This utility model discloses a side window structure for a locomotive driver's cab, relating to the field of locomotive technology. It includes a fixed frame and a movable window slidably disposed within the fixed frame. A locking component is provided at the upper part of the fixed frame for locking or unlocking the movable window. A balancing and hovering component is provided at the lower part of the fixed frame for controlling the movable window to hover at any position. Window cleaning components are provided on both the inner and outer sides of the middle section of the fixed frame. This utility model combines three core functions: safety assurance, convenient operation, and intelligent maintenance, comprehensively improving the ergonomics, safety, and maintainability of the locomotive driver's cab side window, and is particularly suitable for the long-term, high-vibration, and dusty operating environment of locomotives.

The present application relates to the technical field of PVB film preparation, in particular to a high-barrier low-haze PVB interlayer and its preparation method and application. To solve the technical contradiction that the heat insulation performance, optical performance and mechanical performance of the PVB interlayer are difficult to be considered in the prior art, the present application adopts the following technical scheme: the PVB interlayer has a three-layer symmetrical structure, the skin layer is a high-molecular-weight PVB adhesive layer; the core core layer comprises a molecular weight gradient blending matrix formed by ultra-high molecular weight PVB and low molecular weight PVB. The matrix cooperatively disperses absorbing infrared barrier agent, reflective infrared barrier agent, core-shell structure ultraviolet stabilizer, toughening agent and flame retardant, and realizes high-efficiency interface bonding through silane coupling agent. Through the ingenious structure function partition and material composite design, the present application realizes high infrared barrier rate, maintains low haze, and has excellent mechanical performance and super-long weather resistance stability, and has excellent comprehensive performance.

A light mass transit vehicle sidewall assembly and associated long girders are provided that are lightweight, strong, safe, and easily adaptable to include panels in the assembly, and that are lighter than typical long girders while maintaining adequate stiffness and strength required to support the roof and associated components attached to the roof and securely connect to the light mass transit vehicle sidewall assembly.

A passenger rail vehicle includes an emergency exit, wherein the passenger space is divided into a plurality of compartments and the compartments are located on at least two levels, where two adjacent compartments have a common window having a pane, where the window forms the emergency exit, where a separating wall is provided between the adjacent compartments, where the separating wall is locked to the pane of the common window, and an interior trim part is fastened to the pane of the common window, and where an emergency exit aid that is stowed in its idle position is fastened both to the car body structure of the passenger rail vehicle and to the pane of the common window so that, when the pane is destroyed, the emergency exit aid is brought into its usage position by virtue of the pane falling into the open.

This application relates to the field of rail transit facility maintenance technology, and in particular to a roller shutter device. The roller shutter device provided in this application includes: a roller shaft, comprising a rotating shaft, a fixed shaft, and an elastic element, the fixed shaft being disposed inside the rotating shaft, and both ends of the elastic element being connected to the roller shaft and the fixed shaft respectively; a roller shutter, which is retractably wound around the rotating shaft; two supports, each disposed at one end of the roller shaft, the roller shaft being rotatable relative to the supports; and a winding assembly, including a ratchet and a pawl, the ratchet being connected to the rotating shaft for synchronous movement with the roller shaft, the fixed shaft being fixedly connected to the supports, the ratchet having multiple teeth distributed circumferentially on it, the pawl being pivotally connected to the supports, one end of the pawl engaging with the ratchet teeth, and the other end of the pawl having a rope component. The roller shutter device provided in this application helps to adjust the pre-stored potential energy of the elastic element, achieving convenient compensation of the roller shutter's rewind force, thereby simplifying the maintenance process and improving maintenance efficiency.

The application provides a kind of electric side window for rail vehicle and rail vehicle, including fixed frame, movable window assembly, drive mechanism and locking mechanism, movable window assembly includes movable window body and locking pin, movable window body is slidably arranged on fixed frame, locking pin is arranged on movable window body, the end of locking pin away from movable window body is provided with baffle edge;The output end of drive mechanism is connected with movable window body;Locking mechanism includes drive assembly and sliding lock stop, drive assembly is arranged on fixed frame, sliding lock stop is slidably arranged on fixed frame, drive assembly drives sliding lock stop to move between unlocking position and locking position to unlock or lock movable window assembly.In the application, drive mechanism drives movable window assembly to open or close, thereby reducing the work intensity when operating movable window assembly manually by driver, and locking mechanism can effectively ensure the locking effect of movable window assembly, simple and convenient to operate, which is conducive to improving the stability of electric side window for rail vehicle.

To provide a rail vehicle that improves strength against vertical loads while avoiding deterioration of manufacturability and increase in mass. [Solution] The rail vehicle consists of a roof structure that forms the top surface, a side structure that forms the sides, an end structure that forms the longitudinal end face of the side structure, a frame that forms the bottom surface, and a bogie that supports the frame. The side structure has a plurality of window openings arranged in the longitudinal direction of the rail vehicle and a winding section between the window openings. The diameter of the arc provided at the corner of the window opening located above the bogie is larger than the diameter of the arc provided at the corner of the window opening near the longitudinal center of the rail vehicle.
