The central locking mechanism and the super locking mechanism operate independently, that is, the locking operation of any one of the locking mechanisms can disconnect the transmission chain, so that the door lock cannot be opened from inside or outside. The central locking mechanism is externally connected and can be unlocked by an in-vehicle locking button or a knob, while the super locking mechanism cannot be externally connected and can only be unlocked by an electric unlocking and / or a mechanical key unlocking. Therefore, when the central locking mechanism and the super locking mechanism are both in the locked state, even if the in-vehicle locking button is operated after the window is broken, only the externally connected central locking mechanism can be unlocked, and the super locking mechanism cannot be unlocked, so the door cannot be opened, greatly improving the safety of the vehicle.

[0004] However, in the application scenarios of drive motor failure of the super locking mechanism and vehicle power loss, the door lock cannot be opened from inside due to the unlocking of the super locking mechanism, and there is a risk that a legal operator cannot open the door and is mistakenly locked in the vehicle.

DETAILED DESCRIPTION

[0052] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0053] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application or its application or uses.

[0054] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, techniques, methods, and devices should be considered part of the description of the present application.

[0055] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0056] It should be noted that like numbers and letters refer to like items throughout the drawings, and that, once an item is defined in one drawing, it should not require further discussion in subsequent drawings.

[0057] As shown in FIG. 1 and FIG. 2, in some embodiments of the present application, the door lock structure 100 includes a first locking member 1 and a second locking member 2, the second locking member 2 can drive the first locking member 1 to move under the action of external driving force, so that the first locking member 1 is in an unarming state.

[0058] Wherein, the first locking member 1 is in an armed state, and the door lock structure 100 is in an inner locking state. The inner locking state means that the door lock cannot achieve double-pull inner handle unlocking, and the inner and outer mechanical locks cannot be opened.

[0059] The second locking member 2 is in an armed state, and the door lock structure 100 is in an inner unlocking state. The inner unlocking state means that the inner and outer mechanical locks cannot be opened, but the inner handle can be opened by double pulling, wherein the first pulling of the inner handle can disarm the second locking member 2, and the second pulling of the inner handle achieves unlocking of the door lock.

[0060] Wherein, the first locking member 1 belongs to a super lock mechanism, the super lock mechanism has a super lock armed state and a super lock disarmed state, in the super lock armed state, the door lock structure 100 cannot be unlocked; in the super lock disarmed state, the door lock structure 100 can be unlocked.

[0061] The second locking member 2 belongs to a central locking mechanism, the central locking mechanism has a central lock armed state and a central lock disarmed state, in the central lock armed state, the door lock structure 100 cannot be unlocked; in the central lock disarmed state, the door lock structure 100 can be unlocked.

[0062] Since the second locking member 2 can drive the first locking member 1 to move to the disarmed state, when disarming the second locking member 2, the second locking member 2 can drive the first locking member 1 to move to the disarmed state, so that the door lock structure 100 can be unlocked by the inner handle to open the door, avoiding the risk that the legal operator cannot open the door in the application scenario of drive motor failure of the super lock mechanism and vehicle power loss, and the risk of being mistakenly locked in the vehicle, so that the entire door lock structure 100 can ensure the risk in the vehicle while improving the use safety.

[0063] In the door lock structure 100 in the embodiments of the present application, the second locking member 2 can drive the first locking member 1 to move to the disarmed state, so that when disarming the second locking member 2, the second locking member 2 can drive the first locking member 1 to move to the disarmed state, so that the door lock structure 100 can be unlocked to open the door, avoiding the risk that the legal operator cannot open the door in the application scenario of drive motor failure of the super lock mechanism and vehicle power loss, and the risk of being mistakenly locked in the vehicle, so that the entire door lock structure 100 can ensure the risk in the vehicle while improving the use safety.

[0064] In some embodiments of the present application, as shown in FIG. 2 and FIG. 3, the door lock structure 100 comprises a linkage rod 3 connected with the second locking member 2 and the first locking member 1 respectively, the second locking member 2 can drive the linkage rod 3, and then drive the first locking member 1 to move to the unblocking direction.

[0065] In some embodiments of the present application, when the second locking member 2 moves to the first direction, the second locking member 2 drives the linkage rod 3 to move, so as to drive the first locking member 1 to move to the unblocking state, and when the second locking member 2 moves to the second direction, the second locking member 2 is disconnected with the linkage rod 3.

