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 ratchet of lock body and compress in ratchet opening a side and make that ratchet is stressed to be rotated around ratchet shaft, ratchet shaft rotation pushes against ratchet pawl head makes ratchet rotate around pawl axis, ratchet is stressed rotate to an angle after, when ratchet is subject to ratchet spring restoring force to act on ratchet opening one side inner edge one-level ratchet inserts to rotate corresponding ratchet pawl head, ratchet pawl head resets and pushes against one-level ratchet inserts, ratchet opening 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 ratchet opening is fixedly to push against realization by one-level ratchet inserts and ratchet pawl head, its closed space towards another side of ratchet opening of opening direction without pushing against not stationary state, at snap close, continue to do power side inner edge in ratchet opening and make that ratchet is stressed to be rotated around ratchet shaft, ratchet shaft one-level ratchet inserts promotion ratchet pawl head overcomes ratchet spring makes ratchet rotate around pawl axis, after ratchet rotates to an angle again, when ratchet is subject to ratchet spring restoring force to act on ratchet opening opposite side secondary ratchet inserts to rotate corresponding ratchet pawl head, ratchet pawl head resets and pushes against secondary ratchet inserts, the ratchet opening anglec of rotation is larger, now ratchet opening is fixedly the realization that pushes against by secondary ratchet inserts and ratchet pawl head, its closed space towards another side of ratchet opening of opening direction in pushing against stationary state, 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 joint, by external-open joint, promoting external-open rocking arm rotates around external-open rocker arm shaft, the rotation of external-open rocking arm promotes to be articulated with the external-open push pedal of one side, push pedal head in external-open push pedal is corresponding promote the to unblank riser of unblanking of interlock plate, unblank riser through the pawl axis rotation of interlock plate drive disjunctor of unblanking, pawl axis drives ratchet to overcome the rotation of ratchet spring restoring force, the secondary of ratchet, one-level ratchet inserts is without pushing against, by ratchet spring restoring force, driving ratchet to reply spinning reduction makes the rotation of ratchet opening correspond to latch openings, now corresponding coincidence of ratchet opening and latch openings is an open space, between snap close and door lock, without locking constraint, realize outside unlocking function,
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 rocking arm rotarily drive one side in open push pedal corresponding promote external-open rocking arm opposite side in open plate, 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 external lock pull bar, active force is reached to outer latching connector, by outer latching connector, promoting external lock rocking arm rotates around locking interlock plate axle, external lock swivelling chute on external lock rocking arm is around the corresponding external lock hook plate promoting on locking interlock plate of locking interlock plate axle rotation, by the moving locking interlock plate of exterior lock hook strip, around locking interlock plate axle, rotate, locking push pedal on locking interlock plate is in the spacing push pedal groove that is arranged at external-open push pedal of coupling sleeve, locking push pedal promotes through push pedal groove the riser of unblanking that external-open push pedal push pedal head departs from the corresponding interlock plate of unblanking around the rotation of locking junction plate, now push pedal head can not correspondingly promote to unblank riser, cannot realize unlocking function, the push pedal head of external-open push pedal is still corresponding with the anti-error riser of the interlock plate of unblanking simultaneously,
5, inside shuts: in automotive interior operation, control lock door mechanism in automobile, by internal lock pull bar, active force is reached to interior latching connector, by interior latching connector, promoting internal lock rocking arm rotates around internal lock rocker arm shaft, by internal lock rocking arm, drive internal lock shifting block to stir locking interlock plate opposite side and rotate around locking interlock plate axle, by the locking push pedal realization inside of locking interlock plate one side, close lock function and shut identical with outside;
6, anti-error shutting: externally or when inside shuts, the push pedal head of external-open push pedal is still corresponding with the anti-error riser of the interlock plate of unblanking, when the latch openings of the corresponding door lock of snap close snaps in, snap close rotates by ratchet drive pawl, ratchet rotarily drives pawl axis rotation, the unblank interlock plate rotation of pawl axis interlock, the unblank corresponding push pedal head that promotes external-open push pedal of anti-error riser of interlock plate makes the push pedal head correspondence of external-open push pedal be pushed into the unblank riser position of unblanking of interlock plate of correspondence, even if now snap close snaps in and shuts, can the push pedal head by external-open push pedal promote the to unblank riser of unblanking of interlock plate is realized and being unblanked, 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, as snap close, to snap in dynamics larger, easy off normal while promoting the rotation of ratchet compression ratchet spring, slider guide ratchet by corresponding ratchet and the setting of lock body inner chamber rotates, and by the sliding block spring of slide block, play elastic reset effect, can guarantee the stressed rotation of ratchet not off normal cause lock body to damage; The corresponding fore shaft opening of snap close buffer stopper arranging in lock body arranges, and when snap close snaps in impact lock body, plays shock absorbing effect, plays life-extending effect.
The present invention adopts ratchet, the one-level of ratchet, secondary elasticity pushes against the classification locking that realizes snap close, in adopting, opening mechanism is used external-open mechanism components transmission external-open push pedal correspondence and is unblanked in interlock plate rotation realizes, external-open door lock, adopting interlock assembly to use the push pedal of outer lock mechanism parts transmission external-open throws off correspondence and unblanks in interlock plate realizes, outer spring lock, coordinate the riser of unblanking of the interlock plate of unblanking to throw off simultaneously the unblank corresponding external-open push pedal of anti-error riser of interlock plate of corresponding external-open push pedal and realize error preventing lock, this door lock connects compact, firmly, snap close transmission is stable, precisely, shock resistance, error preventing lock, practical, long service life.
