[0070] Referring to the accompanying drawings, this application provides a door lock structure that can be used in vehicles, such as fuel-powered cars and new energy electric vehicles, and can realize the functions of opening and locking the vehicle door.

[0071] The door lock structure includes:

[0072] Locking tongue assembly 33, which includes locking arm 331 and locking tongue 332;

[0073] The outer locking part 32 includes a first transmission member 322, which can move between a first position and a second position. When the first transmission member 322 is in the first position, it can drive the locking arm 331 to move to decouple from the locking tongue 332. When the first transmission member 322 is in the second position, it cannot drive the locking arm 331 to move to decouple from the locking tongue 332.

[0074] The inner locking part 31 includes a switch and a transmission assembly that can be operated by the user. The switch is connected to the first transmission member 322 through the transmission assembly. When the transmission assembly is in the first transmission state, the switch can drive the first transmission member 322 from the second position to the first position through the transmission assembly. When the transmission assembly is in the second transmission state, the switch cannot drive the first transmission member 322 from the second position to the first position through the transmission assembly.

[0075] As shown in Figures 11 to 13, the locking tongue assembly 33 in this embodiment may include a locking arm 331 and a locking tongue 332. The locking tongue 332 may be mounted on the sixth rotating shaft 006 and can rotate around the sixth rotating shaft 006 under the drive of the locking ring (not shown). The locking arm 331 may be mounted on the fourth rotating shaft 004 and can rotate around the fourth rotating shaft 004 under the drive of the first transmission member 322, so that the locking arm 331 and the locking tongue 332 are decoupled and unlocked.

[0076] Specifically, as shown in Figures 11 to 13, the locking process is as follows: the bolt 332 rotates clockwise under the drive of the locking ring until the first groove 3321 on the bolt 332 abuts against the third protrusion 3311 on the locking arm 331, thus achieving the first locking; the locking ring continues to drive the bolt 332 to rotate clockwise until the second groove 3322 on the bolt 332 abuts against the third protrusion 3311 on the locking arm 331, thus achieving the second locking.

[0077] Figures 8 and 9 illustrate the unlocking process. The locking arm 331 has a second protrusion 3312. A first transmission member 322, located in a first position, at least partially corresponds to the second protrusion 3312, thereby facilitating the first transmission member 322 to drive the locking arm 331 in a coupled state. For example, when the second rocker arm 321 rotates clockwise, it can drive the first transmission member 322 to rotate clockwise as well, causing the first transmission member 322 to push the locking arm 331 to move counterclockwise (Figures 11 to 13) until the locking arm 331 is decoupled from the latch 332, thus unlocking the device.

[0078] The first transmission component 322 can be a rod-shaped structure, such as a long, thin, cylindrical, or curved shape, or it can be a plate-shaped structure or other structures. Driven by the transmission assembly, the first transmission component 322 can move between a first position and a second position to control the decoupling of the locking arm 331 and the locking tongue 332, that is, to control the state of the locking tongue assembly 33.

[0079] Specifically, the position control of the first transmission component 322 can be achieved through user-operable switches and transmission assemblies. The switches can adjust the state of the transmission assembly via mechanical structures or signals, enabling the transmission assembly to switch between a first transmission state and a second transmission state. The switches include, but are not limited to, user-operable knobs, buttons, levers, etc. The transmission assembly includes one or more mutually transmitting transmission components.

[0080] When the transmission assembly is in the first transmission state, the switching element can drive the first transmission member 322 from the second position to the first position, as shown in Figure 17, through the transmission assembly. At this time, the first transmission member 322 is coupled with the locking arm 331, and the first transmission member 322 can drive the locking arm 331 to move until it is decoupled from the bolt 332, thereby unlocking the door lock. At this time, both the inner opening mechanism with the inner locking part 31 and the outer opening mechanism with the outer locking part 32 can unlock the door lock.

[0081] When the transmission assembly is in the second transmission state, the switch cannot drive the first transmission member 322 from the second position to the first position via the transmission assembly. At this time, the first transmission member 322 is located in the second position, as shown in Figure 18. In this state, the first transmission member 322 is decoupled from the locking arm 331, and cannot drive the locking arm 331 to move to decouple from the bolt 332, thus preventing the door lock from unlocking. At this time, neither the inner opening mechanism with the inner locking part 31 nor the outer opening mechanism with the outer locking part 32 can unlock the door. Therefore, the unlocking capabilities of the inner and outer opening mechanisms can be adjusted simultaneously through the control of the switch, simplifying the control of the door lock structure and facilitating its miniaturization.

