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 in the right back longeron of car.
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, and can seal the car body cavity vibration isolating pad in the right back longeron of car of being arranged on that bodywork cavity can improve vibration in the 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 in the right back longeron of car, 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 vibration isolating pad have the aspect similar to the cross section of bodywork cavity in the right back longeron of car and leave gap for the foaming body foaming and intumescing with the peripheral car body panel of respective cross-section; A side of plate shape skeleton be provided be used for vehicle body in the connecting element that is connected and fixed of corresponding component, be outward extended with the column of a band cap head on the connecting element, be provided with outwardly open groove at the periphery of plate shape skeleton; Described foaming body is inlaid in the groove of plate shape skeleton periphery and has an autonomous block to link to each other with plate shape skeleton elasticity, and this autonomous block foaming body is provided with a through hole, and the column of described band cap head can pass this through hole the autonomous block foaming body is locked.
One side of described connecting element is provided with the socket that one group of corresponding component of buying car in installments in the body inserts, and opposite side is provided with one group of outstanding structure that links to each other with corresponding component in the vehicle body.
The described foaming body that is inlaid in the plate shape skeleton peripheral groove is outward extended with a projection on the next door of connecting element.
Through hole on the described autonomous block foaming body is a taper hole, is provided with the groove of a lateral direction penetrating at the osculum end of this taper hole, and after the column of described band cap head passed this through hole, its cap head was positioned at this groove.
A side of described autonomous block foaming body be provided be used for vehicle body in the jack that is connected and fixed of corresponding component.
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 in the right back longeron of car, 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, car body panel in vibration isolating pad and the right back longeron closely is bonded to one, can intercept the cavity passage at this place effectively, reach totally-enclosed, thereby the vibration source and the noise that import into through bodywork cavity in the original right back longeron are intercepted, 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.
