Abstract
Disclosed is a sound isolation block of a hollow cavity of a car body, which is arranged on the upper portion of C and D columns of a car. The utility model includes a thermotolerant slab-shaped framework and a foaming body which is connected to the framework and is capable of foaming and swelling after being heated. The slab-shaped framework is provided with a flat surface which is similar to the cross section of the hollow cavity of the car body placed on the upper portion of the C and D columns of the car, the flat surface keeps gap with a peripheral car body board of the corresponding cross section, the periphery of the slab-shaped framework is provided with a loop of grooves, the inner portion of one groove is provided with stationary parts used to locate and connect with corresponding parts placed inside the car body, and the foaming body is embedded in the grooves of the slab-shaped framework. The utility model is prearranged in the hollow cavity of the car body placed on the upper portion of the C and D columns of the car. After the utility model foams and swells, the utility model is closely bonded together, and a hollow cavity passage of the car body is effectively blocked, thereby achieving the purposes of further improving and increasing the vibration isolation, sound isolation, vibration damping and noise reduction of the inner portion of a cabinet of the car.
Description
Technical field
The utility model relates to a kind of auto parts and components, relates in particular to a kind of bodywork cavity noise insulation block that is installed in car C, D post top.
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 bodywork cavity noise insulation block that is installed in car C, D post top of noise effectively.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of bodywork cavity noise insulation block that is installed in car C, D post top, foaming body that can foaming and intumescing after comprising heat-resisting plate shape skeleton and being connected on the skeleton heating; Plate shape skeleton have the aspect similar to the cross section of the bodywork cavity on car C, D post top and and the peripheral car body panel of respective cross-section between leave the gap, around plate shape skeleton, being provided with a circle groove and in place's groove, being provided with one and be used for being connected the connecting element of locating with corresponding component in the vehicle body; Described foaming body is inlaid in the groove of plate shape skeleton.
Described connecting element comprises an elasticity fixture block that stretches out along the direction of extension of groove.
In in conjunction with the Automobile manufacturing technological process, rationally reach desirable task program, bodywork cavity noise insulation block of the present utility model is installed in the bodywork cavity on car C, D post top, 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 on noise insulation block and car C, D post top closely is bonded to one, can intercept the cavity passage at this place effectively, reach totally-enclosed, thereby make by C, D post top and produce the vibration source and the noise obstruct of importing into, reach the purpose of further improving the interior vibration isolation of car passenger cabin, sound insulation, vibration damping, noise reduction through bodywork cavity.Simultaneously, after the bodywork cavity noise insulation block 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 installed in the bodywork cavity noise insulation block on car C, D post top;
Fig. 2 is the structural representation of facing of noise insulation block shown in Figure 1;
Fig. 3 is the side-looking structural representation of noise insulation block shown in Figure 1.
The specific embodiment
Referring to Fig. 1, cooperation is referring to Fig. 2, Fig. 3, the utility model is installed in the bodywork cavity noise insulation block on car C, D post top, be used for being preset in the bodywork cavity on car C, D post top at the manufacturing process of vehicle body, be plate shape on the whole, comprise plate shape skeleton 1 and foaming body 2, integral body has the similar aspect in cross section to the bodywork cavity on car C, D post top, and leaves gap for the foaming body foaming and intumescing with the peripheral car body panel of respective cross-section.Plate shape skeleton 1 is made by heat-resisting high-intensity nylon 6.6, can foaming and intumescing after foaming body 2 heating fills up the gap between noise insulation block and the car body panel.
Be provided with a circle groove around the plate shape skeleton 1 in the utility model and be provided with a connecting element 3 that is used for being connected with the corresponding component in the vehicle body location in place's groove, this connecting element 3 comprises an elasticity fixture block 31 that stretches out along the direction of extension of groove.
Foaming body 2 in the utility model is inlaid in the groove of plate shape skeleton, and has at the thickness that fills up the gap between noise insulation block and the car body panel behind the foaming and intumescing.
