[0029] Please refer to Figure 1 , Figure 1 Schematic diagram of a connection structure between a side wall and a roof provided by a specific embodiment of the present utility model.

[0030] The connection structure between a side wall 10 and a roof 20 provided by an embodiment of the present utility model is a connection structure between the side wall 10 and the roof 20 of a car body of a rail vehicle. The connection structure between the side wall 10 and the roof 20 includes: the side wall 10 and the roof 20, wherein the side wall 10 and the roof 20 can be made of a carbon fiber composite material. An inner support plate 11 is provided on the inner side of the upper end of the side wall 10, and the lower end of the roof 20 is lapped on the support plate 11. The support plate 11 is connected to the roof 20 through a first fastener 30. The support plate 11 extends upward, and the upward extension can be a vertical upward extension or an obliquely upward extension. The first fastener 30 can be selected as a rivet. After the lower end of the roof 20 is lapped on the support plate 11, it can be riveted through the rivet. An outer connecting plate 21 is provided on the outer side of the lower end of the roof 20. The inner side surface of the connecting plate 21 is in contact with the outer side surface of the side wall 10. The connecting plate 21 is connected to the side wall 10 through a second fastener 40. The connecting plate 21 extends downward, and the downward extension can be a vertical downward extension or an obliquely downward extension. The second fastener 40 can be selected as a rivet. After the connecting plate 21 of the roof 20 is lapped on the outer side surface of the side wall 10, it can be riveted through the rivet. By the mutual contact between the support plate 11 and the inner side surface of the lower end of the roof 20, and by the mutual contact between the connecting plate 21 and the outer side surface of the upper end of the side wall 10, the connection between the side wall 10 and the roof 20 can be a surface-to-surface contact relationship, and the roof 20 and the side wall 10 can be limited in position from both the inside and the outside directions. Therefore, the connection stability between the side wall 10 and the roof 20 can be effectively improved. In addition, through the connecting plate 21 on the outer side of the roof 20 and the support plate 11 on the inner side of the side wall 10, it is convenient to place the roof 20 on the side wall 10.

[0031] In some embodiments, a gap is left between the lower end surface 22 of the roof 20 and the upper end surface 12 of the side wall 10. Through this gap, the height position of the roof 20 can be adjusted. When the support plate 11 extends obliquely upward, adjustment in the width direction can also be achieved. Therefore, it is convenient to assemble the roof 20 and the side wall 10 through the gap. Among them, a sealant is filled in the space between the lower end surface 22 of the roof 20 and the upper end surface 12 of the side wall 10 to improve the airtightness of the car body.

[0032] In some embodiments, a groove is provided in the upper part of the outer side surface of the side wall 10. The connecting plate 21 is located in the groove. The thickness of the connecting plate 21 is preferably the same as the groove depth. Through the groove, not only can the connecting plate 21 be positioned, but also the connecting plate 21 can be prevented from protruding from the outer side surface of the side wall 10. Therefore, the flatness of the outer side surface after the connection between the side wall 10 and the roof 20 can be improved.

[0033] In some embodiments, a covering plate is provided on the outer side surface of the connecting plate 21. The covering plate can be fixed to the outer side surface of the connecting plate 21 by means of snap connection or bonding, etc. The covering plate can cover the second fastener 40 to ensure the flatness of the appearance at the connection position between the vehicle roof 20 and the side wall 10.

