Abstract
The utility model relates to a car body cavity vibration isolating pad arranged at the front part of a car top column, and comprises a heat resistant rigid framework and a foaming body which can foam and expand after being heated. The framework comprises an L-shaped panel and two legs connected on one side of the panel, the plane shape of the panel is similar to the sectional plane shape of the cavity of the corresponding part of the car top column front part, an inner hole for performing an elastic deflection is arranged on one side of the L-shaped panel, and the foaming body covers on the panel. After the car body cavity pre-arranged in the front part of the top column foams and expands, the utility model can be cohered closely with the car body plate and the reinforcing 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 car fore-set front portion.
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 fore-set front portion 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 fore-set front portion, be provided with brace panel in the bodywork cavity of described car fore-set front portion, 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 L shaped panel and is connected two legs of panel one side, the aspect of this panel is similar to the cross sectional shape of the cavity of the anterior corresponding site of car fore-set, be provided with the endoporus that is out of shape for elasticity on one side of L shaped panel, described foaming body covers on the panel.
Described panel is provided with a plurality of posts that are used for fixing foaming 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 of car fore-set front portion, 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 and the brace panel of vibration isolating pad and fore-set front portion closely are bonded to one, can intercept the cavity passage at this place effectively, reach totally-enclosed, thereby vibration source and noise that the anterior place of original fore-set 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.
Description of drawings
Fig. 1 is the perspective view that the utility model is arranged on the car body cavity vibration isolating pad of car fore-set front portion.
Fig. 2 is the structural representation of facing of the present utility model;
Fig. 3 is a side-looking structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, cooperate referring to Fig. 2, Fig. 3, the utility model is arranged on the car body cavity vibration isolating pad of car fore-set front portion, comprises skeleton 1 and foaming body 2, and skeleton 1 is made by heat-resisting high-intensity nylon 6-6, and foaming body 2 can foaming and intumescing after heating.Two legs, 12,13, two legs 12,13 that skeleton 1 in the utility model comprises a L shaped panel 11 and the is connected panel both sides elastically deformable column inside of can packing into behind the plastically deformable in welding process is fixed in the fore-set inner chamber firmly by elasticity.The aspect of this panel is similar to the cross sectional shape of the cavity of the anterior corresponding site of car fore-set, be provided with the endoporus 14 that is out of shape for elasticity on one side of L shaped panel, also be provided with a plurality of posts 15 that are used for fixing foaming body on the panel, foaming body 2 covers on the panel and is located and fixed by a plurality of post 15.
The car body cavity vibration isolating pad that the utility model is arranged on car fore-set front portion can be separately positioned on the corresponding site of left and right fore-set front portion.
