Abstract
The utility model relates to an auto part, a sealed expansion glue piece of using of car cavity in an in particular to car NVH field. Including metal sheet, foam sheet, metal sheet one end is the metal clip, and the other end is the face, is equipped with two metal buckles on the metal sheet face, foam sheet is irregularly shaped, is equipped with two fixed orificess and an electrophoresis hole on foam sheet's face, foam sheet fixes on the metal sheet face through the cooperation of two metal buckles of two fixed orificess and metal sheet. The advantage is: can be used to the packing of the great cavity of car body, preparation simple process, assembling process are simple, 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 sealing expansion film 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 sealing expansion film, 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 sealing expansion film, is characterized in that: comprise metal sheet, foam sheet, and described metal sheet one end is metal clip, the other end is plate face, and metal sheet plate face is provided with two metal buckles; The face of described foam sheet is provided with two fixed orifices and an electrophoresis hole; Foam sheet is fixed on metal sheet plate face by coordinating of two fixed orifices and metal sheet two metal buckles.
The utility model has the advantages that: the filling that can be used for the larger cavity of auto body, manufacture craft be simple, fitting process 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 the front view of the utility model foam sheet.
Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present utility model is described further.
As shown in Figure 1, 2, a kind of automobile cavity sealing expansion film, comprises metal sheet 1, foam sheet 2.
Metal sheet 1 one end is metal clip 1-1, and the other end is plate face, and metal sheet 1 plate face is provided with two metal buckle 1-2.
Foam sheet 2 is irregularly shaped, and the face of foam sheet 2 is provided with two fixed orifice 2-1 and electrophoresis hole 2-2.
Foam sheet 2 was fixed on metal sheet 1 plate face by coordinating of two fixed orifice 2-1 and metal sheet 1 two metal buckle 1-2.
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.
During use, snap on the panel beating in auto body cavity by the metal clip 1-1 of metal sheet 1, because metal clip 1-1 is flexible, therefore fixation, can not come off.Through the high-temperature baking of later process, foam sheet 2 is expanded foamed, fully fills up a certain cross-sectional plane of bodywork cavity, plays and intercepts high velocity air flowing, thus reach the object of sound insulation and noise reduction.
