Description
Technical field
The present invention relates to a kind of sealing member, particularly a kind of sealing member with sound insulation vibration-damping function.
Background technology
For many years, sealing member is increasing in the industry and the effect of playing of transportation industry, and for example in the Automobile manufacturing process, they play functions such as vibration damping and structure reinforcement, sound insulation usually.These sealing members generally include a kind of expandable material, and expandable material has advantages such as very light weight, adhesive ability is good, acoustically effective is good.This type material is assemblied in the cavity of vehicle body, and bodywork cavity is filled in the back of expanding, and can effectively reduce the noise in the running car, reduces the vibration damping of vehicle body.
How these expandable materials are fixed in the bodywork cavity, and especially big cavity is puzzlement designer's a difficult problem always.Because the cavity size shape in the vehicle body is not quite similar, and has increased this type design of rubber seal difficulty.Prior art is normally passed through injection molding way with thermal expansion material and carrier injection mo(u)lding together, the technology more complicated, and cost of manufacture is high, leak tightness is relatively poor.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art; The invention provides a kind of sealing member with sound insulation damping of vibrations; This sealing member can be used for various industry and transportation industry; As make industries such as automobile, steamer, train and building, furniture, especially at automobile manufacturing field, the sealing part is specially adapted to fill the auto body cavity.
To achieve these goals; The technical scheme that the present invention adopts is following: a kind of sealing member with sound insulation vibration-damping function; Comprise leakproofing material, adaptor union, steady arm; Said leakproofing material has connecting bore and the knock hole that cooperates with adaptor union and steady arm respectively, and leakproofing material passes through the matching and fixing of connecting bore and adaptor union on the sealing position, and through knock hole and cooperating of steady arm being positioned to seal on the position.
Preferably, said leakproofing material is a thermal expansion material, and this thermal expansion material is the thermoset material that has the crosslinked foaming characteristic under the uniform temperature, comprises a kind of polyvinyl and a kind of foaming agent at least.
Preferably, said thermal expansion material can through extrude, mold pressing or the moulding of injection moulding mode.
Preferably, the volume after said thermal expansion material expands is at least 1000% of original volume.
Preferably, said adaptor union comprises and the first of said leakproofing material connecting bore matching and fixing and the second portion that cooperates with hermetic unit; Said steady arm comprises first that cooperates the location with said leakproofing material knock hole and the second portion that cooperates with hermetic unit.
Preferably, the first of said adaptor union and second portion shape are selected from one of following shape: rectangular cylindrical, screwed screw shaped, pitch cone shape.
Preferably, the first of said steady arm and second portion shape are selected from one of following shape: elongated cylindrical, taper shape.
Preferably, said steady arm is a locating dowel pin.
Preferably, said adaptor union is a thermoplastic plastic.
The invention has the beneficial effects as follows: the sealing part had both overcome the difficult point that expandable material is difficult to fix in the cavity; Have again and make things convenient for installation, accurate positioning, advantage that leakproofness is good; Solved the deficiency of prior art, be particularly useful for the bigger position of bodywork cavity and use.

The specific embodiment
Below in conjunction with accompanying drawing a kind of specific embodiment of the present invention is explained.
As shown in Figure 1, the sealing part generally includes with lower component: thermal expansion material 1, adaptor union 2 and locating dowel pin 3.Thermal expansion material 1 surface has two holes 4 at least, in two holes 4 of an insertion thermal expansion material 1 of adaptor union 2 and locating dowel pin 3, forms a whole.
The adaptor union profile profile that the present invention possibly use can have multiple.As shown in Figure 2, adaptor union all has following characteristic: adaptor union 2 has two, and one is inserted thermal expansion material 1, and insert in the hole on the vehicle body panel beating 5 other end.The diameter at adaptor union 2 two is a bit larger tham hole 4 and the hole on the vehicle body panel beating 5 above the thermal expansion material 1, so that fitting tight.Enumerate out 3 adaptor unions among the figure, the shape at its two can be respectively a pitch cone shape, and promptly several bullets connect from beginning to end; Form microscler pitch cone shape, rectangular cylindrical, screwed screw shaped; Only being to present the possible shape of adaptor union, is not that the shape of restriction adaptor union has only these several kinds, and the adaptor union 2 of employing can be thermoplastic plastic, elastic body, thermosetting plastic and their combination material thereof; Adaptor union has two; One is used to connect the auxiliary hole on the vehicle body panel beating, and one is connected with thermal expansion material, prevents that thermal expansion material from coming off.
As shown in Figure 3, the locating dowel pin shape that the present invention possibly use has multiple.But all have following characteristic: locating dowel pin 3 is strip structure, is used for the location, places expandable material mobile, rotational deformation in cavity.One of locating dowel pin 3 is inserted into the hole 4 above the thermal expansion material 1, and the other end also is fixed on the hole of panel beating 5 of vehicle body, and its effect is to prevent thermal expansion material 1 displacement.Enumerate out 3 locating dowel pins among the figure, the shape at its two can be respectively rectangular cylindrical, different rectangular cylindrical of diameter; Conical; Only be to present the possible shape of locating dowel pin above-mentioned comprising, is not that the shape of restriction locating dowel pin has only these several kinds, and locating dowel pin 3 can be that metal, plastics, material such as wooden are processed; Purpose is that thermal expansion material is positioned, and prevents its rotation.
Sealing member with sound insulation vibration-damping function provided by the invention inserts the other end of adaptor union 2 in the hole of panel beating 5 earlier in use, is fixed, and then the other end of locating dowel pin 3 is inserted in the hole of panel beating 5, is located.After assembling was accomplished, thermal expansion material can expanded by heating, and the cavity 6 of auto body has been cut off flowing of air by sealing fully, plays the effect of sound insulation, vibration damping.
Sealing part assembling accomplish the back with car load through the painting dressing automobiles or the workshop that is welded, along with the high temperature (140 ~ 200 ℃) of workshop baking, the thermal expansion material expanded by heating, after expanding or uniform state, the defective of significantly not caving in and big bubble.The more original volume of volume after the expansion enlarges several times (be at least original 1000%, even bigger).
More than an instance of the present invention is specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
