[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0039] The core of the present invention is to provide a console for a rail vehicle and its manufacturing and forming method, which can effectively reduce the complexity of the production and assembly process, improve the loading efficiency, and achieve the reliability of product quality.

[0040] In order to enable those skilled in the art to better understand the technical solutions provided by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Specifically, please refer to Figures 1 - 6 , a console S for a rail vehicle provided by the present invention includes a visor 100.

[0042] The visor 100 includes a first connecting plate 110, a second connecting plate 120, an adhesive layer 130, a connecting component, and a composite material layer 150.

[0043] The first connecting plate 110 and the second connecting plate 120 partially overlap and lap, and connection holes are provided at the relative positions of the overlapping parts of the first connecting plate 110 and the second connecting plate 120. The adhesive layer 130 is disposed between the mutually overlapping surfaces of the first connecting plate 110 and the second connecting plate 120. The upper surfaces of the first connecting plate 110 and the second connecting plate 120 form a U-shaped groove.

[0044] The connecting component passes through the first connecting plate 110 and the second connecting plate 120 through the connection holes, so that the first connecting plate 110 and the second connecting plate 120 are firmly connected. Of course, when the connection holes on the first connecting plate 110 and the second connecting plate 120 overlap with the adhesive layer 130, the connecting component passes through the first connecting plate 110, the adhesive layer 130, and the second connecting plate 120 through the connection holes.

[0045] The composite material layer 150 covers the U-shaped groove inside the first connecting plate 110 and the second connecting plate 120.

[0046] A console S for rail vehicles provided by this solution uses an adhesive layer to bond the overlapping surfaces between the first connecting plate 110 and the second connecting plate 120 to achieve pre-connection. Then, a connecting component is used to tightly connect the two through connecting holes opened at the relative positions of the overlapping and lapping parts of the first connecting plate 110 and the second connecting plate 120. Finally, a composite material layer 150 is laid in the U-shaped grooves on the outer surfaces of the first connecting plate 110 and the second connecting plate 120. Compared with the process methods in the prior art, this solution combines three connection forms: adhesion, locking, and coating, which are redundant to each other. The connection joint has high strength, is less affected by manual operation, can effectively reduce the complexity of the production and assembly processes, improve the vehicle loading efficiency, and achieve the reliability of product quality.

[0047] In a specific embodiment, the connecting component includes a countersunk rivet 140 and a gasket 160. Of course, a structural combination such as bolts, nuts, or other fasteners can also be used to achieve the above functions.

[0048] Furthermore, the riveting surface of the countersunk rivet 140 faces the composite material layer 150.

[0049] During the riveting process, the rivet passes through the connecting holes of the first connecting plate 110 and the second connecting plate 120, and under the action of a riveting gun, one end of the rivet will deform to form a new rivet head, thereby tightly connecting the first connecting plate 110 and the second connecting plate 120 together. The surface where this newly formed rivet head is located can be called the "riveting surface". After the composite material layer 150 is laid on the riveting surface of the countersunk rivet 140, the stability of the connection can be further improved.

[0050] In a specific embodiment, the first connecting plate 110 and the second connecting plate 120 can be made of metal materials, and the composite material layer 150 can be a composite material. Using new composite materials instead of traditional metal materials is an important way to lightweight vehicles.

[0051] Specifically, the composite material layer 150 can specifically be made of fiberglass or carbon fiber. Fiberglass is a material composed of glass fibers and a resin matrix, with the characteristics of light weight, high strength, corrosion resistance, strong designability, and good insulation. Carbon fiber is a microcrystalline graphite material obtained by stacking organic fibers such as sheet-like graphite microcrystals along the fiber axial direction and undergoing carbonization and graphitization treatments, with the characteristics of corrosion resistance and high modulus.

[0052] Using the above fiberglass or carbon fiber composite materials has mechanical properties such as high strength, high modulus, high specific strength, and high specific modulus, enabling the fiberglass or carbon fiber composite materials to achieve vehicle lightweighting without reducing the overall mechanical performance of the vehicle, and being able to provide sufficient structural strength for the cab visor to meet various force requirements during use, such as resisting external impact forces, etc.

[0053] As shown Figure 3 in the figure, both the first connecting plate 110 and the second connecting plate 120 are Z-shaped bent plates. The Z-shaped bent plate includes a first end plate located above, a second end plate located below, and an intermediate plate connecting the first end plate and the second end plate.

