Abstract
A car-body cavity vibration-isolating pad equipped on the upper-middle part of the A column of a saloon car comprises a thermostable setsquare-shaped skeleton and a foaming body connected with the skeleton and foaming to expand after being heated, a fixture for being connected and fixed with corresponding parts in the car body extends outwards on one angle of the setsquare-shaped skeleton, and the foaming body wraps the periphery of the setsquare-shaped skeleton and has the foaming-expanded thickness that can fulfill the gap between the vibration-isolating pad and the car-body board. The utility model is preset in the car-body cavity at the upper-middle part of the A column of the car, and after expanding by foaming, the utility model can be closely integrated by adhering with the car-body board there, effectively blocking the cavity channel there and achieving the goal of further improving and enhancing vibration insulation, voice insulation, vibration reduction and noise reduction in the car cabin.
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 and upper 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, 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 the A pole of car middle and upper part 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 the A pole of car middle and upper part, described vibration isolating pad is plate shape on the whole, it have the aspect similar to the cross section of the bodywork cavity of A pole of car middle and upper part and and the peripheral car body panel of respective cross-section between leave the gap, foaming body that can foaming and intumescing after vibration isolating pad comprises heat-resisting set square shape skeleton and is connected on the skeleton heating, a jiao of set square shape skeleton be outward extended with one be used for vehicle body in the connecting element that is connected and fixed of corresponding component, foaming body is enclosed in the periphery of set square shape skeleton and has at the thickness that fills up the gap between vibration isolating pad and the car body panel behind the foaming and intumescing.
Described connecting element is the buckle-type connecting element.
Also be provided with two legs that are used for being connected the location on the face of described set square shape skeleton with the corresponding component in the vehicle body.
The periphery of described set square shape skeleton is provided with step, and described foaming body embedding shape is on step.
Described foaming body is provided with projection in the junction of connecting element.
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 of A pole of car middle and upper 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 170～190 ℃ of high temperature and certain hour, foaming body is finished the foaming bonding, the car body panel of vibration isolating pad and A pole of car middle and upper part 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 floor side member 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.
