[0071] Referring to the accompanying drawings, an embodiment of the present application provides a door lock structure, which can be used in vehicles, such as fuel vehicles, new energy electric vehicles, etc., and can realize the functions of opening and locking the vehicle doors.

[0072] The door lock structure comprises:

[0073] A locking tongue assembly 33, wherein the locking tongue assembly 33 comprises a locking arm 331 and a locking tongue 332;

[0074] The outer locking portion 32 includes a first transmission member 322, the first transmission member 322 can move between a first position and a second position, and the first transmission member 322 located at the first position can drive the locking arm 331 to move to decouple from the locking tongue 332, and the first transmission member 322 located at the second position cannot drive the locking arm 331 to move to decouple from the locking tongue 332;

[0075] The inner locking portion 31 includes a switch member and a transmission assembly that can be operated by a user, the switch member is connected to the first transmission member 322 through the transmission assembly, and when the transmission assembly is in a first transmission state, the switch member 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 a second transmission state, the switch member cannot drive the first transmission member 322 from the second position to the first position through the transmission assembly.

[0076] like Figures 11 to 13 As shown, the locking tongue assembly 33 of the utility model embodiment may include a locking arm 331 and a locking tongue 332. The locking tongue 332 may be arranged on the sixth rotating shaft 006 and can rotate around the sixth rotating shaft 006 under the drive of a locking ring (not shown). The locking arm 331 may be arranged 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 as to decouple the locking arm 331 from the locking tongue 332 and achieve unlocking.

[0077] Specifically, Figures 11 to 13 The figure shows the locking process. The locking tongue 332 rotates clockwise under the drive of the locking ring until the first groove 3321 on the locking tongue 332 abuts against the third protrusion 3311 on the locking arm 331, thereby realizing the first locking. The locking ring continues to drive the locking tongue 332 to rotate clockwise until the second groove 3322 on the locking tongue 332 abuts against the third protrusion 3311 on the locking arm 331, thereby realizing the second locking.

[0078] like Figure 8 and Fig. 9 The unlocking process is shown in FIG. 3. The locking arm 331 is provided with a second protrusion 3312, and the first transmission member 322 located at the first position at least partially corresponds to the second protrusion 3312, so that the first transmission member 322 can drive the locking arm 331 to move in the 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 ( Figures 11 to 13 ) until the locking arm 331 is decoupled from the locking tongue 332 and unlocking is achieved.

[0079] The first transmission member 322 may be a rod-shaped structure, such as a slender, cylindrical, curved or other shape, or a plate-shaped structure or other structure. Driven by the transmission assembly, the first transmission member 322 may move between the first position and the 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.

[0080] Specifically, the position control of the first transmission member 322 can be achieved through a switch member and a transmission assembly that can be manipulated by a user. The switch member can adjust the state of the transmission assembly through a mechanical structure or a signal, so that the transmission assembly can switch between a first transmission state and a second transmission state. The switch member includes but is not limited to a knob, a button, a pull rod, etc. that can be manipulated by a user. The transmission assembly includes one or more transmission members that transmit to each other.

[0081] When the transmission assembly is in the first transmission state, the switch member can drive the first transmission member 322 from the second position to the first position through the transmission assembly, that is, Fig.17 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 to decouple from the lock tongue 332, thereby unlocking the door lock. At this time, both the inner opening mechanism with the inner locking portion 31 and the outer opening mechanism with the outer locking portion 32 can unlock the door lock.

[0082] When the transmission assembly is in the second transmission state, the switch member cannot drive the first transmission member 322 from the second position to the first position through the transmission assembly. At this time, the first transmission member 322 is in the second position, that is, Fig.18 The first transmission member 322 is now decoupled from the locking arm 331, and the first transmission member 322 cannot drive the locking arm 331 to move to decouple from the lock tongue 332, that is, the door lock cannot be unlocked. At this time, the inner opening mechanism with the inner locking portion 31 and the outer opening mechanism with the outer locking portion 32 cannot unlock the door lock. In this way, the unlocking capabilities of the inner opening mechanism and the outer opening mechanism can be adjusted together through the control of the switch member, thereby simplifying the control of the door lock structure and facilitating the miniaturization of the door lock structure.

[0083] Optionally, the transmission assembly includes a first rocker arm 3113 and a second connecting arm 3111, the switch member is connected to the first rocker arm 3113, the first rocker arm 3113 can transmit power to the second connecting arm 3111, and the second connecting arm 3111 is used to drive the first transmission member 322 to move.

[0084] like Fig. 20 and Fig.21 As shown, the switch member can be connected to the first rocker arm 3113, so that the switch member 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-the first transmission member 322, thereby driving 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 lock tongue 332, thereby realizing unlocking the door lock.

