Abstract
The utility model discloses a kind of reduction to close the door the door lock ratchet structure of sound, the ratchet of described door lock is formed with the teeth groove that can engage with ratchet, the sidewall of described ratchet teeth groove and ratchet mesh regional is provided with buffer structure, the utility model arranges buffer structure by the region of engaging with ratchet at ratchet, the ratchet iron core of door lock and the impact force of ratchet iron core when reducing door contact interrupter by buffer structure, play the effect reducing noise, and adopt plastic structure preferentially to contact by ratchet teeth groove local, reduce the ratchet iron core of door lock during door contact interrupter and the impact force of ratchet iron core, and then play the effect reducing noise, structure is simple, save material, vibration-absorbing and reducing noise is effective.
Description
Technical field
The utility model relates to a kind of automobile door lock mechanism, and particularly a kind of reduction is closed the door the door lock ratchet structure of sound.
Background technology
The structure of the click engagement in conventional door lock adopts iron core directly to touch the mode of iron core, and this structure is in the process of closing of the door, and the impact due to the counter spring force of inertia and relevant door lock inside can produce iron core and touch iron core and impact concussion noise.
Utility model content
In order to make up above deficiency, the utility model provides a kind of reduction and to close the door the door lock ratchet structure of sound, and this reduction is closed the door the door lock ratchet structure of sound concussion noise when effectively reducing vehicle switch door.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of reduction is closed the door the door lock ratchet structure of sound, the ratchet of described door lock is formed with the teeth groove that can engage with ratchet, the sidewall of described ratchet teeth groove and ratchet mesh regional is provided with buffer structure.
As further improvement of the utility model, described buffer structure is just positioned on the engagement position that ratchet and ratchet just started to contact.
As further improvement of the utility model, described buffer structure is the elastomeric material that fixed packet is overlying on hook tooth rooved face.
As further improvement of the utility model, described buffer structure is the plastic structure being positioned at side, hook tooth channel opening position or both sides.
As further improvement of the utility model, described ratchet is also provided with buffer, this buffer is just positioned at ratchet and engages on position with ratchet.
As further improvement of the utility model, described ratchet and ratchet engage the portion faces contacted and are fixed with plastic structure.
Said structure can be applied on car door, boot door, realizes closing the door the reduction of noise.
Advantageous Effects of the present utility model is: the utility model arranges buffer structure by the region of engaging with ratchet at ratchet, the ratchet iron core of door lock and the impact force of ratchet iron core when reducing door contact interrupter by buffer structure, play the effect reducing noise, and adopt plastic structure preferentially to contact by ratchet teeth groove local, reduce the ratchet iron core of door lock during door contact interrupter and the impact force of ratchet iron core, and then play the effect reducing noise, structure is simple, save material, vibration-absorbing and reducing noise is effective.

Detailed description of the invention
Embodiment: a kind of reduction is closed the door door lock ratchet 1 structure of sound, and the ratchet 1 of described door lock is formed with the teeth groove 3 that can engage with ratchet 2, described ratchet 1 teeth groove 3 is provided with buffer structure 4 with the sidewall of ratchet 2 mesh regional.
At closing time, the region that ratchet 1 engages with ratchet 2, due to the effect of buffer structure 4, reduces ratchet 1 iron core of door lock during door contact interrupter and the impact force of ratchet 2 iron core to automobile, plays the effect reducing noise.
Described buffer structure 4 is just positioned on the engagement position that ratchet 1 and ratchet 2 just started to contact, and by buffer structure 4 Limited contact, ratchet 1 iron core of door lock and the impact force of ratchet 2 iron core when reducing door contact interrupter, structure is simple, saving material.
Described buffer structure 4 is overlying on the elastomeric material on ratchet 1 teeth groove 3 surface for fixed packet, and elastomeric material plays the effect of buffering shock-absorbing, effectively can reduce the impact force of ratchet 1 iron core and ratchet 2 iron core, reduction noise.
Described buffer structure 4 for being positioned at the plastic structure of ratchet 1 teeth groove 3 opening side or both sides, except plastic structure, can also rubber-coated material etc.
Described ratchet 2 is also provided with buffer, and this buffer is just positioned at ratchet 2 and engages on position with ratchet 1, and ratchet 2 also arranges buffer, further reduces the impact force of ratchet 1 iron core and ratchet 2 iron core, reduces noise.
Described ratchet 2 engages with ratchet 1 portion faces contacted and is fixed with plastic structure.
Said structure can be applied on car door, boot door, realizes closing the door the reduction of noise.
