[0029] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0030] FIG1 is a schematic diagram of the structure of the door lock device in an embodiment of the present application. FIG2 is a schematic diagram of the structure of the door lock device in FIG1 in another state. FIG3 is a schematic diagram of the three-dimensional structure decomposition of the door lock device in FIG1. ​​As shown in FIG1 to FIG3, the present application provides a vehicle, which includes a vehicle door and a door lock device 100, and the door lock device 100 is fastened to the vehicle door by bolts. The door lock device 100 provided in the embodiment of the present application is applied to a vehicle, which may specifically be a fuel vehicle or a new energy electric vehicle, and the door lock device 100 can realize the functions of opening and locking the vehicle door.

[0031] The door lock device 100 includes a connecting rod structure 11, a push rod 12, a locking arm, and a lock tongue. The connecting rod structure 11 pulls the push rod 12, which abuts the locking arm, which then engages the lock tongue. The connecting rod structure 11 has an unlocked position and a locked position. The user can activate a second transmission member 52 using a vehicle key or remote control, which abuts the connecting rod structure 11, driving the connecting rod structure 11 to switch between the unlocked position and the locked position. When the connecting rod structure 11 switches from the unlocked position to the locked position, the connecting rod structure 11 pulls the push rod 12 to move, releasing the abutment between the push rod 12 and the locking arm. At this point, the user cannot open the vehicle door by actuating the interior or exterior handle. When the connecting rod structure 11 switches from the locked position to the unlocked position, the connecting rod structure 11 pulls the push rod 12 in the opposite direction, abutting the locking arm. At this point, the user can open the vehicle door by actuating the interior or exterior handle.

[0032] The door lock device 100 also includes an outward opening rocker 13 and a mating rocker arm 14. The outward opening rocker 13 is connected to the vehicle's outward opening handle and is connected to the mating rocker arm 14 via a pin. When the connecting rod structure 11 is in the unlocked position, the outward opening handle is actuated by the user, which rotates the outward opening rocker 13, which in turn rotates the mating rocker arm 14. The mating rocker arm 14 rotates the push rod 12, which in turn rotates the locking arm. This disengages the locking arm and the deadbolt, allowing the vehicle door to open.

[0033] The door lock device 100 also includes an inner opening rocker 15 and a first rocker arm 21. The inner opening rocker 15 is connected to the vehicle's inner opening handle and abuts the first rocker arm 21, which in turn abuts the mating rocker arm 14. When the linkage structure 11 is in the unlocked position, if the user actuates the inner opening handle, the inner opening rocker 15 rotates, which in turn drives the first rocker arm 21, which in turn drives the mating rocker arm 14. The mating rocker arm 14 rotates the push rod 12, which in turn drives the locking arm, releasing the engagement between the locking arm and the deadbolt, and the vehicle door opens.

[0034] The door lock device 100 also includes a second rocker arm 22, a locking pin 23, and a locking link 24. Specifically, the first rocker arm 21 is a sheet-like structure, the second rocker arm 22 is a sheet-like structure, the first rocker arm 21 and the second rocker arm 22 are arranged opposite to each other with a distance therebetween, the locking pin 23 is arranged between the first rocker arm 21 and the second rocker arm 22, and the opposite ends of the locking pin 23 are respectively passed through the first rocker arm 21 and the second rocker arm 22. The first rocker arm 21 and the second rocker arm 22 are both rotationally connected to the locking pin 23, and the locking pin 23 can move relative to the first rocker arm 21 and the second rocker arm 22. Rotational connection is relative to fixed connection. The rotational connection between the first rocker arm 21 and the second rocker arm 22 and the locking pin 23 means that the first rocker arm 21 and the second rocker arm 22 are connected by the locking pin 23, and the first rocker arm 21 and the second rocker arm 22 can rotate relative to each other.

[0035] The locking pin 23 includes a first penetration portion 231 and a second penetration portion 232 at opposite ends thereof, and a connecting portion 233 connecting the first penetration portion 231 and the second penetration portion 232. The first penetration portion 231, the second penetration portion 232, and the connecting portion 233 are integrally formed. The connecting portion 233 is clamped between the first rocker arm 21 and the second rocker arm 22. The first penetration portion 231 penetrates the first rocker arm 21, and the second penetration portion 232 penetrates the second rocker arm 22. The first penetration portion 231, the second penetration portion 232, and the connecting portion 233 are cylindrical in shape. The radial dimension of the connecting portion 233 is larger than the radial dimensions of the first penetration portion 231 and the second penetration portion 232. The locking pin 23 can move in a direction perpendicular to the thickness of the first rocker arm 21 and the second rocker arm 22, but cannot move in the thickness direction of the first rocker arm 21 and the second rocker arm 22. The first rocker arm 21 includes two opposing outer surfaces, and the thickness direction of the first rocker arm 21 is a direction perpendicular to the two outer surfaces. The thickness direction of the second rocker arm 22 can be explained with reference to the thickness direction of the first rocker arm 21.