[0085] Optionally, it further includes a first connecting arm 1, which can move 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;

[0086] When the first connecting arm 1 is placed 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 .

[0087] like Fig. 20 and Fig.21 As shown, 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, and the second connecting arm 3111 can drive the first transmission member 322 to move to the first position, so that the outer locking portion 32 is unlocked.

[0088] 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 cannot 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 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 is still in the second position, so that the outer locking portion 32 is locked.

[0089] Optionally, a first driving source 21 is further included, and the first driving source 21 can drive the first connecting arm 1 to move between a first decoupling position and a first coupling position.

[0090] like Figures 1 to 3 As shown, the first driving source 21 includes but is not limited to a motor, a cylinder, a worm gear and other structures, and the first driving source 21 is used to output a driving force to the first connecting arm 1. Driven by the first driving source 21, the first connecting arm 1 can move between a first decoupling position and a first coupling position. According to the specific structural design of the door lock structure, the movement of the first connecting arm 1 includes but is not limited to rotation and movement.

[0091] Optionally, it further includes a second transmission member 22, one end of the second transmission member 22 is connected to the first driving source 21, and the other end of the second transmission member 22 is connected to the first connecting arm 1;

[0092] Driven by the first driving source 21 , the first connecting arm 1 can move between a first coupling position and a first decoupling position.

[0093] like Figures 1 to 3 As shown, the first driving 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 driving source 21 to the connected first connecting arm 1. Driven by the first driving source 21, the second transmission member 22 can move and drive the first connecting arm 1 to move, so that the first connecting arm 1 can move between the first decoupling position and the first coupling position. Among them, the second transmission member 22 can be a rod-shaped structure, for example, slender, cylindrical, curved or other shapes, and the second transmission member 22 can also be a plate-shaped structure or other structures.

[0094] Optionally, the transmission assembly also includes a third transmission member 3252, one end of the third transmission member 3252 is connected to the second connecting arm 3111, and the other end of the third transmission member 3252 is connected to the first transmission member 322, and the third transmission member 3252 can drive the first transmission member 322 to move between the first position and the second position.

[0095] like Figures 17 to 22 As shown, the switch member can be connected to the first rocker arm 3113, so that the switch member can drive the first rocker arm 3113 to move, and can form a power transmission path between the first rocker arm 3113-the second connecting arm 3111-the third transmission member 3252-the first transmission member 322, thereby driving 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 to decouple from the lock tongue 332, thereby realizing unlocking the door lock.

[0096] By designing the third transmission member 3252 to connect the second connecting arm 3111 and the first transmission member 322, the force transmission path of the first transmission member 322 can be increased, so as to facilitate the control of the position of the first transmission member 322. The third transmission member 3252 can be a rod-shaped structure, such as a slender shape, a cylindrical shape, a curved shape, or other shapes. The third transmission member 3252 can also be a plate-shaped structure or other irregular structures.

[0097] Optionally, the transmission assembly further includes a fourth transmission member 323, wherein the fourth transmission member 323 is connected to the first transmission member 322, so that the first transmission member 322 can move between the first position and the second position;

[0098] 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 matching portion 32511. The first protrusion 326 and the second matching portion 32511 cooperate with each other so that the third transmission member 3252 can drive the fourth transmission member 323 to move.

[0099] like Figures 17 to 22 As shown, 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 member 3252 to rotate, and the third transmission member 3252 can drive the first protrusion 326 to rotate, so that the first protrusion 326 can drive the fourth transmission member 323 to move, thereby realizing the position control of the first transmission member 322.

[0100] By designing the fourth transmission member 323 and the first protrusion 326 to connect the third transmission member 3252 and the first transmission member 322, the force transmission path of the first transmission member 322 can also be increased, so as to facilitate the control of the position of the first transmission member 322. The fourth transmission member 323 can directly push the first transmission member 322 to move, and the fourth transmission member 323 can also drive the first transmission member 322 to move through toothed engagement. Among them, the fourth transmission member 323 can be a rod-shaped structure, such as a slender shape, a cylindrical shape, a curved shape, or other shapes. The fourth transmission member 323 can also be a plate-shaped structure or other irregular structures.

[0101] Optionally, the transmission assembly further includes a second driving source 324, and the second driving source 324 is used to drive the fourth transmission member 323 to move, so as to drive the first transmission member 322 to move between the first position and the second position.

The second driving source 324 can be a driving member such as a motor or a cylinder, and the bidirectional driving thereof can realize the bidirectional rotation of the fourth transmission member 323 around the seventh rotation axis 007.

[0103] 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;

[0104] When the second connecting arm 3111 rotates, the fifth transmission member 3251 can rotate and drive the third transmission member 3252 to rotate.

