Description

Technical Field

[0001] The utility model relates to the technical field of high-speed train skirts, in particular to a high-speed train skirt with wind resistance and drag reduction functions. Background Art

[0002] As the name suggests, the high-speed train skirt is a plate-like structure covering the side of the train body from the bottom of the body to the bottom edge of the door. It wraps the train body like a skirt. The main functions of the train skirt are: aesthetics, windproof, dustproof, rainproof, safety protection, etc.

[0003] With the application of composite materials in train bodies, the train bodies are lightweight while their strength and rigidity are significantly better than the aluminum alloy materials used in traditional trains. The body structure is modularly designed and integrally formed with composite materials, which reduces the complexity of the structure. The modular body structure enhances its overall rigidity through integrally formed crossbeams and longitudinal beams. Considering the convenience of maintenance, some skirt panels are designed as movable panels, which reduces the rigidity of the overall structure of the skirt panels.

[0004] The existing patent (publication number: CN217347792U) discloses a train bottom cabin skirt panel hanger assembly, in which a window is opened on a part of the skirt panel assembly corresponding to the maintenance component, and a movable skirt panel is correspondingly arranged. When maintenance is carried out, the movable skirt panel is flipped from its bottom to the outside to the maximum height, so that the guide column connected to the support on the movable skirt panel slides along the guide groove to the locking assembly, and the guide column is locked by the locking assembly to keep the movable skirt panel in a propped-up state; after the maintenance is completed, the locking state of the guide column by the locking assembly is released, so that the movable skirt panel falls, and finally the movable skirt panel is fixedly connected to the fixed hanger and the bottom plate respectively, so that the movable skirt panel cooperates with the fixed skirt panel and the bottom plate to achieve enveloping the bottom cabin, which can prevent impurities such as sand and gravel brought up by the ground from entering the bottom cabin during high-speed travel of the train, and can also reduce wind resistance and reduce the resistance of the bottom cabin components to the airflow, thereby reducing noise.

[0005] In view of the above problems, the existing patents provide solutions. The existing high-rise train skirts with wind resistance and drag reduction functions are generally composed of the installation of skirt bodies and metal connectors. At present, the sound insulation effect of such skirts is poor. The noise generated by the train operation contains various frequencies, and it is difficult for a single material to effectively reduce the noise of most frequencies.

[0006] Therefore, a high-speed train skirt with wind resistance and drag reduction function is proposed. Utility Model Content