[0034] In some embodiments, the support plate 11 extends obliquely upward towards the vehicle roof 20. The support plate 11 is connected to the vehicle roof 20 by multiple rows of first fasteners 30. As Figure 1 shown, the support plate 11 extends towards the upper right direction, and the connecting plate 21 extends towards the lower left direction. When the vehicle roof 20 is placed on the side wall 10, the vehicle roof 20 can be restricted in two directions, namely the vertical direction and the horizontal direction, by the support plate 11. At the same time, the connecting plate 21 can also be restricted in two directions, namely the vertical direction and the horizontal direction, by the side wall 10. The inner side surface of the lower structure of the vehicle roof 20 can be selected as a planar structure to facilitate full contact with the support plate 11. In addition, the outer side surface of the lower structure of the vehicle roof 20 is an arc surface structure, and the outer side surface of the connecting plate 21 is also an arc surface structure accordingly. At this time, the outer side surface of the upper structure of the side wall 10 is also an arc surface structure accordingly to facilitate close cooperation with the connecting plate 21. When there is a groove on the outer side of the upper structure of the side wall 10, the surface corresponding to the connecting plate 21 in the groove is also an arc surface. In addition, in order to improve the structural strength at the corner of the vehicle roof 20, the thickness of the middle part of the downwardly curved corner section of the vehicle roof 20 is greater than the thickness of the two ends of the corner section.

[0035] In some embodiments, the upper end surface 12 of the side wall 10 is an inclined surface, and the included angle between the upper end surface 12 and the inner side surface of the side wall 10 is an obtuse angle. As Figure 1 shown, the inclined direction of the inclined surface is from the upper left to the lower right direction; the lower end surface 22 of the vehicle roof 20 is an inclined surface, and the lower end surface 22 is parallel to the upper end surface 12. The above structure can form a V-shaped groove structure at the upper end of the side wall 10, that is, the upper end surface 12 of the side wall 10 and the support plate 11 form a V-shaped groove structure, and the lower end surface 22 of the vehicle roof 20 and the inner side surface of the vehicle roof 20 form a V-shaped protrusion structure. By the mutual cooperation of the V-shaped protrusion structure and the V-shaped groove structure, the connection stability between the vehicle roof 20 and the side wall 10 can be effectively improved. Further, the connecting plate 21, the lower end surface 22 and the inner side surface of the vehicle roof 20 of the vehicle roof 20 form a Z-shaped structure. Correspondingly, the outer side surface, the upper end surface 12 and the support plate 11 of the side wall 10 also form a Z-shaped structure. By the cooperation of the two Z-shaped structures, the connection stability between the vehicle roof 20 and the side wall 10 can be further improved.

[0036] In some embodiments, the support plate 11 and the side wall 10 are of an integrally formed structure, and the connecting plate 21 and the roof 20 are of an integrally formed structure. For example, pultrusion can be used for integral forming. Through the integrally formed structure, the number of parts can be reduced, which is convenient for assembly and improves the assembly efficiency.

[0037] An embodiment of the present utility model further provides a vehicle body, which includes the connection structure between the side wall 10 and the roof 20 provided in any of the above embodiments. In addition, it further includes a chassis. The bottom of the side wall 10 is connected to the chassis. Regarding the beneficial effects of the vehicle body, reference can be made to the beneficial effects of the connection structure between the side wall 10 and the roof 20 above, which will not be elaborated here. In addition, for the vehicle body, a side wall side beam can be provided at the upper end of the other side wall corresponding to the above side wall 10. For the sake of distinction, this side wall is denoted as the opposite side wall. A roof side beam is provided at the lower end of the roof. The upper end of the roof side beam is connected to the roof, the lower end of the roof side beam is connected to the upper end of the side wall side beam, and the lower end of the side wall side beam is connected to the upper end of the opposite side wall. For the convenience of connecting the air conditioner, a support platform extending towards the interior of the vehicle body can be provided inside the upper end of the side wall side beam, and a connection platform extending towards the interior of the vehicle body can be provided inside the lower end of the roof side beam. The support platform and the connection platform can be connected by rivets or bolts to form an air conditioner platform, that is, the support platform and the connection platform can play a connecting role and also play a role in installing the air conditioner.

[0038] An embodiment of the present utility model further provides a rail vehicle, which includes the above vehicle body and further includes a driving device, and the driving device can drive the vehicle body to move. Regarding the beneficial effects of the rail vehicle, reference can be made to the beneficial effects of the connection structure between the side wall 10 and the roof 20 above, which will not be elaborated here.
