Document Type and Number:
WIPO Patent Application WO/2023/046015
Kind Code:
A1
Abstract:
The present application provides a pantograph deflector structure, a vehicle roof structure, and a rail vehicle. The deflector structure comprises: a deflector cover, the deflector cover being provided on a vehicle roof corresponding to a pantograph and being used to guide an airflow that flows through the pantograph, wherein the pantograph comprises a rising state and a lowering state, and the deflector cover at least covers the pantograph in the lowering state. In the pantograph deflector structure, the vehicle roof structure and the rail vehicle provided in the present application, by providing the deflector cover that may cover the pantograph, the pantograph is closed in the lowering state, thereby isolating the pantograph from external airflow, and reducing the aerodynamic drag in the pantograph region. Meanwhile, after the pantograph is isolated from the external airflow, the aerodynamic noise generated by lowering the pantograph is eliminated, thereby reducing the noise generated during the operation of the rail vehicle.
