Description

Technical Field

[0001] This utility model relates to the field of rail transit lighting, and in particular to a ring light for rail transit vehicles and its installation structure. Background Technology

[0002] As the aesthetic requirements for vehicles increase, more and more urban rail vehicles are installing ring lights on the ceiling of their passenger compartments for decorative lighting. Currently, there are various installation methods for ring lights on the ceilings of rail transit passenger compartments. Some accessory structures are difficult to install on-site, and the installation methods are complex and time-consuming. If the main suspension points are mispositioned, correction is very troublesome and may require re-drilling. Uneven gaps and steps can affect the aesthetics and cannot be adjusted. Maintenance of ring lights requires quick-disassembly structures, such as screws directly fixing them to the passenger compartment or opening access doors, all of which affect the aesthetics to some extent. Furthermore, some installation structures make it difficult to maintain the ring lights, increasing the workload and cost of after-sales maintenance. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model proposes a ring light for rail transit vehicles that is easy to install and maintain.

The light source plate is installed on the light body, the lamp cover is connected to the light source plate, the lamp top plate is embedded in the lamp cover, and at least two first Z-shaped connectors are provided on the side of the light body.

[0005] In one embodiment, the lamp body is a regular polygon or a circular structure.

[0006] In one embodiment, the lamp body is provided with an anti-detachment structure for connecting the lamp body to the lamp top plate. When cleaning or performing maintenance on the ring light, the lamp top plate needs to be removed; the anti-detachment structure allows the lamp top plate to be suspended from the lamp body for easy maintenance.

[0007] In one embodiment, the anti-detachment structure includes a first fixed end, a second fixed end, and a rope hook. The first fixed end is fixed to the lamp body, the second fixed end is fixed to the lamp top plate, one end of the rope hook is connected to the first fixed end, and the other end of the rope hook is detachably connected to the second fixed end.

[0008] In one embodiment, a first handrail hole is provided at the center of the lamp body, and a second handrail hole is provided at the center of the lamp top plate. If a handrail is required at the installation location of the ring light, the fixed end of the handrail can pass through the handrail hole provided in the ring light and connect to the vehicle interior ceiling, which neither affects the appearance of the ring light nor the installation of the handrail.

[0009] In one embodiment, the axis of the first armrest hole is collinear with the axis of the second armrest hole.

[0010] Based on an inventive concept, this utility model also proposes an installation structure that enables pre-installation of ring lights on rail transit vehicles, facilitating maintenance and control of the gaps between the ring lights and the periphery of the interior roof panel.

[0011] The technical solution of this utility model is as follows: A ring light mounting structure for rail transit vehicles includes a bracket and an inner top plate.

The bracket has a ring light mounting hole in the middle position. The ring light is connected to the bracket through the ring light mounting hole. The bracket has second Z-shaped connectors at both ends. The inner top plate has a circular through hole in the middle position.

[0012] This utility model features a Z-shaped connector on the side of the lamp body. One side of the Z-shaped connector is locked onto the lamp body, while the other side is fixed to the mounting structure. This design provides a large contact area, even force distribution, and a stable connection that is not easily loosened or rotated. The ring lamp can be quickly detached from the mounting structure, facilitating subsequent maintenance.

[0013] The ring light and the interior roof panel are pre-assembled under the vehicle to facilitate control of the gaps around the ring light and the interior roof panel. The pre-assembled ring light, bracket and interior roof panel are then installed together onto the interior longitudinal beam of the railcar to complete the entire installation process.
