Abstract
The utility model relates to an auto part, a automotive sealing noise insulation in an in particular to car NVH field. Including plastics cardboard, foam sheet, sheetmetal, plastics cardboard up end is equipped with 1 or a plurality of plastics buckle, and the terminal surface is equipped with fixed knot of several plastics and several reference column respectively before the plastics cardboard, foam sheet and sheetmetal are irregularly shaped sheet, on the face of foam sheet and sheetmetal, and corresponding several fixed orifices, at least one electrophoresis hole of being equipped with, plastics cardboard, sheetmetal and foam sheet laminate in proper order and are in the same place to fix sheetmetal and foam sheet on the plastics cardboard with the cooperation of several fixed orifices through fixed knot of several plastics. Characteristics are: 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 automobile sealed sound arrester of one 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 structure 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 sealed sound arrester, 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 sealed sound arrester, it is characterized in that: comprise plastics clamp, foam sheet, sheetmetal, described plastics clamp upper surface is provided with one or more plastic buckles, and described plastic clip front edge of board face is respectively equipped with several plastics clip and several registration mast; Described foam sheet and sheetmetal are erose sheet material, and on the face of foam sheet and sheetmetal, correspondence is provided with several fixed orifice, at least one electrophoresis hole; Described plastics clamp, sheetmetal and foam sheet fit together successively, and sheetmetal and foam sheet are fixed on plastics clamp with coordinating of several fixed orifice by several plastics clip.
Feature of the present utility model is: the filling that can be used for 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 sealed sound arrester, comprise plastics clamp 1, foam sheet 2, sheetmetal 3.
Be provided with one or more plastic buckles 1-1 in plastics clamp 1 upper surface, be respectively equipped with several plastics clip 1-2 and several registration mast 1-3 at plastics clamp 1 front end face.
Foam sheet 2 and sheetmetal 3 are erose sheet material, and on the face of foam sheet 2 and sheetmetal 3, correspondence is provided with several fixed orifice 4, electrophoresis hole 5.
Several plastics clip 1-2 is 4; Several registration mast 1-3 is 4, and several fixed orifice 4 is 4.
Plastics clamp 1, sheetmetal 3 and foam sheet 2 are fit together successively, and with coordinating of several fixed orifice 4, sheetmetal 3 and foam sheet 2 is fixed on plastics clamp 1 by several plastics clip 1-2.
During use, plastics clamp 1 is inserted in the auxiliary hole on automobile cavity sheet metal component by two plastic buckle 1-1, the effect of several registration mast 1-3 is positioned on sheet metal component by firm for the utility model, after the high-temperature baking of later process, foam sheet 2 is expanded foamed, the a certain cross-sectional plane of abundant filling auto body cavity, plays and intercepts high velocity air flowing, thus reach the object of sound insulation and noise reduction.
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 the aperture of several fixed orifice 4 is slightly less than the diameter of plastics clip 1-2, and object is used to fixing foam sheet 2, and the aperture in electrophoresis hole 5 is comparatively large, the row's of being used for electrophoresis liquid.
Foam sheet 2 is the high temperature expandable material that polyvinyls or copolymer add foaming agent, crosslinking agent, extending agent etc. and mix, and adds and can be molded into sheet material, then be cut into required form by mold pressing, the mode such as to extrude man-hour.
