本発明は車両用サンドイツチ型防音、防振構造
体及びその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a sandwich type soundproofing and vibrationproofing structure for a vehicle and a method for manufacturing the same.
(従来技術)
車両の床部分にはエンジンの振動や排気系の騒
音等が主として下方から作用し、車室内に該振動
が伝わつたり、あるいは低周波数の騒音が、いわ
ゆるこもり音として車室内に入り、運転者や同乗
者に不快感を与えがちである。(Prior art) Engine vibrations, exhaust system noise, etc. mainly act on the floor of a vehicle from below, and these vibrations are transmitted into the passenger compartment, or low-frequency noise enters the passenger compartment as so-called muffled noise. This tends to cause discomfort to the driver and passengers.
そこで、車体床の制振性能、遮音性能が要求さ
れることとなり、近年は特にかかる要望が大とな
つている。 Therefore, vibration damping performance and sound insulation performance of the vehicle body floor are required, and such demands have become particularly important in recent years.
しかして、上記要求を達成するため上記車体床
をいわゆるサンドイツチパネル形式にする手段が
最近採用され始めている。 In order to meet the above requirements, methods have recently begun to be adopted in which the vehicle body floor is constructed in the form of a so-called sandwich panel.

ート2をフロアパネル3と一体化させんとしたも
のである。 As shown in FIGS. 1 and 2, the conventional sanderch panel has a structure in which a vehicle side panel, for example, a floor panel 1, is made of a polymeric viscoelastic material with a high specific gravity and a bituminous damping material ( A so-called Melsheet 2 as a soundproofing and vibration-proofing material mainly made of (for example, thermoplastic rubber, etc.) is arranged, and a floor upper panel 3, for example, as a holding panel for the Melsheet 2 is placed on top of it. The Melsheet 2 is integrated with the floor panel 3 by heating and fusing the Melsheet 2 by passing it through a heating booth in an intermediate painting process.
該サンドイツチパネルSはその上に配設される

働して、制振性能と防音性能を飛躍的に向上させ
ることが可能である。 The sandwich panel S cooperates with the felt 4 and the carpet 5, which have high sound-absorbing performance and are disposed thereon, to dramatically improve the vibration-damping performance and the sound-insulating performance.

生じ、上記したサンドイツチパネルSとしての所
期の性能を発揮することができない状態になる場
合があつた。 However, during heat curing work, the Melsheet 2 first expands by a predetermined amount by heating, and then shrinks due to fusion, so that after shrinking, there is a gap between the floor panel 1 and Melsheet 2 or the Melsheet 2 and the floor upper panel 3. In some cases, voids were formed, making it impossible for the above-mentioned sandwich panel S to exhibit its intended performance.

ボス等の凹凸の多い部位では、上記メルシート2
のみでは所期の溶着率の確保が困難となる問題を
有していた。 That is, in the conventional sand bench panel S, it is relatively easy to ensure a good welding rate in areas where the surface changes are small, such as the needle lower panel, but it is relatively easy to ensure a good welding rate in areas where the surface changes little, such as the needle lower panel. For areas with many unevenness, use Melsheet 2 above.
There was a problem in that it was difficult to secure the desired welding rate if only the welding method was used alone.
サンドイツチパネル構造体では、車両側パネル
と押えパネル間に空隙部(空気層)が存在した場
合、特に防振性能の立場からすると該空隙部の存
在により性能が低下するため、品質面からも融着
率の向上が解決すべき課題として残されていた。 In the sandwich panel structure, if there is a gap (air layer) between the vehicle side panel and the holding panel, the presence of the gap will reduce the performance, especially from the standpoint of vibration damping performance, so it is also important from the quality point of view. Improving the fusion rate remained an issue to be solved.

なる。(Effects of the Invention) In the present invention having the above configuration, in addition to the heat-welding type sheet that has been commonly used as a soundproofing and vibration-proofing material for sanderch panels,
By combining heat foam type sheets,
The heat foaming type sheet foams when heated, and the foaming pressure of the heat welding type sheet and the heat foaming type sheet creates gaps between the vehicle side panel and the holding panel at irregularities such as beads and embossments where gaps are likely to occur. In addition, due to the foaming pressure during foaming and the reaction force from the heat-welding type sheet, the adhesion to the vehicle side panel and the presser panel is further increased, and the restraining force between the vehicle side panel and the presser panel is increased. As a result, the adhesion and degree of welding as a sanderch type structure are significantly improved compared to conventional examples, making it possible to dramatically improve soundproofing and vibrationproofing performance.

Only the heat-welding type sheet 2 is placed on top and heated to a predetermined temperature or higher using a heating device or a painting oven to weld it to the floor panel 1 in advance, and then the heat-foaming type sheet 2 is placed on the floor panel 1 as shown in Figure 9. The sheet 6 is placed on the heat-welding type sheet 2, and then the floor upper panel 3 as a holding panel is placed as shown in FIG. As in Example 1, the heat-foamable sheet 6 is heated in a coating oven at 110°C or higher for about 20 to 30 minutes to foam the air gap between the floor upper panel 3 and the heat-welded sheet 2. The sandwich panel S is formed by densely filling the parts.

等の特有の効果を奏しうる。 In this embodiment, since the heat-welding type sheet 2 is tightly welded to the floor panel 1 as the vehicle side panel in advance, the heat-welding type sheet 2 is heated to a temperature higher than enough to foam the heat-foaming type sheet 6 during the second heating. Only heating is required, and in the second heating, it is only necessary to foam the heat-foamable sheet 6 to fill the voids, so the foaming pressure etc. can be set lower than in the first embodiment. It can produce unique effects such as:

しうるものである。 In this embodiment, the upper and lower heat-welding type sheets 2 can be tightly welded to the floor panel 1 and the floor upper panel 3 due to the foaming pressure of the heat-foaming type sheet 6, so that the floor upper panel 3 as a presser panel is particularly advantageous. The adhesion between the sheet layer and the sheet layer can be further improved.
