[0066] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0070] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0072] 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.

[0073] like Figures 4 to 6 As shown, the door lock structure includes:

[0074] An unlocking component, when the unlocking component is in a working state, the door lock can be opened;

[0075] The inner locking portion 31 includes a second connecting arm 3111 and a third connecting arm 3112. When the third connecting arm 3112 is in the coupling position, it can transfer the force of the second connecting arm 3111 to the unlocking component so that the unlocking component can be in a working state; when the third connecting arm 3112 is in the decoupling position, the third connecting arm 3112 cannot transfer the force of the second connecting arm 3111 to the unlocking component.

[0076] The unlocking component is used to perform the unlocking function. The unlocking component may include a set of components, and use the set of components to achieve unlocking; the unlocking component may also include multiple sets of components that drive each other, and use these mutually driving components to achieve unlocking. When the unlocking component is in a working state, the unlocking component can unlock so that the door lock opens, and the unlocking component can also lock so that the door lock cannot be opened.

[0077] Specifically, the third connecting arm 3112 has a coupling position and a decoupling position. Figure 4 , Figure 5 and Figure 7 As shown, when the third connecting arm 3112 is in the 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 unlocking component, that is, a force transmission path can be formed between the second connecting arm 3111-the third connecting arm 3112-the unlocking component, so that the unlocking component can be in a working state.

[0078] like Figure 6 As shown, when the third connecting arm 3112 is in the decoupled position, that is, the third connecting arm 3112 and the second connecting arm 3111 are in a decoupled 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 unlocking component, that is, no force transmission path can be formed between the second connecting arm 3111-the third connecting arm 3112-the unlocking component.

[0079] When the third connecting arm 3112 is in the decoupled position, the inner locking portion 31 cannot drive the unlocking component. That is, the inner opening mechanism formed by the inner locking portion 31 is locked and cannot be linked with the unlocking component. 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.

[0080] Furthermore, by controlling the position of the third connecting arm 3112, the power transmission from the inner locking part 31 to the unlocking part can be controlled, so that the child lock function can be conveniently realized, which is convenient for reducing the space occupied by the door lock structure and facilitating the miniaturization of the door lock structure.

[0081] Optionally, the inner locking portion 31 further includes a first lever 313 , and the first lever 313 can drive the third connecting arm 3112 to move between a coupling position and a decoupling position.

[0082] like Figures 4 to 6As 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 part 31 cannot drive the unlocking component.

[0083] 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 unlocking part.

[0084] 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 coupling position and the decoupling position through the translational motion of the first lever 313 .

[0085] 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 unlocking component. 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 unlocking component. 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.

[0086] Optionally, one end of the third connecting arm 3112 abuts against the second connecting arm 3111 , and the other end of the third connecting arm 3112 abuts against the first shifting rod 313 .

[0087] Specifically, the two ends of the third connecting arm 3112 are respectively arranged to abut against the second connecting arm 3111 and the first lever 313, so that when the first lever 313 moves, the first lever 313 can drive the third connecting arm 3112 to move accordingly, and couple and decouple with the second connecting arm 3111, thereby realizing the locking of the inner opening structure.

[0088] Alternatively, if Figures 4 to 6As shown, the first lever 313 is arranged on the third rotating shaft 003, and the third connecting arm 3112 is arranged on the tenth rotating shaft 0010. When the first lever 313 rotates, the first lever 313 can push the third connecting arm 3112 to rotate to the decoupling position, thereby realizing the control of the power transmission of the inner locking part 31-the unlocking part.

[0089] Optionally, a first connecting arm 1 is further included, and the inner locking portion 31 further includes a first rocker arm 3113, and the first connecting arm 1 has a first position and a second position;

[0090] When the first connecting arm 1 is in the first position, the first connecting arm 1 and the first rocker arm 3113 are in a coupled state, and the first rocker arm 3113 can drive the first connecting arm 1 to move when it moves, and drive the second connecting arm 3111 to move through the first connecting arm 1;

[0091] When the first connecting arm 1 is in the second position, the first connecting arm 1 and the first rocker arm 3113 are in a decoupled state, and the first rocker arm 3113 cannot drive the first connecting arm 1 to move when it moves.

[0092] like Figure 1 and Figure 2 As shown, the first connecting arm 1 can be arranged on the first rotating shaft 001, and the first connecting arm 1 can move radially around the first rotating shaft 001 under the drive of the driving source to switch between the first position and the second position. For example, under the positive drive of the driving source, the first connecting arm 1 can move from the first position to the second position; under the reverse drive of the driving source, the first connecting arm 1 can move from the second position to the first position.

