The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] As an important part of the car, car door locks bear the arduous task of safety and reliability. In the continuous development process of car door locks in recent years, the door locks configured on the side doors of mid-to-high-end models of mainstream car companies have done a lot of work on the structural design of the inner opening rocker arm to achieve the inner pull unlocking function under different door lock working conditions. However, the structural design of the existing inner opening rocker arm has the disadvantages of occupying a large installation space; the rotating rocker arm is long and occupies a large rotating space; there are many transmission parts and a complex structure.

[0044] Reference below Figure 1-Figure 9 A door lock assembly according to an embodiment of the present utility model is described.

[0045] According to the utility model, the door lock assembly 1 includes a lock housing 11, a first rocker arm 12, a second rocker arm 13 and an unlocking portion 14, the first rocker arm 12 is provided with a first pivot axis and is rotatably arranged on the lock housing 11 around the first pivot axis to selectively unlock the door lock assembly 1; the second rocker arm 13 is provided with a second pivot axis and is rotatably arranged on the lock housing 11 around the second pivot axis, the first pivot axis is coaxial with the second pivot axis and the second rocker arm 13 and the first rocker arm 12 are at least partially overlapped in the axial direction; the unlocking portion 14 is arranged on the lock housing 11 and cooperates with the second rocker arm 13; wherein, a sliding matching portion that slides relative to the unlocking portion 14 is formed on the second rocker arm 13 so as to be suitable for the unlocking portion 14 to move relative to the second rocker arm 13 to switch between an unsecured state and an secured state, and in the unsecured state, the unlocking portion 14 is suitable for driving the first rocker arm 12 to rotate under the drive of the second rocker arm 13 to unlock the door lock assembly 1.

[0046] According to the door lock assembly 1 of the utility model, a lock housing 11 is constructed as a supporting structure of the door lock as a whole, and a first rocker arm 12 and a second rocker arm 13 are rotatably arranged on the lock housing 11, wherein a first pivot shaft is arranged on the first rocker arm 12, the first pivot shaft is connected to the housing, and the first rocker arm 12 can rotate around the first pivot shaft; a second pivot shaft is arranged on the second rocker arm 13, the second pivot shaft is connected to the housing, and the second rocker arm 13 can rotate around the second pivot shaft. The arrangement of the first pivot shaft and the second pivot shaft can avoid mutual interference between the first rocker arm 12 and the second rocker arm 13 when rotating.

[0047] During assembly, the first pivot axis on the first rocker arm 12 is coaxially arranged with the second pivot axis on the second rocker arm 13, and the first rocker arm 12 and the second rocker arm 13 at least partially overlap in the axial direction. The assembly method of the first rocker arm 12 and the second rocker arm 13 can improve the compactness of the structure of the door lock assembly 1, reduce the space occupied by the first rocker arm 12 and the second rocker arm 13, and reduce the volume of the door lock.

[0048] The first rocker arm 12 can unlock the door lock assembly 1 by rotating a certain angle, and the second rocker arm 13 can be used to drive or drive the first rocker arm 12 to move. Specifically, the lock housing 11 is also provided with an unlocking portion 14, which cooperates with the second rocker arm 13, and the second rocker arm 13 is provided with a sliding matching portion, and the unlocking portion 14 can cooperate with the sliding matching portion, for example, the sliding matching portion can be configured as a slide groove, and at least part of the structure on the unlocking portion 14 can be accommodated in the slide groove and slide in the slide groove to achieve relative movement between the unlocking portion 14 and the second rocker arm 13. After the relative movement between the unlocking portion 14 and the second rocker arm 13 occurs, the unlocking portion 14 can switch between the unsecured state and the secured state, wherein the unsecured state can be simply understood as in this state, the unlocking portion 14 can drive the first rocker arm 12 to rotate to achieve the unlocking function; the secured state can be simply understood as in this state, the unlocking portion 14 cannot drive the first rocker arm 12 to rotate to achieve the unlocking function.

