Abstract
The utility model relates to a vibration isolator of car body cavity in the front support of the car, comprising a heat-resistant plate-shaped frame and a foaming body in which can generate foam and expand after being heated up; wherein, a plurality of gaps and channels used for passing the liquid of pickling, neutralization, phosphatization and purification are arranged on the plate-shaped frame; a fixture is arranged at one side of the plate-shaped frame used for fixing the corresponding parts in the car body; the foaming body encloses the plate-shaped frame and is embedded at the inner sides of the channels by the gaps to enclose a plurality of inner holes; the foaming body enclosed the plate-shaped frame has a thickness which can fill in the clearance of the vibration isolator and the car body after foaming expansion, and the foaming bodies at the inner sides of the channels have a thickness which can fill in the holes after foaming expansion. The utility model has the advantages of enabling to bond with the car body plate after being preassembled in the car body cavity in the front support of the car, therefore separating the cavity channel and further improving the performances of car cockpits of vibration isolation, sound insulation, vibration damping and noise reduction.
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 front frame 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 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, described vibration isolating pad is plate shape on the whole, foaming body that can foaming and intumescing after comprising heat-resisting plate shape skeleton and being connected on the skeleton heating, whole have the aspect similar to the cross section of the bodywork cavity on car front frame top and leave gap for the foaming body foaming and intumescing with the peripheral car body panel of respective cross-section; On plate shape skeleton, be provided with a plurality of breach and for the passage of pickling, neutralization, phosphatization, purification of liquid circulation, a side of plate shape skeleton be provided with vehicle body in the connecting element that is connected and fixed of corresponding component; Described foaming body be enclosed in plate shape skeleton around and enclose a plurality of endoporus by the inboard that each breach is inlaid in each passage, be enclosed in plate shape skeleton foaming body on every side and have at the thickness that fills up the gap between vibration isolating pad and the car body panel behind the foaming and intumescing, the foaming body that is inlaid in each passage inboard has the thickness that fills up each endoporus behind foaming and intumescing.
Described connecting element is two buckle-type connecting elements.
Described plate shape skeleton is connected with a pair of fin perpendicular to plate shape skeleton panel respectively in the both sides of the side that closes on two connecting elements.
The periphery of described plate shape skeleton is provided with and a plurality ofly can contacts the post that links to each other with car body 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 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 closely is bonded to one, can intercept the cavity passage at this place effectively, reach totally-enclosed, thereby vibration source and noise that 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.