[0093] like Figure 1 As shown, when the first connecting arm 1 rotates to the first 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 first connecting arm 1 to move, the first connecting arm 1 can drive the second connecting arm 3111 to move, the second connecting arm 3111 drives the third connecting arm 3112 to move, and the third connecting arm 3112 can transmit the force received from the second connecting arm 3111 to the unlocking component, that is, a force transmission path is formed between the first rocker arm 3113-first connecting arm 1-second connecting arm 3111-third connecting arm 3112-unlocking component, so that the unlocking component can be in a working state.

[0094] Furthermore, when the first connecting arm 1 drives the second connecting arm 3111 to move, the fourth transmission member 322 can be reset to the third position, so that the inner locking portion 31 can drive the bolt assembly 33 to open the door through the fourth transmission member 322. That is, the fourth transmission member 322 can be reset by the rotation of the second connecting arm 3111, so that the inner locking portion 31 is unlocked.

[0095] like Figure 2 As shown, when the first connecting arm 1 rotates to the second 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 first connecting arm 1 to move, and the first connecting arm 1 cannot drive the second connecting arm 3111 to move, so that the second connecting arm 3111 cannot drive the third connecting arm 3112 to move, and the third connecting arm 3112 cannot transmit the force of the second connecting arm 3111 to the unlocking component, that is, no force transmission path can be formed between the first rocker arm 3113-first connecting arm 1-second connecting arm 3111-third connecting arm 3112-unlocking component.

[0096] Optionally, it further includes a first driving source 21 and a first transmission member 22, one end of the first transmission member 22 is connected to the first driving source 21, and the other end of the first transmission member 22 is connected to the first connecting arm 1;

[0097] Driven by the first driving source 21 , the first transmission member 22 drives the first connecting arm 1 to move between the first position and the second position.

[0098] like Figures 1 to 3 As shown, the first driving source 21 includes but is not limited to structures such as a motor, a cylinder, a worm gear, etc. The first driving source 21 is used to output a driving force to the first transmission member 22. The first 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 first transmission member 22 can move linearly and drive the first connecting arm 1 to move, so that the first connecting arm 1 can move between the first position and the second position. Among them, the first transmission member 22 can be a rod-shaped structure, for example, in other shapes such as slender, cylindrical, curved, etc., and the first transmission member 22 can also be a plate-shaped structure or other structures.

[0099] Optionally, it also includes a second transmission member 23, which is connected to the first driving source 21, and the first driving source 21 is used to simultaneously drive the first transmission member 22 and the second transmission member 23, and the second 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.

[0100] like Figures 1 to 3 As shown, the embodiment of the utility model is provided with a second 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 second 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 second transmission member 23 can be a rod-shaped structure, for example, in other shapes such as slender, cylindrical, curved, etc., and the second transmission member 23 can also be a plate-shaped structure or other structures.

[0101] 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.

[0102] 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 second protrusion 3331 adapted to the third groove 3323, and the second 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.

[0103] Optionally, the first connecting arm 1 is arranged on the first rotating shaft 001, and the first connecting arm 1 can rotate around the first rotating shaft 001 and switch between the first position and the second position, thereby realizing the switching of the coupling state and the decoupling state between the first connecting arm 1 and the second connecting arm 3111.

[0104] Optionally, the first rocker arm 3113 can be driven by the second driving source. Under the drive of the second driving source, the first rocker arm 3113 can move and drive the first connecting arm 1 to move, and the first connecting arm 1 can sequentially drive the second connecting arm 3111 and the third connecting arm 3112 to move, so that the third connecting arm 3112 can drive the unlocking component. The second driving source includes but is not limited to a knob, a button, a pull rod, etc. that can be manipulated by a user.

[0105] Optionally, the unlocking component includes a lock tongue assembly 33 and an outer locking portion 32, and the lock tongue assembly 33 is used to control the opening and closing of the vehicle door;

[0106] When the third connecting arm 3112 is in the coupling position, the second connecting arm 3111 can drive the outer locking portion 32 to move through the third connecting arm 3112 , and drive the locking tongue assembly 33 to an unlocked state through the outer locking portion 32 .

