Background Art

[0002] During the operation of railway vehicles, battery boxes need to be ventilated to dissipate heat. Existing technologies mainly use three methods: open-hole ventilation hoods, filter-type ventilation hoods, and straight-through ventilation structures. Open-hole ventilation hoods are prone to the entry of fine debris such as dust and water vapor, causing battery short circuits or corrosion, and dust accumulation inside the box. Filter-type ventilation hoods require regular cleaning, have high maintenance costs, and have large airflow resistance. Straight-through ventilation structures cannot effectively block foreign matter such as insects and debris. Chinese patent CN 201720715596.2, "New ventilation device for battery boxes," uses an S-shaped maze structure. However, it has a complex structure, many components, and high installation and maintenance costs. Summary of the Invention

The combined installation of these two components results in a simple structure, low cost, and easy installation and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
