widely dispersed, resulting in low transmission efficiency and a large space occupation. This application reduces the number of transmission mechanisms while improving functionality. By controlling the movement of the turbine 17, it is possible to switch between the central locking state, child lock locking state, and child lock release state of the door lock device 100, allowing the door lock device 100 to be in different states. The structure is simpler, the transmission method is streamlined, the size of the door lock device is further reduced, and installation space is saved. It also provides a solution for achieving overall vehicle lightweighting.

[0115] Secondly, in this application, the turbine 17 enables efficient transmission. Through innovative design of the turbine 17 structure, multiple functions are integrated into a single turbine 17. By controlling the movement of the turbine 17, the central locking state, child lock state, and child lock release state of the door lock device 100 can be switched, meeting the needs of multiple functions of the door lock device. The structure is simple, saving mechanical components; the layout is compact, reducing the size of the door lock device 100 and saving installation space. Furthermore, the transmission is more efficient, providing convenience for the driver's electronic control of the door lock device. It reduces the probability of transmission failure due to the complexity of parts, further improving the safety and reliability of the door lock device 100.

[0116] Specifically, in this embodiment, the turbine 17 may be provided with a first cam surface 171. The first cam surface 171 of the turbine 17 abuts against the inner opening connecting crank, thereby driving the inner opening connecting crank 55 to rotate, so that the door lock device is in a central locking state. The central locking function is integrated on the turbine 17, which greatly reduces the transmission path between functional areas, reduces the number of connecting elements, transmission rods and other mechanisms, improves the efficiency of turbine transmission, and also provides convenience for the driver's seat to control the electronic lock. At the same time, in conjunction with the second movable groove 172 of the turbine 17, the movement path between the inner opening release element, the inner opening rocker arm and the inner opening connecting crank 55 is reasonably controlled to achieve the corresponding functions.
