Description
Technical field
The utility model relates to a kind of noise abatement electric lock locking mechanism of NAL electric door lock for vehicle, belongs to auto-parts technical field.
Background technology
The sound of current most domestic vehicle to the electric lock locking mechanism of door lock has strict requirement, and existing door lock electric lock locking mechanism action noise is large, this mainly lacks, and noise abatement design or mechanism action buffer index cause not, in addition, there is the electric lock locking mechanism complex structure of noise reduction function, realize cost higher.
Utility model content
Utility model object: for problems of the prior art with not enough, the utility model provides a kind of noise abatement electric lock locking mechanism of NAL electric door lock for vehicle, this electric lock locking mechanism structure is simple, be easy to realize noise reduction effect, overcome the defect that prior art complex structure, driving mechanism noise are too high.
Technical scheme: a kind of noise abatement electric lock locking mechanism of NAL electric door lock for vehicle, comprises lower cover, motor, worm screw, worm gear, pinion, spreadet spreadet wheel, locking connecting rod, opens connecting rod, Self-unlocking handle, ratchet, and clamp; Described motor, worm screw, worm gear, pinion and spreadet spreadet wheel are installed in down and cover; Described electric lock locking mechanism also comprises two for limiting the buffer stopper of spreadet spreadet wheel rotating distance, and buffer stopper is arranged on down and covers.
After motor energising, dress worm screw on the motor drives worm gear rotary motion, is meshed after worm gear rotates to an angle with pinion, and now pinion drives spreadet spreadet wheel to make shake double-direction turning movement, and the action of spreadet spreadet wheel is spacing depends on buffer stopper completely.Locking connecting rod is arranged in spreadet spreadet wheel hole and synchronously makes bidirectional-movement with spreadet spreadet wheel; Open connecting rod one end and be fixed on locking connecting rod, then the other end is fixed on Self-unlocking handle, locking connecting rod is made locking or is unlocked bidirectional-movement, and opening connecting rod when unlocked can connect ratchet, and other mechanism pulls open connecting rod causes ratchet disengaging ratchet to reach opening car door object; Open connecting rod can not connect ratchet ensure that other mechanisms cannot opening door lock when locking.Ratchet and clamp composition door lock closed-system, two parts are installed on seat board by rivet, can do the rotation of certain angle separately around rivet.
Further, described spreadet spreadet wheel is arranged on down by rivet and covers, and spreadet spreadet wheel rotates around rivet, covers under two buffer stoppers are arranged on spreadet spreadet wheel both sides, on the circumference that it is the center of circle that two buffer stoppers are positioned at rivet, radius is 19mm.
Further, described buffer stopper is provided with the square cylinder axially installing through hole.
Further, described square cylinder seamed edge and corner angle are seamed edge after rounding process and corner angle.
Operating principle: after the energising of electric door lock motor, driving link worm screw drives worm gear to rotate, worm gear rotates to an angle and touches pinion work, the spreadet spreadet wheel combined with pinion does angle rotary motion, spreadet spreadet wheel angle rotary stopper is buffer stopper, whole electric lock locking mechanism noise-decreasing device mainly buffer stopper plays a decisive role, spreadet spreadet wheel the is accomplished dynamic equilibrium of the moulding of buffer stopper and Position Design, even if the noise that system authority motion produces drops to minimum; The locking of spreadet spreadet wheel or the bidirectional-movement of unblock, then coupled locking connecting rod does synchronization action and unlatching connecting rod is departed from or touching ratchet, ratchet is made to be separated opening car door action with clamp if touching other mechanisms of ratchet can promote to open connecting rod, if depart from other mechanisms of ratchet cannot complete opening car door action.
Beneficial effect: compared with prior art, the noise abatement electric lock locking mechanism of the NAL electric door lock for vehicle that the utility model provides, structure is simple, compact, save taking up room of door lock, by two buffer stoppers to the restriction of the movement position of spreadet spreadet wheel, make spreadet spreadet wheel soft stop only reach the object of mechanism's noise abatement, be suitable for reliability high, the noise abatement of electric lock locking mechanism is obvious, can popularly promote.Prior art is do not have noise abatement design or noise abatement designed reliability strong mostly, part manufacture and height of controlling cost.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
As shown in Figure 1: the noise abatement electric lock locking mechanism of NAL electric door lock for vehicle, mainly comprise lower cover 1., motor 2., worm screw 3., worm gear 4., pinion 5., spreadet spreadet wheel 6., buffer stopper 7., locking connecting rod 8., open connecting rod 9., Self-unlocking handle 10., clamp, ratchet and seat board.
Motor 2., worm screw 3., worm gear 4., 6. 5. pinion be assembled in lower cover with spreadet spreadet wheel and 1. go up; Two buffer stoppers be 7. arranged on spreadet spreadet wheel 6. both sides lower cover 1. go up, for limiting spreadet spreadet wheel 6. rotating distance; 6. spreadet spreadet wheel is arranged on lower cover by rivet and 1. goes up, and 6. spreadet spreadet wheel rotates around rivet.
After 2. motor is energized, 3. worm screw drives worm gear 4. rotary motion, is 5. meshed after 4. worm gear rotates to an angle with pinion, and now pinion drives spreadet spreadet wheel 6. to make shake double-direction turning movement, and 7. spreadet spreadet wheel action is 6. spacing depends on buffer stopper completely.8. locking connecting rod is arranged on spreadet spreadet wheel and 6. 6. synchronously makes bidirectional-movement with spreadet spreadet wheel in hole; Open connecting rod and be 9. fixed on locking connecting rod 8. in one end, then Self-unlocking handle is fixed in other one end 10., 8. locking connecting rod is made locking or is unlocked bidirectional-movement, opens connecting rod when unlocked and 9. can connect ratchet, and 9. other mechanism pulls open connecting rod causes ratchet disengaging ratchet to reach opening car door object; Open connecting rod 9. can not connect ratchet ensure that other mechanisms cannot opening door lock when locking.Ratchet and clamp composition door lock closed-system, two parts are installed on seat board by rivet, can do the rotation of certain angle separately around rivet.
As shown in Figure 2, buffer stopper position design 7., in order to keep spreadet spreadet wheel rotation dynamic equilibrium 6., reduces motion oscillations and noise, on the circumference that 7. two buffer stoppers are positioned at rivet is the center of circle, radius is 19mm.Spreadet spreadet wheel is 6. once touch buffer stopper and 7. just stop in theory, but due to effect of inertia, 7. 6. spreadet spreadet wheel still can compress buffer stopper, the utility model design is to consider spreadet spreadet wheel dynamic equilibrium 6., so give the space design of 4 degree, namely be that 6. spreadet spreadet wheel contacts after 7. buffer stopper stop, in order to the inertia force effect 6. of anti-spreadet spreadet wheel, 6. spreadet spreadet wheel can also compress buffer stopper and 7. rotate 4 degree and reach final stopping.As shown in Figure 3, this utility model core two is buffer stopper shape-designings 7., this buffer stopper 7. medium design becomes to install through hole, exterior design becomes square body shape, square body seamed edge and corner angle are seamed edge after rounding process and corner angle, such spreadet spreadet wheel 6. and buffer stopper 7. between to collide be that linear contact lay can reach good noise reduction effect.