[0107] Specifically, when the third connecting arm 3112 is in the decoupled position, the second connecting arm 3111 cannot drive the outer locking part 32 to move through the third connecting arm 3112, that is, the inner opening mechanism formed by the inner locking part 31 is locked and cannot be linked with the unlocking component, so that 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.

[0108] Optionally, the inner locking portion 31 also includes a first driving arm 312, which is connected to the third connecting arm 3112, and the end of the first driving arm 312 is used to abut against the outer locking portion 32. The third connecting arm 3112 can drive the outer locking portion 32 to move through the first driving arm 312, and drive the lock tongue assembly 33 to move to an unlocked state through the outer locking portion.

[0109] Specifically, Figure 4 , Figure 5 , Figure 8 and Fig.16 As shown, when the third connecting arm 3112 is in the coupling position, the third connecting arm 3112 is coupled with the second connecting arm 3111. By pulling the second connecting arm 3111, the third connecting arm 3112 can drive the first driving arm 312 to move. The bottom 3211 of the first driving arm 312 abuts against the outer locking portion 32, so that the first driving arm 312 can push the outer locking portion 32 to move, and drive the lock tongue assembly 33 to move to the unlocked state, thereby realizing the function of opening the vehicle door using the door lock structure.

[0110] Optionally, when the lock tongue assembly 33 and the outer locking part 32 are in a coupled state, and the third connecting arm 3112 is in a 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 outer locking part 32 and bring the lock tongue assembly 33 to an unlocked state. In this way, a force transmission path of the inner locking part 31-the outer locking part 32-the lock tongue assembly 33 can be formed, and the unlocking function of the inner opening mechanism formed by the inner locking part 31 can be realized.

[0111] Optionally, the outer locking portion 32 includes a third transmission member 323 and a fourth transmission member 322, the third transmission member 323 is connected to one end of the fourth transmission member 322, the third transmission member 323 can drive the fourth transmission member 322 to move when the third transmission member 323 moves, and the fourth transmission member 322 has a third position and a fourth position;

[0112] When the fourth transmission member 322 is in the third position, the fourth transmission member 322 and the lock tongue assembly 33 are in a coupled state; when the fourth transmission member 322 is in the fourth position, the fourth transmission member 322 and the lock tongue assembly 33 are in a decoupled state.

[0113] like Figure 8 , Fig.17 and Fig.18 As shown, the fourth transmission member 322 can be arranged on the fifth rotating shaft 005 and can rotate around the fifth rotating shaft 005, the third transmission member 323 can be arranged on the seventh rotating shaft 007 and can rotate around the seventh rotating shaft 007, and the third transmission member 323 is connected to the fourth transmission member 322, so that when the third transmission member 323 moves, it can drive the fourth transmission member 322 to move and switch between the third position and the fourth position. In this way, the unlocking and locking of the inner opening mechanism can be realized through the central control, further improving the reliability of the door lock structure.

[0114] like Fig.17 The figure shows a schematic diagram of a central control unlocking state. When the fourth transmission member 322 moves to the third position, the other end of the fourth transmission member 322 is coupled to the lock tongue assembly 33, so that when the fourth transmission member 322 rotates, it can drive the lock tongue assembly 33 to rotate to the unlocking state.

[0115] like Fig.18 The figure shows a schematic diagram of a central control locking state. When the fourth transmission member 322 moves to the fourth position, the other end of the fourth transmission member 322 is decoupled from the lock tongue assembly 33, so that the rotation trajectory of the fourth transmission member 322 is out of the unlocking range of the lock tongue assembly 33, that is, the rotation of the fourth transmission member 322 cannot drive the lock tongue assembly 33 to the unlocking state.

[0116] The third transmission member 323 may be a rod-shaped structure, such as a slender, cylindrical, curved or other shape, or a plate-shaped structure or other structure. The fourth 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. Power transmission can be performed between the third transmission member 323 and the fourth transmission member 322.

[0117] Optionally, the locking tongue assembly 33 includes a locking arm 331 and a locking tongue 332, the locking arm 331 being provided with a protrusion, and the fourth transmission member 322 located at the third position at least partially corresponds to the protrusion, so that the movement of the fourth transmission member 322 can drive the locking arm 331 to move until it is decoupled from the locking tongue 332; the movement of the fourth transmission member 322 located at the fourth position cannot drive the locking arm 331 to move.

[0118] 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 is arranged 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 is arranged on the fourth rotating shaft 004 and can rotate around the fourth rotating shaft 004 under the drive of the fourth transmission member 322, so that the locking arm 331 is decoupled from the locking tongue 332 and unlocking is achieved.