[0066] The first locking member 1 and the second locking member 2 are connected by the linkage rod 3 in one-way coupling, the second locking member 2 can only drive the first locking member 1 to move to the unblocking state through the linkage rod 3 when moving to the unblocking direction, therefore, the locking operation of the second locking member 2 does not affect the unblocking state of the first locking member 1.

[0067] In some embodiments of the present application, the first locking member 1 is a cam structure, the first locking member 1 is provided with a fixed clamping table 11 protruding to the direction of the linkage rod 3, the fixed clamping table 11 is arranged away from the rotation center of the first locking member 1, and the fixed clamping table 11 is connected with the linkage rod 3, so as to drive the first locking member 1 to rotate around the rotation center under the driving of the linkage rod 3.

[0068] In some embodiments of the present application, the fixed clamping table 11 is arranged on the axial end surface of the first locking member 1, the linkage rod 3 is provided with a clamping table mounting hole 32, and the linkage rod 3 is sleeved on the fixed clamping table 11 through the clamping table mounting hole 32.

[0069] In some embodiments of the present application, the end of the fixed clamping table 11 away from the first locking member 1 is provided with a pin hole penetrating through in the radial direction, after the linkage rod 3 is sleeved on the fixed clamping table 11 through the clamping table mounting hole 32, the end provided with the pin hole penetrates out of the clamping table mounting hole 32, and a pin is inserted into the pin hole.

[0070] In some embodiments of the present application, the end of the fixed clamping table 11 close to the first locking member 1 is provided with a limiting boss 12 protruding from the outer peripheral surface of the fixed clamping table 11, the limiting boss 12 is used for limiting the linkage rod 3, so as to limit the distance between the linkage rod 3 and the axial end surface of the first locking member 1, and avoid the interference between the linkage rod 3 and the first locking member 1 when the distance between the linkage rod 3 and the first locking member 1 is too small.

[0071] In some embodiments of the present application, the second locking member 2 is provided with a first protruding structure 21, and the linkage rod 3 is connected with the first protruding structure 21, so as to drive the linkage rod 3 to move when the second locking member 2 moves.

[0072] In some embodiments of the present application, the linkage rod 3 is provided with a coupling hole 31; the first protruding structure 21 is provided with a stop portion, at least part of the first protruding structure 21 extends into the coupling hole 31, so that when the second locking member 2 moves, the stop portion connects with the inner wall of the coupling hole 31 to drive the linkage rod 3 to move.

[0073] When the second locking member 2 moves in the first direction, the stop portion is circumferentially stopped by the inner wall of the coupling hole 31, so that when the second locking member 2 moves, the linkage rod 3 is driven to move, and then the linkage rod 3 drives the first locking member 1 to rotate in the unlocking direction.

[0074] In some embodiments of the present application, as shown in FIG. 2, the stop portion has a guide surface which gradually protrudes towards the linkage rod 3 from the direction of the end of the linkage rod 3 connected with the first locking member 1 to the end of the linkage rod 3 connected with the second locking member 2.

[0075] As shown in FIG. 9, when the second locking member 2 moves in the first direction, the linkage rod 3 is circumferentially stopped by the second locking member 2, so that the linkage rod 3 drives the first locking member 1 to rotate in the unlocking direction.

[0076] As shown in FIG. 10, when the second locking member 2 moves in the second direction, the first protruding structure 21 is separated from the coupling hole 31, so as to realize the one-way coupling of the linkage rod 3 and the second locking member 2, thereby realizing the one-way coupling connection of the first locking member 1 and the second locking member 2.

[0077] 2' in FIG. 9 is the second locking member moving to the unlocking state, 21 in FIG. 12 refers to the first protruding structure of the second locking member 2 moving to the unlocking state, and 21' refers to the first protruding structure of the second locking member 2 moving to the locking state.

[0078] In some embodiments of the present application, the first protruding structure 21 is plate-shaped, the coupling hole 31 is a long hole extending along the plane where the first protruding structure 21 is located, and the first protruding structure 21 can rotate circumferentially in the coupling hole 31 until it connects with the inner wall of the coupling hole 31.

[0079] The movement track of the plate-shaped first protruding structure 21 is relatively regular, which is conducive to controlling the positional relationship between the first protruding structure 21 and the coupling hole 31, so as to facilitate the turning of the first protruding structure 21 into the coupling hole 31.

[0080] In some embodiments of the present application, the height of the coupling hole 31 is slightly greater than the thickness of the first protruding structure 21.

