Abstract
The utility model relates to a car body cavity vibration isolating pad arranged in a car rear longitudinal beam, and comprises a heat resistant rigid plate-shape structure framework and a foaming body which can be foamed and expanded after being heated and is connected on the framework. A plurality of fixing parts for firm connecting with the corresponding parts in the car body are connected on one side surface of the plate-shaped structure framework, and a plurality of inner holes for acid cleaning, neutralizing, coslettizing and depurate liquid flowing are respectively arranged on the plate-shaped structure framework beside the fixing parts. The foaming body is embedded on one side surface of the plate-shaped structure framework. After the utility model pre-arranged in the car body cavity in the rear longitudinal beam foams and expands, the utility model can be cohered closely with the car body plate and all the reinforcing plates into a whole, and the cavity channel 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 in the car floor side member.
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 car floor side member 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 car floor side member, described vibration isolating pad is plate shape on the whole, foaming body that can foaming and intumescing after comprising heat-resisting slab structure 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 car floor side member and leave gap for the foaming body foaming and intumescing with the peripheral car body panel of respective cross-section; A side of slab structure skeleton be connected with a plurality of be used for vehicle body in the connecting element that is connected and fixed of corresponding component, the supporting respectively endoporus that is provided with for pickling, neutralization, phosphatization, purification of liquid circulation on the slab structure skeleton on connecting element next door; Described foaming body is inlaid in a side of slab structure skeleton.
Described slab structure skeleton is respectively equipped with step at outer peripheral contour and each endoporus periphery of an one side, and described foaming body is inlaid in respectively on each step.
Described foaming body and connecting element are arranged on the same side of slab structure skeleton.
The described foaming body that is arranged on slab structure skeleton outer peripheral contour also is outward extended with two can contact the outstanding structure that links to each other with vehicle body, and two outstanding structures are arranged on the same side of slab structure skeleton and are splayed stretches out.
Described being on two outstanding structure foaming bodies that splayed stretches out is respectively equipped with a groove, and the part beyond the groove can bend inwards.
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 car floor side member, 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 floor side member and each brace panel closely are bonded to one, can intercept the cavity passage at this place effectively, reach totally-enclosed, thereby vibration source and the noise locating in the original floor side member to import into through bodywork cavity 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.
