Description
Technical field
The present invention relates to a kind of door lock, is a kind of automobile tail gate lock gripping mechanism 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.On the automobile with tail-gate, automobile tail is generally to use for storing articles in from outside to automobile, switching manipulation on automobile tail gate only comprises inside and shuts with outside and unblank, the lock of general-utility car side door has inside and outside switch lock and anti-error function, complex structure, make, use cost is high, be not suitable for automobile tail gate and use.
Summary of the invention
The invention provides a kind of drive mechanism simple, compact, easy to make, cost is low, can meet automobile tail gate inside and shut the tail-gate lock gripping mechanism with outside unlocking function requirement.
The technical solution used in the present invention is: a kind of tail-gate lock gripping mechanism, comprise ratchet, ratchet central axis, ratchet return pin, ratchet return spring, ratchet, ratchet central axis, ratchet return pin and ratchet return spring, described ratchet is connected on lock body through ratchet central axis, ratchet is connected on lock body through ratchet central axis, ratchet is provided with the ratchet opening of corresponding latch openings, ratchet opening is provided with ratchet inserts and ratchet embedding mouth towards the nearside of ratchet rotation, the vertical ratchet return pin that connects in ratchet plane, lock body or lower cover are provided with one and take the arc ratchet return groove that ratchet central axis is the center of circle, in ratchet return groove, be provided with ratchet return spring, ratchet return pin is placed in ratchet return groove and is by ratchet return spring and holds out against state, described ratchet one side is provided with ratchet inserts, ratchet opposite side vertically connects ratchet return pin, lock body or lower cover are provided with one and take the arc ratchet return groove that ratchet central axis is the center of circle, in ratchet return groove, be provided with ratchet return spring, ratchet return pin is placed in ratchet return groove and is by ratchet return spring and holds out against state, the any side of ratchet is provided with ratchet and cuts somebody's hair, ratchet be by ratchet cut somebody's hair promote rotation ratchet inserts and ratchet embedding mouth, ratchet inserts are clamped successively or with ratchet inserts, ratchet embedding mouth successively disengaged condition.
The groundwork state of door lock of the present invention comprises:
1, tail-gate snap close snaps in tail-gate lock interlocking: when tail-gate is closed, the corresponding tail-gate lock of tail-gate snap close latch openings snaps in, tail-gate snap close enters ratchet opening and pressing promotes ratchet opening inner side edge, ratchet is stressed to be rotated around ratchet central axis, the ratchet inserts that ratchet rotation pushes against ratchet makes ratchet rotate around ratchet central axis, ratchet is stressed rotate to an angle after, when ratchet is subject to ratchet return spring to act on ratchet opening one gemmule wheel embedding mouth and rotate corresponding ratchet inserts the restoring force of ratchet return pin, ratchet inserts resets and supports into ratchet embedding mouth, 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 tail-gate lock, wherein ratchet opening is fixedly to push against realization by ratchet embedding mouth and ratchet inserts, 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 central axis, ratchet inserts promotion ratchet inserts overcomes ratchet return spring makes ratchet around the axle rotation of position, ratchet top, after ratchet rotates to an angle again, when ratchet is subject to ratchet return spring restoring force to act on ratchet opening one gemmule wheel inserts to rotate corresponding ratchet inserts, ratchet inserts resets and pushes against ratchet inserts, the ratchet opening anglec of rotation is larger, now ratchet opening is fixedly the realization that pushes against by ratchet inserts and ratchet inserts, snap close correspondence lock onto and in closed space, realizes snap close secondary locking tail-gate lock, in snap close secondary latch, be tightened to behind position, corresponding contacting travel switch assembly, provides automobile tail gate to shut information completely,
2, unblanking in outside: handles automobile tail gate handle transmission external-open joint, by external-open joint, drive external-open rocking arm around support shaft, to rotate on support, external-open at the corresponding external-open rocking arm of the external-open column of locking linked block is cut somebody's hair under state, the external-open of external-open rocking arm is cut somebody's hair successively through external-open column, locking linked block, locking interlock opening drives moving arm to rotate around support shaft, moving arm rotarily drives to be stirred the corresponding ratchet that promotes of head and cuts somebody's hair and make ratchet overcome the rotation of ratchet return spring restoring force through ratchet return pin, ratchet inserts is thrown off ratchet inserts and ratchet embedding mouth successively, ratchet drives ratchet to make the rotation of ratchet opening correspond to latch openings around ratchet central axis spinning reduction by ratchet return spring restoring force through ratchet return pin, now corresponding coincidence of ratchet opening and latch openings is an open space, between tail-gate snap close and tail-gate lock, without locking constraint, realize outside unlocking function,
3, inside shuts: after automobile tail gate is closed or by travel switch assembly, provide automobile tail gate to shut after information completely, by automobile middle control, control lock core rod head, lock core rod head drives locking rocking arm around locking rocker arm shaft, to rotate on support, by the lock groove on locking rocking arm, drive the locking interlock opening on internal lock column and moving arm jointly to retrain driving locking linked block, the locking linked block external-open that makes the external-open column of locking linked block throw off external-open rocking arm that slides in locking interlock opening is cut somebody's hair, now handle automobile tail gate handle transmission external-open rocking arm, external-open rocking arm external-open cut somebody's hair and ratchet between without transmission, external control cannot be opened ratchet opening, thereby realize the inner lock function that closes.
4, fore shaft buffering: when snap close secondary is locked, snap close further snaps in latch openings, through left and right slide block and buffering block buffering tail-gate snap close impact force; When ratchet resets rotation under the effect of ratchet return spring restoring force, by ratchet snubber block, cushion ratchet to lock body impact force; When locking rocking arm resets rotation under lock location rocking arm return spring restoring force effect, by shock-absorbing sleeve buffering locking rocking arm, to support impact force, effectively guaranteed to use safety, stability, increase the service life.
The present invention stirs ratchet by moving arm and pushes against with the embedding mouth of ratchet and inserts the classification that realizes snap close respectively and lock, coordinate locking rocking arm and moving arm jointly to drive locking linked block to be thrown off by locking linked block and corresponding interlock external-open rocking arm and moving arm are realized inside and shut and outside unlocking function, it is compact, firm that this door lock connects, snap close transmission is stable, accurate, shock resistance, practical, long service life.
