Abstract
The utility model relates to a vibration isolator, which is arranged in the cavity of the car body in the central section of the top-pillar of a saloon car, comprising a heat-resistant hard frame and a foaming body which can foam and inflate after being heated. The frame comprises a panel and two elastic support legs connected with one side of the panel; the flat shape of the panel is similar to the section shape of the cavity at the corresponding position in the central section of the top-pillar of the saloon car; the panel is provided with a gap and a channel; the gap is used to flow the liquid for pickling, neuralizaition, parkerising or purification. The foaming body is embedded on the panel. After the utility model is foamed and inflated when arranged in the cavity of the car body at the central section of the top-pillar, the utility model can paste tightly as a whole with the car body plates of the position, and effectively block the channel of the cavity at the position. Therefore, the utility model has the advanags that the vibration isolation, sound insulation, vibration damping and noise reducing in the cockpits of the saloon car can be further improved and increased.
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 middle part.
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, to seal the car body cavity vibration isolating pad that is arranged on car fore-set middle part that bodywork cavity can improve interior vibration of car passenger cabin and noise effectively thereby provide a kind of.
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 middle part, be provided with brace panel in the bodywork cavity at described fore-set middle part, 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 two flexible feets of panel one side, and the aspect of panel is similar with the cross sectional shape of the cavity of car fore-set middle part corresponding site and be provided with the confession pickling, neutralization, phosphatization, the breach and the passage 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 middle part, 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 at vibration isolating pad and fore-set middle part closely is bonded to one, can intercept the cavity passage at this place effectively, reach totally-enclosed, thereby vibration source and noise that original fore-set center 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.

Fig. 1 is the perspective view that the utility model is arranged on the car body cavity vibration isolating pad at car fore-set middle part.
Fig. 2 is the structural representation of facing of the present utility model;
Fig. 3 is a side-looking structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, cooperate referring to Fig. 2, Fig. 3, the utility model is arranged on the car body cavity vibration isolating pad at car fore-set middle part, comprises skeleton 1 and foaming body 2, and skeleton 1 is made by heat-resisting high-intensity nylon 6-6, and foaming body 2 can foaming and intumescing after heating.In the bodywork cavity at the related car fore-set middle part of the utility model, be provided with brace panel.Skeleton 1 in the utility model comprises a panel 11 and is connected two flexible feets 12,13 of panel one side, the cross sectional shape of the cavity of the aspect of panel 11 and car fore-set middle part corresponding site is similar and be provided with breach 111 and passage 112 for pickling, neutralization, phosphatization, purification of liquid circulation, on panel, be provided with the step that is used for the setting-in foaming body, and on step, be provided with a plurality of posts 14 that are used for fixing foaming body.Foaming body is inlaid in locatees on the step of panel and by a plurality of post and fixes.Also be outward extended with at least one in the side of foaming body and can contact the projection 21 that links to each other with vehicle body.
The car body cavity vibration isolating pad that the utility model is arranged on car fore-set middle part can be separately positioned on the corresponding site at left and right fore-set middle part.
