Description
Technical field
The utility model relates to a kind of auto parts and components, relates in particular to a kind of car body cavity vibration isolating pad that is arranged on car CD post top.
Background technology
Along with developing of automobile industry, people are more and more higher to the requirement of " safety, traveling comfort, the feature of environmental protection " of car, and the standard-required to " sound insulation, vibration isolation, anticorrosion, noise control " in the car passenger cabin also constantly promotes.The AE personnel have located to do the technology upgrading of sound insulation vibration isolation to enclosure sound heat insulating mattress, car internal sound insulation, vibration isolation carpet, vehicle body sticking glass, car roof etc. before ride-control, the front and back in car at present, make vibration and noise in the car passenger cabin obtain the actv. improvement.But the cavity passage in the body structure also can vibrative noise, and this technical matters is not well solved all the time.
The manufacturing process of vehicle body is, earlier with sheet metal by the die stamping moulding after, form by Automobile Plate metal seam such as inner panel, brace panel and outside plates.Therefore generally in the middle of inner panel and brace panel and outside plate, be bound to form necessary gap and space, be included in zones such as body platform beam, A, B, C, D column, rear wheel cover, ceiling, upper/lower terminal dash shield, ceiling, fender upper end, back and four door-plates and all can form cavity.Particularly Reinforcement A, B, C, D column and two bottom sides longeron have all formed the column structure spare of hollow.The hollow structure of these column pieces and longeron has guaranteed the intensity and the rigidity of body structure effectively, so the cavity state in the body structure is must have.But the cavity of this body structure has also formed the specific channel that transmits ambient noise and vibration.The metal sheet of the ceiling of vehicle body, the isometric form of longeron can form sound because of distortion, the vibration of structure when crossing the road ditch; In the high vehicle speeds motion, can form the sympathetic response sound to vehicle body because of extraneous blast, windage again; The pavement of road sandstone also can on the go to the vehicle body sound that impacts; The resonance frequency that produces in the motion can form the vibration and the sound to vehicle-body outer panel.These noises and vibration all can be transmitted in the cavity between the inside and outside plate of vehicle body fast, thereby noise and transfer of vibration are arrived in the passenger cabin of car, influence driver and conductor's traveling comfort.
Summary of the invention
The purpose of this utility model is exactly in order to solve the problem that above-mentioned prior art exists, thereby provides a kind of bodywork cavity that can seal can improve the vibration in the car passenger cabin and the car body cavity vibration isolating pad that is arranged on car CD post top of noise effectively.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of car body cavity vibration isolating pad that is arranged on car CD post top, in the bodywork cavity on car CD post top, be provided with brace panel, be characterized in, described car body cavity vibration isolating pad is made up of two vibration isolation pieces that can be separately positioned on brace panel both sides in the vehicle body, two vibration isolation pieces all are the integral slab shape framing members that is constituted by foaming body that can foaming and intumescing after heat-resisting hard skeleton and the heating, connect by at least one cover attaching parts between two vibration isolation pieces; One of them vibration isolation piece have to vehicle body in the similar aspect of cavity cross section of brace panel one side, and leave gap for the foaming body foaming and intumescing with respect to the periphery of respective cross-section, another vibration isolation piece have to vehicle body in the similar aspect of cavity cross section of brace panel opposite side, and leave gap for the foaming body foaming and intumescing with respect to the periphery of respective cross-section; Foaming body in the two vibration isolation pieces is respectively attached on the skeleton of two vibration isolation pieces and have at the thickness that can fill up the gap between vibration isolation piece and inside and outside plate of vehicle body and the brace panel behind the foaming and intumescing.
Attaching parts between described two vibration isolation pieces comprises a buckle-type attaching parts, and this buckle-type attaching parts is made up of elastic fastening hook that is arranged on vibration isolation piece both sides and the corresponding fixture block that is arranged on another vibration isolation piece both sides.
Attaching parts between described two vibration isolation pieces also comprises a plug-in type positioning link, and this plug-in type positioning link is formed with the corresponding patchhole that is arranged on another vibration isolation piece by being arranged on a contact pin on the vibration isolation piece.
Be provided with in side of its contiguous vehicle body respectively on the foaming body of described two vibration isolation pieces and contact the locating convex block that links to each other with vehicle body, or also be provided with and contact the locating convex block that links to each other with brace panel in side of its contiguous brace panel.
In in conjunction with the Automobile manufacturing technological process, rationally reach desirable task program, car body cavity vibration isolating pad of the present utility model is arranged in the bodywork cavity on car CD post top, 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 160～190 ℃ of high temperature and certain hour, foaming body 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 on CD post top in the former vehicle body effectively, reach totally-enclosed, thereby vibration source and noise that former cause CD post top is imported into through bodywork cavity intercept, and reach the purpose of further improving the interior vibration isolation of car passenger cabin, sound insulation, vibration damping, noise reduction.Simultaneously, after car body cavity vibration isolating pad foamed in bodywork cavity and bonds, the intensity of also further having reinforced vehicle body had all played optimization function to body structure and vehicle body crash-protective characteristics, makes the traveling comfort of car and safety obtain important lifting.
