The attached plate aluminium sheet of outer layer, sound insulation glue adhesive linkage, the mainboard steel plate and attached plate aluminium are provided between attached plate aluminium sheet and mainboard steel plate
Welding electrode is respectively equipped with plate, opposed welding electrode acts on mainboard steel plate and attached plate aluminium sheet forms welding point, and it connects
Conjunction face forms diffusion layer.
Further, above-mentioned lightweight sound insulation board component, wherein, the welding electrode is installed on robot arm.
Further, above-mentioned lightweight sound insulation board component, wherein, the sound insulation glue adhesive linkage is acrylic acid glue
Layer.
Further, above-mentioned lightweight sound insulation board component, wherein, the thickness of the mainboard steel plate is 1.0~3.0 millis
Rice.
Further, above-mentioned lightweight sound insulation board component, wherein, the thickness of the attached plate aluminium sheet is 0.2~0.8 milli
Rice.
The utility model has the advantages of notable and beneficial effect compared with prior art, embodies in the following areas：
Lightweight sound insulation plate component structure of the present utility model is simple, and lightweight, composite board sound transmission loss is big, plastic deformation
It is good, available for multiple positions on car.Have the characteristics that sound insulation capabilities are strong, unit area is small, light weight, be easy to shaping, meet
The trend of vehicle lightweight development.
Brief description of the drawings
Fig. 1：Structural representation of the present utility model.
Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing
Illustrate specific embodiment.
As shown in figure 1, lightweight sound insulation board component, comprising the mainboard steel plate 1 for automobile-used plate component structure substrate and
Positioned at the attached plate aluminium sheet 2 of outer layer, the thickness of mainboard steel plate 1 is 1.0~3.0 millimeters, and the thickness of attached plate aluminium sheet 2 is 0.2~0.8 milli
Rice；Sound insulation glue adhesive linkage 3 is provided between attached plate aluminium sheet 2 and mainboard steel plate 1, sound insulation glue adhesive linkage 3 is acrylate glue water layer,
Mainboard steel plate 1 is provided with welding electrode 5, and attached plate aluminium sheet 2 is provided with welding electrode 4, and opposed welding electrode acts on mainboard steel
Plate 1 and attached plate aluminium sheet 2 form welding point 6, and its composition surface forms diffusion layer.
Two welding electrodes are respectively arranged on robot arm so that electrode can be programmed to form number in precalculated position
Individual welding point, and another can be moved to from a predetermined welding point position rapidly, realize automated production.
Mainboard steel plate 1 is used as the structural substrate of automobile-used board component, and can be stamped, stretch, shearing or being shaped with other
Method is formed as required shape.Mainboard steel plate 1 is typically larger than attached plate aluminium sheet 2, rather than using complete sound insulation laminate and
It can be made up of any amount of suitable material, attached plate aluminium sheet material is aluminium, can effectively mitigate weight.
The diffusion welding (DW) that the welding electrode 5 of welding electrode 4 and second is acted on, at a certain temperature, by steel and surface of aluminum plate
Contact diffusion, very thin diffusion layer being produced on composition surface, the size and shape for welding opening may depend on a number of factors, including with
In the size for the welding equipment for forming welding point.In general, the size of each welding opening is small as far as possible, to adapt to
The specific weld equipment used, but maximize the amount of the acoustic material in acoustic sensing region.The welding of any several amount and type connects
Head may be formed in each welding opening.
Lightweight sound insulation plate component structure of the present utility model is simple, and lightweight, composite board sound transmission loss is big, plastic deformation
It is good, available for multiple positions on car.Have the characteristics that sound insulation capabilities are strong, unit area is small, light weight, be easy to shaping, meet
The trend of vehicle lightweight development.
It should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this practicality
New interest field；Description more than simultaneously, should can understand and implement for the special personage of correlative technology field, therefore its
It should be included in claim without departing from the equivalent change or modification completed under the spirit disclosed in the utility model
In.
