The utility model discloses an annular shock attenuation shell fragment of S3M lock cardboard, the lock include bedplate, pawl rivet, pawl, cardboard and cardboard rivet, the pawl passes through the riveting of pawl rivet on the bedplate, the cardboard passes through the riveting of cardboard rivet on the bedplate, the cardboard is moulded for the package to the cardboard, and the cardboard arc end of keeping away from the pawl is established to annular shock attenuation shell fragment. The cardboard adopts the shock attenuation chip architecture, reduce the cardboard the door open with turn -off transient and driving motor vehicles in the axial float, reduce the vibration improves the sound quality, has promoted the customer satisfaction effectively.

Description

A kind of annular damping shell fragment of S3M door lock clamp

Technical field

This utility model relates to the annular damping shell fragment of a kind of S3M door lock clamp, belongs to auto-parts technical field.

Background technology

In current like product side door lock maintaining body, clamp does not all have shock-damping structure.During in order to ensure that door lock engages, clamp return is rapid and smooth, and the theoretical gap of clamp riveted joint is 0～0.8mm.Current this clamp without the subject matter of the side door lock maintaining body of shock-damping structure is:

Gap between clamp and side door lock seat board is relatively big, and clamp is relatively big along the axial shaking volume of clamp rivet, and in closing of the door, moment of unlatching and vehicle travel process, clamp can make axial float along clamp rivet shaft, causes abnormal sound.

Utility model content

Utility model purpose: for problems of the prior art with not enough, that is: the automobile side door lock overwhelming majority in the market is without clamp shock-damping structure, when clamp riveted joint gap is relatively larger, in closing of the door, moment of unlatching and vehicle travel process, clamp, due to the vibration of car door, all can make axial float along clamp rivet shaft.And in order to keep the motility of clamp, must keep again having between clamp and door lock seat board certain gap.So this play just inevitably result in contacting and collision of metal clamp and metal seat board, thus producing more sharp-pointed abnormal sound.This utility model provides a kind of simple in construction, the clamp shock-damping structure that reliability is high, requirement door lock sound quality is increasingly higher to meet client.

Technical scheme: the annular damping shell fragment of a kind of S3M door lock clamp, described door lock includes seat board, pawl rivet, ratchet, clamp and clamp rivet；Described ratchet is riveted on seat board by pawl rivet, and described clamp passes through clamp rivet on seat board；Described clamp is plastic clamp, and annular damping shell fragment is located at the clamp arc end away from ratchet.

Described annular damping shell fragment is the annular damping shell fragment that thermoplastic elastomer (TPE) TPE5562 material is made, this material is that a class not only has plastic processing characteristic but also have the functional rubber-plastics material of caoutchouc elasticity simultaneously, has good mechanical property within the scope of-40 DEG C～120 DEG C.

Described annular damping shell fragment is between clamp and side door lock seat board, and for wide 2.5mm, the span 30 °, arc length 6.28mm, the annular of thickness 0.5mm, initial position and card board plane are 102 °.

Beneficial effect: compared with prior art, the annular damping shell fragment of the S3M door lock clamp that this utility model provides, have the advantage that

1, clamp adopts vibration damping sheet structure, reduces clamp and opens and closes the axial float in moment and vehicle travel process at door, reduces vibration, improve sound quality, effectively improve CSAT.

2, the design of this clamp vibration damping sheet is simple, and compact in design, structure is sane.

3, the design is put into practice in the side door lock of the multiple vehicle of Dongfeng Automobile, and it is durable that door lock end goes through 100,000 switch gates, and shell fragment still can keep original function.

Accompanying drawing explanation

Fig. 1 is the structural representation of door lock；

Fig. 2 is the A-A sectional view of Fig. 1；

Fig. 3 is axis side view such as grade of the present utility model；

Fig. 4 is the three-view diagram of this utility model clamp.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, it is further elucidated with this utility model.

As shown in Figure 1: the maintaining body of door lock is made up of seat board 1, pawl rivet 2, ratchet 3, clamp 4, clamp rivet 5.Ratchet 3 is riveted on seat board 1 by pawl rivet 2, and clamp 4 is connected on seat board 1 by clamp rivet riveting 5.In car door open and close process and in vehicle travel process, due to the vibration of car door, the clamp 4 in maintaining body can make axial float along clamp rivet 5, and play can cause contact and the collision of the clamp of metal and the seat board of metal, thus producing abnormal sound, affect the comfortableness that user drives.

What Fig. 2 described is that clamp 4 makes the amplitude of axial float along clamp rivet 5 axle, and the theoretical gap of clamp 4 riveted joint is 0～0.3mm, adds the impact of clamp 4 radius, and there is the axial float of maximum 1.45mm at the edge of clamp 4.

Door lock is being opened and in closing course, relation due to the deadweight of car door and door hinge, door device can produce vibration, this vibration can be delivered on door lock, now, if clamp 4 rivets gap relatively greatly, clamp 4 can produce to make axial float around clamp rivet 5, play causes clamp 4 and the contact of door lock seat board 1, thus producing abnormal sound.Although it should be noted that this abnormal sound itself is little, but as source of sound, under the effect of this good amplifier of car door cavity, can seem obvious, very easily cause client to complain.

As shown in Figure 3-4, clamp 4 is plastic clamp 4, and annular damping shell fragment 6 is located at the clamp 4 arc end away from ratchet 3.

Annular damping shell fragment 6 is between clamp 4 and side door lock seat board 1, and for wide 2.5mm, the span 30 °, arc length 6.28mm, the annular of thickness 0.5mm, initial position and clamp 4 plane are 102 °.

The material of annular damping shell fragment 6 is thermoplastic elastomer (TPE) TPE5562, and this material is that a class not only has plastic processing characteristic but also have the functional rubber-plastics material of caoutchouc elasticity simultaneously, has good mechanical property within the scope of-40 DEG C～120 DEG C.
