It is used for building, automobile industry.For example：CN201310474877.X describes a kind of double layer glass, with two-layer tempering glass
Glass, centre is filled with inert gas or nitrogen, has the advantages that sound insulation is good, sturdy and durable；CN 201520803062.6 is described
A kind of super vacuum glass, is made up of triplex glass, is vacuum layer between first and second layer, is inert gas between second and third layer
Layer, the glass structure has good sound insulation, heat-blocking action；(3) it is sound absorber in the middle of, then by the rigid member of both sides, for example
Aluminium sheet, steel plate etc. sandwich the sandwich sound panel to be formed, and are used for the sound insulation and noise reduction of middle-size and small-size electromechanical equipment, such as air-conditioning
Cabinet-type air conditioner etc..
The usual weight of first, second kind of septum arrangements of the above, thickness are all very big, in the confined space and freight weight limit situation
Under it is very not applicable, although the third structure light weight and thin, soundproof effect is general.
Helium is a kind of inert gas, is formed by most sluggish helium element in nature, is a kind of pole at normal temperatures
Gently colourless, odorless, tasteless monoatomic gas, helium is sufficiently stable, it is impossible to which burning can not be combustion-supporting, safe and reliable.Relatively
For air, helium can play more excellent deadening in medium-high frequency section.
Utility model content
The technical problems to be solved in the utility model is：Based on the problems referred to above, there is provided a kind of helium sound panel.
The utility model solves the technical scheme that its technical problem adopted：A kind of helium sound panel, in being located at
Between helium cladding, be symmetricly set in the upper aluminium sheet and lower aluminum sheet of helium cladding both sides, helium cladding is elastomeric overmold
The tabular gas cell with closing inflation inner chamber that film is surrounded, the inner chamber of helium cladding is full of helium, opens on helium cladding
Several holes through helium cladding both sides are provided with, elastic support, two ends of elastic support are inserted with hole
Portion is bonding with the inwall of upper aluminium sheet, lower aluminum sheet respectively.
Further, the elastomeric overmold film towards aluminium sheet of helium cladding is in rough wavy.
Further, the thickness of upper aluminium sheet and lower aluminum sheet is 1mm, and the thickness of helium cladding is 9.5～10mm.
Further, the thickness of elastomeric overmold film is 0.5mm, and material is rubber.

The beneficial effects of the utility model are：Between the helium cladding that presss from both sides can not only optimize the fire-and explosion-proof of sound panel
Property, and can guarantee that stronger bending resistance compressive property；Can accomplish on the premise of not increasing weight, not thickening, realize sound transmission loss compared with
Significantly lifted, be particularly well-suited to the sound insulation and noise reduction of some middle-size and small-size electromechanical equipment, household electrical appliance etc..
Description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein：1. aluminium sheet is gone up, 2. lower aluminum sheet, 3. helium cladding, 4. elastic support.
Specific embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of helium sound panel as shown in Figure 1, including the helium cladding 3 positioned at centre, is symmetricly set in helium bag
The upper aluminium sheet 1 and lower aluminum sheet 2 of the both sides of body 3 are covered, helium cladding 3 is the plate with closing inflation inner chamber that elastomeric overmold film is surrounded
Shape gas cell, the inner chamber of helium cladding 3 is full of helium, and several are offered on helium cladding 3 through helium cladding two
The hole of side, is inserted with elastic support 4 in hole, two ends of elastic support 4 respectively with upper aluminium sheet 1, lower aluminum sheet 2
Inwall bonding.Four sides of hole are sealings, will not be overflowed after full of nitrogen.
The elastomeric overmold film towards aluminium sheet of helium cladding 3 is in rough wavy.Wavelike structure be in order to
Sound wave is dissipated in sound wave incident, more preferable sound insulation effect can be played.
The thickness of upper aluminium sheet 1 and lower aluminum sheet 2 is 1mm, and the thickness of helium cladding 3 is 9.5～10mm.
