[0049] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0050] As Figures 1 to 16As shown, this embodiment provides a super lock for a sliding door of an automobile, and the super lock for the sliding door of an automobile comprises: a linkage mechanism, an unlocking assembly, a locking mechanism and an actuator 5, the linkage mechanism comprises an inner opening link 1, a positioning link 2 and a locking pin 3, the inner opening link 1 is hinged to the positioning link 2, one end of the positioning link 2 is provided with a locking groove 201, the locking groove 201 comprises a first long groove 2011 and a second long groove 2012 which are connected, and the length direction of the first long groove 2011 is connected to the second long groove 2012. 12 is set at an angle in the length direction, a slot hole 101 is opened at one end of the inner opening link 1, and the locking pin 3 is placed in the slot hole 101 and the locking slot 201 at the same time. The locking mechanism is used to lock the rear door on the vehicle body, and the unlocking component is connected between the other end of the inner opening link 1 and the locking mechanism, and can trigger the locking mechanism to unlock. The actuator 5 is used to drive the locking pin 3 to slide in the locking slot 201 and has an open position that can unlock the locking mechanism and a closed position that locks the locking mechanism. In this way, the actuator 5 can drive the locking pin 3 to slide to the closed position, so that the locking pin 3 only slides with the second long slot 2012 horizontally, and cannot push the inner opening link 1 to rotate, that is, it is impossible to pull the unlocking component to trigger the locking mechanism to unlock, and the inner and outer releases to open the door are both invalid, with a super lock function, further ensuring the safety of the door lock.

[0051] Optionally, see Figure 11 and Figure 12 As shown, the linkage mechanism also includes a first connecting rod 4, an actuator 5 is connected to the first connecting rod 4 by transmission, and can drive the first connecting rod 4 to rotate so that the first connecting rod 4 drives the locking pin 3 to slide in the locking groove 201, and the actuator 5 includes a driving member 51, a worm wheel 52 and a worm 53, the driving member 51 is connected to the worm 53 by transmission, and can drive the worm 53 to rotate, the worm wheel 52 is meshedly connected to the worm 53, and the first connecting rod 4 is provided with a gear structure, and the worm wheel 52 is meshedly connected to the gear structure. Specifically, the driving member 51 is a motor. In this way, the driving member 51 starts and drives the worm 53 to drive the worm wheel 52 to rotate, and then the worm wheel 52 drives the first connecting rod 4 to rotate counterclockwise through the gear structure, so that the first connecting rod 4 rotates and pushes the locking pin 3 to the connection between the first long groove 2011 and the second long groove 2012, so that the locking pin 3 is located in the closed position of locking the locking mechanism.

[0052] In this embodiment, in order to ensure the stability and reliability of the locking pin 3 when it is maintained in the open position or the closed position, the linkage mechanism further includes an elastic member 6, which is configured to limit the rotation angle of the first connecting rod 4. Specifically, the elastic member 6 is a torsion spring.

[0053] For details, please refer to Figure 13 and Figure 14As shown, the following technical solution is exemplarily given in this embodiment: The linkage mechanism further includes a second link 7, a pull rod 8 and an inboard opening handle 9. The second link 7, the inboard opening link 1 and the positioning link 2 are hinged. A chute 701 is provided on the second link 7. One end of the pull rod 8 is slidably disposed in the chute 701, and the other end of the pull rod 8 is connected to the inboard opening handle 9. A fixing pin 10 is provided at the other end of the positioning link 2, and the fixing pin 10 can abut against one end of the second link 7 close to the inboard opening handle 9. With such a setting, when the locking pin 3 is in the closed position where the locking mechanism is locked, a force is applied to the inboard opening handle 9 to drive the pull rod 8 to move horizontally to the right. The pull rod 8 will drive the second link 7 to rotate clockwise. The second link 7 abuts against the fixing pin 10 and causes the fixing pin 10 to drive the positioning link 2 to rotate clockwise. At this time, the locking pin 3 is only in transverse sliding fit with the second long slot 2012, so that the locking pin 3 cannot push the inboard opening link 1 to rotate clockwise, that is, it cannot pull the unlocking assembly to trigger the unlocking of the locking mechanism, and the inboard release opening fails.

[0054] Optionally, please refer to Figure 15 and Figure 16 As shown, the linkage mechanism further includes an outboard opening link 11. The outboard opening link 11 is drivingly connected to the positioning link 2 and can drive the positioning link 2 to rotate. With such a setting, when the locking pin 3 is in the closed position where the locking mechanism is locked, a horizontally leftward force is applied to the outboard opening link 11 to drive the positioning link 2 to rotate clockwise. At this time, the locking pin 3 is only in transverse sliding fit with the second long slot 2012, so that the locking pin 3 cannot push the inboard opening link 1 to rotate clockwise, that is, it cannot pull the unlocking assembly to trigger the unlocking of the locking mechanism, and the outboard release opening fails.

[0055] Further, an outboard opening cable connection end and an electric unlocking cable connection end are provided on the outboard opening link 11.

[0056] It should be noted that, please refer to Figures 5 to 10 As shown, when unlocking, the driving member 51 is activated and drives the worm 53 to drive the worm wheel 52 to rotate. Further, the worm wheel 52 drives the first link 4 to rotate clockwise through a gear structure, and the locking pin 3 is positioned at the bottom wall of the first long slot 2011, and the first link 4 is restricted in this state by the elastic member 6. At this time, a force is applied to the inboard opening handle 9 to drive the pull rod 8 to move horizontally to the right. The pull rod 8 will drive the second link 7 to rotate clockwise. The second link 7 abuts against the fixing pin 10 and causes the fixing pin 10 to drive the positioning link 2 to rotate clockwise, and further drives the locking pin 3 to push the inboard opening link 1 to rotate clockwise, pulling the unlocking assembly to trigger the unlocking of the locking mechanism to open the door; a horizontally leftward force is applied to the outboard opening link 11 to drive the positioning link 2 to rotate clockwise. At this time, the locking pin 3 pushes the inboard opening link 1 to rotate clockwise, pulling the unlocking assembly to trigger the unlocking of the locking mechanism to open the door.

[0057] In this embodiment, the unlocking assembly includes a first unlocking cable, a second unlocking cable and a third unlocking cable, and the locking mechanism includes a front lock of the rear door, a rear lock of the rear door and a limit lock. One end of the first unlocking cable is connected to the inner opening link 1, and the other end of the first unlocking cable is connected to the front lock of the rear door and can trigger the unlocking of the front lock of the rear door. One end of the second unlocking cable is connected to the inner opening link 1, and the other end of the second unlocking cable is connected to the rear lock of the rear door and can trigger the unlocking of the rear lock of the rear door. One end of the third unlocking cable is connected to the linkage mechanism, and the other end of the third unlocking cable is connected to the limit lock and can trigger the unlocking of the limit lock.

[0058] In this embodiment, please refer to Figure 2 As shown, the first connection end 12, the second connection end 13 and the third connection end 14 are respectively used to correspondingly connect the first unlocking cable, the second unlocking cable and the third unlocking cable.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