[0119] 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 first 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 first protrusion 3311 on the locking arm 331, thereby realizing the second locking.

[0120] like Figure 8 and Fig. 9 The unlocking process is shown in FIG. The locking arm 331 is provided with a protrusion, such as Fig. 9 In the circled area, the fourth transmission member 322 located at the third position at least partially corresponds to the protrusion, so that the fourth 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 fourth transmission member 322 to rotate clockwise as well, so that the fourth transmission member 322 can push the locking arm 331 to move counterclockwise, that is, Figures 11 to 13 , until the locking arm 331 and the locking tongue 332 are decoupled and unlocking is achieved.

[0121] Optionally, the fourth transmission member 322 is disposed on the fifth rotating shaft 005 and can rotate around the fifth rotating shaft 005. The rotation of the fourth transmission member 322 located at the third position can drive the locking arm 331 to move to a decoupled state with the locking tongue 332, thereby achieving unlocking.

[0122] Optionally, the outer locking portion 32 also includes a second rocker arm 321, and the second rocker arm 321 is connected to the end of the fourth transmission member 322, the second rocker arm 321 is used to transmit power to the fourth transmission member 322, and the second rocker arm 321 can drive the fourth transmission member 322 to rotate when it rotates.

[0123] like Figure 8 and Fig. 9 As shown, the outer locking part 32 of the present invention may include a second rocker arm 321, which may be connected to the outer door handle of the vehicle. The passenger may drive the outer door handle outside the vehicle passenger compartment and transmit the drive to the lock tongue assembly 33 to unlock the door. Figure 8 As shown, the bottom 3211 of the second rocker arm 321 abuts against the first driving arm 312 .

[0124] Specifically, the second rocker arm 321 can be arranged on the fourth rotating shaft 004 and can rotate around the fourth rotating shaft 004, and the fixed end of the second rocker arm 321 is connected to the end of the fourth transmission member 322, so that when the second rocker arm 321 rotates, it can drive the fourth transmission member 322 to rotate as well, and then the fourth transmission member 322 in the third position can drive the lock tongue assembly 33 to rotate to the unlocked state.

[0125] Optionally, the outer locking portion 32 further includes a third driving source 324, and the third driving source 324 is connected to the third transmission member 323;

[0126] Under the bidirectional drive of the third driving source 324 , the third transmission member 323 can move bidirectionally and drive the fourth transmission member 322 to move between the third position and the fourth position.

[0127] like Fig.17 and Fig.18 As shown, a third driving source 324 can be provided to be connected to the third transmission member 323, and the third driving source 324 can be used to drive the third transmission member 323 to rotate bidirectionally around the seventh rotation axis 007, thereby driving the fourth transmission member 322 to move between the third position and the fourth position. The third driving source 324 can be a driving member such as a motor or a cylinder, and the bidirectional drive thereof can realize the bidirectional rotation of the third transmission member 323 around the seventh rotation axis 007.

[0128] Optionally, the outer locking portion 32 further includes a third driving source 324 and a reset assembly 325, and the third driving source 324 and the reset assembly 325 are respectively connected to the third transmission member 323;

[0129] Under the drive of the third driving source 324, the third transmission member 323 can move along the first direction and drive the fourth transmission member 322 to move from the third position to the fourth position;

[0130] Driven by the reset assembly 325 , the third transmission member 323 can move in a direction opposite to the first direction, and drive the fourth transmission member 322 to move from the fourth position to the third position.

[0131] like Figures 17 to 22 As shown, the third driving source 324 and the reset assembly 325 can also be used to drive the third transmission member 323 to rotate bidirectionally around the seventh rotation axis 007, thereby driving the fourth transmission member 322 to move between the third position and the fourth position, so as to facilitate the implementation of central control and improve the controllability of the door lock structure.

[0132] For example, under the drive of the third driving source 324, the third transmission member 323 can rotate along the first direction and drive the fourth transmission member 322 to move from the third position to the fourth position. Fig.18 At this time, the other end of the fourth transmission member 322 is decoupled from the bolt assembly 33, so that when the second rocker arm 321 rotates, although it can drive the fourth transmission member 322 to rotate, due to the decoupling of the fourth transmission member 322 and the bolt assembly 33, the fourth transmission member 322 cannot drive the bolt assembly 33 to rotate to the unlocked state.

