In order to achieve the above object, the utility model has adopted following technical scheme: a kind of improved type compound type car body cavity vibration isolating pad, form by two vibration isolation pieces that can be separately positioned on brace panel both sides in the vehicle body, two vibration isolation pieces all are integral slab shape framing members, one of them vibration isolation piece is made of foaming body, its have to vehicle body in the similar aspect of cavity cross section of brace panel one side, and leave required fluid passage gap in several roads technology in early stage that before stoving of the paint technology, must carry out for the gap of foaming body foaming and intumescing with for body in white with respect to the periphery of respective cross-section; Another vibration isolation piece is constituted by basic skeleton and the foaming body that is enclosed in around the basic skeleton, its have to vehicle body in the similar aspect of cavity cross section of brace panel opposite side, and leave required fluid passage gap in several roads technology in early stage that before stoving of the paint technology, must carry out for the gap of foaming body foaming and intumescing with for body in white with respect to the periphery of respective cross-section; Foaming body in the described two vibration isolation pieces all has at the thickness that can fill up the gap between vibration isolation piece and vehicle body and the brace panel behind the foaming and intumescing.
The periphery of the basic skeleton in the described vibration isolation piece that is constituted by basic skeleton and foaming body is provided with groove, and foaming body is inlaid in this groove.
The periphery of the basic skeleton in the described vibration isolation piece that is constituted by basic skeleton and foaming body is provided with step, and foaming body is inlaid on this step.
One end of the basic skeleton in the described vibration isolation piece that is constituted by basic skeleton and foaming body is provided with and is used for and connecting element that body contact is fixing.
Described connecting element is the buckle-type connecting element.
Be provided with in side of its contiguous brace panel respectively on the foaming body of described two vibration isolation pieces and contact the locating convex block that links to each other with brace panel, and be provided with in side of its contiguous vehicle body and contact the locating convex block that links to each other with vehicle body.
The described locating convex block that is arranged on contiguous brace panel one side of foaming body of two vibration isolation pieces is provided with in pairs.
In in conjunction with the Automobile manufacturing technological process, rationally reach desirable task program, a plurality of the utility model improved type compound type car body cavity vibration isolating pads are arranged among the appropriate location that must intercept in the bodywork cavity, by the time body in white through pickling, neutralization, purifying, phosphatization, enters in the stoving of the paint stove behind first road paint again and toasts.In stove behind 170～190 ℃ of high temperature and certain hour, body in the improved type compound type car body cavity vibration isolating pad is finished the foaming bonding, vibration isolating pad and the inside and outside plate of body in white and brace panel closely are bonded to one, can intercept the cavity passage in the relevant position in the former vehicle body effectively, reach totally-enclosed, thereby vibration source and the noise locating to import into through bodywork cavity through floor bearer, rear wheel cover, ceiling, dash shield, door-plate etc. are originally intercepted, reach the purpose of further improving the interior vibration isolation of car passenger cabin, sound insulation, vibration damping, noise reduction.Simultaneously, improved type compound type car body cavity vibration isolating pad foams in bodywork cavity after the bonding, also further reinforced the intensity of vehicle body, body structure and vehicle body crash-protective characteristics have all been played optimization function, made the traveling comfort of car and safety obtain important lifting.
