Description

Middle door lock gripping mechanism

Technical field

The present invention relates to a kind of door lock, is a kind of door lock in automobile 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.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 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 door latch structure in prior art is complicated, drive disk assembly is many, making is difficult, it is large to take installing space, use easy to wear, impact failure, application life is short, deficiency without error locking proof function, the invention 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, the middle door lock gripping mechanism of long service life.

The technical solution used in the present invention is: a kind of middle door lock gripping mechanism, is characterized in that, comprise cam, cam center axle, cam return pin, cam return spring, gate stop, gate stop locating shaft, gate stop Control Shaft, gate stop return spring, slide block, cam buffer stopper, gate stop buffer stopper and snap close buffer stopper, described cam is connected on lock body body through cam center axle, cam is provided with the cam shedding of corresponding latch openings, cam shedding one side is provided with cam inserts and cam embedding mouth successively, between cam shedding opposite side and lock body body, be provided with cam buffer stopper, the vertical cam return pin that connects on the bottom surface of cam, lock body body is provided with one and take the arc return groove that cam center axle is the center of circle, in arc return groove, be provided with a cam return spring, cam return pin is placed in arc return groove and is by cam return spring and holds out against state, described gate stop is respectively through gate stop locating shaft, gate stop Control Shaft is connected on lock body body, the gate stop end angle that wears gate stop Control Shaft one side is provided with gate stop inserts, the gate stop that wears gate stop Control Shaft one side holds out against lock body body through gate stop return spring makes gate stop inserts and cam inserts and cam embedding mouth be respectively clamping or disengaged condition, lock body body is provided with the gate stop buffer stopper that is placed in corresponding gate stop inserts between cam and gate stop, described slide block and snap close buffer stopper are arranged on lock body body, the setting corresponding to latch openings of snap close buffer stopper, slide block be guiding snap close buffer stopper state corresponding to latch openings.

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, open: on automotive door, operate, by rod head, pull and open rocking arm and get around and open rivet and rotate, unlatching rocking arm opposite side gets around and opens the corresponding gate stop interlock plate opposite side that promotes of rivet, gate stop interlock plate rotates around gate stop locating shaft, gate stop interlock plate one side 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 open function.

The present invention adopt the embedding mouth of cam and inserts respectively with gate stop push against realize snap close classification locking, adopt and open the corresponding gate stop interlock plate rotation of rocking arm and realize unlatching locking function, it is compact, firm that this door lock connects, and snap close transmission is stable, accurate, shock resistance, practical, long service life.
