Technical Field

[0001] This utility model relates to the technical field of rail transit, and in particular to a composite roof panel with lights for high-speed train vehicles. Background Technology

[0002] The existing rail vehicle roof panel generally uses a 1.5mm aluminum sheet stamped and integrated with 12 independent small lights, which has inherent defects: the density and thickness limitations of the aluminum sheet make it difficult to balance lightweight and structural strength; thinning results in insufficient rigidity and easy vibration deformation, while thickening results in excessive weight; the surface treatment layer of the aluminum sheet is prone to pitting corrosion in humid environments and has insufficient long-term corrosion resistance; independent installation of the lights requires additional brackets and exposed wiring, resulting in complex structure, increased weight, and risk of cable wear; the aluminum sheet is mixed with dissimilar materials such as metal inserts and coatings of the lights, making it difficult to separate and recycle efficiently, resulting in low recycling rate; the flat aluminum sheet has a monotonous shape, weak sound insulation and heat insulation performance, and cannot meet the requirements of modern rail vehicles for the integration of aesthetics and function.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0024] A composite roof panel with integrated lighting for high-speed train vehicles, such as Figures 1-4 As shown, it includes a top panel 1, a peripheral frame 2, a mounting bracket 3, and a lamp 6; the top panel 1 is fixed inside the peripheral frame 2, and the mounting bracket 3 is mounted on the peripheral frame 2; the lamp 6 is mounted on the back of the top panel 1 and forms a lantern-shaped area 6-1 on the front; the lantern-shaped area 6-1 is provided with a light-emitting aperture array 6-2, which consists of a number of light holes, and the size of the light holes in the light-emitting aperture array 6-2 gradually increases from both ends to the middle.

[0025] Specifically, the lantern-shaped area 6-1, combined with the light-emitting aperture array 6-2, creates a unique visual aesthetic. The aperture size of the light-emitting aperture array 6-2 gradually increases from both ends towards the center, precisely controlling the light distribution. This, along with the sequential emission of the light particles, creates a flowing display effect. The gradient aperture shape forms a visual rhythm, breaking away from the mechanical and rigid design of traditional small light arrays. The larger aperture in the center enhances the illumination of the core area, avoiding the central dark area defect of traditional uniform small apertures. The smaller apertures at both ends maintain uniform brightness at the edges, eliminating corner shadows and significantly improving the uniformity and comfort of lighting in the carriage. The light fixture 6 is built into the back of the central top panel 1, rigidly connected to the surrounding frame 2 using the mounting bracket 3, preventing vibration and abnormal noise, and improving structural stability.

[0026] As a preferred embodiment of the above, such as Figures 1-4As shown, the lamp 6 is provided with a hollow circular hole, and the light-emitting hole array 6-2 is symmetrically arranged around the hollow circular hole.

[0027] Specifically, the symmetrical gradient aperture array forms a ripple pattern around the central circular hole, enhancing the sense of visual order and further improving the aesthetic appeal of the flowing water display effect in conjunction with the light emission sequence of the lamp particles.

[0028] As a preferred embodiment of the above, such as Figures 1-4 As shown, a styling groove 1-1 is provided on the front side of the top panel 1. The styling groove 1-1 is composed of several parallel grooves. The grooves of the styling groove 1-1 avoid the area of ​​the light-emitting aperture array 6-2.

[0029] As a preferred embodiment of the above, such as Figures 1-4 As shown, the hollow circular hole on the front of the top panel 1 is also provided with the shaped groove 1-1. The shaped groove 1-1 is adapted to the shape of the hollow circular hole, and the shape of the shaped groove 1-1 outside the area of ​​the light-emitting hole array 6-2 is adapted to the shape of the shaped groove 1-1.

[0030] Specifically, the shaped groove 1-1, in conjunction with the light-emitting aperture array 6-2, creates a modern industrial aesthetic with the linear texture of the parallel groove and the optical rhythm of the gradient circular aperture, making the overall shape more aesthetically pleasing. On this basis, the groove forms a reinforcing rib effect on the surface of the top panel 1, solving the problem of vibration deformation of the top panel 1.

[0031] As a preferred embodiment of the above, such as Figures 1-4 As shown, the groove of the shaping groove 1-1 is provided with a number of ventilation shaping holes.

[0032] Specifically, the ventilation holes in the groove of the styling groove 1-1 not only provide decorative aesthetics but also form micro-airflow channels for ventilation, while retaining the reinforcing function of the groove 1-1.

[0033] As a preferred embodiment of the above, such as Figures 1-4 As shown, a lamp wiring groove 4 is also provided on the back of the top panel 1, and the lamp wiring groove 4 is used to guide the wiring of the lamp 6.

[0034] Specifically, the wiring channel 4 is formed in the mold on the back of the top panel 1, which precisely fits the wiring path of the lamp 6, eliminating the risk of wear and short circuit of traditional exposed cables and improving electrical safety.

[0035] As a preferred embodiment of the above, such as Figures 1-4 As shown, a transverse reinforcing rib 5 is also provided on the back of the top panel 1, which bears and distributes the weight of the lamp 6.

[0036] Specifically, the horizontal reinforcing rib 5 is used to specifically bear the concentrated load of the lamp 6, which improves the panel's resistance to deformation. The reinforcing rib and the front groove of the shaping groove 1-1 are staggered to avoid the superposition of the stamping weakened area, and the overall rigidity structure is further improved.

[0037] As a preferred embodiment of the above, such as Figures 1-4 As shown, the top panel 1 is made of thermoplastic composite material with a density design range of 100 kg / m³. 3 -550kg / m 3 The perimeter frame 2 is made of magnesium alloy profile, and the splicing joints are made of connecting plates and riveted together; the mounting bracket 3 is reinforced with reinforcing ribs welded in the middle.

[0038] Specifically, by using thermoplastic composite materials for the top panel 1, the sound insulation and heat preservation performance is optimized, while the weight is lighter than that of the traditional 1.5mm aluminum plate. The magnesium alloy profile frame further reduces the weight compared to the traditional aluminum material. The bonding and riveting process of the splicing plate eliminates welding deformation, improves fatigue strength, and ensures the long-term installation stability of the top panel 1.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
