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 front frame 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 front frame top, be provided with the polylith brace panel in the bodywork cavity on described front frame top, 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 similar slab structure part of cross sectional shape to the cavity of car front frame top corresponding site, is provided with a plurality of endoporus of circulation for liquid on the slab structure skeleton; The two sides of slab structure skeleton be connected with respectively a plurality of be used for vehicle body in the connecting element that is connected and fixed of corresponding component, described foaming body is inlaid in a side of slab structure skeleton.
Described slab structure skeleton is respectively equipped with step at the outer peripheral contour of an one side and each the endoporus periphery that inserts for each brace panel, and on step, being provided with a plurality of posts that are used for fixing foaming body, described foaming body is inlaid in respectively on each step and with each post and links to each other.
The described endoporus of circulation for liquid is four, and four endoporus are symmetricly set on the middle part of slab structure skeleton; Described connecting element is eight, four outer side edges that are separately positioned on four endoporus of a side of slab structure skeleton wherein, other four outer side edges that are separately positioned on four endoporus of another side of slab structure skeleton are respectively equipped with the endoporus that allows the interior corresponding link of vehicle body pass through on the slab structure skeleton on eight connecting element next doors.
The described connecting element that is separately positioned on two side outer side edges of the same endoporus of slab structure skeleton is crisscross arranged.
The described foaming body that is arranged on slab structure skeleton outer peripheral contour also is outward extended with and a plurality ofly can contacts the projection that links to each other with vehicle body.
" recessed " font foaming body that also is provided with a protrusion in the middle of the described slab structure skeleton links to each other with the foaming body that is arranged on four endoporus peripheries.
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 front frame 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, the car body panel on vibration isolating pad and front frame top and each brace panel 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 front frame 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.
