Abstract
The utility model relates to an automobile soundproof sealing device, which comprise plastic fasteners, a front metal sheet, a rear metal sheet and a foaming sheet. At least two superposed through holes are arranged on sides of the front metal sheet, the foaming sheet and the rear metal sheet, at least two through holes are arranged on a projected sheet integrally connected with the rear metal sheet, and the foaming sheet is integrally fixedly arranged between the front metal sheet and the rear metal sheet through the plastic fasteners. The automobile soundproof sealing device has the advantages that the device is simple in manufacturing process, convenient in mounting, accurate in positioning, evident in soundproof effect, low in use of foaming materials and safe and reliable in use, and cost is saved.
Description
Technical field
The utility model relates to the auto sound sealing arrangement in a kind of automobile NVH field.
Background technology
In recent years, the expandable material of sound insulation, vibration damping is increasing in the effect of playing in automobile NVH field, and for example during galloping, the bypass cavity of vehicle body can produce high velocity air when running at high speed, and bring strong noise and vibration can for passenger and driver.In order to address this problem, various expanded materials have been widely used in fills in the bypass cavity.What application was more at present is vinyl (as EVA) expanded material, and it has advantages such as very light weight, adhesive ability is good, acoustically effective is good.This class material is assemblied in the cavity of vehicle body, and bodywork cavity is filled in the back of expanding, and plays the purpose of sound insulation, vibration damping.But for the big cavity of vehicle body, expire if all fill, the material requested consumption is big, and therefore the cost height must be sought new method such material is fixed.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of auto sound sealing arrangement.This device can be according to shape, the size flexible design of auto body cavity.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of auto sound sealing arrangement, it is characterized in that: comprise plastic buckle, preceding sheetmetal, back sheetmetal, foam sheet, before described, be respectively equipped with at least two through holes that overlap on the face of sheetmetal, foam sheet, back sheetmetal, on the tabs that is connected as a single entity with the back sheetmetal, be provided with at least two through holes; Interfix by plastic buckle between sheetmetal and the back sheetmetal before described foam sheet is arranged on and be one.
Characteristics of the present utility model are: this device manufacture craft is simple, easy for installation, accurate positioning,, soundproof effect obviously, the expanded material materials are few, save cost, use is safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the auto sound sealing arrangement comprises plastic buckle 1, preceding sheetmetal 2, back sheetmetal 3, foam sheet 4.
On the face of preceding sheetmetal 2, foam sheet 4, back sheetmetal 3, be equipped with at least two through holes that overlap respectively, on the tabs 3-1 that is connected as a single entity with back sheetmetal 3, be equipped with at least two through hole 3-2.Before foam sheet 4 is placed between sheetmetal 2 and the back sheetmetal 3, and insert by at least two plastic buckles 1 be fixed in the through hole that coincides as a whole.In this when device, be installed, earlier with in the auto body cavity sheet metal component on punch, plastic buckle 1 is fixed together the hole on this device and the sheet metal component by several through holes 3-2 on the sheetmetal 3 of back.Behind this device assembling back high-temperature baking with later process, foam sheet is expanded foamed, fully fills a certain cross-sectional plane of bodywork cavity, intercepts the mobile purpose that reaches sound insulation and noise reduction of high velocity air thereby play.
Foam sheet is that polyvinyls or copolymer add the high temperature expandable material that foaming agent, crosslinking agent, extending agent etc. mix, add and to be molded into sheet material by mold pressing, mode such as extrude man-hour, cut into required form again and beat two or more holes, its position overlaps with sheetmetal.
Claims (3)
