Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, specifically to a rail vehicle windshield. Background Technology

[0002] Windshields are typically installed on either side of the seats in rail vehicles to block the wind blowing in when the doors open and to isolate passengers. Some windshields also include handrails for passengers to hold onto. Existing windshield structures, such as the rail vehicle screen device disclosed in publication number CN204184363U, include a fiberglass base for blocking the wind, short curved handrails for gripping, and stainless steel handrails. This existing windshield structure is isolated from the seats and relies solely on bolts for fixation. This not only makes it difficult to fit tightly with the seats, easily creating gaps that could pinch passengers, but also requires strict manufacturing and installation precision to ensure that each component is installed correctly. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a windshield screen for rail vehicles, which reduces the gap between itself and the seat by connecting with the seat, and allows for flexible adjustment of the connection position during installation, thus facilitating installation.

[0004] The technical solution is as follows: a windshield screen for rail vehicles, comprising a windshield screen body and a handrail, one end of which is connected to the vehicle body and the other end is fixedly connected to the windshield screen body. The windshield screen body is fixedly connected to the bottom and side of the seat via connectors; the handrail is connected to the vehicle body via an adjustable connection structure, which includes a handrail connecting seat and a vehicle body connecting seat. The handrail connecting seat has an oblong hole extending along the axis of the corresponding position of the handrail. One end of the vehicle body connecting seat is fixedly connected to the vehicle body, and the other end can be fixedly connected to the oblong hole via bolts after the handrail and the windshield screen body are in place.

[0005] Furthermore, the handrail includes an upper handrail located at the top and a middle handrail located in the middle, and the upper handrail and the middle handrail are respectively connected to the vehicle body through the adjustable connection structure.

[0006] Furthermore, the waist-shaped hole is stepped, and when the handrail connecting seat and the vehicle body connecting seat are connected to each other by bolts, the head of the bolt can press against the bottom stepped surface of the waist-shaped hole, and the rod can pass through the waist-shaped hole and be threadedly connected to the vehicle body connecting seat.

[0007] Furthermore, the adjustable connection structure also includes a sleeve, which is slidably connected to the handrail. When the handrail connecting seat and the vehicle body connecting seat are connected to each other, the sleeve can be fitted onto the connection between the handrail connecting seat and the vehicle body connecting seat and fixed by a fastener.

[0008] Furthermore, the windshield screen body includes a windshield screen back panel and a windshield screen cover panel. The windshield screen cover panel is detachably connected to the windshield screen back panel. The bottom of the handrail is provided with a bottom connecting seat. The bottom connecting seat extends into the interior of the windshield screen body and is fixedly connected to the windshield screen body.

[0009] Furthermore, the windshield cover includes a spring sheet at one end and a connecting hole at the other end. After one end of the windshield cover is engaged with the flange of the windshield back panel by the spring sheet, the connecting hole at the other end is fixedly connected to the windshield back panel by screws.

[0010] Furthermore, the spring sheet is located at the upper end of the windshield cover, and the connecting hole is located at the lower end of the windshield cover.

[0011] Furthermore, the seat includes a seat body and a seat frame, the seat frame being located at the bottom and back of the seat body, the windshield body being connected to the seat frame, and the connection point of the windshield body being shielded by the seat body.

[0012] Beneficial effects: 1. By fixing the windshield body to the bottom and side of the seat respectively, the windshield body and the seat are connected as a whole, which can reduce the possibility of large gaps after assembly due to the two not being connected. On the other hand, it can make the stress on both better and reduce the possibility of damage.

[0013] 2. The handrail connector and the vehicle body connector are connected by a slotted hole, which makes the gap between the handrail and the vehicle body adjustable. This allows other positions to be installed first, and the handrail to the vehicle body connection to be installed last. Even if there is a deviation, as long as the deviation is not large, the handrail connector and the vehicle body connector can be reliably connected through the slotted hole, thereby reducing the installation and manufacturing precision requirements and facilitating installation.
