As shown in Fig. 5 to 12, screens linkage comprises clamp 2 and lock pawl 3, clamp 2 is fixed with clamp axle 22, clamp axle 22 is set with cursor 23, and cursor 23 is provided with the first torsion spring 24 be connected with clamp 2, and clamp axle 22 upper end is connected with cover plate 6 one end; The other end of described cover plate 6 is fixedly connected with the lock pawl 3 of its underpart, and be provided with the co-axially fixed release arm 4 with lock pawl 3 above cover plate 6, described release arm 4 is provided with the first position-limit mechanism 41; Described cursor 23 upper end is provided with the second position-limit mechanism 21 extended to above cover plate 6; Be provided with screens bar 1 above described cover plate 6, screens bar 1 is connected with cover plate 6 by the second torsion spring 5, and screens bar 1 two ends are connected with the first position-limit mechanism 41, second position-limit mechanism 21 respectively.Described first position-limit mechanism 4 for cross section be fan-shaped column structure, it comprises intrados, extrados, lateral surface and medial surface; Described second position-limit mechanism 21 is through the deep-slotted chip breaker be opened on cover plate 6 and extend to above cover plate 6 and be connected with screens bar 1.
In automobile door lock opening process, the motion process of door lock is as follows:
Fig. 5 is the phantom drawing that clamp 2 and lock pawl 3 are engaged on full lock position.Clamp 2 and lock pawl 3 are engaged on full lock position, and the extrados of the first position-limit mechanism 41 on release arm 4 limits screens bar 1, stop screens bar 1 at the motive force move under influence of the second torsion spring 5, screens bar 1 is limited in initial position.
Fig. 6 is the phantom drawing of lock pawl 3 when discharging clamp 2.Release arm 4 and lock pawl 3 are fixed together, and release arm 4 applies the power of opening direction, and lock pawl 3 moves together with release arm 4; Discharge screens bar 1 after lock pawl 3 turns an angle, screens bar 1 rotates under the motive force effect of the second torsion spring 5, and the medial surface engagement of the first position-limit mechanism 41 on release arm 4, and screens bar 1 supports release arm 4, prevents lock pawl 3 return.
Fig. 7 is the phantom drawing that clamp 2 and lock pawl 3 are engaged on half lock position.Clamp 2 rotates to enable possition under the effect of the first torsion spring 24; When clamp 2 turns to half lock position, screens bar 1 is still in the medial surface engagement with the first position-limit mechanism 41 on release arm 4, and lock pawl 3 still can not return and clamp 2 engage in half lock position.
Fig. 8 is the phantom drawing of screens bar 1 when discharging lock pawl 3.Clamp 2 continues to rotate to enable possition under the promotion of the first torsion spring 24, and the second position-limit mechanism 21 on clamp 2 promotes screens bar 1 and moves simultaneously, and screens bar 1 is fewer and feweri with the mesh volume of the medial surface of the first position-limit mechanism 41 on release arm.When moving to a position under the promotion of screens bar 1 second position-limit mechanism 21 on clamp 2, the medial surface of the first position-limit mechanism 41 on screens bar 1 and release arm 4 departs from engagement, release arm 4 and lock pawl 3 are released, lock pawl 3 is return under the effect of return spring, but now clamp 2 has exceeded half lock position, the lock pawl 3 of return can not stop the opening movement of clamp 2.
Fig. 9 is clamp 2 and lock pawl 3 phantom drawing in clamp 2 full open position.Clamp 2 gets back to enable possition under the effect of the first torsion spring 24, and on clamp 2, the second position-limit mechanism 21 limits screens bar 1 simultaneously, stops screens bar 1 to rotate under the promotion of the second torsion spring 5.Release arm 4 and lock pawl 3 are fixed together, and release arm 4 moves together with lock pawl 3, and lock pawl 3 is returned to initial position under the effect of return spring, and door lock is in full open position.
Automobile door lock is in locking process, and the motion process of door lock is as follows:
Figure 10 is the phantom drawing of locking process door lock.Clamp 2 rotates, and the second position-limit mechanism 21 on clamp 2 discharges screens bar 1, and screens bar 1 moves under the motive force effect of the second torsion spring 5 together with clamp 2.Clamp 2 rotates promotion lock pawl 3 simultaneously and rotates.When clamp 2 movement position arrives certain position, the extrados that screens bar 1 is released the first position-limit mechanism 41 on arm 4 stops, gag lever post 1 is no longer followed clamp 2 and moved together.
Figure 11 is that in locking process, clamp 2 moves to phantom drawing when to be engaged on half lock position with lock pawl 3.Clamp 2 rotates to half lock position, and the extrados that screens bar 1 is still released the first position-limit mechanism 41 on arm 4 stops, can not stop that lock pawl 3 return and clamp 2 engage, clamp 2 and lock pawl 3 can be engaged on half lock position normally, reach half lock locking function.
Figure 12 is that in locking process, clamp 2 moves to phantom drawing when to be engaged on full lock position with lock pawl 3.Continue to promote clamp 2, clamp 2 is rotated to full lock position.At clamp 2 from half lock position to the process that full lock position is moved, the extrados that screens bar 1 is released the first position-limit mechanism 41 on arm 4 always stops, can not stop that lock pawl 3 return and clamp 2 engage, clamp 2 rotates to full lock position, lock pawl 3 and clamp 2 engage, and reach the function of full locking.
Certainly, the invention of the door lock assembly that this Electronic Control is opened is not limited to the specific embodiment described by above-mentioned citing, those of ordinary skill in the art also can make other equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention: screens bar 1 is not limited to rotation, also comprise other motion, such as translation, elastic deformation etc., can stop lock pawl 3 and clamp 2 to engage when making screens bar 1 clamp 2 in opening process move to half lock position; Drive the second torsion spring 5 of screens bar 1 to be not limited to torsion spring, also comprise extension spring, stage clip etc. to make the elastic device of screens bar 1 motion; Being not limited to the first position-limit mechanism 41 on release arm 4 with the first position-limit mechanism 41 on the release arm 4 that screens bar 1 engages, can also be the position limiting structure be arranged on lock pawl 3 or the releasing structure linked with lock pawl.Such as only use a controller, instead of use four controllers to realize the specific embodiment of above-mentioned citing description as above-mentioned simultaneously, these equivalent variations or replacement are all included in the application's claim limited range.To double-door automobile, only need to arrange left front door electronic-controlled installation, electric performance device and right front door electronic-controlled installation, electric performance device.