[0082] Optionally, the transmission assembly includes a first rocker arm 3113 and a second connecting arm 3111. The switch is connected to the first rocker arm 3113. The first rocker arm 3113 can transmit power to the second connecting arm 3111. The second connecting arm 3111 is used to drive the first transmission member 322 to move.

[0083] As shown in Figures 20 and 21, the switch can be connected to the first rocker arm 3113, so that the switch can drive the first rocker arm 3113 to move, so as to form a power transmission path between the first rocker arm 3113, the second connecting arm 3111, and the first transmission member 322. This allows the first transmission member 322 to couple with the locking arm 331, so that the first transmission member 322 can drive the locking arm 331 to move until it is decoupled from the bolt 332, thereby realizing the unlocking of the door lock.

[0084] Optionally, it also includes a first connecting arm 1, which is movable between a first coupling position and a first decoupling position; when the first connecting arm 1 is placed in the first coupling position, the first rocker arm 3113 drives the first connecting arm 1, so that the first connecting arm 1 can drive the first transmission member 322 to move to the first position through the second connecting arm 3111.

[0085] When the first connecting arm 1 is in the first decoupling position, the first rocker arm 3113 cannot drive the first connecting arm 1, so that the first connecting arm 1 cannot drive the first transmission member 322 to move to the first position through the second connecting arm 3111.

[0086] As shown in Figures 20 and 21, when the first connecting arm 1 moves to the first coupling position, the first connecting arm 1 is coupled with the first rocker arm 3113, and power can be transmitted between the first connecting arm 1 and the first rocker arm 3113. When the first rocker arm 3113 is pulled, the first rocker arm 3113 can drive the second connecting arm 3111 to move through the first connecting arm 1. The second connecting arm 3111 can drive the first transmission member 322 to move to the first position, thereby unlocking the outer locking part 32.

[0087] When the first connecting arm 1 moves to the first decoupling position, the first connecting arm 1 is decoupled from the first rocker arm 3113, and power transmission cannot be performed between the first connecting arm 1 and the first rocker arm 3113. When the first rocker arm 3113 is pulled, the first rocker arm 3113 cannot drive the second connecting arm 3111 to move through the first connecting arm 1, and the second connecting arm 3111 cannot drive the first transmission member 322 to move to the first position. The first transmission member 322 remains in the second position, causing the outer locking part 32 to lock.

[0088] Optionally, it also includes a first drive source 21, which is capable of driving the first connecting arm 1 to move between a first decoupling position and a first coupling position.

[0089] As shown in Figures 1 to 3, the first drive source 21 includes, but is not limited to, structures such as a motor, cylinder, and worm gear. The first drive source 21 is used to output driving force to the first connecting arm 1. Under the drive of the first drive source 21, the first connecting arm 1 can move between a first decoupling position and a first coupling position. Depending on the specific structural design of the door lock, the movement of the first connecting arm 1 includes, but is not limited to, rotation and translation.

[0090] Optionally, it also includes a second transmission member 22, one end of which is connected to the first drive source 21, and the other end of which is connected to the first connecting arm 1;

[0091] Driven by the first driving source 21, the first connecting arm 1 can move between the first coupling position and the first decoupling position.

[0092] As shown in Figures 1 to 3, the first drive source 21 can output driving force to the second transmission member 22. The second transmission member 22 can transmit the driving force output by the first drive source 21 to the connected first connecting arm 1. Under the drive of the first drive source 21, the second transmission member 22 can move and drive the first connecting arm 1 to move, thereby enabling the first connecting arm 1 to move between the first decoupling position and the first coupling position. The second transmission member 22 can be a rod-shaped structure, such as being elongated, cylindrical, curved, or other shapes; it can also be a plate-shaped structure or other structures.

[0093] Optionally, the transmission assembly further includes a third transmission member 3252, one end of which is connected to the second connecting arm 3111, and the other end of which is connected to the first transmission member 322. The third transmission member 3252 can drive the first transmission member 322 to move between the first position and the second position.

[0094] As shown in Figures 17 to 22, the switch can be connected to the first rocker arm 3113, so that the switch can drive the first rocker arm 3113 to move and form a power transmission path between the first rocker arm 3113, the second connecting arm 3111, the third transmission member 3252, and the first transmission member 322. This can drive the first transmission member 322 to couple with the locking arm 331, so that the first transmission member 322 can drive the locking arm 331 to move until it is decoupled from the bolt 332, thereby realizing the door lock unlocking.

