Abstract

The invention discloses a kind of clamp reduces noise structure, described clamp is provided with the U-lag being fastened and connected with latch engagement post, it is formed with the wall of U-lag side and be snapped the passive impingement position that engagement post actively clashes into, the active impingement position of convolution active shock engagement post at a high speed after clamp is knocked is formed with U-lag opposite side wall, on described clamp, the active impingement position of U-lag is provided with buffer structure, the present invention passes through to arrange buffer structure on automobile side door lock clamp U-lag opening sidewalls, effectively reduce the noise that latch engagement post is produced with the collision of clamp U-lag opening sidewalls, again by the optimization processing to clamp U-lag open curve, greatly reduce the noise of closing the door of automobile side-door.

Description

Clamp reduces noise structure

Technical field

The present invention relates to a kind of automobile door lock mechanism, close the door the clamp structure design of sound quality particularly to a kind of automobile that improves.

Background technology

Through long-term development, automotive four-door two-lid is substantially all to be engaged with lock by closing piece makes four-door two-lid be maintained in its closed position, and wherein closing piece agent structure is substantially made up of with stop claw rotation clamp.Clamp typically has the ironware of inside and outside soft plastic bag to be grouped into.

Automobile door lock is in closed door, clamp moves with car door, latch engagement post slides into be realized engagement and closes the door in the U-lag of clamp, when latch engagement post has just contacted in clamp U-lag, initial collision clamp U-lag side wall 6 occurs, then latch engagement post continues to slip into, secondary collision clamp U-lag opposite side wall 7 then occurs, concussion for several times may clash between U-lag side wall 6 and opposite side wall 7, last latch engagement post just slides in the U-lag of clamp and fastens, and clamp has noise to produce with the collision of latch engagement post.This results in automobile at closing time, can be with the sharp sound of larger comparison.Typically the shock of clamp and latch engagement post can be reduced by the shape that fluting on this side clamp of U-lag side wall 6 is plastic arranges buffer unit 4 and optimizes U-shaped opening 3, improve sound.But said method door closing speed is very fast or lock with the change of closing piece relative position when, effect on driving birds is not good.

Content of the invention

In order to make up above deficiency, the invention provides a kind of clamp reduces the structure of noise, the structure that this clamp reduces noise is simple, effectively reduces noise when automobile side-door is closed.

The present invention be employed technical scheme comprise that to solve its technical problem：A kind of clamp reduces noise structure, described clamp is provided with the U-lag being fastened and connected with latch engagement post, it is formed with the wall of U-lag side and be snapped the passive impingement position that engagement post actively clashes into, the active impingement position of convolution active shock engagement post at a high speed after clamp is knocked is formed with U-lag opposite side wall, on described clamp, the active impingement position of U-lag is provided with buffer structure.

As a further improvement on the present invention, described buffer structure is the elongate holes on clamp, and this elongate holes is just located at outside the active impingement position of U-lag opposite side wall.

As a further improvement on the present invention, on described clamp, U-type groove opening is the smooth transition curve structure tangent with U-lag medial surface.

As a further improvement on the present invention, on described clamp, the passive impingement position of U-lag is provided with buffer unit.

As a further improvement on the present invention, described buffer unit is the elongate holes on clamp, and this elongate holes is just located at outside the passive impingement position of U-lag side wall.

The method have the benefit that：The present invention passes through to arrange buffer structure on automobile side door lock clamp U-lag opening sidewalls, effectively reduce the noise that latch engagement post is produced with the collision of clamp U-lag opening sidewalls, again by the optimization processing to clamp U-lag open curve, greatly reduce the noise of closing the door of automobile side-door.

Specific embodiment

Embodiment:A kind of clamp 1 reduces noise structure, described clamp 1 is provided with the U-lag 3 being fastened and connected with latch engagement post 2, it is formed with U-lag 3 side wall and be snapped the passive impingement position that engagement post 2 actively clashes into, the active impingement position of convolution active shock engagement post at a high speed after clamp 1 is knocked is formed with U-lag 3 opposite side wall, on described clamp 1, the active impingement position of U-lag 3 is provided with buffer structure 5.

Automobile is at closing time, the engagement post of lock U-lag 3 opening along along clamp 1 slips into realizes engagement fastening in U-lag 3, realization is closed the door, at closing time, latch engagement post 2 actively clashes into U-lag 3 side wall, after latch engagement post 2 clashes into clamp 1, clamp 1 high-speed rotation, the U-lag 3 opposite side wall of clamp 1 actively clashes into latch engagement post 2, buffer structure 5 is arranged on the active impingement position of U-lag 3 opposite side wall, the noise that this time collision produces can be weakened, and then greatly reduces noise of closing the door when clamp 1 actively clashes into because the cushioning effect of U-lag 3 side wall.

Described buffer structure 5 is the elongate holes on clamp 1, and this elongate holes is just located at outside the active impingement position of U-lag 3 opposite side wall.

By clamp 1U shape groove 3 side wall position of collision being designed to the elongate holes of hollow out, when clamp 1 actively clashes into latch engagement post 2, the active impingement position of U-lag 3 side wall can occur small deformation, realize cushioning effect, reduce noise, in addition can also be inner groovy subtracts meat design, or it is to inlay flexible member in elongate holes, can also be with the form setting flexible member such as injection or assembling on the side wall of U-lag 3 opening position of collision, or increase material thickness of covered material etc. herein to realize buffering decrease of noise functions.

On described clamp 1, U-type groove opening is the smooth transition curve structure tangent with U-lag 3 medial surface, by the optimization of profile to U-lag 3 aperture position, it is made tangent with U-lag 3 medial wall to smoothly transit, latch engagement post 2 is enable smoothly to slip in U-lag 3, and reduce the contact area of latch engagement post 2 and clamp 1U shape groove 3 opening position of collision, effectively reduce noise.

On described clamp 1, the passive impingement position of U-lag 3 is provided with buffer unit 4.

Described buffer unit 4 is the elongate holes on clamp 1, and this elongate holes is just located at outside the passive impingement position of U-lag 3 side wall.

Said structure can be applied in the clamps such as car door, boot door 1 structure, realizes the reduction of noise of closing the door.
