Description

Technical Field

[0001] This utility model relates to the field of lighting technology for rail vehicles, and in particular to a long strip-shaped signal indicator with a multi-curved appearance. Background Technology

[0002] Signal indicator lights on rail vehicles are key components installed at the front of the train, used to provide operational status indications (such as forward, braking, and reversing), location markers, and safety warnings. They must have high visibility, weather resistance, and compatibility with the streamlined design of the train body to ensure both driving safety and aesthetics.

[0003] However, existing signal indicator lights for rail vehicles mostly adopt a flat or simple arc design, which is difficult to fit the complex curved contour of the front of the vehicle. Additional processing of fitting brackets or filling pads is required, which increases the assembly complexity and cost. Utility Model Content

[0004] The purpose of this utility model is to provide a long strip-shaped signal indicator with a multi-curved appearance, which solves the problem that existing signal indicator lights for rail vehicles mostly adopt a flat or simple arc design, which is difficult to fit the complex curved contour of the front of the vehicle, and requires additional processing of fitting brackets or filling pads, increasing assembly complexity and cost.

[0005] To achieve the above objectives, this utility model provides a long strip signal indicator with a multi-curved appearance. The long strip signal indicator includes a lamp body, a lamp cover, and a light source module. The back of the lamp body is fixed to the indicator mounting location on the front of the rail vehicle by multiple M5 hex bolts. The lamp cover is provided on the front of the lamp body, and the light source module is provided inside the lamp body. The illumination end of the light source module corresponds to the lamp cover. The lamp body has continuous gradient curved surfaces in the X-axis, Y-axis and Z-axis directions. The X-axis is the length direction, the Y-axis is the width direction and the Z-axis is the height direction. The gradient curved surface of the X-axis is a wavy arc along the length direction of the lamp. The gradient curved surface of the Y-axis is convex along the width direction of the lamp and matches the front profile of the rail vehicle. The gradient curved surface of the Z-axis is a spiral twist structure of the lamp body in the vertical direction.

[0006] The back of the lamp body is also provided with a wiring terminal, one end of which is connected to the light source module, and the other end of which is connected to an external cable.

[0007] The light source module includes a flexible circuit board and a surface-mount LED strip. The flexible circuit board is installed inside the lamp body and is located on the side of the lamp body away from the lamp cover. The side of the flexible circuit board away from the lamp cover is connected to the wiring terminal. The surface-mount LED strip is provided on the side of the flexible circuit board close to the lamp cover.

[0008] The patch LED light strip has multiple LED light bead units evenly arranged on it. Each LED light bead unit consists of a first light bead and a second light bead arranged side by side.

[0009] The lamp body has a mesh-type heat dissipation structure on the side away from the lamp cover, and the flexible circuit board is installed on the mesh-type heat dissipation structure.

[0010] This utility model discloses a long strip-shaped signal indicator with a multi-curved appearance, comprising a lamp body, a lamp cover, and a light source module. The back of the lamp body is fixed to the indicator mounting location on the front of a rail vehicle using multiple M5 hexagonal bolts. The lamp cover is located on the front of the lamp body, and the light source module is located inside the lamp body. The illumination end of the light source module corresponds to the lamp cover. The lamp body has continuous gradient curved surfaces in the X-axis, Y-axis, and Z-axis directions: the wavy arc of the X-axis enhances the fit with the front of the rail vehicle; the convex curved surface of the Y-axis directly matches the external contour of the front of the rail vehicle; and the spiral torsion structure of the Z-axis compensates for differences in the vertical mounting surface. The lamp body, with the above-mentioned three-dimensional curved surfaces, can fit tightly with the complex streamlined shape of the front of the rail vehicle without the need for additional brackets or shims. During installation, it only needs to be fixed with the M5 hexagonal bolts, making the assembly process convenient. Furthermore, since no additional brackets or shims are required during installation, the overall installation cost of the indicator is reduced. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 4 This utility model provides a long strip signal indicator with a multi-curved appearance. The long strip signal indicator includes a lamp body 101, a lamp cover 102, and a light source module. The back of the lamp body 101 is fixed to the indicator mounting position at the front of the rail vehicle by multiple M5 hex bolts 103. The lamp cover 102 is provided on the front of the lamp body 101. The light source module is provided inside the lamp body 101, and the illumination end of the light source module corresponds to the lamp cover 102. The lamp body 101 has continuous gradient curved surfaces in the X-axis, Y-axis and Z-axis directions. The X-axis is the length direction, the Y-axis is the width direction and the Z-axis is the height direction. The gradient curved surface of the X-axis has a wavy arc along the length direction of the lamp, the gradient curved surface of the Y-axis is convex along the width direction of the lamp and matches the front profile of the rail vehicle, and the gradient curved surface of the Z-axis has a spiral twist structure in the vertical direction of the lamp body 101.

