[0049] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0050] In the related art, when a car door lock is provided with a super lock, the function is single and it can only realize the opening and closing of the super lock function, and the linkage with the central lock part is poor. Therefore, it is necessary to improve the door lock structure and increase the functionality of the super lock.

[0051] Reference below Figure 1-Figure 10 A door lock assembly 1 according to an embodiment of the present invention and a vehicle 10 having the door lock assembly 1 are described.

[0052] Reference Figure 1-Figure 3 As shown, the door lock assembly 1 according to the utility model comprises an unlocking rocker arm 12, an inner opening rocker arm 13, an unlocking portion 14 and a super lock device 15. The unlocking portion 14 cooperates with the inner opening rocker arm 13, and the unlocking portion 14 is suitable for driving the unlocking rocker arm 12 to rotate to unlock the lock tongue under at least two drives of the inner opening rocker arm 13. The super lock device 15 can selectively drive the unlocking portion 14 to the upper safety position.

[0053] According to the door lock assembly 1 of the utility model, the super lock device 15 can control the unlocking part 14 to the upper safety position, so that the unlocking part 14 cannot move to trigger the inner opening rocker arm 13, and the opening and closing of the super lock device 15 can realize the action of the electric upper central control safety. After the super lock device 15 is unlocked, the unlocking rocker arm 12 is driven at least twice to make the unlocking part 14 unlock the lock tongue, realizing the double-pull unlocking function. In this way, the linkage and functionality of the various components of the door lock assembly 1 are increased, and the functional integration is higher. It can further improve the safety and anti-theft performance of the door lock assembly 1.

[0054] In some embodiments, Figure 3 and Figure 4 As shown, the unlocking portion 14 includes an inner opening clutch rod 141 and an inner opening crank 143 .

[0055] The inner opening clutch rod 141 is movably arranged on the inner opening rocker arm 13 to switch between the unlatched position and the upper safety position. When in the unlatched position, the inner opening clutch rod 141 can drive the unlocking rocker arm 12 to rotate under the drive of the inner opening rocker arm 13 to unlock the lock tongue. When in the upper safety position, the inner opening clutch rod 141 is separated from the unlocking rocker arm 12. The inner opening crank 143 is rotatable, and when the inner opening crank 143 rotates in a first direction, it drives the inner opening clutch rod 141 to move to the upper safety position. The super lock device 15 can selectively drive the inner opening crank 143 to rotate in the first direction.

[0056] By dividing the unlocking part 14 into at least an inner clutch rod 141 and an inner crank 143, the super lock device 15 can drive the inner crank 143 to rotate to determine whether the inner clutch rod 141 is released and whether it can be driven twice by the inner rocker arm 13. In this way, the super lock device 15 can achieve many subsequent actions through the rotation of the inner crank 143. The inner crank 143 serves as a rotating body and multiple contacts can be distributed on its outer periphery to trigger the action of other parts, thereby further improving the functional integration of the door lock assembly 1. There is no need to set up too many scattered parts for assembly, which is also beneficial to improving transmission reliability, door lock safety, and structural linkage.

[0057] Specifically, Figure 3 and Figure 4 As shown, the door lock assembly 1 further includes: an outer opening clutch rod 18 and a locking link 19. The outer opening clutch rod 18 can rotate to drive the unlocking rocker arm 12 to rotate to unlock the lock tongue. One end of the locking link 19 is hingedly connected to the inner opening crank 143. When the inner opening crank 143 rotates in a first direction, it drives the locking link 19 to move. When the locking link 19 moves, it pushes the outer opening clutch rod 18 to separate from the unlocking rocker arm 12. In other words, when the outer opening clutch rod 18 is triggered, it can be unlocked by rotating the unlocking rocker arm 12, which increases the unlocking method of the door lock assembly 1. For example, on a vehicle, the inner opening rocker arm 13 can be triggered by pulling the inner opening pull wire 101, and the outer opening clutch rod 18 can be triggered by pulling the outer opening pull wire. This door lock assembly 1 can be opened both inside and outside, that is, the vehicle door can be opened from the inside or from the outside.

[0058] In some specific embodiments, the door lock assembly 1 further includes a lock housing 11 , and the aforementioned various parts are all mounted on the lock housing 11 , and the lock housing 11 is both a supporting housing and a protective housing.

[0059] Specifically, the unlocking rocker arm 12 is rotatably arranged on the lock housing 11 to selectively unlock the lock tongue. Specifically, the unlocking rocker arm 12 is connected to the lock housing 11 through a pin shaft, rotates with the pin shaft as a pivot axis, and drives the transmission mechanism through rotation to realize the unlocking of the lock tongue.

[0060] The inner opening rocker arm 13 is rotatably disposed on the lock housing 11. Specifically, the inner opening rocker arm 13 is connected to the lock housing 11 via another pin shaft and can be rotated using the pin shaft as a pivot axis.

[0061] The inner opening clutch rod 141 is movably arranged on the inner opening rocker arm 13 to switch between the unlatched position and the on-safety position. In the unlatched position, the inner opening clutch rod 141 can drive the unlocking rocker arm 12 to rotate under the drive of the inner opening rocker arm 13 to unlock the lock tongue. In the on-safety position, the inner opening clutch rod 141 is separated from the unlocking rocker arm 12, and the inner opening clutch rod 141 cannot drive the unlocking rocker arm 12 to rotate.

[0062] The inward crank 143 is rotatably disposed on the lock housing 11 .

