The invention relates to the technical field of overhead vehicle-mounted air conditioners, in particular to a vibration and noise reduction device, a compressor and a vehicle-mounted air conditioner.The vibration and noise reduction device comprises a sound insulation cover and a base which are detachably connected, wherein the sound insulation cover sequentially comprises a sheet metal part, a nylon sheet and sound absorption cotton from outside to inside, and single-layer double-damping structures for reducing vibration of the compressor are further arranged on the base. According to the vibration and noise reduction device, the design of single-layer double-damping structure is adopted, the two single-layer double-damping structures are installed at the bottom end of the compressor inuse, so that the low-frequency vibration of the compressor and the generated noise are effectively reduced, and meanwhile, the high-frequency noise can be effectively reduced by utilizing the sound insulation cover; and vibration noise in the full frequency band generated in the working process of the horizontal compressor is effectively reduced through the combination of vibration reduction and noise reduction, and finally noise pollution to the environment surrounding the compressor is effectively avoided.

    本发明涉及顶置式车载空调技术领域,具体涉及一种减振降噪装置、压缩机以及车载空调器。该减振降噪装置包括:可拆卸连接的隔音罩和底座,所述隔音罩由外至内依次包括:钣金件、尼龙片以及吸音棉,所述底座上还设有用于降低压缩机振动的单层双减振结构;本方案采用单层双减振结构的设计,使用时是将两个单层双减振结构安装于压缩机的底端,从而可以有效降低压缩机的低频振动以及所产生的噪声,同时利用隔音罩即可有效降低高频噪声,本方案通过减振和降噪相互结合,从而有效降低卧式压缩机在工作过程中产生的全频段内的振动噪声,最终有效避免对压缩机周边的环境造成噪音污染。
