Description
Technical field
The utility model relates to a kind of automobile manufacture accessories, and it is swollen to be particularly to a kind of sound insulation for vehicle side cavity
Swollen blob of viscose.
Background technique
For automobile manufacture, NVH(noise, vibration, comfort) performance be automobile major criterion.The NVH of vehicle
Performance can make automobile in high-speed cruising well, mitigate high-speed flow to rider and driver's bring noise and vibration.In recent years
Come, with the continuous improvement and progress of automobile manufacturing process, sealing, sound insulation, vibration damping expanding material played in auto NVH field
Effect it is increasing, in order to preferably solve the high-speed flow that bodywork cavity is generated in high-speed cruising, various foamed materials
It has been widely used in filling body of a motor car bypass cavity, some foamed materials are too close apart from Metal Sheets for Body-manufacturing, in metal plate
Gold solder is easy to cause foamed material high temperature deformation even to burn during connecing, it is therefore desirable to by foamed material and sheet metal component interval
A certain distance prevents it from influencing welding, some foamed materials are also easy to fall off after foaming, and sealing effect is caused to decline.
Summary of the invention
The purpose of this utility model is to provide one kind aiming at the problem that existing foamed material influences welding, is easy to fall off
Assembling process is simple, accurate positioning, in assembling process, it is not easy to which the sound insulation for causing foamed material high temperature deformation even to be burnt is swollen
Swollen blob of viscose structure.
To achieve the above object, used technical solution is the utility model: it is a kind of for vehicle side cavity every
Sound expansion slab rubber, it is characterised in that: the sound insulation expansion slab rubber is made of plastic buckle, foam sheet, galvanized steel plain sheet；
The plastic buckle forms an overall structure by plastic card sets and plastic staple bolt, and the diameter of plastic card sets is greater than modeling
Expect the diameter of bail；
The galvanized steel plain sheet is rectangle, and several circular holes are arranged in galvanized steel plate face；
Squeeze one layer of foam sheet respectively on two faces of galvanized steel plain sheet, two layers of foam sheet by with galvanized steel plain sheet number
The cooperation of a circular hole and galvanized steel plain sheet constitute an integral slab, are spaced in two circular holes being provided on integral slab and are respectively set one
A plastic buckle.
The utility model has the advantages that: the structure design of bail be fixed to foam sheet can accurately at bodywork cavity,
Solve the problems, such as that foam sheet is caducous.
The outer diameter of plastic card sets is greater than the structure design of fabrication hole on plates of automobile, in assembling process, makes foamed material
It is spaced a certain distance with sheet metal component, foam sheet and sheet metal component are not directly contacted with, and during metal plate welding, are avoided
The generation for the case where foamed material high temperature deformation is even burnt.
Galvanized steel plain sheet is located among foamed material as skeleton, keeps the foam sheet of upper and lower surface expandable, sealing effect
Fruit is good, plays barrier high-speed flow, has achieved the effect that sound insulation and noise reduction.
Assembly manipulation process is simple, accurate positioning, safe and reliable.
Detailed description of the invention:
Fig. 1 is the main view of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is the schematic diagram of the utility model galvanized steel plain sheet.
Specific embodiment
It is described further below in conjunction with structure of the attached drawing to the utility model.
Refering to fig. 1, Fig. 2 and Fig. 3, a kind of sound insulation expansion slab rubber for vehicle side cavity, the sound insulation expansion slab rubber by
Plastic buckle 1, foam sheet 2, galvanized steel plain sheet 3 form.
Plastic buckle 1 forms an overall structure, the diameter of plastic card sets 1-1 by plastic card sets 1-1 and plastic staple bolt 1-2
Greater than the diameter of plastic staple bolt 1-2.
Galvanized steel plain sheet 3 is rectangle, and several circular hole 3-1 are arranged on 3 face of galvanized steel plain sheet.
Squeeze one layer of foam sheet 2 respectively on two faces of galvanized steel plain sheet 3, two layers of foam sheet 2 by with galvanized steel
The cooperation of the several circular hole 3-1 of plate 3 and galvanized steel plain sheet 3 constitute an integral slab, are spaced in two circular holes being provided on integral slab
A plastic buckle 1 is respectively set.
The technique that sound insulation expansion slab rubber is fixed on automobile body sheet metal part by bail 1-2 when use by plastic buckle 1
Kong Shang, with the high-temperature baking of later process after assembly, the foam sheet 2 of sound insulation expansion slab rubber starts to expand, and is sufficient filling with automobile
The cross section of side wall cavity plays barrier high-speed flow, achievees the effect that sound insulation and noise reduction.
Bail 1-2 is nylon 6 resistant to high temperature or nylon66 fiber material, to connect bodywork cavity fabrication hole and foam sheet,
Foam sheet is accurately fixed at bodywork cavity, solves the problems, such as that foam sheet is caducous.
Plastic card sets 1-1 is nylon 6 resistant to high temperature or nylon66 fiber material, and outer diameter is greater than the fabrication hole on plates of automobile,
Purpose is for avoiding foam sheet and sheet metal component from directly contacting.
Foam sheet 2 is expandable polyolefine material, or is polyvinyls or copolymer, and addition foaming agent is handed over
The high-temperature expansion foamed material that connection agent etc. mixes, when processing, are formed by way of being coextruded with galvanized steel plain sheet, become one
A entirety is punched into different shapes further according to body of a motor car cavity shape.
3 material of galvanized steel plain sheet is galvanized steel, it is therefore an objective to provide the structural support for foam sheet 2, while surface be provided with it is several
Circular hole 3-1 respectively has one layer of foam sheet 2 up and down, what two layers of foam sheet 2 can not be split by several circular hole 3-1 formation one
It is whole.
