Abstract
The utility model relates to a car body cavity vibration isolating pad arranged at the middle part of a car A column, and comprises a heat resistant rigid framework and a foaming body which can foam and expand after being heated. The framework is door-shaped in general, and the framework comprises an upper horizontal bar and two vertical bars which can be elastically deformed for fixing and are connected under the horizontal bar, and the upper surface shape of the horizontal bar is similar to the sectional plane shape of the cavity of the corresponding middle part of the car A column. The foaming body is arranged on the upper surface of the horizontal bar, and the foaming body leaves a space for the foaming body foaming and expanding relative to the corresponding section; the foaming body has a thickness for filling in the space between the vibration isolating pad and the car body after the foaming body foams and expands. After the car body cavity pre-arranged in the middle part of the A column foams and expands, the utility model can be cohered closely with the car body plate into a whole, and the cavity channel at the position 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 the A pole of car 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 the A pole of car 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 the A pole of car middle part, comprise can foaming and intumescing after heat-resisting hard skeleton and the heating foaming body, described skeleton is " ∏ " font on the whole, above comprising " horizontal stroke " and be connected the elastically deformable of " horizontal stroke " downside, fixing " two perpendicular " of usefulness, the upper surface shape of " horizontal stroke " is similar to the cross sectional shape of the cavity of A pole of car middle part corresponding site, and described foaming body is arranged on the upper surface of " horizontal stroke " and leaves the gap of confession foaming body foaming and intumescing with respect to respective cross-section; Foaming body has at the thickness that can fill up the gap between vibration isolating pad and the vehicle body behind the foaming and intumescing.
The upper surface of " horizontal stroke " of described " ∏ " font skeleton has extended upward at least two radius stays, and described foaming body is connected on this radius stay.
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 A pole of car 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 A post 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 A post 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.
