The invention discloses a multiple-piece type tail wing portion structure. The multiple-piece type tail wing portion structure comprises two tail wing portion structure bodies, an airflow channel and a hydraulic pipeline, wherein the tail wing portion structure bodies are located at the tail end of the airflow channel, and each tail wing portion structure body comprises a main wing, an assistant wing and a driving mechanism, wherein the main wing is located below the assistant wing, the front end of the assistant wing is close to the tail end of the main wing, a locating plate fixed relative to the main wing is arranged on the middle of the upper plate surface of the main wing, the upper end of the locating plate is rotationally connected with the assistant wing, the driving mechanism comprises main wing cylinders, assistant wing cylinders, rotating assistant cylinders and a base, the cylinder body of each assistant wing cylinder is rotationally connected with the locating plate, and the hydraulic pipeline comprises a hydraulic pump, a main wing pipeline body used for connecting-breaking the two main wing cylinders simultaneously, an assistant wing pipeline body used for connecting-breaking the two assistant wing cylinders simultaneously and a rotating assistant pipeline body used for connecting-breaking each rotating assistant cylinder separately. The multiple-piece type tail wing portion structure has the advantages that the low pressure and the air resistance of the left side and the right side of an automobile tail can be adjusted, therefore, the adhesion performance of an automobile is improved, the load of tires is reduced, and the structure is used for adjusting the air resistance of the automobile tail.
