The invention discloses a pump body assembly, an electric compressor, an air conditioning system and a vehicle, the pump body assembly comprises at least one cylinder assembly, the cylinder assembly comprises a cylinder, a piston, a slip sheet, a spring and a mounting seat, the piston rolls in the cylinder in a matched mode, the slip sheet slides in the cylinder in a matched mode, the inner end of the slip sheet abuts against the piston, and the spring is supported at the outer end of the slip sheet. The mounting seat is mounted on the cylinder and supports the outer end of the spring; wherein an installation hole is formed in the air cylinder, the installation hole penetrates through the air cylinder in the direction from the outer end of the sliding piece to the peripheral face of the air cylinder, the installation base is installed in the installation hole, and a step face used for stopping the installation base is formed in the installation hole so as to prevent the installation base from moving towards the interior of the air cylinder assembly. The step surface is arranged in the mounting hole, so that the mounting depth of the mounting seat is limited through the step surface, the proper compression degree of the spring is ensured, the compression is not too loose or too tight, the sound of the sliding vane is reduced, and the reliability of the pump body assembly is improved.
本发明公开了一种泵体组件、电动压缩机、空调系统和车辆,泵体组件包括至少一个气缸组件,气缸组件包括气缸、活塞、滑片、弹簧和安装座,活塞配合在气缸内滚动,滑片配合在气缸内滑动,滑片的内端止抵于活塞,弹簧支撑在滑片的外端,安装座安装于气缸且支撑弹簧的外端;其中,气缸上形成有安装孔,安装孔沿着从滑片的外端向气缸的外周面的方向贯穿气缸,安装座安装于安装孔,安装孔内形成有用于止挡安装座的台阶面,以阻止安装座朝向气缸组件内运动。本发明通过在安装孔内设置台阶面,使安装座通过台阶面进行安装深度限制,保证弹簧的压缩程度合适,不至于压缩的过松或过紧,降低了滑片音,提高了泵体组件的可靠性。