[0019] In this embodiment, the lamp body 101 is provided with continuous gradient curved surfaces in the X-axis, Y-axis and Z-axis directions: the wavy arc of the X-axis enhances the fit with the front of the rail vehicle, the convex curved surface of the Y-axis directly matches the external contour of the front of the rail vehicle, and the spiral torsion structure of the Z-axis compensates for the difference in the vertical mounting surface. The lamp body 101 with the above-mentioned three-dimensional curved surfaces can fit tightly with the complex streamline of the front of the vehicle without additional brackets or shims. During installation, it only needs to be fixed by the M5 hexagonal bolts 103. The assembly process is convenient, and since no additional brackets or shims are required during installation, the installation cost of the entire indicator light is reduced.

[0020] Furthermore, the lamp body 101 is 3D printed using photocurable resin or nylon material, and the lampshade 102 is a flat acrylic sheet, which is bonded and fixed to the end face of the lamp body 101.

[0021] Furthermore, a wiring terminal 104 is provided on the back of the lamp body 101. One end of the wiring terminal 104 is connected to the light source module, and the other end of the wiring terminal 104 is connected to an external cable.

[0022] In this embodiment, by integrating the wiring terminal 104 on the back of the lamp body 101, a fast and reliable connection between the light source module and the external cable is achieved.

[0023] Furthermore, the light source module includes a flexible circuit board 105 and a surface-mount LED strip 106. The flexible circuit board 105 is installed inside the lamp body 101 and is located on the side of the lamp body 101 away from the lamp cover 102. The side of the flexible circuit board 105 away from the lamp cover 102 is connected to the terminal block 104, and the surface-mount LED strip 106 is provided on the side of the flexible circuit board 105 close to the lamp cover 102.

[0024] In this embodiment, the flexible circuit board 105 is mounted close to the inner curved surface of the lamp body 101, perfectly fitting the multi-curved structure and avoiding the assembly stress caused by the shape limitation of traditional rigid PCBs. The surface-mount LED strip 106 is evenly arranged on the side of the flexible circuit board 105 facing the lamp cover 102, and the uniformity of light output is ensured through the conformal layout of the curved surfaces.

[0025] Furthermore, the surface-mount LED light strip 106 is uniformly provided with a plurality of LED light bead units, each of which consists of a first light bead 107 (white) and a second light bead 108 (red) arranged side by side, and the first light bead 107 and the second light bead 108 of each two adjacent LED light bead units are arranged in an alternating structure.

[0026] In this embodiment, each LED lamp unit integrates red and white dual-color lamp beads, which are arranged side by side to ensure independent control; adjacent units adopt a red and white lamp bead staggered arrangement structure to achieve the best distribution density of the two colors in a limited space. The above structure enables a single lamp strip to achieve the dual functions of white light constant illumination and red light warning.

[0027] Furthermore, a mesh-type heat dissipation structure 109 is provided on the side of the lamp body 101 away from the lamp cover 102, and the flexible circuit board 105 is installed on the mesh-type heat dissipation structure 109.

[0028] In this embodiment, the mesh heat dissipation structure 109 is directly integrated into the inner curved surface of the lamp body 101 and is closely attached to the flexible circuit board 105 to form a three-dimensional heat dissipation channel, thereby dissipating the heat generated by the operation of the flexible circuit board 105.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