[0063] The outward opening clutch rod 18 is rotatably disposed on the lock housing 11 to drive the unlocking rocker arm 12 to rotate to unlock the lock tongue.

[0064] The locking link 19 has one end hingedly connected to the inner crank 143. When the inner crank 143 rotates in a first direction, it drives the locking link 19 to move, and drives the inner clutch rod 141 to move to the upper safety position. When the locking link 19 moves, it pushes the outer clutch rod 18 to separate from the unlocking rocker arm 12.

[0065] The super lock device 15 is arranged on the lock housing 11. The super lock device 15 can selectively drive the inner opening crank 143 to rotate along the first direction. When the inner opening crank 143 rotates along the first direction, it is suitable to drive the inner opening clutch rod 141 to move to the upper safety position. At this time, even if the inner opening rocker arm 13 is rotated, the inner opening clutch rod 141 cannot move to the unsafe position, thereby shielding the unsafe function.

[0066] It should be noted that the “first direction” can be clockwise or counterclockwise. Figure 2 , Figure 4 , Figure 5 , Figure 7 In the above, the “first direction” refers to the counterclockwise direction. Figure 3 , Figure 6 , Figure 8 and Fig. 9 In the description, the “first direction” refers to the clockwise direction. The “second direction” mentioned below is the opposite direction of the “first direction”. When the “first direction” is the clockwise direction, the “second direction” is the counterclockwise direction; when the “first direction” is the counterclockwise direction, the “second direction” is the clockwise direction.

[0067] Specifically, Figures 4 to 6 The action process of the door lock assembly 1 shown is taken as an example for a brief description.

[0068] Figure 4 The initial position of the central lock is shown. At this time, the central lock is in the release state, the locking link 19 is in the right action position, and the locking link 19 releases the outer clutch rod 18, so that the outer clutch rod 18 can trigger the unlocking rocker arm 12 to rotate to unlock the lock tongue. The inner clutch rod 141 is in the left action position, and the inner clutch rod 141 is combined with the unlocking rocker arm 12, so that the inner rocker arm 13 can trigger the unlocking rocker arm 12 to rotate to unlock the lock tongue through the inner clutch rod 141. If the door lock is also equipped with an inner pull wire or an outer pull wire as a mechanical backup, the inner pull wire can be used to pull the inner rocker arm 13 to trigger unlocking, and the outer pull wire can be used to pull the outer clutch rod 18 to trigger unlocking.

[0069] like Figure 5 and Figure 6 As shown, when the door lock assembly 1 receives the signal of the electric central control safety lock, the super lock device 15 is activated and drives the inner crank 143 to rotate counterclockwise (rotate in the first direction). Figure 5 The crank 143 in the middle rotates counterclockwise (in Figure 6 At the same time, after the inner opening crank 143 rotates counterclockwise, it drives the inner opening clutch rod 141 to move left to the upper safety position, and the inner opening clutch rod 141 moves left to push the outer opening clutch rod 18 away, so that the outer opening clutch rod 18 is separated from the unlocking rocker arm 12, so that the outer opening clutch rod 18 cannot trigger the unlocking rocker arm 12 to rotate to unlock the lock tongue during rotation, and the outer pulling failure is realized. At the same time, after the inner opening crank 143 rotates counterclockwise, it drives the inner opening clutch rod 141 to move right, so that the inner opening clutch rod 141 is separated from the unlocking rocker arm 12, so that the inner opening rocker arm 13 cannot trigger the unlocking rocker arm 12 to rotate to unlock the lock tongue through the inner opening clutch rod 141 during rotation, and the inner pulling failure is realized. Figure 6 In the embodiment, after the inner opening crank 143 rotates clockwise, the inner opening clutch rod 141 is driven to move leftward, and the inner opening clutch rod 141 is separated from the unlocking rocker arm 12. The inner opening rocker arm 13 cannot trigger the unlocking rocker arm 12 to rotate through the inner opening clutch rod 141 during rotation.

[0070] Then as Figure 7 As shown, the super lock device 15 is reset to the initial position, at which time the central control insurance is locked and the super lock is in the closed state.

[0071] When the super lock signal is received, the super lock device 15 has returned to the initial position and remains motionless. At this time, the locking link 19 cannot be reset, the door lock central control insurance cannot be released, and the mechanical inside and outside unlocking of the door fails.

[0072] This can shield the release function, which is beneficial to improving the safety of the door lock assembly 1.

[0073] During assembly, the pivot axis of the unlocking rocker arm 12 is coaxially arranged with the pivot axis of the inner opening rocker arm 13, and the inner opening clutch rod 141 and the inner opening crank 143 are arranged on the outer periphery of the inner opening rocker arm 13. The arrangement of the unlocking rocker arm 12 and the inner opening rocker arm 13 can improve the compactness of the structure of the door lock assembly 1, reduce the space occupied by the unlocking rocker arm 12 and the inner opening rocker arm 13, and realize the unlocking function of the door lock through the cooperation between the two rock arms and the inner opening clutch rod 141 and the inner opening crank 143. The overall structure is simple and easy to arrange, thereby improving the practicability of the door lock assembly 1.

[0074] The pivot axis of the unlocking rocker arm 12 is coaxially arranged with the pivot axis of the inner opening rocker arm 13 , thereby making the structure of the door lock assembly 1 compact.