[0036] The first rocker arm 21 is provided with a driving groove 213. The edge of the first rocker arm 21 is recessed inward toward the locking pin 23 to form the driving groove 213. The first penetrating portion 231 of the locking pin 23 is penetrated in the driving groove 213. The first penetrating portion 231 of the locking pin 23 can also be detached from the driving groove 213.

[0037] The second rocker arm 22 is provided with a waist-shaped hole 221, which extends through the second rocker arm 22. The second penetration portion 232 of the locking pin 23 is penetrated by the waist-shaped hole 221, and the locking pin 23 can move along the long axis of the waist-shaped hole 221. When the second penetration portion 232 of the locking pin 23 moves from the upper end of the waist-shaped hole 221 to the lower end of the waist-shaped hole 221, the first penetration portion 231 of the locking pin 23 moves to the driving groove 213. When the second penetration portion 232 of the locking pin 23 moves from the lower end of the waist-shaped hole 221 to the upper end of the waist-shaped hole 221, the first penetration portion 231 of the locking pin 23 disengages from the driving groove 213. The long axis can be explained as follows. For example, the long axis of an ellipse refers to the line connecting the two points on the ellipse that are farthest apart. The cross-section of the waist-shaped hole 221 of the present application is formed by two parallel lines of equal length and two circular arcs. The movement of the long axis of the waist-shaped hole 221 can be explained by referring to the long axis of an ellipse. For example, the direction of the line connecting the upper and lower ends of the waist-shaped hole, i.e., the long axis of the waist-shaped hole, is perpendicular to the thickness direction of the first rocker arm and the second rocker arm.

[0038] The locking link 24 has a connecting slot 240, through which the connecting rod structure 11 is inserted. The second rocker arm 22 abuts the locking link 24, which drives the connecting rod structure 11 to rotate, switching the connecting rod structure 11 from the locked position to the unlocked position. The locking link 24 and the connecting rod structure 11 switch between the unlocked and locked positions synchronously. The locking link 24 includes a first connecting rod 241 and a second connecting rod 242. The first connecting rod 241 and the second connecting rod 242 are fixedly connected. The first connecting rod 241 is configured to abut the second rocker arm 22, and the connecting slot 240 is defined in the second connecting rod 242.

[0039] As shown in Figure 1, when the first penetration portion 231 of the locking pin 23 is penetrated by the driving groove 213, the first rocker arm 21 and the second rocker arm 22 are connected, and the first rocker arm 21 drives the second rocker arm 22 to rotate through the locking pin 23. The second rocker arm 22 abuts against the first link 241 of the locking link 24 to rotate, and the second link 242 of the locking link 24 drives the link structure 11 to rotate. The locking link 24 and the link structure 11 are in the unlocked position, and the door lock device 100 is in the unlocked state. The user drives the inner opening handle or the outer opening handle, thereby driving the matching rocker arm 14 to open the car door.

[0040] As shown in Figure 2, when the locking pin 23 disengages from the drive slot 213, the locking pin 23 and the first rocker arm 21 are released from the fixed state, that is, the movements of the first rocker arm 21 and the locking pin 23 are relatively independent, the first rocker arm 21 is driven, the second rocker arm 22 does not rotate, the locking link 24 is not driven by external force, the locking link 24 is in the locked position, the door lock device 100 is in the locked state, and when the user drives the inner opening handle or the outer opening handle, the car door cannot be opened.

[0041] In some embodiments, the door lock device 100 further includes a first driving assembly 30 , which is configured to drive the locking pin 23 to move to the driving slot 213 or to disengage from the driving slot 213 .

[0042] The first drive assembly 30 includes a first drive member 31, a first transmission member 32, and a lock body slider 33. The first transmission member 32 is rotatably connected between the first drive member 31 and the lock body slider 33.