[0133] Under the drive of the reset assembly 325, the third transmission member 323 rotates in a direction opposite to the first direction, and drives the fourth transmission member 322 to move from the fourth position to the third position. Fig.17 At this time, the other end of the fourth transmission member 322 is coupled to the lock tongue assembly 33, so that when the second rocker arm 321 rotates, the fourth transmission member 322 can also be driven to rotate, and then the fourth transmission member 322 drives the lock tongue assembly 33 to rotate to the unlocked state.

[0134] Optionally, the reset assembly 325 includes a fifth transmission member 3251 and a sixth transmission member 3252, wherein the fifth transmission member 3251 is disposed on the eighth rotating shaft 008, and the sixth transmission member 3252 is disposed on the ninth rotating shaft 009, one end of the sixth transmission member 3252 is connected to the third transmission member 323, and the other end of the sixth transmission member 3252 is connected to the fifth transmission member 3251, and the fifth transmission member 3251 is against the second connecting arm 3111;

[0135] When the second connecting arm 3111 rotates, the fifth transmission member 3251 can rotate and drive the sixth transmission member 3252 to rotate, so that the third transmission member 323 moves in a direction opposite to the first direction.

[0136] like Figures 17 to 22As shown, the reset assembly 325 may include a fifth transmission member 3251 and a sixth transmission member 3252, wherein the fifth transmission member 3251 is disposed on the eighth rotating shaft 008 and can rotate around the eighth rotating shaft 008, and the sixth transmission member 3252 is disposed on the ninth rotating shaft 009 and can rotate around the ninth rotating shaft 009. The rotation of the fifth transmission member 3251 and the sixth transmission member 3252 can drive the third transmission member 323 to rotate in a direction opposite to the first direction, so that the third transmission member 323 can drive the fourth transmission member 322 to move from the fourth position to the third position. At this time, the other end of the fourth transmission member 322 is coupled to the bolt assembly 33, so that when the second rocker arm 321 rotates, the fourth transmission member 322 can also rotate, and then the fourth transmission member 322 can drive the bolt assembly 33 to rotate to the unlocked state.

[0137] Specifically, Figures 19 to 22 As shown, one end of the sixth transmission member 3252 is connected to the third transmission member 323, and the other end of the sixth transmission member 3252 is connected to the fifth transmission member 3251, and the fifth transmission member 3251 is abutted against the second connecting arm 3111 to form a force transmission path between the second connecting arm 3111-the fifth transmission member 3251-the sixth transmission member 3252-the third transmission member 323.

[0138] Among them, the fifth transmission member 3251 can be a rod-shaped structure, the fifth transmission member 3251 can also be a plate-shaped structure or other irregular structures; the sixth transmission member 3252 can be a rod-shaped structure, the sixth transmission member 3252 can also be a plate-shaped structure or other irregular structures, and power can be transmitted between the fifth transmission member 3251 and the sixth transmission member 3252.

[0139] Among them, Fig.19 As shown, the sixth transmission member 3252 has a first mounting portion 32521 and a second mounting portion 32522, the first mounting portion 32521 is used to form a match with the first matching portion 3231 on the third transmission member 323, and the second mounting portion 32522 is used to form a match with the second matching portion 32511 on the fifth transmission member 3251, so as to form a force transmission path between the second connecting arm 3111-the fifth transmission member 3251-the sixth transmission member 3252-the third transmission member 323. Among them, one of the mounting portion and the matching portion can be a groove, and the other of the mounting portion and the matching portion can be a matching protrusion to form a snap fit.

[0140] like Fig.17As shown, when the second connecting arm 3111 rotates (for example, pulling the first rocker arm 3113), the second connecting arm 3111 can push the fifth transmission member 3251 to rotate clockwise, the rotation of the fifth transmission member 3251 can drive the sixth transmission member 3252 to rotate clockwise, and the rotation of the sixth transmission member 3252 can drive the third transmission member 323 to rotate in a direction opposite to the first direction, so that the fourth transmission member 322 returns to the third position.

[0141] Optionally, when the second connecting arm 3111 rotates, the fourth transmission member 322 can be reset to the third position, so that the inner locking portion 31 can drive the bolt assembly 33 to open the door through the fourth transmission member 322. That is, the fourth transmission member 322 can be reset by the rotation of the second connecting arm 3111, so that the inner locking portion 31 is unlocked.

[0142] 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.
