[0002] The vehicle door lock of the related art is provided with a double locking and unlocking mechanism, which includes a central locking mechanism and a super locking mechanism. The central locking mechanism and the super locking mechanism operate independently, that is, the locking operation of any set of locking mechanisms can disconnect the transmission chain, so that the door lock cannot be opened from the inside or outside. The central locking mechanism is connected to the outside and can be unlocked by a locking button or dial inside the vehicle, while the super locking mechanism cannot be connected to the outside and can only be unlocked by electric unlocking and / or a mechanical key. Therefore, when both the central locking mechanism and the super locking mechanism are in a locked state, even if the locking button inside the vehicle is operated to unlock after breaking the window, only the central locking mechanism connected to the outside can be unlocked, and the super locking mechanism cannot be unlocked, so the door cannot be opened, which greatly improves the safety of the vehicle.

DETAILED DESCRIPTION

[0045] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a door lock structure, including 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 an external driving force to put the first locking member 1 in an unlocked state.

[0047] The first locking member 1 is in the upper safety state, and the door lock structure 100 is in the inner locking state. The inner locking state means that the door lock cannot be unlocked by double-pulling the inner handle, and both the inner and outer mechanical locks cannot be opened.

[0048] When the second locking member 2 is in the secured state, the door lock structure 100 is in the inner unlocked state. The inner unlocked state means that both 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 release the second locking member 2, and the second pulling of the inner handle can unlock the door lock.

[0049] Among them, the first locking member 1 belongs to a super lock mechanism, and the super lock mechanism has a super lock safety state and a super lock safety release state. In the super lock safety state, the door lock structure 100 cannot be unlocked; in the super lock safety release state, the door lock structure 100 can be unlocked.

[0050] The second locking member 2 belongs to the central locking mechanism, which has a central safety state and a central safety release state. In the central safety state, the door lock structure 100 cannot be unlocked; in the central safety release state, the door lock structure 100 can be unlocked.

[0051] Since the second locking member 2 can drive the first locking member 1 to move to the disarmed state, when the second locking member 2 is disarmed, 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 of failure of the driving motor of the super lock mechanism, the inability of the legitimate operator to open the door, and the risk of being accidentally locked in the vehicle in the application scenario of the whole vehicle being low on power, so that the entire door lock structure 100 improves the safety of use while protecting the risks in the vehicle.

[0052] In the door lock structure 100 of the present invention, the second locking member 2 can drive the first locking member 1 to move to the disarmed state. Therefore, when the second locking member 2 is disarmed, 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 of failure of the driving motor of the super lock mechanism and the risk of the legitimate operator being unable to open the door and being mistakenly locked in the car in the application scenario of the whole vehicle being low on power, so that the entire door lock structure 100 improves the safety of use while protecting the risks in the vehicle.

[0053] In one embodiment, if Figure 2 and Figure 3 As shown, the door lock structure 100 includes a linkage rod 3, which is respectively connected to the second locking member 2 and the first locking member 1. The second locking member 2 can drive the linkage rod 3, thereby driving the first locking member 1 to move in the release direction.

[0054] In one embodiment, when the second locking member 2 moves in 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 released state. When the second locking member 2 moves in the second direction, the second locking member 2 is disconnected from the linkage rod 3.

[0055] The first locking member 1 and the second locking member 2 are connected by a one-way coupling via a linkage rod 3. The second locking member 2 can only drive the first locking member 1 to move to the unlatched state via the linkage rod 3 when moving in the unlatched direction. Therefore, the locking operation of the second locking member 2 does not affect the unlatched state of the first locking member 1.

[0056] In one embodiment, the first locking member 1 is a cam structure, and a fixed clamping platform 11 protruding toward the linkage rod 3 is provided on the first locking member 1. The fixed clamping platform 11 is set offset from the rotation center of the first locking member 1, and the fixed clamping platform 11 is connected to the linkage rod 3 to push the first locking member 1 to rotate around the rotation center under the drive of the linkage rod 3.

