[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Please refer to Figure 1 and Figure 2The embodiment of the present invention provides an indirect connection structure between a roof 20 and a side wall 30, comprising: a connecting piece 10, a roof 20 and a side wall 30. The connecting piece 10, the roof 20 and the side wall 30 can all be made of carbon fiber composite pultruded profiles. A support plate 11 extending toward the roof 20 is provided on the inner side of the upper portion of the connecting piece 10. The lower portion of the roof 20 is connected to the support plate 11, that is, the support plate 11 can bear the load of the roof 20. The support plate 11 can extend obliquely upward. The upper end surface of the connecting piece 10 and the support plate 11 form a V-shaped groove, and the lower end surface of the roof 20 and the inner side surface of the roof 20 form a V-shaped structure placed in the V-shaped groove; the inner side of the lower portion of the connecting piece 10 is provided with a first inner The connecting plate 12 and the outer side of the lower part of the connecting member 10 are provided with a first external connecting plate 13 extending toward the side wall 30. The first internal connecting plate 12 and the first external connecting plate 13 as well as the support plate 11 and the main body structure of the connecting member 10 are preferably an integrally formed structure. The inner side of the upper part of the side wall 30 is provided with a second internal connecting plate 31. The second internal connecting plate 31 and the side wall 30 are also preferably an integrally formed structure. The first internal connecting plate 12 is connected to the second internal connecting plate 31, for example, by riveting. The first external connecting plate 13 is connected to the outer side surface of the upper part of the side wall 30, and the connection between the two can also be riveted. After the first external connecting plate 13 is riveted, the outer surface of the first external connecting plate 13 can be covered by a first cover plate to shield the rivets. The use of the connector 10 as an intermediate connecting structure can effectively reduce the manufacturing difficulty of the roof 20 and the side wall 30. In addition, the connection between the first inner connecting plate 12 and the second inner connecting plate 31, as well as the connection between the first outer connecting plate 13 and the side wall 30, can effectively improve the connection stability between the connector 10 and the side wall 30. In addition, the support plate 11 can effectively position the roof 20 and facilitate the connection of the roof 20, thereby effectively improving the connection stability of the connector 10 and the roof 20, thereby ensuring the assembly stability of the roof 20 and the side wall 30.

[0032] In some embodiments, the outer side of the roof 20 is provided with a second external plate 21 extending toward the connector 10. The second external plate 21 and the roof 20 are preferably integrally formed. The second external plate 21 is connected to the outer side of the upper portion of the connector 10. The second external plate 21 can be riveted to the outer side of the connector, and then a second cover plate is provided on the outer side of the second external plate 21 to cover the rivets. The second external plate 21 is preferably a curved surface structure, and accordingly, the outer side of the upper portion of the connector 10 is also a curved surface. In addition, the first external plate 13 is also preferably a curved surface structure, and accordingly, the outer side of the upper portion of the side wall 30 is also a curved surface. The outer and inner sides of the connector 10 are both curved surfaces, and the connector 10 is located at the corner of the roof 20 and the side wall 30. The second external plate 21 can further improve the connection stability between the roof 20 and the connector 10.

[0033] In some embodiments, a gap is left between the upper end surface of the connector 10 and the lower end surface of the roof 20. This gap allows the position of the roof 20 to be adjusted, thereby facilitating the assembly of the roof 20. The gap is filled with sealant to improve the airtightness of the vehicle body.

[0034] In some embodiments, a first groove is provided on the outer side surface of the upper portion of the side wall 30, into which the first external plate 13 is connected. The provision of the first groove ensures a smooth transition between the outer sides of the side wall 30 and the first external plate 13 after the first external plate 13 is connected to the side wall 30. A second groove is provided on the outer side surface of the upper portion of the connector 10, into which the second external plate 21 is connected. The provision of the second groove ensures a smooth transition between the outer sides of the roof 20 and the second external plate 21 after the second external plate 21 is connected to the connector 10. The first external plate 13 can be riveted into the first groove using multiple rows of rivets, and the second external plate 21 can also be riveted into the second groove using multiple rows of rivets.

[0035] In some embodiments, the lower end surface of the connector 10 is flush with the lower surface of the first internal connecting plate 12, and the upper end surface of the side wall 30 is flush with the upper surface of the second internal connecting plate 31. When the connector 10 is placed on the upper part of the side wall 30, the first internal connecting plate 12 and the second internal connecting plate 31 are in surface contact, which can increase the connection area between the connector 10 and the side wall 30, thereby improving the stability of the connection.

[0036] In some embodiments, as Figure 1 and Figure 3 As shown, the indirect connection structure between the roof 20 and the side wall 30 also includes an air-conditioning platform 40. One side of the air-conditioning platform 40 is connected to the upper part of the connecting member 10. For example, a V-shaped protrusion structure that is engaged in the V-shaped groove on the connecting member 10 can be provided at the lower part of one side of the air-conditioning platform 40. The upper part of this side of the air-conditioning platform 40 is fixedly connected to the lower part of the roof 20, that is, the lower part of the roof 20 can be directly connected to the connecting member 10 when the air-conditioning platform 40 is not provided. When the air-conditioning platform 40 is provided at the lower part of the roof 20, it is connected to the connecting member 10 through the air-conditioning platform 40. The main structure of the air-conditioning platform 40 is located inside the vehicle body.

[0037] Please refer to Figures 1 to 3The present invention also provides a vehicle body comprising the indirect connection structure between the roof 20 and the side wall 30 provided in any of the aforementioned embodiments, and further comprising a chassis, with a side wall 30 mounted on each side of the chassis. Each side wall 30 is equipped with a connector 10, one of which can be directly connected to the lower portion of one side of the roof 20, and the other connector 10 can be connected to the air conditioning platform 40, which is in turn connected to the other side of the roof 20. The beneficial effects of the vehicle body can be seen in the indirect connection structure between the roof 20 and the side wall 30 provided in the aforementioned embodiments, and will not be further described here.

[0038] An embodiment of the present invention also provides a rail vehicle, comprising the vehicle body provided in the above embodiment, and also comprising a driving device, the driving device being used to drive the vehicle body to move. For the beneficial effects of the rail vehicle, reference may be made to the indirect connection structure between the roof 20 and the side wall 30 provided in the above embodiment, which will not be repeated here.