[0075] In some embodiments of the present invention, Figure 2-Figure 5As shown, the super lock device 15 includes a worm wheel 151 and a worm 152. The worm wheel 151 is rotatably arranged on the lock housing 11, and the inner crank 143 is rotatably arranged on one side of the worm wheel 151 so that the worm wheel 151 can abut against or disengage from the inner crank 143; the worm 152 is suitable for being connected to the driving member 153 and suitable for driving the worm wheel 151 to rotate. The super lock 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 super lock 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 can selectively drive the inner opening crank 143 to rotate. When the inner opening crank 143 rotates, it can drive the super lock clutch rod 142 to move, thereby realizing the control of the door lock assembly 1 by the super lock device 15.

[0076] In addition, the arrangement of the worm wheel 151 and the worm 152 can only achieve one-way output from the worm 152 to the worm wheel 151, preventing the worm wheel 151 from rotating under the drive of the inner crank 143, making the control of the super locking device 15 more reliable and stable.

[0077] In some specific embodiments, Figure 4 and Figure 5 As shown, the inner crank 143 has a switchable first position and a second position. Figure 5 The inner crank 143 is shown in the first position. Figure 4 The inwardly opened crank 143 is shown in the second position.

[0078] A main extension portion 1433 is formed on the outer periphery of the inner crank 143, and the main extension portion 1433 is hingedly connected to the locking link 19. The side of the main extension portion 1433 facing the worm gear 151 forms an extended side surface 14331, and the side of the main extension portion 1433 away from the pivot axis of the inner crank 143 forms an extended end surface 14332.

[0079] When the inner crank 143 is driven to rotate in the first direction to the first position, one end of the worm wheel 151 abuts against the extended side surface 14331. When the inner crank 143 is driven to rotate in the second direction to the second position, one end of the worm wheel 151 abuts against the extended end surface 14332.

[0080] By using the main extension part 1433 formed on the outer periphery of the inner crank 143, the size of the inner crank 143 can be reduced, thereby improving compactness. Moreover, when the worm gear 151 drives the inner crank 143 to switch between two positions, it abuts against the extended side surface 14331 and the extended end surface 14332 thereof, respectively, so that the angle variation range of the inner crank 143 at the two positions is large, which is conducive to driving the obvious movement of related parts and improving the operational reliability.

[0081] Specifically, the extended side surface 14331 is an arc-shaped concave surface. When the inward crank 143 reaches the first position and one end of the worm wheel 151 abuts against the extended side surface 14331, the arc-shaped concave surface is used to help maintain the stability of the abutment.

[0082] The extended side surface 14331 is an arc-shaped concave surface, and the extended end surface 14332 is an arc-shaped convex surface, and the extended side surface 14331 and the extended end surface 14332 are connected by an arc transition. This arrangement is conducive to improving the smoothness of the movement of the surface contact point between the worm gear 151 and the main extension part 1433, improving the smoothness of the movement, and reducing the risk of jamming.

[0083] In some specific embodiments, Figure 3 As shown, the door lock assembly 10 further includes: an inner opening elastic member 1438, which is connected to the inner opening crank 143 and is used to drive the main extension 1433 to abut against the worm gear 151. Thus, a stuck gap between the inner opening crank 143 and the worm gear 151 can be effectively avoided, which is conducive to ensuring the smoothness of the action.

[0084] Optionally, the inwardly opening elastic member 1438 may be a spring or a torsion spring.

[0085] In some embodiments of the present invention, Figure 2 As shown, the door lock assembly 1 further includes an outward opening elastic member 184, and the outward opening clutch rod 18 is pressed against the locking link 19 under the elastic force of the outward opening elastic member 184 to ensure the reliability of transmission. Optionally, the outward opening elastic member 184 can be a spring or a torsion spring.

[0086] In some embodiments of the present invention, referring to Figure 2 , Figure 3 As shown, the outward-opening clutch rod 18 comprises a clutch rod body 181 and a clutch rod bracket 182. The clutch rod bracket 182 is rotatably arranged on the lock housing 11. A clutch rod pin 183 is arranged on the clutch rod bracket 182. A clutch rod guide groove 1811 is arranged on the clutch rod body 181. The clutch rod pin 183 is received in the clutch rod guide groove 1811. The length of the clutch rod guide groove 1811 is much larger than the diameter of the clutch rod pin 183, so that the clutch rod body 181 moves relative to the clutch rod bracket 182 along the length direction of the clutch rod guide groove 1811. Under the elastic force of the outward-opening elastic member 184, the clutch rod body 181 is tightly attached to the locking link 19, and the clutch rod bracket 182 can selectively unlock the lock tongue.

[0087] In some embodiments of the present invention, Figure 4 and Figure 5As shown, a first driving end 1411 is formed on the inner-opening clutch rod 141, and the first driving end 1411 is movably arranged on the inner-opening rocker arm 13 to switch between an unlatched position and an upper safety position. The first driving end 1411 is also suitable for cooperating with the unlocking rocker arm 12. When the first driving end 1411 moves to the unlatched position, the inner-opening clutch rod 141 can selectively drive the unlocking rocker arm 12 to rotate under the drive of the inner-opening rocker arm 13.