[0057] In one embodiment, the fixed clamping platform 11 is arranged on the axial end surface of the first locking member 1 , and a clamping platform mounting hole 32 is arranged on the linkage rod 3 . The linkage rod 3 is sleeved on the fixed clamping platform 11 through the clamping platform mounting hole 32 .

[0058] In one embodiment, a pin hole extending radially through the fixed clamp 11 is provided at one end away from the first locking member 1. After the linkage rod 3 is sleeved on the fixed clamp 11 through the clamp mounting hole 32, the end provided with the pin hole passes through the clamp mounting hole 32, and a pin is inserted into the pin hole.

[0059] In one embodiment, a limiting boss 12 is provided at one end of the fixed clamping platform 11 close to the first locking member 1. The limiting boss 12 protrudes from the outer peripheral surface of the fixed clamping platform 11 and is used to limit the linkage rod 3 to limit the distance between the linkage rod 3 and the axial end face of the first locking member 1, so as to avoid the interference of the moving linkage rod 3 with the first locking member 1 when the distance between the linkage rod 3 and the first locking member 1 is too small.

[0060] In one embodiment, a first protruding structure 21 is provided on the second locking member 2 , and the linkage rod 3 is connected to the first protruding structure 21 to drive the linkage rod 3 to move when the second locking member 2 moves.

[0061] In one embodiment, a coupling hole 31 is provided on the linkage rod 3; the first protruding structure 21 is provided with a stopping portion, and at least a portion of the first protruding structure 21 extends into the coupling hole 31, so that when the second locking member 2 moves, the stopping portion is connected to the inner wall of the coupling hole 31 to drive the linkage rod 3 to move.

[0062] When the second locking member 2 moves in the first direction, the blocking portion and the inner wall of the coupling hole 31 are circumferentially blocked to drive the linkage rod 3 to move when the second locking member 2 moves, and then the linkage rod 3 drives the first locking member 1 to rotate in the release direction.

[0063] In one embodiment, if Figure 2 As shown, the stopper has a guide surface, which gradually protrudes toward the linkage rod 3 from one end of the linkage rod 3 connected to the first locking member 1 to one end of the linkage rod 3 connected to the second locking member 2 .

[0064] like Fig. 9 As shown, when the second locking member 2 moves in the first direction, the linkage rod 3 and the second locking member 2 are circumferentially blocked, so that the linkage rod 3 drives the first locking member 1 to rotate in the release direction.

[0065] like Fig.10 As shown, when the second locking member 2 moves in the second direction, the first protruding structure 21 disengages from the coupling hole 31 to achieve unidirectional coupling between the linkage rod 3 and the second locking member 2, thereby achieving a unidirectional coupling connection between the first locking member 1 and the second locking member 2.

[0066] Fig. 9 2' in the figure is the second locking member moved to the unlocked state, Fig.12 The reference numeral 21 refers to the first protruding structure 21 of the second locking member 2 moved to the released state, and the reference numeral 21 ′ refers to the first protruding structure 21 of the second locking member 2 moved to the secured state.

[0067] In one embodiment, the first protruding structure 21 is plate-shaped, and the coupling hole 31 is an elongated hole extending along the plane where the first protruding structure 21 is located. The first protruding structure 21 can rotate circumferentially in the coupling hole 31 until it is connected to the inner wall of the coupling hole 31 .

[0068] The movement trajectory 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 that the first protruding structure 21 can turn into the coupling hole 31 .

[0069] In one embodiment, the height of the coupling hole 31 is slightly greater than the thickness of the first protruding structure 21 .

[0070] In one embodiment, if Figure 4 As shown, the door lock structure 100 also includes an opening mechanism, and the central locking mechanism is connected to the opening mechanism in the released state. At this time, the internal opening operation and the external opening operation can unlock the door lock structure 100.