[0045] The lock slider 33 has multiple limiting ridges 331 on its side facing away from the second rocker arm 22. These ridges 331 are slidably connected to the vehicle door or external housing. These ridges 331 limit the rotation of the lock slider 33, leaving the lock slider 33 free to move only along the longitudinal axis of the waist-shaped hole 221. The lock slider 33 has a guide slot 332 extending through it. The second penetration portion 232 of the locking pin 23 can be inserted into the guide slot 332, allowing the lock slider 33 to drive the locking pin 23. Alternatively, a guide slot 332 may be provided on the side of the lock slider 33 facing the first rocker arm 21, but not extending through it, to achieve the same effect.

[0046] The first worm 312 of the first driving member 31 engages with the first rack portion 321 of the first transmission member 32. The positioning post of the first transmission member 32 extends through the positioning slot of the lock body slider 33. The first transmission member 32 rotates to connect with the lock body slider 33. The second penetration portion 232 of the locking pin 23 extends through the slide slot 332 of the lock body slider 33. When the first motor 311 is started, the first worm 312 rotates, which drives the first rack portion 321 of the first transmission member 32 to rotate. The first transmission member 32 drives the lock body slider 33 to move, and the lock body slider 33 drives the locking pin 23 to move.

[0048] In some embodiments, the door lock device 100 further includes a second drive assembly 50, which is configured to drive the locking link 24 to switch between an unlocked position and a locked position. The second drive assembly 50 further includes a second drive member 51 and a second transmission member 52. The second drive member 51 and the second transmission member 52 are rotationally connected, and the second transmission member 52 and the locking link 24 are fixedly connected. The second transmission member 52 and the locking link 24 are integrally designed. The output end of the second drive member 51 is rotationally connected to the input end of the second transmission member 52. The second drive member 51 drives the second transmission member 52 and the locking link 24 to rotate together, causing the locking link 24 to switch between the unlocked position and the locked position.

[0049] Among them, the second driving member 51 includes a second motor 511 and a second worm 512, the second worm 512 is passed through the rotating shaft of the second motor 511, the second transmission member 52 includes a second rack portion 521, the second rack portion 521 is geared to the second worm 512, the second rack portion 521 is arranged on at least part of the outer peripheral wall of the second transmission member 52, the second rack portion 521 includes a plurality of circumferentially arranged helical teeth, and the plurality of helical teeth are geared to the second worm 512.

[0050] The second motor 511 of the second driving member 51 drives the second worm 512 to rotate, which in turn drives the second transmission member 52 and the locking link 24 to rotate together. When the second driving member 51 drives the locking link 24 and the second transmission member 52 to rotate clockwise, the locking link 24 is in the locked position, and the door locking device 100 is in the locked state. When the second driving member 51 drives the locking link 24 and the second transmission member 52 to rotate counterclockwise, the locking link 24 is in the unlocked position, and the door locking device 100 is in the unlocked state.

[0051] In other embodiments, the second transmission member 52 may be omitted, that is, the second driving member 51 directly drives the locking link 24 to rotate.

[0052] The door lock device 100 provided in this application can be used as a super lock and central locking system for a vehicle's front door and / or rear door. Specifically, after leaving the vehicle, the user presses the lock button in the vehicle key for the first time. The lock button can drive the second motor 511 of the second drive member 51 to rotate, and the second motor 511 drives the second worm 512 to rotate. The second worm 512 drives the second transmission member 52 and the locking link 24 to rotate clockwise. The locking link 24 is in the locked position, the door lock device 100 is in the locked state, and the central locking system is activated. The user presses the lock button in the vehicle key again. The lock button drives the first motor 311 of the first drive member 31 to rotate, and the first motor 311 drives the first worm 312 to rotate. When the first worm 312 drives the first transmission member 32 to move clockwise, the first transmission member 32 drives the lock body slider 33 to move upward, and the lock body slider 33 drives the locking pin 23 to move upward. The locking pin 23 disengages from the drive slot 213, and the super lock is activated. When the super lock is activated, the door cannot be opened if the user actuates the inner opening handle or the outer opening handle.

