Description

Technical Field

[0001] This utility model relates to the field of rail vehicle components, and in particular to a composite luggage rack for high-speed trains. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, high-speed rail, as an efficient and convenient mode of transportation, has become an important choice for people's travel. In particular, the popularization of high-speed trains has driven a large flow of passengers. However, with the increase in passenger flow, the problem of luggage storage in trains has gradually become prominent. To address this, luggage racks for placing passengers' luggage are set up at both ends of the train. However, the luggage racks in the interior partitions of high-speed trains are usually made of metal or composite materials. During long-term use, the surface is easily affected by wear, scratches and corrosion, resulting in a decline in aesthetics and functionality.

[0003] Therefore, a luggage rack that is both aesthetically pleasing and durable, capable of high-frequency use and harsh environments, is proposed to meet the special needs of high-speed trains. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a composite luggage rack for high-speed trains. Through multi-layer surface treatment, the durability, aesthetics, and environmental friendliness of the interior partition luggage rack for high-speed trains are improved.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A composite luggage rack for high-speed trains includes a luggage frame. Multiple mounting slots are formed on the inner walls of both sides of the luggage frame. Multiple supporting frames slide within each mounting slot. Multiple supporting shafts are fixedly connected to the inner walls of the supporting frames. A composite coating is applied to the outer walls of both the supporting frames and the supporting shafts. The composite coating includes a corrosion-resistant treatment layer that adheres to the outer wall of the supporting frame. A high-hardness ceramic coating is sprayed onto the outer wall of the corrosion-resistant treatment layer, and a nano-antibacterial coating is sprayed onto the outer wall of the high-hardness ceramic coating.

[0007] The above technical solutions solve the problems of easy wear, poor corrosion resistance and insufficient environmental protection in traditional surface treatment methods, and improve the durability, appearance and environmental performance of vehicle interior trim components.

[0008] Furthermore, fixing holes are provided at the front and rear ends of the inner walls on both sides of the supporting frame, and the supporting frame is fixed to the inside of the mounting groove by bolts passing through the fixing holes;

[0009] The above technical solution allows staff to better adjust the position of the supporting frame according to their needs.

[0010] Furthermore, the nano-antibacterial coating is made of nanoparticle material;

[0011] The above technical solution uses a nano-antibacterial coating to treat the supporting frame, ensuring that the luggage rack and partition surfaces are clean and easy to maintain.

[0012] Furthermore, the high-hardness ceramic coating is made of ceramic particles;

[0013] The above technical solution enhances the surface's wear resistance, hardness, and durability by using ceramic nanomaterial coating.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a composite luggage rack for high-speed trains. In tests simulating the environment of high-speed trains, the luggage rack with this composite coating showed significant improvements in service life and surface performance. Experimental data showed that the treated surface exhibited a 50% increase in wear resistance and a 30% increase in corrosion resistance in wear resistance tests. Furthermore, in antibacterial tests simulating long-term use, the antibacterial effect remained above 99%, and the anti-fingerprint effect was significant. This improved the durability, aesthetics, and environmental friendliness of the luggage rack in the interior partitions of high-speed trains. The high-hardness ceramic coating and anti-corrosion treatment ensured its durability in harsh environments, while the antibacterial coating increased the hygiene of the interior environment and reduced maintenance costs. The surface treatment process is environmentally friendly and energy-saving, suitable for mass production, and simple to maintain, showing good prospects for widespread application.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] One embodiment of this utility model is provided:

[0026] A composite luggage rack for high-speed trains includes a luggage frame 1. Multiple mounting slots 3 are provided on the inner walls of both sides of the luggage frame 1. Multiple support frames 2 slide inside the mounting slots 3. Multiple support shafts 4 are fixedly connected to the inner walls of the support frames 2. The outer walls of the support frames 2 and the support shafts 4 are provided with a composite coating 5. The composite coating 5 includes a corrosion-resistant treatment layer 503 that is attached to the outer wall of the support frame 2. The outer wall of the corrosion-resistant treatment layer 503 is sprayed with a high-hardness ceramic coating 502. The outer wall of the high-hardness ceramic coating 502 is sprayed with a nano antibacterial coating 501.

[0027] It solves the problems of easy wear, poor corrosion resistance and insufficient environmental protection in traditional surface treatment methods, and improves the durability, appearance and environmental performance of vehicle interior trim parts.

[0028] Fixing holes 6 are provided at the front and rear ends of the inner walls on both sides of the support frame 2. The support frame 2 is fixed to the inside of the mounting groove 3 by bolts passing through the fixing holes 6, so that the position of the support frame 2 can be adjusted by the staff according to the needs. The nano antibacterial coating 501 is made of nanoparticle material. By applying the nano antibacterial coating 501 to the support frame 2 for antibacterial and anti-fingerprint treatment, it is ensured that the luggage rack and partition surface is clean and easy to maintain. The high-hardness ceramic coating 502 is made of ceramic particles. By using ceramic nanomaterials for coating, the wear resistance of the surface is enhanced, and the hardness and durability are improved.

[0029] Working Principle: The luggage frame 1 is installed in the original luggage rack position inside the train. Multiple support frames 2 are then fixed inside the luggage frame 1 using bolts inserted into the fixing holes. A corrosion-resistant layer 503, formed by chemical nickel plating during manufacturing, effectively prevents oxidation or corrosion in humid environments. A high-hardness ceramic coating 502 is then sprayed onto the corrosion-resistant layer 503. The ceramic particles are cured at high temperatures to form a high-hardness protective layer, improving surface wear resistance and making the support frames 2 less prone to scratches during long-term use. A nano-antibacterial coating 501 effectively kills bacteria and prevents fingerprint residue, keeping the surface of the support frames 2 clean. The antibacterial components of the nanoparticles do not lose their effectiveness during cleaning, ensuring a long-lasting antibacterial effect. Thus, through a multi-layer surface treatment process combined with nano-... Antibacterial coating 501, high-hardness ceramic coating 502, and corrosion-resistant treatment layer 503 are used to improve surface hardness, corrosion resistance, and antibacterial properties. When treating the corrosion-resistant treatment layer 503, firstly, prepare the metal parts to be nickel-plated and perform necessary cleaning and pretreatment to ensure that the surface is free of oil and impurities. Then, use the cleaned metal parts as cathodes and place them in an electrolyte containing nickel salts, conductive salts, pH buffers, and wetting agents. Use metallic nickel as the anode and apply direct current to reduce and deposit nickel ions on the cathode to form a uniform and dense nickel plating layer. By adjusting the composition of the electrolyte and the current density, plating layers with different brightness can be obtained. Then, the metal parts need to be cleaned and pretreated again. Finally, under specific conditions, an aqueous solution containing nickel ions is mixed with a reducing agent to reduce and deposit nickel ions on the surface of the metal parts to form a plating layer. No external current is required during the chemical nickel plating process.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