[0071] Specifically, Figure 4 and Figure 5 As shown, the opening mechanism includes an opening arm linkage block 9, and the door lock structure 100 also includes a locking arm 103, which is transmission-connected with the second locking member 2. When the second locking member 2 moves in the release direction, the locking arm 103 moving with the second locking member 2 is in an overlapping state with the opening arm linkage block 9. Figure 6 B in the figure indicates the overlapping position. At this time, the door lock structure 100 can be opened by operating the inner opening arm 6 and the outer opening arm 104. Figure 4 The central control release direction refers to the direction in which the second locking member 2 moves from the central control safety state to the central control release state.

[0072] like Figure 7 and Figure 8As shown, when the second locking member 2 moves to the central control safety state, the locking arm 103 rotating with the second locking member 2 rotates in a direction away from the opening arm linkage block 9, and the opening arm linkage block 9 and the locking arm 103 are in a disengaged state. Figure 8 C in the figure indicates the separation distance between the opening arm linkage block 9 and the locking arm 103. At this time, the opening mechanism and the central locking mechanism are in a disengaged state, and the operation of the opening mechanism cannot unlock the door lock structure 100 to open the door.

[0073] Figure 4 The central control safety direction refers to the direction in which the second locking member 2 moves from the central control safety-released state to the central control safety-on state.

[0074] In one embodiment, if Figure 2 and Fig.10 As shown, the door lock structure 100 also includes a lock core transmission arm 8, which is connected to the second locking member 2 and drives the second locking member 2 to rotate during mechanical unlocking to achieve unlocking or locking of the second locking member 2.

[0075] The door lock structure 100 includes a lock tongue and a lock core knob 7 installed on the vehicle door. The lock tongue can be separated from the vehicle body to unlock the door lock structure 100 when the lock core knob 7 is rotated, and can also be inserted into the vehicle body to lock the door lock structure 100.

[0076] The lock core knob 7 is connected to the second locking member 2 through the lock core transmission arm 8, so that when the mechanical key is inserted into the lock hole of the lock core knob 7 and rotated, the lock core knob 7 drives the second locking member 2 to rotate, so that the second locking member 2 rotates to the central control unlatched state, and the second locking member 2 can drive the first locking member 1 to move to the super lock unlatched state, so as to be able to unlock and open the vehicle door, thereby realizing the mechanical key unlocking function, avoiding the situation where the mechanical key only releases the central control locking mechanism and can open the vehicle door from the outside, while the super lock mechanism is still in the super lock locked state and cannot open the vehicle door from the inside.

[0077] In one embodiment, a transmission boss 81 protruding toward the second locking member 2 is provided on the lock core transmission arm 8, and a lock core connecting groove is provided on the second locking member 2. The transmission boss 81 is inserted into the lock core connecting groove, so that the lock core transmission arm 8 can drive the second locking member 2 to unlock under the drive of external force.

[0078] In one embodiment, a rotating shaft is provided on the lock core knob 7 , and a rotating shaft mounting hole is provided on one end of the lock core transmission arm 8 . The rotating shaft is inserted into the rotating shaft mounting hole so that the lock core transmission arm 8 is rotatably connected to the lock core knob 7 .

[0079] In one embodiment, if Figure 3As shown, the second locking member 2 and the first locking member 1 are arranged at intervals along the height direction of the vehicle, and the linkage rod 3 is arranged along the height direction of the vehicle 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 along the height space of the vehicle, which is conducive to reducing the shape restriction requirements of the door lock structure 100 on the door and the body, and is conducive to the diversified design of the vehicle.

[0080] In one embodiment, if Figure 2 As shown, the door lock structure 100 further includes an inner opening linkage plate 4 and an inner opening clutch 5, the first locking member 1 is rotatably connected to the inner opening linkage plate 4, and the inner opening linkage plate 4 is transmission-connected to the second locking member 2. The inner opening clutch 5 is rotatably connected to the inner opening linkage plate 4.

