Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior decoration, and specifically to an automobile interior decoration sound insulation cotton which is convenient to disassemble and assemble. Background Art

[0002] Car interior mainly refers to car products used for car interior modification, among which sound insulation cotton is one of the important car interior decorations. Car interior sound insulation cotton is a material designed for car noise, which is more effective in improving car noise. However, during the use of existing car interior sound insulation cotton, due to external factors such as sweat and dust, the bolts and other fixing structures used to fix the sound insulation cotton become rusty, resulting in the overall disassembly and replacement process being more cumbersome and inconvenient to actually disassemble and assemble. At the same time, the surrounding areas of the sound insulation cotton, i.e. the middle part, are prone to curling and bulging.

[0003] After searching, the Chinese patent announcement number is CN215513508U, which discloses a car interior sound insulation cotton that is convenient for actual disassembly and assembly. The patent points out that the movable block pushes the rubber pad to complete the rapid installation of the sound insulation cotton body. When disassembling, it only needs to pull the sound insulation cotton body hard. At the same time, the magnet sleeve and the viscose pad are used to effectively fix the sound insulation cotton body on the outside of the installation part and prevent the bottom side from warping.

[0004] However, in the above scheme, although the sound insulation cotton body can be quickly replaced and disassembled, this method reduces the fixing effect of the sound insulation cotton body after installation, making it easy to fall off due to large vibrations. At the same time, the magnet sleeve structure can only be used to prevent the bottom of the sound insulation cotton body from warping. Utility Model Content