[0049] In some embodiments, the insurance state of the unlocking part 14 can be reported in two situations: one is that the unlocking part 14 and the first rocker arm 12 are not linked temporarily. At this time, the unlocking part 14 cannot drive the first rocker arm 12 to rotate; the other is that the unlocking part 14 is limited by other structures of the door lock assembly 1 and cannot move. At this time, no matter how the second rocker arm 13 rotates, it is impossible to achieve the operation of driving the unlocking part 14 to drive the first rocker arm 12 to rotate.

[0050] When in use, if the unlocking portion 14 is in the released state, at this time, the second rocker arm 13 drives the unlocking portion 14 to move by its own rotation, and the movement of the unlocking portion 14 can drive the first rocker arm 12 to rotate, and the door lock can be unlocked after the first rocker arm 12 rotates; if the unlocking portion 14 is in the first case in the secured state, the second rocker arm 13 drives the unlocking portion 14 to move by its own rotation and drives the first rocker arm 12 to rotate to the released state, after the unlocking portion 14 is in the released state, the second rocker arm 13 is reset and drives the unlocking portion 14 to rotate again by rotation, and the rotation of the unlocking portion can drive the first rocker arm 12 to rotate to achieve unlocking; if the unlocking portion 14 is in the second case in the secured state, it is necessary to first contact the restrictions of other structures in the door lock assembly 1 on the unlocking portion 14 and then repeat the operating steps of the first case.

[0051] The door lock assembly 1 realizes the unlocking function of the door lock by the cooperation between the first rocker arm 12, the second rocker arm 13 and the unlocking part 14. The overall structure is simple and convenient for layout, which improves the practicality of the door lock assembly 1. At the same time, the insurance state of the unlocking part 14 can provide a layer of protection for the door lock assembly 1, avoid mis-locking, and improve the safety of the door lock assembly 1.

[0052] According to one embodiment of the utility model, the unlocking portion 14 includes a first linkage 141, on which is formed a first driving end 1411 suitable for cooperating with the first rocker arm 12, and the first driving end 1411 is movably arranged on the second rocker arm 13 to switch between a first position and a second position. When the first driving end 1411 moves to the first position, the unlocking portion 14 is in a released state, and the first linkage 141 can selectively drive the first rocker arm 12 to rotate under the drive of the second rocker arm 13.

[0053] Since the unlocking part 14 is a structure in the door lock assembly 1 for driving the first rocker arm 12 to unlock the door lock assembly 1, the structure of the unlocking part 14 will affect the use of the door lock assembly 1. The unlocking part 14 is provided with a first linkage 141, and a first driving end 1411 is formed on the first linkage 141. The first driving end 1411 is movably provided on the second rocker arm 13 and is suitable for cooperating with the first rocker arm 12. When the door lock assembly 1 is working, the second rocker arm 13 moves and drives the first driving end 1411 to rotate. The first driving end 1411 can drive the first rocker arm 12 to rotate in certain circumstances so that the first rocker arm 12 can unlock the door lock assembly 1.

[0054] Specifically, the first driving end 1411 can switch between the first position and the second position on the second rocker arm 13. When the first driving end 1411 moves to the first position, the first driving end 1411 can cooperate with the first rocker arm 12. At this time, the unlocking portion 14 is in the unsecured state. The first linkage member 141 can drive the first rocker arm 12 to rotate under the drive of the second rocker arm 13 to unlock the door lock assembly 1. The specific situation here can be understood as the door lock assembly 1 is in the lower secure state. When the door lock assembly 1 is in the lower secure state, the first driving end 1411 can drive the first rocker arm 12 to rotate to unlock. When the door lock assembly 1 is in the upper secure state, the first driving end 1411 cannot drive the first rocker arm 12 to rotate and thus cannot unlock. The two different states of cooperation between the first driving end 1411 and the first rocker arm 12 can avoid the door lock assembly 1 from being locked by mistake, thereby improving the safety of the door lock assembly 1.