[0081] In some embodiments of the present application, as shown in FIG. 4, the door lock structure 100 further comprises an opening mechanism, and the central locking mechanism is connected with the opening mechanism in the unlocking state, at this time, the inner opening operation and the outer opening operation can unlock the door lock structure 100.

[0082] As shown in FIG. 4 and FIG. 5, the opening mechanism includes an opening arm linkage block 9, and the door lock structure 100 further includes a locking arm 103 in transmission connection with the second locking member 2. When the second locking member 2 moves in the direction of releasing the central control lock, the locking arm 103 moving with the second locking member 2 is in the overlapping state with the opening arm linkage block 9, and the position of overlapping is indicated by B in FIG. 6. At this time, the door lock structure 100 can be opened by operating the inner opening arm 6 and the outer opening arm 104. The direction of releasing the central control lock in FIG. 4 refers to the direction of the second locking member 2 from the central control lock-on state to the central control lock release state.

[0083] As shown in FIG. 7 and FIG. 8, when the second locking member 2 moves to the central control lock-on state, the locking arm 103 rotating with the second locking member 2 rotates in the direction away from the opening arm linkage block 9, and the opening arm linkage block 9 is in the disengaged state with the locking arm 103. The separation distance between the opening arm linkage block 9 and the locking arm 103 is indicated by C in FIG. 8. At this time, the opening mechanism is in the disengaged state with the central control lock mechanism, and the door lock structure 100 cannot be unlocked to open the door by operating the opening mechanism.

[0084] The direction of releasing the central control lock in FIG. 4 refers to the direction of the second locking member 2 from the central control lock release state to the central control lock-on state.

[0085] In some embodiments of the present application, as shown in FIG. 2 and FIG. 10, the door lock structure 100 further includes a lock cylinder transmission arm 8 connected with the second locking member 2. When mechanically unlocking, the second locking member 2 is driven to rotate by the lock cylinder transmission arm 8 to achieve the unlocking or locking of the second locking member 2.

[0086] The door lock structure 100 includes a lock tongue and a lock cylinder knob 7 mounted on the door. The lock tongue can be separated from the vehicle body when the lock cylinder knob 7 rotates to achieve the unlocking of the door lock structure 100, and can be inserted into the vehicle body to achieve the locking of the door lock structure 100.

[0087] The lock cylinder knob 7 is in transmission connection with the second locking member 2 through the lock cylinder transmission arm 8. When the mechanical key is inserted into the lock hole of the lock cylinder knob 7 and rotated, the lock cylinder knob 7 drives the second locking member 2 to rotate, so that the second locking member 2 rotates to the central control lock release state. The second locking member 2 can drive the first locking member 1 to move to the super lock release state to achieve the unlocking of the door, thereby realizing the mechanical key unlocking function, and avoiding the situation that the mechanical key only releases the central control lock mechanism and can open the door outside, while the super lock mechanism is still in the super lock locking state and cannot open the door inside.

[0088] In some embodiments of the present application, the lock cylinder transmission arm 8 is provided with a transmission boss 81 protruding towards the second locking member 2, and the second locking member 2 is provided with a lock cylinder connecting groove. The transmission boss 81 is inserted into the lock cylinder connecting groove, so that the lock cylinder transmission arm 8 can drive the second locking member 2 to unlock under the driving of external force.

[0090] In some embodiments of the present application, as shown in FIG. 3, the second locking member 2 and the first locking member 1 are arranged in the height direction of the vehicle, and the linkage rod 3 is arranged in the height direction of the vehicle, so as to reduce the size of the door lock structure 100 in the length direction of the vehicle. Compared with the space in the length direction of the vehicle, the space in the height direction of the vehicle is larger, and the transmission chain of the central locking mechanism and the super locking mechanism is arranged in the height space of the vehicle, which is beneficial to reduce the modeling limitation requirement of the door lock structure 100 to the door and the vehicle body, and is beneficial to the diversification design of the vehicle.

[0091] In some embodiments of the present application, as shown in FIG. 2, the door lock structure 100 further comprises an inside opening linkage plate 4 and an inside opening clutch member 5, the first locking member 1 is rotationally connected with the inside opening linkage plate 4, and the inside opening linkage plate 4 is in transmission connection with the second locking member 2. The inside opening clutch member 5 is rotationally connected with the inside opening linkage plate 4.