[0088] Since the inner opening clutch rod 141 is a structure in the door lock assembly 1 for driving the unlocking rocker arm 12 to unlock the lock tongue, the structure of the inner opening clutch rod 141 will affect the use of the door lock assembly 1. A first driving end 1411 is formed on the inner opening clutch rod 141, and the first driving end 1411 is movably disposed on the inner opening rocker arm 13 and is suitable for cooperating with the unlocking rocker arm 12. When the door lock assembly 1 is working, the inner opening rocker arm 13 moves and drives the first driving end 1411 to rotate. The first driving end 1411 can drive the unlocking rocker arm 12 to rotate in certain circumstances so that the unlocking rocker arm 12 can unlock the lock tongue.

[0089] Specifically, the first driving end 1411 can switch between the unsecured position and the secured position on the inner opening rocker arm 13. When the first driving end 1411 moves to the unsecured position, the first driving end 1411 can cooperate with the unlocking rocker arm 12. At this time, the inner opening clutch rod 141 can drive the unlocking rocker arm 12 to rotate under the drive of the inner opening rocker arm 13 to unlock the lock tongue. The specific situation here can be understood as the door lock assembly 1 being in the unsecured state. When the door lock assembly 1 is in the unsecured state, the first driving end 1411 can drive the unlocking rocker arm 12 to rotate to unlock. When the door lock assembly 1 is in the secured state, the first driving end 1411 cannot drive the unlocking rocker arm 12 to rotate and thus cannot unlock. The two different states of cooperation between the first driving end 1411 and the unlocking 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.

[0090] In some embodiments of the utility model, a first matching groove 131 suitable for accommodating the first driving end 1411 is formed on the inner opening rocker arm 13, and the first matching groove 131 extends radially along the pivot axis of the inner opening rocker arm 13. The release position is located on a side close to the pivot axis of the inner opening rocker arm 13, and the upper safety position is located on a side away from the pivot axis of the inner opening rocker arm 13. After the first driving end 1411 moves to the release position, the first driving end 1411 stops against the unlocking rocker arm 12. Figure 4 When the inner opening clutch rod 141 is located at the left end of the first matching groove 131, the door lock assembly 1 is released and the door lock can be normally opened and unlocked inside and outside; when the inner opening clutch rod 141 is located at the right end of the first matching groove 131, the door lock assembly 1 is secured, and a single pull of the inner and outer opening mechanism cannot unlock the door lock.

[0091] Since the first driving end 1411 and the inner opening rocker arm 13 have a matching relationship between the unlocking position and the upper safety position, the structure of the inner opening rocker arm 13 will affect the matching between the first driving end 1411 and the unlocking rocker arm 12. Specifically, a first matching groove 131 suitable for receiving the first driving end 1411 is formed on the inner opening rocker arm 13, and the first matching groove 131 extends radially along the pivot axis of the inner opening rocker arm 13. 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 pivot axis of the inner opening rocker arm 13 is the unsecured position, and the side of the first matching groove 131 away from the pivot axis of the inner opening rocker arm 13 is the upper secure position. When the inner opening rocker arm 13 moves, the first driving end 1411 can reciprocate between the unsecured position and the upper secure position. When the lock tongue needs to be unlocked, the first driving end 1411 can enter the unsecured position and cooperate with the unlocking rocker arm 12. At this time, the movement of the inner opening rocker arm 13 can drive the inner opening clutch rod 141 to move, and the inner opening clutch rod 141 can drive the unlocking rocker arm 12 to rotate to unlock the lock tongue. The structure of the first matching groove 131 realizes the switching of the first driving end 1411 between the unsecured position and the upper secure position, which is convenient for controlling the cooperation between the inner opening clutch rod 141 and the unlocking rocker arm 12.

[0092] In some embodiments of the present invention, the inner crank 143 is provided with a first matching portion, and the first matching portion cooperates with the inner clutch rod 141 to limit the first driving end 1411 from moving from the upper safety position to the released safety position. A first matching portion is provided on the inner opening crank 143, and the first matching portion can cooperate with the inner opening clutch rod 141 to limit the movement of the first driving end 1411 between the upper safety position and the unlocked safety position. Specifically, when the inner opening rocker arm 13 rotates, the inner opening clutch rod 141 moves, and the first driving end 1411 moves in the first matching groove 131. At this time, the inner opening crank 143 does not rotate, and the door lock assembly 1 is in the upper safety state. The first matching portion cooperates with the inner opening clutch rod 141 to limit the first driving end 1411 from moving to the unlocked safety position, and the inner opening clutch rod 141 cannot cooperate with the unlocking rocker arm 12; when the inner opening crank 143 rotates, the door lock assembly 1 is converted into the unlocked safety state, the first driving end 1411 can move to the unlocked safety position and cooperate with the unlocking rocker arm 12, and the inner opening clutch rod 141 can drive the unlocking rocker arm 12 to unlock the lock tongue under the drive of the inner opening rocker arm 13. It can be simply understood that the inner crank 143 can control whether the inner clutch rod 141 can complete the unlocking process. The setting of the inner 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 assembly 1.

