The groundwork state of door lock of the present invention comprises:
1, snap close snaps in Door lock interlocking: the latch openings of the corresponding door lock of snap close snaps in, first contact the intrinsic slide block of lock body, snap close pressing slide block guiding are towards snap close buffer stopper, snap close compresses in cam shedding a side and makes that cam is stressed to be rotated around cam center axle, the gate stop inserts that the rotation of cam center axle pushes against gate stop makes gate stop rotate around gate stop locating shaft, cam is stressed rotate to an angle after, when gate stop is subject to gate stop return spring restoring force to act on cam shedding one side cam embedding mouth to rotate corresponding gate stop inserts, gate stop inserts resets and supports into cam embedding mouth, cam shedding rotates to an angle and forms a closed space with latch openings, snap close correspondence lock onto and in closed space, realizes snap close one-level locking Door lock, wherein cam shedding is fixedly to push against realization by cam embedding mouth and gate stop inserts, its closed space towards another side of cam shedding of opening direction without pushing against not stationary state, at snap close, continue to do power side inner edge in cam shedding and make that cam is stressed to be rotated around cam center axle, cam inserts promotion gate stop inserts overcomes gate stop return spring makes gate stop around the axle rotation of position, gate stop top, after cam rotates to an angle again, when gate stop is subject to gate stop return spring restoring force to act on cam shedding one side cam inserts to rotate corresponding gate stop inserts, gate stop inserts resets and pushes against cam inserts, the cam shedding anglec of rotation is larger, now cam shedding is fixedly the realization that pushes against by cam inserts and gate stop inserts, snap close correspondence lock onto and in closed space, realizes snap close secondary locking Door lock,
2, unblanking in outside: on automotive door, operates automobile external opening door mechanism, by external-open pull bar, active force is reached to external-open rod head, by external-open rod head, promoting external-open rocking arm rotates around external-open rocker arm shaft, the rotation of external-open rocking arm promotes riveted joint unlatching lever thereon, open the corresponding riser of unblanking that promotes gate stop interlock plate of push pedal head on lever, the riser of unblanking promotes the rotation of gate stop interlock plate, gate stop interlock plate drives gate stop Control Shaft to move in gate stop control flume around gate stop locating shaft, gate stop Control Shaft drives gate stop to overcome the rotation of gate stop return spring restoring force around gate stop locating shaft, make pushing against of the disengagement of gate stop inserts and cam, by cam return spring restoring force, through cam return pin band moving cam, around cam center axle spinning reduction, make cam shedding rotation correspond to latch openings, now corresponding coincidence of cam shedding and latch openings is an open space, between snap close and door lock, without locking constraint, realize outside unlocking function, after unblanking, external-open rocking arm resets under the effect of returning pull-spring,
3, unblank in inside: in automobile, operate automobile inward opening door mechanism, by the interior pull bar of opening, in being reached, active force drives joint, by the interior joint of opening, open rocking arm in promoting and rotate around the interior rocker arm shaft of opening, inside open the corresponding external-open rocking arm opposite side that promotes of rocking arm rotation opposite side and make external-open rocking arm around the rotation of external-open rocker arm shaft, the rotation of external-open rocking arm realizes inner unlocking function and unblanks identical with outside;
4, outside shuts: in automobile external operation, control lock door mechanism outside automobile, by lock core pull bar, active force is reached to outer latching connector, by outer latching connector, promoting locking transmission arm rotates around the interior rocker arm shaft of opening, locking transmission arm is successively through drive joint, locking trace, drive joint shift fork rocking arm rotates around shift fork rocker arm shaft, the locking push pedal of shift fork rocking arm opposite side is slided in the lock groove of opening the lever other end, by lock groove, drive and open lever and get around the riveting point of opening lever and external-open rocking arm and rotate, opening lever rotation departs from and the unblank corresponding realization pass lock function of riser of gate stop interlock plate push pedal head, now by external-open, interior opening mechanism can not correspondingly promote to unblank riser by push pedal head, open the locking mouth of lever and the anti-error riser of gate stop interlock plate is corresponding simultaneously,
5, inside shuts: in automotive interior operation, control lock door mechanism in automobile, promote locking transmission arm rotate around the interior rocker arm shaft of opening by interior latching connector, close lock function shut identical with outside by the locking push pedal realization inside of shift fork rocking arm;
6, anti-error shutting: externally or when inside shuts, open the locking mouth of lever and the anti-error riser of gate stop interlock plate corresponding, when the latch openings of the corresponding door lock of snap close snaps in, snap close rotates by actuated by cams gate stop, gate stop rotarily drives the rotation of gate stop interlock plate, the corresponding locking mouth that promotes unlatching lever of anti-error riser of gate stop interlock plate makes to open lever rotation, opening lever rotates to the riser position of unblanking of the corresponding gate stop interlock plate of push pedal head, even if now snap close snaps in and shuts, throw away and can unblank by opening the riser realization of unblanking of the push pedal head promotion gate stop interlock plate of lever, there is anti-error pass lock function,
7, the anti-skidding buffering of snap close: when the latch openings of the corresponding door lock of snap close snaps in, to snap in dynamics larger as snap close, along slide block axle elastic reset, works the snap close buffer stopper and by the effect of snap close buffer stopper shock absorbing power of leading by the slide block return spring of slide block; The intrinsic cam buffer stopper of the lock body impact force that resets when cam is unblanked plays cushioning effect, and the intrinsic gate stop buffer stopper of the lock body impact force that resets when gate stop is unblanked plays cushioning effect, extends lock body application life.
The present invention adopts the embedding mouth of cam and inserts to push against with gate stop the classification locking that realizes snap close respectively, in employing, opening mechanism is used in the corresponding gate stop interlock plate rotation of external-open mechanism components transmission unlatching lever realization, external-open door lock, in employing, outer lock mechanism shares locking transmission arm within shift fork rocking-arm driving unlatching lever is thrown off corresponding gate stop interlock plate realization, outer spring lock, coordinate the corresponding corresponding unlatching of the anti-error riser lever of opening lever while gate stop interlock plate of the riser disengagement of unblanking of gate stop interlock plate to realize error locking proof function, this door lock connects compact, firmly, snap close transmission is stable, precisely, shock resistance, error preventing lock, practical, long service life.
