[0023] Embodiment

[0024] As Figure 1-2 shown, an external indicator light applicable to urban rail vehicles includes a lamp body 2 and a lamp cover 4. One end of the lamp body 2 is provided with a circular plate, and a plurality of through holes are opened on the circular plate. The lamp cover 4 is a cavity structure with openings at both ends. One end opening of the lamp cover 4 is provided with a circular mounting plate, and a plurality of through holes are opened on the mounting plate. The lamp body 2 and the lamp cover 4 are connected by a first fastener 3. The first fastener 3 passes through the through holes on the circular plate and the mounting plate to fix the lamp body 2 and the lamp cover 4 on the vehicle body. The lamp body 2 is obliquely provided with a refraction plate 9 around it. One end of the refraction plate 9 is fixedly connected to the lamp body 2, and the other end of the refraction plate 9 is fixedly connected to the mounting plate of the lamp cover 4. A back plate 8 is detachably provided at the other end opening of the lamp cover 4, and the back plate 8 is fixedly connected to the lamp body 2 by a second fastener 6.

[0025] It is worth noting that the state of the rail vehicle is displayed by the lamp body 2, and the lampshade 4 is provided to protect the lamp body 2 and the circuit. Specifically, the annular plate on the lamp body 2 and the mounting plate on the lampshade 4 are used to fix the two together, and the two can be fixed to the vehicle body by fasteners 3. The vehicle body is provided with a mounting groove, so that the lampshade 4 can be embedded and installed on the vehicle body, avoiding the impact of the protruding lamp body 2 on the vehicle limit, and better conforming to the industrial design of the vehicle itself; the back plate 8 closes the opening behind the lampshade 4, and protects and stores the lamp body 2 and the circuit installed in the lampshade 4.

[0026] In particular, the lamp body 2 is surrounded by refraction plates 9 with an arc-shaped structure, which can refract the light emitted by the lamp body 2, so that the light that could originally directly illuminate a certain range is dispersed to a wider angle, thereby refracting the light emitted by the lamp body 2 to the area that could not be directly illuminated, thereby increasing the visible range of the light, allowing staff to observe the operating conditions and driving modes of rail vehicles at a farther distance and a larger range, and when a situation occurs, they can have more time to deal with it to avoid accidents.

[0027] In some feasible embodiments, a decorative cover 1 is further included, and the decorative cover 1 matches the mounting plate on the lampshade 4, and the decorative cover 1 and the mounting plate are detachably connected. When the lamp body 2 and the lampshade 4 are fixed to the vehicle body using the fastener 3, the decorative cover 1 is installed on the mounting plate of the lampshade 4 to cover the fastener 3, thereby achieving an aesthetic effect.

[0028] In some feasible embodiments, a plurality of buckles 5 are provided at the opening of one end of the lampshade 4 away from the mounting plate, and the side of the buckle 5 close to the inner wall of the lampshade 4 exceeds the side wall of the lampshade 4 and contacts the back plate 8. The buckle 5 limits the back plate 8 to prevent the back plate 8 from separating from the lampshade 4.

[0029] In some feasible embodiments, a wire outlet hole 7 of the lamp body 2 is opened on the back panel 7, and the signal line of the lamp body 2 passes through the wire outlet hole 7 and is connected to the connector of the signal line of the rail vehicle. The driving status of the rail vehicle will be transmitted to the lamp body 2 through the connector, and then the lamp body 2 will display it after receiving the signal.

[0030] When the indicator light needs to be inspected and repaired, it is only necessary to remove the decorative cover 1 and then remove the fastener 3, and the entire indicator light can be removed from the vehicle body for relevant inspection and repair. After completion, the lamp body 2 and the lamp cover 4 can be installed in the installation groove of the vehicle body using the fastener 3.

[0031] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment only contains an independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art. So far, the embodiments of the present disclosure have been described in detail. To avoid obscuring the concept of the present disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description. The scope of the present disclosure is defined by the appended claims.