[0093] In some embodiments of the present utility model, the door lock assembly 1 further comprises a super lock clutch rod 142, one end of which is rotatably arranged on the super lock device 15, the other end of which is hinged to the inner opening rocker arm 13, and a second driving end 1421 is arranged on the super lock clutch rod 142, and the second driving end 1421 is suitable for driving the inner opening crank 143 to rotate along the second direction to release the movement restriction of the driving end by the first matching part. Because the inner opening crank 143 can selectively restrict the movement of the first driving end 1411. One end of the super lock clutch rod 142 is rotatably arranged in the lock housing 11, and the other end of the super lock clutch rod 142 is hinged with the inner opening rocker arm 13. When the inner opening rocker arm 13 rotates, the super lock clutch rod 142 can rotate under the drive of the inner opening rocker arm 13. The super lock clutch rod 142 is also formed with a second driving end 1421, and the second driving end 1421 can selectively cooperate with the inner opening crank 143 to drive the inner opening crank 143 to move. Specifically, when the inner opening rocker arm 13 rotates, the inner opening clutch rod 141 and the super lock clutch rod 142 simultaneously follow As the inner opening rocker arm 13 moves, when the super lock clutch rod 142 moves to a certain position, the second drive end 1421 can cooperate with the inner opening crank 143. At this time, the super lock clutch rod 142 can drive the inner opening crank 143 to rotate. When the inner opening 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 insurance state to the uninsured state. At this time, the first drive end 1411 can cooperate with the unlocking rocker arm 12 so that the inner opening clutch rod 141 drives the unlocking 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 inner opening crank 143. The setting of the super lock clutch rod 142 makes the rotation of the inner opening crank 143 controllable, thereby realizing the conversion of the door lock assembly 1 between the insurance state and the uninsured state.

[0094] In some embodiments 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 inner crank 143, and a first boss 1412 protruding in the thickness direction is formed on the inner clutch rod 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 inner crank 143, and a second boss protruding in the thickness direction is formed on the super lock clutch rod 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 inner crank 143 to rotate in the second direction.

[0095] Since the inner crank 143 has a corresponding matching relationship with the inner clutch rod 141 and the super lock clutch rod 142, the structure of the inner crank 143 will affect the conversion of the door lock assembly 1 between the safety state and the safety release state. Specifically, the outer periphery of the inner 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 inner clutch rod 141, and a second boss is formed on the super lock clutch rod 142, wherein the first boss 1412 protrudes in the thickness direction of the inner clutch rod 141 and can stop with 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 super lock clutch rod 142 and can stop with 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.

[0096] During operation, the inner opening rocker arm 13 rotates, the inner opening clutch rod 141 and the super lock clutch rod 142 follow the movement of the inner opening rocker arm 13, and the first boss 1412 on the inner opening clutch rod 141 moves along the first radial extension portion 1431 toward the direction close to the inner opening crank 143, and the second boss on the super lock clutch rod 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 super lock clutch rod 142 can drive the inner opening crank 143 to rotate. When the inner opening crank 143 rotates a certain angle, the inner opening rocker arm 13 rotates again to drive the inner opening clutch rod 141, so that the first driving end 1411 can enter the unlatching position and cooperate with the unlocking rocker arm 12. At this time, the inner opening clutch rod 141 can drive the unlocking rocker arm 12 to move to unlock the lock tongue. The structure of the inner opening crank 143 enables the inner opening clutch rod 141 and the super lock clutch rod 142 to cooperate with the corresponding structures on the inner opening crank 143 respectively to realize the control of the unlocking process, ensuring the normal use of the door lock assembly 1, so that when the inner opening rocker arm 13 is rotated for the first time, the inner opening crank 143 is rotated to the unlatched state, and after the inner opening rocker arm 13 is rotated again, the inner opening rocker arm 13 can drive the inner opening clutch rod 141 to drive the unlocking rocker arm 12 to realize unlocking.

[0097] In some embodiments of the utility model, a third driving end 1422 is formed on the super lock clutch rod 142, and a third matching groove 132 suitable for accommodating the third driving end 1422 is formed on the inner crank 143. The length of the third matching groove 132 is much larger than the diameter of the third driving end 1422, so that the third driving end 1422 can move along the groove wall of the third matching groove 132, thereby preventing the mechanism from getting stuck when the super lock clutch rod 142 rotates relative to the inner crank 143.

[0098] In some embodiments of the present invention, the super lock device 15 is adapted to drive the super lock clutch rod 142 to rotate, so as to drive the second boss to separate from the second radial extension portion 1432 and / or the super lock device 15 to rotate to abut against the inner opening crank 143 to limit the rotation of the inner opening crank 143. Since the rotation of the inner opening crank 143 will affect the switching between the insurance state and the release state on the door lock assembly 1, the door lock assembly 1 needs to be constructed with a structure capable of limiting the movement of the inner opening crank 143 to avoid the inner opening crank 143 having an excessive movement range and affecting the use of the door lock assembly 1. Specifically, the door lock assembly 1 is also provided with a super lock device 15, which is rotatably arranged on the lock housing 11, and one end of the super lock clutch rod 142 is rotatably arranged on the super lock device 15. When the inner opening rocker arm 13 rotates, the super lock clutch rod 142 can be driven by the inner opening rocker arm 13 to rotate with the connection position between the super lock clutch rod 142 and the super lock device 15 as the axis. At the same time, when the super lock device 15 itself rotates, it can also drive the super lock clutch rod 142 to move. For example, when the super lock device 15 rotates toward the inner opening crank 143, the super lock clutch rod 142 is driven by the super lock device 15 to move toward the rotation axis close to the inner opening rocker arm 13. It is worth noting that the rotation of the super lock device 15 toward the inner opening crank 143 can be understood as Figure 4 The super lock device 15 shown in the figure rotates counterclockwise. When the super lock device 15 rotates toward the inner crank 143 by a certain angle, the super lock clutch rod 142 is disengaged from the inner crank 143 under the drive of the super lock device 15, and the second boss is located radially outside the second radial extension 1432, so that the second boss cannot stop with the second radial extension 1432. At this time, the rotation of the super lock clutch rod 142 will not drive the inner crank 143 to rotate, and at least part of the edge of the super lock device 15 can stop with at least part of the edge of the inner crank 143, so that the inner crank 143 cannot rotate, that is, the inner crank 143 cannot be converted from the insurance state to the release state, and the door lock is always in the locked state. The setting of the super lock device 15 can keep the door lock in a locked state under specific circumstances, avoid misunderstanding of the lock operation, and improve the safety of the door lock assembly 1.

