Technical Field
[0001] This utility model belongs to the technical field of lighting power supply boxes, and relates to a lighting power supply box for rail transit vehicles with an easy-to-maintain box door. Background Technology
[0002] The main drawbacks of existing lighting power supply boxes in rail transit vehicles in terms of their inability to be quickly inspected and repaired are low maintenance efficiency, long fault response time, and significant impact on operations. These shortcomings are usually related to the design of the lighting power supply box. Due to space constraints and considerations for the overall vehicle design, the lighting power supply box is often installed in hard-to-reach locations, or its maintenance interface design is not user-friendly, making it difficult for maintenance personnel to quickly diagnose and repair faults.
[0003] Conventional approaches include regular preventative maintenance to simplify the maintenance process. However, these methods also have drawbacks. While regular preventative maintenance can reduce unexpected failures, it increases operating costs and may lead to unnecessary inspections and replacements of equipment during non-failure periods, resulting in wasted resources. Therefore, there is an urgent need for a rail transit vehicle interior lighting power supply box with easily accessible access doors to address these issues. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lighting power supply box for rail transit vehicles with an easy-to-maintain box door, thereby solving the problems mentioned in the background technology.

The upper end of the front side of the front door is provided with a set of magnetic strips for magnetic attraction and adhesion with the front adsorption plate. The lower end of the magnetic strip inside the front door is provided with a set of handles to facilitate flipping the front door downwards. The front door and the rear door can be closed by using the magnetic strips and the adsorption strips.
[0010] In a preferred embodiment, the lower end of the handle is provided with a set of exhaust fans for guiding and discharging hot air from inside the power supply cavity, and the rear side of the side shell is provided with a set of rear doors for closing the rear side. The front door and the rear door are of the same specifications and are both movably connected to the side shell by hinges.
[0011] In a preferred embodiment, an insulating layer is provided on the inner side of both the front and rear doors, and a quick-inspection door is provided on the inner side of the left front end of the side shell to facilitate quick observation of the inside of the power supply cavity by the staff.
[0012] In a preferred embodiment, the upper end of the quick inspection door is provided with a set of hinges for movably connecting with the side shell, and the lower left end of the quick inspection door is provided with a set of pull heads. The quick inspection door rotates around the hinges as the axis, and the rear side of the quick inspection door is provided with a set of dust-blocking nets to prevent dust from entering. The quick inspection door allows staff to quickly inspect the equipment inside the power supply cavity.
[0013] In a preferred embodiment, the upper rear side of the quick-test gate is provided with two sets of power interfaces for outputting electrical energy from the power supply chamber, and the lower rear side of the quick-test gate is provided with a set of power plugs for introducing external power into the relevant equipment inside the power supply chamber.
