Abstract
The utility model relates to an automobile an automobile cavity sound -insulation sealing part in NVH field. Including plastics cardboard, foam sheet, sheetmetal, plastics cardboard up end is equipped with a plastics buckle, and the terminal surface is equipped with the fixed knot of two plastics and two reference columns respectively before the plastics cardboard, the sheetmetal is irregularly shaped, and on the front -back of sheetmetal, cladding one deck foam sheet is equipped with 1 strip fixing hole, 3 strip electrophoresis through -holes respectively on foam sheet's face respectively, and strip fixing hole level sets up, and 3 strip electrophoresis through -hole vertical separation's setting is in strip fixing hole below, the plastics cardboard has foam sheet's sheetmetal laminating to be in the same place with the cladding to fix the sheetmetal on the plastics cardboard with strip fixing hole's cooperation through fixed knot of two plastics. Can be used to the packing of the great cavity of car body, preparation simple process, simple to operate, the location is accurate, the effect that gives sound insulation is obvious, the expanded material materials are few, and the cost of manufacture is low, use safe and reliable.
Description
Technical field
The utility model relates to a kind of vehicular spare parts, particularly a kind of a kind of automobile cavity sound insulating seal part of auto NVH field.
Background technology
In recent years, the expandable material of sound insulation, vibration damping is increasing in the effect played in auto NVH field, and such as, during galloping, the bypass cavity of vehicle body can produce high velocity air when running at high speed, and brings strong noise and vibration can to passenger and driver.In order to address this problem, various expanded material has been widely used in fills in bypass cavity.What current application was more is vinyl (as EVA) expanded material, and it has the advantages such as very light weight, adhesive ability is good, acoustically effective is good.This kind of material is assemblied in the cavity of vehicle body, fills bodywork cavity after expansion, plays the object of sound insulation, vibration damping.But for the larger cavity of vehicle body, if all fill full, material requested consumption is large, and cost is high, therefore must find new method and be fixed such material.
Summary of the invention
In view of the situation that prior art exists, the utility model, with providing a kind of automobile cavity sound insulating seal part, for the filling of the larger cavity of auto body, greatly saves expanded material consumption, cost is reduced greatly.
The utility model for achieving the above object, the technical scheme adopted is: a kind of automobile cavity sound insulating seal part, it is characterized in that: comprise plastics clamp, foam sheet, sheetmetal, described plastics clamp upper surface is provided with a plastic buckle, and described plastic clip front edge of board face is respectively equipped with two plastics clips and two registration masts;
Described sheetmetal is irregularly shaped, on the front-back of sheetmetal, coated one deck foam sheet respectively, the face of foam sheet is respectively equipped with 1 strip fixed via, 3 strip electrophoresis through holes, strip fixed via is horizontally disposed with, 3 strip electrophoresis through hole perpendicular separations be arranged on below strip fixed via;
Plastics clamp fits together with the sheetmetal being coated with foam sheet, and is fixed on plastics clamp by sheetmetal with coordinating of strip fixed via by two plastics clips.
The utility model has the advantages that, can be used for the filling of the larger cavity of auto body, manufacture craft is simple, easy for installation, accurate positioning, soundproof effect obviously, expanded material materials are few, cost of manufacture is low, and use procedure is safe and reliable.
Accompanying drawing explanation
Fig. 1 is lateral plan of the present utility model;
Fig. 2 is front view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present utility model is described further.
Consult shown in Fig. 1,2, a kind of automobile cavity sound insulating seal part, comprises plastics clamp 1, foam sheet 2, sheetmetal 3.
Be provided with a plastic buckle 1-1 in plastics clamp 1 upper surface, be respectively equipped with two plastics clip 1-2 and two registration mast 1-3 at plastics clamp 1 front end face.
Sheetmetal 3 is irregularly shaped, on the front-back of sheetmetal 3, coated one deck foam sheet 2 respectively, the face of foam sheet 2 is respectively equipped with 1 strip fixed via, 4,3 strip electrophoresis through holes 5, strip fixed via 4 is horizontally disposed with, being arranged on below strip fixed via 4 of 3 strip electrophoresis through hole 5 perpendicular separations.
Plastics clamp 1 and the sheetmetal 3 being coated with foam sheet 2 are fit together, and with coordinating of strip fixed via 4, sheetmetal 3 is fixed on plastics clamp 1 by two plastics clip 1-2.
During use, plastics clamp 1 is fixed to by plastic buckle 1-1 on the auxiliary hole of the sheet metal component in auto body cavity, the effect of two registration mast 1-3 is positioned on sheet metal component by firm for the utility model, thereafter electrophoresis operation is entered, due to sealing member having 3 strip electrophoresis through holes 5, electrophoresis liquid can pass through the seal smoothly.Next carry out high-temperature baking, foam sheet 2 is expanded foamed, fully fills 3 strip electrophoresis through holes 5 and automobile cavity, plays the object intercepting air flowing and reduce noise.
The utility model can according to the shape of auto body cavity, size flexible design.
Plastic buckle 1-1, plastics clip 1-2 are resistant to elevated temperatures nylon material, namely can be used for connection metal sheet and foam sheet, achieve again and are fixed on bodywork cavity sheet metal component by device, solve the problem that expanded material is difficult to fix.
Sheetmetal 3 is steel plate or aluminium sheet, and strip fixed via 4 is used to fixing foam sheet and sheetmetal, and 3 strip electrophoresis through holes 5 are used for making the electrophoresis liquid of electrophoresis operation pass through the seal smoothly.
Foam sheet 2 is the high temperature expandable material that polyvinyls or copolymer interpolation foaming agent, crosslinking agent, extending agent etc. mix.
