[0026] The technical solution of the present invention will be explained in more detail below with reference to the accompanying drawings and specific embodiments.
[0027] As in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. Figure 16 shows an embodiment of a super-lock for sliding doors in vehicles, wherein the super-lock for sliding doors in vehicles comprises a coupling mechanism, a release arrangement, a locking mechanism and an actuating mechanism, wherein the coupling mechanism comprises an inwardly open connecting rod 1, a positioning rod 2 and a locking pin 3, wherein the inwardly open connecting rod 1 is pivotally connected to the positioning rod 2, wherein a locking groove 201 is formed at one end of the positioning rod 2, wherein the locking groove 201 comprises a first longitudinal groove 2011 and a second longitudinal groove 2012 which are interconnected, wherein a longitudinal direction of the first longitudinal groove 2011 and a longitudinal direction of the second longitudinal groove 2012 are arranged at an angle to each other.wherein a groove 101 is formed at one end of the inwardly open connecting rod 1, wherein the locking pin 3 is simultaneously arranged in the groove 101 and the locking groove 201, wherein the locking mechanism is used to lock a rear door to a body, wherein the unlocking arrangement is connected between the other end of the inwardly open connecting rod 1 and the locking mechanism and can trigger the unlocking of the locking mechanism, wherein the actuating mechanism 5 is used to drive the locking pin 3 in such a way thatThe locking pin is designed to slide within the locking groove 201 and has an open position for unlocking the locking mechanism and a closed position for locking the locking mechanism. In this way, the actuating mechanism 5 can move the locking pin 3 into the closed position. As a result, the locking pin 3 only slides transversely to the second longitudinal groove 2012 and cannot rotate the inwardly open connecting rod 1. This means that the release mechanism cannot be pulled to release the locking mechanism. Both the inside and outside door opening functions are disabled, thus providing the super-security function. This ensures the continued security of the door lock.
[0028] Optional includes, as in Fig. 11 and Fig. Figure 12 shows the coupling mechanism further comprising a first connecting rod 4, wherein the actuating mechanism 5 is drive-connected to the first connecting rod 4 and can rotate the first connecting rod 4 so that the first connecting rod 4 drives the locking pin 3 such that the locking pin is provided slidingly in the locking groove 201, and the actuating mechanism 5 comprises a drive element 51, a worm gear 52 and a worm 53, wherein the drive element 51 is drive-connected to the worm 53 and can rotate the worm 53, the worm gear 52 being in engagement with the worm 53, wherein the first connecting rod 4 is provided with a gear structure, the worm gear 52 being in engagement with the gear structure. In particular, the drive element 51 is an electric motor. In this way, the drive element 51 starts up and drives the worm 53 to rotate the worm gear 52.This in turn causes the worm gear 52 to rotate the first connecting rod 4 counterclockwise via the gear structure, causing the first connecting rod 4 to rotate and push the locking pin 3 to a connection point between the first longitudinal groove 2011 and the second longitudinal groove 2012, so that the locking pin 3 is in the closed position in which the locking mechanism is locked.
[0029] In this embodiment, to ensure the stability and reliability of the locking pin 3 in the open or closed position, the coupling mechanism further comprises an elastic element 6, wherein the elastic element 6 is configured to limit the rotation angle of the first connecting rod 4. In particular, the elastic element 6 is a torsion spring.
