Abstract
The utility model discloses a cavity sound insulation block installed on the outer side of the upper portion of a column A of a sedan. The cavity sound insulation block comprises a high-temperature resistant support and a foaming body which is connected with the support and can foam and expand after being heated. The shape of the support is similar to that of the section of an upper side cavity of a sedan body of the column A of the sedan, and a gap is reserved between the support and peripheral sedan body plates with the corresponding section. One end of the support is provided with an elastic clamping buckle which is used for being connected with a cavity sound insulation block clamping sleeve arranged on the inner side of the upper portion of the column A. The cavity sound insulation block is prefabricated outside an upper side cavity of the sedan body of the column A of the sedan and can be bonded tightly with the sedan body plates in the position after being foamed and expanded so as to be integrated, a cavity channel in the position can be separated effectively, and therefore the purposes of vibration isolation, sound insulation, vibration attenuation and noise reduction outside a cabin of the sedan are further improved and enhanced.
Description
Technical field
The utility model relates to a kind of auto parts and components, relates in particular to a kind of cavity sound-insulation block that is arranged on the A pole of car upper outside.
Background technology
Along with the development of auto-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, and vibration and noise in the car passenger cabin are effectively improved.But the cavity passage in 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, first with sheet metal by the mould punching moulding after, formed by Automobile Plate metal seam such as inner panel, brace panel and outside plates.Therefore generally be bound to form necessary gap and space in the middle of inner panel and brace panel and outside plate, be included in the zones such as body platform beam, A, B, C, D column, rear wheel cover, ceiling, the front coaming plate of upper/lower terminal, ceiling, rear fender upper end 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 intensity and the rigidity of body structure effectively, so the cavity state in 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; Can form the sympathetic response sound to vehicle body because of extraneous blast, windage again in the high vehicle speeds motion; The pavement of road sandstone also can impact sound to vehicle body by on the go; The resonance frequency that produces in motion can form 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 vibration are delivered in the passenger cabin of car, affect driver and conductor's traveling comfort.
Summary of the invention
The purpose of this utility model, the problem that exists in order to solve above-mentioned prior art exactly, thus provide a kind of bodywork cavity that can seal can effectively improve car seat vibration out of my cabin and the cavity sound-insulation block that is arranged on the A pole of car upper outside of noise.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of cavity sound-insulation block that is arranged on the A pole of car upper outside, foaming body that can foaming and intumescing after comprising high temperature resistant support and being connected on support heating; Support have the shape similar to the cross section of A pole of car upper outside bodywork cavity and and the peripheral car body panel of respective cross-section between leave the gap, be provided with at an end of support the Elastic buckle that is connected for the cavity sound-insulation block cutting ferrule that is arranged on A post upper inner.
Described Elastic buckle is arranged on the inboard of support one end.
Rationally reach desirable task program in conjunction with the Automobile manufacturing technological process, bodywork cavity noise insulation block of the present utility model is arranged in the bodywork cavity of A pole of car upper outside, until body in white through pickling, neutralization, purifying, phosphatization, enters outside the stoving of the paint stove after first road paint again and toasts.In stove after 160～190 ℃ of high temperature and certain hour, foaming body is completed the foaming bonding, the car body panel of noise insulation block and A pole of car upper outside closely is bonded to one, can effectively intercept the cavity passage at this place, reach totally-enclosed, thereby make by A post upper outside and produce vibration source and the noise obstruct of importing into through bodywork cavity, reach the purpose of further improving the interior vibration isolation of car passenger cabin, sound insulation, vibration damping, noise reduction.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 arranged on the cavity sound-insulation block of A pole of car upper outside;
Fig. 2 is the plan structure schematic diagram of noise insulation block shown in Figure 1;
Fig. 3 is mounted in the structural representation of the cavity sound-insulation block of A pole of car upper inner;
Fig. 4 is the cavity sound-insulation block and the assembly drawing that is arranged on the cavity sound-insulation block of A pole of car upper inner that the utility model is arranged on the A pole of car upper outside.
The specific embodiment
Referring to Fig. 1, coordinate referring to Fig. 2, the utility model is arranged on the cavity sound-insulation block of A pole of car upper outside, comprise high temperature resistant support 1 and be connected on support after heating can foaming and intumescing foaming body 2; Support 1 have the shape similar to the cross section of A pole of car upper inner bodywork cavity and and the peripheral car body panel of respective cross-section between leave the gap, an end at support 1 is provided with the Elastic buckle 3 that is connected for the cavity sound-insulation block cutting ferrule that is arranged on A post upper inner, and this Elastic buckle 3 is arranged on the inboard of support 1 one ends.
Cooperation is referring to Fig. 3, Fig. 4, the utility model when mounted, the noise insulation block part snaps in the corresponding buckle 41 of the cavity sound-insulation block 4 that is arranged on A post upper inner by Elastic buckle 3, in the situation that be arranged on A post upper inner cavity sound-insulation block corresponding buckle 41 oneself snap in stamping holes, can fix part.Elastic buckle 3 tightly snaps in buckle 41 simultaneously, thereby buckle 3 firmly is fixed on stamping holes, makes panel beating hole can realize the installation of two parts (being that the utility model is arranged on the cavity sound-insulation block of A pole of car upper outside and is arranged on the cavity sound-insulation block of A pole of car upper inner).