[0099] In some embodiments of the utility model, a fourth driving end 1423 is formed on the super lock clutch rod 142, and a guide groove 1511 suitable for accommodating the fourth driving end 1423 is formed on the worm wheel 151, and the length of the guide groove 1511 is much larger than the diameter of the fourth driving end 1423, so that the fourth driving end 1423 can move along the groove wall of the guide groove 1511, thereby preventing the mechanism from getting stuck when the super lock clutch rod 142 rotates relative to the worm wheel 151.

[0100] In some embodiments, Figure 8 and Fig. 9As shown, an unlocking protrusion 121 is formed on the outer periphery of the unlocking rocker arm 12. When the inner opening clutch rod 141 is in the upper safety position, the distance from the first driving end 1411 to the pivot axis of the unlocking rocker arm 12 is greater than the distance from the unlocking protrusion 121 to the pivot axis of the unlocking rocker arm 12. When the inner opening clutch rod 141 is in the unsafe position, the first driving end 1411 abuts against one circumferential side of the unlocking protrusion 121. In this way, the occupied space can be reduced as much as possible, and the action switching of the inner opening clutch rod 141 is smoother.

[0101] In some embodiments of the present invention, the door lock assembly 1 further comprises a child lock crank 16, which is disposed on the lock housing 11, and one end of the inner clutch rod 141 is hinged to the child lock crank 16, and the child lock crank 16 can selectively move to drive the inner clutch rod 141 to move, so as to keep the first driving end 1411 in the upper safety position. In the embodiment, the end of the inner clutch rod 141 is rotatably connected to the child lock crank 16. The child lock crank 16 is rotatably disposed on the lock housing 11, and the rotation of the child lock crank 16 will affect the matching relationship between the inner clutch rod 141 and the unlocking rocker arm 12. Figure 4 As shown, when the child lock crank 16 rotates counterclockwise, the inner opening clutch rod 141 will move in a direction away from the unlocking rocker arm 12 under the drive of the child lock crank 16. At this time, the first driving end 1411 will always be in the upper safety position. No matter how the inner opening rocker arm 13 moves, the inner opening clutch rod 141 cannot drive the unlocking rocker arm 12 to unlock the lock tongue. It can also be understood that the door lock assembly 1 is always in the upper safety state. The setting of the child lock crank 16 can make the door lock assembly 1 have a safety function, avoid the door lock from being opened by mistake, and improve the safety of the door lock assembly 1.

[0102] In some embodiments of the present utility model, the child lock crank 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 received in the second matching groove 1611 is formed on the inner clutch rod 141. Since one end of the inner clutch rod 141 is connected to the child lock crank 16, the structure of the child lock crank 16 will affect the movement of the inner clutch rod 141. Specifically, the child lock crank 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 inner clutch rod 141. When assembled, the third boss 1413 is received in the second matching groove 1611 and can slide in the second matching groove 1611. The second matching groove 1611 is provided to facilitate the relative movement between the inner opening clutch rod 141 and the child lock crank 16, so that the child lock crank 16 can drive the inner opening clutch rod 141 to move together without affecting the movement of the inner opening clutch rod 141 itself, so as to ensure the freedom and range of motion of the inner opening clutch rod 141.

[0103] In some embodiments of the utility model, the child lock crank 16 further includes a limiting elastic member 162, which is disposed on the support plate 161 and is suitable for keeping the inner opening clutch rod 141 against the first matching portion. During assembly, the child lock crank 16 is further provided with a limiting elastic member 162 on the support plate 161, and the limiting elastic member 162 can be against the third boss 1413 to drive the inner opening clutch rod 141 to maintain a fitting relationship with the first matching portion. When the inner opening crank 143 rotates, the structure of the limiting elastic member 162 can make the inner opening clutch rod 141 also fit with the first matching portion during movement, so as to facilitate the inner opening crank 143 to control the inner opening clutch rod 141. When the child lock crank 16 rotates, due to the matching relationship between the second matching groove 1611 and the third boss 1413 , the limiting elastic member 162 does not affect the separation of the inner opening clutch rod 141 and the inner opening crank 143 , and can keep the inner opening clutch rod 141 stable.

[0104] In some embodiments of the present invention, the pivot axis of the support plate 161 is coaxially arranged with the pivot axis of the worm gear 151. In other words, the child lock crank 16 and the worm gear 151 share a common axle pin, which is installed on the lock housing 11 through the pin axis. They can rotate independently with the pin axis as the pivot axis, which can further improve the structural compactness of the door lock assembly 1.

[0105] In some embodiments of the present invention, 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 pivot axis of the unlocking rocker arm 12. 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 unlocking rocker arm 12 and the inner opening rocker arm 13. The coaxial arrangement of the central control wheel 17 with the unlocking rocker arm 12 and the inner opening rocker arm 13 can improve the compactness of the structure of the door lock assembly 1 and reduce the occupied space.

