Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of background lights, in particular to a train carriage identification background light. Background Art
[0002] Train carriage signs vary widely, including train number signs, carriage serial number signs, seat signs, restroom signs, water room signs, fire extinguishing equipment signs, and emergency exit signs. These signs can be categorized by type as safety signs, warning signs, and reminder signs. Adding backlights to some signs can make them more eye-catching and visually appealing, and improve legibility in special circumstances, such as when visibility is reduced, to ensure passenger safety.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.
[0025] In the description of this utility model, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "provided with" and "provided with" that may appear should be understood in a broad sense. For example, the object "provided with" may be a part of the main body, or may be arranged separately from the main body and connected to the main body. The connection may be detachable or non-detachable. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0027] The present invention is further described in detail below with reference to the embodiments.
[0028] Specific embodiments of the train compartment identification background light provided by the utility model:
[0029] See also Figure 1-9 The train carriage identification background light includes a light box 1 and a box cover 2, which is hinged to the light box 1; the box cover 2 is a ring-shaped frame structure, and the light box 1 has a box opening on the front side. The outer corner of the box opening of the light box 1 is provided with a mounting hole 3 for connecting with the train carriage. The box cover 2 is located on the front side of the light box 1, and the light box 1 can be installed on the train carriage by passing a bolt through the mounting hole 3, and the body of the light box 1 is embedded in the wall of the carriage; the mounting hole 3 is a stepped hole, which can accommodate the head of the bolt without affecting the close fit of the box cover 2 to the light box 1.
[0030] The inner edge of the light box 1 is provided with an annular groove 4 for receiving an identification sheet 12. In this embodiment, the identification sheet 12 is a safety exit sign, and is provided with text and a pattern. The identification sheet 12 comprises a transparent plate painted black, with portions of the black paint hollowed out to form the text and pattern. This allows light from within the light box 1 to pass through the text and pattern, providing a safety reminder. The lid 2 positions the outer edge of the identification sheet 12; the annular groove 4 of the light box 1 positions the inner and outer edges of the identification sheet 12. The lid 2 presses against the outer edge of the identification sheet 12, ensuring proper positioning of the identification sheet 12 and facilitating the replacement of different identification sheets 12.
[0031] An L-shaped fastener 5 is provided on the lid 2, away from the hinged end. A buttonhole 6 with an L-shaped cross-section is provided on the light box 1, which mates with the fastener 5. Both ends of the buttonhole 6 extend to the surface of the light box 1. The L-shaped fastener 5 is made of elastic plastic or steel, and has an inclined surface on its outer end. When closing the lid 2, the fastener 5 elastically deforms through the inclined surface, allowing it to enter the buttonhole 6 from the front, securing the lid 2 in place. To open the lid 2, a tool is inserted from the bottom into the buttonhole 6, lifting the end of the fastener 5 to elastically deform it, and the lid 2 can be opened.
[0032] An LED light strip 7 is provided in the light box 1. A filter 8 is slidingly provided in the light box 1. The filter 8 is attached to the outside of the light strip 7. The sliding direction of the filter 8 is perpendicular to the extension direction of the light strip 7. The filter 8 is divided into different color areas along the sliding direction.
[0033] In this embodiment, the filter 8 comprises a transparent plastic plate, and the different color regions include, in sequence, a colorless region, a green region, a red region, a yellow region, and a blue region of equal width. The colorless region is formed by leaving the transparent plastic plate untreated. A green filter strip, a red filter strip, a yellow filter strip, and a blue filter strip are affixed to the outside of the transparent plastic plate, adjacent to the colorless region. Each region corresponds to the light strip 7 and fits in front of the light strip 7. To adjust, simply slide the filter 8 to move the desired color or colorless region in front of the light strip 7. Light from the light strip 7 then passes through the filter 8, emitting different colors that illuminate the identification plate 12, and then passes through the hollowed-out text and pattern on the identification plate 12, allowing it to be observed by the outside world.
[0034] Slide rails 9 are provided in the light boxes 1 at both ends of the light strip 7, and slide grooves 10 are provided on the side of the slide rails 9 facing the light strip 7 to support the sliding of the end of the filter 8; the filter 8 can slide along the slide groove 10 to change the position of the filter 8, thereby making the light strip 7 correspond to different color areas of the filter 8.
[0035] Because the train carriage is in an operating environment for a long time and has slight vibrations, in order to prevent the filter 8 from being misplaced along the slide groove 10 in a vibrating environment, in this embodiment, a rubber strip 11 is pasted on the inner side of one side wall of the slide groove 10, which contacts the end of the filter 8. The rubber strip 11 is tightly attached to the end of the filter 8. The rubber strip 11 is deformable, which will increase the sliding resistance of the filter 8. The filter 8 can still move under human drive. During the operation of the train, the rubber strip 11 can ensure that the filter 8 is not misplaced.
[0036] In order to ensure the uniformity of the light source in the light box 1, the light strip 7 is provided with several parallel strips, and the several light strips 7 are arranged at equal intervals; the filter 8 is divided into several sections corresponding to the light strip 7 one by one, and each section of the filter 8 is divided into different color areas along the sliding direction, and each section of the filter 8 is the same; in this way, when the filter 8 is moved, each light strip 7 can correspond to the same color at the same time; adding light sources in multiple positions ensures sufficient light sources and consistency of color adjustment without increasing the workload of color adjustment.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
