Description
Technical field
This utility model is with regard to a kind of automobile silencing apparatus, particularly a kind of new front wall sound-isolation pad device.
Background technology
Mute vehicle is automobile industry, particularly car etc., important performance indications.Wherein sound insulating pad is the heat for absorbing
And noise, while also playing a part of heat-insulated and vibration isolation, it is ensured that in-car relatively quiet comfortable environment, improve ride comfort
Property, sound insulating pad can obtain preferable defening effect using the double-wall construction of " hard formation material+soft formation material+panel beating ", sound insulation
Pad area coverage is bigger, and soundproof effect is better.
At present sound insulating pad is located at centre, and due to processing technology or its Surrounding Parts arrangement the problems such as cause sound insulating pad
Area coverage is less, and sound insulation value is poor.
And in prior art, front wall sound-isolation pad both sides without deadener, therefore front wall panel beating be greatly not covered with every
Sound pad, causes, impact driver's cabin NVH performance big through sound.
Utility model content
This utility model provides a kind of new front wall sound-isolation pad device, and which includes the middle sound insulation in the middle part of front wall panel beating
Pad, wherein also including between the side sound insulating pad positioned at the front wall panel beating both sides, and the side sound insulating pad and septum sound pad
It is fixedly connected, the side sound insulating pad is fixedly connected with the front wall panel beating.
This utility model increases the area coverage of sound insulating pad by side sound insulating pad, reduces front wall and passes through sound, improves NVH
Performance.Sound insulation pad body and capital need not change mould, reduces cost.
Description of the drawings
Fig. 1 is this utility model installation diagram；
Fig. 2 is this utility model schematic diagram；With
Fig. 3 is side sound insulating pad schematic diagram.
Reference：1 front wall panel beating, sound insulating pad in 2,3 side sound insulating pads, 4 location holes, 5 installing holes.
Specific embodiment
As shown in Figures 1 to 3, this utility model provides a kind of new front wall sound-isolation pad device, and which is included positioned at front wall panel beating 1
The middle sound insulating pad 2 at middle part, wherein also include the side sound insulating pad 3 positioned at 1 both sides of front wall panel beating, and the side sound insulating pad 3 with
It is fixedly connected between septum sound pad 2, the side sound insulating pad 3 is fixedly connected with the front wall panel beating 1.
This utility model increases the area coverage of sound insulating pad by side sound insulating pad, reduces front wall and passes through sound, improves NVH
Performance.Sound insulation pad body and capital need not change mould, reduces cost.
As further improvement, fixed by big staple between the side sound insulating pad 3 and septum sound pad 2 and connected
Connect, it is not necessary to change mould, simple structure.
Used as improved embodiment, as illustrated in fig. 1 and 2, the side sound insulating pad is longitudinally arranged along the front wall panel beating.Wherein
Fig. 2 is new front wall sound-isolation pad overall schematic, and Fig. 1 is and the hard-wired assembling schematic diagram of front wall panel beating.
As further improvement, as shown in figure 3, the side sound insulating pad 3 (including the side sound insulating pad of the left and right sides) has
The location hole 4 coordinated with the front wall panel beating 1.
As further improvement, as shown in figure 3, the side sound insulating pad 3 (including the side sound insulating pad of the left and right sides) has
The installing hole 5 being fixedly connected with the front wall panel beating 1.
Used as preferred embodiment, between the side sound insulating pad 3 and the front wall panel beating 1, buckle is fixedly connected.
As preferred embodiment, as shown in figure 3, the installing hole 5 has two.
Preferred embodiment of the present utility model, location hole 4 and installing hole 5 are respectively with the existing fabrication hole of panel beating and part phase
Coordinate, it is not necessary to change sheet metal mould.
Should be appreciated that this utility model scope of the claimed is not limited to non-limiting embodiments, it should be understood that non-limiting reality
Apply scheme to illustrate as just example.The protection domain of the application essence to be required more is embodied in independent claims
The scope of offer, and its dependent claims.