[0055] According to one embodiment of the utility model, a first matching groove 131 suitable for accommodating the first driving end 1411 is formed on the second rocker arm 13, the first position is located on the side of the first matching groove 131 close to the second pivot axis, and the second position is located on the side of the first matching groove 131 away from the second pivot axis. A connecting groove suitable for matching with the first driving end 1411 is formed on the first rocker arm 12, and the first driving end 1411 is embedded in the connecting groove after the first driving end 1411 moves to the first position.

[0056] Since the first driving end 1411 and the second rocker arm 13 have a matching relationship between the first position and the second position, the structure of the second rocker arm 13 will affect the matching between the first driving end 1411 and the first rocker arm 12. Specifically, a first matching groove 131 suitable for receiving the first driving end 1411 is formed on the second rocker arm 13, and at least a portion of the first driving end 1411 can be received in the first matching groove 131 and can move along the extension direction of the first matching groove 131. Among them, the side of the first matching groove 131 close to the second pivot axis is the first position, and the side of the first matching groove 131 away from the second pivot axis is the second position. When the second rocker arm 13 moves, the first driving end 1411 can reciprocate between the first position and the second position. When the door lock assembly 1 needs to be unlocked, the first driving end 1411 can enter the first position and be embedded in the connecting groove on the first rocker arm. At this time, the movement of the second rocker arm 13 can drive the first linkage 141 to move, and the first linkage 141 can drive the first rocker arm 12 to rotate to unlock the door lock assembly 1. The structure of the first matching groove 131 realizes the switching of the first driving end 1411 between the first position and the second position, which is convenient for controlling the cooperation between the first linkage 141 and the first rocker arm 12.

[0057] According to one embodiment of the utility model, the unlocking portion 14 also includes a crank 143, which is rotatably disposed on the lock housing 11, and the crank 143 is provided with a first matching portion, which cooperates with the first linkage member 141 to limit the first driving end 1411 from moving from the second position to the first position. A first matching portion is provided on the crank 143, and the first matching portion can cooperate with the first linkage 141 to limit the movement of the first driving end 1411 between the second position and the first position. Specifically, when the second rocker arm 13 rotates, the first linkage 141 moves, and the first driving end 1411 moves in the first matching groove 131. At this time, the crank 143 does not rotate, and the door lock assembly 1 is in an upper insurance state. The first matching portion cooperates with the first linkage 141 to limit the first driving end 1411 from moving to the first position, and the first linkage 141 cannot cooperate with the first rocker arm 12; when the crank 143 rotates, the door lock assembly 1 is converted into a lower insurance state, the first driving end 1411 can move to the first position and cooperate with the first rocker arm 12, and the first linkage 141 can drive the first rocker arm 12 to unlock the door lock assembly 1 under the drive of the second rocker arm 13. It can be simply understood that the crank 143 can control whether the unlocking part 14 can complete the unlocking process. The setting of the crank 143 provides a layer of protection for the unlocking process, avoids misunderstanding of the locking operation, and improves the safety of the door lock.

[0058] According to one embodiment of the utility model, the unlocking part 14 also includes a second linkage 142, one end of which can move relative to the lock housing 11, the other end of the second linkage 142 is hinged to the second rocker arm 13, and a second driving end 1421 is provided on the second linkage 142, and the second driving end 1421 is suitable for driving the crank 143 to rotate to release the movement restriction of the driving end by the first matching part.