[0053] The user presses the unlock button on the vehicle key, which drives the first motor 311 of the first drive member 31 to rotate. The first motor 311 drives the first worm gear 312 to rotate. When the first worm gear 312 drives the first transmission member 32 counterclockwise, the first transmission member 32 drives the lock body slider 33 downward. The lock body slider 33 drives the locking pin 23 downward. The locking pin 23 is inserted into the drive slot 213, and the super lock is closed. When the super lock is closed, the user drives the inner opening handle for the first time, which drives the inner opening rocker 15 to rotate counterclockwise. The inner opening rocker 15 drives the first rocker arm 21 to rotate clockwise. The first rocker arm 21 drives the second rocker arm 22 to rotate clockwise via the locking pin 23. The second rocker arm 22 drives the locking link 24 to rotate counterclockwise, and the locking link 24 switches to the unlocked position. Then, the user actuates the inner opening handle a second time, which drives the inner opening rocker 15 to rotate counterclockwise. The inner opening rocker 15 abuts the first rocker arm 21, and the first rocker arm 21 abuts the mating rocker arm 14, thereby opening the vehicle door. Simultaneously, the unlock button drives the second motor 511 of the second driving member 51 to rotate, which in turn drives the second worm gear 512 to rotate. The second worm gear 512 drives the second transmission member 52 and the locking link 24 to rotate counterclockwise. The locking link 24 is in the unlocked position, the door lock device 100 is in the unlocked state, and the central locking is closed. The vehicle door can be opened by actuating either the inner opening handle or the outer opening handle.

[0054] In one possible scenario, after the user activates the central locking and super lock, the vehicle loses power. The vehicle key is unable to drive the first motor 311 and the second motor 511, preventing the vehicle door from opening. To address this issue, the vehicle door must be opened with a mechanical key. The door lock device 100 also includes an unlocking link 55, a rotating structure 53, and a transmission arm 54. The rotating structure 53 is connected to the mechanical key, which drives the rotating structure 53 to rotate. The rotating structure 53 rotates and connects to the transmission arm 54. The transmission arm 54 rotates and connects to the locking link 24. The locking link 24 abuts the unlocking link 55, which then rotates and connects to the lock body slider 33.

[0055] Specifically, the rotating structure 53 includes a rotating arm 531 and a lock core 532. The rotating arm 531 is fixedly mounted on the lock core 532. The outer wall of the lock core 532 is provided with a baffle, which abuts the transmission arm 54 and drives the transmission arm 54 to rotate. The transmission arm 54 includes a driving end 541, and the locking link 24 includes a driven end 243. The driving end 541 has a groove structure, and the driven end 243 can be a columnar structure. The driven end 243 is accommodated in the driving end 541. When the transmission arm 54 rotates, the driving end 541 drives the driven end 243 to rotate, thereby realizing the rotation of the locking link 24. The locking link 24 abuts the unlocking link 55. The locking link 24 and the unlocking link 55 can be arranged in a close proximity or at a distance. The unlocking link 55 is rotatably connected to the lock body slider 33. The unlocking link 55 is provided with a receiving groove, and the lock body slider 33 is provided with a positioning protrusion, which is inserted into the receiving groove so that the unlocking link 55 is rotatably connected to the lock body slider 33. In other examples, the lock body slider 33 is provided with a positioning protrusion, and the unlocking link 55 is provided with a receiving groove, and the positioning protrusion is inserted into the receiving groove so that the unlocking link 55 is rotatably connected to the lock body slider 33.

[0056] The user rotates the mechanical key. When the key abuts the rotating arm 531, the rotating arm 531 and the lock cylinder 532 rotate counterclockwise. The retaining plate of the lock cylinder 532 abuts the transmission arm 54, rotating it clockwise. The driving end 541 of the transmission arm 54 drives the locking link 24 counterclockwise, positioning the locking link 24 in the unlocked position and closing the central locking system. Because the locking link 24 abuts the unlocking link 55, the unlocking link 55 rotates clockwise. The unlocking link 55 drives the lock body slider 33 downward through the receiving groove and the positioning protrusion. The lock body slider 33 drives the locking pin 23 through the driving groove 213, closing the super lock. The user can open the vehicle door by actuating the exterior or interior opening handle.

[0057] In some embodiments, referring to FIG. 4 , the door lock device 100 further includes a housing, which includes a first housing 61 and a second housing 62 that can be mated and connected to each other.

The second transmission member 52 and the locking link 24 rotate together around the fifth connecting shaft 615. The inner wall of the first housing 61 is provided with a sixth connecting shaft 616, which is passed through the transmission arm 54. The transmission arm 54 rotates around the sixth connecting shaft 616. The inner wall of the first housing 61 is also provided with a mounting hole 617, through which the rotating structure 53 can be fixedly passed. The rotating arm 531 extends out of the mounting hole 617, which facilitates the insertion of the rotating arm 531 into the lock cylinder 532. The first housing 61 is also provided with a first fixing groove 618, in which the first driving member 31 is received and fixed. The first housing 61 is also provided with a second fixing groove 619, in which the second driving member 51 is received and fixed.

