Description

Technical Field

[0001] This utility model relates to the field of rail vehicles, specifically to a load-bearing frame. Background Technology

[0002] A hatch opening and closing mechanism is a device installed at the very front of a rail vehicle to open or close the hatch at the front of the vehicle. During normal operation, the hatch is closed to enclose components such as the coupler, forming a streamlined shape together with the vehicle's front cover, reducing wind resistance and enhancing the vehicle's aesthetics. When the rail vehicle is in multiple units or requires rescue, the hatch is open, exposing the internal cavity and providing the necessary space for coupler coupling.

[0003] The load-bearing frame connects the hatch opening and closing mechanism to the rail vehicle body. Locking mechanisms, electro-pneumatic control systems, and other components are housed on it to enable the hatch to open and close. It also withstands the aerodynamic loads generated by airflow acting on the hatch during high-speed rail vehicle operation, making it a crucial component of the hatch opening and closing mechanism. Existing metal-framed load-bearing hatch opening and closing mechanisms typically use welded steel components for their load-bearing frames, resulting in significant weight and low corrosion resistance.
