The invention discloses a vibration isolation protective sleeve for an automobile air conditioner pipeline support, and belongs to the technical field of vibration and noise reduction of automobile air conditioner pipelines, the vibration isolation protective sleeve comprises a hollow rubber sleeve, rubber protrusions are evenly distributed on the inner side of the sleeve, the hardness of the protrusions is different, long rubber strips are further arranged, special vibration reduction effects are provided for different directions, and it is found through analysis that the vibration isolation protective sleeve is influenced by a vibration source in an automobile. The vibration direction is strong in a certain direction, a non-centrosymmetric structure and soft and hard alternate rubber protruding structures are adopted, the vibration device comprises an annular rubber column, a plurality of protruding structures arranged in parallel are arranged on an inner ring, the protruding structures are fixed at intervals, the hardness of the protruding structures is different from that of the annular rubber column, and the annular rubber column is provided with an opening. The whole annular rubber column is in an asymmetric center pattern, and all the structures are integrally formed. The damping device focuses on damping in the specific direction, and large amplitude caused by the fact that the rubber supporting columns are too soft is avoided. And therefore, the NVH performance of the vehicle air conditioning system is improved.
本发明公开了一种汽车空调管路支架用隔振护套,属于汽车空调管路减振降噪技术领域,包括空心橡胶套筒,套筒内侧均布橡胶凸起,凸起硬度不同,还设有长橡胶条,针对不同方向给予特殊减振效果,分析发现受车内振源影响,振动方向沿某一方向较为强烈,本发明采用非中心对称结构及软硬交替的橡胶凸起结构,包括环形橡胶柱,内圈设有多个平行布置的凸起结构,每个凸起结构间隔固定,凸起结构硬度与环形橡胶柱硬度不同,环形橡胶柱有开口,整个环形橡胶柱为非对称中心图形,所有结构一体成型。侧重于特定方向减振,且避免橡胶支撑柱过软引起的较大振幅。从而使车辆空调系统的NVH性能得到提升。