[0095] By designing a third transmission component 3252 to connect the second connecting arm 3111 and the first transmission component 322, the force transmission path of the first transmission component 322 can be increased, facilitating the control of the position of the first transmission component 322. The third transmission component 3252 can be a rod-like structure, such as a slender, cylindrical, or curved shape, or it can be a plate-like structure or other irregular structures.

[0096] Optionally, the transmission assembly further includes a fourth transmission member 323, which is connected to the first transmission member 322 so that the first transmission member 322 can move between a first position and a second position.

[0097] The transmission assembly also includes a first protrusion 326, which is connected to the fourth transmission member 323. The third transmission member 3252 is provided with a second mating part 32511. The first protrusion 326 and the second mating part 32511 cooperate with each other so that the third transmission member 3252 can drive the fourth transmission member 323 to move.

[0098] As shown in Figures 17 to 22, when the first rocker arm 3113 is pulled, the first rocker arm 3113 can drive the second connecting arm 3111 to rotate through the first connecting arm 1. The second connecting arm 3111 can push the third transmission component 3252 to rotate. The third transmission component 3252 can drive the first protrusion 326 to rotate, so that the first protrusion 326 can drive the fourth transmission component 323 to move, thereby realizing the position control of the first transmission component 322.

[0099] By designing the fourth transmission component 323 and the first protrusion 326 to connect the third transmission component 3252 and the first transmission component 322, the force transmission path of the first transmission component 322 can be increased, facilitating the control of the position of the first transmission component 322. The fourth transmission component 323 can directly drive the first transmission component 322, or it can drive the first transmission component 322 through toothed meshing. The fourth transmission component 323 can be a rod-like structure, such as a slender, cylindrical, or curved shape, or it can be a plate-like structure or other irregular structures.

[0100] Optionally, the transmission assembly further includes a second drive source 324, which drives the fourth transmission member 323 to move, thereby causing the first transmission member 322 to move between a first position and a second position.

[0101] As shown in Figures 17 and 18, a second drive source 324 can be connected to a fourth transmission component 323. The second drive source 324 drives the fourth transmission component 323 to rotate bidirectionally around the seventh rotating shaft 007, thereby driving the first transmission component 322 to move between a first position and a second position. The second drive source 324 can be a motor, cylinder, or other drive component, and its bidirectional drive enables the fourth transmission component 323 to rotate bidirectionally around the seventh rotating shaft 007.

[0102] Optionally, the transmission assembly further includes a fifth transmission member 3251, one end of the third transmission member 3252 is connected to the fourth transmission member 323, the other end of the third transmission member 3252 is connected to the fifth transmission member 3251, and the fifth transmission member 3251 abuts against the second connecting arm 3111.

[0103] When the second connecting arm 3111 rotates, the fifth transmission component 3251 can rotate and drive the third transmission component 3252 to rotate.

[0104] As shown in Figures 19 to 22, one end of the third transmission member 3252 is connected to the fourth transmission member 323, and the other end of the third transmission member 3252 is connected to the fifth transmission member 3251. The fifth transmission member 3251 abuts against the second connecting arm 3111, thereby forming a force transmission path between the second connecting arm 3111, the fifth transmission member 3251, the third transmission member 3252, and the fourth transmission member 323. The fifth transmission member 3251 can be a rod-shaped structure, a plate-shaped structure, or other irregular structures. Power can be transmitted between the fifth transmission member 3251 and the third transmission member 3252.

[0105] When the first rocker arm 3113 is pulled, the first rocker arm 3113 can drive the second connecting arm 3111 to rotate through the first connecting arm 1. The second connecting arm 3111 can drive the fifth transmission component 3251 to rotate. The fifth transmission component 3251 can drive the third transmission component 3252 to rotate. The third transmission component 3252 can drive the first protrusion 326 to rotate, so that the first protrusion 326 can drive the fourth transmission component 323 to move, thereby realizing the position control of the first transmission component 322.

[0106] Optionally, the inner locking part 31 further includes a first driving arm 312 and a third connecting arm 3112. The third connecting arm 3112 has a second coupling position. When the third connecting arm 3112 is in the second coupling position, the second connecting arm 3111 can drive the first driving arm 312 to move through the third connecting arm 3112.

