Description
Technical field
The utility model relates to a kind of Automobile manufacturing accessory, particularly a kind of sealed expansion film for auto body cavity.
Background technology
For Automobile manufacturing, NVH(noise, vibration, traveling comfort) performance is the major criterion of automobile.The NVH performance of car load can make well automobile in high-speed cruising, alleviates noise and vibration that high velocity air brings to rider and driver.In recent years, along with improving constantly and progress of automobile manufacturing process, the effect that the expanding material of sealing, sound insulation, vibration damping plays in auto NVH field is increasing, in order to better solve the high velocity air that bodywork cavity produces when high-speed cruising, various expanding material, technique have been widely used in auto body cavity, but these expanding materials are difficult to fix, and often come off and lose efficacy, also have intumescent material swells insufficient height, the phenomenon of full bodywork cavity can not be filled.Therefore how effectively to fix and to fill auto body cavity completely, becoming a puzzlement automobile design developer's difficult problem.
Summary of the invention
In view of the situation of prior art, the purpose of this utility model there is provided a kind of easily fixing sealed expansion film for auto body cavity that also charging efficiency is high.
For achieving the above object, the technical scheme adopted is the utility model: a kind of sealed expansion film for auto body cavity, is characterized in that: comprise plastic buckle, sheetmetal, Acrylic Foam Tape and expanding material; Described expanding material is plates, between sheetmetal and expanding material, be provided with Acrylic Foam Tape, sheetmetal and expanding material unilateral on be at least provided with a corresponding through hole, plastic buckle snaps in through-holes.
The utility model has the advantages that: assembly manipulation process simply, is easily fixed, accurate positioning, difficult drop-off, high to the charging efficiency of bodywork cavity, can fully fill auto body cavity, thus reach the effect improving noise.Cost of manufacture is low, and use procedure is safe and effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, plastic buckle; 2, sheetmetal; 3, Acrylic Foam Tape; 4, expanding material; 4-1, through hole.
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, a kind of sealed expansion film for auto body cavity, comprise plastic buckle 1, sheetmetal 2, Acrylic Foam Tape 3 and expanding material (4).
Expanding material 4 is plates, sheetmetal 2 and expanding material 4 is bonded together by Acrylic Foam Tape 3, and the sheetmetal 2 after bonding and the surface of expanding material 4 at least have a corresponding through hole 4-1, plastic buckle 1 is entrapped in through hole 4-1.
During use, plastic buckle 1 buckle on sealed expansion film is fixed in the auxiliary hole of auto body cavity, through the high-temperature baking technique of subsequent handling after this device has assembled, expanding material 4 is by heat foamable, well can fill up cavity, play and intercept air flowing and reduce the effect of noise, the expansion film effectively solved in existing automobile is fixed loosely, the problem of easy sagging.
The size of sealed expansion film can be determined by the shape of bodywork cavity post, size flexible design.
Above-mentioned plastic buckle 1 is nylon66 fiber material, in order to connect bodywork cavity auxiliary hole and sealed expansion film, solves the caducous problem of sealed expansion film.
Above-mentioned sheetmetal 2 material is steel or aluminium, and be connected by Acrylic Foam Tape 3 with expanding material 4, object is in order to provide the structural support, the sagging phenomenon after stoping expanding material 4 to be heated.
Above-mentioned expanding material 4 is the high-temperature expansion expanded material that polyvinyls or copolymer interpolation foaming agent, crosslinking agent, thixotropic compound etc. mix.Add man-hour by extruding, the mode slabbing body such as calendering, then be cut into different shapes according to auto body cavity structure.
Claims (4)