[0054] The second end plates in the first connecting plate 110 and the second connecting plate 120 are overlapped with each other. Further, the lengths of the second end plates of the first connecting plate 110 and the second connecting plate 120 are equal. With such a setting, it is convenient to connect the first connecting plate 110 and the second connecting plate 120 without increasing the thickness of the plate, and at the same time, there is a space for laying the composite material layer 150 above the two.

[0055] A U-shaped groove for laying the composite material layer 150 is formed between the outer surfaces of the first connecting plate 110 and the second connecting plate 120.

[0056] Specifically, in order to increase the coverage area of the composite material layer 150, the edges of the U-shaped groove extend to the first end plates of the first connecting plate 110 and the second connecting plate 120. The cross-section of the cured composite material layer 150 in the U-shaped groove is T-shaped.

[0057] Before the adhesive layer 130 is completely cured, the connecting component passes through the first connecting plate 110, the adhesive layer 130 and the second connecting plate 120 through the connecting holes, so as to prevent the connecting component from penetrating the adhesive layer 130 and affecting the mechanical properties of the adhesive layer 130.

[0058] Of course, the console S of the rail vehicle in this case further includes a main body 200 and a bottom plate 300. The brim 100, the main body 200 and the bottom plate 300 are connected in sequence from top to bottom.

[0059] In addition, the present invention also provides a manufacturing and forming method for the console of a rail vehicle, which is used to prepare the brim 100 of the console S of the rail vehicle, and includes the following steps:

[0060] Pre-fixing, connecting the first connecting plate 110 and the second connecting plate 120 with glue.

[0061] Tight connection, before the glue cures naturally for a preset time and is not completely cured, connecting the first connecting plate 110 and the second connecting plate 120 with a connecting component until the glue is completely cured to form the adhesive layer 130.

[0062] Laying the composite material layer, laying the composite material layer 150 on the outer sides of the first connecting plate 110 and the second connecting plate 120 to cover the connection part between the two, and heating and curing at a preset temperature to form the composite material layer 150.

[0063] It should be noted that before the adhesive layer 130 is completely cured, riveting the first connecting plate 110 and the second connecting plate 120 in a state where the glue still has a certain fluidity can reduce the assembly error generated when the first connecting plate 110 and the second connecting plate 120 are butted through the glue. At the same time, the connection assembly combined with the glue connection further improves the connection strength.

[0064] This solution combines three connection forms: adhesion, locking, and coating, which are redundant to each other. The connection joint has high strength, is less affected by human operation, can effectively reduce the complexity of the production and assembly process, improve the loading efficiency, and the product quality is high and stable.

[0065] In a specific embodiment, the process of connecting the first connecting plate 110 and the second connecting plate 120 with glue can be naturally dried at room temperature.

[0066] In a specific embodiment, the connection assembly includes a countersunk head rivet 140 and a gasket 160. In the fastening connection step, the countersunk head rivet 140 and the gasket 160 are used for blind riveting connection.

[0067] In the fastening connection step, before the glue is naturally cured for a preset time and not completely cured, the first connecting plate 110 and the second connecting plate 120 are connected by the connection assembly, and then placed at room temperature until the glue is completely cured. This preset time can be adaptively selected according to actual needs, such as 10 min - 20 min, and the glue is in a state of being to be cured but not completely cured.

[0068] In the step of laying the composite material layer, the outer sides of the first connecting plate 110 and the second connecting plate 120 are plastered and formed with a fiber cloth to form a composite material layer 150. The advantage of using a fiber cloth for plastering and forming is that the design and construction of the used mold are simple, the production cost is low, a high fiber content can be achieved, which helps to improve the mechanical properties of the composite material, and different geometric shapes and complex structures can be used.

[0069] In the step of laying the composite material layer, after laying the composite material layer 150, it is heated and cured in a curing furnace at a preset temperature. The preset temperature can be adaptively selected according to actual needs, such as 40°C - 50°C.

[0070] In a specific embodiment, the first connecting plate 110 and the second connecting plate 120 are adhesively bonded with glue under normal temperature conditions to achieve pre-fixation. After the glue is naturally cured for 15 minutes, the glue is not completely cured. A countersunk rivet 140 and a metal gasket 160 matching the rivet are used for blind riveting connection. Then, it is placed at normal temperature for 30 minutes until the glue is completely cured. A fiber cloth is laid and pasted on one side of the blind riveting surface to form a composite material layer 150. Then, it is heated and cured in a curing furnace at 45°C for 2 hours, and finally the brim 100 of the console S of the rail vehicle in this solution is manufactured.
