Technical Field

[0001] The utility model relates to the technical field of skirt plates, and more specifically to a laser welded skirt plate. Background Art

[0002] Welded skirt is an important part of railway vehicle underframe, mainly used to provide vehicle appearance, protection of undercarriage equipment and improve aerodynamic performance. The structure and material design of skirt are crucial to ensure the operation safety and efficiency of railway vehicles.

[0003] Patent document CN214215784U discloses a laser welded skirt panel, wherein the reinforcement mechanism comprises a first transverse reinforcement plate, a second transverse reinforcement plate, a third transverse reinforcement plate and a vertical reinforcement plate, wherein the first transverse reinforcement plate is clamped with the vertical reinforcement plate, and the second transverse reinforcement plate is clamped with the vertical reinforcement plate. The utility model relates to the technical field of skirt panels. The laser welded skirt plate, through the coordinated use of the first transverse reinforcement plate, the second transverse reinforcement plate, the third transverse reinforcement plate and the vertical reinforcement plate, the first transverse reinforcement plate, the second transverse reinforcement plate, the third transverse reinforcement plate and the vertical reinforcement plate are welded together with the skirt plate body, thereby improving the strength of the skirt plate body, greatly reducing the thickness of the raw materials of the skirt plate body, thereby reducing the weight of the overall product, improving the practicality and reliability of the skirt plate body, and solving the problem that the skirt plates used on existing railway locomotives and vehicles use a large amount of angle steel and are thick, resulting in a large weight of the skirt plates. With respect to the above-mentioned related technologies, the utility model inventor believes that the existing mechanism for installing and fixing the skirt plate adopts the coordinated use of fixing parts and hinges, and then uses bolts to fix the fixing parts and the mounting parts, thereby fixing the skirt plate body. At this time, multiple bolts are used to fix the fixing parts to the mounting parts. This operation is relatively cumbersome and reduces the installation efficiency of the skirt plate. For this reason, we provide a laser welded skirt plate to solve the above problems. Utility Model Content
