Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-3, a give sound insulation and fill up for automotive interior, including giving sound insulation and fill up main part 100, give sound insulation and fill up main part 100 and comprise fibre spunbonded fabric 1, intermediate layer 2 and waterproof covering 3, fibre spunbonded fabric 1, intermediate layer 2 and waterproof covering 3 from the bottom up are laminated connection in proper order, give sound insulation and fill up the middle part of main part 100 and be provided with dodge hole 4, dodge hole 4 and run through waterproof covering 3, intermediate layer 2 reach fibre spunbonded fabric 1, intermediate layer 2 is in dodge the limit portion in hole 4 and be provided with a plurality of cards 21, still be provided with a plurality of through-holes 22 on the intermediate layer 2, the intussuseption of through-hole 22 is filled with the amortization cotton. Specifically, in this embodiment, during the use, the staff dismantles the loudspeaker cover (not shown in the figure) on the car qianmen earlier, then, glues sound insulating pad main part 100 on the qianmen, and it can be understood that, after fibre spunbonded fabric 1 glues on the qianmen, dodge hole 4 and loudspeaker cover and be just in time aligned, avoid influencing loudspeaker cover broadcast. At this time, the worker installs the horn cover again, and the interlayer 2 is clamped by the clamping piece 21 at the edge of the avoiding hole 4 by means of the horn cover, thereby further improving the connection strength between the sound insulation pad body 100 and the front door. Further, be provided with a plurality of through-holes 22 on intermediate layer 2, utilize through-hole 22 installation amortization cotton, avoid the amortization cotton to shift everywhere between intermediate layer 2 and waterproof covering 3, lead to waterproof covering 3 surface unevenness. It will be appreciated that when sound penetrates the interlayer 2, the sound absorbing cotton absorbs the sound waves, greatly reducing the impact of road noise on the occupants of the vehicle. Have waterproof covering 3 at 2 surface coverings of intermediate layer, utilize waterproof covering 3 to protect intermediate layer 2 and install the amortization cotton on intermediate layer 2, prevent in overcast and rainy weather, when the car qianmen was opened, rainwater etc. got into and give sound insulation and fill up inside, lead to the amortization cotton to wet, make its sound absorption effect reduce.

As shown in fig. 1 to 3, an edge-covering structure 31 is arranged at an edge of the waterproof skin 3, and the edge-covering structure 31 wraps the edges of the interlayer 2 and the fiber spunbonded fabric 1. Specifically, set up the structure of borduring at 3 limit portions of waterproof covering, avoid the user to drive when taking advantage of, shank and the limit portion friction of sound insulation pad lead to sound insulation pad limit portion turn-ups, spill the fibre spunbonded fabric 1 of bottom, lead to user's trousers and fibre spunbonded fabric 1 to glue, bordure structure 31 and play fine protection effect.

Specifically, in this embodiment, the waterproof skin 3 is made of a PU material, and the waterproof skin made of the PU material has good air permeability, is wear-resistant, and has good hand feeling when contacting with skin. The interlayer 2 is made of a foaming material infiltrated with damping rubber particles, and the damping rubber particles and the foaming material form the interlayer 2 with high elasticity, so that vibration of relevant frequencies can be well eliminated, and vibration and noise can be reduced.

Specifically, in this embodiment, the thickness of the interlayer 2 is 6-8 mm, and a modified resin adhesive is coated on the surface of the interlayer 2 adjacent to the waterproof skin 3.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
