A kind of specific embodiment of the present invention is introduced below by Fig. 1 to 11.
Embodiment 1
As shown in Fig. 1 to 11, a kind of automobile door lock actuator of the present invention, is provided with worm screw 2, open and-shut mode microswitch 3, motor 4, safety position microswitch 8, pinion 10, worm gear 12, insurance actuator arms 13, worm gear return spring 14, dead bolt 15, lock body mounting sleeve 16, ratchet 17 and ratchet Control Component 18 between actuator cover plate 1 and actuator housing 5.Described worm screw 2 is socketed on described motor 4, rotate with described motor 4, described worm gear 12 engages described worm screw 2, described pinion 10 is coaxially arranged with described worm gear 12, driven by described worm gear 12 and rotate, described worm gear 12 is engaged in one end of described insurance actuator arms 13, the other end connects described ratchet Control Component 18, described insurance actuator arms 13 is with the rotation of described pinion 10, upwards insurer to or separate insurer to motion, and drive described ratchet Control Component 18, adjust the state of described ratchet 17, described dead bolt 15 rotates around described lock body mounting sleeve 16, and engage with described ratchet 17, described open and-shut mode microswitch 3 is arranged in the movement travel of described insurance actuator arms 13, described safety position microswitch 8 is arranged in the rotational travel of described dead bolt 15.
When described insurance actuator arms 13 is with trend away from described safety position microswitch 8 direction motion by described pinion 10, described open and-shut mode microswitch 3 discharges return, feed back settling signal of insuring, described worm gear 12 return under the effect of described worm gear return spring 14.
When described insurance actuator arms 13 is with trend near described safety position microswitch 8 direction motion by described pinion 10, described open and-shut mode microswitch 3 compression close, feedback separates insurance settling signal, described worm gear 12 return under the effect of described worm gear return spring 14.
Be provided with boss 19 in described worm gear 12, described pinion 10 is provided with the chute 20 coordinating described boss 19, and when described boss 19 slides to described chute 20 end, described worm gear 12 drives described pinion 10 to rotate.Also comprise worm gear installation shaft 9, described worm gear 12 is socketed in described worm gear installation shaft 9.Also comprise buffer block of worm gear 11, be arranged on the side of described worm gear 12.Also comprise switch holder 6, be socketed described open and-shut mode microswitch 3.Also comprise switch holder 7, be socketed described safety position microswitch 8.
Continue referring to figs. 1 to 11, main presentation key position frame for movement of the present invention, this position mainly completes door lock for vehicles insurance and door lock for vehicles guard signal, opens and closes signal transmission task.When insuring, the actuating logic of actuator closes and is: passenger is insured to car door by operation key or button, after door lock for vehicles receives instruction of insuring, drive door-lock motor 4 action, worm screw 2 clockwise movement is driven under 4 effects, worm screw 2 moves and drives worm gear 12 to be rotated counterclockwise, worm gear 12 rotates to certain position and drives pinion 10 to rotate, eventually through gear movement drive insurance actuator arms 13 upwards insurer to motion, now, insurance shape microswitch 8 contact release return, feed back settling signal of insuring, complete this operation of insuring, worm gear 12 gets back to initial position under worm gear return spring 14 acts on.
This invention utilizes worm screw 2 by research and analysis, worm gear 12, drive connection between pinion 10, final drive insurance actuator arms 13 is toward moving away from safety position microswitch direction, by actuator housing 5 upper limit, mechanism carrys out controlled motion stroke, buffer block of worm gear 11 pairs of worm gears rotate and cushion, and reduce drive noise, and signal of finally insuring is fed back by insurance shape microswitch 8.
The actuating logic separating actuator during insurance closes and is: passenger carries out solution insurance by operation key or button to car door, after door lock for vehicles receives and separates insurance instruction, drive door-lock motor 4 action, worm screw 2 counterclockwise movement is driven under motor 4 acts on, 2. motion drives worm gear 12 to turn clockwise, worm gear 12 rotates to certain position and drives pinion 10 to rotate, drive insurance actuator arms 13 to solution insurer to motion eventually through gear movement, now, safety position microswitch 8 contact compression close, feedback separates insurance settling signal, complete this and separate safe operation, worm gear 12 gets back to initial position under worm gear return spring 14 acts on.
Equally, relatively to insure process, worm screw 2, worm gear 13, pinion 10 is toward rightabout motion, and by actuator housing 5 upper limit, mechanism carrys out controlled motion stroke, and the final insurance actuator arms 13 that drives is past near the motion of safety position microswitch 8 direction, pressing microswitch contact, feedback separates guard signal.
During unlatching, the actuating logic of signal transmission closes and is: passenger is by operating vehicle door handle, finally detent is driven by a series of actions, discharge the dead bolt be engaged with, dead bolt is under the effect of latch bolt spring, get back to enable possition, in this process, dead bolt, by microswitch 3 contact compression close, feeds back start signal.
During half lock, the actuating logic of signal transmission closes and is: passenger is with comparatively low velocity closed door, and make dead bolt rotate to dead bolt half lock position around lock body mounting sleeve by certain impact power, now, microswitch 3 contact is in compression close state, feedback start signal.
During full lock, the actuating logic of signal transmission closes and is: passenger's closed door, makes dead bolt rotate to the full lock position of dead bolt around lock body mounting sleeve by certain impact power, now, and microswitch 3 contact release return, feedback shutdown signal.
Changed by these structures like this, reduce lock body size, reduce actuator internal construction transmission failure risk, reduce insurance sound simultaneously, add the sensitivity of signal, promote the satisfaction of client.
In summary, automobile door lock actuator of the present invention replaces original stage-geared by adopting Worm Wheel System mode, reduce drive disk assembly, make more compact structure, avoid the risk that the easy clamping stagnation of gear drive lost efficacy, and because the steady noise of Worm Wheel System is little, reduce the sound of door lock for vehicles in insurance.In door lock for vehicles signal transmission, adopt microswitch to replace original slide vane structure, make layout compacter on the one hand, the sensitivity of signal transmission can be increased on the other hand.
Above-described embodiment is only for illustration of technological thought and the feature of this patent, its object is to enable those skilled in the art understand the content of this patent and implement according to this, the scope of the claims of this patent only can not be limited with the present embodiment, namely the equal change done of all spirit disclosed according to this patent or modification, still drop in the scope of the claims of this patent.
