Description

Technical Field

[0001] This utility model relates to the field of rail transit vehicle technology, specifically to a light-up handrail for rail transit vehicles. Background Technology

[0002] Handrails in rail transit vehicles are typically installed at the entrance or in the aisles for passengers to hold onto. Currently, most rail vehicle handrails have a monotonous aesthetic and clash with the overall interior ambiance of modern intelligent high-speed trains. To enhance market diversity and innovation, the support structure needs to be redesigned to accommodate other functional requirements, thereby improving the overall interior aesthetics and passenger experience. To this end, some handrails now incorporate built-in light sources, such as the structure disclosed in patent CN212709405U. This handrail has a long, narrow groove inside for installing ambient lighting. The light emitted penetrates the lampshade on the handrail surface and enters the carriage. However, since the ambient light and lampshade are bonded together, these components are prone to detachment, affecting the lifespan of handrails subjected to prolonged gripping and rail vehicle vibrations. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a luminous handrail for rail transit vehicles, which emits light through a built-in light source and a lampshade on the surface of the handrail. Furthermore, all components are securely installed and have a long service life.

[0004] The technical solution is as follows: A luminous handrail for rail transit vehicles includes a handrail body, a light panel, and a lampshade. The handrail body has an internal mounting cavity for mounting the light panel. The surface of the handrail body has a mounting groove extending axially and penetrating into the mounting cavity for mounting the lampshade. The light emitted by the light panel can pass through the lampshade and enter the carriage. The lamp panel is fixed to the inner wall of the mounting cavity by fixing screws. The lampshade has an I-shaped cross-section and includes an outer limiting part, an inner limiting part, and a connecting part between them. The inner and outer limiting parts are located on the inner and outer sides of the handrail body, respectively, and are connected by the connecting part that passes through the mounting groove. The width of the outer limiting part and the inner limiting part is greater than the width of the mounting groove, thus confining the lampshade within the mounting groove.

[0005] Furthermore, the mounting groove includes an extension section near the outer surface of the handrail body and a through section near the inner surface of the handrail body. The width and thickness of the through section correspond to the width and thickness of the connecting portion, respectively, and the width and thickness of the extension section correspond to the width and thickness of the outer limiting portion, respectively.

[0006] Furthermore, one end of the mounting groove is connected to the insertion groove, and the other end is closed to support the end of the lampshade. An enlarged section is provided on the insertion groove, and the lampshade is inserted into the mounting groove through the enlarged section.

[0007] Furthermore, the handrail body has an end opening, and the light panel is inserted into the handrail body through the end opening.

[0008] Furthermore, a removable plug is installed at the end of the handrail body, which is used to seal the end opening of the handrail body.

[0009] Furthermore, the mounting cavity is provided with a limiting guide groove extending along the axial direction of the handrail body, and the light panel is limited and guided by the limiting guide groove.

[0010] Furthermore, the limiting guide groove is located on both sides of the lamp plate and has a C-shaped cross-section.

[0011] Furthermore, the mounting groove is directly opposite the position on the light panel for mounting the fixing screw, and the user can insert the fixing screw into the armrest body and fix it on the light panel through the mounting groove.

[0012] Furthermore, the luminous handrail also includes a handrail base, and both ends of the handrail body are fixedly connected to the vehicle body through the handrail base.

[0013] Furthermore, the luminous handrail also includes a reinforcing rod, which is used to fill the internal gap of the handrail body at the mounting location of the handrail seat. The handrail seat, the handrail body, and the reinforcing rod are fixedly connected by connecting bolts.

[0014] Beneficial effects: The light emitted by the light panel can pass through the lamp cover and shine into the carriage to illuminate the handrail, thereby improving its aesthetics. At the same time, the light panel is fixed inside the handrail body by fixing screws, and the lamp cover is also restricted in the mounting groove by the I-shaped structure, which effectively prevents the light panel and lamp cover from falling off the handrail and ensures its service life.

[0021] Figure 7 Diagram showing the installation location of the illuminated handrail. Detailed Implementation

[0022] like Figure 1 , Figure 2 The illustrated luminous handrail of a rail transit vehicle includes a handrail body 1, a light panel 2, and a light cover 3, combined with... Figure 3 , Figure 4 As shown, the handrail body 1 has an internal mounting cavity 1-1 for mounting the light panel 2. The surface of the handrail body 1 has a mounting groove 1-2 extending axially and penetrating into the mounting cavity 1-1 for mounting the lampshade 3. The lampshade 3 can be made of semi-transparent polycarbonate, allowing light emitted from the light panel 2 to pass through the lampshade 3 and enter the passenger compartment. Figure 2 As shown, the light panel 2 is fixed to the inner wall of the mounting cavity 1-1 by fixing screws 4. In order to facilitate the installation of the light panel 2, preferably, the mounting groove 1-2 is directly opposite the position of the light panel 2 for installing the fixing screws 4. Of course, the relative positions of the two can be slightly offset as long as the user can insert the fixing screws 4 into the handrail body 1 and fix it on the light panel 2 through the mounting groove 1-2.

