Introduce a kind of specific embodiment of the present utility model below by Fig. 1 to 10.
Shown in Fig. 1 to 10, a kind of mini quiet lock body of the present utility model comprises: dead bolt 1, ratchet 2, three lock body mounting sleeves 3, ratchet spring 4, latch bolt spring 5, lock body housing 6, transition lever 8 and metallic supports 9; Described dead bolt 1 is articulated in the described lock body housing 6 by lock body mounting sleeve 3, and described dead bolt 1 fixes with latch bolt spring 5; Described ratchet 2 is articulated in the described lock body housing 6 by lock body mounting sleeve 3, and described ratchet 2 is meshed with described dead bolt 1, and described ratchet 2 fixes with ratchet spring 4; The described ratchet 2 of described transition lever 8 engagements, described metallic support 9 cover caps are on the top of described dead bolt 1 and ratchet 2; Described dead bolt 1, ratchet 2 and lock body housing 6 contacted edges are arranged with some cushion holes, buffer protrusion or buffering slope.Also comprise lock body housing buffer stopper 7, be arranged in the described lock body housing 6, restriction dead bolt 1 position of engagement.
On the described dead bolt 1, the edge that contacts with described lock body housing 6 is provided with cushion hole a, b, and the edge that contacts with described ratchet 2 is provided with cushion hole c, g; On the described lock body housing 6, the edge that contacts with described dead bolt 1 is provided with at least one cushion hole i; On the described ratchet 2, the edge that contacts with described dead bolt 1 is provided with cushion hole d, and the edge that contacts with described lock body mounting sleeve 3 is provided with cushion hole e.
The edge that contacts with described ratchet 2 on the described dead bolt 1 is provided with the buffer protrusion f of restriction ratchet 2 positions of engagement.The edge that contacts with metallic support 9 on the described ratchet 2 is provided with buffering slope h.Described cushion hole is the prolate hole that is complementary with the edge.
Concrete use of the present utility model is as follows:
Further specify the utility model below in conjunction with accompanying drawing.Fig. 1 to Figure 10 mainly shows the utility model key position frame for movement, and unlatching, half lock of automobile-used door lock, the task of full lock are mainly finished in this position.
Wherein, the actuating logic of lock body parts closes and is during unlatching: the passenger is by the pulling door handle, trigger door lock backguy and a series of lock body internal part, drive transition lever 8, transition lever 8 pulling ratchets 2, ratchet 2 overcomes the torsion that ratchet spring 4 provides, the dead bolt 1 that release is engaged with, dead bolt 1 hightail the engagement with ratchet 2 under the promotion of latch bolt spring 5, open with certain speed, finally stop at the enable possition down the spacing of lock body housing 6, the passenger discharges door handle, ratchet relies on the edge of dead bolt, is positioned at the enable possition.
At present, car load company and passenger have relatively high expectations to the sound of the opening and closing of car door lock, and main feedback exists sound sharpness≤3.60; (acum), loudness≤18.0; (sone), sound pressure level≤67; (dBA).
The main flow door lock of domestic market is difficult to satisfy high like this requirement, this utility model has designed cushion hole a after by research and analysis on dead bolt 1 and lock body housing 6, cushion hole b and cushion hole i, to slow down car door when opening, dead bolt is to the impact strength of lock body housing, reduce the vibration frequency between two parts, to reach sharpness that improves sound and the purpose that reduces loudness.
The actuating logic of partly locking process lock body parts closes and to be: the passenger is with than the low velocity closed door, car door drives automobile-used Door-lock bolt 1 with lower speed, dead bolt 1 bump snap close, the torsion that the impact force of car door produces on dead bolt overcomes the elastic force of latch bolt spring 5, make dead bolt rotate to dead bolt half lock position around lock body mounting sleeve 3, at this moment, ratchet 2 is under the effect of ratchet spring 4 torsion, ratchet rotates to its fastening position rapidly, with engagement of dead bolt half lock-bit and the final dead bolt that pins.
Equally, comprehensive product know-how is in half lock position at the car door door lock, and this utility model has designed cushion hole c on dead bolt 1 and ratchet 2, cushion hole d, cushion hole e, buffer attribute g, buffering slope h.Wherein cushion hole c and d are in order to reduce ratchet and dead bolt at the impact sound between when engagement; Cushion hole e is in order to reduce between ratchet 2 and the lock body mounting sleeve 3, to rotate to the impact sound of its fastening position and the generation of lock body mounting sleeve at ratchet rapidly; When buffer attribute g is closing of the door, the sound that produces in order to reduce dead bolt bump snap close; Buffering slope h is in order to strengthen the frictional force between ratchet 2 and the metallic support 9, to reduce ratchet return speed, reducing the impact energy of ratchet and see that Fig. 9 describes.These five buffer attributes, dead bolt when partly locking, the sound that produces because of bump between ratchet and lock body mounting sleeve and dead bolt and the snap close, and the sharpness of sound and sound pressure level from being reduced in lock body in varying degrees.
The actuating logic of full lock process lock body parts closes: the passenger is closed door at a relatively high speed, car door drives automobile-used Door-lock bolt 1 with higher speed, dead bolt 1 bump snap close, the torsion that the impact force of car door produces on dead bolt overcomes the elastic force of latch bolt spring 5, make dead bolt rotate to dead bolt full lock position around lock body mounting sleeve 3, at this moment, ratchet 2 is under the effect of ratchet spring 4 torsion, ratchet rotates to its fastening position rapidly, with engagement of dead bolt full lock position and the final dead bolt that pins.
Analyze this kind situation, be in the full lock position at the car door door lock, this utility model is at cushion hole c, cushion hole d, and cushion hole e on the buffering h basis, slope, has increased buffer protrusion f, simultaneously, on lock body housing 6, has designed lock body housing buffer stopper 9.Wherein, the main effect of buffer protrusion f is, uses design feature, and the position of engagement of having limited ratchet 2 makes it weakened greatly with the Impact energy of lock body mounting sleeve 3, reduces the effect of clashing into the sound intensity between ratchet and the lock body mounting sleeve to reach.9 effect is the plastics that the elastic body by flexibility replaces hard, and the rolling momentum purpose of restriction dead bolt in the full lock position design in order to reach, and like this, do not had unmanageable rocking, and just do not have unmanageable sound generating (seeing that specifically Fig. 5 describes).
Pass through these all buffer attributes like this, and the application of lock body housing buffer stopper, effective reaching reduces lock body is opening, half lock, and the sound in the full lock process is for lifting client's satisfaction is made very big contribution.At present, the manual exemplar of this kind design has been made and finished, and is quiet respond well, in sound sharpness≤3.60; (acum), loudness≤18.0; (sone), sound pressure level≤67; (dBA) aspect all can meet the demands.
In summary, owing to adopted above-mentioned technology, mini quiet lock body of the present utility model is by the new moving component structure of utility model, improve the mated condition of part,, reduce the direct impact contact between the movement parts to reach the dead bolt that makes automobile-used automatically controlled integrated door lock and ratchet under the duty of routine, make component movement milder, the final noise that reduces automobile door lock generation when work, the organoleptic quality of raising vehicle is improved customer satisfaction.
Above-described embodiment only is used to illustrate technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, can not only limit claim of the present utility model with present embodiment, be all equal variation or modifications of doing according to the spirit that the utility model disclosed, still drop in the claim of the present utility model.
