The invention discloses an electric compressor, an air conditioning system and a vehicle. The electric compressor comprises a shell assembly, the shell assembly comprises a first shell and a support, a first containing cavity is defined between the first shell and the support, and a liquid storage cavity is formed in the bottom of the first containing cavity; the compression mechanism is provided with a pump suction port; an air suction and liquid return structure is arranged on the support and comprises an air suction channel and an oil return hole, one end of the air suction channel is communicated with the first containing cavity and located above the liquid storage cavity, the other end of the air suction channel is communicated with the pump suction opening, the oil return inlet end of the oil return hole is communicated with the liquid storage cavity, and the oil return outlet end of the oil return hole is communicated with the air suction channel. According to the electric compressor, the liquid refrigerant can be prevented from directly entering the compression mechanism, the liquid impact generation probability is reduced, the operation load of the electric compressor is reduced, and internal abrasion generated by liquid impact is avoided. The oil return hole can guarantee smoothness of backflow lubricating oil, and accumulation of the lubricating oil is avoided.

    本发明公开了一种电动压缩机、空调系统及车辆。电动压缩机包括:壳体组件,壳体组件包括第一壳体和支架,第一壳体与支架之间限定出第一容纳腔,第一容纳腔的底部构成储液腔;压缩机构,压缩机构上设有泵吸口;支架上设有吸气回液结构,吸气回液结构包括吸气通道和回油孔,吸气通道的一端连通第一容纳腔且位于储液腔的上方,吸气通道的另一端连通泵吸口,回油孔的回油进端连通储液腔,且回油出端连通吸气通道。根据本发明的电动压缩机,可避免液态冷媒直接进入压缩机构内部,减少液击产生几率,降低电动压缩机的运行负载,避免液击产生的内部磨损。回油孔可保证回流润滑油的顺畅性,避免润滑油积聚。