[0106] In some embodiments, the door lock assembly 1 may also be provided with an inner opening pull wire 101, which may be connected to the inner opening rocker arm 13. By driving the inner opening rocker arm 13 to move through the inner opening pull wire 101, the force driving the inner opening rocker arm 13 to move can be reduced, making the unlocking process of the door lock assembly 1 more labor-saving.

[0107] like Figure 2-Figure 4 As shown, a schematic diagram of the installation of a door lock assembly 1 of a specific example of the utility model is shown, in which a worm gear 151 is installed on the lock housing 11 through an axle pin, and the worm gear 151 can rotate relative to the lock housing 11 around the axle pin, and is provided with a driving member 153 and a worm 152 to drive the worm gear 151 to rotate.

[0108] Figure 2In the embodiment, the right end of the super lock clutch rod 142 is hingedly fixed on the worm wheel 151, and the super lock clutch rod 142 can rotate around the hinge fixing point. Specifically, a guide groove 1511 is provided on the worm wheel 151, and the fourth driving end 1423 at the right end of the super lock clutch rod 142 cooperates with the guide groove 1511 on the worm wheel 151, so that the right end of the super lock clutch rod 142 can slide in the guide groove 1511 on the worm wheel 151. The left end of the super lock clutch rod 142 is provided with a third driving end 1422, and the third driving end 1422 cooperates with the third matching groove 132 on the inner opening rocker arm 13, and the super lock clutch rod 142 can slide left and right along the third matching groove 132. The support plate 161 of the child lock crank 16 is coaxially pin-mounted with the worm gear 151. A second matching groove 1611 is formed on the support plate 161 of the child lock crank 16. The third boss 1413 at the right end of the inner clutch rod 141 matches with the second matching groove 1611, and the inner clutch rod 141 is given a force to the left along the second matching groove 1611 through the limit elastic member 162. The inner clutch rod 141 can slide left and right along the second matching groove 1611. The first driving end 1411 at the left end of the inner clutch rod 141 matches with the first matching groove 131 on the inner rocker arm 13. The inner clutch rod 141 can also slide left and right along the first matching groove 131. The inner crank 143 rotates around another axle pin, the locking link 19 is hinged to the upper end of the inner crank 143, and the outer clutch rod 18 is tightly attached to the locking link 19 under the elastic force of the outer elastic member 184. Figure 4 The figure shows that the outer opening clutch rod 141 is in the released position. When the outer opening clutch rod 141 rotates, it will move the unlocking rocker arm 12 to realize the unlocking process.

[0109] Figure 3 The back side shows the installation diagram of the door lock assembly 1 of the present invention, wherein the inner crank 143 is connected to the lock housing 11 via another pin shaft, and can be rotated by using the other pin shaft as a pivot axis. A first radial extension portion 1431 is provided below the inner crank 143, and the first radial extension portion 1431 interacts with the first boss 1412 on the back side of the inner clutch rod 141, that is, under the action of the limiting elastic member 162, the first boss 1412 on the back side of the inner clutch rod 141 always has a force to press against the first radial extension portion 1431 of the inner crank 143.

[0110] Reference Figure 4 When the inner crank 143 rotates counterclockwise, Figure 6 It can be seen that the first radial extension portion 1431 below the inner crank 143 will move the first boss 1412 of the inner clutch rod 141, so that the inner clutch rod 141 is moved to Figure 4 The first driving end 1411 moves along the first matching groove 131 on the lower side of the inner opening rocker arm 13. Figure 4At this time, the position of the first driving end 1411 of the inner opening clutch rod 141 is out of the interference with the unlocking rocker arm 12 in terms of travel. Therefore, when the inner opening cable 101 is pulled, the first driving end 1411 will not drive the unlocking rocker arm 12 to rotate, that is, the insurance state. Figure 4 The counterclockwise rotation will drive the super lock clutch rod 142 to rotate clockwise around the axis point on the worm gear 151. Figure 4 The second driving end 1421 at the lower end of the super lock clutch rod 142 drives the second radial extension portion 1432 of the inner crank 143 to rotate counterclockwise, and the inner clutch rod 141 returns to the Figure 4 The unlocking action can be completed by pulling the inner opening pull wire 101 again, thus realizing the inner opening double-pull unlocking process of the door lock assembly 1.

[0111] When the inner opening clutch rod 141 is in the release position, the first driving end 1411 of the inner opening clutch rod 141 is located at Figure 4 As shown in the left side of the first matching groove 131, the inner opening pull wire 101 is pulled at this time, the inner opening rocker arm 13 rotates counterclockwise, and drives the first driving end 1411 of the inner opening clutch rod 141 to move upward, and the first driving end 1411 contacts the unlocking rocker arm 12, so that the unlocking rocker arm 12 rotates counterclockwise around the axis, and the unlocking action can be realized.

[0112] When the child lock is locked, the crank 16 of the child lock rotates counterclockwise. At this time, the third boss 1413 on the inner opening clutch rod 141 moves to the leftmost position along the second matching groove 1611, and restricts the inner opening clutch rod 141 from moving to the left. At this time, the inner opening clutch rod 141 is in the upper safety position, and the inner pull unlocking cannot be opened. Even if the inner opening pull wire 101 is pulled for the first time during the double pulling process, which drives the inner opening crank 143 to rotate clockwise to the unsafety position, the inner opening clutch rod 141 cannot continue to move to the left under the action of the limiting elastic member 162, thus realizing the function of the inner pull unlocking failure required by the child lock. In other words, after the crank 16 of the child lock rotates counterclockwise, it restricts the inner opening clutch rod 141 from returning to the unsafety position, and makes the inner opening clutch rod 141 in the upper safety position.

