[0020] In order to make the technical means, creative features, achieved objectives and functions of the utility model clearer and easier to understand, the technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figures 1 to 3As shown in the figure, an overhead side structure of a track includes: a first connecting section 1, a second connecting section 2, and a third connecting member 3 connected to the vehicle body; the first connecting section 1 is connected to the second connecting section 2, and the included angle between the first connecting section 1 and the second connecting section 2 is an obtuse angle, and the side of the second connecting section 2 away from the first connecting section 1 is rotatably connected to the third connecting member 3; a first reinforcing rib 11 is arranged on the first connecting section 1 along the length direction of the first connecting section 1, a reinforcing plate 12 is arranged on the first connecting section 1, and the reinforcing plate 12 is fixedly connected to the side of the first reinforcing rib 11 away from the second connecting section 2; a rectangular opening is arranged in the middle of the second connecting section 2, and second reinforcing ribs 21 are respectively arranged at both ends of the rectangular opening on the second connecting section 2, and a first reinforcing strip 22 is fixedly connected between several second reinforcing ribs 21 at the same end of the rectangular opening, and second reinforcing strips 4 are arranged on both sides of the rectangular opening at the bottom of the second connecting section 2.

[0022] The first connecting section 1 of the overhead side plate is integrally formed with the second connecting section 2, and the included angle between the first connecting section 1 and the second connecting section 2 is an obtuse angle, which is convenient for installing it on the overhead side of the vehicle and reducing the occupied space; the third connecting member 3 is connected to the vehicle body. When the first connecting section 1 is also connected to the vehicle body, some equipment is located between the back of the overhead side plate and the vehicle body. When the connection between the first connecting section 1 and the vehicle body is released, the second connecting section 2 and the third connecting member 3 can rotate relative to each other, which is convenient for opening the overhead side plate and performing maintenance on the equipment on the overhead side plate; the first reinforcing rib 11 is arranged on the first connecting section 1, and the second reinforcing rib 21 is arranged on the second connecting section 2, which can play a role in supporting and increasing the strength of the overhead side plate, and a first reinforcing strip 22 is connected between several second reinforcing ribs 21, so that the strength of the second connecting section 2 is increased; the second reinforcing strip 4 is arranged at the bottom of the second connecting section 2 and on both sides of the rectangular opening, so that the strength on both sides of the rectangular opening is increased. A reinforcing plate 12 is arranged on one side of the first reinforcing rib 11 to increase the connection strength between the first reinforcing rib 11 and the first connecting section 1, so that the strength of the overhead side plate is further increased to meet the requirements.

[0023] Further, as Figure 1 shown, a lapping edge 13 is arranged on the side of the first connecting section 1 away from the second connecting section 2. On the one hand, the lapping edge 13 can play a role in covering the gap between the overhead side plate and the vehicle body, further improving the aesthetics inside the vehicle body. On the other hand, it can also improve the strength at the edge of the overhead side plate and reduce the deformation amount at the edge of the overhead side plate.

[0024] Further, as Figure 1Shown is the specific structure of the first reinforcing rib 11 and the second reinforcing rib 21. Both the first reinforcing rib 11 and the second reinforcing rib 21 include two connecting plates arranged parallel to each other, and a transverse plate portion is provided on one side where the tops of the two connecting plates are close to each other. An installation groove is formed between the first reinforcing rib 11 and the first connecting section 1, and between the second reinforcing rib 21 and the second connecting section 2. This enables the first reinforcing rib 11 and the second reinforcing rib 21 not only to increase the strength of the side top plate, but also to be used for assembling components, such as gas springs, noise detectors, etc.

[0025] Further, as Figure 1 and Figure 2 shown, the third connecting member 3 includes a main connecting vertical plate 31. A top plate 32 is vertically connected to the top of the main connecting vertical plate 31, and an inclined plate is connected to the bottom end. The inclined plate is connected to a first circular arc concave plate 33. An upward arc-shaped curl is provided on the side of the second connecting section 2 away from the first connecting section 1. The arc-shaped curl includes a second circular arc concave plate 23. The second circular arc concave plate 23 rotates within the first circular arc concave plate 33. Two notches are provided at intervals along the length direction of the second connecting section 2 on the arc-shaped curl. A protruding portion that can extend out of the notch is provided on the side of the first circular arc concave plate 33. The top plate 32 is used to connect with the vehicle body. The second circular arc concave plate 23 and the first circular arc concave plate 33 are coaxially arranged. The second circular arc concave plate 23 can rotate within the first circular arc concave plate 33 along the axis of the second circular arc concave plate 23. The cooperation between the protruding portion and the notch can limit the rotation of the side top plate and prevent it from disengaging from the end of the first circular arc concave plate 33.

[0026] Further, in order to increase the reliability and stability of the connection with the vehicle body, a side connecting plate 311 is provided on the side of the main connecting vertical plate 31, and the upper end of the side connecting plate 311 is connected to the side of the top plate 32.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
