Document Type and Number:
WIPO Patent Application WO/2023/077571
Kind Code:
A1
Abstract:
Disclosed in the present invention are a door stopper structure and a railway vehicle. The door stopper structure comprises a base for being installed on a floor, and a support for being installed on a door leaf, wherein an upper surface of the base is provided with an attraction area and a stop protrusion, the attraction area comprises a limiting pit, and the gradient of a transition slope surface between an upper edge of the stop protrusion and an upper edge of the base is less than or equal to 1 : 2; and the support comprises a support body, a limiting component and an elastic component, the limiting component is movably connected to the support body in a liftable manner by means of the elastic component and extends out of a lower end of the support body, the limiting component can be magnetically attracted to the limiting pit, and the elastic component is used for applying downward pressure to the limiting component. In the door stopper structure provided by the present invention, the position of the door leaf can be limited by using a reliable attraction effect of the base and the support, and due to the smoother overall appearance of the base, the passing capability is significantly improved, thereby meeting the requirement for barrier-free passing, and improving the arrangement flexibility of an interior door of a railway vehicle.