[0081] The inner clutch 5 cooperates with the first locking member 1, and the inner clutch 5 can put the first locking member 1 in a safety-on state or a safety-off state under the drive of the first locking member 1. When the first locking member 1 is in the safety-on state, the door lock is in an inner locking state and cannot be unlocked in the vehicle. When the first locking member 1 is in the safety-off state, the door lock can be unlocked in the vehicle.

[0082] When the first locking member 1 is in the unlocked state, the inner opening clutch member 5 can drive the inner opening linkage plate 4 under the drive of an external force to move the second locking member 2 in the unlocking direction.

[0083] like Fig.10 As shown, when the door lock is in the fully secured state and the door needs to be opened from the inside, that is, the first locking member 1 and the second locking member 2 are both in the secured state, an external driving force (such as a motor) is used to drive the second locking member 2 to move in the unlocking direction, and the second locking member 2 drives the first locking member 1 to move in the unlocking direction, and the first locking member 1 drives the clutch boss 52 to move, so that the first locking member 1 is in the unlocking state, so that the door lock structure 100 can be opened and unlocked from the inside, and then an external force is used to drive the inner opening clutch member 5 to drive the inner opening linkage plate 4, so that the inner opening linkage plate 4 drives the second locking member 2 to move in the unlocking direction, so as to unlock the door lock and open the door.

[0084] In one embodiment, Figure 2 As shown, the inner opening clutch 5 includes a block body 51 and a clutch boss 52 connected to the block body 51 , and the block body 51 is rotatably connected to the inner opening linkage plate 4 .

[0085] 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 radial outer side of the sliding surface 13 is connected to one circumferential side of the supporting surface 14 ; the inwardly opening linkage plate 4 is provided with a second protruding structure 44 .

[0086] 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 cooperates with the sliding surface 13, the first locking member 1 is in a super lock and release safety state. The clutch boss 52 is connected to the second protruding structure 44 in the circumferential direction of the first locking member 1. The clutch boss 52 can drive the inner opening linkage plate 4 to rotate under the drive of external force.

[0087] When the clutch boss 52 cooperates with the support surface 14 , the first locking member 1 is in a super-locked safety state, and the clutch boss 52 is disconnected from the second protruding structure 44 .

[0088] It should be noted that the central locking mechanism drives the second locking member 2 to rotate via the central locking motor 101 , and the super locking mechanism drives the first locking member 1 to rotate via the super locking motor 102 .

[0089] Specifically, Fig.10 As shown, the first locking member 1 is in the insurance state, and the second locking member 2 is in the insurance state, that is, the door lock structure 100 is in a double insurance state, the central control locking mechanism controls the second locking member 2 to rotate in the insurance release direction, the second locking member 2 drives the first locking member 1 to rotate in the insurance release direction, and the clutch boss 52 slides from the support surface 14 to the sliding surface 13 to be stuck between the second protruding structure 44 and the sliding surface 13, and the inner opening linkage plate 4 and the first locking member 1 are linked together. At this time, the first locking member 1 and the second locking member 2 are both in the insurance release state, and the door lock structure 100 can be unlocked.

[0090] Fig.10 The super lock release direction in the super lock state refers to the direction in which the first locking member 1 turns from the super lock safety state to the super lock release state. The super lock safety direction refers to the direction in which the first locking member 1 turns from the super lock safety state to the super lock safety state.

[0091] like Fig.11 As shown, the first locking member 1 is in the super lock release state, and the second locking member 2 is in the central control release state, that is, the door lock structure 100 is in the double release state, and the super lock motor 102 drives the first locking member 1 to rotate to the super upper safety state, as shown in FIG. Fig.10 As shown, the sliding surface 13 pushes the clutch boss 52 to slide toward the supporting surface 14, so that the clutch boss 52 and the first locking member 1 are disconnected, and the inner opening clutch member 5 cannot drive the inner opening linkage plate 4 under the drive of external force, thereby unable to drive the second locking member 2 to move in the unlocking direction, so that the door lock structure 100 can only unlock and open the vehicle door when the first locking member 1 and the second locking member 2 are both in the released safety state.

