A step is arranged at the periphery of the basic framework, the foam object is embedded on the step and is enclosed at the periphery of the basic framework, the thickness of the foam object enclosing the basic framework is able to be filled the gap between the vibration insulation pad and the car body after foam inflation. The utility model is preliminarily arranged in the car body cavity that is inflated after foam, which is able to be tightly bonded to the inner and outer boards of the body as a whole and effectively blocks and seals the cavity passage in relevant positions of the car body so as to improve and enhance the performances of the cabin of the car such as vibration insulation, noise screening, shock absorption and noise decreasing as well as improve the strength of the car body.
Description
Technical field
The utility model relates to a kind of auto parts and components, relates in particular to a kind of uni-body cavity vibration-isolating cushion.
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 enclosure sound heat insulating mattress, car internal sound insulation, vibration isolation carpet, vehicle body sticking glass, car roof etc. before ride-control, the front and back 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 the column structure spare that necessary gap and space, particularly Reinforcement A, B, C, D post and two bottom sides longeron have all formed 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 uni-body cavity vibration-isolating cushion of noise effectively.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of uni-body cavity vibration-isolating cushion, be characterized in, described uni-body cavity vibration-isolating cushion is an integral slab shape framing member that is constituted by basic skeleton and foaming body, it has the similar aspect in cross section of the cavity of relevant position with vehicle body, and leave for the gap of foaming body foaming and intumescing and the required fluid passage gap of technology in early stage, several roads that before stoving of the paint technology, must carry out for body in white with respect to the periphery of respective cross-section, the periphery of described basic skeleton is provided with step, described foaming body be inlaid on this step and be enclosed in basic skeleton around, the foaming body that is enclosed in around the basic skeleton has at the thickness that can fill up the gap between vibration isolating pad and the vehicle body behind the foaming and intumescing.
One end of described basic skeleton is provided with and is used for and connecting element that body contact is fixing, and is provided with at least one in other place of periphery and is used for contact with vehicle body the projective structure that links to each other and make it can be better keep good supporting and fix with bodywork cavity.
Also be provided with a fixture block that can link to each other with the corresponding component cutting ferrule in the vehicle body on the described basic skeleton, this fixture block is arranged on and the relative end of connecting element on the basic skeleton, and has and can contact the plane that links to each other with pairing vehicle body.
The described connecting element that is arranged on basic skeleton one end is the buckle-type connecting element.
The thickness of the centre portion of described basic skeleton is less than the thickness of peripheral steps part, and at pit of side formation of basic skeleton, described step is arranged on a side opposite with this pit.
The described foaming body that is enclosed in around the basic skeleton can also be provided with at least one can contact continuous projection with pairing vehicle body.
In in conjunction with the Automobile manufacturing technological process, rationally reach desirable task program, a plurality of the utility model uni-body cavity vibration-isolating cushions are arranged among the appropriate location that must intercept in the bodywork cavity, 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 in the uni-body cavity vibration-isolating cushion is finished the foaming bonding, vibration isolating pad and the inside and outside plate of body in white closely are bonded to one, can intercept the cavity passage in the relevant position in the former vehicle body effectively, reach totally-enclosed, thereby vibration source and the noise locating to import into through bodywork cavity through floor bearer, rear wheel cover, ceiling, dash shield, door-plate etc. are originally intercepted, reach the purpose of further improving the interior vibration isolation of car passenger cabin, sound insulation, vibration damping, noise reduction.Simultaneously, after the uni-body cavity vibration-isolating cushion 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.
