Description
Technical field
The utility model relates to a kind of door lock, is opening mechanism in a kind of door lock in automobile body specifically.
Background technology
Car door is as an important component part of body of a motor car, meet people and goods's turnover, having sealing is isolated from the outside interior of body, require in addition car door safe and reliable, when driving a vehicle or bumping, car door can not opened automatically, collision can normally be opened after occurring, and has good theftproof performance.For meeting these, require, except needs car door and vehicle body have rational structure and suitable intensity, also to require to have safe and reliable lock system.Lock body and fastener system are comprised of mate and actuating element, and the common structure form of mate has rotor buckle-type and pinion and-rack, because snap-lock engagement is reliable, so can bear larger load, assembly precision are required lowlyer generally to be adopted.Existing door lock in automobile body mostly adopts rotor fastening type structure, and its weak point is: it is larger that snap close snaps in the interior impact of lock body, easily causes rotor skew and the long-term rotary buckle of rotor, and the snap close that causes easy to wear is malfunctioning; Fastener system transmission lock body inner rotor core is complicated, and driving parts is many, and lock system is made difficulty, and it is large that integral body takies automotive door space.
Summary of the invention
For grille body complex structure in prior art, drive disk assembly is many, making is difficult, it is large to take installing space, use easy to wear, impact failure, the deficiency that application life is short, the utility model provides a kind of drive mechanism simple, compact, easy to make, take installing space little, there are damping of shocks, the wearing and tearing of resistance to buckle, opening mechanism in the middle grille body of long service life.
The technical solution adopted in the utility model is: in a kind of middle grille body, opening mechanism is opened joint and Nei Kai rocking arm in comprising, inside open rocking arm through in open rocker arm shaft and be riveted on lock body seat board, inside open rocking arm and drive joint in connecting, inside open rocker arm shaft one side in open open in arranging on rocking arm on the spacing corresponding external-open rocker arm shaft opposite side external-open rocking arm of push pedal in open plate.
The groundwork state of the utility model door lock 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, 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, driving internal lock shifting block to stir locking interlock plate opposite side rotates around locking interlock plate axle, 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 unblank, realize the inner lock function that closes.
6, 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 utility model adopt ratchet, the one-level of ratchet, secondary elasticity to push against to realize snap close classification locking, adopt in opening mechanism use the interlock plate rotation of unblanking of external-open mechanism components transmission external-open push pedal correspondence and realize inside and outside lock and open the door, adopt the push pedal of interlock assembly transmission external-open to throw off the correspondence interlock plate of unblanking to realize internal lock and close the door, it is compact, firm that this door lock connects, snap close transmission is stable, accurate, shock resistance, practical, long service life.