[0059] Since the crank 143 can selectively limit the movement of the first drive end 1411, the structure of the unlocking part 14 will affect the control of the crank 143 over the unlocking process. The unlocking part 14 is also provided with a second linkage 142, one end of which can move relative to the lock housing 11, and the other end of the second linkage 142 is slidably connected to the second rocker arm 13, a slide groove is formed on the second rocker arm 13, and a slider that slides in the slide groove of the second rocker arm is formed on the second rocker arm 13. When the second rocker arm 13 rotates, the second linkage 142 can be driven by the second rocker arm 13 to move, and the second linkage 142 is also formed with a second drive end 1421, which can selectively cooperate with the crank 143 to drive the crank 143 to move. Specifically, when the second rocker arm 13 rotates, the second linkage 142 can be driven by the second rocker arm 13 to move. After the arm 13 rotates, the first linkage 141 and the second linkage 142 simultaneously follow the second rocker arm 13 to move. When the second linkage 142 moves to a certain position, the second drive end 1421 can cooperate with the crank 143. At this time, the second linkage 142 can drive the crank 143 to rotate. When the crank 143 rotates a certain angle, the first matching part will also rotate a certain angle. At this time, the door lock assembly 1 is converted from the upper insurance state to the lower insurance state. At this time, the first drive end 1411 can cooperate with the first rocker arm 12 so that the first linkage 141 drives the first rocker arm 12 to rotate and thus realize the unlocking process. The certain angle here can be set according to actual conditions, as long as it does not affect the movement of other structures and does not increase the occupied space of the crank 143. The setting of the second linkage 142 makes the rotation of the crank 143 controllable, thereby realizing the conversion of the door lock assembly 1 between the upper insurance state and the lower insurance state.

[0060] According to one embodiment of the utility model, a first radial extension portion 1431 and a second radial extension portion 1432 are formed on the outer periphery of the crank 143, and a first boss 1412 protruding in the thickness direction is formed on the first linkage member 141, and the first radial extension portion 1431 is configured as a first matching portion and abuts against the outer periphery of the first boss 1412; the second radial extension portion 1432 and the first radial extension portion 1431 are spaced apart in the circumferential direction of the crank 143, and a second boss protruding in the thickness direction is formed on the second linkage member 142, and the second boss is configured as a second driving end 1421 and is suitable for abutting against the second radial extension portion 1432 to drive the crank 143 to rotate.

[0061] Since the crank 143 has a corresponding matching relationship with the first linkage 141 and the second linkage 142, the structure of the crank 143 will affect the conversion of the door lock assembly 1 between the upper safety state and the lower safety state. Specifically, the outer periphery of the crank 143 is formed with a first radial extension portion 1431 and a second radial extension portion 1432 spaced from each other, and at the same time, a first boss 1412 is formed on the first linkage 141, and a second boss is formed on the second linkage 142, wherein the first boss 1412 protrudes in the thickness direction of the first linkage 141 and can stop against the outer periphery of the first radial extension portion 1431, and the first radial extension portion 1431 here can be understood as the first matching portion in the above embodiment; the second boss protrudes in the thickness direction of the second linkage 142 and can stop against the outer periphery of the second radial extension portion 1432, and the second boss here can be understood as the second driving end 1421 in the above embodiment.

[0062] During operation, the second rocker arm 13 rotates, and the first linkage 141 and the second linkage 142 follow the movement of the second rocker arm 13. The first boss 1412 on the first linkage 141 moves along the first radial extension portion 1431 toward the direction close to the crank 143, and the second boss on the second linkage 142 moves toward the direction close to the second radial extension portion 1432. When the second boss and the second radial extension portion 1432 stop, the second linkage 142 can drive the crank 143 to rotate. When the crank 143 rotates a certain angle, the second rocker arm 13 rotates again to drive the first linkage 141, so that the first driving end 1411 can enter the first position and cooperate with the first rocker arm 12. At this time, the first linkage 141 can drive the first rocker arm 12 to move to unlock the door lock assembly 1. The structure of the crank 143 enables the first linkage 141 and the second linkage 142 to cooperate with the corresponding structures on the crank 143 respectively to control the unlocking process, ensuring the normal use of the door lock assembly 1, so that the second rocker arm 13 is rotated for the first time to rotate the crank 143 to the lower safety state, and then the second rocker arm 13 is rotated again so that the second rocker arm 13 can drive the first linkage 141 to drive the first rocker arm 12 to achieve unlocking.