[0107] As shown in Figure 16, the first drive arm 312 and the third connecting arm 3112 are connected, enabling power transmission between them. As shown in Figures 4 and 5, when the third connecting arm 3112 is in the second coupling position, that is, when the third connecting arm 3112 is coupled with the second connecting arm 3111, the third connecting arm 3112 can transmit the force received from the second connecting arm 3111 to the first drive arm 312, facilitating the first drive arm 312 to drive the first transmission member 322 to move, thereby driving the locking arm 331 to move.

[0108] Optionally, the outer locking part 32 further includes a second rocker arm 321, one end of which is pushed by the first drive arm 312, and the second rocker arm 321 can drive the first transmission member 322 to move so as to drive the locking arm 331 to move.

[0109] As shown in Figure 8, the first drive arm 312 abuts against the bottom 3211 of the second rocker arm 321, so that the first drive arm 312 can drive the first transmission component 322 to rotate through the second rocker arm 321, thereby driving the locking arm 331 to move to decouple from the lock tongue 332 and realize the door lock unlocking.

[0110] Optionally, the third connecting arm 3112 has a second decoupling position, in which the second connecting arm 3111 cannot transmit power to the third connecting arm 3112.

[0111] As shown in Figures 6 and 7, when the third connecting arm 3112 is in the second decoupling position, that is, when the third connecting arm 3112 and the second connecting arm 3111 are decoupled, the third connecting arm 3112 cannot receive the force of the second connecting arm 3111, and the third connecting arm 3112 cannot transmit the force of the second connecting arm 3111 to the first driving arm 312. In other words, a force transmission path cannot be formed between the second connecting arm 3111, the third connecting arm 3112, the first driving arm 312, and the first transmission component 322.

[0112] When the third connecting arm 3112 is in the second decoupling position, the inner locking part 31 cannot drive the first transmission member 322. That is, the inner opening mechanism formed by the inner locking part 31 is locked and cannot be linked with the outer locking part 32. Even if a child pulls the inner opening mechanism from inside the passenger compartment, the door cannot be opened. This prevents accidents caused by children accidentally pulling the door lock structure and improves the safety of the door lock structure.

[0113] Optionally, the inner locking part 31 further includes a first lever 313 for driving the third connecting arm 3112 to move between a second decoupling position and a second coupling position.

[0114] As shown in Figures 4 to 6, the first lever 313 can be positioned on the third rotating shaft 003, meaning the first lever 313 can rotate around the third rotating shaft 003. Furthermore, the first lever 313 is positioned to abut against the third connecting arm 3112, so that when the first lever 313 rotates counterclockwise, it drives the third connecting arm 3112 to rotate clockwise and decouple it from the second connecting arm 3111. At this time, power cannot be transmitted between the second connecting arm 3111 and the third connecting arm 3112, preventing the inner locking part 31 from driving the first transmission member 322.

[0115] When the first lever 313 rotates clockwise, the third connecting arm 3112 can rotate counterclockwise and couple with the second connecting arm 3111. At this time, power can be transmitted between the second connecting arm 3111 and the third connecting arm 3112, so that the inner locking part 31 can drive the first transmission member 322.

[0116] In another embodiment, the first lever 313 can also be controlled to make translational movements through a mechanical structure, and the third connecting arm 3112 can also be driven to move between the second coupling position and the second decoupling position through the translational movements of the first lever 313.

[0117] The third connecting arm 3112 and the first lever 313 form a child lock structure. When the first lever 313 rotates counterclockwise, the third connecting arm 3112 decouples from the second connecting arm 3111, locking the inner opening mechanism and preventing it from engaging with the outer locking part 32. Even if a child pulls the inner opening mechanism from inside the passenger compartment, the door cannot be opened. When the first lever 313 rotates clockwise, the third connecting arm 3112 couples with the second connecting arm 3111, unlocking the inner opening mechanism and enabling it to engage with the outer locking part 32. Furthermore, the child lock structure consists only of the third connecting arm 3112 and the first lever 313, resulting in a simple structure that reduces the space occupied by the door lock structure and facilitates the miniaturization of the door lock structure.

[0118] Optionally, when the outer locking part 32 and the latch assembly 33 are coupled and the third connecting arm 3112 is in the second coupling position, the second connecting arm 3111 can drive the first driving arm 312 to move through the third connecting arm 3112. The first driving arm 312 can push the first transmission member 322 and unlock the latch assembly 33. In this way, a force transmission path of second connecting arm 3111 - third connecting arm 3112 - first driving arm 312 - first transmission member 322 - latch assembly 33 can be formed, and the unlocking function of the inner opening mechanism formed by the inner locking part 31 can be realized.

