[0028] The following is in conjunction with the appendix Figures 1-10 This invention further illustrates a specific implementation of a carbon fiber skirt structure, overcoming the limitations of existing urban rail vehicles that mostly employ integrated alloy structures. While these skirts offer high overall strength, their weight is also relatively large, resulting in a heavy load on the urban rail vehicle. Furthermore, existing skirt structures suffer from deficiencies in their installation design. In this invention, the carbon fiber beams, when installed on the edge of the skirt body via hinges, exhibit greater stability at their connection points, ensuring installation stability and effectively preventing loosening of the carbon fiber beams over long-term use. Moreover, the clamping effect of the outer groove pads further enhances the connection strength of the carbon fiber beams. This invention's carbon fiber skirt structure is not limited to the description in the following embodiments.

[0029] Example 1

[0030] This embodiment provides a carbon fiber skirt structure, such as Figures 1-3 As shown, the skirt panel includes a main body, which includes an upper plate 3 and a lower plate 2. Both the upper plate 3 and the lower plate 2 are made of carbon fiber plates. The upper plate 3 and the lower plate 2 are integrally formed or welded together. A carbon fiber beam 13 is rotatably installed on the top of the skirt panel through a hinge 1. A profile groove 6 is opened at the lower opening of the carbon fiber beam 13 at the position of the hinge 1. A screw 7 is installed in the profile groove 6. The screw 7 passes through the hinge 1 to fix the carbon fiber beam 13 to the hinge 1. The top of the skirt panel is connected to the other side of the hinge 1 through the screw 7.

[0031] The profile groove 6 has an inner groove pad 14 inside, the cross section of which is Y-shaped. The profile groove 6 has an outer groove pad 8 outside. The screw 7 passes through the inner groove pad 14 and the outer groove pad 8. The inner groove pad 14 is elastic.

[0032] Specifically, in order to further improve the connection stability of the carbon fiber beam 13, in this embodiment, the part connecting the hinge 1 to the main body of the skirt plate adopts a straight strip structure, and the part connecting the hinge 1 to the carbon fiber beam 13 adopts a continuous three-segment bending structure. The end segment and the middle segment of the bending structure have an included angle ∠α, and the value of ∠α is 95°. This structural setting allows the carbon fiber beam 13 to be fixed to different planes at the bottom when connected to the hinge 1, thereby making the fixing more stable.

[0033] By adopting the above technical solution:

[0034] When the carbon fiber beam 13 in the carbon fiber skirt is installed on the edge of the skirt body by the hinge 1, the stability of its connection position is higher, thereby ensuring the installation stability of the carbon fiber beam 13 and effectively avoiding the loosening of the carbon fiber beam 13 after long-term use. Furthermore, the connection strength of the carbon fiber beam 13 can be further improved by the inner and outer clamping effect of the groove pad 8.

[0035] Example 2

[0036] Based on Example 1, in this example, in order to make the overall outer surface of the carbon fiber skirt panel smoother and reduce wind resistance during application, the outer edges of the skirt panel body are all rounded, and the angle of the rounded corner of the edge section of the skirt panel body is set to R. The thickness of the skirt panel body and the lower plate 2 is set to D. Then, the value of R is: 1 / 3D≤R≤1 / 2D.

[0037] Specifically, such as Figure 1 and Figure 6 As shown, in order to facilitate the subsequent installation of the entire skirt panel, in this embodiment, the edge of the main body of the skirt panel is provided with a frame profile 15, and multiple reserved installation components 16 are provided at equal intervals at the bottom position of the frame profile 15. The connection position between the frame profile 15 and the reserved installation components 16 and the cross-section of the reserved installation components 16 are both C-shaped that can be adapted to each other, so that the two end faces of the frame profile 15 and the reserved installation components 16 are welded together. Furthermore, a strip-shaped cavity is opened at the connection position between the frame profile 15 and the reserved installation components 16, and the cavity is filled with rubber 11.

[0038] Specifically, such as Figure 1 and Figure 9 As shown, in order to reduce the weight of the skirt panel as much as possible while ensuring the strength of the entire skirt panel body and to achieve lightweighting, in this embodiment, the space between the upper plate 3 and the lower plate 2 is filled with an aluminum honeycomb plate 4. This can both ensure the strength of the skirt panel body and reduce its weight. In addition, the edges of the upper plate 3 and the lower plate 2 are coated with a layer of sealant, thereby increasing the overall consistency and sealing of the skirt panel body.

[0039] Specifically, such as Figure 1 and Figure 7 , Figure 8 As shown, in order to reserve the installation structure of the lock, in this embodiment, the surface of the lower plate 2 is welded with a first lock mounting seat 9 and a second lock mounting seat 10. Both the first lock mounting seat 9 and the second lock mounting seat 10 adopt a U-shaped structure. The vertical end length of the first lock mounting seat 9 is less than the vertical end length of the second lock mounting seat 10, which is convenient for accommodating the installation of different types of locks.
