Description
Technical field
The present invention relates to a kind of auto parts and components, relate in particular to a kind of rear wheel cover noise insulation block of car and application thereof.
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, 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 source of internal car noise comprises air-flow noise, motor noise, chassis noise, wheel cover noise and tail gas noise.In addition, 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
Purpose of the present invention 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 rear wheel cover noise insulation block of car and the application thereof of noise effectively.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of rear wheel cover noise insulation block of car, be rectangular 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 noise insulation block have the aspect similar to the cavity cross section in the car rear wheel cover and leave gap for the foaming body foaming and intumescing with the periphery of respective cross-section; Side at plate shape skeleton is provided with two openings, be provided with at the middle part of plate shape skeleton two ducts and respectively with above-mentioned two open communication, the connecting element that the corresponding component in the periphery of plate shape skeleton is provided with at least one and rear wheel cover is connected and fixed; Described foaming body be inlaid in plate shape skeleton around, the inboard filling up two openings and be inlaid in two ducts encloses two endoporus for pickling, neutralization, phosphatization, purification of liquid circulation, be inlaid in plate shape skeleton foaming body on every side and have at the thickness that fills up the gap between noise insulation block and the rear wheel cover behind the foaming and intumescing, the foaming body that is inlaid in inboard, two ducts has the thickness that fills up two endoporus behind foaming and intumescing.
Described connecting element is three, and it is connected to the dual-side of plate shape skeleton and an end limit and perpendicular to the same side of plate shape skeleton.
Described three connecting elements respectively comprise a pair of perpendicular to the supporting blade of plate shape skeleton panel and the adapter plate that is connected a pair of supporting blade outside, and adapter plate stretches out perpendicular to plate shape skeleton panel and to plate shape skeleton panel periphery.
The described plate shape skeleton foaming body on every side that is inlaid in extends outward a dihedral projection at an angle end of plate shape skeleton, the described connecting element that is connected plate shape skeleton one end limit is arranged on the plate shape skeleton that closes on the dihedral projection, side of adapter plate in this connecting element and dihedral projection forms a unified side, and adapter plate and being inlaid between the foaming body on the plate shape skeleton fuses by foaming body.
The periphery of described plate shape skeleton also is provided with at least one breach, and the foaming body that is inlaid on the breach also forms corresponding breach.
Described plate shape skeleton and the connecting element that connects thereon form for the raw material manufacturing with PA66.
Described rear wheel cover noise insulation block of car is applied in the prompt M2 vehicle of Chinese fine horse.
In in conjunction with the Automobile manufacturing technological process, rationally reach desirable task program, noise insulation block of the present invention is arranged in the car rear wheel cover, toast by the time body in white through pickling, neutralization, purifying, phosphatization, enters in the stoving of the paint stove behind first road paint again.In stove behind 160～190 ℃ of high temperature and certain hour, foaming body is finished the foaming bonding, noise insulation block and rear wheel cover car body panel closely are bonded to one, can intercept the cavity passage at this place effectively, reach totally-enclosed, thereby vibration source and noise that original rear wheel cover 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 noise insulation block foams and bonds, also further reinforced the intensity of rear wheel cover in rear wheel cover, rear wheel cover structure and crash-protective characteristics have all been played optimization function, made the traveling comfort of car and safety obtain important lifting.