[0105] like Figures 19 to 22 As shown, 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, and the fifth transmission member 3251 is against the second connecting arm 3111, so as to form a force transmission path between the second connecting arm 3111-the fifth transmission member 3251-the third transmission member 3252-the fourth transmission member 323. The fifth transmission member 3251 may be a rod-shaped structure, or a plate-shaped structure or other irregular structures, and power can be transmitted between the fifth transmission member 3251 and the third transmission member 3252.

[0106] 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 fifth transmission member 3251 to rotate, the fifth transmission member 3251 can drive the third transmission member 3252 to rotate, and the third transmission member 3252 can drive the first protrusion 326 to rotate, so that the first protrusion 326 can drive the fourth transmission member 323 to move, thereby realizing the position control of the first transmission member 322.

[0107] Optionally, the inner locking portion 31 also includes a first driving arm 312 and a third connecting arm 3112, the third connecting arm 3112 has a second coupling position, and when the third connecting arm 3112 is located at the second coupling position, the second connecting arm 3111 can drive the first driving arm 312 to move through the third connecting arm 3112.

[0108] like Fig.16 As shown, the first driving arm 312 is connected to the third connecting arm 3112, so that power can be transmitted between the first driving arm 312 and the third connecting arm 3112. Figure 4 and Figure 5 As shown, when the third connecting arm 3112 is in the second coupling position, that is, the third connecting arm 3112 and the second connecting arm 3111 are in a coupled state, the third connecting arm 3112 can transfer the force received from the second connecting arm 3111 to the first driving arm 312, so that the first driving arm 312 can drive the first transmission member 322 to move to drive the locking arm 331 to move.

[0109] Optionally, the outer locking portion 32 further includes a second rocker arm 321 , one end of the second rocker arm 321 is used to be pushed by the first driving 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.

[0110] like Figure 8 As shown, the first driving arm 312 abuts against the bottom 3211 of the second rocker arm 321, so that the first driving arm 312 can drive the first transmission member 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 door unlocking.

[0111] Optionally, the third connecting arm 3112 has a second decoupling position. When the third connecting arm 3112 is located at the second decoupling position, the second connecting arm 3111 cannot transmit power to the third connecting arm 3112 .

[0112] like Figure 6 and Figure 7 As shown, when the third connecting arm 3112 is in the second decoupling position, that is, the third connecting arm 3112 and the second connecting arm 3111 are in a decoupling state, 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, that is, no force transmission path can be formed between the second connecting arm 3111-the third connecting arm 3112-the first driving arm 312-the first transmission member 322.

[0113] When the third connecting arm 3112 is in the second decoupling position, the inner locking portion 31 cannot drive the first transmission member 322. That is, the inner opening mechanism formed by the inner locking portion 31 is locked and cannot be linked with the outer locking portion 32. Even if a child pulls the inner opening mechanism in the passenger compartment, the door cannot be opened. This can prevent accidents caused by children pulling the door lock structure by mistake, thereby improving the safety of the door lock structure.

[0114] Optionally, the inner locking portion 31 further includes a first lever 313, and the first lever 313 is used to drive the third connecting arm 3112 to move between the second decoupling position and the second coupling position.

[0115] like Figures 4 to 6 As shown, the first lever 313 can be arranged on the third rotating shaft 003, that is, the first lever 313 can rotate around the third rotating shaft 003. In addition, the first lever 313 is arranged to abut against the third connecting arm 3112, so that when the first lever 313 rotates counterclockwise, it can drive the third connecting arm 3112 to rotate clockwise and decouple 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, so that the inner locking portion 31 cannot drive the first transmission member 322.

[0116] 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 portion 31 can drive the first transmission member 322 .

[0117] In another embodiment, the first lever 313 may be controlled to perform translational motion through a mechanical structure, and the third connecting arm 3112 may be driven to move between the second coupling position and the second decoupling position through the translational motion of the first lever 313 .

[0118] The third connecting arm 3112 and the first lever 313 can form a child lock structure. When the first lever 313 rotates counterclockwise, the third connecting arm 3112 is decoupled from the second connecting arm 3111, so that the inner opening mechanism is locked and cannot be linked with the outer locking part 32. Even if a child pulls the inner opening mechanism in the passenger compartment, the door cannot be opened. When the first lever 313 rotates clockwise, the third connecting arm 3112 is coupled with the second connecting arm 3111, so that the inner opening mechanism is unlocked and can be linked with the outer locking part 32. The child lock structure is only composed of the third connecting arm 3112 and the first lever 313, which has a simple structure, can reduce the space occupied by the door lock structure, and is also convenient for the miniaturization of the door lock structure.