[0113] When the super lock button is pressed, the domain controller sends a signal, the driving member 153 works, the driving member 153 drives the worm 152 to rotate, the worm wheel 151 is driven by the worm 152 to rotate counterclockwise, and the edge of the worm wheel 151 pushes the inner opening crank 143 to the left, which will force the inner opening crank 143 to rotate counterclockwise to push the inner opening clutch rod 141 to move right to the upper safety position, that is, the inner pull unlocking fails. When the worm wheel 151 rotates counterclockwise, the right end of the super lock clutch rod 142 is pushed to move to the left through the guide groove 1511, and the left end of the super lock clutch rod 142 slides to the left in the third matching groove 132 of the inner opening rocker arm 13. At this time, the inner opening pull wire 101 is pulled. Since the inner opening clutch rod 141 slides to the right, when the inner opening pull wire 101 drives the inner opening rocker arm 13 to rotate counterclockwise, the inner opening clutch rod 141 and the unlocking rocker arm 12 do not come into contact. The inner opening pull wire 101 is pulled in vain, and can neither drive the central control to unlock nor drive the door lock to unlock.

[0114] At the same time, when the inner opening crank 143 rotates counterclockwise, the locking link 19 hinged at the upper end of the inner opening crank 143 is also pushed to the left, so that the outer opening clutch rod 18 close to the locking link 19 will be pushed, so that the central control is locked, and the outer opening clutch rod 18 cannot turn the unlocking rocker arm 12 when rotating around the axis, that is, the outer pull unlocking fails, and the vehicle cannot be opened from the outside. In addition, when the super lock is locked, because the worm gear 151 supports the upper end of the inner opening crank 143, the inner opening crank 143 cannot rotate clockwise to the inner opening clutch rod 141 to release the insurance position, so when the door lock assembly 1 enters the super lock state, the super lock function will cover the child lock function, the door lock cannot be released, the entire vehicle central control will be locked, the double pull will fail, the door lock inner opening and outer opening will fail, and the door cannot be opened from outside or inside the vehicle, thereby improving safety.

[0115] After pressing the super lock unlocking button, the domain controller sends a signal, the driving part 153 works, and the worm gear 151 rotates clockwise through the worm 152. The edge of the worm gear 151 releases the restriction on the inner opening crank 143, and the central control unlocking function returns to normal, so that the normal unlocking and locking of the central control can be achieved. At the same time, under the action of the spring, the right end of the super lock clutch rod 142 moves to the right along with the worm gear 151, and the left end of the super lock clutch rod 142 moves to the right in the third matching groove 132 of the inner opening rocker arm 13. At this time, the inner opening pull wire 101 is pulled, and the inner opening rocker arm 13 rotates counterclockwise to drive the super lock clutch rod 142 to rotate clockwise. At this time, the second driving end 1421 of the super lock clutch rod 142 pushes the second radial extension part 1432 of the inner opening crank 143 to drive the inner opening crank 143 to rotate clockwise, and the inner opening clutch rod 141 moves to the left to the unfastened position. At the same time, the inner opening crank 143 rotates clockwise while driving the locking connecting rod 19 to move to the right, thereby realizing the central control unlocking.

[0116] According to the door lock assembly 1 of the embodiment of the utility model, when the worm gear 151 is in the working position, the inner opening pull wire and the outer opening clutch rod 18 can be shielded from unlocking the central control function, so that both the inner opening and the outer opening cannot be unlocked, thereby realizing the super lock and child lock functions at the same time. The door lock assembly 1 of the embodiment of the utility model has a small number of parts, a simple structure, high reliability, and good application prospects. At the same time, replacing the electronic child lock with a mechanical child lock can play a cost reduction role. Among them, the super lock function covers the child lock function. When the door lock enters the super lock locked state, the car door cannot be opened from inside or outside the car, and the insurance cannot be released. When the super lock is not locked, the mechanical child lock can work independently. In the child lock locked state, the inner opening pull wire of the car door cannot drive the door lock to unlock through the transmission mechanism, and the door lock function returns to normal after the child lock is unlocked. The application of this structure enables the electrolytic electric suction lock to realize the super lock function, which is conducive to improving the insurance rating of export models, reducing premiums, and contributing to the expansion of vehicle model export projects.

[0117] The vehicle 10 according to the present invention is briefly described below.

[0118] Reference Fig.10 As shown, the vehicle 10 according to the utility model includes the door lock assembly 1 in the above embodiment. Since the vehicle 10 according to the utility model is provided with the door lock assembly 1 in the above embodiment, when the door lock assembly 1 is assembled with the vehicle door, the door lock assembly 1 has a simple structure and occupies a small space, which can save the layout space in the vehicle door and is conducive to the layout of other structures. At the same time, the door lock assembly 1 has few transmission parts and a simple structure, which can reduce the cost of replacing and repairing the vehicle door lock in the later stage. In addition, the door lock assembly 1 can drive the inner opening crank 143 to rotate to drive the inner opening clutch rod 141 to move to the upper safety position by providing a super lock device 15. At this time, even if the inner opening rocker arm 13 is rotated, the inner opening clutch rod 141 cannot move to the release safety position, thereby shielding the release safety function, which is conducive to improving the safety of the door lock assembly 1.