[0058] The following describes the complete operation of the door lock device 100 in detail. It should be understood that the vehicle key includes an unlock button and a lock button. Pressing the lock button once activates the central locking system, while pressing the lock button a second time activates the super lock. Pressing the unlock button deactivates both the super lock and the central locking system.

[0059] The process for closing the central locking system is as follows. Pressing the unlock button on the vehicle key activates the second motor 511, which in turn drives the second worm gear 512. The second worm gear 512 drives the second transmission member 52 and the locking link 24 counterclockwise, which in turn drives the linkage 11 to the right. This unlocks the locking link 24, unlocking the door lock device 100 and closing the central locking system.

[0060] When the central locking system is closed, the door opening process is as follows: the inner opening handle drives the inner opening rocker 15 to rotate counterclockwise, the inner opening rocker 15 abuts the first rocker arm 21, and the inner opening rocker 15 drives the first rocker arm 21 to rotate clockwise, and the second rocker arm 22 abuts the matching rocker arm 14 to open the door.

[0061] The central locking system activates as follows: Pressing the lock button on the vehicle key activates the second motor 511, which in turn drives the second worm gear 512. The second worm gear 512 drives the second transmission member 52 and the locking link 24 clockwise, locking the link 24 to the locked position. The door locking device 100 is locked, and the central locking system is activated.

[0062] When the central locking system is activated, the door opening process proceeds as follows. There are two ways to open the door. First, the interior opening handle is actuated. This first rotates the interior opening rocker 15 counterclockwise, which in turn rotates the first rocker arm 21 clockwise. The first rocker arm 21, via the locking pin 23, rotates the second rocker arm 22 clockwise. The second rocker arm 22 then rotates the locking link 24 counterclockwise, placing the locking link 24 in the unlocked position and unlocking the door lock device 100. Then, the interior opening handle is actuated a second time, rotating the interior opening rocker 15 counterclockwise. The interior opening rocker 15 abuts the first rocker arm 21, which then rotates the first rocker arm 21 counterclockwise. The first rocker arm 21 abuts the mating rocker arm 14, opening the door. In other words, the door can be opened by pulling the interior opening handle twice. Secondly, the unlock button of the vehicle key is pressed to drive the second driving member 51 to reverse, so that the door lock device 100 is in the unlocked state, and the inner opening handle or the outer opening handle can be driven to directly open the vehicle door.

[0063] The process of closing the super lock is as follows: Pressing the unlock button on the vehicle key activates the first motor 311, which drives the first worm 312 to rotate. The first worm 312 drives the first transmission member 32 to move counterclockwise. The first transmission member 32 drives the lock body slider 33 to slide downward. The lock body slider 33 drives the locking pin 23 to slide downward. The locking pin 23 is inserted into the driving slot 213, and the super lock is closed.

[0064] When the super lock is closed, the movement process for opening the door is as follows: The door can be opened by pulling the inner opening handle twice.

[0065] The movement process of activating the super lock is as follows. Press the lock button of the vehicle key for the second time, and the lock button starts the first motor 311, and the first motor 311 drives the first worm 312 to rotate. When the first worm 312 drives the first transmission member 32 to move clockwise, the first transmission member 32 drives the lock body slider 33 to slide upward, and the lock body slider 33 drives the locking pin 23 to slide upward, and the locking pin 23 disengages from the drive slot 213, and the central lock is activated. The locking pin 23 disengages from the drive slot 213, and the movements of the first rocker arm 21 and the second rocker arm 22 are relatively independent. The second rocker arm 22 and the locking link 24 are not driven by external force, and the locking link 24 is still in the locked position. In this way, the door lock device 100 is in a locked state, and the door cannot be opened by driving the inner or outer handle.

[0066] When the central locking and super lock are enabled, the mechanical key's movement to open the vehicle door is as follows. When the mechanical key abuts the rotating arm 531, the rotating arm 531 and the lock cylinder 532 rotate counterclockwise together. The baffle of the lock cylinder 532 abuts the transmission arm 54, rotating clockwise. The drive end 541 of the transmission arm 54 drives the locking link 24 to rotate counterclockwise, placing the locking link 24 in the unlocked position and closing the central locking. Because the locking link 24 abuts the unlocking link 55, the unlocking link 55 rotates clockwise. The unlocking link 55 drives the lock body slider 33 downward via the receiving slot and positioning protrusion. The lock body slider 33 drives the locking pin 23 through the drive slot 213, closing the super lock. The user can open the vehicle door by actuating the exterior or interior opening handle.