[0092] The inner clutch 5 is preferably made of a plastic material with good wear resistance and strength.

[0093] In one embodiment, the door lock structure 100 further includes an elastic return member 106 , and the elastic return member 106 is used to provide a return force for the clutch boss 52 .

[0094] In one embodiment, the elastic return member 106 is a spring, and a mounting groove is provided at the end of the rotating shaft 53. The spring leg at one end of the spring is clamped in the mounting groove, and the spring leg at the other end of the spring is hung on the side wall of the clutch boss 52.

[0095] In one embodiment, the inner opening linkage plate 4 includes a plate body 41 and a push arm 42 connected to the outer circumference of the plate body 41 , and the first locking member 1 is rotatably connected to the plate body 41 .

[0096] The push arm 42 and the second locking member 2 are matched with each other at an inclined surface, so as to drive the second locking member 2 to rotate in the unlocking direction under the driving of an external force.

[0097] When the inner opening linkage plate 4 rotates, the push arm 42 and the second locking member 2 are matched through the inclined surface. Compared with the inner opening linkage plate 4 being a flat plate, the setting of the push arm 42 can increase the contact area between the inner opening linkage plate 4 and the second locking member 2, and improve the stability of the inner opening linkage plate 4 when pushing the second locking member 2. Fig. 9 D in refs. refers to the motion envelope of the push arm 42.

[0098] In one embodiment, a through hole is provided on the inner opening linkage plate 4 , and the inner opening linkage plate 4 is mounted on the rotating shaft 53 of the first locking member 1 through the through hole.

[0099] In one embodiment, the push arm 42 extends along the rotation direction of the inner opening linkage plate 4, and an unlocking surface is provided on the second locking member 2, and the unlocking surface includes an inclined surface 22, and the inclined surface 22 is inclined toward the center of the plate body 41 in the direction in which the push arm 42 rotates close to the second locking member 2. The push arm 42 pushes the second locking member 2 to rotate through the inclined surface 22.

[0100] In one embodiment, if Figure 2 and Fig. 9 As shown, the unlocking surface also includes a stop surface 23, and the inclined surface 22 is connected to the stop surface 23. When the push arm 42 rotates to the stop surface 23, the push arm 42 stops pushing the second locking member 2 to rotate, so that the second locking member 2 remains in the unlocked state.

[0101] A movement gap is designed between the movement envelope of the push arm 42 and the stop surface 23 to absorb manufacturing tolerances, and preferably a reserved gap of ≥1.5 mm is provided. Fig. 9 F in the figure refers to the gap between the motion envelope of the push arm 42 and the stop surface 23 .

[0102] In one embodiment, if Figure 2 and Figure 3As shown, the door lock structure 100 further includes an inner opening arm 6 , which is rotatably connected to the first locking member 1 , and a third protruding structure 61 is provided on the inner opening arm 6 .

[0103] When the clutch boss 52 cooperates with the sliding surface 13, the third protruding structure 61 is connected to the clutch boss 52 in the circumferential direction of the first locking member 1, and the inner opening arm 6 is rotated by external force to drive the inner opening linkage plate 4 to rotate, and then the inner opening linkage plate 4 pushes the second locking member 2 to move in the unlocking direction to achieve unlocking of the door lock.

[0104] When the clutch boss 52 cooperates with the support surface 14, the third protruding structure 61 is disconnected from the clutch boss 52, so that when the inner opening arm 6 is rotated by an external force, the inner opening linkage plate 4 cannot be driven to rotate, and the door lock cannot be unlocked.

[0105] In one embodiment, the second protruding structure 44 is disposed on the plate body 41 , and the second protruding structure 44 is a plate body extending along the plane where the plate body 41 is located.