[0092] The inside opening clutch member 5 cooperates with the first locking member 1, and the inside opening clutch member 5 can drive the first locking member 1 to be in the upper insurance state or the un-insurance state under the drive of the first locking member 1. When the first locking member 1 is in the upper insurance state, the door lock is in the inside locking state and cannot be unlocked from inside the vehicle, and when the first locking member 1 is in the un-insurance state, the door lock can be unlocked from inside the vehicle.

[0093] When the first locking member 1 is in the un-insurance state, the inside opening clutch member 5 can drive the inside opening linkage plate 4 to move the second locking member 2 in the unlocking direction under the drive of external force.

[0094] As shown in FIG. 10, when the door lock is in the full upper insurance state and needs to be opened from inside, that is, the first locking member 1 and the second locking member 2 are both in the upper insurance state, an external driving force (such as a motor) is used to drive the second locking member 2 to move in the un-insurance direction, the second locking member 2 drives the first locking member 1 to move in the un-insurance direction, the first locking member 1 drives the clutch boss 52 to move, so that the first locking member 1 is in the un-insurance state, so that the door lock structure 100 can be unlocked from inside, and then an external force is used to drive the inside opening clutch member 5 to drive the inside opening linkage plate 4, so that the inside opening linkage plate 4 drives the second locking member 2 to move in the unlocking direction to unlock the door lock and open the door.

[0095] In some embodiments of the present application, as shown in FIG. 2, the inside opening clutch member 5 comprises a block body 51 and a clutch boss 52 connected with the block body 51, and the block body 51 is rotationally connected with the inside opening linkage plate 4.

[0096] The first locking member 1 is provided with a sliding surface 13 extending in the radial direction thereof and a supporting surface 14 extending in the circumferential direction thereof, and the radially outer side of the sliding surface 13 is connected to the circumferentially one side of the supporting surface 14; the inner opening linkage plate 4 is provided with a second protruding structure 44.

[0097] The first locking member 1 drives the clutch boss 52 to move relative to the inner opening linkage plate 4, when the clutch boss 52 is matched with the sliding surface 13, the first locking member 1 is in the super lock disarming state, the clutch boss 52 is connected with the second protruding structure 44 in the circumferential direction of the first locking member 1, and the clutch boss 52 can drive the inner opening linkage plate 4 to rotate under the driving of external force.

[0098] When the clutch boss 52 is matched with the supporting surface 14, the first locking member 1 is in the super lock arming state, and the clutch boss 52 is disconnected with the second protruding structure 44.

[0099] It should be noted that the central locking mechanism drives the second locking member 2 to rotate through the central control motor 101, and the super lock mechanism drives the first locking member 1 to rotate through the super lock motor 102.

[0100] As shown in FIG. 10, the first locking member 1 is in the arming state, the second locking member 2 is in the arming state, that is, the door lock structure 100 is in the double arming state, the central locking mechanism controls the second locking member 2 to rotate in the disarming direction, the second locking member 2 drives the first locking member 1 to rotate in the disarming direction, the clutch boss 52 slides from the supporting surface 14 to the sliding surface 13 to be clamped between the second protruding structure 44 and the sliding surface 13, thereby linking the inner opening linkage plate 4 and the first locking member 1 together. At this time, the first locking member 1 and the second locking member 2 are both in the disarming state, and the door lock structure 100 can be unlocked.

[0101] The super lock disarming direction in FIG. 10 refers to the direction in which the first locking member 1 rotates from the super lock arming state to the super lock disarming state. The super lock arming direction refers to the direction in which the first locking member 1 rotates from the super lock disarming state to the super lock arming state.

[0102] As shown in FIG. 11, the first locking member 1 is in the super lock disarming state, the second locking member 2 is in the central control disarming state, that is, the door lock structure 100 is in the double disarming state, the super lock motor 102 drives the first locking member 1 to rotate to the super lock arming state, as shown in FIG. 10, the sliding surface 13 pushes the clutch boss 52 to slide to the supporting surface 14, so that the clutch boss 52 and the first locking member 1 are disconnected, the inner opening clutch 5 cannot drive the inner opening linkage plate 4 under the driving of external force, thereby the second locking member 2 cannot move in the unlocking direction, so that the door lock structure 100 can only be unlocked to open the door when the first locking member 1 and the second locking member 2 are both in the disarming state.

[0103] The inner opening clutch 5 is preferably made of a plastic material with good wear resistance and strength.