[0063] According to an embodiment of the present invention, the door lock assembly 1 further comprises a clutch device 15, which is rotatably disposed on the lock housing 11, and one end of the second linkage member 142 is rotatably disposed on the clutch device 15, and the clutch device 15 is adapted to drive the second linkage member 142 to rotate, so as to drive the second boss to separate from the second radial extension portion 1432 and / or the clutch device 15 to rotate until it abuts against the crank 143 to limit the rotation of the crank 143. Since the rotation of the crank 143 will affect the switching between the upper safety state and the lower safety state of the door lock assembly 1, the door lock assembly 1 needs to be constructed with a structure capable of limiting the movement of the crank 143 to avoid the crank 143 from moving too far and affecting the use of the door lock assembly 1. Specifically, the door lock assembly 1 is also provided with a clutch device 15, which is rotatably arranged on the lock housing 11, and one end of the second linkage member 142 is rotatably arranged on the clutch device 15. When the second rocker arm 13 rotates, the second linkage member 142 can be driven by the second rocker arm 13 to rotate with the connection position between the second linkage member 142 and the clutch device 15 as the axis. At the same time, when the clutch device 15 itself rotates, it can also drive the second linkage member 142 to move. For example, when the clutch device 15 rotates toward the crank 143, the second linkage member 142 is driven by the clutch device 15 to move toward the rotation axis close to the second rocker arm 13. It is worth noting that the rotation of the clutch device 15 toward the crank 143 can be understood as Figure 1 The clutch device 15 shown in the figure rotates counterclockwise. When the clutch device 15 rotates toward the crank 143 by a certain angle, the second linkage member 142 is disengaged from the crank 143 under the drive of the clutch device 15, and the second boss is located radially outside the second radial extension portion 1432, so that the second boss cannot stop against the second radial extension portion 1432. At this time, the rotation of the second linkage member 142 will not drive the crank 143 to rotate, and at the same time, at least part of the edge of the clutch device 15 can stop against at least part of the edge of the crank 143, and the crank 143 cannot rotate, that is, the crank 143 cannot be converted from the upper insurance state to the lower insurance state, and the door lock is always in the locked state. The setting of the clutch device 15 can keep the door lock in a locked state under certain circumstances, which can avoid misunderstanding of the locking operation and improve the safety of the door lock assembly 1.

[0064] According to one embodiment of the present utility model, the clutch device 15 includes a worm wheel 151 and a worm 152, the worm wheel 151 is rotatably disposed on the lock housing 11, and one end of the second linkage member 142 is rotatably disposed on the worm wheel 151; the worm 152 is suitable for connecting with the driving member 153 and suitable for driving the worm wheel 151 to rotate. The clutch device 15 is provided with a worm wheel 151 and a worm 152. The worm wheel 151 is rotatably arranged on the lock housing 11. The worm 152 is meshed with the worm wheel 151 and a driving member 153 can be arranged at one end of the worm 152. When the clutch device 15 is working, the driving member 153 starts to drive the worm 152 to rotate. The worm 152 transmits the torque to the worm wheel 151 to rotate the worm wheel 151. After the worm wheel 151 rotates, it drives the second linkage member 142 to move, thereby realizing the control of the door lock assembly 1 by the clutch device 15. In addition, the setting mode of the worm wheel 151 and the worm 152 can only realize the one-way output from the worm 152 to the worm wheel 151, thereby preventing the worm wheel 151 from rotating under the drive of the crank 143, and making the control of the clutch device 15 more reliable and stable.