[0106] In one embodiment, an avoidance groove 45 is provided on the plate body 41 , and the avoidance groove 45 is used to avoid the fixed clamping platform 11 , so that the fixed clamping platform 11 passes through the avoidance groove 45 and is inserted into the clamping platform installation hole 32 .

[0107] In one embodiment, a rotating shaft 53 is provided on one side of the block body 51 close to the inner opening linkage plate 4 , and a clutch mounting hole 43 is provided on the plate body 41 , and the rotating shaft 53 is inserted into the clutch mounting hole 43 .

[0108] In one embodiment, the clutch boss 52 is connected to a side of the block body 51 close to the inner opening linkage plate 4 .

[0109] In one embodiment, two opposite side surfaces of the clutch boss 52 along the circumference of the first locking member 1 are parallel planes, and the planes on both sides can respectively make surface contact with the second protruding structure 44 and the third protruding structure 61 .

[0110] In one embodiment, the first locking member 1 is a super lock gear of a super lock mechanism, the output shaft of the super lock motor 102 is transmission connected to the first locking member 1, the second locking member 2 is a central control locking member of a central control lock mechanism, and the central control motor 101 drives the second locking member 2 to rotate.

[0111] There is a non-zero angle between the axis of the output shaft of the super lock motor 102 and the central axis of the first locking member 1. The output shaft of the super lock motor 102 drives the first locking member 1 to rotate through the worm 105. A section of the outer peripheral surface of the first locking member 1 is provided with gear teeth, and the worm 105 is meshed with the gear teeth.

[0112] In one embodiment, the central locking mechanism and the super locking mechanism are installed on the vehicle door, and a motor mounting housing is fixed on the vehicle door. The central control motor 101 and the super lock motor 102 are both installed on the motor mounting housing and sealed by a cover body, and the fixed axis of the first locking member 1 is fixed on the motor mounting housing.

[0113] It should be noted that since the central control release and insurance functions are often used, they need to meet the durability requirements of more than 10,000 times, while the application requirements of the super lock mechanism are relatively small. Therefore, when the door lock structure 100 changes from the fully locked insurance state to the released insurance state, the preferred control logic strategy is to first power the super lock motor 102 to release the super lock insurance, and then power the central control motor 101 to release the central control insurance, so as to improve and ensure the service life of the central control locking mechanism.

[0114] In other embodiments, the coupling hole 31 and the first protruding structure 21 may be omitted, and a fourth protruding structure may be provided on the linkage rod 3, the side of the fourth protruding structure close to the second locking member 2 being an inclined surface 22 or an arcuate surface, and when the second locking member 2 moves in the release direction, the second locking member 2 gradually approaches the inclined surface 22 or the arcuate surface of the fourth protruding structure until they overlap. Of course, the first protruding structure 21 may also be provided on the second locking member 2, so that the second locking member 2 directly drives the first locking member 1 to move in the release direction.

[0115] In other embodiments, the first protruding structure 21 may be a block, a column or other irregular shapes.

[0116] In other embodiments, the linkage rod 3 can be connected to the outer peripheral surface of the first locking member 1. In this case, the linkage rod 3 may include a first rod portion and a second rod portion which are arranged at an angle, one end of the first rod portion is connected to one end of the second rod portion, the central control connecting portion is arranged at the other end of the first rod portion, and the super locking portion is arranged on the second rod portion.

[0117] In other embodiments, the linkage rod 3 may be hinged on an axial end surface of the first locking member 1 .

[0118] In other embodiments, the inner opening linkage plate 4 may only include the plate body 41 . In this case, the inclined surface between the inner opening linkage plate 4 and the second locking member 2 may be provided on the second locking member 2 or on the outer peripheral surface of the plate body 41 .

[0119] In other embodiments, an inclined surface 22 may be provided on the outer peripheral surface of the push arm 42 facing the second locking member 2 , and the inclined surface 22 is inclined in a direction away from the center of the inner opening linkage plate 4 along the rotation direction of the push arm 42 .
