[0046] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0047] See Figures 1-3 As shown in the figure, this application embodiment provides an installation structure for the undercarriage of a high-speed train, the installation structure including:

[0048] Main vertical panel 1 of rectangular plate structure;

[0049] A first horizontal plate 2 is disposed on the upper edge of the main body upright plate 1. The first horizontal plate 2 is located on one side of the main body upright plate 1 and is perpendicular to the main body upright plate 1.

[0050] The first connecting plate 3 has a set of symmetrical sides that are respectively connected to the first horizontal plate 2 and the main body upright plate 1;

[0051] The main upright plate 1 and the first connecting plate 3 are respectively connected to a set of symmetrical sides of the first horizontal plate 2;

[0052] Both the first horizontal plate 2 and the first connecting plate 3 are long rectangular plates;

[0053] The space surrounded by the main upright plate 1, the first horizontal plate 2, and the first connecting plate 3 is a right-angled triangular prism-shaped cavity.

[0057] The first horizontal plate 2, the first connecting plate 3, and the lifting box strip mounting groove 4 are all located on the same surface of the main body upright plate 1, and the length directions of the three are parallel.

[0058] In this embodiment, a triangular stabilizing structure is used to effectively improve the overall structural strength of the installation structure.

[0059] Furthermore, the number of the first bolt mounting through holes 20 and the number of the first installation process through holes 30 are the same and correspond one-to-one.

[0060] Furthermore, the projection of the line connecting the center point of the first bolt mounting through hole 20 and the center point of the first installation process through hole 30 onto the main body upright plate 1 is perpendicular to the length direction of the first horizontal plate 2.

[0061] For better display, the accompanying diagrams in the instruction manual are shown. Figure 1 Region A in the middle, through the attached Figure 2 A detailed demonstration will be provided.

[0062] Furthermore, the lifting box strip mounting groove 4 includes:

[0063] Two mutually spaced and parallel mounting strip structures 40;

[0064] The mounting strip structure 40 is a strip plate with an L-shaped cross-section.

[0065] Furthermore, the main upright plate 1, the first horizontal plate 2, and the first connecting plate 3 are integrally formed.

[0066] It should be noted that in the technical solutions of the embodiments of this application:

[0067] The installation interface, namely the structure composed of the main upright plate 1, the first horizontal plate 2 and the first connecting plate 3, is a stable structure extruded from a triangular profile.

[0068] The first horizontal plate 2 is a mounting surface, which is provided with multiple first bolt mounting through holes 20 for mounting onto the vehicle body;

[0069] On the first connecting plate 3 corresponding to the long side of the triangular profile section, a first installation process through hole 30 is machined perpendicular to the plate surface to fasten the bolt in the first bolt installation through hole 20.

[0070] The installation structure for the undercarriage of a high-speed train provided in this application embodiment can be extruded together with the body facade. The body facade can be integrated with or welded with C-shaped grooves, or it can be extruded separately with triangular profile installation structure as a universal interface, and then welded to the undercarriage facade in the form of a butt joint. Compared with the traditional T-joint weld, the fatigue resistance of the butt joint weld is second only to the base material.

[0071] In summary, the technical solutions of the embodiments of this application have the following beneficial effects:

[0072] 1. The integrated extrusion molding of the profiles reinforces the structure, reducing complex welding processes and resulting in better economic benefits.

[0073] 2. The base material structure has better fatigue resistance than the welded structure.

[0074] 3. The profile cross-section adopts a triangular stable structure, which provides high strength at the box hoisting position and allows for the use of fewer bolts for fastening.

[0075] 4. The installation process holes are made perpendicular to the plate surface, which improves the processability.