[0065] According to an embodiment of the present invention, the door lock assembly 1 further comprises a locking portion 16, which is movably disposed on the lock housing 11, and one end of the first linkage 141 is hinged to the locking portion 16, and the locking portion 16 can be selectively moved to drive the first linkage 141 to move, so as to keep the driving end in the second position. In the embodiment, the end of the first linkage 141 is rotatably connected to the locking portion 16. The locking portion 16 is rotatably disposed on the lock housing 11, and the rotation of the locking portion 16 will affect the matching relationship between the first linkage 141 and the first rocker arm 12. Figure 1 As shown, when the locking portion 16 rotates counterclockwise, the first linkage member 141 will move in a direction away from the first rocker arm 12 under the drive of the locking portion 16. At this time, the driving end will always be in the second position. No matter how the second rocker arm 13 moves, the first linkage member 141 cannot drive the first rocker arm 12 to unlock the door lock assembly 1. It can also be understood that the door lock assembly 1 is always in the insurance state at this time. The setting of the locking portion 16 can make the door lock assembly 1 have an insurance function, avoid the door lock from being opened by mistake, and improve the safety of the door lock assembly 1.

[0066] According to an embodiment of the utility model, the locking portion 16 includes a support plate 161, which is rotatably disposed on the lock housing 11, and a second matching groove 1611 extending in the circumferential direction is formed on the support plate 161, and a third boss 1413 accommodated in the second matching groove 1611 is formed on the first linkage member 141. Since one end of the first linkage member 141 is connected to the locking portion 16, the structure of the locking portion 16 will affect the movement of the first linkage member 141. Specifically, the locking portion 16 is provided with a support plate 161, which is rotatably disposed on the lock housing 11, and a second matching groove 1611 is formed on the support plate 161, and a third boss 1413 is formed on the first linkage member 141. During assembly, the third boss 1413 is accommodated in the second matching groove 1611 and can slide in the third matching groove. The third matching groove facilitates the relative movement between the first linkage member 141 and the locking portion 16 , so that the locking portion 16 can drive the first linkage member 141 to move together without affecting the movement of the first linkage member 141 itself, thereby ensuring the freedom and range of motion of the first linkage member 141 .

[0067] According to an embodiment of the utility model, the locking part 16 also includes an elastic member 162, which is arranged on the support plate 161 and is suitable for keeping the first linkage member 141 and the first matching portion in abutment. During assembly, the locking part 16 is also provided with an elastic member 162 on the support plate 161, and the elastic member 162 can abut against the third boss 1413 to drive the first linkage member 141 to maintain a fitting relationship with the first matching portion. When the crank 143 rotates, the structure of the elastic member 162 can make the first linkage member 141 also fit with the first matching portion during movement, which is convenient for the crank 143 to control the first linkage member 141. And when the locking part 16 rotates, due to the matching relationship between the third matching groove and the third boss 1413, the elastic member 162 will not affect the separation of the first linkage member 141 from the crank 143, and can keep the first linkage member 141 stable.

[0068] According to an embodiment of the present utility model, the door lock assembly 1 further includes a central control wheel 17, which is rotatably disposed on the lock housing 11 and is coaxially disposed with the first pivot axis. During assembly, the door lock assembly 1 may further be provided with a central control wheel 17, which is rotatably disposed on the lock housing 11 and is coaxially disposed with the first pivot axis, that is, the central control wheel 17 is coaxially arranged with the first rocker arm 12 and the second rocker arm 13 and at least partially overlaps in the axial direction. The coaxial arrangement of the central control wheel 17 with the first rocker arm 12 and the second rocker arm 13 can improve the compactness of the structure of the door lock assembly 1 and reduce the occupied space.

[0069] In some embodiments, the door lock assembly 1 may also be provided with a pull wire 101, which may be connected to the second rocker arm 13. By driving the second rocker arm 13 to move through the pull wire 101, the force driving the second rocker arm 13 to move can be reduced, making the unlocking process of the door lock assembly 1 more labor-saving.
