The invention discloses a compression component, an electric compressor, an air conditioning system and a vehicle. The bearing assembly is arranged on the crankshaft in a sleeving manner; the crankshaft is sleeved with the air cylinder, the air cylinder and the bearing assembly are distributed in the axial direction of the crankshaft, and a compression cavity is defined by the air cylinder, the bearing assembly and the crankshaft; the heat insulation structure is arranged on the inner wall of the compression cavity, and the heat conductivity coefficient of the heat insulation structure is smaller than that of the inner wall of the compression cavity. According to the compression component, the heat insulation structure is arranged on the inner wall of the compression cavity, the inner space of the compression cavity can be separated from the air cylinder and the bearing assembly, heat outside the compression cavity is prevented from being conducted into the compression cavity, it is guaranteed that the amount of low-pressure refrigerant enters the compression cavity, and the energy efficiency of the compression component is improved.
本发明公开了一种压缩部件、电动压缩机、空调系统和车辆,所述压缩部件包括:曲轴;轴承组件,所述轴承组件套设于所述曲轴;气缸,所述气缸套设于所述曲轴,所述气缸与所述轴承组件沿所述曲轴的轴向分布且与所述曲轴限定出压缩腔;隔热结构,所述隔热结构设于所述压缩腔的内壁,所述隔热结构的导热系数小于所述压缩腔的内壁的导热系数。本发明的压缩部件,通过在压缩腔的内壁设置隔热结构,可将压缩腔的内部空间与气缸、轴承组件间隔开,防止压缩腔外的热量传导至压缩腔内,保证压缩腔内进入到低压冷媒量,提高压缩部件的能效。
