The specific embodiment
as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model is a kind of multi-functional unlatching of spring revolving door type mechanism of automobile door lock, comprise the first connecting axle A, the second connecting axle B and the 3rd connecting axle C, be rotatably connected to safety arm 1 on the first connecting axle A, be rotatably connected to control arm 2 and release arm 3 on the second connecting axle B, be rotatably connected to lock pawl 4 on the 3rd connecting axle C, lower-left one end of release arm 3 contacts cooperation with the projection 5 on lock pawl 4, the left upper end of release arm 3 is provided with the 4th connecting axle D, be rotatably connected to the clutch arm 7 that coordinates with safety arm 1 on the 4th connecting axle D, release arm 3 is provided with slot to make way 8, control arm 2 is provided with pin 6 or the boss structure that is through in slot to make way 8, release arm 3 is provided with the clutch arm torsion spring 9 that coordinates with clutch arm 7.
The left end of clutch arm 7 upper edges and middle part arrange respectively a solution locking that coordinates with safety arm 1 and drive boss structure 10 and open ice driving boss structure 11, the drive surface of separating the top and safety arm 1 of locking driving boss structure 10 coordinates, separate locking drive boss structure 10 below be used for the stumbling spring leg of clutch arm torsion spring 9, the right-hand member of clutch arm 7 lower edges is provided with the ledge structure 12 that matches with pin 6 on control arm 2.Clutch arm 7 back sides up and down are along being respectively equipped with on convex platform 13 and lower convex platform 14 and release arm 3 on edge and slot to make way 8 along coordinating, the position-limiting action of realization to clutch arm 7.Safety arm 1 is provided with and contacts the nonmetal cover 13 that coordinates with clutch arm 7, can effectively improve the noise reduction of mechanism, anticorrosion and antiwear property.Opening ice drives boss structure 11 in order to guarantee in the situation that because the reasons such as freezing or 9 inefficacy of clutch arm torsion spring cause effectively return of clutch arm 7, and safety arm 1 can make the reliable return of clutch arm 7 by the promotion driving boss structure 11 that opens ice.
when work is used, after closing of the door, the automobile door lock locking device is in closure state, safety arm 1 is in the unlocked position, as shown in Figure 1, contact with the upper edge of release arm 3 along convex platform 13 on clutch arm 7, clutch arm 7 coordinates formation transmission guide groove with release arm 3, in pulling door lock, in outer operating mechanism drives, when outer unlatching arm is opened, the control arm 2 that drives on the second connecting axle B pivots, the pin 6 that is riveted on control arm 2 drives release arm 3 rotations by the transmission guide groove, release arm 3 drives lock pawl 4 by the projection 5 on lock pawl 4, thereby in realizing, outer unlatching function.when being rotated clockwise to the lock position with manual or motor-operating mechanism promotion safety arm 1, as shown in Figure 2, safety arm 1 drives clutch arm 7 and is rotated counterclockwise, the clutch arm coordinates spacing along lower convex platform 14 with the upper edge of the slot to make way 8 of release arm 37 times, the transmission guide barrel construction disappears, pull in door lock, in outer operating mechanism drives, when outer unlatching arm is opened, control arm 2 around the second connecting axle B rotation drives the below that pin 6 is threaded to clutch arm 7, as shown in Figure 3, pin 6 on control arm 2 can't drive release arm 3 motions, can not drive lock pawl 4, in, the external-open disabler, realize latch functions.when safety arm 1 is in the lock position, if pull in door lock, in outer operating mechanism drives, outer unlatching arm is to maximum position and maintenance, then manual or electric operating safety arm carries out unlocking operation, as shown in Figure 4, but safety arm 1 freely-movable is to unlocked position, but the motion of clutch arm 7 is stopped by the pin 6 of riveted joint on control arm 2, discharge in door lock this moment, outer operating mechanism, control arm 2 backwards rotation, 6 pairs of clutch arms 7 of pin stop disappearance, clutch arm 7 clockwise rotates under the effect of clutch arm torsion spring 9, contact with the upper edge of release arm 3 along convex platform 13 on clutch arm 7, the transmission guide groove is rebuild, be returned to unlocked position, state as shown in Figure 1, again pull in door lock, outer operating mechanism, door lock is realized nervous open function.Said structure pulls interior when effectively having avoided door lock to be in lockup state or outdoor handle will cause the release action to be lost efficacy.
The present embodiment is not that shape of the present utility model, material, structure etc. are done any pro forma restriction; every foundation technical spirit of the present utility model all belongs to the protection domain of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment does.