[0119] Optionally, it also includes a sixth transmission member 23, which is connected to a first drive source 21. The first drive source 21 is used to simultaneously drive the second transmission member 22 and the sixth transmission member 23. The sixth transmission member 23 is connected to a first prompting device, which is used to indicate the status of the inner locking part 31.

[0120] As shown in Figures 1 to 3, in this embodiment, the sixth transmission member 23 is connected to the output end of the first driving source 21 and can move under the drive of the first driving source 21. The door lock structure also includes a first prompting device, which includes, but is not limited to, a display device, an audio device, or other multimedia devices. Driven by the first driving source 21, the sixth transmission member 23 can connect to the first prompting device, thereby providing prompts for the locking and unlocking signals of the inner locking part 31, improving the reliability of the door lock structure. The sixth transmission member 23 can be a rod-shaped structure, such as a long, thin, cylindrical, or curved shape, or it can be a plate-shaped structure or other structures.

[0121] Optionally, the main body 4 is provided with a second prompting device 41, and the latch assembly 33 further includes a signal connecting arm 333. The signal connecting arm 333 is coaxially arranged with the latch 332 and axially connected. When the latch 332 rotates, the signal connecting arm 333 can connect with the second prompting device 41.

[0122] As shown in Figures 10, 14, and 15, the main body 4 is also provided with a second prompting device 41, which includes, but is not limited to, a display device, an audio device, or other multimedia devices. The signal connecting arm 333 is coaxially arranged and axially connected to the latch 332. For example, the latch 332 may have a third groove 3323, and the signal connecting arm 333 may have a fourth protrusion 3331 adapted to the third groove 3323. The fourth protrusion 3331 engages with the third groove 3323 to form a fit. Under the drive of the latch 332, the signal connecting arm 333 can connect to the second prompting device 41, thereby realizing the transmission of locking and unlocking signals of the latch assembly 33, and also improving the reliability of the door lock structure.

[0123] Optionally, the locking arm 331 includes a second protrusion 3312, and the first transmission member 322 in the first position is capable of pushing the second protrusion 3312 to move, thereby unlocking the latch assembly 33.

[0124] As shown in Figures 8 and 9, the locking arm 331 is provided with a second protrusion 3312. The first transmission member 322, located in the first position, corresponds at least partially to the second protrusion 3312, thereby facilitating the first transmission member 322 to drive the locking arm 331 to move in a coupled state. For example, when the second rocker arm 321 rotates clockwise, it can drive the first transmission member 322 to rotate clockwise as well, so that the first transmission member 322 can push the locking arm 331 to move counterclockwise, as shown in Figures 11 to 13, until the locking arm 331 is decoupled from the latch 332 and the lock is unlocked.

[0125] Optionally, the first transmission member 322 in the second position cannot transmit power to the second protrusion 3312.

[0126] When the first transmission member 322 is in the second position, it is decoupled from the locking arm 331. The first transmission member 322 cannot drive the locking arm 331 to move until it is decoupled from the bolt 332, meaning the door lock cannot be unlocked. At this time, neither the inner opening mechanism with the inner locking part 31 nor the outer opening mechanism with the outer locking part 32 can unlock the door. Therefore, the unlocking capabilities of the inner and outer opening mechanisms can be adjusted by controlling the switching member, thereby improving the security and reliability of the door lock structure.

[0127] Optionally, the first drive arm 312 is mounted on the second rotating shaft 002;

[0128] Alternatively, the first transmission component 322 is mounted on the fifth rotating shaft 005 and is able to rotate around the fifth rotating shaft 005;

[0129] Alternatively, the second rocker arm 321 is located on the fourth rotating shaft 004;

[0130] Alternatively, the fifth transmission component 3251 may be mounted on the eighth rotating shaft 008;

[0131] Alternatively, the third transmission component 3252 may be mounted on the ninth rotating shaft 009.

[0132] Alternatively, the bolt 332 can be mounted on the sixth pivot 006, and the locking arm 331 can be mounted on the fourth pivot 004. This allows the unlocking function to be achieved through the rotational design of each component of the door lock structure, and also facilitates the miniaturization and integration of the door lock structure.

[0133] This application also provides a vehicle, including a door and the aforementioned door lock structure, wherein the door lock structure is located on the inside of the door.

[0134] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