[0023] The lampshade 3 has an I-shaped cross-section and includes an outer limiting part, an inner limiting part, and a connecting part between them. The inner and outer limiting parts are located on the inner and outer sides of the handrail body 1, respectively, and are connected by a connecting part that passes through the mounting groove 1-2. The width of the outer limiting part and the inner limiting part is greater than the width of the mounting groove, so that the outer limiting part cannot pass through the mounting groove 1-2 to enter the mounting cavity 1-1, and the inner limiting part cannot pass through the mounting groove 1-2 to leave the interior of the handrail body 1, thereby restricting the lampshade 3 within the mounting groove 1-2.

[0024] Based on the above, in order to ensure aesthetics and grip comfort, combined with Figure 4 The mounting groove 1-2 includes an extension section 1-21 near the outer surface of the handrail body 1 and a through section 1-22 near the inner surface of the handrail body 1. The width and thickness of the through section 1-22 correspond to the width and thickness of the connecting part, respectively. The width and thickness of the extension section 1-21 correspond to the width and thickness of the outer limiting part, respectively. This arrangement allows the outer limiting part of the lampshade to sink into the extension section 1-21, thereby preventing it from protruding from the surface of the handrail body 1.

[0025] Although one end of the mounting groove 1-2 could extend through to the end of the handrail body 1, allowing the lampshade 3 to be directly inserted into the mounting groove 1-2 from the end of the handrail body 1, this would severely affect the strength of the handrail body 1. Therefore, as a preferred option, a combination of... Figure 3 , Figure 5 One end of the mounting groove 1-2 is connected to the insertion groove 1-3, and the other end is closed to support the end of the lampshade 3. An enlarged section 1-31 is provided on the insertion groove 1-3. The lampshade 3 is inserted into the mounting groove 1-2 through the enlarged section 1-31. This allows the lampshade 3 to be inserted into the mounting groove 1-2 at an angle during installation. At the same time, the enlarged section 1-31 can also be used for the wires of the lamp board 2 to pass through.

[0026] Regarding the installation of light panel 2, combined with Figure 1 The handrail body 1 has an end opening, and the light panel 2 is inserted into the handrail body 1 through the end opening. A removable plug 5 (e.g., via a threaded connection to the end) is installed at the end of the handrail body 1. The plug 5 is used to seal the end opening of the handrail body 1. Simultaneously, to limit and guide the light panel 2, combined with... Figure 4 The mounting cavity 1-1 is provided with a limiting guide groove 1-11 extending along the axial direction of the handrail body 1, and the limiting guide groove 1-11 limits and guides the light panel 2. Preferably, the limiting guide groove 1-11 is located on both sides of the light panel 2 and has a C-shaped cross section.

[0027] In addition, such as Figure 1 As shown, the illuminated handrail also includes a handrail base 6, and both ends of the handrail body 1 are fixedly connected to the vehicle body via the handrail base 6. To ensure connection strength and prevent deformation of the handrail body 1 due to its hollow structure, the illuminated handrail may also include... Figure 6 The reinforcing rod 7 shown is used to fill the internal gap of the handrail body 1 at the installation location of the handrail seat 6. Its shape can correspond to or partially correspond to the shape of the gap. The handrail seat 6, the handrail body 1 and the reinforcing rod 7 are fixedly connected by connecting bolts.

[0028] During installation, the light panel 2 is inserted into the handrail body 1 through the end opening. The fixing screw 4 is inserted into the handrail body 1 through the mounting groove 1-2 and tightened to fix the light panel 2. Then, the lampshade 3 is inserted into the mounting groove 1-2 through the enlarged section 1-31. After that, the power cord of the light panel 2 is pulled out from the enlarged section 1-31 so that it can be connected to an external power source. After the light panel 2 and lampshade 3 are installed, the reinforcing rod 7 is inserted into the end of the handrail body 1. The handrail base 6 is connected to the handrail body 1 and the reinforcing rod 7 through the connecting bolts. The end of the handrail body 1 is then sealed with the plug 5, thus completing the assembly of the luminous handrail.

[0029] The installed illuminated handrails can be installed... Figure 7At point C, which is on both sides of the door, or other locations, the light panel 2 can be an ambient light. The light source is hidden by the light cover 3 installed on the back of the handrail. The ambient light is built into the handrail tube, so it does not affect the use of the handrail in appearance, while meeting the functional requirements. The ambient light has a light color changing function, which is synchronized with the ambient light inside the train, enhancing the aesthetics of the entire interior. During train operation, especially when the train changes tracks, the flashing of the built-in light in the handrail reminds passengers to pay attention to safety and hold the handrail tightly. It can also be used as part of the flashing indicator light during the opening and closing of the train's sliding doors.

[0030] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
