Abstract
The utility model relates to a car body cavity vibration isolating pad arranged at the rear part of a car top column, and comprises a heat resistant rigid framework and a foaming body which can foam and expand after being heated. The framework comprises a panel and three elastic supporting legs connected on one side of the panel, the plane shape of the panel is similar to the sectional plane shape of the cavity at the corresponding part of the car top column rear part, and an inner hole for acid cleaning, neutralizing, coslettizing and depurate liquid flowing is arranged; the foaming body is embedded on the panel. After the utility model pre-arranged in the car body cavity at the rear part of the top column foams and expands, the utility model can be cohered closely with the car body plate and a reinforcing plate into a whole, the cavity channel is separated effectively, therefore the purpose of further improving and advancing the vibration insulation, the sound insulation, the vibration damping and the noise reduction in the car body cabinet is achieved.
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 fore-set rear portion.
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 ride-control, sound-heat insulated cushion, car internal sound insulation, vibration isolation carpet, vehicle body sticking glass, car roof etc. 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 produce the noise with transmitting vibrations, 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 fore-set rear portion 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 fore-set rear portion, be provided with brace panel in the bodywork cavity at described fore-set rear portion, described car body cavity vibration isolating pad comprise can foaming and intumescing after heat-resisting hard skeleton and the heating foaming body, described skeleton comprises a panel and is connected three flexible feets of panel one side, and the aspect of panel is similar to the cross sectional shape of the cavity of car fore-set rear portion corresponding site and be provided with the confession pickling, neutralization, phosphatization, the breach and the endoporus of purification of liquid circulation; Described foaming body is inlaid on the panel.
Described panel is provided with the step that is used for the setting-in foaming body, and is provided with a plurality of posts that are used for fixing foaming body on step.
The side of described foaming body also is outward extended with at least one can contact the projection that links to each other with vehicle body.
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 at car fore-set rear portion, 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, the car body panel and the brace panel at vibration isolating pad and fore-set rear portion closely are bonded to one, can intercept the cavity passage at this place effectively, reach totally-enclosed, thereby vibration source and noise that place, original fore-set rear portion 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.