[0030] In particular, as in Fig. 13 and Fig. As shown in Figure 14, this embodiment provides, for example, the following technical solution: the coupling mechanism further comprises a second connecting rod 7, a pull rod 8 and an inwardly open handle 9, wherein the second connecting rod 7, the inwardly open connecting rod 1 and the positioning rod 2 are pivotally connected to one another, wherein a sliding groove 701 is formed in the second connecting rod 7, wherein one end of the pull rod 8 is provided to slide in the sliding groove 701, wherein another end of the pull rod 8 is connected to the inwardly open handle 9, wherein a fastening pin 10 is provided at another end of the positioning rod 2, wherein the fastening pin 10 can bear against an end of the second connecting rod 7 facing the inwardly open handle 9.In this way, when the locking pin 3 is in the closed position, in which the locking mechanism is locked, and a force is applied to the inwardly open handle 9 to move the pull rod 8 horizontally to the right, the pull rod 8 rotates the second connecting rod 7 clockwise. The second connecting rod 7 rests against the fixing pin 10, causing the fixing pin 10 to rotate the positioning rod 2 clockwise. At this point, the locking pin 3 only engages transversely to the second longitudinal groove 2012, thus preventing the locking pin 3 from rotating the inwardly open connecting rod 1 clockwise. This means the release mechanism cannot be pulled to release the locking mechanism, and the inward door opening function is disabled.
[0031] Optional includes, as in Fig. 15 and Fig. As shown in Figure 16, the coupling mechanism further comprises an outwardly open connecting rod 11, wherein the outwardly open connecting rod 11 is actuated to the positioning rod 2 and can rotate the positioning rod 2. In this way, when the locking pin 3 is in the closed position in which the locking mechanism is locked, and a horizontal force acting to the left is applied to the outwardly open connecting rod 11 to rotate the positioning rod 2 clockwise, the locking pin 3 only engages in a sliding manner transverse to the second longitudinal groove 2012, thus preventing the locking pin 3 from rotating the inwardly open connecting rod 11 clockwise. This means that the release mechanism cannot be pulled to release the locking mechanism, and the function of the external door opening is disabled.
[0032] Furthermore, a connecting end for an external release pull cord and a connecting end for an electric release pull cord are provided on the outwardly open connecting rod 11.
[0033] It should be noted that, as in Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. As shown in Figure 10, when unlocking, the drive element 51 is activated and the worm 53 rotates the worm wheel 52. This, in turn, causes the worm wheel 52 to rotate the first connecting rod 4 clockwise via the gear structure, causing the locking pin 3 to engage against a bottom wall of the first longitudinal groove 2011, and the elastic element 6 holds the first connecting rod 4 in this position. At this point, a force exerted on the inwardly open handle 9 causes the pull rod 8 to move horizontally to the right, thereby rotating the second connecting rod 7 clockwise.The second connecting rod 7 rests against the fixing pin 10, causing the fixing pin 10 to rotate the positioning rod 2 clockwise. This, in turn, causes the locking pin 3 to rotate the inwardly open connecting rod 1 clockwise, thus pulling the release mechanism and triggering the unlocking of the locking mechanism to open the door. If a horizontal force acting to the left is applied to the outwardly open connecting rod 11 to rotate the positioning rod 2 clockwise, the locking pin 3 pushes the inwardly open connecting rod 1 clockwise, pulling the release mechanism and triggering the unlocking of the locking mechanism to open the door.
[0034] In this embodiment, the unlocking arrangement comprises a first unlocking pull cord, a second unlocking pull cord, and a third unlocking pull cord. The locking mechanism includes a front lock for the rear door, a rear lock for the rear door, and a limit switch. One end of the first unlocking pull cord is connected to the inwardly open connecting rod 1, and the other end of the first unlocking pull cord 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 pull cord is connected to the inwardly open connecting rod 1, and the other end of the second unlocking pull cord 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 release cord is connected to the coupling mechanism, the other end of the third release cord is connected to the boundary lock and can trigger the release of the boundary lock.
[0035] In this embodiment, as in Fig. As shown in Figure 2, the first connecting end 12, the second connecting end 13 and the third connecting end 14 are used to be connected to the first release pull cord, the second release pull cord and the third release pull cord respectively.
[0036] Naturally, the above embodiments of the present invention are intended only to illustrate the invention and do not constitute a limitation of the embodiments of the present invention. Based on the above description, further variations or modifications in various forms are possible for those skilled in the art. It is neither necessary nor possible to list all embodiments herein.