[0119] Optionally, when the outer locking portion 32 and the bolt assembly 33 are in a coupled state, and the third connecting arm 3112 is in a second coupled position, the second connecting arm 3111 can drive the first driving arm 312 to move through the third connecting arm 3112, and the first driving arm 312 can push the first transmission member 322, and bring the bolt assembly 33 to an unlocked state. In this way, a force transmission path of the second connecting arm 3111-third connecting arm 3112-first driving arm 312-first transmission member 322-bolt assembly 33 can be formed, and the unlocking function of the inner opening mechanism formed by the inner locking portion 31 can be realized.

[0120] Optionally, it also includes a sixth transmission member 23, which is connected to the first driving source 21, and the first driving source 21 is used to simultaneously drive the second transmission member 22 and the sixth transmission member 23, and the sixth transmission member 23 is connected to a first prompting device, and the first prompting device is used to prompt the state of the inner locking part 31.

[0121] like Figures 1 to 3As shown, the embodiment of the utility model is provided with a sixth transmission member 23 connected to the output end of the first driving source 21, and can move under the drive of the first driving source 21. A first prompting device is also provided on the door lock structure, and the first prompting device includes but is not limited to a display device, an audio device or other multimedia devices. Under the drive of the first driving source 21, the sixth transmission member 23 can be connected to the first prompting device, so as to realize the prompting of the locking signal and the unlocking signal of the inner locking part 31, thereby improving the reliability of the door lock structure. Among them, the sixth transmission member 23 can be a rod-shaped structure, for example, in other shapes such as slender, cylindrical, curved, etc., and the sixth transmission member 23 can also be a plate-shaped structure or other structures.

[0122] Optionally, a second prompting device 41 is provided on the main body 4, and the lock tongue assembly 33 also includes a signal connecting arm 333, which is coaxially arranged and axially connected to the lock tongue 332. When the lock tongue 332 rotates, the signal connecting arm 333 can be connected to the second prompting device 41.

[0123] like Fig.10 , Fig.14 and Fig.15 As shown, the body 4 is also provided with a second prompting device 41, and the second prompting device 41 includes but is not limited to a display device, an audio device or other multimedia devices. The signal connecting arm 333 is coaxially arranged with the lock tongue 332 and axially connected. For example, the lock tongue 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, and the fourth protrusion 3331 is engaged with the third groove 3323 to form a match. Under the drive of the lock tongue 332, the signal connecting arm 333 can be connected to the second prompting device 41, thereby realizing the transmission of the locking signal and the unlocking signal of the lock tongue assembly 33, and also improving the reliability of the door lock structure.

[0124] Optionally, the locking arm 331 includes a second protrusion 3312 , and the first transmission member 322 located at the first position can push the second protrusion 3312 to move, so that the locking tongue assembly 33 is unlocked.

[0125] like Figure 8 and Fig. 9 As shown, the locking arm 331 is provided with a second protrusion 3312, and the first transmission member 322 located at the first position at least partially corresponds to the second protrusion 3312, so that the first transmission member 322 can drive the locking arm 331 to move in the 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, see Figures 11 to 13 , until the locking arm 331 and the locking tongue 332 are decoupled and unlocking is achieved.

[0126] Optionally, the first transmission member 322 located at the second position cannot transmit power to the second protrusion 3312 .

[0127] When the first transmission member 322 is in the second position, the first transmission member 322 is decoupled from the locking arm 331, and the first transmission member 322 cannot drive the locking arm 331 to move to decouple from the lock tongue 332, that is, the door lock cannot be unlocked. At this time, the inner opening mechanism with the inner locking portion 31 and the outer opening mechanism with the outer locking portion 32 cannot unlock the door lock. In this way, the unlocking capabilities of the inner opening mechanism and the outer opening mechanism can be adjusted by controlling the switch member, thereby improving the safety and reliability of the door lock structure.

[0128] Optionally, the first driving arm 312 is disposed on the second rotating shaft 002;

[0129] Alternatively, the first transmission member 322 is disposed on the fifth rotating shaft 005 and is capable of rotating around the fifth rotating shaft 005;

[0130] Alternatively, the second rocker arm 321 is disposed on the fourth rotating shaft 004;

[0131] Alternatively, the fifth transmission member 3251 is disposed on the eighth rotating shaft 008;

[0132] Alternatively, the third transmission member 3252 is disposed on the ninth rotating shaft 009.

[0133] Alternatively, the locking tongue 332 is disposed on the sixth rotating shaft 006, and the locking arm 331 is disposed on the fourth rotating shaft 004. In this way, the rotation design of each component of the door lock structure can be used to realize the unlocking function, which is also convenient for the miniaturization and integration development of the door lock structure.

[0134] An embodiment of the present application also provides a vehicle, comprising a vehicle door and the above-mentioned door lock structure, wherein the door lock structure is arranged on the inner side of the vehicle door.
